The utility model has simple structure, easy processing and convenient, rapid and effective operation; the problem of high-efficient repair double-screw bolt screw thread inefficacy is realized, process flow has been simplified and the space operation inconvenience has been avoidd, has practiced thrift the time of reprocessing to promote and produce the line beat, promote production efficiency.

Description

Quick round die tool

Technical Field

The utility model relates to a production line technical field especially relates to a swift round die instrument.

Background

In an automobile manufacturing factory, a welded body-in-white assembly enters a final assembly workshop after being coated, electrophoretically sprayed with paint. The installation and connection of a large number of accessories such as automotive interior parts, wiring harnesses, heat insulation plates and the like and automobile body metal plates are mainly realized by stud nuts. More than 40 studs are required for each attachment, and as many as 100 studs are required. Stud and sheet metal component adopt the fixed of stud welding's mode, generally use the welding of welding machine projection welding and stud welding gun of falling to the ground, and its quantity in automobile manufacturing is increasing day by day. The two welding processes are both adopted, and the stud is put into the lower electrode of the projection welding machine or a stud welding gun for welding. The two processes may cause the loss of the thread on the stud, so that the stud fails, and the stud is knocked out and then welded with another stud in the same rule, so that the repair process can cause a series of consequences and consume a large amount of manpower and material resources, or common round dies are adopted for tapping, and the problems of difficult implementation, long repair time and the like are caused by the inconvenience of the operation space of part of studs. Therefore, an efficient and fast tool is needed to implement both of the above solutions.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the time high efficiency has fully been considered to the invention, and operation agility, actual effect and evade space restriction scheduling problem now provide a novel swift round die instrument, have realized that the high efficiency is reprocessed double-screw bolt screw thread problem of inefficacy, have simplified process flow and have evaded the space operation inconvenience, have practiced thrift the time of reprocessing to promote and produce the line beat, promote production efficiency. The specific technical scheme is as follows:

the utility model provides a swift round die instrument, the instrument includes a hollow round bar a round die is fixed to the one end of hollow round bar the other end correspondence of hollow round bar has seted up two trompils, and the movable handle penetrates two trompils, makes movable handle wholly cross hollow round bar the end cover is fixed at the both ends of movable handle.

Further, the round die is welded on the hollow round rod.

Further, the round die is provided with an internal thread, the hollow round rod is provided with an external thread, and the internal thread is in fit connection with the external thread.

Further, the end covers are welded at two ends of the movable handle.

Furthermore, the diameter of the movable handle is smaller than the preset opening of the hollow round rod.

Furthermore, the inner diameter of the hollow round rod is larger than the movable inner diameter of the round threading die.

The beneficial effects of the utility model reside in that: the tool has simple structure, easy processing and convenient, quick and effective operation; the problem of high-efficient repair double-screw bolt screw thread inefficacy is realized, process flow has been simplified and the space operation inconvenience has been avoidd, has practiced thrift the time of reprocessing to promote and produce the line beat, promote production efficiency.

Detailed Description

The invention is further illustrated below with reference to the following figures and examples:

with particular reference to figures 1-3 of the specification

The utility model provides a novel swift circular die instrument, its structure component lower extreme is 1 structures of standard circular die, and hollow round bar 2 is connected through welding mode to this embodiment, presets a pair of trompil that corresponds at 2 terminal departments of hollow round bar, alternates in the trompil with movable handle 3, and both ends adopt welding mode to weld end cover 4 to guarantee that movable handle does not drop

The working principle is as follows: in the production process, when the defect of stud thread failure is encountered, the invention is utilized to align the lower end of the stud with the standard round die 1 to the failed stud, firstly hold the hollow round rod 2 to rotate, ensure the round die 1 to be effectively contacted with the stud, and then utilize the movable handle 3 to rotate in a large range, and simultaneously, in order to avoid the limitation of space operation, the movable handle can rotate by taking one end as a fulcrum or the middle as the fulcrum, so as to effectively tap the stud and recover the stud thread structure.

Although the preferred embodiments of the present patent have been described in detail, the present patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the knowledge of those skilled in the art.
