Description
Technical field
A kind of spring assembling/disassembling tool is the utility model is related to, more particularly to a kind of heavy vehicle brake shoe return spring dismounting
Instrument.
Background technology
At present, heavy-duty car uses drum brake more, and the elastic force of its brake shoe return spring is larger, gapping of spring compared with
It is small, disassembling operations insufficient space, more difficulty is dismantled also to it using instruments such as traditional crowbars, work efficiency is influenceed and has larger
Potential safety hazard.Based on this, special purpose device need to be made and solved the above problems.
China 201220145475.6 has opened a kind of heavy vehicle brake shoe return spring attaching/detaching apparatus, although can be to bullet
Spring is stretched, but its use is more troublesome for the return spring of disassembling operations insufficient space, it is especially desirable to by the device
Two jaws are inserted in spring simultaneously, and retainer spring gap is too small, and jaw is difficult in insertion spring.
The content of the invention
The purpose of this utility model is that for above-mentioned the deficiencies in the prior art, there is provided a kind of heavy vehicle brake shoe returns
Position spring assembling/disassembling tool, is solved because the elastic force of heavy vehicle brake hoof return spring is larger, gapping of spring is smaller, tears open
Difficult problem is dismantled caused by the reasons such as dress operating space deficiency.
The purpose of this utility model is achieved through the following technical solutions：
A kind of heavy vehicle brake shoe return spring dismantling device, by chain 1, boosting pipe 6, connecting bolt 8 and distance rod
10 are formed；The top of boosting pipe 6 is provided with U-type groove 4, and middle part is provided with through hole 5, and it is convex to be provided with the cylindrical type stretched out to the right at nearly bottom
Platform 7, the internal perisporium of boss 7 are provided with internal thread；The chain 1 passes through the through hole 5 of boosting pipe 6, and its one end is with hook 2, the other end
With pin 3；The distance rod 10 is connected by connecting bolt 8 with boss 7；Described one end of distance rod 10 is cuboid, another
Hold as hollow cylinder 9, and end of the cuboid away from hollow cylinder 9 carries open slot 11.
Described one end of connecting bolt 8 is threadedly coupled with boss 7, and the other end is connected with hollow cylinder 9.
Compared with prior art, the beneficial effects of the utility model are：
The utility model heavy vehicle brake shoe return spring dismantling device is simple in construction, and it is easy to make, and is braked in dismounting
It is easy to use during shoe plate return spring, fast, safely, it is possible to increase operating efficiency, reduce labor intensity, while improve and tear open
The security of dress process.It makes full use of lever principle easily to dismount return spring, and can be to most of heavy vehicles
Brake shoe return spring dismounts, especially the dismounting to liberating brand heavy vehicle brake shoe return spring.

Embodiment
Describe specific embodiment of the present utility model in detail below in conjunction with the accompanying drawings.
As shown in figure 1, heavy vehicle brake shoe return spring dismantling device is by chain 1, boosting pipe 6, connecting bolt 8 and pushes away
Power bar 10 is formed, and the structure of connecting bolt 8 is as shown in Figure 2.
The top of the boosting pipe 6 is provided with U-type groove 4, and middle part is provided with through hole 5, the cylinder stretched out to the right is provided with nearly bottom
Type boss 7, and the internal perisporium of boss 7 is provided with internal thread.The chain 1 passes through through hole 5, and its one end is with hook 2, other end band
There is pin 3, the length of chain 1 can be adjusted by pin 3.Described one end of distance rod 10 is cuboid, and the other end is open circles
Cylinder 9, and end of the cuboid away from hollow cylinder 9 carries open slot 11.Distance rod 10 passes through connecting bolt 8 and boss 7
Connection, it is specially：Described one end of connecting bolt 8 is threadedly coupled with boss 7, and the other end is connected with hollow cylinder 9.With pulling
Hand turns connecting bolt 8, and connecting bolt 8 be able to can also be stretched from the precession of 6 bottom boss of boosting pipe 7 or back-out, corresponding distance rod 10
Go out or shrink.
As shown in figure 3, during installation：If return spring is arranged in the supporting pin of bottom plate, first spring one end shackle is pacified
In a supporting pin, spring other end shackle is enclosed on boosting pipe 6, and U-type groove 4 is enclosed in another supporting pin of bottom plate,
The lower end of boosting pipe 6 is pressed downward, spring shackle is just slid downwardly into supporting pin.
As shown in figure 4, if return spring is arranged in bottom plate circular hole, spring one end shackle is first arranged on a circular hole
In, the other end shackle of spring is hung on open slot 11, and boosting pipe 6, which is put into correct position, makes its lower end have fulcrum, uses spanner
Turn connecting bolt 8, distance rod 10 can push the spring open, when mounting hole of the spring shackle on bottom plate, with hand adjustment section
Distance rod 10, spring shackle is linked into bottom plate hole, then connecting bolt 8 is turned with spanner, distance rod 10 is withdrawn, installation.
As shown in figure 5, for elastic smaller and installation site outside, the broad spring in operating space can be first spring
Shackle one end is installed, and the other end is hung on hook circle hook 2, and pin 3 is inserted into the correct position of chain 1, is stretched using lever principle
Spring installs another shackle of spring.Other end shackle can also be put into U-type groove 4, with hand propelled boosting pipe 6, make bullet
Spring shackle is installed.
During dismounting：Spring in supporting pin, open slot 11 are inserted in the gap between shackle and supporting pin, with pulling
Hand turns connecting bolt 8, and the meeting push the spring of distance rod 10 is opened, and spring dismounting is completed.Other situations refer to time step installed above
Suddenly, it is easy to dismantle spring.
The elastic force of heavy vehicle brake hoof return spring is larger, and gapping of spring is smaller, disassembling operations insufficient space,
It is more difficult with tool ejectors such as traditional crowbars, influence work efficiency and have larger potential safety hazard.The utility model heavy goods vehicles
Brake shoe return spring dismantling device is simple in construction, and it is easy to make, the side of using when dismounting brake shoes return spring
Just, fast, safely, it is possible to increase operating efficiency, reduce labor intensity, while improve the security of disassembly process.Make full use of
Lever principle can easily dismount return spring.Most of heavy vehicle brake shoe return springs can be dismounted, especially to solution
Put the dismounting of brand heavy vehicle brake shoe return spring.
