Description

Technical Field

[0001] This utility model relates to the field of stator core processing technology, specifically a stator core clamping device. Background Technology

[0002] The stator is a crucial part of an electric motor. It consists of three parts: the stator core, the stator windings, and the frame. The stator core is a vital component and a major part of the motor's magnetic circuit. The stator windings are the copper wires wound around the stator. During stator core manufacturing, after the windings are wound onto the stator core, insulating strips are pressed into the core to seal the openings in the outer winding slots, thus enhancing the overall insulation. This process of pressing insulating strips into the stator core is also known as stator core fiber insertion.

[0003] For example, the announcement number CN 218613677 U is a clamping device for processing stator cores. The device includes a worktable with a built-in clamping cavity. A driving device is installed in the clamping cavity. The driving device includes a worm gear, a worm, a clamping motor, a fixing plate, a fixing column, and a fixing seat. The main problem it solves is that when the stator core is placed directly on the table, the shaking or sliding of the stator core during the fiber insertion process will affect the fiber insertion effect and thus affect the processing efficiency.

[0004] In the above-mentioned device, two sets of motors drive the surrounding clamps to open and close for clamping and fixing. This method is wasteful of power resources and is also quite complicated. Therefore, we propose a stator core clamping device to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a stator core clamping device to solve the problem in the background art that the above-mentioned device is set up with two sets of motors to drive the surrounding clamps to open and close for clamping and fixing, which is wasteful of power resources and is also quite complicated.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stator core clamping device, including a processing table;

[0007] Also includes:

[0008] A fixed clamp is located at the upper center of the processing table. A movable clamp is located on one side of the upper end of the processing table. Both the movable clamp and the fixed clamp have clamping openings on their inner sides, and the clamping openings are triangular in shape. Fixed blocks are symmetrically arranged on both sides of the movable clamp. A sliding rod is provided at the front end of the fixed block, and the sliding rod extends through both sides of the fixed clamp to the rear of the fixed clamp. A mounting plate is provided at the other end of the sliding rod, and the mounting plate connects and fixes the two sliding rods. The mounting plate is located behind the fixed clamp.

[0009] Preferably, the upper end of the processing table is provided with a first fixing frame and a second fixing frame, and the second fixing frame is located between the fixing clamp and the mounting plate. A screw is provided between the first fixing frame and the second fixing frame. A motor is provided on the outside of the first fixing frame and is connected to the screw. A threaded hole is provided in the middle of the surface of the mounting plate, and the mounting plate is threadedly connected to the screw through the threaded hole.

[0010] Preferably, the fixing clamp has sliders symmetrically arranged on both sides, and the sliders have through holes inside, and the sliders are engaged with the outside of the slide rod through the through holes.

[0011] Preferably, the fixing clamp is fixed above the processing table by a bracket.

[0012] Preferably, the processing table has symmetrically arranged sliding grooves on both sides of its surface, and the sliding grooves are located below the movable clamp. The movable clamp has symmetrically arranged sliding plates on both sides of its bottom, and the sliding plates are slidably engaged inside the sliding grooves.

[0013] Preferably, the inner wall of the clamping opening is provided with an anti-slip pad by adhesive.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) By setting up a movable clamp and a fixed clamp, the movable clamp is moved by using a screw drive, so that only one motor is needed to drive the movement, which can save power resources and reduce costs. The inner sides of the movable clamp and the fixed clamp are provided with triangular clamping holes, which facilitates the clamping of stator cores of different sizes, thus facilitating the assembly of stator cores.

[0016] (2) By setting a slider on the outside of the fixed clamp and setting a fixed block and a sliding rod on the outside of the movable clamp, the stability of the movable clamp movement is improved by connecting the sliding rod with the slider. The sliding rod passes through the fixed clamp and connects to the mounting plate at the rear. The distance between the movable clamp and the fixed clamp is adjusted by using a screw, thereby adjusting the opening and closing distance between the two clamping ports. Anti-slip pads are attached to the surface of the clamping ports to further improve the clamping stability. Attached Figure Description
