Description

Technical Field

[0001] The present application relates to the field of drilling equipment, and in particular to a drilling machine for gear processing. Background Art

[0002] At present, gears have at least a center hole and a keyway hole. The center hole is used to insert the shaft, and the keyway hole is used to accommodate the keyway and work with the shaft. On some gears with larger diameters or heavier weights, it is often necessary to open some weight-reducing holes on the edge of the center hole to reduce the weight of the gear. The weight-reducing holes on the gears need to be drilled using a bench drill.

[0003] In the related art, since the drill bit of the bench drill will discharge the drilling waste chips outward when drilling, some of the waste chips will adhere to the drill bit. After the drill bit completes the drilling, a steel brush is needed to contact the drill bit, and then the drill bit is kept rotating to separate the waste chips from the drill bit.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects: The steel brush cannot contact every position of the drill bit, for example, it cannot completely contact the chip groove on the drill bit. In addition, after the steel brush has been used for a period of time, waste chips will also adhere to it. It is difficult to completely clean the waste chips on the drill bit when the steel brush with the waste chips adhered to it is subsequently used to clean the drill bit. Therefore, it is easy to cause poor cleaning of the waste chips on the drill bit. Summary of the invention

[0005] In order to improve the problem of poor cleaning of waste chips on the drill bit, the present application provides a drilling machine for gear processing.

[0006] The present application provides a gear processing drilling machine that adopts the following technical solution: A drilling machine for gear processing comprises: a drilling member connected to a lifting drive member to move the drilling member up and down; a cleaning member forming a through groove for inserting the drilling member, and a plurality of tough steel brushes are arranged on the inner wall surface of the through groove; a liquid injection member movably connected to the cleaning member so that the liquid injection member can block the lower end of the through groove or open the lower end of the through groove; a liquid injection groove for externally connected coolant is formed on the liquid injection member so that when the liquid injection member blocks the lower end of the through groove, the coolant is injected into the through groove; wherein, when the end of the drilling member moves up or down to the through groove, the liquid injection member blocks the lower end of the through groove, and the tough steel brush abuts against the drilling member.

[0007] By adopting the above technical scheme, the through groove is used for inserting the drilling part. Then, when the drilling part moves downward, the injection part seals the lower end of the through groove and injects coolant into the through groove. The drilling part is immersed in the coolant, and then the coolant contacts the drilling part more evenly, which is beneficial for the surface of the drilling part to move downward with the coolant. Then the injection part opens the lower end of the through groove, and all the coolant in the through groove falls onto the gear with the drill hole. The drilling part moves downward through the through groove and contacts the gear to be drilled to drill a hole, thereby ensuring that there is enough coolant before the drilling part drills a hole, which is beneficial to improving the quality of the drilling.

[0008] When the drilling part finishes drilling, the drilling part moves upward and reaches the through groove first. As the drilling part moves upward, the waste chips generated by drilling are taken out. The waste chips are easy to form a long curved body. The waste chips can be blocked and separated from the drilling part by the way that the drilling hole enters the through groove. After the drilling part enters the through groove, the cleaning part blocks the lower end of the through groove, and then the coolant is injected into the through groove. The drilling part is immersed in the coolant to cool the drilling part, which is beneficial to the quality of the next drilling. Small waste chips will adhere to the drilling part, and the drilling part is immersed in the coolant, and the coolant will overflow outward at the upper end of the through groove, so that the coolant is in a flowing state, which is beneficial to separate the waste chips on the drilling part from the drilling part. In addition, the drilling part rotates slowly in the through groove, which will produce relative motion with the coolant, and the inertia is more conducive to separating the waste chips on the drilling part from the drilling part. During the rising process of the drilling part, it will also come into contact with the tough steel brush. The tough steel brush will clean the waste chips adhered to the drilling part, and cooperate with the coolant to overflow outward, which can better separate the waste chips from the drilling part and discharge the waste chips out of the groove along with the coolant, thereby improving the cleaning and cooling effect of the drilling part. At the same time, it can also prevent the coolant from being sprayed strongly on the drilling part and causing splashing.

