[0053] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0054] like Figures 1 to 3 As shown, an embodiment of the present invention provides a machine tool, which includes a processing assembly 1, a spindle assembly and a carrier 2. The processing assembly 1 includes a turntable portion 11 and a tailstock portion 12, the turntable portion 11 is arranged on one side of the tailstock portion 12 and is spaced apart from the tailstock portion 12; the rotating end of the turntable portion 11 is rotatably arranged. The spindle assembly is arranged on one side of the processing assembly 1; the processing assembly 1 is movably arranged in a direction close to or away from the spindle assembly. One side of the carrier 2 is connected to the rotating end of the turntable portion 11, and the other side is connected to the connecting end of the tailstock portion 12; the carrier 2 has a mounting surface 21 for mounting a jig 4; the mounting surface 21 is located between the turntable portion 11 and the tailstock portion 12, and the turntable portion 11 and the tailstock portion 12 are both spaced apart from the mounting surface 21 to avoid the jig 4.
[0055] The machine tool provided by the embodiment of the present invention avoids the interference problem between the jig 4 and the workbench when rotating in the traditional design by designing the turntable part 11 and the tailstock part 12 separately and setting them at intervals with the carrier 2, thereby allowing a larger rotation and processing of a wider range of workpiece sizes, and improving the flexibility and processing range of the machine tool when processing complex shapes and large diameter workpieces. The separate design of the turntable part 11 and the tailstock part 12 from the carrier 2, as well as the spacing between them and the mounting surface 21, avoids the unnecessary safety distance reserved in the originally limited working space to avoid interference, thereby more efficiently utilizing the space of the machine tool, increasing the processable area, and reducing the waste of travel. In addition, different types of jigs 4 can be installed on the mounting surface 21 of the carrier 2 without being subject to the structural restrictions of the turntable part 11 or the tailstock part 12, so that the machine tool can adapt to the processing requirements of a variety of workpieces, and improve the versatility of the equipment and the adaptability to different processing tasks. In this way, by avoiding structural interference, the risk of equipment damage caused by accidental collision is reduced, and the frequency of maintenance and repair is reduced, thereby reducing the operating cost of the machine tool and improving the availability and overall economy of the equipment. Therefore, the machine tool provided by this embodiment can solve the technical problem in the prior art that the fixture installed on the machine tool is prone to interfere with the workbench below the machine tool when rotating.
[0056] Specifically, the machine tool is a four-axis machine tool, the spindle of the spindle assembly can move along the extension direction from the turntable part 11 to the tailstock part 12 (the first axis direction, i.e., the X-axis), the spindle can be raised and lowered (the third axis direction, i.e., the Z-axis), the processing assembly 1 can be movably arranged in the direction close to or away from the spindle assembly (the second axis direction, i.e., the Y-axis), and the rotating end of the turntable part 11 can be rotatably arranged (the fourth axis direction, i.e., the A-axis).
[0057] Specifically, the turntable part 11 includes a first base 111 and a turntable part 112, and the turntable part 112 is located above the first base 111; the tailstock part 12 includes a second base 121 and a tailstock part 122, and the tailstock part 122 is located above the second base 121. Among them, the turntable part 112 is movably arranged on the first base 111 along the direction close to or away from the spindle assembly, and the tailstock part 122 is movably arranged on the second base 121 along the direction close to or away from the spindle assembly. With such a structural setting, the turntable part 112 and the tailstock part 122 can freely adjust their relative positions with the spindle assembly in the Y-axis direction, thereby increasing the processable range of the machine tool, while maintaining the stable support and precise positioning of the workpiece. This layered design enhances the processing flexibility of the machine tool and the adaptability of the workpiece size, especially when processing large or complex-shaped workpieces, it can effectively avoid structural interference, expand the processing range, and improve processing efficiency.
[0058] Specifically, the machine tool further includes a first driving member, which is arranged on the first base 111, and the driving end of the first driving member is movably arranged in a direction close to or away from the spindle assembly, and the driving end of the first driving member is drivingly connected to the turntable member 112. In this way, it is helpful to accurately position the turntable member 112 during the processing. The fine control ability of the first driving member ensures the stability and reliability of the turntable member 112 during the movement, thereby effectively improving the processing accuracy and the automatic operation level of the machine tool.
