A kind of clamp quick positioning mechanism
The utility model relates to field of fixtures, particularly relates to the quick positioning mechanism of a kind of clamp pincers.
In modern mechanical manufacturing especially in digital control processing, flat-nose pliers is absolutely necessary.Clamping workpiece is fixed by it, thus is conducive to numerically controlled lathe and carries out accurate machining to workpiece.Traditional flat-nose pliers is when clamping work pieces, mostly utilize the rotation of flat-nose pliers screw mandrel to promote the motion of flat-nose pliers jaw, thus clamping work pieces, when the flat-nose pliers of this kind of structure operates, labor strength is large, need larger strength rotary screw rod, so just cause Workpiece clamping not steadily, clamp unstable problem.
Existing flat-nose pliers increases power set (cylinder, hydraulic cylinder or electric cylinder etc.) replace screw mandrel, thus while reducing the labour intensity of workman, allow flat-nose pliers clamping work pieces fast, improve operating efficiency, but due on the fixed installation caliper of power set and flat-nose pliers main body or caliper tail end fixed position, the position of the main body of power set and flat-nose pliers is relatively-stationary, just make the scope of activities of the moving jaw of flat-nose pliers limited, the workpiece size scope of gripping is also very narrow, thus the usage range of flat-nose pliers is diminished, again because cylinder does not have adjustable detent mechanism, can not according to the position of the workpiece adjusting cylinders of different size, workpiece likely damages because clamping obtains tension, press from both sides too loose to make again in workpiece process unstable, thus the stability of the clamping of workpiece cannot be guaranteed.

The purpose of this utility model is that proposing one can increase clamp clamping scope, increases the clamp quick positioning mechanism of clamp clamping stability.
For reaching this object, the utility model by the following technical solutions:
A kind of clamp quick positioning mechanism, comprise control box, handle, alignment pin and locating hole, described control box is fixedly connected on the power set of clamp, the first end of described handle is vertically connected with the first end of described alignment pin, second end of described alignment pin stretches out from the bottom surface of described control box, and match with described locating hole, described locating hole is arranged on the clamp base corresponding with described alignment pin extended position.
Illustrate further, the clutch end of described power set is connected to clamp moving jaw, and the clutch end of described power set is fixed on the body of clamp by alignment pin and locating hole cooperation.
Illustrate further, described locating hole has multiple, is arranged on clamp base along moving jaw glide direction.
Illustrate further, described alignment pin and described locating hole are close-fitting.
Illustrate further, described operating grip can drive described alignment pin to move along the assembling of described alignment pin and described locating hole and detaching direction.
Illustrate further, described control box can be arranged many group handles and alignment pin.
The utility model is according to the above, power set are not fixed in the constant structure of opposed jaws position base, but can move on base under the drive of detent mechanism, fixing mode is located again and base is fixed by detent mechanism and base, from making, the structure stating clamp is more flexible, adds frock scope and the stability of clamp.

Wherein: base 1, regular jaw 2, moving jaw 3, ears holder 4, pin 5, power set 6, control box 7, handle 8, alignment pin 9, locating hole 10, operating surface 72, groove 101, slide rail 102, clutch end 602, connecting rod 601, the first end 81 of handle 8, second end 82 of handle 8, the first end 91 of alignment pin 9, the second end 92 of alignment pin 9.
Detailed description of the invention
The technical solution of the utility model is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, a kind of clamp quick positioning mechanism, comprise control box 7, handle 8, alignment pin 9 and locating hole 10, described control box 7 is fixedly connected on the power set 6 of clamp, the first end 81 of described handle 8 is vertically connected with the first end 91 of described alignment pin 9, second end 92 of described alignment pin 9 stretches out from the bottom surface of described control box 7, and matches with described locating hole 10, and described locating hole 10 is arranged on the clamp base 1 corresponding with described alignment pin 9 extended position.
Described power set 6 are not fixed in the constant structure of opposed jaws position base, but can move on described base 1 under the drive of described detent mechanism, fixing mode is located again fixing with base 1 by described detent mechanism and base 1, from making, the structure of described clamp is more flexible, the scope of clamping is can according to treating that the size of clamping workpiece carries out regulating, thus ensure that in clamping workpiece process the wild effect that there will not be clamping tension or pine excessively.
The clutch end 602 of described power set 6 is connected to clamp moving jaw 3, and the clutch end 602 of described power set 6 is fixed on the body of clamp by alignment pin 9 and locating hole 10 cooperation.
Described power set 6 afterbody is fixed on clamp base 1, clutch end 602 is flexible under self power drives, drive described moving jaw 3, described moving jaw 3 is slidably connected on described base 1, thus make the two ends of described power set 6 make to fix relative to described clamp entirety, thus described clamp is made to realize stablizing clamping under the driving of described power set 6.
Described locating hole 10 has multiple, is arranged on clamp base 1 along moving jaw 3 glide direction.
Because treat that the workpiece size of clamping differs, if do not change the installation site of described power set 6 according to workpiece size, the workpiece clamp after clamping can be made to obtain tension or excessively loose, even at all can not clamping, arranging multiple described movable span 10 just can allow described power set 6 fixed position more diversified, thus is applicable to the workpiece of the more different sizes of clamping.
Described alignment pin 9 and described locating hole 10 are close-fitting.
During described clamp dress workpiece, described power set 6 outputting power also can receive very large reaction force simultaneously, described alignment pin 9 and described locating hole 10 closely cooperate, described power set and described base 1 can be made to connect into as a whole, thus offset a part of active force, thus power set 6 stable when ensure that clamping.
Described operating grip 8 can drive described alignment pin 9 to move along the assembling of described alignment pin 9 and described locating hole 10 and detaching direction.
Described alignment pin 9 is coordinate closely with described locating hole 10, making it assemble with being separated is need certain strength, when sliding power device 6, there is no good operating position, be easy to operator is scratched on clamp, control box 7 is set up a handle 8 that can operate alignment pin 9 and move, facilitates the operation of whole position fixing process.
Described control box 7 can be arranged many group handles 8 and alignment pin 9.
Described power set 6 are according to the design of different clamp, diverse location can be arranged on, described control box 7 arranges multiple difference coordinate the alignment pin 8 in direction and coordinate the handle 8 of its operation, thus adapt to different clamping mechanisms, by described power set 6 stable position, thus make described power set 6 can on clamp steady operation.
Below know-why of the present utility model is described in conjunction with specific embodiments.These describe just in order to explain principle of the present utility model, and can not be interpreted as the restriction to the utility model protection domain by any way.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other detailed description of the invention of the present utility model, and these modes all will fall within protection domain of the present utility model.
