DETAILED DESCRIPTION

[0043] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0046] As described in the background technology, the grinding machine in the prior art is driven by a lead screw. The error accumulation of this transmission mode easily reduces the grinding accuracy of the grinding machine on the workpiece. For this reason, the present application provides a new type of vertical compound grinding machine. The vertical compound grinding machine of the present application will be described in detail below in conjunction with the accompanying drawings.

[0047] See also Figures 1 to 12 As shown, according to an embodiment of the present application, a vertical compound grinding machine is provided. The vertical compound grinding machine comprises a base component 10, a grinding component 20, an online detection component 40 and a controller (not shown in the figure).

[0048] The base component 10 includes a base 11, a beam 12 and a workbench 13. The workbench 13 is rotatably 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 driving component 25, a saddle 21, a slide 22, a static pressure turntable 26 and a grinding component 23. The driving component 25 includes a first motor 251 and a screw mechanism 252. The screw mechanism 252 is connected to the first motor 251. The saddle 21 is movably installed on the screw mechanism 252. The slide 22 is installed on the saddle 21 and can be moved along the Z direction. The grinding assembly 23 is mounted on the hydrostatic turntable 26 and is located above the workbench 13. The hydrostatic turntable 26 is mounted on the slide 22 and can rotate in the XZ plane. The online detection component 40 includes a detection assembly 41 and a standard block 42. The detection assembly 41 is arranged on the slide 22. The standard block 42 is mounted on the base 11 and is located on the outer peripheral side of the workbench 13. The detection assembly 41 moves with the slide 22 and cooperates with the standard block 42 for detection to determine the movement error of the slide 22. The controller is electrically connected to the detection assembly 41 and controls the first motor 251 according to the signal transmitted by the detection assembly 41.

[0049] When the vertical compound grinding machine in this embodiment is used to grind the workpiece, the workpiece is placed on the workbench 13. Thereafter, the driving assembly 25 is used to drive the saddle 21 to move along the length direction of the beam 12, that is, the X direction, and drive the slide plate 22, the hydrostatic turntable 26 and the grinding assembly 23 installed on the saddle 21 to move synchronously. 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. 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 placed on the workbench 13.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] Combine again Figures 1 to 9 As shown, in this embodiment, the detection groove 421 includes a first groove side wall 4211 and a second groove side wall 4212 that are oppositely arranged, and the first groove side wall 4211 and the second groove side wall 4212 are arranged in sequence along the X direction; correspondingly, the lateral detection portion 4141 includes a first lateral detection portion 41411 and a second lateral detection portion 41412, and the first lateral detection portion 41411 and the second lateral detection portion 41412 are arranged on opposite sides of the detection rod 413 along the X direction. In actual use, the first lateral detection portion 41411 is directly opposite to the first groove side wall 4211, and the first lateral detection portion 41411 is used to detect the distance between the detection head 414 and the first groove side wall 4211; the second lateral detection portion 41412 is directly opposite to the second groove side wall 4212, and the second lateral detection portion 41412 is used to detect the distance between the detection head 414 and the second groove side wall 4212. The first lateral detection portion 41411 and the second lateral detection portion 41412 respectively detect the detection head 414 With respect to the spacing between the first groove side wall 4211 and the second groove side wall 4212, when calculating the accumulated errors of the saddle 21 and the slide 22 along the X direction, the accumulated errors can be calculated by combining the detection results of the first lateral detection unit 41411 and the second lateral detection unit 41412, which can improve the detection accuracy of the online detection component 40 to a certain extent, and is more suitable for the controller to accurately control the first motor 251 to accurately compensate for the accumulated errors, so as to further improve the machining accuracy of the vertical compound grinder in this embodiment.

