Description

Technical Field

[0002] Driven by the "dual carbon" goal, new energy trucks, with their core advantages of low carbon emissions, environmental friendliness, and low operating costs, have become a core direction for the transformation and upgrading of the logistics and transportation industry, and are widely used in diverse scenarios such as urban delivery, long-distance transportation, and infrastructure projects. As the core load-bearing component of new energy trucks, the structural design and processing precision of the truck body directly affect the vehicle's load-bearing capacity, sealing performance, lightweight level, and service life. Cutting and processing are core processes in truck body manufacturing, encompassing multiple stages such as sheet metal cutting, irregular openings, profile cutting, and beveling, directly determining the assembly precision and manufacturing efficiency of the truck body. During the production of new energy truck bodies, it may be necessary to create square or circular slots on the inner walls of the truck body. Square slots can be used to accommodate square equipment such as air conditioners, while circular slots are used to install equipment such as pipes. However, the following drawbacks still exist: When cutting a square groove with a cutting machine, manual cutting is not stable and it is inconvenient to cut straight groove edges. It also requires cutting each of the four sides one by one, which is slow. When cutting a circular groove, it is not easy to make arc cuts and the cutting stability is poor. Summary of the Invention

[0013] Compared with the prior art, the beneficial effects of the present invention are: (1) In this invention, the guide rod is located in the guide groove, which can linearly limit the moving frame, making it convenient for the cutting machine to move along a straight line, and thus making it convenient to cut a square groove on the inner wall of the new energy truck compartment. The guide rod is located in the fixed groove, which can fix the moving frame and the rotating gear, making it convenient for the two cutting machines to move in a circular motion, and thus making it convenient to cut a circular groove on the inner wall of the new energy truck compartment. (2) In this invention, the rotating gear meshes with the rack. When the end of the guide rod is inside the guide groove, the rotating gear can drive the moving frame to move linearly, thereby driving the two cutting machines to move linearly and cut square grooves. When the end of the guide rod is inserted into the fixed groove, the rotating gear can drive the two cutting machines to make circular motion and cut circular grooves.

After the gear in the middle rotates, the two cutting machines can be driven to move relative to each other through the two tooth plates, which makes it convenient to adjust the distance between the two cutting machines. This facilitates the cutting and forming of square grooves of different sizes and circular grooves of different diameters. Furthermore, the two cutting machines can cut both sides of the square groove simultaneously, thereby improving the cutting efficiency. (4) In this invention, after the suction cup end face contacts the inner wall of the new energy truck compartment, the push plate is pushed towards the inner wall of the compartment, so that negative pressure is generated inside the suction cup to center the equipment, which facilitates the equipment to cut square grooves with the suction cup axis as the axis of symmetry, and to cut circular grooves with the suction cup axis as the axis. (5) In this invention, the push plate moves toward the inner wall of the carriage, so that the suction cup and the inner wall of the carriage are negatively pressured to achieve fixed positioning. When cutting, the push plate is pushed to continue moving toward the inner wall of the carriage, so that the cutting machine cuts a notch on the inner wall of the carriage to facilitate subsequent cutting. After continuing to push, the negative pressure between the suction cup and the inner wall of the carriage is increased, thereby improving the cutting stability. Attached Figure Description

[0017] Example 1, by Figures 1-3 This invention relates to a cutting device for the cargo box of a new energy truck, comprising a movable cutting assembly 1. The movable cutting assembly 1 includes a mounting frame 11, with cutting machines 12 mounted at both the upper and lower ends of the mounting frame 11. A movable connecting member 17 is provided between the two cutting machines 12. A limiting sleeve 18 is fixedly installed on the side of the mounting frame 11 near the movable connecting member 17. Two toothed plates 13 are slidably mounted inside the mounting frame 11, with the ends of the two toothed plates 13 respectively fixedly connected to the two cutting machines 12. A central gear 14 is provided in the middle between the two toothed plates 13. The central gear 14 meshes with the toothed plates 13 on both sides. The central gear 14 is fixedly connected to the output shaft of the first motor 15. The first motor 15 is mounted on the mounting frame 11. Two cutting machines 12 are symmetrically arranged at both ends of the mounting frame 11. After the central gear 14 rotates, it can drive the two cutting machines 12 to move relative to each other through the two toothed plates 13. This makes it easy to adjust the distance between the two cutting machines 12, thereby facilitating the cutting and forming of square grooves of different sizes and circular grooves of different diameters. Furthermore, the two cutting machines 12 can simultaneously cut both sides of the square groove, improving cutting efficiency. Depend on Figure 4 The movable connector 17 includes a movable frame 171 disposed between two cutting machines 12. A rack 172 is installed on the inner top wall of the movable frame 171. Limiting arms 173 are symmetrically installed at the upper and lower ends of the movable frame 171. Two limiting grooves 16 are symmetrically opened on the mounting bracket 11. The two limiting arms 173 are slidably installed inside the two limiting grooves 16 respectively. Two guide grooves 174 are symmetrically opened on both sides of the movable frame 171. The two guide grooves 174 are respectively disposed on both sides of the inner cavity of the movable frame 171. A fixing slot 175 is opened in the middle of the guide groove 174. A central positioning component 2 is provided on the movable frame 171.

