Description

Technical Field

[0001] The present invention relates to the technical field of tapping machines, and particularly to a tapping machine for bolt processing. Background Art

[0002] A bolt tapping machine is a special device for processing internal threads on bolts, mainly composed of a machine body, a power system, a clamping and positioning device, a tapping execution mechanism, and a cooling and chip removal system. The cooling and chip removal system is used to spray coolant on the tap during tapping, thereby reducing the cutting temperature and prolonging the life of the tap.

[0003] The iron chips generated during tapping will flow back into the collection box along with the dripping coolant on the diversion groove. The iron chips carried by the coolant are preliminarily separated through a sieve or a filter screen to prevent debris from entering the circulation pump. Some devices install magnets at the bottom of the collection box to adsorb metal chips, or set up a multi-stage filtration system for step-by-step interception in order to improve the separation efficiency. However, the above separation methods have the following problems: After long-term use, the surface of the magnet is saturated with adsorption, resulting in ineffective subsequent adsorption of iron chips, and even the adsorbed iron chips falling off due to magnetic force attenuation. Due to the aperture limitation of the filter screen in the multi-stage filtration system, large-particle iron chips will block on the filter screen, affecting the interception and filtration range of the filter screen, while small-particle iron chips can directly pass through the filter screen. After the iron chips are mixed with the coolant again, they will not only impact the fan blades of the circulation pump and cause wear, but also block the coolant nozzle, resulting in a reduced spray cooling effect on the tap. Summary of the Invention

[0004] In view of the problem that the existing filtration system is difficult to continuously and effectively intercept and separate the iron chips generated after tapping, a tapping machine for bolt processing is proposed.

[0005] Its purpose is: After the iron chips are diverted into the precipitation pipe and accumulate in the transfer part, the flow of the coolant drives the transfer part to rotate intermittently, and the accumulated iron chips are transferred into the collection bucket, realizing the continuous and effective separation of the iron chips from the coolant.

[0006] The technical solution of the present invention is a tapping machine for bolt processing, including a tapping machine main body. A diversion groove is connected to the working table of the tapping machine main body. A collection box is provided on the lower side of the lowest end of the diversion groove. A fixed box is fixedly installed on the top surface of the collection box. A slow-flow plate is fixedly connected to the upper part of the fixed box and is inclined. The bottom of the fixed box on one side of the lowest end of the slow-flow plate is communicated with the collection box. A leakage hole is opened in the middle of the slow-flow plate. An intercepting plate fixedly connected to the slow-flow plate is provided on one side of the leakage hole. A precipitation pipe is fixedly connected to the bottom of the leakage hole. A sewage cleaning mechanism is arranged on the lower side of the precipitation pipe;

[0007] The dirt cleaning mechanism includes a transfer member rotatably connected to the bottom of the flow slowing plate. The transfer member is of a cylindrical structure. The arc surface of the transfer member is in abutting fit with the lower end of the sedimentation pipe. A plurality of transfer grooves are provided on the transfer member at equal intervals in a circular shape. A collection bucket is provided below the transfer member, and the collection bucket is placed at the bottom of the fixed box;

[0008] One side of the lowest end of the flow slowing plate is provided with a waterwheel rotatably connected to the fixed box. A transmission member is commonly connected between the waterwheel and the dirt cleaning mechanism. Iron filings flow into the sedimentation pipe and accumulate in the transfer grooves with the openings facing upward. The coolant drives the waterwheel to rotate. The waterwheel drives the transfer member to rotate through the transmission member. After the opening of the transfer groove filled with iron filings faces downward, the iron filings flow into the collection bucket.

[0009] With the above technical solution, the iron filings and coolant generated after the tapping machine body taps the bolt flow through the diversion groove to the highest end of the flow slowing plate. The coolant slowly flows along the inclined surface of the flow slowing plate. The iron filings accumulate on the flow slowing plate under the obstruction of the intercepting plate. The flow of the coolant drives the iron filings to move into the sedimentation pipe through the leakage holes. The liquid flow rate in the sedimentation pipe decreases, so that the iron filings precipitate and accumulate in the transfer grooves with the openings facing upward. After the coolant leaves the flow slowing plate, it flows into the water tank of the waterwheel. The waterwheel rotates and drives the transfer member to rotate intermittently through the transmission member, so that all the transfer grooves are sequentially in abutting connection with the lower port of the sedimentation pipe. When the opening of the transfer groove filled with iron filings faces downward, it drives the iron filings to flow into the collection bucket, realizing the separation of the iron filings and the coolant.

