Description

Technical Field

[0001] This utility model relates to a welding fixture for spring contact fingers, belonging to the field of spring contact finger technology. Background Technology

[0002] Spring contacts, also known as annular inclined springs, can transmit high currents in small spaces and can also be used for purely mechanical connections. Spring contacts are characterized by their simple structure, small size, high conductivity, and cost-effectiveness, and are widely used in the aerospace and electronics industries.

[0003] Chinese Patent Publication No. (CN 217618580 U) discloses a welding fixture for spring contact fingers, including a worktable. A connecting plate is fixedly connected to one side of the outer surface of the worktable, and a lower cover plate is provided on the other side of the outer surface of the worktable. An upper cover plate is provided on the upper surface of the lower cover plate. If the two ends of the spring are not aligned, the user can rotate the handle. The handle drives the threaded block to move through the threaded rod. The threaded block drives the adjusting gear to rotate around the fixed shaft through the external teeth. The angle of the adjusting pin can be changed, which makes it easier to align the two ends of the spring and improves the accuracy of welding. This solves the problem that the current welding of spring contact fingers lacks corresponding tooling equipment and still uses manual welding. The operator bends the spring contact finger into a circle shape and then welds the two ends to fix it. In this process, the welding efficiency is not only low, but the welding process is also prone to accidental injury to personnel, which is not safe. Moreover, when the two ends of the spring are flipped, the two ends are prone to misalignment, which affects the welding quality.

[0004] The aforementioned device mainly relies on adjusting the angle of the locking pins to align the two ends of the spring. However, in actual use, because the spring itself has tension, if it cannot be fixed when bent, the spring may bounce off due to its own tension, thus affecting the subsequent normal welding work at both ends and making it inconvenient for operators to use.

[0005] To address this, a welding fixture for spring contact fingers is proposed. Utility Model Content

[0006] In view of this, the present invention provides a spring contact finger welding fixture to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0007] The technical solution of this utility model is implemented as follows: a spring contact finger welding fixture, comprising: A winding assembly, comprising a worktable, a processing box fixedly mounted on the top of the worktable, and a circular box fixedly mounted on the bottom of the inner cavity of the processing box; A clamping assembly includes a housing and a motor. The housing is fixedly installed at the bottom of the worktable, and the motor is located at the bottom of the housing. A turntable is movably connected to the bottom of the inner cavity of the housing. The surface of the turntable is provided with arc-shaped grooves. Mounting rods are movably connected to the inner cavities of the three arc-shaped grooves. Movable blocks are fixedly installed on the tops of the three mounting rods. Vertical rods are fixedly installed on the tops of the three movable blocks. First clamping plates are fixedly installed on the tops of the three vertical rods.

[0021] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0022] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] Example 1 like Figure 1-5 As shown, this utility model embodiment provides a spring contact finger welding fixture, including: The winding assembly 1 includes a worktable 101, a processing box 102 is fixedly installed on the top of the worktable 101, and a circular box 103 is fixedly installed at the bottom of the inner cavity of the processing box 102. The clamping assembly 2 includes a housing 201 and a motor 202. The housing 201 is fixedly installed at the bottom of the workbench 101. The motor 202 is located at the bottom of the housing 201. A turntable 203 is movably connected to the bottom of the inner cavity of the housing 201. The surface of the turntable 203 is provided with arc-shaped grooves 204. Mounting rods 205 are movably connected to the inner cavities of the three arc-shaped grooves 204. Moving blocks 206 are fixedly installed on the top of the three mounting rods 205. Vertical rods 207 are fixedly installed on the top of the three moving blocks 206. First clamping plates 208 are fixedly installed on the top of the three vertical rods 207. A screw 209 is threadedly connected to the surface of the processing box 102. A knob 210 is fixedly installed on the front side of the screw 209. A second clamping plate 211 is movably connected to the rear side of the screw 209. The motor 202 is fixedly installed at the bottom of the housing 201. The output end of the motor 202 is fixedly connected to the bottom of the turntable 203.

[0024] By setting up the clamping assembly 2, the output of the motor 202 can cause the moving block 206 to drive the first clamping plate 208 to move inward, so that the spring is wrapped around the outside of the circular box 103. Then, the screw 209 drives the second clamping plate 211 to move inward, clamping both ends of the spring, so that the spring is in a circular state, which is convenient for welding. At the same time, due to the limitation of the first clamping plate 208, the spring will not bounce off due to its own tension, ensuring the stability of subsequent welding.

[0025] Example 2 like Figure 1-6 As shown, in one embodiment, limit rods 212 are fixedly installed on both the left and right sides of the front side of the second clamping plate 211. The limit rods 212 penetrate the inner surface of the processing box 102 and extend to the front side of the processing box 102. The bottom of the inner cavity of the processing box 102 is provided with a moving groove 213. The three vertical rods 207 penetrate the inner cavity of the three moving grooves 213 and extend into the inner cavity of the processing box 102. Guide rods 214 are fixedly installed around the inner cavity of the box body 201. The three moving blocks 2 06 are slidably connected to the surfaces of the three guide rods 214. The bottom of the inner cavity of the box 201 is provided with a limiting groove 215. The three mounting rods 205 pass through the inner cavity of the three limiting grooves 215 and extend to the bottom of the box 201. The surfaces of the three first clamping plates 208 are fixedly installed with protective pads 216. The protective pads 216 are made of rubber. The bottom of the workbench 101 is fixedly installed with a base plate 104. The top of the base plate 104 is threaded with anchor bolts 105 around its perimeter.

[0026] By setting the limiting rod 212, the movement of the second clamping plate 211 can be limited, preventing the second clamping plate 211 from rotating synchronously with the screw 209. By setting the moving groove 213, the movement of the vertical rod 207 can be limited, preventing the vertical rod 207 from deviating during movement, thus affecting the fixing of the spring. By setting the guide rod 214, the movement of the moving block 206 can be limited, preventing it from deviating during movement, thus affecting the clamping of the spring. By setting the limiting groove 215, the movement of the mounting rod 205 can be limited, preventing the mounting rod 205 from changing direction during movement, thus affecting the limiting of the spring. By setting the protective pad 216, the clamped spring can be protected, preventing scratches on the spring surface during clamping. By setting the anchor bolt 105, the overall equipment can be stabilized, preventing the equipment from shaking due to accidental collisions.

[0027] When this utility model is in operation: the spring is placed inside the first clamping plate 208. At this time, through the output of the motor 202, the motor 202 drives the turntable 203 to rotate. At this time, due to the cooperation of the arc groove 204 and the limiting groove 215, the mounting rod 205 drives the moving block 206 to move inward. At this time, the moving block 206 simultaneously drives the vertical rod 207 and the first clamping plate 208 to move inward. The first clamping plate 208 clamps the spring. At this time, the two ends of the spring are located behind the second clamping plate 211. Then, by rotating the knob 210, the second clamping plate 211 rotates synchronously. At this time, the screw 209 drives the second clamping plate 211 to move backward. The second clamping plate 211 clamps and fixes the two ends of the spring, thereby completing the winding work of the spring, which facilitates the operator to weld the two ends of the spring later.

[0028] The above description is only a specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art can easily conceive of various changes or substitutions within the technical scope disclosed in the present utility model, and these should all be included within the protection scope of the present utility model.
