Rail transit embedded channel manufacturing drilling equipment and manufacturing process thereof

Abstract

This invention discloses a drilling device and its manufacturing process for manufacturing pre-embedded channels for rail transit, relating to the field of drilling. The drilling device for manufacturing pre-embedded channels for rail transit utilizes the cooperation between the arc-shaped protrusions on the opposite side of the convex strip and the inclined surface of the top of the fixed plate. When drilling while clamping the workpiece, the gap between the arc-shaped protrusions provides a clearance for the outflow of lubricating and cooling oil. Simultaneously, the inclined surface of the top of the fixed plate cooperates with the support strip. Taking advantage of the fact that the arc-shaped protrusion at the top of the support strip is higher than the center of the top of the fixed plate, a gap exists between the inclined surface of the fixed plate and the bottom of the workpiece during drilling, ensuring that the drill bit can smoothly penetrate the workpiece. At the same time, it provides support force to the fixed plate during drilling. Furthermore, the arc-shaped surface at the top of the support plate reduces the contact area with the bottom of the fixed plate, preventing drilling debris from entering the contact area and causing obstruction.

Description

Technical Field

[0001] This invention specifically relates to a drilling equipment and manufacturing process for manufacturing pre-embedded channels for rail transit, and pertains to the field of drilling. Background Technology

[0002] Drilling equipment for manufacturing embedded channels in rail transit refers to specialized CNC drilling equipment used for high-precision, high-volume processing of anchor bolt holes or rivet holes in cold-rolled channels. This type of equipment is the core hole processing equipment in the embedded channel production line.

[0003] A drilling device with publication number CN116079107B includes a controller and a drilling apparatus. The drilling apparatus includes a drill bit frame, a lifting guide column, a lifting frame, a depth positioning component, and a lifting drive assembly. The drill bit frame has a first lifting hole. The lifting guide column passes through the first lifting hole. The lifting frame is connected to the lifting guide column. Along the lifting direction, the depth positioning component is movably arranged relative to the lifting frame. A lifting sensor is disposed on the lifting frame. The lifting drive assembly is connected to the lifting frame. Both the lifting drive assembly and the lifting sensor are electrically connected to the controller, which is configured to control the lifting drive assembly to drive the lifting frame to rise based on a lifting limit signal. Therefore, the lifting guide column passing through the second lifting hole can guide the lifting of the lifting frame and improve the stress on the lifting frame during drilling, reducing the possibility of damage to the drilling apparatus.

[0004] In existing equipment, because the oil cannot flow at the clamping position when drilling the workpiece, the oil cannot carry the debris out along the clamping position and remains on the surface of the workpiece, unable to be carried away. At the same time, when the drill bit passes through the workpiece during drilling, it is damaged because there is no gap between the workpiece and the clamp. Summary of the Invention

[0005] To address the aforementioned problems, a technical solution is proposed: a drilling device for manufacturing pre-embedded channels for rail transit, comprising:

[0006] The frame has a slag collection mechanism fixedly installed on its top, a fixing mechanism installed inside the slag collection mechanism, a drill bit mechanism fixedly installed on the top of the frame, and a liquid collection tank fixedly installed on the outside of the frame. The liquid collection tank is connected to the slag collection mechanism through a pipe.

