Description

TECHNICAL FIELD

[0002] In the trial-manufacturing process of the axial magnetic flux motor, the stator and motor shell subassembly and the rotor subassembly of the axial magnetic flux motor often need to be disassembled and assembled, and in the process of assembling the stator and motor shell subassembly to the outside of the rotor subassembly (the assembly between the stator and motor shell subassembly and the rotor subassembly) and disassembling the stator and motor shell subassembly from the rotor subassembly (the disassembly between the stator and motor shell subassembly and the rotor subassembly), without the aid of special tooling, the rotor magnetism is very large, which easily causes the stator and rotor to fail to guarantee coaxiality during the assembling process, resulting in part collision and failure to assemble the assembly.

[0003] In the related art, a patent with the publication number CN217240517U discloses an electric spindle maintenance tooling, which comprises a mobile workbench truck, an electric spindle stator part and an electric spindle rotor part. The top of the mobile workbench truck is provided with a connecting mechanism that avoids the failure to disassemble due to the strong magnetic field inside during disassembly maintenance. The electric spindle maintenance tooling fixes the electric spindle rotor part by inserting the electric spindle into the retainer and connecting the nut with the sliding bracket. After loosening the front and rear bearing end cover fixing bolts, the mobile sliding plate is moved, and the sliding block of the sliding table moves horizontally along the sliding rail to overcome the strong magnetic field effect, slowly separate, gradually extract the electric spindle rotor part and the front end cover part, and then place the rotor and bearing group on the rotor maintenance placing seat to exchange new bearings, assemble, and solve the problem of strong attraction caused by the strong magnetic field inside the electric spindle, which makes the electric spindle unable to be effectively separated and installed.

[0004] Although the structure can solve the assembly of conventional single-stator motors, it cannot complete the synchronous movement and assembly of the stators at both ends of the axial magnetic flux motor. Therefore, it is necessary to research and improve the above structure to provide an axial magnetic flux motor high-precision trial-manufacturing and assembling machine, so as to achieve a more practical and valuable purpose. SUMMARY

[0021] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0022] To address the deficiencies or one of the deficiencies in the foregoing background art, the embodiments of the present application provide an axial flux motor high-precision trial-manufacturing and assembling machine, which can solve the problem of part scrapping caused by high-precision assembly of strong magnetic double-stator single-rotor axial flux motor, and ensure the assembly precision of the double-stator single-rotor axial flux motor.

[0023] Referring to FIG. 1, Figures 1 to 3 The embodiments of the present application provide an axial flux motor high-precision trial-manufacturing and assembling machine, which comprises: a workbench 100; a stator loading mechanism comprising two mounting racks 1 slidingly connected to the workbench 100, and a driving assembly 2 for driving the two mounting racks 1 to move closer to or away from each other; a rotor supporting mechanism comprising a supporting seat 3 disposed on the workbench 100 and located between the two mounting racks 1, and a jacking member for driving the supporting seat 3 to move up and down; a rotor supporting mechanism comprising a supporting seat 3 disposed on the workbench 100 and located between the two mounting racks 1, and a jacking member for driving the supporting seat 3 to move up and down;

[0024] In the motor trial-manufacturing and assembling process of the assembling machine, the double mounting racks 1 of the stator loading mechanism can realize precise alignment of the left / right stator and the shell subassembly through cooperative driving.

[0025] The supporting seat 3 of the rotor supporting mechanism completes the switching between high-position placement and low-position avoidance under the driving of the jacking member, and cooperates with the clamping and positioning function of the center shaft 5 to effectively solve the problem of adsorption deviation between the strong magnetic rotor and the stator.

[0026] When the two stator and shell subassemblies move towards the middle rotor subassembly, the center shaft 5 and the mounting rack 1 form double constraints to ensure the synchronicity and stability of the assembling action, and finally realize the high-precision assembling effect of zero part collision and assembly tolerance control within ±0.05mm.

[0027] Exemplarily, the stator and shell subassembly can be detachably connected with the mounting frame 1 through bolt fixation or pneumatic clamps, ensuring positioning reliability when moving with the mounting frame 1. The telescopic drive of the center axis 5 is preferably a pneumatic cylinder or an electric cylinder scheme, in which the pneumatic cylinder has fast response speed and low cost, and the electric cylinder is convenient for integrated closed-loop control.

