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] Currently, a gear has at least a center hole and a keyway hole. The center hole is used to insert a shaft, and the keyway hole is used to accommodate a keyway and is used in cooperation with the shaft. For some gears with relatively large diameters or relatively thick and heavy ones, it is often necessary to open some weight-reducing holes at the edge of the center hole to reduce the weight of the gear. A bench drill is required for drilling the weight-reducing holes on the gear.

[0003] In the related art, since the drill bit of the bench drill will discharge the drilling waste chips outwards during drilling, some waste chips will adhere to the drill bit. After the drill bit finishes drilling, it is necessary to use a steel brush to contact the drill bit, and then keep the drill bit rotating to separate the waste chips on the drill bit from the drill bit.

[0004] Regarding the above related art, the inventor believes that there are the following defects:

[0005] The steel brush cannot contact every position of the drill bit. For example, it cannot completely contact the chip flutes on the drill bit. Moreover, after the steel brush is used for a period of time, it will also adhere to waste chips. When using the steel brush with adhered waste chips to clean the drill bit later, it is difficult to completely clean the waste chips on the drill bit. Therefore, it is easy to cause a poor cleaning of the waste chips on the drill bit. Summary of the Invention

[0006] In order to improve the problem that it is easy to cause poor cleaning of the waste chips on the drill bit, the present application provides a drilling machine for gear processing.

[0007] The drilling machine for gear processing provided by the present application adopts the following technical solutions:

[0008] A drilling machine for gear processing includes: a drilling member connected to a lifting driving member to move the drilling member up and down; a cleaning member forming a through groove for the drilling member to insert, and a plurality of resilient steel brushes are provided on the inner wall surface of the through groove; a liquid injection member movably connected to the cleaning member to block or open the lower end of the through groove; a liquid injection groove for connecting an external 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 resilient steel brushes abut against the drilling member.

[0009] By adopting the above technical solution, the through groove is provided for the drilling part to be inserted. Then, when the drilling part moves downward, the liquid injection part seals the lower end of the through groove and injects the coolant into the through groove. The drilling part is in immersion contact with the coolant, and then the coolant contacts the drilling part more evenly, which is beneficial to the downward movement of the drilling part with the coolant wrapped on its surface. Then, the liquid injection part opens the lower end of the through groove, and all the coolant in the through groove falls onto the gear with holes to be drilled. The drilling part penetrates the through groove and moves downward to contact the gear to be drilled and drill holes in it, so as to ensure that there is enough coolant before the drilling part drills, which is beneficial to improving the drilling quality.

[0010] When the drilling of the drilling part is completed, the drilling part moves upward. The drilling part will first reach the through groove. Since the drilling part will carry out the waste chips generated by drilling outwards when moving upward, the waste chips are easy to form a relatively long curved body. The waste chips can be blocked and separated from the drilling part by using the way of entering the through groove. After the drilling part enters the through groove, the cleaning part seals 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. Fine waste chips will adhere to the drilling part. The drilling part is immersed in the coolant, and the coolant will overflow outwards at the upper end of the through groove, so that the coolant is in a flowing state, which is beneficial to separating the waste chips on the drilling part from the drilling part. In addition, when the drilling part rotates slowly in the through groove, it will have a relative movement with the coolant, and the inertial effect is more beneficial to separating the waste chips on the drilling part from the drilling part. During the upward movement of the drilling part, it will also contact with the ductile steel brush. The ductile steel brush cleans the waste chips adhering to the drilling part and cooperates with the outward overflow of the coolant, which can better separate the waste chips from the drilling part and discharge the waste chips out of the through groove with the coolant, improving the cleaning and cooling effect on the drilling part. At the same time, it can also prevent the coolant from splashing strongly on the drilling part.

[0011] Optionally, the upper port of the cleaning part is for the coolant to overflow outwards; a receiving part forming a receiving chamber is arranged outside the cleaning part, and part of the cleaning part is located in the receiving chamber; the receiving part forms a hollow receiving surface so that the waste chips on the drilling part are carried on the receiving surface and the coolant is discharged from the receiving chamber.

[0012] By adopting the above technical solution, the hollow receiving surface separates the waste chips from the coolant, so as to collect the waste chips separately, which is convenient for collecting and processing the waste chips.

