Abstract
The utility model relates to a centre gripping cylindrical body's mechanical tongs, including motor and lead screw, the motor drives the lead screw rotates, the lead screw divide into first lead screw and second lead screw, first lead screw with the screw thread opposite direction of second lead screw, be connected with first polished rod on the first lead screw, be connected with the second polished rod on the second lead screw, be connected with first holding in hand on the first polished rod, it holds in hand to be connected with the second on the second polished rod. The utility model discloses a two lead screws can form the auto -lock later as the power supply of tongs, centre gripping object for the part of centre gripping is more firm.
Description
Technical field
This utility model is related to a kind of mechanical gripper, more particularly to a kind of mechanical gripper that can clamp cylindrical object.
Background technology
Existing industry mechanical arm hand, by the principle for gripping object, is divided into clamping and adsorbs two big class.Adsorption-type is commonly used
In the crawl plate-shaped body that body surface is smooth, area is larger, be not suitable for clamping cylindrical object.Two clamping type manipulators
Can be divided into swinging and parallel-moving type according to forms of motion.What the opening and closing armrest of translation type finger referred to moves in parallel, this handss
Refer to simple structure, it is adaptable to clamp flat board and cylinder class material, and the radial dimension of change of object does not affect the position in its axle center,
Its theoretical holding error is zero.Therefore there is highly important purposes.
Utility model content
The purpose of this utility model is to provide a kind of mechanical gripper that can clamp cylindrical object, good clamping effect,
It is not susceptible to loosen.
For achieving the above object, the technical scheme taken of the present invention is：A kind of mechanical gripper of clamping cylindrical object, bag
Include motor and leading screw, the motor drives the leading screw to rotate, the leading screw is divided into the first leading screw and the second leading screw, described first
The screw thread of leading screw and second leading screw is in opposite direction；The first polished rod is connected with first leading screw, on second leading screw
Be connected with the second polished rod, be connected with first polished rod it is first-hand grab, be connected with second-hand on second polished rod and grab.
In such scheme, it is described it is first-hand grab to be grabbed with the second-hand be equipped with rubber contact block.
In such scheme, first gear is connected with the motor, is connected with second gear on the leading screw, described first
Gear meshes together with second gear.
The beneficial effects of the utility model:This utility model, as the power source of handgrip, clamps object using two leading screws
Self-locking can be formed later so that the part of clamping is more firm.
Description of the drawings
Fig. 1 is the structural representation of apparatus of the present invention.
In figure：1 motor；The leading screws of 2-1 first；The leading screws of 2-2 second；The polished rods of 3-1 first；The polished rods of 3-2 second；4-1 is first-hand
Grab；4-2 second-hand grabs；5-1 first gears；5-2 second gears.
Specific embodiment
Below in conjunction with the accompanying drawings, technical scheme is described in detail.
As shown in figure 1, apparatus of the present invention include motor 1 and leading screw, first gear 5-1 is connected with the motor 1,
Second gear 5-2 is connected with the leading screw, first gear 5-1 meshes together with second gear 5-2.The motor 1
Drive the leading screw to rotate, the leading screw in this programme is divided into the first leading screw 2-1 and the second leading screw 2-2, the first leading screw 2-1 and
The screw thread of the second leading screw 2-2 is in opposite direction；The first polished rod 3-1, second leading screw are connected with the first leading screw 2-1
The second polished rod 3-2 is connected with 2-2, be connected with the first polished rod 3-1 it is first-hand grab 4-1, connect on the second polished rod 3-2
It is connected to second-hand and grabs 4-2；It is described first-hand to grab 4-1 and the second-hand grabs and be equipped with 4-2 rubber contact block.
When using, motor drive first gear 5-1 rotate, first gear 5-1 due to engaging with second gear 5-2, so as to
Drive leading screw to rotate, and due to the screw thread of the first leading screw 2-1 and the second leading screw 2-2 it is in opposite direction, therefore by the first polished rod 3-1
With the second polished rod 3-2 drive it is first-hand grab 4-1 and second-hand grabs 4-2 and moves towards contrary direction, so as to form mechanical gripper
Opening and closing, grab 4-1 and second-hand grabs and be equipped with 4-2 rubber contact block additionally due to first-hand, rubber has elasticity big, stretches surely
Intensity is high, and tear resistance and electrical insulating property are good, the advantages of wearability and good drought tolerance.When mechanical gripper catches part, electricity
Machine 1 stops, first-hand to grab 4-1 and second-hand grabs 4-2 because the effect of leading screw forms self-locking, drives part movement.
