[0037] See also Figure 1-Figure 4 As shown, the load-bearing Y-axis slide saddle of the vertical spindle includes:

[0038] A Y-axis saddle 1 is fixedly connected to the workpiece spindle 2 and is used to adjust the position of the workpiece spindle 2 in the Y-axis direction. A first inclined surface 1111 and a second inclined surface 1112 are symmetrically arranged on both sides of the upper surface of the Y-axis saddle 1. The first inclined surface 1111 and the second inclined surface 1112 are arranged on both sides of a first plane 1113 and connected to the first plane 1113.

[0039] Among them, the Y-direction saddle 1 is a symmetrical structure, the symmetry axis of the Y-direction saddle 1 is parallel to the Y-axis direction, the horizontal height of the outer edge of the first inclined surface 1111 away from the first plane 1113 is lower than the horizontal height of the first plane 1113, and the horizontal height of the outer edge of the second inclined surface 1112 away from the first plane 1113 is lower than the horizontal height of the first plane 1113.

[0040] Specifically, the front side surface and the rear side surface of the Y-axis saddle 1 are relatively provided with a first side surface 1114 and a second side surface 1115, the first side surface 1114 is connected to the front side edge of the first inclined surface 1111, the front side edge of the second inclined surface 1112 and the front side edge of the first plane 1113, and the second side surface 1115 is connected to the rear side edge of the first inclined surface 1111, the rear side edge of the second inclined surface 1112 and the rear side edge of the first plane 1113.

[0041] During the processing, the iron chips generated can fall on the first inclined surface 1111 and the second inclined surface 1112 which are arranged opposite to each other on both sides of the upper surface of the Y-direction saddle 1. The iron chips generated by the processing can fall naturally under the action of gravity through the first inclined surface 1111 and the second inclined surface 1112, thereby preventing the iron chips from accumulating on the machine tool base and its surrounding areas, and at the same time preventing the iron chips from affecting the machining accuracy of the machine tool and the operation of the working spindle, thereby reducing the risk of machine tool failure caused by the iron chips.

[0042] In implementation, the inclination angles of the first inclined surface 1111 and the second inclined surface 1112 relatively arranged on both sides of the upper surface of the Y-axis saddle 1 are not specifically limited, as long as the iron filings generated during the processing can fall off the first inclined surface 1111 and the second inclined surface 1112 due to their own gravity, and no further details will be given here.

[0043] Specifically, a first sinking base 31 and a second sinking base 32 parallel to the bottom surface of the Y-direction saddle 1 are disposed on the side of the first inclined surface 1111 away from the first plane 1113, and a third sinking base 33 and a fourth sinking base 34 parallel to the bottom surface of the Y-direction saddle 1 are disposed on the side of the second inclined surface 1112 away from the first plane 1113; wherein, the first sinking base 31 and the third sinking base 33 are disposed close to the first side surface 1114, and the second sinking base 32 and the fourth sinking base 34 are disposed close to the second side surface 1115. Several counterweights are movably disposed on the first sinking base 31, the second sinking base 32, the third sinking base 33, and the fourth sinking base 34 to adjust the center of gravity of the Y-direction saddle 1.

[0044] When a workpiece with an irregular shape is placed on the working spindle 2, the Y-axis saddle 1 may tilt due to the offset of the center of gravity of the workpiece. At this time, the direction and degree of the offset of the center of gravity of the workpiece are determined by analyzing the force condition of the workpiece spindle 2, and then a number of counterweights are correspondingly arranged on the first sinking base 31, the second sinking base 32, the third sinking base 33, and the fourth sinking base 34 to keep the Y-axis saddle 1 stable, thereby avoiding processing errors caused by tilting and achieving higher precision after the workpiece is processed.

[0045] In practice, the size and placement of the counterweights are not limited, as long as they can prevent the Y-axis saddle 1 from tilting and keep the Y-axis saddle 1 in an optimal balance state, which will not be elaborated here.

[0046] Specifically, a vibration sensor 5 is provided at a lower position of the Y-axis saddle 1 away from the workpiece spindle 2 to detect vibration data of the Y-axis saddle 1 .

