Description

Technical Field

[0001] This invention relates to the field of integrated drilling and grinding technology, specifically to an integrated drilling and grinding equipment based on intelligent manufacturing using Internet of Things (IoT) devices. Background Technology

[0002] With social progress and technological development, metal products are increasingly widely used in industry, agriculture, and various aspects of people's lives, creating ever-increasing value for society. During the production of metal products, drilling is required, which involves drilling equipment. To facilitate the subsequent use of the drilled holes, they are then polished. To avoid repetitive positioning errors and low efficiency caused by changing equipment, integrated drilling and polishing equipment is used. However, while current integrated drilling and polishing equipment can complete both drilling and polishing operations in one machine, the polishing heads used are of complex sizes. Different specifications of polishing heads need to be changed for different hole diameters, slowing down the processing efficiency.

[0003] For example, CN221389774U discloses a drilling and grinding device. Although this application can switch between drill bits and grinding heads to complete drilling and grinding operations in a single clamping, it suffers from the problem that the grinding head needs to be changed according to the diameter of the hole being drilled, which slows down the processing efficiency. CN211867106U discloses an integrated drilling and grinding device for heat dissipation holes in switches, which also has this problem. CN211414618U discloses an inner wall grinding device for steel pipe processing. Although it can adapt to steel pipes with various hole diameters by changing the compression angle of the grinding tool, this method is usually suitable for larger holes. For smaller holes, it is difficult to complete the operation due to physical limitations.

[0004] Therefore, a drilling and grinding integrated equipment based on IoT device intelligent manufacturing is proposed. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an integrated drilling and grinding device based on intelligent manufacturing using IoT devices, thus solving the problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an integrated drilling and grinding equipment based on IoT-enabled intelligent manufacturing, comprising a worktable with bidirectional moving guide rails, a control panel mounted on the side of the worktable for controlling the processing progress, a movable platform mounted on the guide rails for support, and a laser emitter fixed on the movable platform for drilling operations. The movable platform is equipped with processing components for collaborative processing, a switching component for changing the collaborative processing position and angle, and a pre-processing component for improving processing quality. The processing components include:

[0007] An ultrasonic transmitter, located directly below the moving platform, performs flaw detection on the holes drilled in the material plate.

[0008] The grinding head, located to the side of the ultrasonic transmitter, performs different grinding processes on the hole wall based on the detection results of the ultrasonic transmitter.

[0009] The switching component includes:

[0010] The support shaft is mounted at the bottom on top of the grinding head to provide support for the grinding head;

[0011] The movable ring is movably sleeved on the outside of the support shaft via a bearing;

[0012] Electromagnet one, its sidewall is fixed to the movable ring;

[0013] A magnet is located to the side of electromagnet one, and magnetically engages with electromagnet one. Changing the position of the grinding head changes the diameter of the hole that can be ground.

[0015] Preferably, the switching assembly further includes: a fixed plate, the bottom of which is fixed to the top of the drive motor to provide support for the drive motor; a sliding plate, the bottom of which is fixed to the top of the fixed plate; and an adjusting push rod, one end of which is fixed to the side wall of the sliding plate to provide power for changing the position of the grinding head.

[0016] Preferably, the switching assembly further includes: a moving motor, fixed to the side wall of the moving table via a motor housing; a threaded rod, one end of which is fixed to the output end of the moving motor; a sliding rod, threadedly connected to the threaded rod, which changes the position of the grinding head under the drive of the moving motor; and a cover, fixed to the bottom of the sliding rod.

[0017] Preferably, the switching assembly further includes: a steering motor, which is fixed to the top of the inner wall of the housing; a first gear, which is fixed to the output end of the steering motor via a motor shaft; a second gear, which meshes with the first gear; and a rotating shaft, one end of which is fixedly inserted inside the second gear, and the other end of which moves through the housing to the bottom.

[0018] Preferably, the switching assembly further includes a support plate, the top of which is fixed to the other end of the rotating shaft, and the angle of collaborative processing is changed under the drive of the steering motor.