[0013] Optionally, the edge of the cleaning part forms a first conical guiding surface; a second conical guiding surface is formed on the receiving part; the first conical guiding surface and the second conical guiding surface form a conical channel, and the receiving surface is located above the conical channel; the guiding direction of the conical channel intersects with the moving tracks of the upward and downward movement of the drilling part.

[0014] By adopting the above technical solution, when the drilled part is located in the through groove, the coolant will be discharged outward from the conical channel. Therefore, after the coolant is discharged, the cooling will also intersect with the upward and downward movement trajectories of the drilled part, enabling the coolant to be sprayed on the gear after drilling or on the fixture for fixing the gear after removing the processed gear, achieving the effects of cooling and cleaning the gear and the fixture for fixing the gear.

[0015] Optionally, a through hole is formed in the receiving part, a limiting part is formed on the cleaning part, and the through hole of the receiving part is sleeved on the cleaning part until the receiving part abuts against the limiting part.

[0016] 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 centrally cleaned.

[0017] Optionally, a connecting chamber and a plurality of drain holes are formed in the cleaning part. The drain holes communicate with the through groove, and the connecting chamber communicates with the drain holes; the connecting chamber is externally connected to a gas source and / or the liquid injection groove.

[0018] By adopting the above technical solution, by means of the arrangement of the drain holes, the coolant can also be discharged outward from the drain holes, so that the coolant will generate a greater impact force on the ductile steel brush, which is more conducive to the waste chips detaching from the ductile steel brush. At the same time, it will also generate a greater impact on the drilled part, which is also conducive to the waste chips detaching from the drilled part. Connecting the connecting chamber to the external gas source can also inject air into the through groove, and the air will generate bubbles in the coolant, which is more conducive to the detachment of the waste chips from the ductile steel brush and the drilled part.

[0019] Optionally, the drilling machine for gear processing further includes a power component, which is used to drive the cleaning part to move up and down and drive the liquid injection part to block or open the lower end of the through groove; when the drilled part moves down and inserts into the through groove, the cleaning part moves down to be close to the gear to be drilled and the power component drives the liquid injection part to open the lower end of the through groove; when the drilled part moves up into the through groove, the power component drives the liquid injection part to block the lower end of the through groove, and the cleaning part moves up to be away from the gear to be drilled.

[0020] By adopting the above technical solution, the power component drives the cleaning part to move up and down, which can make the drilled part more located in the through groove, thereby increasing the process of the drilled part being cooled by the coolant. In addition, when the cleaning part moves down to be close to the gear to be drilled, during drilling, the waste chips discharged outward by the drilled part can be better blocked by the cleaning part or the opened liquid injection part, having the effect of preventing the waste chips from splashing outward randomly.

[0021] Optionally, a plurality of cutting portions are formed at the lower end of the through groove, and the plurality of cutting portions all extend downward to form a receiving gap; an annular slot is formed on the liquid injection member, and when the liquid injection member seals the lower end of the through groove, the plurality of cutting portions are all located in the annular slot.

[0022] By adopting the above technical solution, the arrangement of the cutting portions can cut long curved waste chips. For example, when the drilling member drills a hole, the drilling member discharges the waste chips outward. The waste chips may be in the shape of a long and curved one, and this waste chip will rotate together with the rotation of the drilling member. If not processed, it is easy to cause splashing. Therefore, by using the arrangement of the cutting portions, when this waste chip contacts the cutting portions, it can be cut off, thus avoiding the formation of this long waste chip. After the waste chip is cut off, the cut waste chip directly falls down without splashing, preventing the situation where the splashing waste chips rub against the gear, and preventing the situation where the splashing waste chips may hurt the staff. At the same time, it also prevents the splashing of waste chips, which ultimately makes it difficult to clean the waste chips, and better improves the safety of the drilling process and the convenience of later cleaning.

[0023] Optionally, the power component is used to drive the liquid injection member to rotate around a fixed axis so that the liquid injection member seals or opens the lower end of the through groove; or the power component is used to drive the liquid injection member to translate horizontally so that the liquid injection member seals 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 cutting portions are formed below the liquid injection member, and the plurality of cutting portions all extend downward and form a receiving gap.

[0024] By adopting the above technical solution, since the power component drives the liquid injection member to move, the cutting portions cannot be installed at the lower end of the through groove. Therefore, installing the cutting portions at the lower end of the liquid injection member can cut long waste chips, improving the safety of the drilling process and the convenience of later cleaning.

