[0031] Embodiment 1:

[0032] The plasma cutting machine for the stainless steel decorative panel used in the elevator car decoration provided by the present utility model is used for performing hole cutting operations on the cut stainless steel decorative panels.

[0033] As Figure 1 , 4 shown in the embodiments, the frame 106 is used to mount each component. Among them, to improve the mechanical strength of the frame 106, the frame 106 can be welded from profiles such as angle steel, strip steel, and square tubes.

[0034] The auxiliary loading and unloading assembly is used to load and unload the stainless steel ornaments to be processed. Specifically, the auxiliary loading and unloading assembly includes a plurality of first support plates 102. Each first support plate 102 is used to support the stainless steel ornament plate to be processed. A cross beam 101 is provided at the frame 106. During assembly, both ends of each first support plate 102 are fixedly connected to the cross beam 101 and the frame 106 respectively. Among them, each first support plate 102 is preferably arranged in parallel, and the upper edges of each first support plate 102 are coplanar, so as to ensure that the upper edges of each first support plate 102 can contact the stainless steel ornament plate, so as to ensure that when the stainless steel ornament plate to be processed is placed at the auxiliary loading and unloading assembly, it will not undergo a large deformation due to the action of gravity.

[0035] During loading, the stainless steel ornament plate to be processed is slid in along the upper edges of each first support plate 102, and the position of the stainless steel ornament plate to be processed is finely adjusted so that two adjacent side edges of the stainless steel ornament plate to be processed coincide with the X-axis and Y-axis along which the clamping seat 104 moves respectively. During unloading, the processed stainless steel ornament plate is slid out along each first support plate 102.

[0036] The cutting and positioning assembly is used to lift out the stainless steel ornament plate to be processed placed at the auxiliary loading and unloading assembly and send the stainless steel ornament plate to be processed to the plasma cutting head. Specifically, the cutting and positioning assembly includes a plurality of second support plates 105 and a bottom support 110. The lower part of each second support plate 105 is connected to the bottom support 110. Through the height adjustment mechanism between the bottom support 110 and the frame 106, each second support plate 105 can protrude out of the plane where the upper edges of each first support plate 102 are located along the gap between the first support plates 102, so that the stainless steel ornament plate to be processed is located at a specified position below the plasma cutting head.

[0037] Under the control of the control unit, the plasma cutting head adjustment assembly adjusts the position of the plasma cutting head to complete the cutting of the stainless steel decorative panel to be processed. Specifically, the laser cutting head adjustment assembly includes a cantilever 103 slidably connected to the frame 106. A clamping seat 104 for clamping the plasma cutting head is slidably connected to the cantilever 103. A first driving motor for adjusting the position of the cantilever 103 is provided between the cantilever 103 and the frame 106, and a second driving motor for adjusting the position of the clamping seat 104 is provided between the clamping seat 104 and the cantilever 103. Among them, in order to achieve the accuracy of the actions of the cantilever 103 and the clamping seat 104, the connection between the cantilever 103 and the frame 106 and between the clamping seat 104 and the cantilever 103 is respectively realized by the cooperation of a linear bearing and a linear shaft.

[0038] A number of I / O interfaces are provided at the control unit. The first driving motor, the second driving motor, the height adjustment mechanism, and the plasma cutting head are respectively electrically connected to the corresponding I / O interfaces at the control unit.

[0039] During use, the cutting parameters of the stainless steel decorative panel to be processed are pre-input into the control unit, and the stainless steel decorative panel to be processed is placed at the auxiliary loading and unloading assembly. Press the start switch. After the control unit receives the start signal, the control unit sends a signal to the height adjustment mechanism, and the bottom support 110 is lifted by the height adjustment mechanism. After a certain delay time (such as 10S) to ensure that the action of the height adjustment mechanism is completed, the control unit controls the first driving motor and the second driving motor to execute actions according to the cutting parameters of the stainless steel decorative panel to be processed. When the clamping seat 104 reaches the cutting area, the control unit sends an opening signal to the plasma cutting head to complete the cutting of the stainless steel decorative panel to be processed. After cutting, the control unit moves the clamping seat 104 to the initial position through the first driving motor and the second driving motor, and at the same time sends a signal to the height adjustment mechanism to perform a reverse action. The bottom plate at the cutting positioning assembly drops, and the processed stainless steel decorative panel falls on the upper edges of the first support plates 102. The staff can pull out the processed stainless steel decorative panel along the upper edges of the first support plates 102.

[0040] Among them, the chip of the control unit is a single-chip microcomputer or a PLC programmable controller.

[0041] It can be understood that the function of the control unit depends on the control unit hardware itself and the program installed in the control unit. It should be noted that the writing of the program is based on the above description of the working principle of the plasma cutting machine for the stainless steel decorative panel of the elevator car decoration. Among them, when writing the program, the specific assembly language, the called functions, and the data debugging methods, etc. are all prior arts, and the program installed in the control unit of the present application is not the content protected by this solution.