[0047] When processing irregularly shaped workpieces, the Y-axis saddle 1 may vibrate due to the center of gravity offset of the workpiece and the vibration of the machine tool. These vibrations will affect the processing accuracy and may also cause the surface quality of the workpiece to be processed to decrease. The vibration sensor 5 is set at the lower position of the Y-axis saddle 1 away from the workpiece spindle 2 to monitor the vibration data of the Y-axis saddle 1 during the processing in real time, and convert the vibration data into electrical signals and transmit them to the control system. The control system analyzes these vibration data and then determines whether the current processing state is stable. If the vibration amplitude of the current Y-axis saddle 1 exceeds the preset threshold, the control system will adjust the processing strategy, such as reducing the cutting speed, increasing the cutting depth, adjusting the feed rate, etc., so as to reduce the vibration amplitude of the Y-axis saddle 1 and avoid the influence of vibration on the processing accuracy, so that the workpiece can achieve higher accuracy after the processing is completed.

[0048] In practice, the position and quantity of the vibration sensor 5 are not limited, as long as the vibration data of the Y-axis saddle 1 in the current processing process can be monitored, which will not be elaborated here.

[0049] Specifically, the workpiece spindle 2 is connected to the Y-direction saddle 1 via a first connection portion 6 provided on the Y-direction saddle 1 , wherein the first connection portion 6 is located at the geometric center of the Y-direction saddle 1 .

[0050] Specifically, the Y-axis saddle 1 is slidably connected to the Y-axis first guide rail 71 through a first slider combination, and is slidably connected to the Y-axis second guide rail 72 through a second slider combination; wherein the guide rail directions of the Y-axis first guide rail 71 and the Y-axis second guide rail 72 are parallel to the Y-axis direction, are located on the front side of the machine tool base, and are symmetrically arranged on the lower parts of both sides of the Y-axis saddle 1; the first slider combination includes a first slider 81 and a second slider 82 along the Y-axis direction, and the second slider combination includes a third slider 83 and a fourth slider 84 along the Y-axis direction.

[0051] When the Y-direction saddle 1 needs to move, the Y-direction saddle 1 drives the first slider 81 and the second slider 82 to move forward and backward along the Y-direction first guide rail 71, and the Y-direction saddle 1 drives the third slider 83 and the fourth slider 84 to move forward and backward along the Y-direction second guide rail 72.

[0052] In implementation, the connection mode of the first slider 81, the second slider 82 and the first Y-direction guide rail 71, and the connection mode of the third slider 83, the fourth slider 84 and the second Y-direction guide rail 72 are not limited, as long as the first slider 81 and the second slider 82 can move forward and backward linearly along the first Y-direction guide rail 71. The third slider 83 and the fourth slider 84 can move forward and backward linearly along the second Y-direction guide rail 72, which will not be described in detail here.

[0053] In implementation, there is no limitation on the connection method between the Y-axis saddle 1 and the first slider combination and the second slider combination, as long as the first slider combination and the second slider combination can drive the Y-axis saddle 1 to move forward and backward in a straight line.

[0054] Specifically, a first guide rail clamp is provided between the first slider 81 and the second slider 82 , and a second guide rail clamp is provided between the third slider 83 and the fourth slider 84 .

[0055] When the Y-axis saddle 1 needs to stop or maintain the current position, the first guide rail clamp and the second guide rail clamp are quickly started, and the first guide rail clamp clamps the Y-axis first guide rail 71, and the second guide rail clamp clamps the Y-axis second guide rail 72 to lock the Y-axis saddle 1, ensuring that the Y-axis saddle 1 remains in the current position.

[0056] Specifically, a first chip removal opening 111 is provided at the outer edge of the first inclined surface 1111 of the machine tool base close to the Y-axis saddle 1, and a second chip removal opening 112 is provided at the outer edge of the second inclined surface 1112 of the machine tool base close to the Y-axis saddle 1; wherein the bottom of the first chip removal opening 111 and the bottom of the second chip removal opening 112 are interconnected for installing a chip conveyor 12.

[0057] After the iron chips generated during the machining process fall on the first inclined surface 1111 and the second inclined surface 1112 of the Y-axis saddle 1, under the action of their own gravity, the iron chips fall into the first chip removal port 111 through the first inclined surface 1111, and then fall into the second chip removal port 112 through the second inclined surface 1112, and then fall into the chip conveyor 12 installed at the bottom of the first chip removal port 111 and the bottom of the second chip removal port 112, thereby avoiding the accumulation of iron chips on the machine tool base and its surrounding areas, and at the same time avoiding the influence of iron chips on the machine tool machining accuracy and spindle operation, reducing the risk of machine tool failure due to iron chips.

