[0047] See also Figures 1 to 12 As shown, according to an embodiment of the present application, a vertical compound grinding machine is provided, which includes a base component 10 , a grinding component 20 and a supporting component 30 .

[0048] The base component 10 includes a base 11, a beam 12 and a workbench 13. The workbench 13 is arranged on the base 11. The beam 12 is arranged on the base 11 and is located on the outer peripheral side of the workbench 13, and the beam 12 extends along the X direction; the grinding component 20 includes a saddle 21, a slide 22, a static pressure turntable 26 and a grinding assembly 23.

The static pressure turntable 26 is installed on the slide 22 and can rotate in the XZ plane. The grinding assembly 23 is installed on the static pressure turntable 26 and is located above the workbench 13; the grinding assembly 23 includes a static pressure spindle 231, a first pipe The first tube body 232 and the second tube body 233, the hydrostatic spindle 231 is rotatably mounted on the hydrostatic turntable 26, one end of the first tube body 232 is vertically fixed to the center of the hydrostatic turntable 26, the second tube body 233 is connected to the first tube body 232 and is coaxially arranged with the first tube body 232, the second tube body 233 can rotate relative to the first tube body 232 around its own axis, the first tube body 232 and the second tube body 233 are provided with mutually connected liquid flow channels, and the liquid flow channels are connected with the liquid channel on the hydrostatic spindle 231 through a pipeline; the support component 30 is fixedly connected to the slide 22 and extends in the Y direction to the front of the table of the hydrostatic turntable 26, and the second tube body 233 is rotatably mounted on the support component 30. It should be noted that the liquid flow channels in this embodiment include hydraulic oil flow channels and coolant flow channels, etc., and correspondingly, the pipelines include hydraulic oil pipelines and coolant pipelines, etc.

[0049] When the vertical compound grinding machine in this embodiment is used to grind the workpiece, the workpiece is placed on the workbench 13, and then the saddle 21 is driven to move along the length direction of the crossbeam 12, that is, the X direction, and the slide plate 22, the hydrostatic turntable 26 and the grinding assembly 23 installed on the saddle 21 are driven to move synchronously, and at the same time, the slide plate 22 is controlled to move along the Z direction according to the processing needs to adjust the relative position relationship between the grinding assembly 23 and the workpiece. In addition, the grinding assembly 23 is installed on the hydrostatic turntable 26, and when the hydrostatic turntable 26 rotates in the XZ plane, it can drive the grinding assembly 23 to rotate to a certain angle, and cooperate with the rotation of the workbench 13 to grind the workpiece installed on the workbench 13.

[0050] In this embodiment, the first tube body 232 and the second tube body 233 are provided with mutually connected liquid flow channels, which are connected to the liquid channel on the static pressure main shaft 231 through a pipe. When the static pressure turntable 26 rotates, the static pressure main shaft 231 and the first tube body 232 can rotate synchronously with the static pressure turntable 26, and the second tube body 233 can rotate relative to the first tube body 232. At this time, when a pipe is provided in the space outside the first tube body 232 and the second tube body 233, the rotation of the second tube body 233 can drive the pipe connected to one side of the second tube body 233 to move. For example, when the first tube body 232 rotates clockwise, the second tube body 233 can also rotate synchronously clockwise, thereby avoiding entanglement of the pipe. The internal connection method of the first tube body 232 and the second tube body 233 is consistent with the rotating connection device in patent document 202311790494.3, and is no longer described in detail in this application.

[0051] In addition, in the present application, the vertical compound grinder is also provided with a supporting component 30, which is fixedly connected to the slide 22 and can extend in the Y direction in front of the table surface of the static pressure turntable 26. During actual installation, the second tube body 233 is rotatably installed on the supporting component 30. Through the action of the supporting component 30, the second tube body 233 can be stably supported in front of the static pressure turntable 26. The second tube body 233 is not easily pulled or torn due to the large number of pipes outside the second tube body 233. The structure is stable and can increase the service life of the vertical compound grinder of the present application.

[0052] Specifically, the support component 30 in this embodiment includes a support frame 31, and the support frame 31 is provided with an escape space 311 for avoiding the static pressure main shaft 231. When the static pressure turntable 26 drives the static pressure main shaft 231 to rotate, the setting of the escape space 311 can prevent the support frame 31 from interfering with the static pressure main shaft 231. Optionally, the support frame 31 in this embodiment can be a U-shaped or C-shaped structure, and the hollow part of the U-shaped or C-shaped structure forms the above-mentioned escape space 311, which has a simple structure and is easy to implement. In actual production, the support frame 31 in this embodiment can be fixed to the slide 22 by screws, buckles, welding, etc. As long as it is other deformation methods under the conception of this application, they are all within the protection scope of this application.

