Description

Technical Field

[0001] The invention relates to the field of drilling equipment, and more particularly to a cutter head drilling device. Background Art The cutter head plays a vital role in modern machinery. It is mainly used for metal cutting and polishing. The cutter head drilling is a process involving precise drilling of holes on the cutter head. The accuracy of the cutter head drilling directly affects the accuracy and surface quality of the workpiece. During the drilling process of the cutter disc, in order to improve the drilling accuracy of the cutter disc, the cutter disc needs to be clamped and fixed by a punching device. For example, the Chinese patent with the announcement number CN212042772U discloses a punching device for processing a circular scissor blade. The device manually rotates the adjustment bolt so that the extension rod drives the arc-shaped support plate to fix the inner ring of the cutter disc, which can prevent the cutter disc from tilting during the drilling process, thereby effectively reducing the drilling error; When the punching device in the prior art is working, the support rod is tilted to facilitate the cooperation of the arc-shaped support plate to support the cutter disc. However, during the processing of the cutter disc, several groups of connecting holes distributed in a circular shape need to be processed on the surface of the cutter disc. Therefore, in the actual processing process, the position of the cutter disc needs to be adjusted after a group of connecting holes are processed. After the cutter disc is adjusted to the predetermined position, it needs to be clamped and fixed again. Frequent disassembly and installation of the cutter disc is not only time-consuming and labor-intensive, but also reduces the efficiency of the cutter disc punching process.

[0019] By adopting the above technical scheme, when the bridge cutting machine cutter disc 18 is punching, the annular cutter disc 18 is placed on the upper surface of the support plate 14, and the cutter disc 18 is lifted and supported by the support plate 14, and then the support plate 14 is driven to rotate synchronously by the movable rod 12, so that the cutter disc 18 is driven to rotate a certain angle by the support plate 14, and the support plate 14 will drive the contact plate 51 on its surface to rotate synchronously during the rotation process, and the contact plate 51 will slide and contact with the guide rod 57 during the rotation process, and the guide rod 57 will drive the movable part to move synchronously, thereby driving the fixed frame 2 58 to move synchronously through the movable part, and the fixed frame 1 53 movably supports the contact plate 51 through the pin shaft 2 592, and the fixed frame 2 58 will pull the contact plate 51 through the pin shaft 1 59 during the movement, and the two groups of contact plates 51 will gather toward the middle under the action of the pulling force, so that the two The contact plate 51 is pressed into contact with the surface of the cutter disc 18, and the cutter disc 18 is clamped and fixed by the contact plate 51, so that the cutter disc 18 can be clamped and limited during the drilling process of the cutter disc 18, thereby reducing the probability of accidental deviation of the cutter disc 18 during the drilling process. At the same time, there is no need to disassemble and install the cutter disc 18 during the continuous drilling process, which can effectively improve the drilling efficiency while also effectively improving the drilling accuracy and stability of the cutter disc 18. After the drilling is completed, the movable rod 12 continues to be rotated, and the contact plate 51 is driven to rotate synchronously by the movable rod 12. When the arc groove 52 on the surface of the contact plate 51 contacts the guide rod 57, the fixed frame 58 moves in the opposite direction and resets under the elastic force of the movable part, so that the contact plate 51 is out of contact with the cutter disc 18, thereby releasing the clamping and fixation of the cutter disc 18 so that the cutter disc 18 can continue to rotate with the movable rod 12.

[0020] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the fixing frame 1 53 and the fixing frame 2 58 are both U-shaped structures, and a guide groove 56 is provided on the outer surface of the lower end of the fixing frame 1 53. The guide rod 57 passes through the guide groove 56 to the lower side of the fixing frame 1 53. A baffle 54 is fixedly connected to the inner surface of the fixing frame 1 53, and a spring 2 55 is fixedly connected to the outer surface of the baffle 54. The spring 2 55 is fixedly connected to the fixing frame 2 58 at one end away from the baffle 54.

[0021] The number of the contact plates 51 is two groups and they are symmetrically distributed up and down. The end of the contact plate 51 away from the pin shaft 1 59 is rotatably connected to the pin shaft 2 592. The pin shaft 2 592 is fixedly connected to the fixing frame 1 53. The contact plate 51 is in close contact with the outer surface of the cutter disc 18. The number of the arc grooves 52 is several groups and they are distributed in a circular array. A through groove 511 is provided on the outer surface of the upper end of the contact plate 51.

