Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1~4 A V-shaped block positioning fixture shown includes a clamp body 1, two V-shaped blocks 2, and a pad 3, and the two V-shaped blocks 2 are symmetrically arranged at both ends of the clamp body 1, and the pads 3 is installed on the V-shaped groove surface 21 of the V-shaped block 2.

[0022] Specifically, the V-groove surface 21 is provided with a threaded hole 22, and the pad 3 is provided with a counterbore 31 matching the threaded hole 22, and the pad 3 is installed on the V-shaped groove surface 21 through a hexagon socket head cap screw 5. On the V-shaped groove surface 21. A step 4 is arranged on the V-shaped groove surface 21 , and the spacer 3 is arranged on the surface of the step 4 . The V-shaped block 2 is a stepped integral structure with left-right center symmetry. The thickness of the pad 3 is 10-100mm.

Abstract

The invention provides a V-shaped-block locating clamp comprising a clamp body, two V-shaped blocks and cushion blocks. The two V-shaped blocks are symmetrically arranged at the two ends of the clamp body. The cushion blocks are installed on V-shaped groove faces of the V-shaped blocks. According to the V-shaped-block locating clamp, it is only needed to replace cushion blocks of different thicknesses, and then step shafts of different diameters can be located; the V-shaped-block locating clamp is widely used for clamping workpieces with the two ends having different shaft diameters, the height of each shaft end can be rapidly and accurately adjusted through replacement of the cushion blocks on the V-shaped blocks, and the phenomenon that the height of the V-shaped blocks is changed due to shake during machining can be effectively avoided; the V-shaped-block locating clamp is small in structure volume, good in overall system rigidity, wide in adjustment range, high in locating precision and wide in application range.

Description

technical field [0001] The invention belongs to the field of machine tool fixtures, and in particular relates to a V-shaped block positioning fixture. Background technique [0002] V-shaped block is a commonly used device in the field of machining, and is generally used for positioning and clamping cylinders. The traditional manufacturing method of the V-shaped block is generally the overall manufacturing, and the final finishing of the two slopes is often completed on a surface grinder using a precision sinusoidal fixture and a V-shaped guide magnet. However, the symmetry of the working slope of this V-shaped block is difficult to guarantee an ideal state. [0003] V-shaped blocks are frequently used in mechanical processing places. V-shaped blocks are standard parts, and the angle and size are fixed, so the angle and size of a single V-shaped block cannot be adjusted. When the V-shaped block is used in the production of diesel engine exhaust pipe parts, with the rapid re...
