Abstract

The invention discloses a pressing mechanism for a flat plate structural member, which can effectively realize plane contact between a pressing device and the structural member in the machining process of the flat plate machined structural member, avoid point contact and line contact of the pressing device and effectively eliminate part stress deformation caused by the pressing device. According to the size of the part and the machining process scheme, the position of the pressing device is adjusted, and the pressing device is driven by a hydraulic system to move up and down so as to realize the pressing and loosening of the pressing plate; the pressing force is transmitted to the machine component through a pressing ring arranged on the front section of the pressing plate, the pressing ring can rotate randomly in a space angle, self-adaptation with parts is guaranteed, and the surface contact between the pressing force and the mechanism component is achieved. The periphery of the structural part is in same surface contact in the pressing process, so that the pressure injury, deformation and deviation of the structural part caused by point and line contact are eliminated.

Description

Flat plate structure pressing mechanism
Technical Field
The invention relates to a pressing mechanism of a plate machine and a structural part, in particular to a pressing device for preventing parts from being crushed, deformed and deviated in a pressing process.
Background
The traditional pressing device for adding the structural part to the flat machine consists of a pressing plate and a screw, is easy to disassemble and assemble, and has high use frequency, but the method has the following defects:
1. in a traditional pressing device, a pressing plate and a part are often in point contact and line contact, surface contact is difficult to ensure, stress at the contact position is concentrated, and the surface of the part is easily crushed;
2. a plurality of pressing devices are often arranged around a part, in a traditional mode, the pressing state difference of each pressing device is large, point contact, line contact and surface contact can exist simultaneously, so that the pressing force in all directions is not uniform, the part is finally deviated, and the processing quality is influenced.
Disclosure of Invention
The invention aims to provide a method for preventing deformation, crush damage and offset in the process of pressing a flat plate type machine-added structural part, aiming at the defects of the existing pressing device for the flat plate type machine-added structural part.
The technical scheme of the invention is as follows:
a hold-down mechanism for a sheet structure according to claim 1, comprising: the device comprises a pressing disc, a pressing ring, a hydraulic system, a transmission rod and a pressing plate; the transmission rod is connected with a hydraulic system, and the hydraulic system can drive the transmission rod to move up and down; one end of the pressing plate is arranged on the transmission rod, and the other end of the pressing plate is provided with a pressing ring; the lower end of the compression ring is connected with the compression disc.
The compression ring and the compression disc are of a spherical connecting structure, so that the compression ring and the compression disc are in surface contact.
The pressing disc is in surface contact with the flat plate part.
The pressing method and principle of the pressing mechanism of the invention are as follows: the pressing device is driven by a hydraulic system to move up and down, so that the pressing plate is loosened and pressed; the pressing force is transmitted to the pressing disc through the pressing ring arranged on the front section of the pressing plate, the pressing ring can rotate randomly within a certain space angle, self-adaptation with parts is guaranteed, and the pressing force is always in surface contact with machine components in a transmission mode. The hydraulic system can control the magnitude of the pressing force. The pressing ring can rotate randomly within a certain space angle and is matched with the pressing disc, so that self-adaptive contact with parts is guaranteed, and the pressing force is always in surface contact with machine components in a transmission mode.
Compared with the prior art, the invention has the following positive effects:
1. the pressing device is simple to install and convenient to operate, and the pressing force is not required to be judged and adjusted through experience;
2. the pressing plate can be in surface contact with the part all the time, and the problems of stress concentration and even part crushing and the like caused by point contact and line contact are avoided;
3. the pressing force of each pressing device is uniform and stable, the problem of part deviation can be avoided, and the processing quality is guaranteed.

Detailed Description
The invention is further illustrated with reference to the following figures and examples.
Example 1
The invention relates to a pressing mechanism for a flat plate structural part, which comprises: the device comprises a pressing disc 2, a pressing ring 3, a hydraulic system 4, a transmission rod 5 and a pressing plate 6; the transmission rod 5 is connected with the hydraulic system 4, and the hydraulic system 4 can drive the transmission rod 5 to move up and down; one end of the pressing plate 6 is arranged on the transmission rod 5, and the other end of the pressing plate 6 is provided with the compression ring 3; the lower end of the compression ring 3 is connected with the compression disc 2.
Example 2
The hydraulic system 4 drives the transmission rod 5 to move up and down, and the distance between the pressing plate 6 and the part 1 is adjusted, so that the pressing force is adjusted; the pressing force is transmitted to the pressing disc 2 through the pressing ring 3 arranged at the front end of the pressing plate 6, the connecting surface between the pressing ring 3 and the pressing disc 2 is a spherical surface, the pressing ring 3 rotates randomly within a certain spatial angle, the self-adaption with parts is ensured, and the pressing force is always in surface contact with the mechanical components in a transmission mode; when the compression ring 3 does not rotate freely any more, the part is compressed.
In the invention, when the compression ring 3 is not positioned in the normal direction of the surface of the part, the compression ring can realize self-adaptive rotation in the compression process, and the surface contact state is always kept between the compression disc 2 and the compression ring 3 as well as between the compression disc and the part 1.
Example 3
When the flat plate structural member is compressed:
step one, adjusting the whole position and the number of the pressing devices according to the size of the part 1 and the machining process scheme, and reasonably distributing the pressing devices around the part.
And step two, starting the hydraulic system 4, driving the transmission rod 5 to move up and down, and realizing the compression and the release of the pressure plate 6.
And step three, observing the contact surface of the pressing disc 2 with the part until the pressing ring 2 does not rotate freely any more, and stopping the hydraulic system 4.
