SUMMERY OF THE UTILITY MODEL
To the problem, the utility model provides a quick extracting tool of blind hole bearing conveniently dismantles blind hole bearing.
The utility model discloses take following technical scheme to realize above-mentioned purpose:
a blind hole bearing rapid dismounting tool is applied to a blind hole bearing and comprises an ejector rod, a screw rod and a threaded sleeve, wherein the ejector rod is connected with the screw rod, the free tail end of the ejector rod penetrates through the threaded sleeve, and the screw rod is in threaded connection with the threaded sleeve; the threaded sleeve is kept away from the one end of screw rod is equipped with and holds the chamber, it is located to hold the chamber the relative both sides of ejector pin are the activity respectively and are equipped with round pin slider, round pin slider is kept away from one side of screw rod is equipped with the guide way, the threaded sleeve is close to the tip of round pin slider is equipped with guide screw, guide screw is in the sliding motion in the guide way.
Preferably, the blind hole bearing is arranged on the box body, the box body is provided with a blind hole, and the blind hole bearing is arranged in the blind hole.
Preferably, the diameter of the free end of the ejector rod is gradually reduced.
Preferably, the drift diameter of one end of the round pin sliding block, which is far away from the ejector rod, is gradually reduced.
The utility model has the advantages that:
the utility model discloses a quick extracting tool of blind hole bearing, according to the characteristic of bearing blind hole, the extracting tool of scalable slider is designed out, round pin slider is withdrawed and is held the chamber after, extracting tool just can stretch into the bearing blind hole, then the conical surface through the ejector pin is ejecting target in place to the round pin slider, make the round pin slider block the blind hole bearing, the rethread screw rod drives the ejector pin and withstands bearing blind hole bottom down toward interior, round pin slider counter-force is toward ejecting out blind hole bearing outward, it is very quick convenient to dismantle, can apply the dismantlement occasion of a lot of blind hole bearings, therefore, the clothes hanger is strong in practicability.

Fig. 1 is the embodiment of the utility model provides a blind hole bearing quick extracting tool's structure schematic diagram.
In the attached drawing, 1-blind hole bearing, 2-ejector rod, 3-screw rod, 4-thread bush, 5-round pin slide block, 6-guide groove, 7-guide screw and 8-box body.
Detailed Description
The present invention will be described in detail with reference to fig. 1 and the following detailed description.
Referring to fig. 1, the present embodiment provides a blind bearing quick-detaching tool, which is applied to a blind bearing 1. The quick extracting tool of blind hole bearing of this embodiment includes ejector pin 2, screw rod 3 and thread bush 4. The ejector rod 2 is connected with the screw rod 3, the left end of the ejector rod 2 penetrates through the threaded sleeve 4, and the screw rod 3 is in threaded connection with the threaded sleeve 4. The one end that screw rod 3 was kept away from to thread bush 4 is equipped with and holds the chamber, holds the chamber and lies in the relative both sides of ejector pin 2 activity respectively and is equipped with round pin slider 5, and one side that screw rod 3 was kept away from to round pin slider 5 is equipped with guide way 6, and the tip that thread bush 4 is close to round pin slider 5 is equipped with guide screw 7, and guide screw 7 is the sliding motion in guide way 6.
In the present embodiment, the blind hole bearing 1 is provided on the case 8, the case 8 is provided with a blind hole, and the blind hole bearing 1 is mounted in the blind hole.
The utility model discloses a quick extracting tool of blind hole bearing is when using, revolves soon screw rod 3 toward outer, and screw rod 3 drives ejector pin 2 and moves toward outer, can retrieve in thread bush 4 up to round pin slider 5. At this time, the guide groove 6 and the guide screw 7 cooperate to ensure that the round pin slider 5 does not slip. After the round pin slider 5 withdraws and holds the chamber, put into the blind hole of blind hole bearing 1 with the left end of thread bush 4 in, until 4 terminal surfaces of thread bush are at the bottom of the blind hole on box 1, then inwards twist screw rod 3, screw rod 3 drives ejector pin 2 and pushes up inwards always, when the left end of ejector pin 2 passes through round pin slider 5, the round pin slider 5 of both sides all outwards opens, continue inwards twist screw rod 3 and drive ejector pin 2 and push up to the blind hole bottom, open round pin slider 5 in this process is outwards ejecting blind hole bearing 1 gradually.
In the embodiment, the drift diameter of the left end of the ejector rod 2 is gradually reduced, so that the ejector rod 2 can conveniently push the round pin sliding block 5 to be outwards opened in the inward screwing process.
In this embodiment, the drift diameter of the end of the round pin slider 5 far away from the top rod 2 is gradually reduced, so that the round pin slider 5 can slowly pry the blind hole bearing 1, and the blind hole bearing 1 can be gradually ejected outwards.
Although the invention has been described in detail and with reference to specific embodiments thereof, it will be apparent to one skilled in the art that modifications and improvements can be made thereto. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
