[0002] During the motor production process, the applicant manually installed the excitation winding on the motor housing through gaskets and bolts, and then held the excitation winding with one hand and tightened the bolts with an electric screwdriver with the other hand to fix the excitation winding on the motor housing. Since there are generally multiple excitation windings in the motor, they need to be manually installed one by one, which increases the labor intensity of the personnel and has low production efficiency. The installed motor coil is then manually transferred to the resistance detection station for insulation testing. During this process, personnel are also required to repeatedly take the motor housing for insulation testing operations. It can be seen that the above-mentioned processes are independent of each other and rely on manual transportation, which has low production efficiency. Moreover, the bolts realize the fixed connection between the excitation winding and the motor housing. Due to the complex working environment of the motor during use, the bolts fixing the excitation winding will gradually loosen and fall off under the action of vibration, resulting in the displacement of the excitation winding and causing motor failure.

[0013] Furthermore, the insulating bracket includes an insulating frame and an insulating cylinder, one side of the insulating frame is provided with four protrusions, and the other side of the insulating frame is connected to the vertically arranged insulating cylinder.

[0014] The beneficial effects of the present invention are: 1. The present application connects the assembly table, rolling and riveting equipment, testing equipment and finished product table through a conveyor belt, and realizes the transfer of the motor casing between various workstations through the transfer equipment, realizes automatic rolling and riveting and testing operations on the motor casing, realizes automated production operations, and improves work efficiency. At the same time, the excitation coil and the motor casing are changed from bolt connection to riveting, which increases the connection strength between the two, reduces the problem of looseness during use, and increases product quality.

[0015] 2. In the present application, a conveying track and a return track with opposite rotation directions are laid correspondingly up and down through the bracket, and the pallet is transferred on the conveying track and the return track through a conversion device arranged at the end, and the reversing of the pallet moving device is realized, so that the pallet can automatically return from the finished product table to the assembly table, without the need for personnel to transfer, thereby reducing labor intensity. The conveying position sensor is used to detect whether a motor housing has arrived, and then the conveying limit block is used to limit the pallet with the motor housing placed on it, so that it stops moving with the conveying track, which is convenient for clamping, transferring and detecting the motor housing.

[0016] 3. In the present application, the conversion hook hooks the pallet at the tail of the conveying track, and then the conversion push-pull cylinder drives the conversion push-pull plate and the conversion hook to move, and drives the pallet to move to the conversion lifting frame together, and then drives the conversion push-pull cylinder and the pallet to move up and down through the conversion lifting cylinder. When the pallet moves to the head of the return track, the conversion push-pull cylinder drives the conversion push-pull plate and the pallet to move toward the head of the return track together. When the pallet moves to the head of the return track, the conversion hook releases the hooking of the pallet, and the pallet moves driven by the return track, thereby completing the reversal of the pallet movement and realizing the reversal automation; the conversion hook is L-shaped, and the corner of the conversion hook is hinged to the conversion push-pull plate downward, so when the conversion hanging cylinder is actuated, the hanging end of the conversion hook rotates up and down around the corner of the conversion hook, and the conversion hook cooperates with the protrusion at the bottom of the pallet to realize the conversion hook to hang the pallet, thereby realizing automated production.

[0017] 4. In the present application, the rolling rivet limit column is rotated by the rolling rivet reversing motor and is set on the rolling rivet fixing frame. Since the two rolling rivet heads clamp the rolling rivet limit column, when the rolling rivet head moves toward the rolling rivet limit column, the rivet at the motor pole hole on the rolling rivet limit column is rolled and riveted, thereby realizing the rolling and riveting connection between the pole coil and the motor casing, solving the problem that the bolt connection is easy to loosen and fall off, and the rolling rivet limit column and the motor casing are rotated 90 degrees under the drive of the rolling rivet reversing motor, which is convenient for rolling and riveting the remaining two pole coils, and the operation is convenient.