[0007] The fixing mechanism includes a fixing base with a sloping groove at the center of its top. A threaded rod is rotatably mounted on the inner wall of the fixing base, with both ends of the threaded rod penetrating the fixing base and extending to its outer side. Hexagonal heads are fixedly mounted on both ends of the threaded rod. Fixing plates are slidably mounted on both sides of the top of the fixing base. The tops of the fixing plates have a sloping surface protruding at their centers, and the opposite surfaces of the fixing plates have grooves. Supporting strips are fixedly mounted in the grooves of the fixing plates, and each support strip has an arc-shaped protrusion at its top, with the top of the arc-shaped protrusion higher than the top of the fixing plate. At the center of the surface, the top of the fixing plate is provided with convex strips on the opposite sides, and arc-shaped protrusions are fixedly installed on the opposite sides of the convex strips. The arc-shaped protrusions on the opposite sides of the convex strips cooperate with the inclined surface of the top of the fixing plate. When the workpiece is clamped for drilling, the gap between the arc-shaped protrusions provides a gap for the outlet of lubricating and cooling oil. At the same time, the inclined surface of the top of the fixing plate cooperates with the support strip. Taking advantage of the fact that the arc-shaped protrusion at the top of the support strip is higher than the center of the top of the fixing plate, there is a gap between the inclined surface of the fixing plate and the bottom of the workpiece when drilling the workpiece. This ensures that the drill bit can smoothly penetrate the workpiece during drilling. The arc-shaped protrusions are evenly installed on the opposite sides of the convex strips.

[0008] Preferably, each of the fixing plates has a screw hole block fixedly installed at its bottom. The inner wall of the screw hole block is threadedly connected to the outer side of the threaded rod. Support plates are fixedly installed on both sides of the inner wall of the fixing seat. The support plates are symmetrically installed along the center position of the axis of the fixing seat, and the top of the support plate is a convex arc surface. The arc surface of the top of the support plate contacts the bottom of the fixing plate, providing support force for the fixing plate during drilling. At the same time, the arc surface of the top of the support plate reduces the contact area with the bottom of the fixing plate, preventing drilling debris from entering the contact position and causing obstruction. The arc surface of the top of the support plate contacts the bottom of the fixing plate.

[0009] Preferably, the slag collection mechanism includes a connecting seat, a collection trough is fixedly installed on the top of the connecting seat, a guide pipe is fixedly installed on both sides of the bottom of the collection trough, a slag collection bin is fixedly installed at the bottom end of the guide pipe, the fixed seat is fixedly installed at the center position of the bottom of the inner wall of the collection trough, and a connecting pipe is fixedly installed on the outer side of the slag collection bin.

[0010] Preferably, a grating plate is fixedly installed on the inner wall of the slag collection bin. The center of the grating plate protrudes upward in an arc shape, and the top of the grating plate has evenly spaced grating grooves. A filter plate is fixedly installed on the inner wall of the slag collection bin. The filter plate is installed at an angle inside the slag collection bin. The arc-shaped protrusion of the grating plate cooperates with the filter plate, and the arc-shaped protrusion of the grating plate cooperates with the grating grooves to move the blocked large debris to both sides, avoiding obstruction at the center. This ensures that the grating grooves can smoothly filter out large debris from the oil. At the same time, the angled installation of the filter plate keeps the filtered large debris away from the oil outlet of the connecting pipe, avoiding... A large amount of debris is concentrated at the oil outlet, causing obstruction of oil discharge. The filter plate is inclined downwards at the end away from the connecting pipe. A bottom baffle is fixedly installed at the bottom of the inner wall of the slag collection bin. The bottom baffle is located below the filter plate and near the connecting pipe. The bottom baffle cooperates with the filter plate, and the inclination of the filter plate keeps the debris away from the connecting pipe. At the same time, the bottom baffle uses a slope at the bottom of the filter plate to block the debris. In addition, the groove at the slope position prevents metal debris that accidentally passes through the filter plate from being blocked by the bottom baffle, resulting in incomplete separation of oil and debris. The side of the bottom baffle away from the connecting pipe is a slope and has grooves evenly distributed.