[0022] By adopting the above technical scheme, when the guide rod 57 contacts the surface of the contact plate 51, the guide rod 57 will move toward the side of the baffle plate 54 under the extrusion of the contact plate 51, and the guide rod 57 drives the fixing frame 2 58 to move toward the side of the baffle plate 54 and squeezes the spring 2 55, so that the contact plate 51 is stretched to keep the contact plate 51 and the surface of the cutter disc 18 in close contact. As the contact plate 51 rotates, the surface of the contact plate 51 is in an arc shape, so that the positions of the guide rod 57 and the fixing frame 2 58 can be kept stable. When the arc groove 52 on the surface of the contact plate 51 rotates to the side of the guide rod 57, the fixing frame 2 58 drives the guide rod 57 to keep in close contact with the surface of the arc groove 52 under the elastic force of the spring 2 55, so as to adjust the positions of the guide rod 57 and the fixing frame 2 58, and the baffle 54 on the inner side of the fixing frame 1 53 can fix and support the spring 2 55.

[0023] like Figure 1 , Figure 4 and Figure 5 As shown, the interior of the operating table 11 is hollow, and a supporting assembly is arranged on the upper side of the operating table 11, and the supporting assembly includes a bearing 13 rotatably connected to the inner wall of the operating table 11, the lower end of the movable rod 12 passes through the inner side of the operating table 11 and is fixedly connected to the bearing 13, the outer surface of the movable rod 12 is threadedly connected with a locking sleeve 17, and the locking sleeve 17 is in close contact with the outer surface of the upper end of the cutter disc 18, the upper outer surface of the support plate 14 is provided with a receiving groove 16, and the inner surface of the receiving groove 16 is fixedly connected with a contact sleeve 15, and the contact sleeve 15 is in the shape of a hollow ring, and the upper outer surface of the contact sleeve 15 is in close contact with the lower outer surface of the cutter disc 18, and the upper outer surface of the operating table 11 is fixedly connected with a surrounding plate 19, and the surrounding plate 19 is in the shape of a ring.

[0024] By adopting the above technical scheme, before the cutter disc 18 is drilled, the cutter disc 18 is stably placed on the upper surface of the support plate 14, and the cutter disc 18 is lifted and supported by the support plate 14, and then the operator twists the locking sleeve 17, and the locking sleeve 17 will fit on the surface of the cutter disc 18 during the rotation process, and the cutter disc 18 is locked and fixed by the locking sleeve 17 and the support plate 14. After the cutter disc 18 is placed on the surface of the support plate 14, it will fit and contact with the surface of the contact sleeve 15, and the contact sleeve 15 will be squeezed under the gravity of the cutter disc 18. The receiving groove 16 on the surface of the support plate 14 can accommodate and support the contact sleeve 15, and the contact sleeve 15 is hollow and can expand to a certain extent. Under the action of the squeezing force, the contact sleeve 15 will keep a close fit with the lower surface of the cutter disc 18, thereby increasing the friction between the contact sleeve 15 and the cutter disc 18, and by making the cutter disc 18 clamped more firmly, the clamping quality of the cutter disc 18 can be improved, and then the drilling accuracy of the cutter disc 18 can be further improved.

[0025] like Figure 1 , Figure 5, Figure 5 and Figure 8 As shown, a driving assembly is arranged on the upper side of the operating table 11, and the driving assembly includes a support plate 21 fixedly connected to the outer surface of the upper end of the operating table 11, a servo motor 22 is fixedly connected to the outer surface of the support plate 21, a pressure rod 28 is fixedly connected to the left end of the output shaft of the servo motor 22, a friction sleeve 29 is fixedly connected to the outer surface of the pressure rod 28, and the friction sleeve 29 is in an arc shape. The outer surface of the friction sleeve 29 is in rotational contact with the outer surface of the lower end of the cutter disc 18.

[0026] The outer surface of the support plate 21 is provided with a slide groove 25, and the inner surface of the slide groove 25 is slidably connected with a slide sleeve 24, and the slide sleeve 24 is in a circular ring shape. The inner surface of the slide sleeve 24 is rotatably connected with a pressure rod 23, and the outer surface of the pressure rod 23 is fixedly connected with a friction sleeve 27. The friction sleeve 27 is located directly above the friction sleeve 29 and is rotatably in contact with the outer surface of the cutter disc 18. The upper side of the outer surface of the slide sleeve 24 is fixedly connected with a spring 26, and the upper end of the spring 26 is fixedly connected to the upper side of the inner surface of the slide groove 25. The outer surface of the friction sleeve 27 is evenly provided with spiral grooves 291.

