Description

Technical Field

[0001] This utility model relates to the field of motor stator manufacturing technology, and in particular to an auxiliary clamping device for lamination welding of motor stators. Background Technology

[0002] The stator is an important component of motors such as generators and starters. It is a crucial part of the electric motor. The stator consists of three parts: the stator core, the stator windings, and the frame. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by magnetic lines of force within this rotating magnetic field, thereby generating (output) current.

[0003] The stator core is made of stacked silicon steel sheets to reduce hysteresis loss and eddy current loss. During the production process, the silicon steel sheets need to be arranged and then stacked and welded for fixation. In the existing stacking and welding equipment, the bottom of the silicon steel sheets is in direct contact with the clamping equipment, resulting in insufficient space for the welding torch to move, which affects the welding effect of the bottom silicon steel sheets. In addition, it does not have effective limiting, and there is a certain deviation when subjected to pressure from the welding torch. Therefore, it is necessary to provide effective support for the bottom of the silicon steel sheets during clamping, provide sufficient operating space, and effectively prevent the clamped silicon steel sheets from rotating. Utility Model Content

[0004] This utility model addresses the deficiencies in the existing technology by providing an auxiliary clamping device for stacking and welding motor stator laminations.

[0005] This utility model is achieved through the following technical solution:

[0006] An auxiliary clamping device for laminating and welding motor stator laminations includes a clamping table, a limiting mechanism, a driving mechanism, supporting balls, a support ring, a socket, a locking post, a pad, and a pressure ring. The limiting mechanism is disposed on the upper surface of the clamping table, the driving mechanism is disposed on the top of the clamping table, the supporting balls are mounted on the upper surface of the clamping table, the support ring is locked on the top of the driving mechanism, the socket is locked inside the driving mechanism, the locking post is fixedly disposed on the top of the socket, the pad is sleeved on the outside of the locking post, and the pressure ring is disposed on the top of the pad. The driving mechanism includes a driving motor, a rotating disk, and a limiting locking ring. The driving motor is fixed to the bottom of the clamping table, the rotating disk is fixedly disposed at the output end of the driving motor, and the limiting locking ring is fixedly disposed on the top of the rotating disk.

[0007] In a preferred embodiment of the present invention, the limiting mechanism includes a mounting base, a hydraulic cylinder, and a limiting strip. The hydraulic cylinder is mounted on the back of the mounting base, and the limiting strip is fixedly disposed on the telescopic end of the hydraulic cylinder.

[0008] The limiting mechanism effectively limits the silicon steel sheets from the outside after they are stacked and fixed, preventing the clamped silicon steel sheets from rotating.

[0009] In a preferred embodiment of this utility model, a retaining strip is provided on the outer side of the bottom of the socket, and a slot is provided in the middle of the limiting retaining ring to cooperate with the socket and its outer retaining strip;

[0010] The socket is secured inside the limiting ring, and its outer locking strip is secured in the corresponding slot inside the slot, ensuring that the rotation of the drive motor can drive the clamped silicon steel sheet to rotate.

[0011] In a preferred embodiment of this utility model, the supporting ball is installed through a limiting seat at its bottom, and the top of the supporting ball contacts the bottom of the rotating disk;

[0012] The support balls provide effective support at the bottom edge of the rotating disk, preventing excessive pressure from being applied to the output end of the drive motor and ensuring that the rotating disk is in a horizontal position.

[0013] In a preferred embodiment of this utility model, the pressure ring is sleeved on the outside of the locking post, and the top of the pressure ring is higher than the top of the locking post.

[0014] In a preferred embodiment of this utility model, the support ring has a frustum-shaped structure, and its inner side is fitted with the outer side of the limiting ring.

[0015] The beneficial effects of this utility model are:

[0016] This motor stator lamination stacking and welding auxiliary clamping equipment effectively clamps the stator silicon steel sheets and ensures sufficient operating space at the top and bottom for welding, thus ensuring welding quality. It can automatically switch the welding area and limit the silicon steel sheets on the outside during the welding process to prevent the silicon steel sheets from rotating or moving due to stress, thereby ensuring welding quality.

