Abstract
Description
Technical Field
[0001] This application relates to the technical field of winding iron core production, and in particular to a riveting device for processing winding iron cores of motor stators. Background Technology
[0002] The winding process has good processability, produces no shearing waste, and has a utilization rate of almost 100%. It can also be mechanized, eliminating the stacking process and increasing production efficiency by 5-10 times compared to stacked cores.
[0003] After stamping, the wound iron core needs to be fixed with rivets. In the existing technology, the rivets are usually installed manually and then hammered one by one with a small hammer. Manual hammering is inefficient and prone to misalignment, which can damage the iron core. At the same time, the hammering force of each rivet is inconsistent, which affects the product qualification rate.
[0004] Therefore, there is an urgent need to develop a semi-automatic riveting device to improve production efficiency. Utility Model Content
[0005] The purpose of this application is to provide a riveting device for machining the stator winding core of an electric motor, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this application provides a riveting device for machining the stator winding core of an electric motor, employing the following technical solution:
[0007] A riveting device for processing the winding core of a motor stator includes a worktable, a positioning mold, a slide block, a frame, and a riveting press. The worktable surface is symmetrically fixed with slide rails. There are two slide blocks, which are slidably connected to the slide rails. A pusher cylinder is fixed to one side of each slide block, and the pusher cylinder is used to drive the slide block to move along the slide rail. The frame is located in the middle of the worktable, and the riveting press is fixed to the bottom of the frame. The positioning mold is fixed on the slide block.
[0008] The positioning mold includes a base, the surface of which has an annular groove, and a plurality of positioning protrusions are evenly arranged in the annular groove. The positioning protrusions are adapted to the grooves on the surface of the wound iron core.
[0009] Preferably, the frame is further provided with a feeding mechanism, which includes a Y-axis moving module, an X-axis servo linear guide slide, a Z-axis lifting cylinder, and a pneumatic three-jaw chuck. The Y-axis moving module is installed on the side of the frame, the X-axis servo linear guide slide is installed on the Y-axis moving module, the Z-axis lifting cylinder is installed on the slide of the X-axis servo linear guide slide, the piston rod end of the Z-axis lifting cylinder is fixed with a mounting bracket, and the pneumatic three-jaw chuck is fixed to the bottom of the mounting bracket.
[0010] By adopting the above technical solution and setting up a feeding mechanism, after riveting, the Y-axis moving module and the X-axis servo linear guide slide drive the Z-axis lifting cylinder to move to the top of the stator winding core. The Z-axis lifting cylinder drives the pneumatic three-jaw chuck to move downward. After the pneumatic three-jaw chuck supports the stator winding core tightly from the inner wall, the Z-axis lifting cylinder, the X-axis servo linear guide slide, and the Y-axis moving module cooperate to remove the stator winding core for feeding. No manual feeding is required. After the slide is reset, the operator can hold the pre-organized winding core and place it directly on the positioning mold, thereby improving work efficiency.
[0011] The pneumatic three-jaw chuck can be wound around the inner wall of the motor stator to hold it tight.
[0012] Preferably, in order to facilitate the placement of the wound iron core, the top of the positioning protrusion is an arc surface, and the top edge of the annular groove is arc-shaped.
[0013] In summary, this application includes at least one of the following beneficial technical effects: the riveting device for processing the stator winding core of the motor utilizes a riveting machine, resulting in more uniform force on each rivet, preventing accidental damage to the winding core body, and achieving a higher product qualification rate; simultaneously, by setting two slides, two loading stations are formed. When one slide enters the riveting machine for riveting, the workers on that side can prepare and hold the winding core in advance for placement, while the workers on the other side are placing the winding core. The two loading stations work together to achieve continuous riveting by the riveting machine, thereby improving production efficiency. Attached Figure Description

Detailed Implementation
[0018] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0019] This application discloses a riveting device for machining the stator winding core of an electric motor, referring to... Figure 1-3 The machine includes a worktable 1, a positioning mold 3, a slide block 2, a frame 4, and a riveting machine 5. The worktable 1 has symmetrically fixed slide rails on its surface. There are two slide blocks 2, which are slidably connected to the slide rails. A pusher cylinder 6 is fixed on one side of the slide block 2. The pusher cylinder 6 is used to drive the slide block 2 to move along the slide rail. The frame 4 is located in the middle of the worktable 1. The riveting machine 5 is fixed at the bottom of the frame 4. The positioning mold 3 is fixed on the slide block 2. The positioning mold 3 includes a base 31. The surface of the base 31 has an annular groove 32. Multiple positioning protrusions 321 are evenly arranged in the annular groove 32. The positioning protrusions 321 are adapted to the grooves on the surface of the wound iron core.
[0020] Specific reference Figure 3 To better position the wound iron core, the top of the positioning protrusion 321 is an arc surface, and the top edge of the annular groove 32 is arc-shaped.
[0021] Reference Figure 1-2 The frame 4 is also equipped with a feeding mechanism, which includes a Y-axis moving module 7, an X-axis servo linear guide slide 8, a Z-axis lifting cylinder 9, and a pneumatic three-jaw chuck 911. The Y-axis moving module 7 is installed on the side of the frame 4, the X-axis servo linear guide slide 8 is installed on the Y-axis moving module 7, the Z-axis lifting cylinder 9 is installed on the slide of the X-axis servo linear guide slide 8, the piston rod end of the Z-axis lifting cylinder 9 is fixed with a mounting bracket 91, and the pneumatic three-jaw chuck 911 is fixed at the bottom of the mounting bracket 91. The pneumatic three-jaw chuck 911 can be wound around the inner wall of the iron core from the motor stator to support it tightly.
[0022] With the feeding mechanism in place, after riveting is completed, the Y-axis moving module 7 and the X-axis servo linear guide slide 8 drive the Z-axis lifting cylinder 9 to the top of the stator winding core. The Z-axis lifting cylinder 9 drives the pneumatic three-jaw chuck 911 to move downwards. After the pneumatic three-jaw chuck 911 supports the stator winding core tightly from the inner wall, the Z-axis lifting cylinder 9, the X-axis servo linear guide slide 8 and the Y-axis moving module 7 work together to remove the stator winding core and feed it out. No manual feeding is required. After the slide 2 is reset, the staff can hold the prepared winding core in advance and place it directly on the positioning mold 3, thereby improving work efficiency.
[0023] The implementation principle of the riveting device for machining the stator winding core of a motor according to an embodiment of this application is as follows:
[0024] By setting up two slides 2, two feeding stations are formed. When one slide 2 enters the riveting machine 5 for riveting work, the workers on this side can prepare and hold the coiled iron core in advance for placement. At the same time, the workers on the other side are placing the coiled iron core and inserting rivets. The two feeding stations work together to realize continuous riveting of the riveting machine 5, thereby improving production efficiency.
[0025] When placing the wound iron core, the staff only needs to align the groove on the surface of the wound iron core with the positioning protrusion 321 and insert it, and then put the rivets into the rivet holes on the surface of the wound iron core one by one.
[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
