Abstract
The invention provides a kind of gripper, including motor, pipe sleeve, pawl head and driving screw, it is characterised in that is connected at the top of the driving screw with motor, main part is located at the intracavitary of pipe sleeve；The pipe sleeve outer wall sets symmetrical spring, strut, fix bar, chute and slide bar；Sub-screw is set inside the pipe sleeve；The driving screw and sub-screw realize the operation up and down of sub-screw by being rotated to silk.Gripper of the present invention is relatively low to the damage rate of the less sample operation of size.
Description
Technical field
The invention is related to plant equipment, especially a kind of gripper.
Background technology
On automatic production line, it is often necessary to realize workpiece moving between two workbench, gripper is essential
One of equipment.In general gripper is made up of multi link formula, and cylinder promotes main shaft, and driving mechanical pawl separates or closure,
The problems such as control device is backward, wiring is complicated, be easily disturbed, poor reliability be present, this gripper often position inaccurate, spy
It is not to the less product of size；Because not all product is all firm non-friable, always some products are not subject to
Excessive grip, the damage of sample can be caused.
The content of the invention
For prior art produced problem, the present invention proposes following technical scheme：
A kind of gripper, including motor 1, pipe sleeve 2, pawl first 3 and driving screw 4, it is characterised in that the top of driving screw 4
It is connected with motor 1, main part is located at the intracavitary of pipe sleeve 2；The pipe sleeve outer wall 21 sets symmetrical spring 23, strut
22nd, fix bar 26, chute 27 and slide bar 24；The inside of pipe sleeve 2 sets sub-screw 25；The driving screw 4 and sub-screw 25 are logical
Cross the operation up and down that sub-screw 25 is realized to silk rotation.
The inside of motor 1 sets pressure contact 11.
The sub-screw 25 is symmetrical two, is arranged at driving screw both sides.
The sub-screw 25 divides for top half threaded portion 251 and the latter half supporting part 252；The threaded portion 251 around
The rotating shaft 253 that supporting part 252 is fixed in bottom is rotated.
The top of pipe sleeve outer wall 21 is fixed in described one end of spring 23, and the other end is fixed on the top of strut 22.
The bottom of pipe sleeve outer wall 21 is fixed in described one end of fix bar 26, and the other end connects the rotary joint 261 on strut 22.
The slide bar 24 is each passed through chute 27, and the supporting part 252 of sub-screw 25 is fixed in one end, and the other end withstands slide bar 24
And slidably.
Compared with prior art, advantage of the present invention is as follows：
1st, set driving screw and sub-screw to link silk, drive sliding bar to prop up strut, then rotated by rotary joint,
So as to the folding of control claw head, it is easily controlled than compression pump, operation is more stable；
The 2nd, pressure contact is set, by pressure sensitive controlled motor rotary speed and power can be turned, then by a series of
It is dynamic, reach the pressure of control claw head, product can be protected not to be extruded damage；
The 3rd, " screw rod linkage " mode is set, stationkeeping ability is stronger, the particularly suitable less product of operational size.
Brief description of the drawings
Fig. 1 is structural representation when pawl head of the present invention is opened；
Fig. 2 is structural representation when pawl head of the present invention is closed；
Fig. 3 is driving screw of the present invention and sub-screw junction structural representation；
Fig. 4 is structural representation at chute of the present invention.
In figure, including including motor 1, pressure contact 11, pipe sleeve 2, pipe sleeve outer wall 21, strut 22, spring 23, slide bar 24,
Sub-screw 25, threaded portion 251, supporting part 252, rotating shaft 253, fix bar 26, rotary joint 261, chute 27, pawl first 3 and main spiral shell
Bar 4, it is characterised in that the top of driving screw 4 is connected with motor 1, and main part is located at the intracavitary of pipe sleeve 2；It is described that a left side is set
It is right symmetrical and；The inside of pipe sleeve 2 is set；The driving screw 4 and sub-screw 25 to silk rotation by realizing sub-screw 25
Operation up and down.
Embodiment
Embodiment 1
The technical program is further described below with embodiment below in conjunction with the accompanying drawings：
A kind of gripper, including motor, pipe sleeve, pawl head and driving screw, it is characterised in that the driving screw top and motor
It is connected, main part is located at the intracavitary of pipe sleeve；The pipe sleeve outer wall set symmetrical spring, strut, fix bar, chute and
Slide bar；Sub-screw is set inside the pipe sleeve；The driving screw and sub-screw realize the fortune up and down of sub-screw by being rotated to silk
OK；The motor internal sets pressure contact；The sub-screw is symmetrical two, is arranged at driving screw both sides；The secondary spiral shell
Bar is divided into top half threaded portion and the latter half supporting part；The rotating shaft that the threaded portion is fixed on supporting part around bottom is revolved
Turn；The spring one end is fixed on pipe sleeve outer wall top, and the other end is fixed on strut top；Pipe is fixed in described fix bar one end
Outer wall bottom is covered, the other end connects the rotary joint on strut；The slide bar is each passed through chute, and sub-screw branch is fixed in one end
Support part, the other end withstand slide bar and slidably.
Embodiment 2
Normal hydraulic gripper is chosen as blank group, gripper described in embodiment 1 as a control group, carries out different size
Sample crawl experiment.
It can be seen that gripper of the present invention is relatively low to the damage rate of the less sample operation of size.
