Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, and in particular to a motor coil fixing and riveting equipment. Background Technology

[0002] During the production of motor housing, the magnetic pole coil needs to be fixed to the inner wall of the motor housing. The existing fixing method is to fix the magnetic pole coil to the inner wall of the motor housing using shims, bolts and magnetic pole holes on the motor housing. However, due to the complex working environment of the motor during use, the bolts fixing the magnetic pole will gradually loosen and fall off under the action of vibration, causing the magnetic pole coil to shift and causing motor failure. Utility Model Content

[0003] The technical problem to be solved by this utility model is that the bolt-fixed magnetic pole coil is prone to loosening and falling off under vibration.

[0004] To solve the above-mentioned technical problems, the present invention provides a technical solution: a motor coil fixing riveting device, including a fixing frame, a limiting device and a riveting device, characterized in that: the riveting device includes a riveting motor, a riveting head and a riveting fixing block, the riveting motor and the riveting head are arranged on the riveting fixing block and realize synchronous rotation of the two.

[0005] The limiting device includes a limiting post and support blocks. The four support blocks are disposed on the outside of the limiting post and are in contact with each other end to end. The four support blocks are driven by a driving mechanism to reciprocate along the radial direction of the limiting post.

[0006] The limiting post is vertically installed on one side of the fixed frame. Guide rails are provided on the fixed frames on opposite sides of the limiting post. The riveting fixing block is installed on the guide rail and moves back and forth along the guide rail by the moving mechanism. The riveting head is located at the end close to the limiting post.

[0007] Furthermore, the moving mechanism includes an electric screw and a slider. The electric screw is mounted on the fixed frame, and the slider is screwed to the electric screw and slidably mounted on the guide rail. The riveting fixing block is mounted on the slider.

[0008] Furthermore, the limiting post is rotatably mounted on the fixed frame via a reversing motor.

[0009] Furthermore, the driving mechanism includes a driving cylinder, a guide rod, and an annular elastic band. The limiting post has a cylindrical structure. The driving cylinder is located on the other side of the fixed frame. The guide rod passes through the limiting post, the reversing motor, and the fixed frame, and is linked with the driving cylinder to realize the reciprocating movement of the guide rod up and down. The side wall of the limiting post is provided with four guide holes. The guide block on the support block extends from the outside to the inside of the limiting post through the guide holes and contacts the guide rod. The tapered section on the guide rod pushes the guide block and the support block to move outward. The annular elastic band is sleeved on the outside of the support block to realize the inward movement of the guide block and the support block.

[0010] Furthermore, the support block is provided with an annular groove into which an annular elastic band is embedded.

[0011] Furthermore, a limiting plate is provided at the top of the limiting post, and radially arranged sliding grooves are provided at the bottom of the limiting post and on the limiting plate. Protrusions extending into the sliding grooves are provided at the bottom and top of the support block.

[0012] Furthermore, the tapered section on the guide rod is coaxially rotatably connected to the guide rod near the drive cylinder.

[0013] Furthermore, the top of the guide block is beveled.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This application utilizes the cooperation between a fixed frame, a limiting device, and a riveting device. The two riveting devices clamp the limiting device, and when the riveting device moves toward the limiting device, it performs riveting on the motor magnetic pole hole fitted on the limiting device, thereby achieving the riveting connection between the magnetic pole coil and the motor housing, solving the problem of bolt connections easily loosening and falling off.

[0016] 2. In this application, the electric screw and the slider are used together. The forward and reverse rotation of the electric screw enables the riveting head to move closer to and away from the motor housing. At the same time, the electric screw uses a stepper motor to control the movement distance of the riveting head and also has a self-locking function to ensure the riveting quality.

[0017] 3. In this application, the limiting post is rotatably mounted on the fixed frame by a reversing motor. Since the two riveting devices clamp the limiting device, the two opposite magnetic pole coils can be riveted and connected at the same time, which improves the working efficiency. Under the drive of the reversing motor, the limiting device and the motor housing can rotate 90 degrees, which facilitates the riveting and connection of the remaining two magnetic pole coils. The operation is convenient and further improves the working efficiency.

