Description

Tool for reworking needle roller bearing of steering machine

Technical Field

The utility model relates to a steering gear spare part installation technical field, specific saying is a steering gear needle bearing instrument of doing over again.

Background

In the installation of the needle bearing in the automobile steering gear, the needle bearing is usually pressed to a specified position by using an electro-hydraulic cylinder, and then the generated force is monitored to judge whether the press-fitting process meets the requirement, and because the needle bearing is not pressed to the bottom, the situation that the press-fitting is not qualified is easy to occur.

And because of the special structure of the shell and the needle bearing pressure head, the bearing pressed into the shell cannot be removed under the condition of not influencing the quality, so that the whole steering gear is scrapped due to the unqualified press fitting of a small part, and the scrapping cost is increased.

Therefore, it is necessary to design a reworking tool which can remove the press-fitted and dislocated needle roller bearing without damaging a steering gear.

Disclosure of Invention

The utility model discloses broken through the difficult problem of prior art, designed one kind and can not destroy the instrument of doing over again that demolishs the bearing of pressure equipment dislocation under the condition of steering engine.

In order to achieve the above object, the utility model discloses a turn to quick-witted bearing instrument of doing over again, include: locating lever, petiole, frame, uide bushing, tight frock of clamp, spacing bolt, screw up the bolt, its characterized in that: a guide sleeve is embedded in the outer frame and is in a T shape, the head of the guide sleeve is erected above the outer frame, the vertical part of the guide sleeve is embedded in the outer frame, a small handle is embedded and fixed at the head of the guide sleeve, a clamping tool is sleeved at the outer edge of the vertical part of the guide sleeve, the upper half part of the clamping tool is positioned between the guide sleeve and the outer frame, the lower half part of the clamping tool extends out of the outer frame, a positioning rod is inserted downwards from the upper part of the head of the guide sleeve and sequentially penetrates through the guide sleeve and the clamping tool, a supporting table extending outwards is arranged at the bottom end of the positioning rod, the upper surface of the supporting table is contacted with the bottom end of the clamping tool, a long groove is formed at the lower half part of the positioning rod, a strip-shaped hole is formed at the position, corresponding to the long groove, a limiting bolt penetrates through the strip-, the tightening bolt is sleeved on the outer edge of the positioning rod.

An O-shaped ring is clamped between the clamping tool and the outer frame.

The number of the clamping tools is 2, and the clamping tools are semicircular arc-shaped plates.

Compared with the prior art, the utility model, the compatibility is strong, satisfies different products and disassembles the requirement, and is little and light, does not need very big reworking region, and convenient to use need not special instrument of reworking, can not harm the steering gear casing.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a cross-sectional view of the present invention.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

Referring to fig. 1~2, the utility model discloses a turn to quick-witted bearing instrument of doing over again, include: the positioning device comprises a positioning rod, a small handle, an outer frame, a guide sleeve, a clamping tool, a limiting and limiting bolt and a tightening bolt, wherein the guide sleeve 2 is embedded in the outer frame 1, the guide sleeve 2 is T-shaped, the head of the guide sleeve 2 is erected above the outer frame 1, the vertical part of the guide sleeve 2 is embedded in the outer frame 1, the small handle 3 is embedded and fixed at the head of the guide sleeve 2, the clamping tool 4 is sleeved at the outer edge of the vertical part of the guide sleeve 2, the upper half part of the clamping tool 4 is positioned between the guide sleeve 2 and the outer frame 1, the lower half part of the clamping tool 4 extends out of the outer frame 1, the positioning rod 5 is inserted downwards from the upper part of the head of the guide sleeve 2 and sequentially penetrates through the guide sleeve 2 and the clamping tool 4, the bottom end of the positioning rod 5 is provided with an outwards extending receiving platform 6, the upper surface of the receiving platform 6 is, a strip-shaped hole 10 is formed in the outer frame at a position corresponding to the elongated slot 7, a limiting bolt 8 penetrates through the strip-shaped hole 10 and is fixedly inserted into the elongated slot 7, a tightening bolt 9 is arranged above the head of the guide sleeve 2, and the tightening bolt 9 is sleeved on the outer edge of the positioning rod 5.

The utility model discloses it is equipped with O type circle to press from both sides between tight frock 4 of well clamp and the frame 1, plays sealed effect.

The utility model discloses well number of pressing from both sides tight frock 4 is 2, and its shape is semi-circular arcuation board, and two semi-circular arcuation boards form a circular shape clamping jaw together for clip bearing.

In the concrete implementation, the steering machine is placed on the work returning table, the outer frame is held by the hand, the small handle is held by the other hand, the guide sleeve is pulled out from the position of the clamping tool, and the clamping tool is not limited, so that the steering machine can move in a small range in the left-right direction. At the moment, the tool is placed above the steering machine, the tool cannot lean against the bottom end of the shell to be clamped, the small handle is rotated, the positioning rod is inserted into the positioning hole of the outer frame, and relative movement between the guide sleeve and the outer frame is guaranteed not to occur. At the moment, the spanner is used for screwing the screwing bolt, so that the guide sleeve slowly enters the inner hole of the outer frame, the tool at the lower end of the guide sleeve can also fix 2 semicircular arc-shaped plates of the clamping tool and stretch the two semicircular arc-shaped plates, the needle roller bearing in the steering machine can be fixed by the clamping tool, the clamping tool can slowly rise along with the thread as long as the bolt is continuously screwed, until the needle roller bearing is completely pulled out, the screwing bolt is loosened, and the needle roller bearing is taken down.

Wherein, the uide bushing passes through the small handle and connects the locating lever, and the effect of spacing bolt prevents that the locating lever from being taken out from the frame completely, plays spacing effect.

For convenient work, can also be in the utility model discloses go up to increase big handle 11 to fix whole outside sleeve, the operation of being more convenient for.
