The main functions of the indexing disc are: 1. Intermittent conveying in the circumferential direction. 2. Intermittent conveying in the straight direction. 3. Swing and drive the robotic arm. 4. Achieve precise segmentation.
Dividing discs have been widely used in automated production lines and various general mechanical equipment such as packaging, electronic appliances, glass ceramics, printing, pharmaceuticals, chemicals, tobacco, automotive manufacturing, etc. They play a crucial role as the core transmission device of automated machines
Cam indices, also known as cam dividers, intermittent dividers, cam indexing mechanisms, cam indexing boxes, arc indexing discs, parallel indexing discs, flat indexing discs, cylindrical cam indexing mechanisms, etc., are currently the most precise, reliable, and stable intermittent transmission mechanism in the world. Through this mechanism, continuous input motion can be converted into intermittent indexing motion. The conjugate cam on the input shaft and the indexing wheel on the output shaft mesh vertically (parallel) without any gap. The curved segment of the cam profile on the input shaft drives the indexing wheel to rotate, while the straight segment makes the indexing wheel stationary and self-locking. Normally, for every 360 ° rotation of the input axis, the output axis completes a indexing motion (stationary and indexing) simultaneously. During a indexing motion, the ratio of time the output shaft runs to rest is determined by the driving angle of the cam. The so-called cam drive angle refers to the angle at which the input cam drives the output shaft to rotate for indexing. The larger the angle, the smoother the operation of the mechanism. When the input shaft completes the driving angle, the output shaft begins to come to a standstill. The angle at which the input shaft rotates when the output shaft is stationary is called the stationary angle, and the sum of this angle and the driving angle is 360 degrees.
The standard curve of SANHER's cam divider consists of the following four types:
1. Deformable trapezoidal curve (MT): suitable for high-speed and light loads;
2. Deformable Sine Curve (MS): Suitable for medium/high speeds and moderate loads;
3. Deformation Constant Velocity Curve (MCV50): Suitable for low speeds and heavy loads.
The connection between the input shaft and output shaft of the indexing plate must pay attention to axial alignment and avoid leaving any gaps. Gears, couplings, pulleys, sprockets, and circular turntables can be used; According to different usage scenarios in different factories, the input shaft can be equipped with positioning cam and sensor, brake, electromagnetic clutch, etc., and the output shaft can be equipped with torque limiter
