[0016] Figure 3 This is an assembly diagram of the air conditioning pressure plate with the stepped hole expansion section facing downward. DETAILED DESCRIPTION

[0017] Reference Figure 1 The utility model proposes an air-conditioning pressure plate processing equipment, including a base 1, a hydraulic system 2, and a pressure head assembly 3. The base 1 is provided with a groove 11 for adapting to and accommodating the air-conditioning pressure plate. The groove 11 has a first positioning column 12 that can be adapted and plugged into the narrow section of the step hole of the air-conditioning pressure plate located in the groove 11. The hydraulic system 2 drives the connected pressure head assembly 3 to drive the pressure head assembly 3 to move up and down. The pressure head assembly 3 includes a mounting portion 31 fixedly connected to the output end of the hydraulic system 2 and a plurality of pressure heads 32 fixed on the mounting portion 31, wherein the plurality of pressure heads 32 are arranged vertically and distributed in a circular array with the axis of the positioning column as the center.

[0018] The length of the pressure head 32 is greater than the height of the narrow section of the stepped hole on the air-conditioning pressure plate.

[0019] When in use, the air-conditioning pressure plate is placed in the groove 11, and the flared end of the step hole on the air-conditioning pressure plate is arranged upward, and the hydraulic system 2 is started. The hydraulic system 2 drives the pressure head assembly 3 to move downward, and the multiple pressure heads 32 on the pressure head assembly 3 perform tooth pressing on the step surface in the step hole of the air-conditioning pressure plate located in the groove 11. After the air-conditioning aluminum tube is inserted into the step hole, the aluminum tube is stamped in the flared section of the step hole. After deformation, the part of the aluminum tube can extend into the pressing teeth processed and formed by the device, so that the aluminum tube and the pressure plate can be relatively fixed in the circumferential direction of the aluminum tube.

[0020] In addition, the first positioning column 12 can support the inner wall of the narrow section of the stepped hole of the air-conditioning pressure plate to prevent the inner wall of the stepped hole on the air-conditioning pressure plate from being deformed due to the stamping of the pressure head 32, resulting in the problem that the air-conditioning aluminum tube cannot pass through.

[0021] In the above embodiment, when workers place the air-conditioning pressure plate into the groove 11, they must ensure that the flared end of the step hole on the air-conditioning pressure plate faces upward. If it is placed in the opposite direction, the hydraulic system 2 will drive the pressure head 32 in the pressure head assembly 3 to perform tooth pressing on the outer and inner step surfaces of the step hole of the air-conditioning pressure plate, resulting in failure of the air-conditioning pressure plate processing. The staff can distinguish whether the flared end is facing upward by observing the diameter of the step hole, which is not easy to distinguish.

[0022] In order to solve the above-mentioned problems, the processing equipment proposed in the present invention has a second positioning column 13 fixed on the inner bottom wall of the groove 11, wherein the first positioning column 12 is coaxially fixed to the top end of the second positioning column 13, and the second positioning column 13 can be adapted and plugged with the stepped hole expansion section of the air-conditioning pressure plate located in the groove 11.

[0023] Specific reference Figure 2 When the worker places the air-conditioning pressure plate, when the stepped hole expansion section of the air-conditioning pressure plate is placed upward, the second positioning column 13 supports the air-conditioning pressure plate below, and the air-conditioning pressure plate located at the narrow section is located above the groove 11. When the pressure head 32 punches the air-conditioning pressure plate, the second positioning column 13 supports the air-conditioning pressure plate. If the worker places the air-conditioning pressure plate in the opposite direction, please refer to Figure 3 , then the air conditioning pressure plate will completely enter the groove 11, making it convenient for staff to observe.

[0024] In addition, in order to improve the anti-mistake effect, a pressure sensor can also be installed on the bottom wall of the groove 11. The pressure sensor is connected to the control unit signal. The control unit is also connected to an alarm. When the air-conditioning pressure plate completely enters the groove 11, pressure will be applied to the pressure sensor. The pressure sensor transmits the pressure signal to the control unit. The control unit controls the alarm to sound an alarm to remind the staff that the air-conditioning pressure plate is placed in the wrong direction.

[0025] In the above embodiment, in order to facilitate taking the air conditioner pressure plate, avoidance grooves communicating with the groove 11 for taking and placing the air conditioner pressure plate are opened on both sides of the base 1.

[0026] It should be further explained that the processing equipment proposed in the present invention also includes a positioning pin 4 with adjustable length. The positioning pin 4 is vertically installed on the mounting portion 31, and the bottom end of the positioning pin 4 has a positioning surface that can be fitted with the top surface of the base 1. The depth of the punching of the pressure head 32 is adjusted by adjusting the length of the positioning pin 4.

[0027] In the above embodiment, the cross section of the pressing head 32 is rectangular, and the corners of the pressing head 32 are chamfered.

[0028] The cross section of the pressure head 32 may also be in any shape such as a circle or a polygon.

[0029] A vertically arranged guide sleeve is fixed on the base 1 , and a guide column adapted to be matched with the guide sleeve is fixed on the mounting portion 31 .

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
