Description

A kind of lever type hydraulic fixture
Technical field
The utility model belongs to clamping tool for machine work technical field, specifically a kind of lever type hydraulic fixture.
Background technology
Fixture is to be used for during machine-building fixing processing object, 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 of workpiece is filled, fixture is all can be described as.Such as weld jig, inspection jig, assembling jig, jig.Wherein lathe Fixture is most commonly seen, is often simply called fixture.When processing workpiece on lathe, chi as defined in drawing is reached for the surface that enables workpiece Very little, geometry and with the technical requirements such as the relative-position error of other surfaces, workpiece must be installed, clipped before processing. Fixture to knife induction element, indexing means, connecting element and clamp body etc. generally by setting element, clamping device, constitute.It is existing Some injection machine clamps are typically all that the replacing or positioning of mould are realized by the dismounting of mechanical structure with the structure that mould is positioned, Therefore disassembling, assembling and replacing mould is inconvenient, and more mold exchange takes considerable time.
Utility model content
The utility model is in view of the shortcomings of the prior art, provide a kind of lever type hydraulic fixture, this kind of hydraulically operated fixture can be fast Fast carries out disassembling operations to fixture, so as to improve the efficiency of die change.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals:A kind of lever liquid Press to be provided with oil-hydraulic cylinder, the oil-hydraulic cylinder on fixture, including chuck body, the body and be provided with plunger shaft, it is described Oil-hydraulic cylinder upper end, which has, is provided with piston body in opening, the plunger shaft, the piston body upper end is fixedly connected with push rod, institute Push rod is stated in the opening, back-moving spring, described body sidewall are provided between the piston body and the oil-hydraulic cylinder The oil inlet connected with the plunger shaft bottom is provided with, the push rod when the piston body is located at the plunger shaft lowest part Upper end, which is higher than to rotate on the oil-hydraulic cylinder, the body, is provided with pressing plate, and the pressing plate side is located above the push rod, position Pressing plate bottom above the push rod is provided with the recess for preventing that pressing plate from colliding with oil-hydraulic cylinder.Passed through using this structure Hydraulic oil is passed through in oil inlet so that piston body is moved up, push rod upper end is withstood pressing plate and moved up, the opposite side of pressing plate, which is pushed, pushes down mould Tool, so that the quick positioning of mould is realized, when needing to unclamp mould, to hydraulic oil pressure release, work of the piston body in back-moving spring Moved down under, pressing plate is no longer influenced by the power of push rod to unclamp mould.
It is described recessed in above-mentioned technical proposal, it is preferred that set fluted on the body below the pressing plate opposite side Spring is vertically arranged with groove, the spring upper end is contacted by spring cup with the pressing plate.Caused using the structure in hydraulic pressure After oily pressure release, the spring causes pressing plate to be returned to initial position, so that more easily more mold exchange.
In above-mentioned technical proposal, it is preferred that the piston body side surface is provided with first annular groove, the first annular groove It is provided with first seal.The sealing between piston body and oil-hydraulic cylinder is caused to improve using the structure.
In above-mentioned technical proposal, it is preferred that the oil-hydraulic cylinder is the cylindrical part that upper end has opening, the cylindrical part Part, which is embedded in the groove of the body, forms plunger shaft, and the cylindrical part side is provided with the second annular groove, second annular Second seal is provided with groove.Facilitate the installation of piston body using the structure, set second seal improve cylindrical part with The sealing of body.
The utility model compared with prior art, has the advantages that:Passed through using this structure logical in oil inlet Enter hydraulic oil so that piston body is moved up, push rod upper end is withstood pressing plate and moved up, the opposite side of pressing plate, which is pushed, pushes down mould, so as to realize The quick positioning of mould, when needing to unclamp mould, to hydraulic oil pressure release, piston body is moved down in the presence of back-moving spring, pressure Plate is no longer influenced by the power of push rod to unclamp mould.