[0053] Furthermore, in this embodiment, a pipe joint 80 is provided at the end of the second tube body 233 close to the support frame 31, and a pipeline (not shown in the figure) is provided in the support frame 31, and the pipeline is connected to the pipe joint 80 for conveying liquid. In this embodiment, by providing a pipeline in the support frame 31 and connecting the pipeline to the pipe joint 80, such a configuration can not only disperse the pipelines on the outer peripheral side of the first tube body 232 and the second tube body 233, and avoid interference between the pipelines when the static pressure turntable 26 rotates; it can also optimize the layout of the pipeline, avoid exposing the pipeline to the external environment, and thus reduce the risk of the pipeline being damaged by the external structure.

[0054] Optionally, in an unillustrated embodiment of the present application, in order to prevent the pipe joint 80 from rotating and twisting the pipeline arranged in the support frame 31 when the second tube body 233 rotates, a rotatable third tube body (not shown in the figure) can be arranged at one end of the second tube body 233 close to the support frame 31, and the internal flow channel of the third tube body can be adaptively connected to the interior of the second tube body 233 (that is, to ensure that the corresponding conveying channel can flow the corresponding fluid), and then the pipe joint 80 can be connected to the third tube body.

[0055] Furthermore, the support frame 31 of the present application is provided with a cavity 312, an opening 313 and a cover plate 314, the opening 313 is connected to the cavity 312 and is directly opposite to one end of the second tube body 233 close to the support frame 31, the cover plate 314 is detachably arranged at the opening 313, and the pipe joint 80 is located in the cavity 312. In this embodiment, by installing the pipe joint 80 in the cavity 312, the pipe joint 80 can be prevented from being exposed to the external environment. In addition, the opening 313 is arranged at the position where the support frame 31 is directly opposite to the second tube body 233, which is convenient for the assembly and maintenance of the pipeline. At the same time, the support frame 31 is equipped with a cover plate 314 to cover the opening 313. When assembly and maintenance are required, the cover plate 314 is removed; when assembly and maintenance are not required, the cover plate 314 is covered. Optionally, the cover plate 314 in this embodiment can be fixed to the support frame 31 by screws, pins, etc.

[0056] Furthermore, the vertical compound grinding machine in this embodiment also includes an online detection component 40 and a controller (not shown in the figure), the online detection component 40 includes a detection component 41 and a standard block 42, the online detection component 40 is arranged on the slide 22, the standard block 42 is installed on the base 11 and is located on the outer peripheral side of the workbench 13, the detection component 41 moves with the slide 22 and cooperates with the standard block 42 to determine the movement error of the slide 22; the controller is electrically connected to the detection component 41 and controls the first motor 251 according to the signal transmitted by the detection component 41.

[0057] In this embodiment, the driving assembly 25 includes a screw mechanism 252 and a first motor 251. The saddle 21 is movably mounted on the screw mechanism 252. When the first motor 251 drives the screw mechanism 252 to rotate, the saddle 21 can be driven to move along the length direction of the screw mechanism 252, that is, the X direction. In this process, due to the influence of the thread structure on the screw in the screw mechanism 252, accumulated errors are easily generated during the movement of the saddle 21. In the present application, the vertical compound grinding machine is provided with an online detection assembly 41, and the detection assembly 41 of the online detection assembly 41 is mounted on the slide 22. When the saddle 21 moves, the detection assembly 41 can move synchronously along the X direction, and the standard block 42 of the online detection component 40 is arranged on the base 11. In actual use, the accumulated errors generated during the movement of the saddle 21 and the slide 22 along the X direction can be determined by the detection component 41 and the standard block 42. After that, the controller can control the first motor 251 according to the signal transmitted by the detection component 41, thereby compensating for the accumulated errors generated during the movement of the saddle 21 and the slide 22 along the X direction by the screw mechanism 252, thereby ensuring the processing accuracy of the workpiece by the grinding component 23 installed on the slide 22.

[0058] It is understandable that when the slide 22 moves along the Z direction on the saddle 21, accumulated errors will also be generated. In this embodiment, by installing the detection component 41 on the slide 22, the detection component 41 and the standard block 42 cooperate with the corresponding detection method, and the accumulated errors of the slide 22 moving along the Z direction can also be detected and compensated. That is to say, in this embodiment, by reasonably installing the position of the online detection component 40, the online detection component 40 can detect the accumulated errors of the slide 22 in the X and Z directions, and can cooperate with the controller to timely calibrate the accumulated errors in the movement of the slide 22, which can improve the processing accuracy of the grinding component 23 on the workpiece in this embodiment.

