[0052] Specifically, the support component 30 in the embodiment includes a support frame 31, which is provided with a clearance space 311 for avoiding the static pressure spindle 231. When the static pressure turntable 26 drives the static pressure spindle 231 to rotate, the clearance space 311 can prevent the support frame 31 from interfering with the static pressure spindle 231.

[0053] Further, the second pipe body 233 in the embodiment is provided with a pipe joint 80 at the end close to the support frame 31, and the support frame 31 is provided with a pipeline (not shown in the figure) connected with the pipe joint 80 for conveying liquid. In the embodiment, by arranging the pipeline in the support frame 31 and connecting the pipeline with the pipe joint 80, such arrangement can not only disperse the pipes on the outer circumferential side of the first pipe body 232 and the second pipe body 233 to avoid interference between the pipes when the static pressure turntable 26 rotates, but also optimize the arrangement mode of the pipeline to avoid the pipeline being exposed to the external environment, thereby reducing the risk of damage to the pipeline by external structures.

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

Optionally, the cover plate 314 in the embodiment can be fixed on the support frame 31 by means of screws, pins, and the like.

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

[0057] In the embodiment, the driving assembly 25 comprises a screw mechanism 252 and a first motor 251, the slide saddle 21 is movably installed on the screw mechanism 252, when the first motor 251 drives the screw mechanism 252 to rotate, the slide saddle 21 can be driven to move along the length direction of the screw mechanism 252, i.e. the X direction. In this process, due to the influence of the screw structure on the screw rod in the screw mechanism 252, accumulated error is prone to occur in the movement of the slide saddle 21. In the present application, the vertical compound grinding machine is provided with the online detection component 41, the detection assembly 41 of the online detection component 41 is installed on the slide plate 22, when the slide 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, through the cooperative detection of the detection assembly 41 and the standard block 42, the accumulated error generated in the movement of the slide saddle 21 and the slide plate 22 along the X direction can be determined, and then the controller can control the first motor 251 according to the signal transmitted by the detection assembly 41, so as to compensate the accumulated error generated in the movement of the slide saddle 21 and the slide plate 22 along the X direction driven by the screw mechanism 252, thereby ensuring the machining precision of the grinding assembly 23 installed on the slide plate 22 to the workpiece.

[0058] It can be understood that when the slide plate 22 moves along the Z direction on the slide saddle 21, accumulated error will also be generated, in the embodiment, the detection assembly 41 is installed on the slide plate 22, and the detection assembly 41 cooperates with the standard block 42 in a corresponding detection mode, so as to detect and compensate the accumulated error generated in the movement of the slide plate 22 along the Z direction. That is to say, in the embodiment, the position of the online detection component 40 is reasonably installed, so that the online detection component 40 can detect the accumulated error of the slide plate 22 in the X and Z directions, the accumulated error in the movement of the slide plate 22 can be timely calibrated by the controller, and the machining precision of the grinding assembly 23 in the embodiment to the workpiece can be improved.

[0059] In combination with Figures 1 to 3 , Figure 6 and Figure 7The standard block 42 in the embodiment is provided with a detection groove 421. The detection assembly 41 comprises a mounting bracket 411, a detection rod 413 and a detection head 414. The mounting bracket 411 is fixed to the slide plate 22. One end of the detection rod 413 is rotatably connected to the mounting bracket 411. The other end of the detection rod 413 is provided with the detection head 414. The detection rod 413 is capable of rotating relative to the mounting bracket 411 to drive the detection head 414 to insert into the detection groove 421 (as shown in FIG. 4A) and rotate relative to the mounting bracket 411 to abut against the side edge of the slide plate 22 to be in a avoiding position (as shown in FIG. 4B). The detection head 414 is electrically connected to the controller. Figure 2 Figure 3

