Detailed Description
The utility model is described in further detail below with reference to the drawings and the detailed description.
Referring to fig. 1-6, a positioning fixture for polishing a workpiece in specific implementation of the embodiment of the utility model comprises a fixing seat 1 and a fixing piece 2, wherein a cavity 101 for accommodating a workpiece 5 is arranged on the fixing seat 1, angle limiting grooves 102 are formed in two ends of the cavity 101, the fixing piece 2 is installed in the cavity 101 through angle limiting pieces 3, two ends of the angle limiting pieces 3 are embedded in the angle limiting grooves 102, one end of the angle limiting grooves 102 is communicated with the outside, the cross section of the angle limiting pieces 3 is square, and the angle limiting pieces 3 protrude out of the angle limiting grooves 102.
Further, the cross section of the angle limiting member 3 may be a regular triangle, a regular pentagon, a regular polygon, or a polygon, so as to be adapted to the workpiece 5, so as to polish a plurality of outer surfaces of the workpiece 5, and one side of the cavity 101 is open.
Further, one end of the angle limiting groove 102 is communicated with the outside through the opening 103, the width of the opening 103 is larger than that of the angle limiting groove 102, an arc surface used for guiding is arranged at the joint of the opening 103 and the angle limiting groove 102, and the arrangement of the opening 103 and the arc surface is beneficial to the disassembly and assembly of the angle limiting piece 3.
Furthermore, the outer side of the fixing piece 2 is embedded and provided with an anti-slip adhesive tape 4, and the arrangement of the anti-slip adhesive tape 4 can form certain resistance to the sleeved workpieces 5, so that the workpieces 5 cannot be scattered in the process of disassembly and adjustment.
Further, the fixing base 1 is mounted in a matched manner with the outside through a screw and a bolt, and a threaded hole 104 and a bolt positioning hole 105 are formed in the fixing base 1.
The protruding improvement points of the clamp are as follows: the positioning clamp is suitable for polishing a part of workpiece 5 with a regular shape, for example, the workpiece 5 with a square cross section shape in the embodiment, and the positions to be polished are on four surfaces on the outer side of the workpiece 5, so that the positioning clamp can be used, after polishing of one surface is completed, the angle limiting part 3, the fixing part 2 and the workpiece 5 can be quickly taken out of the angle limiting groove 102, and the workpiece 5 is rotated to the next processing surface and then is installed into the angle limiting groove 102, so that the surface to be processed of the workpiece 5 is always parallel to a grinding machine, and the polishing precision of the workpiece 5 is controlled.