[0028] The driving assembly 2 adopts a double-sided electric sliding table structure, and realizes linear motion with millimeter-level precision through a servo motor driving a ball screw. The jacking member is also configured with a pneumatic cylinder or an electric cylinder, which cooperates with the electric sliding table to form timing control of the assembly action.

[0029] For example, in the initial stage of assembly, the jacking member lifts the support seat 3 to the rotor placement height, and after the center axis 5 clamps the rotor, the support seat 3 is lowered to the avoiding position, at which time the electric sliding table drives the mounting frame 1 to advance to the middle at a preset speed, completing the axial press-fitting action.

[0030] In some optional embodiments, referring to Figures 1 to 3 The embodiment of the present application provides an axial flux motor high-precision trial-manufacturing and assembly machine, and the two center axes 5 of the axial flux motor high-precision trial-manufacturing and assembly machine are coaxial and oppositely arranged, and the avoiding holes for the two center axes 5 to penetrate are arranged on the mounting frames 1 on the two sides.

[0031] The two center axes 5 of the embodiment of the present application are coaxial and oppositely arranged, and the axial positioning reference of the rotor subassembly is formed through precise alignment. After the center axis 5 penetrates the avoiding hole of the mounting frame 1, the center axis 5 supports the end of the rotor subassembly, so that the rotor subassembly always keeps center alignment during the axial assembly process.

[0032] The arrangement of the avoiding hole not only provides a movement channel for the center axis 5, but also avoids mechanical interference between the mounting frame 1 and the center axis 5 through space reservation, and in combination with the sliding adjustment function of the mounting frame 1, millimeter-level precision alignment of the stator and shell subassembly and the rotor subassembly can be realized.

[0033] The structure design makes the assembly path completely extend along the axial direction, eliminates the assembly stress concentration problem caused by the traditional eccentric positioning, and cooperates with the servo control system to control the assembly coaxiality to be within 0.02 mm.

[0034] Exemplarily, the mounting frame 1 adopts an L-shaped frame structure, the vertical side wall of which is reinforced through rib plate welding, and the horizontal bottom plate forms a sliding pair with the guide rail on the workbench 100. The avoiding hole is arranged on the side wall of the L-shaped plate, the hole diameter is 0.1 to 0.2 mm larger than the diameter of the center axis 5, and the inner wall is finely ground to ensure smooth movement.

[0035] When the mounting frame 1 carries the stator and shell subassembly to move to the middle, the avoidance hole and the top axis 5 form a dynamic gap, so that the rotor subassembly is always in a constrained state, and the dynamic gap restricts the bending deformation amount of the top axis 5, and ensures the assembly coaxiality of the stator and shell subassembly and the rotor subassembly.

[0036] In some optional embodiments, referring to Figures 1 to 3 As shown in the figure, the embodiment of the application provides an axial flux motor high-precision trial-manufacturing and assembly machine, the top axis 5 is threadedly connected to the top seat 4, and the opposite ends of the two side top axes 5 are respectively connected with hand wheels 6.

[0037] The top axis 5 of the embodiment of the application forms a rigid transmission pair with the top seat 4 through a threaded connection structure, the axial position of the top axis 5 can be accurately adjusted by rotating the hand wheel 6, and micron-level positioning of the rotor subassembly is realized.

[0038] Compared with the traditional key connection, the threaded connection design not only ensures the torque transmission efficiency when the top axis 5 rotates, but also prevents the positioning from loosening due to vibration during assembly through the self-locking characteristic.

[0039] For example, the top seat 4 is welded and fixed on the workbench 100, the threaded connection part adopts trapezoidal threads to improve the transmission efficiency, and the pitch can be set to 0.5 mm to realize fine adjustment.

[0040] In some optional embodiments, referring to Figures 1 to 3 As shown in the figure, the embodiment of the application provides an axial flux motor high-precision trial-manufacturing and assembly machine, the support seat 3 is provided with an avoidance groove 31 for avoiding the rotor, and two semicircular grooves 32 are arranged on both sides of the avoidance groove 31 and used for supporting the rotor shaft rod.

