Description
Technical field
The present invention relates to machining technology field, and in particular to a kind of thin walled cylinder body part clamping device.
Background technology
In mechanical processing process, all need to carry out part to be processed one positioning and locking, it is traditional to column work
The clamping of part, it is more that its position is accurately positioned by the way of inner support, due to consideration that the spy of columnar workpiece wall thickness
Sign, it is necessary to assure support force can be only achieved effective positioning to workpiece in uniform, while avoid the damage to workpiece, and traditional
The uniformity for having clamping force using the device of interior support force clamping workpiece cannot be guaranteed, and influence clamping effect, while structure is set
Count complex, be not easy to move integrally installation, poor practicability to device.
The content of the invention
It is an object of the invention to solve above-mentioned technical problem, there is provided a kind of thin walled cylinder body part clamping device, have folder
Tight effect is good, simple operation, structure design simple, easy to install, practicality is stronger the characteristics of.
In order to solve the above technical problems, present invention employs a kind of thin walled cylinder body part clamping device, including pedestal and drive
Dynamic group, wherein, in the driving group axially mounted hole set on the pedestal, the driving group includes swivel nut, spiral shell
Bar, limited block and wedge two, the swivel nut are connected with the screw flight, the screw rod, the limited block and the wedge shape
From top to bottom sequentially it is fixedly connected between the three of block two, the swivel nut and the inwall in the axially mounted hole are slidably matched, and should
The lower end of swivel nut is wedge one, and the both sides of the limited block are axially arranged with stopper slot, on the pedestal set by correspondence position
Bearing pin is slidably matched with the stopper slot；It is horizontal on the pedestal to be provided with upper gripper jaw and lower clamping jaw, one end of the upper gripper jaw with
The wedge one offsets, and one end of the lower clamping jaw offsets with the wedge two, the wedge one and the wedge
The incline direction of two lozenges is on the contrary, the outer end of the upper gripper jaw and the lower clamping jaw is equipped with garter spring.
Further, in above-mentioned technical proposal, the screw rod, the limited block and the three of the wedge two are integral type
Structure.
Further, in above-mentioned technical proposal, the upper gripper jaw is circumferentially evenly arranged with three with the lower clamping jaw.
Further, in above-mentioned technical proposal, it is additionally provided with the pedestal and hole is fixedly mounted.
Beneficial effect possessed by the present invention：Because the lower end of swivel nut is wedge one, wedge shape is realized by rotary threaded sleeve
Block one drives the horizontal movement of upper gripper jaw one, and because swivel nut is connected with screw flight, the drive screw rod that moves down of swivel nut moves up, and realizes wedge
The horizontal movement of the lower clamping jaw of the driving of shape block two, because the extruding force of wedge one and wedge two is equal in magnitude, final realization pair
Uniform clamping above and below workpiece inner wall, there is the characteristics of clamping effect is good, just can be realized pair due to only needing to operate swivel nut
The uniform clamping of workpiece inner wall, there is the characteristics of simple operation, and this structure design is simple, easy to install, practicality is stronger.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
In figure：Pedestal 1；Axially mounted hole 2；Hole 3 is fixedly mounted；Swivel nut 4；Wedge 1；Screw rod 5；Limited block 6；Limit
Position groove 61；Wedge 27；Bearing pin 8；Upper gripper jaw 9；Lower clamping jaw 10；Garter spring 11；Workpiece 12；Supporting bable tops 13.
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 thin walled cylinder body part clamping device, including pedestal 1 and driving group, wherein,
In driving group axially mounted hole 2 set on pedestal 1, it is additionally provided with pedestal 1 and hole 3 is fixedly mounted, driving group includes spiral shell
Set 4, screw rod 5, limited block 6 and wedge 27, swivel nut 4 are threadedly coupled with screw rod 5, screw rod 5, limited block 6 and wedge 273
Person is from top to bottom sequentially designed as integral structure, and swivel nut 4 and the inwall in axially mounted hole 2 are slidably matched, and under the swivel nut 4
Hold as wedge 1, the both sides of limited block 6 are axially arranged with stopper slot 61, the bearing pin 8 on pedestal 1 set by correspondence position with it is spacing
Groove 61 is slidably matched；The horizontal upper gripper jaw 9 that is provided with is evenly arranged with three with lower clamping jaw 10 and the two circumference on pedestal 1, upper gripper jaw 9
One end offseted with wedge 1, one end and the wedge 27 of lower clamping jaw 10 offset, wedge 1 and wedge 27
The incline direction of lozenges is on the contrary, the outer end of upper gripper jaw 9 and lower clamping jaw 10 is equipped with garter spring 11.
Workpiece 12 is placed on the supporting bable tops 13 of pedestal 1, screws swivel nut 4 afterwards, swivel nut 4 moves down, and wedge 1 drives
Dynamic upper gripper jaw 1 realizes the clamping to the upper end of workpiece 12, during swivel nut 4 moves down, passes through the drive of screw rod 5, wedge
27 move up, and realize lower clamping of the clamping jaw 10 to the lower end of workpiece 12, treat the completion of processing of workpiece 12, reversely screw swivel nut 4, on swivel nut 4
Move, wedge 27 moves down, and the enclasping force for compressing disc spring 11 retracts upper gripper jaw 9 and lower clamping jaw 10, and workpiece 12 is released.
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.
