Description

Technical Field

[0001] This utility model relates to the field of power turret technology, specifically a fast tool-changing power turret device. Background Technology

[0002] A power turret is a tool with its own power source that can independently provide the main motion and feed motion to the cutting tool, thereby completing machining processes such as milling, drilling, and drilling.

[0003] In existing power turrets, the power shaft drives the turret to rotate, enabling rapid tool changing by aligning different tool tips with the workpiece. During tool changing, the connecting block at the inner end of the power base rotates into the notch of the drive block connected to the internal servo motor. The servo motor then drives the drive block to rotate, which in turn drives the power shaft of the moving tool holder, thus driving the tool tip on the moving tool holder to rotate. However, during actual operation, the connecting block at the inner end of the moving tool holder wears down, resulting in poor contact between it and the drive block on the servo motor, which exacerbates damage. Furthermore, the lack of lubrication between the drive block and the connecting block further accelerates the damage. Therefore, we propose a rapid tool changing power turret device. Utility Model Content

[0004] The purpose of this invention is to provide a fast tool-changing power turret device, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fast tool changing power turret device, including a rotating disk, a fixed disk is provided in the inner cavity of the rotating disk, and a plurality of fixed tool holders and moving tool holders are detachably and fixedly installed on the outer wall of the rotating disk;

[0006] The outer wall of the rotating disk is detachably fixed with a cover plate by bolts. A servo motor is embedded in the outer wall of the fixed disk. A drive block is fixedly connected to the outer end of the drive shaft of the servo motor. A limit notch is formed on the outer wall of the drive block. The inner end of the moving tool holder's power shaft is inserted into the inner cavity of the rotating disk. A connecting block is connected to the inner end of the power shaft of the moving tool holder. A sliding groove is formed on the outer end of the connecting block. A bidirectional threaded rod is rotatably installed in the inner cavity of the sliding groove. One end of the bidirectional threaded rod movably passes through the connecting block and is fixedly connected to a rotating block. Adaptive threaded sliders are fitted on both sides of the outer wall of the bidirectional threaded rod. A limit block is fixedly connected to the outer wall of the threaded slider.

[0007] By adopting the above technical solution, the rotating disk enables rapid replacement of different moving tool holders and rotation of the fixed tool holder to the workpiece, allowing for the use of different cutting heads to process the workpiece. The tool holder can be changed quickly. Simultaneously, when the connecting block at the inner end of the moving tool holder rotates to the drive block, two limit blocks directly engage with the limit notch. A servo motor then drives the drive block to rotate, thereby driving the moving tool holder to rotate the corresponding cutting head. When the limit blocks wear out, rotating the bidirectional threaded rod adjusts the position of the two limit blocks, allowing them to fit against the inner wall of the limit notch at the outer end of the drive block. This adjusts the fit, ensuring a high degree of fit when the drive block rotates the limit blocks, thus reducing wear.

[0008] In a preferred embodiment of this utility model, a square block is fixed at one end of the connecting block, and a matching square groove is provided at the tail end of the moving knife holder. The square block is inserted into the square groove, a first magnet block is fixed at the inner end of the square block, and a second magnet block is fixed in the inner cavity of the square groove.

[0009] By adopting the above technical solution, the connecting block can be directly pulled out from the tail end of the moving tool holder, so that it can be quickly disassembled and replaced after the limit block is worn to a certain extent.

[0010] In a preferred embodiment of the present invention, a rotary joint is fixed in the middle of the outer wall of the cover plate, an oil supply pipe is fixedly connected to the outer end of the rotary joint, a conduit is fixed to the inner end of the rotary joint, an oil supply channel is opened on one side of the outer wall of the fixed plate, the oil supply channel extends to the outer peripheral wall of the fixed plate, and the outer end of the conduit is inserted into the oil supply channel.

[0011] By adopting the above technical solution, when the moving tool holder is rotated, lubricating grease is supplied into the guide tube through the oil supply pipe. The lubricating grease can be discharged along the oil supply channel and accumulate at the outlet of the oil supply channel. When the rotating moving tool holder passes through the lubricating grease, the grease can adhere to the limiting block. After the limiting block moves into the limiting notch, it can be lubricated by the grease, further reducing wear.

[0012] In a preferred embodiment of the present invention, a first power shaft is fixed to the back of the rotating disk, and a second power shaft is fixedly connected to the back of the fixed disk, with the second power shaft movably passing through the first power shaft.

[0013] By adopting the above technical solution, the first power shaft can drive the rotating disk to rotate, and the second power shaft can drive the fixed disk to rotate.

[0014] In a preferred embodiment of this utility model, the outer wall of the rotating block is provided with an internal hexagonal groove.

[0015] By adopting the above technical solution, the internal hexagonal groove makes it convenient to operate the bidirectional threaded rod rotation with the aid of tools.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] The present application provides a fast tool change power turret device that can drive two limit blocks to move closer or further apart by rotating a bidirectional threaded rod. After wear occurs, rotating the bidirectional threaded rod drives the two limit blocks to adjust their positions so that the two limit blocks can fit against the inner wall of the notch at the outer end of the drive block, thereby adjusting the fit and ensuring a high fit when the drive block drives the limit blocks to rotate, which helps to reduce wear.