[0019] Preferably, the pretreatment assembly includes: an upper guide plate, the bottom of which is fixed to the top of the limiting plate; a sliding block, one end of which is slidably inserted inside the upper guide plate and can move linearly up and down along the upper guide plate under the action of external force; and a spring, one end of which is fixed to the top of the sliding block and the other end of which is fixed to the top of the inner wall of the upper guide plate, providing an upward elastic force to the sliding block.

[0020] Preferably, the pretreatment assembly further includes: a movable electromagnet, the sidewall of which is fixed to the sliding block; and a fixed electromagnet assembly, which is fixed to the sidewall of the upper guide plate and magnetically engages with the movable electromagnet to change the position of the movable electromagnet.

[0021] Preferably, the pretreatment assembly further includes: a lower guide plate, the top of which is fixed to the bottom of the limiting plate; a counterweight block, one end of which is slidably inserted into the lower guide plate; and a grinding belt, one end of which is fixed to the top of the counterweight block and the other end of which is fixed to the bottom of the sliding block, which performs pretreatment friction on the hole wall after the movable electromagnet moves downward and rotates with the counterweight block.

[0022] This invention provides an integrated drilling and grinding device based on intelligent manufacturing using IoT devices. Compared with existing technologies, it has the following advantages:

[0023] (1) The integrated drilling and grinding equipment based on IoT device intelligent manufacturing achieves "single clamping and continuous operation". The entire process from drilling to grinding is completed in the same coordinate system, with highly coordinated operation, which completely avoids the cumulative error caused by repeated positioning, and ensures the high consistency between the hole position and the grinding area. All processing steps are based on the same initial positioning reference, which improves the geometric relationship accuracy between multiple processes. It is especially suitable for precision parts with strict requirements for hole spacing and position. It eliminates non-processing time such as workpiece handling, clamping, and tool setting between different equipment, significantly shortens the single-piece processing cycle, and enables real-time detection and feedback control to dynamically formulate grinding strategies, realize personalized processing of "one hole, one strategy", improve quality stability, and adapt to the processing requirements of variable spacing hole array.

[0024] (2) The integrated drilling and grinding equipment based on IoT device intelligent manufacturing can adapt the same grinding head to holes of different diameters by controlling the offset (eccentricity) of the grinding head relative to the spindle center. It can complete deburring or surface finishing of multiple hole diameters without frequent grinding head replacement, significantly improving the equipment flexibility and changeover efficiency. At the same time, it eliminates the need to prepare multiple types of grinding heads, reducing inventory. Furthermore, it can be combined with path planning algorithms, and the eccentric motion can simulate "drawing a circle" or "cycloidal trajectory" to achieve uniform grinding of non-standard holes such as elliptical holes and waist-shaped holes. In addition, the rotation of the grinding head can allow each point on the circumference of the grinding head to participate in cutting in turn, avoiding premature wear in some areas.

[0025] (3) This integrated drilling and grinding equipment based on IoT device intelligent manufacturing adopts flexible friction tools (such as magnetic abrasive particles, elastic abrasive flow, flexible brush wheel, ultrasonic vibration friction head, etc.) to gently peel off the loosely attached recast layer and oxides through a low-stress, high-coverage contact method, avoiding new mechanical damage to the substrate, initially releasing some residual stress on the surface. The flexible friction process has low heat and fast heat dissipation, and can remove the oxide layer with poor thermal conductivity in advance, so that the substrate is exposed to a good heat dissipation state, making the heat conduction efficiency higher and the heat accumulation less during subsequent grinding, resulting in better grinding effect. It can construct a multi-level pre-treatment + grinding strategy based on defect level to achieve "on-demand processing", avoid over-processing, save energy and be efficient, and truly move towards adaptive intelligent manufacturing.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] The devices or elements referred to in the embodiments of this application or implied herein must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the embodiments of this application. In the description of the embodiments of this application, "a plurality of" means two or more, unless otherwise precisely specified.

