Abstract

The invention discloses a workpiece combined clamp for an abrasive wheel cutting machine, which comprises a clamping mechanism and an elastic movement mechanism, wherein the clamping mechanism comprises a press plate for holding a workpiece and a bottom plate, and a compacting screw and an adjusting bolt are arranged between the press plate and the bottom plate; the elastic movement mechanism is arranged below the clamping mechanism and comprises a screw rod, the middle part of the screw rod is provided with a cam, and a screw rod nut is fastened to a work table; a guide sleeve is arranged on the work table, a guide post is arranged in the guide sleeve, a spring is arranged on the guide post, and the top of the guide post is positioned in a groove in a panel on the lower side of the bottom plate and forms a clearance fit with the groove; and the lower side of the work table forms a slide fit with a guide rail through a fixed slide block. The combined clamp can conveniently and quickly clamp the workpiece. In the cutting process, the workpiece can make a back-and-forth up-and-down aggregate reciprocating motion, thereby being beneficial to reducing cutting resistance, facilitating the discharge of cuttings, avoiding binding, preventing an abrasive wheel from damage, enhancing the work efficiency of the abrasive wheel cutting machine and enabling the cutting process to be safer.

Description

A kind of workpiece combined clamp for abrasive wheel cutting machine
Technical field
The present invention relates to a kind of workpiece combined clamp for abrasive wheel cutting machine, belong to quick, the safe Workpiece clamping device of Machining Technology field abrasive wheel cutting machine special use.
Background technology
The cutting of use emery wheel is that field of machining is to workpiece processing mode commonly used.In the prior art, usually adopt stationary fixture to be installed during the abrasive wheel cutting machine cut workpiece, step up or the leading screw clamping device as pressing plate, the defective of its existence is in cutting grinding wheel binding phenomenon to take place easily during than the part of major diameter or comparatively large cross-sectional area, damage grinding wheel, reduce operating efficiency, increase cost, when serious, cause and to finish cutting even cause the accident.
Summary of the invention:
The object of the present invention is to provide a kind of conveniently clamping work pieces, and can reduce the abrasive wheel cutting machine cutting resistance in when work, avoid the binding phenomenon, the workpiece combined clamp for abrasive wheel cutting machine of fragile grinding wheel not, to improve the operating efficiency of cutting machine, satisfy demand than the quick clamping of part in cutting of major diameter or sectional area.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of workpiece combined clamp for abrasive wheel cutting machine, form by clamp mechanism and elastic movement mechanism, wherein, said clamp mechanism comprises the pressing plate and the base plate of holding workpiece, between pressing plate and base plate, be provided with the clamping screw that cooperates with the pressing plate cross-under and pressing plate and base plate are fixed, workpiece is fixed by the clamping screw adjustment in the middle of being clamped in by pressing plate and base plate.Said elastic movement mechanism comprises leading screw below clamp mechanism, at the middle part of leading screw cam is installed, and feed screw nut and workbench are fastenedly connected.Guide pin bushing is housed on workbench, is provided with guide pillar in the guide pin bushing, spring is housed on the guide pillar, guide pillar slides up and down in guide pin bushing, and the capital of guide pillar is positioned at groove and movable with it cooperation that base plate downside panel is opened.The downside of workbench is slidingly matched by fixing slide block and with guide rail.When the cutting feeding, the rotation of motor-driven leading screw, the leading screw rotation drives workbench by feed screw nut simultaneously and anchor clamps move forward and backward along guide rail, because guide pin bushing and action of cam make whole anchor clamps when guide rail moves, also make whole anchor clamps do upper and lower fine motion, thereby the workpiece that drives between base plate and the pressing plate is done front and back and is moved up and down, and the cutting resistance when reducing abrasive wheel cutting machine work is avoided the binding phenomenon, not fragile grinding wheel is realized cutting.
In order to adjust the clamping degree of workpiece, being provided with between pressing plate and base plate is threaded with pressing plate adjusts the adjustment bolt of pressing plate and base plate clamping degree.
For the clamped position of adjusting workpiece and the workpiece that adapts to the different cross section size, on the top panel of base plate, be provided with the T-shape groove, the lower end of clamping screw and this T-shape groove are slidingly matched.
The invention has the beneficial effects as follows: clamping work pieces quickly and easily, workpiece has front and back and aggregate motion up and down reciprocatingly in the process of cutting, help reducing the cutting resistance, make things convenient for the discharge of smear metal, avoid the binding phenomenon, prevent to damage grinding wheel, improve the operating efficiency of abrasive wheel cutting machine, make cutting process safer.

The specific embodiment
The specific embodiment that provides below in conjunction with accompanying drawing and accompanying drawing is further described the present invention.
See Fig. 1 and Fig. 2, a kind of workpiece combined clamp for abrasive wheel cutting machine is made up of clamp mechanism and elastic movement mechanism, and said clamp mechanism comprises the pressing plate 8 and the base plate 9 of holding workpiece, and workpiece 4 is clamped between pressing plate 8 and the base plate 9.Between the upper end of pressing plate 8 side guide 8 and base plate 9, be provided with clamping screw 6 and the clamp nut 5 that cooperates with pressing plate 8 cross-under unthreaded holes, adjust clamp nut 5 and can compress or unclamp clamping or elasticity workpiece.Be provided with the T-shape groove at base plate 9 top panels, the lower end of clamping screw 6 and this T-shape groove are slidingly matched, and can adjust the clamped position of workpiece and the workpiece of adaptation different cross section size.Between the upper end of pressing plate 8 opposite side pressing plate 8 and base plate 9, be provided with the adjustment bolt 7 that is threaded with pressing plate 8, in order to adjust the clamping degree of workpiece or to finely tune.Said elastic movement mechanism comprises leading screw 11 below clamp mechanism, leading screw 11 middle parts are equipped with cam 16 by block 3, key 2, feed screw nut 15, and feed screw nut 15 is fastenedly connected with workbench 13.Be installed with 4 groups of guide pin bushings 1 on workbench, be provided with guide pillar 17 in the guide pin bushing 1, spring 10 is housed on the guide pillar 17, guide pillar 17 slides up and down in guide pin bushing, the capital of guide pillar 17 be positioned at groove that base plate 9 downside panels are opened and with its movable cooperation.The downside of workbench 13 is fastenedly connected with slide block 12, and workbench 13 is slidingly matched by slide block 14 and guide rail 12.When the cutting feeding, 11 rotations of motor-driven leading screw, leading screw 11 rotations drive workbench 13 and anchor clamps front and back motion on guide rail 12 by feed screw nut 15 simultaneously, because the effect of guide pin bushing 1 and cam 16, make whole anchor clamps when guide rail moves, also make whole anchor clamps do upper and lower fine motion, thereby the workpiece that drives between base plate and the pressing plate is done front and back and moved up and down, realize the cutting feeding, and prevented the generation of grinding wheel binding phenomenon.