[0018] 4. In this application, the drive cylinder drives the guide rod to move up and down reciprocally. The guide block contacts the guide rod under the action of the annular elastic band, and pushes the guide block and support block outward along the guide hole under the action of the tapered section on the guide rod, pressing the gasket and magnetic pole coil against the inner wall of the motor housing, which facilitates subsequent riveting operations and ensures the quality of riveting. After riveting is completed, the drive cylinder drives the guide rod to reset, and the guide block and support block reset under the action of the annular elastic band, releasing the pressure on the gasket and magnetic pole coil, making it easy to remove the motor housing. The tapered section on the guide rod is coaxially rotatably connected to the guide rod near the drive cylinder, so that the limiting end can move up and down under the action of the drive cylinder and can also rotate axially. When the reversing motor drives the limiting post and the motor housing as a whole to move, the tapered section rotates together.

[0019] 5. In this application, the support block is provided with an annular groove into which an annular elastic band is embedded, which protects the annular elastic band and facilitates contact between the support block and the gasket and magnetic pole coil, ensuring the stability of the clamping.

[0020] 6. In this application, the limiting plate is set at the top of the limiting column, and the protrusions at the bottom and top of the support block extend into the slide groove and can move within the slide groove, which guides the movement of the support block and ensures smooth movement.

[0021] 7. In this application, the top of the guide block is beveled, which facilitates matching and sliding with the tapered section on the guide rod, and makes it easy for the guide block to move outward along the guide hole under the push of the tapered section.

[0031] The names of the messages or information exchanged between the multiple devices in this embodiment of the invention are for illustrative purposes only and are not intended to limit the scope of these messages or information. Example 1

[0032] like Figure 1-4 As shown, a motor coil fixing riveting device includes a fixing frame 1, a limiting device, and a riveting device. The riveting device includes a riveting motor 2, a riveting head 3, and a riveting fixing block 4. The riveting motor 2 and the riveting head 3 are mounted on the riveting fixing block 4 and rotate synchronously. The limiting device includes a limiting post 5 and four support blocks 6. The four support blocks 6 are mounted on the outside of the limiting post 5 and are in contact with each other end to end. The four support blocks 6 are driven by a driving mechanism to reciprocate along the radial direction of the limiting post 5. The limiting post 5 is vertically mounted on one side of the fixing frame 1. Guide rails 7 are mounted on the fixing frame 1 on both sides of the limiting post 5. The riveting fixing block 4 is mounted on the guide rails 7 and reciprocates along the guide rails 7 by a moving mechanism. The riveting head 3 is located at the end close to the limiting post 5.

[0033] The moving mechanism includes an electric screw 8 and a slider 9. The electric screw 8 is mounted on the fixed frame 1, and the slider 9 is screwed to the electric screw 8 and slidably mounted on the guide rail 7. The riveting fixing block 4 is mounted on the slider 9. The two riveting devices clamp the limiting device. When the riveting devices move toward the limiting device, they rivet the motor magnetic pole hole fitted on the limiting device, thus achieving the riveting connection between the magnetic pole coil B and the motor housing A. The electric screw 8 and the slider 9 work together. The forward and reverse rotation of the electric screw 8 moves the riveting head 3 closer to the motor housing A and away from the motor housing A. At the same time, the electric screw 8 uses a stepper motor to control the movement distance of the riveting head 3 and also has a self-locking function to ensure the riveting quality.

[0034] The limiting post 5 is rotatably mounted on the fixed frame 1 via the reversing motor 10, which is an external rotor motor. The limiting post 5 is rotatably mounted on the fixed frame 1 via the reversing motor 10. Since the two riveting devices clamp the limiting device, they can simultaneously rivet the two opposite magnetic pole coils B, improving work efficiency. Under the drive of the reversing motor 10, the limiting device and the motor housing A can rotate 90 degrees, which facilitates the riveting connection of the remaining two magnetic pole coils B. The operation is convenient and further improves work efficiency.