[0018] Depend on Figure 5 The central positioning component 2 includes a negative pressure fixing component 21, which is used to fix the negative pressure to the inner wall of the new energy truck compartment to achieve positioning. The end of the negative pressure fixing component 21 is provided with a rotation drive component 22, which is located inside the moving frame 171. The rotation drive component 22 cooperates with the guide groove 174 to achieve linear movement guidance. The rotation drive component 22 cooperates with the fixing slot 175 to achieve equipment rotation. A pushing cutter 23 is provided between the mounting frame 11 and the rotating drive component 22. The pushing cutter 23 is used to push the cutting machine 12 to generate pressure on the new energy truck compartment, thereby achieving cutting. Depend on Figures 7-8The rotating drive component 22 includes a rotating gear 221 disposed inside the moving frame 171. The rotating gear 221 meshes with a rack 172. End plates 222 are symmetrically mounted at both ends of the rotating gear 221. The two end plates 222 are symmetrically disposed on both sides of the moving frame 171. A snap-fit ​​positioning component is symmetrically disposed on the side of the two end plates 222 that is far apart from each other. The snap-fit ​​positioning component includes a side cylinder 225 symmetrically mounted on the side of the two end plates 222 that is far apart from each other. A guide rod 226 is movably mounted inside the side cylinder 225. One end of the guide rod 226 passes through the two end plates 222, and the ends of the four guide rods 226 are respectively snapped into the fixing slots 175 in the four guide grooves 174. The guide rods 226 are located in the guide grooves 174 and can linearly limit the moving frame 171, so that the cutting machine 12 can move along a straight line, thereby facilitating the square groove cutting of the inner wall of the new energy truck body. The guide rod 226 is located in the fixed slot 175, which can fix the moving frame 171 and the rotating gear 221, so as to facilitate the circular movement of the two cutting machines 12 and thus facilitate the circular groove cutting of the inner wall of the new energy truck body. The other end of the guide rod 226 is fixedly installed with a spring 227, one end of the spring 227 is fixedly connected to the inner wall of the end of the side cylinder 225. A magnet 228 is installed on the guide rod 226, and an electromagnet 229 is installed at the end of the side cylinder 225. The rotating gear 221 is meshed with the rack 172. When the end of the guide rod 226 is located inside the guide groove 174, the rotation of the rotating gear 221 can drive the moving frame 171 to move linearly, and thus drive the two cutting machines 12 to move linearly to perform square groove cutting. When the end of the guide rod 226 is inserted into the fixed slot 175, the rotating gear 221 rotates, which can drive the two cutting machines 12 to perform circular groove cutting.

[0019] Depend on Figures 6-9The negative pressure fixing component 21 includes a fixing cylinder 212 rotatably mounted on an end plate 222 on the side away from the mounting bracket 11. A suction cup 211 is fixedly mounted on the end of the fixing cylinder 212. A negative pressure chamber 213 is formed inside the fixing cylinder 212 and communicates with the suction cup 211. A mounting groove 223 is formed inside the fixing cylinder 212, and a second motor 224 is installed inside the mounting groove 223. The output shaft of the second motor 224 is coaxially and fixedly connected to the rotating gear 221. Two limiting rings 214 are installed circumferentially on the fixing cylinder 212, and the negative pressure chamber 213 is circumferentially... An angled connecting hole 215 is provided, which is located between two limiting rings 214. A negative pressure ring sleeve 216 is rotatably installed between the two limiting rings 214. A rotating sealing ring is provided between the negative pressure ring sleeve 216 and the outer wall of the fixed cylinder 212. Side boxes 217 are symmetrically installed on both sides of the negative pressure ring sleeve 216. The side boxes 217 are connected to the negative pressure ring sleeve 216. A piston block 218 is movably installed inside the side box 217. A pull rod 219 is fixedly installed on the side of the piston block 218 away from the negative pressure ring sleeve 216. One end of the pull rod 219 extends through to the outside of the side box 217.

