Abstract

The utility model relates to a part clamping fixture, in particular to a fixture for a hydraulic clamping vehicle for thin-walled parts, which comprises a fixture body, wherein a clamping headstock is arranged on the right of the fixture body; a positioning cylinder is arranged on the right of the clamping headstock; an axial positioning disk is arranged on the right of the positioning cylinder; spring clamping heads are arranged outside the axial positioning disk; the positioning cylinder is connected with the axial positioning disk through a first hexagon socket screw; the fixture body and the clamping headstock are connected with the positioning cylinder through a second hexagon socket screw; a baffle bolt is arranged on the positioning cylinder; and a slot is arranged between the spring clamping heads. In theory, the fixture provided by the utility model exerts a resultant force of the radial forces of 0 to a workpiece, so as to effectively prevent the thin-walled parts from deforming due to the radial force. The fixture provided by the utility model is suitable for machining the inner bore and the end face of all thin shaft sleeve type parts, particularly suitable for semi-circular thin-walled parts similar to bearing pads, and the use effect is good.

Description

Thin-walled cover part hydraulic clamp vehicle clamper
Technical field
The utility model relates to the part clamping device, especially a kind of thin-walled cover part hydraulic clamp vehicle clamper.
Background technology
Need in the enterprise production process to use some parts are carried out machining, what workpiece was processed is to be installed on the lathe, various different types of workpieces need different anchor clamps to fix, adopt manually fixing mode now for semicircle type thin-walled cover workpiece, such installation way is installed trouble and is interrupted cut when adding endoporus and end face, " cutter relieving " situation is serious, and the workpiece end face that processes and the perpendicularity of axial line can not be guaranteed.
Summary of the invention
The deficiency that causes " cutter relieving " in order to overcome the fixing circle of existing no special anchor clamps type thin-walled cover workpiece: the utility model provides a kind of thin-walled cover part hydraulic clamp vehicle clamper.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of thin-walled cover part hydraulic clamp vehicle clamper, comprise clamp body, described clamp body the right is provided with the dop seat, described dop seat the right is provided with positioning tube, described positioning tube the right is provided with the axial location dish, described axial location dish outside is provided with spring chuck, described positioning tube adopts hexagon socket head cap screw one to be connected with the axial location dish, described clamp body, the dop seat adopts hexagon socket head cap screw two to be connected with positioning tube, described positioning tube is provided with the baffle plate bolt, be provided with fluting between the described spring chuck, be provided with rubber gasket between the described fluting, described clamp body and spring chuck contact-making surface are the tapering shape, and tapering the best is 3 °~10 °.
The beneficial effects of the utility model are: this thin-walled cover part hydraulic clamp vehicle clamper utilizes hydraulic cylinder pulling dop seat to axially move, the dop seat drives spring chuck and axially moves, thereby make spring chuck radially apply radial load to workpiece uniformly, and clamping work pieces, because it is zero that the radial load that these anchor clamps apply workpiece is in theory made a concerted effort, so can effectively prevent thin-wall part is subjected to radial load and is out of shape, these anchor clamps are suitable for the endoporus of all thin axle sleeve class parts and the processing of end face, be particularly useful for the semi-circular thin-wall part part of similar bearing shell class, result of use is good.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a front view of the present utility model;
Fig. 3 is the vertical view of spring chuck of the present utility model;
Fig. 4 is the front view of spring chuck of the present utility model;
Among the figure 1, clamp body, 2, the dop seat, 3, positioning tube, 4, spring chuck, 5, hexagon socket head cap screw one, 6, axial location dish, 7, the baffle plate bolt, 8, hexagon socket head cap screw two, 9, fluting.
The specific embodiment
As Fig. 1 is structural representation of the present utility model, a kind of thin-walled cover part hydraulic clamp vehicle clamper, comprise clamp body 1, described clamp body 1 the right is provided with dop seat 2, described dop seat 2 the right are provided with positioning tube 3, described positioning tube 3 the right are provided with axial location dish 6, described axial location dish 6 outsides are provided with spring chuck 4, described positioning tube 3 adopts hexagon socket head cap screw 1 to be connected with axial location dish 6, described clamp body 1, dop seat 2 adopts hexagon socket head cap screw 28 to be connected with positioning tube 3, described positioning tube 3 is provided with baffle plate bolt 7, be provided with fluting 9 between the described spring chuck 4, be provided with rubber gasket between the described fluting 9, described clamp body 1 and spring chuck 4 contact-making surfaces are the tapering shape, and tapering the best is 3 °~10 °.
This thin-walled cover part hydraulic clamp vehicle clamper, in running, clamp body 1 is installed on the lathe, dop seat 2 is connected with hydraulic pressure draw-bar on the lathe, workpiece is put on the anchor clamps, start lathe then, hydraulic pressure draw-bar pulling dop seat 2 is axially moved, and dop seat 2 drive spring chucks 4 are done radial motion, and the contact-making surface of clamp body 1 and spring chuck 4 is provided with tapering, when dop seat 2 pulling spring chucks 4 move like this, because the existence of tapering, spring chuck 4 is inwardly done radial motion, so just can guarantee the radial pressure unanimity that 4 pairs of workpiece of spring chuck apply, making a concerted effort of so just having guaranteed that workpiece is subjected to is zero, and workpiece just can not produce distortion, " cutter relieving " situation just can not appear when workpiece is processed like this, and axial location dish 6 need to guarantee the workpiece of processing vertical with machine tool chief axis, and the workpiece end face that processes like this and the perpendicularity of axial line are guaranteed, and the instrument that processes satisfies production requirement.
