Embodiment 1

[0020] A compression mechanism of a flat panel structure according to the present invention, comprising: a compression disc 2, a compression ring 3, a hydraulic system 4, a transmission rod 5 and a pressure plate 6; the transmission rod 5 is connected with the hydraulic system 4, and the hydraulic system 4 can drive the transmission rod 5 moves up and down; one end of the pressing plate 6 is installed on the transmission rod 5, and the other end of the pressing plate 6 is provided with a pressing ring 3; the lower end of the pressing ring 3 is connected with the pressing plate 2.

Embodiment 2

[0022] The hydraulic system 4 drives the transmission rod 5 to move up and down, and adjusts the distance between the pressing plate 6 and the part 1, thereby adjusting the size of the pressing force; the pressing force is transmitted to the pressing plate 2 through the pressing ring 3 provided at the front end of the pressing plate 6, The connection surface between the compression ring 3 and the compression disc 2 is a spherical surface, and the compression ring 3 can be rotated arbitrarily within a certain space angle to ensure that it is self-adaptive to the parts, and the transmission mode of the compression force between the mechanism components is always surface contact ; When the compression ring 3 is no longer free to rotate, the parts are compressed.

[0023] In the present invention, when the pressing ring 3 is not in the normal direction of the surface of the part, the pressing ring can realize self-adaptive rotation during the pressing process, and the surface conta...

Embodiment 3

[0025] When the flat structure is compressed:

[0026] Step 1, according to the size of the part 1 and the machining process plan, adjust the overall position and quantity of the pressing device, and distribute them reasonably around the part.

[0027] Step 2, start the hydraulic system 4, drive the transmission rod 5 to move up and down, and realize the compression and release of the pressure plate 6.

[0028] Step 3, observe that the pressure disc 2 touches the surface of the part until the pressure ring 2 no longer rotates freely, and the hydraulic system 4 is stopped.

Abstract

The invention discloses a plate structural part pressing mechanism. According to the mechanism, plane contact between a pressing device and a structural part can be effectively realized when plate machining structural parts are processed, point contact and line contact are prevented from being pressed, and the part deformation under force caused by the pressing device is effectively eliminated. According to the size of the part and a machining scheme, the position of the pressing device is adjusted, and the pressing device is driven to move up and down by a hydraulic system, so that the pressing and loosening of a pressing plate are realized; pressing force is transferred to the structural part by a pressing ring which is arranged on the front section of the pressing plate, and the pressing ring can freely rotate at the space angle, so that the self adaption with the part is guaranteed, and the transfer mode between the pressing force and the structural part is surface contact. The same surface contact is adopted at the circumference when the structural part is pressed, so that the conditions of pressing, deformation and deviation of the structural part due to point and line contact are eliminated.

Description

technical field [0001] The invention relates to a pressing mechanism for adding structural parts to a flatbed machine, in particular to the problem of preventing parts from being crushed, deformed and shifted during the pressing process of the pressing device. Background technique [0002] The traditional clamping device for adding structural parts to a flatbed machine consists of a pressing plate and screws. This clamping device is easy to disassemble and install, and has a high frequency of use. However, this method has the following defects: [0003] 1. In the traditional compression device, the pressure plate and the parts are often in point contact and line contact, it is difficult to ensure surface contact, and the stress concentration at the contact position is easy to cause the surface of the part to be crushed; [0004] 2. Several compression devices are often placed around the parts. In the traditional way, the compression state of each compression device is very d...
