DETAILED DESCRIPTION

[0050] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0052] In this article, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0053] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0054] Reference Figure 1 to Figure 6, is an embodiment of the utility model, a horizontal CNC machine tool is proposed, which is used to detect the taper of a workpiece to be turned, including a detection frame 4, the detection frame 4 is slidably arranged relative to the workpiece, a rotating detection member 5 is rotatably arranged on the detection frame 4, a first contact 11 is swingably arranged at one end of the rotating detection member 5, and a second contact 12 is arranged at the other end of the rotating detection member 5. After the rotating detection member 5 is driven to slide, the first contact 11 and the second contact 12 are in contact with the workpiece in turn, and one end of the torsion spring 24 is arranged on the rotating detection member 5, and the other end is arranged on the first contact 11, providing a force for the first contact 11 to rotate.

[0055] In this embodiment, considering the complicated trend of the inclination of the stepped workpiece surface and the difficulty of accurately measuring and adjusting the tool angle in the prior art, this solution is designed with a detection frame 4, which is flexibly configured in the machine tool and can slide along the axis direction of the workpiece, ensuring the flexibility and adaptability of alignment and detection. The rotating detection member 5 is cleverly installed on the detection frame 4 and is designed as a rotating structure, which is a key component for realizing accurate taper measurement and angle. After the rotating detection member 5 is driven to move by the detection frame 4, the two ends of the rotating detection member 5 will abut against the end face and side face of the workpiece in turn. When one end abuts against the end face of the workpiece first, the rotating detection member 5 rotates, and the end abutting against the end face will be fixed to the edge of the end face of the workpiece until the other end of the rotating detection member 5 abuts against the side of the workpiece. At this time, the angle between the rotating detection member 5 and the axis of the workpiece is the taper angle of this taper processing. The first contact 11 and the second contact 12 are respectively fixed at the two ends of the rotating detection member 5. When the detection member 5 is driven close to the workpiece, the two contacts contact the workpiece in sequence, and directly sense the taper information through the physical contact point and the angle of the rotating detection member 5 during contact. The addition of the torsion spring 24 is another highlight. One end is fixed to the rotating detection member 5, and the other end is connected to the first contact 11. The tension of the torsion spring 24 ensures the stability of the first contact 11 when it contacts the workpiece, provides the necessary rebound force feedback, ensures the accuracy of the contact, and at the same time reduces vibration, thereby improving the accuracy of the measurement.

[0056] Furthermore, it includes a machine body 1, a rotating slide 2 that rotates relative to the machine body 1 and slides longitudinally, a tool holder 3 that slides and rotates relative to the rotating slide 2, and a detection frame 4 that is arranged on the tool holder 3. After the detection frame 4 is driven by the tool holder 3 to slide close to the workpiece, one end of the rotating detection member 5 is pushed to rotate by the workpiece, and after the rotation, the other end also abuts against the workpiece, so that both ends abut against the workpiece.

[0057] In this embodiment, a rotating slide 2 is designed, and the turning tool can be slidably arranged relative to the slide along the length direction of the rotating slide 2, so as to feed the turning tool arranged on the turning tool holder 3 along the taper direction of the workpiece surface. The detection frame 4 is set to be detachable. After the rotating detection member 5 detects the required rotation angle of the single rotating slide 2, the rotating slide 2 is rotated to the same angle as the rotating detection member 5 by the rotating driving device, and the taper turning can be achieved by the inclined feeding in the direction of the rotating slide 2. This design can quantify the surface taper of the step-type workpiece that is difficult to detect the taper. The angle of the rotating slide 2 is synchronously adjusted by using the rotating detection member 5 as the intermediate value. Since the angle of the rotating detection member 5 after the two ends of the rotating detection member 5 contact the workpiece is the best angle for one turning, it can be accurately measured according to the specific conditions of the turning process. After the taper turning at different stages, the detection and angle adjustment can be re-performed, so that the feeding of the turning tool can always fit the best taper turning position on the workpiece surface.

[0058] Furthermore, it also includes a first gear 6 rotatably set on the detection frame 4, and the rotating detection member 5 drives the first gear 6 to rotate after rotation, the second gear 7 is rotatably set relative to the body 1, the first gear 6 is meshed with the second gear 7, and the second gear 7 has a card slot 701, the rotating slide 2 has a first rotating shaft 201, the first rotating shaft 201 has a sliding groove 202 along the radial direction of the first rotating shaft 201, the sliding block 8 is slidably set in the sliding groove 202, and the sliding block 8 follows the first rotating shaft 201 to rotate to align with the card slot 701, and then is stuck in the card slot 701.

