Problems solved by technology
[0002] The work of traditional machine tools such as lathes and milling machines with three-jaw chucks generally relies on manual clamping. Most of them use a series of operations such as manual fine-tuning of pressure plates, adjustment bolts and compression bolts, which not only increases the labor intensity. Moreover, the required clamping force is very large, and the clamping is often not tight, which cannot ensure the uniformity of the clamping force and hinders the improvement of production efficiency.

Embodiment 1
[0041] Such as figure 1 As shown, the cylinder of the present invention includes two, respectively, a thrust cylinder and a tension cylinder, and a set of fixed mounts are respectively symmetrically fixed on the front and rear sides of the installation base plate, and the thrust cylinder and the tension cylinder are respectively fixed on the two mounts.
[0042] Such as figure 1 As shown, the slide block includes a slide block with holes and two slide blocks without holes. There are three linear guide rails, and the three linear guide rails are evenly distributed at an angle of 120 degrees, and are fixed on the installation base plate. One of them is The linear guide rail is set along the thrust direction of the thrust cylinder, the sliding seat block with holes is installed on the linear guide rail corresponding to the thrust cylinder, and the two sliding seat blocks without holes are installed on the other two linear guide rails (both sides of the pulling cylinder), The jaw...

The invention relates to a pneumatic dual-effect three-jaw linkage device which comprises an installation bottom plate, air cylinders, linear guide rails, sliding base cushion blocks, a rotating discand clamping jaws. The two sides of the installation bottom plate are each provided with one air cylinder, the multiple linear guide rails are arranged on the installation bottom plate, and one ends of the multiple linear guide rails are converged to a clamping center point; each linear guide rail is provided with one sliding base cushion block, and the sliding base cushion blocks are in sliding connection with the linear guide rails; each sliding base cushion block is provided with one clamping jaw, and the multiple sliding base cushion blocks are connected with the rotating disc through connection rods; and the two air cylinders are jointly connected with one sliding base cushion block and apply acting force in the same direction to the corresponding sliding base cushion block. Clampingforce of the clamping jaws is improved, the device structure is simplified, and opening and closing efficiency of the clamping jaws is improved.
Description
technical field [0001] The invention belongs to the technical field of lathe clamps, and in particular relates to a pneumatic double-action three-jaw linkage device. Background technique [0002] The work of traditional machine tools such as lathes and milling machines with three-jaw chucks generally relies on manual clamping. Most of them use a series of operations such as manual fine-tuning of pressure plates, adjustment bolts and compression bolts, which not only increases the labor intensity. Moreover, the required clamping force is very large, and the clamping is often not tight, which cannot ensure the uniformity of the clamping force, which hinders the improvement of production efficiency. Contents of the invention [0003] In order to solve the above problems, the present invention aims at the deficiencies of the prior art, and provides a pneumatic double-action three-jaw linkage device, which increases the clamping force of the jaws, simplifies the structure of th...