[0022] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. The directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings. Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting this utility model.

[0023] like Figure 1-4 The illustrated auxiliary clamping device for laminating and welding motor stator laminations includes a clamping platform 1, a limiting mechanism 2, a driving mechanism 3, supporting balls 4, a support ring 5, a socket 6, a locking post 7, a pad 8, and a pressure ring 9. The limiting mechanism 2 is disposed on the upper surface of the clamping platform 1, the driving mechanism 3 is disposed on the top of the clamping platform 1, the supporting balls 4 are mounted on the upper surface of the clamping platform 1, the support ring 5 is locked on the top of the driving mechanism 3, the socket 6 is locked inside the driving mechanism 3, the locking post 7 is fixedly disposed on the top of the socket 6, the pad 8 is sleeved on the outside of the locking post 7, and the pressure ring 9 is disposed on the top of the pad 8. The driving mechanism 3 includes a driving motor 31, a rotating disk 32, and a limiting locking ring 33. The driving motor 31 is fixed to the bottom of the clamping platform 1, the rotating disk 32 is fixedly disposed at the output end of the driving motor 31, and the limiting locking ring 33 is fixedly disposed on the top of the rotating disk 32.

[0024] Specifically, the limiting mechanism 2 includes a mounting base 21, a hydraulic cylinder 22, and a limiting insert 23. The hydraulic cylinder 22 is mounted on the back of the mounting base 21, and the limiting insert 23 is fixedly set at the telescopic end of the hydraulic cylinder 22. A retaining strip is provided on the outer side of the bottom of the socket 6. A slot is provided in the middle of the limiting retaining ring 33 to cooperate with the socket 6 and its outer retaining strip. The supporting ball 4 is installed through the limiting retaining seat at its bottom. The top of the supporting ball 4 contacts the bottom of the rotating disk 32. The pressure ring 9 is sleeved on the outer side of the retaining post 7. The top of the pressure ring 9 is higher than the top of the retaining post 7. The support ring 5 has a frustum-shaped structure, and its inner side is in contact with the outer side of the limiting retaining ring 33.

[0025] In this embodiment, the prepared stator lamination is fitted onto the outside of the retaining post 7, with the central hole of the stator lamination matching the outer diameter of the retaining post 7. Then, the socket 6 is fitted into the slot in the middle of the limiting retaining ring 33 according to its outer retaining strip. At this time, the top of the support ring 5 fitted onto the outside of the limiting retaining ring 33 will be in contact with the bottom edge of the bottom stator lamination. The support ring 5 increases the contact area at the bottom of the stator lamination and effectively supports the bottom edge of the stator lamination, thereby reducing the risk of deformation of the lamination under pressure. Similarly, the pad 8 is fitted onto the top of the top stator lamination to effectively increase the contact area, and the pressure ring 9 is placed on top of the pad 8. The pressure ring 9 effectively ensures that when the pressure is applied by the pressure device, it will not directly act on the top of the retaining post 7, and can effectively apply pressure to the top of the stator lamination to achieve effective clamping and fixing.

[0026] Furthermore, the hydraulic cylinder 22 mounted on the back of the mounting base 21 extends, allowing the protruding part on the outer side of the limiting insert 23 to be engaged in the positioning slot on the outer side of the stator lamination. This prevents the stator lamination from being squeezed by the welding torch during welding, thus avoiding rotational displacement. Through the action of the support ring 5 and the pad 8, sufficient space is provided at the top and bottom of the stator lamination to facilitate welding torch operation. After a single weld is completed, the hydraulic cylinder 22 retracts, and the pressure device releases the pressure. At this time, the drive motor 31 rotates at a certain angle to automatically switch the processing area. The support ball 4 set between the rotary table 32 and the clamping table 1 effectively provides support, preventing excessive pressure from acting on the output shaft of the drive motor 31 and ensuring the levelness of the rotary table 32.
