Description

[0002] Curbstones are decorative and protective components used along roads. Currently, some curbstones in residential areas and urban roads require chamfering treatment by processing equipment before leaving the factory.

[0003] A search revealed that Chinese patent application CN216181754U discloses a chamfering device for tabletop processing. It mainly uses a cutting drive mechanism to carry a first cutting motor for forward cutting, and the cutting mounting table is provided for oblique mounting to provide chamfering cutting.

[0004] Compared with existing technologies in related fields, it can be seen that in the process of chamfering, the stone is usually chamfered directly by a cutting tool. The stone on both sides of the processing position is very prone to cracking due to stress accumulation and temperature increase, which affects the quality of processing. Utility Model Content

[0028] like Figures 1-7 As shown, a curbstone chamfering processing device includes a worktable 1, a material conveying mechanism 2 on the side of the worktable 1, a displacement unit fixedly installed on the worktable 1, a frame 9 fixedly installed on the displacement unit, a power unit fixedly installed on the frame 9, an auxiliary unit and a cutting blade mechanism 7 fixedly installed on the power unit, and a positioning clamping mechanism on the material conveying mechanism 2. The material conveying mechanism 2 conveys and feeds the curbstone. After the curbstone is conveyed to the processing position, the positioning clamping mechanism on the material conveying mechanism 2 clamps and fixes the curbstone to prevent it from sliding during processing. After the curbstone is in place, the power unit drives the cutting blade mechanism 7 to chamfer the curbstone. During the processing, the auxiliary unit protects both sides of the chamfered position of the curbstone to prevent stress from causing the curbstone to crack, thus ensuring the quality of the curbstone chamfering. At the same time, the displacement unit moves the power unit and the cutting blade mechanism 7 through the frame 9, enabling chamfering processing at different positions of the curbstone.

[0029] like Figures 1-4 , Figure 6 , Figure 7 As shown, the auxiliary unit includes a support frame 401, which is fixedly mounted on the power unit. A second electrically controlled telescopic mechanism 402 is fixedly mounted at both ends of the support frame 401. A mounting frame 403 is fixedly mounted on the telescopic end of the second electrically controlled telescopic mechanism 402. An infusion unit, a detection component, and a second damping rod 406 are fixedly mounted inside the mounting frame 403. A spring 407 is sleeved on the second damping rod 406. A movable frame 404 is fixedly connected to the telescopic end of the second damping rod 406. The movable frame 404 is slidably mounted inside the mounting frame 403. Elastic rollers 405 are rotatably arranged on the movable frame 404. The second electrically controlled telescopic mechanism 402 operates using existing technology. During the chamfering process of the curbstone, the second electrically controlled telescopic mechanism 402 drives the mounting frame 403 to move. The mounting frame 403 is connected to the second damping rod 406 and... The movable frame 404 drives the elastic roller 405 to adhere to the surface of the curbstone. The force applied by the elastic roller 405 to the surface of the curbstone is detected by the detection component to avoid excessive force that may damage the curbstone. The second damping rod 406 and the spring 407 allow the elastic roller 405 to press flexibly against the curbstone, avoiding hard contact that may damage the surface of the curbstone. During the curbstone chamfering process, the pressing of the elastic roller 405 applies a pre-tightening force to the curbstone, thereby offsetting the processing stress generated by the cutting blade mechanism 7 when chamfering the curbstone. Cold water is sprayed onto the processing position through the liquid infusion unit to cool it down. The elastic roller 405, the second damping rod 406 and the spring 407 buffer and offset the vibration force during processing, effectively reducing edge chipping and thermal cracking on both sides of the curbstone chamfering position, and effectively improving the quality of curbstone chamfering.

[0030] like Figure 4 As shown, the detection assembly includes a pressure sensor 408 and an elastic block 409. The pressure sensor 408 is fixedly installed in the mounting bracket 403, and the elastic block 409 is fixedly installed on the movable bracket 404. The elastic block 409 is slidably connected to the pressure sensor 408, and can continuously apply force to the pressure sensor 408 through the elastic block 409. The deformation of the elastic block 409 avoids affecting the movement of the movable bracket 404. When the elastic roller 405 presses against the surface of the curbstone, the elastic roller 405 drives the elastic block 409 through the movable bracket 404 to apply force to the pressure sensor 408. The pressure sensor 408 detects the applied force, thereby determining the force applied by the elastic roller 405 to the surface of the curbstone. This facilitates the control of the force applied by the elastic roller 405 to the curbstone and avoids damage to the curbstone.

