Problems solved by technology

In practical applications, several positioning methods are often combined. For example, the positioning of the blank hole and the blank surface is often used in combination. However, due to large errors in the size and roundness of the blank hole, the positioning error is large and the processing quality of the workpiece not easy to guarantee

Embodiment Construction

[0018] The present invention will be further described below in conjunction with accompanying drawing:

[0019] Such as figure 1 , figure 2 , image 3 As shown, a mechanical processing positioning device includes a base 1, an adjustable support assembly and an adjustable clamping mechanism arranged on the base 1. The base 1 is provided with a cylindrical inner cavity 2 and a stepped channel with an inner wall. The hole 3, the inner cavity 2 runs through the bottom of the base 1, and the top of the inner cavity 2 is a circular hole 4, the diameter of the circular hole 4 is smaller than the diameter of the cylindrical inner cavity 2;

[0020] The adjustment support assembly includes a cylindrical taper pin 5 arranged in the inner cavity 2, a compression spring A6 and a screw plug 7 arranged below the cylindrical taper pin 5 in turn, and the cylindrical taper pin 5 includes a cone front 8 and a cylinder rear Part 9, the front part 8 of the cone protrudes from the hole 4 at th...

Abstract

The invention disclose a mechanical processing positioning device, which comprises a base (1), an adjusting support assembly and an adjustable clamping mechanism, wherein the adjusting support assembly comprises a cylindrical taper pin (5), a compression spring A (6) and a screw plug (7), the cylindrical taper pin (5) is arranged in an inner cavity (2), the adjustable clamping mechanism comprises an adjusting screw rod (10), a press plate (11) and a compression spring B (12), the press plate (11) and the compression spring B (12) are sheathed outside the adjusting screw rod (10), and the adjusting screw rod (10) penetrates through a through hole (3) arranged on the base (1) and is fixed by a locking screw bolt (16). The mechanical processing positioning device has the beneficial effects that the diameter of the large end of a cone front part (8) is greater than the diameter of a blank hole, the wider positioning range is realized, the cylindrical taper pin (5) is tightly matched with the blank hole by the adjusting support assembly via the extension and retraction of the compression spring A (6), the influence of size and roundness errors of the blank hole can be overcome, the matching clearance is eliminated, and the positioning error is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of blank positioning devices in machining, in particular to a machining positioning device for rough reference positioning of blanks. Background technique [0002] In the mechanical processing and manufacturing industry, the positioning device plays a very important role. It ensures that the workpiece is always in the correct position relative to the machine tool, cutting tool, etc., and ensures the consistency and quality of the workpiece processing. In mechanical processing, many processes are required from the blank to the finished product. The positioning methods of each process are various, but they can be summarized into two types: rough reference positioning and fine reference positioning. Coarse datum positioning is divided into blank shape positioning, blank hole positioning, and blank surface positioning. In practical applications, several positioning methods are often combined. For example, the p...
