Abstract
The utility model provides a centering and clamping device, belongs to jig technical field, and it mainly is including a centering shaft who installs on the base, centering shaft in the middle of make the macropore to macroporous waist for making the great annular waist hole of diameter, make the centering shaft wall at this position thinner, through injecting the hydraulic pressure medium into at the centering shaft inner space, and through piston pressurization hydraulic medium expanded method, make the method of the outside expansion of annular waist hole centering shaft wall, reach the purpose to work piece centering, the utility model has the advantages of the centering effect is better, the precision is higher.
Description
Technical field
The utility model relates to a kind of centering and clamping apparatus, belongs to jig technical field.
Background technology
In machined production process, in order to ensure the precision of converted products, some workpiece usually need centering clamping, and carrying out feeling relieved clamping to workpiece generally adopts special centering and clamping apparatus, although existing centering and clamping apparatus is not quite similar, but a general employing centration axis, the excircle dimension of this centering axle is the hole size according to workpiece, manufactures, obviously with less matched in clearance tolerance dimension, due to the existence of manufacturing tolerance and location tolerance, centering effect is poor.
Utility model content
The purpose of this utility model is: for the defect that the centering effect existing for existing centering and clamping apparatus is poor, and the utility model provides a kind of novel centering effect good centering and clamping apparatus.
A kind of centering and clamping apparatus described in the utility model, it comprises base, described submounts is provided with centration axis, the middle part of described centration axis is shaped with macropore, the ring-type mounting hole that one section of diameter is greater than diameter macropores is made at macropore waist location, the centration axis at this ring-type mounting hole position has thinner wall thickness, small through hole is shaped with in the bottom of macropore, centration axis is bolted on above base, the bottom of pull bar is fixed together through the small through hole nut bottom centration axis and base, hydraulic medium is marked with in the inner space of centration axis, described hydraulic medium can be hydraulic oil, butter, any one in liquid plastics, the middle borehole jack of piston is connected with the top of pull bar, the cylindrical of piston is socketed in the top macropore of centration axis, the pull bar of upper piston area arranges first nut by the mode of threaded engagement, the pull bar on the first nut top is socketed a pressing plate, further, described pressing plate is the downward bowl-type shape of the rim of a bowl, its the rim of a bowl position is touched with the upper flat face being socketed in the annular workpieces on centration axis cylindrical, the pull bar on pressing plate top arranges second nut by the mode of threaded engagement.
Beneficial effect: the course of work of the present utility model is as can be seen from accompanying drawing: tighten the first nut piston compression hydraulic medium, so: expanded to the Western Zhou Dynasty in the position that centration axis wall portion is the thinnest, thus reach the object of centering, tighten the second nut, then workpiece is done the location of vertical direction by pressing plate, obviously, the cylindrical at the centering position of centration axis is not subject to the impact of mismachining tolerance and service wear, has the advantage that centering effect is better, precision is higher.