[0009] Optionally, the upper port of the cleaning piece is provided for the coolant to overflow outward; a receiving piece is arranged outside the cleaning piece to form a receiving chamber, and the cleaning piece is partially located in the receiving chamber; the receiving piece forms a hollow receiving surface so that waste chips on the drilling piece are carried on the receiving surface, and the coolant is discharged from the receiving chamber.

[0010] By adopting the above technical solution, the hollow receiving surface separates the waste chips from the coolant, so that the waste chips can be collected separately, thereby facilitating the collection and treatment of the waste chips.

[0011] Optionally, the edge of the cleaning piece forms a first conical guide surface; a second conical guide surface is formed on the receiving piece; the first conical guide surface and the second conical guide surface form a conical cavity, and the receiving surface is located above the conical cavity; the guide direction of the conical cavity intersects with the upward and downward movement trajectory of the drilling piece.

[0012] By adopting the above-mentioned technical solution, when the drilling part is located in the through groove, the coolant will be discharged outward in the tapered cavity, so that the cooling of the coolant after being discharged will also intersect with the upward and downward movement trajectory of the drilling part, so that the coolant can be poured on the gear after drilling or on the fixture for fixing the gear after the processed gear is taken away, thereby achieving the effect of cooling and cleaning the gear and the fixture for fixing the gear.

[0013] Optionally, a through hole is formed in the receiving member, and a limiting portion is formed on the cleaning member, and the through hole of the receiving member is inserted into the cleaning member until the receiving member abuts against the limiting portion.

[0014] By adopting the above technical solution, the receiving part can be disassembled from the cleaning part. Then, after a period of time, the receiving part is disassembled and the waste chips on the receiving part are cleaned up in a centralized manner.

[0015] Optionally, a connecting chamber and a plurality of rows of holes are formed in the cleaning member, the rows of holes are communicated with the through grooves, and the connecting chamber is communicated with the rows of holes; the connecting chamber is connected to an air source and / or the liquid injection tank.

[0016] By adopting the above technical solution and utilizing the arrangement of the discharge holes, the coolant can be discharged outward from the discharge holes at the same time, so that the coolant will have a greater impact on the tough steel brush, which is more conducive to the separation of waste chips from the tough steel brush, and at the same time, it will also have a greater impact on the drilling parts, which is also conducive to the separation of waste chips from the drilling parts. Connecting the external air source of the chamber can also allow air to be injected into the through groove, and the air will generate bubbles in the coolant, which is more conducive to the separation of waste chips from the tough steel brush and the drilling parts.

[0017] Optionally, the gear processing drilling machine also includes a power component, which is used to drive the cleaning component to move up and down and drive the injection component to seal or open the lower end of the through groove; when the drilling component moves down and is inserted into the through groove, the cleaning component moves down to be close to the gear to be drilled and the power component drives the injection component to open the lower end of the through groove; when the drilling component moves up to the through groove, the power component drives the injection component to seal the lower end of the through groove, and the cleaning component moves up to be away from the gear to be drilled.

[0018] By adopting the above technical solution, the power component drives the cleaning component to move up and down, so that the drilling component can be more located in the through groove, thereby increasing the process of heat dissipation of the drilling component by the coolant. In addition, when the cleaning component moves down to be close to the gear to be drilled, the waste chips discharged outward by the drilling component during drilling can be better blocked by the cleaning component or by the opened injection component, which has the effect of preventing the waste chips from splashing outward.

[0019] Optionally, a plurality of cut portions are formed at the lower end of the through groove, and the plurality of cut portions all extend downward to form an accommodating gap; an annular slot is formed on the injection piece, and when the injection piece seals the lower end of the through groove, the plurality of cut portions are all located in the annular slot.

