Description

Rotatory frock of wire winding class product

Technical Field

The utility model belongs to the technical field of space product precision finishing, concretely relates to rotatory frock of wire winding class product.

Background

At present, a sensor stator, a motor stator and the like in the development and production of a new generation of inertial navigation device are winding products, the products are rotary parts, and the problems of winding, breaking, damage and the like of winding are easily caused by turning an excircle with a wire in the machining process. Therefore, during part processing, the winding needs to be fixed, and the winding is wound on a mandrel and bonded by using a white tape to be fixed on the mandrel in a commonly used method. However, the method has the defects of low efficiency and unreliable fixation, and easily causes the snapping, breaking and abrasion of the wire in the winding and bonding processes.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the above-mentioned problem, a rotatory frock of wire winding class product is provided, has overcome the wire winding and twine easily in the course of working, has broken, impaired problem.

The utility model provides a rotatory frock of wire winding class product, including sleeve pipe, tube head and two bearings, sleeve pipe one end is provided with the step hole, the bearing inner race with the cover tube wall transition fit, distribute and be in the sleeve pipe both ends, one with sleeve pipe one end parallel and level, another with step hole parallel and level, tube head main-end excircle with step hole transition fit. Further, the tube head is of a step shaft structure, and a blind hole is formed in the large end of the tube head.

The utility model has the advantages and effects: compared with the prior art, the utility model has the beneficial effects of through using this frock in wire winding class product course of working for reduced wire winding, adhesive tape bonding, the adhesive tape tear cloth time in the course of working, improved the reliability of wire winding protection simultaneously, greatly reduced the impaired probability of wire winding, further improved machining efficiency and processingquality.

Detailed Description

Embodiments of the present invention are further described below with reference to the accompanying drawings.

As shown in figure 1, the utility model discloses rotatory frock comprises sleeve pipe 1, tube head 2, two bearings 3 triplexes. The outer circles of the two bearings 3 are in transition fit with the inner wall of the sleeve 1, and are distributed at two ends of the sleeve 1, one of the two bearings is parallel and level with one end of the sleeve 1, the other bearing is parallel and level with the step hole 4 in the sleeve 1, and the outer circle of the large end of the tube head 2 is in transition fit with the step hole 4 in the sleeve 1. When the pipe drawing device is used, the outer circle of the small end of the pipe head 2 is tensioned by a pipe drawing on a lathe tailstock, and the outer circle of the large end of the pipe head 2 is in transition fit with the stepped hole of the sleeve 1, so that the sleeve 1 and the pipe head 2 are kept relatively static. Use the dabber clamp plate to fix on the main shaft wire winding part product, in the hole stopper of wire winding through the bearing 3 of this frock other end entered sleeve pipe 1, when wire winding length was shorter, the wire winding drove one end bearing rotatory, when wire winding length was great, the wire winding drove both ends bearing rotatory. Through the use of this rotatory frock, in taking in the sleeve pipe 1 with the wire winding, prevented that the wire winding is impaired in the course of working, played the effect of protection wire winding.

As shown in fig. 2, the sleeve 1 is a hollow cylinder, and has a stepped hole 4 formed therein for fitting with the bearing 3 and the pipe head 2, and the remaining hollow portion of the sleeve is used for accommodating the winding. The inner wall of the sleeve 1 is matched with the excircle of the selected bearing 3 during processing, so that the transition matching relation between the two is ensured.

As shown in fig. 3, the pipe head 2 is a rotary stepped shaft, the small end is used for tensioning and fixing a tail frame pull pipe of a lathe, and the large end is used for transitionally matching with the stepped hole 4 of the sleeve 1 to keep the sleeve fixed. The outer circle of the large end of the tube head 2 is matched with the step hole 4 in the sleeve 1 for processing, and the transition matching relation between the tube head and the step hole is ensured.

Compare with the protection scheme of wire winding class product coil in the past, the utility model discloses main advantage is: firstly, links of winding, adhesive tape bonding and adhesive tape removing in the process of processing winding products are reduced; secondly, the reliability of winding protection is improved, and the probability of winding damage is greatly reduced; thirdly, the operation is simple and fast, and the processing efficiency and the processing quality of parts are further improved.

The embodiments of the present invention are only described for the preferred embodiments of the present invention, and not for the purpose of limiting the conception and scope of the present invention, and various modifications and improvements made by the technical solutions of the present invention, such as changing the shapes of the pipe head and the casing, etc., should fall within the protection scope of the present invention.