[0010] Further, a diversion pipe is fixedly connected to the bottom of the diversion groove, and the lower port of the diversion pipe is arranged above the highest end of the flow slowing plate.

[0011] With the above technical solution, a plurality of through holes penetrating up and down are opened at the bottom of the diversion groove. The gap of the through holes is smaller than the size of the bolt. The processed bolt falls onto the diversion groove and moves downward along the inclined surface of the diversion groove. The coolant and iron filings flow into the diversion pipe through the through holes and flow to the top surface of the highest end of the flow slowing plate through the diversion pipe.

[0012] Further, the intercepting plate is of a V-shaped structure. The middle part of the intercepting plate is arranged toward one side of the lowest end of the flow slowing plate, and an arc-shaped concave surface is arranged at the lower part of the side of the intercepting plate facing the highest end of the flow slowing plate.

[0013] With the above technical solution, the intercepting plate intercepts the moving iron filings. The coolant continues to flow downward to the lower end of the flow slowing plate after overflowing the intercepting plate. At the same time, under the guidance of the intercepting plate, the coolant at the bottom layer moves toward the middle, driving the accumulated iron filings to move toward the leakage holes. The setting of the arc-shaped concave surface avoids the generation of dead corners between the intercepting plate and the flow slowing plate. At the same time, it can improve the smoothness of the coolant moving along the intercepting plate direction, improve the moving efficiency of the coolant driving the iron filings to the leakage holes, and avoid the accumulation of iron filings.

[0014] Further, a rotating seat is rotatably connected to one side of the transfer member, the rotating seat is fixedly connected to the bottom of the flow retarder plate, a guide cover with a superior arc structure is sleeved outside the transfer member, one side of the guide cover is fixedly connected to the rotating seat, and the lowest end of the guide cover is fixedly communicated with an extension pipe.

[0015] With the above technical solution, after the iron filings accumulate to a certain extent in the transfer groove, the transfer member rotates by a certain angle, so that the opening of the transfer groove containing the iron filings faces downward. The iron filings follow the flow of the coolant into the guide cover and flow downward through the extension pipe into the collection bucket under the limitation of the guide cover.

[0016] Further, the transfer groove has a T-shaped structure, and a T-shaped block is slidably connected in the transfer groove.

[0017] With the above technical solution, when the opening of the transfer groove faces downward and is in a non-vertical state, the T-shaped block slides toward the opening of the transfer groove under the action of gravity, and can push the iron filings and coolant in the transfer groove to sink to the bottom and be discharged, avoiding some iron filings remaining on the inner wall of the transfer groove. When the opening of the transfer groove faces upward and is in a non-vertical state, the T-shaped block returns to the bottom of the transfer groove again.

[0018] Further, the transmission member includes a transmission gear fixedly connected to one side of the transfer member, a sector gear is meshed with one side of the transmission gear, both the transmission gear and the sector gear are rotatably connected to the fixed box, and a chain is commonly connected between the sector gear and the waterwheel.

[0019] With the above technical solution, the waterwheel includes a rotating shaft rotatably connected to the fixed box, and a plurality of water troughs are fixedly connected at equal intervals on the arc-shaped outer wall of the rotating shaft. After the coolant leaves the flow retarder plate, it flows into one of the water troughs of the waterwheel. When the gravity of the water trough is greater than the rotation resistance of the transfer member, the waterwheel drives the sector gear to rotate through the chain. When the tooth part of the sector gear meshes with the transmission gear, it drives the transfer member to rotate by a certain angle, changing the position of the transfer groove.