[0020] By adopting the above technical solution, the setting of the cutting part can cut the longer curved waste chips. For example, when the drilling part is drilling, the drilling part discharges the waste chips outward. The waste chips may be in the shape of a longer curved piece, and the waste chips will rotate with the rotation of the drilling part. If they are not handled, they are likely to splash. Therefore, by using the setting of the cutting part, the waste chips can be cut off when they come into contact with the cutting part, thereby avoiding the formation of the longer waste chips. After the waste chips are cut off, the cut waste chips fall directly without splashing, preventing the waste chips from rubbing against the gears and the possible injuries to the staff due to the waste chips splashing. At the same time, it also prevents the waste chips from splashing, which ultimately makes it difficult to clean the waste chips, thereby better improving the safety of the drilling process and the convenience of later cleaning.

[0021] Optionally, the power component is used to drive the injection piece to rotate around a fixed axis so that the injection piece blocks or opens the lower end of the through groove; or the power component is used to drive the injection piece to translate laterally so that the injection piece blocks or opens the lower end of the through groove; the direction of the fixed axis matches the extension direction of the through groove; a plurality of cut portions are formed below the injection piece, and the plurality of cut portions all extend downward and form an accommodating gap.

[0022] By adopting the above-mentioned technical solution, since the power component drives the injection part to move, the cutting part cannot be installed at the lower end of the through groove. Therefore, installing the cutting part at the lower end of the injection part can cut off longer waste chips, thereby improving the safety of the drilling process and the convenience of subsequent cleaning.

[0023] By adopting the above technical solution, after the liquid injection part opens the lower end of the through slot, the liquid injection part is far away from the through slot, and therefore the liquid injection part is far away from the drilling part. A cutting part is set at a position far away from the drilling part to cut the longer waste chips far away from the drilling part. Therefore, after the waste chips are cut, even if they are not cut off, they are prone to bending. If the cutting part is too close to the drilling part, when the waste chips are not cut off, the bending of the waste chips will cause a large force on the cutting part, which is easy to accelerate the passivation of the cutting part and easily affect the normal discharge of the waste chips by the drilling part. Therefore, by setting the cutting part at a position far away from the through slot, the quality and efficiency of processing waste chips can be better guaranteed.

[0024] Optionally, an abutment portion having a flat surface is formed below the cutting portion, and when the cleaning member moves down to be close to the gear to be drilled, the flat surface of the abutment portion abuts against the end surface of the gear to be drilled.

[0025] By adopting the above technical solution, the abutment portion can prevent the cut portion from contacting the gear to be drilled when the cleaning piece moves downward, thereby protecting the gear to be drilled and the cut portion.

[0026] Optionally, a connecting portion is formed below the cutting portion, and the connecting portion is used to connect the plurality of abutting portions; a card slot is formed in the liquid injection piece, and the card slot is used to accommodate part of the cutting portion or all of the cutting portion.

[0027] By adopting the above technical solution, the card slot accommodates part or all of the cutting part, so when maintenance is needed, the cutting part can be pushed into the card slot to prevent the cutting part from leaking out to the outside and causing danger to maintenance personnel.

[0028] In summary, the present application includes at least one of the following beneficial technical effects: 1. Use the liquid injection part to seal the through groove and inject the coolant into the through groove, and then place the drilling part in the through groove, so that the coolant cools the drilling part. At the same time, a tough steel brush is arranged in the through groove to clean the drilling part, so that the drill bit is immersed in the coolant for cleaning, thereby improving the effect of cleaning waste chips; 2. The liquid injection part injects the coolant into the through groove, and the coolant will overflow outward at the upper end of the through groove, so that the coolant can be in a flowing state, and the waste chips in the through groove can be discharged outward in time. The flowing coolant and the steel brush and the drilling part generate a flow impact, which can better clean the drilling parts and improve the effect of cleaning the waste chips.

[0031] The following is combined with Figure 1-15 This application is described in further detail.

