Description

Technical Field

[0001] This invention relates to the field of drilling and tapping devices, specifically a drilling and tapping device for the end of a robot rotor shaft. Background Technology

[0002] Drilling and tapping equipment is a type of device used for processing metallic and non-metallic materials. It is mainly used to drill holes and tap threads on workpieces. Its structural design typically includes a fixture, a drill bit, and a tapping tool to ensure precise processing on different materials. By adjusting the rotation speed and feed rate, operators can optimize processing parameters according to the material characteristics. It is widely used in manufacturing, machining, and maintenance fields and is suitable for both large-scale production and small-batch customization.

[0003] Chinese patent CN204195239U discloses a rotor shaft end drilling and tapping device, comprising a three-jaw chuck and a machine tool post fixedly mounted on a machine tool. The three-jaw chuck clamps one end of the rotor shaft, and a support frame is provided below the other end of the rotor shaft. The machine tool post is located on one side of the other end of the rotor shaft. A fixture is fixedly installed on the end of the machine tool post facing the rotor shaft. A drill bit and a turning tap are installed on the end of the fixture facing the rotor shaft. The drill bit and the turning tap are distributed at the upper and lower ends of the fixture. The turning tap is clamped to the end of the fixture by a clamping bolt. This device can combine the two processes of drilling and tapping the motor rotor shaft end into one process, processing drilling and tapping at the same time. The processing is easy and simple, with good concentricity, improving processing quality and reducing labor productivity.

[0004] However, current drilling and tapping devices have the following problems: when drilling and tapping a long rotor shaft end, the distance between the drilling and tapping end and the fixed part of the fixed component is relatively far. Therefore, the rotor shaft end far from the fixed component will wobble slightly during drilling and tapping, which will cause problems such as hole eccentricity, thread misalignment, and deterioration of hole shape / roughness. Therefore, we propose a drilling and tapping device for the rotor shaft end of a robot. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a drilling and tapping device for the rotor shaft end of a robot, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a drilling and tapping device for a robot rotor shaft end, comprising a worktable, two electric push rods fixed to the top of the worktable, and an L-shaped block fixed to the telescopic end of each of the two electric push rods. One L-shaped block has a drilling component on its side for drilling the rotor shaft end, and the other L-shaped block has a tapping component on its side for tapping the rotor shaft end. A linear motor is mounted on the top of the worktable, and a fixing component for fixing the rotor shaft end is mounted on the inner wall of the moving end of the linear motor. Anti-vibration devices are provided on the sides of the electric push rods. The device includes two L-shaped plates, the sides of which are respectively fixed to the sides of two electric push rods. Support blocks are fixed to the sides of both L-shaped plates. Two symmetrical pressing plates are slidably installed on the inner walls of the two support blocks. Springs are installed on the outer sides of the two pressing plates, which are furthest from each other, and on the inner walls of the support blocks. Hollow blocks are fixed to the outer sides of the two pressing plates. Guide blocks are fixed to the sides of the hollow blocks. Fixing blocks are fixed to the top and bottom of the L-shaped blocks. Long columns are fixed to the sides of the fixing blocks, and the guide blocks are located on the displacement trajectory of the long columns.

[0007] According to the above technical solution, two moving plates are fixed on the top of both sides of the moving end of the linear motor, and a fixing frame is fixed on the side of the moving plate. An elastic plate is fixed on the top and bottom of the inner wall of the fixing frame, and the elastic plate is in contact with the pressing plate.

[0008] According to the above technical solution, an anti-residue device is provided on the side of the fixed end of the electric push rod. The anti-residue device includes a fixed bracket, which is fixed to the side of the fixed end of the electric push rod. An electric push rod is fixed to the inner wall of the fixed bracket. A U-shaped plate is fixed to the telescopic end of the electric push rod. A cleaning roller is rotatably installed on the inner wall of the U-shaped plate.

[0009] According to the above technical solution, a rotating rod is fixedly installed on the top of the cleaning roller, a friction wheel is fixed on the top of the rotating rod, an L-shaped block is fixed on the top of the U-shaped plate, a track block is fixed on the side of the L-shaped block, a track plate is fixed on the top of the fixing frame, a slider is slidably installed on the inner wall of the track plate, a friction block is fixed on the top of the slider, and an L-shaped sliding plate is fixed on the side of the slider.

