Description

Technical Field

[0001] The present invention relates to the field of machining, and specifically to a production device for components of a direct current brushless motor. Background Art

[0002] When an existing direct current brushless motor works, due to the axial installation error between the rotor shaft of the direct current brushless motor and the external shaft, that is to say, the central axis of the external shaft cannot accurately ensure that it is collinear with the central axis of the rotor shaft. As a result, after the external shaft is installed on the rotor shaft, there is a lateral force acting on the rotor shaft all the time, which leads to wear and looseness of the rotor shaft, and makes the stator unable to drive the rotor shaft in an inclined state with the maximum efficiency, and also affects the service life of the direct current brushless motor. For this reason, in patent CN119051340B, the guide ball on the positioning pressing member abuts against the driven member, so as to realize the adaptive pressing of the driven member far from the driven shaft rod, ensure the stability of the driven member transmission, and thus improve the service life of the motor to a certain extent.

[0003] However, when installing the positioning pressing member on the bushing body, the staff needs to accurately place the positioning pressing member on the bushing cup body, and then fix it by processes such as welding. This installation method requires high operation skills of the workers, resulting in high labor intensity of the staff and low installation efficiency, and it is difficult to meet the requirements of large-scale production. Summary of the Invention

[0004] The purpose of the present invention is to solve the above problems and provide a production device for components of a direct current brushless motor, which can reduce the labor intensity of the staff.

[0005] To achieve the above object, the technical solution adopted in this application is as follows: A production device for parts of a DC brushless motor. The parts of the DC brushless motor include a positioning and pressing member and an inner plate of the bushing body. A spring in the same direction as the positioning and pressing member is sleeved outside the positioning and pressing member, and one end of the spring is connected to the side wall of the positioning and pressing member; the other end of the spring is connected to the mounting seat. Both ends of the positioning and pressing member extend out of the mounting seat. The circumferential positioning between the outer side wall of the positioning and pressing member and the inner side wall of the mounting seat is realized by a key connection method. The mounting seat is installed on the inner plate of the bushing body; the production device includes a turntable, which is rotatably arranged on the workbench around its vertical axis. An operation hole concentric with the turntable is arranged on the turntable. A clearance hole is arranged at the bottom of the operation hole. A fixing mechanism for fixing the inner plate of the bushing body is arranged in the operation hole. During production, the inner plate of the bushing body is placed in the operation hole, and the inner plate of the bushing body is fixed to a state concentric with the operation hole through the fixing mechanism. The mounting seat is pre-assembled with the positioning and pressing member, and the mounting seat is located at the end of the positioning and pressing member away from the guide ball. Compared with the method of installing the spring on the bushing body, in the present invention, the spring is fixed on the mounting seat, and then the mounting seat is installed on the inner plate of the bushing body, which can reduce the assembly difficulty, reduce the labor intensity of the staff, and thus improve the production efficiency. Through the turntable, the installation position of the positioning and pressing member can be quickly changed to further reduce the working difficulty and improve the production efficiency.

[0006] Further, the lower end of the clearance hole is open. A through hole communicating with the clearance hole is arranged on the workbench, and a top plate moving vertically is further arranged below the workbench. The inner plate of the bushing body is ejected from the operation hole by the top plate to facilitate the staff to take the inner plate of the bushing body.

[0007] Further, to improve the automation level, a rotating arm is arranged on one side of the workbench. The rotating arm rotates around the vertical axis. A transverse driving mechanism is arranged on the rotating arm, and the transverse driving mechanism drives the carrier plate to move horizontally. When the inner plate of the bushing body is ejected from the operation hole, the carrier plate extends under the inner plate of the bushing body to catch the inner plate of the bushing body. When the top plate descends, the carrier plate and the inner plate of the bushing body rotate together with the rotating arm to move away from above the workbench to facilitate the staff to take; when placing the inner plate of the bushing body, the staff places the inner plate of the bushing body above the carrier plate. The carrier plate moves the inner plate of the bushing body above the operation hole. After the top plate supports the lower end of the inner plate of the bushing body, the carrier plate retreats and resets, and then the top plate descends to place the inner plate of the bushing body in the operation hole. Through the linkage of the rotating arm, the transverse driving mechanism and the top plate, the automatic transfer of the inner plate of the bushing body between the operation hole and the manual operation area is realized, reducing manual intervention and lowering the labor intensity.

