Description

Technical Field

[0001] This invention relates to the field of cutting lathe technology, specifically a cutting lathe for workpiece machining. Background Technology

[0002] A cutting lathe for machining is a specialized piece of equipment used for precise cutting and surface treatment of steel pipes, bulk metals, or non-metallic materials. Its core functions include high-speed cutting, surface grinding, and dimensional calibration. Traditional cutting lathes typically consist of a power spindle, a feed system, and a clamping device. Material separation is achieved through rotating cutting blades, and they are widely used in fields such as construction, machinery manufacturing, and pipe processing.

[0003] The protective systems of existing cutting lathes for machining generally suffer from poor adaptability and cumbersome operation. Most of these devices use fixed protective covers or baffles that require manual removal, making it impossible to dynamically adjust the protective range according to the size of the workpiece and the amount of debris. This results in redundant protection when machining small workpieces but insufficient protection when machining large workpieces. Therefore, a cutting lathe for machining workpieces is provided to solve the above-mentioned problems. Summary of the Invention

[0004] To address the aforementioned problems, the present invention provides a cutting lathe for machining workpieces, thereby solving the problems described above.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A cutting lathe for machining workpieces includes a support table. An auxiliary workpiece lateral cutting component is installed on the support table. Two first protective plates and two second protective plates are respectively provided around the support table to prevent cutting debris from splashing. The two second protective plates are slidably connected to the side of the support table. A protective driving component is also installed inside the support table, which drives the first protective plates to slide along the side of the support table.

[0006] Furthermore, the support platform includes a main platform body, an auxiliary clamping plate is attached to the top of the main platform body, and two positioning screws are threadedly connected to the top of the main platform body. The bottom of the two positioning screws is attached to the auxiliary clamping plate, and the main platform body positions the auxiliary clamping plate by the two positioning screws.

[0007] Furthermore, a splash-proof arc-shaped baffle is installed on the top of the main platform, and the splash-proof arc-shaped baffle is located above the cutting end of the cutting assembly.

[0008] Furthermore, the cutting assembly includes a first drive motor, a cutting blade, and pulleys. The first drive motor is installed at the bottom of the inner wall of the main platform. One side of the cutting blade is rotatably connected to the inner wall of the main platform, and the top end of the cutting blade penetrates and extends out of the main platform. The other side of the cutting blade is connected to a first rotating rod. The output shaft of the first drive motor and the same side of the first rotating rod are both equipped with transmission belts, and the two transmission belts are connected by pulleys.

[0009] Furthermore, the protective drive component includes a second drive motor, the output shaft of which is connected to a first bevel gear via a coupling, and two second bevel gears meshing on both sides of the top of the first bevel gear, with a second rotating rod connected to the side of each of the two second bevel gears away from the first bevel gear.

[0010] Furthermore, the protective drive component also includes two electric push rods, both of which are fixed to the inner wall of the main body. The top ends of the output shafts of the two electric push rods are connected to adjacent second rotating rods. The opposite ends of the two second rotating rods are engaged with third rotating rods, and the two third rotating rods are rotatably connected to the inner wall of the main body.

[0011] Furthermore, each of the two electric push rods has a rotating disk rotatably connected to one end facing away from the other, and each of the two rotating disks has a hinge rod hinged to it. The top ends of the two hinge rods are hinged to the center of the bottom of the adjacent first protective plate.

[0012] Furthermore, the first protective plate includes a main body, on which a limiting groove is formed, and the main body is slidably connected to the side wall of the main platform through the limiting groove.

[0013] Furthermore, two protective pads are installed on the side of the main board near the support platform, and connecting grooves are provided on both sides of the main board. The main board is slidably connected to two adjacent second protective plates through the connecting grooves on both sides.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This device achieves efficient cutting and grinding of steel pipes and block parts through the cooperation of the support platform and cutting components. The adjustable protection system composed of the first and second protective plates can flexibly adjust the protection range according to processing requirements. The one-button start function of the protective drive component, combined with the precise control of the electric push rod, makes the lifting and lowering operation of the protective plate more intelligent, effectively preventing debris from splashing while significantly reducing the complexity of operation.

[0015] 2. This device, through the synergistic action of the limiting slide groove and the connecting groove, ensures the stability of the protective structure by linking the movement of the first and second protective plates, while the replaceable design of the protective pads extends the service life of the equipment. The transmission belt and pulley structure of the cutting component, in conjunction with the inner wall support of the main table, provides a stable rotation base for the cutting blade, ensuring cutting accuracy. The entire device, through mechanical linkage and modular design, achieves full-process optimization from cutting to protection, improving processing efficiency and reducing maintenance costs.

