Abstract
A three-jaw wearless rim type tire detacher comprises a circular tray; the structure of the utility model is that one end of a cylinder body is connected with the circular tray; the other end of the cylinder body is connected with a hanging rack and with one end of a main connecting rod through a piston shaft; the other end of the main connecting rod is connected with a triangle turnplate; another two angles of the triangle turnplate are provided with two connecting rods; the main connecting rod and the other ends of the two connecting rods are connected with a jaw which is arranged in an inner limit of a slideway. The product overcomes the disadvantages of loosening easily of a four-jaw type, improves equipment characteristic, simplifies the mechanical structure of equipment, reduces manufacturing hardness and expenses, avoids clipping the rim loosely and damaging the rim when detaching the tire and is safe, reliable, convenient in use and easy in popularization.
Description
The utility model relates to a kind of rim type tyre removing and replacing machine, and particularly a kind of three claws can't harm the rim type tyre removing and replacing machine, belongs to self-propelled vehicle manufacturing, the maintenance industry dismounting automatic field to tire.
Automobile manufacturing of the prior art, the employed tyre removing and replacing machine of maintenance industry when the dismounting tire, adopt the mode of operation of Pneumatic four claw chucking substantially to the chucking of wheel rim.The card power of four claws is to be propulsion source by pressurized air, makes cylinder axis do linear reciprocating motion, drives rotating disk, connecting rod is passed to power on the spacing claw of slideway at last.Four claws are distributed on the disk by 90 °, and path of motion is all pointed to the center of circle.When using claw move reciprocatingly can finish to the chucking of wheel rim with unclamp.During chucking, utilize manipulator that wheel rim is separated with tire or assemble.The four-jaw type tyre removing and replacing machine is that four pawls are divided into two groups, promptly initiatively and driven two groups, and two groups and the equidistant and vertical distribution in the center of circle.Its dynamic analysis shows: when claw obtains propulsive effort, four claws will shrink (or leaving the center of circle) to the center of circle simultaneously, when claw chucking wheel rim, even if accuracy of manufacture is high again, because cumulative limit institute extremely, a pair of claw of actv. and driven a pair of claw are as long as there is one group power to impose on the wheel rim earlier, the power of another group imposes on and will be in a kind of void on the wheel rim and touch state so, and the power that is to say just can not given four claws by 1/4th proportional distribution.Above-mentioned showing, there are three problems in " four claws " formula in the process of making, using: one, improve accuracy of manufacture and also can't resolve the synchronous problem of four paws, and increased manufacturing expense; Its two, by the wheel rim that is installed owing to only be subjected to the effect of two claws yielding; Its three because two claw work friction are little, external rotational force causes wheel rim and claw to slide and the damage wheel rim during dismounting tire.
The purpose of this utility model is the deficiency at existing four claw technology, and develops, designed the harmless rim type tyre removing and replacing machine of rational three claws of structure.
For achieving the above object, the utility model adopts following technical scheme: three claws can't harm the rim type tyre removing and replacing machine, its three claw be by 120 ° angle distribution on a disk, path of motion is also pointed to the center of circle, wherein a claw is initiatively, two claws are driven in addition, all in three pull bars and triangle rotating disk interlock.Rotate a certain angle when propulsive effort makes three angle rotating disks, the pulling of three connecting rods is being pointed to through three spacing claws of slideway on the track in the center of circle and is being done straight reciprocating motion, finish to the chucking of wheel rim with unclamp.Three claws can't harm the rim type tyre removing and replacing machine, comprise disk (6), and its concrete structure is: an end of cylinder block (7) is connected with disk (6); The other end is connected with an end of hanger (4), main connecting rod (3) by the axis of the piston (5), the other end of main connecting rod (3) is connected with triangle rotating disk (9), the triangle rotating disk is provided with two connecting rods (8) in two angles in addition, main connecting rod (3) is connected with claw (2) with the other end of two connecting rods (8), and claw (2) is located in the slideway (1) spacing.
Characteristics of the present utility model are: 1, overcome the shortcoming of the physical construction of " four claws " formula, reached the purpose that improves equipment performance and quality; 2, simplify the plant machinery structure, reduced manufacture difficulty and expense; 3, under the situation that propulsive effort is identical with " four claws " formula, cylinder block is short, has saved source of the gas during use, i.e. the energy; Safe and reliable when 4, using, card bearing up pulley rim and damage wheel rim not when having avoided the dismounting tire; 5, this device fabrication expense is low, performance good, quality is good, easy to maintenance, have tangible economic benefit.
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
With reference to Fig. 1, three claws can't harm the rim type tyre removing and replacing machine, comprise disk 6, and its concrete structure is: an end of cylinder block 7 is connected with disk 6; The other end is connected with an end of hanger 4, main connecting rod 3 by the axis of the piston (5), the other end of main connecting rod 3 is connected with triangle rotating disk 9, the triangle rotating disk is provided with two connecting rods 8 in two angles in addition, main connecting rod 3 is connected with claw 2 with the other end of two connecting rods 8, claw 2 is located in the slideway 1 spacing, and moves reciprocatingly in slideway.Its working process: produce 7.5kg/cm through air compressor
2Pressed gas send into simultaneously in two cylinder bands, the piston in the cylinder band obtains pressure and just drives the axis of the piston and do straight-line motion, its reciprocal process is to be finished by a foot-operated two-bit triplet commutation air valve.The two-piston axle all adopts hinge to be connected with drive connecting rod, drive connecting rod with the triangle rotating disk with hanger, hanger.Cylinder force will drive the triangle rotating disk is done certain angle (30 °) by up time or conter clockwise axial rotation by main connecting rod during work, meanwhile the triangle rotating disk drives in addition two follower link and main connecting rod is synchronized with the movement, so with also synchronous the moving reciprocatingly pointing on the track in the center of circle of three claws of three connecting rod bonded assemblys, thus finished when equipment uses to the chucking of wheel rim with unclamp.
Claims (1)
1, the harmless rim type tyre removing and replacing machine of a kind of three claws comprises disk (6), and it is characterized in that: an end of cylinder block (7) is connected with disk (6); The other end is connected with an end of hanger (4), main connecting rod (3) by the axis of the piston (5), the other end of main connecting rod (3) is connected with triangle rotating disk (9), the triangle rotating disk is provided with two connecting rods (8) in two angles in addition, main connecting rod (3) is connected with claw (2) with the other end of two connecting rods (8), and claw (2) is located in the slideway (1) spacing.
