Technical Field
[0001] This utility model belongs to the field of transformer technology, specifically a fixed tooling for transformer processing and testing. Background Technology
[0002] Small transformers are characterized by their small size, low cost, and minimal wiring requirements. However, they generally have lower load rates and utilization rates. The inductive loads they carry are typically not capacitively compensated. Small transformers are a common piece of equipment in factory electrical control systems. During manufacturing and testing, they need to be positioned and fixed on the workbench to restrict their multiple orientations. Otherwise, the transformer may shift due to external forces, leading to inaccurate processing and testing. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a fixed tooling for transformer processing and testing, in order to address the above-mentioned deficiencies and solve the problems mentioned in the background art.
[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a fixed fixture for transformer processing and testing includes a workbench and a transformer body. A mounting bracket is provided at the bottom of the transformer body. A first mounting hole is provided on the mounting bracket. A bearing platform is detachably provided at the middle of the upper surface of the workbench.

A connecting bolt threadedly connected to the connecting hole is provided at the top of the positioning post. Through holes are symmetrically provided on both sides of the positioning post at the top of the mounting bracket. A limit block is slidably provided inside the through hole. One side of the limit block extends to the outside of the positioning post, and the other side abuts against the outer surface of the connecting bolt. The bottom end of the limit block outside the positioning post abuts against the upper surface of the mounting bracket. Clamping blocks are symmetrically provided on both sides of the transformer body. A horizontal drive assembly for driving the clamping blocks to move back and forth is provided on the workbench.
[0005] Furthermore, the upper surface of the support platform is flush with the upper surface of the worktable.
[0006] Furthermore, the upper surface of the support platform is uniformly provided with a plurality of second mounting holes, the bottom end of the outer surface of the positioning post is provided with an external thread, and the inner wall of the second mounting hole is provided with an internal thread.
[0007] Furthermore, the top of the connecting bolt is provided with a gripping part, the inner walls of both ends of the through hole are symmetrically provided with first sliding grooves, the two ends of the limiting block are symmetrically provided with first sliding blocks that match the first sliding grooves, and the top of the limiting block near the connecting bolt is provided with a driving inclined surface.
[0008] Furthermore, the horizontal drive assembly includes a guide groove, a dovetail slide, a screw, a motor, a second slider, a dovetail slider, and a connecting block.

[0009] Furthermore, guide rails are provided on the inner walls of both ends of the guide groove, and second slide grooves matching the guide rails are opened at both ends of the second slider.
[0010] The beneficial effects of this utility model are:
[0011] This utility model utilizes a support platform, positioning column, connecting hole, connecting bolt, through hole, limiting block, clamping block, and horizontal drive assembly. When the transformer body is placed on the support platform, the positioning column passes through the first mounting hole of the transformer body, positioning it and limiting it in the horizontal direction. The connecting bolt rotates inward through the connecting hole, driving the limiting block to move outward from the positioning column, so that the bottom end of the limiting block abuts against the upper surface of the mounting bracket. The outer surface of the connecting bolt also limits the limiting block, ensuring it is stably positioned outside the positioning column. This, in turn, limits the vertical direction of the transformer body, preventing it from jumping due to processing forces. The horizontal drive assembly then drives the clamping block closer to the side wall of the transformer body, further clamping and fixing it, ensuring the transformer body is firmly and stably fixed on the worktable, preventing displacement due to external forces and making processing and inspection more accurate.

