Description

Technical Field

[0001] This utility model belongs to the field of metal processing technology, and relates to a guide head for a sawing machine tool, particularly a rotatable guide head for a sawing machine tool. Background Technology

[0002] A sawing machine is a machine tool that uses a metal saw blade as the cutting edge to cut materials. Because the saw blade cuts narrow kerfs and has high cutting efficiency, it consumes little energy and wastes little material. It is also a highly efficient cutting machine tool with significant energy and material saving effects. During operation, the rotating metal saw blade must be positioned correctly by the action of the guide head. The performance of the sawing guide head directly affects the sawing accuracy. Existing sawing guide heads all have a gap between two guide bodies, which plays the most basic positioning role for the saw blade. The saw blade is subjected to different cutting forces when facing different profiles, which will also cause different degrees of deviation. At the same time, the chips generated during the sawing process will also adhere to the saw blade, affecting the cutting quality.

[0003] A search revealed a Chinese patent document disclosing an air-blowing high-speed sawing guide head [Application No.: 202320050703.X; Publication No.: CN 219188871 U]. This air-blowing high-speed sawing guide head includes a guide head fixing seat, a fixing plate mounted on the guide head fixing seat, a connecting plate mounted on the fixing plate via a first connecting shaft, two limiting wheels mounted on the connecting plate via a second connecting shaft, a top block seat mounted on the fixing plate, a top pressure block mounted on the top block seat, two fixed saw clamping blocks mounted on the fixing plate, and a pneumatic connector located at one end of each fixed saw clamping block. Two U-shaped grooves are provided on one side of each fixed saw clamping block, with the two limiting wheels located within these grooves. Because the air-blowing high-speed sawing guide head has a pneumatic connector on the fixed saw clamping block, it can blow air onto the saw blade, cooling and removing chips. The top pressure block and limiting wheels limit the deviation of the saw blade.

[0004] Although the patent provides cooling and chip removal for the saw blade, and the top pressure block and limiting wheel can limit the blade's offset, it cannot limit the saw blade when it is not in use, thus preventing it from accidentally falling off or becoming loose. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a rotatable guide head for sawing machines. The technical problem this utility model aims to solve is: how to limit the saw blade when it is not in use, restrict the state of the saw blade, prevent accidental detachment or loosening, and adjust the offset state of the saw blade caused by pressure during cutting, thereby improving the sawing effect.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A rotatable guide head for a sawing machine includes a guide frame, a mounting bracket fixed on the guide frame, and a guide seat rotatably connected to the guide frame. The guide frame is provided with an adjustment component for controlling the rotation of the guide seat, and the mounting bracket is fixedly connected to the machine tool by bolts. The guide seat has a pre-connection groove, and a fixed seat is fixed on the guide seat. The fixed seat has a fixing groove, and a pair of clamping plates are provided in the fixing groove. The fixed seat is provided with a drive component for controlling the clamping action of the two clamping plates.

[0008] The working principle of this utility model is as follows: the saw blade can travel through the pre-joint groove and the fixed groove to guide the saw blade during sawing. Then, the control component drives the guide seat to rotate, so that the saw blade can be offset within a certain range. The autonomous angle offset can alleviate and adjust the offset state of the saw blade caused by pressure during the cutting process, thereby improving the sawing effect. In addition, when the saw blade is not in use, the drive component can control two clamping plates to clamp and fix the saw blade, limit the saw blade, and improve the safety of use.

[0009] The guide seat is cylindrical, and the control component includes a meshing rack fixed on the arc surface of the guide seat. A hydraulic push rod is fixed on the guide frame, and a drive rack is fixed at the output end of the hydraulic push rod. The drive rack meshes with the meshing rack.

[0010] With the above structure, the drive rack can be moved by a hydraulic push rod. After the drive rack moves, it will mesh with the meshing rack, causing the guide seat to rotate as a whole, thereby causing the saw blade to shift at an angle.

[0011] The drive assembly includes a drive rod rotatably connected to a fixed base, a pair of drive gears coaxially fixed to the drive rod, a pair of drive gears rotatably connected to the fixed base, toothed belts connecting the two drive gears rotatably to their corresponding drive gears rotatably, drive screws coaxially fixed to the two drive gears rotatably, and a pair of drive threaded sleeves slidably connected to the fixed base. The two drive threaded sleeves are threadedly connected to their corresponding drive screws and fixedly connected to their corresponding clamping plates.

[0012] With the above structure, the two drive gears can be rotated by the drive rod. The two drive gears can then drive the corresponding drive gears to rotate through the toothed belt. After the two drive gears rotate, they will drive the corresponding drive screw to rotate. After the drive screw rotates, it will drive the corresponding drive threaded sleeve to move, thereby driving the corresponding clamping plate to complete the clamping action.

[0013] The pre-connected groove is connected to the fixed groove, and the fixed base is equipped with an adjustment wheel, which is coaxially fixedly connected to the drive rod.

[0014] With the above structure, the drive lever can be rotated by the adjustment wheel, which facilitates operation and improves operational convenience and overall work efficiency.

[0015] The bottom of the fixing groove is provided with an installation groove, and a protective wear-resistant block is fixed in the installation groove.

[0016] By adopting the above structure, the wear-resistant protective block can prevent the saw blade from damaging the main structure of this utility model during the pressure sawing process.

