Detailed description of the invention
Below, in conjunction with example, substantive distinguishing features of the present utility model and advantage are further described, but this practicality is new
Type is not limited to listed embodiment.
As shown in Figures 1 to 6, the U-shaped fixture of single axle 100 of the present embodiment includes clamp body 1, drives assembly and processing group
Part, described driving assembly and processing assembly are arranged on clamp body 1, by driving assembly to drive processing assembly to add workpiece
Work.Described processing assembly includes U-shaped piece 2, U-shaped cushion block 3 and briquetting 4, and described U-shaped piece 2 and U-shaped cushion block 3 are respectively equipped with first
Half slot 21 and the second half slot 31, U-shaped cushion block is arranged in described first half slot 21.Described U-shaped cushion block 3 upper surface is provided with
The briquetting 4 floated.Described driving assembly includes lever 5 and pressing plate 6, and lever 5 is connected with pressing plate 6, and lever 5 can be transported by band dynamic pressure plate 6
Dynamic.The U-shaped fixture of single axle of technique scheme is when machining crankshafts, and crank rod portion is put in the of U-shaped piece 2 and U-shaped cushion block 3
One, on the second half slot, after crankshaft pin accurate positioning, by driving assembly to drive lever 5 so that pressing plate 6 workpiece pressing