[0011] Preferably, the drill bit mechanism includes a sliding platform, a first motor fixedly mounted on the outer side of the sliding platform, a lead screw rotatably mounted on the inner wall of the sliding platform, one end of the lead screw being fixedly connected to the output end of the first motor, a slide plate slidably mounted on the top of the sliding platform, the inner wall of the slide plate being threadedly connected to the outer side of the lead screw, symmetrical sliding grooves being formed on the top of the sliding platform, sliders being fixedly mounted on both sides of the bottom of the slide plate, ball bearings being provided at the bottom of the sliders, and the sliders slidingly adapting to the sliding grooves of the sliding platform through the ball bearings, a hydraulic cylinder being fixedly mounted on the top of the slide plate, a slide rail being provided on the outer side of the slide plate, and a connecting plate being slidably mounted on the slide rail of the slide plate, the top of the connecting plate being fixedly connected to the output end of the hydraulic cylinder.

[0012] Preferably, an oil tank, an oil pump, and a second motor are fixedly installed on the top of the connecting plate. The output end of the second motor passes through the connecting plate and extends to its bottom. A tool holder is fixedly installed on the output end of the second motor. A drill bit is fixedly installed on the bottom of the tool holder. An oil spray head is fixedly installed on the bottom of the connecting plate. The oil spray head is connected to the outlet of the oil pump through a pipe. The inlet of the oil pump is connected to the oil tank through a pipe.

[0013] A manufacturing process for pre-embedded channels in rail transit consists of the following steps:

[0014] S1. Hot rolling: The steel billet is heated to the plastic forming temperature and then rolled into a groove through multiple rolls. The internal structure is dense and there is no stress concentration.

[0015] S2. Cooling and straightening: The hot-rolled material is cooled and then straightened by a multi-roll precision straightener to ensure straightness.

[0016] S3. Hole machining: After cooling and straightening, the material is CNC sawed to the designed length, and then the anchor holes are machined at the designed spacing at the bottom of the groove.

[0017] S4. Anchor bolt connection: The anchoring round steel anchor bolt is fixed to the pre-drilled hole on the back of the channel by welding to form an integral anchoring structure.

[0018] During hole processing, each hole is precisely drilled, followed by reaming and rounding. After drilling, the iron filings and oil stains in the holes are cleaned. When connecting the anchor rods, a positioning clamp is used to ensure that the anchor rods are perpendicular to the channel, on the same plane, and with precise spacing. Then, spot welding is performed first, followed by continuous welding around the perimeter.

[0019] This invention provides a drilling device for manufacturing pre-embedded channels for rail transit, which has the following advantages:

[0020] (i) By using the arc-shaped protrusions on the opposite side of the convex strip to cooperate with the inclined surface on the top of the fixed plate, when the workpiece is clamped for drilling, the gap between the arc-shaped protrusions provides a gap for the output of lubricating and cooling oil. At the same time, the inclined surface on the top of the fixed plate cooperates with the support strip. Taking advantage of the fact that the arc-shaped protrusion on the top of the support strip is higher than the center position of the top of the fixed plate, when the workpiece is drilled, there is a gap between the inclined surface of the fixed plate and the bottom of the workpiece, which ensures that the drill bit can smoothly penetrate the workpiece during drilling.

[0021] (ii) By having the top arc surface of the support plate contact the bottom of the fixing plate, a supporting force is provided to the fixing plate during the drilling process. At the same time, the arc surface of the top of the support plate reduces the contact area with the bottom of the fixing plate, preventing drilling debris from entering the contact position and causing obstruction.

[0022] (III) By cooperating with the filter plate through the arc-shaped protrusions of the grid plate and the grid groove, the large debris that is blocked is moved to both sides, avoiding the blocking of the center position, and ensuring that the grid groove can smoothly filter out large debris in the oil. At the same time, the inclined filter plate keeps the filtered large debris away from the oil outlet position of the connecting pipe, avoiding a large amount of debris from accumulating at the oil outlet position and causing the oil outlet to be blocked.

[0023] (iv) By using the bottom baffle and the filter plate together, the filter plate is tilted to keep the debris away from the connecting pipe. At the same time, the bottom baffle is blocked by the inclined surface at the bottom of the filter plate, and the groove at the inclined surface prevents metal debris that accidentally passes through the filter plate from being blocked by the bottom baffle, resulting in incomplete separation of oil and debris.

