Description

Technical Field

[0001] This application relates to the field of motor processing technology, and in particular to a hot riveting machine for assembling end caps. Background Technology

[0002] The end cap assembly hot riveting machine is a special equipment for the press-fitting process of end caps and motor assemblies in the field of motor manufacturing. Its background technology stems from the limitations of the connection process between end caps and housings in the traditional motor assembly process. In the existing technology, the assembly of end caps and motor assemblies mostly relies on manual positioning and mechanical press-fitting equipment, which has problems such as low press-fitting accuracy, large coaxiality deviation, and insufficient assembly efficiency. In particular, when dealing with different motor models, the equipment parameters need to be frequently adjusted, resulting in poor production flexibility. Furthermore, traditional riveting processes such as mechanical stamping or welding are prone to stress concentration and brittle joints, making it difficult to meet the reliability requirements of motors under long-term vibration conditions. Hot riveting technology, by heating and softening plastic rivets before pressing, can achieve high-precision connections between end caps and motor housings, offering advantages such as good sealing and strong impact resistance. However, existing hot riveting equipment is mostly designed for single components, lacking integrated solutions for pressing motor end caps into the overall motor assembly. While some equipment uses hydraulic or pneumatic drives, it suffers from complex structures, high maintenance costs, and efficiency bottlenecks due to the separation of hot riveting and pressing processes.

[0015] Reference Appendix Figures 1-5 This is a schematic diagram of the overall structure of the end cap assembly hot riveting machine in one embodiment of this application; Example 1 A hot riveting machine for assembling end caps, wherein the end cap assembly is the assembly of the end cap and the assembly motor, comprising: Machine base 1, the top surface of which is a processing surface, and the end cover and the assembly motor are both transported and processed on the processing surface; End cap feeding assembly, the end cap feeding assembly includes a linear module 3, a material carrier 2 and a drive motor; The linear module 3 is disposed on the processing surface, the material carrier 2 is disposed on the linear module 3, the output end of the drive motor is connected to the material carrier 2, and the material carrier 2 with the end cap is driven by the drive motor to move linearly on the linear module 3; The assembly motor feeding assembly includes a speed-multiplying chain 6, a rotary fixture 7, and a self-rotating motor; the speed-multiplying chain 6 is disposed on the processing surface, the rotary fixture 7 is disposed on the speed-multiplying chain 6, and the self-rotating motor is disposed on the rotary fixture 7; the speed-multiplying chain 6 drives the rotary fixture 7 to move along the assembly motor. The end cap and assembly motor handling assembly picks up the end cap and assembly motor from the material carrier 2 and the rotating jig 7 respectively and transports them to other processing stations on the processing surface for processing. An end cap and motor assembly press-fit assembly is provided on the machining surface and presses the end cap and the motor assembly together. A hot riveting assembly 8 is disposed on the processing surface, and the hot riveting assembly 8 performs hot riveting treatment on the press-fitted finished product of the end cover and the assembly motor. The material cutting assembly cuts the hot-riveted end cap and the press-fitted motor assembly into the finished product.

[0016] In this embodiment, the end cap and assembly motor handling component is provided with a YZ handling module 4 and a double gripper 5; One end of the YZ transport module 4 is connected to the linear module 3, and the other end of the YZ transport module 4 is connected to the speed-multiplying chain 6. The double grippers 5 are disposed on the YZ transport module 4, and the double grippers 5 respectively grip the end caps on both sides of the YZ transport module 4 and the assembly motor.

[0017] The linear module 3 is parallel to the speed-multiplying chain 6, and the YZ transport module 4 is perpendicular to both the linear module 3 and the speed-multiplying chain 6.

[0018] Specifically, First, the end caps are loaded onto the material carrier 2, and up to six end caps can be loaded onto the material carrier 2 at the same time. The material carrier 2 moves on the linear module 3 under the drive of the drive motor to a position close to the YZ transport module 4. At the same time, the rotating fixture 7 on the double speed chain 6, carrying the assembly motor, gradually enters the processing surface. At this time, the double grippers 5 on the YZ transport module 4 will work simultaneously. One grips the end cap on the material carrier 2, and the other grips the assembly motor on the rotating fixture 7, and transports them to the middle of the YZ transport module 4 at the same time. The gripper 5 that carries the assembly motor is placed first on the end cap assembly position 11, and the gripper 5 that carries the assembly motor is placed last on the end cap assembly position 11, so that the assembly motor on the end cap assembly position 11 is below and the end cap is above. The end cap and the assembly motor are pressed together by the pressing assembly to form a pressed finished product. During the pressing process, a positioning mechanism 10 on the side will be used to position the outer wall of the assembly motor and to manage the copper wires on the assembly motor. The positioning and wire management operations before pressing can improve the success rate of pressing. After pressing is completed, the pressed product formed by the end cap and the assembly motor will be picked up by one of the double grippers 5 and placed on the rotating fixture 7 on the double speed chain 6. At this time, the rotating fixture 7 carrying the pressed product moves with the double speed chain 6 to the bottom of the hot riveting assembly 8. The hot riveting assembly 8 performs hot riveting work on the pressed product on the rotating fixture 7. After the hot riveting work, it enters the next station. In this embodiment, a rivet height detection component 9 is also included. The rivet height detection component 9 is disposed on the processing surface and located on the moving trajectory of the double-speed chain 6. The rivet height detection component 9 detects the rivet height of the hot-riveted end cap and the press-fitted finished product of the assembly motor.

[0019] Specifically, after being hot-riveted by the hot riveting assembly 8, the pressed finished product will move directly on the rotating fixture 7 along the speed-multiplying chain 6 into the area below the riveting height detection component 9 for riveting height detection. During the riveting height detection, the pressed finished product will be driven to rotate by the self-rotating motor under the rotating fixture 7, which facilitates the riveting height detection component 9 to perform all-round riveting height detection on the pressed finished product. If it passes the test, it will directly enter the next processing equipment; if it fails the test, it will be recycled into the defective product recycling component.
