[0002] The controller is the central nervous system of the retarder, and the protective role of the controller housing on the circuit board is crucial. Many precision electrical components are installed on the circuit board. The controller of the existing electric medical bed is equipped with electronic components and circuit boards, and the controller housing needs to be punched, tapped, milled and milled for easy installation. The existing fixture of the controller housing is operated by clamping the controller housing, and the housing will produce high-frequency vibration during processing, resulting in inaccurate processing precision. The controller housing with a special structure is not easy to clamp, and the clamping device used in traditional production uses a pressure plate, a height block and a screw to connect the screw with the screw hole of the tooling table. The torque generated by the connection between the nut and the screw causes the pressure plate to simultaneously press the workpiece and the height block. This type of clamping device is inconvenient when replacing and disassembling the workpiece. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. The embodiments in the basic utility model and all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] according to Figure 1 , Figure 2 and Figure 4 As shown, a controller processing tool for an electric medical bed includes an upper mounting plate 9, a lower mounting plate 10 arranged parallel to the upper mounting plate 9, an adjusting plate 3, and a clamping mechanism 5 for clamping a housing of the controller. The upper mounting plate 9 is connected to the lower mounting plate 10 by a connecting plate 1. A movable window 12 is symmetrically provided in the horizontal and vertical directions on the upper mounting plate 9. A support column 4 for supporting the housing of the controller is provided on the upper mounting plate 9. A bolt 8 is passed through the adjusting plate 3, and the bolt 8 is threadedly connected to the stopper 2 through the movable window 12. The bolt 8 moves along the movable window 12. The window 12 moves axially, and the adjusting plate 3 is pressed against the upper mounting plate 9 by tightening the bolt 8. A sliding clamp 24 is slidably arranged on the adjusting plate 3, and a pneumatic rod 7 is installed on the sliding clamp 24. The clamping mechanism 5 is installed on the upper mounting plate 9 through the moving window 12. The pneumatic rod 7 can support the controller housing to ensure drilling, tapping, milling and other processes on the controller housing. In addition, by arranging multiple adjusting plates 3 and clamping mechanisms 5, the processing part inside the controller housing with a special-shaped structure is supported and clamped to ensure stability during processing.

[0022] The present design supports the processed part inside the controller housing through the pneumatic rod 7, thereby ensuring stability during processing and preventing the support from loosening, and the clamping mechanism 5 is easy to install.

[0023] A support head 6 is arranged on the output end of the pneumatic rod 7. The pneumatic rod 7 drives the support head 6 to move up and down to support the complex structure inside the controller housing, effectively increasing the support contact surface and ensuring the stability of the support. The surface of the support head 6 can also be provided with cross grains to increase friction.

[0024] An adjusting window 11 is axially provided on the adjusting plate 3 , and the sliding clamp 24 is axially slidably arranged in the adjusting window 11 . This structure is conducive to the axial movement of the sliding clamp 24 on the adjusting plate 3 .

[0025] A plurality of sliding clamps 24 are installed in the adjustment window 11 , and multi-point support is achieved through the pneumatic rods 7 on the sliding clamps 24 .

[0026] The cross section of the sliding clamp block 24 is an H-shaped structure. This design can increase the installation area of ​​the pneumatic rod 7.

[0027] A rectangular connecting window 13 is provided on the upper mounting plate 9, and the support column 4 is located at the four corners of the connecting window 13. The air pipe connected to the pneumatic rod 7 is connected to the external cylinder through the connecting window 13. The connecting window 13 can also reduce the weight of the overall device.

[0028] according to Figure 3 As shown, the clamping mechanism 5 includes a tube body 22, a pressure plate 14 and a clamping plate 21. An upper piston 16 and a lower piston 19 are slidably arranged in the tube body 22. The clamping shaft 15 connected to the upper piston 16 extends from the upper end of the tube body 22 to the outside and is connected to the pressure plate 14. The fixed shaft 20 connected to the lower piston 19 extends from the lower end of the tube body 22 to the outside, and the fixed shaft 20 is connected to the clamping plate 21 through the movable window 12. The clamping plate 21 and the tube body are matched by the lower piston 19 in the tube body 22 shrinking inward. The end of the tube body 22 is clamped and fixed on the upper mounting plate 9, and a connection port 18 for supplying or extracting air into the tube body 22 is provided on the middle section of the tube body 22. Air is filled into the tube body 22 through the connection port 18 so that the upper piston 16 and the lower piston 19 diffuse outward to loosen the pressure plate 14 and the clamping plate 21, and the air in the tube body 22 is extracted so that the upper piston 16 and the lower piston 19 shrink toward the center, thereby driving the pressure plate 14 to press down the controller housing, and the clamping plate 21 cooperates with the tube body 22 to clamp the upper mounting plate 9.

[0029] A limiting protrusion 17 is provided in the tube body 22, and the limiting protrusion 17 is directly opposite to the connecting port 18. The limiting protrusion 17 can limit the upper piston 16 and the lower piston 19, ensuring that the upper piston 16 and the lower piston 19 move simultaneously by supplying or exhausting gas into or out of the connecting port 18.

[0030] A clamping ring 23 facing the clamping plate 21 is provided at the end of the tube body 22 . The clamping ring 23 cooperates with the clamping plate 21 to be clamped and fixed on the upper mounting plate 9 . The clamping ring 23 can increase the clamping contact surface with the upper mounting plate 9 .

[0031] Working principle: first adjust the moving position of the adjustment plate 3, tighten the bolt 8 and cooperate with the stopper 2 to press the adjustment plate 3 on the upper mounting plate 9, place the controller housing on the support column 4, and install the clamping mechanism 5 corresponding to the support column 4 on the upper mounting plate 9. At this time, by placing the pressure plate 14 on the controller housing and directly above the support column 4, the other end of the pressure plate 14 is placed on the equal height block, and the cylinder extracts the air in the tube body 22 through the connecting port 18. The upper piston 16 and the lower piston 19 in the tube body 22 are moved toward the center, and the lower piston 19 pulls the clamping plate 21 through the fixed shaft 20 to cooperate with the tube body 22 to be clamped on the upper mounting plate 9. The upper piston 16 pulls the pressure plate 14 through the clamping shaft 15 so that the pressure plate 14 presses the controller housing, adjusts the position of the pneumatic rod 7, and introduces air into the pneumatic rod 7 so that the output end of the pneumatic rod 7 is output outwardly against the surface of the controller housing. The controller housing can be fixed by the clamping mechanism 5 in cooperation with the support point of the pneumatic rod 7 to ensure the stability of the controller housing during processing and avoid vibration of the controller housing.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
