Manipulator tyre gripper

Abstract

The invention relates to a manipulator tyre gripper, which comprises an upper plate, a lower plate, six to twelve claws, a second reduction motor, a screw rod, a nut, a first connecting rod, second connecting rods, third connecting rods, fourth connecting rods, rotary blocks, two pulling rods, two bearing seats and two bearings, wherein the second connecting rods, the third connecting rods, the fourth connecting rods and the rotary blocks are as many as the claws; the second reduction motor is fixed on the lower plate; a rotary shaft of the second reduction motor is fixedly connected with thescrew rod; two ends of the screw rod are respectively inserted into inner rings of the corresponding bearings and fixed with the inner rings of the bearings; the nut comprises a screw rod part and a connecting rod part; the nut is sleeved on the screw rod by the screw rod part of the nut, rotatably connected with the screw rod and hinged with one end of the first connecting rod by the connecting rod part of the nut; the other end of the first connecting rod is hinged with an adjacent angle part of two angle parts outside the adjacent rotary block; and the angle part is also hinged with one ofthe second connecting rods. The manipulator tyre gripper is stable in operation, safe and reliable.

Description

[0001] This application is a divisional application of Chinese Invention Patent Application No. 200910303996.2, the filing date of the original application: July 3, 2009, and the name of the invention: translational vulcanizing machine. technical field [0002] The invention relates to a tire gripper of a tire loading and unloading device of a translation vulcanizer. Background technique [0003] In the process of producing engineering giant radial tires, the vulcanization process greatly improves a series of physical and mechanical properties of rubber such as modulus, elasticity, hardness, and tensile strength. The quality of tire vulcanization largely determines the quality of tires. performance. As the load capacity of construction machinery increases, the size of the tires used is also increasing. The lower body of the steam chamber of the translation vulcanizer is stationary, and the upper body of the steam chamber moves in translation with the frame, which is widely ...

AI Technical Summary

Problems solved by technology

For a translation vulcanizer mentioned in Chinese patent document CN200610026201.4, if the translation support has a large span, during the translation process, due to the asynchronous left and right translation cylinders, the support will generate large stress and deformation, which will seriously affect the operation of the whole machine. Stability and service life

During the vulcanization process of the steam chamber of the vulcanizer, the clamping force is as high as 3,000 to 3,900 tons, and the pressurization device is required to be stable and reliable. If multiple piston cylinders are used to pressurize together, stress differences will occur due to uneven force, which will shorten the life of the piston rod. Greatly reduced