[0035] Example 1, Reference Figures 1 to 5 The present invention provides this technical solution:

[0036] A drilling device for manufacturing pre-embedded channels for rail transit includes:

[0037] The frame 1 has a slag collection mechanism 2 fixedly installed on its top. The slag collection mechanism 2 has a fixing mechanism 3 installed inside it. The top of the frame 1 has a drill bit mechanism 4 fixedly installed. The outside of the frame 1 has a liquid collection tank 5 fixedly installed. The liquid collection tank 5 is connected to the slag collection mechanism 2 through a pipe.

[0038] The fixing mechanism 3 includes a fixing seat 31. A sloping groove is formed at the center of the top of the fixing seat 31. A threaded rod 33 is rotatably mounted on the inner wall of the fixing seat 31. Both ends of the threaded rod 33 penetrate the fixing seat 31 and extend to its outer side. Hexagonal heads 32 are fixedly mounted at both ends of the threaded rod 33. Fixing plates 35 are slidably mounted on both sides of the top of the fixing seat 31. The workpiece to be drilled (the pre-embedded track for rail transit) is placed on the fixing seat 31, with the bottom of the workpiece contacting the arc surface of the top of the support plate 38. The support plate 38 supports the workpiece, ensuring its stable placement. The hexagonal heads 32 are rotated by hand with a wrench, causing the threaded rod 33 to rotate within the inner wall of the fixing seat 31. The tops of the fixing plates 35 are all sloping grooves. The fixed plate 35 has a raised inclined surface at the center position, and the opposite surfaces of the fixed plate 35 are provided with grooves. Support bars 34 are fixedly installed in the grooves of the fixed plate 35. The top of the support bars 34 is provided with an arc-shaped protrusion, and the top of the arc-shaped protrusion is higher than the center position of the top inclined surface of the fixed plate 35. Since the screw hole block 37 is threadedly connected to the threaded rod 33 and the screw hole block 37 is fixed to the bottom of the fixed plate 35, when the threaded rod 33 rotates, it drives the two fixed plates 35 to slide relative to each other along the top of the fixed seat 31 until the arc protrusions 36 on the opposite surfaces of the protrusions of the fixed plate 35 are tightly attached to both sides of the workpiece. The top of the fixed plate 35 is provided with protrusions on the opposite sides of the protrusions, and arc protrusions 36 are fixedly installed on the opposite surfaces of the protrusions. The arc protrusions 36 are evenly installed on the opposite surfaces of the protrusions.

[0039] Screw holes 37 are fixedly installed on the bottom of the fixing plate 35. The inner wall of the screw holes 37 is threadedly connected to the outer side of the threaded rod 33. Support plates 38 are fixedly installed on both sides of the inner wall of the fixing seat 31. The support plates 38 are symmetrically installed along the center of the axis of the fixing seat 31, and the top of the support plate 38 is a raised arc surface. The arc surface of the top of the support plate 38 contacts the bottom of the fixing plate 35.

[0040] Example 2, based on Example 1, with reference to Figures 6 to 7The slag collection mechanism 2 includes a connecting seat 21. A collection tank 22 is fixedly installed on the top of the connecting seat 21. Guide pipes 23 are fixedly installed on both sides of the bottom of the collection tank 22. The metal slag and cooling lubricating oil mixture generated during the drilling process falls into the collection tank 22 through the inclined groove of the fixed seat 31. The mixture flows into the slag collection bin 24 through the guide pipes 23 at the bottom of the collection tank 22. It first passes through the grid plate 26. The grid grooves on the grid plate 26 filter out the larger volume of metal slag. The smaller slag and waste liquid continue to flow downward to the top of the filter plate 27. The bottom end of the guide pipes 23 is fixedly installed with the slag collection bin 24. The fixed seat 31 is fixedly installed at the center of the bottom of the inner wall of the collection tank 22. A connecting pipe 25 is fixedly installed on the outside of the slag collection bin 24.

