The invention belongs to the technical field of tooling equipment and provides a fixing device for a workpiece. The fixing device comprises a base, wherein the base is provided with a lug boss which is inserted into a hole formed in the workpiece; a thread hole is formed in the top of the lug boss; a wedge is further inserted into the hole; the wedge is at least detached into two structures alongthe peripheral direction; the outer diameter of the wedge is the same as the inner diameter of the hole; a tapered hole with a big top and a small bottom is formed in the wedge; a tapered sleeve is inserted into the tapered hole; a pressing plate is arranged above the tapered sleeve; and when a bolt penetrates through the pressing plate and the tapered sleeve in sequence and then is screwed into the thread hole, an inner wall of the hole is tightly pressed by the periphery of the wedge, so that the technical problem that an existing workpiece with a special shape is difficult to fix by utilizing a clamping device is solved.
Description
technical field [0001] The invention belongs to the technical field of tooling equipment, and relates to a workpiece fixing device. Background technique [0002] Some cast workpieces have special shapes and are difficult to fix in further drilling and other processing procedures, such as Figure 7 The workpiece 13 shown is a workpiece that is relatively difficult to fix, and a hole 3 is arranged on it. The hole 3 is a square hole, and it is difficult to achieve a good fixation with the existing clamping device. Contents of the invention [0003] The invention provides a workpiece fixing device, which solves the above technical problems. [0004] Technical scheme of the present invention is realized like this: [0005] A fixture for workpieces, comprising: [0006] A base, the base is provided with a boss for inserting into a hole on the workpiece, the top of the boss is provided with a threaded hole, and a wedge is inserted into the hole, and the wedge is at least detach...
