Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a CNC machining device with sheet metal positioning function. Background Technology

[0002] The production of display cases and booths requires CNC machining equipment to process large sheets of material, cutting them into panels of the corresponding specifications. A CNC machine tool is an automated device that uses computer programs to control the machine's movement and machining process. Compared to traditional manual machine tools, CNC machine tools offer higher machining accuracy, higher production efficiency, and better machining quality. Their main characteristics include high precision, high efficiency, high automation, and high flexibility.

[0003] Patent document CN218017247U discloses a positioning base for CNC machining centers, including a base plate. Support rods are welded to the four corners of the base plate's bottom. An adjustment mechanism is provided at the bottom of the base plate, and a clamping plate is welded to the top of the adjustment mechanism. A first threaded rod is threaded through the top of the clamping plate, and a clamping plate is rotatably connected to the bottom of the first threaded rod. A controller is fixedly connected to the top of the base plate. This invention solves the problems of existing positioning bases for CNC machining centers, which are often difficult to adjust during use. They cannot adjust the positioning structure according to material specifications, thus limiting the processing and fixing of plates with different specifications, restricting usability. Furthermore, the required material thickness varies, making it impossible to flexibly adjust the clamping height, resulting in poor material clamping and significant inconvenience, thus reducing the applicability of CNC machining centers.

[0004] In the above solution, the CNC machining center needs to rotate the handle to move the threaded rod and chuck to position the material. This operation is relatively complex and requires manual operation around the machine tool. It has a low degree of automation, low work efficiency, and cannot clean up the waste generated after processing, thus polluting the working environment. Therefore, it is necessary to provide a CNC machining device with sheet metal positioning function to solve the shortcomings of the existing technology. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0023] In this embodiment, as Figure 1-2 As shown, the present invention proposes a CNC machining device with sheet metal positioning function, including a machine tool 1, a fixed base 2 at the bottom of the machine tool, a machining platform 3 at the top of the machine tool, negative pressure holes 301 arrayed on the top surface of the machining platform, and several electric push rods 4 on the side of the machining platform for limiting the sheet metal. Horizontal rails 101 are provided on both sides of the machine tool, a movable seat 5 is installed on the horizontal rails and moves along the direction of the horizontal rails, a vertical rail is provided on the top of the movable seat, a main unit 6 is installed on the vertical rails and moves along the direction of the vertical rails, a vertical rail is provided on one side of the main unit, a tool assembly 7 is installed on the vertical rails and moves along the direction of the vertical rails, the main unit is connected to a fixed pipe 9 via a connecting rod 8, one end of a ventilation pipe 10 passes through the fixed pipe towards the sheet metal, and the other end of the ventilation pipe is connected to an exhaust assembly for sucking up waste generated during sheet metal processing.

[0024] In this embodiment, the machine tool is further configured with a negative pressure component connected to a negative pressure hole. Air is drawn in through the negative pressure hole by the negative pressure component, thereby adsorbing the sheet material onto the processing platform. The negative pressure component can be a suction fan and related pipes; this is existing technology and is not shown in the figure.

[0025] In this embodiment, the electric push rod is further configured such that when the top of the electric push rod is retracted, it is lower than the top surface of the processing platform, which facilitates the transport of the sheet material to the processing platform and is thus restricted. When the top of the electric push rod is extended, it is higher than the top surface of the processing platform. At this time, the electric push rod can limit the side of the sheet material, thereby completing the positioning of the sheet material.

[0026] In this embodiment, the processing platform is further configured with a through groove 302 on the side, through which wires can be threaded. One end of the wire is connected to the electric push rod, and the other end of the wire is connected to the CNC component and the operating component, so as to avoid the wires being exposed and mixed, and to prevent the wires from being damaged when handling the board.

[0027] In this embodiment, the movable seat is further provided with dust curtains 501 at both ends. The dust curtains can prevent processing waste from drifting to both sides and thus polluting the processing environment.

[0028] In this embodiment, the movable seat is further configured to have a transparent window 502 on the front, through which the tool assembly can be directly observed to process the sheet metal, thereby reducing losses caused by processing errors.

[0029] In this embodiment, the machine tool is further configured such that a CNC component 11 and an operating component 12 are provided on one side. The CNC component includes a computer and peripheral components, and the operating component includes a bracket 1201, a button 1202 and an alarm 1203. The button and the alarm are installed on the top of the bracket. The alarm can issue an audible and visual alarm when a machining error occurs, thereby reducing the losses caused during machining.

[0030] Example 2:

[0031] In this embodiment, as Figure 1-2As shown, the present invention proposes a CNC machining device with sheet metal positioning function, including a machine tool 1, a fixed base 2 at the bottom of the machine tool, a machining platform 3 at the top of the machine tool, negative pressure holes 301 arrayed on the top surface of the machining platform, and several electric push rods 4 on the side of the machining platform for limiting the sheet metal. Horizontal rails 101 are provided on both sides of the machine tool, a movable seat 5 is installed on the horizontal rails and moves along the direction of the horizontal rails, a vertical rail is provided on the top of the movable seat, a main unit 6 is installed on the vertical rails and moves along the direction of the vertical rails, a vertical rail is provided on one side of the main unit, a tool assembly 7 is installed on the vertical rails and moves along the direction of the vertical rails, the main unit is connected to a fixed pipe 9 via a connecting rod 8, one end of a ventilation pipe 10 passes through the fixed pipe towards the sheet metal, and the other end of the ventilation pipe is connected to an exhaust assembly for sucking up waste generated during sheet metal processing.

[0032] In this example, the moving base, main unit, and tool assembly correspond to horizontal, vertical, and longitudinal movements, respectively, enabling three-axis machining of the sheet metal. This technology is existing and will not be elaborated here. The exhaust assembly can be an exhaust fan, which is not shown in the figure. The exhaust assembly uses pipes to suck up and collect the waste generated during sheet metal processing, which can prevent the waste from scattering and polluting the processing environment and affecting the health of the workers.

[0033] In this embodiment, the machine tool is further configured with a negative pressure component connected to a negative pressure hole. Air is drawn in through the negative pressure hole by the negative pressure component, thereby adsorbing the sheet material onto the processing platform. The negative pressure component can be a suction fan and related pipes; this is existing technology and is not shown in the figure.

[0034] In this embodiment, the electric push rod is further configured such that when the top of the electric push rod is retracted, it is lower than the top surface of the processing platform, which facilitates the transport of the sheet material to the processing platform and is thus restricted. When the top of the electric push rod is extended, it is higher than the top surface of the processing platform. At this time, the electric push rod can limit the side of the sheet material, thereby completing the positioning of the sheet material.

[0035] In this embodiment, the processing platform is further configured with a through groove 302 on the side, through which wires can be threaded. One end of the wire is connected to the electric push rod, and the other end of the wire is connected to the CNC component and the operating component, so as to avoid the wires being exposed and mixed, and to prevent the wires from being damaged when handling the board.

[0036] In this embodiment, the movable seat is further provided with dust curtains 501 at both ends. The dust curtains can prevent processing waste from drifting to both sides and thus polluting the processing environment.

[0037] The working principle of this CNC machining device with sheet positioning function is as follows: the sheet is placed on the top surface of the machining platform, the electric push rod is raised, and the sheet is moved so that the side of the sheet comes into contact with the electric push rod. That is, the electric push rod is used as a support, and the sheet is adsorbed by the negative pressure component. The CNC tool assembly performs three-axis movement machining according to the drawing. At the same time, the exhaust component is used to suck up the waste generated during the sheet machining.
