Description

Automobile hub bearing is pressed nail die device down

Technical field

The utility model relates to a kind of automobile hub bearing and presses nail die device down, is used for press-fiting simultaneously a plurality of screws of automobile hub bearing.

Background technology

At present, automobile hub bearing presses the processing method of screw to have following two kinds:

First kind is that single screw press-fits.On counterdie, be provided with a cannelure, during work, earlier with being placed on the counterdie after screw and the automobile hub bearing combination; Primer fluid press then; Seaming chuck is moved down, and seaming chuck press-fits single screw, and extrusion screw and automobile hub bearing firmly link together.Because the effect of pressure, the installed surface of screw deforms easily, and on the installed surface of automobile hub bearing, impression occurs, and it is overproof that the installed surface of automobile hub bearing is beated, and position degree and outward appearance between many screws are overproof.Simultaneously, because employing is that single screw press-fits, production efficiency is extremely low.

Second kind is that many screws press-fit simultaneously.On the counterdie of pressing die device under the nail, be provided with a plurality of screw locating holes, when seaming chuck drive upper mould device moves down, push a plurality of screws and automobile hub bearing simultaneously and firmly link together.Because other factorses such as product and technologies, the screw radial location is not accurate, press-fits in the process at screw, and the screw thread of screw is easily by the counterdie scratch, and the position degree between while many screws is overproof, also can produce impression on the installed surface of automobile hub bearing.

Press the defective of nail mode to be for existing two kinds: the assembling weak effect, the installed surface of automobile hub bearing has impression, and the quality of product can not get guaranteeing that the Assembling Production efficient of automobile hub bearing is low, is not suitable for requirements of mass production.

The utility model content

The screw thread that impression and screw appear in the installed surface that the utility model technical problem to be solved is to provide a kind of can effectively enhance productivity, prevent automobile hub bearing is by the pressure of scratch nail die device down.

The technical scheme of the utility model is following: a kind of automobile hub bearing is pressed nail die device down; On counterdie (1), have centre bore (1a) and a plurality of locating hole (1b); Said locating hole (1b) is surrounded on the periphery of centre bore (1a); Its key is: said locating hole (1b) is up-small and down-big stepped hole, is made up of last diameter segment and following diameter segment, in the following diameter segment of locating hole (1b), is provided with location jacking block (2) and spring (3); The upper end of said location jacking block (2) is spacing by the step surface in the locating hole (1b); The lower end of location jacking block (2) and the upper end butt of spring (3), the lower end of spring (3) and lower bolster (4) connect, and said lower bolster (4) is fixed on the bottom of counterdie (1).

The utility model is designed to step with the locating hole on the counterdie; And location jacking block and spring be set in each locating hole; Press-fit like this in the process of operation; The installed surface of automobile hub bearing contact with the counterdie upper surface stressed before, lean on many screws moving vertically downward with automobile hub bearing rotation location automatically radially, the accurate location when guaranteeing that each screw press-fits.Drive to press at seaming chuck and to nail on when retracting on the mould; Automobile hub bearing under the spring force effect, return vertically upward, the installed surface of automobile hub bearing leaves counterdie; Both guaranteed that screw was not damaged by counterdie, guaranteed again that the position degree of automobile hub bearing screw was qualified.This shows that the utility model has effectively prevented impression to occur on the installed surface of automobile hub bearing and damage appears in screw thread, and press before and after the screw, hub bearing put into take out simple, flexibly, convenient; The utility model can carry out press-fiting of many screws simultaneously, has guaranteed product quality, has improved production efficiency greatly.

In order to make the location jacking block move up and down smooth and easy; And help the automobile hub bearing screw is located; Matched in clearance between said location jacking block (2) and the counterdie (1) has locating slot (2a) at the top of location jacking block (2), and this locating slot (2a) is over against the reduced diameter section of locating hole (1b).

As preferably; Said lower bolster (4) fixes through many screws and counterdie (1); The position of going up corresponding locating hole (1b) at lower bolster (4) has blind hole; The shape of this blind hole size is identical with the enlarged diameter section of locating hole (1b), and the lower end of said spring (3) is stretched in this blind hole, and connects with the interior diapire of blind hole.

Beneficial effect: the utility model efficiently solves automobile hub bearing and presses screw thread damage, the threaded end of the installation end face impression of nail process generation, screw to jump problems such as defective; Improved production efficiency greatly; Guaranteed consistency of product, solved automobile hub bearing and pressed the production bottleneck of following closely.

Description of drawings

Fig. 1 is the structural representation of the utility model.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described further:

As shown in Figure 1, the utility model is made up of counterdie 1, location jacking block 2, spring 3 and lower bolster 4.Wherein, lower bolster 4 is a slab construction, places counterdie 1 at the upper face of lower bolster 4, fixes through many screws that wear from lower to upper between the two.Center at said counterdie 1 offers centre bore 1a along its direction of axis line; And be provided with a plurality of locating hole 1b in the periphery of centre bore 1a; Said centre bore 1a and locating hole 1b all connect the upper and lower end face of counterdie 1; The number of locating hole 1b and arrangement are corresponding with the screw position on the automobile hub bearing, do not do at this and give unnecessary details.

As shown in Figure 1; Locating hole 1b is up-small and down-big stepped hole; Form by last diameter segment and following diameter segment, in the following diameter segment of locating hole 1b, be disposed with location jacking block 2 and spring 3, matched in clearance between said location jacking block 2 and the counterdie 1 from top to bottom; The top of jacking block 2 has locating slot 2a in the location, and this locating slot 2a is over against the reduced diameter section of locating hole 1b.The upper end of said location jacking block 2 is spacing by the step surface in the locating hole 1b, the lower end of location jacking block 2 and the upper end butt of spring 3.The position of corresponding locating hole 1b has blind hole on lower bolster 4, and the shape of this blind hole size is identical with the enlarged diameter section of locating hole 1b, and the lower end of said spring 3 is stretched in this blind hole, and connects with the interior diapire of blind hole.

The operation principle of the utility model is following:

Earlier automobile hub bearing is positioned over the upper surface of counterdie 1, then places screw, make screw pass the installing hole of automobile hub bearing; And with the little matched in clearance of locating slot 2a at jacking block 2 tops, location; Open hydraulic press then, seaming chuck drive to be pressed nail on mould to move down, in case screw stressed just with location jacking block 2 together; Overcome motion vertically downward behind the elastic force of spring 3; The installed surface of automobile hub bearing contact with counterdie 1 upper surface stressed before, lean on many screws moving vertically downward with automobile hub bearing rotation location automatically radially, the accurate location when guaranteeing that each screw press-fits.Be press-fit into place, press to nail on when retracting on the mould, automobile hub bearing is under the elastic force effect of spring 3; Return vertically upward; The installed surface of automobile hub bearing leaves counterdie 1, has both guaranteed that screw is not damaged by counterdie, has guaranteed that again the position degree of hub bearing screw is qualified.