[0041] A grating plate 26 is fixedly installed on the inner wall of the slag collection bin 24. The center of the grating plate 26 is raised in an upward arc shape, and the top of the grating plate 26 is evenly provided with grating grooves. A filter plate 27 is fixedly installed on the inner wall of the slag collection bin 24. The filter plate 27 is installed at an angle inside the slag collection bin 24, and the end of the filter plate 27 away from the connecting pipe 25 is inclined downward. The inclined filter plate 27 further filters fine waste residue. The filtered cooling waste liquid flows along the filter plate 27 to the connecting pipe 25 and is transported to the liquid collection tank 5 for recycling and reuse through the connecting pipe 25. A bottom block 28 is fixedly installed at the bottom of the inner wall of the slag collection bin 24. The bottom block 28 is located below the filter plate 27 and close to the connecting pipe 25. The side of the bottom block 28 away from the connecting pipe 25 is inclined and evenly provided with grooves.

[0042] Example 3, based on Examples 1 and 2, with reference to Figures 8 to 10The drill bit mechanism 4 includes a sliding platform 401. A first motor 405 is fixedly installed on the outer side of the sliding platform 401. A lead screw 402 is rotatably installed on the inner wall of the sliding platform 401. One end of the lead screw 402 is fixedly connected to the output end of the first motor 405. A sliding table 403 is slidably installed on the top of the sliding platform 401. The inner wall of the sliding table 403 is threadedly connected to the outer side of the lead screw 402. Sliding grooves are symmetrically opened on the top of the sliding platform 401. Slider blocks 406 are fixedly installed on both sides of the bottom of the sliding table 403. Ball bearings are provided at the bottom of the sliders 406. When the first motor 405 is started, the output end of the first motor 405 drives the lead screw 402 to rotate on the inner wall of the sliding platform 401. The sliding table 403 slides along the sliding grooves on the top of the sliding platform 401 through the sliders 406 at the bottom. Adjust the horizontal position of the slide table 403 so that the drill bit 412 is aligned with the position of the workpiece to be drilled. Start the second motor 410 and the oil pump 409. The output end of the second motor 410 drives the tool holder 413 and the drill bit 412 at the bottom to rotate at high speed. The oil pump 409 draws out the cooling lubricating oil in the oil tank 407 and delivers it to the oil spray head 411 through the pipeline. The oil spray head 411 sprays lubricating oil at the contact point between the drill bit 412 and the workpiece. The slider 406 slides and adapts to the slide groove of the slide table 401 through the ball bearings. The top of the slide table 403 is fixedly installed with a hydraulic cylinder 404. The outside of the slide table 403 is provided with a slide rail, and a connecting plate 408 is slidably installed at the slide rail of the slide table 403. The top of the connecting plate 408 is fixedly connected to the output end of the hydraulic cylinder 404.

[0043] An oil tank 407, an oil pump 409, and a second motor 410 are fixedly installed on the top of the connecting plate 408. The output end of the second motor 410 passes through the connecting plate 408 and extends to its bottom. A tool holder 413 is fixedly installed on the output end of the second motor 410. When the hydraulic cylinder 404 is activated, the output end of the hydraulic cylinder 404 pushes the connecting plate 408 to slide downward along the slide rail of the slide table 403, causing the high-speed rotating drill bit 412 to gradually approach the workpiece and perform drilling operations. The drill bit 412 is fixedly installed on the bottom of the tool holder 413. An oil spray head 411 is fixedly installed on the bottom of the connecting plate 408. The oil spray head 411 is connected to the outlet of the oil pump 409 through a pipe. The oil inlet of the oil pump 409 is connected to the oil tank 407 through a pipe.

[0044] A manufacturing process for pre-embedded channels in rail transit consists of the following steps:

[0045] S1. Hot rolling: The steel billet is heated to the plastic forming temperature and then rolled into a groove through multiple rolls. The internal structure is dense and there is no stress concentration.

