Description

Technical Field

[0001] The invention relates to the field of machining, in particular to a production device for a brushless DC motor. Background Art

[0002] When existing brushless DC motors are operating, there is an axial installation error between the rotor shaft and the external shaft of the brushless DC motor. This means that the central axis of the external shaft cannot accurately maintain a collinear state 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 that always acts on the rotor shaft, which causes the rotor shaft to wear and become loose. It also makes it impossible for the stator to drive the rotor shaft in an oblique state to rotate with maximum efficiency, and it also affects the service life of the brushless DC motor. For this reason, as described in patent CN119051340B, a guide ball on the positioning pressure member is pressed against the follower, thereby achieving adaptive pressure on the follower away from the driven shaft, ensuring the stability of the follower transmission, and thus improving the service life of the motor to a certain extent.

[0003] However, when installing the positioning and pressing part on the sleeve body, the worker needs to accurately place the positioning and pressing part on the sleeve cup body and then fix it through welding and other processes. This installation method requires high operating skills of the workers, which makes the labor intensity of the workers high and the installation efficiency low, making it difficult to meet the needs of large-scale production. Summary of the Invention

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

[0005] To achieve the above objectives, the present application adopts the following technical solution: a production device for a brushless DC motor, the production device being used to install a positioning pressure piece on the inner plate of a sleeve body, the lower end of the positioning pressure piece passing through a mounting seat, the outer side of the positioning pressure piece being provided with a spring in the same direction as the positioning pressure piece, one end of the spring being connected to the side wall of the positioning pressure piece, and the other end of the spring being connected to the mounting seat, the mounting seat being pre-assembled with the positioning pressure piece, wherein the mounting seat is located on the end of the positioning pressure piece away from the guide ball, the inner plate of the sleeve body being provided with a mounting hole adapted for the mounting seat, and when the positioning pressure piece is installed, the mounting seat is inserted into the mounting hole. The production device includes a workbench that moves vertically, a turntable being provided at the upper end of the workbench, the turntable rotating about its vertical axis, and an operating hole being provided at the upper end of the turntable concentric with the turntable, during production, the inner plate of the sleeve body is placed in the operating hole and fixed concentrically with the operating hole by a fixing mechanism provided in the operating hole; a clamping mechanism for clamping the positioning pressure piece is provided above the workbench. Compared with the method of installing the spring on the sleeve body, the present invention fixes the spring on the mounting seat, and then installs the mounting seat on the inner plate of the sleeve body, which can reduce the difficulty of assembly and the labor intensity of the staff, thereby improving production efficiency.

[0006] Furthermore, the lower end of the operating hole is open, and the workbench is provided with a through hole connected to the operating hole; and the lower end of the workbench's moving path is provided with an ejector. When the workbench is lowered to a certain height, the ejector passes through the through hole from bottom to top, thereby ejecting the inner plate of the sleeve body from the operating hole, making it easier for workers to remove the inner plate of the sleeve body.

[0007] Furthermore, to enhance automation, a rotating base is provided on one side of the workbench, rotating about a vertical axis. A column is mounted on the upper end of the rotating base, equipped with a vertical drive mechanism that drives a support arm in vertical motion. A transverse drive mechanism is mounted on the support arm, driving a loading plate in transverse motion. Once the inner plate of the sleeve body is ejected from the operating hole, the loading plate extends laterally beneath the inner plate. The loading plate then ascends, carrying the inner plate with it, separating the inner plate from the ejection portion. The loading plate then rotates with the support arm, moving it out of the area above the workbench, making it easier for the operator to retrieve the inner plate. When placing the inner plate of the sleeve body, the operator first places it on top of the carrier plate. The carrier plate moves the inner plate above the operating hole and then descends to place the inner plate on the upper end of the ejector. After the inner plate is caught by the ejector, the carrier plate continues to descend and resets to the far end of the ejector. After the carrier plate is reset, the workbench rises to allow the inner plate to enter the operating hole. The linkage of the support arm, horizontal drive mechanism, vertical drive mechanism, workbench, and ejector allows the inner plate of the sleeve body to be transferred between the operating hole and the manual operation area, reducing manual intervention and labor intensity.