[0025] By adopting the above technical solution, after the liquid injection member opens the lower end of the through groove, the liquid injection member is away from the through groove. Therefore, the liquid injection member is away from the drilling member. A cutting portion is arranged at a position away from the drilling member to cut long waste chips at a position away from the drilling member. Thus, after the waste chip is cut, even if it is not cut off, it is easy to bend. If the cutting portion is too close to the drilling member, when the waste chip is not cut off, the bending of the waste chip will exert a large force on the cutting portion, easily accelerating the passivation of the cutting portion and easily affecting the normal outward discharge of the waste chips by the drilling member. Therefore, by arranging the cutting portion at a position away from the through groove, the quality and efficiency of waste chip treatment are better guaranteed.

[0026] Optionally, a contact portion with a flat surface is formed below the cutting portion. When the cleaning member moves downward to be close to the gear to be drilled, the flat surface of the contact portion abuts against the end surface of the gear to be drilled.

[0027] By adopting the above technical solution, the setting of the abutting part can prevent the cutting part from contacting the gear to be drilled when the cleaning part moves downward, thereby protecting the gear to be drilled and the cutting part.

[0028] Optionally, a connecting part is further formed below the cutting part, and the connecting part is used to connect the plurality of abutting parts; a clamping groove is formed in the liquid injection part, and the clamping groove is used to accommodate part or all of the cutting parts.

[0029] By adopting the above technical solution, the clamping groove accommodates part or all of the cutting parts. Then, when maintenance is required, all the cutting parts can be pushed into the clamping groove to prevent the cutting parts from leaking outside and posing a danger to maintenance personnel.

[0030] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] 1. The liquid injection part seals the through groove and injects the coolant into the through groove, and then the drilling part is located in the through groove. Therefore, the coolant cools the drilling part, and at the same time, a ductile steel brush is arranged in the through groove, which can play a role in cleaning the drilling part, realizing cleaning the drill bit immersed in the coolant and improving the effect of cleaning waste chips;

[0032] 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. Therefore, the coolant can be in a flowing state, timely discharging the waste chips in the through groove outward, and the flowing coolant and the steel brush and the drilling part generate a flowing impact force, which can better clean the drilling part and improve the effect of cleaning waste chips.

[0056] The following is further described in detail with reference to the attached Figures 1 - 15 to this application.

[0057] The embodiment of this application discloses a drilling machine for gear processing. Embodiment 1

[0058] A drilling machine for gear processing includes: a drilling member 1, a lifting drive member 2, a cleaning member 3, and a liquid injection member 4.

[0059] 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. When the drilling member 1 moves down, it drills the gear to be drilled. Among them, both the lifting drive member 2 and the drilling member 1 are installed on a drilling machine or form a drilling machine. A fixture for fixing the gear is provided on the base of the drilling machine. The fixture adopts the prior art and will not be elaborated. The cleaning member 3 forms a through groove 31 for the drilling member 1 to insert. A plurality of resilient steel brushes 32 are provided on the inner wall surface of the through groove 31. In this embodiment, the cleaning member 3 adopts a pipe body. The through groove 31 is the inner cavity of the pipe body. The resilient steel brush 32 is a resilient and soft steel brush. The steel brush can extend 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 beneficial for the waste chips to separate from the steel brushes.

[0060] The liquid injection member 4 is movably connected to the cleaning member 3 so that the liquid injection member 4 can block the lower end of the through groove 31 or open the lower end of the through groove 31. An injection groove 41 for external coolant is formed on the liquid injection member 4, so that when the liquid injection member 4 blocks the lower end of the through groove 31, the coolant is injected into the through groove 31. The liquid injection member 4 is a plate body. One end of the injection groove 41 is opened on the side of the liquid injection member 4, and the other end is opened at the end of the liquid injection member 4. The injection groove 41 is externally connected to a coolant device through a hose, so that the coolant is added to the through groove 31.

[0061] Wherein, when the end of the drilling member 1 moves upward or downward to the through slot 31, the liquid injection member 4 seals the lower end of the through slot 31, and the resilient steel brush 32 abuts against the drilling member 1. The through slot 31 is for the drilling member 1 to insert. Then, when the drilling member 1 moves downward, the liquid injection member 4 seals the lower end of the through slot 31 and injects the coolant into the through slot 31. The drilling member 1 is in immersion contact with the coolant. Then, the coolant contacts the drilling member 1 more evenly, which is beneficial to the downward movement of the coolant wrapped on the surface of the drilling member 1. Then, the liquid injection member 4 opens the lower end of the through slot 31, and all the coolant in the through slot 31 falls onto the gear to be drilled. The drilling member 1 penetrates through the through slot 31 and moves downward to contact the gear to be drilled for drilling, so as to ensure that there is enough coolant before the drilling member 1 drills, which is beneficial to improving the drilling quality.

