Description

Technical Field

[0001] This application relates to the field of wood processing equipment technology, and more specifically, to a high-precision board cutting machine. Background Technology

[0002] In current sheet metal cutting machines, when cutting long sheets, the low precision of the baffle adjustment makes it difficult to achieve accurate positioning when determining the cutting width. This easily leads to significant deviations in the cut surface, affecting the cutting quality and the usability of the sheet metal.

[0003] Furthermore, the graduations on the baffle are typically laser-engraved onto the worktable. Over time, the worktable experiences various frictions and impacts during daily operation, easily causing wear on the laser-engraved graduations. Once worn, the graduations become blurred and difficult to read accurately. Additionally, the work environment often contains a large amount of dust and impurities such as sawdust from cutting materials. This dust and sawdust easily adhere to the graduations, affecting the operator's ability to observe the markings.

[0004] Therefore, it is necessary to develop a high-precision sheet metal cutting machine to solve the problems of low baffle adjustment accuracy and difficulty in observing the scale. Utility Model Content

[0005] This application provides a high-precision sheet metal cutting machine, including a cutting table, a width adjustment mechanism, and a clamping mechanism. The cutting table includes a worktable, a saw blade, and a drive motor. The saw blade protrudes from the surface of the worktable, and the drive motor is located below the worktable and connected to the saw blade. The worktable has slots perpendicular to the saw blade on both sides. The width adjustment mechanism is located on the upper surface of the worktable, on one side of the saw blade, and includes a fixed plate, an adjusting plate, a T-shaped guide rod, an L-shaped guide rod, and a locking stud. The fixed plate is fixed to the edge of the worktable and parallel to the surface of the saw blade. The adjusting plate is located between the saw blade and the fixed plate, and its bottom extends to form a clamping portion adapted to the slots. One end of the T-shaped and L-shaped guide rods is fixed to one side of the adjusting plate, and the other end passes through the fixed plate and is slidable. The upper surfaces of the T-shaped and L-shaped guide rods are flush with the upper surface of the fixed plate. The upper surface of the fixing plate has indicator arrows engraved on both sides of the through-hole. The upper surfaces of both the T-shaped and L-shaped guide rods have two symmetrically arranged scale strips along their length. Locking studs are located on the sides of both ends of the fixing plate to lock the L-shaped guide rods. The clamping mechanism is located on the side of the saw blade away from the width adjustment mechanism and can slide along the slot, used to press the wood board against the adjustment plate before cutting.

[0006] In some embodiments, the two slots formed on each side of the saw blade by the workbench are parallel to each other.

[0007] In some embodiments, the T-shaped guide rod is located in the middle of the fixing plate, and the two L-shaped guide rods are located at both ends of the fixing plate and are symmetrical about the T-shaped guide rod.

[0008] In some embodiments, the T-shaped guide rod is inverted, and the "L" of the L-shaped guide rod faces the T-shaped guide rod.

[0009] In some embodiments, the clamping mechanism includes a movable plate, a fastening stud, and a pressure plate; the movable plate is disposed on the upper surface of the workbench, the bottom end of the fastening stud is provided with a locking block adapted to the locking slot, the fastening stud passes through the locking slot and the lower upper surface of the movable plate, and protrudes from the upper surface of the movable plate, and the screw portion at the top of the fastening stud is provided with a wing nut; the pressure plate is between the movable plate and the saw blade, the pressure plate is provided with a guide post on the side facing the movable plate, the free end of the guide post passes through the movable plate and is provided with a pin, and a spring sleeved on the guide post is provided between the pressure plate and the movable plate.

[0010] In some embodiments, the pressure plate has a mounting groove on its surface facing the saw blade, and multiple vertical rollers are arranged in the groove along the cutting direction of the wood board, with the curved portion of the rollers protruding from the surface of the pressure plate.

[0011] In some embodiments, the pressure plate and the adjusting plate form an outward-curving guide edge at the end where the wooden board enters, to facilitate the entry of the wooden board.

[0012] The cutting machine of this application solves two key problems of traditional cutting machines: low baffle adjustment accuracy and easy loosening of positioning, and easy wear and contamination of the worktable scale leading to reading difficulties. It adopts an innovative double guide rod (T-type + L-type) constraint and slot guide structure design, combined with a reading system with double scale strips and fixed indicator arrows set on the upper surface of the guide rods. This achieves high precision, stable adjustment and reliable maintenance of the cutting width of the plate, and significantly improves the cutting quality and efficiency.

