Abstract
The invention discloses automatic press-in equipment for an interference steel jacket on a rotating junction on an injection molding machine. The automatic press-in equipment is characterized by comprising an oil cylinder and a piston, wherein the piston capable of sliding in a sealing mode is arranged in the oil cylinder; the piston is fixedly provided with a piston rod; the piston rod penetrates out of the oil cylinder; the front end of the piston rod is provided with a steel jacket check ring and a baffle ring used for fixing the steel jacket; and the oil cylinder is communicated with a hydraulic system. The automatic press-in equipment has the advantages that the steel jacket is automatically pressed into the inner hole of a component by the equipment, so that assembling can be accurately carried out in a labor saving mode, and short time is consumed. Because the piston rod is pasted with a strain gage, tensile force borne by the piston rod can be monitored in real time; when the tensile force is overlarge, the direction of the steel jacket can be regulated in time until the monitored tensile force is within a normal range, so as to guarantee the steel jacket and the middle shaft of the inner hole, and the steel jacket can be accurately assembled; because the front end of the piston rod is provided with a steel jacket installation inclination proof mechanism, a pull rod used for installing the steel jacket is enabled to have a certain degree of freedom, and the phenomenon that the steel jacket is aslant pulled when being assembled to damage assembling components (such as a moving template and a rear template) due to the inclination of the piston rod can be avoided.
Description
Technical field
The present invention relates to a kind of erection unit of injection machine upper-part, particularly relate to the automatic press-fit equipment a kind of injection machine being rotationally connected place's interference steel jacket.
Background technology
When the rotatable parts on injection machine and other build-up member (as: moving platen, rear pattern plate etc.) are rotationally connected, usual needs first install steel bushing on the endoporus of this build-up member (i.e. moving platen, rear pattern plate etc.), then rotatable parts are assembled in steel bushing, to increase its wearability, and between steel bushing and the endoporus of build-up member, be interference fit.At present, the assembling of steel bushing is normally by manually driving in steel bushing in the endoporus of build-up member with hammer plug, but the method is more difficult for assembling the larger steel bushing of external diameter, spent time is also long, because the external diameter of steel bushing is larger, its magnitude of interference is larger, also larger with the contact surface of endoporus, causes the resistance suffered when assembling also larger.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind ofly assembles the automatic press-fit equipment short injection machine simple, consuming time being rotationally connected place's interference steel jacket.
The present invention solves the problems of the technologies described above adopted technical scheme: the automatic press-fit equipment a kind of injection machine being rotationally connected place's interference steel jacket, comprise oil cylinder and the piston being arranged on described in-oil cylinder salable slip, described piston is fixedly installed piston rod, described piston rod passes described oil cylinder, the front end of described piston rod is provided with steel bushing back-up ring for stationary steel bushing and baffle ring, and described oil cylinder is connected with hydraulic system.
Described piston rod posts foil gauge, and described foil gauge is electrically connected with deformeter.
The front end of described piston rod is provided with anti-steel bushing and installs leaning device.
Described anti-steel bushing is installed leaning device and is comprised pull bar, front universal joint and rear universal joint, described front universal joint and described rear universal joint bolt, ball is provided with in described front universal joint and described rear universal joint, the front end of described piston rod is wholely set the first positioning boss that periphery is sphere, the first described positioning boss matches with the ball of described rear universal joint, the rear end of described pull bar is wholely set the second positioning boss that periphery is sphere, the second described positioning boss matches with the ball of described front universal joint, described steel bushing back-up ring and described baffle ring are all arranged on the front end of described pull bar.
Described oil cylinder comprises cylinder body, protecgulum and bonnet, described protecgulum coordinates with the forward end seal of described cylinder body, described bonnet coordinates with the back-end sealing of described cylinder body, fixed by connecting rod between described protecgulum and described bonnet, described piston and described cylinder body seal are slidably matched, described protecgulum be respectively arranged with the oilhole be connected with described cylinder body in described bonnet, described oilhole is connected with described hydraulic system.
Described protecgulum is provided with the 3rd positioning boss, facilitates automatic press-fit equipment location in use, to prevent rocking of automatic press-fit equipment.
Compared with prior art, advantage of the present invention is can by among the endoporus of automatic for steel bushing pressing parts by this equipment, and it is laborsaving, accurate to assemble, and consuming time short; And owing to piston rod posting foil gauge, can pulling force suffered by Real-Time Monitoring piston rod, when pulling force is too large, the direction of steel bushing can be adjusted in time, until the pulling force monitored is in normal range (NR), thus ensure steel bushing and endoporus axis, steel bushing be assembled accurate; Again because the front end of piston rod is provided with anti-steel bushing installation leaning device, the pull bar for installing steel bushing is made to have certain free degree, avoid, because skew when the inclination of piston rod causes steel bushing to assemble, causing damaging build-up member (as: moving platen, rear pattern plate etc.).
