The return mechanism 44 includes a post 441 and a return spring 442. The upright post 441 is fixed on the bottom plate 5 and perpendicular to the bottom plate 5. The return spring 442 is fitted over the post 441. The cable fixing table 43 presses the return spring 442 during the downward movement.
The working process of the clamp in the embodiment of the invention will be briefly described as follows:
referring to fig. 13, a top view of a fixture in an embodiment of the invention is shown. The first material clamping part 1 and the second material clamping part 2 are arranged transversely, and the third material clamping part 3 is arranged vertically. The first clamping portion 1, the second clamping portion 2 and the third clamping portion 3 cooperate with each other to combine the first workpiece, the second workpiece and the third workpiece, including but not limited to the following steps:
the first clamping part 1 pushes the first workpiece to a preset position;
the second clamping part 2 pushes the second workpiece to a preset position;
the third clamping part 3 pushes the third workpiece to a preset position.
The three steps can be performed in the required sequence in specific application. The execution order is set in order to combine the first, second and third workpieces in a rational manner such that the first, second and third workpieces constitute a physical structure or conceptual whole.
Taking an earphone cable as an example, the earphone cable comprises three workpieces, namely a metal shell A, a metal shell B and a plug C with a circuit. Assume that metal shell a is the first workpiece in an embodiment of the present invention, metal shell B is the second workpiece in an embodiment of the present invention, and plug C is the third workpiece in an embodiment of the present invention. In the combination process of the metal shell A, the metal shell B and the plug C, the metal shell A partially wraps the metal shell B, and the metal shell A and the metal shell B jointly wrap the plug C.
Referring to fig. 10 and 11, after the third positioning tongue 3244 positions the plug C, the third pushing cylinder 31 pushes the plug C to a preset position. The upper jaw 3242 is reset by the upper jaw spring 3242a, clamping the plug C together with the lower jaw 3243.
Referring to fig. 4, 7 and 13, the first clamping part 1 and the second clamping part 2 are moved to respective preset positions in opposite directions such that the metal case a is wrapped around both upper and lower surfaces of the metal case B. In the process that the metal shell a wraps the metal shell B, the first upper pressing head 1221 and the first lower pressing head 1222 press the upper small pressing head 2221B and the lower small pressing head 2222B, so that the upper small pressing head 2221B and the lower small pressing head 2222B retract (when the second positioning tongue 2224, the upper small pressing head 2221B and the lower small pressing head 2222B position the metal shell B, the upper small pressing head 2221B enters the upper side of the metal shell B, and the lower small pressing head 2222B enters the lower side of the metal shell B), so that the metal shell a wraps the upper surface and the lower surface of the metal shell B. During the process of moving the first material clamping part 1 and the second material clamping part 2 towards each other, the second positioning sheet 2223 vertically defines the position of the plug C. When the position of the plug C is in accordance with the preset, the metal shell A and the metal shell B jointly wrap the plug C.
Referring to fig. 12 and 13, after the metal shell a, the metal shell B and the plug C are combined, the cable is fixed on the cable fixing table 43 of the cable fixture 4, so as to define the relative position of the plug C and the cable. In the embodiment of the present invention, the metal shell a, the metal shell B, the plug C, and the cable wires are finally welded together.
In the clamp in the above embodiment, the first workpiece is clamped and positioned by the first clamping portion 1, the second workpiece is clamped and positioned by the second clamping portion 2, and the third workpiece is clamped and positioned by the third clamping portion 3, so that the first workpiece, the second workpiece, and the third workpiece enter and are fixed at the preset positions. The first clamping part 1, the second clamping part 2 and the third clamping part 3 are matched with each other to combine the first workpiece, the second workpiece and the third workpiece, so that preparation is made for subsequent welding, assembling and other processes. In addition, the working processes of the first material clamping part 1, the second material clamping part 2 and the third material clamping part 3 can realize automatic operation, and the various steps can be completed quickly and accurately. In conclusion, the clamp overcomes the problems of insufficient positioning precision and low combination efficiency in the prior art, and is beneficial to improving the production efficiency and the product quality of a data line/charging line/earphone line connector of an electronic product.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the same. Although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention. And such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