[0020] Further, a liquid discharge assembly is provided in the collection bucket. The liquid discharge assembly includes a fixed pipe vertically and fixedly penetrating through the bottom of the collection bucket. A guide pipe is slidably connected in the fixed pipe. The upper end of the guide pipe passes through the fixed pipe and is fixedly connected to a buoyancy chamber with a cavity structure. A plurality of through holes communicating with the cavity are opened at the bottom of the buoyancy chamber. A telescopic pipe is provided in the guide pipe. The lower end of the telescopic pipe is fixedly connected to the lower end of the fixed pipe, and the upper end of the telescopic pipe is fixedly communicated with one of the through holes;

[0021] The lower end of the fixed pipe movably penetrates through the bottom of the fixed box and extends into the collection box.

[0022] With the above technical solution, the iron filings and coolant after leaving the fairing accumulate in the collection bucket. When the iron filings accumulate to a certain height, the liquid level of the coolant contacts the bottom surface of the buoyancy chamber. The through holes on the bottom surface of the buoyancy chamber allow the coolant to enter the interior of the buoyancy chamber and flow downward through the telescopic pipe into the collection box, thereby discharging the excess coolant in the collection bucket and improving the recycling rate of the coolant. Among them, the fixed pipe and the guiding pipe are slidably matched to limit the vertical movement of the buoyancy chamber. As the iron filings gradually increase in the collection bucket, the buoyancy chamber rises synchronously with the liquid level, realizing the discharge of the excess coolant in the collection bucket.

[0023] Further, the buoyancy chamber has a frustum-shaped structure, and a collection hopper is fixedly connected to the top of the buoyancy chamber. The collection hopper is vertically coaxially arranged with the extension pipe, and a plurality of liquid discharge holes are opened at equal intervals in a ring shape at the lower end of the collection hopper.

[0024] With the above technical solution, the inner diameter of the upper port of the collection hopper is larger than the inner diameter of the lower port of the extension pipe. The collection hopper receives the iron filings and coolant discharged by the transfer member, and evenly distributes them onto the inclined surface of the buoyancy chamber through a plurality of liquid discharge holes, making the surface of the iron filings relatively flat when they accumulate in the collection bucket, which helps the buoyancy chamber to more effectively discharge the excess coolant.

[0025] Further, a flow splitting assembly is provided on the side of the leakage hole away from the intercepting plate. The flow splitting assembly includes a fixing plate fixedly connected to the top surface of the slow flow plate. A flow splitting plate is fixedly connected to the top surface of the fixing plate. A flow splitting inclined surface is provided on the top surface of the flow splitting plate, and one end of the flow splitting plate extends above the intercepting plate.

[0026] With the above technical solution, the fixing plate provides a certain gap between the flow splitting plate and the top surface of the slow flow plate. The right end of the flow splitting plate is located in the middle of the coolant liquid level, so that the upper and middle layer liquids in the coolant directly flow across the intercepting plate and continue to flow downward through the flow splitting inclined surface. The gap between the bottom surface of the flow splitting plate and the top surface of the slow flow plate allows the iron filings and the lower layer liquid to flow, realizing the splitting of the coolant, which can reduce the liquid level height on the slow flow plate, making it easier for the iron filings to be intercepted by the intercepting plate and avoiding some iron filings following the coolant across the intercepting plate due to the higher liquid level height.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. By using the gravity difference between the coolant and the iron filings when they flow on the slow flow plate to achieve stratification, the iron filings flow into the precipitation pipe under the interception of the intercepting plate, so that the iron filings can precipitate and accumulate in the transfer groove. Under the intermittent rotation of the transfer member, the iron filings in the transfer groove move into the collection bucket, completing the continuous and effective separation of the iron filings and the coolant.

[0029] 2. Immerse the bottom of the buoyancy chamber into the coolant in the collection bucket, allowing the coolant to enter the buoyancy chamber through the through-holes at the bottom of the buoyancy chamber and be discharged into the collection box through the telescopic pipe, so as to discharge the excess coolant in the collection bucket, reduce the waste of coolant, and improve the recycling rate of coolant.

[0030] 3. Make the coolant flow in layers through the flow splitter plate, which can reduce the liquid level height on the flow retarder plate, improve the interception effect of the interception plate on iron filings, and prevent some iron filings from following the coolant across the interception plate due to the high liquid level height, further improving the separation effect.