[0032] The embodiment of the present application discloses a drilling machine for gear processing. Example 1

[0033] A drilling machine for gear processing comprises: a drilling component 1, a lifting driving component 2, a cleaning component 3 and a liquid injection component 4.

[0034] The drilling member 1 is connected to the lifting drive member 2. The lifting drive member 2 drives the drilling member 1 to move up and down. The drilling member 1 moves down to drill the gear to be drilled. Among them, the lifting drive member 2 and the drilling member 1 are both installed on a drilling rig or form a bench drilling rig. A clamp for fixing the gear is set on the base of the bench drilling rig. The clamp adopts the existing technology and is not explained. The cleaning member 3 forms a through groove 31 for the drilling member 1 to be inserted. The inner wall surface of the through groove 31 is provided with a plurality of tough steel brushes 32. In this embodiment, the cleaning member 3 adopts a tube body. The through groove 31 is the inner cavity of the tube body. The tough steel brush 32 is a tough and soft steel brush. The steel brush can be inserted into the groove on the drilling member 1 to better clean the drilling member 1. The steel brushes are arranged in multiple layers from bottom to top, and there are gaps between each layer of steel brushes, so that there are gaps between the steel brushes, which is conducive to the separation of waste chips from the steel brushes.

[0035] The liquid injection member 4 is movably connected to the cleaning member 3, so that the liquid injection member 4 blocks the lower end of the through groove 31 or opens the lower end of the through groove 31. The liquid injection member 4 is formed with a liquid injection groove 41 for externally connecting the cooling liquid, so that when the liquid injection member 4 blocks the lower end of the through groove 31, the cooling liquid is injected into the through groove 31. The liquid injection member 4 is a plate body, and one end of the liquid injection groove 41 is opened at the side of the liquid injection member 4, and the other end is opened at the end of the liquid injection member 4. The liquid injection groove 41 is externally connected to the cooling liquid device through a hose, so that the cooling liquid is added to the through groove 31.

[0036] Among them, when the end of the drilling member 1 moves up or down to the through groove 31, the injection member 4 blocks the lower end of the through groove 31, and the tough steel brush 32 abuts against the drilling member 1. The through groove 31 is for the drilling member 1 to be inserted, so when the drilling member 1 moves down, the injection member 4 blocks the lower end of the through groove 31 and injects the coolant into the through groove 31, the drilling member 1 is immersed in contact with the coolant, and then the coolant contacts the drilling member 1 more evenly, which is conducive to the surface of the drilling member 1 moving down with the coolant, and then the injection member 4 opens the lower end of the through groove 31, and all the coolant in the through groove 31 falls on the gear with the drill hole, the drilling member 1 passes through the through groove 31 and moves downward, and contacts the gear to be drilled, and drills it, thereby ensuring that there is enough coolant before the drilling member 1 drills, which is conducive to improving the quality of drilling.

[0037] When the drilling component 1 finishes drilling, the drilling component 1 moves upward and will first reach the through groove 31. As the drilling component 1 moves upward, the waste chips generated by the drilling will be taken out, and the waste chips are likely to form a long curved body. The waste chips can be blocked and separated from the drilling component 1 by the way that the drilling enters the through groove 31. After the drilling component 1 enters the through groove 31, the cleaning component 3 blocks the lower end of the through groove 31, and then the coolant is injected into the through groove 31. The drilling component 1 is immersed in the coolant to cool the drilling component 1, which is beneficial to the quality of the next drilling. Small waste chips will adhere to the drilling component 1, and the drilling component 1 is immersed in the coolant, and the coolant will overflow outward at the upper end of the through groove 31, so that the coolant is in a flowing state, which is beneficial to separate the waste chips on the drilling component 1 from the drilling component 1. In addition, the drilling member 1 rotates slowly in the through groove 31, and will produce relative motion with the coolant, which is more conducive to separating the waste chips on the drilling member 1 from the drilling member 1 under the action of inertia. The drilling member 1 will also contact the tough steel brush 32 during the rising process, and the tough steel brush 32 cleans the waste chips adhering to the drilling member 1, and cooperates with the coolant to overflow outward, which can better separate the waste chips from the drilling member 1, and discharge the waste chips with the coolant out of the through groove 31, thereby improving the cleaning and cooling effect of the drilling member 1, and at the same time, it can also prevent the coolant from being strongly sprayed on the drilling member 1 and splashing.

