Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a double-head drilling machine. Background Technology

[0002] A drilling machine is a mechanical device specifically designed for drilling holes in workpieces. It uses a high-speed rotating drill bit to precisely create the desired holes on or inside the workpiece. Drilling machines are widely used in various manufacturing sectors, such as machining, mold making, and aerospace. They allow for adjustments to the drill bit's rotation speed and feed rate to meet different processing requirements, ensuring both drilling accuracy and efficiency.

[0003] Currently, the sliding door structure of drilling machine tools generally adopts a sliding overlapping design. For example, Chinese Patent No. CN103015841A discloses a CNC machine tool with linked double doors that can be operated with one hand, including an upper guide rail, a lower guide rail, an upper support roller, a lower support roller, an active door, a driven door, a transmission rack one, a transmission rack two, and a transmission gear. The upper and lower parts of the part where the machine tool door is located on one side of the machine tool are respectively provided with an upper guide rail and a lower guide rail. A transmission rack one is installed on the upper guide rail. An active door and a driven door are hung between the upper and lower guide rails. A transmission rack two is embedded in the top edge of the active door. Two sets of upper support rollers are installed on the outer edge of the top edge of the active door. Upper support rollers are installed in the upper support rollers. The upper support rollers are movably installed on the upper guide rail. A transmission gear is installed between transmission rack one and transmission rack two. The transmission gear is fixedly installed at one end of the driven door through a fixed shaft. This end always coincides with the active door.

[0004] Current sliding door structures for machine tools have some significant drawbacks: when the sliding door is opened, due to its overlapping design, a portion of the door always occupies space at the doorway, thus limiting the operating area. The only way to expand the operating space is to increase the overall width of the machine tool, which not only increases the machine's footprint but also significantly raises manufacturing costs, thus presenting a limitation.

[0020] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the embodiments of this utility model, and should not be construed as limiting the utility model.

[0021] Example 1: As Figure 1 , Figure 2 As shown, this embodiment discloses a dual-head drilling machine, including a drilling machine body. Sliding door assemblies 2 are provided on both sides of the drilling machine body. Each sliding door assembly 2 includes an upper guide rail assembly, a lower guide rail assembly, and a sliding door, all mounted on the drilling machine body. The upper guide rail assembly includes an upper horizontal guide rail 24 and an upper vertical guide rail 23. The lower guide rail assembly includes a lower horizontal guide rail 26 and a lower vertical guide rail 25. One end of the top of the sliding door is slidably connected to the upper horizontal guide rail 24, and the other end is slidably connected to the upper vertical guide rail 23. One end of the bottom of the sliding door is slidably connected to the lower horizontal guide rail 26, and the other end is slidably connected to the lower vertical guide rail 25. The top of the sliding door is slidably connected to the upper horizontal guide rail 24 and the upper vertical guide rail 23 via a slider 27, and the bottom is also slidably connected to the lower horizontal guide rail 26 and the lower vertical guide rail 25 via a slider 27. The sliding door and the slider 27 are rotatably connected.

[0022] The sliding door consists of a main door panel 21 and a side door panel 22 connected together, forming an angle between them. The design of the main door panel 21 and the side door panel 22 allows the main door panels 21 to close horizontally. The main door panel 21 is connected to the upper horizontal guide rail 24 and the lower horizontal guide rail 26, while the side door panel 22 is connected to the upper vertical guide rail 23 and the lower vertical guide rail 25. A handle 28 is provided on the slider 27 between the sliding door and the lower horizontal guide rail 26.

[0023] When it is necessary to close the sliding doors on both sides, simply manually pull the handle 28 of the bottom slider 27 of the main door panel 21 on both sides to move it towards the center. At this time, the side door panel 22 slides on the upper longitudinal guide rail 23 and the lower longitudinal guide rail 25, and the main door panel 21 slides on the upper transverse guide rail 24 and the lower transverse guide rail 26, thereby closing the sliding doors on both sides. If it is necessary to open the sliding doors, simply operate the handle 28 again to move the sliding plate in the opposite direction. When the sliding doors are opened, under the combined action of the upper longitudinal guide rail 23 and the lower longitudinal guide rail 25, the sliding doors can be retracted to both sides of the drilling machine body.

[0024] Compared to traditional folding sliding doors, this significantly saves operating space at the machine tool entrance, thereby reducing the overall design space of the machine tool and lowering production costs.

[0025] like Figure 1 The drilling machine body shown includes a machine base 1, a processing table 3 set inside the machine base 1, a drill bit assembly 4 set on the processing table 3, and a clamping device, wherein the clamping device is located above the drill bit assembly 4.

[0026] The clamping device is used to clamp the workpiece. In this embodiment, the machine base 1 is equipped with two drill bit assemblies 4 and a clamping device, which are respectively distributed on both sides of the machine base 1, thereby enabling simultaneous processing of two workpieces and significantly improving processing efficiency. Specifically, the clamping device includes a mounting base 5 slidably disposed on the processing table 3, a lower positioning member 6 disposed at the bottom of the mounting base 5, and an upper positioning member 7 slidably disposed on the mounting base 5. The bottom of the upper positioning member 7 is equipped with a ejector pin, while the surface of the lower positioning member 6 is provided with positioning protrusions.

[0027] The sliding of the mounting base 5 can be driven by a lead screw or similar drive mechanism. Similarly, the sliding of the upper positioning member 7 on the mounting base 5 can also be achieved using a lead screw or similar drive mechanism. The workpiece is clamped and fixed by the sliding of the upper positioning member 7. The workpiece is precisely positioned between the positioning protrusion and the ejector pin, and fixed by the clamping action between the upper positioning member 7 and the lower positioning member 6.

