Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe wholely.
The invention provides a kind of tire grinding apparatus, structure as shown in Figure 1, this equipment can be adjusted according to the specification of tire
Joint copying apparatus fits with master plate, thus quickly realizes the conversion of different size tire polishing.
Tire grinding apparatus as shown in Figure 1, including frame 1 and base 2, frame 1 is provided with liter tire part, a tire clamping
Part and tyre rotation drive part, base 2 is provided with supporting plate part and polishing part.Rise tire part to include being fixed on frame 1
On hydraulic cylinder 1, and the connecting rod 1 that is attached thereto and rise tire pedal 5.Tire clamping part includes being arranged in frame 1
Two chucks 6 that left and right is relative, one chuck 6 connects hydraulic cylinder 27.Tyre rotation drive part includes being fixed in frame 1
The hydraulic cylinder 38 of side, and the connecting rod 29 that is attached thereto and drive cylinder 10, drive cylinder 10 to connect and drive motor 1.
Referring to figs. 2 and 3, supporting plate part includes bottom plate 12, middle supporting plate 13 and mounting plate 14.Longitudinally it is provided with on base 2
Two feed rods 1, bottom plate 12 is positioned on feed rod 1, and by leading screw 1 and shaft coupling 1 and driving motor 2 18
Connecting, bottom plate 12 respect thereto 2 is longitudinally movable.Being transversely provided with two feed rods 2 19 on bottom plate 12, middle supporting plate 13 is positioned at
On feed rod 2 19, and it is connected with driving motor 3 22 by leading screw 2 20 and shaft coupling 2 21, the middle relative bottom plate 12 of supporting plate 13
Can transverse shifting.Longitudinally being provided with two feed rods 3 23 on middle supporting plate 13, mounting plate 14 is positioned on feed rod 3 23, and is filled by tension
Putting (not shown) to be connected with middle supporting plate 13, the relatively middle supporting plate 13 of mounting plate 14 is longitudinally movable.
Polishing part includes the grinding head 24 being fixed on mounting plate 14 front end, and grinding head 24 is relative with tire clamping part；
Mounting plate 14 end is fixed with copying apparatus, and bottom plate 12 is vertically disposed with three pieces of master plates 25, and master plate 25 to
Under become big successively, copying apparatus becomes placed against with arbitrary master plate 25.
As shown in Figure 4, copying apparatus includes gear 26 and the tooth bar 27 being vertically arranged on mounting plate 14, tooth bar 27 upper end
Being provided with pattern roller 28, gear 26 connects has rocking handle 29, pattern roller 28 to become placed against with arbitrary master plate 25.
It is provided with the hydraulic pressure that pattern roller 28 and master plate 25 can be made to be adjacent to all the time between mounting plate 14 and middle supporting plate 13 to draw
Tight device (not shown).
The specific works process of this equipment is as follows:
The tire meeting polishing condition is delivered on liter tire pedal 5, after it is stable, hydraulic cylinder 1 company of pushing down on
Bar 1, due to leverage, tire is increased to specified altitude assignment under liter tire pedal 5 promotes therewith；Subsequently, hydraulic cylinder 27
Drive one of them chuck 6 to move, and make tire be clamped by both sides chuck 6；Hydraulic cylinder 38 carries under hydraulic tensioning power effect
Dynamic driving cylinder 10 is tightly close to tire and by driving motor 1 to drive it to rotate；Bottom plate 12 is driving motor 2 18 work
Realizing length feed motion under with, middle supporting plate 13 realizes in-movement under driving motor 3 22 effect；Mounting plate 14 leads to
Cross the interaction of pattern roller 28 and master plate 25 simulate the camber line of master plate 25 require and drive grinding head 24 realize into
Giving motion, grinding head 24 cuts grinding tyres under polishing motor 30 drives, and polishing head-shield 31 reclaims polishing chip；Polishing
Cheng Zhong, by fluid-pressure straining device so that pattern roller 28 is adjacent to all the time with master plate 25.Next is carried out when completing polishing
During specification tyre polishing, shake rocking handle 29 makes pattern roller 28 fit with corresponding master plate 25 the most again to polish.
The tire grinding apparatus of the present invention can carry out renovation polishing by brand-new copying apparatus tire waste and old to different model,
Only need to shake rocking handle 29 and fix just can be to the tyre surface of multiple different types of tyres in addition ground, simplification is polished and is grasped
Make flow process.In gear rack arrangement, it is increased to certain altitude with the rotation tooth bar of rocking handle 29, such that it is able to good leans on from different
Template 25 matches, because pinion and rack is difficult to self-locking, so big master plate 25 is put into bottom, the most ingenious
The introducing avoiding rack-and-pinion self-locking device.Pattern roller 28 is pulled to and phase by fluid-pressure straining device after reaching a certain height
Should fit tightly by master plate 25 highly, and following bulk master plate 25 serves good supporting role and avoids pattern roller
28 glide, as long as and when pattern roller 28 needs to move downward, fluid-pressure straining device is unclamped, can easy adjustment to the lowest by one
The height of level, thus enormously simplify the complexity of device, makes overall machine run relatively reliable.
The profiling tire sanding apparatus of the present invention includes grinding head drive part and polishing head-shield 31, and grinding head 24 is in polishing
Rotating under the drive of motor 30 and belt 32, polish tyre tread part, whole grinding head 24 is by an opening
Polishing head-shield 31 surround, opening, to tire direction, so comprehensive can siphon away the dust that drops of polishing when polishing.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses the present invention.
Multiple amendment to these embodiments will be apparent from for those skilled in the art, as defined herein
General Principle can realize without departing from the spirit or scope of the present invention in other embodiments.Therefore, the present invention
It is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein and features of novelty phase one
The widest scope caused.
