Description

Technical Field

[0001] This utility model relates to the field of automatic processing equipment technology, and specifically to a cam divider. Background Technology

[0002] A cam divider, also commonly known as an intermittent divider, is a mechanism that enables intermittent motion. It features high indexing accuracy, smooth operation, high torque transmission, self-locking during positioning, compact structure, small size, low noise, good high-speed performance, and long service life. The heavy-duty cam divider is one type of cam divider.

[0003] Traditional cam intermittent dividers typically employ a one-piece output turret structure. While this structure offers a degree of precision and stability, it also presents several limitations. The manufacturing process for a one-piece output turret is complex, requiring high-precision machining equipment and technology, resulting in high production costs. Furthermore, damage to any part of the output turret makes repairs extremely inconvenient, often necessitating the replacement of the entire turret or even the entire divider, leading to resource waste and increased costs. In addition, the relatively fixed structure of a one-piece output turret makes it difficult to flexibly customize and modify for different application scenarios and equipment requirements, lacking adaptability and scalability. With the continuous development of industrial automation, the demands for cost control, ease of maintenance, and personalized customization of cam intermittent dividers are increasing. The traditional one-piece output turret structure can no longer meet these needs; therefore, the development of a new type of split-type output turret structure is urgently needed.

[0029] Reference Figures 1 to 5 This utility model provides a cam divider, which includes a base 1, a housing 2 disposed above the base 1, an input shaft 4 disposed inside the housing 2 and extending out of the housing 2, an arc-shaped cam 8 fixed on the input shaft 4, a split-type output turret 9 that meshes with the arc-shaped cam 8 and is disposed perpendicular to the input shaft 4, a drive motor 5 fixed on the outside of the housing 2, and a transmission assembly disposed between the drive motor 5 and the input shaft 4.

[0030] In some embodiments, the split-type output turret 9 is provided with a plurality of needle roller bearings 91 along the circumference, and the plurality of needle roller bearings 91 mesh with the arc-shaped cam 8.

[0031] In some embodiments, the top plate of the housing 2 has bearing holes, and the split-type output turret 9 extends out of the housing 2 from the bearing holes. The split-type output turret 9 includes an output turret body, a connecting shaft section, and a fastening device. The output turret body is made of high-strength alloy steel, and one end of the output turret body is provided with a keyway and a positioning plane. The output turret body is connected to the housing 2 by a turntable bearing. The other end of the output turret body is provided with an internal threaded hole. The connecting shaft section is cylindrical, and one end of the connecting shaft section is provided with an external thread that mates with the internal threaded hole. The threaded connection enables a detachable connection between the connecting shaft section and the output turret body, ensuring precise connection and concentricity between the output turret body and the connecting shaft section. The other end of the connecting shaft section is provided with a connection interface, which can be configured as a flange structure or a spline structure, etc., depending on actual needs, to facilitate connection with external equipment or transmission components. The fastening device includes a fastening nut and a lock washer. The fastening nut is threaded externally and mates with an internally threaded hole, further ensuring a secure connection between the connecting shaft section and the output turret body. The lock washer is positioned between the fastening nut and the lock washer to prevent the fastening nut from loosening during equipment operation.

[0032] In some embodiments, the split-type output turret 9 also includes a concentricity adjustment device, which includes adjusting shims and fine-tuning bolts. The adjusting shims are disposed between the mating end faces of the connecting shaft section and the output turret body. The adjusting shims have different thicknesses; by replacing adjusting shims of different thicknesses, the overall length and concentricity of the split-type output turret 9 can be initially adjusted. The fine-tuning bolts are evenly distributed in the circumferential direction of the output turret body, with one end passing through the output turret body and pressing against the outer circumferential surface of the connecting shaft section. By rotating the fine-tuning bolts, the radial position of the connecting shaft section relative to the output turret body can be precisely fine-tuned, thereby further improving the concentricity of the split-type output turret 9 and ensuring the stability and accuracy of the cam intermittent divider during operation.

[0033] During assembly, the external thread of the connecting shaft section is screwed into the internal threaded hole of the output turret body and initially tightened. Then, based on the pre-measured concentricity error, an adjusting shim of appropriate thickness is placed between the mating end faces of the connecting shaft section and the output turret body. Next, the radial position of the connecting shaft section is gradually adjusted by rotating the fine-tuning bolts, while using professional measuring instruments (such as a laser interferometer) to monitor the concentricity of the split-type output turret 9 in real time until the design-required concentricity accuracy is achieved. Finally, the fastening nut is tightened and the anti-loosening washer is installed, completing the assembly of the entire split-type output turret 9 structure.

[0034] During the use of the cam intermittent divider, regularly check the tightness of the fastening nuts and the concentricity of the split output turret 9. If any concentricity deviation is found, it can be readjusted using the fine-tuning bolts to ensure the continuous and stable operation of the equipment.

[0035] The split-type output turret 9 of this utility model has a split structure, including the output turret body, the connecting shaft section and the fastening device. It solves the problems of accuracy, stability and maintenance in the traditional integral output turret design. It has the advantages of simple structure, high accuracy, strong stability and convenient maintenance. It is suitable for various high-precision, high-load and high-frequency operation occasions, and provides a more reliable and efficient solution for the widespread application of cam intermittent dividers.
