Detailed Description

The following describes the embodiments and the operation principle of the present invention in detail with reference to the accompanying drawings.

As shown in fig. 1-5, a hydraulic single-action clamping device for a valve group lathe comprises a base plate 1 and a plurality of movable gaskets 7, wherein the base plate 1 is of a disc-shaped structure, a positioning angle iron 2 is arranged on one side of the base plate 1, an auxiliary cushion block 3 and a plurality of first positioning pins 4 are arranged on the positioning angle iron 2, the first positioning pins 4 penetrate through the auxiliary cushion block 3, a mounting groove 12 is formed in the other side of the base plate 1, a compression embedding claw 5 is arranged in the mounting groove 12, the lower end of the compression embedding claw 5 is connected with a power output mechanism (such as a hydraulic chuck of a machine tool) of the machine tool, a pressure head 6 opposite to the auxiliary cushion block 3 is formed on the compression embedding claw 5, and the movable gaskets 7 are arranged between the pressure head 6 and a product to be processed during production.

As shown in fig. 3, the positioning angle iron 2 is provided with a mounting hole, and the auxiliary cushion block 3 is provided with a mounting shaft 8 matched with the mounting hole.

Referring to fig. 5, a second positioning pin 9 is further disposed at the center of the positioning angle iron 2, and a positioning hole 10 matched with the second positioning pin 9 is disposed at the center of the auxiliary cushion block 3.

In this example, the bottom of the pressing and inserting claw 5 is formed with a supporting step 11, and the supporting step 11 is movably supported on the mounting groove 12.

During production, according to the specification of the valve bank valve body to be produced, the corresponding pressing embedded claw 5 is selected and used, then the pressing embedded claw 5 is fixed on a hydraulic power mechanism of a machine tool, then the auxiliary cushion block 3 is installed on the positioning angle iron 2, the positioning is carried out through the second positioning pin, then the valve bank valve body to be produced is accurately positioned by the first positioning pin 4, then the hydraulic power mechanism is driven to drive the pressing embedded claw 5 to move, finally, the pressing head 6 extrudes the movable gasket 7 to clamp and fix the valve bank valve body to be produced, the clamping is followed by referring to the attached drawing 6, and thread machining can be carried out.