[0038] Specifically, the upper port of the cleaning member 3 allows the coolant to overflow. A receiving member 5 is provided outside the cleaning member 3 to form a receiving chamber. The receiving member 5 adopts a cylindrical shell, and a part of the cleaning member 3 is located in the receiving chamber. The receiving member 5 forms a hollow receiving surface 511, so that the waste chips on the drilling member 1 are carried on the receiving surface 511, and the coolant is discharged from the receiving chamber. The hollow receiving surface 511 separates the waste chips from the coolant, so that the waste chips are collected separately, which is convenient for collecting and processing the waste chips. Among them, the bottom surface of the receiving member 5 is through, and an annular filter screen 51 is laid on the bottom surface of the receiving member 5, and the filter screen 51 forms a hollow receiving surface 511. Therefore, above the hollow receiving surface 511 is a storage chamber for storing waste chips. Example 2

[0039] The difference between Example 2 and Example 1 is that: the edge of the cleaning member 3 forms a first conical guide surface 33, and the first conical guide surface 33 is a conical surface that converges toward the through groove 31. The receiving member 5 forms a second conical guide surface 55, and the second conical guide surface 55 is a conical surface that converges toward the through groove 31. The first conical guide surface 33 and the second conical guide surface 55 form a conical cavity, and the receiving surface 511 is located above the conical cavity. The flow direction of the conical cavity intersects with the upward and downward movement trajectory of the drilling member 1.

[0040] Preferably, the receiving member 5 includes a first plate 52 and a second plate 53, the first plate 52 abuts against the first conical guide surface 33, and the second plate 53 forms a second conical guide surface 55, so that a conical chamber is formed between the first plate 52 and the second plate 53. Thus, a sleeve is formed in the middle of the receiving member 5, wherein, when the receiving member 5 is installed on the cleaning member 3, the receiving member 5 is inserted into the cleaning member 3 from bottom to top, a first magnet is arranged on the cleaning member 3, and a second magnet is arranged on the receiving member 5, and the first magnet and the second magnet are attracted. Thus, the receiving member 5 is fixed to the cleaning member 3. When the drilling member 1 is located in the through groove 31, the coolant will be discharged outward in the conical cavity, so that the cooling after the coolant is discharged will also intersect with the moving trajectory of the drilling member 1 moving up and down, so that the coolant can be poured on the gear after the drilling process or on the fixture of the fixed gear after the processed gear is taken away, which has the effect of cooling and cleaning the gear and the fixture of the fixed gear. Example 3

[0041] The difference between Example 3 and Example 1 is that a through hole is formed in the receiving member 5, and a limiting portion is formed on the cleaning member 3, and the limiting portion is a plate. The through hole of the receiving member 5 is inserted into the cleaning member 3 until the receiving member 5 abuts against the limiting portion. It is very convenient to install and remove the receiving member 5, and the receiving member 5 can be removed from the cleaning member 3. Then, after a period of time, the receiving member 5 is removed and the waste on the receiving member 5 is cleaned up in a centralized manner.

[0042] Specifically, a slide groove 54 is formed on the cleaning piece 3, and a Hua'an matching the slide rod is formed in the perforation. Therefore, when the receiving piece 5 is inserted into the cleaning piece 3, the slide rod is inserted into the slide groove 54 to prevent the receiving piece 5 from shaking relative to the cleaning piece 3, thereby reducing noise and avoiding damage to the cleaning piece 3 or the receiving piece 5 during the shaking process.

