Utility model content
(1) technical problem that will solve
For the deficiency that prior art exists, the utility model provides a kind of can make the plastics back-up ring angle after cutting consistent, reduces labor strength, the plastics back-up ring angle cutting mechanism of increasing work efficiency.
(2) technical scheme
For achieving the above object, the utility model provides a kind of plastics back-up ring angle cutting mechanism, comprise backstay and cutting knife, locating slot and grooving, described grooving is crossing with described locating slot in an oblique angle, and the degree of depth of described grooving is greater than the degree of depth of described locating slot, and described locating slot width is identical with plastics back-up ring width to be processed, the width of described grooving is more than or equal to the thickness of cutting knife, and described cutting knife is placed in directly over described grooving.
Further, described backstay comprises construction section, and described construction section is cylindric, the plane at described locating slot place and the axial vertical of described construction section.
Further, described backstay is also provided with stops, described stops is positioned at the side of described locating slot and connects with described locating slot.
Further, described locating slot is cannelure.
Further, the external diameter diameter of described construction section is identical with plastics back-up ring inner ring diameter to be processed.
Further, described locating slot is arc-shaped.
(3) beneficial effect
The utility model plastics back-up ring angle cutting mechanism can make the plastics back-up ring angle after cutting consistent, reduces labor strength, increases work efficiency; Simultaneously on the basis of this instrument, after backstay and cutting are fixed, can mechanical automation be realized, increase work efficiency further.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing plastics back-up ring;
Fig. 2 is the structural representation under the utility model plastics back-up ring angle cutting mechanism using state;
The structural representation of backstay in Fig. 3 the utility model plastics back-up ring angle cutting mechanism.
In figure, 1 is backstay, and 2 is cutting knife, and 3 is plastics back-up ring, and 11 is grooving, and 12 is locating slot, and 13 is construction section, and 14 is stops, and 31 is angle.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
Fig. 1 is the structural representation of existing plastics back-up ring; Existing plastics back-up ring 3 generally needs to process angle 31.
Structure under a kind of plastics back-up ring angle cutting mechanism using state of the present utility model as shown in Figures 2 and 3, comprise backstay 1 and cutting knife 2, locating slot 12 and grooving 11, described grooving 11 is crossing with described locating slot 12 in an oblique angle, described locating slot 12 width is identical with plastics back-up ring 3 width to be processed, the width of described grooving 11 is more than or equal to the thickness of cutting knife 2, and described cutting knife 2 is placed in directly over described grooving 11.And the degree of depth of described grooving 11 is greater than the degree of depth of described locating slot 12, because plastics back-up ring 3 can be cut off completely when only in this way guarantee cutting knife 2 cuts.
The plastics back-up ring 3 that operationally will cut is placed in locating slot 12 place on backstay 1, and allows plastics back-up ring 3 free-falling, and then by cutting knife 2, the grooving 11 aimed on backstay 1 cuts downwards, completes the cutting work of plastics back-up ring 3.
As optimization, location when cutting for the ease of plastics back-up ring 3, described backstay 1 comprises construction section 13, and described construction section 13 is cylindric, the plane at described locating slot 12 place and the axial vertical of described construction section 13.Described backstay 1 is also provided with stops 14, and described stops 14 is positioned at the side of described locating slot 12 and connects with described locating slot 12.As long as like this plastics back-up ring 3 to cylindric medial movement, after plastics back-up ring 3 collide stops 14, just can ensure that plastics back-up ring 3 is in locating slot 12 place, now allow plastics back-up ring 3 free-falling that plastics back-up ring 3 just can be made to fall in locating slot 12.
Concrete backstay in the present embodiment 1 is made up of the cylinder that two bottom surface radiuses are different, and wherein construction section 13 is that cylinder that radius is less, and stops 14 is cylinders that radius is larger.
As optimization, in order to make plastics back-up ring 3 its cutting part potential energy when cutting be close to backstay 1, described locating slot 12 contacts with plastics back-up ring 3 and partly should be arc-shaped.Consider easy to process, in the utility model, locating slot 12 is annular, facilitates locating slot 12 to use lathe process.
Wherein, the external diameter diameter of described construction section 13 is identical with plastics back-up ring 3 inner ring diameter to be processed.This structure can further facilitate the location of plastics back-up ring 3.
The beneficial effects of the utility model: the plastics back-up ring angle after cutting can be made consistent, reduce labor strength, increase work efficiency; Simultaneously on the basis of this instrument, after backstay and cutting are fixed, can mechanical automation be realized, increase work efficiency further.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
