Description

Technical Field

[0001] This invention relates to the field of automatic cleaning and chip removal technology for drilling machines, specifically to a drilling machine capable of automatic cleaning and chip removal. Background Technology

[0002] A drilling machine is a machine tool that primarily uses a drill bit to machine holes in a workpiece. Typically, the rotation of the drill bit is the main motion, and the axial movement of the drill bit is the feed motion. Drilling machines have a simple structure and relatively low machining accuracy. They can drill through holes and blind holes. By changing special tools, they can also perform reaming, counterboring, boring, or tapping. During machining, the workpiece remains stationary while the tool moves, aligning its center with the hole center and rotating (the main motion). The key characteristic of a drilling machine is that the workpiece is stationary while the tool rotates and feeds along the spindle. Operation can be manual or motorized.

[0003] During drilling or tapping operations, drilling machines generate a lot of chips. These chips need to be manually cleaned and removed by operators, which increases the labor intensity of the operators. Moreover, operators can only continue drilling or tapping operations after the cleaning is completed, which can easily delay the work process and lead to low efficiency. In addition, the chip collection process is time-consuming and difficult to clean up quickly. Furthermore, the water mist sprayed for cooling during drilling or tapping operations can easily escape and wet the working environment, making it difficult to collect and limit, thus causing certain inconveniences. Based on this, a drilling machine capable of automatic cleaning and chip removal is proposed. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the equipment is in use, the workpiece is clamped on the outside, and the mounting frame is moved by the screw drive mechanism one and the screw drive mechanism two, thereby adjusting the drilling position of the drilling motor and the drill bit. The winding roller and the automatic winding mechanism keep the rubber cover plate and the placement table in a flat and stretched state, thereby sealing the top of the upper box. When drilling or tapping, the air pump draws air, and the negative pressure of the airflow guides the airflow through the connecting pipe. The airflow and air pressure form a shape inside the upper box through the guidance of the connecting pipe. The negative pressure zone is formed because the rubber cover seals the top of the upper chamber, adsorbing the drilling debris and atomized water flow, which is then guided into the interior of the upper chamber. Through the connecting pipe, the water flows into the lower chamber below the water surface, where water mist and debris are absorbed and deposited. The debris is collected inside the filter box, thus guiding the airflow and debris, and preventing water mist from escaping and wetting the working environment. The debris is concentrated and guided with the airflow, making it easy to collect and process, reducing the labor intensity of the operators, and indirectly increasing the work efficiency.

[0016] 2. This solution uses a rubber cover plate, which is laid on the top of the upper box by the winding action of the winding roller. This makes it easy to follow the movement of the placement platform so that the rubber cover plate always covers the top of the upper box. During drilling or tapping operations, the top of the upper box is covered and sealed, allowing the airflow inside the upper box to be stably introduced through the positioning through hole. This plays a role in stabilizing airflow and guiding debris, which helps the auxiliary structure maintain a relatively stable working effect.

