Description

Technical Field

[0001] This utility model relates to the field of gear assembly technology, specifically to an actuator gear positioning pin guided assembly mechanism. Background Technology

[0002] The actuator gear positioning pin guiding assembly mechanism is a mechanical device used in automated assembly equipment for the precise positioning and guidance of gear parts. Its core function is to ensure that the gears achieve high-precision positioning during the assembly process through the guidance of the positioning pin, so as to avoid transmission failure, noise or equipment failure caused by assembly deviation.

[0003] In the prior art, such as the actuator gear positioning pin guiding assembly mechanism disclosed in CN119017033A, the gear is stably adsorbed onto the gear shaft through the vacuum adsorption effect of the vacuum suction mechanism. During the adsorption process, the gear shaft can float up and down in the internal cavity of the mechanism body. Combined with the drive device and displacement sensor, the meshing situation can be detected during the descent of the gear, further ensuring the assembly accuracy after adsorption.

[0004] The vacuum suction mechanism and the lower shaft work together to form an adsorption structure to achieve gear adsorption. However, for gears with non-planar surfaces and small contact areas, the contact area and the lower shaft are insufficient to form a closed space, and the vacuum suction mechanism cannot work with the lower shaft to pick up the gear. Therefore, we propose an actuator gear positioning pin guiding assembly mechanism. Utility Model Content

[0005] One of the technical problems to be solved by this application is that the existing device has a poor adsorption effect on gears with non-fully planar contact surfaces and small contact surfaces, which leads to the failure of gear adsorption.

[0006] To solve the above-mentioned technical problems, this application provides an actuator gear positioning pin guiding assembly mechanism, including an assembly machine, a guiding mechanism, a vacuum valve, a suction nozzle, and a pipe. The guiding mechanism slides inside the assembly machine, and a pipe is provided inside the guiding mechanism. A vacuum valve is provided on the left side of the guiding mechanism, and a plurality of evenly distributed suction nozzles are rotatably connected to the upper part of the guiding mechanism. A limiting member for restricting the rotation of the suction nozzle is provided inside the suction nozzle.

[0007] Preferably, the limiting component includes multiple limiting plates installed inside the guiding mechanism, a limiting shaft rotatably connected inside the limiting plates, the outer wall of the suction nozzle being disposed at the rear end of the limiting shaft, multiple evenly distributed limiting blocks rotatably connected at the edge of the limiting shaft, multiple evenly distributed springs disposed at the edge of the limiting shaft, the distal ends of the springs abutting against the outer wall of the limiting blocks, one end of the limiting shaft being disposed at the outer wall of the suction nozzle, and a driving component for driving the limiting plates to move being disposed inside the guiding mechanism.

[0008] Preferably, the driving component includes an electric push rod disposed inside the guiding mechanism, a driving block is disposed on the upper part of the electric push rod, the rear side of the driving block is disposed on the front part of the limiting plate, and a guide for stabilizing the sliding of the driving block is disposed inside the guiding mechanism;

[0009] The guide includes a guide block disposed on the outer wall of the drive block, and a guide groove is provided inside the guide mechanism, and the guide block slides inside the guide groove.

[0010] Preferably, the guide mechanism has a plurality of evenly distributed stop bars rotatably connected inside, with the middle part of the stop bars located at the rear end of the limiting shaft.

[0011] Preferably, the suction nozzle includes a through tube rotatably connected inside the guide mechanism, with magnets provided on both the left and right sides of the through tube, and the edge of the stop bar located at the lower part of the suction nozzle.

[0012] Preferably, the through pipe and the conduit overlap each other.

[0013] Preferably, the guide mechanism has a plurality of evenly distributed sliding plates inside, and the suction nozzle abuts against the edge of the sliding plates.

[0014] Preferably, the limiting plate has a toothed groove at its edge, and the guide mechanism has a plurality of evenly distributed toothed plates inside, with the limiting plate meshing with the middle of the toothed plates, and the upper part of the toothed plates being smooth.

[0015] This utility model has at least the following beneficial effects:

[0016] 1. The internal limiting components of the suction nozzle achieve unidirectional rotation control through limiting plates, limiting shafts, limiting blocks, and springs. Adjacent limiting components are mirror-symmetrical to control rotation in different directions.

[0017] 2. The electric actuator drives the drive block to move, and the stop bar moves up and down in the suction nozzle to push it to rotate or be pushed to rotate. The suction nozzle's through tube and the pipe form a vacuum channel. After the magnet rotates, it replaces the position of the channel. The slider guides the suction nozzle to rotate back to its original position. The electric actuator drives the suction nozzle to move up and down and cooperates with the stop bar, slider, etc. to make the suction nozzle rotate 90 degrees to achieve adsorption switching and adapt to the gripping needs of different gears.

[0025] 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.

[0026] Example 1: Please refer to Figure 1 , Figure 2 and Figure 4 This utility model provides a technical solution: an actuator gear positioning pin guiding assembly mechanism, including an assembly machine 1, a guiding mechanism 11, a vacuum valve 12, a suction nozzle 13 and a pipe 14. The guiding mechanism 11 slides inside the assembly machine 1. The pipe 14 is opened inside the guiding mechanism 11. The vacuum valve 12 is arranged on the left side of the guiding mechanism 11. Multiple evenly distributed suction nozzles 13 are rotatably connected to the upper part of the guiding mechanism 11. The suction nozzles 13 are provided with limiting members 2 for limiting the rotation of the suction nozzles 13.

[0027] Assembly machine 1 can provide internal structural support, guide mechanism 11 is used to position gears, vacuum valve 12 is used to cooperate with pipe 14 to form a power source and suction nozzle 13 to pick up gears.

