Description

Stud Bolt Mount Apparatus [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stud bolt mounting apparatus for fastening and fixing one end of a stud bolt to a female screw formed on various mechanical elements, and more particularly, by mounting a stud bolt &Lt; / RTI >

In general, stud bolts are screws with male threads at both ends, and are used when holes that penetrate into machine elements can not be drilled. Such a stud bolt is used for assembling or disassembling a part by semi-permanently screwing one end of the stud bolt into a female screw part formed in a mechanical element such as a predetermined product or part, and screwing or loosening a nut at the other end.

On the other hand, as a method for screwing the stud bolt into a female screw portion such as a mechanical element, there is a method of screwing the stud bolt to the female screw portion of the machine element by rotating one side of the stud bolt with a tool such as a wrench In this case, there arises a problem that the thread formed at the portion of the tool, such as a wrench, is broken.

Accordingly, when the stud bolt is to be mounted on the machine element, a single nut is fastened to the stud bolt, and then the second nut is fastened tightly to the fastened nut so that the stud bolt and the nut can not move with each other. A part of the stud bolt is fastened to the mechanical element to be attached and the second nut is rotated using a tool such as a wrench in a state in which a tensile force is applied to the engaged thread of the stud nut and the stud bolt, And then detaching the nuts from the stud bolts.

However, in the case of mounting the stud bolts by the above-described method, it is necessary to tighten the two nuts in order, to separate the nuts after the stud bolts are mounted, thereby prolonging the working time, and in order to adjust the protruding height of the stud bolts It is inconvenient to measure the protruding height of the stud bolt several times through the measuring tool.

In addition, since the work of mounting the stud bolts is mostly performed by hand, the productivity is low and the cost competitiveness of the product is deteriorated.

Meanwhile, as a result of investigation of the prior art related to the present invention, several patent documents can be retrieved, and some of them will be described as follows.

Patent Document 1 discloses a stud bolt fastening device that is screwed to a hollow portion of a holder and has a hollow portion in a longitudinal direction thereof, A stud bolt is screwed to press the stud bolt and a handle provided on the outer circumferential surface of the holder to fix the protruding height of the stud bolt accurately and to easily mount the stud bolt to a predetermined product or part Device.

Patent Document 2 discloses a rail comprising a lower portion of a multi-stud stretcher, which is disassembled and assembled; A cleaning and removing device movably installed on the rail and detachably attaching the stud bolts and nuts provided on the multi-stud elongator to clean and re-install the stud bolts and nuts; And a control unit for automatically or manually controlling the washing and drying machine and the washing and discharging machine, thereby making it possible to reduce the work time to a minimum and to reduce the working time, Which can increase the efficiency of the stud bolt cleaning, such as to prevent the spreading of the workpiece, to prevent diffusion of the workpiece, to protect the worker from chemicals such as cleaning liquid, and to increase the utilization of the work space in the containment building. .