[0008] Further, to improve the installation stability and maintainability of the mounting seat, the mounting seat is threadedly connected to the inner plate of the bushing. For this purpose, a lifting seat moving vertically is provided below the workbench. The upper end of the lifting seat is provided with a support rotating about the vertical axis. A clamping mechanism is provided on the support. To drive the mounting seat to rotate, the outer side wall of the positioning and pressing member and the inner side wall of the mounting seat are key-connected.

[0009] Further, the positioning and pressing member is moved above the turntable under the action of the feeding mechanism to facilitate the operator to pick up the positioning and pressing member.

[0010] Further, to reduce manual intervention and labor intensity, the feeding mechanism includes a frame. A conveying groove is provided horizontally on the frame. A long hole in the same direction as the conveying groove is provided at the bottom of the conveying groove. A conveyor belt in the same direction as the conveying groove is provided on the side wall of the conveying groove. The bottom of the conveying groove supports the mounting seat. The long hole leaves space for the lower end of the positioning and pressing member. The conveyor belt contacts the mounting seat. When the conveyor belt works, it drives the positioning and pressing member to move through friction.

[0011] Further, one end of the conveying groove in its length direction is open for discharging. A loading part is provided at the discharging end of the frame. The loading part moves horizontally. The feeding mechanism further includes a transfer mechanism. The transfer mechanism includes a clamping part for clamping the positioning and pressing member on the loading part. The clamping part is provided on a vertically moving part, and the vertically moving part moves vertically. The positioning and pressing member moved out of the frame is caught by the loading part, and then the conveyor belt stops working. The clamping part clamps the positioning and pressing member, and the loading part separates from the positioning and pressing member. Then, the clamping part descends with the positioning and pressing member and places the positioning and pressing member in the installation area of the inner plate of the bushing.

[0012] Further, to catch the positioning and pressing member, a receiving groove is provided at the upper end of the loading part. The receiving groove is open on one side of the frame and closed at the far end of the frame. A receiving hole is provided through the bottom of the receiving groove.

[0013] Further, rollers are arranged along the length direction at the bottom of the conveying groove. This enables the conveyor belt to drive the positioning and pressing member more easily, improves the operating efficiency of the feeding mechanism, and at the same time avoids the phenomenon of unsmooth movement or jitter caused by excessive friction, thereby improving the transmission stability.

[0014] Further, the fixing mechanism includes a plurality of fixing plates arranged in a circular array along the axis of the operation hole. The fixing plates can move radially along the operation hole under the action of the fixing driving mechanism. The inner plate of the bushing is clamped by the fixing plates to ensure that the inner plate of the bushing moves synchronously with the turntable, improving the position accuracy of the inner plate of the bushing during the production process.

[0015] The beneficial effects of this application are as follows: by securing the spring to the mounting seat, then installing the mounting seat on the inner plate of the sleeve body, and pre-assembling the mounting seat and the positioning and pressing member, the on-site installation process can be simplified. This significantly reduces the operational difficulty for workers during the assembly process, thereby reducing labor intensity and making it easier to complete the installation of the positioning and pressing member, thereby improving production efficiency. In addition, by driving the inner plate of the sleeve body to rotate via a turntable, the installation position of the positioning and pressing member can be quickly changed, further improving production efficiency.

[0024] In order to enable those skilled in the art to better understand the technical solution of the present application, the present application is described in detail below with reference to the accompanying drawings. The description in this section is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present application.