[0059] Specifically, the machine tool further includes a second driving member, which is disposed on the second base 121, and a driving end of the second driving member is movably disposed in a direction close to or away from the spindle assembly, and the driving end of the second driving member is drivingly connected to the tailstock member 122. In this way, the second driving member enables the tailstock member 122 to also move in a direction close to or away from the spindle assembly, and cooperates with the first driving member to achieve precise adjustment of the position of the tailstock member 122.
[0060] Specifically, the first driving member is a first servomotor, and the driving end of the first servomotor is connected to the turntable member 112 by a ball screw, and the second driving member is a second servomotor, and the driving end of the second servomotor is connected to the tailstock member 122 by a ball screw, so that the turntable member 112 and the tailstock member 122 move in the direction close to or away from the spindle assembly. In this way, the servomotor is used as the first driving member and the second driving member, and is connected to the turntable member 112 and the tailstock member 122 by a ball screw, so as to achieve high-precision positioning and stable power transmission. The closed-loop control characteristics of the servomotor enable the turntable member 112 and the tailstock member 122 to be accurately adjusted according to the control command when moving in the Y-axis direction, thereby avoiding interference with the spindle assembly and the fixture 4, and simultaneously ensuring the stability and repeatability of the processing process, further improving the processing accuracy and efficiency. The high efficiency and low friction characteristics of the ball screw also reduce energy loss and extend the service life of the drive system.
[0061] Specifically, the turntable 112 and the tailstock 122 are set to move synchronously. The synchronous movement setting ensures the coordination and consistency of the turntable 112 and the tailstock 122 when adjusting the position, avoiding unstable workpiece support or processing deviation caused by mismatched position adjustment. This synchronous movement mechanism can also optimize the processing flow, reduce the waiting time caused by component position adjustment, and improve the overall processing efficiency and production continuity.
[0062] Specifically, a first clamp 1121 is provided on the turntable part 112, and a second clamp 1221 arranged opposite to the first clamp 1121 is provided on the tailstock part 122. The first clamp 1121 and the second clamp 1221 are respectively used to fix the two sides of the carrier 2, the first clamp 1121 forms a rotating end, and the second clamp 1221 forms a connecting end; the clamping end of the first clamp 1121 and the clamping end of the second clamp 1221 can be movably arranged to move to a clamping position where the clamping end of the first clamp 1121 and the clamping end of the second clamp 1221 both clamp the carrier 2 or to an avoidance position where the clamping end of the first clamp 1121 and the clamping end of the second clamp 1221 both avoid each other with the carrier 2. The first clamp 1121 and the second clamp 1221 are both hydraulically driven clamps. With such a structural setting, the first clamp 1121 and the second clamp 1221 are set, so that the carrier 2 can be firmly fixed during the processing, which not only prevents the displacement of the workpiece during the processing, but also ensures the precise positioning of the workpiece, thereby improving the processing accuracy. The hydraulic drive mode of the clamp can provide a strong clamping force, and at the same time has the characteristics of fast response and precision control, and can adapt to workpieces of different sizes and weights, thereby improving the versatility and scope of application of the equipment. The hydraulic system also has an overload protection function, which can avoid damage to the workpiece or the fixture 4 due to excessive clamping force, thereby increasing the safety of machine tool operation.
[0063] Specifically, in order to facilitate the rotation of the rotating end, the connecting end of the tailstock portion 12 is rotatably disposed on the tailstock member 122 .
[0064] Specifically, the machine tool also includes a first oil circuit distributor 31, which is arranged on the turntable 112 and located on the side of the turntable 112 away from the carrier 2. The oil outlet of the first oil circuit distributor 31 is interconnected with the driving oil circuit of the first fixture 1121, and the opening of the oil outlet of the first oil circuit distributor 31 can be adjusted. The use of such a structural setting not only simplifies the layout of the hydraulic system, but also avoids the interference of the oil circuit on the processing area. The first oil circuit distributor 31 is interconnected with the driving oil circuit of the first fixture 1121, so that the first fixture 1121 can obtain stable hydraulic power to ensure the precise clamping of the carrier 2. At the same time, the adjustable opening design of the oil outlet of the first oil circuit distributor 31 facilitates the adjustment of the clamping force and improves the processing accuracy and safety.