[0062] When the drilling of the drilling member 1 is completed, the drilling member 1 moves upward and will first reach the through slot 31. Since the waste chips generated by drilling will be carried outwards when the drilling member 1 moves upward, the waste chips are likely to form a relatively long curved body, and the way of entering the through slot 31 by drilling can be used to block the waste chips and separate them from the drilling member 1. After the drilling member 1 enters the through slot 31, the cleaning member 3 seals the lower end of the through slot 31, and then the coolant is injected into the through slot 31. The drilling member 1 is immersed in the coolant to cool the drilling member 1, which is beneficial to the quality of the next drilling. Fine waste chips will adhere to the drilling member 1. The drilling member 1 is immersed in the coolant, and the coolant will overflow outwards at the upper end of the through slot 31. Thus, the coolant is in a flowing state, which is beneficial to separating the waste chips on the drilling member 1 from the drilling member 1. In addition, when the drilling member 1 rotates slowly in the through slot 31, there will be a relative movement with the coolant, and the inertial effect is more beneficial to separating the waste chips on the drilling member 1 from the drilling member 1. During the upward movement of the drilling member 1, it will also contact the resilient steel brush 32. The resilient steel brush 32 cleans the waste chips adhering to the drilling member 1 and cooperates with the outward overflow of the coolant, which can better separate the waste chips from the drilling member 1 and discharge the waste chips out of the through slot 31 along with the coolant, improving the cleaning and cooling effect on the drilling member 1. At the same time, it can also prevent the coolant from splashing strongly on the drilling member 1.

[0063] 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

[0064] 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.

[0065] 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

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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

[0070] 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 .

[0071] In one solution, the connection chamber 34 is externally connected to a gas source and the liquid injection tank 41. An outlet communicating with the liquid injection tank 41 is further formed on the liquid injection member 4. When the liquid injection member 4 seals the cleaning member 3, the outlet communicates with the connection chamber 34. The connection chamber 34 is provided with a plurality of circular holes, and the outlet communicates with some of the circular holes. An air injection hole is further formed on the cleaning member 3, and some of the other circular holes communicate with the air injection hole. The air injection hole is externally connected to an air pump through a hose. The air pump causes the gas to be injected into the through groove 31 in sequence through the hose, the air injection hole, the connection chamber 34 and the discharge port. Thus, the coolant can be discharged outwards at the discharge port, or the air can be discharged at the discharge port. Among them, the opening direction of the discharge port is inclined upwards or downwards. Therefore, it can better impact on the resilient steel brush 32 or the drilling member 1. With the arrangement of the discharge holes 35, the coolant can also be discharged outwards through the discharge holes 35, so that the coolant will generate a greater impact force on the resilient steel brush 32, which is more conducive to the removal of waste chips from the resilient steel brush 32. At the same time, it will also generate a greater impact on the drilling member 1, which is also conducive to the removal of waste chips from the drilling member 1. Connecting the connection chamber 34 to an external gas source can also inject air 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 resilient steel brush and the drilling member 1.

[0072] In another solution, the connection chamber 34 is externally connected to a gas source. The connection chamber 34 is provided with a plurality of circular holes. An air injection hole is further formed on the cleaning member 3. The connection chamber 34 communicates with the air injection hole. The air injection hole is externally connected to an air pump through a hose. The air pump causes the gas to be injected into the through groove 31 in sequence through the hose, the air injection hole, the connection chamber 34 and the discharge port.

[0073] In another solution, the connection chamber 34 is externally connected to the liquid injection tank 41. An outlet communicating with the liquid injection tank 41 is further formed on the liquid injection member 4. When the liquid injection member 4 seals the cleaning member 3, the outlet communicates with the connection chamber 34.

