Abstract
The invention relates to a pull center press-fitting centring tool which comprises a base. Three locating holes are formed in the lower surface of the base. The center lines of the three locating holes are located in the same plane. A locating rod perpendicular to the lower surface of the base is inserted in each locating hole. By means of the distances between the three locating holes, two of the locating rods are suitable for being inserted into round holes of pull joints, and the other locating rod is suitable for being inserted into a threaded hole of a pull body. The tool capable of enabling different space faces to be converted to the same plane is designed; and in the tool, through the one base, the three holes are formed in the lower surface of the base, and the three locating rods with the sizes matched with those of the round holes in components are embedded in the holes of the base. During use, the three locating rods are inserted into the round holes in the corresponding components, the round holes in the two different planes are converted to the same plane, and then it is guaranteed that the three holes are aligned through locating of the third hole.
Description
Technical field
The present invention relates to a kind of centre of pull and press-fits centering tooling, belongs to rail vehicle truck centre of pull technology of pressure mounting neck
Territory.
Background technology
During existing bogie (as a example by PW-220K) centre of pull press-fits, centre of pull node press-fits skill to be met
Art requires: node and centre of pull four hole will be in the same horizontal line.But owing to press-fiting four holes on the first two parts respectively
It is in Different Plane, therefore simple by visually ensureing that alignment will exist the biggest error.Once press-fit to retrodeviate and moving past stool need
Again to move back and to unload, shirk that process is as easy as rolling off a log causes node to coordinate face to pull with centre of pull, cause cost to waste.Accordingly, it would be desirable to
Design a frock to be transformed on same plane in different faces, space, to solve this difficult problem.
Summary of the invention
The technical problem to be solved is, overcomes the disadvantages mentioned above of prior art, it is provided that a kind of centre of pull pressure
Dress centering tooling, is mainly used in solving traction node and leans on, with centre of pull four hole, the problem that visual collinear error is big.
In order to solve above technical problem, the centre of pull that the present invention provides press-fits centering tooling, it is characterised in that: include
Pedestal, the lower surface of described pedestal offers hole, three location, in the centrage in hole, described three location is generally aligned in the same plane, institute
Stating the location bar that hole, location is inserted into being perpendicular to the lower surface of pedestal, the spacing in hole, described three location makes two therein
Location bar is adapted for insertion into drawing the circular hole of node, and another one location bar is adapted for insertion in traction body screwed hole.
In order to solve above technical problem, the present invention also has the feature that
1, the lower surface of described pedestal is plane, and the centrage place plane in hole, described three location is hung down with the lower surface of pedestal
Directly.
2, described pedestal be cross section be the column structure of rectangle.
3, the described location pole length corresponding with traction body screwed hole is more than the length of other two location bars.
Press-fit centering tooling and carry out, additionally, present invention also offers the described centre of pull of use, the work that centre of pull press-fits
Skill, step is as follows:
1st step, traction body is put into pressing machine；
2nd step, by traction node be placed in the centre bore of traction body；
3rd step, by two location bars of described frock respectively insert traction node node holes in；
4th step, rotation traction node, be that the head of an other location bar inserts traction body screwed hole；
5th step, extract described frock out；
6th step, utilize pressing machine will traction node press-in traction body in.
The present invention devises a frock that can realize being transformed on same plane different faces, space, and this frock is led to
Cross 1 pedestal, open three holes at pedestal lower surface, the location bar that three are closed with circular hole matching size on parts is embedded pedestal
In hole.During use, three location bars are inserted in the circular hole on corresponding component, the circular hole in two Different Plane is transformed into same
One unilateral on, then by the 3rd hole position assurance three hole being aligned.
Accompanying drawing explanation
The present invention is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is that centre of pull of the present invention press-fits centering tooling structural representation.
Fig. 2 is the side view of Fig. 1.
Fig. 3 is the use schematic diagram that centre of pull press-fits centering tooling.
Detailed description of the invention
As shown in Figure 1 and Figure 2, press-fit centering tooling for centre of pull,
It is characterized in that: include pedestal 1, pedestal 1 be cross section be the column structure of rectangle, the lower surface of pedestal 1 offers three
Hole, location, in the centrage in hole, three location is generally aligned in the same plane and vertical with the lower surface of pedestal 1, hole, location is inserted into
The a positioning rod 2, second having the lower surface being perpendicular to pedestal 1 positions bar 3 and the 3rd location bar 4, the spacing in hole, three location
Making a positioning rod 2, second therein position bar 3 and be adapted for insertion into drawing the circular hole of node 5, the 3rd location bar 4 is suitable for
Insert in the screwed hole of traction body 6.
As it is shown on figure 3, be the use view of frock of the present invention.The present embodiment centre of pull is used to press-fit centering work
Putting into the technique that row centre of pull press-fits, step is as follows:
1st step, traction body 6 is put into pressing machine；
2nd step, by traction node 5 be placed in the centre bore of traction body 6；
3rd step, a positioning rod 2, second of frock is positioned bar 3 inserts respectively in the node holes drawing node 5；
4th step, rotation traction node 5, be the screwed hole of the head insertion traction body 6 of the 3rd location bar 4；
5th step, extract described frock out；
6th step, utilize pressing machine will traction node press-in traction body in.
Present configuration is the most easy to use, it is possible to quickly realize the location of location node, improves efficiency of assembling and assembling
Quality, it is to avoid owing to being visually directed at the error caused.
In addition to the implementation, the present invention can also have other embodiments.All employing equivalents or equivalent transformation shape
The technical scheme become, all falls within the protection domain of application claims.