[0018] 5. In the present application, the rolling rivet driving cylinder drives the rolling rivet guide rod to move reciprocatingly up and down, and the rolling rivet guide block contacts the rolling rivet guide rod under the action of the rolling rivet annular elastic band, and pushes the rolling rivet guide block and the rolling rivet support block to move outward along the rolling rivet guide hole under the action of the conical section on the rolling rivet guide rod, so that the gasket and the magnetic pole coil are pressed against the inner wall of the motor casing, which is convenient for subsequent rolling rivet operations and ensures the quality of rolling rivets. After the rolling rivet is completed, the rolling rivet driving cylinder drives the rolling rivet guide rod to reset, and the rolling rivet guide block and the rolling rivet support block are reset under the action of the rolling rivet annular elastic band, releasing the gasket and magnetic pole coil. The pole coil is tightened to facilitate the removal of the motor casing; the conical section on the rolling rivet guide rod is coaxially connected to the rolling rivet guide rod near the rolling rivet driving cylinder, so that the limit end can move up and down under the action of the rolling rivet driving cylinder, and can also rotate axially. When the rolling rivet reversing motor drives the rolling rivet limit column and the motor casing to move as a whole, the conical section can rotate together; the rolling rivet support block is provided with a rolling rivet annular groove in which the rolling rivet annular elastic band is embedded, which protects the rolling rivet annular elastic band and facilitates the contact between the rolling rivet support block, the gasket and the magnetic pole coil to ensure the tightening stability.

[0019] 6. In the present application, the transfer drive slider realizes movement in the horizontal space by driving the movement of the motor on the transfer track frame, realizes movement in the vertical direction by the extension and retraction of the transfer telescopic motor, realizes the tightening and loosening of the motor casing by the transfer clamp motor to perform gripping operation, and realizes the transfer of the motor casing between the assembly table, the conveying track, the rolling and riveting equipment and the finished product table. At the same time, when the motor casing is placed on the rolling and riveting limit column in the rolling and riveting equipment, the motor casing is sleeved on the rolling and riveting limit column, and the fixed top core is pushed out of the motor casing. After the motor casing is placed, the transfer clamp motor continues to move downward, and the fixed top core is taken out of the motor casing by using the inner clamp on the transfer clamp motor. No manual participation is required in the whole process, and mechanized operation is convenient for assembly line work, saving working time and improving work efficiency.

[0020] 7. In the present application, the fixed top core is placed in the motor casing where the excitation coil needs to be installed. When placed, each installation groove corresponds to the outer rivet hole on the motor casing for fixing the excitation coil. At this time, all the excitation coils are placed in the predetermined position, and a gasket with a rivet is placed in the installation groove so that the outer rivet hole and the rivet are fixed on the same straight line. The rivet is inserted into the outer rivet hole, which is convenient for later use of the rivet setting to rivet the rivet to fix the excitation coil in the motor casing. There is no need to manually hold the excitation coil, and the required excitation coil can be confined in the motor casing at one time, saving time and effort, saving labor, and improving production efficiency.

[0021] 8. In the present application, the inclined slide connects the rolling and riveting equipment with the assembly table. Since the height of the rolling and riveting equipment end of the inclined slide is higher than the assembly table end of the inclined slide, when the fixed top core is placed in the inclined slide at the rolling and riveting equipment by the transfer clamp motor, the fixed top core automatically slides from the rolling and riveting equipment to the assembly table under the action of gravity, thereby realizing automatic transfer of the fixed top core without the need for personnel to transfer, thereby improving work efficiency and reducing labor intensity. The rolling and riveting equipment end of the inclined slide is provided with a funnel-shaped placement opening to facilitate placing the fixed top core in the inclined slide.

[0022] 9. In the present application, the insulating bracket is arranged between the two guide rails in the conveying track, and the tray is lifted up from the conveyor belt to break away from the contact with the conveying track, so that the positive probe and the negative probe are respectively connected to the positive and negative poles of the resistance tester, so that the resistance test circuit is turned on and the resistance test is completed. Since the insulating bracket is made of insulating material, the stability of the resistance measurement is guaranteed. Since the positive probe and the negative probe are above the motor housing, the movement of the motor housing is not affected.

[0023] 10. In the present application, the insulating cylinder is vertically arranged so that the insulating bracket drives the insulating frame to move up and down. The protrusion on the insulating bracket increases the height of the tray and reduces the production cost of the insulating bracket. The insulating bracket is made of insulating material to ensure the accuracy of the detection.