[0046] S2. Cooling and straightening: The hot-rolled material is cooled and then straightened by a multi-roll precision straightener to ensure straightness.

[0047] S3. Hole machining: After cooling and straightening, the material is CNC sawed to the designed length, and then the anchor holes are machined at the designed spacing at the bottom of the groove.

[0048] S4. Anchor bolt connection: The anchoring round steel anchor bolt is fixed to the pre-drilled hole on the back of the channel by welding to form an integral anchoring structure.

[0049] During hole processing, each hole is precisely drilled, followed by reaming and rounding. After drilling, the iron filings and oil stains in the holes are cleaned. When connecting the anchor rods, a positioning clamp is used to ensure that the anchor rods are perpendicular to the channel, on the same plane, and with precise spacing. Then, spot welding is performed first, followed by continuous welding around the perimeter.

[0050] In use, the pre-embedded channel material to be machined is placed into the fixing mechanism 3 for fixing. Then, the drilling mechanism 4 is adjusted so that the drilling position of the drilling mechanism 4 corresponds to the hole machining position of the material. The tool is used to drill at the hole machining position. At the same time, cooling lubricating oil is sprayed at the drilling position. The debris generated by drilling enters the slag collection mechanism 2 under the flow of oil. The slag collection mechanism 2 filters the debris in the oil and allows the oil to enter the collection tank 5 for collection.

[0051] In the fixing mechanism 3, the workpiece of the rail transit pre-embedded channel to be drilled is placed on the fixing seat 31, and at the same time, the bottom of the workpiece is in contact with the arc surface of the top of the support plate 38. The support plate 38 supports the workpiece and ensures that the workpiece is placed stably. The hexagonal head 32 is turned by hand with a wrench, which drives the threaded rod 33 to rotate on the inner wall of the fixing seat 31. Since the threaded hole block 37 is threadedly connected to the threaded rod 33 and the threaded hole block 37 is fixed to the bottom of the fixing plate 35, when the threaded rod 33 rotates, it drives the two fixing plates 35 to slide relative to each other along the top of the fixing seat 31 until the arc protrusion 36 on the opposite side of the protrusion of the fixing plate 35 is in close contact with both sides of the workpiece.

[0052] In the drilling mechanism 4, the first motor 405 is started, and the output end of the first motor 405 drives the lead screw 402 to rotate on the inner wall of the slide table 401. The slide table 403 slides along the slide groove at the top of the slide table 401 through the bottom slider 406. The horizontal position of the slide table 403 is adjusted so that the drill bit 412 is aligned with the position of the workpiece to be drilled. The second motor 410 and the oil pump 409 are started. The output end of the second motor 410 drives the tool holder 413 and the bottom drill bit 412 to rotate at high speed. The oil pump 409 draws out the cooling lubricating oil in the oil tank 407 and delivers it to the oil spray head 411 through the pipeline. The oil spray head 411 sprays lubricating oil at the contact point between the drill bit 412 and the workpiece. Finally, the hydraulic cylinder 404 is started. The output end of the hydraulic cylinder 404 pushes the connecting plate 408 to slide down along the slide rail of the slide table 403, driving the high-speed rotating drill bit 412 to gradually approach the workpiece and perform drilling operations.

[0053] In the slag collection mechanism 2, the metal slag and cooling lubricating oil mixture generated during the drilling process falls into the collection tank 22 through the inclined groove of the fixed seat 31. The mixture flows into the slag collection bin 24 through the guide pipe 23 at the bottom of the collection tank 22. It first passes through the grid plate 26. The grid groove on the grid plate 26 filters out the larger volume of metal slag. The smaller slag and waste liquid continue to flow downward to the top of the filter plate 27. The inclined filter plate 27 further filters the fine slag. The filtered cooling waste liquid flows along the filter plate 27 to the connecting pipe 25 and is transported to the liquid collection tank 5 for recycling and reuse.
