Technical Field

[0001] This utility model relates to the field of turret technology, specifically a servo turret for turning. Background Technology

[0002] A power turret is a type of turret used in CNC machine tools, primarily used to mount various cutting tools such as lathe, milling, and drilling tools. A traditional power turret's power switching device consists of a power source, a rotating sleeve, a drive shaft, and a drive shaft sleeve; the power source is a servo motor, with a bevel gear fixed to its output shaft.

[0003] In the existing equipment, the sleeve is equipped with a bevel gear that meshes with the bevel gear on the output shaft of the power source, and the switching of different tools is completed by rotating the cutter head.

[0004] However, in actual use, although the above-mentioned equipment can perform tool switching, its rotational accuracy is not perfect, which makes it easy for deviations to occur when switching tools. In view of this, we propose a servo turret for turning. Utility Model Content

[0009] Preferably, the first bevel gear and the second bevel gear mesh with each other, and the center line of the output shaft and the center line of the second bevel gear are on the same straight line, so that the first bevel gear can smoothly drive the second bevel gear to move, and thus the second bevel gear can transmit the force to the assembled cutting tool through the output shaft when it rotates.

[0010] Preferably, the turret has several mounting slots, and these mounting slots are arranged in a circular array on the outer wall of the turret, so that the outer wall of the turret can be filled with multiple sets of cutting tools for use.

When the turret needs to be rotated, the piston assembly is activated to adjust the fixed gear plate, thereby rotating the turret. This allows for smooth control of the entire system, enabling the switching of different tools for cutting, ensuring cutting accuracy, and preventing deviations caused by vibration from reducing the cutting effect.

[0016] 2. The servo turret for turning machining, when the drive shaft pulley two drives the rotating spindle to rotate, will be further stabilized by setting angular contact ball bearings and thrust cylindrical roller bearings, and will be further stabilized by deep groove ball bearings one and two, ultimately improving the overall stability and practicality.

[0024] like Figures 1-6 As shown, this utility model provides a technical solution: a servo turret for turning, including a housing 1, a transmission box 2 disposed on the outer wall of the housing 1, a cover plate 3 detachably installed on the upper end of the housing 1, a protective sleeve 6 detachably installed on the outer wall of the housing 1, a sleeve rotatably installed on the inner wall of the transmission box 2, a turret 7 fixedly connected to the end of the sleeve, the protective sleeve 6 being sleeved on the outer side of the sleeve disposed between the turret 7 and the transmission box 2, a milling cutter switching and high-precision cutting running component 4 disposed on the outer wall of the transmission box 2, and a rotation mechanism for switching the position of the turret 7 disposed inside the transmission box 2.

[0025] Furthermore, a flange 411 is detachably installed on the outer wall of the housing 1, a protective sleeve 6 is fixedly connected to the outer wall of the housing 1, a piston assembly 413 is provided on the inner wall of the protective sleeve 6, an inner sleeve 421 is detachably installed on the inner wall of the protective sleeve 6, a power transmission shaft 416 is detachably installed on the inner wall of the inner sleeve 421, a bevel gear 417 is fixedly connected to the end of the rotating spindle 405, an output shaft 418 is rotatably installed on the inner wall of the inner sleeve 421, a bevel gear 419 is fixedly connected to the end of the output shaft 418, and a front cover 420 is detachably installed at the end of the inner sleeve 421. The center line of the protective sleeve 6, the center line of the inner sleeve 421, and the center line of the turret 7 are all on the same straight line, so that the turret 7 can rotate and move smoothly on the outer wall of the protective sleeve 6, thereby enabling the turret to withstand high-load machining cutting forces and achieve a repeatability accuracy of 0.0015mm, while realizing drilling and milling machining with a maximum diameter of 30mm during cutting.

[0026] In this embodiment of the utility model, bevel gear 1 417 and bevel gear 2 419 mesh with each other, and the center line of the output shaft 418 and the center line of bevel gear 2 419 are on the same straight line, so that bevel gear 1 417 can smoothly drive bevel gear 2 419 to move, and then when bevel gear 2 419 rotates, it can transmit the force to the assembled tool through the output shaft 418. The turret 7 has a number of mounting slots, and the number of mounting slots are arranged in a circumferential array on the outer wall of the turret 7, so that the outer wall of the turret 7 can be filled with multiple sets of tools for use.