[0010] According to the above technical solution, the side of the L-shaped slide plate is slidably mounted on the inner wall of the track block, the outer wall of the friction wheel is roughened, the side of the friction block is roughened, and the roughened surface of the friction wheel is in contact with the roughened surface of the friction block.

[0011] According to the above technical solution, the side of the L-shaped plate is provided with an anti-deviation device, which includes two sawtooth positioning blocks 1, which are respectively fixed on the side of the two L-shaped plates. Sawtooth positioning blocks 2 are fixed on both sides of the moving end of the linear motor. A vertical plate is fixed on the top of the two L-shaped plates. A fixing rod is fixed between the two vertical plates. The two moving plates are slidably installed on the outer wall of the fixing rod. A spring 1 is provided between the moving plate and the vertical plate.

[0012] According to the above technical solution, a sponge pad one is fixed to the side of the vertical plate, and a sponge pad two is fixed to the side of the movable plate.

[0013] According to the above technical solution, the first sawtooth positioning block is located on the displacement trajectory of the second sawtooth positioning block, and the first sponge pad is located on the displacement trajectory of the second sponge pad.

[0014] This invention provides a drilling and tapping device for the end of a robot rotor shaft. It has the following advantages: (1) Through the setting of the anti-vibration device, the L-shaped plate, the moving plate, the support block, the pressing plate, the spring, the hollow block, the guide block, the fixing block, and the long column are used to press the outer wall of the long rotor shaft end where drilling and tapping are required. This avoids the problem of slight shaking during drilling and tapping caused by the long rotor shaft end being far from the fixed part of the fixing component, which would cause hole eccentricity, thread misalignment, and deterioration of hole shape / roughness. At the same time, with the cooperation of the fixing frame, the elastic plate, and the pressing plate, the movement of the fixing frame will drive the elastic plate along the pressing plate. The surface of the plate is moved to avoid iron filings and wires remaining on the surface of the pressing plate after drilling and tapping. This would prevent the pressing plate from pressing the iron filings and wires onto the rotor shaft end surface the next time it is used, causing wear on the rotor shaft end surface. At the same time, with the cooperation of the elastic plate, the pressing plate, and the hollow block, the elastic plate will recover under its own elastic force, and the second spring will drive the pressing plate and the hollow block to reset under its own elastic force, thus realizing the shaking of the pressing plate. The shaking of the pressing plate improves the effect of iron filings and wires falling off the surface of the pressing plate.

[0015] (2) By setting up an anti-residue device, the present invention, with the cooperation of a fixed bracket, an electric push rod II, a U-shaped plate, and a cleaning roller, will clean off the iron filings remaining on the surface of the rotor shaft end hole, thereby avoiding the problem that the tapping part will bring the residual iron filings into the rotor shaft end hole during tapping, resulting in unqualified threads, tooth damage, and thread deviation. At the same time, with the cooperation of the cleaning roller, rotating rod, friction wheel, L-shaped block, track block, track plate, slider, friction block, and L-shaped sliding plate, the rotation of the friction wheel will drive the rotating rod to rotate, and the rotation of the rotating rod will drive the cleaning roller to rotate, thereby avoiding the problem that the cleaning roller will clean the iron filings in the same place for a long time, resulting in a reduction in the subsequent cleaning effect.