[0041] The support seat 3 of the embodiment of the application realizes the stable support and space avoidance functions of the rotor subassembly through the combined design of the avoidance groove 31 and the semicircular groove 32. The avoidance groove 31 avoids the rotor core coil part, so that the support is not affected by structural interference, and the semicircular groove 32 forms a two-end support structure by matching the arc surface of the rotor shaft rod, so as to ensure the subsequent axial clamping accuracy.

[0042] When the support seat 3 is in the high position, the avoidance groove 31 provides sufficient placement space for the rotor placement, and cooperates with the pre-positioning action of the semicircular groove 32 to shorten the initial centering time of the rotor shaft rod by 30%, and through the linkage control of the lifting movement of the support seat 3 and the clamping action of the top axis 5, it is ensured that the rotor subassembly is always in the best positioning plane during the axial assembly, so that the assembly coaxiality error is controlled within ±0.03 mm.

[0043] Exemplarily, two semicircular grooves 32 are arranged on both sides of the avoidance groove 31, and the groove bottom is inlaid with a polyurethane buffer pad. The lifting mechanism of the support seat 3 adopts double electric cylinders for synchronous driving, and the lifting speed can be adjusted through a PLC system. When a signal that the top shaft 5 is clamped is detected, the electric cylinder drives the support seat 3 to descend to the avoidance position at a speed of 0.5 mm / s.

[0044] In some optional embodiments, referring to Figures 1 to 3 As shown in the figure, the embodiment of the present application provides an axial flux motor high-precision trial-manufacturing and assembling machine. The support seat 3 of the axial flux motor high-precision trial-manufacturing and assembling machine is vertically and slidingly connected to the workbench 100. The jacking member is arranged in the workbench 100. The support seat 3 is driven by the jacking member to extend out of or be retracted into the workbench 100.

[0045] The support seat 3 of the embodiment of the present application realizes maximization of space utilization through a vertical sliding structure. The jacking member is built-in in the workbench 100 to form a closed driving system, effectively avoiding interference of external mechanical structures on the assembly path.

[0046] When the support seat 3 extends out of the workbench 100 in the vertical direction, the top surface thereof can support the rotor shaft, ensuring initial positioning accuracy when the rotor subassembly is placed. When the support seat 3 is retracted into the workbench 100, the sliding guide eliminates shaking, ensuring perpendicularity of the support seat 3 and the surface of the workbench 100.

[0047] Exemplarily, the support seat 3 is slidingly matched with the sliding hole opened on the top surface of the workbench 100. The jacking member adopts an electric lifting cylinder. After the rotor subassembly is placed in position, the jacking member jacks up the support seat 3 to the positioning height, facilitating positioning by the top shaft 5.

[0048] In some optional embodiments, referring to Figures 1 to 3 As shown in the figure, the embodiment of the present application provides an axial flux motor high-precision trial-manufacturing and assembling machine. The support seat 3 of the axial flux motor high-precision trial-manufacturing and assembling machine is vertically and slidingly connected to the workbench 100. The jacking member is arranged in the workbench 100. The support seat 3 is driven by the jacking member to extend out of or be retracted into the workbench 100.

[0049] The rotating disc 7 of the embodiment of the present application realizes circumferential alignment of the stator and the shell subassembly through rotating adjustment function. The mounting hole on the rotating disc 7 mounts the stator and the shell subassembly through fasteners. The two stator and shell subassemblies can be circumferentially aligned through rotation of the rotating disc 7, improving assembly efficiency.

[0050] The structure design enables the stator and the shell subassembly to be circumferentially pre-aligned while moving axially, which can improve assembly efficiency by 40%. Through the rotating pair design of the rotating disc 7 and the mounting rack 1, assembly stress caused by misalignment of hole positions when the fasteners are locked can be eliminated, significantly reducing the butt joint error of the motor shell sealing surface.

[0051] In some optional embodiments, referring toFigures 1 to 3 As shown in the figure, the axial flux motor high-precision trial-manufacturing and assembling machine is characterized in that the rotating disc 7 is rotatably connected to the mounting frame 1 through the hollow shaft 8, and the top shaft 5 penetrates the mounting frame 1, the hollow shaft 8 and the rotating disc 7 in sequence.

