Abstract
The invention discloses a centering clamping device and belongs to the technical field of machine tool clamps. The centering clamping device mainly comprises a centering shaft installed on a base. A large hole is formed in the middle of the centering shaft. An annular waist hole with a larger diameter is formed in the waist portion of the large hole, so that the centering shaft wall at the portion is thinner. By means of the method of pouring hydraulic media into the internal space of the centering shaft and using a piston for pressurizing the hydraulic media for expansion to enable the centering shaft wall of the annular waist hole to expand outwards, the workpiece centering purpose is achieved. The centering clamping device has the beneficial effects of being good in centering effect and high in precision.
Description
Technical field
The present invention relates to a kind of centering and clamping apparatus, belong 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.
Summary of the invention
The object of the invention is to: for the defect that the centering effect existing for existing centering and clamping apparatus is poor, the invention provides the good centering and clamping apparatus of a kind of novel centering effect.
A kind of centering and clamping apparatus of the present invention, it comprises base (1), described base (1) is provided with centration axis (2) above, the middle part of described centration axis (2) is shaped with macropore (12), the ring-type waist hole (13) that one section of diameter is greater than macropore (12) diameter is made at macropore (12) waist location, the centration axis (2) at this ring-type waist hole (13) position has thinner wall thickness, small through hole (14) is shaped with in the bottom of macropore (12), centration axis (2) is fixed on above base (1) by bolt (9), the bottom of pull bar (6) is fixed together through the small through hole (14) bottom centration axis (13) nut (10) and base (1), hydraulic medium (8) is marked with in the inner space of centration axis (2), described hydraulic medium can be hydraulic oil, butter, any one in liquid plastics, piston (4) connects the top of pull bar (6) by its middle borehole jack, the cylindrical of piston (4) is socketed in the top macropore (12) of centration axis (2), the pull bar (6) on piston (4) top arranges first nut (7) by the mode of threaded engagement,
The upper socket pressing plate (3) of pull bar (6) on the first nut (7) top, further, described pressing plate (3) 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 (11) on centration axis (2) cylindrical, and the pull bar (6) on pressing plate (3) top arranges youngster's nut (6) by the mode of threaded engagement.
Beneficial effect: the course of work of the present invention is as can be seen from accompanying drawing: tighten the first nut (7) piston (4) compression hydraulic medium (8), so: expanded to the Western Zhou Dynasty in the position that centration axis (2) wall portion is the thinnest, thus reach the object of centering, tighten the second nut (5), then workpiece (11) is done the location of vertical direction by pressing plate (3), obviously, the cylindrical at the centering position of centration axis (2) is not subject to the impact of mismachining tolerance and service wear, has the advantage that centering effect is better, precision is higher.