[0045] To make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the accompanying drawings of the specification.

[0046] Example 1, referring to Figures 1-8 , which is the first embodiment of the present invention, provides a tapping machine for bolt processing, including a tapping machine main body 1. A flow guiding groove 2 is connected to the working table of the tapping machine main body 1. A collection box 3 is provided below the lowest end of the flow guiding groove 2. A fixed box 5 is fixedly installed on the top surface of the collection box 3. A flow slowing plate 6 inclinedly arranged is fixedly connected to the upper part inside the fixed box 5. The bottom of the fixed box 5 on one side of the lowest end of the flow slowing plate 6 is communicated with the collection box 3. A leakage hole 61 is opened in the middle of the flow slowing plate 6. An intercepting plate 7 fixedly connected to the flow slowing plate 6 is provided on one side of the leakage hole 61. A precipitation pipe 8 is fixedly connected to the bottom of the leakage hole 61. A cleaning mechanism 9 is arranged below the precipitation pipe 8; the cleaning mechanism 9 includes a transfer part 91 rotatably connected to the bottom of the flow slowing plate 6. The transfer part 91 has a cylindrical structure. The arc surface of the transfer part 91 abuts and cooperates with the lower end of the precipitation pipe 8. A plurality of transfer grooves 92 are opened on the transfer part 91 at equal intervals in a circular shape. A collection bucket 95 is provided below the transfer part 91. The collection bucket 95 is placed at the bottom of the fixed box 5; A waterwheel 10 rotatably connected to the fixed box 5 is provided on one side of the lowest end of the flow slowing plate 6. A transmission part 11 is commonly connected between the waterwheel 10 and the cleaning mechanism 9. The iron filings flow into the precipitation pipe 8 and accumulate in the transfer grooves 92 with the opening facing upward. The coolant drives the waterwheel 10 to rotate. The waterwheel 10 drives the transfer part 91 to rotate through the transmission part 11. After the opening of the transfer groove 92 filled with iron filings faces downward, the iron filings flow into the collection bucket 95.

[0047] Specifically, the iron filings and coolant generated after the tapping machine main body 1 finishes tapping the bolts flow through the diversion groove 2 to the highest end of the flow retarder plate 6. The coolant slowly flows along the inclined surface of the flow retarder plate 6. The iron filings are blocked by the intercepting plate 7 and accumulate on the flow retarder plate 6. The flowing coolant drives the iron filings to move into the precipitation pipe 8 through the leakage holes 61. The liquid flow rate in the precipitation pipe 8 decreases, causing the iron filings to precipitate and accumulate in the upward-opening transfer groove 92. After leaving the flow retarder plate 6, the coolant flows into the water tank of the waterwheel 10. The waterwheel 10 rotates and drives the transfer member 91 to rotate intermittently through the transmission member 11, so that all the transfer grooves 92 are successively abutted against the lower port of the precipitation pipe 8. When the opening of the transfer groove 92 filled with iron filings faces downward, it drives the iron filings to flow into the collection bucket 95, realizing the separation of iron filings and coolant.

[0048] Among them, after the iron filings flow into the precipitation pipe 8, the internal environment of the precipitation pipe 8 is less affected by the liquid flow. Therefore, the iron filings inside the precipitation pipe 8 can gradually precipitate downward. The opening of the upward-opening transfer groove 92 communicates with the lower port of the precipitation pipe 8, and finally the iron filings accumulate in the transfer groove 92.

[0049] Refer to Figures 2-3 , a diversion pipe 4 is fixedly connected to the bottom of the diversion groove 2, and the lower port of the diversion pipe 4 is arranged above the highest end of the flow retarder plate 6.

[0050] Specifically, a plurality of through holes penetrating up and down are opened at the bottom of the diversion groove 2, and the gap of the through holes is smaller than the size of the bolt. The processed bolts fall onto the diversion groove 2 and move downward along the inclined surface of the diversion groove 2. The coolant and iron filings flow into the diversion pipe 4 through the through holes and flow to the top surface of the highest end of the flow retarder plate 6 through the diversion pipe 4.

