Abstract
The utility model discloses a bicycle large chain wheel crank shaft riveting press, and relates to the technical field of bicycle production equipment. The bicycle large chain wheel crank shaft riveting press comprises a riveting machine main body, a motor, a pressing wheel mechanism, a worktable and a lifting mechanism. The motor is connected with a rotary shaft of the pressing wheel mechanism. A positioning head is fixed to the worktable, and the lifting mechanism is arranged on the worktable. The lifting mechanism is composed of a transmission rod, a hydraulic cylinder and an operation rod. The transmission rod is linked with the hydraulic cylinder, and the operation rod is linked with a switch of an oil path system of the hydraulic cylinder. The pressing wheel mechanism comprises a longitudinal rotary shaft, a transverse rotary shaft and pressing wheels, wherein the longitudinal rotary shaft is connected with the transverse rotary shaft, the transverse rotary shaft is provided with a pair of the pressing wheels, and the section of the bearing face of each pressing wheel is arc-shaped. A bicycle large chain wheel and a crank shaft can be riveted by means of the rotary arc-shaped pressing wheels. The riveting surface of a product is attractive, riveting strength is large, a riveted opening of the crank shaft is not prone to being cracked, the operation process is safe, and noise is low.
Description
Technical field
The utility model relates to bicycle production equipment technical field.
Background technology
At present, generally to adopt the punching press riveter to rivet fixing with turning axle for the bicycle hinge wheel: during work, first with hinge wheel with turn axle sleeve and be connected together and be fixed on the punching press riveter workbench, carry out punching press with drift to turning axle riveted joint mouth.But because drawing velocity is fast, be not easy control, make easily and turn axle riveted joint mouthful cracking, and the noise of punching press riveter greatly, product surface not energy-conservation, that punching press obtains coarse not attractive in appearance, product percent of pass is low.
The utility model content
For existing bicycle hinge wheel with turn defective and the deficiency that the axial compression riveter is wayward, product is easy to crack, noise is large, the utility model proposes a kind of bicycle hinge wheel and turn the axial compression riveter, the intensity of its riveted joint is high, turns axle riveted joint mouth and is not easy cracking, safe operation process, easy to operate, noise sound is little.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of bicycle hinge wheel turns the axial compression riveter, comprises riveter main body, motor, pressing wheel mechanism, workbench, positioning head, elevating mechanism; Motor is connected rotating shaft and is connected with pressing wheel mechanism, positioning head is fixed on the workbench, workbench and elevating mechanism interlock.
Pressing wheel mechanism comprises vertical rotating shaft, laterally rotating shaft, pinch roller; Vertically rotating shaft connects with the rotating shaft of being connected, and laterally rotating shaft is provided with a pair of pinch roller, and the section of the pressure-bearing surface of pinch roller is arc.Positioning head is fixed on the workbench, diameter turns axle riveted joint mouthful diameter less than bicycle, highly be no more than the thickness that turns axle, and positioning head and vertical rotating shaft are on same axis, when the bicycle hinge wheel turned the work of axial compression riveting staving press, positioning head entered and turns axle riveted joint mouth, and bicycle hinge wheel and the position of turning axle are fixed, when workbench promotes the bicycle hinge wheel and turns axial upper the movement, turn axle riveted joint mouth over against vertical rotating shaft.
Pressing wheel mechanism is in when work, and the laterally relative pinch roller rotation in rotating shaft two ends is carried out roll extrusion and ground and close turning axle riveted joint mouth, and the arc-shaped sections of the pressure-bearing surface of pinch roller will turn axle riveted joint mouth and be pressed into arc.
Elevating mechanism comprises drive link, hydraulic cylinder, action bars; Drive link and hydraulic cylinder interlock, the switch gearing of action bars and hydraulic cylinder oil piping system.Adopt the elevating mechanism of fluid pressure type, the moving up and down of push work platform drives the bicycle hinge wheel and turns axle and move, and the elevating mechanism speed of fluid pressure type is slow, and operating process is subject to the control of hydraulic cylinder oil piping system switch.And the thrust that the elevating mechanism of fluid pressure type produces is large, and the destructive power of impacting generation is little, can not cause and turn axle riveted joint mouth because rolling cracking.
The beneficial effects of the utility model be arc pinch roller by rotation to the bicycle hinge wheel with turn axle and press, the product that the obtains surface aesthetic that presses, the intensity of riveted joint, turning axle riveted joint mouth, to be not easy cracking, safe operation process, noise sound little.
Description of drawings
Fig. 1 is the structural representation that the utility model bicycle hinge wheel turns the axial compression riveter;
Fig. 2 is Fig. 1 pressing wheel mechanism structural representation;
Fig. 3 is bicycle hinge wheel and the structural representation that turns axle;
Among the figure, 11 riveter main bodys, 12 motor, 13 pressing wheel mechanisms, 14 elevating mechanisms, 141 drive links, 142 action bars, 143 hydraulic cylinders, 15 workbench, 16 positioning heads, 21 vertical rotating shafts, 22 pinch rollers, 23 horizontal rotating shafts, 31 hinge wheels, 32 turn turning before axle, 33 processing and turn axle riveted joint mouthful after axle riveted joint mouthful, 34 processing.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
The described bicycle hinge wheel of Fig. 1 embodiment turns the axial compression riveter and comprises riveter main body 11, motor 12, pressing wheel mechanism 13, workbench 15, positioning head 16, elevating mechanism 14; The rotating shaft that motor 11 is connected with pressing wheel mechanism connects, and positioning head 16 is fixed on the workbench 15, workbench 15 and elevating mechanism 14 interlocks.Elevating mechanism 14 comprises drive link 141, action bars 142, hydraulic cylinder 143; Drive link 141 and hydraulic cylinder 143 interlocks, the switch gearing of action bars 142 and hydraulic cylinder 143 oil piping systems.
Vertical rotating shaft 21 that the described pressing wheel mechanism 13 of embodiment comprises among Fig. 2, laterally rotating shaft 23, pinch roller 22; Vertically rotating shaft 21 connects with the rotating shaft of being connected 23, and laterally rotating shaft 23 is provided with a pair of pinch roller 22, and the section of the pressure-bearing surface of pinch roller 22 is arc.
The utility model bicycle hinge wheel turns the axial compression riveter in when work, with the hinge wheel 31 of bicycle and turn axle 32 and be fixed on the workbench 15 by positioning head 16, opens motor 12, pressing wheel mechanism 13 this moment High Rotation Speed under the drive of motor 12; Use action bars 142 control hydraulic cylinders 143, thus the hinge wheel on push work platform 15 and the workbench 15 31 and turn axle 32 and upwards rise, and the axle riveted joint mouthfuls 33 of turning before the processing contacts and produces pressure with pinch roller 22.Turning axle riveted joint mouthfuls 33 before the processing grinds to close in pinch roller 22 High Rotation Speeds, roll extrusion and turns axle riveted joint mouthfuls 34 after being processed to process down.
