Description

Technical Field

[0001] This utility model relates to the field of vacuum adsorption workbench technology, specifically a vacuum adsorption workbench for a miniature CNC engraving machine. Background Technology

[0002] A miniature CNC engraving machine is a small-scale CNC engraving device. It mainly consists of three parts: a computer system, a controller, and the engraving main unit. During operation, a vacuum suction worktable is used to limit the workpiece. This worktable is a device that uses vacuum suction to fix the engraving material and typically consists of a worktable surface, vacuum pipes, a vacuum pump, and a control system. The worktable surface is generally made of aluminum alloy or stainless steel, with a precision-machined surface and evenly distributed suction holes. Vacuum pipes connect the worktable surface and the vacuum pump to transmit the vacuum suction.

[0003] However, existing vacuum adsorption stages are prone to producing a large amount of debris on their surface during engraving machine processing, which is inconvenient to clean and thus affects the vacuum adsorption effect. Utility Model Content

[0004] The purpose of this invention is to provide a vacuum adsorption worktable for a micro CNC engraving machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vacuum adsorption worktable for a micro CNC engraving machine, comprising a worktable body and a cleaning component. An adsorption block is installed on the inner side of the worktable body. The cleaning component for cleaning the worktable surface is located at the upper end of the worktable body and includes a dust collection box, a dust collection chamber, a cleaning brush, an exhaust pipe, and a connecting air pipe. The dust collection box has a dust collection chamber inside, and a cleaning brush is installed in the middle of the dust collection chamber. An exhaust pipe is installed at the upper end of the dust collection box, and a connecting air pipe is connected to the left side of the exhaust pipe.

[0006] Furthermore, the side of the platform is provided with a moving component for controlling the movement of the dust collection box, and two sets of the moving component are symmetrically arranged about the central axis of the platform.

[0007] Furthermore, the moving component includes a connecting block and a lead screw, with the lead screw mounted in the middle of the connecting block.

[0008] Furthermore, the moving component also includes a movable cavity and a movable box, with the movable cavity located outside the lead screw and the movable box located outside the movable cavity.

[0009] Furthermore, a vacuum box is connected to the lower end of the platform, and a vacuum machine pipe is installed on the left side of the vacuum box.

[0010] Furthermore, the vacuum box has a suction cup pressure-holding cavity inside, and the vacuum box and the suction cup pressure-holding cavity are an integrated structure.

[0011] Furthermore, the adsorption block has an adsorption cavity in the middle, and a filter screen is installed on the top of the adsorption cavity.

[0012] Furthermore, a sealing valve is provided inside the adsorption chamber, and a spring is connected to the lower end of the sealing valve.

[0013] This utility model provides a vacuum adsorption worktable for a miniature CNC engraving machine, which has the following beneficial effects:

[0014] 1. This utility model uses a dust collection box that moves on the surface of the workbench and the adsorption block to clean the surface after carving by sucking up debris, so that it can be used later. The exhaust pipe and the dust collection box are connected to each other and connected to the air pipe and the dust collector to provide suction power. The cleaning brush moves with the dust collection box to clean the surface of the workbench and prevent impurities from sticking to the surface.

[0015] 2. In this utility model, the connecting block moves outside the screw as it rotates. When moving, the connecting block drives the dust collection box to move on the worktable surface to provide dust removal power. The moving box and the movable cavity are used for the installation of the screw and to provide space for the directional movement of the connecting block. The filter screen prevents impurities from entering the adsorption chamber during engraving. The sealing valve seals the adsorption chamber when there is no workpiece on the surface of the adsorption block to prevent vacuum. Attached Figure Description

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figure 1 As shown, a vacuum adsorption worktable for a miniature CNC engraving machine includes a table body 1 and a cleaning component 3. An adsorption block 2 is installed on the inner side of the table body 1. A moving component 4 for controlling the movement of a dust collection box 301 is provided on the side of the table body 1. Two sets of moving components 4 are symmetrically arranged about the central axis of the table body 1. The moving component 4 includes a connecting block 401 and a lead screw 402. The lead screw 402 is installed in the middle of the connecting block 401. The connecting block 401 moves outside the lead screw 402 as it rotates. When moving, the connecting block 401 drives the dust collection box 301 to move on the worktable surface to provide dust removal power. The moving component 4 also includes a movable cavity 403 and a moving box 404. The movable cavity 403 is provided outside the lead screw 402, and the moving box 404 is provided outside the movable cavity 403. The moving box 404 and the movable cavity 403 are used for the installation of the lead screw 402 and to provide space for the directional movement of the connecting block 401.

