Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a clamp for producing aluminum film speakers. Background Art

[0002] During the processing of the speaker, it is necessary to connect cables to the two connection contacts of the speaker, so that the speaker can be electrically connected to an external controller through the cables when in use. When welding the connection contacts and cables on the speaker, some manual welding methods require the operator to remove the speaker from the conveyor belt and hold the welding gun and the cable to solder the cable to the connection contacts;

[0003] When welding the connecting contacts and cables of the above-mentioned speakers, due to the particularity of the speaker structure, the ends of the speakers need to be fixed to facilitate welding of the connecting contacts of the speakers. However, in the existing speaker welding process, manual or pneumatic clamping tools are mostly used to clamp and fix the speakers. During use, the manual clamping tools still require the operator to repeatedly open and close the tools, which reduces the welding efficiency of the speaker connecting contacts. In addition, most pneumatic clamps simply use cylinders and clamping parts to clamp the speakers. However, although the rigid clamping parts and cylinders can achieve rapid clamping of the speakers, it is difficult to adjust and control the displacement process of the piston end of the cylinder. When clamping and fixing speakers with different end diameters, it is easy to make the clamping force too large, resulting in deformation or even damage to the speaker end shell. When the displacement process of the cylinder piston end is insufficient, it will affect the stable clamping of the speaker by the clamping part, thereby affecting the welding of the speaker connecting contacts.

[0023] like Figure 1-Figure 4 As shown, the utility model provides a clamp for producing aluminum diaphragm speakers, including two bottom plates 1, an inclined plate 2 and a top plate 3. Two support plates 4 are fixedly installed at the lower end of the inclined plate 2, and the lower end of the support plate 4 is fixedly installed on the corresponding bottom plate 1. A cylinder 5 is also fixedly installed at the lower end of the inclined plate 2 between the two bottom plates 1. The cylinder 5 is connected to an external air pump through an air pipe. A connecting plate 12 is fixedly installed at the output end of the cylinder 5.

[0024] like Figure 2 As shown, first guide grooves 10 are opened on both sides of the bottom plate 1, and first guide grooves 10 are opened on both sides of the inclined plate 2. The lower end of the bottom plate 1 is fixedly installed on the operating table, and the lower end of the cylinder 5 passes through the through groove in the operating table and extends to the position below the operating table. The obliquely arranged inclined plate 2 can realize oblique clamping of the speaker, thereby facilitating welding of the electrical connection contacts and cables on the speaker. Guide plates 11 are fixedly installed on both sides of the top plate 3, and the lower ends of the guide plates 11 pass through the first guide grooves 10 on one side of the bottom plate 1 and the inclined plate 2 in turn and are fixedly connected to one side of the connecting plate 12.

[0025] like Figure 2-Figure 4 As shown, a second guide groove 13 is provided in the side plate 6, and a countersunk hole 14 is also provided on one side of the upper end of the side plate 6, and the countersunk hole 14 is connected to the second guide groove 13 channel, and a connecting screw 15 is inserted and installed in the countersunk hole 14, and one end of the connecting screw 15 is threadedly connected to the screw groove inside the second guide groove 13. With the arrangement of the side plate 6 and the second guide groove 13, the guided movement of the slider 7 can be achieved, and an oblique sliding hole 17 is provided in the slider 7.