[0060] Combination Figures 1 to 5 , Figures 10 to 12As shown, the grinding assembly 23 in this embodiment includes a grinding bracket 234 and a grinding part. Among them, the grinding bracket 234 is fixedly installed on the hydrostatic turntable 26; the grinding part includes multiple hydrostatic spindles 231 and multiple different types of grinding tools 235, and the multiple different types of grinding tools 235 can be selectively installed on at least one hydrostatic spindle 231, and the axial directions of the multiple hydrostatic spindles 231 are parallel or intersecting. That is to say, the multiple hydrostatic spindles 231 on the grinding bracket 234 in this embodiment can be arranged in parallel or not in parallel, and the hydrostatic spindles 231 can be two, three or more than three. The present application shows the situation when there are two hydrostatic spindles 231. The two hydrostatic spindles 231 are arranged in parallel, and one end of the two hydrostatic spindles 231 for mounting the grinding tool 235 is respectively located at the opposite ends of the grinding bracket 234. In this way, it is convenient to balance the force applied by the hydrostatic spindle 231 to the mounting bracket 411.

[0061] In addition, in this embodiment, by setting up multiple hydrostatic spindles 231, multiple grinding tools 235 can be installed, and the grinding tools 235 have multiple different models. Different models of grinding tools 235 can meet different grinding needs. In actual use, the hydrostatic turntable 26 can be driven to rotate to drive multiple hydrostatic spindles 231 to rotate, and then different types of processing can be performed on the surface of the workpiece, which can improve the processing efficiency of the vertical compound grinder on the workpiece in this embodiment.

[0062] At the same time, a plurality of different types of grinding tools 235 can be selectively installed on the same static pressure spindle 231 in this embodiment. Thus, by replacing different types of grinding tools 235, different processing requirements of workpieces can also be met.

[0063] Exemplarily, the grinding tool 235 in this embodiment includes an inner cylindrical grinding tool and an outer cylindrical grinding tool, and at least the inner cylindrical grinding tool has different models. During actual processing, by installing the outer cylindrical grinding tool on the static pressure spindle 231, it is convenient to process the surface of the workpiece, and by installing the inner cylindrical grinding tool on the static pressure spindle 231, it is convenient to grind the inner cavity, through hole, etc. on the workpiece. In addition, in this embodiment, by setting the inner cylindrical grinding tool to multiple models, the grinding requirements of different types of inner cavities and through holes can be met, which can increase the use scenarios of the vertical compound grinder in this embodiment.

[0064] In this embodiment, a hydrostatic spindle 231 is used to drive a grinding tool 235 to process a workpiece. Compared with a common rotating shaft structure, the hydrostatic spindle 231 has higher operating stability and is more suitable for high-precision processing of the workpiece.

[0065] Furthermore, the vertical compound grinder in the present embodiment further includes a tool holder 60, which is mounted on the base 11 and located on the outer peripheral side of the workbench 13. A rotatable rotating disk 61 is mounted on the tool holder 60, and a plurality of tool placement positions 611 are provided in the circumferential direction of the rotating disk 61. A plurality of different types of grinding tools 235 are arranged one by one in the plurality of tool placement positions 611. In the present embodiment, by providing the tool holder 60 to store and place different types of grinding tools 235, the rotating disk 61 is rotated, and the corresponding grinding tool 235 can be rotated to a position suitable for replacement and operation, which can improve the convenience of use of the vertical compound grinder in the present embodiment.

[0066] Exemplarily, in this embodiment, the tool placement position 611 can be a placement slot, a placement buckle, or other structure, which is not specifically limited in this application.

[0067] Furthermore, the tool rest 60 and the standard block 42 are respectively arranged on both sides of the workbench 13 along the X direction. In this embodiment, by respectively arranging the tool rest 60 and the standard block 42 on both sides of the workbench 13 along the X direction, it is more suitable for rationally utilizing the space on the base 11, facilitating the miniaturization and integrated design of the vertical compound grinder, and can reduce the production cost of the vertical compound grinder in this embodiment to a certain extent.

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.

[0073] 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.

[0074] 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.

[0075] Furthermore, the vertical grinder in this embodiment also includes a dressing device 50, and the tool holder 60 is installed on the side of the dressing device 50 away from the dressing device 50.
