Further, in above-mentioned technical proposal, the skewed slot is T-slot.
Further, in above-mentioned technical proposal, turn is provided between symmetrically arranged lower clamping jaw.
Beneficial effect possessed by the present invention:Due to being moved up and down using push rod drivening rod, the both ends of connecting rod are simultaneously Upper gripper jaw is driven to move up and down, upper gripper jaw is slidably matched with the skewed slot set by pedestal upper end, and upper gripper jaw is during slip It can realize that the clamping to workpiece top inner wall with loosening, descends the design of clamping jaw in addition, realize the clamping to workpiece bottom interior wall With loosening, there is the characteristics of clamping effect is good;The design of compression spring simultaneously, one can be offset during push rod pulls down Point pulling force, prevent expansion block be applied to lower clamping jaw thrust it is excessive, can so as to cause the excessive clamping to workpiece and defective work piece Ensure the quality of workpiece.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
In figure:Pedestal 1;Upper gripper jaw 2;Lower clamping jaw 3;Push rod 4;Connecting rod 5;Expansion block 6;Skewed slot 7;Horizontal through hole 8;Axially extending bore 9;Stop screw 10;Compression spring 11;Fixed plate 12;Follow block 13;Location-plate 14;Pushing block 15;Workpiece 16.
Embodiment
The present invention is further illustrated below in conjunction with the accompanying drawings.
As shown in figure 1, the present invention provides a kind of double acting floating clamping device, including pedestal 1, symmetrically arranged upper gripper jaw 2nd, symmetrically arranged lower clamping jaw 3, push rod 4 and connecting rod 5, wherein, the both sides of the upper end of pedestal 1 are arranged with skewed slot 7, and skewed slot 7 is T-shaped Groove, upper gripper jaw 2 are slidably matched with skewed slot 7 respectively, and the upper end of pedestal 1 is provided with horizontal through hole 8, connecting rod 5 in horizontal through hole 8 and Moved up and down in horizontal through hole 8, the middle part of connecting rod 5 is fixedly connected with the upper end of push rod 4, the both ends of the connecting rod 5 respectively with upper folder Pawl 2 is fixedly connected;The inwall of pushing block 15 set by the upper end of push rod 4 and the axially extending bore 9 set by pedestal 1 is slidably connected, the push rod 4 Middle part be arranged with expansion block 6 and be slidably connected therebetween, workpiece 16 is clamped when the top of pushing block 15 and expansion block 6 offsets, swollen The upper end of block 6 is slidably matched with lower clamping jaw 3, lower clamping jaw 3 located at pedestal 1 middle part and be slidably matched with pedestal 1, lower clamping jaw 3 with Stop screw 10 is provided between pedestal 1;The lower end of expansion block 6 is arranged with compression spring 11, one end and the institute of pedestal 1 of compression spring 11 If spring cavity 12 top connection, the other end is connected with the fixed plate 12 set by the lower end of expansion block 6, fixed plate 12 and axially extending bore 9 inwall is slidably connected, and the push rod 4 of the lower section of expansion block 6 is provided with follow block 13;The top of pedestal 1 is provided with location-plate 14, location-plate 14 are located at the top of axially extending bore 9.Set turn to can help to lower clamping jaw between lower clamping jaw 3 and unclamp workpiece, prevent lower card The situation of clamping stagnation occurs when unclamping workpiece 16 for pawl 3.
Lower pulling-pushing rod 4, the drivening rod 5 of push rod 4 move down in horizontal through hole 8, the both ends of connecting rod 5 respectively with upper gripper jaw 2 are fixedly connected, and directly drive upper gripper jaw 2 along the slide downward of skewed slot 7 located at the upper end of pedestal 1, the process that upper gripper jaw 2 moves down In, its spacing increase being used between the end of stretching workpiece 16, realize the clamping to the upper end inwall of workpiece 16;Push rod 4 moves down During, pushing block 15, which moves down, to be pushed directly on expansion block 6 and moves down, and expansion block 6 realizes lower clamping jaw 3 to the lower end of workpiece 16 during moving down The clamping of inwall, and because compression spring 11 can offset the thrust that part expansion block 6 moves down, effectively avoid the clamping to workpiece 16 Power it is excessive and caused by workpiece 16 damage situation;When needing to loosen workpiece 16, reverse drive push rod 4, on push rod 4 Follow block 13 promotes expansion block 6 upward, and the connecting rod 5 located at the upper end of push rod 4 also drives upper gripper jaw 2 to move up, while realizes and press from both sides Pawl 2 and release of the lower clamping jaw 3 to workpiece 16, workpiece 16 are in relaxation state.
The present invention specification and drawings be considered as it is illustrative and not restrictive, on the basis of the present invention, ability Field technique personnel are according to disclosed technology contents, it is not necessary to which performing creative labour can is made to some of technical characteristics Some are replaced and deformation, within the scope of the present invention.