[0018] By supplying lubricating grease into the guide tube through the oil supply pipe when the moving tool holder is rotated, the lubricating grease can be discharged along the oil supply channel and accumulate at the outlet of the oil supply channel. When the rotating moving tool holder passes through the lubricating grease, the grease can adhere to the limiting block. After the limiting block moves into the limiting notch, it can be lubricated by the grease, further reducing wear. Attached Figure Description

[0029] Please see Figure 1-4 This utility model provides a technical solution: a fast tool changing power turret device, including a rotating disk 1, a fixed disk 16 is provided in the inner cavity of the rotating disk 1, and a plurality of fixed tool holders 11 and moving tool holders 12 are detachably and fixedly installed on the outer wall of the rotating disk 1.

[0030] The outer wall of the rotating disk 1 is detachably fixed with a cover plate 15 by bolts. The outer wall of the fixed disk 16 is fitted with a servo motor 3. The outer end of the drive shaft of the servo motor 3 is fixedly connected to a drive block 31. The outer wall of the drive block 31 is provided with a limit notch 32. The inner end of the moving tool holder 12 is inserted into the inner cavity of the rotating disk 1. The inner end of the drive shaft of the moving tool holder 12 is connected to a connecting block 4. The outer end of the connecting block 4 is provided with a slide groove. The inner cavity of the slide groove is rotatably installed with a bidirectional threaded rod 44. One end of the bidirectional threaded rod 44 movably passes through the connecting block 4 and is fixedly connected to a rotating block. Both sides of the outer wall of the bidirectional threaded rod 44 are fitted with matching threaded sliders 45. The outer wall of the threaded sliders 45 is fixedly connected to a limit block 46.

[0031] In actual use, the rotating disk 1 allows for quick replacement of different moving tool holders 12 and fixed tool holders 11 at the workpiece, enabling the use of different cutting heads for machining. The tool holders are quick to change. Simultaneously, when the connecting block at the inner end of the moving tool holder 12 rotates to the drive block 31, the two limiting blocks 46 directly engage with the limiting notch 32. Then, the servo motor 3 drives the drive block 31 to rotate, thereby driving the moving tool holder 12 to rotate the corresponding cutting head. When the limiting blocks 46 wear down, the bidirectional threaded rod 44 rotates to adjust the position of the two limiting blocks 46, allowing them to fit against the inner wall of the limiting notch 32 at the outer end of the drive block 31. This adjusts the fit, ensuring a high degree of fit when the drive block 31 rotates the limiting blocks 46, thus reducing wear.

[0032] Furthermore, the outer wall of the rotating block is provided with an internal hexagonal groove, which makes it convenient to operate the bidirectional threaded rod 44 to rotate with the aid of tools.

[0033] Furthermore, a first power shaft 13 is fixed to the back of the rotating disk 1, and a second power shaft 14 is fixedly connected to the back of the fixed disk 16. The second power shaft 14 is movably inserted through the first power shaft 13. The first power shaft 13 can drive the rotating disk 1 to rotate, and the second power shaft 14 can drive the fixed disk 16 to rotate.

[0034] like Figure 1 and2 As shown in Figure 3; a square block 41 is fixed to one end of the connecting block 4, and a matching square groove is opened at the tail end of the moving tool holder 12. The square block 41 is inserted into the square groove, and a first magnet block 43 is fixed to the inner end of the square block 41. A second magnet block 42 is fixed to the inner cavity of the square groove, so that the connecting block 4 can be directly pulled out from the tail end of the moving tool holder 12, so that the limiting block 46 can be quickly disassembled and replaced after it is worn to a certain extent.

[0035] like Figure 1 and 2 As shown in Figure 4; a rotary joint 2 is fixed in the middle of the outer wall of the cover plate 15. The outer end of the rotary joint 2 is fixedly connected to the oil supply pipe 21. The inner end of the rotary joint 2 is fixed with the conduit 22. An oil supply channel 17 is opened on one side of the outer wall of the fixed plate 16. The oil supply channel 17 extends to the outer peripheral wall of the fixed plate 16. The outer end of the conduit 22 is inserted into the oil supply channel 17.

[0036] By supplying lubricating grease into the conduit 22 through the oil supply pipe 21 when the moving tool holder 12 is rotated, the lubricating grease can be discharged along the oil supply channel 17 and accumulate at the outlet of the oil supply channel 17. As the rotating moving tool holder 12 passes through the lubricating grease, the grease can adhere to the limiting block 46. After the limiting block 46 moves into the limiting notch 32, it can be lubricated with grease, further reducing wear.

[0037] The implementation principle of the rapid tool change power turret device of this application is as follows: In actual use, the rotating disk 1 rotates, thereby enabling rapid replacement of different moving tool holders 12 and the fixed tool holder 11 to rotate to the workpiece, so that different tool heads can be used to process the workpiece. The tool change is rapid. At the same time, when the connecting block at the inner end of the moving tool holder 12 rotates to the drive block 31, the two limit blocks 46 will directly engage in the limit notch 32. Then, the servo motor 3 drives the drive block 31 to rotate, thereby driving the moving tool holder 12 to drive the corresponding tool head to rotate. After the limit blocks 46 wear out, the bidirectional threaded rod 44 rotates to adjust the two limit blocks 46. The position of the limit blocks 46 allows them to fit against the inner wall of the limit notch 32 at the outer end of the drive block 31, thereby adjusting the fit and ensuring a high fit when the drive block 31 drives the limit blocks 46 to rotate. This helps reduce wear. When the moving tool holder 12 rotates, lubricating grease is supplied into the guide tube 22 through the oil supply pipe 21. The lubricating grease can then be discharged along the oil supply channel 17 and accumulate at the outlet of the oil supply channel 17. As the rotating moving tool holder 12 passes through the lubricating grease, the grease can adhere to the limit blocks 46. After the limit blocks 46 move into the limit notch 32, they can be lubricated with grease, further reducing wear.