[0017] 3. When cleaning, the equipment is stopped and the sealing valve is opened to drain the water inside the lower box. The limit plate is rotated to release the outer limit of the sealing plate, and the sealing plate is pulled out so that the debris can be collected and deposited inside the filter box, which is convenient for cleaning after the operation. The stable use effect, the overall cleaning and maintenance are convenient, the labor intensity of the operators is reduced, and the efficiency of cleaning and maintenance is increased.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-9This invention provides a technical solution: a drilling machine capable of automatic cleaning and chip removal, comprising an upper housing 1, four connecting columns 2 fixedly installed at the bottom of the upper housing 1, a lower housing 3 fixedly installed at the bottom of the four connecting columns 2, support members 8 fixedly installed on both sides of the upper housing 1, a lead screw drive mechanism 9 driven on opposite sides of the top of the support member 8, a lead screw drive mechanism 10 driven on the outer side of the lead screw drive mechanism 19, and a mounting frame 11 driven on the outer side of the lead screw drive mechanism 10. A drilling motor 12 is fixedly installed on the outside of the upper housing 11. Two mounting clamps 13 are sleeved on the outside of the drilling motor 12. A lead screw transmission mechanism 31 is installed inside the upper housing 1. A placement platform 22 is connected to the top of the lead screw transmission mechanism 31. Several T-shaped grooves 23 are opened inside both sides of the placement platform 22. Two sets of T-shaped sliders 39 are slidably installed on the inner side of the T-shaped grooves 23. A support base 40 is fixedly installed on the top of each set of T-shaped sliders 39. A support plate 24 is fixedly installed on the top of the support base 40. Several positioning components 42 are fixedly installed at the bottom of the support plate 24. Positioning bolts 43 are internally threaded onto one end of each positioning component 42. Several positioning through holes 38 are opened in the middle of the placement platform 22. Winding rollers 18 are rotatably mounted on the outer sides of both ends of the upper housing 1 via bearing brackets. One end of each winding roller 18 is driven by an automatic winding mechanism 20. A rubber cover plate 21 is wound around the outer side of the winding roller 18. Limiting rollers 19 are rotatably mounted on the top of both ends of the upper housing 1 via bearing brackets. The bottom of the inner cavity of the upper housing 1... The upper chamber 1 is fixedly installed with a flow guide ramp 33. Several connecting pipes 36 are connected to the bottom of the upper chamber 1. Two sliding support bars 35 are fixedly installed at the bottom of the inner cavity of the lower chamber 3. A filter screen box 34 is slidably installed on the top of the sliding support bar 35. A sealing plate 4 is fixedly installed on the outside of the filter screen box 34. A sealing ring 45 is fixedly installed on the outside of both the sealing plate 4 and the filter screen box 34. A Y-shaped pipe 27 is connected to the top of the lower chamber 3. An air extraction pipe 26 is connected to the other end of the Y-shaped pipe 27. An air extraction pump 25 is connected to the other end of the air extraction pipe 26.

[0030] The working principle of the above technical solution is as follows: During use, the workpiece to be drilled is placed on top of the support base 40. The sliding support plate 24 causes the T-shaped slider 39 to move closer to the T-shaped slide groove 23 under its limit, fitting the outer side of the workpiece. The bottom of the workpiece is then placed on top of the support base 40. The clamping bolt 41 is then rotated to clamp the outer side of the workpiece. The positioning bolt 43 is then inserted into the positioning member 42 and extends into the positioning through hole 38. After fixing the workpiece, the mounting bracket 11 is moved via the screw drive mechanism 19 and the screw drive mechanism 20, thereby adjusting the drilling position of the drilling motor 12 and the drill bit 14. Next, the water supply pipe 15 is connected to an external water source and sprayed through the universal joint pipe 16 and the atomizing nozzle 17 to cool the drilling location. At the same time, the threaded rod transmission mechanism 31 in the drilling hole adjusts the position of the placement platform 22. When the placement platform 22 moves, it will pull the rubber cover plate 21 to move. The rubber cover plate 21 is kept in sliding contact with the top of the upper box 1 under the support of the limiting roller 19, and the rubber cover plate 21 and the placement platform 22 are kept in a flat and stretched state by the winding roller 18 and the automatic winding mechanism 20, thereby sealing the top of the upper box 1. When drilling or tapping, the air pump 25 is started, and the airflow The lower chamber 3 is evacuated to a negative pressure state via the suction pipe 26 and the Y-shaped pipe 27. Before drilling, water is added to the upper chamber 1 and the lower chamber 3 through the positioning through-hole 38, with the water level exceeding the bottom of the connecting pipe 36. The negative pressure of the airflow guides the airflow through the connecting pipe 36. The airflow and pressure, guided by the connecting pipe 36, create a negative pressure zone inside the upper chamber 1. Since the top of the upper chamber 1 is sealed by the rubber cover plate 21, the airflow enters through the gap in the positioning through-hole 38, adsorbing the drilling debris and atomized water, and guiding them into the interior of the upper chamber 1. The debris and water mist are guided by the inclined guide slope 33. The water flows down into the interior of the connecting pipe 36, and then through the guide of the connecting pipe 36 into the water below the surface of the lower tank 3, where water mist and debris are absorbed and deposited. The bursting bubbles and splashing water are intercepted by the fine defoaming filter 37, allowing airflow to pass through and reducing the possibility of splashing water being introduced into the air pump 25 through the Y-shaped pipe 27. The debris is collected inside the filter box 34, thereby guiding the airflow and debris, and preventing water mist from escaping and wetting the working environment. The debris is guided by the airflow and concentrated for easy collection and treatment, reducing the labor intensity of the operators and indirectly increasing the work efficiency.

