[0020] A supporting plate 10 is arranged at the edge of the front end surface of the bracket mounting plate 6, one side of the supporting plate 10 is a limit baffle, a slide groove 11 is arranged on the outer surface of the bracket mounting plate 6 facing the supporting plate 10, a second driving motor 12 is fixedly installed on the outer side of the bracket mounting plate 6, a second screw rod 13 is rotatably connected to the end of the second driving motor 12, and the second screw rod 13 is located inside the bracket mounting plate 6, a second nut seat 14 is slidably installed on the second screw rod 13, a slider 15 is connected to the outer side of the second nut seat 14, a clamping plate 16 is connected to the outer side of the slider 15, and the clamping plate 16 is located on the surface of the supporting plate 10;

[0021] An electric telescopic rod 17 is fixedly mounted on the outer surface of the base 7 , and the end of the telescopic shaft at the bottom of the electric telescopic rod 17 passes through the bracket mounting plate 6 and is connected to a bottom plate 18 , and the bottom plate 18 is located directly below the bottom of the supporting plate 10 .

[0022] The first nut seat 5 and the second nut seat 14 are both equipped with circulating balls for driving with the screw rod. The first drive motor 4 and the second drive motor 12 are both forward and reverse motors, which are used to control the forward and reverse rotational motion of the first screw rod 3 and the second screw rod 13 respectively.

[0023] When the first drive motor 4 drives the first screw rod 3 to rotate, the bracket mounting plate 6 moves transversely on the first screw rod 3 through the first nut seat 5;

[0024] When the second drive motor 12 drives the second screw rod 13 to rotate, the clamping plate 16 and the slider 15 move transversely on the second screw rod 13 through the second nut seat 14 .

[0025] The electric telescopic rod 17 drives the bottom plate 18 to move up and down through the bottom telescopic shaft, so as to adjust the height distance between the bottom plate 18 and the supporting plate 10, thereby adapting to the clamping and supporting effect of the end edges of workpieces with different thicknesses.

[0026] Working principle:

[0027] In this solution, the structure on the entire bracket mounting plate 6 is used to support the workpiece during machining. According to actual work needs, the support frame 1 and the first screw rod 3 can be installed on the left and right sides of the construction platform respectively. In this case, the left and right ends of the workpiece are supported by two symmetrical bracket mounting plates 6 respectively; it is also possible to only use Figure 1 The two support frames 1 and a separate structure of a first screw rod 3 support the workpiece. It can be selected whether to install symmetrically on the left and right sides of the construction platform or only on one side of the construction platform according to the size of the workpiece;

[0028] The bracket mounting plate 6 as a whole performs a horizontal lateral movement on the first screw rod 3 through the first nut seat 5. When the first drive motor 4 drives the first screw rod 3 to rotate forward, the bracket mounting plate 6 moves to the right on the first screw rod 3 through the first nut seat 5. When the first drive motor 4 drives the first screw rod 3 to rotate reversely, the first nut seat 5 drives the bracket mounting plate 6 to perform a leftward reset lateral movement, thereby realizing the displacement movement of the bracket mounting plate 6, which is convenient for the workpiece to be adjusted to the left and right lateral movement after being fixed on the bracket mounting plate 6.

[0029] When the workpiece needs to be clamped, the workpiece can be placed on the support plate 10 or between the support plate 10 and the bottom plate 18 for clamping and supporting. The two clamping and supporting methods are as follows:

[0030] 1. When the workpiece is placed on the supporting plate 10 and supported, the second driving motor 12 can be operated to drive the second screw rod 13 to rotate inside the bracket mounting plate 6. Therefore, under the working principle of the ball screw, the second nut seat 14 can move laterally on the second screw rod 13 through the internal circulating ball. During the displacement of the second nut seat 14, the slider 15 is driven to slide on the slide groove 11. The clamping plate 16 outside the slider 15 can slide toward the side baffle of the supporting plate 10, so that the workpiece is clamped and supported by the clamping plate 16 and the supporting plate 10. At the same time, the pull rod 8 is manually pushed forward to move the L-shaped limit plate 9, and the top of the workpiece can be limited by the L-shaped limit plate 9 (suitable for supporting workpieces with smaller volumes. In this case, the workpiece is supported by a bracket mounting plate 6 on one side of the construction platform);

[0031] Second, when the workpiece is placed between the supporting plate 10 and the bottom plate 18, the electric telescopic rod 17 on the outer surface of the base 7 can be operated to control the bottom plate 18 to move upward, so as to clamp the end edge of the workpiece in the up and down directions. It is used for clamping the left and right ends of the workpiece and can adapt to the clamping and supporting of workpieces of different thicknesses (in this case, the present structure is installed on both sides of the construction platform, that is, two symmetrical bracket mounting plates 6 on the left and right, which are respectively used to clamp the left and right ends of the supporting workpiece).

[0032] In summary, different clamping and supporting methods of the workpiece can be selected according to the needs of different workpiece sizes, thereby improving the convenience of the workers in the process of processing the workpiece.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
