[0025] The bottom of the upper base 1 is fixedly connected to the control box of the CNC equipment.

[0026] The upper connector assembly 2 includes an upper connector seat, an upper connecting rod, and a lower connecting rod. The bottom of the upper connector seat 2-1 is connected to the upper base 1. The upper inner side of the upper connector seat 2-1 is provided with an upper connecting rod 2-2 and a lower connecting rod 2-3. The upper connecting rod 2-2 is connected to the upper end of the upper connecting rod 3, and the lower connecting rod 2-3 is connected to the upper end of the lower connecting rod 4.

[0027] The upper connecting rod 3 is a U-shaped frame structure, located at the top of the upper connecting rod 3 and connected to the top of the telescopic rod of the gas strut 5 via a connector.

[0028] The lower connecting rod 4 has a U-shaped frame structure and is sleeved on the outside of the upper connecting rod 3.

[0029] The lower connector assembly 7 includes a lower connector body, an adjusting screw, a plane bearing, a sliding nut, and a screw clip. The bottom of the gas rod 5 is connected to one end of the sliding nut 7-4. The other end of the sliding nut 7-4 is sleeved on the screw of the adjusting screw 7-2. The head of the adjusting screw 7-2 is located above the lower connector body 7-1. The tail of the adjusting screw 7-2 passes through the lower connector body 7-1, through the other end of the sliding nut 7-4, and is connected to the screw clip 7-5. A plane bearing 7-3 is provided between the upper part of the adjusting screw 7-2 and the lower connector body 7-1.

[0030] The bottom of the lower base 8 is fixed to the platform of the machine tool housing.

[0031] The cable tray 6 is located below the lower connecting rod 4. The cable tray 6 contains a cable.

[0032] Adjustment of the lifting arm device of this utility model:

[0033] 1. The force value of the lifting arm needs to be adjusted for control boxes of different weights.

[0034] 2. When the weight of the control box increases, the load-bearing capacity of the lifting arm needs to be increased. Rotate the adjusting screw 7-2 clockwise, and slide the nut 7-4 downward, which will drive the lower end of the air rod 5 downward, and the angle between the air rod 5 and the upper connecting rod 3 will increase.

[0035] 3. When the weight of the control box is reduced, the load-bearing capacity of the lifting arm needs to be reduced. Rotate the adjusting screw 7-2 counterclockwise, and the sliding nut 7-4 moves upward, which drives the lower end of the air rod 5 upward, and the angle between the air rod 5 and the upper connecting rod 3 becomes smaller.

[0036] As shown in Figures 5 and 6, the pneumatic strut 5, serving as the power source for the lifting arm, provides sufficient support to meet the load-bearing requirements. The upper end of the pneumatic strut 5 is connected to the upper connecting rod 3, and the lower end is connected to the sliding nut 7-4 of the lower connector assembly 7. When the lifting arm is lowered, the telescopic rod of the pneumatic strut 5 retracts and shortens; when the lifting arm is raised, the telescopic rod of the pneumatic strut 5 extends and lengthens.

[0037] As shown in Figure 7, the cable enters from the lower base 8, passes through the cable tray 6 and then enters the upper base 1, finally reaching the control box; the concealment of the cable makes the lifting arm look neat and improves safety.

[0038] As shown in Figures 8 and 9, the lifting arm device of this utility model can rotate within a range of 90° to the left and right, and can also be raised and lowered within a range of 40° to the right. Users can conveniently adjust the position of the control box according to actual needs.

[0039] This utility model of a lifting arm device is widely used in CNC equipment with movable control boxes, such as CNC punching machines, CNC bending machines, CNC injection molding machines, and die-casting machines. The lifting arm's load-bearing range is 15-30KG, suitable for control boxes of different weights.
