Description

Self-adjusting sleeve butt

Technical Field

The utility model relates to a sleeve mechanism of taking a head technical field especially relates to self-interacting sleeve takes a head.

Background

The common problem of the horizontal tightening equipment is that the sleeve is lapped and the cap is not easy to identify due to the self weight of the sleeve and the clearance of the connecting pin, and the traditional solution is to use the sleeve which is as short as possible by righting the sleeve by the sleeve extension rod, so that the manufacturing process is complex and the manufacturing cost is high.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem that the horizontal screwing equipment is inconvenient or easy to cause cap not-recognition or cap dislocation in the using process.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the self-adjusting sleeve joint comprises a sleeve, a transfer shaft and a tightening shaft, wherein one end of the transfer shaft is sleeved in the tightening shaft, the other end of the transfer shaft is sleeved in the sleeve, a gap is formed between the sleeve and the tightening shaft, a spring sleeved outside the transfer shaft is arranged on the gap, one end of the spring is in contact with the end face of the transfer shaft, and the other end of the spring is in contact with the end face of the tightening shaft.

Preferably, the adapter shaft is provided with an inner hole, and the sleeve sleeved outside the adapter shaft is provided with a through hole corresponding to the adapter shaft.

Preferably, a gasket is arranged between one end of the spring and the end surface of the tightening shaft.

The utility model discloses an increase a small amount of parts fast, accurate, conveniently realized screwing up a drive division. The tightening failure rate of the equipment generated in the tightening process can be solved in the simplest method. The utility model discloses can reduce the sleeve and rock phenomenons such as, prevent effectively that the cap is not known to the sleeve joint, this device simple structure is easy, convenient operation, adaptability is strong.

Reference numbers in the figures:

1. a sleeve; 2. a spring; 3. a gasket; 4. screwing a shaft; 5. and (4) transferring the shaft.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

As shown in fig. 1, the self-adjusting sleeve joint provided by the present invention comprises a sleeve 1, a transfer shaft 5 and a tightening shaft 4, wherein one end of the transfer shaft 5 is sleeved in the tightening shaft 4, the other end of the transfer shaft 5 is sleeved in the sleeve 1, the transfer shaft 5 sleeved in the sleeve 1 is provided with an inner hole, and the sleeve 1 sleeved outside the transfer shaft 5 is provided with a through hole corresponding to the transfer shaft 5; the perpendicularity between the end surface of the sleeve 1 and the through hole on the sleeve 1 and the inner hole of the adapter shaft 5 is utilized, the bolt penetrates through the through hole to enter the inner hole, and the sleeve 1 is pressed tightly by means of the expansion force of the spring 2 to ensure the coaxiality of the sleeve 1 and the tightening shaft 4 so as to avoid the sleeve lap phenomenon;

a gap is arranged between the sleeve 1 and the tightening shaft 4, a spring 2 sleeved outside the transfer shaft 5 is arranged on the gap, one end of the spring 2 is in contact with the end face of the sleeve 1, and the other end of the spring 2 is in contact with the end face of the tightening shaft 4.

Furthermore, a gasket 3 is arranged between one end of the spring 2 and the end surface of the sleeve 1, and the gasket 3 plays a role in protecting the tightening shaft from being abraded.

The working principle of the utility model is as follows:

when in tightening, the expansion force of the spring 2 is utilized to support the sleeve 1 and the tightening shaft 4 to overcome the weight of the sleeve 1 and the clearance between the connecting pieces; the perpendicularity between the end face of the sleeve 1 and the through hole in the sleeve 1 and the inner hole of the adapter shaft 5 is utilized, the bolt is inserted into the through hole and inserted into the inner hole after penetrating through the through hole, so that the coaxiality between the sleeve 1 and the adapter shaft 5 is ensured, the coaxiality between the sleeve 1 and the adapter shaft 4 is also ensured due to the fact that one end of the adapter shaft 5 is sleeved in the tightening shaft 4, the sleeve 1 is pressed by the expansion force of the spring 2, and the problem that the cap cannot be recognized by a sleeve lap or the cap is recognized and misplaced is solved.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and to simplify the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.