[0023] Please see Figure 1 , Figure 2 and Figure 3This application discloses a high-precision sheet metal cutting machine 100, comprising a cutting table 10, a width adjustment mechanism 20, and a clamping mechanism 30. The cutting table 10 includes a worktable 11, a saw blade 12, and a drive motor 13. The saw blade 12 protrudes from the surface of the worktable 11, and the drive motor 13 is located below the worktable 11 and connected to the saw blade 12. The worktable 11 has slots 111 perpendicular to the saw blade 12 on both sides. The width adjustment mechanism 20 is located on the upper surface of the worktable 11 on one side of the saw blade 12 and includes a fixing plate 21, an adjusting plate 22, a T-shaped guide rod 23, an L-shaped guide rod 24, and a locking stud 25. The fixing plate 21 is fixed to the edge of the worktable 11 and parallel to the surface of the saw blade 12. The adjusting plate 22 is located between the saw blade 12 and the fixing plate 21, and the bottom of the adjusting plate 22 extends to form a clamping portion 221 adapted to the slots 111. One end of the T-shaped guide rod 23 and the L-shaped guide rod 24 are fixed to one side of the adjusting plate 22, and the other end passes through the fixing plate 21 and can slide. The upper surfaces of the T-shaped guide rod 23 and the L-shaped guide rod are flush with the upper surface of the fixing plate 21. The upper surface of the fixing plate 21 has indicator arrows 211 engraved on both sides of the through-hole. The upper surfaces of the T-shaped guide rod 23 and the L-shaped guide rod 24 are symmetrically arranged with two scale strips 231 along the length direction. Locking studs 25 are provided on both sides of the fixing plate 21 to lock the L-shaped guide rod 24. The clamping mechanism 30 is provided on the side of the saw blade 12 away from the width adjusting mechanism 20 and can slide along the slot 111 to clamp the wood board toward the adjusting plate 22 before cutting.

[0024] The cutting machine 100 of this application, through an innovative structural design of dual guide rods (T-type + L-type) constraint and guide groove 111, combined with a reading system of dual scale strips 231 and fixed indicator arrows 211 optimized on the upper surface of the guide rods, solves two key problems of traditional cutting machines 100: low baffle adjustment accuracy and easy loosening of positioning, and easy wear and contamination of the scale of the worktable 11 leading to reading difficulties. It achieves high precision, stable adjustment and reliable maintenance of the cutting width of the plate, significantly improving cutting quality and efficiency.

[0025] Please see Figure 1 and Figure 2 The cutting table 10 includes a worktable 11, a saw blade 12, and a drive motor 13. The saw blade 12 protrudes outward from the tabletop portion of the worktable 11, and the worktable 11 provides sufficient operating range and space on both sides of the saw blade 12 for cutting the wood. The drive motor 13 is located below the worktable 11 and is connected to the saw blade 12 directly or indirectly. The worktable 11 has slots 111 perpendicular to the saw blade 12 on both sides, for the width adjustment mechanism 20 and the clamping mechanism 30 to hold and slide. More specifically, each side of the saw blade 12 has two parallel slots 111. The cross-section of the slots 111 is stepped or dovetail-shaped.

[0026] Please see Figure 1 , Figure 2 and Figure 4 The width adjustment mechanism 20 is located on the upper surface of the workbench 11, on one side of the saw blade 12, and is used to adjust the width of the wood cutting. The width adjustment mechanism 20 includes a fixed plate 21, an adjusting plate 22, a T-shaped guide rod 23, an L-shaped guide rod 24, and a locking stud 25.

[0027] The fixing plate 21 is fixed to the edge of the workbench 11, and its surface is parallel to the surface of the saw blade 12. The fixing plate 21 has T-shaped holes 212 and L-shaped holes 213 penetrating both surfaces. The T-shaped hole 212 is inverted and located in the middle of the fixing plate 21, while the two L-shaped holes 213 are located at both ends of the fixing plate 21 and are symmetrical about the T-shaped hole 212. The tops of the T-shaped holes 212 and L-shaped holes 213 penetrate the upper surface of the fixing plate 21, and indicator arrows 211 are engraved on both sides of the penetration at the middle of the upper end of the fixing plate 21.

