Technical Field
The utility model relates to a threaded end clamping tool for processing a double-end stud, and belongs to the technical field of double-end stud processing.
Background
The stud is one of the common parts used in equipment assembly, and the method for processing the stud by the prior art mainly comprises the steps of firstly processing threads at one end of a cylindrical part to be processed, then adopting an opening jacket with internal threads to be in threaded connection with the processed thread end of the part, then clamping the opening jacket by a three-jaw chuck, and then finishing the processing of threads at the other end. The prior art is a very troublesome problem in the processing and the disassembly of parts. The three-jaw chuck is small in clamping force to the open clamping sleeve, so that the part is easy to slip in the clamping sleeve, the processing of threads at the other end of the part is influenced, the clamping sleeve is easy to deform due to overlarge clamping force, the clamping sleeve and one threaded end obstinate of the part are dead, the part and the clamping sleeve are scrapped, and the production efficiency is low.
Disclosure of Invention
The utility model aims to solve the defects that the clamping force of an open jacket is difficult to control, slipping of the jacket is easy to cause or the clamping force is dead with a part obstinate and the like in the traditional stud processing technology, and provides a threaded end clamping tool for processing a stud.
The utility model aims at realizing the following technical scheme:
the utility model relates to a clamping tool for processing a threaded end of a stud, which comprises a threaded sleeve, a blanking cover and an open jacket;
the thread sleeve is a cylindrical part with internal threads matched with the threads of the processed threaded end of the stud product;
the plug is of a stepped cylinder structure, the diameter of the small cylinder section of the plug is smaller than the inner diameter of the nut, and the diameter of the large cylinder section of the plug is matched with the outer diameter of the nut;
the opening jacket is of a cylindrical structure with an opening at the upper end, the inner diameter of the opening jacket is matched with the outer diameter of the thread sleeve, and a tightening notch is axially formed in the side wall of the opening jacket;
the length of the threaded sleeve minus the length of the small cylindrical section of the plug is not greater than the length of the processed threaded section of the stud product, and the length of the inner cavity of the opening jacket is not greater than the length of the threaded sleeve plus the length of the large cylindrical section of the plug;
the plugging cover and the threaded sleeve are sequentially arranged in the inner cavity of the opening jacket, the lower end face of the plugging cover is tightly pressed against the step face of the plugging cover, the opening jacket is tightly clamped by the three-jaw chuck, and the opening jacket is tightly clamped and fixed with the threaded sleeve after being contracted and deformed.
An annular positioning table is arranged on the outer wall of the upper port part of the opening clamp sleeve, and the opening clamp sleeve and the three-jaw chuck are axially positioned through the annular positioning table.
Working process
And screwing one end of the processed thread of the stud product into the inner hole of the thread sleeve until the end part of the thread section of the stud product tightly abuts against the upper end surface of the small cylindrical section of the plug cover, and then processing the thread at the other end of the product by using a threading die or a threading tool. After the processing is finished, the three-jaw chuck is loosened, the stud product, the threaded sleeve and the blocking cover are taken out of the inner cavity of the opening jacket together, the blocking cover is detached from the lower end of the threaded sleeve, and finally the stud product is screwed out of the threaded sleeve.
Advantageous effects
The clamping tool disclosed by the utility model is simple in structure and convenient to use, can be used for reliably clamping the threaded end of the stud, can be easily disassembled, improves the processing efficiency of the stud, ensures the processing quality of the stud, and has important popularization and application values.