[0025] Example 1, as Figures 1-3As shown in the figure, the specific structure of this embodiment is a production device for components of a DC brushless motor. The components of the DC brushless motor include a positioning and pressing member 1 and an inner plate 2 of the bushing body. A spring 3 in the same direction as the positioning and pressing member 1 is sleeved outside the positioning and pressing member 1, and one end of the spring 3 is connected to the side wall of the positioning and pressing member 1; the other end of the spring 3 is connected to the mounting seat 4. The required guide balls can be installed at one end of the positioning and pressing member 1 in advance, and the mounting seat 4 is located on the far side of the guide ball installation end. Both ends of the positioning and pressing member 1 extend out of the mounting seat 4, and the mounting seat 4 is installed on the inner plate 2 of the bushing body by means of nesting, threaded buckles, etc. In this embodiment, when the positioning and pressing member 1 is installed on the inner plate 2 of the bushing body, the guide ball end of the positioning and pressing member 1 faces upward.

[0026] The production device includes a turntable 5, which is rotatably arranged on a workbench 6 around its vertical axis. To drive the turntable 5 to move, a toothed ring concentric with the turntable 5 can be arranged on the turntable 5, and the toothed ring meshes with the driving gear on the motor. The motor is installed on the workbench 6, and a bearing is arranged at the connection between the turntable 5 and the workbench 6. The state of the current turntable 5 is obtained through a vision sensor, etc., and the rotation angle of the turntable is accurately determined through a rotary encoder, an angle controller, etc.

[0027] An operation hole 7 concentric with the turntable 5 is arranged on the turntable 5, and an avoidance hole 8 is arranged at the bottom of the operation hole 7. The purpose of arranging the avoidance hole 8 is to leave a placement space for the lower end of the positioning and pressing member 1, so that the lower end plane of the mounting seat 4 is supported by the bottom of the operation hole 7, avoiding the skew of the positioning and pressing member 1 during installation. A fixing mechanism for fixing the inner plate 2 of the bushing body is arranged in the operation hole 7. In this embodiment, the fixing mechanism includes fixing plates 23 arranged in an annular array along the axis of the operation hole. The fixing plates 23 move radially along the operation hole 7 under the action of a fixing driving mechanism, so that the fixing plates 23 contact the outer side wall of the inner plate 2 of the bushing body. The contact surface between the fixing plates 23 and the inner plate 2 of the bushing body is set as an arc surface adapted to the outer side wall of the inner plate 2 of the bushing body. The fixing driving mechanism can adopt a hydraulic cylinder, an electric push rod, etc.

[0028] Specific production process: The mounting seat 4 and the positioning and pressing member 1 are assembled together, and both ends of the spring are respectively fixed on the mounting seat 4 and the positioning and pressing member 1 by welding or other means.

[0029] When installing the positioning and pressing member 1, the staff first place the inner plate 2 of the bushing body in the operation hole 7 of the turntable 5, and the fixing plate 23 of the fixing mechanism moves radially to clamp the inner plate 2 of the bushing body, ensuring its stable installation and synchronous movement with the turntable 5. Then the staff insert the lower end of the positioning and pressing member 1 into the installation hole of the inner plate 2 of the bushing body. The installation hole is a counterbore with both upper and lower ends open. Through the rotation function of the turntable 5, the position of the inner plate 2 of the bushing body is quickly adjusted, so as to quickly install a plurality of positioning and pressing members 1 on the inner plate 2 of the bushing body, improving production efficiency and reducing labor intensity.

[0030] After the positioning and pressing member 1 is installed, the inner plate 2 of the bushing body is taken out from the turntable 5, and then the inner plate 2 of the bushing body is fixed to the bushing body by means of bolts, welding, etc. Compared with the installation method of directly fixing the spring on the inner wall of the bushing body, the installation method of the present invention can quickly replace the positioning and pressing member 1 according to the maintenance requirements, significantly reducing the maintenance difficulty and the spare part replacement cost.

[0031] Example 2, as Figure 1 , Figure 2 , Figure 7 shown, the other structures and production processes of this embodiment are the same as those of Example 1. However, in this embodiment, to improve the automation level, the lower end of the clearance hole 8 is open, a through hole 10 communicating with the clearance hole 8 is provided on the workbench 6, and a top-out driving mechanism 25 is provided below the workbench 6. The top-out driving mechanism 25 can adopt existing technologies such as cylinders and electric push rods. The output end of the top-out driving mechanism 25 moves vertically, and the upper end of the top-out driving mechanism 25 is fixedly connected to the top-out plate 11.