[0020] Depend on Figure 9 The push-cutting component 23 includes an annular groove 231 circumferentially formed on the end plate 222 near the mounting bracket 11. A connecting ring 232 is rotatably mounted inside the annular groove 231. Side plates 233 are symmetrically mounted on both sides of the connecting ring 232. Push rods 236 are movably mounted on the inner side of the side plates 233. A push plate 234 is provided on the inner side of the limiting sleeve 18. The push plate 234 is fixedly connected to the two push rods 236. A gripping rod 235 is symmetrically mounted on the side of the push plate 234 away from the connecting ring 232. The push rods 236 correspond one-to-one with the pull rods 219. A connecting rod 237 is hinged to the end of the push rod 236. The other end of the connecting rod 237 is hinged to the end of the pull rod 219 located outside the side box 217. A suction cup is also included. After the end face of suction cup 211 contacts the inner wall of the new energy truck compartment, it pushes the push plate 234 toward the inner wall of the compartment, creating negative pressure inside the suction cup 211 to center the equipment. This facilitates square groove cutting with the axis of suction cup 211 as the axis of symmetry, as well as circular groove cutting with the axis of suction cup 211 as the axis. The push plate 234 moves toward the inner wall of the compartment, creating negative pressure between the suction cup 211 and the inner wall of the compartment for fixed positioning. During cutting, the push plate 234 continues to move toward the inner wall of the compartment, causing the cutting machine 12 to cut a notch in the inner wall of the compartment, facilitating subsequent cutting. Continuing to push increases the negative pressure between the suction cup 211 and the inner wall of the compartment, thereby improving cutting stability.

[0021] Working principle: When square groove cutting is required, the end of the suction cup 211 is pressed tightly against the inner wall of the new energy truck compartment. Then, the push plate 234 is kept in a horizontal position and the mounting frame 11 is kept in a vertical position. Then, the operator pushes the push plate 234 towards the new energy truck compartment by holding the lever 235. Since the push plate 234 is located inside the limiting sleeve 18, it pushes the mounting frame 11 and the two upper and lower cutting machines 12 towards the new energy truck compartment. During the movement of a short distance, the push rod 236 pulls the piston block 218 in the side box 217 away from the negative pressure ring sleeve 216 through the connecting rod 237. This generates negative pressure in the suction cup 211, which fixes the suction cup 211 with negative pressure between it and the inner wall of the new energy truck compartment, improving cutting stability and achieving positioning fixation. Then the first motor 15 is turned on, driving the central gear 14 to rotate. The central gear 14 meshes with the toothed plates 13 on both sides. The two toothed plates 13 are fixedly connected to the two cutting machines 12 respectively, thereby driving the two cutting machines 12 to move relative to each other, so as to adjust the distance between the two cutting machines 12 according to the length and width of the square groove. Then, each electromagnet 229 is energized to attract the magnetic block 228, thereby driving the guide rod 226 to leave the fixed slot 175 while still inside the guide groove 174. At this time, the outer wall of the guide rod 226 contacts the inner wall of the guide groove 174 to achieve guidance. After the second motor 224 is turned on, the rotating gear 221 is driven to rotate. Since the rotating gear 221 is meshed with the rack 172, the moving frame 171, the mounting bracket 11 and the two cutting machines 12 are driven to move horizontally synchronously to cut the horizontal edge of the square groove. When making horizontal cuts, the push plate 234 is pushed to move towards the inner wall of the new energy truck body, so that the cutting machine 12 first cuts a notch in the new energy truck body, then moves to one side and then to the other side to complete the horizontal cut. In the process of continuing to push the push plate 234 to move, the negative pressure between the suction cup 211 and the inner wall of the new energy truck body is increased, thereby improving the cutting stability. After the horizontal edge of the square groove is cut, the moving frame 171, the mounting bracket 11 and the two cutting machines 12 are moved back to their original positions by rotating the gear 221. The electromagnet 229 is de-energized, so that the guide rod 226 is re-clamped into the fixed slot 175 under the elastic force of the spring 227, and the end plate 222 and the moving frame 171 are clamped and fixed. Push the push plate 234 back to pull the cutting wheel of the cutting machine 12 out of the cutting seam, but still maintain the negative pressure between the suction cup 211 and the inner wall of the new energy truck compartment. Then turn on the second motor 224 to drive the rotating gear 221 to rotate 90 degrees, thereby rotating the moving frame 171 from the horizontal state to the vertical state. Then repeat the above operation to readjust the distance between the two cutting machines 12 so that the two cutting machines 12 move to both ends of the horizontal cutting seam, and then cut the other two sides of the square groove. When circular groove cutting is required, the equipment is first fixed and positioned under negative pressure by suction cup 211. Then, the first motor 15 drives the two cutting machines 12 to move relative to each other so that the positions of the two cutting machines 12 match the diameter of the circular groove to be cut. Then, the push plate 234 is pushed towards the inner wall of the new energy truck compartment, and the two cutting machines 12 cut two notches on the inner wall. Then, the second motor 224 is turned on to drive the rotating gear 221 to rotate, which in turn drives the moving frame 171 to rotate, causing the two cutting machines 12 to move in a circular motion to achieve the cutting of the circular groove.