[0008] Furthermore, in order to reduce manual intervention and labor intensity, the clamping mechanism is arranged on the sliding seat. As the sliding seat moves horizontally, the clamping mechanism moves from the loading area to above the turntable, and the positioning pressure piece moves to the loading area of the clamping mechanism under the drive of the feeding mechanism.

[0009] Furthermore, the feeding mechanism includes a frame, a conveying trough is arranged horizontally on the upper end of the frame, a long hole is arranged in the same direction as the conveying trough at the bottom, the bottom of the conveying trough supports the mounting seat, the long hole leaves space for the lower end of the positioning and pressing member, and a conveying belt is arranged in the same direction as the conveying trough on the side wall, the conveying belt is in contact with the mounting seat, and when the conveying belt is working, the positioning and pressing member is driven to move by friction.

[0010] Furthermore, in order to ensure that the clamping mechanism can clamp a positioning and pressing member, the conveying trough is opened at one end along its length direction to form a discharge port, and a baffle is provided at the discharge end, and the baffle moves under the action of a cylinder, an electric push rod, etc.; when the clamping mechanism clamps the positioning and pressing member and performs a translational action, the baffle moves away from the position of the discharge port to avoid interfering with the movement of the positioning and pressing member.

[0011] Furthermore, the bottom of the conveyor trough is provided with rollers arranged along its length, which enables the conveyor belt to more easily drive the positioning and pressing parts to move, thereby improving the operating efficiency of the feeding mechanism and avoiding the unsmooth movement or shaking caused by excessive friction, thereby improving the stability of the transmission. Furthermore, to ensure that the mounting seat is properly installed, the outer wall of the positioning pressure piece and the inner wall of the mounting seat are keyed to achieve circumferential positioning. The clamping mechanism is equipped with a rotation drive mechanism, so that the clamping mechanism can drive the positioning pressure piece to rotate. When the positioning pressure piece rotates, the mounting seat rotates synchronously, so that the mounting seat can be smoothly installed by rotating and coordinating the axial feed. At the same time, to facilitate the subsequent maintenance of the positioning pressure piece by the staff, the mounting seat is threadedly connected to the mounting hole on the inner plate of the sleeve body. In this way, the positioning pressure piece is driven to rotate by the clamping mechanism, which can also more conveniently install the mounting seat on the inner plate of the sleeve body.

[0012] Furthermore, the fixing mechanism includes fixing plates arranged in a circular array around the axis of the operating hole. Driven by a fixed drive mechanism, the fixing plates are fed radially along the operating hole. The radial clamping action of the fixing plates ensures that the inner plate of the sleeve body and the turntable are concentrically positioned and rotate synchronously, significantly improving the positioning accuracy of the inner plate of the sleeve body during machining.

[0013] Furthermore, in order to prevent the inner plate of the sleeve body from falling from the operating hole and not interfere with the ejection and other actions of the inner plate of the sleeve body, a concentric avoidance hole is provided at the bottom of the operating hole, and the inner diameter of the avoidance hole is smaller than the operating hole.

[0014] The beneficial effects of this application are as follows: the mounting base and the positioning and pressing member are pre-assembled together and then fixed as a whole to the inner plate of the sleeve body. This installation method can significantly simplify the on-site assembly process, significantly reducing the difficulty of the 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.

[0015] After the clamping mechanism completes the grasping and positioning of the positioning and pressing member, the workbench realizes the installation of the positioning and pressing member through a vertical lifting action. The entire process does not require manual intervention, further reducing manual operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] 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.