[0031] In another implementation scheme, such as Figures 1-4 As shown, four connecting columns 2 are symmetrically and evenly distributed in a rectangular shape on opposite sides of the upper box 1 and the lower box 3. Four mounting feet 7 are fixedly installed at the bottom of the lower box 3. The four mounting feet 7 are symmetrically and evenly distributed in a rectangular shape at the bottom of the lower box 3.

[0032] The connecting column 2 creates a gap between the upper housing 1 and the lower housing 3, providing space for the installation of the connecting pipe 36 and the Y-shaped pipe 27. The mounting foot 7 raises the height of the lower housing 3, providing space for the installation and flow guidance of the air pump 25. It also allows the mounting foot 7 to be used to install the device in a suitable position by bolts, indirectly increasing the effectiveness of the device.

[0033] In another implementation scheme, such as Figures 1-4 As shown, two mounting clamps 13 are symmetrically fixedly installed on the outside of the drilling motor 12. The output end of the drilling motor 12 is clamped and installed with a drill bit 14 through an automatic changing chuck. A universal joint tube 16 is fixedly sleeved on the outside of the mounting clamps 13. A water supply pipe 15 is connected to the top of the universal joint tube 16, and an atomizing nozzle 17 is connected to the bottom of the universal joint tube 16. The position of the output end of the atomizing nozzle 17 corresponds to the position on the outside of the drill bit 14. Drill bit placement racks 46 are fixedly installed on the inside of the support member 8.

[0034] Mounting clamp 13 secures the drilling motor 12 and universal joint tube 16 to the outside of mounting bracket 11. Universal joint tube 16 facilitates adjustment of the spray position of atomizing nozzle 17, allowing for convenient atomized spraying at the drilling or tapping position of drill bit 14. It also moves with mounting bracket 11, and consequently with drilling motor 12 and drill bit 14, maintaining the atomized spraying position of atomizing nozzle 17 and ensuring structural stability. Using a conventional drill bit mounting bracket for fixed installation facilitates the replacement of drill bit 14 with a drilling tool. The drill bit holder 46 is used for drilling or tapping to remove chips and cool down during drilling and tapping operations. It is used to hold different specifications of drill bits 14 for tapping and drilling, so that operators can place them according to their specifications and dimensions and then replace and use the auxiliary equipment. The drill bit holder 46 is set in two rows symmetrically arranged inside the support member 8. The installation position of the drill bit holder 46 does not exceed the position of the support plate 24, and multiple specifications of drill bits are placed on the same horizontal line as the drill bits 14, so as to facilitate the replacement of drill bits 14 by automatic chuck changing.

[0035] In another implementation scheme, such as Figures 1-7 As shown, two nuts 44 are fixedly sleeved inside the support plate 24. Each of the two nuts 44 is threaded with a clamping bolt 41. Clamping rubber heads are fixedly installed at opposite ends of the clamping bolts 41. Positioning parts 42 are linearly and evenly distributed at the bottom of the support plate 24. The specifications and dimensions of the positioning bolts 43 are adapted to the specifications and dimensions of the positioning through holes 38. The positioning through holes 38 are rectangular and linearly and evenly distributed inside the placement platform 22. The two ends of the positioning through holes 38 are connected through the top and bottom of the placement platform 22.

