Description

Technical Field

[0001] The utility model belongs to the technical field of motor assembly, and particularly relates to a positioning and clamping tool for motor assembly. Background Technique

[0002] Motor assembly refers to the process of assembling various components together to build a complete motor system. This process usually includes correctly assembling various components such as stators, rotors, coils, bearings, end covers, etc. according to design requirements to form a fully functional motor. Motor assembly needs to strictly follow design specifications and assembly processes to ensure that the performance and quality of the motor meet the requirements. Through motor assembly, various types and specifications of motors can be produced for various different application fields. Currently, in the process of motor assembly, the motor housing is an important part. During motor assembly, it is necessary to position the motor housing. After positioning, the various components that make up the motor are installed inside the housing.

[0003] A Chinese patent with the publication number "CN214380546U" discloses a motor assembly positioning tool, which includes a base. A load-bearing column is installed on the base, and an assembly plate is installed at the upper end of the load-bearing column. An opening is provided on the assembly plate, and an assembly groove is provided on the load-bearing column directly below the opening. A support mechanism is provided in the assembly groove. The upper end of the support mechanism passes through the opening and is installed with a positioning plate. A positioning groove is provided at the middle position of the positioning plate. Load-bearing plates are installed on the assembly plate on both the left and right sides of the positioning plate. A clamping assembly is provided on the side of the load-bearing plate close to the positioning plate. This kind of motor assembly positioning tool clamps the motor housing through the provided clamping assembly, and the clamping assembly is rotationally connected to the threaded rod through a bearing. That is, during assembly, the operator can rotate the motor housing at any time, so that when assembling other parts, it is not necessary to disassemble and reassemble, and different assembly requirements can be met, thereby improving the assembly efficiency.

[0004] During the use of the above device, its overall positioning and assembly is carried out by twisting bolts for positioning. Obviously, during positioning, it is necessary to adjust two groups of bolts simultaneously to achieve centering clamping and positioning. It can be seen that its manual operation is relatively cumbersome, and at the same time, positioning deviation is likely to occur, which is not convenient for quick centering positioning and clamping inside the chassis. Moreover, the structures such as the housing and the rotor inside the motor are mostly circular or arc-shaped, and the above device uses flat clamping plates to assist in positioning and clamping. Due to the unstable characteristics of circular or arc-shaped shapes, it can be seen that its overall clamping stability is poor. Therefore, it needs to be improved. Content of the Utility Model

[0005] Aiming at the problems mentioned in the background technique, the purpose of the utility model is to provide a positioning and clamping tool for motor assembly to solve the problems put forward in the background technique.

[0006] The above technical object of the utility model is achieved by the following technical solutions:

[0008] The clamping device includes a side rail frame fixedly installed on one side of the top seat. A lead screw is rotatably connected inside the side rail frame. The thread directions at both ends of the lead screw are opposite. Both ends of the lead screw are threadedly connected with sliders.

By setting the clamping device, during the use of the device, the rotation of the crank can be adjusted, and the rotation of the lead screw can be assisted by the rotation of the crank. By rotating the lead screw, the sliders can be flexibly adjusted to drive the clamping assembly to displace relative to each other. By the relative displacement of the clamping assembly, the motor housing can be stably centered and clamped, which can improve the stability of the clamping and positioning of the device, making the overall stability of the device stronger and more convenient during use.

[0009] As a preferred technical solution, the clamping assembly includes a bracket fixedly installed on the top of the slider. A fixing plate is fixedly installed at the end of the bracket. A clamping frame is fixedly installed inside the fixing plate. By setting the clamping assembly, during the use of the device, the motor housing can be assisted to be clamped and fixed by the clamping frame inside the fixing plate, which can improve the overall stability of the motor housing.

[0010] As a preferred technical solution, a concave frame is fixedly installed on the outer side of the clamping frame. Limiting springs are fixedly installed at equal intervals inside the concave frame. A clamping plate is fixedly installed at the end of the limiting spring. The inner sides of the clamping plates are fixedly connected with anti-slip protrusions at equal intervals. By setting the limiting springs inside the concave frame, the motor housing can be clamped by the resetting and abutting of the limiting springs against the clamping plates, which can improve the stability after clamping the motor housing, and its elastic setting can avoid damaging the housing and rotor and other structures of the motor during assembly, and can improve the overall stability of the device.

[0011] As a preferred technical solution, support rods are fixedly installed at equal intervals on the outer side of the clamping plate.

[0012] As a preferred technical solution, the overall cross-sectional shape of the clamping frame is V-shaped, and the two groups of clamping plates are arranged in an outward-facing "X" shape. By setting up the V-shaped clamping frame, the V-shaped clamping frame can assist in contacting the arc-shaped motor housing during use, thereby improving the stability of the overall clamping and positioning of the motor housing.

[0013] As a preferred technical solution, the magnetic suction component includes a top plate, which is fixedly installed on the top of the electric push rod. An electromagnet is fixedly installed in the middle of the top of the top plate. Ball bearings are connected to the top of the top plate in a circular shape and rotate at equal intervals. By setting the electromagnet on the top plate, the motor housing can be adsorbed by the electromagnet on the top plate during use, thereby improving the stability of the overall positioning of the motor housing.

[0014] As a preferred technical solution, a fixing frame is fixedly installed on the outer side of the mounting seat, a tool box is fixedly installed on the outer side of the fixing frame, and tool drawers are movably installed at equal intervals on the inner side of the tool box.

[0015] In summary, the utility model mainly has the following beneficial effects:

[0016] First, the operation of the electromagnet generates a magnetic attraction, and then the motor housing can be adsorbed by the electromagnet. At this time, the crank is pulled to drive the screw to rotate, and the slider can be driven to slide against each other inside the side rail frame by rotating the screw. The screw thread is rotated in opposite directions, and the two sets of clamping frames can be caused to move synchronously with each other. The clamping frames are synchronously positioned with each other, which can assist in centering the motor housing. The clamping frames contact the two sides of the motor housing with each other. At this time, the motor housing moves on the top of the top plate through the ball bearing, and the position of the motor housing can be corrected during the clamping period, realizing the center clamping function, which is convenient for fast, stable and accurate assembly of the motor, and can improve the convenience of the overall motor assembly of this device, and can improve the overall performance of this device;

[0017] Secondly, during clamping, the telescopic spring is used to reset the contact clamping plate to contact the motor housing. The anti-slip protrusions on the inner side of the clamping plate can improve the stability of the clamped motor housing. At the same time, the V-shaped clamping frame and the two sets of clamping plates arranged in an outward eight-shaped shape can contact the circular or arc-shaped outer surface of the motor housing through the inner inclined surface, and can squeeze and limit the motor housing. It can flexibly adapt to motors of different sizes and specifications, and can improve the overall adaptability of the device. BRIEF DESCRIPTION OF THE DRAWINGS