[0024] Example 1, as Figure 1-Figure 3 、 Figure 5-Figure 6 As shown, the specific structure of this embodiment is a production device for a brushless DC motor, which is used to install a positioning and pressing member 1 on the inner plate 2 of the sleeve body. The lower end of the positioning and pressing member 1 passes through the mounting seat 3. The structure of the positioning and pressing member 1 is the same as the positioning and pressing member recorded in CN119051340B. The outer side of the positioning and pressing member 1 is provided with a spring 23 in the same direction as the positioning and pressing member. One end of the spring 23 is connected to the side wall of the positioning and pressing member 1, and the inner plate 2 of the sleeve body and the positioning and pressing member 1 are connected together through the spring 23; the other end of the spring 23 is connected to the mounting seat 3, and the guide ball is pre-installed at one end of the positioning and pressing member 1, and the mounting seat 3 is located on the far side of the guide ball mounting end. A mounting hole is provided on the inner plate 2 of the sleeve body, and the outer diameter of the mounting seat 3 is adapted to the inner diameter of the mounting hole. When installing the positioning pressure piece 1, the mounting seat 3 is inserted into the mounting hole from top to bottom. The mounting hole is set as a countersunk hole with open ends at the upper and lower ends. When the mounting seat 3 is installed on the inner plate 2 of the sleeve body, it can be fixed by bolts, etc. When installing the positioning pressure piece 1, the ball guide end of the positioning pressure piece 1 faces upward.

[0025] The production device includes a workbench 4 that moves vertically. The workbench 4 can be driven by a vertical screw, electric push rod, linear module, etc. that is driven by a motor. Linear guide rails can be installed on both sides of the workbench. The guide rails are fixed to the guide frame in the vertical direction. Sliders are fixed on the workbench, and the slides slide along the guide rails to play a guiding and stabilizing role. A turntable 5 is provided at the upper end of the workbench 4. The turntable 5 rotates around its vertical axis. To this end, a circle of driven gears concentric with it can be provided on the turntable 5. A motor is provided on the workbench 4. The output shaft of the motor is connected to the driving gear through a coupling. The driven gear and the driving gear are meshed. A bearing is provided at the connection between the turntable 5 and the workbench 4. The turntable 5 is driven to rotate by the motor. The current state of the turntable is obtained by a visual sensor, etc., and the rotation angle of the turntable is accurately determined by a rotary encoder, an angle controller, etc.

[0026] The upper end of the turntable 5 is provided with an operating hole 6 concentric therewith. During production, the inner plate 2 of the sleeve body is placed in the operating hole 6 and fixed concentrically with the operating hole 6 by a fixing mechanism provided in the operating hole 6. Since the lower end surface of the positioning and pressing member 1 will extend beyond the lower end surface of the mounting seat 3, a clearance hole 22 concentric therewith is provided at the bottom of the operating hole 6. At the same time, in order to prevent the inner plate 2 of the sleeve body from falling after being placed in the operating hole 6 but before being fixed by the fixing mechanism, the inner diameter of the clearance hole 22 is smaller than the inner diameter of the operating hole 6. In this embodiment, the fixing mechanism includes a fixing plate 21 arranged in a circular array along the axis of the operating hole 6. The fixing plate 21 moves radially along the operating hole 6 under the action of a fixing drive mechanism. The fixing drive mechanism can be a hydraulic cylinder, an electric push rod, etc. The contact surface between the fixing plate 21 and the inner plate 2 of the sleeve body is set to an arc surface that is compatible with the outer wall of the inner plate 2 of the sleeve body. A clamping mechanism 7 for clamping the positioning and pressing member 1 is provided above the workbench 4 . The clamping mechanism 7 may be a pneumatic clamping finger, a bidirectionally movable clamping plate, or the like.

[0027] Specific production process: The mounting seat 3 and the positioning and pressing member 1 are assembled together, and the two ends of the spring 23 are respectively fixed on the mounting seat 3 and the positioning and pressing member 1 by welding or other means.

[0028] The positioning pressing member 1 is fixed in a vertical posture by the clamping mechanism 7, and the inner plate 2 of the sleeve body is placed horizontally in the operating hole 6 of the turntable 5. The fixing plate 21 clamps the inner plate 2 of the sleeve body to ensure its stable installation and synchronous movement with the turntable 5.

