The clamping mechanism can effectively solve the deformation problem of a workpiece in the process of positioning and clamping, and improve the processing accuracy of the bottom surface of a cylinder and a technique pin hole at the bottom surface. The clamping mechanism has the advantages of simple structure, low manufacturing cost, convenient installation and use, high reliability and the like.
Description
Technical field
The utility model relates to a kind of clamp mechanism with the thrust surface location, is used for vertical machining centre finish-milling cylinder of diesel engine bottom surface and processing bottom surface technology pin-and-hole.
Background technology
Cylinder of diesel engine bottom surface and bottom surface technology pin-and-hole have higher required precision as the subsequent technique benchmark, the processing precision direct influence of these key positions is to the machining accuracy of cylinder of diesel engine subsequent handling (as cylinder block end face, main bearing hole, camshaft hole, cylinder hole etc.), and is closely related with the performance and the service life of diesel engine.In the operation with vertical machining centre finish-milling cylinder of diesel engine bottom surface and processing bottom surface technology pin-and-hole, when the axial freedom of restriction cylinder block main bearing hole, typically use the end face location of cylinder block.But because the product design benchmark is the thrust surface on the main bearing seat, so the weak point of above-mentioned locate mode is location benchmark and design basis disunity, the processing accumulated error has influenced final machining accuracy.In the operation of processing cylinder block bottom surface and bottom surface technology pin-and-hole, desirable locate mode is to locate with thrust surface, but the bottom surface of cylinder block up at this moment, thrust surface is in the middle bearing bracket side of workpiece, on the higher position of anchor clamps base plate, in addition owing to be subjected to spatial constraints between cylinder block cylinder hole and the main bearing seat, positioning support can only be made the longaxones parts of chamfered edge, and rigidity is obviously not enough, is easy to produce distortion, influence machining accuracy when clamping work pieces.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of clamp mechanism that can effectively solve workpiece problem on deformation in location, clamping process.
A kind of clamp mechanism with the thrust surface location mainly is made up of positioning support, thrust surface locating piece, clamping part; Described thrust surface locating piece is contained in by screw on the side of positioning support, and described clamping part is arranged in the U groove of positioning support and thrust surface locating piece top.
Preferably, described clamping part comprises hold-down bolt, pressing plate, band shoulder nut, guider screw; One end of hold-down bolt is placed on the U groove of positioning support and thrust surface locating piece, and the other end is equipped with pressing plate and band shoulder nut, and described guider screw is contained in the screw of pressing plate top.
Preferably, described clamp mechanism also comprises the anchor clamps base plate, and described positioning support is installed on the anchor clamps base plate and by straight pin and fixes.
Preferably, described clamp mechanism fuses cylinder block and anchor clamps base plate, is used for finish-milling cylinder of diesel engine bottom surface and processing bottom surface technology pin-and-hole.
Because all there is the U-shaped opening top of positioning support and thrust surface locating piece, clamping part can mount and dismount easily and quickly.
This clamp mechanism fuses cylinder block and anchor clamps base plate by hold-down bolt, positioning support, thrust surface locating piece, pressing plate, band shoulder nut, because cylinder block and positioning support, thrust surface locating piece, pressing plate suffered power in clamping process all are the internal force of symmetry, can cancel each other, solve the problem on deformation of workpiece in location, clamping process effectively, improved the machining accuracy of cylinder block bottom surface and bottom surface technology pin-and-hole.
