Abstract
Description
Technical Field
[0001] This utility model relates to the field of loudspeaker processing technology, and in particular to a loudspeaker processing welding fixture. Background Technology
[0002] A loudspeaker is a transducer that converts electrical signals into sound signals. Audio electrical energy vibrates its cone or diaphragm through electromagnetic, piezoelectric, or electrostatic effects, causing it to resonate with the surrounding air and produce sound. Its structure includes a frame, surround, cone, centering support, magnetic plate, voice coil, magnet, and magnetic post, and it is commonly found in sound-producing electronic and electrical equipment.
[0003] Currently, loudspeakers require welding and assembly during production. For example, the cone, centering support, magnetic plate, magnet, and other structures are all welded into the frame. During the welding process, the frame is usually fixed using positioning equipment, and workers adapt to the frame position by changing their own position to complete the welding of each structure. However, when welding structures in different positions, workers need to frequently move their own positions, which reduces welding efficiency. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a speaker processing and welding fixture.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A speaker welding fixture includes a processing table. A groove is formed on the upper surface of the processing table. Two sliders are slidably connected to the inner wall of the groove. Positioning components are fixedly connected to the upper surfaces of the two sliders. Each positioning component includes a strip plate, and a support frame is fixedly connected to the upper surface of the strip plate. A first arc-shaped frame and a second arc-shaped frame are fixedly connected to the upper surfaces of the two support frames, respectively. Arc-shaped grooves are formed on the inner walls of both the first and second arc-shaped frames. Limiting grooves are formed on the bottom and top walls of the arc-shaped grooves. Arc-shaped blocks are slidably connected to the inner walls of the arc-shaped grooves. Limiting rods are fixedly connected to the upper and lower surfaces of the arc-shaped blocks. A locking frame is fixedly connected to the end of the arc-shaped block away from the inner wall of the arc-shaped groove. A positive and negative threaded rod is rotatably connected to the left inner wall of the groove. The right end of the positive and negative threaded rod extends to the right side of the processing table and is fixedly connected to a handwheel.
[0007] Preferably, both sliders have threaded holes on their sides, and the two sliders are threaded to the positive and negative threads on the surface of the positive and negative threaded rods through the threaded holes.
[0008] Preferably, the lower surfaces of both strip plates are slidably connected to the upper surface of the processing table, and the two strip plates and the support frame are at the same height.
[0009] Preferably, the first arc frame and the second arc frame are the same size, and the positions of the two sets of arc grooves and the limiting grooves are the same, and the two limiting rods are slidably connected to the inner walls of the two limiting grooves respectively.
[0010] Preferably, the locking assembly includes a circular frame, a locking groove is provided on the side of the circular frame, a locking plate is slidably connected to the inner wall of the locking groove, a bearing seat is fixedly connected to the upper surface of the locking plate, and the two circular frames are at the same height.
[0011] Preferably, the upper surface of the circular frame is provided with a screw hole, and a threaded rod is threadedly connected to the inner wall of the screw hole. The bottom end of the threaded rod is fixedly connected to the inner wall of the bearing seat.
[0012] The beneficial effects of this utility model are as follows:
[0013] By combining the positioning and locking components, the speaker frame can be clamped by the locking components during use, thanks to the separate structure of the first and second arc-shaped frames. After the first and second arc-shaped frames are combined, the arc-shaped block and the limiting rod can slide freely within the first and second arc-shaped frames. This allows the speaker frame to be clamped while rotating freely, eliminating the need for workers to change their welding position to adapt to the speaker frame. Instead, the frame can be rotated to adapt to the welding gun position, thus improving welding efficiency. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Example:
[0021] Reference Figure 1-4 A speaker processing and welding fixture includes a processing table 1. A groove is formed on the upper surface of the processing table 1. Two sliders 2 are slidably connected to the inner wall of the groove. A positioning component is fixedly connected to the upper surface of each slider 2. The positioning component includes a strip plate 3. A support frame 4 is fixedly connected to the upper surface of the strip plate 3. A first arc frame 5 and a second arc frame 6 are fixedly connected to the upper surface of the two support frames 4 respectively. Arc grooves are formed on the inner walls of the first arc frame 5 and the second arc frame 6. Limit grooves are formed on the inner bottom wall and the inner top wall of the arc groove. Arc blocks 7 are slidably connected to the inner wall of the arc groove. Limit rods 8 are fixedly connected to the upper and lower surfaces of the arc blocks 7. A locking component 9 is fixedly connected to the end of the arc blocks 7 away from the inner wall of the arc groove. A positive and negative threaded rod 10 is rotatably connected to the left inner wall of the groove. The right end of the positive and negative threaded rod 10 extends to the right side of the processing table 1 and is fixedly connected to a handwheel 11.
