Embodiment 1

[0021] see Figure 1~6 , a drilling jig, specially used for processing specified pin shaft parts, is a special jig for specific parts. The specific structure of the pin shaft part can refer to the accompanying drawings for the structural form. A drilling fixture is composed of a V-shaped positioning block 01, a fixed base plate 03, a support base plate 17, a first drilling assembly, a second drilling assembly, a pressing plate assembly, a support pin assembly, and a support screw assembly. The V-shaped positioning block is L-shaped, and a V-shaped positioning surface 43 is arranged on the upper end surface of the L-shaped short side of the V-shaped positioning block. Positioning surface C, the axis of the V-shaped positioning surface is perpendicular to the positioning surface C, the V-shaped positioning block is fixed on the fixed base plate through a screw structure, and the fixed base plate is vertically fixed on the fixed base plate through a screw structure. On the supp...

Abstract

The invention relates to a drilling clamp. The drilling clamp is composed of a V-shaped positioning block, a fixed bottom plate, a supporting bottom plate, a first drilling assembly, a second drillingassembly, a pressing plate assembly, a supporting pin assembly and a supporting screw assembly, the V-shaped positioning block is in an L shape, a V-shaped positioning face is arranged on the upper end face of the L-shaped short edge of the V-shaped positioning block, and meanwhile a positioning face C is arranged on the V-shaped positioning block; the V-shaped positioning block is fixed to the fixed bottom plate through a screw pin structure, the fixed bottom plate is vertically fixed to the supporting bottom plate through a screw pin structure, and the first drilling assembly is composed ofa first drill plate, a first drill sleeve, a first hinge sleeve and a first locking screw; and the first drill plate is fixed to the upper end face of the fixed bottom plate through a screw pin structure, the second drilling assembly is composed of a second drill plate, a second drill sleeve, a second hinge sleeve and a second locking screw, the supporting pin assembly is composed of a supportingpin and a jacking screw, and the supporting screw assembly is composed of a supporting screw and a supporting disc. According to the drilling clamp special for a drilling machine, the product processing stability can be improved, the product machining rejection rate is decreased, and the product machining cost is reduced.

Description

technical field [0001] The invention relates to a drilling jig, in particular to a high-precision drilling jig for a drilling machine. Background technique [0002] With the continuous development of CNC machine tool technology, the use of high-precision CNC machine tools and turning-milling compound machining centers is becoming more and more popular. For complex turning and grinding parts, such as pins and bolts, the turning and milling compound center is a more suitable processing equipment. However, for complex turning and grinding parts, if there is a higher precision hole position requirement on the part, higher requirements are placed on the accuracy of the machine tool and cutting tools, which will lead to a relative increase in processing costs. Therefore, the design and manufacture of special fixtures is usually an extremely effective means of realization for mass-produced and difficult-to-manufacture turning and grinding parts. [0003] The present invention is ...