Embodiment 6

[0060] This embodiment is obtained by further describing technical features such as the insulating bracket on the basis of the fifth embodiment. The remaining technical features are the same as those of the fifth embodiment, and the similarities are not repeated here. Among them, the difference between this embodiment and the fifth embodiment is that the insulating bracket includes an insulating frame 303 and an insulating cylinder 304, four protrusions are arranged on one side of the insulating frame 303, and the other side of the insulating frame 303 is connected to the vertically arranged insulating cylinder 304.

[0061] In this embodiment, the insulating cylinder 304 is vertically arranged to enable the insulating bracket to drive the insulating frame 303 to move up and down. The protrusion on the insulating bracket increases the height of the tray 7 and reduces the production cost of the insulating bracket. The insulating bracket is made of insulating material to ensure the accuracy of detection.

[0062] The transfer drive slider 502 realizes movement in the horizontal space by driving the motor to move on the transfer track frame 501, realizes movement in the vertical direction by the extension and retraction of the transfer telescopic motor 503, realizes the tightening and loosening of the motor casing by the transfer clamp motor 504 to perform a gripping operation, and realizes the transfer of the motor casing A between the assembly table 1, the conveying track 61, the rolling and riveting equipment 2 and the finished product table 4. At the same time, when the motor casing A is placed on the rolling and riveting limit column 205 in the rolling and riveting equipment 2, the motor casing A is sleeved on the rolling and riveting limit column 205, and the fixed top core 507 is pushed out from the motor casing. After the motor casing is placed, the transfer clamp motor 504 continues to move downward, and the fixed top core 507 is taken out of the motor casing by using the inner clamp 506 on the transfer clamp motor 504. No manual participation is required throughout the process, and mechanized operation is convenient for assembly line work, saving working time and improving work efficiency.

[0063] The process of using the overall technical solution formed by the above embodiment is as follows: The assembly process of the motor housing A is as follows: the fixed top core 507 is installed at the center of the motor housing, each mounting groove 509 corresponds to an external riveting hole on the motor housing, and the four excitation coils B to be assembled are evenly installed in the gap between the fixed top core 507 and the motor housing, and each excitation coil B corresponds to a mounting groove 509. After the installation is completed, a gasket C with a rivet is placed in each mounting groove 509. After the gasket C is in place, the external riveting hole and the rivet are in the same straight line. At this time, the fixed top core 507 is fixed in the motor housing by its own friction force and the friction force between the gasket C and the excitation coil B. In the absence of external force, it will not slide out of the motor housing by relying on its own gravity. Then the assembled motor housing A is placed on the assembly table 1 in the position to be clamped.

[0064] The process of transferring the motor housing A from the conveying track 61 to the rolling rivet limiting column 205 is as follows: using the transfer driving slider 502 to drive the clamping motor to run above the rolling rivet placement point on the conveying track 61, extending the transfer telescopic motor 503 to lower the transfer clamping motor 504 to the motor housing, and using the transfer clamping motor 504 to control the outer clamping jaw 505 to clamp the motor housing. After clamping, retract the transfer telescopic motor 503 to lift the motor housing, and use the transfer driving slider 502 to drive the motor housing to move on the transfer track frame 501, and move it to the position above the rolling rivet limiting column 205, and extend the rolling rivet telescopic motor to lower the motor housing onto the rolling rivet limiting column 205. When the motor housing moves downward and is sleeved on the rolling rivet limiting column 205, the rolling rivet limiting column 205 will fix the top core 50 in the motor housing. 7 ejects the motor casing. At this time, the rolling rivet clamp motor controls the outer clamp 505 to loosen the motor casing, and further extends the rolling rivet telescopic motor to move downward, so that the inner clamp 506 moves to the inside of the fixed top core 507 and is flush with the annular groove 508 inside the fixed top core 507. After being flush, the rolling rivet clamp motor controls the inner clamp 506 to further pull outward, so that the L-shaped inner clamp 506 enters the inside of the annular groove 508 and is fixed. Finally, the inner clamp 506 telescopic motor is retracted to pull up the fixed top core 507. After the fixed top core 507 is completely out of the working area of ​​the rolling rivet workbench, the rolling rivet driving slider is moved along the rolling rivet track frame to the funnel-shaped placement port of the inclined slide 510. The fixed top core 507 automatically slides from the rolling rivet equipment 2 to the assembly table 1 under the action of gravity, realizing the automatic transportation of the fixed top core 507.