[0036] Rotating the threaded connection between the clamping bolt 41 and the nut 44 causes the clamping rubber head to clamp onto the outside of the workpiece for easy clamping. The T-shaped slider 39 slides inside the T-shaped groove 23 to adjust the relative position of the support plate 24 and the support seat 40, facilitating corner support and auxiliary clamping and limiting of the workpiece. After adjustment, the position of the support plate 24 is fixed by inserting the positioning bolt 43 into the positioning part 42 and the positioning through hole 38, thus facilitating subsequent clamping of workpieces of the same specification after adjustment. The positioning through hole 38 serves to guide airflow and provide a through hole for introducing debris, and provides an insertion hole for adjusting the position of the positioning bolt 43, which facilitates the fit of the structure and makes it convenient for clamping and drilling auxiliary operations on different workpieces, thereby increasing the usability of the structure.

[0037] In another implementation scheme, such as Figures 1-8 As shown, the end of the rubber cover plate 21 away from the take-up roller 18 is fixedly installed on the outside of the placement platform 22. The automatic take-up mechanism 20 includes a mounting shell 2001 and a coil spring 2002. The mounting shell 2001 is fixedly installed on the outside of the upper box 1. One end of the take-up roller 18 is rotatably installed on the inner wall of the mounting shell 2001 through a bearing seat. The middle part of the coil spring 2002 is fixedly connected to the outside of the take-up roller 18, and the outer end of the coil spring 2002 is fixedly connected to the inner wall of the mounting shell 2001. The limiting roller 19 is located on the top of the rubber cover plate 21. Several reinforcing ribs 2101 are fixedly installed inside the rubber cover plate 21. The reinforcing ribs 2101 are linearly and evenly distributed inside the rubber cover plate 21. The rubber cover plate 21 is laid across the top of the upper box 1. The specifications and dimensions of the rubber cover plate 21 and the placement platform 22 are adapted to the specifications and dimensions of the upper box 1.

[0038] The rubber cover plate 21 is wound around the outside of the take-up roller 18, and the take-up roller 18 is subjected to the winding force of the automatic take-up mechanism 20, which generates a taut stretching effect on the rubber cover plate 21. Under the rolling support of the limit roller 19, the end of the take-up roller 18 maintains a close fit with the upper housing 1, reducing gaps. The coil spring 2002 generates a winding force on the take-up roller 18, causing the take-up roller 18 to maintain its winding action. The automatic take-up mechanism 20, supported internally by the mounting housing 2001, ensures... When laid across the top of the upper housing 1, it can maintain stability and avoid collapse. Through the rubber cover plate 21, it is laid on the top of the upper housing 1 by the winding action of the winding roller 18. It is easy to follow the movement of the placement platform 22 so that the rubber cover plate 21 always covers the top of the upper housing 1. It will cover and seal the top of the upper housing 1 during drilling or tapping operations, so that the airflow inside the upper housing 1 can be stably introduced through the positioning through hole 38, which plays a role in stabilizing airflow and guiding debris, and helps the auxiliary structure maintain a relatively stable working effect.

[0039] In another implementation scheme, such as Figures 1-9 As shown, the filter box 34 moves through the lower housing 3 and extends to the outside of the lower housing 3. The sealing ring 45 is fixedly installed on the outside of the sealing plate 4 and the filter box 34 respectively. A slot adapted to the sealing plate 4 and the filter box 34 is opened on one side of the lower housing 3. A positioning post 6 is fixedly installed on the outside of the lower housing 3. A limiting plate 5 is rotatably installed on the outside of the positioning post 6. The outside of the limiting plate 5 abuts against the outside of the sealing plate 4.