[0043] More specifically, an elastic cushion is sleeved on the outer wall of the slide rod, and the elastic cushion is used to better press against the slide groove 54 when the slide rod is located in the slide groove 54, thereby increasing the stability of the receiving member 5 and the cleaning member 3 after installation.

[0044] Specifically, since a filter screen 51 is formed below the receiving member 5 to discharge the coolant downward, the limiting portion preferably adopts a narrow plate body, and the narrow plate body only contacts a portion of the receiving member 5 to prevent the filter screen 51 from being blocked. Example 4

[0045] The difference between Example 4 and Example 1 is that a connecting chamber 34 and a plurality of rows of holes 35 are formed in the cleaning member 3 , the rows of holes 35 are communicated with the through groove 31 , and the connecting chamber 34 is communicated with the rows of holes 35 .

[0046] In one of the schemes, the connecting chamber 34 is connected to an external gas source and the injection groove 41. An outlet connected to the injection groove 41 is also formed on the injection part 4. When the injection part 4 blocks the cleaning part 3, the outlet is connected to the connecting chamber 34. The connecting chamber 34 adopts a plurality of circular holes, and the outlet is connected to some of the circular holes. An air injection hole is also provided on the cleaning part 3, and the other part of the circular holes is connected to the air injection hole. The air injection hole is connected to an external air pump through a hose, and the air pump injects the gas into the through groove 31 through the hose, the air injection hole, the connecting chamber 34 and the discharge port in sequence. Thereby, the coolant can be discharged outward at the discharge port, and the air can also be discharged at the discharge port. Among them, the opening direction of the discharge port is inclined upward or inclined downward, so that it can better impact on the tough steel brush 32 or the drilling part 1. By setting the discharge holes 35, the coolant can be discharged outward from the discharge holes 35 at the same time, so that the coolant will have a greater impact on the tough steel brush 32, which is more conducive to the separation of waste chips from the tough steel brush 32, and at the same time, it will also have a greater impact on the drilling member 1, which is also conducive to the separation of waste chips from the drilling member 1. The connection chamber 34 is connected to an external air source, and air can be injected into the through groove 31. The air will generate bubbles in the coolant, which is more conducive to the separation of waste chips from the tough steel brush and the drilling member 1.

[0047] In another solution, the connecting chamber 34 is connected to an external gas source. The connecting chamber 34 uses a plurality of circular holes, and a gas injection hole is also provided on the cleaning member 3. The connecting chamber 34 is connected to the gas injection hole, and the gas injection hole is connected to an external air pump through a hose. The air pump injects the gas into the through groove 31 through the hose, the gas injection hole, the connecting chamber 34 and the discharge port in sequence.

[0048] In another solution, the connecting chamber 34 is externally connected to the injection groove 41 , and the injection member 4 is also formed with an outlet communicating with the injection groove 41 . When the injection member 4 blocks the cleaning member 3 , the outlet communicates with the connecting chamber 34 .

[0049] In another embodiment, the connecting chamber 34 is externally connected to the cooling liquid, and a liquid injection tube capable of spraying the cooling liquid outward is inserted into the cleaning member 3 and communicated with the connecting chamber 34 . Example 5

[0050] The difference between Example 5 and Example 1 is that the gear processing drilling machine also includes a power component 6, which is used to drive the cleaning member 3 to move up and down and drive the injection member 4 to block or open the lower end of the through slot 31. The power component 6 includes: a crossbeam bracket 61, a lifting linear motor, a combination plate 63 and a first drive motor. The injection member 4 is rotatably connected to the cleaning member 3, and the axis of rotation of the injection member 4 and the cleaning member 3 is perpendicular to the axis of the through slot 31. The crossbeam bracket 61 is arranged on the base, the lifting linear motor is installed on the crossbeam bracket 61, and the combination plate 63 connects the output end of the lifting linear motor with the cleaning member 3, so that the lifting linear motor is used to drive the cleaning member 3 to move up and down. The first drive motor is installed on the combination plate 63. The first drive motor is used to drive the injection member 4 to rotate relative to the cleaning member 3, so as to block or open the lower end of the through slot 31. In some other schemes, the lifting linear motor is replaced by the first electric push rod 62.