[0027] Furthermore, the inner wall of the transmission box 2 is provided with a stabilizing component 5, which includes a deep groove ball bearing 501, which is detachably installed on the inner wall of the transmission box 2. The inner wall of the housing 1 is detachably installed with a deep groove ball bearing 502, an angular contact ball bearing 503, and a thrust cylindrical roller bearing 504. The thrust cylindrical roller bearing 504 is adapted to the rotating spindle 405, so that the rotating spindle 405 can transmit power smoothly. The turret 7 has several mounting slots, which are arranged in a circumferential array on the outer wall of the turret 7, so that the outer wall of the turret 7 can be filled with multiple sets of tools for use. In addition, the internal structure adopts a shock-absorbing design, which can effectively improve the surface accuracy of the machining.

[0028] Furthermore, the indexing assembly 8 includes an indexing motor 801, which is fixedly mounted on the outer wall of the transmission box 2. An indexing synchronous pulley 802 is fixedly mounted on the output end of the indexing motor 801. An indexing synchronous pulley 804 is connected to the indexing synchronous pulley 802 via an indexing synchronous belt 803. A primary transmission gear 805 is fixedly mounted on the coaxial axis of the indexing synchronous pulley 804. An indexing shaft 806 is rotatably connected to the inner wall of the transmission box 2. A primary driven gear 807 is fixedly mounted through the indexing shaft 806. A secondary driven gear 808 is fixedly mounted on the coaxial axis of the primary driven gear 807. An indexing gear disk 809 is fixedly mounted inside the protective sleeve 6. A secondary indexing shaft 810 is fixedly mounted on the coaxial axis of the indexing gear disk 809. The indexing gear disk 809 and the secondary driven gear 808 mesh to achieve indexing transmission.

[0029] Specifically, the piston assembly 413 moves along its axis under the action of hydraulic oil, thereby disengaging the locking end of the piston assembly 413. The indexing motor 801 drives the indexing gear plate 809 and the secondary indexing shaft 810 to rotate through the indexing synchronous pulley 802, the indexing synchronous belt 803, the indexing synchronous pulley 804, the first-stage driven gear 807, and the second-stage driven gear 808.

[0030] In this invention, during daily use, starting the spindle motor 401 causes the first drive shaft pulley 422 to rotate the synchronous belt 403, which in turn causes the second drive shaft pulley 402 to rotate the main shaft 405, thus achieving the effect of the output shaft 418 driving the mounted tool for rotary cutting. When it is necessary to rotate the turret 7, starting the piston assembly 413, in conjunction with the retractable bushing, causes the locking end of the piston assembly 413 to disengage from the locking of the primary drive gear 805. At this time, starting the indexing motor 801, in conjunction with the first indexing synchronous pulley 802 and the indexing synchronous belt 803, causes the second indexing synchronous pulley 804 to rotate, thereby enabling the primary drive gear 805 to drive the primary driven gear. Rotation of 807, in turn, in conjunction with the secondary driven gear 808, drives the indexing gear 809 and the secondary indexing shaft 810 to rotate. This causes the sleeve, which is mounted inside the transmission box 2 and connects to the turret 7, to rotate, thereby rotating the turret 7. This allows the milling cutter on the turret 7 to be smoothly controlled, enabling the switching of different tools for cutting. This ensures cutting accuracy and prevents deviations caused by vibration from reducing the cutting effect. Furthermore, the standard BMT turret interface design allows for the use of various standard power tool holders, enabling complex shape composite machining. The overall design allows for smooth control, enabling the switching of different tools for cutting, ensuring cutting accuracy and preventing deviations caused by vibration from reducing the cutting effect.

[0031] When the drive shaft pulley 402 drives the rotating main shaft 405 to rotate, the rotating main shaft 405 is further stabilized by setting angular contact ball bearing 503 and thrust cylindrical roller bearing 504, and the deep groove ball bearing 501 and deep groove ball bearing 502 further stabilize it, ultimately improving the overall stability and practicality.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
