Description

Technical Field

[0001] This invention relates to the field of fastener technology, specifically to a bolt and nut processing and assembly device. Background Technology

[0002] Bolts are commonly used industrial parts. For the adjustment of vehicle chassis suspension, a positioning bolt assembly for adjusting the camber angle of the lower control arm has been developed for four-wheel alignment of the vehicle.

[0003] like Figure 1 and Figure 2 As shown, the positioning bolt assembly includes a bolt 1, a washer 2, and a nut 3. The bolt shank of the bolt 1 is located eccentrically at the head of the bolt 1. The bolt shank of the bolt 1 has a guide groove 4. The washer 2 has a hexagonal prism-shaped limiting part 5, the shape and size of which are consistent with the external shape of the nut 3. The washer 2 also has a protrusion 6 that can extend into the guide groove 4. In use, the bolt 1 is passed through the mounting holes of the subframe and the lower control arm, and the washer 2 is placed on the bolt 1, so that the protrusion 6 slides into the guide groove 4, and the limiting part 5 is engaged. In the subframe limiting notch, the shape of the limiting notch is consistent with that of the limiting part 5. By utilizing the cooperation between the shape of the limiting notch and the limiting part 5, as well as the cooperation between the protrusion 6 and the guide groove 4, the bolt 1 cannot rotate in the subframe and the lower control arm, thus preventing the position of the screw from changing. When it is necessary to adjust the camber angle, the angle at which the limiting part 5 slides into the subframe limiting notch is changed, thereby changing the position of the screw and thus changing the camber angle of the lower control arm. When the adjustment is appropriate, the nut 3 is locked on the screw to complete the adjustment of the camber angle of the lower control arm.

[0004] Since the screw, nut 3, and bolt 1 are used together and will be packaged and sold as a whole product, and since the washer 2 needs to be fitted at a specific angle when it is fitted onto the screw, and bolt 1 is set eccentrically, conventional bolt and nut automatic assembly equipment cannot be used for bolt 1.

[0005] Therefore, this application provides a technical solution to solve this technical problem. Summary of the Invention

[0006] The purpose of this invention is to solve the problems in the prior art by proposing a bolt and nut processing and assembly device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A bolt and nut processing and assembly device includes a workbench and bolt rails, washer rails, nut rails and assembly rails installed on the workbench. The assembly rails and bolt rails are connected. The workbench is equipped with a picking component via a lifting turntable. The picking component is used to pick up washers and nuts.

[0013] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0014] like Figure 3 As shown, this application provides a bolt and nut processing and assembly device that can assemble existing positioning bolt 1 assemblies. The device includes a workbench 7, a bolt track 8, a washer track 9, a nut track 10, and an assembly track 11. The bolt track 8 and assembly track 11 are connected. All three tracks are fixedly mounted on the workbench 7. One end of each track is connected to three vibratory feeders. The three vibratory feeders respectively hold the bolt 1, washer 2, and nut 3, and convey them out in a specific manner. The spatial cross-sections of the bolt track 8, washer track 9, nut track 10, and assembly track 11 are all convex, preventing detachment during transport.

[0015] like Figure 3 and Figure 4 As shown, the assembly track 11 includes two guide plates. Bolt 1 is conveyed between the two guide plates. The assembly track 11 has two guide wheels 12 that rotate through bearing seats. A transmission belt 13 is sleeved on the outer side of the two guide wheels 12 and is located between the guide plates. A motor 14 is fixedly installed on the assembly track 11. The output end of the motor 14 is fixedly connected to one of the guide wheels 12. When the motor 14 is actuated, the two guide wheels 12 are driven to rotate under the action of the transmission belt 13. The side of the transmission belt 13 away from the guide wheel 12 has protrusions formed at intervals. After the bolt 1 enters the assembly track 11 from the bolt track 8, the bolt 1 will contact the moving protrusion, so that the protrusion will push the bolt 1 to move in the assembly track 11. When the bolt 1 moves to a position that does not correspond to the transmission belt 13, the bolt 1 corresponding to the transmission belt 13 pushes the bolt 1 that does not correspond to the transmission belt 13.

[0016] like Figure 5 and Figure 6 As shown, baffles 15 are fixedly installed at the ends of the pad track 9 and the nut track 10 away from the vibratory feeder. The pad 2 and the nut 3 will slide from the pad track 9 and the nut track 10 to the corresponding baffles 15, respectively. The baffles 15 are formed with limiting grooves 16, and the limiting grooves 16 are consistent with the outer tangent circles of the pad 2 and the nut 3. In this way, when the pad 2 or the nut 3 corresponds to the limiting groove 16, the center of the pad 2 or the nut 3 is consistent with the center of the limiting groove 16, which can ensure the positional accuracy of the pad 2 or the nut 3.