[0032] A column 26 is provided on one side of the workbench 6, and a rotary driving mechanism is provided at the upper end of the column 26. The rotary driving mechanism can adopt mechanisms in existing technologies such as hydraulic turntables and motors that can drive objects to rotate. The rotary driving mechanism drives the rotary arm 12 to rotate around the vertical axis. Two rotary arms 12 can be provided. When the rotary arms 12 rotate to below the inner plate 2 of the bushing body, they are respectively placed on both sides of the axis of the inner plate 2 of the bushing body. A transverse driving mechanism 13 is provided on the rotary arm 12. The transverse driving mechanism 13 can adopt cylinders, electric push rods, etc. The transverse driving mechanism 13 drives the carrier plate 14 to move horizontally.

[0033] A lifting seat 21 that moves vertically is provided below the workbench 6. The lifting seat 21 moves under the drive of cylinders, hydraulic cylinders, electric push rods, etc. A support 22 is provided at the upper end of the lifting seat 21. The support 22 rotates around the vertical axis under the drive of a motor, etc. A clamping mechanism 9 is provided on the support 22. The clamping mechanism 9 can adopt existing pneumatic fingers and other mechanisms that can clamp materials. The clamping jaws of the clamping mechanism 9 are set as arcs adapted to the lower part of the positioning and pressing member 1; The mounting seat 4 is threadedly connected to the inner plate 2 of the bushing body. The outer side wall of the positioning and pressing member 1 and the inner side wall of the mounting seat 4 are key-connected. In this embodiment, a slide rail is axially provided on the outer side wall of the positioning and pressing member 1, and a chute is provided on the inner side wall of the mounting seat 4. The positioning and pressing member 1 and the mounting seat 4 are key-connected through the cooperation of the slide rail and the chute, so that the positioning and pressing member 1 and the mounting seat 4 can rotate synchronously.

[0034] Specific production process: The inner plate 2 of the bushing body to be assembled is placed on the upper end of the carrier plate 14 through an automatic feeding device or manually. Then, the carrier plate 14 rotates to directly above the ejector plate 11. At this time, the ejector plate 11 rises to support the lower end of the inner plate 2 of the bushing body and separate the carrier plate 14 from the inner plate 2 of the bushing body. The carrier plate 14 retreats and resets under the drive of the lateral drive mechanism 13, moving away from below the inner plate 2 of the bushing body. After the carrier plate 14 is separated from the inner plate 2 of the bushing body, the ejector plate 11 carrying the inner plate 2 of the bushing body descends until the lower end of the inner plate 2 of the bushing body is supported by the operation hole 7. After the inner plate 2 of the bushing body is supported by the bottom of the operation hole 7, the fixing plate 23 in the fixing mechanism moves radially inward along the operation hole 7 under the action of the fixing drive mechanism, clamping the inner plate 2 of the bushing body to ensure its synchronous rotation with the turntable 5.

[0035] After the inner plate 2 of the bushing body is fixed, the mounting seat 4 on the positioning and pressing member 1 is inserted into the mounting hole on the inner plate 2 of the bushing body. At this time, the lower end face of the mounting seat 4 is in surface contact with the stepped forming surface in the mounting hole, and the lower part of the positioning and pressing member 1 extends out of the lower end of the inner plate 2 of the bushing body. Then, the clamping mechanism 9 rises to clamp the lower part of the positioning and pressing member 1. Subsequently, the clamping mechanism 9 descends simultaneously with the support 22 to tighten the mounting seat 4 on the inner plate 2 of the bushing body.

[0036] After all the positioning and pressing members 1 are installed, the fixing plate 23 is separated from the inner plate 2 of the bushing body, and the ejector plate 11 rises to eject the inner plate 2 of the bushing body from the operation hole 7 until the lower end face of the inner plate 2 of the bushing body is higher than the upper end face of the carrier plate 14. After the inner plate 2 of the bushing body rises to the specified height, the lateral drive mechanism 13 on the rotating arm 12 is activated to drive the carrier plate 14 to move laterally, making it extend below the inner plate 2 of the bushing body to catch the inner plate 2 of the bushing body. Subsequently, the rotating arm 12 rotates to move the inner plate 2 of the bushing body away from the workbench 6 to facilitate subsequent assembly or for the staff to take it, etc.

