Abstract
The invention relates to the field of tool accessories, in particular to a spiral adjusting thimble device. The spiral adjusting thimble device comprises a barrel-shaped shell, the barrel-shaped shell is provided with a closed port, a through hole is formed in the center of the closed end, in the barrel-shaped shell, a first thimble is arranged in the through hole in the center of the closed end, the upper end of the first thimble is connected with a spring with flat blocks at two ends, a second through hole is formed in the center of the flat block at the upper end of the spring, and threads are formed in the second through hole; the spiral adjusting thimble device further comprises a second thimble connected with the second through hole through the threads, an adjusting device is arranged at the upper end of the second thimble, the adjusting device comprises a rotary end, the rotary end is connected with the end of the second thimble through a screw rod, and the diameter of the screw rod is larger than the diameter of the second thimble. The spiral adjusting thimble device is aimed to reduce the stress on the workpiece surface and protect the workpiece surface from damage when fixing a workpiece.
Description
Technical field
The present invention relates to tool fitting field, particularly point out a kind of adjustable diameter and screw adjusting push pin device.
Background technology
To in the fixation procedure of workpiece, usually adopt fixture to be fixed, conventional brace is when fixing, be mostly rigid formula to fix, namely after fixing, position, this kind of fixed form can not during workpiece, arbitrarily be changed, in some cases, such as needing with changing fixed position, just seeming inconvenient, in addition, also have and adopt thimble to be fixed, and thimble easy especially formation surface of the work when fixing damages.
Summary of the invention
The object of the invention is to propose adjustable diameter and screw adjusting push pin device, mainly in workpiece fixation procedure, reduce the oppressive force to surface of the work, ensure that surface of the work is injury-free.
The technical scheme realizing the object of the invention is as follows:
Adjustable diameter and screw adjusting push pin device, comprise cylindrical case, described cylindrical case is provided with a close port, described closing end center is provided with through hole, in described cylindrical case, the first thimble is provided with in the through hole at closing end center, the first described thimble upper end is connected with two ends with the spring of smooth piece, smooth piece of center of described spring upper end is provided with the second through hole, screw thread is provided with in the second described through hole, also comprise the second thimble be threaded connection with the second through hole, the second described thimble upper end is provided with adjusting device, described adjusting device comprises round end, described round end is connected with the second thimble termination by screw rod, described screw diameter is greater than the diameter of the second thimble.
Further, be provided with spacing preiection in the middle of described screw rod, described spacing preiection cross section is trapezoidal, and the minor face in cross section is towards the second thimble direction.
Further, the sidewall of described cylindrical case is provided with for fixing recessed groove.
Further, described spring total length is 1.5 times of the second thimble total length.
After adopting said structure, the invention has the beneficial effects as follows: the position being regulated the second thimble by described round end, owing to being provided with spring in the second thimble lower end, when adjustment the second thimble, second thimble will be subject to the reaction force of spring, when end in contact under the lower end and the first thimble of the second thimble, oppressive force is formed to the first thimble, first thimble is fixed surface of the work, when using device proposed by the invention, first thimble is fixed workpiece, second thimble provides pretightning force, spring provides buffering, triplicity effectively protects surface of the work not sustain damage, there is practicality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Adjustable diameter and screw adjusting push pin device, comprise cylindrical case 1, described cylindrical case 1 is provided with a close port, described closing end center is provided with through hole, in described cylindrical case 1, the first thimble 2 is provided with in the through hole at closing end center, the first described thimble 2 upper end is connected with two ends with the spring 4 of smooth piece 3, smooth piece of 3 centers of described spring 4 upper end are provided with the second through hole, screw thread is provided with in the second described through hole, also comprise the second thimble 5 be threaded connection with the second through hole, the second described thimble 5 upper end is provided with adjusting device, described adjusting device comprises round end 6, described round end 6 is connected with the second thimble 5 termination by screw rod 7, described screw rod 7 diameter is greater than the diameter of the second thimble.
According to above-mentioned structure; its operation principle is; the position of the second thimble is regulated by described round end; owing to being provided with spring in the second thimble lower end; when adjustment the second thimble; second thimble will be subject to the reaction force of spring; when end in contact under the lower end and the first thimble of the second thimble; form oppressive force to the first thimble, the first thimble is fixed surface of the work, when using device proposed by the invention; first thimble is fixed workpiece; second thimble provides pretightning force, and spring provides buffering, and triplicity effectively protects surface of the work not sustain damage.
Spacing preiection is provided with in the middle of described screw rod, described spacing preiection cross section is trapezoidal, and the minor face in cross section is 1.5 times of the second thimble total length towards the second thimble direction and described spring total length, this structure further ensures that the second thimble can provide effective pretightning force, the first thimble firmly can not be fixed simultaneously.The sidewall of described cylindrical case is provided with for fixing recessed groove.Effectively entirety of the present invention can be placed on effective position, for single unit system provides effectively fixing.
