Description

Technical Field

[0001] This utility model relates to the field of automotive motor assembly technology, and in particular to an automotive motor lead screw riveting device. Background Technology

[0002] In the automated assembly line of automotive motors, the riveting and assembly of the lead screw with related components is a key process. This process usually requires precise alignment of the lead screw with another component and completion of the riveting by stamping. In order to achieve automation, a robotic arm solution based on pneumatic grippers and stepper motors is commonly used.

[0003] The existing technical solutions have the following drawbacks: The existing technology uses a pneumatic gripper and a stepper motor robotic arm solution. Since this solution uses three robotic arms to work in sequence, each action requires separate start-up, operation, stop and waiting time, resulting in a long production cycle and the need for repeated positioning, which leads to the accumulation of errors and affects the production quality of the product. Utility Model Content

[0004] The purpose of this invention is to provide an automotive motor lead screw riveting device to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A lead screw riveting device for an automotive motor includes a frame, characterized in that: an automatic feeding mechanism is fixedly installed on the right side of the frame, the automatic feeding mechanism being used to lift the lead screw material to a receiving area; a receiving mechanism is provided at the top right end of the frame, the receiving mechanism being connected to the top left end of the automatic feeding mechanism, the receiving mechanism being used to receive the lead screw material; a first rectangular hole is provided at the middle position of the top of the frame, the first rectangular hole containing a rotating disk assembly, the rotating disk assembly being used for conveying and positioning the lead screw material; and a movable disk module is fixedly installed at the top left end of the frame, the movable disk module being connected to the rotating disk assembly. The moving plate module is used to sort and convey the lead screw head material to the riveting position of the riveting module. The riveting module is fixedly installed on the top of the moving plate module. The riveting module is used to precisely rivet the lead screw and lead screw head. Two deburring clamping and rotating mechanisms are provided in the frame. The deburring clamping and rotating mechanisms are used to grind and deburr the riveting area. The deburring clamping and rotating mechanisms are fixedly installed at the bottom of the moving plate module and at the bottom of the rotating plate assembly. The same discharge mechanism is fixedly installed at the bottom of the deburring clamping and rotating mechanisms. The discharge mechanism is used to collect the processed workpiece.

[0007] By adopting the above technical solutions, the automatic feeding structure, rotary disk assembly, moving disk module, riveting module, deburring clamping and rotating mechanism, and discharge mechanism form a circular automated production line, which solves the problems of slow transmission speed and low production efficiency, while also avoiding the problem of repeated positioning and improving product quality.

[0008] In a further embodiment, the rotary disk assembly includes a speed reducer, which is fixedly mounted on the top of the frame. A motor is fixedly mounted on the right side of the speed reducer, and a rotary disk is rotatably mounted on the front side of the speed reducer. The rotary disk is located in a first rectangular hole, and multiple claws are axially and uniformly fixedly mounted on the front end face of the rotary disk.

[0009] By adopting the above technical solution, the entire processing is completed around the same rotation center. The positioning reference of the workpiece is always the gripper on the rotary table. It is only necessary to ensure that the relative position of each fixed station to the rotation center is accurate, thus avoiding the accumulation of errors.

[0010] In a further embodiment, the moving plate module includes a base plate, which is fixedly installed on the top left end of the frame. A stamping base is fixedly installed on the top rear end of the base plate. A receiving groove is provided on the top of the stamping base.

[0011] By adopting the above technical solution, the stamping head can slide up and down within the receiving groove, using the elasticity of the spring to buffer and protect the workpiece, while ensuring the stability and precision of the stamping process. A vibratory feeder is fixedly installed on the left side of the base plate, and a conveyor belt is connected to the right side of the vibratory feeder. The conveyor belt smoothly transports the sorted lead screw head material to the riveting position on the stamping base, ensuring the continuity and accuracy of material transfer.

[0012] In a further embodiment, the riveting module includes support rods, with support rods fixedly installed at each of the four corners of the base plate. A mounting plate is fixedly installed on the top of each support rod, and a cylinder is fixedly installed at the bottom rear end of the mounting plate.

Linear bearing seats are slidably installed on the sliding rods, and the linear bearing seats are fixedly installed to the riveting plate. The top center of the riveting plate is fixedly installed to the bottom end of the cylinder.

[0013] By adopting the above technical solution, the cylinder drives the riveting plate to move up and down along the slide bar. The guiding effect of the linear bearing seat ensures the stability and accuracy of the riveting process. During the pressing process, the riveting plate cooperates with the punch head to complete the precision riveting of the lead screw and the lead screw head.

[0014] In a further embodiment, a scrap metal collection box is fixedly installed at the bottom of the deburring gripping and rotating mechanism, the scrap metal collection box being used to collect the scrap metal generated during deburring.

[0015] By adopting the above technical solution, the generated iron filings can be recycled and processed in a unified manner without polluting the environment, and the working environment can be kept clean.