[0027] By adopting the above technical solution, the connecting holes of the cutter disc 18 of the bridge cutting machine are usually distributed in a circular ring shape. When a group of drilling holes is completed, the clamping assembly releases the clamping fixation of the cutter disc 18, and then the servo motor 22 is started and operated. The output shaft of the servo motor 22 drives the pressure rod 28 to rotate synchronously, thereby driving the friction sleeve 29 to rotate synchronously through the pressure rod 28. The friction sleeve 29 is in contact with the surface of the cutter disc 18. As the friction sleeve 29 rotates, it drives the cutter disc 18 to rotate a certain angle. The support plate 21 slidingly supports the sliding sleeve 24 through the sliding groove 25, thereby supporting the pressure rod 1 23 through the sliding sleeve 24. The pressure rod 1 23 drives the friction sleeve 1 27 to keep in contact with the surface of the cutter disc 18. The spiral groove 291 on the surface of the friction sleeve 1 27 can not only increase the friction The friction between the friction sleeve 27 and the cutter disc 18, and during the rotation process, the spiral groove 291 can assist in the discharge of iron filings on the surface of the cutter disc 18, and reduce the residual iron filings on the surface of the cutter disc 18. At the same time, under the elastic force of the spring 26, the sliding sleeve 24 can drive the friction sleeve 27 to keep close contact with the surface of the cutter disc 18 through the pressure rod 23, so that the friction sleeve 27 and the friction sleeve 29 can evenly maintain sufficient friction with the cutter disc 18, and then the cutter disc 18 can be driven to rotate smoothly through the friction sleeve 27 and the friction sleeve 29. By controlling and adjusting the speed and working time of the servo motor 22, the rotation angle of the cutter disc 18 can be adjusted, and the cutter disc 18 can also be rotated at the same angle, thereby further improving the drilling accuracy of the cutter disc 18. like Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, a drilling assembly is provided on the outer surface of the support rod 33, and the drilling assembly includes a limit bar 34 fixedly connected to the outer surface of the support rod 33, and the support rod 33 is slidably connected to the connecting frame 32 through the limit bar 34, and a fixing plate 38 is fixedly connected to the outer surface of the support rod 33, and an electric telescopic rod 39 is fixedly connected to the outer surface of the lower end of the connecting frame 32.

[0028] The lower end of the electric telescopic rod 39 is fixedly connected to the fixing plate 38, and the end of the connecting frame 32 away from the support rod 33 is fixedly connected to the connecting seat 35, the lower end of the connecting seat 35 is fixedly connected to the motor 36, and the lower end of the output shaft of the motor 36 is fixedly connected to the drill bit 37.

[0029] By adopting the above technical solution, after the cutter disc 18 is clamped in place, the motor 36 and the electric telescopic rod 39 are started and operated respectively, the support rod 33 fixes and supports the fixed plate 38, and the fixed plate 38 lifts and supports the electric telescopic rod 39. As the electric retractable rod retracts inward, the electric telescopic rod 39 will drive the connecting frame 32 to slide downward along the surface of the support rod 33. The limit strip 34 on the surface of the support rod 33 can guide the sliding of the connecting frame 32, so that the sliding of the connecting frame 32 is more stable. During the downward movement of the connecting frame 32, the connecting seat 35 will be driven to move synchronously, thereby driving the motor 36 to move downward synchronously through the connecting seat 35. At the same time, the output shaft of the motor 36 drives the drill bit 37 to rotate at high speed. The drill bit 37 rotates at high speed and moves downward synchronously, so that the drill bit 37 contacts the surface of the cutter disc 18, and the cutter disc 18 is drilled by the drill bit 37.

[0030] like Figure 2 , Figure 5 and Figure 7 As shown, a cooling component is arranged on the upper side of the fixed plate 38, and the cooling component includes a capsule 43 fixedly connected to the outer surface of the upper end of the fixed plate 38, and the capsule 43 is in the shape of a hollow circular ring. The outer surface of the upper end of the capsule 43 is fixedly connected to a pressure plate 41, and the outer surface of the lower end of the connecting frame 32 is fixedly connected to a pull rod 49, and the lower end of the pull rod 49 is fixedly connected to the pressure plate 41. The number of the pull rods 49 is two groups and they are symmetrically distributed. The outer surface of the upper end of the operating table 11 is fixedly connected to a discharge trough 48, and the number of the discharge troughs 48 is several groups and they are distributed in a ring array. The outer surface of the fixed plate 38 is provided with a through hole 44.