[0065] The process of rolling riveting the motor housing A is as follows: the rolling riveting driving cylinder 209 drives the rolling riveting guide rod 210 to move downward, and the conical section 16 pushes the rolling riveting guide block 15 to move outward along the rolling riveting guide hole 14, pressing the gasket C and the magnetic pole coil B against the inner wall of the motor housing A. At this time, the rolling riveting annular elastic belt 211 undergoes energy storage elastic deformation, and the rolling riveting moving mechanism drives the rolling riveting head 203 to move toward the motor housing A. The rolling riveting motor 202 also drives the rolling riveting head 203 to rotate, completing the rolling riveting connection of the two relative magnetic pole coils B. After the rolling riveting head 203 is reset under the action of the rolling riveting moving mechanism, the rolling riveting reversing motor 207 drives the rolling riveting limit The position column 205 and the pole coil B rotate 90 degrees together, and the riveting moving mechanism pushes the riveting head 203 to move toward the motor housing A again to complete the riveting connection of the remaining two relative pole coils B. After the riveting head 203 is reset again, the riveting reversing motor 207 drives the riveting limit column 205 and the pole coil B to rotate 90 degrees in the opposite direction to reset, and the riveting driving cylinder 209 drives the riveting guide rod 210 to move upward, and the conical section releases the thrust on the riveting guide block. The riveting support block 206 and the riveting guide block are reset under the action of the riveting annular elastic band 211 to complete the riveting connection of the pole coil B on the motor housing A.

[0066] The process of detecting the motor housing A is as follows: when the conveying position sensor detects that the pallet 7 drives the motor housing A that has been riveted to the detection position, the conveying limit block blocks and limits the pallet 7, and the insulating bracket moves upward under the action of the insulating cylinder 304, and lifts the pallet 7 from the conveyor belt 6, breaking away from the contact with the conveying track 61, so that the positive probe 301 and the negative probe 302 are respectively connected to the positive and negative poles of the resistance tester, so that the resistance test circuit is turned on, the resistance test is completed, the test results are recorded and the motor housing A is recorded, so that the qualified and unqualified motor housings A are placed at different positions on the finished product table 4 through the clamping motor in the future. After the test is completed, the insulating bracket is reset, the conveying limit block is reset, and the pallet 7 contacts the conveying track 61 and moves with the conveying track 61.

[0067] The process of pallet 7 moving on the conveying track 61 and the return track 62 is as follows: when pallet 7 moves from the assembly table 1 to the finished product table 4, when the moving position sensor detects that pallet 7 has arrived, the conversion hook 637 hangs the pallet 7 at the tail of the conveying track 61, and then the conversion push-pull cylinder 635 drives the conversion push-pull plate 634 and the conversion hook 637 to move, and drives the pallet 7 to move to the conversion lifting frame 631, and then the conversion lifting cylinder 632 drives the conversion push-pull cylinder 635 and the pallet 7 to move up and down. When the pallet 7 moves to the head of the return track 62, the conversion push-pull cylinder 635 pushes the conversion push-pull plate 634 and the pallet 7 to move toward the head of the return track 62. When the pallet 7 moves to the head of the return track 62, the conversion hook 637 releases the hanging of the pallet 7, and the pallet 7 moves under the drive of the return track 62 and returns to the assembly table 1, thereby completing the reversal of the movement of the pallet 7 and realizing the reversal automation.

[0068] The process of transferring the motor housing A between the assembly table 1, the conveying track 61, the riveting limit column 205 and the finished product table 4, and the pallet 7 between the conveying track 61 and the return track 62 is as follows: the conveying position sensor is used to detect whether a motor housing A has arrived at a specified position, and then the pallet 7 with the motor housing A is limited by the conveying limit block to stop it from moving with the conveying track 61, so as to facilitate the operations of clamping, transferring and detecting the motor housing A.
