It is completely obscured, prevent shot and grit from entering in rear axle housing.
Preferably, the cover board is provided with convex block on the end face of locating slot, and the material of the convex block is also polyurethane
And be made of one piece with cover board, offer punched out on the convex block, the punched out for penetrate external club and then
The separation cover plate from mounting hole.
Through the above technical solutions, since magnet holds cover board and rear axle housing, thus be difficult to after the completion of ball blast directly from
External club after adding convex block and punched out, is inserted into punched out, you can by separation cover plate in mounting hole by club easily
The suction of magnet is overcome to carry away cover board from mounting hole.
Preferably, the quantity of the convex block is two, and two convex blocks are located remotely from the position of cover plate central respectively, two
The axis collinear of a punched out.
Through the above technical solutions, then external club also cross two punched out, can lift one end of club, then
Club drives one end of cover board to lift easily by lever principle, and the other end completion for then lifting club is totally separated, and is made
The separation of cover board and rear axle housing is more effortless.
Preferably, the cover board is provided with several steel bars on the end face of locating slot, and several steel bars are used to strengthen
The overall stiffness of cover board.
Through the above technical solutions, since cover board made of polyurethane has flexibility, may occur in use curved
Bent deformation effect uses, and adds after steel bar and strengthens the overall stiffness of cover board, and cover board is not easy flexural deformation in use.
Preferably, several steel bars intersect to form cross.
Through the above technical solutions, the structure of steel bar is more firm, cover board is made to have the strong of resistance to deformation from all directions
Degree.
In conclusion the utility model having the beneficial effect that in contrast to the prior art：This rear axle housing shotblasting protection dress
The service life of cover board can be extended by putting, and save cost, and be firmly installed, positioning accuracy height.

Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
This specific embodiment is only explanation to the utility model, is not the limitation to the utility model, ability
Field technique personnel can as needed make the present embodiment the modification of no creative contribution after this specification is read, but
As long as it is all protected in the right of the utility model be subject to Patent Law.
As depicted in figs. 1 and 2, a kind of rear axle housing shotblasting protective device, including circular cover board 2, one end of cover board 2
It is wholely set on face there are two convex block 3, two steel bars 4 is fixed on the other end of cover board 2.
Cover board 2 is by polyurethane into polyurethane material possesses higher intensity and good wear-resisting property, and possesses certain
Elasticity, play the role of shock-absorbing under the shock of shot.The energy during by frequent ball blast of cover board 2 made of polyurethane
Outstanding tolerance performance is kept, service life is much larger than steel plate.
As shown in Figures 2 and 3, the diameter of cover board 2 is slightly larger than the diameter of mounting hole 11, and the side wall of cover board 2 circumferentially opens up
There is locating slot 21, the end face that locating slot 21 is close to 4 place of steel bar opens up.Locating slot 21 is annular groove, what locating slot 21 was formed
The diameter on cylindrical surface is identical with the aperture of mounting hole 11.It is circumferentially spaced on the annular surface of locating slot 21 to offer multiple mounting holes
211, multiple mounting holes 211 are centrosymmetric distribution compared with the axis of cover board 2.It corresponds and fixes in each mounting hole 211
There is magnet 5, shape and the mounting hole 211 of magnet 5 match, and the thickness of magnet 5 is identical with the hole depth of mounting hole 211.Each magnet 5
It is fixed by glue and cover board 2, annular surface of each magnet 5 towards the end face of steel bar 4 with locating slot 21 flushes.
As shown in figures 1 and 3, the material of two convex blocks 3 is also made of one piece for polyurethane and with cover board 2.Two convex
Block 3 is located remotely from the position at 2 center of cover board respectively, and two convex blocks 3 are distributed compared with the central symmetry of cover board 2.Two convex blocks 3
On offer punched out 31, the axis collinear of two punched out 31 and parallel to the plate face of cover board 2.Punched out 31 is used to penetrate
External club, and then the easily separation cover plate 2 from mounting hole 11 improve production efficiency.
Two steel bars 4 are by the axis of cover board 2, and two steel bars 4 intersect to form cross.Two steel bars 4 add
The overall stiffness of cover board 2, cover board 2 are not easy flexural deformation in use.
In use, locating slot 21 and the oral area of mounting hole 11 are offseted, cover board 2 is made to cover mounting hole 11.Due to each magnetic
Iron 5 is fully located inside cover board 2, so the annular surface of locating slot 21 can be completely obscured by mounting hole 11, prevents shot and grit
Into inside rear axle housing, and positioning accuracy is higher.Then rear axle housing is put into together with this protective device in shot-blasting machine and carries out ball blast
Process, during ball blast, since shot from all directions impacts rear axle housing and cover board 2, thus cover board 2 be subject to from shot
It is smaller with joint efforts, and cover board 2 is inhaled by magnet 5 on rear axle housing, ball blast process cover plate 2 is not easily to fall off or shifts.
The above is only the exemplary embodiment of the utility model, the protection model rather than limited the present invention
It encloses, the scope of protection of the utility model is determined by appended claim.