[0065] Specifically, the machine tool also includes a second oil circuit distributor 32, which is arranged on the tailstock 122 and located on the side of the tailstock 122 away from the carrier 2, and the oil outlet of the second oil circuit distributor 32 is interconnected with the driving oil circuit of the second fixture 1221, and the opening of the oil outlet of the second oil circuit distributor 32 is adjustable. The use of such a structural setting ensures that the rationality of the oil circuit arrangement and the space for processing operations are not affected. Through the connection with the driving oil circuit of the second fixture 1221, the second oil circuit distributor 32 provides precise hydraulic control for the tailstock 12, ensuring the stable clamping and positioning of the tail end of the carrier 2. The adjustability of the opening of the oil outlet of the second oil circuit distributor 32 enables the machine tool to dynamically adjust the clamping force of the clamp according to actual processing requirements. This precise clamping force control also helps to improve processing accuracy and surface quality.
[0066] Specifically, the oil pressure of the oil outlet of the first oil circuit distributor 31 can be adjusted, and the oil outlet of the first oil circuit distributor 31 acts on the clamping end of the first clamp 1121, so that the clamping end of the first clamp 1121 can be driven to move by the oil pressure to achieve clamping or loosening.
[0067] Specifically, the oil pressure of the oil outlet of the second oil circuit distributor 32 can be set adjustably, and the oil outlet of the second oil circuit distributor 32 acts on the clamping end of the second clamp 1221, so that the clamping end of the second clamp 1221 can be driven to move by the oil pressure to achieve clamping or loosening.
[0068] Specifically, the machine tool also includes a first driving oil circuit, the inlet of the first driving oil circuit is connected to the oil outlet of the first oil circuit distributor 31, and the outlet of the first driving oil circuit is used to drive the clamping end of the first clamp 1121 to move.
[0069] Specifically, the machine tool also includes a second driving oil circuit, the inlet of the second driving oil circuit is connected to the oil outlet of the second oil circuit distributor 32, and the outlet of the second driving oil circuit is used to drive the clamping end of the second clamp 1221 to move.
[0070] In this embodiment, the turntable part 11 also includes a first lifting member 113, which is arranged on the first base 111, and the lifting end of the first lifting member 113 can be lifted and connected to the turntable part 112. The tailstock part 12 also includes a second lifting member 123, which is arranged on the second base 121, and the lifting end of the second lifting member 123 can be lifted and connected to the tailstock part 122. With such a structural arrangement, the addition of the first lifting member 113 and the second lifting member 123 provides the turntable part 11 and the tailstock part 12 with the ability to adjust in the vertical direction. This design allows the operator or the control system to dynamically adjust the height of the turntable part 112 and the tailstock part 122 according to the size and processing requirements of the fixture 4, ensuring the smooth rotation of the carrier 2. This is particularly beneficial for processing long-axis parts, special-shaped parts or workpieces that need to be processed from different heights. The ability to finely adjust the height can not only improve the processing accuracy, but also effectively enhance the adaptability and processing flexibility of the machine tool to various fixtures 4 and workpieces.
[0071] Specifically, the first lifting member 113 and the second lifting member 123 are arranged to move synchronously.
[0072] Specifically, the processing assembly 1 is arranged on and above the foundation to be installed, and the machine tool further comprises a distance detection member and a controller, wherein the detection end of the distance detection member is arranged on the installation surface 21 and is used to detect the distance between the installation surface 21 and the foundation to be installed in the height direction of the processing assembly 1. The first lifting member 113, the second lifting member 123 and the distance detection member are all connected to the controller to control the lifting of the first lifting member 113 and the second lifting member 123 according to the detection result of the distance detection member. With such a structural setting, by integrating the distance detection member on the installation surface 21 and connecting it to the controller, the machine tool realizes the automatic height adjustment function. The distance detection member can monitor the distance between the installation surface 21 and the foundation to be installed in real time, which helps to avoid equipment damage caused by height mismatch when processing the workpiece. The controller automatically adjusts the first lifting member 113 and the second lifting member 123 according to the detection result, realizes automatic compensation of height, improves the automation level of the processing process, reduces the need for manual intervention, improves the efficiency and accuracy of processing, and also reduces the processing defects caused by operating errors.
[0073] Specifically, when the distance detection component detects that the distance between the installation surface 21 and the base to be installed along the height direction of the processing component 1 is greater than the preset distance, the first lifting component 113 and the second lifting component 123 are controlled to remain in a stationary state; when the distance detection component detects that the distance between the installation surface 21 and the base to be installed along the height direction of the processing component 1 is less than or equal to the preset distance, the first lifting component 113 and the second lifting component 123 are controlled to rise to increase the distance between the installation surface 21 and the base to be installed along the height direction of the processing component 1.
