Abstract

The utility model discloses a rotary press plate clamping device which is mainly used for producing bores for circle-shaped work pieces. The rotary press plate clamping device comprises an oil cylinder (1), an oil cylinder piston rod (2) and a clamping body (3). The oil cylinder piston rod (2) is provided with a press plate seat (4). A rotary press plate (5) is moveably connected with the press plate seat (4) through a pin (6). The clamping body (3) is provided with a spring pin assembly (7). The rotary press plate clamping device adopts the structure, the press plate does no need to be disassembled during the clamping and the releasing of work pieces, thereby reducing the labor intensity and improving the work efficiency.

Description

The rotary pressure plate clamping device

Technical field

The utility model relates to a kind of clamping device, especially relates to a kind of rotary pressure plate clamping device.

Background technology

Clamping device is mainly used in the clamping and the location of workpiece, so that workpiece obvious displacement does not take place adding man-hour, thereby improves machining accuracy.Boring processing for the annular workpiece, the anchor clamps that usually need design specialized, these class anchor clamps mainly comprise clamp body and pressing plate etc., when processing work, owing to repeat to clamp, unclamp action, pressing plate needs to dismantle regularly, thereby has expended a large amount of manual labors, not only labour intensity is big, and operating efficiency is also lower.

Summary of the invention

The purpose of this utility model provides a kind of rotary pressure plate clamping device simple in structure, and pressing plate need not be dismantled, and has solved above-mentioned technical problem.

Technical problem to be solved in the utility model is achieved by the following technical solution: it comprises oil cylinder, oil cylinder piston bar and clamp body, the oil cylinder piston bar is provided with the pressing plate seat, rotary pressure plate connects by pin and pressing plate seat are movable, and clamp body is provided with the spring catch assembly.

Rotary pressure plate described in the utility model and workpiece contact position are provided with protuberance, and the horizontal level of clamp body is than the high 0.5mm of horizontal level of workpiece.

The said structure that the utility model adopts is because in the process that workpiece is clamped, unclamps, pressing plate all need not be dismantled, thereby has reduced labour intensity, has improved operating efficiency.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described:

Figure 1 shows that the utility model unclamps the structural representation of work status

Figure 2 shows that the utility model unclamps the vertical view of work status

Figure 3 shows that the structural representation of the utility model clamping work pieces state

Figure 4 shows that the vertical view of the utility model clamping work pieces state

The specific embodiment

By Fig. 1, Fig. 2, Fig. 3 and Fig. 4 as can be known, this kind rotary pressure plate clamping device comprises oil cylinder 1, oil cylinder piston bar 2 and clamp body 3, oil cylinder piston bar 2 is provided with pressing plate seat 4, and rotary pressure plate 5 is by pin 6 and 4 movable connections of pressing plate seat, and clamp body 3 is provided with spring catch assembly 7.Described rotary pressure plate 5 is provided with protuberance 9 with workpiece 8 contact positions, and the horizontal level of clamp body 3 is than the high 0.5mm of horizontal level of workpiece 8.When starting working, oil cylinder piston bar 2 is in and ejects the position, the protuberance 9 of rotary pressure plate 5 is located by the restriction of spring catch assembly 7, the annular workpiece is inserted on the clamp body 3 by pressing plate seat 4, oil cylinder 1 action, 2 withdrawals of oil cylinder piston bar, rotary pressure plate 5 moves to both sides under the pressure of pressing plate seat 4, protuberance 9 until rotary pressure plate 5 clamps with workpiece 8, can implement bore operation to workpiece 8; In the time of need unclamping, oil cylinder 1 action, oil cylinder piston bar 2 ejects, and rotary pressure plate 5 to middle action, can take out the workpiece 8 that processes under the drive of pressing plate seat 4.The utility model is with the described scope of soverlay technique scheme; and the various modification of claim scope and equivalence variation; under the prerequisite that does not depart from technical solution of the present utility model, any modification or improvement that those skilled in the art that the utility model is done realize easily all belong to the utility model scope required for protection.
