Description

Skin pit extraction tool

Technical Field

The utility model belongs to the white automobile body of passenger train field of making, concretely relates to covering pit pull-out ware.

Background

In the process of manufacturing the white body of the passenger car, the body framework of the passenger car is welded according to the design to form a car sound framework, and then skin is coated on the body framework. Local unevenness or sinking can occur in the expanding and pulling process of the skins on the two sides; local unevenness or depression can occur on the front and rear wall skins in the manufacturing process; the body-in-white is deformed by impact during the moving process, and local depressions are generated.

To the above-mentioned problem, the mode of solving at present is that the staff slowly repairs through knocking, but this kind of mode is difficult to master the strength, and is higher to staff's technical requirement, and the restoration inefficiency.

SUMMERY OF THE UTILITY MODEL

Based on the above, the utility model provides a covering pit pull-out ware can restore the local unevenness of covering or sunken fast, improves product preparation quality.

The utility model discloses a technical scheme be, a covering pit pull-out ware, the electric iron comprises a cylinder body, the fixed pull-out head that is equipped with of cylinder head end, tail end welding handle, cylinder middle part cover are established and are strikeed the cover, striking cover and cylinder sliding connection are equipped with the dog between striking cover and the handle, the dog is close to the cylinder tail end.

Furthermore, the central axes of the column body, the pulling head, the handle, the impact sleeve and the stop block are positioned on the same straight line.

Furthermore, the head end of the pulling head is conical, and the tail end of the pulling head is welded with the column body.

Furthermore, the impact sleeve comprises an impact inner sleeve and an impact outer sleeve, the impact outer sleeve is welded outside the impact inner sleeve, the impact outer sleeve is located in the middle of the impact inner sleeve, and two ends of the impact inner sleeve extend out of the impact outer sleeve.

Further, the cylinder is the cuboid structure that has certain length, and the striking cover is the quarter bend that matches with the cylinder, and strikes the cover and adopts steel preparation.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model has the advantages of being simple in structure and convenient in operation, the control striking power of being convenient for is said in the use, is fit for most of staff's operation, and effectively makes passenger train covering pit resume, improves repair efficiency and restoration quality.

Drawings

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a sectional view of the present invention;

the labels in the figure are: 1. the device comprises a main body, 2, a pulling head, 3, a handle, 4, an impact sleeve, 41, an impact inner sleeve, 42, an impact outer sleeve, 5 and a stop block.

Detailed Description

The present invention will be further explained with reference to the drawings attached to the specification so as to be better understood by those skilled in the art.

Example 1

As shown in fig. 1-2, the skin pit extractor comprises a cylinder 1, an extraction head 2, a handle 3, an impact sleeve 4 and a stop 5.

The column body 1 is of a cuboid structure with a certain length, a pulling head 2 is fixedly arranged at the head end of the column body 1, a handle 3 is welded at the tail end of the column body 1, and the stability and the balance of the pulling device are kept through the handle 3; the impact sleeve 4 is a rectangular tube matched with the column body 1, is sleeved in the middle of the column body 1 and is in sliding connection with the column body 1, a stop block 5 is arranged between the impact sleeve 4 and the handle 3, and the stop block 5 is close to the tail end of the column body 1; the central axes of the column body 1, the pulling head 2, the handle 3, the impact sleeve 4 and the stop block 5 are positioned on the same straight line, so that the force application direction is ensured to be horizontal, and the force is favorably mastered.

Further, the impact sleeve 4 comprises an impact inner sleeve 41 and an impact outer sleeve 42, the impact outer sleeve 42 is welded outside the impact inner sleeve 41, the impact outer sleeve 42 is located in the middle of the impact inner sleeve 41, two ends of the impact inner sleeve 41 extend out of the impact outer sleeve 42, and the impact sleeve 4 is made of steel. The design of the striking sleeve 4 is beneficial to the centralized sliding of the gravity center of the striking sleeve to strike the stop block 5 and endow the extractor with outward force.

The using method comprises the following steps: spot welding the front part of the puller head 2 and the skin sunken part, holding the handle 3 by one hand, and pulling backwards slightly, and keeping the puller horizontal and stable; according to the size of the depression of the skin, the other hand holds the impact 4 sleeve, slides to the stop block from one end close to the pulling head 2, impacts the stop block 5, and exerts force from small to large until the pits are repaired.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention, therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