[0051] When the drilling component 1 moves downward and is inserted into the through groove 31, the cleaning component 3 moves downward to be close to the gear to be drilled and the power component 6 drives the injection component 4 to open the lower end of the through groove 31; when the drilling component 1 moves upward to the through groove 31, the power component 6 drives the injection component 4 to block the lower end of the through groove 31, and the cleaning component 3 moves upward to be away from the gear to be drilled. The power component 6 drives the cleaning component 3 to move upward and downward, so that the drilling component 1 is more located in the through groove 31, thereby increasing the process of heat dissipation of the drilling component 1 by the coolant. In addition, when the cleaning component 3 moves downward to be close to the gear to be drilled, the waste chips discharged outward by the drilling component 1 can be better blocked by the cleaning component 3 or the opened injection component 4 during drilling, which has the effect of preventing the waste chips from splashing outward.

[0052] Specifically, a plurality of cutting portions 7 are formed at the lower end of the through groove 31, and the plurality of cutting portions 7 extend downward and form a receiving gap 71, and the receiving gap 71 is used for waste chips to enter. The cutting portion 7 is a cutter. An annular slot is formed on the injection part 4, and when the injection part 4 blocks the lower end of the through groove 31, the plurality of cutting portions 7 are located in the annular slot. The setting of the cutting portion 7 can cut longer curved waste chips. For example, when the drilling part 1 is drilling, the drilling part 1 discharges the waste chips outward. The waste chips may be in the shape of a long curved piece, and the waste chips will rotate with the rotation of the drilling part 1. If it is not handled, it is easy to cause splashing. Therefore, by using the setting of the cutting portion 7, the waste chips can be cut off when they come into contact with the cutting portion 7, thereby avoiding the formation of the longer waste chips. After the waste chips are cut off, they fall directly without splashing, which prevents the waste chips from scratching the gears and injuring the workers. It also prevents the waste chips from splashing, which ultimately makes it difficult to clean up the waste chips, thereby better improving the safety of the drilling process and the convenience of subsequent cleaning. Example 6

[0053] The difference between Example 6 and Example 5 is that: The power component 6 is used to drive the injection piece 4 to rotate around a fixed axis so that the injection piece 4 blocks or opens the lower end of the through slot 31. The direction of the fixed axis matches the extension direction of the through slot 31; a plurality of cutting portions 7 are formed below the injection piece 4, and the plurality of cutting portions 7 all extend downward and form a receiving gap 71. The power component 6 includes a second drive motor, which drives the injection piece 4 to rotate around the fixed axis. At this time, the injection piece 4 rotates close to the lower end of the cleaning piece 3. After the injection piece 4 opens the lower end of the through slot 31, the injection piece 4 is away from the through slot 31, and therefore the injection piece 4 is away from the drilling piece 1. The cutting portion 7 is set at a position away from the drilling piece 1 to cut the longer waste chips away from the drilling piece 1. Therefore, after the waste is cut, even if it is not cut off, it is easy to bend. If the cutting portion 7 is too close to the drilling member 1, when the waste is not cut off, the bending of the waste will cause a large force on the cutting portion 7, which is easy to accelerate the passivation of the cutting portion 7 and easily affect the normal discharge of the waste by the drilling member 1. Therefore, by arranging the cutting portion 7 at a position far away from the through groove 31, the quality and efficiency of processing the waste can be better guaranteed.

[0054] In another solution, the power component 6 is used to drive the injection part 4 to translate horizontally, so that the injection part 4 blocks or opens the lower end of the through groove 31. The power component 6 includes a second electric push rod 64. Another solution of the injection part 4 is that the injection part 4 is composed of two semicircular plates, and two second electric push plates are provided to drive the two semicircular plates to move closer to and away from each other. The injection groove 41 is formed in one of the semicircular plates, or in two semicircular plates.