[0058] In practice, the positions, sizes and inclination angles of the inclined surfaces of the first chip removal opening 111 and the second chip removal opening 112 are not specifically limited, as long as the iron chips generated during the processing can fall into the first chip removal opening 111 through the first inclined surface 1111, fall into the second chip removal opening 112 through the second inclined surface 1112, and fall into the chip conveyor 12 from the first chip removal opening 111 and the second chip removal opening 112. The size of the chip conveyor 12 is not limited, as long as it can catch the iron chips naturally falling from the first chip removal opening 111 and the second chip removal opening 112, which will not be described in detail here.

[0059] Specifically, the Y-axis saddle 1 is driven by a Y-axis screw rod 10, and the Y-axis screw rod 10 is driven by a Y-axis drive motor 9; wherein the Y-axis screw rod 10 is arranged on the inner side of the Y-axis first guide rail 71 and / or the Y-axis second guide rail 72, and is connected to the Y-axis saddle 1.

[0060] When the Y-axis saddle 1 needs to move, the Y-axis drive motor 9 that receives the movement signal starts to rotate, and transmits the rotational motion of the Y-axis drive motor 9 to the Y-axis lead screw 10 through the coupling. The thread on the Y-axis lead screw 10 engages with the Y-axis saddle 1, thereby driving the Y-axis saddle 1 to move forward and backward in a straight line.

[0061] In implementation, the position and quantity of the Y-axis screw rod 10 and the Y-axis drive motor 9 are not limited. As long as the Y-axis drive motor 9 can drive the Y-axis screw rod 10 and the Y-axis saddle 1 can be driven by the Y-axis screw rod 10, it will not be repeated here.

[0062] Specifically, a first displacement sensor and a second displacement sensor are respectively disposed on the first Y-direction guide rail 71 and the second Y-direction guide rail 72. The first displacement sensor and the second displacement sensor are used to measure the moving distance and position of the Y-direction saddle 1 on the first Y-direction guide rail 71 and the second Y-direction guide rail 72.

[0063] When the Y-axis saddle 1 moves on the Y-axis first guide rail 71 and the Y-axis second guide rail 72, the first displacement sensor and the second displacement sensor will sense the displacement change of the Y-axis saddle 1, and the displacement change includes the moving displacement and current position of the Y-axis saddle 1. This displacement change is converted into an electrical signal and transmitted to the control system. The control system ensures the positioning accuracy of the Y-axis saddle 1 by analyzing the displacement change of the Y-axis saddle 1.

[0064] In implementation, the connection method between the first displacement sensor and the first Y-direction guide rail 71, and the connection method between the second displacement sensor and the second Y-direction guide rail 72 are not specifically limited, as long as they can provide stable and accurate displacement change results of the Y-direction saddle 1, and they will not be repeated here.

[0065] Specifically, the first side surface 1114 of the Y-direction saddle 1 is provided with a first telescopic portion 41 for shielding the front upper portion of the first Y-direction guide rail 71 and the front upper portion of the second Y-direction guide rail 72, and the second side surface 1115 is provided with a second telescopic portion 42 for shielding the rear upper portion of the first Y-direction guide rail 71 and the rear upper portion of the second Y-direction guide rail 72.

[0066] When the Y-axis saddle 1 moves forward and backward in a straight line, the first telescopic part 41 and the second telescopic part 42 shrink and enter the interior of the Y-axis saddle 1 to avoid interference with the processing environment, thereby ensuring the smoothness and accuracy of the movement of the Y-axis saddle 1. When the Y-axis saddle 1 is fixed in position, the workpiece to be processed begins. At this time, the first telescopic part 41 and the second telescopic part 42 unfold to catch the broken iron chips that fall during the processing, thereby preventing the iron chips from accumulating on the machine tool base and its surrounding areas, and at the same time avoiding the influence of the iron chips on the machine tool processing accuracy and spindle operation, reducing the risk of machine tool failure caused by iron chips.

[0067] In practice, the length and size of the first telescopic portion 41 and the second telescopic portion 42 are not limited, as long as the first telescopic portion 41 and the second telescopic portion 42 are completely inside the Y-direction saddle 1 when in the retracted state. When in the expanded state, the first telescopic portion 41 and the second telescopic portion 42 can catch the iron chips dropped during the processing, which will not be described in detail here.