[0017] The present invention will be further described below with reference to the accompanying drawings.
[0018] Reference Figure 1-3 As shown, the fixed fixture for transformer processing and testing includes a workbench 1 and a transformer body 2. A mounting bracket 3 is provided at the bottom of the transformer body 2. The mounting bracket 3 has four first mounting holes 301. A detachable support platform 4 is provided at the center of the upper surface of the workbench 1. The support platform 4 is fixed to the workbench 1 with bolts. It can be replaced with a support platform having different spacing of second mounting holes 401 to accommodate different transformers, thus satisfying the different spacing of the first mounting holes 301. The upper surface of the workbench 1 has a section that matches the support platform 4. The upper surface of the support platform 4 is flush with the upper surface of the worktable 1, which facilitates the movement of the clamping block to the upper surface of the support platform 4 and forms a clamping and fixing of the transformer body 2. The upper surface of the support platform 4 is detachably provided with positioning posts 5 that match the first mounting holes 301. The mounting bracket 3 is placed on the support platform 4. The top of the positioning post 5 passes through the first mounting hole 301 and extends to the top of the mounting bracket 3. There can be four positioning posts 5, which correspond to the four first mounting holes 301, and firstly limit the transformer body 2, restricting its movement in multiple directions in the horizontal direction on the support platform 4.
[0019] The positioning post 5 has a connecting hole 501 inside. A connecting bolt 6, threadedly connected to the connecting hole 501, is provided at the top of the positioning post 5. A gripping part 601 is provided at the top of the connecting bolt 6. Rotating the gripping part 601 drives the connecting bolt to move up and down along the connecting hole 501. Symmetrically, through holes 502 are provided on both sides of the positioning post 5 at the top of the mounting bracket 3. The through holes 502 communicate with and are perpendicular to the connecting holes 501. A limiting block 503 is slidably installed inside the through hole 502. One side of the limiting block 503 extends to the outside of the positioning post 5, and the other side abuts against the outer surface of the connecting bolt 6. The bottom end of the limiting block 503 outside the positioning post 5 abuts against the upper surface of the mounting bracket 3. First sliding grooves 504 are symmetrically provided on the inner walls of both ends of the through hole 502. First sliding blocks 505, matching the first sliding grooves 504, are symmetrically provided on both ends of the limiting block 503. A driving part is provided at the top of the limiting block 503 near the connecting bolt 6. After the inclined plane 506 and the mounting bracket 3 and the positioning post 5 are engaged, the gripping part 301 is rotated to drive the connecting screw 6 to move downward and abut against the inclined plane 506. This drives the limiting block 503 and the first slider 505 to move outward along the first slide groove 504 and the through hole 502. One side of the bottom of the limiting block 503 abuts against the upper surface of the mounting bracket 3, and the outer surface of the connecting bolt 6 abuts against the other side of the limiting block. This prevents the limiting block 503 from moving towards the end of the connecting hole 501, thus limiting the up and down movement of the mounting bracket 3 and preventing it from jumping due to the force during processing. When it is necessary to remove the transformer body 2, simply rotate the gripping part to move the connecting bolt 6 upward above the through hole 502 and press the limiting block 503 to enter the through hole 502. Then the mounting bracket 3 can be moved upward towards the positioning post 5. The operation is simple, requires no special operating tools, and is convenient to use.
[0020] The transformer body 2 has symmetrical clamping blocks 7 on both sides. A horizontal drive assembly 8, which drives the clamping blocks to reciprocate, is installed on the worktable 1. The horizontal drive assembly 8 includes a guide groove 801, a dovetail slide 802, a screw 803, a motor 804, a second slider 805, a dovetail slider 806, and a connecting block 807. The guide groove 801 is located inside the worktable 1 on one side of the support platform 4. The dovetail slide 802 is located at the top of the guide groove 801 and they are interconnected. The inner diameter of the guide groove 801 is larger than the inner diameter of the dovetail slide 802, making the movement of the second slider 805 more stable. The two ends of the screw 803 are rotatably connected to the inner walls of both sides of the guide groove 801. The motor 804 is located outside the worktable 1, and its drive end is connected to the screw 803. The second slider 805 is located inside the guide groove 801 and is threadedly connected to the screw 803. The dovetail slider 806 is located at the top of the second slider 805. The dovetail-shaped slide block 806 is slidably connected to the dovetail-shaped slide groove 802. The dovetail structure makes the movement of the clamping block 7 on the worktable 1 more stable and prevents the slider and slide groove from separating due to thermal expansion and contraction. The connecting block 807 is set at the top of the dovetail-shaped slider 806, and one side of the connecting block 807 is connected to the clamping block 7. The inner walls of the guide groove 801 at both ends are provided with guide rails 9. The second slider 805 has second slide grooves 10 at both ends that match the guide rails 9. The motors 804 on both sides drive the screw 803 to rotate, driving the second slider 805 to move horizontally along the guide rails 9, guide grooves 801, and screw 803. At the same time, the dovetail-shaped slider 806 moves along the dovetail-shaped slide groove 802, driving the clamping block 7 to approach the side wall of the transformer body 2 and apply clamping force. In cooperation with the positioning column 5 and the limit block 503, the transformer body is firmly and stably fixed on the worktable, and it is not easy to deviate due to external force, making the processing and inspection more accurate.
[0021] The upper surface of the support platform 4 is evenly provided with multiple second mounting holes 401. The bottom end of the outer surface of the positioning post 5 is provided with external thread, and the inner wall of the second mounting hole 401 is provided with internal thread. The positioning post 5 is threadedly connected to the support platform 4 and can be installed in multiple positions, which is convenient for adjustment according to different types of transformers and has better practicality.
[0022] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
