Problems solved by technology

The general mechanical claw is composed of multi-link type. The cylinder drives the main shaft, which drives the mechanical claw to separate or close. There are problems such as backward control device, complicated wiring, easy to be interfered, and poor reliability. This kind of mechanical claw is often inaccurate in positioning, especially It is for products with small size; since not all products are strong and not fragile, there will always be some products that cannot withstand excessive grip force, which will cause damage to the sample

Embodiment 1

[0021] Below in conjunction with accompanying drawing and specific embodiment the technical scheme is further described as follows:

[0022] A mechanical claw, comprising a motor, a sleeve, a claw head and a main screw, is characterized in that the top of the main screw is connected to the motor, and the main body is located in the cavity of the sleeve; the outer wall of the sleeve is provided with symmetrical springs, A support rod, a fixed rod, a chute and a sliding rod; an auxiliary screw is arranged inside the sleeve; the main screw and the auxiliary screw realize the up and down movement of the auxiliary screw by rotating on the wire; a pressure contact is arranged inside the motor; There are two symmetrical auxiliary screws, which are arranged on both sides of the main screw; the auxiliary screw is divided into an upper half threaded part and a lower half support part; the threaded part rotates around the rotating shaft whose bottom is fixed to the supporting part; One e...

Embodiment 2

[0024] Ordinary hydraulic mechanical claws were selected as a blank group, and the mechanical claws described in Example 1 were used as a control group to carry out grasping tests on samples of different sizes.

[0025]

[0026] It can be seen that the damage rate of the mechanical gripper of the present invention is relatively low when handling samples with small sizes.

Abstract

The invention provides a mechanical claw. The mechanical claw comprises a motor, a pipe casing, a claw head and a main threaded rod and is characterized in that the top of the main threaded rod is connected to the motor, and the main body of the main threaded rod is located in the cavity of the pipe casing; springs, jackstays, fixed links, sliding chutes and sliding bars which are bilaterally symmetrical are arranged on the outer wall of the pipe casing; auxiliary threaded rods are arranged inside the pipe casing; and the up and down operation of the auxiliary threaded rods is realized through the opposite rotation of threads of the main threaded rod and the auxiliary threaded rods. When the mechanical claw is used for operating samples with relatively small sizes, the samples have relatively low damage rate.

Description

technical field [0001] The invention relates to mechanical equipment, especially a mechanical claw. Background technique [0002] In the automatic production line, it is often necessary to realize the movement of the workpiece between the two worktables, and the mechanical claw is one of the indispensable equipment. The general mechanical claw is composed of multi-link type. The cylinder drives the main shaft, which drives the mechanical claw to separate or close. There are problems such as backward control device, complicated wiring, easy to be interfered, and poor reliability. This kind of mechanical claw is often inaccurate in positioning, especially It is for products with small size; since not all products are strong and not fragile, there will always be some products that cannot withstand excessive grip force, which will cause damage to the sample. Contents of the invention [0003] For the problems in the prior art, the present invention proposes the following tech...