[0022] Reference Figure 1-5 A cutting lathe for machining workpieces includes a support table 1, on which an auxiliary workpiece lateral cutting component 2 is installed. Two first protective plates 4 and two second protective plates 5 are respectively provided around the support table 1 to prevent cutting debris from splashing. The two second protective plates 5 are slidably connected to the side of the support table 1. A protective driving component 3 is also installed inside the support table 1, which drives the first protective plates 4 to slide along the side of the support table 1.

[0023] As an optimization solution, such as Figure 1-5 As shown, the support platform 1 includes a main platform body 11. An auxiliary clamping plate 13 is attached to the top of the main platform body 11. Two positioning screws 12 are threadedly connected to the top of the main platform body 11. The bottom of the two positioning screws 12 is attached to the auxiliary clamping plate 13. The main platform body 11 positions the auxiliary clamping plate 13 by the two positioning screws 12. An anti-splash arc baffle 14 is installed on the top of the main platform body 11. The anti-splash arc baffle 14 is located above the cutting end of the cutting assembly 2.

[0024] Specifically, the main body 11, as the main body, can use positioning screws 12 to fix the auxiliary clamping plate 13, or it can loosen the positioning screws 12 to limit the auxiliary clamping plate 13, so that the auxiliary clamping plate 13 can only move towards or away from the cutting blade 21, which is convenient for cooperating with the cutting assembly 2 to cut the workpiece.

[0025] As an optimization solution, such as Figure 1-5 As shown, the cutting assembly 2 includes a first drive motor 25, a cutting blade 21, and a pulley 23. The first drive motor 25 is installed at the bottom of the inner wall of the main platform 11. One side of the cutting blade 21 is rotatably connected to the inner wall of the main platform 11, and the top of the cutting blade 21 penetrates and extends out of the main platform 11. The other side of the cutting blade 21 is connected to a first rotating rod 22. The output shaft of the first drive motor 25 and the same side of the first rotating rod 22 are both equipped with transmission belts 24. The two transmission belts 24 are connected by the pulley 23.

[0026] Specifically, the first drive motor 25 drives the first rotating rod 22 to rotate via two transmission belts 24 and pulleys 23. The first rotating rod 22 drives the cutting blade 21 to rotate. In this structure, the side of the transmission belt 24 away from the first rotating rod 22 is rotatably connected to the inner wall of the main platform 11, and the side of the cutting blade 21 away from the first rotating rod 22 is also rotatably connected to the inner wall of the main platform 11, which can form a stable support. The part of the top of the cutting blade 21 exposed on the main platform 11 can be used as the cutting surface.

[0027] As an optimization solution, such as Figure 1-5 As shown, the protective drive component 3 includes a second drive motor 31. The output shaft of the second drive motor 31 is connected to a first bevel gear 32 via a coupling. Both sides of the top of the first bevel gear 32 are meshed with second bevel gears 33. The sides of the two second bevel gears 33 away from the first bevel gear 32 are connected to second rotating rods 34. The protective drive component 3 also includes two electric push rods 35. Both electric push rods 35 are fixed to the inner wall of the main platform 11. The top ends of the output shafts of both electric push rods 35 are connected to adjacent second rotating rods 34. The opposite ends of the two second rotating rods 34 are engaged with third rotating rods 36. Both third rotating rods 36 are rotatably connected to the inner wall of the main platform 11. The opposite ends of the two electric push rods 35 are rotatably connected to rotating disks 37. Both rotating disks 37 are hinged with hinge rods 38. The top ends of the two hinge rods 38 are hinged to the center position of the bottom of the adjacent first protective plate 4.

[0028] Specifically, the second drive motor 31 drives the second rotating rods 34 on both sides to rotate via the first bevel gear 32 and the second bevel gear 33. The second rotating rods 34 engage with the third rotating rod 36, and the second rotating rods 34 can drive the third rotating rod 36 to rotate. When the third rotating rod 36 rotates, the rotation of the rotating disk 37 will drive the hinge rod 38 to move, that is, drive the first protective plate 4 to rise or fall to adjust its position. When only one side of the first protective plate 4 needs to be activated, the electric push rod 35 on the other side can be activated to drive the corresponding first bevel gear 32 to rise, so that the second bevel gear 33 disengages from the corresponding first bevel gear 32. When returning to the original state, it can be re-engaged by simply moving downward. Because the third rotating rod 36 has multiple inclined grooves and the second rotating rod 34 is a corresponding longitudinal locking block, the engagement can be very smooth without any jamming.

