The two positioning elements 103 are arranged oppositely. Through such a setting, suitable positioning elements 103 can be selected according to the shape and size of the parts.

[0028] In a possible implementation manner, the vise 300 includes a fixed block 301 and a movable clamp 302. The movable clamp 302 is detachably arranged on both sides of the fixed block 301, and the number of the movable clamps 302 is two.

[0029] Specifically, as Figures 1 to 2 shown, the bench vice 300 includes a fixed block 301 and movable clamps 302. There are two movable clamps 302, which are detachably arranged on both sides of the fixed block 301. Appropriate movable clamps 302 can be selected according to the needs of components.

[0030] In a possible implementation manner, a relief groove matching the positioning element 103 is provided at the edge position of the movable clamp 302 close to the positioning element 103.

[0031] Specifically, as Figures 1 to 2 shown, in order to better clamp components, a relief groove matching the positioning element 103 is provided at the edge of the movable clamp 302 close to the positioning element 103. Appropriate positioning elements 103 and movable clamps 302 can be selected according to the shape or size of the components.

[0033] Specifically, as Figures 3 to 4 shown, since the bench vice 300 needs to move up and down in the through groove 101 driven by the telescopic cylinder 202, the top of the telescopic cylinder 202 is connected to the bottom of the bench vice 300.

[0034] In a possible implementation manner, the base 100 is a cuboid, and a cuboid groove is provided at the bottom of the base 100, and both ends of the cuboid groove penetrate through both ends of the base 100.

[0035] Specifically, as Figures 1 to 2 shown, in order to save space, a cuboid groove is provided at the bottom of the base 100 for placing the driving device 200.

[0036] In a possible implementation manner, a support seat 203 is sleeved outside the motor 201. The size of the support seat 203 matches the cuboid groove provided at the bottom of the base 100; the cuboid groove is also provided at the top of the support seat 203, and the telescopic cylinder 202 is fixedly arranged in the cuboid groove of the support seat 203.

[0037] Specifically, as Figures 1 to 4As shown, in order to enable the driving device 200 to better match the base 100, a support base 203 is sleeved outside the motor 201. A rectangular parallelepiped groove is also provided at the top of the support base 203.

The top of the telescopic cylinder 202 is fixedly connected to the bottom of the vise 300. When the telescopic cylinder 202 extends and retracts up and down, it will drive the vise 300 to move up and down. When the vise 300 moves upward, the space of the positioning groove 102 becomes larger. At this time, place the components on the positioning element 103. After placing the components, the telescopic cylinder 202 drives the vise 300 to move downward, fix the components, and then process or reprocess the components on other devices.

[0039] A positioning groove 102 is opened on the base 100, and a positioning element 103 is detachably arranged in the positioning groove 102. A suitable positioning element 103 can be replaced according to the requirements of the components. A through groove 101 is opened in the middle of the base 100, and a vise 300 is arranged in the through groove 101. The vise 300 is connected to the driving device 200 through the through groove 101. When the vise 300 moves upward, place the components in the positioning element 103, and when the vise 300 moves downward, fix the components. This process realizes the rapid clamping of the components, saves time, improves work efficiency, and the positioning groove 102 is provided in two, that is, a double-station setting. Such a setting enables the present utility model to clamp two components at a time, reduces the number of tool changes, and improves work efficiency.