[0074] In another solution, the connection chamber 34 is externally connected to the coolant. A liquid injection pipe body capable of spraying the coolant outwards is inserted into the cleaning member 3 to communicate with the connection chamber 34. Embodiment 5

[0075] The difference between Example 5 and Example 1 lies in that: the drilling machine for gear processing further includes a power component 6, which is used to drive the cleaning component 3 to move up and down and drive the liquid injection component 4 to block or open the lower end of the through groove 31. The power component 6 includes: a crossbeam bracket 61, a lifting linear motor, a coupling plate 63 and a first driving motor. The liquid injection component 4 is rotatably connected to the cleaning component 3, and the axis of rotation of the liquid injection component 4 and the cleaning component 3 is perpendicular to the axis of the through groove 31. The crossbeam bracket 61 is arranged on the base, the lifting linear motor is installed on the crossbeam bracket 61, and the coupling plate 63 connects the output end of the lifting linear motor to the cleaning component 3, so as to drive the cleaning component 3 to move up and down by using the lifting linear motor. The first driving motor is installed on the coupling plate 63. The first driving motor is used to drive the liquid injection component 4 to rotate relative to the cleaning component 3, so as to block or open the lower end of the through groove 31. In some other solutions, the lifting linear motor is replaced by a first electric push rod 62.

[0076] When the drilling component 1 moves down and inserts into the through groove 31, the cleaning component 3 moves down to be close to the gear to be drilled and the power component 6 drives the liquid injection component 4 to open the lower end of the through groove 31; when the drilling component 1 moves up into the through groove 31, the power component 6 drives the liquid injection component 4 to block the lower end of the through groove 31, and the cleaning component 3 moves up away from the gear to be drilled. The power component 6 driving the cleaning component 3 to move up and down can make the drilling component 1 more located in the through groove 31, thereby increasing the process of the drilling component 1 being cooled by the coolant. In addition, when the cleaning component 3 moves down to be close to the gear to be drilled, during drilling, the waste chips discharged outward by the drilling component 1 can be better blocked by the cleaning component 3 or the opened liquid injection component 4, having the effect of preventing the waste chips from splashing outward randomly.

[0077] Specifically, a plurality of cutting portions 7 are formed at the lower end of the through groove 31. The plurality of cutting portions 7 all extend downward and form a receiving gap 71 for waste chips to enter. The cutting portion 7 is a cutting tool. An annular slot is formed on the liquid injection member 4. When the liquid injection member 4 seals the lower end of the through groove 31, the plurality of cutting portions 7 are all located in the annular slot. The arrangement of the cutting portions 7 can cut long curved waste chips. For example, when the drilling member 1 drills a hole, the drilling member 1 discharges the waste chips outwards. The waste chips may be in the shape of a long and curved strip, and this waste chip will rotate together with the rotation of the drilling member 1. If not processed, it is easy to cause splashing. Therefore, by using the arrangement of the cutting portions 7, when this waste chip contacts the cutting portions 7, it can be cut off, thus avoiding the formation of this long waste chip. After the waste chip is cut off, the cut waste chip directly falls down without splashing, preventing the situation where the splashing waste chip rubs against the gear, and preventing the situation where the splashing waste chip may hurt the staff. At the same time, it also prevents the splashing of waste chips, which ultimately makes it difficult to clean the waste chips, and better improves the safety of the drilling process and the convenience of later cleaning. Embodiment 6

[0078] The difference between Embodiment 6 and Embodiment 5 is that: the power component 6 is used to drive the liquid injection member 4 to rotate around a fixed axis, so that the liquid injection member 4 seals or opens the lower end of the through groove 31. The direction of the fixed axis matches the extension direction of the through groove 31; a plurality of cutting portions 7 are formed below the liquid injection member 4. The plurality of cutting portions 7 all extend downward and form a receiving gap 71. The power component 6 includes a second driving motor, and the second driving motor drives the liquid injection member 4 to rotate around the fixed axis. At this time, the liquid injection member 4 rotates closely against the lower end of the cleaning member 3. After the liquid injection member 4 opens the lower end of the through groove 31, the liquid injection member 4 is away from the through groove 31. Therefore, the liquid injection member 4 is away from the drilling member 1. A cutting portion 7 is arranged at a position away from the drilling member 1 to cut the long waste chips at a position away from the drilling member 1. Thus, after the waste chips are cut, even if they are not cut off, they are easy to bend. If the cutting portion 7 is too close to the drilling member 1, when the waste chips are not cut off, the bending of the waste chips will cause a large force on the cutting portion 7, which is easy to accelerate the passivation of the cutting portion 7 and is easy to affect the normal discharge of the waste chips by the drilling member 1. Therefore, by arranging the cutting portion 7 at a position away from the through groove 31, the quality and efficiency of waste chip treatment are better guaranteed.