[0040] When cleaning is performed, the equipment is stopped and the sealing valve 32 is opened to drain the water inside the lower housing 3. The limit plate 5 is rotated to release the outer limit of the sealing plate 4, and the sealing plate 4 is pulled out so that the debris can be collected and deposited inside the filter screen box 34, which is convenient for cleaning after the operation. The outer side of the sealing plate 4 and the filter screen box 34 is sealed at the groove by the sealing ring 45, which ensures stable use, convenient overall cleaning and maintenance, reduces the labor intensity of operators, and increases the efficiency of cleaning and maintenance.

[0041] In another implementation scheme, such as Figures 1-4 As shown, the bottom end of the connecting pipe 36 is connected to the inside of the lower box 3, and the top end of the connecting pipe 36 passes through the upper box 1 and connects to the top of the guide slope 33. The top end of the connecting pipe 36 is adapted to the slope of the guide slope 33, and the bottom end of the connecting pipe 36 is flush with the top of the filter box 34. The connecting pipe 36 is evenly distributed in a rectangular linear pattern on the opposite sides of the upper box 1 and the lower box 3. A fine defoaming filter 37 is fixedly sleeved on the outside of the connecting pipe 36.

[0042] The connecting pipe 36, through the inclined effect of the guide ramp 33, guides the water and debris flowing into the upper chamber 1 and introduces them into the lower chamber 3. The positioning through hole 38 allows both airflow and water flow. During operation, water is added to the upper chamber 1 and the lower chamber 3 through the positioning through hole 38. After the water is full, it is discharged through the overflow pipe 28 and the check valve 29. The water level is maintained at the bottom of the fine defoaming filter 37. The bottom end of the connecting pipe 36 guides the airflow, water mist and debris into the bottom of the fine defoaming filter 37 and the inside of the filter box 34. The top of the filter box 34 is flush with the top of the connecting pipe 36 to avoid obstruction during stretching. The fine defoaming filter 37 intercepts air bubbles and splashing water, allowing airflow to pass through and reducing water droplets in the airflow, thus indirectly increasing the effectiveness of use.

[0043] In another implementation scheme, such as Figures 1-4As shown, the side of the lower housing 3 away from the sealing plate 4 is connected to an overflow pipe 28, and a check valve 29 is installed inside the overflow pipe 28. The side of the lower housing 3 away from the sealing plate 4 is connected to a drain pipe 30, and a sealing valve 32 is movably installed inside the drain pipe 30. The overflow pipe 28 is connected to the top of the fine defoaming filter 37, and the drain pipe 30 is connected to the bottom of the filter box 34.

[0044] The function of overflow pipe 28 and check valve 29 is that, as the operation progresses, water mist will be intercepted by the airflow inside the lower chamber 3, and the drainage effect of debris will increase the water level inside the lower chamber 3. The height of the water level will affect the operation effect. Therefore, the overflowing water flow is discharged through the overflow pipe 28 and check valve 29 to stabilize the water level. In addition, the check valve 29 allows the fluid to flow in one direction while preventing it from flowing back. This ensures both the operation effect of the internal airflow and the overflow effect when the water flow is higher than the overflow pipe 28, which is convenient for coordinated operation. The function of drain pipe 30 and sealing valve 32 is to open and drain the water inside the lower chamber 3 to facilitate cleaning and maintenance.

[0045] In another implementation scheme, such as Figures 1-4 As shown, the air pump 25 is fixedly installed at the bottom of the lower housing 3, and the end of the Y-shaped tube 27 away from the air extraction tube 26 is symmetrically connected to the top of the inner cavity of the lower housing 3.

[0046] The air pump 25 ensures the suction effect of the airflow, and its installation position is not limited to the bottom of the lower box 3, which facilitates the demonstration of the effect. The Y-shaped structure of the Y-shaped tube 27 ensures the connection effect and ensures the suction operation.

[0047] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
