Abstract

The utility model relates to a dedicated fixture for drilling holes, which comprises a fixture main part, wherein an erect supporting plate is hinged on a baseplate of the fixture main part, a horizontal locating rod is placed on the supporting plate, one end of the horizontal locating rod is inserted to a vertical plate of the fixture main part, an erect locating rod is mounted on a top plate of the fixture main part arranged above the horizontal locating rod, and a positioning reference block and a set of erect drilling jigs are arranged on both the two sides of the erect locating rod. The novel jig has the advantages of reasonable design and convenient use, is suit crankshaft products with multiple holes and the same drill, and can shorten drilling time, improve production efficiency and processing precision, and ensure workpiece quality.

Description

The boring special fixture

Technical field

The utility model relates to and grips apparatus field, especially a kind of boring special fixture that is applicable to that the crankshaft type product uses.

Background technology

When at present workpiece being punched a hole, usually all adopt traditional single hole list drill method, concerning the workpiece that needs to process a plurality of holes thereon, this traditional processing mode exists long processing time, working (machining) efficiency is low, clamping speed slow, process defectives such as the back workpiece accuracy is low, can not satisfy the needs of modern production.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and providing a kind of can enhance productivity, and shortens process time and clamping time, guarantees the boring special fixture that workpiece quality is good, precision is high.

The utility model solves its technical problem and is achieved through the following technical solutions:

A kind of boring special fixture, comprise a jig main body, it is characterized in that: hinge is adorned a vertical supporting plate on the base plate of jig main body, put a horizontal location bar on this supporting plate, one end of this horizontal location bar is inserted on the vertical plate of jig main body, be positioned on the top board of jig main body of horizontal location bar top a vertical backstay is installed, these vertical backstay both sides all are provided with simultaneously locatees reference block and one group of vertical drill jig.

And described horizontal location bar is made one handle away from an end of vertical plate.

And set drill jig is four on the described jig main body top board.

Advantage of the present utility model and beneficial effect are:

1, this boring special fixture adopts four drill jigs is set on the jig main body above the workpiece to be processed, and therefore clamping can be finished the bore process of four road diverse locations simultaneously, has both reduced clamping times, satisfies the degree requirement of a plurality of positions again.

2, this boring special fixture process velocity is fast, and the precision height is easy to adjust, can increase work efficiency 4 times.

3, the utility model is a novel clamp a kind of reasonable in design, easy to use, is fit to porous and uses with the crankshaft type product that bores, and uses these anchor clamps can shorten drilling time, enhances productivity, improves machining accuracy, guarantees workpiece quality.