[0059] Combination Figures 1 to 3 , Figure 6 and Figure 7As shown in the figure, a detection groove 421 is provided on the standard block 42 of this embodiment. The detection assembly 41 includes a mounting bracket 411, a detection rod 413 and a detection head 414. The mounting bracket 411 is fixed to the slide 22; one end of the detection rod 413 is rotatably mounted on the mounting bracket 411, and the other end of the detection rod 413 is provided with a detection head 414. The detection rod 413 has a detection position (such as rotation relative to the mounting bracket 411) to drive the detection head 414 to insert into the detection groove 421. Figure 2 and rotate relative to the mounting bracket 411 to a avoidance position (as shown) set against the side of the slide 22 Figure 3 As shown), and the detection head 414 is electrically connected to the controller.

[0060] In this embodiment, since the detection rod 413 is rotatably mounted on the mounting bracket 411, when it is necessary to use the online detection component 40 to detect the accumulated movement errors of the saddle 21, the slide 22, etc., it is only necessary to rotate the detection rod 413 relative to the mounting bracket 411 and drive the detection head 414 to insert into the detection groove 421 for measurement, and compare the measured value with the actual control value to obtain the error value, and then feed the error value back to the controller, and the controller can control the movement of the saddle 21, the slide 22, etc. according to the error value to compensate for the error. When the online detection component 40 is not used, it is only necessary to rotate the detection rod 413 relative to the mounting bracket 411 to the side of the slide 22 and be in an avoidance position. In this way, it is possible to prevent the detection rod 413 from interfering with other objects during the operation of the grinding assembly 23, and the structure is stable and reliable.

[0061] Furthermore, the detection groove 421 in this embodiment is arranged through the standard block 42 along the Y direction, and the first end of the detection rod 413 is connected to the mounting bracket 411 through a rotating shaft (not shown in the figure), and the axis of the rotating shaft extends along the X direction. With such an arrangement, when the detection rod 413 rotates around the X direction to switch between the detection position and the avoidance position, it is more suitable for the detection head 414 to be inserted into the detection groove 421 or rotated out of the detection groove 421, and will not interfere with the standard block 42, which is more suitable for automatic control.

[0062] Furthermore, the detection component 41 in this embodiment also includes a rotating motor 412, which is mounted on the mounting bracket 411 and is connected to the rotating shaft drive, and the rotating motor 412 is electrically connected to the controller. In this embodiment, by setting the rotating motor 412 and making the rotating motor 412 electrically connected to the controller, when it is necessary to detect the accumulated error generated by the operation of the vertical composite grinder, it is only necessary to send a control instruction to the controller, and the controller can control the saddle 21 and the slide 22 to move to the initial position, and at the same time, the rotating motor 412 can be controlled to drive the rotating shaft to drive the detection rod 413 to rotate and switch to the detection position. After the detection rod 413 has completed the detection and sent a control signal of the detection result to the controller, the controller can drive the rotating motor 412 to drive the rotating shaft to drive the detection rod 413 to rotate and switch to the avoidance position, which has a simple structure and is easy to control.

[0063] Of course, in other embodiments of the present application, the rotating motor 412 may not be provided, and the detection rod 413 may be hinged on the mounting bracket 411. In this way, when in use, the detection rod 413 can be driven to rotate and switch between the detection position and the avoidance position by applying external force to the detection rod 413. As long as it is other deformation methods based on the conception of the present application, they are all within the protection scope of the present application.

[0064] In order to drive the slide 22 to move along the Z direction relative to the slide saddle 21, the grinding component 20 in this embodiment also includes a linear rail 24 and a second motor (not shown in the figure), wherein the linear rail 24 is fixedly arranged on the slide saddle 21 and extends along the Z direction, the slide 22 is installed on the linear rail 24 and can move along the length direction of the linear rail 24, and the second motor is connected to the slide 22 to drive the slide 22 to move along the linear rail 24. During actual driving, a transmission mechanism such as a lead screw assembly can also be arranged between the second motor and the slide 22. In the actual working process, the displacement of the slide 22 along the Z direction will also produce accumulated errors. For this reason, the detection head 414 in this embodiment includes a lateral detection part 4141 and a vertical detection part 4142, the lateral detection part 4141 is used to detect the distance between the detection head 414 and the side wall of the detection groove 421, and the vertical detection part 4142 is used to detect the distance between the detection head 414 and the groove bottom surface 4213 of the detection groove 421; and the controller also controls the second motor according to the signal transmitted by the detection component 41. By detecting the distance between the detection head 414 and the side wall of the detection groove 421 through the lateral detection unit 4141, the accumulated error of the saddle 21 and the slide 22 along the X direction can be determined; through the action of the vertical detection unit 4142, the accumulated error of the slide 22 along the Z direction can be determined.

[0065] Exemplarily, the lateral detection unit 4141 and the vertical detection unit 4142 in this embodiment can be distance sensors, or proximity switches or laser displacement sensors, etc. As long as they are other structural components that can detect distance, they are within the protection scope of this application.
