Description

Automatic locking mechanism for shaft head

Technical Field

The utility model relates to the technical field of precision equipment, in particular to an automatic locking mechanism for a shaft head.

Background

The assembly of the shaft head of the precision equipment is a great difficulty in engineering, such as the assembly of the shaft head of a servo motor. The servo motor belongs to precision equipment, and the shaft head is very inconvenient to install a coupler. The tolerance fit of the stub shafts should be an excessive fit of H6/H7, which requires the use of a hammer sledge or the like to assist in installation. The use of a hammer large hammer can cause damage to the servo motor. Generally, at this time, we will use the traditional method of enlarging the shaft hole size to increase the tolerance h6/E7 of the shaft hole. Thus, although the problem of installation is solved, the increased tolerance can cause the increased coaxiality tolerance of the coupler, and the operation of follow-up precision equipment such as a servo motor is affected to a certain extent.

Disclosure of Invention

The utility model provides an automatic locking mechanism for a shaft head, which aims to effectively solve the problems in the background technology.

The specific technical scheme is as follows:

the automatic locking mechanism for the shaft head comprises an outer sleeve, an inner sleeve, an outer sleeve through hole, an inner sleeve screw hole, an inner sleeve through hole, an outer sleeve screw hole and a bolt, wherein the outer circle of the outer sleeve and the outer circle of the inner sleeve are conical, the conical degree is 1:10, the outer sleeve is sleeved outside the inner sleeve, the left side of the outer sleeve is the through hole, the right side of the outer sleeve is the screw hole, the left side of the inner sleeve is the screw hole, the right side of the inner sleeve is the through hole, and the outer sleeve is connected with the inner sleeve through the bolt.

Preferably, a width adjusting groove of 2mm is arranged in the vertical direction of the end face of the inner sleeve.

Compared with the prior art, the utility model has the beneficial effects that: the device does not influence the coaxiality tolerance of the coupler, and is convenient for the shaft head connection of precision equipment.

Drawings

Fig. 1 is a schematic structural view of the present utility model.

Detailed Description

Spatially relative terms, such as "above … …," "above … …," "upper surface at … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial location relative to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "above" or "over" other devices or structures would then be oriented "below" or "beneath" the other devices or structures. Thus, the exemplary term "above … …" may include both orientations of "above … …" and "below … …". The device may also be oriented 90 degrees or at other orientations and the spatially relative descriptors used herein interpreted accordingly.

The following detailed description of the utility model refers to the accompanying drawings and preferred embodiments. As shown in fig. 1, the novel automatic locking mechanism for the shaft head comprises an outer sleeve 1, an inner sleeve 2, an outer sleeve through hole 3, an inner sleeve screw hole 4, an inner sleeve adjusting groove 5, an inner sleeve through hole 6, an outer sleeve screw hole 7 and a bolt 8, wherein the outer sleeve inner hole and the inner sleeve outer circle are in a conical shape, and the conical degree is 1:10. An adjusting groove with the width of 2mm is cut in the vertical direction of the end face of the inner sleeve. The left side of the outer sleeve is provided with a through hole, and the right side of the outer sleeve is provided with a screw hole. The left side of the inner sleeve is a screw hole, and the right side is a through hole. The outer sleeve is connected with the inner sleeve by bolts.

The specific embodiment of the automatic locking mechanism of the shaft head is as follows,

the bolt is inserted into the hole on the left side in the drawing and screwed downwards, when the bolt is screwed to the bottom of the through hole of the outer sleeve, the inner sleeve moves upwards along the taper hole, at the moment, the inner sleeve adjusting groove is contracted, the inner sleeve hole is reduced, and the locking is completed.

And loosening, namely inserting the bolt into a hole on the right side in the drawing, screwing downwards, and moving the outer sleeve upwards along the taper hole when the bolt is screwed to the bottom of the inner sleeve through hole, wherein the inner sleeve adjusting groove expands, the inner sleeve hole becomes large, and loosening is completed.

The foregoing is merely a preferred embodiment of the present utility model and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present utility model, which are intended to be comprehended within the scope of the present utility model.
