Description
Technical Field
The utility model relates to a maintenance of equipment in aviation field, concretely relates to axle seal extraction tool.
Background
The shaft seal extraction tool is auxiliary equipment used for taking out the shaft seal from the inside of a shaft cavity, and the traditional shaft seal extraction method is that calipers are used, the two ends of the calipers are clamped inside clamping grooves, and then the shaft seal is pulled out. In this method, the shaft seal and the shaft cavity are in interference fit, the clamping is very tight, and the shaft seal is difficult to lift by using the original tool. Meanwhile, the matching surface between the original tool and the shaft seal clamping groove is very small, and the shaft seal is easily damaged.
In order to solve the above problems, we have made a series of improvements.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a shaft seal draws instrument to overcome the above-mentioned shortcoming and not enough that prior art exists.
A shaft seal extraction tool, comprising: the chuck, a positioning block, a guide sleeve, a collision rod, a collision block and a shaft seal clamping piece, wherein the number of the chuck is 2, the chuck is a hollow semi-ring, one end of the chuck is provided with external threads, the other end of the chuck is connected with the shaft seal clamping piece, the positioning block is connected in the hollow semi-rings of the two chucks, the guide sleeve is provided with internal threads, the external threads of the chuck are in threaded connection with the internal threads of the guide sleeve, a collision cavity is arranged in the middle of the collision block, the external threads are arranged at one end of the collision rod, a tail protruding block is arranged at the other end of the collision rod, the collision block is sleeved on the collision rod in a sliding connection mode through the collision cavity, the diameter of the tail protruding block is larger than.
Furthermore, the outer side of the guide sleeve is carved with reticulate patterns.
Further, the outer side of the collision block is provided with a radian.
The utility model has the advantages that:
compared with the prior art, the utility model adopts a brand new design, the chuck of the extracting tool can perfectly fit the clamping groove of the shaft seal, and the shaft seal can not be damaged; the outer side of the chuck is provided with a guide sleeve and is connected with the collision rods, the collision blocks on the collision rods are moved quickly, and the shaft seal can be pulled out easily by using the impact force between the collision blocks.

Detailed Description
The present invention will be further described with reference to the following examples. It should be understood that the following examples are illustrative only and are not intended to limit the scope of the present invention.
Example 1
Fig. 1 is a schematic structural diagram of the present invention.
As shown in fig. 1, a shaft seal extraction tool includes: the chuck 100, the locating block 200, the guide sleeve 300, the lance 400, the lance 500 and the shaft seal card 600, the number of the chuck 100 is 2, the chuck 100 is a hollow semi-ring, one end of the chuck 100 is provided with an external thread, the other end of the chuck 100 is connected with the shaft seal card 600, the locating block 200 is connected in the hollow semi-rings of the two chucks 100, the guide sleeve 300 is provided with an internal thread, the external thread of the chuck 100 is in threaded connection with the internal thread of the guide sleeve 300, the middle of the lance 500 is provided with a striking cavity 510, one end of the lance 400 is provided with an external thread, the other end of the lance 400 is provided with a tail lug 410, the lance 500 is sleeved on the lance 400 through the striking cavity 510 and is in sliding connection, the diameter of the tail lug 410 is larger than.
The outer side of the guide sleeve 300 is engraved with a reticulate pattern.
The outside of the bump 500 is provided with a radian.
The utility model discloses compare with traditional instrument of drawing, adopt brand-new project organization, the utility model discloses a chuck 100 removes the draw-in groove of laminating bearing seal, can not cause the damage to the bearing seal. The guide sleeve 300 is assembled outside the chuck 100 and connected to the striking rod 400, and the shaft seal can be easily pulled out by the impact force of the striking block 500 by rapidly moving the striking block 500 on the striking rod 400.
The utility model discloses an application method does, goes into the draw-in groove of bearing seal with two chucks 100 cards, installs locating piece 200 inside two chucks 100, fixed chuck. The guide bush 300 is screwed to the external thread of the chuck 100, and the plunger 400 is screwed to the guide bush 300. The collision block 500 is slid rapidly to pull the shaft seal out of the shaft cavity by impact force. The diameter of the tail bump 410 is larger than that of the bumping cavity 510, so that the bumping cavity 510 can be clamped by the tail bump 410 during the pulling process and cannot fly out.
The above description has been made of the embodiments of the present invention, but the present invention is not limited thereto, and various changes may be made without departing from the spirit of the present invention.
