Abstract

The invention discloses a hydraulic locking device. The hydraulic locking device comprises a clamp body, a sliding pillar, a hydraulic oil hole, a thin-wall sleeve and an oil tank, wherein the sliding pillar is connected to the center of the clamp body in a sleeving manner; a cylindrical through groove is formed in the center of the sliding pillar; the bottom of the sliding pillar is connected with the clamp body through screws; the thin-wall sleeve is arranged between the sliding pillar and the clamp body; the hydraulic oil hole is formed in one side of the bottom of the clamp body; the oil tank is arranged in the clamp body on the outer side of the thin-wall sleeve; the hydraulic oil hole is communicated with the oil tank. According to the hydraulic locking device disclosed by the invention, the operations of loosening, withdrawing, readjusting after a workpiece is mounted, and locking, all of which need to be carried out every time the workpiece is disassembled, can be avoided. The hydraulic locking device is compact in structure, convenient to operate and rapid to act.

Description

A kind of hydraulic locking apparatus
Technical field
The present invention relates to a kind of hydraulic locking apparatus, belong to fixture aiding support technical field.
Background technology
At present, in actual production, because the reasons such as workpiece shapes and clamping force, cutting force, workpiece gravity may make workpiece produce distortion or unstable after clamping, in order to improve install rigidity and the stability of workpiece, often need aiding support be set.But common spiral aiding support draws formula aiding support with pushing away, and operating automation degree is low, and positioning precision is not high yet.
Summary of the invention
Object: in order to overcome the deficiencies in the prior art, the invention provides a kind of hydraulic locking apparatus.
Technical scheme: for solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of hydraulic locking apparatus, comprise clamp body, traveller, hydraulic pressure oilhole, thin-wall sleeve, oil groove, described clamp body center is connected to traveller, and traveller center is provided with cylindrical groove, be connected with clamp body by screw bottom traveller, between traveller and clamp body, be provided with thin-wall sleeve; Described hydraulic pressure oilhole is arranged on side bottom clamp body, and described oil groove is arranged in the clamp body outside thin-wall sleeve, and described hydraulic pressure oilhole and oil groove are connected.
Also comprise spring, described spring is arranged in traveller groove, for absorption surface.
Also comprise adjustment screw, described adjustment screw is arranged on spring, for regulating spring elastic force.
Also comprise block, described block is arranged on traveller groove mouth, for further fixation workpiece.
Also comprise a lid, described lid is arranged on outside clamp body, concrete for further geometrical clamp.
Preferably, oil groove is set to loop configuration.
Beneficial effect: a kind of hydraulic locking apparatus provided by the invention, must unclamp after can avoiding unloading workpiece at every turn, exit, load onto workpiece after adjust again, lock.The design's compact conformation, easy to operate, action is quick.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figure 1, a kind of hydraulic locking apparatus, comprise clamp body 1, traveller 2, hydraulic pressure oilhole 3, thin-wall sleeve 4, oil groove 5, described clamp body 1 center is connected to traveller 2, traveller 2 center is provided with cylindrical groove 6, be connected with clamp body 1 by screw 7 bottom traveller 2, between traveller 2 and clamp body 1, be provided with thin-wall sleeve 4; Described hydraulic pressure oilhole 3 is arranged on side bottom clamp body 1, and described oil groove 5 is arranged in the clamp body 1 outside thin-wall sleeve 4, and described hydraulic pressure oilhole 3 is connected with oil groove 5.
Also comprise spring 8, described spring 8 is arranged in traveller 2 groove, for absorption surface.
Also comprise adjustment screw 9, described adjustment screw 9 is arranged on spring 8, for regulating spring elastic force.
Also comprise block 10, described block 10 is arranged on traveller 2 groove mouth, for further fixation workpiece.
Also comprise a lid 11, described lid 11 is arranged on outside clamp body 1, concrete for further geometrical clamp.
Preferably, oil groove 5 is set to loop configuration.
Specific embodiment is as follows, and traveller relies on spring and absorption surface, and spring force can regulate with screw.Pass into pressure oil by hydraulic pressure oilhole, make thin-wall sleeve lock traveller.The design's compact conformation, easy to operate, action is quick.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
