Abstract
The utility model provides a hole extrusion clamp. The hole extrusion clamp comprises a base, a lower locating plate, a tungsten steel ball, a ball pressing column, an upper locating plate and a pressing machine. The lower locating plate is installed on the base through bolts in a fastening mode, and the base is provided with a flow channel. The lower locating plate is provided with a work-piece groove used for containing a work-piece, and a through hole is formed in the lower portion of the work-piece groove and communicated with the flow channel. The work-piece is installed inside the work-piece groove. The tungsten steel ball is arranged above the work-piece and corresponds to a hole to be machined in the work-piece in position. The ball pressing column is arranged above the tungsten steel ball, is used for exerting pressure on the tungsten steel ball and is connected with the pressing machine through the upper locating plate in a fastening mode. According to the hole extrusion clamp, the tungsten steel ball is placed between the work-piece and the ball pressing column, is pressed downwards and then enters the hole to be machined in the work-piece under the downward acting force of the pressing machine, and therefore machining of an inner hole of the work-piece is achieved. The hole extrusion clamp is simple in structure, convenient to operate, low in labor intensity, high in efficiency, and capable of lowering the rejection rate obviously.
Description
Technical field
The utility model belongs to the fixture field, is specifically related to a kind of crowded hole fixture.
Background technology
The batch production of high accuracy, low surface roughness steel components aperture, the processing mode that generally all adopts hand drill, expansion, cuts with scissors, grinds, long but the shortcoming of these processing modes is operations, labour intensity is large, and environmental sanitation is poor, and percent defective is high, and cost is high.
The utility model content
The utility model provides a kind of crowded hole fixture of the rate of can obviously reducing the number of rejects and seconds for above-mentioned the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
A kind of crowded hole fixture comprises base, lower location-plate, wolfram steel ball, pressure ball post, upper location-plate and press, and lower location-plate is arranged on base by bolted, is provided with runner on base; Offer the workpiece groove for accommodating workpiece on lower location-plate, workpiece groove bottom is provided with through hole, and described through hole is communicated with runner; Workpiece is arranged in the workpiece groove; The wolfram steel ball is arranged on the top of workpiece, and is corresponding with the hole site to be processed on workpiece; The pressure ball post is arranged on the top of steel ball, is used for exerting pressure to steel ball; The pressure ball post is fastenedly connected by upper location-plate and press.
Preferably, described pressure ball post and upper location-plate are fastenedly connected by a plurality of interior hexagonal fastening bolts.
Preferably, described upper location-plate and press are fastenedly connected by a plurality of outer-hexagonal fastening bolts.
Crowded hole described in the utility model fixture is by being placed on the wolfram steel ball between workpiece and pressure ball post, and the downward active force of press, make the wolfram steel ball press down to enter in the hole to be processed on workpiece, thereby realized the processing to inner hole of workpiece, more than the inner bore surface roughness of workpiece behind crowded hole can improve two-stage.This squeezes, and the hole clamp structure is simple, easy to operate, labour intensity is low, efficient is high, the rate of can obviously reducing the number of rejects and seconds.
