Description
Technical field
The utility model relates to mechanical clamp technical field, specially a kind of lever type hydraulic fixture.
Background technique
Fixture is to be used to fix processing object during machine-building, is allowed to occupy correct position, with receive construction or
The device of detection, also known as fixture.In a broad sense, any process in technical process, for rapidly, easily and safely pacifying
The device for filling workpiece, all can be described as fixture.Such as welding fixture, inspection jig, assembling jig, machine tool fixture etc..Wherein lathe
Fixture is most commonly seen, is often simply called fixture.Fixture usually by setting element, clamping device, to knife induction element, indexing means,
The composition such as connecting element and clamp body.Existing clamp structure is complicated, inconvenient for operation, and clamping is not reliable when clamping workpiece,
It takes out time-consuming and laborious when workpiece.
Utility model content
It is mentioned above in the background art to solve the purpose of this utility model is to provide a kind of lever type hydraulic fixture
Clamp structure is complicated currently on the market, inconvenient for operation, and clamping is not reliable when clamping workpiece, time-consuming and laborious when taking out workpiece to ask
Topic.
To achieve the above object, the utility model provides the following technical solutions：A kind of lever type hydraulic fixture, feature exist
In：Including hydraulic cylinder, wedge block, clamp body, spring and two clamping bars；Both ends of the spring is fixedly connected on two clamping bars；
Hydraulic cylinder is fixed on clamp body, and is connected with wedge block one end；
Clamping bar includes rolling pulley, drive rod, support and clamping plate；Drive rod both ends are connected with rolling pulley and clamping plate,
Rolling pulley rolls on the inclined-plane of wedge block, and drive rod is hinged with support, and support is fixedly connected on clamp body.
Preferably, the drive rod and clamping plate articulated connection.
Preferably, the drive rod and clamping plate are detachably connected.
Compared with prior art, the utility model has the beneficial effects that：Using this structure by being passed through liquid in oil inlet
Pressure oil makes piston mobile, and piston rod pushes wedge block to move right, and two idler wheel spacing increase, by the hinged effect of support,
Keep two clamping plates close to each other, realize quick positioning to workpiece, and clamp it is firm, when needing to unclamp workpiece, to hydraulic oil
Pressure release, piston reset, using the physical characteristic of spring, clamping plate is mobile to unclamp workpiece to two sides；
1. rolling pulley, using sliding is rolled, reduces frictional dissipation on wedge block, piece-holder is firm；
2. it is provided with spring between two clamping structures, when needing to take out caught workpiece, using spring return function, time saving province
Power.
Detailed description of the invention
Fig. 1 is the utility model overall structure diagram.
In figure：1, hydraulic cylinder；2, wedge block；3, rolling pulley；4, drive rod；5, support；6, clamp body；7, spring；8,
Clamping plate.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, the utility model provides a kind of technical solution：A kind of lever type hydraulic fixture, including hydraulic cylinder 1,
Wedge block 2, clamp body 6, spring 7 and two clamp systems；7 both ends of spring are fixedly connected on two clamp systems；Hydraulic cylinder 1
It is fixed on clamp body 6, and is connected with 2 one end of wedge block；Clamp system includes rolling pulley 3, drive rod 4, support 5 and clamping plate
8,4 both ends of drive rod are connected with rolling pulley 3 and clamping plate 8, and rolling pulley 3 rolls on the inclined-plane of wedge block 2, drive rod 4 with
Support 5 is hinged, and support 5 is fixedly connected on clamp body 6, and drive rod 4 and clamping plate 8 are articulated and connected, and drive rod 4 and clamping plate 8 are removable
Unload connection, two clamping plates 8 between place caught workpiece.
Working principle：When using this kind of lever type hydraulic fixture, caught workpiece is placed between two clamping plates 8 first, so
Oil plant is entered in hydraulic cylinder 1 by oil inlet afterwards, the piston in hydraulic cylinder by an active force to the right push wedge block 2 to
Right movement, as wedge block 2 moves to right, two rolling pulleies 3 roll on 2 inclined-plane of wedge block, and two rolling pulleies, 3 spacing increases, even
The spring 7 being connected between two drive rods 4 is stretched, and since drive rod 4 and support 5 are articulated connections, two drive rods 4 are in support
It under supporting role, transfers force on the clamping plate 8 of the other end, keeps two clamping plates 8 close to each other to clamp workpiece；When quilt to be unclamped
When pressing from both sides workpiece, stop the input of oil plant in hydraulic cylinder 1, spring 7 is shunk under mechanical characteristic effect, can generate elastic force for drive rod
Part 4 retracts, and the clamping plate 8 positioned at 4 end of drive link is separated from each other, and unclamps caught workpiece, and two rolling pulleies 3 are oblique in wedge block 2
It is rolled on face, two rolling pulleies, 3 spacing reduces, and wedge block 2 moves to left, and makes piston reset；When needing to clamp workpiece again, repeat
This process, here it is the working principles of this kind of hydraulic lever fixture.
Although the utility model is described in detail with reference to the foregoing embodiments, come for those skilled in the art
Say, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic into
Row equivalent replacement, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should all
It is included within the scope of protection of this utility model.
