Abstract
A movable flat-top center of roll grinder relates to an auxiliary accessory device of machine tools, and is characterized in that the middle portion of a tapered center is provided with an annular groove, and is further provided with a flat-top device, the flat-top device comprises an inner platform sleeve provided with a frustum hole, a radial bearing sleeved on the excircle of a step cylinder onthe middle portion of the inner platform sleeve, a lower cover behind a radial bearing excircle sleeve, an axial bearing sleeved with the excircle of the step cylinder of the front end of the inner platform sleeve, an upper cover sleeved with the other end of the axial bearing, and a flat-top platform behind the other lateral sleeve of the upper cover, wherein the upper and the lower covers are connected through a countersunk bolt, the flat-top platform is connected with the upper cover through the countersunk bolt, and two screwed holes are arranged on cylindrical holes on the rear end of acentral frustum hole of the inner platform sleeve, when the inner platform sleeve is sleeved into a tapered center and is jointed with the center, locating screw bolts are screwed into the two screwedholes, cylinders on the front ends of the two locating screw bolts just extend into the annular groove arranged on the tapered center, thereby realizing the fixed connection between the flat-top center and the tapered center. The movable flat-top center has the advantages that only a movable flat-top device needs to be directly sleeved on without taking off the tapered center, the structure is reasonable, and the disassembly is simplified.
Description
Technical field:
The utility model lathe auxiliary accessory device.
Background technology:
Putting on the shelf of roll grinder is after the lifting roll makes roll two ends central aperture headstock and tailstock cone centre earlier, to adjust centre frame the roll axial line is put in place at present, and then must take out cone centre changes the flat-top point, and roll just can enter grinding process.
The cone centre structure is the latter half of frustum that is, corresponding to the frustum hole on headstock, the tailstock, the cone centre middle part is a cylinder, first half is a bullet, the flat-top point is that with the cone centre difference first half is a cylinder, make flat-top point and roll axial end realize plane contact, the roll two ends are all changed the flat-top pinnacle and roll axial end assurance roll axial limiting.And when changing centre operation, the low influence production of work efficiency is comparatively required great effort in the big taking-up of frictional force because the conical surface in the frustum hole on cone centre and headstock, the tailstock is fitted closely.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned defective, and a kind of movable flat-top point of roll grinder is provided.
Scheme of the present utility model is: offer annular groove at the cone centre middle part, be provided with the flat-top device in addition, the flat-top device is by the interior platform cover with the frustum hole, the journal bearing of fit on the interior platform cover middle bench cylinder cylindrical, lower cover behind the journal bearing cylindrical cover, the cod of cylinder cylindrical fit on the interior platform cover front end step, the loam cake of cod other end fit, flat-top platform behind the loam cake opposite side cover is formed, on, connect with dormant bolt between the lower cover, be connected with dormant bolt between flat-top platform and the loam cake, it is cylindrical hole that interior platform overlaps rear end, central frustum hole, cylindrical hole is provided with two screwed holes up and down, when interior platform overlaps that central frustum borehole jack is gone into cone centre and when implement fitting, platform was when putting two screwed holes in positioning stud was screwed into, and two bolt front end cylinders just stretch into fixedlying connected of the annular groove realization activity flat-top point offered on the cone centre and cone centre.
Advantage of the present utility model is: needn't take off cone centre, realize roll installation flat-top as long as directly put movable flat-top device, rational in infrastructure, dismounting is simplified.
Description of drawings:
Accompanying drawing is the utility model structural representation.
The specific embodiment:
Structure of the present utility model comprises cone centre (5), it is characterized in that offering annular groove at cone centre (5) middle part, be provided with the flat-top device in addition, the flat-top device is by the interior platform cover (1) with the frustum hole, the journal bearing of fit on interior platform cover (1) the middle bench cylinder cylindrical, lower cover (2) behind the journal bearing cylindrical cover, the cod of cylinder cylindrical fit on interior platform cover (1) the front end step, the loam cake (3) of cod other end fit, flat-top platform (4) behind loam cake (3) the opposite side cover is formed, on, lower cover connects with dormant bolt between (2), be connected with dormant bolt between flat-top platform (4) and the loam cake (3), rear end, interior platform cover (1) central frustum hole is a cylindrical hole, cylindrical hole is provided with two screwed holes up and down, when the central frustum borehole jack of interior platform cover (1) is gone into cone centre (5) and is implemented to fit, in positioning stud is screwed into during last two screwed holes of platform cover (1), two bolt front end cylinders just stretch into the annular groove realization activity flat-top of offering on the cone centre (5) sharp with the fixedlying connected of cone centre (5).
During operation, after the roll lifting puts in place, centre frame adjustment roll puts in place, after mobile lathe bed is reserved installing space, movable flat-top point is inserted in cone centre (5) to be fixed with bolt, mobile again lathe bed makes roll mandrel fit to the flat-top platform (4) of both ends of the surface and two flat-top points and just can enter next process.
Flat-top platform (4) material is made by bakelite or nylon flexible material.
Claims (1)
