Abstract
Provided is a centre with big ejecting force. A piston cylinder is mainly arranged in a centre body, the centre is installed and fixed in an inner hole of the piston cylinder through a bearing, liquid plastic is injected in a space sealed by the piston cylinder and the centre body, and a method that the liquid plastic is compressed by an expansion screw is used for promoting the piston cylinder to move to clamp a workpiece. The centre has the advantages of big clamping force, can effectively achieve effects of clamping a big workpiece, and effectively avoids production quality and safety accidents caused by small clamping force on the workpiece.
Description
Technical field
The present invention relates to the horizontal lathe annex, it is top to be specifically related to horizontal lathe, relates in particular to that to have a larger pressure top, belongs to the machine tool accessories technical field.
Background technology
At present, lathe centre generally is exactly to have the top centrum, the centre is cylinder, afterbody is the bar-shaped simple structure of Morse's taper, in use, top Morse's taper by its afterbody is installed in the sleeve of lathe tailstock, drive top movement by the leading screw that is arranged in the tailstock, thereby reach the purpose of top tight workpiece, by existing top tip structure with and operation principle can find out, existing top clamping work pieces is to rely on passively the leading screw in the tailstock to produce active force fully, thereby and reach the purpose of clamping work pieces, so the force limited that produces is for the part of larger weight or dimensions, be not easy clamping work pieces, not only produce easily quality accident, simultaneously, also might produce security incident.
Summary of the invention
The object of the invention is to: for the top existing defects of existing lathe, the invention provides a kind of novel top, this kind be top to have larger clamping force, especially also can effectively reach the effect of clamping for relatively large workpiece, effectively avoid because the clamping force of workpiece is hanged down the possible quality of production and security incident.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: described a kind of larger pressure is top, comprise: top body, liquid plastics, the tensioner screw, piston cylinder, ring washer, bearing, spacer, circlip, top, friction top, disk spring, in the endoporus of top body front end, be provided with piston cylinder, in piston cylinder and the formed enclosure space of top body, be marked with liquid plastics, toply be installed in the endoporus of piston cylinder by two bearings, top cylindrical between two bearings is provided with spacer, described spacer and bearing inner race compress, endoporus inner end at piston cylinder is provided with ring washer, the described ring washer bearing outer ring close with it compresses, port part is provided with spring washer in the outside of piston cylinder, the described spring washer bearing outer ring close with it compresses, external edge port part setting at top body is equipped with friction top, and the top cylindrical between friction top and piston cylinder is provided with disk spring.
Using method of the present invention is: the present invention is directly installed in the sleeve of lathe tailstock, is driven with Workpiece clamping, afterwards by the leading screw in the sleeve first, turn the tensioner screw, impel liquid plastics to expand, the motion of pushing piston cylinder, so: just workpiece is clamped further.
Beneficial effect: can be found out by structure principle chart of the present invention and operation principle: the present invention has the larger advantage of clamping force, also can effectively reach the effect of clamping for relatively large workpiece, effectively avoid since to the clamping force of workpiece is low might the quality of production and security incident.
