When the lead screw is started to rotate, two vice bodies are driven to move close to each other and clamp the workpiece on both sides. However, the existing bench vice still has certain disadvantages in use. Since the workpiece is not placed in the middle of the two vice bodies each time, when the two vice bodies move close to each other, one of the vice bodies inevitably collides with the workpiece first, resulting in different initial clamping forces on both sides (unnecessary damage to the local part of the workpiece).

The placing plate 6 comprises a plurality of clamping grooves 62 opened on the upper end of the supporting table 5, and the placing plate 6 further comprises a table plate 61, the bottom end of the table plate 61 is fixedly connected with a plurality of clamping blocks 63, the plurality of clamping blocks 63 are respectively inserted into the plurality of clamping grooves 62, and the width of the table plate 61 is greater than or equal to the width of the supporting table 5.

[0043] Specifically, the clamping jaw body 4 comprises a clamping plate 42 slidingly connected to the upper end of the guide stress plate 2, a containing cavity 44 is opened at the lower end of one side of each of the two clamping plates 42, a correction auxiliary part 7 is installed in each of the two containing cavities 44, the workpiece on the upper end of the placing plate 6 is corrected and centered through the two correction auxiliary parts 7, a direction changing positioning part 11 is installed at the upper end of one of the clamping plates 42, the direction changing positioning part 11 can be adjusted in horizontal position according to requirements, and the workpiece can be fixed vertically through the direction changing positioning part 11.

The upper ends of the two guiding force plates 2 are fixedly connected with side plates 8, and the ends of the connecting rods 71 close to the corresponding side plates 8 are fixedly connected with limiting blocks 74. After the workpiece is processed, the output shaft of the motor is reversely rotated to drive the bidirectional screw 12 to reversely rotate, so that the two sets of clamping jaw bodies 4 and the correction auxiliary part 7 move away from the workpiece. When the two correction plates 72 move away from the workpiece, under the rebounding force of the two sets of springs 73, the two correction plates 72 will rebound to the outer ports of the two accommodating cavities 44. When the two sets of limiting blocks 74 contact with the two side plates 8, the two correction plates 72 will be further assisted to reset (after the clamping is completed, the two correction plates 72 are automatically reset in the process that the two sets of clamping jaw bodies 4 move away), so as to prepare for the next correction and centering of the workpiece.

[0046] More specifically, the upper end of one of the clamping jaw bodies 4 is provided with a sliding groove 9, a horizontal sliding block 10 is slidably connected in the sliding groove 9, the sliding groove 9 has a structure of being narrow at the upper end and wide at the lower end, and the horizontal sliding block 10 is horizontally clamped in the sliding groove 9 for sliding.

The protruding end of the pressing plate 113 is provided with a control opening 114, the bottom end of the pressing plate 113 is fixedly connected with an anti-skid pad 116, a bearing is embedded on the side of the upper end of the pressing plate 113 away from the control opening 114, and the bottom end of the transmission screw rod 115 is fixedly connected to the inner ring of the bearing. The horizontal sliding block 10 can slide horizontally in the sliding groove 9, the position of the direction-changing positioning member 11 can be moved according to the processing requirements, then the transmission screw rod 115 is rotated to move the transmission screw rod 115 downward as a whole, and the pressing plate 113 is pushed vertically downward and tightly pressed on the upper end of the workpiece under the guidance of the reverse U-shaped guide rod 112.

[0047] The working principle of the embodiment is as follows: first, the matched placement plate member 6 is installed at the upper end of the support table 5, the table plate 61 is matched with the width of the workpiece to be processed, a suitable supporting area is provided for the workpiece, and the stability of the bottom is improved, and the workpiece to be processed is placed on the upper end of the table plate 61. Here, the workpiece can not be placed in the middle of the upper end of the table plate 61, and can be corrected by the two correction auxiliary members 7 in the application.

[0048] Next, the motor is started to drive the transmission shaft 15 to rotate (the output end of the motor is provided with a speed reducer, and the output shaft of the speed reducer is fixedly connected with the transmission shaft 15). The transmission shaft 15 drives the bidirectional screw rod 12 to rotate, and the bidirectional screw rod 12 drives the two clamping plates 42 to move at a uniform speed. When the two clamping plates 42 move at a uniform speed, the two correction plates 72 will move at a uniform speed (under the condition that the two correction plates 72 are not blocked). When the two correction plates 72 are in contact with the two side walls of the workpiece respectively, the workpiece is pushed to the middle of the placement plate 61 (since the workpiece is not placed directly above the placement plate 61, it may be offset to one side. The correction plate 72 corresponding to the side will push the workpiece to the middle of the placement plate 61. When the two correction plates 72 are in contact with the two side walls of the placement plate 61 respectively, the workpiece is located directly above the placement plate 61). The two clamping plates 42 continue to move closer, and at this time the two correction plates 72 remain stationary (under the action of the rebounding force of the two springs 73, the two correction plates 72 are squeezed into the two accommodating cavities 44). The two clamping plates 42 are clamped on the two side walls of the workpiece, and under the assistance of the two correction plates 72, the two clamping plates 42 and the two side walls of the workpiece are uniformly stressed, so that the two clamping plates 42 and the two side walls of the workpiece are not excessively collided on the side, and the protection effect is achieved in the clamping process. Compared with the traditional vice, the machining protection function is obviously improved, and the clamping machining efficiency of the workpiece is not affected. It should be noted that the vice in the present application is mainly used to clamp semi-finished long strip-shaped plates of different materials. The clamping ends of the two clamping plates 42 are located at the upper end position of the placement plate 61, and can directly abut against and clamp the workpiece. When the workpiece is clamped, the two correction plates 72 abut against the side walls of the placement plate 61, and the upper end of the correction plate 72 protrudes above the placement plate 61, so that the workpiece can be contacted and centered smoothly.

[0049] When the two clamping plates 42 are clamped on the two side walls of the workpiece respectively, the extending end of the pressing plate 113 is located directly above the workpiece. When it is necessary to punch a hole in a certain position of the workpiece, the direction changing positioning piece 11 can be moved to be directly above the position, the pressing plate 113 is moved downward to be tightly pressed on the upper end of the workpiece by rotating the transmission screw 115, and the drilling of the workpiece is completed through the penetrating operation control port 114. The anti-skid pad 116 at the bottom of the pressing plate 113 can play an anti-skid role, effectively preventing the workpiece from shaking slightly, and improving the stability of the machining. The reverse rotation of the transmission screw 115 can end the longitudinal positioning of the workpiece, and the operation is simple and convenient, which improves the machining precision of the workpiece.

[0050] The above specific embodiments are only preferred embodiments of the present application. Based on the technical solutions of the present application and the related inspiration of the above embodiments, those skilled in the art can make various alternative improvements and combinations on the above specific embodiments. The above specific embodiments are only an explanation of the present application, and are not a limitation of the present application.