[0052] The coaxial fixing design of the rotating disc 7 and the hollow shaft 8 provides a penetration channel for the top shaft 5 through the hollow structure of the hollow shaft 8, so that the rotating disc 7 can rotate around the top shaft 5. The rotating disc 7 is annular, one end of the hollow shaft 8 is rotatably connected to the mounting frame 1 through a bearing, and the other end is fixedly connected to the rotating disc 7 through a fastener.

[0053] In some optional embodiments, refer to Figures 1 to 3 As shown in the figure, the axial flux motor high-precision trial-manufacturing and assembling machine is characterized in that the workbench 100 is provided with two parallel fixed guide rails 9, and the mounting frame 1 is slidably connected to the two fixed guide rails 9.

[0054] In the embodiment of the application, the two fixed guide rails 9 improve the displacement precision of the mounting frame 1, the bottom surface of the mounting frame 1 is fixedly connected to the sliding block through a fastener, and the sliding block is slidably connected to the fixed guide rail 9.

[0055] In some optional embodiments, refer to Figures 1 to 3 As shown in the figure, the axial flux motor high-precision trial-manufacturing and assembling machine is characterized in that the number of the driving assembly 2 is two, the workbench 100 is provided with a strip-shaped hole 10, the strip-shaped hole 10 is slidably connected to a connecting frame 11, and the two ends of the connecting frame 11 are respectively connected to the mounting frame 1 and the driving assembly 2.

[0056] In the embodiment of the application, the two fixed guide rails 9 improve the straightness precision of the mounting frame 1 when moving in the axial direction. For example, the fixed guide rail 9 is fixed to the top surface of the workbench 100 through a screw, the bottom surface of the mounting frame 1 is fixedly connected to the sliding block through a screw, the sliding block and the fixed guide rail 9 form a sliding pair, the strip-shaped hole 10 restricts the movement stroke of the connecting frame 11, and the driving assembly 2 can adopt an electric sliding table to drive the mounting frame 1 to move through the connecting frame 11.

[0057] The design eliminates the deflection caused by the single-side stress of the mounting frame 1 through the double-rail guide system, and in combination with the electric sliding table driven by the servo motor, the repeated positioning precision of the mounting frame 1 can be improved to 5 times of that of the traditional single-rail structure, and the assembly error caused by the movement shaking is significantly reduced.

[0058] In some optional embodiments, refer to Figures 1 to 3 Figures 1 to 3As shown, this application embodiment provides a high-precision prototype assembly machine for an axial flux motor. The drive assembly 2 of the high-precision prototype assembly machine for an axial flux motor includes a lead screw 21 fixed on a worktable 100, and a housing 22 axially slidably connected to the lead screw 21 and used to drive the mounting frame 1 to move. A nut sleeve threadedly connected to the lead screw 21 is rotatably connected inside the housing 22, and a drive member 23 is used to drive the nut sleeve to rotate around the lead screw 21.

[0059] In this embodiment, the drive assembly 2 achieves axial displacement control of the mounting frame 1 through the precise cooperation between the lead screw 21 and the nut sleeve. The lead screw 21 is fixed on the worktable 100 to form a linear motion reference. The housing 22 is fixedly connected to the mounting frame 1 through the connecting frame 11. The drive component 23 drives the housing 22 to move axially along the lead screw 21 by rotating the nut sleeve, thereby driving the mounting frame 1 to move closer to or away from the intermediate rotor sub-assembly.

[0060] For example, the surface of the nut sleeve can be machined to form a worm gear groove. The drive component 23 uses a motor and drives the nut sleeve to rotate through the meshing of the worm and the worm gear groove. The self-locking characteristic of the worm gear transmission ensures that the mounting bracket 1 maintains its positioning accuracy when the power is off.

[0061] The other end of the worm can extend through the housing 22 and a handle can be installed thereon, allowing the worm to be driven by the handle to fine-tune the position of the mounting bracket 1 in the event of a power outage. In some other embodiments, the meshing structure between the worm and the worm wheel groove can be replaced by a pair of meshing helical gears.

[0062] It should be noted that the role of the drive component 2 in this application is to drive the mounting bracket 1 to move in a straight line. Therefore, it is understood that other drive components 2 that can achieve this function can be used in this application. Those skilled in the art can make adaptive adjustments to the size, shape and material of the drive component 2 according to the usage scenario and test conditions.
