After the servo motor 3 is started, the gear 5 will be driven to rotate. When the gear 5 rotates counterclockwise, it drives the two meshed racks 9 to move left and right respectively. The two racks 9 move relative to each other, driving the auxiliary block 7 to move at one end of the reinforcement rod 6.

[0024] Embodiment 2:

[0025] Based on the first embodiment, Figure 1 and Figure 4As shown, a plurality of circular holes 16 are provided on both sides of the clamping table 2, and a support bar 15 is provided on one side of the two side panels 14. One end of the two support bars 15 is rotatably connected to the internal threads of the plurality of circular holes 16 respectively. The utility model is a clamping and positioning device for mechanical processing. By providing the side panels 14, the support bars 15, the circular holes 16 and the extension plate 10, after the rack 9 applies pressure to the L-shaped block 8, it will drive the auxiliary block 7 to move at one end of the reinforcement rod 6, and the side panel 14 can move on the top of the clamping table 2.

[0026] Working principle: Mechanical processing can be divided into cutting processing and pressure processing according to the processing method. The clamp is used to fix the processing object in the mechanical manufacturing process so that it occupies the correct position, so that the operator can perform corresponding processing operations on the workpiece. The clamping and positioning device refers to the clamp, which can clamp the workpiece. The clamping table 2 can clamp two workpieces at the same time, which speeds up the processing of the workpieces and increases the use range of the positioning device. The workpieces are placed on both sides of the top of the clamping table 2 in turn, and are respectively located between the clamping plate 13 and the side plate 14. After starting the servo motor 3, it will drive the gear 5 to rotate. When the gear 5 rotates counterclockwise, it drives the two meshing racks 9 to move left and right respectively. The two racks 9 move relative to each other, driving the auxiliary block 7 to move at one end of the reinforcement rod 6, and the clamping plates 13 are respectively aligned with the side plates 14 are close to each other, so that the two workpieces can be clamped by the clamping plate 13 and the side plate 14, which improves the efficiency of the positioning device. When the gear 5 rotates clockwise, it drives the two racks 9 to move toward each other and the two are away from each other. Therefore, the workpiece can be clamped according to the length of the workpiece by utilizing the movement of the clamping plate 13. After the rack 9 applies pressure to the L-shaped block 8, it will drive the auxiliary block 7 to move at one end of the reinforcement rod 6. The side plate 14 can move on the top of the clamping platform 2. After the support bar 15 is embedded into the side plate 14 and the circular hole 16, the three are threadedly connected, so that the side plate 14 can be firmly installed on the top of the clamping platform 2. Therefore, the distance between the side plate 14 and the clamping plate 13 can be adjusted again. The vertical plate 11 and the clamping plate 13 are connected by two extension rods 12, and the two are relatively stable.
