[0002] A transformer is an electrical device used to change the voltage of alternating current in a power system. It mainly consists of two or more windings and an iron core. During the transformer manufacturing process, fixtures are required to fix and support different components.

[0003] For example, publication number CN213340059U discloses a fixture for transformer production, including a mounting plate, a transformer bracket and an apron bracket arranged opposite to the mounting plate, a transformer mounting seat and an apron mounting seat for mounting the transformer bracket and the apron bracket, a transformer shaft rotatably connected to the transformer bracket, one end of the transformer shaft extends to one side of the transformer bracket to drive the connection gluing mechanism, and the apron bracket is rotatably connected to the apron shaft.

[0004] However, in the prior art, when clamping transformer components, some of the components are made of brittle materials, and the power source of the clamp is usually a push rod type structure such as an electric cylinder or a hydraulic cylinder. This type of structure is characterized by high force and therefore does not have the function of protecting brittle materials. During use, excessive clamping force may cause the components to deform or break, and once the components are deformed or broken, they cannot be used normally. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the power source of the clamp in the prior art is usually a push rod structure of an electric cylinder or a hydraulic cylinder. This type of structure is characterized by large force and therefore has no protection for brittle materials. A clamp for transformer production is proposed.

[0006] In order to achieve the above-mentioned object, the utility model adopts the following technical solution: a clamp for transformer production, comprising a bearing assembly and a clamping assembly, wherein the clamping assembly is movably mounted on the top of the bearing assembly, a reduction motor is provided at the bottom of the bearing assembly, the clamping assembly comprises a positioning block, a first movable block and a second movable block, the first movable block is slidably connected to one side of the positioning block, the second movable block is slidably connected to one side of the first movable block, and a groove is provided on one side of the second movable block;

[0007] The bearing assembly includes a support platform, a turntable and a transmission rod. One side of the support platform is fixedly connected to one side of the reduction motor. The turntable is rotatably mounted on the outer wall of the support platform. One side of the turntable is meshed with a transmission gear, and the transmission gear is fixedly mounted on the output end of the reduction motor. An extension rod is fixedly mounted on the lower surface of the turntable. One end of the transmission rod is rotatably connected to the outer wall of the extension rod, and the other end of the transmission rod is rotatably connected to the bottom of the clamping assembly.

[0008] Preferably, an anti-slip plate is fixedly mounted on the bottom of the positioning block, and the first movable block and the second movable block are both slidably connected to the upper surface of the anti-slip plate.

[0009] Preferably, a connecting block is fixedly installed on the top of the support platform, and the turntable is located at the junction of the support platform and the connecting block.

[0010] Preferably, a guide rod is fixedly connected to the interior of the connecting block, and a limiting convex strip is fixedly installed on the bottom of the guide rod.

[0011] Preferably, support plates are fixedly mounted on both ends of the guide rod, and the support plates are located on one side of the anti-slip plate.

[0012] Preferably, a slider is fixedly mounted on the lower surface of the anti-slip plate, and the slider is slidably connected to the outer wall of the guide rod.

[0013] Preferably, a vertical rod is fixedly installed on the bottom of the anti-slip plate, the vertical rod is rotatably connected to the transmission rod, and a limiting ring is fixedly installed at the intersection of the vertical rod and the transmission rod.

[0014] Compared with the prior art, the advantages and positive effects of the present invention are:

[0015] 1. In the utility model, a turntable and a transmission rod are provided to drive the clamping assembly. When in use, a pushing structure such as an electric cylinder is not used, which can avoid the problem of excessive clamping force. When the turntable rotates, the transmission rod drives the clamping assembly to clamp the transformer parts, which can protect brittle materials. In addition, the first movable block and the second movable block in the clamping assembly can move within a small range and can adapt to transformer parts of different sizes and shapes.