[0031] An air inlet pipe 42 is fixedly connected to the outer surface of the upper end of the sac body 43, and the upper end of the air inlet pipe 42 passes through the upper side of the pressure plate 41 and is fixedly connected to the pressure plate 41; an exhaust pipe 45 is fixedly connected to the outer surface of the lower end of the sac body 43, and an air guide pipe 46 is fixedly connected to the lower end of the exhaust pipe 45, and the air guide pipe 46 is in a circular ring shape, and is fixedly connected to the outer surface of the lower end of the fixing plate 38; a nozzle 47 is fixedly connected to the lower side of the outer surface of the air guide pipe 46, and the number of the nozzles 47 is several groups and distributed in a ring array.

[0032] By adopting the above technical solution, during the drilling process, as the connecting frame 32 moves downward, the pull rod 49 will be driven to move downward synchronously, and the pull rod 49 will drive the pressure plate 41 to move downward synchronously. The support rod 33 supports the capsule 43 through the fixing plate 38, and the pressure plate 41 will squeeze the capsule 43 during the downward movement. The gas inside the capsule 43 is injected into the air guide pipe 46 through the exhaust pipe 45 under the action of pressure, and then transported to the inside of the nozzle 47 through the air guide pipe 46, and evenly sprayed out through the nozzles 47 distributed in a ring shape. The gas sprayed by the nozzle 47 is blown on the surface of the drill bit 37, which can not only blow and clean the iron filings attached to the surface of the drill bit 37, reduce the residual iron filings on the surface of the drill bit 37, and reduce the probability of the drill bit 37 being accidentally stuck, but also can be blown to cool the drill bit 37, thereby reducing the working temperature of the drill bit 37 to a certain extent. Temperature, reducing the probability of damage of the drill bit 37 due to excessive temperature, thereby being able to extend the service life of the drill bit 37 to a certain extent, and improving the operating stability of the drilling device of the cutter disc 18. Under the blowing action of the gas, the iron filings on the surface of the cutter disc 18 will be blown onto the contact plate 51 and the upper surface of the operating table 11, and the iron filings on the surface of the contact plate 51 will fall onto the surface of the operating table 11 through the through groove 511. The surrounding plate 19 can to a certain extent prevent the iron filings from diffusing to the surroundings, thereby reducing the difficulty of cleaning the iron filings. The iron filings on the surface of the operating table 11 will be collected into the interior of the operating table 11 through the discharge trough 48 for centralized collection and treatment, thereby being able to improve the utilization efficiency of iron resources to a certain extent. When the connecting frame 32 drives the motor 36 to move upward, the pressing plate 41 cooperates with the fixing plate 38 to stretch the capsule 43. At this time, external air enters the capsule 43 through the air inlet pipe 42 to expand and reset the capsule 43.

[0033] Instructions for use: When drilling a hole with the cutter disc 18, first place the annular cutter disc 18 on the upper surface of the support plate 14, lift and support the cutter disc 18 through the support plate 14, and then the operator twists the locking sleeve 17, which will fit on the surface of the cutter disc 18 during the rotation, and lock and fix the cutter disc 18 through the locking sleeve 17 and the support plate 14, and the contact sleeve 15 will keep close contact with the lower surface of the cutter disc 18 under the action of the extrusion force, thereby increasing the friction between the contact sleeve 15 and the cutter disc 18, making the cutter disc 18 clamped more firmly, and then the electric telescopic rod 39 drives the motor 36 to move downward synchronously through the connecting seat 35, and at the same time, the output shaft of the motor 36 drives the drill bit 37 to rotate at a high speed, and the drill bit 37 rotates at a high speed and moves downward synchronously to perform the cutter disc 18 drilling processing, and during the drilling process, the pull rod 49 drives the pressure plate 41 to move downward synchronously, and the pressure plate 41 will squeeze the capsule 43 during the downward movement, and the gas is blown out through the nozzle 47. Blowing on the surface of the drill bit 37 can not only blow and clean the iron filings attached to the surface of the drill bit 37, but also can cool the drill bit 37 by air. After a group of drilling is completed, the friction sleeve 29 is in contact with the surface of the cutter disc 18. As the friction sleeve 29 rotates, the cutter disc 18 will be driven to rotate a certain angle. The support plate 14 will drive the contact plate 51 on its surface to rotate synchronously during the rotation. The surface of the contact plate 51 will slide in contact with the guide rod 57 during the rotation. The fixed frame 2 58 will pull the contact plate 51 through the pin 1 59 during the movement. The two groups of contact plates 51 will gather toward the middle under the action of the pulling force, so that the two groups of contact plates 51 are squeezed and contacted with the surface of the cutter disc 18, and the cutter disc 18 is clamped and fixed by the contact plate 51, so that the cutter disc 18 can be clamped and limited during the drilling process of the cutter disc 18, thereby reducing the probability of accidental displacement of the cutter disc 18 during the drilling process.
