Abstract
The invention discloses a kind of clamp for machining of crankshaft journal, including fixed disk (1), chuck (2) and center sleeve (3), fixed disk is provided with some center holes on (1), center sleeve (3) is installed in center hole, and fixed disk (1) is connected with chuck (2) by jackscrew (4)；The chuck (2) includes circular ring shape clamping section (2.1) and the tight lock part (2.2) for being located at clamping section lower end, the positioning datum and correction reference of the center hole and fixed disk respectively as fixture.The configuration of the present invention is simple, the high bent axle of required precision suitable for mass production, greatly improves processing efficiency and machining accuracy.
Description
Technical field
The present invention relates to a kind of fixture, and in particular to a kind of clamp for machining of crankshaft journal, belongs to forging equipment technology neck
Domain.
Background technology
Bent axle is the main parts size of crank press transmission campaign and power, and crank shaft blank part uses forging mostly, bent
The mechanical processing of handle is complicated, the especially processing of rotor journal, since eccentricity difference is, it is necessary to make the eccentric Kong Tong of centre bore
It is no it will cause axle journal deviation from circular from one axis, and increase the parallelism error of axle journal and rotor journal, therefore also need to increase
If the processing of high progress boring and milling machine is eccentric empty, and adds that Upsetting is thick or the process of welding procedure platform, so as to cause processing program numerous
It is trivial, it is difficult to mass production.
The content of the invention
To solve the above problems, the present invention provides a kind of clamp for machining of crankshaft journal, the processing essence of crankshaft journal is improved
Degree and processing efficiency.
To achieve these goals, a kind of clamp for machining of crankshaft journal of the present invention, including fixed disk, chuck and top
Cover, some center holes are provided with fixed disk, center sleeve is installed in center hole, and fixed disk is connected with chuck by jackscrew；It is described
Chuck includes circular ring shape clamping section and the tight lock part for being located at clamping section lower end, and the center hole and fixed disk are respectively as fixture
Positioning datum and correction reference.
This fixture be more suitable for high-volume and interchangeability it is strong crankshaft journal processing, by fixture be installed on axle journal crankshaft two end
And the tight lock part of locking fixture, then it is processed, the bent axle of installation is positioned by center hole, improves determining for fixture
Position precision, simultaneously clamps on mode very simple, is easily adjusted, so as to substantially increase the processing efficiency and machining accuracy of fixture.
Further, the clamping section of the chuck is equipped with three eccentric correction jackscrews, the angle difference between three jackscrews
For 120 °.The offset of bent axle is corrected by adjusting three jackscrews.
Further, the fixed disk is square.
Further, the tight lock part of the clamping section lower end of chuck is locked by the bolt and nut crossed.
The configuration of the present invention is simple, the high bent axle of required precision suitable for mass production, greatly improves processing efficiency and processing essence
Degree.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention；
Fig. 2 is sectional view along A-A in Fig. 1.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, a kind of clamp for machining of crankshaft journal, including fixed disk 1, chuck 2 and center sleeve 3, it is fixed
Some center holes are provided with disk 1, center sleeve 3 is installed in center hole, and fixed disk 1 is connected with chuck 2 by jackscrew 4；The folder
Set 2 includes circular ring shape clamping section 2.1 and is located at the tight lock part 2.2 of clamping section lower end, the center hole and fixed disk respectively as
The positioning datum and correction reference of fixture.
This fixture be more suitable for high-volume and interchangeability it is strong crankshaft journal processing, by fixture be installed on axle journal crankshaft two end
And the tight lock part of locking fixture, then it is processed, the bent axle of installation is positioned by center hole, improves determining for fixture
Position precision, simultaneously clamps on mode very simple, is easily adjusted, so as to substantially increase the processing efficiency and machining accuracy of fixture.
Further, the clamping section of the chuck 2 is equipped with three eccentric correction jackscrews 5, the angle between three jackscrews 5 point
Wei not be 120 °.The offset of bent axle is corrected by adjusting three jackscrews 5.
Further, the fixed disk 1 is square.
Fixture processing is as follows：
It is rough turn：Fixture is installed on to the crankshaft two end of rough turn good axle journal, locking screw on chuck is screwed after being corrected on platform
Bolt makes clamp bent axle, then lifts to lathe, rough turn middle rotor journal；Half smart car：First half smart car after bent axle is quenched
Both ends axle journal land mill amount, then loads onto fixture, is clamped after correction bias and cross hairs, car rotor journal stays mill amount；Grinding：
The bent axles of more than half smart cars is loaded into fixture, is clamped after correction and hangs on grinding machine, respectively on the basis of center hole, be ground crankshaft journal and
Eccentric part is to required precision.