[0060] In the embodiment, the detection rod 413 is rotatably connected to the mounting bracket 411. When the online detection component 40 is needed to detect the accumulated error of the movement of the slide 21 and the slide plate 22, the detection rod 413 is rotated relative to the mounting bracket 411 to drive the detection head 414 to insert into the detection groove 421 to measure. The measured value is compared with the actual control value to obtain the error value. The error value is fed back to the controller. The controller can control the movement of the slide 21 and the slide plate 22 according to the error value to compensate the error. When the online detection component 40 is not used, the detection rod 413 is rotated relative to the mounting bracket 411 to abut against the side edge of the slide plate 22 to be in the avoiding position. In this way, the detection rod 413 can not interfere with other objects during the operation of the grinding assembly 23. The structure is stable and reliable.

[0061] Further, the detection groove 421 is provided through the standard block 42 along the Y direction. The first end of the detection rod 413 is connected to the mounting bracket 411 through a rotating shaft (not shown in the figure). The axis of the rotating shaft extends along the X direction. In this way, when the detection rod 413 rotates around the X direction to switch between the detection position and the avoiding position, the detection head 414 is more suitable to insert into or rotate out of the detection groove 421 without interfering with the standard block 42. The structure is more suitable for automatic control.

[0062] ​​Further, the detection assembly 41 in the embodiment further comprises a rotating motor 412, which is installed on the mounting bracket 411 and is drivingly connected with the rotating shaft, and the rotating motor 412 is electrically connected with the controller. In the embodiment, by arranging the rotating motor 412 and electrically connecting the rotating motor 412 with the controller, when it is needed to detect the accumulated error generated by the operation of the vertical composite grinding machine, the controller can control the slide rest 21 and the slide plate 22 to move to the initial position, and can control the rotating motor 412 to drive the rotating shaft to drive the detection rod 413 to rotate to switch to the detection position. After the detection rod 413 finishes detection and sends 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 to switch to the avoiding position, which is simple in structure and convenient to control.

[0063] Of course, in other embodiments of the application, the rotating motor 412 can not be arranged, and the detection rod 413 can be hinged on the mounting bracket 411. In this way, during use, the detection rod 413 can be switched between the detection position and the avoiding position by applying external force to the detection rod 413. As long as it is within the concept of the application, other deformation modes are within the protection scope of the application.

[0064] In order to drive the slide plate 22 to move along the Z direction relative to the slide rest 21, the grinding component 20 in the embodiment further comprises a linear rail 24 and a second motor (not shown in the figure), wherein the linear rail 24 is fixedly arranged on the slide rest 21 and extends along the Z direction, the slide plate 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 drivingly connected with the slide plate 22 to drive the slide plate 22 to move along the linear rail 24. During actual driving, a lead screw assembly or other transmission mechanism can be arranged between the second motor and the slide plate 22. During actual work, the displacement of the slide plate 22 along the Z direction will also generate accumulated error. Therefore, the detection head 414 in the embodiment comprises 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 groove 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 further controls the second motor according to the signal transmitted by the detection assembly 41. By detecting the distance between the detection head 414 and the groove side wall of the detection groove 421 through the lateral detection part 4141, the accumulated error of the slide rest 21 and the slide plate 22 along the X direction can be determined; and by the action of the vertical detection part 4142, the accumulated error of the slide plate 22 along the Z direction can be determined.

[0065] Exemplarily, the lateral detection part 4141 and the vertical detection part 4142 in the embodiment can be distance sensors, can also be proximity switches or laser displacement sensors, and other structures capable of detecting distance are within the protection scope of the application.

[0066] Again in combination Figures 1 to 9 As shown, in the embodiment, the detection groove 421 comprises the first groove sidewall 4211 and the second groove sidewall 4212 oppositely arranged and sequentially arranged along the X direction; correspondingly, the lateral detection part 4141 comprises the first lateral detection part 41411 and the second lateral detection part 41412, which are arranged on the opposite sides of the detection rod 413 along the X direction.
