Description

Hydraulic compressing device
Technical field
The present invention relates to jig technical field, be specifically related to hydraulic compressing device.
Background technology
Need when utilizing machine tool processing workpiece in production to carry out clamping and positioning to workpiece, just can cut workpiece after clamping or the processing and forming of drilling etc., the clamping and positioning of workpiece on lathe mainly relies on jig to carry out clamping and positioning, but current fixture is generally hand-operated clamping, waste time and energy when clamping workpiece, especially, in large batch of processing, the raising of production efficiency is unfavorable for.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned defect, and provide hydraulic compressing device, this device clamps with hydraulic-driven, does not need manual adjustment, and clamping is quick and laborsaving, contributes to enhancing productivity.
The technical scheme that the present invention solves the employing of its technical problem is as follows:
Hydraulic compressing device, comprise hydraulic cylinder, push rod, clamping bar, holder, described holder is made up of base plate and the pole be vertically set on base plate, preferably, base plate and platen face are with screw fastening, screw fastening adjustment for convenience detach, in large production in enormous quantities, as long as make this hydraulic compressing device be fixed on platen face with screw and adjust position for the first time, as long as later clamping workpiece manufactured workpiece is taken off again unprocessed workpiece is placed on pneumatic control switch on this hydraulic compressing device can by Workpiece clamping, convenient and strength-saving, save a large amount of time, hinged with pole top in the middle part of described clamping bar, clamping bar front end is provided with downward protruding briquetting, described push rod front end is provided with opening, clamping bar rear portion shaft to be embedded in push rod opening and to link with push rod is movable with the bearing pin that push rod front end is arranged, clamping bar rear portion shaft corresponding to junction is provided with the waist-shaped hole that bearing pin can be made to slidably reciprocate, described hydraulic cylinder is arranged on base plate corresponding bottom push rod, the output shaft of push rod bottom and hydraulic cylinder links.Placement multiple hydraulic compressing devices that can be symmetrical in lathe work, steadily balanced when making Workpiece clamping, improve the effect of clamping.
Further, described push rod is vertically arranged, and the push rod vertically arranged makes the length of push rod minimum and can control clamping bar to have larger angle of inclination, is convenient to clamping workpiece, reduces the size of the entirety of this hydraulic compressing device.
Further, the projection briquetting surface of described clamping bar front end is provided with anti-skidding band, the waist-shaped hole diameter at clamping bar rear portion coordinates with pin diameter, normality lower clamping bar keeps level, anti-skidding band prevents clamping bar and workpiece generation relative sliding when clamping, improve the reliability of clamping, push rod move up and down bearing pin is slidably reciprocated in waist-shaped hole and control clamping bar with pole hinged place for axle rotates up and down, thus clamping bar front end clamping work pieces.
Further, the external oil supply system of described hydraulic cylinder, oil supply system is provided with gauge tap, multiple hydraulic compressing devices share an oil supply system, gauge tap controls multiple hydraulic compressing devices simultaneously and clamps simultaneously, makes the steady of Workpiece clamping, impels the lifting of clamping effect.
The invention has the beneficial effects as follows: adopt such scheme, easy and simple to handle, save time, hydraulic control compresses more laborsaving, impels the raising of production efficiency.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.
Fig. 1 is structural representation of the present invention.
Wherein: 1 is base plate, 2 is pole, and 3 is clamping bar, and 3.1 is waist-shaped hole, and 4 is push rod, and 5 is hydraulic cylinder, and 6 is bearing pin.
Detailed description of the invention
Hydraulic compressing device as shown in Figure 1, comprise hydraulic cylinder 5, push rod 4, clamping bar 3, with the holder be made up of base plate 1 and pole 2, what pole 2 was vertical is arranged on base plate 1, the middle part of clamping bar 3 and the top of pole 2 hinged, the front end of clamping bar 3 is downward protruding briquetting, set up defences sliding band in protruding briquetting surface, the front end of push rod 4 is hatch frame, the rear portion shaft of clamping bar 3 to be embedded in the opening of push rod 4 and to link with push rod 4 activity with the bearing pin 6 that push rod 4 front end is arranged, the rear portion shaft of the clamping bar 3 that junction is corresponding is provided with the waist-shaped hole 3.1 that bearing pin 6 can be made to slidably reciprocate, waist-shaped hole 3.1 coordinates with bearing pin 6, hydraulic cylinder 5 is arranged on base plate 1 corresponding bottom push rod 4, the bottom of the push rod 4 and output shaft on hydraulic cylinder 5 top links and push rod 4 shaft keeps vertical, the external oil supply system of hydraulic cylinder, oil supply system is provided with gauge tap.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
