[0044] A frame longitudinal lining beam pressing device, the pressing device comprises a KBK track 1, a pulley 2 suspended at the lower end of the KBK track 1 and a balancer 3 connected to the lower end of the pulley 2, and also comprises:

[0045] The press fitter assembly 4 is connected to the lower end of the balancer 3;

[0046] The power source assembly 5 drives the press assembly 4 to gradually clamp the joint between the frame longitudinal beam and the frame lining beam to achieve the pressing and forming of the frame longitudinal beam and the frame lining beam.

[0047] Specifically, a frame longitudinal lining beam pressing device comprises a KBK track 1, a pulley 2 is slidably connected to the lower end of the KBK track 1, a balancer 3 is connected to the lower end of the pulley 2, a press assembly 4 is connected to the lower end of the balancer 3, and the frame longitudinal beam and the frame lining beam are pressed together by the press assembly 4.

[0048] The press assembly 4 includes:

[0049] The press body 41 has a U-shaped frame structure;

[0050] A cylinder 42 is vertically mounted on one end of the upper side wall of the press body 41;

[0051] One end of the cylinder 42 is drivingly connected to the lower end of the balancer 3;

[0052] The other end of the cylinder 42 is drivingly connected to an upper pressing block 43;

[0053] A lower pressing block 44 is installed at one end of the lower side wall of the press body 41;

[0054] The upper pressing block 43 and the lower pressing block 44 are parallel to each other and form a clamping space for installing the frame longitudinal beam and the frame lining beam.

[0055] Specifically, the press fitter assembly 4 has a press fitter body 41, which is a U-shaped structure. The press fitter body 41 is provided with a transverse opening, and the opening forms an upper and lower side wall, wherein the main part of the cylinder 42 is fixedly installed at the port of the upper side wall, and the cylinder 42 is a double-acting cylinder. The cylinder 42 outputs force in the upper and lower directions. The upper end of the cylinder 42 is driven and connected to the balancer 3, and the lower end of the cylinder 42 is driven and connected to the upper pressure block 43, which is installed at the port of the lower side wall of the press fitter body 41. The lower pressing block 44 is installed. The upper pressing block 43 and the lower pressing block 44 are used to clamp the frame longitudinal beam and the frame lining beam, that is, a clamping space is formed between the upper pressing block 43 and the lower pressing block 44. The frame workpiece is clamped or loosened by adjusting the size of the clamping space, thereby pressing and forming the frame longitudinal beam and the frame lining beam. Specifically, the lower driving end of the cylinder 42 drives the upper pressing block 43 to move toward the lower pressing block 44, and the upper pressing block 43 gradually approaches the lower pressing block 44 to clamp the frame longitudinal beam and the frame lining beam, and gradually press them together.

[0056] The power source assembly 5 has a gas delivery pipeline 51 and a gas circuit 52;

[0057] Part of the gas delivery pipeline 51 is distributed and installed along the track of KBK track 1;

[0058] The gas circuit 52 is connected between the gas delivery pipeline 51 and the press-fit assembly 4;

[0059] The gas delivery pipeline 51 delivers compressed air and transmits it to the cylinder 42 through the gas path 52 .

[0060] A valve controller 45 is installed on the press body 41;

[0061] The power source assembly 5 is connected or closed to the cylinder 42 through the valve controller 45;

[0062] The gas delivery pipeline 51 delivers compressed air and transmits it to the cylinder 42 through the gas circuit 52 and the valve controller 45 in sequence;

[0063] The cylinder 42 converts the compressed air into power and drives the upper pressing block 43 to move toward the lower pressing block 44 to achieve the pressing and forming of the frame longitudinal beam and the frame lining beam.

[0064] The KBK track 1 and the pulley 2 cooperate to drive the press assembly 4 to form lateral movement;

[0065] The end of the cylinder 42 connected to the balancer 3 is stretched to push the press body 41 downward in the opposite direction;

[0066] One end of the cylinder 42 connected to the balancer 3 contracts to pull the press body 41 to move upward.

[0067] Specifically, the power source component 5 provides power output for the press-fit assembly 4. The power source component 5 has a gas delivery pipeline 51 and an air circuit 52. The gas delivery pipeline 51 delivers compressed air, and the compressed air then enters the cylinder 42 through the air circuit 52. A valve controller 45 is installed on the press-fit body 41. The valve controller 45 is located between the air circuit 52 and the cylinder 42. The valve controller 45 can control the entry of compressed air. The valve controller 45 has multiple sets of valve switches. When the valve is opened, the compressed air delivered by the gas delivery pipeline 51 is first transmitted through the air circuit 52, and then enters the cylinder 42 through the valve controller 45. Because the cylinder 42 is a double-acting cylinder, the valve controller 45 can match the power path of the cylinder 42. When the frame workpiece needs to be pressed , the corresponding valve of the valve controller 45 is opened, the compressed air enters the corresponding cavity of the cylinder 42, and the pressure is converted into power to move the piston. At this time, the lower driving end of the cylinder 42 drives the upper pressure block 43 to move downward, thereby gradually pressing the frame longitudinal beam and the frame together; similarly, when the height of the press-fit assembly 4 needs to be adjusted, the corresponding valve of the valve controller 45 is opened, the compressed air enters the corresponding cavity of the cylinder 42, and the pressure is converted into power to move the piston. At this time, the upper driving end of the cylinder 42 is stretched upward. Since the position of the balancer 3 connected to the cylinder 42 is fixed, the cylinder 42 will push the press-fit assembly 4 connected thereto to move downward in the opposite direction. The downward movement of the press-fit assembly 4 lowers the height, and when the upper driving end of the cylinder 42 contracts, the press-fit assembly 4 moves upward to increase the height.

[0068] When the left and right positions of the press-fit assembly 4 need to be adjusted, the adjustment can be performed by sliding the pulley 2 on the KBK track 1 .

[0069] The specific implementation process is as follows:

[0070] 1. First, place the frame lining beam to be assembled on the frame longitudinal beam;

[0071] 2. Use a steel chisel to overlap the holes of the frame longitudinal beam and the frame lining beam;

[0072] 3. The upper plane of the lower pressing block 44 is in contact with the outer belly surface of the frame longitudinal beam, and the upper pressing block 43 is in contact with the inner belly surface of the frame lining beam. The piston rod of the cylinder 42 is pushed out to form an action force and a reaction force between the upper pressing block 43 and the lower pressing block 44, thereby 100% fitting the frame longitudinal beam and the frame lining beam;

[0073] 4. After the tightening is completed, the piston rod of the cylinder 42 is withdrawn, and the upper pressing block 43 gradually moves away from the lower pressing block 44, and then the assembled frame workpiece can be taken out.

[0074] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