[0051] Refer to Figure 4 , the intercepting plate 7 is in a V-shaped structure, the middle of the intercepting plate 7 is arranged on the side facing the lowest end of the flow retarder plate 6, and an arc-shaped concave surface 71 is arranged at the lower part of the side of the intercepting plate 7 facing the highest end of the flow retarder plate 6.

[0052] Specifically, the intercepting plate 7 intercepts the moving iron filings. The coolant continues to flow downward to the lower end of the flow retarder plate 6 after overflowing the intercepting plate 7. At the same time, under the guidance of the intercepting plate 7, the coolant at the bottom layer moves toward the middle, driving the accumulated iron filings to move toward the leakage holes 61. The setting of the arc-shaped concave surface 71 avoids the generation of dead corners between the intercepting plate 7 and the flow retarder plate 6. At the same time, it can improve the smoothness of the coolant moving along the direction of the intercepting plate 7, improve the moving efficiency of the coolant driving the iron filings toward the leakage holes 61, and avoid the accumulation of iron filings.

[0053] It is understandable that the gravity of the iron filings is greater than that of the coolant. Therefore, when the coolant carrying the iron filings moves on the flow retarder plate 6, the iron filings gradually move downward to the top surface of the flow retarder plate 6 and gradually move under the scouring of the coolant. The movement of the iron filings is intercepted by the interception plate 7. After the coolant level rises above the top surface of the interception plate 7, the coolant can overflow the interception plate 7 and continue to flow downward.

[0054] Referring to Figure 7 , a rotating seat is rotatably connected to one side of the transfer member 91, and the rotating seat is fixedly connected to the bottom of the flow retarder plate 6. A guide cover 94 with a U-shaped structure is sleeved outside the transfer member 91. One side of the guide cover 94 is fixedly connected to the rotating seat, and an extension pipe 96 is fixedly communicated with the lowest end of the guide cover 94.

[0055] Specifically, after the iron filings are accumulated in the transfer groove 92 to a certain extent, the transfer member 91 rotates by a certain angle, so that the opening of the transfer groove 92 containing the iron filings faces downward. The iron filings flow along with the coolant into the guide cover 94 and flow downward through the extension pipe 96 into the collection bucket 95 under the limitation of the guide cover 94.

[0056] Among them, an arc-shaped opening adapted to the arc surface of the transfer member 91 is provided on the lower end surface of the sedimentation pipe 8. When the transfer member 91 rotates, the surface of the arc-shaped opening has a sliding friction with the arc surface of the transfer member 91, and the sedimentation pipe 8 is made of rubber material, which can increase the connection tightness with the transfer member 91 and avoid leakage when the transfer member 91 rotates.

[0057] Referring to Figure 7 , the transfer groove 92 has a T-shaped structure, and a T-shaped block 93 is slidably connected in the transfer groove 92.

[0058] Specifically, when the opening of the transfer groove 92 faces downward and is in a non-vertical state, the T-shaped block 93 slides toward the opening of the transfer groove 92 under the action of gravity, and can push the iron filings and coolant in the transfer groove 92 to sink to the bottom and be discharged, avoiding partial iron filings remaining on the inner wall of the transfer groove 92. When the opening of the transfer groove 92 faces upward and is in a non-vertical state, the T-shaped block 93 returns to the bottom of the transfer groove 92 again.

[0059] Among them, the T-shaped block 93 is jointly composed of a rubber plug with a cavity structure and a solid metal counterweight. The rubber plug fits with the inner wall of the transfer groove 92. When the opening of the transfer groove 92 faces downward and is in a non-vertical state, the counterweight pushes the rubber plug to slide along the inner wall of the transfer groove 92, and completely pushes out the iron filings in the transfer groove 92.

[0060] Referring to Figures 5-6 , the transmission member 11 includes a transmission gear 111 fixedly connected to one side of the transfer member 91. A sector gear 112 is meshed with one side of the transmission gear 111. The transmission gear 111 and the sector gear 112 are both rotatably connected to the fixed box 5, and a chain 113 is jointly connected between the sector gear 112 and the waterwheel 10.

