Description

Technical Field

[0001] This invention relates to the field of multifunctional machine tool technology, specifically to a multifunctional machine tool for processing metal products. Background Technology

[0002] Compared to traditional machine tools, CNC machine tools have a significant advantage in terms of automation. For some metal workpieces, grinding, drilling, and bending processes are often involved. Traditional CNC machine tools typically only have one or two automatic processing functions. Therefore, when grinding, drilling, and bending processes are required, multiple CNC machine tools are often needed to perform the processing. During the workpiece transfer process, clamping and unclamping not only consumes time but also increases the probability of workpiece damage from collisions, highlighting the shortcomings of traditional CNC machine tools.

[0003] When existing multi-functional machine tools perform radial hole machining on tubular metal workpieces, especially for thicker tubular workpieces, the depth of the radial hole after drilling is relatively large. Therefore, the workpiece after radial hole machining needs to be removed and re-clamped on another machine tool specifically designed for radial hole grinding and polishing. If the machine tool does not have a device for grinding the surface of the tubular workpiece, the workpiece needs to be removed again and ground on another machine tool. This machining method requires the use of three machine tools to complete radial hole machining, inner wall grinding and polishing, and outer surface grinding of the tubular workpiece. The entire operation requires multiple clamping of the workpiece, which is very time-consuming. Furthermore, after radial hole grinding and polishing, the radial hole needs to be repositioned so that the grinder on the machine tool can accurately enter the radial hole. Inaccurate positioning can easily lead to poor grinding results.

[0004] Therefore, in view of this, the present invention proposes a multi-functional machine tool for metal product processing to make up for and improve the deficiencies of the prior art. Summary of the Invention

Then, the drilling component drills holes in the tubular workpiece. After the drilling component is reset, the sliding component drives the grinding component to move to the outside of the drilled tubular metal workpiece. The controller first inflates the airbag, which drives the arc-shaped grinding disc on the grinding structure to approach and adhere to the outer wall of the tubular metal workpiece until the pressure sensor receives pressure. The controller then stops inflating the airbag and closes the solenoid valve on the fourth air pipe. The controller then repeatedly inflates and deflates the connecting pipe and the second air pipe, driving the grinding disc and the toothed plate to move back and forth. The grinding disc rotates and moves back and forth while the grinding head rotates and moves up and down in the hole, thus completing the drilling, outer wall grinding, and hole grinding of the tubular metal workpiece.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention. It should be noted that the structure and working principle of the above-mentioned machine tool body 101, clamping component 102, cutting and drilling component assembly 103, grinding component 104 and sliding component are existing technologies and will not be described in detail here.

[0020] Please refer to Figure 1 - Figure 10 As shown, a multi-functional machine tool for processing metal products is used to perform continuous drilling and grinding on metal workpieces. It includes: a machine tool body 101, a clamping component 102, a drilling component 103, and a grinding component 104. The clamping component 102 is fixed to one side of the upper end of the machine tool body 101. The drilling component 103 is fixed to the upper end of the machine tool body 101 and located on one side of the clamping component 102. The grinding component 104 is installed on the upper end of the machine tool body 101 through a sliding component. The grinding component 104 includes a horizontal plate 2. Vertical plates 1 are fixedly installed at both the front and rear ends of the horizontal plate 2. The vertical plates 1 are slidably connected to the machine tool body 101 through the sliding component. The sliding component is used to drive the grinding component 104 to move on the machine tool body 101.

[0021] Specifically, the metal tubular workpiece that needs to be drilled and ground is fixed to the upper end of the machine tool body 101 by the clamping component 102, and then the drilling component 103 performs the drilling operation on the tubular workpiece. Then the drilling component 103 is reset, and the sliding component drives the grinding component 104 to grind the drilled tubular workpiece.

