Description
Technical field
The utility model is related to a kind of double eccentric wheel clamping device, belongs to machining technology field.
Background technology
In mechanical manufacturing technology, very high is required to the clamping of workpiece, in pincers worker clamping process, usually using flat-nose pliers
Clamping is carried out to workpiece, it is fairly simple for the parts fixation that compares specification, for complicated or irregular part flat-nose pliers
Carrying out clamping, just relatively time-consuming and clamping loosely, if parts fixation is insecure, easily occurs what part came off in process
Phenomenon, comes off in the event of part, and the safety to process equipment has great threat, and even, operating personnel will also result in
Injury.If productivity ratio is relatively low in this way for part comparison length and production in enormous quantities, in order to save production cost,
Productivity effect is improved, therefore it is very necessary to design a kind of double eccentric wheel clamping device.
Utility model content
To solve the above problems, the purpose of this utility model is precisely in order to solve above-mentioned the deficiencies in the prior art, this practicality
New purpose is to provide a kind of double eccentric wheel clamping device.
To solve the above problems, the utility model is achieved through the following technical solutions：A kind of double eccentric wheel clamps dress
Put, it is made up of force application rod 1, screw rod 2, bearing pin 3, eccentric wheel 4, clamp body 5, workpiece 6 and positioning cylinder 7；It is characterized in that：
Described clamp body 5 is rectangle, and positioning cylinder 7 is fixedly mounted in its left side You Liangge holes, and its hole is interference with positioning cylinder 7
Coordinate, the right there are two holes, bearing pin 3 is fixedly mounted, its hole is interference fit with bearing pin 3, most right to have an installation nut；Described
Eccentric wheel 4 is installed on bearing pin 3 and on clamp body 5, and mounting hole and the bearing pin 3 of eccentric wheel 4 coordinate for gap；Described screw rod
2 are fixedly mounted on two eccentric wheels 4 through the installation nut on the right of clamp body 5 and the left side.Workpiece is positioned over during work
Between two positioning cylinders and two eccentric wheels, rotation urging bar 1 makes screw rod 2 rotate and retreat, so that workpiece is positioned and pressed
Tightly；When screw rod 2 is retreated to the right, you can unclamp connecting rod workpiece.
The beneficial effects of the utility model are：A kind of double eccentric wheel clamping device, clamping workpiece is fast, accurate, the letter of firm and structure
Single, safe and reliable, easy to operate the advantages of.
Brief description of the drawings
Fig. 1 is a kind of double eccentric wheel clamping device structural representation.
Embodiment
As shown in figure 1, a kind of double eccentric wheel clamping device, it is by positioning key 1, limited block 2, centering machine seat 3, screw rod
4th, right locating piece 5, left-handed nut 6, workpiece 7, left locating piece 8 and right-handed nut 9 constitute；It is characterized in that：Described positioning key 1
It is installed in the locating slot of workbench；Bottom is installed on 3 bottoms of centering machine seat with screw to described limited block 2 into a ladder
In mounting hole, top is installed in the locating slot of screw rod 4 and coordinated for gap；The described left part screw rod of screw rod 4 is right-handed thread,
Right part screw rod is left hand thread；Described left-handed nut 6 is installed in the right part left hand thread of screw rod 4；Described right-handed nut 9
It is installed on the left part right-handed thread of screw rod 4；Described right locating piece 5 is installed on left-handed nut 6 with screw；Determine on a described left side
Position block 8 is installed on right-handed nut 9 with screw；Described workpiece 7 is installed between right locating piece 5 and left locating piece 8.During work
First workpiece is positioned between two locating pieces, the handle of rotary screw 4, so as to drive left and right nut to realize self-centering clamping work
Part.
Above with it is preferable implementation disclose the utility model, so itself and be not used to limit the utility model, it is all to take
With the technical scheme replaced or equivalent transformation is obtained, all fall within protection domain of the present utility model.