[0059] In this embodiment, the angle determination and transmission mechanism of the automatic angle swing device of the tool rest of the heavy-duty horizontal lathe is further optimized. The first gear 6 is arranged on the detection frame 4 and is directly connected to the rotating detection member 5. When the rotating detection member 5 slides with the tool rest 3 and contacts the workpiece and rotates, the first gear 6 rotates accordingly. The second gear 7 is a hollow gear ring. The second gear 7 has a slot 701, which cooperates with the first rotating shaft 201 of the rotating slide 2, so that the second gear 7 can achieve the effect of limiting the rotation of the rotating slide 2.

[0060] During specific operation, the rotating detection member 5 first rotates according to the shape and surface taper of the workpiece, and at the same time drives the first gear 6 and the second gear 7 to rotate. The size setting makes the rotating detection member 5 rotate at the same angle as the first gear 6 and the second gear 7. The position of the slot 701 on the second gear 7 also changes accordingly, and the sliding block 8 disengages from the slot 701. When the rotation angle of the rotating detection member 5 and the second gear 7 does not change, the rotating slide 2 is driven to rotate, so that the sliding block 8 re-clamps the sliding slot 701. At this time, the precise synchronous rotation angle adjustment of the rotating detection member 5 and the rotating slide 2 is achieved. Precise positioning locking is achieved to ensure the precise positioning of the tool rest. This design enhances the positioning accuracy of the automatic angle swing device of the lathe tool rest. Through the transmission and locking mechanism of the gears, stable and reliable tool rest position control is achieved, and the processing accuracy and automation level are optimized.

[0061] Furthermore, it also includes a longitudinal slide 9 slidably set on the machine body 1, one end of the detection frame 4 is set on the longitudinal slide 9, and the other end is set on the turning tool holder 3, the transverse slide 10 is slidably set on the longitudinal slide 9, and the second gear 7 is rotatably set on the transverse slide 10.

[0062] In this embodiment, the longitudinal slide 9 is slidably arranged on the machine body 1, providing a longitudinal moving platform for the detection frame 4 and the tool holder 3, increasing the adjustment range of the device, so that the tool holder can slide in a larger range to adapt to different workpiece requirements. One end of the detection frame 4 is arranged on the longitudinal slide 9, and the other end is connected to the tool holder 3. This design enables the detection frame 4 to not only slide with the tool holder 3, but also to be adjusted under the guidance of the longitudinal slide 9, realizing the multi-dimensional movement of the tool holder and improving the positioning accuracy. At the same time, since the axis of the tool and the workpiece is in a vertical state, a better turning effect can be achieved to prevent damage to the tool or the workpiece surface. In this solution, one end of the detection frame 4 is arranged on the tool holder 3, and the other end is arranged on the longitudinal slide 9. It can only control the rotation of the rotating slide 2 while the tool holder 3 does not rotate, and there is no need to readjust the angle of the tool holder 3 after adjustment, thereby improving the processing efficiency. The transverse slide 10 is arranged to slide on the longitudinal slide 9, introducing a second-level sliding mechanism. The transverse slide 10 enables the device to have a more complex adjustment capability, which can be independent of the longitudinal movement and adapt to more complex workpiece contours. The combination of the longitudinal slide 9 and the transverse slide 10 allows the tool rest to perform compound sliding, first longitudinally adjusting to a rough position, and then fine-tuning through the transverse slide 10. This design not only improves the adjustment range and flexibility of the tool rest, but also ensures the accuracy of the transmission, so that the device can more efficiently adapt to the processing accuracy of complex workpieces, and improves the accuracy and efficiency of automated processing.

[0063] Furthermore, the rotating detection member 5 has a strip guide groove 501, and also includes a slider 13 slidably set in the strip guide groove 501, the second rotating shaft 14 is rotatably set on the slider 13, and is rotatably set on the detection frame 4, one end of the first elastic member 15 acts on the inner wall of the strip guide groove close to the second contact 12, and the other end acts on the slider 13.

[0064] In this embodiment, considering that the first contact 11 of the rotating detection member 5 will gradually deviate with the movement of the detection frame 4 and the rotation of the rotating detection member 5, and will eventually get stuck on the end face edge of the detection member, in order to maintain the stability of the rotating detection member 5 and the stability of the transmission between the first gear 6 and the second gear 7, the rotating detection member 5 is set to pure rotation on the detection frame 4. After the first contact 11 is stuck on the end face edge of the workpiece, there is not enough sliding space on one side of the second contact 12, which is easy to cause the structure to get stuck. This solution is designed with a strip guide groove 501 to make the second rotating shaft 14 of the rotating detection member 5 slide in the strip guide groove 501. In order to optimize the structure and make its movement more stable and reasonable, a slider 13 and a first elastic member 15 are provided. The specific state of the slider 13 is set to a sleeve shaft, which can make the second rotating shaft 14 slide inside the slider 13 and can also ensure the working stability of the first elastic member 15. This design improves the control accuracy of the automatic swing angle device of the heavy lathe tool holder, optimizes the adjustment speed and stability of the rotating detection member 5 through precise guidance and dynamic adjustment mechanism, and improves the overall processing efficiency and accuracy.

