Problems solved by technology

[0002] At present, the center frame of the machine tool realizes the auxiliary support function of the workpiece through the screw nut and the screw rod. On small and light machine tools, the weight of the workpiece is relatively light, and the damage to the screw nut and the screw rod is relatively slight. It affects the use of the steady frame, but on heavy-duty machine tools, due to the heavy weight of the workpiece (the machine tool bears more than 63 tons), when the workpiece is clamped, the weight of the workpiece is mainly through the adjustable top holder on the center frame base. Bearing, the screw nut and the screw rod must bear a large weight; when the steady frame bears the weight of the workpiece instantaneously, it will cause the deformation of the screw nut, which will affect the use

Embodiment Construction

[0025] Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described:

[0026] like figure 1 As shown, a hydraulic buffer device for a center frame of a heavy machine tool mainly includes a center frame base 1, a hydraulic buffer holding mechanism and an adjusting mechanism. The center frame usually includes an upper body of the center frame and a center frame base 1. The supporting member on the center frame base 1 is the main bearing part of the workpiece, and the supporting member here is also the most vulnerable to damage. The improvement of the present invention is mainly aimed at It is the holding part at this place, so that the holding part at this place can be buffered after being loaded instantaneously, so as to protect the holding part.

[0027] The center frame base 1 provides support for the hydraulic buffer jacking mechanism. The center frame base 1 is provided with a slide for the hydraulic buffer jacking mechanism to...

Abstract

The invention discloses a hydraulic buffer device for a center frame of a heavy machine tool. The buffer device comprises a center frame base, a hydraulic buffer jacking mechanism and an adjusting mechanism, wherein the hydraulic buffer jacking mechanism is arranged on the center frame base and comprises an adjustable jacking piece and a hydraulic buffer seat; the adjustable jacking piece is columnar and is in sliding fit with the center frame base; the hydraulic buffer seat is fixed to the center frame base and abuts against the end of the adjustable jacking piece; and the adjusting mechanismis arranged on the center frame base and acts on the adjustable jacking piece. Acting force brought by a workpiece can be buffered after instantaneous bearing of the adjustable jacking piece, abrasion of a lead screw and a nut is effectively avoided, and the service life of the center frame is prolonged.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a hydraulic buffer device for the center frame of a heavy machine tool. Background technique [0002] At present, the center frame of the machine tool realizes the auxiliary support function of the workpiece through the screw nut and the screw rod. On small and light machine tools, the weight of the workpiece is relatively light, and the damage to the screw nut and the screw rod is relatively slight. It affects the use of the steady frame, but on heavy-duty machine tools, due to the heavy weight of the workpiece (the machine tool bears more than 63 tons), when the workpiece is clamped, the weight of the workpiece is mainly through the adjustable top holder on the center frame base. To bear, the screw nut and the screw rod must bear a large weight; when the steady frame bears the weight of the workpiece instantaneously, it will cause the deformation of th...
