Description
Technical field
The utility model relates to a kind of forcing press, particularly a kind of press ram guiding clearance adjusting device.
Background technology
The slider guide gap of current traditional forcing press is stated on the lower method and is realized, interior hexagonal cylindrical end holding screw (state label GB/T79-2000) is screwed in the screwed hole of press frame side, with inner hexagon spanner turn screw, rely on screw end face to prop up side rails to ensure the motion guide of press ram, because holding screw face area is less, the pressure that screw produces on side rails will be larger, in the time of forcing press unbalance loading stamped workpieces, the position that can contact with side rails at screw produces " pit ", long-term use can make forcing press slider guide precision worse and worse, even can affect the service life of forcing press.
Utility model content
The purpose of this utility model is, overcomes problems of the prior art, and a kind of press ram guiding clearance adjusting device is provided, and simple in structure, easy to adjust, the precision of lathe is high.
For solving above technical problem, a kind of press ram of the present utility model guiding clearance adjusting device, comprise fuselage body and be arranged on slide block moving up and down on fuselage body, the both sides of described slide block are respectively equipped with guiding position, the front side at described guiding position fits with fromer rail respectively, the side at described guiding position fits with side rails respectively, described fromer rail is fixedly mounted on described fuselage body, also comprise eccentric shaft, described eccentric shaft comprises that axis is parallel to each other and has larger diameter end and the smaller diameter end of eccentric throw, the larger diameter end of described eccentric shaft from front to back level is plugged in the counterbore of described side rails, the smaller diameter end of described eccentric shaft from back to front level is plugged in the through hole of described fromer rail, the counterbore internal diameter of described side rails and the external diameter of described eccentric shaft larger diameter end are suitable, the through hole internal diameter of described fromer rail and the external diameter of described eccentric shaft smaller diameter end are suitable.
With respect to prior art, the utility model has been obtained following beneficial effect: because fromer rail is fixed, the smaller diameter end of eccentric shaft is fixed on fromer rail, in the time that eccentric shaft rotates, the larger diameter end of eccentric shaft can move left and right with side rails, realizes the adjustment in slide block side guide gap; Because the contact area of eccentric shaft and fromer rail and side rails is larger, the pressure of contact site is smaller, in the time of forcing press unbalance loading stamped workpieces, is difficult for producing " pit " at the position of side rails contact, ensures the guiding accuracy of slide block.
As improvement of the present utility model, the front end of described eccentric shaft smaller diameter end stretches out from the through hole of described fromer rail, and the longitudinal section, termination of stretching out fromer rail is square.Spanner eccentric rotation axis is convenient to use in square termination.
As improvement of the present utility model, the eccentric throw of described eccentric shaft is the half of slider guide adjusting play.Eccentric shaft rotates one week, the twice that the maximum displacement that its left and right directions can be realized is eccentric throw, and this displacement is slider guide adjusting play.
As improvement of the present utility model, on described fromer rail, be fixed with locking plate by screw, described locking plate is pressed in the root of the square termination of eccentric shaft by eccentric shaft axial restraint.Square termination and smaller diameter end form the shaft shoulder, and locking plate is pressed in eccentric shaft on the shaft shoulder and realizes axial restraint.
