The utility model mainly determines the design of the tire clamping device according to the diameter and thickness of the tire and the quality of the tire. The design of the tire clamping device can not only meet the production needs of the enterprise, but also save materials to the greatest extent. The tire clamping device is mainly completed through the operation and coordination of the four-bar mechanism. The task of grabbing and dropping tires. Grab and put down the tire by analyzing the kinematic coordination between the piston rod, the connecting part and the gripper. First of all, the grab bar for grabbing the tire should be set up to grab the tire just in time, and the grab bar cannot break the tire, so the tire should be protected. An arc-shaped rubber pad can be added to the end of the grab bar, connected by bolts, and the rubber pad has a curvature that just meets the diameter of the tire. When the grab bar just wraps the tire, the arc of the rubber pad also coincides with the tire , satisfying the condition that the tire is raised. Secondly, the expansion and closing of the connecting rod is realized by the connecting piece. When the connecting piece moves upwards, it can drive the grab bar to close tightly and grab the tire. As the link moves down, the grab bar expands, releasing the tire. And the joint movement of tire clamping device is mainly realized by the piston rod of air cylinder. The reciprocating motion of the cylinder piston realizes the reciprocating motion of the connecting piece.

Beneficial effects of the utility model: the design mainly determines the design of the tire clamping device according to the diameter and thickness of the tire and the quality of the tire. The design of the tire gripping device can not only meet the production needs of the enterprise, but also reduce the parts of the manipulator as much as possible and simplify the gripping method of the manipulator, which can greatly improve the efficiency of the enterprise's production and enhance the competitiveness of the enterprise.

Detailed ways

The grabbing rod is divided into an upper connecting rod and a lower grabbing plate, and the upper and lower parts are embedded and connected in the form of welding. According to the tire's diameter of 1070mm and width of 250mm, determine the size of the connecting rod and the size of the tray so that it can meet the requirements of grabbing the tire. The size of the lower tray of the grab bar is set to about half the size of the tire, that is, the size of 500mm. At this time, the tire can be caught just right, so that the material will not be wasted, and the tire can be lifted up well. The size of the upper part of the connecting rod is 60*60mm, and the square steel with a thickness of 6mm can be selected. This size is just enough to hold the tire and the gap is appropriate.

Determination of the support plate. When the grabbing rod is at the lower part of the cylinder, the up and down movement of the piston rod can just drive the grabbing movement of the grabbing rod, and then grab the tire to realize the transmission of the tire. Through research, the support frame can be designed as a square steel plate, on which the cylinder can be installed and axially fixed through the 4 bolt holes in the middle. The large hole in the middle is prepared for the passage of the cylinder piston rod. The design of opening four more holes on the periphery of the cylinder is to facilitate the connection of the cylinder with other parts to complete more movements.

The support ears are connected to the side of the support plate by 2 screws. Both sides of the groove at the lower end of the support ear are respectively provided with holes to facilitate the use of pins to connect the grab bar and the support ear.

Connector design. The hole at the front end and the rear end hole are connected by a round pin to connect the two catch bars with a round pin, so that the connecting rod grabs the tire and puts down the tire.

Combining the mass of the tire, the connecting piece and the two grab bars, the total mass is 168Kg, which means that it takes about 1680N of force to pick up the tire. Under the condition that the working pressure is 0.5pa, when the bore diameter of the cylinder is 100mm, it can meet the requirements of the clamping device. JSC standard cylinder is selected, with a bore of 100mm and a stroke of 200mm. Considering that the bottom end of the cylinder is a screw mandrel, so the cooperation of the screw mandrel and the threaded hole can be used. Tapping is carried out at the central position of the connecting piece, and the threaded hole is M20mm, which just meets the screw connection requirements of the cylinder. Now, when the piston rod moves up and down, it can also drive the connecting piece to move up and down.

The grabbing rod and the rubber pad are connected by bolts, and the two rubber pads are respectively made into four counterbore holes and connected with the grabbing rod through hexagon socket bolts. Making the rubber pad into an arc is also to better fix the tire. When the size of the tire is less than 1070mm, the grabbing rod grabs the tire, which will support the lower part of the tire, and the force-bearing area of the tire will also increase, and the task can be better completed.

The overall structural installation sequence of the tire clamping device adopts the order of installation from top to bottom. The working principle of this device is the development and application of the four-bar structure, which generates power through the cylinder to drive the grab bar to grab the tire.
