Change development, rail traffic shows more and more types, be not only dispersed throughout the land transport of long range, is also widely used in
In short-range urban public transport.
Wherein in the connecting rod of subway train, generally requires to reduce abrasion and use bushing, simultaneously because chassis portion
It needs to keep smooth with top, bushing is the angle using 2.5 degree of band, therefore can face problem difficult to load and unload.
Utility model content
The purpose of this utility model is exactly to provide a kind of band angle lining to overcome the problems of the above-mentioned prior art
Set assembly and disassembling fixture.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of assembly of band angle bushing and disassembling fixture, the front support seat including bracket, the bore portion for being used to support connecting rod
With the rear support for the bar portion for being used to support connecting rod, the rear support is equipped with multiple altogether, and the tooling further includes for will serve as a contrast
Hydraulic press in the hole of set indentation connecting rod；
The bracket is placed on the workbench of hydraulic press, and the connecting rod is fixed by front support seat and rear support respectively
Afterwards, the bushing is pressed into the hole of connecting rod by hydraulic press, and bushing is extruded from tie rod holes.
There are two the rear support is set altogether.
The tooling further includes for positioning bushing and to the positioning sleeve of bushing conducting pressure, which is set to the hole of connecting rod
In.
The tooling further includes movable lifting apparatus and spring guiding device, and the activity lifting apparatus is set to front support seat
Place, the spring guiding device are set to below movable lifting apparatus, in being total to for the movable lifting apparatus and spring guiding device
Guarantee that bushing smoothly be pressed into and bushing is lifted not falling out and broken always when dismantling under same-action.
The spring guiding device is made of more springs.
The front support seat is equipped with one altogether.
Compared with prior art, the utility model has the following beneficial effects:
1) it improves precision: carrying out accurate positioning tool with this tooling, installation essence is improved for angled assembly
Spend and have consistency, uncertainty when avoiding manually installed.
2) save manpower: due to there is tooling to guarantee setting angle, worker's assembly is rapidly and accurate, improves assembly effect
In addition rate detects the reinspection for only needing to examine initial workpiece and fixed cycle, greatly saves human cost.
3) it uses the front support seat of support link hole portion and rear support that two are used to support bar portion, can contract
The volume of small tooling.

Specific embodiment
The utility model is described in detail in the following with reference to the drawings and specific embodiments.The present embodiment is with the utility model
Implemented premised on technical solution, the detailed implementation method and specific operation process are given, but the guarantor of the utility model
Shield range is not limited to the following embodiments.
A kind of assembly of band angle bushing and disassembling fixture, wherein the structure of bushing and connecting rod is as depicted in figs. 1 and 2, lining
Set 5 is the bushing with 2.5 degree of angles, as seen in figures 3-5, before tooling includes bracket 1, is used to support the bore portion of connecting rod 3
The rear support 4 of support base 2 and the bar portion for being used to support connecting rod 3, front support seat 2 are equipped with one, and rear support 4 is equipped with more altogether
A, tooling further includes the hydraulic press for being pressed into bushing 5 in the hole of connecting rod 3；
Bracket 1 is placed on the workbench of hydraulic press, after connecting rod 3 is fixed by front support seat 2 and rear support 4 respectively,
In hole of the bushing 5 by hydraulic press indentation connecting rod 3.
Rear support 4 is preferably uniformly distributed there are two setting altogether, and the stability of support can be improved in this way.
Tooling further includes for positioning bushing and to the positioning sleeve of bushing conducting pressure 6, which is set to the hole of connecting rod 3
In.
Tooling further includes movable lifting apparatus 8 and spring guiding device 7, and movable lifting apparatus 8 is set at front support seat 2,