[0035] The driving mechanism includes a driving cylinder 11, a guide rod 12, and an annular elastic band 13. The limiting post 5 has a cylindrical structure. The driving cylinder 11 is located on the other side of the fixed frame 1. The guide rod 12 passes through the limiting post 5, the reversing motor 10, and the fixed frame 1, and is linked with the driving cylinder 11 to realize the reciprocating movement of the guide rod 12. The side wall of the limiting post 5 is provided with four guide holes 14. The guide block 15 on the support block 6 extends from the outside to the inside of the limiting post 5 through the guide holes 14 and contacts the guide rod 12. The tapered section 16 on the guide rod 12 pushes the guide block 15 and the support block 6 to move outward. The annular elastic band 13 is sleeved on the outside of the support block 6 to realize the inward movement of the guide block 15 and the support block 6. The driving cylinder 11 drives the guide rod 12 to move up and down reciprocally. The guide block 15 contacts the guide rod 12 under the action of the annular elastic band 13, and... Under the action of the tapered section 16 on the guide rod 12, the guide block 15 and the support block 6 are pushed outward along the guide hole 14, pressing the shim C and the magnetic pole coil B against the inner wall of the motor housing A, which facilitates the subsequent riveting operation and ensures the quality of riveting. After the riveting is completed, the drive cylinder 11 drives the guide rod 12 to reset, and the guide block 15 and the support block 6 are reset under the action of the annular elastic band 13, releasing the pressure on the shim C and the magnetic pole coil B, making it easy for the motor housing A to remove the tapered section 16 on the guide rod 12 and connect it coaxially with the guide rod 12 near the drive cylinder 11 (it can be connected through a rotary joint), so that the limiting end can move up and down under the action of the drive cylinder 11 and can also rotate axially. When the reversing motor 10 drives the limiting post 5 and the motor housing A to move as a whole, the tapered section 16 rotates together. Example 2

[0036] like Figure 1-4 As shown, this embodiment is obtained by adding technical features such as an annular groove 17 on the basis of embodiment one. The other technical features are the same as those in embodiment one. The similarities will not be repeated here. The difference between this embodiment and embodiment one is that the support block 6 is provided with an annular groove 17 into which an annular elastic band 13 is embedded.

[0037] In this embodiment, the support block 6 is provided with an annular groove 17 into which the annular elastic band 13 is embedded, which protects the annular elastic band 13 and facilitates contact between the support block 6 and the gasket C and the magnetic pole coil B, ensuring the stability of the clamping. Example 3

[0038] like Figure 1-4As shown, this embodiment is obtained by adding technical features such as the sliding groove 19 and the protrusion 20 on the basis of embodiment two. The remaining technical features are the same as those in embodiment two, and the similarities will not be repeated here. The difference between this embodiment and embodiment two is that: the top of the limiting post 5 is provided with a limiting plate 18, the bottom of the limiting post 5 and the limiting plate 18 are provided with radially arranged sliding grooves 19, the bottom and top of the support block 6 are provided with protrusions 20 extending into the sliding grooves 19; the top of the guide block 15 is beveled.

[0039] In this embodiment, the limiting plate 18 is set on the top of the limiting post 5, and the protrusions 20 at the bottom and top of the support block 6 extend into the slide groove 19 and can move within the slide groove 19, which guides the movement of the support block 6 and ensures smooth movement; the top of the guide block 15 is beveled, which facilitates matching and sliding with the tapered section 16 on the guide rod 12, and facilitates the guide block 15 to move outward along the guide hole 14 under the push of the tapered section 16.

[0040] The process of using the overall technical solution formed by the above embodiments is as follows: The motor housing A, equipped with rivets, gaskets C, and magnetic pole coils B, is fitted onto the limiting post 5 (the rivets replace bolts for installation). The drive cylinder 11 drives the guide rod 12 to move downwards, and the tapered section 16 pushes the guide block 15 to move outwards along the guide hole 14, pressing the gasket C and the magnetic pole coil against the inner wall of the motor housing A. At this time, the annular elastic band 13 undergoes energy storage elastic deformation, and the electric screw 8 pushes the slider 9 and the riveting head 3 to move towards the motor housing A. The riveting motor 2 drives the riveting head 3 to rotate, and the riveting head 3 rotates into contact with one end of the rivet. The other end of the rivet is limited by the support block 6, completing the two opposing magnetic pole lines. In the riveting connection of coil B, after the riveting head 3 is reset under the action of the electric screw 8, the rotary motor drives the limit post 5 and the motor coil to rotate 90 degrees together. The electric screw 8 then pushes the slider 9 and the riveting head 3 to move towards the motor housing A, completing the riveting connection of the remaining two opposing magnetic pole coils B. After the riveting head 3 is reset again under the action of the electric screw 8, the rotary motor drives the limit post 5 and the motor coil to rotate 90 degrees in the opposite direction to reset. The drive cylinder 11 drives the guide rod 12 to move upward, the tapered section 16 releases the thrust on the guide block 15, and the support block 6 and the guide block 15 are reset under the action of the annular elastic band 13, completing the riveting connection of the magnetic pole coils B on the motor housing A.