[0022] Please refer to Figure 1 - Figure 10 As shown, a rotating shaft 3 is rotatably connected to the horizontal plate 2 via bearings. A drive structure is provided on one side of the rotating shaft 3. The drive structure is used to drive the rotating shaft 3 to rotate. The drive structure includes a gear ring 5, a motor 6, and a gear 7. The gear ring 5 is fixed on the outer wall of the end of the rotating shaft 3 away from the mounting box 4. The motor 6 is fixed to one side of the horizontal plate 2 via a motor fixing plate. The gear 7 is fixed on the output shaft of the motor 6, and the outer wall of the gear 7 is meshed with the outer wall of the gear ring 5. The mounting box 4 is fixedly installed on the end of the rotating shaft 3 away from the horizontal plate 2, and a cover plate 12 is installed on the end of the mounting box 4 away from the rotating shaft 3.

[0023] Specifically, motor 6 is connected to an external power supply. Motor 6 can drive gear 7 to rotate. When gear 7 rotates, it drives gear ring 5 to rotate. When gear ring 5 rotates, it drives shaft 3 to rotate on horizontal plate 2, thereby driving mounting box 4 and cover plate 12 to rotate on one side of horizontal plate 2. When mounting box 4 rotates, it will synchronously drive clamping structure and grinding structure to rotate. Clamping structure is used to attach grinding structure to the outer wall of tubular metal workpiece that needs to be ground. When mounting box 4 rotates, it drives grinding structure to complete the grinding of the outer wall of tubular metal workpiece.

[0024] The mounting box 4 contains several sets of clamping structures. A grinding structure is fixedly installed at the outer end of the clamping structure. The grinding structure is used to grind the outer wall of the metal workpiece. The clamping structure is used to drive the grinding structure to move, so that the grinding structure can grind the outer wall of tubular metal products of different diameters, making it more widely applicable.

[0025] The clamping structure includes an air tube 8 and an airbag 30. One end of the airbag 30 is fixed to the inner wall of the mounting box 4, and the other end of the airbag 30 is fixedly mounted with a mounting plate 31. A telescopic rod 32 is fixedly mounted between the mounting plate 31 and the inner wall of the mounting box 4 through a fixing block. One end of the telescopic rod 32 is fixed to the side wall of the mounting plate 31, and the other end is fixed to the inner wall of the mounting box 4 through a fixing block. A spring 33 is sleeved on the outer end of the telescopic rod 32. One end of the spring 33 is fixed to the fixing block, and the other end of the spring 33 is fixedly connected to the mounting plate 31. When the spring 33 is in a balanced state, no air is injected into the airbag 30. When air is injected into the airbag 30 and it expands, the spring 33 is in a stretched state. One end of the air tube 8 passes through the rotating shaft 3 and is inserted into the mounting box 4. It is rotatably connected to the rotating sleeve 14 via a sealed bearing. Several air tubes 44 are fixedly installed on the outer end of the rotating sleeve 14. A solenoid valve is fixedly installed on the outer wall of each air tube 44. The end of the air tube 44 away from the rotating sleeve 14 is fixedly connected to and communicates with the airbag 30. The air tube 8 is rotatably connected to the inner wall of the rotating shaft 3 via a bearing. The end of the air tube 8 away from the rotating sleeve 14 extends out of the outer side of the rotating shaft 3 and is rotatably connected to the rotating sleeve 9 via a sealed bearing. A connecting pipe 10 is fixedly installed on the side wall of one end of the rotating sleeve 9.

[0026] Specifically, the connecting pipe 10 is fixedly connected to the external air supply pipe. When the drive structure of the air pipe 8 drives the rotating shaft 3 to rotate, the rotating shaft 3 rotates at the outer end of the air pipe 8 through the bearing, while the air pipe 8 remains stationary. When the external air supply pipe is connected to the air source, gas is supplied to the rotating sleeve 9 through the connecting pipe 10. The gas enters the air pipe 8 through the rotating sleeve 9. If the solenoid valve on the air pipe 44 is opened, the gas enters the air bag 30 through the air pipe 44. After the air bag 30 is inflated, it expands outward and drives the grinding structure to move synchronously, thereby adjusting the distance between the grinding structures. This allows for the grinding of the outer wall of tubular metal workpieces of different diameters.

