Cam Indexer

Cam indexer, also known as intermittent indexer, its structure is relatively simple, but because of its own precision and required accuracy are relatively high, so the installation work before use is more important, must be strictly followed by professional technicians Request to proceed.

When installing the cam indexer, check the surface of the equipment for damage and oil leakage, confirm whether there is sufficient oil level in the oil glass, confirm the required model, and install the required peripheral components in advance.

After all confirmations are completed , the fastening screws need to be tightened with gaskets, and diagonally fastened. Before use, it must be strictly debugged before it can be put into use.

During the installation process, determine the installation method according to the use of the drive source and the connecting equipment of the output shaft. For the installation of chains and belts, pay attention to the adjustment of the gap. Including the smooth rotation of the input shaft and output shaft when the indexer is fixed.

Because the cam indexer is a professional transmission component, the user must strictly follow the requirements during the internal installation or disassembly of the body. If maintenance or repair is required, they cannot be adjusted and disassembled without authorization to avoid Causes many adverse effects on the product itself, or affects its service and quality performance.

Cam indexer is a high-precision rotation positioning device with high rotation repeat positioning accuracy. Its structure includes input shaft, cam, needle bearing, output tower, box, etc. The movement principle is that the input cam mechanism drives the output tower, and the indexing movement is achieved under the action of the driving source.

Since the structural surface of the cam is mainly a complex sinusoidal machined surface, after contact with the turret roller cam, the mechanical movement is moved and stopped. the intermittent movement of the cam indexer is completely completed mechanically, and its stability is not as good as other non-mechanical equipment.

Servo motor refers to the engine that controls the operation of the mechanical components of the servo system and is an indirect transmission device for the auxiliary motor. Servo motors can control speed and position accuracy very accurately, and convert voltage signals into torque and speed to drive control objects. The rotation speed of the servo motor rotor is controlled by the input signal and responds quickly. In automatic control systems, it is used as an actuator and has the characteristics of small electromechanical time, high linearity and high starting voltage.

The received electrical signal can be converted into an angular displacement or angular velocity output on the motor shaft. It can be divided into DC and AC servo motors. Its main feature is that there is no rotation when the signal voltage is zero, and the rotation speed decreases at a
constant speed as the torque increases. DC servo requires brushing to change directions, the use speed is limited, the material is easy to wear, the AC servo control is complicated, the driving parameters need to be adjusted on-site, and the PID parameters need to be adjusted on-site, and the electronic circuit is complex.

You should know what the cam indexing table is for. The cam indexer is also called the intermittent divider. It is mainly used for the mechanical action of motion-stop-motion-stop infinite loop, such as automation The assembly of the disc, the belt or sprocket drive of the assembly line, all require the switching of stations and the processing action.

The filling machine in the beer and beverage factory is the same. One production action is completed, and the next processing action is switched. The completion of such continuous intermittent splitter action requires what we call a cam indexer.

The work that the cam indexer must complete before use is the selection of the indexer, because different cam dividers have different functions and functions. The first thing to do is to determine whether it is a disc type production processing method or a transmission type processing method.

If it is a disc type production method, then it is necessary to determine the number of processing stations, the driving angle of the input shaft, the rotation speed of the input shaft per minute, the diameter, thickness and material of the disc.

For transmission-type production and processing, it is generally called assembly line processing. The parameters that need to be considered in the selection of cam dividers are the number of machining positions, also called the number of divisions, the driving angle of the input axis, and the input axis per minute.

The rotation speed of the conveyor belt, the pitch circle diameter of the driving wheel and the driven wheel, the diameter, weight and number of the drive shaft, the diameter, weight and number of the sprocket pitch circle.

The weight of the chain, the weight of the fixture and the workpiece. Through the statistics of the above parameters, and then calculate according to the professional selection calculation software to get the model and category of the required cam indexer.

Under the premise that the model of the indexer is determined, it is necessary to confirm which drive source is used during use, such as gear reducer, stepper motor, servo motor, etc., which drive source to use, it is necessary to determine the function to be achieved by using the indexer. Integrate the entire automation requirements, and then make a final judgment based on the cost and efficiency status.

Cam indexers are the preferred choice for achieving zero backlash in high-precision manufacturing applications. Backlash is a measure of the play or clearance between two mating parts, and it can result in inaccuracies and errors in positioning and movement. Cam indexers are designed to eliminate backlash, making them the only real option for applications that require high precision and repeatability.

One of the primary reasons why cam indexers are the only real option for achieving zero backlash is their design. Cam indexers use a series of precisely machined cams and cam followers to achieve motion. The contact between the cam and cam followers is designed to be tight and precise, with very little clearance or play. This means that there is no room for backlash to occur.

Another reason why cam indexers are the only real option for achieving zero backlash is their construction. Cam indexers are typically built with high-quality materials that are designed to withstand high loads and high speeds.

The precision machining and construction of the cam indexers ensure that they maintain their accuracy and repeatability over long periods of use.

Cam indexers are designed to be highly customizable, which means that they can be tailored to specific applications. This allows for greater precision and control over the indexing motion, which can help to eliminate any potential for backlash. This customization can include everything from the cam shape and roller size to the material used for construction.