[0016] (3) By setting up an anti-deviation device, the rotor shaft end that has been drilled is tapped with the cooperation of sawtooth positioning block one and sawtooth positioning block two. This avoids the problem that when tapping the rotor shaft end after drilling is completed, the rotor shaft end will be slightly deviated due to the inability to accurately position the rotor shaft end, which would cause the rotor shaft end to be scrapped. At the same time, with the cooperation of vertical plate, fixing rod, spring one, sponge pad one and sponge pad two, the impact force of sawtooth positioning block two on sawtooth positioning block one can be reduced, thereby avoiding the problem that sawtooth positioning block two and sawtooth positioning block one will wear out during long-term use, resulting in inaccurate positioning.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Please see Figures 1-8One embodiment of the present invention is as follows: a drilling and tapping device for a robot rotor shaft end, comprising a worktable 1, two electric push rods 21 fixed on the top of the worktable 1, and L-shaped blocks 22 fixed to the telescopic ends of the two electric push rods 21. One L-shaped block 22 has a drilling component 23 for drilling the rotor shaft end on its side (the drilling component 23 is prior art and will not be described in detail). The other L-shaped block 22 has a tapping component 24 for tapping the rotor shaft end on its side (the tapping component 24 is prior art and will not be described in detail). A linear motor 3 is mounted on the top of the worktable 1, and a fixing assembly 4 for fixing the rotor shaft end is mounted on the inner wall of the moving end of the linear motor 3 (the fixing assembly 4 is prior art and will not be described in detail). An anti-vibration device 6 is mounted on the side of the electric push rods 21, and the anti-vibration device 6 includes two L-shaped plates 601, the sides of which are respectively fixed to the two electric push rods 21. On the side of 21, support blocks 61 are fixed to the sides of the two L-shaped plates 601. Two symmetrical pressing plates 62 are slidably installed on the inner walls of the two support blocks 61. Springs 63 are provided on the inner walls of the support blocks 61 on the side of the two pressing plates 62 that are far apart from each other. Hollow blocks 64 are fixed to the side of the two pressing plates 62 that are far apart from each other. Guide blocks 65 are fixed to the side of the hollow blocks 64. Fixing blocks 66 are fixed to the top and bottom of the L-shaped block 22. Long columns 67 are fixed to the side of the fixing blocks 66. Guide blocks 65 are located on the displacement trajectory of long columns 67. With the above structure, the pressing plates 62 will press down on the outer wall of the longer rotor shaft end where drilling and tapping are required, thereby avoiding the problem of slight shaking during drilling and tapping due to the distance between the drilling and tapping end and the fixing point of the fixing component 4, which would cause hole eccentricity, thread misalignment, and deterioration of hole shape / roughness.

[0021] Two movable plates 602 are fixed to the top of both sides of the moving end of the linear motor 3. A fixing frame 68 is fixed to the side of the movable plate 602. An elastic plate 69 is fixed to the top and bottom of the inner wall of the fixing frame 68. The elastic plate 69 is in contact with the pressing plate 62. With the above structure, the movement of the fixing frame 68 will drive the elastic plate 69 to move along the surface of the pressing plate 62, thereby avoiding the iron filings and wires generated after drilling and tapping from remaining on the surface of the pressing plate 62. This would prevent the pressing plate 62 from pressing the iron filings and wires onto the rotor shaft end surface the next time it is used, causing wear on the rotor shaft end surface. At the same time, the elastic plate 69 will recover under its own elastic force, and the spring 63 will drive the pressing plate 62 and the hollow block 64 to reset under its own elastic force, thereby realizing the shaking of the pressing plate 62. The shaking of the pressing plate 62 improves the effect of iron filings and wires falling off the surface of the pressing plate 62.

[0022] An anti-residue device 7 is provided on the side of the fixed end of the electric push rod 21. The anti-residue device 7 includes a fixed bracket 71, which is fixed to the side of the fixed end of the electric push rod 21. An electric push rod 72 is fixed to the inner wall of the fixed bracket 71. A U-shaped plate 73 is fixed to the telescopic end of the electric push rod 72. A cleaning roller 74 is rotatably installed on the inner wall of the U-shaped plate 73. With the above structure, the cleaning roller 74 will clean off the iron filings remaining on the surface of the rotor shaft end hole, thereby preventing the tapping part 24 from bringing residual iron filings into the rotor shaft end hole during tapping, which would lead to problems such as unqualified tapped threads, tooth profile damage, and thread deviation.

[0023] A rotating rod 75 is fixedly installed on the top of the cleaning roller 74, and a friction wheel 76 is fixed on the top of the rotating rod 75. An L-shaped block 77 is fixed on the top of the U-shaped plate 73, and a track block 78 is fixed on the side of the L-shaped block 77. A track plate 79 is fixed on the top of the fixing frame 68, and a slider 710 is slidably installed on the inner wall of the track plate 79. A friction block 711 is fixed on the top of the slider 710, and an L-shaped sliding plate 712 is fixed on the side of the slider 710. The side of the L-shaped sliding plate 712 is slidably installed on the inner wall of the track block 78. The outer wall of the friction wheel 76 is rough, and the side of the friction block 711 is rough. The rough surface of the friction wheel 76 is in contact with the rough surface of the friction block 711. With the above structure, the rotation of the friction wheel 76 will drive the rotating rod 75 to rotate, and the rotation of the rotating rod 75 will drive the cleaning roller 74 to rotate. This avoids the problem that the cleaning roller 74 will use the same place to clean iron filings for a long time, which will reduce the subsequent cleaning effect.

