Description

Technical Field

[0001] This utility model relates to the field of drilling, and in particular to high-efficiency pneumatic drilling equipment. Background Technology

[0002] Drilling equipment typically consists of a driver, a drilling tool, a moving mechanism, and a fixing mechanism. The driver drives the drilling tool to rotate and perform the drilling operation. One method involves the moving mechanism driving the driver to move, while the fixing mechanism secures the workpiece to be drilled. Another method involves the moving mechanism driving the workpiece to move, while the fixing mechanism secures the driver.

[0003] However, because of the high stability of motor drive, drilling equipment generally uses motor drive. However, pneumatic drive is also used in some specific situations. Traditional pneumatic drilling machines, such as the technical solution protected by the patent application number CN201120004882.0, invention name pneumatic drilling machine, have low transmission efficiency and large energy loss. Utility Model Content

[0004] Therefore, it is necessary to provide a high-efficiency pneumatic drilling device to address the technical problems of low transmission efficiency and high energy loss in traditional pneumatic drilling machines.

[0005] A high-efficiency pneumatic drilling device includes: a receiving shell, two rotating mechanisms, and a drilling mechanism; The receiving housing includes a drive housing, a receiving base plate, a connecting plate, and a connecting handle. The drive housing has a cuboid structure and two rotating cavities are formed inside, which are connected. The side of the drive housing with the rotating cavities is connected to the receiving base plate by several screws. The side of the receiving base plate facing away from the drive housing is connected to the connecting plate by several screws. The connecting handle is connected to one end of the drive housing. The front end of the drive housing has an air inlet that is connected to an external air source. The rear end of the drive housing has an exhaust port. Both the air inlet and the exhaust port are connected to the connection between the two rotating cavities. A through hole is formed at the bottom of the drive housing. Each of the aforementioned rotating mechanisms is correspondingly disposed in a rotating cavity. Each rotating mechanism includes two rotating bearings, a rotating column, and a drive gear. One rotating bearing is embedded in the receiving base plate, and the other rotating bearing is embedded in the inner wall of the drive housing. The rotating column is adapted to the rotating bearing, with each end of the rotating column correspondingly inserted into and connected to the inner ring of one of the rotating bearings. The drive gear is adapted to the rotating column, sleeved on the rotating column, and connected to the rotating column. The two drive gears mesh, and the air intake direction of the air inlet faces the junction of the two drive gears. The drilling mechanism includes a connector, a receiving column, and a drilling tool; the connector passes through the through hole and is connected to a rotating column, the end of the connector away from the rotating column is connected to the receiving column, and the drilling tool is connected to the end of the receiving column away from the connector; the connector is adapted to the through hole, the connector is inserted into the through hole and is rotatably connected to the drive housing.

[0006] In one embodiment, the connector is a cylindrical structure.

[0007] In one embodiment, the connector is a circular tubular structure.

[0008] In one embodiment, the supporting column is a cylindrical structure.

[0022] Please refer to the following: Figures 1 to 6 This utility model provides a high-efficiency pneumatic drilling device 10, including: a receiving housing 100, two rotating mechanisms 200 and a drilling mechanism 300.

[0023] The receiving housing 100 includes a drive housing 110, a receiving base plate 120, a connecting plate 130, and a connecting handle 140. The drive housing 110 has a cuboid structure and two rotating cavities 101 are formed inside, which are connected. The side of the drive housing 110 with the rotating cavities 101 is connected to the receiving base plate 120 by a number of screws. In this embodiment, the receiving base plate 120 has a rectangular plate structure. In another embodiment, the receiving base plate 120 has a circular plate structure. The side of the receiving base plate 120 facing away from the drive housing 110 is connected to the connecting plate 130 by a number of screws. In this embodiment, the connecting plate 130 has a rectangular plate structure. In another embodiment, the connecting plate 130 has a circular plate structure. The connecting handle 140 is connected to one end of the drive housing 110. In this embodiment, the connecting handle 140 and the drive housing 110 are integrally formed. The drive housing 110 has an air inlet 102 at its front end, which is connected to an external air source. The drive housing 110 has an exhaust port 103 at its rear end. Both the air inlet 102 and the exhaust port 103 are connected to the junction of the two rotating chambers 101. The drive housing 110 has a through hole 104 at its lower part.

[0024] Each rotating mechanism 200 is correspondingly disposed in a rotating cavity 101. The rotating mechanism 200 includes two rotating bearings 210, a rotating column 220, and a drive gear 230. One rotating bearing 210 is embedded in the receiving base plate 120, and the other rotating bearing 210 is embedded in the inner wall of the drive housing 110. The rotating column 220 is adapted to the rotating bearing 210, with each end of the rotating column 220 correspondingly inserted into and connected to the inner ring of the rotating bearing 210. The drive gear 230 is adapted to the rotating column 220, and is sleeved on and connected to the rotating column 220. The two drive gears 230 mesh, and the air intake direction of the air inlet 102 faces the junction of the two drive gears 230.

[0025] The drilling mechanism 300 includes a connector 310, a receiving post 320, and a drilling tool 330. The connector 310 passes through a through hole 104 and connects to a rotating post 220.

[0026] During operation, the aforementioned high-efficiency pneumatic drilling equipment 10 receives high-pressure gas from the output end of an external air source through the air inlet 102, which then feeds it into the two rotating chambers 101. Because the air inlet 102 connects to the two rotating chambers 101, the high-pressure gas enters the drive housing 110 and drives the two drive gears 230 to rotate. This design allows for efficient utilization of the high-pressure gas's power. The drive gears 230 drive the rotating column 220 to rotate. One end of the rotating column 220 is rotatably connected to the drive housing 110 via a rotating bearing 210, and the other end is rotatably connected to the receiving base plate 120 via another rotating bearing 210.
