Abstract
The utility model discloses a replacement and demounting device special for bearings in bearing boxes in wire cutting machines. The replacement and demounting device comprises a base plate. A plurality of vertical posts are disposed on the base plate. A top plate is fixedly supported on the top of every vertical post. The top plate is provided with a round hole; the diameter of the round hole is slightly larger than the bore of a bearing inner sleeve; a hydraulic cylinder is arranged on the base plate right below the round hole; the diameter of a piston rod of the hydraulic cylinder is smaller than the bore of a bearing inner sleeve. The replacement and demounting device has the advantages that the defects of the prior art are overcome, a shaft core is evenly stressed during bearing demounting and is protected from damage, post-mounting stability of a bearing box is better guaranteed, and operation is simple.
Description
Technical field
The utility model belongs to solar energy silicon rod multi-wire saw technical field, is specifically related to a kind of line cutting machine replacing bearing box bearing special demounting device.
Background technology
Bearing housing is the critical function parts on line cutting machine, and because production task is large, utilization rate of equipment and installations is high, and the bearing in bearing housing often needs to change.But, because the back-to-back heat of a plurality of bearings on the axle core is installed, in changing the bearing process, very easily because unbalance stress causes the damage to the axle core, bearing housing stability is reduced.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of line cutting machine replacing bearing box bearing special demounting device, and when the dismounting bearing, axle core uniform stressed, to zero damage of axle core, guarantee the stability after bearing housing is installed better.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of line cutting machine replacing bearing box bearing special demounting device, comprise bedplate, and bedplate is provided with many root posts, and the top fixed support of column has a top board; Have a circular hole on top board, the diameter of circular hole is more bigger than the aperture of bearing inner sleeve, is provided with a hydraulic cylinder on the bedplate under circular hole, and the diameter of the piston rod of hydraulic cylinder is less than the aperture of bearing inner sleeve.
Wherein, described column is three or four, is equilateral triangle or square profile.
Wherein, the piston rod of described hydraulic cylinder is provided with a cylindrical fore-set, and the diameter of fore-set is greater than the aperture of bearing inner sleeve and is less than the diameter of circular hole.
Wherein, be provided with one to three cushion block between the bottom of described hydraulic cylinder and bedplate.
Wherein, described device also comprises a pair of for being fastened on the clamping plate of the semicircle annular on bearing inner sleeve, and the diameter of clamping plate is equal to or slightly less than the aperture of bearing inner sleeve.
The beneficial effect that adopts technique scheme to produce is: the utility model has overcome above defect, makes axle core uniform stressed when the dismounting bearing, to zero damage of axle core, guarantees better the stability after bearing housing is installed.The utility model is easy and simple to handle, in use can people's independent operation, save labor, and high efficiency.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1, top board, 2, the bedplate steel plate, 3, column, 4, hydraulic cylinder, 5, cushion block, 6, bearing inner sleeve, 7, bearing outside, 8, fore-set, 9, mandrel.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, the utility model is a kind of line cutting machine replacing bearing box bearing special demounting device, comprises bedplate 2, and bedplate 2 is provided with many root posts 3, and the top fixed support of column 3 has a top board 1; Column 3 is three or four, is equilateral triangle or square profile, so that firm being fixed on column 3 of top board 1, and top board 1 and bedplate 2 keeping parallelisms; Have a circular hole on top board 1, the diameter of circular hole is more bigger than the aperture of bearing inner sleeve 6, is provided with a hydraulic cylinder 8 on the bedplate 2 under circular hole, and the diameter of the piston rod of hydraulic cylinder 8 is less than the aperture of bearing inner sleeve 6; Be provided with one to three cushion block 5 between the bottom of hydraulic cylinder 4 and bedplate 2, enough height that hydraulic cylinder 4 can be supported; The piston rod of hydraulic cylinder 4 is provided with a cylindrical fore-set 8, and the diameter of fore-set 8 is greater than the aperture of bearing inner sleeve 6 and is less than the diameter of circular hole, when fore-set 8 falls short of for the piston rod of hydraulic cylinder 4; The utility model also comprises a pair of for being fastened on the clamping plate of the semicircle annular on bearing inner sleeve 6, and the diameter of clamping plate is equal to or slightly less than the aperture of bearing inner sleeve 6.
Using method:
During operation, band is had been friends in the past to axle core 9 top of bearing to the circular hole place of fore-set 8, following hydraulic cylinder 4 pressurizations, move upward axle core 9, and bearing outside 7 and ball are come off; Now, only remain bearing inner sleeve 6 on axle core 9 and do not unload, a pair of semicircular clamping plate are fastened to above bearing inner sleeve 6 and screw down, more once get final product with hydraulic cylinder 4 tops.
