Abstract
The utility model discloses a kind of slide rail type bolt tightening and take out frock, comprise swivel nut, the erection support coordinating with swivel nut, power transmission shaft and the transmission nut coordinating with power transmission shaft; Described swivel nut is positioned at erection support and adopts slide rail type to be connected with erection support, on erection support, offers chute, is processed with the slide block being used in conjunction with chute on swivel nut, coordinates swivel nut in erection support, to slide through slide block with chute; Described power transmission shaft and swivel nut are integrated casting, and power transmission shaft passes erection support between swivel nut and erection support.The utility model slides forward or backward swivel nut by rotating transmission nut on erection support, thereby tightens or take out bolt, and while having avoided tighting a bolt like this, nut can spin and in the situation that transmitting torque is limited, the problem of inconvenient operation.
Description
Technical field
The utility model relates to machine tools field, is specifically related to a kind of slide rail type bolt tightening and takes out frock.
Background technology
Studs is all threaded column securing members of tool of a kind of axial two ends, being mainly used in main body is main equipment installation accessories, such as visor, mechanical sealing base, deceleration frame etc., at this moment just use studs, one end is screwed into main body, installs other end band nut after annex, because annex is often dismounting, while directly adopting bolt-connection main body and annex, main body thread can wear and tear or damage in the course of time, can be very convenient and use stud to change.
In process of production, often use studs, but tightening and taking out of studs is a larger difficult problem, particularly to studs, required moment of torsion to be screwed in screw and in screw and taken out.Double end stud screwing in the past and take out and often to adopt two schemes: 1. with two nuts after one end of stud is carried on the back tightly mutually, with hexagon, by nut, tighten and take out again studs, the problem of this scheme maximum be stubborn power too big nut can spin.2. with a nut, be screwed in one end of double-screw bolt, the little stay bolt in river is pressed on an end cap with internal square hole between double-screw bolt termination and nut again, with protruding four directions, pulling off rotation stud, also there is complex structure, operation shortcoming not too easily in this scheme, and the moment of torsion simultaneously transmitting is also limited.
Utility model content
For above-mentioned prior art, the utility model will solve: existing bolt is screwed into that taking-up instrument nut when tighting a bolt can spin and also technical problem not too easily of operation in the situation that transmitting torque is limited.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
Slide rail type bolt tightening takes out a frock, it is characterized in that, comprises swivel nut, the erection support coordinating with swivel nut, power transmission shaft and the transmission nut coordinating with power transmission shaft; Described swivel nut is positioned at erection support and adopts slide rail type to be connected with erection support, on erection support, offers chute, is processed with the slide block being used in conjunction with chute on swivel nut, coordinates swivel nut in erection support, to slide through slide block with chute; Described power transmission shaft and swivel nut are integrated casting, and power transmission shaft passes erection support between swivel nut and erection support.
In the utility model, described erection support and swivel nut form by iron casting.
Operation principle of the present utility model is:
Need the bolt of installing or taking out after swivel nut is threaded, rotate transmission nut 4 swivel nuts and slide forward or backward on erection support, and then tighten or take out bolt.
Compared with prior art, the utlity model has following beneficial effect:
One, the utility model slides forward or backward swivel nut by rotating transmission nut on erection support, thereby tightens or take out bolt, and while having avoided tighting a bolt like this, nut can spin and in the situation that transmitting torque is limited, the problem of inconvenient operation;
Two, the utility model is simple in structure, with low cost, easy to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Reference numeral is: 1 is that swivel nut, 3 is that erection support, 4 is transmission nut for waiing upon the bolt, 2 that takes out or tighten.
The specific embodiment
Below in conjunction with the drawings and the specific embodiments, the utility model will be further described.
Slide rail type bolt tightening takes out a frock, comprises swivel nut, the erection support coordinating with swivel nut, power transmission shaft and the transmission nut coordinating with power transmission shaft; Described swivel nut is positioned at erection support and adopts slide rail type to be connected with erection support, on erection support, offers chute, is processed with the slide block being used in conjunction with chute on swivel nut, coordinates swivel nut in erection support, to slide through slide block with chute; Described power transmission shaft and swivel nut are integrated casting, and power transmission shaft passes erection support between swivel nut and erection support.Described erection support and swivel nut form by iron casting.The utility model slides forward or backward swivel nut by rotating transmission nut on erection support, thereby tightens or take out bolt, and while having avoided tighting a bolt like this, nut can spin and in the situation that transmitting torque is limited, the problem of inconvenient operation.
