Abstract
The utility model discloses a synchronous centering and clamping mechanism, which comprises a base, wherein two slider blocks are arranged on the base through a chute, a nut is fixedly arranged in each slider block, two nuts are matched with one screw and the rotation directions of threads are opposite, one end of the screw is connected to an output shaft of a motor, each slider block is connected to a chuck, clamping blocks used for clamping a work piece are arranged on the opposite inner sides of the two chucks. The synchronous centering and clamping mechanism has the advantages of simple integrated structure, small occupied space, accurate centering, convenience for installation and maintenance, and capability of improving the machining quality.
Description
Technical field
The utility model relates to a kind of clamp mechanism, particularly a kind of for mach synchronous centering clamp mechanism.
Background technology
In machined, often need to carry out clamping to workpiece, 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 utility model be 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 utility model, comprise base, on base, by slideway, two slide blocks are installed, in each slide block, be all installed with screw, 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, is all connected with chuck on each slide block, and two relative inner sides of chuck are provided with the fixture block of holding workpiece.
Synchronous centering clamp mechanism of the present utility model, has 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 leading screw middle part, and two shaft shoulder medial surfaces are just 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 being connected with whorl of base; Between screw and slide block, establish axial adjusting pad.
Synchronous centering clamp mechanism of the present utility model, has 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 utility model, during work, driven by motor leading screw rotates, leading screw drives two screws to move simultaneously, because the hand of spiral of two screws is contrary, two screws move in opposite directions, drive two slide blocks to move in opposite directions with respect to base, slide block mutually internal fixture block presss from both sides to being positioned at middle shaft-like workpiece.Reach the object 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 having spring supporting in quick condition.The axial limiting of leading screw by column, coordinated with the side of two shaft shoulders 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.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model specific embodiment.
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.In left slider 17, be installed with left screw 18, between the termination of left screw 18 and left slider 17, be provided with adjusting pad 19.In right slide block 10, be installed with right screw 11, 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 match with the same filament thick stick 9 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.On left slider 17, be connected with left chuck 16, on right slide block 10, be connected with right chuck 12.The inner side 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.
On base 1, there is vertical hole, 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 to be just 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.On column 5, there is the tank filler sleeve that leads to rubbing surface between column 5 and the shaft shoulder 2.
During work, motor 7 drives leading screw 9 to rotate, leading screw 9 drives two screws to move simultaneously, and because the hand of spiral of two screws is contrary, two screws move in opposite directions, drive two slide blocks to move in opposite directions with respect to base 1, slide block mutually internal fixture block presss from both sides to being positioned at middle shaft-like workpiece 14.Reach the object 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, coordinated with the side of two shaft shoulders 2 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.
