Description

Technical Field

[0001] The invention belongs to the technical field of numerically controlled machine tools, and in particular relates to a spinning turret for locking a turret main box. Background Art

[0002] The typical CNC lathe operation mode is to clamp various cutting tools on a set of turret devices. The turret device's rotation is controlled by a program, enabling rapid switching between tools, aligning the required tool with the workpiece, and performing various turning operations on the workpiece. Using this operation mode, milling, drilling, boring, tapping and other processing steps can be completed on a single CNC machine tool, with a high degree of automation, significantly shortening processing time and reducing production costs. In addition, the workpiece only needs to be clamped once, which helps improve processing accuracy.

[0003] Currently, tool changes in a turret device are usually achieved by a servo motor driving a gear set to rotate the turret device. When the tool is processing a workpiece, the turret device needs to be stationary to ensure processing accuracy. If the tool moves or shakes during processing, it will directly affect the accuracy of workpiece processing. However, due to the difficulty of aligning the gears and wheel grooves between the gear sets at the same time, it is difficult to ensure the consistency of the position and angle of the tool after each tool change by relying solely on the control of the servo motor. In addition, during long-term operation, wear will occur between the gear sets, which will affect the accuracy of the turret device's rotation, making it impossible for the CNC lathe operation to meet the workpiece processing requirements. The turret locking device in the existing technology is also unable to achieve complete locking of the turret device. Summary of the Invention

DETAILED DESCRIPTION

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] On the contrary, the present invention covers any alternatives, modifications, equivalents, and solutions that fall within the spirit and scope of the present invention as defined by the claims. Furthermore, to facilitate a better understanding of the present invention, certain specific details are described in detail below in the detailed description of the present invention. Those skilled in the art will be able to fully understand the present invention without these details.

[0026] It should be noted that when two elements are referred to as being "fixedly connected", the two elements may be directly connected or there may be an intermediate element. The terms "upper", "lower" and similar expressions used herein are for illustrative purposes only.

[0027] like Figure 1 and Figure 3 The spinning turret shown includes a turret main housing 1, and tools of multiple workstations are arranged on the outside of the turret main housing 1 along its own circumferential direction. A cavity 3 is opened in the turret main housing 1, and the cavity 3 is arranged in a cylindrical shape and an opening is provided at one end of the cavity 3. A turret main shaft 4 is arranged in the cavity 3 along the axial direction of the turret main housing 1, and the axis of the turret main shaft 4 coincides with the axis of the cavity 3. The turret main shaft 4 is located at one end of the opening of the cavity 3 and is connected to a driving mechanism 6 for driving the turret main housing 1 to rotate around the turret main shaft 4 through a fixed seat 5. The driving mechanism 6 is set as a servo motor that can control the rotation angle of the turret main housing 1. Through program control, it is ensured that each time the turret main housing 1 rotates a set angle, the position of the tool at each workstation relative to the workpiece can be adjusted.

[0028] like Figure 1 、 Figure 2and Figure 4 As shown, the spinning turret also includes a turret base 2 fixed to the machine frame and in contact with the bottom surface of the turret main housing 1. The other end of the cavity 3 is set as the bottom of the turret main housing 1. The bottom of the turret main housing 1 is provided with a through hole 1. The other end of the turret spindle 4 passes through through hole 1 and is fixedly connected to the turret base 2. A bearing 10 is provided between the turret spindle 4 and through hole 1 to facilitate the rotation of the turret spindle 4 relative to the turret base 2.

[0029] like Figure 4 As shown, the outer edge of the bottom of the turret main box 1 is provided with protrusions 28 along its circumference, and the outer edge of the turret base 2 is provided with grooves 29 corresponding to the protrusions 28 along its circumference. The protrusions 28 cooperate with the grooves 29. On the one hand, they can guide the rotation of the turret main box 1 on the turret base 2; on the other hand, they can play a role in sealing and dustproofing, and can effectively prevent the waste generated after the workpiece is processed from entering the inside of the turret main box 1 and the turret base 2. Since it is inconvenient to clean, it is easy to affect the use of the spinning turret.