[0028] When drilling is required on the workpiece, the drill bit on the drill assembly 4 is first driven to rotate, and then the mounting base 5 is driven to slide downward, causing the workpiece to move down. The drill bit passes through the lower positioning member 6 to perform drilling on the workpiece.

[0029] To effectively collect the waste generated during processing, a waste collection device is installed below the machine base 1, and the table surface 31 of the processing table 3 is inclined. This device mainly includes a conveying device 9 located at the bottom of the machine base 1 and a handcart 10 located at the discharge end of the conveying device 9. Waste from the drill bit processing falls directly onto the table surface 31 of the processing table 3. Because the table surface 31 is inclined, the waste can slide from the table surface 31 to the conveying device 9. The conveying device 9 transports the waste via a conveyor belt (its specific structure and principle are common knowledge to those skilled in the art, and therefore will not be described in detail in this embodiment). The waste is transported to the handcart 10 for processing, which is more efficient and labor-saving compared to manual waste removal.

[0030] Example 2: Figures 3-5 As shown, due to the accumulation of waste on the worktable 31, even though the worktable 31 is designed to be inclined, some waste still adheres to it. Over time, this waste will gradually accumulate on the worktable 31, forming residues that are difficult to remove, eventually requiring manual cleaning. This not only consumes manpower but also reduces processing efficiency. Therefore, in this embodiment, a waste cleaning device 8 is provided on the worktable 31 of the processing table 3. The device includes a housing 81 installed on the processing table 3, an inlet port on the housing 81, an inner cavity inside the housing 81, and an outlet on one side of the housing 81 that communicates with the inner cavity. The inlet port can be detachably connected to a liquid inlet device or an air inlet device. The liquid inlet device can be a pump, and the air inlet device can be a ducted air conditioner or other equipment, which can selectively clean the waste through liquid or gas. Specifically, in this embodiment, an air inlet device is used. Air enters the inner cavity through the inlet port and is then sprayed out from the elongated outlet, covering the entire worktable 31, effectively cleaning the waste on the worktable 31 onto the conveying device 9.

[0031] To ensure the stability of the pressure distribution, this embodiment provides an upper inner cavity 84 and a lower inner cavity 85 spaced apart within the housing 81. The housing 81 is equipped with a first inlet port 82 communicating with the upper inner cavity 84 and a second inlet port 83 communicating with the lower inner cavity 85. Furthermore, one side of the housing 81 has a first outlet 86 communicating with the upper inner cavity 84 and a second outlet 87 communicating with the lower inner cavity 85. The first inlet port 82 and the second inlet port 83 are located on opposite sides of the housing 81, effectively improving the stability of the overall air pressure at the outlet of the housing 81. With the synchronized airflow from the first outlet 86 and the second outlet 87, the cleaning efficiency of debris on the tabletop 31 is significantly improved.

[0032] like Figure 6 - Figure 8As shown, due to the large width of the first outlet 86 and the second outlet 87, and the fact that the inlet pipe interface is usually located at one end of the outlet, the air pressure at the outlet position far from the inlet pipe interface gradually weakens, thus affecting the cleaning effect of waste debris. Therefore, in this embodiment, a flow guiding and agglomerating device is provided at both the first outlet 86 and the second outlet 87. The flow guiding and agglomerating device includes a baffle 11 rotatably connected to the housing 81, and the baffle 11 is also connected to the housing 81 by a spring (not shown). One end of the spring is fixed to the housing 81, and the other end is connected to the inner side of the baffle 11, providing a reset elastic force so that the baffle 11 can close the first and second openings under the action of the elastic force. On the one hand, when the waste debris cleaning device 8 is not in use, it can prevent waste debris from entering; on the other hand, it ensures that the outlet air pressure reaches a certain uniformity before the baffle 11 can be pushed open, thereby further ensuring that the air pressure of the first and second openings is more uniform.

[0033] Furthermore, in this embodiment, a guide channel 111 and multiple discharge channels 112 communicating with the guide channel 111 are provided on the inner side of the baffle 11. The discharge channels 112 are spaced apart and inclined to facilitate the airflow from the guide channel 111 into the exhaust channel, minimizing air pressure loss. Under the action of the guide channel 111, the airflow can be evenly distributed to the entire opening, and under the action of the exhaust channel, a certain air-gathering effect can be achieved at the corresponding position, increasing the local air pressure and thus optimizing the waste cleaning effect.

[0034] Since the first inlet port 82 and the second inlet port 83 are located in opposite positions, in this embodiment, the inclination directions of the multiple discharge slots 112 on the baffles 11 at the first outlet 86 and the second outlet 87 are also correspondingly opposite. Because the exhaust slots are spaced apart, the air pressure at the spaced-apart locations is relatively weak under the effect of increased air pressure. Therefore, in this embodiment, the positions of the discharge slots 112 on the baffles 11 at the first outlet 86 and the second outlet 87 are offset from each other, and the projections of the discharge outlet ranges of the discharge slots 112 overlap on both sides. Because the exhaust slots at the first outlet 86 and the second outlet 87 are offset from each other, a complementary effect of the air blowing positions at the first outlet 86 and the second outlet 87 is achieved while ensuring a large air pressure concentration in the exhaust slots, effectively avoiding areas with weak air pressure. Furthermore, in this embodiment, the housing 81 and the platform 31 are rotatably connected and rotated by a motor, allowing adjustment of the blowing angles of the first outlet 86 and the second outlet 87 to meet different needs.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
