Description
Technical Field
The utility model relates to the technical field of press machines, in particular to a guide sleeve and an adjusting structure of an eccentric large-table-top four-point press machine.
Background
With the increasing perfection of the structure of the press, the press is required to be higher by some automobile enterprises, and the large-table-top press is more popular in the market. However, the larger the table top is, the more the number of the force application points is increased in order to ensure the precision and the anti-unbalance loading capability of the press, and the force is applied from a single point to a double point and then to a four point. In the case of a four-point force application press, adjusting the synchronization of the four force application points is one of the first tasks that the individual press manufacturers need to solve. But the guide sleeve and the adjusting structure of the existing large-table-top four-point press are not perfect, the adjusting difficulty is high, and the installation and debugging process is long.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a guide sleeve and an adjusting structure of an eccentric large-table-top four-point press, and aims to solve the problem that the four-point press in the prior art is difficult to adjust when four-point calibration is carried out in the installation and debugging process.
In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a big mesa four point press guide pin bushing of eccentric formula and regulation structure, includes adjusts briquetting and guide pin bushing, it has two to adjust the briquetting, distributes in the both sides of guide pin bushing and is connected with the guide pin bushing through first adjusting screw, guide pin bushing upper end border inserts in the position sleeve of crossbeam, it is connected with the crossbeam through second adjusting screw to adjust the briquetting.
Preferably, a gasket is arranged between the guide sleeve and the adjusting pressing block.
Preferably, the border is formed by connecting two sections of circular arc surfaces and two sections of planes, the position sleeve is also formed by connecting two sections of circular arc surfaces and two sections of planes, the plane on the border is closely attached to the plane in the position sleeve, and the circular arc surface on the position sleeve is larger than the circular arc surface on the border.
Compared with the prior art, the utility model has the beneficial effects that: the guide sleeve and the adjusting structure are convenient to process, four guide sleeves can be adjusted, the adjusting range is large, and the synchronization difficulty is reduced; after the synchronous correction is finished, a base plate is arranged between the pressure block and the guide sleeve according to the distance between the pressure block and the guide sleeve, so that the time for next synchronous correction is shortened.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-5, the present invention provides a technical solution: an eccentric four-point press guide sleeve and an adjusting structure with a large table top comprises two adjusting press blocks 3 and two guide sleeves 2, wherein the two adjusting press blocks 3 are distributed on two sides of the guide sleeves 2 and connected with the guide sleeves 2 through first adjusting screws, the edge 21 at the upper end of each guide sleeve 2 is inserted into a positioning sleeve 11 of a cross beam 1, the adjusting press blocks 3 are connected with the cross beam 1 through second adjusting screws, specifically, the edge 21 at the upper end of each guide sleeve 2 is formed by connecting two sections of arc surfaces and two sections of planes, each positioning sleeve 11 is also formed by connecting two sections of arc surfaces and two sections of planes, the planes on the edge 21 are tightly attached to the planes in the positioning sleeves 11, the arc surfaces on the positioning sleeves 11 are larger than the arc surfaces on the edge 21, the processing requirements of the guide sleeves 2 and the adjusting structure are not high, the arc processing is simple and convenient, and the four groups of guide sleeves 2 and the adjusting structure which are arranged on the four-point press can realize that the four guide sleeves 2 can be adjusted, and the adjusting range is larger, so that four-point synchronization can be better adjusted, and the problem of higher adjusting difficulty when the four-point press is adjusted at four points in the installation and debugging process is solved.
Preferably, after the synchronous correction is finished, a backing plate 4 is arranged between the adjusting pressing block 3 and the guide sleeve 2 according to the distance between the adjusting pressing block and the guide sleeve, so that the time for next synchronous correction is shortened.
The working principle is as follows: when in synchronization correction, the second adjusting screw is not screwed, the guide sleeve 2 moves left and right under the extrusion of the first adjusting screw, and the synchronous correction is completed under the mutual adjustment of the four guide sleeves 2; then the second adjusting screw is screwed, the distance from the end face of the guide sleeve 2 adjacent to the adjusting pressing block 3 to the end face of the adjusting pressing block 3 is measured, the backing plate 4 is matched in a fixed mode, and due to the existence of the backing plate 4, after the adjusting pressing block is disassembled, when the adjusting pressing block needs to be installed again, the backing plates 4 with different thicknesses only need to be placed at corresponding positions, and the four-point synchronization effect can be achieved by slightly adjusting.
The guide sleeve 2 and the adjusting structure are convenient to process, four guide sleeves 2 on the four-point press can be adjusted, the adjusting range is large, and the synchronization difficulty is reduced; after the synchronous correction is finished, a backing plate 4 is arranged between the adjusting pressing block 3 and the guide sleeve 2 according to the distance between the adjusting pressing block and the guide sleeve, so that the time for next synchronous correction is shortened.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