[0045] Please see Figures 1 to 15 The present invention provides the following technical solutions:

[0046] Example 1: A drilling and grinding integrated equipment based on IoT device intelligent manufacturing, including a worktable 1 with bidirectional X and Z axis moving guide rails, wherein the X axis is... Figure 1 The direction in which the central moving platform 12 moves toward the side where the control panel 11 is located, with the Z-axis as... Figure 1The moving stage 12 moves in the direction of the laser emitter 13. The bottom of the control panel 11 is fixedly mounted on the side of the worktable 1 for controlling the processing progress. The moving stage 12 is movably mounted on the X-axis guide rail. The laser emitter 13 is fixedly mounted on the moving stage 12 for drilling operations. The moving stage 12 is equipped with processing components for collaborative processing and switching components for changing the collaborative processing position and angle. The processing components include:

[0047] The ultrasonic transmitter 29 is located directly below the moving stage 12, with its top fixed to the bottom of the cover 23, and performs flaw detection on the holes drilled in the material plate body 101.

[0048] The grinding head 210 is located to the side of the ultrasonic transmitter 29 and performs different grinding processes on the hole wall according to the detection results of the ultrasonic transmitter 29.

[0049] The switching component includes;

[0050] The movable motor 2 is fixedly mounted on the side wall of the movable table 12 via a motor housing. One end of the threaded rod 21 is fixedly mounted on the output end of the movable motor 2 via a coupling. The other end of the threaded rod 21 is movably inserted into the movable table 12. The sliding rod 22 is threadedly connected to the threaded rod 21. The sliding rod 22 can change the position of the grinding head 210 under the drive of the movable motor 2. One end of the sliding rod 22 is slidably inserted into the movable table 12. The top of the cover 23 is fixedly mounted on the bottom of the sliding rod 22. The top of the steering motor 24 is fixedly mounted on the top of the inner wall of the cover 23. Gear 1 25 is fixedly mounted on the output end of the steering motor 24 via a motor shaft. Gear 22 26 is meshed with gear 1 25. The steering motor 24, gear 1 25, and gear 2 26 are all located inside the cover 23. One end of the rotating shaft 27 is fixedly inserted into gear 26 and movably mounted inside the cover 23 via a bearing. The other end of the rotating shaft 27 movably passes through the cover 23 to the bottom, and the other end of the rotating shaft 27 is fixedly mounted on the top of the grinding head 210.

[0051] In use, the material plate 101 to be drilled is placed on top of the workbench 1 and fixed. Then, the moving stage 12 is controlled by the control panel 11 to move on the workbench 1, so that the moving stage 12 drives the laser emitter 13 to move to the position to be drilled according to the design drawings, and drills the material plate 101. After completing the drilling of the first hole in the row, the moving stage 12 is controlled by the control panel 11 to continue to move forward a distance, so that the laser emitter 13 is in the position to be drilled, and the drilling of the next hole continues. At the same time, the ultrasonic emitter 29 is directly above the drilled hole. The ultrasonic emitter 29 is activated to emit ultrasonic waves to detect the hole wall, thereby determining whether there are cracks, defects, direction, length and depth of the drilled hole wall.

[0052] The grinding scheme is determined based on the detection results of the ultrasonic transmitter 29. If there are no cracks or defects, the grinding head 210 is driven to rotate by the drive element through the control panel 11, thereby grinding the drilled hole.

[0053] If cracks or defects exist, and the cracks are deep or have strong penetration, which may have affected the structural strength, then scrapping or rework should be considered.

[0054] If cracks or defects exist, but are shallow microcracks and do not show a tendency to expand, then light polishing should be performed.

[0055] After obtaining the detection results from the ultrasonic transmitter 29, if grinding is required, the control panel 11 is used to start the moving motor 2. The moving motor 2 drives the threaded rod 21 to rotate. The threaded rod 21 and the sliding rod 22 are threadedly engaged, while the sliding rod 22 and the moving table 12 are slidably engaged. This allows the sliding rod 22 to move linearly along the moving table 12 under the drive of the threaded rod 21. The sliding rod 22 drives the cover 23 to move, which in turn drives the rotating shaft 27 to move. The rotating shaft 27 then drives the support plate 28 to move, which in turn drives the drive element and the grinding head 210 to move. This allows the grinding head 210 to move to the position of the first hole to be drilled. At this point, the control panel 11 is used to control the drive element to drive the grinding head 210 to rotate.

