Description

Technical Field

[0001] The utility model relates to the technical field of machining equipment, in particular to a bench drill which is convenient for cleaning debris. Background Art

[0002] A bench drill is a small drilling device equipped with a vise for operation. It is mostly manually drilled and is mostly used to process small holes below 15 mm. When the bench drill is working, the drill bit drills into the workpiece to complete the drilling work. A certain amount of debris will be generated in the process of the drill bit contacting the workpiece of different materials and completing the drilling. For example, when processing wooden materials, wood chips will be generated. At this time, a brush is needed to remove the wood chips so that the processing status can be observed. When processing metal materials, iron chips and spiral metal wires will be generated. The iron chips are retained in the drilling hole and need to be cleaned with a brush. After the spiral metal wire is separated from the workpiece, it will be thrown to another place due to centrifugal force and will not remain in the drilling hole. Or spray coolant. While the coolant cools the drill bit, the outflowing liquid can also take away some of the debris. In the current processing process, the use of a brush is still the main implementation method. First, it is convenient, and second, the cleaning position can be controlled. However, when the brush contacts the rotating drill bit, the rotating drill bit will roll the brush away, and the dragging force will cause the human hand to move toward the drill bit, which is dangerous. In addition, manual cleaning with a brush can only clean one side, and the back side is not easy to clean due to the drill bit. In addition, the manual cleaning method is not timely. Therefore, a cleaning method that can be efficient and fast is needed to replace manual cleaning to achieve safe and efficient work goals. Utility Model Content

[0045] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. As long as the effect of the utility model can be exerted, various changes can be made to the implementation scheme.

[0046] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0047] Reference Figure 1-5 A bench drill for facilitating the cleaning of debris according to the present embodiment is described.

[0048] In this embodiment, the bench drill comprises a bench drill body 1, a lifting sleeve 24 is adjustably connected to the column of the bench drill body 1, and a cleaning mechanism 2 is arranged on the front side of the lifting sleeve 24. The cleaning mechanism is used to clean the debris generated during the drilling process.

[0049] The cleaning mechanism 2 of this embodiment includes a first cleaning component 21, a second cleaning component 22 and a connecting component 23. The first cleaning component 21 has a first jet component, which performs a first-direction gas jet toward the working end of the bench drill body 1; the second cleaning component 22 has a second jet component, which performs a second-direction gas jet toward the working end of the bench drill body 1; the gas ejected by the first jet component and the second jet component blows away the debris generated during the drill bit processing. Gas blowing can avoid direct contact between other physical cleaning methods and the rotating drill bit, and can remove smaller impurities, which is safe and efficient.

[0050] The connecting component 23 is connected between the first cleaning component 21 and the second cleaning component 22, so that the second cleaning component 22 can adjust the angle on the first cleaning component 21 to spray gas in the second direction. When in use, the first cleaning component 21 is fixed to blow gas in the first direction, and one end of the second cleaning component 22 is rotatably connected to one end of the first cleaning component 21 through the connecting component 23, and when rotating and adjusting different positions, blowing and spraying at different positions are realized.

[0051] The first cleaning component 21 includes a first boss 214 having a first cavity, and the second cleaning component 22 includes a second boss 225 having a second cavity. The second boss 225 is rotatably connected to the first boss 214 through the connecting component 23, and the first jetting component is connected to the second jetting component through the connecting component 23. The second boss 225 is rotated and connected to the first boss 214 through the connecting component 2, so that when the second boss 225 rotates on the first boss 214, the first cavity and the second cavity can be connected, so that the gas in the first jetting component is transmitted to the second jetting component.

[0052] The connecting assembly 23 needs to realize the rotation of the second boss 225 and the communication between the first cavity and the second cavity. In this embodiment, the connecting assembly 23 includes a central hollow shaft 235 , a connecting ring, a rotating member 234 and a positioning ring 236 .