[0030] like Figure 1 and Figure 4 As shown, when the tool is processing the workpiece, the turret main housing 1 needs to be locked and positioned to prevent the tool from moving relative to the workpiece as the turret main housing 1 rotates, affecting the final processing effect. In this embodiment, a driving mechanism 2 that slides along the axial direction of the turret main shaft 4 is also provided in the cavity 3. The driving mechanism 2 is connected to a locking member 7 for limiting the rotation of the turret main housing 1. A positioning hole 1 8 is provided on the turret base 2 along its own axial direction, and the positioning holes 1 8 are distributed in sequence along the circumference of the turret base 2. The equal parts of the positioning holes 1 8 correspond to the tools, and the locking member 7 corresponds to the positioning holes 1 8. A positioning hole 2 9 corresponding to the positioning hole 1 8 is provided at the bottom of the turret main housing 1, and the positioning hole 2 9 is connected to the cavity 3.

[0031] When drive mechanism 1 (6) drives turret main housing 1, rotating the tool required for machining until it faces the workpiece, drive mechanism 1 (6) pauses, and drive mechanism 2 (2) drives locking member 7, which is sequentially inserted into positioning hole 2 (9) and positioning hole 1 (8), thereby establishing a fixed connection between turret main housing 1 and turret base 2. Since turret base 2 is fixed to the machine frame and does not move, turret main housing 1 also remains locked. To ensure the locking effect of turret main housing 1, a detection switch 30 is provided within turret base 2 to detect whether locking member 7 is inserted into positioning hole 1 (8) and positioning hole 2 (9).

[0032] Since the tool stations on different spinning turrets are different, the number of positioning holes 8 is also different. Therefore, the number of positioning holes 8 can be set according to the needs of the actual processing station, such as 2, 3, 4, 5, 6...20. A larger number of positioning holes 8 can also be set, evenly distributed along the circumferential direction of the turret base 2, and the number of positioning holes 9 and locking pieces 7 are both set to be the same and corresponding to the positioning holes 8.

[0033] like Figure 1 、 Figure 4 and Figure 6 As shown, the second driving mechanism includes a cylinder 11 which is sleeved on the turret spindle 4. The cylinder 11 is provided with a through hole 2 for the turret spindle 4 to pass through. A piston 12 is provided in the oil chamber of the cylinder 11 and the piston 12 is fixedly connected to the turret spindle 4. The piston 12 divides the oil chamber into a first oil chamber 13 and a second oil chamber 14. The first oil chamber 13 is provided above the second oil chamber 14. The turret spindle 4 is provided with a first oil channel 15 and a second oil channel 16 along its own axial direction. The first oil channel 15 is connected to the first oil chamber 13, and the second oil channel 16 is connected to the second oil chamber 14. The locking member 7 is provided on an end face of the cylinder 11 opposite to the bottom of the turret main box 1. Since the turret spindle 4 is fixed to the turret base 2 and the piston 12 is fixed to the turret spindle 4, when the turret main housing 1 is rotating and does not need to be locked, the oil flows into the first oil chamber 13 through the first oil passage 15, and the second oil passage 16 discharges the oil in the second oil chamber 14, causing the oil cylinder 11 to move upward along the axial direction of the turret spindle 4, that is, toward the open end of the cavity 3, driving the locking member 7 away from the positioning hole 9 at the bottom of the turret main housing 1. ; When the turret main housing 1 stops rotating and needs to be locked, the oil continues to flow into the second oil chamber 14 through the second oil channel 16, and the first oil channel 15 discharges the oil in the first oil chamber 13, causing the oil cylinder 11 to move downward along the axial direction of the turret main shaft 4, that is, move toward the bottom of the turret main housing 1, driving the locking member 7 to be inserted into the positioning hole 2 9 and the positioning hole 1 8 in turn, and the bottom surface of the oil cylinder 11 will contact and fit with the inner surface of the bottom of the turret main housing 1, thereby increasing the locking force.

[0034] In order to prevent leakage of oil when the oil lever moves up and down, a seal 17 in contact with the turret spindle 4 is provided in the second through hole, and a seal 18 in contact with the inner wall of the oil chamber is provided on the outer edge of the piston 12.