[0028] The adjusting plate 22 is located between the saw blade 12 and the fixed plate 21. It can move closer to or further away from the saw blade 12. The distance between the saw blade 12 and the adjusting plate 22 is the width that needs to be retained when cutting the wood. The bottom of the adjusting plate 22 extends downward to form a retaining part 221 that matches the slot 111. The two cooperate with each other to ensure that the adjusting plate 22 slides smoothly on the worktable 11. The retaining part 221 is fixed by a screw that extends into the thread of the adjusting plate 22.

[0029] One end of the T-shaped guide rod 23 is fixed to the side of the adjusting plate 22 facing away from the saw blade 12, and the other end passes through the T-shaped hole 212 and can slide relative to the fixed plate 21. The upper surface of the T-shaped guide rod 23 has scale bars 231 along its length. More specifically, two scale bars 231 are symmetrically arranged on both sides of the top of the T-shaped guide rod 23 where it contacts the fixed plate 21. With the cooperation of the scale bars 231 and the indicator arrows 211, the operator can easily read the relevant values.

[0030] Compared to placing the scale bar 231 on the worktable 11, the scale bar 231 and the indicator arrow 211 are located on the upper surface of the T-shaped guide rod 23 and the fixing plate 21, making them less susceptible to interference and wear. Furthermore, reading data is more convenient when adjusting the width of the wooden board. Because the scale bar 231 and the indicator arrow 211 are located on the upper surface of the T-shaped guide rod 23 and the fixing plate 21, they are less likely to be affected by external factors or experience wear. At the same time, when adjusting the width of the wooden board, it is more convenient and efficient for workers to read the relevant data. The L-shaped guide rod 24 is configured in the same way as the T-shaped guide rod 23, so it will not be described further.

[0031] Given that the two L-shaped guide rods 24 are symmetrically arranged around the T-shaped guide rod 23, the adjustment plate 22 can be moved and adjusted smoothly. At the same time, with the help of the readings of the six scale bars 231, the parallelism between the adjustment plate 22 and the cutting direction of the saw blade 12 can be more accurately guaranteed, thereby avoiding the situation where the long wooden board is deviated due to the deviation of the adjustment plate 22.

[0032] Locking studs 25 are located on the sides of both ends of the fixing plate 21 and are used to lock the L-shaped guide rod 24 to the fixing plate 21. Through holes 214 are provided on the sides of both ends of the fixing plate 21 for the locking studs 25 to extend into. The head of the locking stud 25 is designed in a butterfly shape for easy tightening.

[0033] Please see Figures 1 to 4 The clamping mechanism 30 is located on the side of the saw blade 12 away from the width adjustment structure, and is used to clamp the wooden board along the width direction onto the side of the adjustment plate 22 before cutting. The clamping mechanism 30 includes a moving plate 31, a fastening stud 32, a pressure plate 33, and a roller 34.

[0034] The movable plate 31 has through holes extending through its upper and lower surfaces, specifically located at both ends of the upper surface of the movable plate 31. The slots 111 of the worktable 11 are positioned corresponding to the through holes. The bottom end of the fastening stud 32 has a locking block 322 corresponding to the slot 111 (its structure is the same as the locking part 221 of the adjusting plate 22). The fastening stud 32 passes through the slot 111 and the through holes, with its stud portion extending out of the upper surface of the movable plate 31. The extended screw portion is equipped with a wing nut 321. Tightening the wing nut 321 can loosen or tighten the movable plate 31 and the worktable 11.

[0035] The pressure plate 33 is located between the moving plate 31 and the saw blade 12, and is elastically mounted on the moving plate 31. Specifically, the pressure plate 33 protrudes towards the moving plate 31 to form a guide post 331, the free end of which passes through the moving plate 31 and is provided with a pin 332. A spring is provided between the moving plate 31 and the pressure plate 33, and the spring is sleeved on the guide post 331. The surface of the pressure plate 33 facing the saw blade 12 has a mounting groove for mounting rollers 34. Along the cutting direction of the wood, multiple vertical rollers 34 are arranged in an array, and the curved surface of the rollers 34 partially protrudes from the surface of the pressure plate 33.

[0036] Furthermore, the pressure plate 33 and the adjusting plate 22 form outward-curving guide edges at the end where the wooden board enters, facilitating the board's entry. When the moving plate 31 is adjusted to the appropriate position, the pressure plate 33 applies pressure to the board under the action of the spring, ensuring a tight fit between the board and the adjusting plate 22. Simultaneously, the roller 34 reduces friction with the side of the board, facilitating its advancement.
