Detailed Description
The utility model is further described by the following detailed description in conjunction with the accompanying drawings.
Example 1:
as shown in fig. 1 to 3, a work holder includes a base 1. The base 1 is provided with a slide rail 4, the slide rail 4 is connected with a slide block 5 in a sliding manner, and the slide block 5 is fixedly provided with a movable base 2. The movable base 2 has a plate-like structure. The movable seat 2 is horizontally arranged. The movable base 2 can move along the direction of the slide rail. The moving seat 2 is provided with a positioning mechanism for positioning a workpiece, and the positioning mechanism comprises a first positioning pin 9 and a second positioning pin 10 which are arranged on the moving seat 2. The movable seat 2 is fixedly provided with a side plate 3. The side plate 3 is perpendicular to the movable base 2. The side plate 3 is provided with a side stopper 13.
The both sides of removing the seat are provided with mount pad 6 and fixing base 11 respectively, and mount pad 6 and fixing base 11 are all fixed on base 1. The mounting seat 6 is provided with a driving device for driving the movable seat to move along the sliding rail. The drive means comprise an upper telescopic drive 7 and a lower telescopic drive 8. One end of the lower telescopic driving device 8 is fixed on the mounting seat 6, and the other end is connected with the movable seat 2. One end of the upper telescopic driving device 7 is fixed on the mounting seat 6, and the other end is connected with the side plate 3. In this embodiment, the first telescopic driving device and the second telescopic driving device are both cylinders. The fixed base 11 is provided with a side positioning pin 12 for positioning a workpiece.
