The technical solution in the present invention is further illustrated with reference to the accompanying drawings and embodiments.
It please refers to shown in Fig. 1-Fig. 5, the invention proposes a kind of locating tensioning devices, comprising:
Cylinder body 10,10 bottom of the cylinder body closing, top opening；
The cylinder sleeve 20 being fixed in the cylinder body 10, the cylinder sleeve 20 stretch out the top opening of the cylinder body 10
And sealed with the opening inner wall, up and down in the cylinder sleeve 20 to be provided with tighting rod 21,21 bottom end of tighting rod connects
It is connected to and compresses conehead 22, top is fixedly connected with addendum cone 23, and the conehead of the addendum cone 23 is fixedly connected with the tighting rod 21, institute
State and be also arranged with tensioner tapered sleeve 24 outside tighting rod 21, the 24 bottom connecting cover plate 25 of tensioner tapered sleeve, the cover board 25 with it is described
Cylinder sleeve 20 is fixedly connected, and is pyramidal structure at the top of the tensioner tapered sleeve 24, and the conehead of tensioner tapered sleeve 24 is towards the addendum cone 23,
Tensioner 26 is also movably provided on tighting rod 21, the tensioner 26 is between addendum cone 23 and tensioner tapered sleeve 24；It is described
It is further fixedly arranged on 20 roof of cylinder sleeve and compresses frustum 40, the compression frustum 40 is in an inverted cone, and outside the compression frustum 40
The taper of wall is suitable with the open-topped taper of reinforcement set 31, and compression 40 bottom end of frustum is provided with taper upward
Mouth 41, the taper of the conical opening 41 is suitable with the compression taper of conehead 22, and the compression frustum 40 is bored with the compression
The decorative pearl on top of an official cap 42 is freely provided between first 22；
The cylinder sleeve 20 is separated by the movable step-up system 30 being arranged in the cylinder sleeve 20, the step-up system 30
The upper cavity 27 and lower cavity 28 of sealing, the compression conehead 22 are located in upper cavity 27,27 He of upper cavity
Under not cavity 28 be in communication with the outside by the through hole opened up on cylinder sleeve 20 and cylinder body 10,30 bottom of step-up system and cylinder
The spring 14 that normality is in compressive state is fixedly installed between the bottom plate 12 of body 10, the step-up system 30 is in the spring 14
Elastic force effect decline the decorative pearl on top of an official cap 42 indentation compress conehead 22 and compress frustum 40 between tapered surface, thus will compress conehead 22 to
Lower compression, and under the state, the addendum cone 23 of compressor arm 21 and compresses conehead 22 for 26 tensioner of tensioner.
Wherein, as shown in figure 4, the step-up system 30 includes that reinforcement covers 31 and the close of 31 outer walls of the reinforcement set is arranged in
Seal ring 32, the reinforcement cover the closing of 31 bottoms, and top opening is tapered, and air inlet duct 34 is offered on the tapered surface at top, institute
It states reinforcement and covers 31 outer walls and be provided with and cooperate boss 33, the sealing ring 32 is fixedly connected at the boss 33.
When in use, compressed spring 14 compresses step-up system 30 to top to above scheme, so that step-up system 30
The decorative pearl on top of an official cap 42 is pressed into and compresses conehead 22 and compresses the tapered surface between frustum 40, so that compressor arm 21 moves downward, the shape
Under state, addendum cone 23 and tensioner tapered sleeve 24 are by 26 tensioner of tensioner, to realize under normal conditions, tensioning device is in tensioner shape
State, to substantially increase the reliability of the tensioning device departing from the status for relying on air pressure progress tensioner, reduce failure
Rate.
Preferably, as shown in figure 5,26 inner wall of the tensioner is the bipyramid being adapted to the addendum cone 23 and tensioner tapered sleeve 24
Shape structure.The inner wall of tensioner 26 is arranged to can be into cone 23 surely and the biconial structure that can cooperate of tensioner tapered sleeve 24
One step improves the mating capability of tensioner 26 and addendum cone 23 and tensioner tapered sleeve 24, thus in tensioner, by boring 23 and tensioner cone surely
Set 24 compresses simultaneously from the both ends of tensioner 26, ensure that the reliability of tensioner, at this point, using tensioner 26 under tensioner state
The workpiece tensioner that the expansion of external dimensions clamps needs, ensure that the reliability of workpiece tensioner.
Preferably, as shown in figure 5, offering a plurality of tensioner mouth 261 on 26 outer wall of the tensioner, a plurality of tensioner mouth
261 be successively spaced run through with 26 top and bottom of tensioner.Also it also is provided with tensioner mouth in traditional tensioner, but tensioner mouth
Be set as a tensioner mouth is offered from an end face vertical, in this setup, a plurality of tensioner mouth runs through with same end face,
So that when deformation of tensioner during tensioner, can only one end expand, so that it is different upper and lower side tensioner degree occur
Situation, directly results in that tensioner both ends expanding force is inconsistent, and this tensioner mode will lead to tensioner both ends and rise to workpiece
It is tight uneven, and then it is easy to appear the case where one end loosens in processing, it influences to process, reliability is low, in the present solution, by tensioner
Set 26 tensioner mouth 261 using a plurality of tensioner mouth 261 be successively spaced with the perforative mode in 26 top and bottom of tensioner, thus
So that 26 both ends of tensioner can expand simultaneously dehisces, to ensure that the expansion of 26 upper and lower ends of tensioner during tensioner
Mouth degree is identical, to ensure that the reliability of 26 tensioner of tensioner.
Preferably, the upper and lower part of the cylinder body 10 offers through-hole, wherein in lower through-hole 11 and cylinder sleeve 10
Lower cavity 28 is connected to, and upper through-hole 12 is connected to upper cavity 27, and upper through-hole 12 connects compressed air system when in use.
Under normal conditions due to the tensioning device in the present invention, tensioner 26 is in tensioner state, when needing to remove workpiece, needs from upper
Portion's through-hole 12 is passed through compressed air, after compressed air enters upper cavity 27 from upper through-hole 12 and air inlet duct 34 and on
When pressure in portion's cavity 27 is greater than the elastic force of spring 14, step-up system 30 moves downward under the gas pressure of upper cavity,
The gap for compressing conehead 22 at this time and compressing between frustum 40 becomes larger, and reinforcement covers 31 tapered opening in step-up system 30
To bottom offset, so that the decorative pearl on top of an official cap 42 being freely arranged moves downward under the effect of gravity, then compressor arm 21 is in not by outer
Power state realizes pickup so that tensioner 26 is released, since the lower part of cylinder body 10 also offers lower through-hole 11,
When step-up system 30 is to bottom offset, the air in lower cavity 28 is discharged by lower through-hole 11, is avoided in lower cavity 28
The displacement of effects of air pressure step-up system 30.
Preferably, the cylinder body 10 has the bottom plate 13 of removable connection.The bottom plate 13 of cylinder body 10 is arranged to detachably
Formula structure, can in order in process of production assembling and failure need repairing when disassembly.
Preferably, pass through bolt detachable connection with the cylinder sleeve 20 on the cover board 25.By cover board 25 and cylinder sleeve 20
Be arranged to Demountable, can in order in process of production assembling and failure need repairing when disassembly.
Finally, it is stated that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although referring to compared with
Good embodiment describes the invention in detail, those skilled in the art should understand that, it can be to skill of the invention
Art scheme is modified or replaced equivalently, and without departing from the objective and range of technical solution of the present invention, should all be covered at this
In the scope of the claims of invention.
