Description

Technical Field

[0001] This article belongs to the technical field of the assembly of motor rotor magnetic tiles, and specifically relates to an assembly tooling for motor rotor magnetic tiles. Background Technique

[0002] In today's automotive industry, with the rapid rise of new energy vehicles, the market for new energy vehicles is expanding day by day, and the demand for new energy vehicles is increasing day by day. The quality and stability of the motor, which is a core functional component of new energy vehicles, determine the stability of the power control and the guarantee of safe driving for each new energy vehicle.

[0003] Currently, in the automatic production line for assembling motor rotors, from the feeding of the motor housing, the feeding of the magnetic tiles, the gluing of the magnetic tiles to the assembly of the motor housing and the magnetic tiles, independent tooling fixtures are used for each process. When the motor rotor is transferred between different processes, due to the change of the clamping and fixing tooling, the assembly dimensional error of the motor rotor becomes larger, and the quality and performance are unstable.

[0004] The quality and performance problems of the motor will be transmitted and affect the safety performance of the whole vehicle, resulting in traffic accidents and endangering the lives of vehicle occupants. During the assembly of the motor rotor, the magnetic tiles and the motor housing are clamped by the manipulator fixture. After the magnetic tiles are glued, the motor housing and the magnetic tiles are assembled. Each process has an independent manipulator and clamping tooling, and the positioning methods of each tooling are different, and there are deviations in both repeatability and reproducibility. The existing process cannot meet the high-precision requirements of the motor.

[0005] In the prior art, the patent name: A fixture structure suitable for magnetic tile assembly, patent number: CN205992843U, provides a fixture structure suitable for magnetic tile assembly, which enables the magnetic tiles and the motor housing to be automatically assembled on the production line. The whole assembly process is fast and convenient, ensuring the efficient and precise production of the whole production line, and the quality of the produced products is good. It includes an upper fixture and a lower fixture. The lower fixture includes a base, an upper positioning structure, and a central positioning shaft. The central positioning shaft protrudes above the base. The upper part of the central positioning shaft is an arc transition structure that tapers upward. The upper positioning structure includes several arc-shaped magnetic tile positioning blocks. The magnetic tile positioning blocks are combined to form a circular structure. A magnetic tile positioning spacer is arranged between adjacent magnetic tile positioning blocks. The inner end of the bottom of each magnetic tile positioning block is provided with a guide wheel. The inner end of each guide wheel is closely attached to the outer end face of the arc transition structure of the central positioning shaft. One end of the corresponding first guide spring is closely attached to the outer side of the bottom of each magnetic tile positioning block.

[0006] In the prior art, two complex dedicated housing jigs and magnetic tile jigs are used in cooperation to achieve the mating magnetic tile assembly with upper and lower overlapping pressing. However, such a form results in an overly complex nested structure and extremely high dimensional accuracy requirements for mutual cooperation, making it impossible to simply and efficiently utilize it on an automated robotic arm production line. It requires complex debugging and adaptation, with extremely high installation and maintenance costs. Moreover, it also requires the housing and magnetic tiles to be clamped and installed almost in a nested manner, resulting in extremely high dimensional requirements for the housing and magnetic tiles, a small acceptable tolerance response, and easily causing the automated production line to malfunction and stop. Summary of the Invention

[0007] To solve the above problems, this article proposes an assembly tooling for the magnetic tiles of an electric motor rotor. The assembly tooling includes a base tooling and a moving jig tooling. The upper surface of the base tooling is fixedly arranged upward, and the moving jig tooling is axially connected to the robotic arm. Above the base tooling, a housing is fixedly arranged. Inside the housing, the moving jig tooling is vertically inserted. A number of magnetic tiles are magnetically adsorbed and fixed around the outside of the moving jig tooling, and the outer surface of the magnetic tiles is adhesively connected to the inner surface of the housing. The base tooling includes a central fixed column, positioning columns, support columns, and a base plate. A central fixed column is vertically and perpendicularly arranged at the center of the base plate. Positioning columns are arranged outside the central fixed column. A number of support columns are arranged in an annular array outside the central fixed column. The lower outer sides of the central fixed column, positioning columns, and support columns are vertically inserted outside the bottom plate of the housing. The upper outer sides of the central fixed column and positioning columns are inserted with the moving jig tooling. The moving jig tooling includes a tooling frame, a downward pressing push block, an assembly fixing seat, outer clamping columns, a pushing slider, and a pushing ball. Outer clamping columns are arranged at equal intervals in a ring outside the tooling frame. An assembly fixing seat is arranged outside the upper end of the tooling frame. A downward pressing push block is arranged to move up and down inside the tooling frame. The center of the downward pressing push block is penetrated outside the central fixed column. A return spring is arranged between the bottom surface of the downward pressing push block and the inner bottom surface of the tooling frame. A number of pushing sliders are arranged in an annular slope outside the downward pressing push block. The pushing sliders are all arranged at equal intervals in the middle between the outer clamping columns. A pushing ball is embedded on the outer surface of the pushing slider. A return spring is arranged between the upper outer side of the pushing slider and the upper inner part of the tooling frame. The outer surface of the pushing ball magnetically adsorbs the magnetic tile, and the magnetic tile is clamped between the outer clamping columns. Using the assembly tooling for fixed nesting of the housing and magnetic tiles avoids errors caused by the alternating replacement and use of multiple toolings. From feeding to assembly of the electric motor rotor, a set of tooling is used, which improves the dimensional accuracy of the electric motor rotor and the production stability, and reduces the cost of manufacturing a production line with multiple toolings and combined equipment.

