Abstract

The invention discloses a fixture structure, which is used for clamping a stepped workpiece having a rectangular groove or a semicircular groove. The fixture structure is arranged on a CNC milling machine, and comprises a base, washers and set screws, wherein the base is provided with a top surface, a bottom surface, a left side surface, a right side surface, a front surface and a back surface, the top surface is provided with a workpiece groove, and a workpiece is clamped in the workpiece groove; the washers are respectively arranged at the bottom surface, the left side surface, the right side surface, the front surface and the back surface; certain ends of the set screws are fixed onto the washers, and the other ends of the set screws are free ends. By adoption of the structure, the stepped workpiece having the rectangular groove or the semicircular groove can be obtained through the CNC milling machine. Hence, through the steps, the meter calibration time in the field can be saved, and the processing efficiency is high; a wire cutting processing is not needed, so that the processing cost is low; a special chamfering tool is not needed, so the processing cost brought by the tool is reduced.

Description

【Technical field】 [0001] The invention relates to the field of machining, in particular to a fixture structure used in machining. 【Background technique】 [0002] see figure 1 , figure 1 It is a schematic diagram of a workpiece structure. As shown in the figure, the workpiece 101 can be processed by a rectangular block, the workpiece 101 is basically in the shape of a step, one of the opposite sides of the workpiece 101 has a rectangular groove 102, and the other opposite side of the workpiece 101 A semicircular groove 103 is opened on the side. [0003] To process the above-mentioned workpiece 101 in the prior art, a CNC numerical control milling machine can be used to process the rectangular block at first to mill out the step shape, and then the rectangular groove 102 can be processed by the wire cutting process. For the semicircular groove 103, a special Tool for processing. The use of the above process requires a number of different manufacturing processes, so on-si...
