Abstract
The utility model relates to a clamp belonging to the lathe universal class of mechanical processing. A liquid ejecting live center comprises a center main body and a center body, and the utility model is characterized in that the center main body (1) is composed of a cylindrical part and a mohs conical part which are at the same axial line, and the center main body (1) presents a hollow shape; cooling liquid is injected from a liquid inlet of the mohs conical part arranged in the main body (1) and is ejected out from a liquid ejecting nozzle (4) arranged ahead of the cylindrical part, and partial outer walls of the cylindrical part of the center main body (1) keep tight fits with the rotatable hollow conical center body (3) by a bearing (2); the maximal included angle of the conical bus line of the center body (3) is 90 DEG, and a liquid ejecting tool bar is characterized in that a main body (7) of the tool bar presents a hollow shape. When work pieces in sleeve class are processed, the liquid ejecting live center not only can play a clamping and positioning effect on the work pieces, but also can cool cutting surfaces of the work pieces and the liquid ejecting live center can realize the cooling for the inner and the outer circles when placed into a processing inner hole. The cutting heat is lowered, the abrasion of cutters is reduced and the processing efficiency and the processing precision are increased.
Description
Technical field:
The utility model belongs to lathe general class anchor clamps in the machining.
Background technology:
Present domestic lathe general class anchor clamps live center machine tool accessories can only play the clamping positioning action to shaft-like workpiece.Processing during sleeve workpiece by means of other annex.Because contact-making surface is little, locate insecurely, original live center is the inner axes rotation, the tapering angle is 60 to spend, and can only withstand shaft-like workpiece.
The inside and outside circle that original live center can not be implemented in the working angles cools off simultaneously.During processing thin-walled sleeve workpiece, workpiece rigidity deficiency, and in working angles, produce a large amount of heat in metal cuttings, workpiece easily produces distortion, especially when the processing stainless steel workpiece, stainless steel high temperature temperature height, the hardness high tenacity is big, and smear metal is frangibility not, poor thermal conductivity, the stainless steel adhesiveness is strong, easily produces chill phenomenon, and the aggravation tool wear influences machining accuracy.In processing during sleeve workpiece, except that will selecting the cutting-tool angle, cooling fluid cast using method is also very important.Original live center can not be implemented the cooling cast to workpiece.
In processing during sleeve workpiece, existing knife bar can not solve inside and outside circle and cools off simultaneously during the processing endoporus.
The utility model content:
The utility model provides a kind of use liquid-spraying type live center can play the clamping workpiece positioning action, reach sufficient cooling workpiece cutting surface in the working angles again, reduce heat in metal cutting greatly, reduce tool wear in the working angles, prolong cutter life, shorten machining period, improve working (machining) efficiency, reduce workpiece deformation, improved machining accuracy, made product quality be further enhanced.
The hydrojet live center that the utility model provides comprises top main body, and top body is characterized in that, this top main body 1 is made of same circular cylinder shaped portion that is fixed together and Mohs conical section on an axis; Establish the straight-through endoporus that is used to be equipped with cooling fluid on the above-mentioned axis in this top main body 1, be hollow shape, cooling fluid is injected from the inlet that is located on the main body 1 Mohs conical section, from spray nozzle 4 ejections that are arranged on circular cylinder shaped portion the place ahead;
The cylindrical shape part outer wall of top main body 1 closely cooperates by bearing 2 with the hollow round table-like top body 3 that can rotate; The round platform bus maximum angle of this top body 3 is 90 degree.
The liquid-spraying type knife bar is characterized in that, establishes the straight-through endoporus that is used to be equipped with cooling fluid on knife bar main body 7 axis, is hollow shape, and cooling fluid is injected from the inlet that is located on the knife bar main body 7, from spray nozzle 4 ejections that are arranged on knife bar main body 7 the place aheads.
When the processing sleeve workpiece, the liquid-spraying type knife bar can realize that inside and outside circle cools off simultaneously when the processing endoporus.Reduce heat in metal cutting greatly, reduce tool wear in the working angles, prolong cutter life, shorten machining period, improve working (machining) efficiency, reduced workpiece deformation, improved machining accuracy.

1-main body wherein, the 2-bearing, the top body of 3-, the 4-spray nozzle, the 5-liquid inlet joint, the 6-gland, 7-knife bar main body, the 8-feed liquor is responsible for, 9-by-pass valve control, 10-threeway, 11-coolant hose, 12-workpiece, 13-lathe tool, 14-centre frame, 15-needle valve lubricating cup.
The specific embodiment
The filling of the cooling fluid of hydrojet live center and liquid-spraying type knife bar is adopted: feed liquor is responsible for 8 by by-pass valve control 9 controls, passes through threeway 10 then, is ejected into cutting surface through two coolant hoses 11 respectively.
When the processing sleeve workpiece, when processing excircles, the hydrojet live center is outside round table-like top body 3 rotations, and round platform bus maximum angle is 90 degree, and this angle contacts with interior Hole chamfering miter angle, and positioning accuracy is than higher.Liquid inlet joint 5 is used to insert inlet, and the gland 7 that is located at top body 3 round platform bottom surfaces is used for connecting this top body 3 and fastening bearing 2.
The hydrojet live center can play when the processing sleeve workpiece and reach the effect that inside and outside circle cools off simultaneously in the working angles.
When the processing sleeve workpiece, cool off the liquid-spraying type knife bar simultaneously for solving inside and outside circle during the processing endoporus, by knife bar tail end inlet, be that knife bar is made hollow shape, straight-through endoporus cutter head clamping or welding are with lathe tool 13 blades high slightly on an axis about 80mm position together.Can make that cooling fluid is directly injected to cutting surface, make the cutting zone temperature reduce greatly, and wash away the cutting chip, reduce the cutting chip preferably, to the friction and the scuffing of workpiece machined surface.Improve the machining accuracy of workpiece, can not unify the workpiece size of processing different apertures, can produce the different size model because of spraying knife bar.Centre frame 14 is used for supporting workpiece 12 among the figure, and needle valve lubricating cup 15 is used for lubricate, is prior art.