[0029] After the above preparations are completed, the workbench 4, carrying the inner plate 2 of the sleeve body, rises vertically, allowing the lower end of the positioning and pressing member 1 to be accurately inserted into the corresponding mounting hole of the inner plate 2 of the sleeve body. When the bottom surface of the mounting seat 3 forms surface contact with the step in the mounting hole, the press-fitting of the single positioning and pressing member 1 is completed. The workbench 4 then descends and resets, and the turntable 5, driven by a servo motor, rotates at an indexing speed, quickly switching to the next station for repeated press-fitting. This improves assembly efficiency and reduces the operator's labor intensity.

[0030] After all the positioning and pressure members 1 are installed, the sleeve body inner plate 2 is removed from the turntable 5 and then fixed to the sleeve body using bolts, welding, etc. Compared to the installation method of directly fixing the spring to the inner wall of the sleeve body, the installation method of the present invention allows for the rapid replacement of the positioning and pressure members 1 according to maintenance needs, significantly reducing maintenance difficulty and spare parts replacement costs.

[0031] Example 2, as Figure 1-Figure 3As shown, the other structures and production processes of this embodiment are the same as those of Example 1. However, in this embodiment, in order to improve the level of automation, the lower end of the operating hole 6 is open, and a through hole 8 connected to the operating hole 6 is provided on the workbench 4; an ejector 9 is provided at the lower end of the moving path of the workbench 4. During the vertical descent of the workbench 4, the ejector 9 passes through the through hole 8 from bottom to top and enters the operating hole 6.

[0032] A rotating base 10 that rotates around a vertical axis is provided on one side of the workbench 4. The rotating base 10 can be driven by a servo motor and can achieve indexing positioning. A column 11 is provided on the upper end of the rotating base 10. A vertical driving mechanism is provided on the column 11. The vertical driving mechanism can adopt a ball screw module, etc., and is driven by a servo motor. The vertical driving mechanism drives the support arm 12 to move vertically. A horizontal driving mechanism 13 is provided on the support arm 12. The horizontal driving mechanism 13 can adopt a hydraulic cylinder, an electric push rod, etc. The horizontal driving mechanism 13 drives the loading plate 14 to move horizontally. The loading plate 14 is used to support the inner plate 2 of the sleeve body.

[0033] The specific working process is as follows: After the sleeve body inner plate 2 is ejected from the operating hole, the loading plate 14 extends horizontally under the sleeve body inner plate 2. Then, the loading plate 14 carries the sleeve body inner plate 2 upward, separating the sleeve body inner plate 2 from the ejection portion 9. Then, the loading plate 14 and the sleeve body inner plate 2 rotate along with the support arm 12, thus moving out of the area above the workbench 4, making it easier for the operator to remove the sleeve body inner plate.

[0034] When placing the inner plate 2 of the sleeve body, the staff first places it above the loading plate 14. The loading plate 14 moves the inner plate 2 of the sleeve body to above the operating hole 6 and then descends to place the inner plate 2 of the sleeve body on the upper end of the ejection part 9. After the inner plate 2 of the sleeve body is caught by the ejection part 9, the loading plate 14 continues to descend and reset to the far end of the ejection part 9; after the loading plate 14 is reset, the workbench 4 rises to allow the inner plate 2 of the sleeve body to enter the operating hole from top to bottom.

[0035] Example 3, as Figures 1-6 As shown, the other structures and production processes of this embodiment are the same as those of Embodiment 1 or 2. However, in this embodiment, the clamping mechanism 7 is disposed on a sliding seat 15. The sliding seat 15 is driven by a ball screw, a linear module, etc. to move in the transverse direction, thereby driving the clamping mechanism 7 to move from the loading area to above the turntable 5. The positioning and pressing member is driven by the feeding mechanism to move to the loading area of the clamping mechanism 7.

