Abstract
The invention relates to a four-claw linkage type gas claw. The four-claw linkage type gas claw comprises a driving air cylinder, a claw palm is fixedly connected to the front end face of the driving air cylinder, and four claw fingers are arranged on the claw palm in the circumferential direction through a rotating shaft in a rotatable manner; a gas claw linkage block is fixedly connected to a cylinder rod of the driving air cylinder, and the surrounding structure of the gas claw linkage block is formed by the four claw fingers; and the gas claw linkage block is hinged to the claw fingers through connecting rods. By means of the technical scheme, the four-claw linkage type gas claw is simple in structure, low in manufacturing cost and short in manufacturing period; and parts in different shapes can be clamped through the four claw fingers, the clamping force is high, and the reliability is high.
Description
Technical field
The invention belongs to clamping device technical field, be specifically related to a kind of four paws coordinated type gas pawl.
Background technology
In automated production, gas pawl is widely used in part gripping transmission, commercially each producer standardization all, but standardized gas pawl can only the part of gripping given shape, for irregular part, needs to customize special gas pawl, production cycle is long, cost is high, gas pawl of the present invention, is designed to reach with Standard Gases pawl identical effect by general cylinder and several part combination, its four paws can gripping difformity part, novel structure, cost is low, and fabrication cycle is short.
Summary of the invention
The present invention is directed to the shortcoming that existing gas pawl can only grasp at given shape part, provide a kind of four paws coordinated type gas pawl, solve the problem that original gas pawl can only grasp at given shape part.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of four paws coordinated type gas pawl, comprise driving cylinder, described driving cylinder front end face is connected with the pawl palm, the circumference that described pawl is slapped is provided with four pawls is referred to by axis of rotation, described driving cylinder cylinder bar is connected with gas pawl linkage block, four described pawls refer to be formed gas pawl linkage block surround structure, and described gas pawl linkage block is referred to by rod hinge connection pawl.
Further, described pawl is slapped four limits and is provided with boss, described boss front is provided with pawl and refers to groove, described pawl refers to by pawl, end refers to that groove matches with the boss of pawl palm, described boss side surfaces and pawl refer to that end is provided with through hole, boss through hole and pawl refer to that end vias coordinates and insert rotating shaft and form revolute pair, the boss spinning movement referring to around pawl palm for making pawl.
Further, the articulated manner of described gas pawl linkage block and connecting rod is connected and fixed by revolute pair.
Further, described pawl refers to that knee is provided with reinforcement, described reinforcement and rod hinge connection, and the articulated manner of reinforcement and connecting rod is connected and fixed by revolute pair.
Further, described reinforcement and pawl refer to be structure as a whole.
Further, described pawl refers to that leading inside is provided with multiple tracks frictional groove, for keeping frictional force during gripping object.
Further, described frictional groove direction and pawl finger direction are that angle is arranged.
The invention has the beneficial effects as follows:
Adopt technical solution of the present invention, structure is simple, low cost of manufacture, and the manufacturing cycle is short, and its four paws can gripping difformity part, and chucking power is strong, and reliability is high.

Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
Shown in Fig. 3, a kind of four paws coordinated type gas pawl, comprise and drive cylinder 1, described driving cylinder 1 front end face is connected with the pawl palm 2, the circumference of the described pawl palm 2 is provided with four pawls rotationally by rotating shaft 6 and refers to 4, described driving cylinder 1 cylinder bar is connected with gas pawl linkage block 3, and four described pawls refer to that 4 form encirclement structure to gas pawl linkage block 3, and described gas pawl linkage block 3 refers to 4 by connecting rod 5 hinge finger.
The described pawl palm 2 four limits are provided with boss, described boss front is provided with pawl and refers to groove, described pawl refers to by pawl, 4 ends refer to that the boss that groove and pawl are slapped on 2 matches, described boss side surfaces and pawl refer to that 4 ends are provided with through hole, boss through hole and pawl refer to that 4 end vias coordinate and insert rotating shaft 6 and form revolute pair, refer to 4 boss spinning movements on the pawl palm 2 for making pawl.
Described gas pawl linkage block 3 is be connected and fixed by revolute pair with the articulated manner of connecting rod 5.
Described pawl refers to that 4 knees are provided with reinforcement 7, and described reinforcement 7 is hinged with connecting rod 5, and reinforcement 7 is be connected and fixed by revolute pair with the articulated manner of connecting rod 5.
Further, with pawl, described reinforcement 7 refers to that 4 are structure as a whole.
Described pawl refers to that 4 leading inside are provided with multiple tracks frictional groove 8, for keeping frictional force during gripping object.
Described frictional groove 8 direction and pawl refer to that 4 directions are that angle is arranged.
Course of action of the present invention and principle:
During crawl, cylinder 1 is driven to ventilate action, promote gas pawl linkage block 3, gas pawl linkage block 3 pulls four pawls to refer to thus Clamp blocks by connecting rod 5, then by the corresponding travel mechanism that this gas pawl end connects, part is moved to assigned address, cylinder 1 is driven to ventilate action, retract gas pawl linkage block 3, linkage block 3 pulls four pawls refer to thus loosen part, for irregular part by connecting rod 5, owing to there being four pawls to refer to 4, adding gripping angle and clamp dynamics accordingly.