[0068] Working process and principle:

[0069] Before processing the irregularly shaped workpiece to be processed, the irregularly shaped workpiece to be processed is fixed on the workpiece spindle 2. At this time, due to the offset of the center of gravity of the workpiece to be processed, the Y-axis saddle 1 is tilted. If the center of gravity of the workpiece to be processed is offset to the right at this time, counterweights are placed on the first sinking base 31 and the second sinking base 32. The number of counterweights is determined based on the offset degree of the workpiece to be processed so that the Y-axis saddle 1 maintains an optimal balance state.

[0070] When the position of the Y-axis saddle 1 needs to be adjusted, the first telescopic part 41 and the second telescopic part 42 are retracted and enter the interior of the Y-axis saddle 1. At the same time, the control system sends a movement signal, and the Y-axis drive motor 9 that receives the movement signal starts to rotate, and the rotational movement of the Y-axis drive motor 9 is transmitted to the Y-axis screw rod 10 through the coupling. The thread on the Y-axis screw rod 10 engages with the Y-axis saddle 1, thereby driving the Y-axis saddle 1 to move forward and backward in a straight line. The Y-axis saddle 1 drives the first slider 81 and the second slider 82 to move forward and backward along the Y-axis first guide rail 71, and the Y-axis saddle 1 drives the third slider 83 and the fourth slider 84 to move forward and backward along the Y-axis second guide rail 72. During the entire forward and backward movement process, the Y-axis first guide rail 71 and the Y-axis second guide rail 72 provide a stable movement path and support for the Y-axis saddle 1.

[0071] When the Y-direction saddle 1 moves on the Y-direction first guide rail 71 and the Y-direction second guide rail 72, the first displacement sensor and the second displacement sensor sense the displacement change of the Y-direction saddle 1, and the displacement change includes the initial position of the Y-direction saddle 1 on the Y-direction first guide rail 71 and the Y-direction second guide rail 72 and the current position of the Y-direction saddle 1 on the Y-direction first guide rail 71 and the Y-direction second guide rail 72. The control system analyzes the displacement change of the Y-direction saddle 1 based on the initial position and the current position, and determines whether the current positioning of the Y-direction saddle 1 is accurate. When the positioning of the Y-direction saddle 1 is inaccurate, the position of the Y-direction saddle 1 is readjusted.

[0072] When the Y-direction slide 1 needs to stop or maintain the current position, the first guide rail clamp and the second guide rail clamp are quickly started, the first guide rail clamp clamps the Y-direction first guide rail 71, and the second guide rail clamp clamps the Y-direction second guide rail 72 to lock the Y-direction slide 1, ensuring that the Y-direction slide 1 remains in the current position. At this time, the first telescopic part 41 and the second telescopic part 42 are unfolded to catch the broken iron chips dropped during the processing.

[0073] When processing an irregularly shaped workpiece, the workpiece spindle 2 connected to the first connection portion 6 starts to rotate, and the Y-axis saddle 1 vibrates while the workpiece spindle 2 rotates. The vibration sensor 5 arranged at the lower part of the Y-axis saddle 1 away from the workpiece spindle 2 monitors the vibration data of the Y-axis saddle 1 in real time during the processing, and converts the vibration data into an electrical signal and transmits it to the control system. If the control system analyzes the vibration data and determines that the current vibration amplitude of the Y-axis saddle 1 exceeds the preset threshold, the cutting speed is reduced or the cutting depth is increased or the feed rate is adjusted to reduce the vibration amplitude of the Y-axis saddle 1 and ensure the stability of the processing process.

[0074] During the processing, the iron chips generated fall on the first inclined surface 1111, the second inclined surface 1112, the first telescopic part 41, and the second telescopic part 42 which are arranged opposite to each other on both sides of the upper surface of the Y-direction saddle 1. Under the condition of their own gravity, the iron chips fall into the first chip removal port 111 through the first inclined surface 1111 and then fall into the chip conveyor 12 installed at the bottom of the first chip removal port 111 and the bottom of the second chip removal port 112; the iron chips fall into the second chip removal port 112 through the second inclined surface 1112 and then fall into the chip conveyor 12 installed at the bottom of the first chip removal port 111 and the bottom of the second chip removal port 112; the iron chips that fall on the first telescopic part 41 and the second telescopic part 42 are cleaned up by workers when the first telescopic part 41 and the second telescopic part 42 need to be retracted.