[0016] 2. In the present invention, the turntable is driven by a transmission gear, and the diameter of the transmission gear is much smaller than the diameter of the turntable. Therefore, the transmission gear needs to rotate many times to push the turntable to rotate the required angle. This method can accurately control the clamping force of the clamping assembly, and the coordinated use of the guide rod and the slider can improve the stability of the clamping assembly.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] The following is a detailed description of the specific settings and functions of this embodiment. When in use, the clamping assembly 2 is used to clamp and fix the parts of the transformer. The clamping assembly 2 is controlled by the carrying assembly 1. The reduction motor 3 drives the transmission gear 18 to push the turntable 14. During the rotation of the turntable 14, the transmission rod 17 is driven by the extension rod 16. The transmission rod 17 pulls the two clamping assemblies 2 closer to each other to complete the clamping of the transformer parts. The two support plates 11 are used to determine the initial position of the slider 26. The guide rod 12 is installed in the connecting block 13 and is connected to the two support plates 11.

[0026] The turntable 14 is rotatably mounted on a support platform 15, which supports the turntable 14 and determines the center of rotation of the turntable 14. The reduction motor 3 is mounted on the side of the support platform 15 and has good stability. The diameter of the transmission gear 18 is much smaller than the diameter of the turntable 14. Therefore, the transmission gear 18 needs to rotate many times to push the turntable 14 to rotate the required angle. By determining the number of rotations of the transmission gear 18, the clamping force can be accurately controlled.

[0027] Example 2: Figure 2 and Figure 3As shown, the clamping assembly 2 includes a positioning block 21, a first movable block 22 and a second movable block 23. The first movable block 22 is slidably connected to one side of the positioning block 21, and the second movable block 23 is slidably connected to one side of the first movable block 22. A groove 24 is provided on one side of the second movable block 23. An anti-slip plate 25 is fixedly installed at the bottom of the positioning block 21. The first movable block 22 and the second movable block 23 are both slidably connected to the upper surface of the anti-slip plate 25. The support plate 11 is located on one side of the anti-slip plate 25. A slider 26 is fixedly installed on the lower surface of the anti-slip plate 25. The slider 26 is slidably connected to the outer wall of the guide rod 12. A vertical rod 27 is fixedly installed at the bottom of the anti-slip plate 25. The vertical rod 27 is rotatably connected to the transmission rod 17. A limiting ring 28 is fixedly installed at the intersection of the vertical rod 27 and the transmission rod 17.

[0028] The effect achieved by the entire embodiment is that when the clamping assembly 2 contacts the transformer parts, the resistance of the parts will force the first movable block 22 and the second movable block 23 to move, and the first movable block 22 moves on the positioning block 21, and the second movable block 23 moves on the first movable block 22, so as to ensure that the first movable block 22 and the second movable block 23 can adapt to the shape of the parts, and the presence of the groove 24 can improve the friction coefficient and prevent the problem of slipping. The bottom of the positioning block 21 is provided with an anti-slip plate 25, and the anti-slip plate 25 mainly prevents the first movable block 22 and the second movable block 23 from detaching from the positioning block 21 through the groove on its upper surface. The slider 26 at the bottom of the anti-slip plate 25 is slidably connected to the guide rod 12, and the bottom of the guide rod 12 is provided with a limited ridge 19 to ensure that the slider 26 does not rotate;

[0029] The transmission rod 17 pulls the slider 26 through the vertical rod 27 to drive the anti-slip plate 25. A limit ring 28 is provided at the intersection of the vertical rod 27 and the transmission rod 17 to prevent the transmission rod 17 from separating from the vertical rod 27.

[0030] The device is used to clamp and fix the transformer components. The components to be clamped are placed on the connecting block 13. The reduction motor 3 is then started. The reduction motor 3 drives the transmission gear 18 to push the turntable 14. During the rotation of the turntable 14, the transmission rod 17 is driven by the extension rod 16.

[0031] The transmission rod 17 pulls the slider 26 through the vertical rod 27 to drive the anti-slip plate 25, so that the two clamping components 2 are close to each other to complete the clamping of the transformer components. The resistance of the components will force the first movable block 22 and the second movable block 23 to move. The first movable block 22 moves on the positioning block 21, and the second movable block 23 moves on the first movable block 22 to ensure that the first movable block 22 and the second movable block 23 can adapt to the shape of the components, and the presence of the groove 24 can increase the friction coefficient and prevent slipping.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