[0029] As an optimization solution, such as Figure 1-5 As shown, the first protective plate 4 includes a main body 41, on which a limiting groove 42 is provided. The main body 41 is slidably connected to the side wall of the main platform 11 through the limiting groove 42. Two protective pads 43 are installed on the side of the main body 41 near the support platform 1. Connecting grooves 44 are provided on both sides of the main body 41. The main body 41 is slidably connected to two adjacent second protective plates 5 through the connecting grooves 44 on both sides.

[0030] Specifically, the motherboard body 41 slides with the main body 11 through the limiting slide groove 42 to improve stability. The addition of the second protective plate 5 makes the sliding even more stable. Alternatively, the connecting groove 44 can be changed to a frosted surface so that when the motherboard body 41 moves, the second protective plates 5 on both sides will move up and down synchronously. The protective pad 43 can replace the motherboard body 41 in contact with some spark-like debris, making it convenient for replacement and maintenance after a period of time.

[0031] The working principle and method of this device: S1. The device uses a support platform 1 and a cutting assembly 2 to perform cutting and grinding operations on steel pipes or other pipe bodies and block parts in machining. It also incorporates a first protective plate 4 and a second protective plate 5 to form a four-sided protection to prevent debris from flying out. Since the two first protective plates 4 are located in front of and behind the cutting direction of the cutting assembly 2, they can be activated with one button by the protective drive component 3. The protective drive component 3 can be used to move the first protective plate 4 on either side. The two second protective plates 5 can be selected to leave only the first protective plate 4 for protection, depending on actual needs. If there are many debris and the parts being processed are small, the addition of the second protective plate 5 can increase the protective effect and the stability of the first protective plate 4, achieving a better protective effect.

[0032] S2. Inside the support platform 1, the main platform body 11 serves as the main body. The auxiliary clamping plate 13 can be fixed by the positioning screw 12, or the positioning screw 12 can be loosened to limit the auxiliary clamping plate 13, so that the auxiliary clamping plate 13 can only move towards or away from the cutting blade 21, which is convenient for cooperating with the cutting assembly 2 to cut the workpiece.

[0033] S3. Inside the cutting assembly 2, the first drive motor 25 drives the first rotating rod 22 to rotate via two transmission belts 24 and pulleys 23. The first rotating rod 22 drives the cutting blade 21 to rotate. In this structure, the side of the transmission belt 24 away from the first rotating rod 22 is rotatably connected to the inner wall of the main platform 11, and the side of the cutting blade 21 away from the first rotating rod 22 is also rotatably connected to the inner wall of the main platform 11, which can form a stable support. The part of the top of the cutting blade 21 exposed on the main platform 11 can be used as the cutting surface.

[0034] S4. Inside the protective drive component 3, the second drive motor 31 drives the second rotating rods 34 on both sides to rotate via the first bevel gear 32 and the second bevel gear 33. The second rotating rods 34 engage with the third rotating rod 36. The second rotating rods 34 can drive the third rotating rod 36 to rotate. When the third rotating rod 36 rotates, the rotation of the rotating disk 37 will drive the hinge rod 38 to move, that is, drive the first protective plate 4 to rise or fall to adjust its position. When only one side of the first protective plate 4 needs to be activated, the electric push rod 35 on the other side can be activated to drive the corresponding first bevel gear 32 to rise, so that the second bevel gear 33 disengages from the corresponding first bevel gear 32. When returning to the original state, it can be re-engaged by simply moving downward. Because the third rotating rod 36 has multiple inclined grooves and the second rotating rod 34 is a corresponding longitudinal locking block, it can be smoothly engaged without any jamming.

[0035] S5. Inside the first protective plate 4, the main board body 41 will slide with the main body 11 through the limiting slide groove 42 to improve stability. After the addition of the second protective plate 5, the sliding can be more stable. Alternatively, the connecting groove 44 can be changed to a frosted surface so that when the main board body 41 moves, the second protective plates 5 on both sides will move up and down synchronously. The protective pad 43 can replace the main board body 41 in contact with some spark-like debris, making it convenient for replacement and maintenance after a period of time.
