Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand following detailed description of the invention and only be not used in and limit the scope of the invention for the present invention is described.It should be noted that, word 'fornt', 'back', " left side ", " right side ", "up" and "down" that use is described below refer to the direction in accompanying drawing, and word " interior " and " outward " refer to respectively the direction towards or away from specific features geometric center.
As shown in the figure, a kind of bearing outer ring cracking device of the present invention, comprise pedestal 16, pressure handle 1, control block 4, movable block 7, limited block 11, described control block 4 is fixed on pedestal 16 both sides with limited block 11, movable block 7 is between control block 4 and limited block 11, pressure handle 1 is L-type, one end is suspended in limited block 11 tops, other end stationary cam 3, described cam 3 is arranged on that control block 4 is interior can be swung up and down by pressure handle 1, control block 4 one sides are provided with intercommunicating pore 5, movable block 7 one sides are provided with connecting axle 6 and stretch in intercommunicating pore 5, described connecting axle 6 and intercommunicating pore 5 matched in clearance, movable block 7 opposite sides are provided with pin-and-hole 8, between movable block 7 and limited block 11, be provided with machine table 12, machine table 12 is provided with bearing pin 9 near movable block 7 one sides and inserts in pin-and-hole 8, described bearing pin 9 and pin-and-hole 8 matched in clearance, described pin-and-hole 8 is not communicated with connecting axle 6, on bearing pin 9, cover has spring 10, in machine table 12, plane is higher than spring 10, movable block 7 opposite sides are the distance that cam 3 shrinks to the distance of machine table 12 1 sides.
Bearing outer ring cracking device of the present invention, object is that outer ring compressive deformation is ftractureed, operating procedure is: movable block 7 is put into in outer ring, in machine table 12 between limited block 11, pressure handle is to pressing down, cam rotates promotion connecting axle 6 and travels forward, connecting axle 6 links together with movable block 7, movable block 7 also travels forward, spring-compressed, movable block 7 makes outer ring stressed while travelling forward, outer ring limited block 11 below stops outer ring to be moved backward simultaneously, outer ring is because of front and back pressurized strain cracking, cracking place stress is concentrated and is ftractureed in line, the present invention is simple in structure, utilize the swing promotion movable block last item of cam to hold, can easily bearing outer ring be crushed, other parts of the inside are taken out, speed is fast, efficiency is high, safe ready.
Generally, connecting axle 6 welds together with movable block 7, but the bearing designation difference of operation, and bearing size is different, for cost-saving, a tractor serves several purposes, the present invention is provided with regulating tank 13 above described movable block 7, and movable block 7 is connected with connecting axle 6 bolts, the direction of described regulating tank 13 is the direction of motion of movable block, have regulating tank, the position of movable block 13 just can be adjusted, and adapts to Multiple Type bearing and uses.
General bearing is circular, the present invention is placed on bearing in machine table 12, movable block 7 travels forward, outer ring limited block 11 below stops outer ring to be moved backward simultaneously, for preventing that bearing from sliding to side, the present invention is by described movable block 7, the contact-making surface V-shaped 2 of limited block 11 and bearing, bearing is stuck in relative V-type groove, can not slide to side, because long-time last item holds, movable block 7 of the present invention can be out of shape and cause fixture to be scrapped with limited block 11 opposite faces, therefore by movable block 7 and limited block 11 opposite face Quenching Treatment, its hardness reaches HRC55, it is indeformable when last item holds, long service life.
Because plane in machine table 12 is higher than spring 10, in the time that last item holds, movable block 7 slowly forward, in the time moving to machine table 12 1 side, the length that now cam 3 stretches out is the longest, and machine table 12 sides block movable block, and now the distance between movable block 7 and limited block 11 is than the little 2-4mm of bearing 15 race diameter, bearing outer ring strain cracking, when after bearing outer ring cracking, pressure handle 1 to be pulled on, cam is regained, movable block 7 resilience under the effect of spring, unclamp bearing, prepare next work, operating rate of the present invention is fast, efficiency is high, safe ready.
The disclosed technological means of the present invention program is not limited only to the disclosed technological means of above-mentioned embodiment, also comprises the technical scheme being made up of above technical characterictic.