[0037] Embodiment 3, as Figure 1 、 Figure 4 、 Figure 5 、 Figure 6 shown, the other structures and production processes of this embodiment refer to Embodiment 1 or 2. However, in this embodiment, the positioning and pressing member 1 moves above the turntable 5 under the action of the feeding mechanism. The feeding mechanism includes a frame 15. A conveying groove is arranged horizontally on the frame 15. The bottom of the conveying groove supports the mounting seat 4 to carry the positioning and pressing member 1. A long hole 16 in the same direction as the conveying groove is arranged at the bottom of the conveying groove, and the long hole 16 is used to accommodate the part of the positioning and pressing member 1 located below the mounting seat 4.

[0038] On the side walls on both sides of the conveying trough, conveyor belts 17 are provided. The conveyor belts 17 can be belt conveyors or the like. The conveyor belts of the conveyor belts 17 are arranged vertically. The conveyor belt of the conveyor belt 17 contacts the side wall of the mounting seat 4 to drive the positioning and pressing member 1 to move. One end of the conveying trough in its length direction is open for discharging materials. A loading part 18 is provided at the discharging end of the frame 15. The loading part 18 moves horizontally under the drive of a cylinder or the like, so as to move out of the moving path of the transfer mechanism. A receiving groove is provided at the upper end of the loading part 18. The receiving groove is open on one side of the frame 15 and closed at the far end of the frame 15. A receiving hole is provided through the bottom of the receiving groove. The receiving hole is used to accommodate the part of the positioning and pressing member 1 located below the mounting seat 4. The feeding mechanism further includes a transfer mechanism. The transfer mechanism includes a clamping part 19. The clamping part 19 can be pneumatic fingers or the like. The clamping part 19 is used to clamp the positioning and pressing member 1 on the loading part 18. The clamping part 19 is arranged on a vertical moving part 20. The vertical moving part 20 moves vertically under the drive of a cylinder, an electric push rod or the like. Rollers 24 are arranged along the length direction of the bottom of the conveying trough to reduce the friction when the positioning and pressing member 1 moves.

[0039] Specific production process: Start the conveyor belt 17 to drive the positioning and pressing member 1 in the conveying trough to move along the conveying trough towards the discharging end. The rollers 24 cooperate with the conveyor belt 17 to reduce the friction between the bottom of the positioning and pressing member 1 and the conveying trough, ensuring a smooth conveying process. When the positioning and pressing member 1 closest to the discharging end reaches the discharging end of the conveying trough, at this time, the loading part 18 that has stopped at the discharging end in advance catches the positioning and pressing member 1. Under the push of the subsequent positioning and pressing members 1, the positioning and pressing member 1 slides into the receiving groove of the loading part 18. The closed end of the receiving groove is used to limit the moving distance of the positioning and pressing member 1, ensuring that only one positioning and pressing member 1 can enter the loading part 18 each time. The upper end surface of the positioning and pressing member 1 entering the loading part 18 is higher than the upper end surface of the loading part 18. When the side surface of the mounting seat 4 on the positioning and pressing member 1 abuts against the closed end surface of the receiving groove, the conveyor belt 17 stops working.

[0040] After the conveyor belt 17 stops working, the clamping part 19 clamps the part of the positioning and pressing member 1 located above the mounting seat 4, and then the loading part 18 moves away from the positioning and pressing member 1. The way of moving away can be that the loading part 18 moves away from the frame 15 along the length direction of the frame 15, or alternatively, after the clamping part 19 clamps the positioning and pressing member 1, it rises, so that the positioning and pressing member 1 is separated from the loading part 18, and then the loading part 18 moves along the width direction of the frame 15. After the loading part 18 moves away from the positioning and pressing member 1, the clamping part 19 clamps the positioning and pressing member 1 and descends to place the positioning and pressing member 1 into the mounting hole on the inner plate 2 of the bushing body.
