When clamping a workpiece, place the workpiece between the two clamping plates 7, and open the cylinders 6 at both ends respectively, so that the clamping plates 7 move towards each other, which can conveniently clamp the workpiece. Since the side walls of the clamping plates 7 are both flat surfaces, the bottom and top surfaces of the clamped workpiece can be completely exposed, facilitating the comprehensive machining of the surface of the workpiece.

[0020] Embodiment 2

[0021] In order to facilitate the support of the workpiece to be machined, in this embodiment, as Figures 1-2As shown in the figure, a lifting platform 9 is arranged above the base 1. Inside both ends of the lifting platform 9, moving holes 18 are symmetrically arranged. The lifting platform 9 is respectively sleeved outside the outer side walls of the first support plate 2 and the second support plate 3 through the moving holes 18 at both ends. A plurality of top plates 14 are arranged at equal intervals on the upper end of the lifting platform 9. Screw rods 15 are rotatably connected to the bottom surfaces of the top plates 14. The lower ends of the screw rods 15 penetrate through the inside of the lifting platform 9 to the lower part of the lifting platform 9. Limiting columns 16 are symmetrically and fixedly installed on the bottom surfaces of the top plates 14. The lower ends of the limiting columns 16 all penetrate through the inside of the lifting platform 9 to the lower part of the lifting platform 9. Inside the top surface of the base 1, grooves 17 are arranged at equal intervals. The positions of the grooves 17 correspond to the positions of the top plates 14. The widths of the grooves 17 are all larger than the widths of the top plates 14. By respectively rotating the screw rods 15, the top plates 14 can be conveniently moved to make the top surfaces between the top plates 14 horizontal after moving. Then, the workpiece is placed on the top plates 14, and the top plates 14 support it.

[0022] Embodiment 3

[0023] In order to facilitate the up and down movement of the position of the lifting platform 9, in this embodiment, as Figures 1-2 shown, a first fixing plate 11 and a second fixing plate 12 are respectively fixedly installed on the right side wall of the first support plate 2 and the left side of the second support plate 3. A limiting rod 10 is fixedly installed between the first fixing plate 11 and the base 1. A lead screw 13 is rotatably connected between the second fixing plate 12 and the base 1. A second reciprocating motor 19 is fixedly installed at the upper end of the second fixing plate 12. The output shaft of the second reciprocating motor 19 is fixedly connected to the upper end of the lead screw 13 through the inside of the second fixing plate 12. The left end of the lifting platform 9 is threadedly sleeved on the rod wall of the lead screw 13, and the right end is slidably sleeved on the rod wall of the limiting rod 10. When supporting the workpiece, the second reciprocating motor 19 is turned on to make the lead screw 13 rotate, driving the lifting platform 9 to move up and down. When processing the workpiece, the lifting platform 9 is moved upward to support the workpiece. When turning the workpiece, the lifting platform 9 is moved downward to facilitate the turning work of the workpiece.

[0024] It should be noted that in this embodiment, when using the reversible mechanical processing tooling, as Figures 1-3As shown, place the workpiece on the top plate 14. Turn on the second reciprocating motor 19 to rotate the lead screw 13, driving the lifting table 9 to move up and down. Subsequently, according to the position where the workpiece needs to be clamped, rotate the screw 15 respectively, which can conveniently move the top plate 14, make the top surface between the moved top plates 14 horizontal, and make the top plate 14 support the workpiece. Then, turn on the air cylinders 6 at both ends respectively to make the clamping plates 7 move towards each other, which can conveniently clamp the workpiece. Since the side walls of the clamping plates 7 are all flat surfaces, the bottom and top surfaces of the clamped workpiece can be completely exposed, facilitating the comprehensive processing of the surface of the workpiece. When flipping the clamped workpiece, move the lifting table 9 downward, turn on the first reciprocating motor 8 to rotate the first rotating plate 4. Under the condition of the clamping force, it is convenient to rotate the second rotating plate 5, so that the workpiece can be conveniently flipped. After flipping, move the position of the lifting table 9 upward until the top plate 14 supports the workpiece.