[0035] In order to ensure that the locking piece 7 can be accurately inserted into the positioning hole 2 9 and the positioning hole 1 8, a guide rod 19 is further provided in the cavity 3 along the axial direction of the turret main shaft 4. One end of the guide rod 19 is fixedly connected to the cylinder 11, and a through hole 3 is provided on the fixing seat 5 for the other end of the guide rod 19 to pass through. A guide sleeve 20 that slides with the guide rod 19 is provided in the through hole 3. The guide rod 19 further guides the movement of the cylinder 11 to prevent the cylinder 11 from sliding on the turret main shaft 4 and generating synchronous rotation due to the rotation of the turret main box 1.

[0036] like Figure 1 、 Figure 4 and 5 As shown, due to the influence of factors such as the weight of the turret main case 1 itself, the outer surface of its bottom will always be in close contact with the turret base 2, exerting a gravity on the turret base 2, which makes it inconvenient for the turret main case 1 to rotate. Therefore, in this embodiment, an adjustment pad 21 is provided on the inner wall of the cavity 3 along its own circumference. The adjustment pad 21 is fixedly connected to the inner cavity 3 of the turret main case 1, and the adjustment pad 21 is provided above the cylinder 11. When the turret main case 1 rotates, the cylinder 11 moves upward to contact the adjustment pad 21 and exerts an upward force on the adjustment pad 21, thereby lifting the entire turret main case 1, ensuring that there is a distance of 1 mm between the bottom surface of the turret main case 1 and the turret base 2, and ensuring that the bottom of the turret main case 1 does not contact the turret base 2 when it rotates, so that no friction is generated, thereby reducing the load of the entire spinning turret.

[0037] In order to reduce the friction generated between the cylinder 11 and the adjustment pad 21 when the turret main housing 1 rotates, the outer edge of the cylinder 11 is provided with a mounting groove 1 corresponding to the adjustment pad 21 along its own circumferential direction, and a needle bearing 1 corresponding to the adjustment pad 21 is provided in the mounting groove 1. Since the transverse end face of the adjustment pad 21 is in contact with the needle bearing 1, the needle roller 1 22 in the needle bearing 1 is distributed in sequence along the radial direction of the cavity 3. When the turret main housing 1 rotates, the needle roller 1 22 can generate radial sliding support to ensure the rotation of the turret main housing 1 relative to the cylinder 11.

[0038] like Figure 1 、 Figure 3 and Figure 4As shown, the fixing base 5 is further provided with a through hole 4, into which a rotating shaft 23 connected to the output end of the drive mechanism 1 6 is inserted. A bearing 24 is disposed between the rotating shaft 23 and the through hole 4. A gear 25 is disposed on the outer surface of the end of the rotating shaft 23 away from the drive mechanism 1 6. An inner ring gear 26 is disposed along the inner wall of the cavity 3 along its circumference, meshing with the gear 25. The drive mechanism 1 6 drives the rotating shaft 23 to rotate, and the meshing transmission between the gear 25 and the inner ring gear 26 drives the rotation of the turret main housing 1. In this embodiment, the diameter of the inner ring gear 26 is larger than that of the rotating shaft 23. A speed reducer can also be added between the drive mechanism 1 6 and the rotating shaft 23 as needed.

[0039] like Figure 1 and Figure 5 As shown, in order to reduce the friction generated between the cylinder 11 and the inner wall of the cavity 3 when the turret main box 1 rotates, the outer edge of the cylinder 11 that contacts the inner wall of the cavity 3 is provided with a mounting groove 2 along its own circumferential direction, and a needle roller bearing 2 is provided in the mounting groove 2. The needle roller 27 in the needle roller bearing 2 is distributed in sequence along the axial direction of the cavity 3. The needle roller 27 can generate radial sliding support to ensure the rotation of the turret main box 1 relative to the cylinder 11.

[0040] The above describes the embodiments of the present invention in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments. A person skilled in the art may make several modifications and improvements without departing from the present invention, and these should also be considered to fall within the scope of protection of the present invention.