[0008] The shape of the substrate is a horizontal rectangular plate. Seat handles are longitudinally provided at both ends of the upper surface of the substrate. A central fixing column is vertically fixed at the center of the substrate. Positioning columns are obliquely and equidistantly arranged adjacent to the left and right sides of the outside of the central fixing column. The height of the positioning column is less than the sum of the thickness of the casing and the bottom surface thickness of the tooling frame. The fixed substrate is used for reference-type fixed connection, so as to ensure that the casing can be stably fixed above the substrate. At the same time, the central fixing column, the positioning column and the support column can accurately position the casing and ensure firm fixation to prevent displacement. Among them, the central fixing column can also play a role in plugging and fixing the moving jig tooling.

[0009] The support columns are arranged in a two-by-two annular array on the outside of the central fixing column. Each group of support columns is arranged between the outer clamping columns. The center points of the distances between each group of support columns are aligned with the center points of the distances between the outer clamping columns. The upper ends of the support columns are in mutual contact and connection with the bottom side surface of the magnetic tile. The support columns are used to assist in supporting the magnetic tile from the bottom when it is pushed, so as to ensure the stable support of the magnetic tile during the pressing process.

[0010] The shape of the casing is a circular disc-shaped shell. A plug hole protrudes from the center of the bottom surface of the casing. Positioning holes are annularly and equidistantly arranged outside the plug hole. A number of through holes are arranged in an annular array outside the plug hole. The central fixing column is arranged inside the plug hole. The positioning column is arranged inside the positioning hole. The support column is arranged inside the through hole. By inserting the disc-shaped casing with the opening facing up above the substrate, it is possible to achieve convenient direct up-and-down direct assembly, which is convenient for the loading and unloading of automated equipment.

[0011] The shape of the magnetic tile is a strip-shaped arc-shaped tile. An arc surface is provided on one side surface of the magnetic tile. The other side surface of the magnetic tile is a parallel surface. Horizontal surfaces are provided at both ends of the magnetic tile in a parallel manner. The parallel surface of the magnetic tile is magnetically fixed with the pushing ball. The two end surfaces of the magnetic tile are connected to the side surfaces of the outer clamping columns in a clamping manner. The radian of the arc surface is the same as the inner radian of the casing. A general magnetic tile is used. The outer surface of the magnetic tile is fixed in an adhesive form, while the inner parallel surface is convenient for pre-magnetic adsorption clamping and post-pushing fixation.

[0012] The tooling frame is in the shape of a circular shell, and the outer arc surface of the tooling frame is vertically provided with an outer clamping column, and the top surface of the tooling frame is provided with a longitudinally spanning assembly fixing seat, and the center of the top surface of the tooling frame is vertically provided with a vertical sliding hole, and the outer arc surface of the tooling frame is provided with a horizontal sliding groove between the outer clamping columns, and the center of the bottom surface of the tooling frame is provided with a plug-in hole, the outer side of the plug-in hole is provided with a positioning hole, the inner side of the vertical sliding hole is slidably plugged in and provided with a downward push block, and the inner side of the horizontal sliding groove is slidably plugged in and provided with a pushing slider, the inner side of the plug-in hole is provided with a central fixing column, and the inner side of the positioning hole is provided with a positioning column. Through the circular tooling frame, the overall mobile fixture tooling can be conveniently moved down to the interior of the casing, and the magnetic tiles can also be placed equidistantly in a ring, which is convenient for the magnetic suction clamping of the magnetic tiles, and it is also convenient to arrange the pushing slider in a ring.

[0013] The assembly fixing seat is in the shape of a cross-type bridge seat, and rotating shaft seats are horizontally provided in the centers of both sides of the assembly fixing seat, and the upper end of a downward push block is penetrated by the central surface of the assembly fixing seat. The assembly fixing seat and the rotating shaft seat are both axially fixedly connected to the robot arm, and a pneumatic push rod is provided in the center of the robot arm, and the pneumatic push rod of the robot arm is fitted and connected to the top end surface of the downward push block. Through the assembly fixing seat, the entire mobile fixture tooling can be conveniently axially rotatably arranged on the robot arm, and the downward push block protruding above the assembly fixing seat can also be conveniently used for direct linkage control using the robot arm linkage.

