Description
Technical Field
The utility model relates to an improved invention of a hydraulic machine, in particular to an improved invention of a column lock of a hydraulic machine.
Background
A hydraulic machine is a machine that uses liquid as a working medium to transfer energy to implement various processes. The hydraulic press can be used for forging and forming, correction, press fitting, packing, pressing blocks, pressing plates and the like, however, large impact force exists in the hydraulic process, the existing upright column is connected and fixed with the base and the top seat, if two homodromous threaded nuts are adopted, the upright column still has looseness although having certain anti-loosening performance, and the upright column needs to be screwed down at regular time, so that the operation is very troublesome.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provide a hydraulic machine column lock with a stable structure.
In order to solve the technical problems, the utility model is realized by adopting the following technical scheme: this hydraulic press stand lock, including base, footstock and removal seat, link to each other through four stands between base and the footstock, it can slide from top to bottom to remove the seat and set up on four stands, its characterized in that: the four upright columns are respectively fixedly arranged on the base and the top seat in a penetrating way, the corresponding upright columns are provided with positioning structures positioned on the upper sides of the top seats, each positioning structure comprises a positive thread nut, a negative thread nut and a seam-riding screw, the positive thread nut and the negative thread nut are mutually attached and in threaded connection with the upright columns, the internal diameters of the positive thread nut and the negative thread nut are different, and the corresponding upright columns have matched external diameters and external threads; the external diameter of positive thread nut is the same with the external diameter of reverse thread nut, and is equipped with a screw hole jointly on the adjacent excircle of the two, matches the installation in this screw hole the joint-riding screw.
The upright post is also provided with positioning structures positioned on the upper side and the lower side of the base.
And small holes for screwing are formed in the outer circles of the positive thread nut and the negative thread nut.
The improved hydraulic press column lock has the advantages that the improved hydraulic press column lock adopts the positioning structure formed by mutually matching the positive thread nut, the negative thread nut and the riding screw, the base and the top seat are fixed on the column, the locking effect is very superior, and the structural stability is improved.
Drawings
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
FIG. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a sectional view of the positioning structure of the present invention.
Detailed Description
The drawings show the structure of the utility model, and the details thereof are further described below with reference to the drawings. In the embodiment, the hydraulic press column lock comprises a base 1, a top seat 2 and a moving seat 3, wherein the base 1 is connected with the top seat 2 through four columns 4, the moving seat 3 can be arranged on the four columns 4 in a vertical sliding manner, the four columns 4 are respectively and fixedly arranged on the base 1 and the top seat 2 in a penetrating manner, a positioning structure 5 positioned on the upper side of the top seat 2 is arranged on the corresponding column 4, the positioning structure 5 comprises a positive thread nut 51, a negative thread nut 52 and a seam-riding screw 53, the positive thread nut 51 and the negative thread nut 52 are mutually attached and in threaded connection with the column 4, the internal diameters of the positive thread nut 51 and the negative thread nut 52 are different, and the corresponding column 4 is provided with a matched external diameter and a matched external thread; the outer diameters of the positive thread nut 51 and the negative thread nut 52 are the same, a screw hole is formed in the adjacent outer circles of the positive thread nut and the negative thread nut, and the riding seam screw 53 is installed in the screw hole in a matched mode.
According to the working principle of the utility model, taking the case that the inner diameter of the positive thread nut 51 is larger than that of the negative thread nut 52 as an example, the positive thread nut 51 is firstly screwed into the larger outer diameter of the upright post 4, then the negative thread nut 52 is screwed into the smaller outer diameter of the upright post 4, the positive thread nut 51 is attached to the negative thread nut 52, and then the riding seam screw 53 is screwed into a screw hole formed by the positive thread nut 51 and the negative thread nut 52, so that the two nuts cannot rotate relatively, the anti-loosening performance is greatly improved, and the structural stability is improved.
As a further improved specific embodiment, the positioning structures 5 located at the upper and lower sides of the base 1 are further provided on the column 4, the principle is the same as that of the positioning structure 5 installed at the upper side of the top seat 2, and the positions of the larger outer diameter and the smaller outer diameter of the column 4 can be properly switched and adjusted in order to adapt to the installation of the positive thread nut 51 and the negative thread nut 52 with different inner diameters.
As a further improved embodiment, the outer circles of the positive thread nut 51 and the negative thread nut 52 are provided with small holes 6 for screwing, so that the nuts can be rotated by external force.
As a further improved specific implementation mode, the lower side of the top seat 2 can also be fixed by the positioning structure, or two nuts with threads in the same direction are used for fixing, so that the horizontal position can be conveniently adjusted.
In summary, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
