Description
[technical field]
The utility model is the master jaw device that is used for tyre removing and replacing machine.
[background technology]
The existing master jaw device that is used for tyre removing and replacing machine generally all be by cylinder drive the claw holder assembly with the claw of symmetric offset spread on scratch diskette from inside to outside or motion from outside to inside, wheel hub is fixed in realization, but, and be connected with a seat upper plate employing single-point at master jaw because guide groove in scratch diskette does not add the guiding sliding panel.Like this, when cylinder promoted the master jaw motion, master jaw will drive a upper plate motion, but owing to adopt single-point to connect between them, if cylinder thrust is excessive suddenly in motion process, phenomenon, fluctuation of service will appear swinging up and down in the seat upper plate; Have again at guide groove not add the guiding sliding panel, when master jaw drives the motion of seat upper plate, also can occur swinging.
In order to solve the problem that prior art exists, the utility model has been made useful improvement.
[utility model content]
The utility model purpose is to have overcome deficiency of the prior art and a kind of simple in structure, master jaw device that the motion pulsation-free is used for tyre removing and replacing machine is provided.
In order to solve the technical matters of above-mentioned existence, the utility model adopts following technical proposal:
A kind of master jaw device that is used for tyre removing and replacing machine, include passive bearing, above bearing, be provided with the driving cylinder, on the driving cylinder, be provided with a scratch diskette, in scratch diskette, be provided with guide groove, be provided with guide piece at the guide groove upper surface, it is characterized in that on scratch diskette, being provided with and be used to connect the master jaw assembly that drives cylinder axis and transmit power, described master jaw assembly can slide between guide groove, the master jaw assembly includes a upper plate, guiding sliding panel and seat lower plate, described guiding sliding panel fixedly installs between present upper plate and the seat lower plate, and described guiding sliding panel is placed in the guide groove movably.
The master jaw device that is used for tyre removing and replacing machine as mentioned above is characterized in that captiveing joint with the seat lower plate with the seat upper plate respectively by screw in the two ends of described guiding sliding panel.
The aforesaid master jaw device that is used for tyre removing and replacing machine, it is characterized in that described master jaw assembly also includes and drives the master jaw that cylinder axis is connected, be provided with master jaw cap and claw successively above described seat upper plate, described seat lower plate and master jaw screw are connected and fixed; Described guiding sliding panel is that two screws are connected and fixed with the seat upper plate; Above bearing, be provided with a screw rod that passes master jaw, seat lower plate and seat upper plate and master jaw cap respectively.
The utility model compared with prior art has following advantage: because the utility model adds the guiding sliding panel in guide groove, there are described master jaw, guiding sliding panel to adopt be connected and fixed respectively at 2 again, promote to operate steadily in the motion process at cylinder like this with the seat upper plate; And simple in structure, use few part just can reach good effect.

Fig. 2 is that the utility model is installed in tyre removing and replacing machine part block diagram;
Fig. 3 is the block diagram that the utility model is installed in tyre removing and replacing machine.
[specific embodiment]
Below in conjunction with accompanying drawing the utility model is described in detail:
As shown in the figure, the deck device that is used for tyre removing and replacing machine, it is installed on the tyre removing and replacing machine, include passive bearing 1, above bearing 1, be provided with and drive cylinder 2, at the last scratch diskette 3 that is provided with, be provided with guide groove 31 for 3 li at scratch diskette, be provided with guide piece 5 at guide groove 31 upper surfaces, on scratch diskette 3, be provided with and be used to connect the master jaw assembly 4 that drives cylinder axis and transmit power, described master jaw assembly 4 can slide between guide groove 31, master jaw assembly 4 includes a upper plate 44, guiding sliding panel 47 and seat lower plate 42, described guiding sliding panel 47 fixedly installs between present upper plate 44 and the seat lower plate 42, described guiding sliding panel 47 is placed on 31 li of guide grooves movably, the two ends of described guiding sliding panel 47 by screw respectively with seat upper plate 44 and seat lower plate 42 between 2 captive joint because two some positions fix, so very steady when driving cylinder 2 and promote it and move.
Described master jaw assembly 4 also includes and drives the master jaw 41 that cylinder axis is connected, master jaw 41, and present upper plate 44 tops are provided with master jaw cap 45 and claw 46 successively, and described seat lower plate 42 is connected and fixed with master jaw 41 screws; Two screw retention that are connected to of described guiding sliding panel 47 and seat upper plate 44; Above bearing 1, be provided with a screw rod 46 that passes master jaw 41, seat lower plate 42 and seat upper plate 44 and master jaw cap 45 respectively.
