[0035] Please also refer to Figures 1 to 3 Now, a drilling machine vacuum suction cup device provided in an embodiment of the present application is described.

[0036] The vacuum suction cup device of a drilling machine comprises: a suction cup base 1, a sealing strip 10, a vacuum pumping interface 9, and a small vacuum pumping motor 2.

[0037] Specifically, the suction cup base 1 is provided with an edge groove; the sealing strip 10 is a ring-shaped sealing strip 10, and the sealing strip 10 is fixedly connected to the edge groove. A sealed cavity 15 is formed between the suction cup base 1, the sealing strip 10 and the target workpiece (the target workpiece can be a flat aluminum part, stainless steel plate, plastic, wood board, floor tile, marble, glass, etc.); the vacuum interface 9 is provided on the suction cup base 1 and is connected to the cavity 15; the small vacuum motor 2 is installed on the side of the suction cup base 1 away from the sealing strip 10, and the small vacuum motor 2 is connected to the vacuum interface 9, and the vacuum motor is used to vacuum the cavity 15 so that the suction cup base 1 can be fixed on the target workpiece.

[0038] Advantageous effects compared with the prior art: an edge groove is provided through the suction cup base 1; the sealing strip 10 is preferably an annular sealing strip 10, and the annular sealing strip can reduce the joint sealing problem, and the sealing strip 10 can be fixedly connected to the edge groove by means of glue, or fixedly connected to the edge groove by other means, and a sealed cavity 15 is formed between the suction cup base 1, the sealing strip 10 and the target workpiece; the vacuum interface 9 is provided on the suction cup base 1 and is connected to the cavity 15; the small vacuum motor 2 is installed on the side of the suction cup base 1 away from the sealing strip 10, and the small vacuum motor 2 is connected to the vacuum interface 9, and the vacuum motor is used to vacuum the cavity 15, so that the suction cup base 1 can be fixed on the target workpiece. The drilling machine 5 can not only perform drilling operations on metal iron plates, but also perform drilling operations on flat workpieces such as aluminum parts, stainless steel plates, plastics, wooden boards, floor tiles, marble, glass, etc., which greatly improves the application range of the drilling machine 5.

[0039] In order to further prevent dust particles from entering the vacuum motor 2 through the vacuum interface 9 when the vacuum motor 2 is working, a filter 13 is installed at the vacuum interface 9.

[0040] As a further preferred embodiment, the drilling machine vacuum suction cup device further includes a pressure relief button 12. Specifically, the pressure relief button 12 includes a pressing rod and a return spring. A pressure relief hole 14 is provided on the suction cup base 1. The pressing rod is slidably connected to the pressure relief hole 14. The return spring is sleeved on the pressing rod, with one end fixedly connected to the pressing rod and the other end abutting against the suction cup base 1. A sealing piston is installed at the connection between the pressing rod and the pressure relief hole 14.

[0041] The pressure relief button 12 has a pressure relief position and a sealing position. When the pressure relief button 12 is in the pressure relief position, the pressing rod moves downward, separating the sealing piston from the pressure relief hole 14 to form an air flow channel. The cavity 15 is connected to the air, making the atmospheric pressure in the cavity 15 the same as the external air pressure. The suction cup base 1 is released from the target workpiece, and the suction cup base 1 can be removed from the target workpiece.

[0042] When the pressure relief button 12 is in the sealing position, the pressing rod, under the action of the return spring, causes the sealing piston to block the pressure relief hole 14, and the pressure relief button 12 closes the channel connecting the cavity 15 with the outside air. Under the action of the vacuum motor 2, the suction cup base 1 is fixed on the target workpiece.

[0043] As a further preferred embodiment, the drilling machine vacuum suction cup device further includes: a vacuum pressure switch 3 and a pressure indicator light 6.

[0044] Specifically, the vacuum pressure switch 3 is installed on the suction cup base 1. The vacuum pressure switch 3 is a prior art and will not be described in detail here. The vacuum pressure switch 3 is connected to the cavity 15 and has an on position and an off position; the pressure indicator light 6 is installed on the drilling machine fixing mechanism 4, and the drilling machine fixing mechanism 4 is fixedly connected to the suction cup base 1. The pressure indicator light 6 is electrically connected to the vacuum pressure switch 3, and the drilling machine fixing mechanism 4 is connected to the drilling machine 5. The specific connection relationship is a prior art and will not be described in detail here. For details, please refer to the utility model patent with publication number CN221289622U.

[0045] When the vacuum degree in the cavity 15 reaches the preset value of the vacuum pressure switch 3, the vacuum pressure switch 3 is in the on position and the pressure indicator light 6 is on; when the vacuum degree in the cavity 15 is lower than the preset value of the vacuum pressure switch 3, the vacuum pressure switch 3 is in the off position and the pressure indicator light 6 is off.

[0046] The drilling machine fixing mechanism 4 is provided with a drilling machine switch 7, and the drilling machine switch 7 is electrically connected to the drilling machine 5; the drilling machine switch 7 is used to start the drilling machine 5 after the pressure indicator light 6 is on. The drilling machine fixing mechanism 4 is also provided with a vacuum small motor switch 8, and the vacuum small motor switch 8 is electrically connected to the vacuum small motor 2. A cover 11 is fixedly connected to the side of the suction cup base 1 away from the sealing strip 10, and the vacuum pressure switch 3 and the vacuum small motor 2 are both located in the cover 11. The end of the pressing rod away from the cavity 15 passes through the cover 11, and the pressing rod has a limiting portion, which abuts against the inner wall of the cover 11 under the action of the reset spring to prevent the pressing rod from being separated from the cover 11 under the action of the reset spring.

[0047] First, place the drilling machine vacuum suction cup device on a flat target workpiece, turn on the vacuum motor switch 8, the vacuum motor 2 starts working, and the cavity 15 at the bottom of the suction cup base 1 is vacuumed. When the vacuum degree in the cavity 15 reaches the preset value of the vacuum pressure switch 3, the circuit connected to the pressure indicator light 6 is connected, and the pressure indicator light 6 lights up to ensure that the device and the target workpiece are firmly fixed. Then you can turn on the drilling machine switch 7 and start the drilling machine 5 to start working. This plays a good role in safety protection. When drilling is completed and needs to be moved, just turn off the vacuum motor switch 8 and press the pressure relief button 12 to move the device.

[0048] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