[0017] like Figure 3 and Figure 7 As shown, a lifting turntable 17 is fixedly installed on the workbench 7. The lifting turntable 17 includes a base and a movable seat. The movable seat slides along the height of the base and can rotate around the base. The lifting turntable 17 is equipped with a picking component, which includes an electromagnet 19. The electromagnet 19 has a ring structure. A motor 18 is fixedly installed on the movable seat of the lifting turntable 17. A connecting plate 20 is installed on the output end of the motor 18. A guide rod 21 is fixedly installed on the electromagnet 19. The guide rod 21 passes through the connecting plate 20 and is equipped with a stop block. A spring 22 is sleeved on the guide rod 21. The two ends of the spring 22 are connected to the electromagnet 19 and the lifting turntable 17.

[0018] During the transfer process, the electromagnet 19 is moved by the lifting turntable 17, causing it to move above the baffle 15 connected to the nut track 10. Then, the lifting turntable 17 is activated, causing the electromagnet 19 to contact the nut 3 located in the limiting groove 16, energizing the electromagnet 19 and attracting it. The lifting turntable 17 is then activated again, moving the electromagnet 19 above the baffle 15 connected to the gasket track 9. The lifting turntable 17 is activated again, causing the nut 3 to contact the gasket 2 located in the limiting groove 16. The nut 3 is magnetized by contact with the electromagnet 19, attracting the gasket 2. The lifting turntable 17 is controlled to move the electromagnet away from the baffle 15, attracting both the nut 3 and the gasket 2. Thus, the nut 3 and the gasket 2 are removed, and the centers of the nut 3 and the gasket 2 are aligned with the center of the electromagnet 19. The limiting groove 16 is replenished with items by the vibrating plate.

[0019] like Figure 8 As shown, a cylinder 23 is fixedly installed on the workbench 7. A connecting seat 24 is fixedly installed on the piston end of the cylinder 23. A socket 25 is slidably installed on the connecting seat 24. A spring 26 is installed between the socket 25 and the connecting seat 24. The two ends of the spring 26 are connected to the connecting seat 24 and the socket 25 respectively. A rotating assembly is connected to the workbench 7. The rotating assembly includes a motor 32 and an electromagnet 30. The motor 32 is fixedly installed on the workbench 7. The electromagnet 30 is installed on the output end of the motor 32. During assembly, the motor 32 always drives the electromagnet 30 to rotate. When the bolt 1 moves a certain distance under the action of the protrusion, the motor 14 will be de-energized, so that the bolt 1 located on the assembly track 11 cannot move. At this time, one of the bolts 1 will correspond to the electromagnet 30.

[0020] When bolt 1 corresponds to electromagnet 2 30, electromagnet 2 30 is energized, attracting bolt 1 and causing it to rotate. At this time, cylinder 23 is activated, causing the insert block to press against the surface of bolt 1, and the connecting block and insert block to move relative to each other, causing spring 26 to deform. As bolt 1 rotates, the insert block remains pressed against the surface of bolt 1 due to the elasticity of spring 26. When the guide groove 4 of the bolt corresponds to the insert block, the insert block slides into the guide groove 4 due to the spring force, preventing electromagnet 2 30 from driving bolt 1 to rotate. By determining the position of guide groove 4, the eccentric position of bolt 1 is determined.

[0021] like Figure 8 and Figure 9As shown, the workbench 7 is equipped with a detection assembly, which includes a laser beam emitter 27 and a laser beam receiver 28. The laser beam emitter 27 is fixedly installed in the socket 25, and a transmission channel is formed inside the socket 25. One opening of the transmission channel faces the laser beam emitter 27, and the other opening of the transmission channel is located in the part of the socket 25 that enters the guide groove 4, away from the head of the bolt 1. A reflector 31 for reflecting the laser beam is fixedly installed in the side wall of the transmission channel. When the laser beam emitter 27 emits a beam, the beam will enter the transmission channel and irradiate the reflector 31. After being reflected by the reflector 31, the beam will be emitted through the other opening. The direction of the beam is consistent with the length direction of the screw, and the beam will be located in the guide groove 4. The laser beam receiver 28 is fixedly installed at the annular opening of the electromagnet 19.

[0022] After the nut 3 and washer 2 are removed, the lifting turntable 17 is activated, positioning the electromagnet 19 above the bolt 1. At this point, the laser beam will travel along the guide groove 4 towards the laser beam receiver 28. The motor 18 will then activate, causing the nut 3 and washer 2 to rotate. When the protrusion 6 of the washer 2 aligns with the guide groove 4, the protrusion 6 will block the laser beam, preventing the laser beam receiver 28 from receiving the beam. The motor 18 will then stop activating, stopping the rotation of the nut 3 and washer 2. Next, the lifting turntable 17 is activated, causing the nut 3 and washer 2 to move closer to the bolt 1. The bolt 1 is moved until its thread passes through the washer 2, and the threads of the nut 3 and the bolt thread abut against each other. The spring 22 is deformed by the force. Then, the motor 18 is activated, causing the bolt 1 and nut 3 to rotate relative to each other, so that the nut 3 and bolt 1 are connected, thus assembling the nut 3, bolt 1, and washer 2. After the assembly is completed, the electromagnets 19 and 30 are de-energized, and the lifting turntable 17 is reset, so that the bolt 1 that has been assembled is moved, so that the bolt 1 that has not been assembled corresponds to the electromagnet 30, thus allowing the assembly of the next bolt 1.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention.
