A kind of tyre turning mechanism
Technical field
The utility model belongs to mechanical field, is a kind of tyre turning mechanism specifically.
Background technology
In automobile manufacturing line tire delivery system, tire moves to car production assigned line under travel line drives, tire assembly station, need to carry out 90 degree of upsets to tire at this station, and according to the assembly technology of motor tire (180 degree of assemblings and 0 degree of assembling) requirement, carry out 180 degree of rotations, realize the correct location of tire on auto production line by the clamping of mechanism, upset, rotation.
Manipulator is mostly adopted to realize the clamping of tire, upset and rotation in the market.Tyre turning mechanism is integrated in one with line delivery, completes the fitting work of tire at travel line terminal (tire assembly station).This mechanism structure is compact, and degree of automation is high, and realize the clamping before to tire assembling, upset, rotates positioning function, is that tire assembles desirable, the most practical device.
Utility model content
The purpose of this utility model provides a kind of tyre turning mechanism.
For achieving the above object, the technical solution of the utility model, comprise frame, upset cylinder and fixing device, the top of described frame is provided with upset cylinder and bearing seat, crank shaft is provided with in described bearing seat, this upset cylinder is connected with crank shaft by crank connecting link, described crank shaft is fixedly connected with fixing device, this fixing device comprises clamping cylinder and clamp arm, described clamping cylinder is connected with clamp arm by tooth bar, gear, be bolted rotary cylinder in one end of described clamp arm, this rotary cylinder is connected with pivot arm by swivel bearing.
As preferably, the flip angle of described fixing device is 90 degree.
As preferably, the anglec of rotation of described pivot arm is 180 degree.
As preferably, described crank shaft side is fixed with locating piece.
Owing to adopting technique scheme, the beneficial effects of the utility model are:
1. fixing device is that clamping cylinder drives clamp arm, by tooth bar, gear power transmission, makes clamp arm do move toward one another, thus realizes clamping the centering of tire, and structure is simple, and clamping is steadily, economic and practical.
2., by upset air cylinder driven connecting rod crank axle, drive fixing device to realize the upset of 90 degree, tire, the application force on connecting rod is evenly distributed on crank shaft, and upset is steadily reliable, rotates flexibly.Through to the upset setting of cylinder stroke and the positioning action of 90 degree of locating pieces, avoid fixing device to be turned over position, guarantee that flip angle is accurate, safety.
3. be arranged on a pair rotary cylinder on clamp arm and achieve rotation synchronously, simple and practical, cost of manufacture is low.

Detailed description of the invention
As Fig. 1, shown in 2, the utility model comprises frame 1, upset cylinder 2 and fixing device 3, the top of described frame 1 is provided with upset cylinder 2 and bearing seat 4, crank shaft 5 is provided with in described bearing seat 4, this upset cylinder 2 is connected with crank shaft 5 by crank connecting link 6, described crank shaft 5 is fixedly connected with fixing device 3, this fixing device 3 comprises clamping cylinder 7 and clamp arm 8, described clamping cylinder 7 passes through tooth bar, gear is connected with clamp arm 8, rotary cylinder 9 has been bolted in one end of described clamp arm 8, this rotary cylinder 9 is connected with pivot arm 11 by swivel bearing 10.
The flip angle of described fixing device 3 is 90 degree.
The anglec of rotation of described pivot arm 11 is 180 degree.
Described crank shaft 5 side is fixed with locating piece 12.
Principle of work of the present utility model: when tire is through rollgang, when arriving the initial flip bit of tire, clamping cylinder 7 works, clamp arm 8 move toward one another, and driven rotary arm 11 clamps tire in opposite directions; Now overturn cylinder 2 to work, fixing device 3 is turned over and turn 90 degrees; Rotary cylinder 9 works, and driven rotary arm 11 revolves turnback; Again according to contrary sequential working, structure resets, and completes an omnidistance job.
