Abstract
A kind of centering and clamping apparatus, belong to jig technical field, it mainly includes a centration axis being arranged on base, macropore is made among described centration axis, and in the waist of macropore it is to make the annular waist hole that is relatively large in diameter, make the centering axial wall at the position relatively thin, by injecting hydraulic medium in centration axis inner space, and the method expanded by piston pressurization hydraulic medium, the method for expanding outwardly annular waist hole centering axial wall, reach the purpose to workpiece centering, the present invention has the advantages of centering effect is preferable, precision is higher.
Description
Technical field
The present invention relates to a kind of centering and clamping apparatus, belongs to jig technical field.
Background technology
In production process is machined, in order to ensure the precision of converted products, some workpiece usually need centering to clamp, right
Workpiece carries out centering clamping and typically uses special centering and clamping apparatus, although existing centering and clamping apparatus is not quite similar,
A centration axis typically is used, the excircle dimension of the centering mandrel is the hole size according to workpiece, is coordinated with less gap
Tolerance dimension manufacture, it is clear that because the presence of manufacturing tolerance and location tolerance, centering effect are poor.
The content of the invention
It is an object of the invention to：For the centering effect present in existing centering and clamping apparatus it is poor the defects of, this hair
It is bright that a kind of preferable centering and clamping apparatus of new centering effect is provided.
A kind of centering and clamping apparatus of the present invention, it includes base（1）, described base（1）It is installed above to have calmly
Mandrel（2）, the centration axis（2）Middle part be formed with macropore（12）, in macropore（12）Waist location is made one section of diameter and is more than greatly
Hole（12）The ring-type waist hole of diameter（13）, the ring-type waist hole（13）The centration axis at position（2）With relatively thin wall thickness, big
Hole（12）Bottom be formed with small through hole（14）, centration axis（2）Pass through bolt（9）It is fixed on base（1）Above, pull bar（6）'s
Bottom passes through centration axis（13）The small through hole of bottom（14）Use nut（10）With base（1）It is fixed together, in centration axis（2）'s
Inner space is marked with hydraulic medium（8）, described hydraulic medium can be any one in hydraulic oil, butter, liquid plasticses,
Piston（4）Pull bar is connect by in-between borehole jack（6）Top, piston（4）Cylindrical be socketed in centration axis（2）Top macropore
（12）In, in piston（4）The pull bar on top（6）On screw thread cooperation by way of first nut is set（7）,
In the first nut（7）The pull bar on top（6）One pressing plate of upper socket（3）, further, described pressing plate（3）For
The downward bowl-type shape of the rim of a bowl, its rim of a bowl position is with being socketed in centration axis（2）Annular workpieces on cylindrical（11）Upper plane phase
Contact, in pressing plate（3）The pull bar on top（6）On screw thread cooperation by way of youngster's nut is set（6）.
Beneficial effect：The course of work of the present invention can be seen that by accompanying drawing：Tighten the first nut（7）Piston（4）Compress liquid
Press medium（8）, then：Centration axis（2）, so as to reach the purpose of centering, second is tightened to Western Zhou Dynasty expansion in the most thin position of wall portion
Nut（5）, then pressing plate（3）By workpiece（11）Do the positioning of vertical direction, it is clear that centration axis（2）Centering position it is cylindrical not
Influenceed by mismachining tolerance and service wear, there is the advantages of centering effect is preferable, precision is higher.
Brief description of the drawings
Fig. 1 is the front view of the present invention；
Fig. 2 is the concrete structure diagram of centration axis 2 in Fig. 1；
Shown in figure：1 is base；2 be centration axis；3 be pressing plate；4 be piston；5 be the second nut；6 be pull bar；7 be