[0024] In use, the rotor shaft end is clamped by the fixing component 4. Then, the linear motor 3 is started. The moving end of the linear motor 3 moves the rotor shaft end to the front end of the drilling component 23 via the fixing component 4. Then, the electric push rod 21 corresponding to the drilling component 23 is started. The telescopic end of the electric push rod 21 moves the drilling component 23 to drill the rotor shaft end via the L-shaped block 22. After drilling is completed, the linear motor 3 is started again. The moving end of the linear motor 3 moves the drilled rotor shaft end to the front end of the tapping component 24. Then, the electric push rod 21 corresponding to the tapping component 24 is started. The telescopic end of the electric push rod 21 moves the tapping component 24 to tap the rotor shaft end via the L-shaped block 22. Finally, After the tapped rotor shaft end is removed from the fixing assembly 4, when drilling and tapping the longer rotor shaft end, the movement of the L-shaped block 22 will cause the fixing block 66 to move. The movement of the fixing block 66 will cause the long column 67 to move. When the long column 67 moves, it will abut against the guide block 65 and move along the surface of the guide block 65. At this time, after the guide block 65 is subjected to the abutment force of the long column 67, it will drive the hollow block 64 and the pressing plate 62 to move towards the rotor shaft end. The movement of the pressing plate 62 will stretch the corresponding spring 63. When the long column 67 moves into the hollow block 64, the pressing plate 62 will press down on the outer part of the longer rotor shaft end that needs to be drilled and tapped. The wall is designed to prevent slight wobbling during drilling and tapping of the longer rotor shaft end due to the greater distance between the drilled and tapped end and the fixing point of the fixing component 4, which could cause problems such as hole misalignment, thread misalignment, and deterioration of hole shape / roughness. The moving end of the linear motor 3 drives the moving plate 602 to move, which in turn drives the fixing frame 68 to move. The movement of the fixing frame 68 drives the elastic plate 69 to move along the surface of the pressing plate 62. This prevents iron filings and wires from remaining on the surface of the pressing plate 62 after drilling and tapping, which would cause the pressing plate 62 to press the iron filings and wires onto the rotor shaft end surface the next time it is used. This causes wear on the rotor shaft end surface. When the elastic plate 69 moves to the hollow block 64, the elastic plate 69 will deform under the force of the hollow block 64. At the same time as the elastic plate 69 deforms, the hollow block 64 will move away from the elastic plate 69. The movement of the hollow block 64 will cause the pressing plate 62 to stretch the second spring 63. When the elastic plate 69 leaves the hollow block 64, the elastic plate 69 will recover under its own elastic force, and the second spring 63 will drive the pressing plate 62 and the hollow block 64 to reset under its own elastic force, thereby realizing the shaking of the pressing plate 62. The shaking of the pressing plate 62 improves the effect of iron filings and iron wires falling off the surface of the pressing plate 62.

[0025] After the rotor shaft end drilling is completed, when the moving end of the linear motor 3 moves the rotor shaft end towards the tapping part 24 via the fixing component 4, the electric push rod 72 is activated. The telescopic end of the electric push rod 72 will move the U-shaped plate 73. The movement of the U-shaped plate 73 will move the cleaning roller 74 to the path in front of one end of the rotor shaft end drilling. When one end of the rotor shaft end drilling passes the cleaning roller 74, the cleaning roller 74 will clean off the iron filings remaining on the surface of the rotor shaft end hole, thereby preventing the tapping part 24 from bringing residual iron filings into the rotor shaft end hole during tapping, which would cause problems such as unqualified threads, tooth profile damage, and thread misalignment. The movement of the fixing bracket 68 will move the track. The track plate 79 moves, which in turn moves the slider 710. The slider 710 moves the L-shaped slide plate 712 along the inner wall of the track block 78. The slider 710 moves the friction block 711. When the rough surface of the friction block 711 contacts the rough surface of the friction wheel 76, the friction wheel 76 rotates due to the friction between the rough surfaces of the friction block 711 and the friction wheel 76. The rotation of the friction wheel 76 drives the rotating rod 75 to rotate, which in turn drives the cleaning roller 74 to rotate. This avoids the cleaning roller 74 from cleaning iron filings in the same place for a long time, which would reduce the subsequent cleaning effect.

