Embodiment Construction

[0015] see Figure 2-3 The shown mobile block drilling top hole fixture includes a vise 9 and a drilling mold 2 clamped by the vise. The drilling mold is provided with a cylindrical hole 3 corresponding to the cylinder of the moving block, and there are protrusions on the bottom surface of the cylindrical hole. Corresponding quadrangular prism 4 with the square hole of moving block.

[0016] see Figure 4-7 , the drilling mold is composed of an upper drilling mold 5 and a lower drilling mold 6. The upper drilling mold is an upper plate with a cylindrical hole 3 and a guide hole 8. The guide hole 8 is perpendicular to the cylindrical hole and is used for drilling side holes. Pass. The lower drilling jig is a lower plate with the quadrangular prism 4 protruding from the surface; the upper plate and the lower plate are positioned by two pins passing through two pin holes 7 and connected by two bolts.

[0017] The upward drilling template of cylindrical hole 3 is clamped by vic...

Abstract

The invention provides a clamp for drilling a top hole in a moving block. The clamp for drilling the top hole in the moving block is high in locating accuracy and convenient to use. The moving block is a cylinder with a square hole in the bottom and the top hole in the top, the top hole and the square hole are coaxial, and a side hole perpendicular to a round hole is formed in the side face of the cylinder. The clamp for drilling the top hole in the moving block comprises a jaw vice and a drill jig clamped by the jaw vice, a cylindrical hole corresponding to the cylinder is formed in the drill jig, and a quadrangular prism corresponding to the square hole is arranged on the bottom face of the cylindrical hole in a protruding mode.

Description

technical field [0001] The technology relates to a drilling jig, in particular, a jig for drilling top holes on a moving block. Background technique [0002] see figure 1 Shown mobile block 1 is a cylinder with a square hole 11 at the top and a top hole 12 at the top. The top hole is coaxial with the square hole, and the side hole 13 perpendicular to the circular hole is provided on the side of the cylinder. [0003] This moving block is to process the square hole earlier, and then drills the top hole 12 or the side hole 13. Previously, there was no dedicated fixture, resulting in low positional accuracy of drilled top or side holes. Contents of the invention [0004] The purpose of this technology is to provide a jig with high positioning accuracy and convenient use for drilling top holes with moving blocks. [0005] This moving block drills the top hole jig, the moving block is a cylinder with a square hole at the bottom and a top hole at the top, the top hole is coax...
