The utility model content
The utility model is not suitable for the deficiency that position, less space and riveted joint mode exist at what existing squeezed riveting equipment existed, and a kind of simple in structure, small-sized squeezed riveting device that volume is little, easy to operate is provided.
The utility model is achieved by the following technical solution: a kind of squeezed riveting device, comprise hydraulic cylinder and the supporting seat that is located at the hydraulic cylinder front end, the cylinder body of hydraulic cylinder has former and later two cylinder bodies, respectively be provided with a piston in former and later two cylinder bodies, wherein, the outside end face that is located at the piston in the cylinder body of rear end is provided with oil through to the top of its piston rod, and this oil through can be connected with external oil pipe; The piston rod that is located at the piston in the front end cylinder body can be connected with the squeezed riveting parts, carries out the squeezed riveting operation.The supporting seat that the utility model is located at the hydraulic cylinder front end is a prior art, and any structure form that it can adopt prior art repeats no more here.
Hydraulic cylinder of the present utility model adopts the round trip oil cylinder, the active force of two pistons can be acted on workpiece simultaneously, the speed of its squeezed riveting is fast, the squeezed riveting forming, and under the same active force, the volume of round trip cylinder is little, in light weight, makes it be more suitable for operation in less space.The interior oil circuit design of this hydraulic cylinder connects the outer no numerous and diverse pipeline of cylinder body, makes its overall structure simpler, easy to operate.
In order to make the utility model be suitable for the operation and the convenient for maintaining in less space, the supporting seat that the utility model will be located at the hydraulic cylinder front end and the cylinder body of hydraulic cylinder are by being threaded, supporting seat is provided with work nest, crushing block and back crushing block before being provided with relatively in the work nest, the end that supporting seat is connected with hydraulic cylinder body has the hole that cooperates with piston rod, the piston rod of the piston in the cylinder body of hydraulic cylinder front end connects by this Kong Yuhou crushing block, also is provided with back-moving spring on the piston rod.The utility model drives the back crushing block by the piston in the front end cylinder body and moves forward by the effect of round trip cylinder, realizes the extrusion modling of screw.Back-moving spring is used for the piston in the front end cylinder body is automatically reset, and the piston in the cylinder body of rear end is automatically reset.
For the ease of maintenance, the utility model is provided with a bonnet in the rear end of hydraulic cylinder body equally, and this bonnet and cylinder body which is provided with oil through by being threaded.
Other parts of the present utility model adopt prior art, repeat no more here.
The utility model is simple in structure owing to adopt the round trip oil cylinder, two pistons act on the screw simultaneously with joint efforts, squeezed riveting speed is fast, the squeezed riveting forming, and pass through structural design cleverly, its overall volume is reduced, easy to operate, make it be more suitable for operation in less space; Adopt between the supporting seat of the utility model front end and bonnet and the cylinder body to be threaded, make maintenance convenient, only need unclamp respective threads during maintenance and connect, can take out each parts and clear up, keep in repair, change, and maintenance cost is low.