[0016] In a further embodiment, a baffle is fixedly installed on the rear side of the receiving mechanism, and the baffle is used for positioning the lead screw.

[0017] By adopting the above technical solution, the baffle can effectively prevent the lead screw from deviating, fix the position of the jaw clamp on the lead screw, and ensure that it accurately enters the subsequent processing stage.

[0018] In a further embodiment, foot cups are fixedly installed at the four bottom corners of the frame.

[0019] By adopting the above technical solution, the design of the foot cup enables the device to adapt to various working environments and avoid equipment tilting or vibration caused by uneven ground.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. By setting up the riveting module, it is possible to precisely rivet the lead screw conveyed by the rotating disk and the lead screw head conveyed by the moving disk module;

Next, the moving plate module 5 is used to sort and convey the lead screw head material to the riveting position of the riveting module 6. The riveting module 6 is fixedly installed on the top of the moving plate module 5. The riveting module 6 is used to precisely rivet the lead screw and the lead screw head. Two deburring clamping and rotating mechanisms 7 are provided in the frame 1. The deburring clamping and rotating mechanisms 7 are used to grind and deburr the riveting area. The deburring clamping and rotating mechanisms 7 are fixedly installed at the bottom of the moving plate module 5. The deburring clamping and rotating mechanisms 7 are fixedly installed at the bottom of the rotating plate assembly 4. The same discharge mechanism 8 is fixedly installed at the bottom of the deburring clamping and rotating mechanisms 7. The discharge mechanism 8 is used to collect the processed workpiece.

[0032] The rotary disk assembly 4 includes a speed reducer 9, which is fixedly installed on the top of the frame 1. A motor 10 is fixedly installed on the right side of the speed reducer 9. A rotary disk 11 is rotatably installed on the front side of the speed reducer 9. The rotary disk 11 is located in the first rectangular hole. Multiple claws 12 are axially and evenly fixedly installed on the front end face of the rotary disk 11.

[0033] The moving plate module 5 includes a base plate 13, which is fixedly installed on the top left end of the frame 1. A stamping base 14 is fixedly installed on the top rear end of the base plate 13. A receiving groove is provided on the top of the stamping base 14. Springs are symmetrically fixedly installed on the bottom of the receiving groove. A stamping head 15 is slidably installed in the receiving groove. A vibrating plate 16 is fixedly installed on the left side of the base plate 13. A conveyor belt is fixedly installed on the right side of the vibrating plate 16. The conveyor belt is connected to the stamping base 14.

[0034] The riveting module 6 includes support rods 17. Support rods 17 are fixedly installed at the four corners of the base plate 13. The same mounting plate 18 is fixedly installed on the top of the support rods 17. Multiple sliding rods 19 are provided at the bottom of the mounting plate 18. The bottom end of the sliding rods 19 is fixedly installed with the stamping base 14. A linear bearing seat 20 is slidably installed on the sliding rod 19. The linear bearing seat 20 is fixedly installed with the riveting plate 21. A cylinder 22 is fixedly installed at the rear end of the bottom of the mounting plate 18. The top center of the riveting plate 21 is fixedly installed with the bottom end of the cylinder 22.

[0035] A scrap metal collection box 23 is fixedly installed at the bottom of the deburring and gripping rotating mechanism 7. The scrap metal collection box 23 is used to collect the scrap metal generated during deburring.

[0037] Specific implementation process: The lead screw material to be processed is placed in the automatic feeding mechanism 2. The automatic feeding mechanism 2 transports the lead screw material to the receiving mechanism 3. The receiving mechanism 3 pushes the lead screw material to fit against the baffle 24. The reducer 9 and motor 10 are started to drive the rotating disk 11 to rotate at a constant speed. The grippers 12 of the rotating disk 11 also rotate at a constant speed. When the grippers 12 rotate to the receiving mechanism 3, the lead screw material is picked up by the grippers 12 and rotates at a constant speed. When it approaches the riveting module 6, the rotation speed of the rotating disk 11 decreases, and the lead screw material is sent to the stamping base 14. At this time, the lead screw head material in the vibrating disk 16 is transported to the designated position by the conveyor belt. When the materials arrive at the designated position, the cylinder 22 of the riveting module 6 pushes the hydraulic rod downward, which in turn drives the riveting plate 21 downward. Under the thrust of the cylinder 22, the riveting plate 21 squeezes the punch head 15 downward, thus completing the riveting of the lead screw and the lead screw head. After the riveting is completed, the claw 12 will bring the material into the deburring station. The deburring gripping rotating mechanism 7 will brush away the burrs. The iron filings generated during deburring will fall into the iron filings recycling box. After the burrs are removed, the material will be sent into the discharge mechanism 8. Since there are multiple claws 12 on the rotating disk 11, the next round of work will continue after one claw 12 has finished.