[0055] Preferably, the injection groove 41 is formed in two semicircular plate bodies. For ease of description, the semicircular plate body is defined as the movable plate 42. The liquid inlet end of the injection groove 41 is on the arc side of the movable plate 42, and the liquid inlet end is externally connected to the coolant. The liquid outlet end of the injection groove 41 is at the center of the arc side of the movable plate 42. Therefore, when the two movable plates 42 are docked together, the coolant will be discharged upward into the through groove 31 at the center of the injection part 4. Then, when the two movable plates 42 are away from each other, the injection groove 41 will discharge the coolant outward in a parabolic manner, and the coolant will fall on the gear to be drilled. By controlling the speed of coolant injection, the coolant can fall on the drilling part 1, and then the coolant enters the hole being drilled along the drilling part 1, which can also have the effect of cooling the drilling part 1.

[0056] The liquid injection parts 4 are symmetrically located on both sides of the cleaning part 3, so the cutting parts 7 are also symmetrically located on both sides of the cleaning part 3, which has a better effect on cutting off waste chips.

[0057] In some other embodiments, a contact portion 72 having a flat surface is formed below the cutting portion 7. The contact portion 72 is a plate. When the cleaning member 3 moves down to be close to the gear to be drilled, the flat surface of the contact portion 72 contacts the end surface of the gear to be drilled. The arrangement of the contact portion 72 can prevent the cutting portion 7 from contacting the gear to be drilled when the cleaning member 3 moves down, thereby protecting the gear to be drilled and the cutting portion 7.

[0058] In some other embodiments, a connecting portion 73 is further formed below the cutting portion 7, and the connecting portion 73 is used to connect the plurality of the abutting portions 72. A slot 74 is formed in the liquid injection member 4, and the slot 74 is used to accommodate part of the cutting portion 7 or all of the cutting portion 7. The slot 74 accommodates part of the cutting portion 7 or all of the cutting portion 7, so that when maintenance is required, the cutting portion 7 can be pushed into the slot 74 to prevent the cutting portion 7 from leaking out to the outside and causing danger to the maintenance personnel. The connecting portion 73 facilitates pushing a plurality of cutting portions 7 into the slot 74 at the same time.

[0059] The implementation principle of a gear processing drilling machine in the embodiment of the present application is as follows: The drilling member 1 moves downward from the top position, and the drilling member 1 is inserted into the blocked through groove 31. The injection member 4 adds coolant into the through groove 31. The drilling member 1 continues to move downward, and the driving member drives the cleaning member 3 to move downward together, so that the cleaning member 3 and the injection member 4 move downward together with the drilling member 1. When the cleaning member 3 and the injection member 4 are close to the gear to be drilled, the driving member drives the injection member 4 to open the lower end of the through groove 31, and a large amount of coolant in the through groove 31 falls on the gear to be drilled. After the cleaning member 3 and the injection member 4 continue to move downward until the abutment portion 72 abuts against the gear to be drilled, the cleaning member 3 and the injection member 4 stop moving, and the drilling member 1 continues to move downward. After the drilling member 1 passes through the through groove 31, it drills the gear to be drilled.

[0060] After the drilling part 1 finishes drilling, the drilling part 1 moves up and into the through groove 31, and then the driving part drives the cleaning part 3 to move up, and the injection part 4 moves to block the lower end of the through groove 31. The drilling part 1 is located in the through groove 31, and the cleaning part 3 moves up with the drilling part 1, so that the drilling part 1 moves to the through groove 31, the drilling part 1 rotates in the through groove 31, the tough steel brush 32 contacts the drilling part 1, and the injection part 4 continuously adds coolant into the through groove 31, and makes the coolant overflow outward at the upper end of the through groove 31, thereby improving the effect of cleaning the waste chips on the drilling part 1.

[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