[0027] The grinding structure includes a movable plate 34, a guide rod 35, a slider 37, and a connecting pipe 38. The movable plate 34 is located on one side of the mounting plate 31, and a pressure sensor 43 is fixedly installed on the side of the movable plate 34 closest to the mounting plate 31. The pressure sensor 43 is electrically connected to a controller fixed on the machine tool body 101. One end of the guide rod 35 is fixed to the side wall of the mounting plate 31 away from the airbag 30. The other end of the guide rod 35 slides through the side wall of the movable plate 34 and is fixedly installed with a baffle. A spring 36 is sleeved on the outer wall of the guide rod 35. One end of the spring 36 is fixedly connected to the movable plate 34, and the other end is fixedly connected to the mounting plate 31. The movable plate 34 can move on one side of the mounting plate 31 by squeezing the spring 36, while the guide rod 35 slides on the side wall of the movable plate 34 to guide and limit the movable plate 34.

[0028] The slider 37 is fixedly installed at one end of the movable plate 34. A corresponding sliding hole 13 is provided on the cover plate 12. The end of the slider 37 away from the movable plate 34 slides through the sliding hole 13 and is fixedly connected to one end of the connecting tube 38. When the airbag 30 inflates, it drives the mounting plate 31 and the movable plate 34 to move. The movement of the movable plate 34 drives the slider 37 to move. The slider 37 slides within the sliding hole 13, moving synchronously with the connecting tube 38. A piston ring 39 is fixedly installed on the outer side of the end of the connecting tube 38 away from the slider 37. A spring 40 is fixedly installed. An air cylinder 41 is sleeved on the outer end of the connecting pipe 38. The outer end of the air cylinder 41 is closed. The inner wall of the outer end of the air cylinder 41 is fixedly connected to the outer end of the spring 40. The inner wall of the air cylinder 41 is slidably connected to the outer wall of the piston ring 39. The piston ring 39 seals the connection between the air cylinder 41 and the connecting pipe 38. The air cylinder 41 can slide on the outer end of the connecting pipe 38 by stretching the spring 40. An arc-shaped grinding disc 42 is fixedly installed on the outer wall of the air cylinder 41. The arc-shaped grinding disc 42 is easy to fit on the outer wall of the tubular metal workpiece.

[0029] The inner end of the slider 37 is hollow and communicates with the interior of the connecting pipe 38. The outer end of the slider 37 is fixedly installed with the air pipe 45, which communicates with the inner end of the slider 37. The end of the air pipe 45 away from the slider 37 is fixedly connected to the air pipe 44. Solenoid valves are fixedly installed on both the air pipe 45 and the air pipe 44. The solenoid valves are electrically connected to the controller on the machine tool body 101.

[0030] Specifically, when external gas enters the air pipe 44, after opening the solenoid valve on the air pipe 45, the gas can enter the slider 37 through the air pipe 45, then enter the connecting pipe 38 through the inside of the slider 37, and then enter the space between the connecting pipe 38 and the air cylinder 41 through the other end of the connecting pipe 38. As more gas enters, the air pressure increases, which will push the air cylinder 41 to move outward through the tension spring 40. When the air cylinder 41 moves, it will move the grinding disc 42 outward in sync. When the connecting pipe 10 is vented, the air cylinder 41 is reset under the reaction force of the spring 40. By repeatedly charging and decharging the connecting pipe 10, the air cylinder 41 moves back and forth with the grinding disc 42 at the outer end of the connecting pipe 38. The grinding disc 42 can not only rotate with the mounting box 4, but also move back and forth on the connecting pipe 38, which increases the grinding effect on the outer wall of the tubular metal workpiece.

[0031] A connecting tube 15 is rotatably connected inside the mounting box 4. One end of the connecting tube 15 extends out of the cover plate 12. The outer end of the connecting tube 15 is provided with a grinding hole structure, which is used to grind holes in metal workpieces. The grinding hole components include a piston ring 16, a spring 17, an air cylinder 18, and an air cylinder 25. The piston ring 16 and the spring 17 are both fixed to the outer wall of the end of the connecting tube 15 away from the rotating sleeve 24. One end of the air cylinder 18 is closed, and the other end is fitted with a sleeve. Connected to the outer end of the connecting pipe 15, the inner wall of the closed end of the air cylinder 18 is fixedly connected to the outer end of the spring 17, the inner wall of the air cylinder 18 is slidably connected to the outer wall of the piston ring 16, and the piston ring 16 seals the connection between the air cylinder 18 and the connecting pipe 15. The outer end of the air cylinder 18 is fixedly installed with a toothed plate 19 and a hose 20. The air cylinder 18 can slide on the outer end of the connecting pipe 15 by stretching the spring 17, and at the same time move the toothed plate 19 and the hose 20.