[0022] Both sliders 2 have threaded holes on their sides. The two sliders 2 are threaded to the positive and negative threads on the surface of the positive and negative threaded rod 10 through the threaded holes. The lower surfaces of the two strip plates 3 are slidably connected to the upper surface of the processing table 1. The two strip plates 3 and the support frame 4 have the same height. The first arc frame 5 and the second arc frame 6 have the same size. The two sets of arc grooves and the limiting grooves are in the same position. The two limiting rods 8 are slidably connected to the inner walls of the two limiting grooves.
[0023] First, the surface of the speaker frame is fixed using the locking assembly 9. Then, the handwheel 11 is turned, which drives the positive and negative threaded rods 10 to rotate. The positive and negative threaded rods 10 can drive the two sliders 2 to move closer to each other through their own positive and negative threads. The two sliders 2 can drive the first arc frame 5 and the second arc frame 6 to move closer to each other through the two sets of strip plates 3 and the support frame 4, until the first arc frame 5 and the second arc frame 6 form a complete ring. At this time, the arc block 7 and the limiting rod 8 can slide freely on the inner walls of the first arc frame 5 and the second arc frame 6, so that the speaker frame held by the two sets of locking assemblies 9 can rotate freely, thereby improving the welding efficiency of the speaker frame.
[0024] The locking assembly 9 includes a circular frame 12, with a locking groove on the side of the circular frame 12. A locking plate 13 is slidably connected to the inner wall of the locking groove. A bearing seat 14 is fixedly connected to the upper surface of the locking plate 13. The two circular frames 12 are at the same height. A screw hole is provided on the upper surface of the circular frame 12. A threaded rod 15 is threadedly connected to the inner wall of the screw hole. The bottom end of the threaded rod 15 is fixedly connected to the inner wall of the bearing seat 14. The two circular frames 12 can cooperate with each other to clamp the basin frame. After rotating the threaded rod 15, the locking plate 13 can be moved up and down in the locking groove through the bearing seat 14. The locking plate 13 can cooperate with the inner bottom wall of the locking groove to clamp and lock the basin frame. It can be used for basin frames of different thicknesses and can ensure the stability of the basin frame during the welding process, with high flexibility.
[0025] Working principle: First, insert the speaker frame into the locking groove on the side of the circular frame 12. Then, rotate the threaded rod 15 to lower the locking plate 13, thereby clamping the frame. Rotate the handwheel 11, which drives the two sliders 2 to move closer together through the positive and negative threaded rods 10. At this time, the two sliders 2 can drive the first arc frame 5 and the second arc frame 6 to move closer together through the two strip plates 3 and the support frame 4, until the first arc frame 5 and the second arc frame 6 form a complete ring. During the process of the first arc frame 5 and the second arc frame 6 moving closer together, the frame can be inserted into the locking groove on the side of another circular frame 12 and held in place by the locking plate 13. The frame can be locked by the two sets of circular frames 12. At the same time, rotating the frame can drive the two arc blocks 7 to rotate in the arc groove through the two circular frames 12, which can easily and flexibly change the position of the frame. Therefore, the operator does not need to move the frame to perform welding operations, which greatly reduces the welding difficulty and improves the welding efficiency.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
