Abstract
A crankshaft clamping unloading device relates to the improvement of a clamping device of a part of a large-scale grinder to be machined and is mainly used for a clamping device for grinding heavy parts and parts which need centering of center holes. The invention aims at providing a crankshaft clamping unloading device with simple structure and convenient operation. The crankshaft clamping unloading device comprises a part chuck, wherein, the structural key point is that: the outer edge of the part chuck is provided with a stud bolt which is connected with a main shaft chuck; a spring is arranged between a gland of the stud bolt and the part chuck; and the part chuck is provided with screws for fixing the parts.
Description
Technical field:
The present invention relates to the improvement of chucking device of the part to be processed of large-scale grinding machine; Be mainly used in the grinding heavy parts and need the chucking device of center hole centering part.
Background technology:
Generally speaking, the part that grinding length and diameter are bigger all adopts top center hole by part to support and is ground part, and set up the center support frame on the relevant position of grinder bed, and part is carried out grinding.But in the grinding process to bent axle, especially when grinding bent axle external diameter, all can't set up the center support frame to part.The grinding chucking device complex structure of state's inside crankshaft in the past, operation easier is bigger, and is difficult to guarantee machining accuracy; Now external advanced grinding chucking device is a numerical control device at present, its complex structure, and price is extremely expensive.
Summary of the invention:
The present invention is exactly at the problems referred to above, and unloading gear for crankshaft chucking a kind of simple in structure, easy and simple to handle is provided.
For achieving the above object, the present invention adopts following technical scheme, the present invention includes the part chuck, its structural feature is that the outer edge of part chuck is provided with the stud that links to each other with spindle chuck, is provided with spring between gland on the stud and the part chuck; But the part chuck is provided with the screw of retaining element.
Beneficial effect of the present invention:
1, simple in structure:
Main member of the present invention is the part chuck, and stud, the gland of stud and the spring between the part chuck on the part chuck, and its member is few and body is simple, is easy to make;
2, easy and simple to handle:
The present invention in use, it is parallel with spindle chuck mainly to set up the part chuck, executes spring and gets final product with certain tight power of giving, and operates extremely simple and easy to do.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the right view of Fig. 1;
Fig. 3 is the partial enlarged drawing of the A portion of Fig. 1.
The specific embodiment:
The present invention includes part chuck 6, the outer edge of part chuck 6 is provided with the stud 10 that links to each other with spindle chuck 4, is provided with spring 7 between gland 9 on the stud 10 and the part chuck 6; But part chuck 6 is provided with the screw 5 of retaining element 1.
Spring 7 can adopt butterfly spring, can bear to give tight power greatlyyer when being installed.Part chuck 6 in the butterfly spring is provided with guide finger 8, can limit the position of butterfly spring in motion process.
For example, three turn four supports bent axle, and apart from 255mm, bent axle diameter of phi 560mm adopts top support location, (bent axle supports axle center, three bent axle hearts) two ends, four axle center apart from the four supporting rotating shaft hearts for the long 3700mm of part, bent axle; Utilize the relief arrangement that is installed of the present invention to carry out grinding, the elastic range of adjusting the butterfly spring on the part chuck 6 of the present invention is 0.30mm or to give tight power be 4500 kilograms, carries out grinding then and gets final product.
Below in conjunction with a description of drawings use of the present invention:
At first, part 1 end is fixed on the part chuck 6 by screw 5, and then the stud 10 by part chuck 6 is fixed in part chuck 6 on the spindle chuck 4 on top 3; It is parallel with spindle chuck 4 to adjust part chuck 6; When adding man-hour, error during installation or main shaft 2 top 3 are all absorbed the external force of part 1 distortion by spring 7; The precision that has guaranteed part 1 under the precision that records and the nature in process is identical; Objectivity, the accuracy of in-process measurement have promptly been guaranteed.