[0022] like Figure 2 As shown, the cleaning component 3 for cleaning the workbench surface is located at the upper end of the workbench body 1. The cleaning component 3 includes a dust collection box 301, a dust collection chamber 302, a cleaning brush 303, an exhaust pipe 304, and a connecting air pipe 305. The dust collection box 301 has a dust collection chamber 302 inside. The dust collection box 301 moves on the upper surface of the workbench body 1 and the adsorption block 2 to suck up debris from the carved workbench surface for subsequent use. The cleaning brush 303 is installed in the middle of the dust collection chamber 302. The cleaning brush 303 moves with the dust collection box 301 to clean the workbench surface and prevent impurities from sticking to the surface. The exhaust pipe 304 is installed at the upper end of the dust collection box 301. The exhaust pipe 304 communicates with the dust collection box 301. The left side of the exhaust pipe 304 is connected to the connecting air pipe 305, which is connected to a vacuum cleaner to provide suction power.

[0023] like Figure 3 As shown, a vacuum box 5 is connected to the lower end of the platform 1, and a vacuum machine pipe 6 is installed on the left side of the vacuum box 5. A suction cup pressure holding chamber 7 is opened inside the vacuum box 5, and the vacuum box 5 and the suction cup pressure holding chamber 7 are integrated structures. An adsorption chamber 8 is opened in the middle of the adsorption block 2, and a filter screen 9 is installed on the top of the adsorption chamber 8. The filter screen 9 prevents impurities from entering the adsorption chamber 8 during engraving. A sealing valve 10 is installed inside the adsorption chamber 8. The sealing valve 10 seals the adsorption chamber 8 when there is no workpiece on the surface of the adsorption block 2 to prevent vacuum. A spring 11 is connected to the lower end of the sealing valve 10.

[0024] In summary, the vacuum adsorption worktable of this miniature CNC engraving machine is first based on... Figures 1-3 The structure shown is used by placing the workpiece on the adsorption block 2 of the platform 1, then turning on the vacuum machine. This causes the vacuum machine connector 6 to create a vacuum inside the vacuum box 5 and the suction cup pressure chamber 7. For the adsorption chamber 8 without a workpiece covering it, a large amount of airflow passes through the adsorption chamber 8, causing the sealing valve 10 to settle and form a seal. For the adsorption chamber 8 covered by a workpiece, no airflow enters due to the workpiece covering it, and the sealing valve 10 does not move. The negative pressure is used to adsorb the workpiece through the gap between the sealing valve 10 and the adsorption chamber 8, achieving the effect of adsorbing the workpiece arbitrarily for subsequent processing. During processing, the filter screen 9 prevents impurities from entering the adsorption chamber during engraving. Inside 8, after processing, the motor at the end of the lead screw 402 is turned on, causing the connecting block 401 to move outside the lead screw 402 as it rotates. When moving, the connecting block 401 drives the dust collection box 301 to move on the workbench surface, providing power for dust removal. During cleaning, the dust collection box 301 moves on the upper surface of the table body 1 and the adsorption block 2. The exhaust pipe 304 is connected to the inside of the dust collection box 301, and the connecting air pipe 305 is connected to the vacuum cleaner to provide suction power. The cleaning brush 303 moves with the dust collection box 301 to clean the workbench surface, preventing impurities from sticking to the surface. This effectively removes debris from the engraved workbench surface, thus cleaning it for subsequent use.