[0065] Furthermore, the ratchet 16 is arranged on the second rotating shaft 14 , and the pawl 17 is arranged on the detection frame 4 , and the ratchet 16 is meshed with the pawl 17 .

[0066] In this embodiment, the position is locked by setting the ratchet 16 and the pawl 17 on the second rotating shaft 14 and the detection frame 4, ensuring that the position of the rotating detection member 5 after adjustment will not change due to external forces. Since the rotation of the rotating detection member 5 will eventually be connected in series to the second gear 7, the last second gear 7, which is a limiting device, will not change due to external forces after the final adjustment. The meshing design of the ratchet 16 and the pawl 17 greatly enhances the positioning stability and power transmission reliability of the device, and can maintain accuracy even under high load or dynamic adjustment, thereby improving the efficiency and accuracy of processing and ensuring high-quality processing of the workpiece.

[0067] Furthermore, a guide bevel 801 is provided on one side of the rotation direction of the sliding block 8 . After the second gear 7 and the first rotating shaft 201 rotate relative to each other, the guide bevel 801 enables the sliding block 8 to slide out of the slot 701 .

[0068] In this embodiment, the accurate sliding control and exit of the block is realized by the design of the guide bevel 801 of the sliding block 8 and the design of the second gear 7. During the angle detection process, when the rotating detection member 5 rotates, the second gear 7 rotates accordingly. The sliding block 8 on the side of the rotation direction of the second gear 7 has a guide bevel 801. In this rotation direction, the sliding block 8 can slide out of the slot 701. The straight edge on the sliding block 8 is opposite to the guide bevel 801. When the second gear 7 rotates to the final adjustment position, the rotating carriage 2 is driven to rotate, and the sliding block 8 is re-engaged in the slot 701. The sliding block 8 on the straight edge side will be stuck with the edge of the slot 701, and the angle adjustment of the rotating carriage 2 is stopped at a precise position. The design of the bevel of the block and the cooperation of the second gear 7 improve the control accuracy and stability of the block, making the entire adjustment smoother and smoother, and improving the work efficiency and processing accuracy.

[0069] Furthermore, it also includes a second elastic member 18 , one end of which is arranged on the inner wall of the slide groove 202 , and the other end of which acts on the sliding block 8 .

[0070] In this embodiment, when the sliding block 8 slides along the slide groove 202, one end of the second elastic member 18 is fixed to the wall of the slide groove 202, and the other end is connected to the sliding block 8. In this way, during the sliding process, the second elastic member 18 provides the necessary resilience, which not only ensures the smooth sliding of the sliding block 8, but also prevents excessive impact, reduces vibration, ensures the accuracy of positioning, protects the device, and improves the durability and service life of the entire system.

[0071] Furthermore, it also includes a first screw rod 19 rotatably set on the machine body 1, a first nut 20 set on the longitudinal slide 9, the first screw rod 19 drives the first nut 20 to slide after rotation, the second screw rod 21 is rotatably set on the rotating slide 2, the second nut 22 is slidably set on the rotating slide 2, the turning tool holder 3 is rotatably set on the rotating slide 2, and the second screw rod 21 drives the second nut 22 to slide after rotation.

[0072] In this embodiment, the rotation of the first screw 19 and the first nut 20 drives the longitudinal slide 9 to adjust the tool rest 3 in the longitudinal direction, and the combination of the second screw 21 and the second nut 22 further drives the rotating slide 2 to accurately determine the angle of the tool rest 3. Through these two levels of transmission, the tool rest 3 can be accurately adjusted in the longitudinal and transverse dimensions. This embodiment improves the precise positioning and operating accuracy of the automatic angle swing device of the heavy lathe tool rest through the precise transmission of the double screw-nut, meets the high requirements of complex workpieces, and improves the flexibility and efficiency of processing.

[0073] Furthermore, it also includes a rotating driving member arranged on the transverse slide 10 to drive the rotating slide 2 to rotate, one end of the transmission belt 23 is arranged on the second rotating shaft 14, and the other end is arranged on the rotating shaft of the first gear 6, and the rotating shafts of the second rotating shaft 14 and the first gear 6 have the same diameter.

[0074] In this embodiment, the rotating drive member is placed on the transverse slide 10. This design directly drives the rotation of the transverse slide 10, which enhances the initiative of control. Through the direct power input of the rotating drive member, the transverse slide 10 can respond quickly, thereby improving the adjustment speed of the tool holder. One end is fixed to the second rotating shaft 14, and the other end is meshed with the rotating shaft of the first gear 6, and the two shafts have the same diameter. This design ensures the synchronization of the transmission belt 23, and the transmission ratio is 1:1, that is, direct transmission, which ensures no loss of power and makes the angle of rotation of the rotating detection member 5 more accurate. Rapid and accurate positioning and synchronous adjustment of the tool holder are achieved, improving processing efficiency and quality.