[0056] In this scheme, another implementation method is: the grinding head 210 can also be directly mounted on the rotating shaft 27, and the steering motor 24 drives the gear 1 25 to rotate. The gear 1 25 meshes with the gear 26, thereby driving the gear 26 to rotate synchronously. The gear 26 drives the rotating shaft 27 to rotate, and the rotating shaft 27 drives the grinding head 210 to rotate, thereby performing grinding.

[0057] Furthermore, the sliding rod 22 can be configured to be extendable up and down to adapt to the vertical distance between the grinding head 210 and the wall of the hole to be ground.

[0058] Example 2, the technical solution of which differs from Example 1 is as follows: instead of directly mounting the grinding head 210 on the rotating shaft 27, a sliding plate 31 is slidably mounted in the support plate 28, a fixing plate 32 is mounted on the bottom of the sliding plate 31, a drive motor 33 is mounted on the bottom of the fixing plate 32, and a mounting block 34 is fixedly mounted on the drive shaft of the drive motor 33. The grinding head 210 is mounted on the splicing block 301 through the support shaft 39, and spliced ​​together with the mounting block 34 by means of the splicing block 301.

[0059] The switching component also includes:

[0060] The top of the support plate 28 is fixedly connected to the other end of the rotating shaft 27. The support plate 28 can change the angle of collaborative processing under the drive of the steering motor 24. One end of the adjusting push rod 3 is fixedly installed on the side wall of the sliding plate 31. The adjusting push rod 3 is used to provide power for changing the position of the grinding head 210. The bottom of the sliding plate 31 is fixedly installed on the top of the fixed plate 32. The bottom of the fixed plate 32 is fixedly installed on the top of the drive motor 33. The fixed plate 32 provides support for the drive motor 33. The drive motor 33 is fixedly installed on the top of the mounting block 34 through the drive shaft. The drive motor 33 can provide power for the rotation of the grinding head 210.

[0061] The bottom of the mounting block 34 is fixedly mounted on the top of the limiting plate 35. The bottom of the limiting plate 35 is fixedly connected to the top of the magnet 36. The limiting plate 35 provides support for the magnet 36. The magnet 36 is located to the side of the electromagnet 37. The magnet 36 and the electromagnet 37 are magnetically engaged. The diameter of the hole that can be ground can be changed by changing the position of the grinding head 210. The side wall of the electromagnet 37 is fixedly mounted on the movable ring 38. The inner ring of the movable ring 38 is movably sleeved on the outside of the support shaft 39 through the bearing. The bottom of the support shaft 39 is fixedly mounted on the top of the grinding head 210. The support shaft 39 can provide support for the grinding head 210. One end of the support shaft 39 slides through the limiting plate 35. The bottom of the splicing block 301 is fixedly mounted on the top of the support shaft 39. One end of the splicing block 301 slides into the mounting block 34.

[0062] When in use, when the grinding head 210 needs to be rotated, the drive motor 33 is started directly through the control panel 11. The drive motor 33 drives the drive shaft to rotate, the drive shaft drives the mounting block 34 to rotate, the mounting block 34 drives the support shaft 39 to rotate through the splicing block 301, and the support shaft 39 drives the grinding head 210 to rotate, thereby performing the grinding operation.

[0063] Furthermore, an adjusting push rod 3 is installed on the side wall of the sliding plate 31. When the previous hole and the next hole are not perpendicular or parallel, the position of the sliding plate 31 is changed by adjusting the push rod 3. Then, the steering motor 24 drives the gear 1 25 to rotate, the gear 1 25 drives the gear 26 to rotate, the gear 26 drives the rotating shaft 27 to rotate, the rotating shaft 27 drives the support plate 28 to rotate, and the support plate 28 drives the eccentric sliding plate 31, the fixed plate 32, the drive motor 33 and the grinding head 210 to rotate, so that the grinding head 210 deflects to the required angle with the rotating shaft 27 as the axis. Then, the drive motor 33 drives the grinding head 210 to rotate, thereby performing grinding operations on the hole wall.

