Abstract
The utility model relates to a self-locking hydraulic fixture comprising a cylinder body (1), which is characterized in that the fixture further comprises a power mechanism (18), a sealing mechanism (19) and a micromotion switching feeler lever (15), wherein the power mechanism (18) comprises a flange (2), a spring (3), a piston (4), a one-fourth ring (5), a piston rod (6), a briquetting (7), a restoring confirmed rod (14), the spring (3) is connected on the piston (4) and is clamped between the flange (2) and the piston rod (4), the one-fourth ring (5) is corresponding to the piston (4) and the piston rod (6), the briquetting (7) is corresponding to the piston rod (6), one end of the restoring confirmed rod (14) is connected with a micromotion switching feeler lever (15) through screws, and the cylinder body (1) and the piston rod (6) or the piston (4) and the piston rod (6) are sealed through the sealing mechanism (19). Since the fixture adopts the self-locking hydraulic fixture, the original clamping force still can be kept under the condition that a hydraulic pipe for communicating the fixture is exploded, thereby guaranteeing the safety of clamped objects.
Description
Technical field
The utility model relates to a kind of hydraulically operated fixture, particularly a kind of self-locking hydraulically operated fixture.
Background technology
Because of relating to the person and property safety, adopting the occasion of hydraulically operated fixture is first goal condition with safety all.But owing to reasons such as technology, present anchor clamps all can only guarantee safety doing multiple interlocking aspect hydraulic control and the electrical control, and to being communicated with the fluid pressure line of anchor clamps, and high-pressure hose for example is if explosion is just felt simply helpless.
The utility model content
Solve the above-mentioned technical problem that existing hydraulically operated fixture exists, and a kind of self-locking hydraulically operated fixture is provided.
For achieving the above object, the technical solution of the utility model is as follows:
The self-locking hydraulically operated fixture, comprise cylinder body (1), actuating unit (18), sealing mechanism (19), microswitch feeler lever (15), described actuating unit (18) comprises flange (2), spring (3), piston (4), 1/4 ring (5), piston rod (6), briquetting (7), reset and confirm bar (14), spring (3) is connected on the piston (4), is clipped between flange (2) and the piston (4), 1/4 ring (5) and piston (4), piston rod (6) agrees with, briquetting (7) and piston rod (6) agree with, and reset confirm bar (14) one to be connected with microswitch feeler lever (15) with screw, and cylinder body (1) and piston rod (6) and piston (4) and piston rod (6) usefulness sealing mechanism (19) seal.
Sealing mechanism (19) comprises dust ring (8), y-shaped ring (9), O-ring seals (10), T shape Glais ring (11), y-shaped ring (12), O-ring seals (13), cylinder body (1) and piston rod (6) dust ring (8), y-shaped ring (9), T shape Glais ring (11), y-shaped ring (12), O-ring seals (13) sealing, piston (4) and piston rod (6) seal with O-ring seals (10).
Flange (2), spring (3), piston (4), 1/4 ring (5) is axial mirror image symmetry.
The one side that 1/4 ring (5) and piston rod (6) agree with is the inclined-plane.
Beneficial effect:
The utility model can still keep original chucking power owing to adopt the self-locking hydraulic structure under the situation of the fluid pressure line explosion that is communicated with anchor clamps, guarantee the safety of held object.
Description of drawings
Fig. 1 is a structural front view of the present utility model;
Fig. 2 be the utility model E-E to the cutaway view of bowing;
Fig. 3 is a structure side view of the present utility model;
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As Fig. 1, self-locking hydraulically operated fixture shown in Figure 2, comprise cylinder body 1, actuating unit 18, sealing mechanism 19, microswitch feeler lever 15, described actuating unit 18 comprises flange 2, spring 3, piston 4,1/4 ring 5, piston rod 6, briquetting 7 resets and confirms bar 14, spring 3 is connected on the piston 4, be clipped between flange 2 and the piston 4,1/4 ring 5 and piston 4, piston rod 6 agree with, and briquetting 7 and piston rod 6 agree with, resetting confirm bar 14 one is connected with microswitch feeler lever 15 with screw, and cylinder body 1 and piston rod 6 and piston 4 and piston rod 6 usefulness sealing mechanisms 19 seal.
The one side that 1/4 ring 5 and piston rod 6 agree with is the inclined-plane.
As Fig. 2, shown in Figure 3, hydraulically operated fixture will unclamp the object that is held, the hydraulic fluid port of unclamping 17 oil-feeds must be arranged, oil pressure promotes 1/4 ring 5,1/4 ring, 5 inclined-planes separate with the inclined-plane of piston rod 6 and drive that piston rod 6 retraction unclamps the object that is held otherwise under the elastic force of spring 3, and two inclined-planes compress and produce self-lock force and guarantee that anchor clamps are not released.
When stretching out locking action, hydraulic fluid port 17 oil returns are unclamped in 16 oil-feeds of locking hydraulic fluid port, and oil pressure promotes flange 2, spring 3, and piston 4,1/4 rings 5, piston rod 6, briquetting 7 resets and confirms bar 14, and microswitch feeler lever 15 stretches out and produces the coupling mechanism force of clamping object.
When action is unclamped in withdrawal, unclamp hydraulic fluid port 17 oil-feeds, 16 oil returns of locking hydraulic fluid port, oil pressure promotes flange 2, spring 3, piston 4,1/4 rings 5, piston rod 6, briquetting 7 resets and confirms bar 14,15 withdrawals of microswitch feeler lever.