[0074] In another embodiment, the turntable portion 11 further includes a first pad, which is detachably arranged on the first base 111, and the turntable member 112 is arranged on the first pad. The tailstock portion 12 further includes a second pad, which is detachably arranged on the second base 121, and the tailstock member 122 is arranged on the second pad. In this way, by using the detachable first pad and the second pad, the turntable portion 11 and the tailstock portion 12 obtain additional adjustment freedom. The design of the pad allows the operator to quickly replace pads of different heights or shapes according to the specific needs of the fixture 4, without complex mechanical adjustments or recalibration, to adapt to changing processing conditions. This modular design not only simplifies the adjustment process of the machine tool, but also improves the versatility and production efficiency of the equipment. Especially on production lines that require frequent changes in workpiece types or sizes, the design of detachable pads can significantly reduce adjustment time, reduce production costs, and enhance the production flexibility and rapid response capabilities of the machine tool.
[0075] In this embodiment, along the extension direction from the turntable part 11 to the tailstock part 12, the ratio of the maximum distance between the first base 111 and the second base 121 to the maximum length of the carrier 2 is greater than or equal to 0.7 and less than or equal to 1. With such a structural setting, by limiting the ratio of the maximum distance between the first base 111 and the second base 121 to the maximum length of the carrier 2 to between 0.7 and 1, it is ensured that the first base 111 and the second base 121 will not interfere with the fixture 4 on the mounting surface 21, and the mounting surface 21 can have sufficient length for mounting various fixtures 4. At the same time, the compactness of the structure and the processing range of the machine tool are taken into consideration, so that the machine tool can effectively utilize space while maintaining good processing performance, reduce the area occupied by the machine tool, and enhance its applicability and flexibility in a limited space.
[0076] In this embodiment, along the extension direction from the turntable member 112 to the first base 111, the minimum spacing between the bottom of the first base 111 and the mounting surface 21 is greater than or equal to 250 mm and less than or equal to 500 mm. Along the extension direction from the tailstock member 122 to the second base 121, the minimum spacing between the bottom of the second base 121 and the mounting surface 21 is greater than or equal to 250 mm and less than or equal to 500 mm. In this way, it is possible to ensure that the carrier 2 has a certain amount of space margin during the processing, avoid accidental contact with the base, and protect the carrier 2 and the base from damage. This design also takes into account the convenience of installation and removal of the fixture 4 and the workpiece, as well as the need for chip cleaning and safety distance that may be generated during the processing, thereby improving the safety and maintenance convenience of the machine tool in actual operation.
[0077] Specifically, the machine tool also includes a visual detection part, an alarm and a controller. The detection end of the visual detection part is arranged on one side of the carrier 2 and is used to detect the maximum distance between the side of the fixture 4 on the mounting surface 21 away from the mounting surface 21 and the mounting surface 21. The alarm is used to send an alarm signal; the alarm and the visual detection part are both connected to the controller, and the controller is used to control whether the alarm sends an alarm signal according to the detection result of the visual detection part. With such a structural setting, by integrating the visual detection part, the alarm and the controller, the machine tool realizes real-time monitoring of the position and state of the fixture 4, as well as timely warning of potential safety risks. The visual detection part can accurately detect the maximum distance between the fixture 4 and the mounting surface 21, ensuring the rationality and safety of the fixture 4 during installation and use. Based on the visual detection results, the controller automatically triggers the alarm to remind the operator to take timely measures, avoiding accidents caused by improper installation of the fixture 4, improving the safety and stability of the production process, and at the same time, due to timely warning and adjustment, it also avoids invalid operations in the processing process, improving production efficiency and the service life of the fixture 4.
[0078] Specifically, when the visual detection component detects that the maximum distance between the side of the jig 4 on the mounting surface 21 away from the mounting surface 21 and the mounting surface 21 is greater than the preset height distance, the controller controls the alarm to send an alarm signal to warn the operator to avoid the jig 4 being installed at too high a height, which may cause the jig 4 to interfere with the base to be installed during rotation, or control the first lifting component 113 and the second lifting component 123 to rise synchronously; when the visual detection component detects that the maximum distance between the side of the jig 4 on the mounting surface 21 away from the mounting surface 21 and the mounting surface 21 is greater than, less than or equal to the preset height distance, the controller controls the alarm not to send an alarm signal to ensure the safe and smooth progress of the processing operation.
[0079] Specifically, the machining component 1 is movably arranged along the extension direction of the machining component 1; or, the spindle of the spindle assembly is movably arranged along the extension direction of the machining component 1.
