The pneumatic control clamp can clamp a workpiece to be welded, and the workpiece is convenient for workers to perform subsequent welding work after being fixed on the welding platform.

A common pneumatic control clamp consists of a cylinder and a handle. The handle is connected with a piston rod of the cylinder. When a worker manually operates the handle, the piston rod of the air cylinder can extend out or retract, and the function of positioning a workpiece by the aid of the air cylinder pin is achieved. When welding work is required, a worker places a workpiece to be welded on a welding workbench; then the handle is pushed manually to move towards one end close to the cylinder, so that the piston rod of the cylinder is abutted to the workpiece. The effect of clamping the workpiece is realized.

However, in the production line process, a large number of workpieces need to be welded, and workers need to operate frequently. When the manual pneumatic control clamp needs to clamp a workpiece, a worker needs to use a larger thrust to push the handle, so that the workpiece is prevented from being clamped by the clamp in the welding process, and the machined workpiece is low in quality. Repeated work for a long time can increase the labor intensity of the worker.

Detailed Description

The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. The basic principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents and other technical solutions without departing from the spirit and scope of the invention.

It will be understood by those skilled in the art that in the present disclosure, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in a generic and descriptive sense only and not for purposes of limitation, as the terms are used in the description to indicate that the referenced device or element must have the specified orientation, be constructed and operated in the specified orientation, and not for the purposes of limitation.

With reference to the attached drawings 1 to 2 of the specification, a manual pneumatic control clamp according to a preferred embodiment of the present invention is provided. The pneumatically controlled jig includes a clamping member 10 and a drive assembly 20. The clamping member 10 includes a fixed member 11 and a movable member 12. The fixed member 11 is mounted on the welding jig, and the movable member 12 can slide on the fixed member 11 to clamp or release a workpiece placed on the welding jig. The drive assembly 20 is connected to the moveable member 12. A stop plate is arranged on the welding platform, a clamping opening is formed between the stop plate and the clamping end of the movable part 12, and the clamping opening is used for placing workpieces to be welded. The operator can operate the driving assembly 20 to adjust the size of the clamping opening, so as to clamp or loosen the workpiece.

In this embodiment, the clamping member 10 is a cylinder, the fixed member 11 is a cylinder body of the cylinder, and the movable member 12 is a piston rod of the cylinder. The piston rod of the cylinder can be extended or retracted under the action of the drive assembly 20. The end part of a piston rod of the air cylinder is abutted to the workpiece, so that the workpiece is clamped or loosened.

Referring to fig. 3 and 4, the driving assembly 20 includes a support assembly 21 and a force applying member 22. The support assembly 21 is attached to the body of the cylinder. The support assembly 21 includes a connecting plate 211 and a hinge pin 212. The connecting plate 211 is mounted on the cylinder body of the air cylinder, the hinge pin 212 is mounted on the connecting plate 211, and the urging member 22 is rotatably linked on the hinge pin 212. The connecting plate 211 is provided with a yielding hole for the piston rod of the air cylinder to extend out.

In this embodiment, the hinge pin 212 is provided with two, respectively a first hinge pin 2121 and a second hinge pin 2122. Wherein the first hinge pin 2121 is connected to the piston rod of the cylinder and to the force application member 22. The second hinge pin 2122 is fixedly mounted on the connecting plate 211, and the urging member 22 is rotatably connected to the second hinge pin 2122. When the piston rod of the cylinder is in a retracted state, the axis of the urging member 22 is perpendicular to the axis of the cylinder body. When the force applying member 22 rotates around the second hinge pin 2122, the first hinge pin 2121 can be driven to move horizontally, and the first hinge pin 2121 can drive the piston rod of the cylinder to extend or retract. After the workpieces are welded, the worker rotates the force application member 22 in the opposite direction, and the force application member 22 drives the first hinge pin 2121 to move, so that the piston rod of the cylinder is retracted, the workpieces clamped on the welding fixture can be taken down, then the workpieces to be welded are placed on the welding platform, and the workpieces can be welded and the welded workpieces can be taken down through the reciprocating action. In this embodiment, the force applying member 22 is a handle, which is convenient for the operator to hold and operate. The force of the worker rotating the force application member 22 is converted into the thrust of the force application member 22 to the cylinder piston rod, so that the force application magnitude of the rotation is larger than that of the straight line. The arrangement reduces the labor intensity of workers.

Referring to fig. 3 and 4, when the operation space is too small, the force application member 22 rotates about the second hinge pin 2122, and the position occupied by the force application member 22 in the work space is small, which increases the range of use of the mechanism.

The implementation principle of the embodiment is as follows: the worker places the workpiece in the nip between the stop plate and the moveable member 12. The worker rotates the force applying member 22, the force applying member 22 rotates on the second hinge pin 2122, and the force applying member 22 brings the first hinge pin 2121 to move together. After the force application member 22 rotates by a certain angle, the first hinge pin 2121 moves towards one side of the cylinder, so that the piston rod on the cylinder extends out, and at this time, the piston rod of the cylinder can clamp a workpiece placed on the welding fixture. When the worker rotates the force applying member 22 in the opposite direction, the first hinge pin 2121 moves together with the force applying member 22, and the first hinge pin 2121 moves to the side away from the cylinder, so that the piston rod of the cylinder retracts, and the effect of releasing the workpiece is achieved. When the worker of the manual pneumatic control clamp operates, the force application piece 22 is rotated, and the thrust of the force application piece 22 on the piston rod of the air cylinder is greater than the linear thrust, so that the labor intensity of the worker is greatly reduced, and the working efficiency is improved.

It will be appreciated by persons skilled in the art that the embodiments of the invention shown in the foregoing description are given by way of example only and are not limiting of the invention. The objects of the present invention have been fully and effectively accomplished. The functional and structural principles of the present invention have been shown and described in the embodiments without departing from the principles, embodiments of the present invention may have any deformation or modification.
