Abstract

The utility model discloses a truck oil gas suspension round pin axle draws frock, including support sleeve, support apron, screw rod and nut, at the round pin axle head portion processing internal thread of being drawn, screw rod one end carries out threaded connection with the round pin axle, and the support sleeve cover is on the screw rod, and the support cover compresses tightly support sleeve's tip on the screw rod, the other end threaded connection of nut and screw rod. The utility model discloses utilize screw nut's strength, utilize the afterburning production of spanner to the drawing force of round pin axle, will sell the axle and draw from oil gas spring fixed position and take out, can provide the drawing force more than 2 tons, utilize pnematic or electronic trigger afterburning, will sell the axle and draw out step by step, can not produce the harm to the round pin axle. The utility model discloses an assembled structure draws the backing plate that the space used is different to the difference, and nimble combination when realizing using has improved the adaptability of frock.

Description

Truck oil-gas suspension pin shaft drawing tool

Technical Field

The utility model belongs to the technical field of the gas spring installation, concretely relates to frock is drawn to truck oil gas suspension round pin axle.

Background

When the truck with part matched oil-gas spring suspension is used for maintaining and replacing the oil-gas spring bearing, the pin shaft for fixing the oil-gas spring needs to be taken out. Because the space that the round pin axle was taken out limits, can't use the copper hammer to beat to take out.

A tool needs to be designed, and the pin shaft is taken out by using drawing force on the other side.

SUMMERY OF THE UTILITY MODEL

The utility model provides a frock is drawn to truck gas suspension round pin axle has solved the problem that can't change oil gas spring round pin axle.

In order to solve the technical problem, the utility model provides a frock is drawn to truck oil gas suspension round pin axle, its characterized in that: the internal thread is processed at the end part of the pulled pin shaft, one end of the screw shaft is in threaded connection with the pin shaft, the support sleeve is sleeved on the screw shaft, the support cover plate is sleeved on the screw shaft to tightly press the end part of the support sleeve, and the nut is in threaded connection with the other end of the screw shaft.

Has the advantages that: the utility model discloses utilize screw nut's strength, utilize the afterburning production of spanner to the die pull power of round pin axle, draw the round pin axle from gas spring fixed position and take out, concrete advantage as follows:

a. this special frock can provide the drawing force more than 2 tons, utilizes pnematic or electronic trigger afterburning, and the substep is drawn out the round pin axle, can not produce the harm to the round pin axle.

b. The utility model discloses an assembled structure draws the backing plate that the space used is different to the difference, and nimble combination when realizing using has improved the adaptability of frock.

a. The utility model discloses a frock adopts integrated configuration, makes to draw frock processing simple, and the frock material adopts the seamless steel pipe of 25mmQ345 steel sheet, 12mm thickness and M28's standard bolt nut, uses the cutting process preparation, shortens frock preparation cycle, has reduced the frock cost.

d. The bolt and the nut are adopted for screwing and drawing, the operation is simple and reliable, the operation can be carried out by one person, and the service difficulty of replacing the pin shaft is greatly reduced.

Detailed Description

In order to make the objects, contents and advantages of the present invention clearer, the following description will be made in further detail with respect to the embodiments of the present invention.

The utility model provides a truck oil gas suspension pin shaft drawing tool, which comprises a support sleeve 4, a support cover plate 1, a coarse thread screw rod 3, a coarse thread nut 2 and a backing plate 5, wherein a pin shaft 6 is fixed on a suspension control arm;

the internal thread is processed at the end part of the pin shaft to be drawn, one end of a screw rod 3 is in threaded connection with a pin shaft 6, a supporting sleeve 4 is sleeved on the screw rod 3, a supporting cover plate 1 is sleeved on the screw rod 3 and tightly attached to the screw rod 3, the end part of the supporting sleeve 4 is compressed, a nut 2 is manually installed at the other end of the screw rod 3, a pneumatic or electric trigger is utilized to apply force to the nut 2, and the screw rod 3 generates drawing force on the pin shaft 6. After the pin shaft moves along the direction of the drawing force, the screw 3 is too long and cannot apply force to the pneumatic or electric trigger, the nut 2 needs to be loosened, the backing plate 5 is plugged between the sleeve 4 and the workpiece, and then the nut 2 is tightened again for drawing. Repeating the steps for 3-4 times, and completely taking out the pin shaft.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.

Claims
