Abstract
The utility model relates to a clamping fixing device, which consists of an upper chuck (3), a center mechanism (4) and a center mechanism piston rod (5) and has the different points that the upper end of the center mechanism piston rod (5) is connected with two half rings (1); the center mechanism piston rod (5) is fixed by the upper ends of the two half rings (1) through a ring locking sleeve (2); and the lower ends of the two half rings (1) are connected with the upper chuck (3). Therefore, the clamping fixing device has a simple structure, is rapid, convenient and reliable to operate, has high working efficiency and is particularly suitable for production in the tyre manufacturing industry.
Description
Technical field:
The utility model relates to the equipment that a kind of tire manufacturing industry is produced, particularly a kind of clamping and fixing device.
Background technology:
At present, fixedly employing two semi-rings and the screw of platen and central authority fixed on the capsule of domestic automatic tire vulcanizer, after capsule and upper chuck are in place, with two semi-rings capsule upper chuck and central authority piston rod are fastened, and it is two semi-rings and center piston bar cramp are tight with screw, this screw connects two fastening semi-ring clamping and fixing device troublesome poerations, the maintenance worker wants knockout screw when changing capsule, also to tighten once more after the installation, waste time and energy, it is higher that loosening frequency appears in screw after work a period of time, causes that capsule upper chuck position changes, and influences the reliability of equipment.
Summary of the invention:
The purpose of this utility model just provide a kind of simple in structure, the operation quick and convenient, reliable, the clamping and fixing device of high efficiency.
The purpose of this utility model is achieved in that a kind of clamping and fixing device, form by upper chuck, central authority, central authority piston rod, the upper end that it is characterized in that the central authority piston rod connects two semi-rings, the upper end of two semi-rings is fixed described central authority piston rod by the lock ring cover, and the lower end of two semi-rings is connected with upper chuck.
An optimum implementation of the present utility model is: there is annular groove the upper end of central authority piston rod.
The utility model compared with prior art has the following advantages:
Owing to adopt the upper end of central authority piston rod to connect two semi-rings, the upper end of two semi-rings is fixed described central authority piston rod by the lock ring cover, the type of attachment that the lower end of two semi-rings is connected with upper chuck, thus simple in structure, the operation quick and convenient, reliable, high efficiency.
Description of drawings:
Figure: be the utility model concrete structure schematic diagram
1, two semi-rings 2, lock ring cover 3, upper chuck 4, central authority 5, central authority piston rod
The specific embodiment:
The upper end of central authority piston rod 5 connects the upper end of two semi-rings, 1, two semi-ring 1 to be fixed described central authority piston rod 5 by lock ring cover 2, and the lower end of two semi-rings 1 is connected with upper chuck 3, and there is annular groove the upper end of central authority piston rod 5.
During use, connection effect drive upper chuck 3 by two semi-rings 1 during 5 actions of central authority piston rod moves together, lock ring cover 2 entangles two semi-rings 1 can not separate its firm lumping together, it is just separable in the time will changing capsule lock ring cover 2 to be extracted two semi-rings 1, and upper chuck 3 just can break away from central authority piston rod 5.
Claims (2)
1. clamping and fixing device, form by upper chuck (3), central authority (4), central authority piston rod (5), the upper end that it is characterized in that central authority piston rod (5) connects two semi-rings (1), the upper end of two semi-rings (1) is fixing with described central authority piston rod (5) by lock ring cover (2), and the lower end of two semi-rings (1) is connected with upper chuck (3).
2. a kind of clamping and fixing device according to claim 1 is characterized in that there is annular groove the upper end of central authority piston rod (5).
