[0035] Embodiment 2

[0036] On the basis of embodiment 1, the preferred embodiment of the metal clamping jaw convenient to adjust provided by the utility model comprises Figures 1 to 5 As shown in the figure: the mounting assembly 5 comprises: a clamping groove 507 opened in the lower end of one side of the clamping seat 3; a fixed groove 505 opened in the lower end of the front side of the clamping seat 3; a sliding rod 503 fixedly connected to the inner wall of the fixed groove 505, the surface of the sliding rod 503 being slidably connected with a sliding block 509, the surface of the sliding rod 503 being wound with a return spring 504, the two ends of the return spring 504 being fixedly connected with the inner wall of the sliding rod 503 and one side of the sliding block 509 respectively; a limiting plate 501 fixedly connected to the front of the sliding block 509; and a clamping block 508 fixedly connected to one side of the clamping block 4.

[0037] In the embodiment, the sliding clamping of the clamping block 508 and the inside of the clamping groove 507 is utilized, and then the elastic force of the return spring 504 is utilized to make the limiting plate 501 slide to limit or separate the front of the clamping groove 507, thereby realizing the quick disassembly and assembly of the clamping block 4 and the clamping seat 3, and avoiding the cumbersome inconvenience caused by the use of tools for disassembly and assembly every time in the traditional way of bolt fixing.

[0038] In the further preferred embodiment of the utility model, the front of the clamping seat 3 is tightly attached with the limiting plate 501, and one side of the front of the limiting plate 501 is fixedly connected with a pulling block.

[0039] In the embodiment, the tight attachment of the limiting plate 501 and the front of the clamping seat 3 realizes the limiting and fixing of the clamping block 508 and the inside of the clamping groove 507.

[0040] In the further preferred embodiment of the utility model, the front of the clamping seat 3 of the two ends of the fixed groove 505 is provided with a sliding groove 502, and the back of the limiting plate 501 is fixedly connected with a sliding block 506 which is in sliding cooperation with the inside of the sliding groove 502.

[0041] In the embodiment, the sliding of the sliding block 506 in the sliding groove 502 improves the smoothness of the sliding of the limiting plate 501.

[0042] In the further preferred embodiment of the utility model, the inside of the clamping block 508 and the clamping groove 507 constitute a clamping structure, and the shapes of the clamping groove 507 and the clamping block 508 are convex.

[0043] In this embodiment, the sliding between the convex locking block 508 and the slot 507 is used to improve the firmness and stability of the initial sliding installation between the clamping block 4 and the clamping seat 3.

[0044] In a further preferred embodiment of the present invention, a rubber pad 6 is fixedly connected to the inner wall of the clamping block 4, and the rubber pad 6 is in the shape of an isosceles trapezoid.

[0045] In this embodiment, an isosceles trapezoidal rubber pad 6 is used to achieve flexible contact between the clamping block 4 and the workpiece, avoiding wear on the workpiece surface caused by rigid clamping.

[0046] The working principle of this utility model is as follows: First, connect the connecting seat 8 to the output end of the external robot. Then, the drive source 7 can be used to make the fixed seat 1 slide, which in turn drives the clamping seat 3 to slide. Then, the workpiece can be clamped and fixed by the clamping block 4. When the length of the workpiece is longer than the maximum stroke of the drive source 7, the pull plate 204 can be pulled to drive the two adjusting rods 203 to slide upward, so that the positioning rod 206 rises and compresses the adjusting spring 208 until it is completely disengaged from the positioning hole 201. Then, the clamping seat 3 is pulled to drive the adjusting column 202 to slide into the adjusting groove 205 to a suitable position. Then, the pull plate 204 is released, and the elastic force of the adjusting spring 208 is used to make the positioning rod 206 slide down and lock into the appropriate positioning hole 201, so as to achieve the limit fixation after the adjusting column 202 slides. In this way, the distance between the fixed seat 1 and the clamping seat 3 can be changed, so that longer workpieces can be clamped and fixed, avoiding the limitations caused by the fixed stroke of the drive source 7.

[0047] Meanwhile, when different workpiece shapes require different clamping blocks 4, the limiting plate 501 can be moved to drive the sliding block 509 to slide, so that it slides on the surface of the slide rod 503 to compress the return spring 504 until it is completely separated from the slot 507. Then, the clamping block 4 can be moved forcefully to make the clamping block 508 completely slide away from the inside of the slot 507, thus realizing the disassembly of the clamping block 4. During installation, the limiting plate 501 is moved first, and then the clamping block 508 is slid into the slot 507. After that, the limiting plate 501 is released, and the elastic force of the return spring 504 is used to make the sliding block 509 slide to drive the limiting plate 501 to slide back to its original position, thereby limiting and fixing the front of the clamping block 508. This realizes the quick disassembly and assembly between the clamping block 4 and the clamping seat 3, avoiding the cumbersome inconvenience caused by the traditional bolt fixing, which requires the use of tools for each disassembly and assembly.

[0048] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