[0036] The feeding mechanism includes a frame 16, which serves as the basic support structure for the entire feeding mechanism. Frame 16 is provided with a conveyor trough 17, which is arranged horizontally. The bottom of the conveyor trough 17 is provided with an elongated hole in the same direction as the conveyor trough. The bottom of the conveyor trough 17 is used to support the mounting seat. The elongated hole leaves space for the lower end of the positioning and pressing member 1, ensuring that the positioning and pressing member 1 can maintain a stable and correct posture during conveying. The bottom of the conveyor trough 17 is provided with rollers 20 on both sides of the elongated hole, and the rollers 20 are arranged along the length of the conveyor trough 17. The side walls of the conveyor trough 17 are provided with a conveyor belt 18 in the same direction as the conveyor belt. The conveyor belt 18 can be in the form of a belt conveyor, etc., and is arranged vertically, and the conveyor belt 18 contacts the outer wall of the mounting seat 3. The conveyor trough 17 is open at one end along its length, forming a discharge port. A baffle 19 is provided at the discharge end, and the baffle 19 is movable by a drive device such as a cylinder. When the clamping mechanism 7 clamps the positioning and pressing member 1 and performs a translational motion, the baffle 19 moves away from the position of the discharge port.

[0037] Specific working process: The mounting seat and positioning pressure member 1 are placed in the conveying trough 17 of the feeding mechanism. The roller 20 at the bottom of the conveying trough 17 and the conveyor belt 18 work together to smoothly convey the mounting seat and positioning pressure member 1 forward along the direction of the conveying trough 17 until the mounting seat 3 on the frontmost positioning pressure member 1 abuts the baffle 19. At this time, the conveyor belt 18 stops working. A proximity switch, touch switch, etc. can be set at the baffle 19 to detect the position of the positioning pressure member 1, thereby realizing the automatic start and stop of the conveyor belt 18.

[0038] The jaws of the gripping mechanism 7 move in an open position to the loading area to grip the positioning and pressing member 1 at the front end of the conveying trough 17. After the gripping mechanism 7 grips the positioning and pressing member 1, the baffle 19 moves away from the discharge port, and the gripping mechanism 7 then performs a translational movement. When the positioning and pressing member 1 has completely passed through the discharge port, the baffle 19 returns to its initial position under the control of the drive device, ready to receive the next positioning and pressing member 1.

[0039] The clamping mechanism 7 carries the positioning and pressing member 1 and moves it to the designated installation position above the turntable 5 to install the positioning and pressing member 1. After the installation is completed, the clamping claws of the clamping mechanism 7 open, release the positioning and pressing member 1, and then return to the initial position to prepare for the clamping and installation operation of the next positioning and pressing member 1.

[0040] Example 4, as Figure 1-Figure 2As shown, the other structures and production processes of this embodiment refer to Examples 1-3. However, in this embodiment, the outer wall of the positioning and pressure member 1 and the inner wall of the mounting seat 3 are connected by a key to achieve circumferential positioning. Specifically, the outer wall of the positioning and pressure member 1 is provided with a guide rail along the axial direction, and the inner wall of the mounting seat 3 is provided with a corresponding slide groove. The two are connected by a key through the cooperation of the guide rail and the slide groove, ensuring that the positioning and pressure member 1 and the mounting seat 3 rotate synchronously during rotation, avoiding circumferential displacement and ensuring installation accuracy.

[0041] The gripping mechanism 7 can be implemented as pneumatic gripping fingers or bidirectionally movable gripping plates. A rotary drive mechanism is provided to rotate the gripping mechanism 7 about its vertical axis. When the gripping mechanism 7 is mounted on the sliding base 15, the two are connected via bearings. A rotary drive motor mounted on the sliding base 15 drives the gripping mechanism 7 through a gear transmission.

[0042] During the installation of the positioning and pressure member 1 on the sleeve body inner plate 2, the rotary drive mechanism of the clamping mechanism 7 operates, driving the positioning and pressure member 1 to rotate, and the mounting seat 3 rotates synchronously via a key connection. Simultaneously, the workbench 4 drives the sleeve body inner plate 2 axially, screwing the mounting seat 3 into the mounting hole of the sleeve body inner plate 2. In this embodiment, the mounting seat 3 and the mounting hole of the sleeve body inner plate 2 are connected by threads, facilitating subsequent maintenance.