[0017] Compared with existing technologies, the rotatable guide head of this sawing machine has the following advantages:

[0018] 1. The saw blade travels through the pre-groove and fixed groove to guide the saw blade during sawing. The control component drives the guide seat to rotate, thereby shifting the saw blade at an angle within a certain range. This autonomous angle shift alleviates and adjusts the saw blade's offset caused by pressure during cutting, thus improving the sawing effect.

[0019] 2. When the saw blade is not in use, the two clamping plates can be controlled by the drive assembly to clamp and fix the saw blade, limiting its movement and improving safety. Attached Figure Description

[0027] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0028] like Figures 1-6 As shown, a rotatable guide head for a sawing machine includes a guide frame 1, a mounting bracket 2 fixed on the guide frame 1, and a guide seat 3 rotatably connected to the guide frame 1. The guide frame 1 is provided with an adjustment component for controlling the rotation of the guide seat 3, and the mounting bracket 2 is fixedly connected to the machine tool by bolts. The guide seat 3 has a pre-connection groove 4, and a fixing seat 19 is fixed on the guide seat 3. The fixing seat 19 has a fixing groove 5, and a pair of clamping plates 6 are provided in the fixing groove 5. The fixing seat 19 is provided with a drive component for controlling the clamping action of the two clamping plates 6.

[0029] The saw blade can travel through the pre-joint groove 4 and the fixed groove 5 to guide the saw blade during sawing. Then, the control component drives the guide seat 3 to rotate, so that the saw blade can be offset within a certain range. The autonomous angle offset can alleviate and adjust the offset state of the saw blade caused by pressure during the cutting process, thereby improving the sawing effect. When the saw blade is not in use, the two clamping plates 6 can be controlled by the drive component to clamp and fix the saw blade, limit the saw blade and improve the safety of use.

[0030] The guide seat 3 is cylindrical. The control component includes a meshing rack 7 fixed on the arc surface of the guide seat 3. A hydraulic push rod 8 is fixed on the guide frame 1. A drive rack 9 is fixed at the output end of the hydraulic push rod 8. The drive rack 9 meshes with the meshing rack 7.

[0031] With the above structure, the drive rack 9 can be moved by the hydraulic push rod 8. After the drive rack 9 moves, it will mesh with the meshing rack 7, causing the meshing rack 7 to drive the guide seat 3 to rotate as a whole, thereby driving the saw blade to shift angle.

[0032] The drive assembly includes a drive rod 10 rotatably connected within a fixed base 19, a pair of drive gears 11 coaxially fixed to the drive rod 10, a pair of drive gears 12 rotatably connected within the fixed base 19, toothed belts 13 connecting the two drive gears 11 to their corresponding drive gears 12, drive screws 14 coaxially fixed to the two drive gears 12, and a pair of drive threaded sleeves 15 slidably connected within the fixed base 19. Both drive threaded sleeves 15 are threadedly connected to their corresponding drive screws 14, and both drive threaded sleeves 15 are fixedly connected to their corresponding clamping plates 6.

[0033] Using the above structure, the drive rod 10 can drive the two drive gears 11 to rotate. The two drive gears 11 then drive the corresponding drive gears 12 to rotate through the toothed belt 13. After the two drive gears 12 rotate, they will drive the corresponding drive screw 14 to rotate. After the drive screw 14 rotates, it will drive the corresponding drive threaded sleeve 15 to move, thereby driving the corresponding clamping plate 6 to complete the clamping action.

[0034] The pre-connected groove 4 is connected to the fixed groove 5, and the fixed base 19 is provided with an adjustment wheel 16, which is coaxially fixedly connected to the drive rod 10.

[0035] With the above structure, the drive rod 10 can be rotated by the adjustment wheel 16, which makes it convenient for personnel to operate and improves the ease of operation and overall work efficiency.

[0036] The bottom of the fixing groove 5 is provided with an installation groove 17, and a protective wear-resistant block 18 is fixed in the installation groove 17.

[0037] With the above structure, the wear-resistant protective block 18 can prevent the saw blade from damaging the main structure of this utility model during the pressure sawing process.

[0038] The working principle of this utility model is as follows: The saw blade travels through the pre-joint groove 4 and the fixed groove 5, guiding the saw blade during sawing. The hydraulic push rod 8 pushes the drive rack 9 to move. After the drive rack 9 moves, it meshes with the meshing rack 7, causing the meshing rack 7 to drive the guide seat 3 to rotate as a whole, thereby causing the saw blade to deflect at an angle. This autonomous angle deflection alleviates and adjusts the saw blade's deviation caused by pressure during cutting, thus improving the sawing effect. When the saw blade is not in use, the control wheel 16 can drive the drive rod 10 to rotate. The drive rod 10 drives two drive gears 11 to rotate. The two drive gears 11 then drive the corresponding drive gears 12 to rotate through the toothed belt 13. The rotation of the two drive gears 12 drives the corresponding drive screw 14 to rotate. The rotation of the drive screw 14 drives the corresponding drive threaded sleeve 15 to move, thereby causing the corresponding clamping plate 6 to complete the clamping action, limiting the saw blade and improving the safety of use.

[0039] In summary, by moving the saw blade through the pre-joint groove 4 and the fixed groove 5, the saw blade is guided during sawing. Then, the control component drives the guide seat 3 to rotate, thereby shifting the saw blade's angle within a certain range. This autonomous angle shift alleviates and adjusts the saw blade's offset caused by pressure during cutting, thus improving the sawing effect. Furthermore, when the saw blade is not in use, the drive component can control the two clamping plates 6 to clamp and fix the saw blade, limiting its movement and improving safety.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