[0032] A round rod 21 is fixedly installed at the lower end of the second air pump 25. A sleeve 23 is rotatably sleeved on the outer end of the round rod 21. The inner wall of the sleeve 23 is fixedly connected to the outer wall of the bearing. The inner wall of the bearing is fixedly sleeved on the outer wall of the round rod 21, allowing the sleeve 23 to rotate in place on the outer wall of the round rod 21. The sleeve 23 is fixed to the outer wall of the first connecting pipe 15 by a support rod 24. A gear 22 is fixedly installed at the lower end of the round rod 21, which rotates and fixes the round rod 21, the second air pump 25, and the gear 22 in place. The outer wall of the gear 22 meshes with the outer wall of the toothed plate 19. The upper end of the hose 20 rotates through the gear 22 and the side wall of the round rod 21 and connects to the inner end of the second air pump 25. The length of the hose 20 is greater than the travel distance of the first air pump 18 when it moves. An inner end of the second air pump 25 is inserted with... The moving rod 26 has a piston ring 27 fixedly installed at its lower end. The outer wall of the piston ring 27 is slidably connected to the inner wall of the air cylinder 25. The piston ring 27 seals the connection between the air cylinder 25 and the moving rod 26. A return spring is fixedly installed between the bottom ends of the moving rod 26 and the air cylinder 25. A grinding head 28 is fixedly installed at the top end of the moving rod 26. A guide plate 29 is fixedly installed on the upper outer wall of the moving rod 26. A limit strip is provided on the inner wall of the guide plate 29. The limit strip is slidably connected to the outer wall of the air cylinder 25. An air pipe 11 is inserted into the air pipe 8. One end of the air pipe 11 passes through the middle side wall of the rotating sleeve 9 and is rotatably connected to the rotating sleeve 9 through a sealed bearing. The other end of the air pipe 11 is connected to and communicates with the connecting pipe 15.

[0033] Specifically, air pipe 2 11 is connected to an external air source and inflates the connecting pipe 1 15. The gas enters between the connecting pipe 1 15 and the air cylinder 1 18. The air cylinder 1 18 slides outward on the connecting pipe 1 15 through the tension spring 17. The gas enters between the air cylinder 2 25 and the moving rod 26 through the hose 20. The moving rod 26 moves the grinding head 28 upward through the tension return spring. The grinding head 28 is inserted into the hole drilled in the tubular metal workpiece to grind the hole.

[0034] It should be noted that when the air tube 11 is inflated, when the gas enters between the connecting tube 15 and the air cylinder 18, the air cylinder 18 can slide on the outer end of the connecting tube 15 via the tension spring 17, which will move the toothed plate 19 and the hose 20. The gear 22 moves on the toothed plate 19 and moves the air cylinder 25, the moving rod 26 and the grinding head 28 in place to complete the grinding of the hole.

[0035] Specifically, the metal tubular workpiece that needs to be drilled and ground is fixed to the upper end of the machine tool body 101 by the clamping component 102. Then, the drilling component 103 performs a drilling operation on the tubular workpiece. After that, the drilling component 103 is reset, and the sliding component drives the grinding component 104 to move to the outside of the drilled tubular metal workpiece. The controller first inflates the airbag 30, and the airbag 30 drives the arc-shaped grinding disc 42 on the grinding structure to approach and adhere to the outer wall of the tubular metal workpiece until the pressure sensor 43 receives pressure. The controller then stops inflating the airbag 30 and closes the solenoid valve on the air pipe 44. The controller then repeatedly inflates and deflates the connecting pipe 10 and the air pipe 11, driving the grinding disc 42 and the toothed plate 19 to move back and forth. The grinding disc 42 rotates and moves back and forth while the grinding head 28 rotates and moves up and down in the hole, thus completing the drilling, outer wall grinding, and hole grinding of the pipe pile metal workpiece.