[0061] Specifically, the waterwheel 10 includes a rotating shaft rotatably connected to the fixed box 5. A plurality of water troughs are fixedly connected at equal intervals on the arc-shaped outer wall of the rotating shaft. After the coolant leaves the flow retarder plate 6, it flows into one of the water troughs of the waterwheel 10. When the gravity of the water trough is greater than the rotational resistance of the transfer member 91, the waterwheel 10 drives the sector gear 112 to rotate through the chain 113. When the tooth part of the sector gear 112 meshes with the transmission gear 111, it drives the transfer member 91 to rotate by a certain angle, causing the position of the transfer groove 92 to change.

[0062] Among them, every time the sector gear 112 rotates one circle, it drives the transmission gear 111 to rotate by a certain angle, so that the current transfer groove 92 moves to the position of the next transfer groove 92 in the rotation direction. And the transfer member 91 is connected to the rotating seat through a bearing. The transfer member 91 is made of plastic material, so as to reduce the self-gravity of the transfer member 91, enabling the waterwheel 10 to effectively drive the transfer member 91 to rotate.

[0063] It can be understood that a partition is fixedly connected between the lowest end of the flow retarder plate 6 and the fixed box 5. The waterwheel 10 is isolated through the partition, and the coolant is flow-guided to flow into the collection box 3.

[0064] Example 2, referring to Figures 8-9 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that a liquid discharge assembly 12 is provided in the collection bucket 95. The liquid discharge assembly 12 includes a fixed pipe 121 vertically and fixedly penetrating the bottom of the collection bucket 95. A guide pipe 122 is slidably connected in the fixed pipe 121. The upper end of the guide pipe 122 penetrates out of the fixed pipe 121 and is fixedly connected with a buoyancy chamber 123 having a cavity structure. A plurality of through holes communicating with the cavity are opened at the bottom of the buoyancy chamber 123. A telescopic pipe 124 is provided in the guide pipe 122. The lower end of the telescopic pipe 124 is fixedly connected to the lower end of the fixed pipe 121, and the upper end of the telescopic pipe 124 is fixedly communicated with one of the through holes; the lower end of the fixed pipe 121 movably penetrates the bottom of the fixed box 5, and the lower end of the fixed pipe 121 movably penetrates into the collection box 3.

[0065] Specifically, the iron filings and coolant after leaving the diversion cover 94 accumulate in the collection bucket 95. When the iron filings accumulate to a certain height, the coolant liquid level contacts the bottom surface of the buoyancy chamber 123. The through holes at the bottom surface of the buoyancy chamber 123 allow the coolant to enter the interior of the buoyancy chamber 123 and flow downward through the telescopic pipe 124 into the collection box 3, thereby completing the discharge of the excess coolant in the collection bucket 95 and improving the recycling rate of the coolant. Among them, the fixed pipe 121 and the guide pipe 122 are slidably matched to limit the vertical movement of the buoyancy chamber 123. As the iron filings gradually increase in the collection bucket 95, the buoyancy chamber 123 rises synchronously with the liquid level, realizing the discharge of the excess coolant in the collection bucket 95.

[0066] Among them, a heightening pipe is fixedly connected to the through hole in the buoyancy chamber 123 that is not connected to the telescopic pipe 124. Under the action of gravity, the bottom of the buoyancy chamber 123 sinks into the coolant, and the top surface height of the heightening pipe is lower than the liquid level. The coolant enters the buoyancy chamber 123 through the heightening pipe and is discharged downward through the telescopic pipe 124.

[0067] Referring to Figure 9 , the buoyancy chamber 123 has a frustum-shaped structure, and a collecting hopper 125 is fixedly connected to the top of the buoyancy chamber 123. The collecting hopper 125 is coaxially arranged vertically with the extension pipe 96, and a plurality of liquid discharge holes are opened at equal intervals in a ring shape at the lower end of the collecting hopper 125.