[0014] The shape of the downward pressure push block is a circular column, and a guide sliding plate is provided at the lower end of the downward pressure push block, a conical block which is wide at the top and narrow at the bottom is provided in the middle of the downward pressure push block, and a downward pressure guide column is provided at the upper end of the downward pressure push block, the guide sliding plate is arranged inside the bottom surface of the pushing slider, the outer side of the conical block is fitted and connected with the inner end surface of the pushing slider, and the downward pressure guide column vertically penetrates and protrudes from the upper surface of the assembly fixing seat, and a plug hole is provided at the center of the lower end surface of the pressing push block, a spring hole is provided on the outer side of the plug hole, a central fixing column is provided on the inner side of the plug hole, and a return spring is provided on the inner side of the spring hole. When the downward pressure push block is pushed downward, the annular pushing slider is pushed outward, so that the magnetic tile arranged on the outer side of the pushing slider can be tightly fitted with the casing, thereby facilitating the bonding effect of the magnetic tile, and can also be conveniently recovered through the return spring to achieve a self-resetting effect.

[0015] The push slider is in the shape of a rectangular block, and the push slider is embedded and slidably arranged inside the tooling frame. A pushing ball is embedded in the outer end surface of the pushing slider, and an upper and lower sliding groove is arranged at the bottom of the inner end of the pushing slider. A pushing protrusion is protruding on the upper inner end of the pushing slider, and the outer surface of the pushing protrusion is connected to the tooling frame through a return spring, and the inner surface of the pushing protrusion is provided with a pushing slope surface which is wide at the top and narrow at the bottom. The pushing slope surface is closely connected with the downward push block, and a magnet is embedded in the outer surface of the tooling frame outside the two ends of the outer surface of the pushing slider, and a pushing ball is retracted and moved. A pushing spring is arranged on the inner side of the pushing ball, and through the pushing slider arranged in a ring between the outer clamping columns, each magnetic tile can be pushed independently, and the pushing ball can not only achieve magnetic suction clamping, but also have a flexible pushing effect on the rolling type, to prevent the magnetic tile from being damaged during the hard pushing process. Beneficial Effects

[0016] The use of fixed assembly tools that are nested with the casing and magnetic tiles avoids errors caused by the alternating use of multiple tools. The use of a set of tools from loading to assembling the motor rotor improves the dimensional accuracy of the motor rotor and the stability of production, and reduces the cost of production lines with multiple tools and combined equipment.

[0017] A fixed base plate is used for reference type fixed connection to ensure that the casing can be stably fixed on the base plate, and the central fixed column, positioning column and support column 1 can be used to accurately position the casing while ensuring that it is firmly fixed to prevent displacement. The central fixed column can also serve to plug and fix the mobile fixture.

[0018] The support columns are used to assist in supporting the magnetic tiles from the bottom when pushing, thereby ensuring stable support of the magnetic tiles during the pressing process.

[0019] By inserting the disc-type casing with the opening facing upward onto the top of the base plate, it is possible to conveniently assemble directly up and down, thereby facilitating the loading and unloading of automated equipment.

[0020] Universal magnetic tiles are used, and the outer surface of the magnetic tiles is fixed by gluing, while the inner parallel surface is convenient for early magnetic clamping and later push fixation.

[0021] The circular tooling frame makes it easy to move the entire mobile fixture tooling down to the inside of the casing, and can also place the magnetic tiles equidistantly in a circle, which is convenient for magnetic attraction and clamping of the magnetic tiles, and can also facilitate the arrangement of the push slider in a circle.

[0022] By assembling the fixing base, the entire mobile fixture tooling can be conveniently and axially rotatably arranged on the robotic arm, and it is also possible to conveniently use the robotic arm to link and control the downward pressing push block protruding above the assembling fixing base directly.

[0023] When the downward pressing push block moves downward to push, the annularly arranged pressing slider is pushed outwards, so that the magnetic tile arranged on the outside of the pressing slider can be firmly adhered to the machine shell, facilitating the adhesive effect of the magnetic tile, and it is also possible to conveniently recycle through the return spring to achieve the self-resetting effect.

[0024] Through the pressing slider arranged annularly between the outer clamping columns, each magnetic tile can be conveniently pushed independently. The pressing ball can not only achieve magnetic absorption and clamping, but also play a flexible pressing effect for rolling, preventing damage to the magnetic tile during the hard pressing process.

[0035] Implementation example;

[0041] The base tooling 1 is fixed at the fixed position of the automatic line process.
