Abstract

The invention provides a hydraulic clamping device for a special-shaped workpiece. The hydraulic clamping device is suitable for machine tools. The hydraulic clamping device is mainly composed of a base, a fixed matrix hydraulic cylinder and a movable matrix hydraulic cylinder. The movable matrix hydraulic cylinder is matched with the base through dovetail grooves, and longitudinally moves on the base through transmission of a lead screw. The matrix hydraulic cylinders are internally provided with single-action piston-type hydraulic rods resetting through springs, hydraulic oil with appropriate pressure is fed into the hydraulic cylinders, the pressure is transmitted to the hydraulic rods, and therefore the hydraulic rods position and clamp the workpiece. Due to the fact that the extension length of each hydraulic rod can be adjusted through hydraulic parts, the clamping range is not constant, and the hydraulic clamping device can clamp the irregular special-shaped workpiece. The process of reserving unnecessary technological structures on the clamped workpiece according to clamping requirements of the workpiece during machining and formulating the related technique is simplified, workpiece materials are saved, the machining technology is simplified, and the machining efficiency is improved.

Description

Special shape workpiece hydraulic clamping device

Technical field

The present invention relates to a kind of hydraulic clamping device for special shape workpiece, be applicable to lathe.

Background technology

In existing jig, all require workpiece to make regular shape and be convenient to clamping, and workpiece need to, according to adding need to reserving unnecessary process structure and formulate allied processes on workpiece of clamping in man-hour, be wasted material and expend man-hour.

Summary of the invention

The present invention is directed to the deficiency of existing jig, a kind of easy hydraulically operated fixture that can directly clamp reliably special shape workpiece is being provided.

Solution of the above problems of the present invention is as follows: this fixture is mainly by base, and fixed matrix hydraulic cylinder and the matrix hydraulic cylinder that moves about form, and the matrix hydraulic cylinder that moves about is joined merga pass screw rod transmission by dovetail groove and base and vertically moved on base.

In matrix hydraulic cylinder, have the single-acting piston type hydraulic stem by spring reset, hydraulic stem plays location and clamping action to workpiece.Because the extension elongation of each hydraulic stem can regulate by hydraulic part, thereby therefore clamping range is not fixed and is clamped irregularly shaped workpiece.

The present invention is by hydraulic pressure transfer clamping force, and the size of clamping force can regulate by hydraulic circuit, and magnitude range that therefore can holding workpiece is wide.

Detailed description of the invention

Below in conjunction with accompanying drawing, working method of the present invention is described further.

As shown in Figure 2 and Figure 3, external screw thread single-action hydraulic cylinder-13 are connected with oil circuit 6,8,11 by screw thread, are used for clamping single action piston bar-5.

The first step: as shown in Figure 1, the matrix hydraulic cylinder that moves about is joined merga pass screw rod by dovetail groove and base and carried out screw thread transmission and vertically move on base, according to the size of required holding workpiece by regulating screw mandrel-1 to determine the openings of sizes of fixture.Use other instruments that special shape workpiece is placed in the middle of fixture, piston rod is released and made each piston rod contact with workpiece outer wall by oil circuit control section to passing into low-pressure hydraulic oil in fixed matrix cylinder body-10.

Second step: as shown in Figure 6, after the first step completes, by hydraulic fitting-7 and oil circuit 6,8,11, interior external screw thread single-action hydraulic cylinder-13 single action piston bar-15 are released to-10 all single action pistons bar-5 in the matrix hydraulic cylinder that is used for being fixedly clamped.Outer oil circuit is strengthened the fixation to single action piston bar-5 by pressure dwelling loop simultaneously.

The 3rd step: as shown in Fig. 5, after second completes, passed into the hydraulic oil of suitable pressure and piston rod is released and is used for locating and clamping work pieces in matrix cylinder body-3 of moving about by hydraulic fitting-2, oil circuit part keeps clamping force by pressure dwelling loop.