[0064] Furthermore, to address the grinding requirements of different hole diameters, a limiting plate 35 provides support to the magnet 36. When the electromagnet 37 is energized, its magnetic properties match those of the magnet 36. When the hole diameter to be ground is larger than the diameter of the grinding head 210, the control panel 11 controls the energization of the electromagnet 37 to attract the magnet 36, causing the electromagnet 37 to move towards the side where the magnet 36 is located. The electromagnet 37 drives the movable ring 38 to move, which in turn drives the support shaft 39 to move. The support shaft 39 then drives the splicing block 301 to move. The limiting plate 35 and the splicing block 301... The sliding fit between the splicing block 301 and the support shaft 39 allows the splicing block 301 to move only in a straight line along the limit plate 35. The splicing block 301 and the support shaft 39 drive the grinding head 210 to move, causing the grinding head 210 to shift away from the drive shaft. The splicing block 301 slides out of the mounting block 34. At this time, the drive motor 33 is started again, which drives the limit plate 35 to rotate through the drive shaft. The limit plate 35 drives the splicing block 301 to rotate, and the splicing block 301 drives the support shaft 39 and the grinding head 210 to rotate, thereby grinding the hole wall. By controlling the magnetic strength of the electromagnet 37 after it is energized, the grinding requirements of different hole diameters can be adapted.

[0065] Since the limiting plate 35 and the splicing block 301 can rotate synchronously with the drive shaft and the mounting block 34, when it is necessary to grind the hole wall that matches the diameter of the hole head 210, it is only necessary to set the magnetism of the electromagnet 37 after it is energized to repel the magnet 36, so that the splicing block 301 can be inserted into the mounting block 34 again. At this time, the drive motor 33 will drive the grinding head 210 to rotate around the support shaft 39 through the drive shaft, the mounting block 34, the limiting plate 35, the splicing block 301, and the support shaft 39.

[0066] During the rotation of the grinding head 210 around the drive shaft and support shaft 39, when the splicing block 301 rotates to the side facing the magnet 36, the splicing block 301 moves into the mounting block 34 between the repulsive forces of the two. When the splicing block 301 rotates to the side away from the magnet 36, the splicing block 301 abuts against the inner wall of the limiting plate 35, thereby preventing the splicing block 301 from separating from the mounting block 34.

[0067] In another embodiment, which differs from the aforementioned embodiment, in order to make the connection between the mounting block 34 and the splicing block 301 tighter, a fixed magnet can be installed on each of the two sides that are close to each other, so that when the two are spliced ​​together, the two fixed magnets can attract each other, further increasing the tightness of the connection.

[0068] In another embodiment, different from the aforementioned embodiment, the electromagnet 37 is configured as a ring, which is sleeved around the movable ring 38. At the same time, the support shaft 39 and the splicing block 301 are configured to be movably connected by a bearing. This allows the grinding head 210 to rotate not only around the drive shaft but also around the support shaft 39 when it contacts the hole wall. This makes the wear of the grinding head 210 more uniform during grinding. Meanwhile, the ring-shaped electromagnet 37 can maintain its position by generating an attractive force with the magnet 36, regardless of the angle to which the grinding head 210 and the support shaft 39 rotate around the support shaft 39.

[0069] The effect is particularly outstanding when applied to drilling and grinding operations on the following products:

[0070] For the operation of film cooling holes on aero-engine blades, which require various small-diameter, oblique, and densely arranged holes, the hole type can be quickly switched without changing the head, thus reducing the risk of thermal damage.

[0071] For mold cooling channels, which are used in deburring operations with large diameter-to-diameter ratio holes, the self-rotation mechanism prevents uneven wear and extends the life of slender grinding needles.

