Handgrip.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of high-accuracy mechanical handgrip, including branch
Frame, driving device, interconnecting piece, clamping limb and controller, the driving device and the interconnecting piece are each attached on the bracket,
The clamping limb includes the first clamping limb and the second clamping limb, first clamping limb and second clamping limb with the company
Socket part is slidably matched, and the glide direction of first clamping limb and second clamping limb is parallel to each other, the driving device with
First clamping limb, second clamping limb connection, drive first clamping limb and second clamping limb movement, the control
Device and the driving device communication connection control the driving device movement.
A kind of above-mentioned high-accuracy mechanical handgrip, the clamping limb are arranged two groups, clamping limb described in two groups with the drive
Dynamic device connection, keeps synchronization action.
A kind of above-mentioned high-accuracy mechanical handgrip, further includes transmission shaft, is fixed with gear on the transmission shaft, and described first
The part that is slidably matched of clamping limb is located at the upper that is slidably matched of second clamping limb, and the first clamping limb sliding is matched
It closes section bottom and second clamping limb atop part that is slidably matched and is equipped with rack gear, the gear is simultaneously with described first
Clamping limb be slidably matched section bottom rack gear and second clamping limb be slidably matched atop part rack gear cooperation, it is described
Transmission shaft is also connect with the driving device.
A kind of above-mentioned high-accuracy mechanical handgrip, the driving device include driving motor and retarder, the driving electricity
Machine is stepper motor.
A kind of above-mentioned high-accuracy mechanical handgrip is additionally provided with mounting portion on the bracket.
The utility model has the following advantages that and high-lighting effect compared with prior art:
The utility model has the beneficial effects that the utility model use controller control driving device provided for clamping limb it is dynamic
Power can be accurately controlled the movement of clamping limb, and using the kind of drive of rack-and-pinion, transmission process precision is high, make
It obtains entire mechanical gripper and possesses good homework precision, increase the clamping of clamping limb by using retarder and rack pinion
Power, suitable for the clamping to large heavy workpiece, clamping effect is stablized.

Specific embodiment
A kind of high-accuracy mechanical handgrip, including bracket 1, driving device, interconnecting piece 5, clamping limb and controller, the driving
Device and the interconnecting piece 5 are each attached on the bracket 1, and the clamping limb includes the first clamping limb 6 and the second clamping limb 7,
First clamping limb 6 and second clamping limb 7 are slidably matched with the interconnecting piece 5, first clamping limb 6 and described
The glide direction of second clamping limb 7 is parallel to each other, and the driving device is connect with the first clamping limb 6, second clamping limb 7,
First clamping limb 6 and second clamping limb 7 is driven to move, the controller and the driving device communication connection, control
Make the driving device movement.
Further, the clamping limb is arranged two groups, and clamping limb described in two groups is connect with the driving device, keeps same
Step movement.
Further, further include transmission shaft 8, gear, the sliding of first clamping limb 6 are fixed on the transmission shaft 8
Mating part is located at the upper that is slidably matched of second clamping limb 7, and first clamping limb 6 is slidably matched section bottom
And second clamping limb 7 atop part that is slidably matched is equipped with rack gear, the gear is sliding with first clamping limb 6 simultaneously
The rack gear and second clamping limb 7 of dynamic mating part bottom are slidably matched the rack gear cooperation of atop part, the transmission shaft 8
Also it is connect with the driving device.
Further, the driving device includes driving motor 3 and retarder 4, and the driving motor 3 is stepper motor.
Further, it is additionally provided with mounting portion 2 on the bracket 1, the installation for mechanical gripper is fixed.
When utility model works, controller controls driving motor 3 and rotates, and is driven by retarder 4 and transmission shaft 8, band
Dynamic first clamping limb 6 and the movement of the second clamping limb 7, when transmission shaft 8 rotates, the first clamping limb 6 is slidably matched the rack gear on part
With the second clamping limb 7 be slidably matched force direction that the rack gear on part is given by gear on the contrary, therefore the first clamping limb 6 and
The direction of motion of second clamping limb 7 is always rotated forward and is rotated backward on the contrary, controlling driving motor 3 by controller, can be with
Realize the operation that is grabbed and unclamped to object, it, can be to object when the first clamping limb 6 and the second clamping limb 7 move toward one another
Body is grabbed, and when the first clamping limb 6 and the second 7 back movement of clamping limb, can unclamp the object of crawl, due to using control
Device control driving motor 3 processed rotates, and driving motor 3 is stepper motor, and driving device has very high precision, transmission process
By the way of rack-and-pinion, the precision in transmission process ensure that, entire mechanical gripper is made to possess good homework precision.