[0026] It should be noted that the friction block 711 and friction wheel 76 are driving structures and can be replaced synchronously by driving structures such as racks and pinions, and are not required to be unique. At the same time, the movement of the U-shaped plate 73 will drive the L-shaped long block 77, track block 78, L-shaped slide plate 712, and friction block 711 to move in the track groove of the track plate 79 via the slider 710. This ensures that no matter where the cleaning roller 74 moves, when the L-shaped slide plate 712 moves along the inner wall of the track block 78 with the slider 710 and friction block 711, the rough surface of the friction block 711 will contact the rough surface of the friction wheel 76.

[0027] Please see Figures 1-8Based on the above embodiments, in another embodiment of the present invention, an anti-deviation device 5 is provided on the side of the L-shaped plate 601. The anti-deviation device 5 includes two sawtooth positioning blocks 51, which are respectively fixed on the side of the two L-shaped plates 601. Sawtooth positioning blocks 52 are fixed on both sides of the moving end of the linear motor 3. Vertical plates 53 are fixed on the top of the two L-shaped plates 601. A fixing rod 54 is fixed between the two vertical plates 53. The two moving plates 602 are slidably mounted on the outer wall of the fixing rod 54. A spring 55 is provided between the moving plate 602 and the vertical plate 53. The sawtooth positioning blocks 51 are located on the displacement trajectory of the sawtooth positioning blocks 52. With the above structure, the rotor shaft end that has been drilled is tapped, thereby avoiding the problem that after drilling the rotor shaft end, when tapping it again, slight deviation will occur during tapping due to the inability to specifically position the rotor shaft end, resulting in the scrapping of the rotor shaft end.

[0028] A sponge pad 56 is fixed to the side of the vertical plate 53, and a sponge pad 57 is fixed to the side of the movable plate 602. The sponge pad 56 is located on the displacement trajectory of the sponge pad 57. By setting up the above structure, the impact force of the sawtooth positioning block 52 on the sawtooth positioning block 51 can be reduced, thereby avoiding the problem of inaccurate positioning caused by wear of the sawtooth positioning block 52 and the sawtooth positioning block 51 during long-term use.

[0029] In use, the moving end of the linear motor 3 drives one of the sawtooth positioning blocks 52 to move. The sawtooth of the sawtooth positioning block 52 on that side moves to the sawtooth of its corresponding sawtooth positioning block 51. At this time, the drilling part 23 is aligned with the center of the rotor shaft end, thus completing the positioning of the rotor shaft end driven by the moving end of the linear motor 3. After drilling is completed, when the moving end of the linear motor 3 is started again, the sawtooth of the sawtooth positioning block 52 on the other side of the moving end of the linear motor 3 will be in contact with the sawtooth of its corresponding sawtooth positioning block 51. At this time, the tapping part 24 is aligned with the center of the rotor shaft end, thus tapping the drilled rotor shaft end. This avoids the problem of not being able to accurately position the rotor shaft end for tapping when drilling the rotor shaft end again. Slight deviations may occur, leading to the scrapping of the rotor shaft end. When the linear motor 3 moves, it drives two moving plates 602 to move. Therefore, one moving plate 602 compresses the spring 55 in the direction of movement, and the other moving plate 602 stretches the spring 55 in the opposite direction. The movement of the moving plate 602 also moves the sponge pad 57 to the center of the sponge pad 56. Thus, through the cooperation of the two springs 55 and the impact of the sponge pads 57 and 56 on the vertical plate 53 and the moving plate 602 respectively, the impact force of the sawtooth positioning block 52 on the sawtooth positioning block 51 can be reduced, thereby avoiding wear of the sawtooth positioning block 52 and the sawtooth positioning block 51 during long-term use, which would lead to inaccurate positioning.

[0030] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
