The polishing disk locking device of the pneumatic polishing machine comprises an eccentric wheel, a bearing used to be installed inside the eccentric wheel, a gasket, an elastic check ring for holes, a fixing plate, a bearing seat and a counter weight, wherein the bearing seat is provided with a positioning hole, the fixing plate is fixed on the eccentric wheel with screws through the counter weight, can shift and move with the counter weight as a supporting point, and is annular, and an inner ring of the fixing plate is provided with a fixing pin.
Description
Technical field
The utility model belongs to the pneumatic tool field, refers to especially a kind of polishing disk locking device of pneumatic polisher.
Background technology
The polishing disk of polishing machine is to need the often parts of replacing, when carrying out different operations, needs need to change the polishing disk of different model, the replacing of polishing disk is to change with the securing member on the eccentric wheel by polishing disk in the existing technology, this substitute mode can't be finished by hand, need tool using just can finish the replacing of polishing disk, this is very inconvenient during operation.
The inventor proposes one and improves technical scheme according to the familiar lacunas of the polishing disk of the polishing machine of existing use, and this technical scheme has overcome existing polishing machine needs tool using when changing polishing disk weak point fully, can change easily by hand polishing disk.
The utility model content
The purpose of this utility model is to propose a technical scheme, and this technical scheme can adopt the manual polishing disk of changing, and needing to have avoided the loaded down with trivial details step of tool changing polishing disk.
The utility model is achieved through the following technical solutions:
A kind of polishing disk locking device of pneumatic polisher includes an eccentric wheel, and one is used for being installed on the bearing in the eccentric wheel, pad, circlip for hole, fixed head, bearing block, balancing weight; Described bearing block has a locating hole, and described bearing block inserts in the eccentric bearing; Described fixed head is screwed on eccentric wheel by balancing weight, and described fixed head can be offset take balancing weight as fulcrum and move; Described fixed head is its inner ring of annular a steady pin, steady pin can be inserted or dial-out in the locating hole of bearing inquiry by mobile fixed head.
As further improvement, described bearing block can be structure as a whole with polishing disk.
The beneficial effects of the utility model are:
Pass through the technical solution of the utility model, when needs are changed polishing disk, only need to be by moving fixed head, the steady pin of fixed head inner ring is shifted out in the locating hole of bearing block, the polishing disk that just can take down polishing disk then will need to change connects the rear centre that is inserted into capacity eccentric bearing by the annulus in the middle of the fixed head with bearing block, move the fixed head pin that is fixed and be inserted into the replacing of just having finished polishing disk in the locating hole of bearing block, all processes does not need to use any instrument auxiliary.

The specific embodiment
Describe concrete technical scheme of the present utility model in detail below in conjunction with accompanying drawing, specific embodiment of the utility model only is exemplary, can only be used for explaining the utility model and can not be interpreted as to be to restriction of the present utility model.
Shown in 1, the utility model is achieved through the following technical solutions with reference to the accompanying drawings.
A kind of polishing disk locking device of pneumatic polisher includes an eccentric wheel 43, and is used for being installed on the interior bearing 47 of eccentric wheel, pad (46,48), and circlip for hole 49,, fixed head 50, bearing block 51, balancing weight 53; Described bearing block 51 has a locating hole, and described bearing block 51 inserts in the eccentric bearing 47; Described fixed head 50 is fixed on the eccentric wheel 42 by balancing weight 53 usefulness screws 54, and described fixed head 50 can be offset take balancing weight 53 as fulcrum and move; Described fixed head 50 is its inner ring of annular a steady pin, steady pin can be inserted or dial-out in the locating hole of bearing inquiry by mobile fixed head.
In the present embodiment, the polishing disk 55 that uses is prior art, does not need to improve especially, and there is internal thread in described bearing block axle center, polishing disk with holding screw with the screw-internal thread fit of bearing block; Eccentric wheel has a screw near a side of polishing disk, eccentric shaft bearing is packed in the eccentric wheel, and block with circlip for hole after fixing with pad and screw again; With fixed head, balancing weight pad, balancing weight are screwed on the eccentric wheel, and described screw matches for fixedly fixed head and balancing weight with eccentric screw; Described fixed head can manually move take the screw of fixed head and balancing weight as fulcrum; By being inserted in the eccentric bearing behind the ring in the fixed head, mobile fixed head is inserted into the steady pin of fixed head inner ring in the locating hole on the bearing block, finishes the installment work of polishing disk with bearing block part.
When needs are pulled down polishing disk, move fixed head, transfer to and then transfer to polishing disk just to finish dismantlement work from the locating hole of bearing block the steady pin of fixed head inner ring.
In the technical solution of the utility model, bearing block is split-type structural with polishing disk, in other embodiments, bearing block is structure as a whole with polishing disk, in order to improve the adaptability of polishing machine, preferably bearing block is Split type structure with polishing disk, and existing like this polishing disk just can be applicable to the technical solution of the utility model and not need independent manufacturing.
The above only is the specific descriptions to technical solutions of the utility model, and those skilled in the art can improve according to the technical program certainly, and these improvement should be considered in the protection domain of the present utility model.
