Description

Technical Field

[0001] This utility model relates to a transformer winding conductor welding and fixing device, belonging to the field of transformer auxiliary tooling technology. Background Technology

[0002] Currently, epoxy resin dry-type transformers are widely used due to their excellent properties. Improving product performance and reducing costs have always been key concerns for transformer manufacturers. The technical and economic indicators of dry-type transformers determine the future prospects of transformer manufacturers. The welding of winding conductors in dry-type transformers uses butt welding. Previously, this method required two people: one person held the conductor for fixing and the butt joint, while the other welded. Hand-held fixing inevitably resulted in shaking or misalignment of the two conductors, leading to weld fluid flow, misalignment, and defects such as burrs and bumps, causing inter-turn short circuits or increased partial discharge. Therefore, this design proposes a transformer winding conductor welding and fixing device to avoid these previous technical problems. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, this utility model provides a technology for welding and fixing transformer winding wires.

[0004] This utility model is achieved through the following technical solution:

[0005] A transformer winding conductor welding and fixing device, characterized in that it includes an operating table base and a welding and fixing assembly connected thereto.

[0006] The welding fixing assembly includes an upward bracket welded to the base of the operating table and a fixing platform extending forward at the front end of the operating table base. A lead screw with a rotating handle is installed in the light hole of the bracket. A telescopic rod outer wall is welded to the bottom of the bracket. A telescopic pressure rod is fitted inside the outer wall of the telescopic rod. A pressure plate is welded to the lower end of the telescopic pressure rod. The pressure plate corresponds to the fixing platform to clamp the workpiece to be welded. The telescopic pressure rod is connected to the lead screw.

[0007] Preferably, the telescopic pressure bar adopts a square structure to prevent it from rotating or moving left or right; the outer wall of the telescopic bar corresponds to the telescopic pressure bar, and the inner wall is also a square structure;

[0008] The lower end of the lead screw is screwed into the internal threaded hole of the telescopic pressure rod. The lead screw is positioned and installed in the light hole of the bracket in the vertical direction, so that the lead screw cannot be raised or lowered and the pressure plate cannot be rotated. The telescopic pressure rod can be moved up and down by rotating the handle to drive the lead screw to rotate.

[0009] In a further preferred embodiment, a nut is welded to the upper part of the optical hole on the lead screw and a cover is fitted on the lead screw above the nut (the center hole of the cover is the optical hole and has no threads). After the lead screw is inserted into the optical hole of the bracket, the cover is welded to the bracket, so that the lead screw can rotate but cannot be raised or lowered.

[0010] A further preferred embodiment is that the operating table base adopts a double-hole fixing structure, that is, it has two platform fixing holes, which can be directly fixed to the winding machine or auxiliary operating platform by bolts.

[0011] A further preferred embodiment has a silicone pad attached to the underside of the pressure plate, or a silicone pad attached to the top of the mounting platform.

[0012] There are two sets of welding fixing components, one on the left and one on the right, which are connected to the front of the operating table base respectively. The two sets of welding fixing components are spaced a certain distance apart to leave space for welding the two wires that need to be butt welded.

[0013] The beneficial effects of this utility model are as follows: Practical experience has proven that the use of transformer winding wire welding and fixing equipment can achieve welding and fixing of wires of various specifications, avoiding problems such as welding wobbling and misalignment caused by manual hand-holding of wires. It ensures that the wire joints are flush and stable. The operating platform base adopts a double-hole fixing structure, which can be directly fixed to the winding machine or auxiliary operating platform, avoiding welding fluid flow and misalignment caused by hand-holding vibration or non-parallelism of two wires, thus preventing defects such as burrs and protrusions. It reduces the probability of inter-turn short circuits in the winding and the partial discharge of the transformer, improving the overall performance of the transformer. It is applicable to the winding and welding fixing processing of all transformer winding wires. Attached Figure Description

Detailed Implementation

[0016] The attached figure shows one embodiment of this utility model.

[0017] A transformer winding conductor welding and fixing device includes an operating platform base 6 and a welding and fixing assembly connected thereto. The welding and fixing assembly includes an upward bracket 2 welded to the operating platform base, a fixing platform 14 extending forward at the front end of the operating platform base, a lead screw 1 with a rotating handle 7 installed in the light hole of the bracket, a telescopic rod outer wall 4 welded to the bottom of the bracket, a telescopic pressure rod 5 sleeved inside the telescopic rod outer wall, a pressure plate 10 welded to the lower end of the telescopic pressure rod, the pressure plate corresponding to the fixing platform above and below to clamp the workpiece to be welded; the telescopic pressure rod is connected to the lead screw.

[0018] The telescopic pressure bar 5 adopts a square structure to prevent it from rotating or moving left or right; the outer wall 4 of the telescopic bar corresponds to the telescopic pressure bar, and the inner wall is also a square structure;

[0019] The lower end of the lead screw is screwed into the internal threaded hole of the telescopic pressure rod. The lead screw is positioned and installed in the light hole of the bracket in the vertical direction, so that the lead screw cannot be raised or lowered and the pressure plate cannot be rotated. The telescopic pressure rod can be moved up and down by rotating the handle to drive the lead screw to rotate.

[0020] A nut 15 is welded to the upper part of the light hole on the lead screw and the cover 16 is placed on the lead screw above the nut (the center hole of the cover is a light hole without threads). After the lead screw is inserted into the light hole of the bracket, the cover is welded to the bracket, so that the lead screw can rotate but cannot be raised or lowered.

[0021] The operating table base 6 adopts a double-hole fixing structure, that is, it has two platform fixing holes 9, which can be directly fixed to the winding machine or auxiliary operating platform by bolts.

[0022] A silicone pad 8 is attached to the bottom of the pressure plate 10, or a silicone pad is attached to the top of the fixing platform 14.

[0023] There are two sets of welding fixing components, one on the left and one on the right, which are connected to the front of the operating table base respectively. The two sets of welding fixing components are spaced a certain distance apart to leave space for welding the two wires that need to be butt welded.

[0024] A reinforcing plate 3 is welded between the outer wall 4 of the telescopic rod and the bracket 2.

[0025] In use, the winding conductor 11 is placed between the fixing platform 14 and the pressure plate 10 of a set of welding fixing components. The worker operates the rotating handle 7 to rotate the lead screw 1, which in turn causes the telescopic pressure rod 5 and the pressure plate 10 to descend, pressing the winding conductor 11 firmly. The welding conductor 12 is then placed between the fixing platform 14 and the pressure plate 10 of another set of welding fixing components, so that the joints to be welded of the winding conductor 11 and the welding conductor 12 are joined together, forming the welding joint 13. The worker operates the rotating handle to press the welding conductor 12 firmly. The welding machine is then started to weld the welding joint 13 of the winding conductor 11 and the welding conductor 12 firmly and smoothly.

[0026] The workers operate two rotating handles 7 to drive the lead screw 1 to rotate in the opposite direction. The lead screw drives the telescopic pressure rod 5 and the pressure plate 10 to rise, releasing the winding conductor 11 and the welding conductor 12, and removing the welded winding conductor 11 and the welding conductor 12.
