[0006] The utility model is a laser engraving positioning fixture, comprising a support frame, a fixture body and a workpiece body, a fixture groove is provided inside the support frame, the fixture body is arranged in the fixture groove and rotatably cooperates with the fixture groove, the fixture body is circular, a through groove is provided at the top of the support frame, the through groove is communicated with the fixture groove, a plurality of positioning holes are evenly distributed on the circumferential side surface of the fixture body, an insertion rod is inserted into the interior of the through groove, one end of the insertion rod is plugged into the positioning hole, and the other end of the insertion rod is fixedly connected to a connecting head, the connecting head is arranged on the outside of the through groove, a plurality of screw holes are evenly distributed on one surface of the fixture body, the internal threads of the screw holes are connected to positioning screws, and the circumferential side surface of the positioning screws is conical.

[0007] A matching rod is fixedly connected to one side of the clamp body, and a profiled positioning block is slidably connected to the circumference of the matching rod. A limiting rod is inserted into one end of the matching rod, and the limiting rod is attached to one side of the profiled positioning block. The shape of the profiled positioning block is adapted to the shape of one side of the workpiece body.

[0008] The bottom end of the support frame is fixedly connected to a base plate, and fixing screws are provided on both sides of the inside of the base plate; this facilitates fixing the support frame and improves the stability of the support frame when working.

[0009] The size of one end of the workpiece body is smaller than that of the fixture slot, and fixing holes are provided on both sides of one end of the workpiece body; one end of the workpiece body can be positioned and fixed to the fixture body, which is convenient for engraving operations.

[0010] The utility model has the following beneficial effects:

[0011] The utility model provides a clamp body, an insertion rod, a positioning screw and a profiling positioning block. When the workpiece body is engraved, one end of the workpiece body is attached to the clamp body, and under the action of the profiling positioning block, the workpiece body is positioned so that the fixing hole on the workpiece body is aligned with the screw hole on the clamp body, and then the positioning screw is screwed into the fixing hole and the screw hole. Because the peripheral side surface of the positioning screw is tapered, as the positioning screw is screwed in, it limits and fixes the workpiece body, thereby completing the fixation of the workpiece body and facilitating subsequent engraving operations; pulling the connecting head can release the restriction of the insertion rod and the positioning hole, and then the clamp body can be rotated, so that it drives the workpiece body to rotate, so that multiple surfaces of the workpiece body can be operated. After rotating to the appropriate position, the clamp body is fixed by plugging the insertion rod into the positioning hole. The utility model has a simple structure and is easy to use.

[0012] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
