Description
Technical field
The utility model belongs to hydraulic press, particularly relates to a kind of unbalance loading of hydraulic press guide rail and a kind of guide rail structure that can regulate the location automatically of guide rail distortion adjusted.
Background technology
The work of hydraulic press mainly is to be fixed on slide block on the guide rail by hydraulic oil cylinder driving, makes guide rail along upper and lower the moving of guide plate that is arranged on the liquid machine pillar, thereby makes slide block carry out punching press to the mould on the workbench that is positioned at its downside.
Usually, the spigot surface of the guide rail that guide shoe moves on the used hydraulic press is vertical face, adding the slip generation thermal expansion of man-hour because of guide rail, because the spigot surface of guide rail is vertical guide face, is formed with the angle with guide plate and even touches, and do not have the compensate for clearance of thermal expansion, so as long as generation thermal expansion, guide rail just will be stuck in its position, and at this moment oil cylinder also moves at the driving slide block, will cause the wearing and tearing of guide rail.
And, at present along with large hydraulic press has appearred in industrial expansion, as the appearance of the large hydraulic press of several kilotons.For the large hydraulic press of several kilotons, because the increasing of its processing work, slide block will strengthen, because the increasing of slide block will cause the unbalance loading of guide rail, directly influences the work of hydraulic press.
Summary of the invention
The utility model provides a kind of a kind of guide rail structure that can regulate the location automatically that can adjust the unbalance loading of hydraulic press and have the thermal deformation of automatic opposing hydraulic press for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of guide rail structure that can regulate the location automatically, include slide block, the guide rail that is connected with slide block and first guide plate, second guide plate and hydraulic press pillar, described first guide plate is fixed on the guide rail, second guide plate is fixed on the plane of pillar, wherein, the joint face of the guide rail and first guide plate is a planar structure, and first guide plate and second guide plate are plane contact; On a side of guide rail, also be provided with and be used to adjust the adjustment structure that guide rail moves horizontally.
Described adjustment structure includes fixed block, draws screw and screw, wherein, fixed block is positioned at a side of guide rail and fixedlys connected with slide block, be formed with screw on the fixed block with the perpendicular perforation in this side of guide rail, the periphery of screw is formed with screw thread, and penetrate the screw of fixed block and fixed block spiral shell and link and connect, screw is formed with through hole along central shaft in it, draws screw to run through behind the through hole at screw center to link with the guide rail spiral shell to connect.
Also be provided with adjusting pad between described fixed block and the guide rail.
The bottom that is positioned at guide rail one side at fixed block also is connected with backplate.
Advantage and the good effect that the utlity model has are: because the adjustable gib of anti-bias load of the present utility model and thermal deformation, guide rail beveling with hydraulic press, making guide rail and guide plate be completed into face contacts, when guide rail generation thermal expansion, as long as it is mobile that guide rail has slightly along the contact-making surface with guide plate, just adjusted its distortion automatically.Owing to be provided with the screw of adjusting guide rail position and draw screw, can and draw screw to adjust moving horizontally of guide rail simultaneously, thereby overcome the unbalance loading of guide rail very easily and carry out the adjustment in precision letter guide rail contact-making surface gap by screw.
