Abstract
The invention discloses a synchronous centering and clamping mechanism which comprises a base. Two sliding blocks are arranged on the base through sliding rails, a nut is fixedly arranged in each sliding block, the two nuts are both matched with the same lead screw, the rotating directions of the threads of the two nuts are opposite, one end of the lead screw is connected with the output shaft of a motor, a chuck is connected to each sliding block, and clamping blocks for clamping workpieces are arranged on the opposite inner sides of the two chucks. The synchronous centering and clamping mechanism is simple in overall structure, small in occupied space, accurate in centering and alignment, convenient to mount and maintain and capable of improving machining quality.
Description
Technical field
The present invention relates to a kind of clamp mechanism, particularly a kind of for mach synchronous centering clamp mechanism.
Background technology
Often need to carry out clamping to workpiece in machined, also must consider the problem of centering to being fixedly clamped of axial workpiece, the mechanism of current clamping axial workpiece is comparatively complicated, take up room large, clamping centering trouble, accuracy of alignment is not high, affected crudy, versatility is poor.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, take up room the centering of little, centering precisely, improve crudy, synchronous centering clamp mechanism that applicability is wide, overcome the deficiencies in the prior art.
Synchronous centering clamp mechanism of the present invention, comprise base, by slideway, two slide blocks are installed on base, all be installed with screw in each slide block, two screws all match with the same filament thick stick but the rotation direction of screw thread is contrary, one end of leading screw is connected with the output shaft of motor, all is connected with chuck on each slide block, and two relative inboards of chuck are provided with the fixture block of holding workpiece.
Synchronous centering clamp mechanism of the present invention, have vertical hole on wherein said base, in this vertical hole, be fitted with column; There is jack at the middle part of column, and insert in this jack at the middle part of described leading screw, and there are two shaft shoulders at the leading screw middle part, and two shaft shoulder medial surfaces just are stuck in the both sides of jack bottom, column middle part, and there is the concave surface of supporting workpiece the upper end of column; The lower end of column has spring to lean with the plug be connected with whorl of base; Establish axial adjusting pad between screw and slide block.
Synchronous centering clamp mechanism of the present invention, have the tank filler sleeve that leads to rubbing surface between column and the shaft shoulder on wherein said column.
Synchronous centering clamp mechanism of the present invention, during work, the driven by motor leading screw rotates, leading screw drives two screws simultaneously and moves, because the hand of spiral of two screws is contrary, two screws move in opposite directions, drive two slide blocks and move in opposite directions with respect to base, slide block internal fixture block mutually presss from both sides to being positioned at middle shaft-like workpiece.Reach the purpose of centering clamping.By adjusting the thickness of axial adjusting pad, the position of capable of regulating holding workpiece centering.Before clamping, first workpiece is placed on the concave surface of column upper end, automatic capturing after clamping, the bottom of column is owing to spring supporting being arranged in quick condition.The axial limiting of leading screw by column, with the side of two shaft shoulders, coordinated carry out spacing.Overall structure is simple, takes up room little, and accurately, installation and maintenance are convenient, can improve machining quality in centering centering.
The accompanying drawing explanation
Fig. 1 is the structural representation of the specific embodiment of the invention.
The specific embodiment
As shown in Figure 1: 1 is base, on base 1, by slideway, two slide blocks is installed, i.e. left slider 17 and right slide block 10.Left slider 17 and right slide block 10 on base 1 slidably.Be installed with left screw 18 in left slider 17, between the termination of left screw 18 and left slider 17, be provided with adjusting pad 19.Be installed with right screw 11 in right slide block 10, between the termination of right screw 11 and right slide block 10, be provided with equally adjusting pad.Left screw 18 and right screw 11 all with the same filament thick stick 9, match but the rotation direction of screw thread is contrary.One end of leading screw 9 is connected by shaft coupling 6 with the output shaft of motor 7, and motor 7 is fixedly connected with base 1 by Connection Block 8.Be connected with left chuck 16 on left slider 17, be connected with right chuck 12 on right slide block 10.The inboard that left chuck 16 is relative with right chuck 12 is connected with respectively left fixture block 15 and the right folder port 13 of holding workpiece 14, and left fixture block 15 is two and V-shaped distribution, and the opening of V-arrangement is inside; Right fixture block 13 is two and V-shaped distribution, and the opening of V-arrangement is inside.
Vertical hole is arranged on base 1, in this vertical hole, be fitted with column 5.There is jack at the middle part of column 5, and insert in this jack at the middle part of leading screw 9.Leading screw 9 middle parts have 2, two shaft shoulder 2 medial surfaces of two parallel shaft shoulders just to be stuck in the both sides of column 5 jack bottoms, middle part, and there is the concave surface of supporting workpiece 14 upper end of column 5.There is spring 4 lower end of column 5 and the plug 3 that is threaded with base 1 leans.The tank filler sleeve that leads to rubbing surface between column 5 and the shaft shoulder 2 is arranged on column 5.
During work, motor 7 drives leading screw 9 rotations, leading screw 9 drives two screws simultaneously and moves, and because the hand of spiral of two screws is contrary, two screws move in opposite directions, drive two slide blocks and move in opposite directions with respect to base 1, slide block internal fixture block mutually presss from both sides to being positioned at middle shaft-like workpiece 14.Reach the purpose of centering clamping.By adjusting the thickness of axial adjusting pad 19, the position of capable of regulating holding workpiece centering.Before clamping, first workpiece 14 is placed on the concave surface of column 5 upper ends, automatic capturing after clamping, the bottom of column 5 is owing to there being spring 4 to support in quick condition.The axial limiting of leading screw 9 by column 5, with the side of two shaft shoulders 2, coordinated carry out spacing.Overall structure is simple, takes up room little, and accurately, installation and maintenance are convenient, can improve machining quality in centering centering.
