Abstract
The utility model discloses a kind of hydraulic press mechanisms, including telescopic bar, support base and the briquetting being set to above support base, the through-hole that the pull rod passes through support base is connected to the lower section of briquetting, it further include sliding rail, one end of the briquetting, which is connected on sliding rail, enables briquetting to slide along sliding rail, is provided with the pin one for crossing sliding rail on the sliding rail.The hydraulic press mechanism of the utility model, a rail structure is increased on the basis of existing hydraulic press mechanism, and makes contact bottom surface of the briquetting with sliding rail become line by face contact using pin and contact, since line contact belongs to higher pair in mechanism, face contact belongs to low pair in mechanism, and therefore, line contact is higher than face contact to mechanism accuracy, that is, making the positioning of hydraulic press mechanism more acurrate, stable；In addition, increasing a dust cover structure, pull rod is protected, prevents iron filings etc. from entering gap, extends the service life of entire hydraulic press mechanism.
Description
Technical field
The utility model relates to a kind of frock clamps, and in particular to a kind of hydraulic press mechanism.
Background technique
With the development of science and technology our frock clamps for using are also from traditional manual to semi-automatic and automatic conversion, just
For hold-down mechanism used at present, relatively common be still it is manual and semi-automatic more, certainly, automatic fixture is also increasingly
It is widely used.Due to the diversity of product, all kinds of fixtures also emerge one after another, and technical staff is also constantly innovating, and have reached
The using effect become better and better.It makes discovery from observation, our hydraulic compressing devices used at present generally pass through a limited block
It is dynamic etc. to prevent rotation stop to be limited, but its using effect is not satisfactory, needs often to debug, cause to process it is unstable, significantly
Waste human cost；Also, the setting accuracy of existing hydraulic press mechanism is not high.
Utility model content
The utility model provides a kind of easy to use and accurate, stable hydraulic to overcome the shortcomings of the above technology
Hold-down mechanism.
The utility model overcomes the technical solution used by its technical problem to be:
A kind of hydraulic press mechanism, including telescopic bar, support base and the briquetting being set to above support base, the drawing
The through-hole that bar passes through support base is connected to the lower section of briquetting, further includes sliding rail, one end of the briquetting, which is connected on sliding rail, to be made
Briquetting can be slided along sliding rail, and the pin one for crossing sliding rail is provided on the sliding rail.
The utility model is preferred, and the junction of pull rod is provided with dust cover on the upper surface of the briquetting, can be with
It prevents iron filings etc. from entering the joint gap between briquetting and pull rod, extends service life.
The utility model is preferred, and the upper end of the sliding rail is U-typed opening, can be with since pull rod has fixed length
Briquetting is avoided to skid off when sliding on the slide rail from the U-typed of sliding rail upper end opening.
The utility model is preferred, and the support base includes the upper support seat being mutually integrated and lower support base, the lower branch
Several counterbores are respectively set on support seat and sliding rail.
The utility model is preferred, and the bottom surface of the sliding rail and the bottom surface of support base are located in same level, with convenient
It is fixed in tooling.
The utility model is preferred, and the pull rod is fixedly connected on the lower section of briquetting by pin two.
The beneficial effects of the utility model are:
The hydraulic press mechanism of the utility model increases a sliding rail knot on the basis of existing hydraulic press mechanism
Structure, and make contact bottom surface of the briquetting with sliding rail become line by face contact using pin and contact, since line contact belongs in mechanism
In higher pair, face contact belongs to low pair in mechanism, and therefore, line contact is higher than face contact to mechanism accuracy, that is, so that hydraulic pressure
The positioning of tight mechanism is more acurrate, stablizes；In addition, increasing a dust cover structure, pull rod is protected, prevents iron filings etc. from entering
Gap extends the service life of entire hydraulic press mechanism.

Specific embodiment
The utility model is better understood for the ease of those skilled in the art, in the following with reference to the drawings and specific embodiments to this reality
It is described in further details with novel, following be merely exemplary does not limit the protection scope of the utility model.
As shown in Figure 1-3, a kind of hydraulic press mechanism described in the utility model embodiment, including telescopic bar 7, branch
Support seat 6 and the briquetting 3 being set to above support base, the pull rod 7 pass through the through-hole of support base 6 and are connected to by pin 25
The lower section of briquetting 3.
The utility model improves maximum place and is that the hydraulic press mechanism further includes sliding rail 1, described in the present embodiment
The upper end of sliding rail 1 is U-typed opening, and the U-typed opening that one end of briquetting 3 is connected to sliding rail 1 above enables briquetting 3 sliding along sliding rail
Dynamic, i.e., briquetting 3 is designed to sliding rail limit, and 3 compacted position of briquetting can be made more acurrate；Also, it is provided on the sliding rail 1
The pin 1 for crossing sliding rail, contacts when briquetting 3 slides down on earth with pin 1, forms line contact, and line contacts in mechanism
Belong to higher pair, compared to the face contact for belonging to low pair, accuracy is higher, i.e., so that hydraulic press mechanism is whole more accurate, steady
It is fixed.
Another improved place is, the junction of pull rod 7 is provided with dust cover on the upper surface of the briquetting 3
2, it can prevent iron filings etc. from entering the joint gap between briquetting and pull rod, extend service life.