[0053] Specifically, the central hollow shaft 235 is connected to the first boss 214 and the second boss 225, and the two ends of the central hollow shaft 235 are respectively inserted into the first boss 214 and the second boss 225, so that the first cavity and the second cavity are connected. The connecting ring includes an upper stop ring 233 and a lower stop ring 237; the upper stop ring 233 is threadedly connected between the central hollow shaft 235 and the second boss 225, and the lower stop ring 237 is threadedly connected between the central hollow shaft 235 and the first boss 214; the upper stop ring 233 and the lower stop ring 237 are threadedly connected to the central hollow shaft 235, and abut against the second boss 225 and the first boss 214, so that the central hollow shaft 235 is limited on the second boss 225 and the first boss 214. Sealing gaskets are arranged on the inner sides of the upper stop ring 233 and the lower stop ring 237 to play a sealing role. The rotating member 234 is sleeved on the central hollow shaft 235, so that the central hollow shaft 235 rotates on the second boss 225 or the first boss 214. The positioning ring 236 covers the rotating member 234 and is fixedly connected to the second boss 225 or the first boss 214. When the second boss 225 rotates on the first boss 214 through the rotating member 234, the sealing gasket also plays a friction positioning function. Specifically, when the central hollow shaft 235 rotates, it drives the upper stop ring 233 and the lower stop ring 237 to rotate synchronously, and stops after rotating to a certain angle. At this time, the friction of the sealing gasket fixes the position of the second cleaning component 22 and does not continue to rotate and deviate.

[0054] A stopper 213 is provided on the top of the first housing 212 to limit the rotation angle of the first cleaning component 21. There are two stoppers 213, which are provided at both ends of the top of the first housing 212. When the second cleaning component 22 rotates, it abuts against the stopper 213, so that the second cleaning component 22 can be folded above the first cleaning component 21, preventing the second cleaning component 22 from affecting the normal operation of the bench drill when it is not working.

[0055] The connecting assembly 23 also includes a first cover group and a second cover group. The first cover group is fixed on the second boss 225 and is arranged corresponding to the central hollow shaft 235.

After the first cover group and the second cover group are disassembled, the components related to the central hollow shaft 235 can be installed and repaired.

[0056] Specifically, the first cover group includes an upper cover 231 fixed on the second boss 225, and a first sealing ring 232 is arranged between the upper cover 231 and the second boss 225; the second cover group includes a lower cover 239 fixed on the first boss 214, and a second sealing ring 238 is arranged between the lower cover 239 and the first boss 214.

[0057] The first cleaning assembly 21 also includes a first shell 212 and a first buckle plate 216. The first buckle plate 216 and the first shell 212 are buckled together to form a first cavity that can accommodate the first jet assembly. The jet end of the first jet assembly passes through the first shell 212. A first partition plate 218 is fixed at one end of the first cavity. The first partition plate 218 is arranged close to the first boss 214, and a first cavity is formed between the first partition plate 218 and the first shell 212. The first jet assembly is connected to the first cavity, so that the gas in the first jet assembly is transported to the first cavity, and then transported to the second cavity through the central hollow shaft 235.

[0058] In this embodiment, the first jet assembly includes a first gas chamber 217, which is a soft plastic tube or an air bag. The first gas chamber 217 is provided with an air inlet 211, a first nozzle 215 is provided at the front side of the first gas chamber 217, and a first pipe opening is provided at one end of the first gas chamber 217, and the first pipe opening penetrates the first partition 218 to connect the first gas chamber 217 with the first cavity. The external device fills the first gas chamber 217 with high-pressure gas through the air inlet 211, and the gas in the first gas chamber 217 is ejected through the first nozzle 215, and is also transported to the first cavity through the first nozzle, so as to transport gas to the central hollow shaft 235.

[0059] The second cleaning assembly 22 also includes a second shell 221 and a second buckle plate 224. The second buckle plate 224 and the second shell 221 are buckled together to form a second cavity that can accommodate the second jet assembly, and the jet end of the second jet assembly passes through the second shell 221; a second partition plate 227 is fixed at one end of the second cavity, and the second partition plate 227 is arranged close to the second boss 225, and a second cavity is formed between the second partition plate 227 and the second shell 221; wherein, the second jet assembly is connected to the second cavity, so that the gas transported to the second cavity by the central hollow shaft 235 enters the second jet assembly.

[0060] The second jet assembly includes a second gas chamber 222, a second nozzle 223 is disposed at the front side of the second gas chamber 222, and a second pipe opening is disposed at one end of the second gas chamber 222, and the second pipe opening penetrates the second partition plate 227 so that the second gas chamber 222 communicates with the second cavity. A valve 226 is disposed on the second pipe opening. After the valve 226 is opened, the gas in the second cavity enters the second gas chamber 222 through the second pipe opening, and then blows out high-pressure gas to the working end of the bench drill body 1 through the second nozzle 223, so as to blow away the debris generated during the drilling process in the second direction.

[0061] Working principle: high-pressure gas is filled into the first gas chamber 217 at the air inlet 211, and the high-pressure gas in the first gas chamber 217 is blown out toward the working end of the bench drill body 1 through the first nozzle 215, blowing away the debris generated during the drilling process in the first direction.
