Abstract
The utility model provides a kind of glass-cutting break bar of novel in structural design, and the cutter hub of mounting hole is offered including middle part；The inner wall of the mounting hole is equipped with several slot bands, and the slot band is arranged along the axial direction of cutter hub, and slot band runs through the end of inner wall of the hole installing, several slot bands are arranged with the axisymmetrical of cutter hub.
Description
Technical field
The utility model relates to a kind of glass-cutting break bars.
Background technique
Glass-cutting break bar is the specialized guide wheel for being cut to glass, and shape is rounded, and circumferential edge is equipped with knife
Sword, middle part are equipped with mounting hole, are mounted on knife rest by installing bearing, in the glass cutting equipment of Digital Control, are led
For wheel in cutting, knife rest receives the pressure of square shaft, promotes break bar to roll on glass and achievees the purpose that cutting, but actual
It was found that the inner wall of the hole installing direct friction of installation axle and break bar, leads to mounting hole aperture after prolonged friction in
Become larger, error will occur in break bar run trace after mounting hole aperture becomes larger, secondly, friction easily leads to the use of break bar and installation axle
Service life reduction；Furthermore break bar is mounted on knife rest by installation axle, due to not having corresponding limit in the installation axle of break bar two sides
Position device causes break bar the problem of moving axially along installation axle easily occur, and the appearance of this problem also results in break bar run trace
Error to occur.
Summary of the invention
The purpose of the utility model is to overcome the deficiencies in the prior art, adapt to reality and need, and provide a kind of structure design
Novel glass-cutting break bar.
In order to realize the purpose of this utility model, the technology employed by the present utility model is
A kind of glass-cutting break bar is designed, the cutter hub of mounting hole is offered including middle part；It is set on the inner wall of the mounting hole
Have several slot bands, the slot band is arranged along the axial direction of cutter hub, and slot band runs through the end of inner wall of the hole installing, several slot bands with
The axisymmetrical of cutter hub is arranged.
The end of the slot band is 1.0mm-2.00mm.
Further include the installation axle of penetrating mounting holes, is set in installation axle there are two spaced annular slot, work as installation axle
When being mounted in mounting hole, two annular slots are located at the two sidewalls of cutter hub, are respectively equipped with card in two annular slots
Spring, cutter hub are located between two circlips.
Oiling road is equipped in the installation axle, the import in oiling road is located at the end of installation axle one end, the outlet in oiling road
The middle part of installation axle is set, and when installation axle is mounted in mounting hole, the outlet in oiling road is located at the medium position of mounting hole
Place.
The utility model has the beneficial effects that:
It is the design its novel in structural design, simple, rubbing between installation axle and mounting hole can be reduced first in use
Power is wiped, the problem of reducing because of friction bring break bar run trace deviation, service life is further decreased, meanwhile, pass through
The effect of circlip can limit the break bar of installation on the mounting shaft, avoid the problem that break bar moves axially.
Detailed description of the invention
Fig. 1 is the break bar the schematic diagram of the section structure of the utility model；
Fig. 2 is the break bar schematic view of the front view of the utility model；
Fig. 3 is the schematic diagram of the section structure of the break bar installation of the utility model on the mounting shaft.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples:
Embodiment 1: a kind of glass-cutting break bar, referring to Fig. 1 to Fig. 3；
It includes the cutter hub 1 that middle part offers mounting hole 2；The design is equipped with several on the inner wall of the mounting hole 2
Slot band 3, the slot band 3 is arranged along the axial direction of cutter hub, and the end of 33 penetrating mounting holes inner wall of slot band, several slot bands are with cutter hub
Axisymmetrical setting, the contact area of inner wall of the hole installing and installation axle can be reduced by this slot band, this design can reduce peace
The frictional force between axis and mounting hole is filled, and then improves the service life of break bar.
Further, the end of the slot band is 1.0mm-2.00mm.
The slot band of the design can also be used as in use oil storage tank use, when as oil storage tank in use, each slot band
It can be closed groove, that is, the both ends of slot band are placed on the inner wall of mounting hole the not end of penetrating mounting holes inner wall.
Further, it further includes the installation axle 4 of penetrating mounting holes 2, is set in installation axle 4 there are two spaced annular
Card slot 5, when installation axle 4 is mounted in mounting hole 2, two annular slots 5 are located at the two sidewalls of cutter hub, two annulars
Circlip 6 is respectively equipped in card slot 5, cutter hub 4 is located between two circlips 6, limits by two circlips to conductor, avoid leading
The axial movement of body on the mounting shaft, solves the problems, such as that trajector deviation occurs during exercise in cutter hub.
Further, the design is equipped with oiling road 7 also in the installation axle 4, and the import in oiling road 7 is located at installation axle one
The end at end, the middle part of installation axle is arranged in the outlet in oiling road 7, and when installation axle is mounted in mounting hole, oiling road goes out
Mouth is located at the medium position of mounting hole, lubricating oil can be injected into the oiling road 7 by oiling road 7, and then will by oiling road 7
Lubricating oil is sent between installation axle and mounting hole and in slot band, and then reduces frictional force between the two, is improved cutter hub and is being used
In precision and service life.
To sum up, its novel in structural design of the design, simple, can reduce between installation axle and mounting hole first in use
Frictional force, further decrease because friction bring break bar run trace deviation, service life reduce the problem of, meanwhile, pass through
The effect of circlip can limit the break bar of installation on the mounting shaft, avoid the problem that break bar moves axially, finally
Improve cutter hub precision and service life in use.
What the embodiments of the present invention were announced is preferred embodiment, and however, it is not limited to this, the common skill of this field
Art personnel understand the spirit of the utility model easily according to above-described embodiment, and make different amplification and variation, but as long as
The spirit of the utility model is not departed from, it is all within the protection scope of the present utility model.
