Description

Technical Field

[0001] This utility model relates to the field of cam dividing technology, specifically a self-protecting heavy-duty cam divider. Background Technology

[0002] A cam divider, also known in engineering as a cam indexer or intermittent divider, is a high-precision rotary device. In today's automation environment, cam dividers are particularly important and widely used in production lines. Their principle is similar to a worm gear, using a cam to drive rollers to rotate and stop, thus causing the output shaft to rotate intermittently. The cam divider is driven by a motor, and to prevent excessive torque from damaging the rollers, a torque limiter is often installed, giving the cam divider a self-protection function.

[0003] In modern cam dividers, mechanical stress is generated during operation due to high-speed rotation and frequent starts and stops, causing the divider's rotation direction to shift.

[0004] To address the aforementioned issues, a self-protecting heavy-duty cam divider is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a self-protecting heavy-duty cam divider, which solves the problem in the background art where the mechanical stress generated during the operation of current cam dividers due to high-speed rotation and frequent start-stop cycles causes displacement of the divider's rotation direction.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a self-protecting heavy-duty cam divider, comprising a divider outer casing, a drive mechanism rotatably disposed inside the divider outer casing, an output mechanism movably engaged on one side of the drive mechanism, the divider outer casing comprising a housing, a conical groove being formed inside the housing, the drive mechanism comprising a cam component rotatably disposed inside the housing, the output mechanism comprising cam rollers rotatably engaged with the cam component, the cam rollers comprising multiple sets arranged in a circular array, a turntable connecting the multiple sets of cam rollers, two sets of conical components fixedly disposed on both sides of the turntable, and ball bearings rotatably engaged on the conical components.

[0007] Preferably, the outer casing of the divider has an embedded groove at the position corresponding to the drive mechanism, and roller pads are provided on both sides of the embedded groove.

[0008] Preferably, a connecting frame is fixedly provided on one side of the housing, and a threaded rod is threaded onto one end of the connecting frame.

[0009] Preferably, the drive mechanism further includes an input shaft fixedly disposed inside the housing, and the input shaft is fixed to a cam component.

[0010] Preferably, a limiting element is provided at one end of the input shaft corresponding to the threaded rod.

[0011] Preferably, both ends of the turntable are fixed with conical parts and ball bearings, and two conical grooves are correspondingly formed.

[0012] Preferably, the output mechanism further includes an output shaft fixedly disposed at the center of the turntable.

[0013] Preferably, the cam roller and the cam component are sized to fit each other, and the cam roller is movably sleeved in the gap of the cam component.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. The present invention provides a self-protecting heavy-duty cam divider, which increases the rotation contact surface and improves stability by setting a conical groove inside the divider's outer casing. This initially solves the problem that the mechanical stress generated during the operation of current cam dividers due to high-speed rotation and frequent start-stop cycles causes the divider's rotation direction to shift.

[0016] 2. This utility model provides a self-protecting heavy-duty cam divider. Through the setting of the output mechanism, the cam component is connected to an external motor for rotation. The turntable is movably engaged in the outer box of the divider. The tapered components on both sides of the turntable are adapted to the opening of the tapered groove. The ball bearings are rotatably set between the tapered components and the tapered groove. The tapered design of the tapered components helps the output mechanism maintain a good contact state during the movement, making the movement more stable, reducing noise, and preventing deviation. In addition, the setting of the ball bearings increases the contact area between the two moving surfaces, disperses the contact stress, and reduces local wear. This solves the problem that in current cam dividers, mechanical stress is generated during operation due to high-speed rotation and frequent start-stop, causing the divider's rotation direction to shift.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0025] Combination Figure 1 This utility model discloses a self-protecting heavy-duty cam divider, including a divider outer housing 1. A drive mechanism 2 is rotatably arranged inside the divider outer housing 1. An output mechanism 3 is movably engaged on one side of the drive mechanism 2. The divider outer housing 1 includes a housing 11, and a conical groove 111 is opened inside the housing 11. The drive mechanism 2 includes a cam component 22 rotatably arranged inside the housing 11. The output mechanism 3 includes cam rollers 32 rotatably engaged with the cam component 22. Multiple sets of cam rollers 32 are arranged in a circular array. A turntable 31 is connected between the multiple sets of cam rollers 32. Two sets of conical components 33 are fixedly arranged on both sides of the turntable 31. Ball bearings 34 are rotatably engaged on the conical components 33.

[0026] Specifically, the housing 11 serves a fixing function, and the cam component 22 is externally connected to a motor for rotation. The cam component 22 is the core part of the divider, and its shape determines the characteristics of the output motion, namely the dividing angle and speed. The cam roller 32 works in conjunction with the cam component 22 to drive the output mechanism 3 to perform intermittent motion. The turntable 31 is movably engaged inside the outer housing 1 of the divider. The tapered components 33 on both sides of the turntable 31 are adapted to the openings of the tapered groove 111. The ball bearings 34 are rotatably arranged between the tapered components 33 and the tapered groove 111. The tapered design of the tapered component 33 helps the output mechanism 3 maintain a good contact state during the movement, making the movement more stable, reducing noise, and preventing deviation. In addition, the arrangement of the ball bearings 34 increases the contact area between the two moving surfaces, disperses the contact stress, and reduces local wear.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] Example 1:

[0029] Combination Figures 2-5 The outer casing 1 of the divider is provided with an embedded groove 12 corresponding to the position of the drive mechanism 2. Roller pads 13 are provided on both sides of the embedded groove 12. The embedded groove 12 provides an environment for the rotation of the drive mechanism 2, and the roller pads 13 reduce the friction at both ends when the drive mechanism 2 rotates.

[0030] A connecting frame 14 is fixedly installed on one side of the housing 11. A threaded rod 15 is threaded on one end of the connecting frame 14. The connecting frame 14 is used to fix the threaded rod 15. The threaded rod 15 cooperates with the drive mechanism 2 to complete the rotation limit.

[0031] The drive mechanism 2 also includes an input shaft 21 fixedly installed inside the housing 11. The input shaft 21 is fixed with a cam component 22. One end of the input shaft 21 is connected to a motor. The input shaft 21 drives the cam component 22 to rotate, thereby driving the output mechanism 3.

[0032] One end of the input shaft 21 is provided with a limiting element 23 corresponding to the threaded rod 15. The limiting element 23 is an irregular rotating block, which works with the threaded rod 15 to achieve rotational limitation.

[0033] Example 2:

[0034] Combination Figure 5 Both ends of the turntable 31 are fixed with tapered parts 33 and ball bearings 34. Two tapered grooves 111 are opened accordingly. The combination of tapered parts 33 and ball bearings 34 at both ends enhances the stability of the rotating structure and allows both sides to adapt to the changes in the cam curve, thereby improving the motion accuracy.

[0035] The output mechanism 3 also includes an output shaft 35 fixedly installed at the center of the turntable 31. The output shaft 35 protrudes outward to realize rotation control of the output end components.

[0036] The cam roller 32 and the cam component 22 are sized to fit each other. The cam roller 32 is movably sleeved in the gap of the cam component 22, and the cam roller 32 and the cam component 22 rotate in a matching manner.
