[0011] Figure 1 It is a schematic structural diagram of the part clamping and positioning device of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0012] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0013] Please refer to Figure 1 , a part clamping and positioning device of the present utility model includes: a base 1, two groups of support columns 2 symmetrically arranged on the base, a fixed table support seat 3 arranged on the support columns, a product fixed table 4 arranged on the fixed table support seat, drive cylinders 5 arranged on both sides of the support columns on the base, and a claw mechanism for pressing the part to be machined. Among them, a cavity for placing the part to be machined is arranged in the product fixed table. A spring positioning bead 6 for positioning the part to be machined is arranged on the side of the cavity in the product fixed table. The spring positioning beads are evenly distributed circumferentially around the cavity, and the number is 3 - 5 groups. It is convenient and fast to load and unload the part to be machined, and will not scratch the part to be machined. It can fix the product and prevent left - right deviation during the machining process. In addition, the cavity of the product fixed table can be switched and designed according to the model of the part to be machined.
[0014] Specifically, the claw pressing mechanism includes a fixed claw 7, a claw linkage block 8 fixedly connected to the fixed claw, and a linkage support rod assembly. The lower end of the linkage support rod assembly is rotatably connected to a connecting rod fixed seat on the driving cylinder. The upper end of the linkage support rod assembly is rotatably connected to the claw linkage block. The power output end of the driving cylinder is rotatably connected to the end of the claw linkage block.