[0031] like Figures 1-3 , Figure 5 , Figure 7 As shown, the power unit includes an angle adjustment mechanism 301 and a first electrically controlled telescopic mechanism 302. The angle adjustment mechanism 301 is fixedly mounted on the frame 9, and the first electrically controlled telescopic mechanism 302 is fixedly mounted on the angle adjustment mechanism 301. A first motor 303 is fixedly mounted on the telescopic end of the first electrically controlled telescopic mechanism 302. A sleeve 304 is fixedly mounted on the output shaft of the first motor 303. A shock-absorbing component is fixedly mounted inside the sleeve 304. The sleeve 304 is slidably connected to the cutting blade mechanism 7, and the cutting blade mechanism 7 is fixedly connected to the shock-absorbing component. The first electrically controlled telescopic mechanism 302 and the first motor 303 operate using existing technology. The angle adjustment mechanism 301 includes a fixed part and a movable part, which are connected by bolts. The angle adjustment mechanism 301 is adjusted by connecting the movable part and the fixed part. The connection angle allows for adjustment of the tilt angle of the cutting blade mechanism 7, facilitating chamfering of the curbstone at different angles. When processing the curbstone, the tilt angle of the cutting blade mechanism 7 is first adjusted via the angle adjustment mechanism 301 according to processing requirements. The first electrically controlled telescopic mechanism 302 drives the sleeve 304 to move via the first motor 303. The sleeve 304, through the shock-absorbing component, moves the cutting blade mechanism 7 to the chamfering position of the curbstone. The first motor 303, through the sleeve 304 and the shock-absorbing component, drives the cutting blade mechanism 7 to rotate, enabling the cutting blade mechanism 7 to chamfer the curbstone. Simultaneously, during processing, the shock-absorbing component buffers and dampens the cutting blade mechanism 7, protecting it and reducing damage caused by vibration.

[0032] like Figure 5As shown, the shock absorption assembly includes a first damping rod 305 and an arc-shaped spring piece 306. Both the first damping rod 305 and the arc-shaped spring piece 306 are fixedly installed inside the sleeve 304. A disc spring assembly 307 is fixedly installed on the telescopic end of the first damping rod 305. The disc spring assembly 307 is fixedly connected to the cutting blade mechanism 7. The arc-shaped spring piece 306 is arranged around the cutting blade mechanism 7 and is fixedly connected to the cutting blade mechanism 7. The connection between the cutting blade mechanism 7 and the sleeve 304 is polygonal, effectively preventing relative rotation between the cutting blade mechanism 7 and the sleeve 304. The cutting blade mechanism 7 performs chamfering processing on the curbstone. During the process, the arc-shaped spring 306 buffers and cancels the vibration force in the circumferential direction of the cutting blade mechanism 7, and the first damping rod 305 and disc spring group 307 buffer and cancel the vibration force in the axial direction. Thus, during the chamfering process, the arc-shaped spring 306, the first damping rod 305 and the disc spring group 307 effectively reduce the vibration of the cutting blade mechanism 7, protect the cutting blade mechanism 7, reduce the damage caused by vibration during the processing, extend the service life of the cutting blade mechanism 7, and enable the cutting blade mechanism 7 to better chamfer the curbstone and ensure the quality of the chamfer.

[0033] like Figure 2 , Figure 4 , Figure 7 As shown, the infusion unit includes a shunt tube 501, a first guide tube 502, and a second guide tube 503. The shunt tube 501 and the first guide tube 502 are fixedly installed on the outer surface of the mounting frame 403. The second guide tube 503 is fixedly installed inside the mounting frame 403 and is located above the movable frame 404. Both the second guide tube 503 and the first guide tube 502 are connected to the shunt tube 501. The shunt tube 501 is connected to an external chilled water delivery device. During the chamfering process of the curbstone, the external chilled water delivery device delivers chilled water into the shunt tube 501. The chilled water is then diverted into the first guide tube 502 and the second guide tube 503 through the shunt tube 501. The first guide pipe 502 sprays out chilled water to cool the contact area between the cutting blade mechanism 7 and the curbstone, preventing temperature rise during processing from affecting the operation of the cutting blade mechanism 7 and protecting it so that it can work continuously and stably. At the same time, it washes away the dust generated during the chamfering process, reducing dust generation and pollution. The chilled water sprayed from the second guide pipe 503 is dispersed onto the surface of the curbstone through the movable frame 404 and the elastic roller 405, thereby cooling both sides of the chamfered area of ​​the curbstone to prevent it from cracking or thermal cracking, effectively avoiding the impact of temperature rise during the chamfering process on the quality of the curbstone chamfering.