[0072] The technical solution of this embodiment that differs from the previous embodiments includes: a pre-processing component for improving processing quality is provided on the moving stage 12, the pre-processing component including:

[0073] The bottom of the upper guide plate 4 is fixedly installed on the top of the limiting plate 35. One end of the sliding block 41 is slidably inserted into the upper guide plate 4. The sliding block 41 can move vertically up and down along the upper guide plate 4 under the action of external force. One end of the spring 42 is fixedly installed on the top of the sliding block 41, and the other end of the spring 42 is fixedly installed on the top of the inner wall of the upper guide plate 4. The spring 42 can provide an upward elastic force to the sliding block 41. The side wall of the movable electromagnet 43 is fixedly installed on the sliding block 41. One end of the fixed electromagnet assembly 44 is fixed on the side wall of the upper guide plate 4. The fixed electromagnet assembly 44 and the movable electromagnet 43 are magnetically coupled, thereby changing the position of the movable electromagnet 43. The fixed electromagnet assembly 44 includes two electromagnets, which are located on the upper and lower sides of the movable electromagnet 43 respectively.

[0074] The top of the lower guide plate 45 is fixedly installed at the bottom of the limiting plate 35. One end of the counterweight 46 is slidably inserted inside the lower guide plate 45. One end of the grinding belt 47 is fixedly installed at the top of the counterweight 46, and the other end of the grinding belt 47 is fixedly installed at the bottom of the sliding block 41. The grinding belt 47 can perform pre-treatment friction on the hole wall after the movable electromagnet 43 moves downward and rotates with the counterweight 46.

[0075] In use, after ultrasonic testing of the material plate 101 with completed drilling is completed, the fixed electromagnet group 44 is energized through the control panel 11. After energization, the upper fixed electromagnet group 44 and the movable electromagnet 43 are magnetically repelled, and the lower fixed electromagnet group 44 and the movable electromagnet 43 are magnetically attracted. This causes the movable electromagnet 43 to move downward against the upward pulling force provided by the spring 42. The movable electromagnet 43 drives the sliding block 41 to move synchronously. The sliding block 41 slides with the upper guide plate 4, so that the sliding block 41 can only move in a straight line along the upper guide plate 4.

[0076] The sliding block 41 drives the grinding belt 47 to move downwards synchronously, so that the grinding belt 47 can no longer provide upward pulling force to the counterweight 46. Under the action of gravity, the counterweight 46 slides obliquely downwards along the lower guide plate 45, thus passing through the hole punched on the material plate body 101. At this time, the control panel 11 controls the steering motor 24 to rotate, which will drive the limit plate 35 to rotate around the rotation shaft 27. At this time, the counterweight 46 also flies away from the axis where the grinding head 210 is located under the action of centrifugal force, thus enabling the grinding belt 47 to contact the hole wall. At the same time, the grinding belt 47 also rotates around the rotation shaft 27, thus pre-treating the recast layer or oxide remaining on the hole wall. After the pre-treatment is completed, the magnetism of the electromagnet in the fixed electromagnet group 44 is reversed, so that the movable electromagnet 43 can drive the sliding block 41, grinding belt 47, and counterweight 46 to return upwards under the combined action of magnetic force and spring 42. Figure 8 The initial position is shown, and then the grinding head 210 is controlled by the control panel 11 to perform the grinding operation.

[0079] Parallelism: The parallelism defined in this application is not limited to absolute parallelism. This definition of parallelism can be understood as basic parallelism. It allows for situations where the parallelism is not absolute due to factors such as assembly tolerance, design tolerance, and structural flatness. It also allows for errors within a small angular range, such as within 10 degrees of assembly error. These can all be considered as parallel relationships.

[0080] Perpendicularity: The perpendicularity defined in this application is not limited to an absolute perpendicular intersection (with an included angle of 90 degrees). It is permissible for non-absolute perpendicular intersections caused by factors such as assembly tolerances, design tolerances, and structural flatness. It is permissible for errors within a small angular range, such as an assembly error range of 80 to 100 degrees, which can all be understood as a perpendicular relationship.

[0081] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
