Description

Technical Field

[0001] This utility model relates to the field of automated assembly equipment, specifically to a torque ball bearing assembly mechanism. Background Technology

[0002] During gearbox assembly, multiple torque balls are typically installed as clutch or overload protection components. Currently, this process is mostly done manually, with operators manually placing the torque balls into specific holes in the gearbox. This manual assembly method has significant drawbacks: First, due to the small size and large number of torque balls, they are prone to falling out during handling, affecting assembly efficiency; second, on fast-paced assembly lines, operators are prone to omitting torque balls due to fatigue or negligence, resulting in product quality defects; finally, the low efficiency of manual assembly has become a bottleneck restricting the overall capacity improvement of gearbox production lines.

[0003] Therefore, there is an urgent need for a specialized mechanism that can automate the assembly of torque ball bearings with high efficiency and effectively prevent omissions. Utility Model Content

[0004] To address the problems of easy falling off, missing parts, and low efficiency caused by relying on manual assembly of torque balls in existing technologies, this utility model provides a torque ball assembly mechanism with a high degree of automation, reliable assembly, and missing part detection function.

[0005] A torque ball assembly mechanism includes a support component, a torque ball feeding and distributing component, a detection component, and a testing component.

[0006] The support assembly includes support columns, an upper fixing plate, and a lower fixing plate. The upper fixing plate and the lower fixing plate are fixedly connected by multiple support columns to form a stable frame structure.

[0007] The torque ball bearing feeding and distributing assembly includes a torque ball bearing feeder, a torque ball bearing distributing air rod, and a torque ball bearing inlet. The torque ball bearing inlet is fixed to the lower fixed plate, with its inlet end connected to the outlet end of the torque ball bearing feeder to receive and temporarily store the torque balls. The torque ball bearing distributing air rod is located on the side of the torque ball bearing inlet, with its output end connected to a distributing plate located below the torque ball bearing inlet. The distributing plate has a material hole adapted to the bottom outlet of the torque ball bearing inlet. When the torque ball bearing distributing air rod drives the distributing plate to move horizontally, the material hole can receive the lowest torque ball inside the torque ball bearing inlet and move it horizontally to directly above the gearbox assembly hole below, allowing the torque ball to fall into the hole by its own weight.

[0008] The detection assembly includes a torque ball bearing detection cylinder and detection rods. The torque ball bearing detection cylinder is fixed to the upper fixed plate. Multiple detection rods are provided and are movably positioned below the output end of the torque ball bearing detection cylinder. The lower end of each detection rod corresponds to a mounting hole in the gearbox, and the torque ball bearing detection cylinder can drive the detection rods to move up and down synchronously in the vertical direction.

[0009] The detection component includes a detection switch, which senses the relative position change of the detection rod due to contact with the torque ball. When the detection rod moves down to its position and touches the positioned torque ball, the detection rod is lifted by an upward reaction force, thereby triggering the detection switch. If the torque ball is missing from the workstation, the detection rod falls directly without being lifted, and the detection switch is not triggered. The system then determines that the ball is missing.

[0010] Preferably, there are six detection rods, which are evenly distributed around the output end of the torque ball detection cylinder; there are two torque ball dispensing rods arranged symmetrically, and each dispensing plate has three material holes, so that the overall movement of the mechanism can dispense six torque balls.

[0011] Preferably, the lower fixed plate is provided with multiple vertical guide rods, and a sleeve is installed at the output end of the torque ball bearing detection cylinder. The sleeve is movably connected to the guide rods through a linear bearing to ensure smooth overall lifting. Each detection rod has a through hole inside the sleeve, allowing it to move up and down independently; and each through hole contains a larger diameter expansion hole. The diameter of the detection rod matches the through hole, and a limiting post is provided at its upper end, the diameter of which matches the expansion hole. This structure allows the detection rod to move up and down within the through hole to a limited extent, while the cooperation of the limiting post and the expansion hole effectively prevents the detection rod from falling out of the sleeve or being excessively pushed out.

[0012] The beneficial effects of this utility model are: Automated assembly, high efficiency: The automated process of material sorting, assembly, and testing replaces inefficient manual operations, significantly improving assembly efficiency and making it suitable for automated production lines.

[0013] The detection is direct and reliable: it uses the physical phenomenon of the detection rod being lifted after contacting the torque ball. The principle is direct, the anti-interference ability is strong, and the false negative and false positive rates are low, which greatly improves the reliability of the detection.

Detailed Implementation

[0015] 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.

[0016] Reference Figures 1 to 4 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.

[0017] Reference Figures 1 to 2 The torque ball bearing assembly mechanism shown has a support component consisting of multiple support columns 101, an upper fixed plate 102, and a lower fixed plate 103 connected together to form the main frame.

[0018] In the torque ball bearing feeding and distribution assembly, a vibratory feeder 201 transports torque balls in an orderly manner through pipes to a torque ball bearing feeder 203 vertically fixed above the base plate. Two torque ball bearing distribution air rods 202 are symmetrically arranged, driving their respective distribution plates 202a to perform horizontal reciprocating motion at the bottom of the torque ball bearing feeder 203. During the movement, the material holes 202b on the distribution plates 202a receive the torque balls and precisely transport them to the corresponding holes in the gearbox to be assembled, allowing them to fall into the holes.

[0019] In the torque ball bearing press assembly, the torque ball bearing detection cylinder 301 is fixed to the upper fixed plate 102, and its piston rod is connected downward to a sleeve 6. The sleeve 6 cooperates with multiple guide rods 5 fixed on the lower fixed plate 103, and can move smoothly up and down in the vertical direction. The sleeve 6 is provided with multiple through holes, and each detection rod 302 passes through one through hole. The limiting post 302a at the upper end of the detection rod 302 cooperates with the enlarged section in the through hole, so that it can move up and down slightly relative to the sleeve 6 without falling out.

[0020] In the detection assembly 4, the triggering mechanism of the detection switch is linked to the upward movement of the detection rod 302. When the mechanism is working, the torque ball detection cylinder 301 drives the sleeve 6 and all detection rods 302 downward. If there is already a torque ball in a certain assembly hole, the lower end of the corresponding detection rod 302 will touch the ball and will not be able to continue downward. Instead, it will be lifted relative to the sleeve 6, which continues to move downward, thus triggering the detection switch. If a hole is missing an assembly rod, the detection rod 302 will fall directly to the bottom with the sleeve 6 without lifting, and the detection switch will not be triggered. The control system can accurately determine the assembly status of each station based on the trigger signals of each detection switch.

[0021] 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, the scope of which is defined by the appended claims and their equivalents.