[0034] like Figure 1 , Figure 6As shown, the displacement unit includes a lead screw 601 and a second motor 602. The second motor 602 is fixedly installed on the side of the worktable 1, and the lead screw 601 is rotatably installed inside the worktable 1. The lead screw 601 is fixedly connected to the output shaft of the second motor 602. A slide block 603 is installed on the lead screw 601 through a threaded connection. The slide block 603 is slidably connected to the worktable 1 and is fixedly connected to the frame 9. The second motor 602 operates using existing technology. The second motor 602 drives the lead screw 601 to rotate, which in turn drives the slide block 603 to move. The slide block 603 then drives the frame 9 to move, thereby adjusting the position of the cutting blade mechanism 7 on the curbstone, facilitating the chamfering of different positions on the curbstone by the cutting blade mechanism 7.

[0035] like Figure 2 , Figure 7 As shown, dust hoods 8 are fixedly installed on both sides of the support frame 401. The dust hoods 8 are connected to an external dust collection device. During the chamfering process of the curbstone, the external dust collection device absorbs the dust generated during the chamfering process of the curbstone through the dust hoods 8, thereby reducing the pollution of the environment by dust.

[0036] Working principle: such as Figures 1-3 , Figure 5 , Figure 7 As shown, the curbstone is transported to the processing position by the material conveying mechanism 2 and fixed. According to the processing needs, the tilt angle of the cutting blade mechanism 7 is adjusted by the angle adjustment mechanism 301. The sleeve 304 is moved by the first electric telescopic mechanism 302 through the first motor 303. The sleeve 304 moves the cutting blade mechanism 7 to the position of the curbstone chamfering through the shock absorption component.

[0037] like Figures 1-4 , Figure 6 , Figure 7 As shown, the second electrically controlled telescopic mechanism 402 drives the mounting frame 403 to move. The mounting frame 403 drives the elastic roller 405 to fit against the surface of the curbstone through the second damping rod 406 and the movable frame 404. The second damping rod 406 and the spring 407 make the elastic roller 405 flexibly press against the curbstone. The pressure sensor 408 detects the pressing force of the elastic roller 405 and applies a pre-tightening force to the curbstone through the pressing of the elastic roller 405.

[0038] like Figures 1-3 , Figure 5 , Figure 7As shown, the first motor 303 drives the cutting blade mechanism 7 to chamfer the curbstone through the sleeve 304, the first damping rod 305 and the disc spring group 307. During the processing, the elastic roller 405, the second damping rod 406 and the spring 407 buffer and cancel the vibration force during processing, cancel the processing stress, and reduce the cracking of the curbstone. At the same time, the arc-shaped spring 306 buffers and cancels the vibration force in the circumferential direction of the cutting blade mechanism 7, and the first damping rod 305 and the disc spring group 307 buffer and cancel the vibration force in the axial direction, reducing the impact of vibration on the cutting blade mechanism 7 and the chamfering quality of the curbstone.

[0039] like Figure 2 , Figure 4 , Figure 7 As shown, during the chamfering process of the curbstone, an external ice water conveying device delivers ice water into the diversion pipe 501. The ice water is then diverted into the first guide pipe 502 and the second guide pipe 503 through the diversion pipe 501, and sprayed out through the first guide pipe 502 and the second guide pipe 503. The ice water flowing out through the first guide pipe 502 cools the contact area between the cutting blade mechanism 7 and the curbstone. The ice water sprayed out through the second guide pipe 503 is dispersed onto the surface of the curbstone through the movable frame 404 and the elastic roller 405, thereby cooling both sides of the chamfered area of ​​the curbstone. The sprayed ice water also washes away the dust generated during the chamfering process, reducing dust generation and dust pollution.

[0040] like Figure 1 , Figure 6 As shown, the second motor 602 drives the lead screw 601 to rotate, the lead screw 601 drives the slide 603 to move, and the slide 603 drives the frame 9 to move, thereby adjusting the position of the cutting blade mechanism 7 on the curbstone, enabling chamfering processing of different positions of the curbstone;

[0041] like Figure 2 , Figure 7 As shown, during the chamfering process of the curbstone, the external dust collection device absorbs the dust generated during the chamfering process through the dust collection hood 8, reducing the pollution of the environment by the dust.