[0068] Specifically, the inner diameter of the upper port of the collecting hopper 125 is larger than the inner diameter of the lower port of the extension pipe 96. The collecting hopper 125 receives the iron filings and coolant discharged by the transfer member 91, and uniformly distributes them onto the inclined surface of the buoyancy chamber 123 through a plurality of liquid discharge holes, so that the surface of the iron filings is relatively flat when piled up in the collecting bucket 95, which helps the buoyancy chamber 123 to more effectively discharge the excess coolant.

[0069] Among them, the inclined surface of the buoyancy chamber 123 can also reduce the flow rate of the coolant and iron filings. At the same time, under the action of the uniform distribution of the inclined surface of the buoyancy chamber 123, the impact force of the flowing coolant on the inside of the collecting bucket 95 can be reduced, which helps the iron filings to accelerate precipitation in the collecting bucket 95 and avoid free movement and entering the buoyancy chamber 123. The rest of the structure is the same as that of Embodiment 1.

[0070] Embodiment 3, referring to Figures 10-11 , is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that a flow splitting component 13 is provided on the side of the leakage hole 61 away from the intercepting plate 7. The flow splitting component 13 includes a fixing plate 131 fixedly connected to the top surface of the flow buffering plate 6. A flow splitting plate 132 is fixedly connected to the top surface of the fixing plate 131. A flow splitting inclined surface 133 is provided on the top surface of the flow splitting plate 132, and one end of the flow splitting plate 132 extends above the intercepting plate 7.

[0071] Specifically, the fixing plate 131 provides a certain gap between the flow splitting plate 132 and the top surface of the flow buffering plate 6. The right end of the flow splitting plate 132 is located in the middle of the coolant liquid level, so that the upper and middle layer liquids in the coolant directly flow across the intercepting plate 7 through the flow splitting inclined surface 133 and continue to flow downward. The gap between the bottom surface of the flow splitting plate 132 and the top surface of the flow buffering plate 6 allows the iron filings and the lower layer liquid to flow, realizing the splitting of the coolant, so that the liquid level height on the flow buffering plate 6 can be reduced, making it easier for the iron filings to be intercepted by the intercepting plate 7 and avoiding some iron filings from following the coolant across the intercepting plate 7 due to the higher liquid level height.

[0072] Among them, referring to Figures 10-11, the fixed plate 131 is arranged on the right side of the leakage hole 61, and two inclined surfaces are symmetrically arranged on the right part. The leakage hole 61 can be blocked by the fixed plate 131 to prevent the coolant from directly flowing into the sedimentation pipe 8, and further reduce the influence of the water flow on the internal environment of the sedimentation pipe 8.

[0073] Refer to Figure 12 , the flow retarder plate 6 and the flow splitter plate 132 are inclined to the same side. The angle between the flow slope of the flow retarder plate 6 and the horizontal line is a, and the angle between the top surface of the flow splitting slope 133 and the horizontal line is b. The angle a is greater than the angle b. The rest of the structure is the same as that of the second embodiment.

[0074] Combining Embodiments 1-3, the working principle of the present invention is as follows: After the tapping machine main body 1 taps the bolt, the bolt slides down to the lower end through the diversion groove 2. The generated iron chips and coolant flow into the diversion pipe 4 through the through holes of the diversion groove 2 and flow above the highest end of the flow retarder plate 6. The coolant slowly flows along the inclined surface of the flow retarder plate 6. The iron chips are blocked by the intercepting plate 7 and accumulate on the flow retarder plate 6. The flow of the coolant drives the iron chips to move into the sedimentation pipe 8 through the leakage hole 61. The iron chips precipitate and accumulate in the transfer groove 92 with an upward opening. After leaving the flow retarder plate 6, the coolant flows into the water tank of the waterwheel 10. The waterwheel 10 rotates and drives the transfer member 91 to rotate intermittently through the transmission member 11. When the opening of the transfer groove 92 filled with iron chips faces downward, the iron chips flow into the collection hopper 125 through the diversion cover 94 and finally accumulate in the collection bucket 95 after sliding through the buoyancy chamber 123. The coolant in the collection bucket 95 enters through the through hole at the bottom surface of the buoyancy chamber 123 and is discharged into the collection box 3 through the telescopic pipe 124.

Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