[0028] Furthermore, the limiting member 2 includes multiple limiting plates 21 installed inside the guide mechanism 11. A limiting shaft 22 is rotatably connected inside the limiting plate 21. The outer wall of the suction nozzle 13 is located at the rear end of the limiting shaft 22. Multiple evenly distributed limiting blocks 23 are rotatably connected at the edge of the limiting shaft 22. Multiple evenly distributed springs 24 are located at the edge of the limiting shaft 22. The distal ends of the springs 24 abut against the outer wall of the limiting blocks 23. One end of the limiting shaft 22 is located on the outer wall of the suction nozzle 13. A driving member 3 for driving the limiting plate 21 to move is provided inside the guide mechanism 11.

[0029] The limiting plate 21 is used to provide internal structural protection, the limiting shaft 22 is used to provide mounting support for the limiting block 23 and the spring 24, the limiting block 23 can cooperate with the limiting plate 21 to make the limiting shaft 22 rotate only in one direction, and the spring 24 is used to push the limiting block 23 to rotate and press it against the inner wall of the limiting plate 21.

[0030] The two adjacent limiting members 2 are arranged in a mirror symmetry, which allows for unidirectional rotation of the stop bar 16 and the suction nozzle 13 in different directions.

[0031] Example 2: Please refer to Figure 3 and Figure 4 The driving component 3 includes an electric push rod 31 disposed inside the guide mechanism 11. A driving block 32 is disposed on the upper part of the electric push rod 31. The rear side of the driving block 32 is disposed on the front part of the limiting plate 21. A guide 4 for stabilizing the sliding of the driving block 32 is disposed inside the guide mechanism 11.

[0032] The guide 4 includes a guide block 41 disposed on the outer wall of the drive block 32, and a guide groove 42 is provided inside the guide mechanism 11, and the guide block 41 slides inside the guide groove 42.

[0033] The electric actuator 31 can pull the drive block 32 to move. The drive block 32 is used to drive the limiting plate 21 to slide. The guide block 41 and the guide groove 42 cooperate to stabilize the sliding of the drive block 32.

[0034] Example 3: Please refer to Figure 4 The guide mechanism 11 has multiple evenly distributed baffles 16 rotatably connected inside, with the middle part of the baffles 16 located at the rear end of the limiting shaft 22;

[0035] The stop lever 16 and the limiting member 2 cooperate to push the suction nozzle 13 to rotate when the suction nozzle 13 moves downward, and push the stop lever 16 to rotate when the suction nozzle 13 moves upward.

[0036] Example 4: Please refer to Figure 3 , Figure 4 and Figure 5The suction nozzle 13 includes a through tube 131 rotatably connected inside the guide mechanism 11. Magnets 132 are provided on both the left and right sides of the through tube 131. The edge of the stop bar 16 is located at the lower part of the suction nozzle 13.

[0037] Furthermore, the conduit 131 and the pipe 14 overlap each other.

[0038] Furthermore, the guide mechanism 11 has multiple evenly distributed sliding plates 15 inside, and the suction nozzle 13 abuts against the edge of the sliding plate 15.

[0039] The through pipe 131 and the pipe 14 form a vacuum channel, which can form a vacuum space with the cooperation of the vacuum valve 12 to attract gears. The magnet 132 can be flush with the upper part of the guide mechanism 11 after rotation, thereby attracting gears. The slider 15 is used to guide the rotation of the suction nozzle 13 back to its original position. When the suction nozzle 13 rotates and moves upward, the slider 15 can push the suction nozzle 13 to keep it rotating 90 degrees at a time and aligning with the upper part of the guide mechanism 11.

[0040] When the electric actuator 31 is activated, it drives the drive block 32 and the limiting member 2 to move downwards. The limiting member 2 drives the suction nozzle 13 to move downwards. When one side of the suction nozzle 13 presses against one side of the stop rod 16, the magnet 132 is pushed to rotate by the stop rod 16. The suction nozzle 13 drives the limiting shaft 22 to rotate, and the limiting shaft 22 drives the limiting block 23 to rotate. The limiting block 23 is pushed by the limiting plate 21 to deform the spring 24. When the suction nozzle 13 is released from the push of the stop rod 16, the suction nozzle 13 rotates ninety degrees. Then, the electric actuator 31 pushes the drive block 32 to move upwards. When the suction nozzle 13 moves, it pushes the stop lever 16 to rotate. After the suction nozzle 13 leaves the rotation area of ​​the stop lever 16, the stop lever 16 is pushed to rotate 90 degrees. Then the suction nozzle 13 continues to move upward. Under the push of the slider 15, the suction nozzle 13 can be accurately reset to rotate 90 degrees. When the suction nozzle 13 slides to the upper part of the pipe 14, the suction nozzle 13 closes the pipe 14 and coincides with the upper surface of the guide mechanism 11. This enables the suction nozzle 13 to switch between adsorption functions to adapt to the adsorption and gripping functions of different types of gears.

[0041] Example 5: Please refer to Figure 6 Based on Embodiment 1, this utility model provides another technical solution: the edge of the limiting plate 21 is provided with a toothed groove, and the guide mechanism 11 is provided with a plurality of evenly distributed toothed plates 25. The limiting plate 21 is engaged in the middle of the toothed plates 25, and the upper part of the toothed plates 25 is smooth.

[0042] The outer wall of the limiting plate 21 is provided with a toothed groove, which cooperates with the toothed plate 25. The limiting plate 21 can be pushed and rotated by the toothed plate 25 when it moves downward. The upper part of the toothed plate 25 cannot push the limiting plate 21 to rotate. This allows the limiting member 2 to maintain vertical movement when it initially moves downward, and then rotate to drive the suction nozzle 13 to rotate.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