[0079] In another solution, the power component 6 is used to drive the liquid injection component 4 to translate horizontally, so that the liquid injection component 4 blocks or opens the lower end of the through groove 31. Among them, the power component 6 includes a second electric push rod 64. Another solution of the liquid injection component 4 is that the liquid injection component 4 is composed of two semi-circular plate bodies, and two second electric push plates are provided to drive the two semi-circular plate bodies to approach and move away from each other. The liquid injection groove 41 is formed in one of the semi-circular plate bodies or in both of the semi-circular plate bodies.

[0080] Preferably, the liquid injection groove 41 is formed in both of the semi-circular plate bodies. For the convenience of description, the semi-circular plate body is defined as the moving plate 42. The liquid inlet end of the liquid injection groove 41 is on the arc side surface of the moving plate 42, and the liquid inlet end is externally connected to the coolant. The liquid outlet end of the liquid injection groove 41 is at the center of the arc side surface of the moving plate 42. Therefore, when the two moving plates 42 are butted together, the coolant will discharge the coolant upward into the through groove 31 at the center of the liquid injection component 4. Then, when the two moving plates 42 move away from each other, the liquid injection groove 41 will discharge the coolant outward in a parabolic manner and make the coolant fall on the gear to be drilled. By controlling the injection speed of the coolant, the coolant can fall on the drilling component 1, and then the coolant enters the hole being drilled along the drilling component 1, which can also achieve the effect of cooling the drilling component 1.

[0081] The liquid injection component 4 is symmetrically located on both sides of the cleaning component 3. Therefore, the cutting part 7 is also symmetrically located on both sides of the cleaning component 3, and the effect of cutting off the waste chips is better.

[0082] In some other embodiments, a contact part 72 with a flat surface is formed below the cutting part 7. The contact part 72 is a plate body. When the cleaning component 3 moves down to be close to the gear to be drilled, the flat surface of the contact part 72 contacts the end surface of the gear to be drilled. The setting of the contact part 72 can prevent the cutting part 7 from contacting the gear to be drilled when the cleaning component 3 moves down, so as to protect the gear to be drilled and the cutting part 7.

[0083] In some other embodiments, a connecting part 73 is further formed below the cutting part 7. The connecting part 73 is used to connect the plurality of contact parts 72. A clamping groove 74 is formed in the liquid injection component 4. The clamping groove 74 is used to accommodate part of the cutting part 7 or all of the cutting part 7. The clamping groove 74 accommodates part of the cutting part 7 or all of the cutting part 7. Then, when maintenance is needed, the cutting part 7 can be completely pushed into the clamping groove 74 to prevent the cutting part 7 from leaking outside and causing danger to maintenance personnel. The connecting part 73 facilitates pushing the plurality of cutting parts 7 into the clamping groove 74 at the same time.

[0084] The implementation principle of a drilling machine for gear processing in the embodiment of the present application is as follows:

[0085] The drilling member 1 moves downward from the uppermost position. The drilling member 1 is inserted into the blocked through groove 31. The liquid 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 liquid injection member 4 move downward together with the drilling member 1. When the cleaning member 3 and the liquid injection member 4 are close to the gear to be drilled, the driving member drives the liquid injection member 4 to open the lower end of the through groove 31, and a large amount of the coolant in the through groove 31 falls on the gear to be drilled. After the cleaning member 3 and the liquid injection member 4 continue to move downward until the abutting portion 72 abuts against the gear to be drilled, the cleaning member 3 and the liquid 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.

[0086] After the drilling of the drilling member 1 is completed, the drilling member 1 moves upward. The drilling member 1 moves upward into the through groove 31. Then the driving member drives the cleaning member 3 to move upward, and the liquid injection member 4 moves to block the lower end of the through groove 31. The drilling member 1 is located in the through groove 31, and the cleaning member 3 moves upward together with the drilling member 1, so that the drilling member 1 moves to be located in the through groove 31. The drilling member 1 rotates in the through groove 31, and the resilient steel brush 32 contacts the drilling member 1. The liquid injection member 4 continuously adds coolant into the through groove 31 and causes the coolant to overflow outward at the upper end of the through groove 31, so as to improve the effect of cleaning the waste chips on the drilling member 1.

[0087] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
