Description

Technical Field

[0001] This invention relates to the field of machine tool technology, and more specifically, to a vertical compound grinding machine. Background Technology

[0002] Vertical compound grinders are high-precision machine tools that integrate multiple grinding functions. Their vertical layout minimizes the impact of gravity and clamping forces on workpiece machining, thus achieving higher machining accuracy.

[0003] In related technologies, for example, the X-axis of the dual-head vertical grinder disclosed in patent document CN118905869A is driven by dual lead screws. The cumulative error of the transmission system leads to low machining accuracy and relatively low grinding accuracy of the workpiece. Summary of the Invention

[0006] A base component, the base component including a base, a crossbeam and a worktable, the worktable being rotatably disposed on the base, the crossbeam being disposed on the base and located on the outer periphery of the worktable, and the crossbeam extending along the X direction;

[0007] A grinding component, comprising a drive assembly, a slide, a slide plate, a hydrostatic rotary table, and a grinding assembly, wherein the drive assembly comprises a first motor and a lead screw mechanism, the lead screw mechanism being connected to the first motor, the slide being movably mounted on the lead screw mechanism, the slide plate being mounted on the slide and movable along the Z direction, the grinding assembly being mounted on the hydrostatic rotary table and located above the worktable, and the hydrostatic rotary table being mounted on the slide and rotatable in the XZ plane;

[0008] An online detection component includes a detection assembly and a standard block. The online detection component is disposed on the slide, and the standard block is installed on the base and located on the outer periphery of the worktable. The detection assembly moves with the slide and cooperates with the standard block to detect and determine the movement error of the slide.

[0009] A controller is electrically connected to the detection component and controls the first motor according to the signals transmitted by the detection component.

[0010] Furthermore, the standard block is provided with a detection groove, and the detection component includes:

[0011] Mounting bracket, the mounting bracket being fixed to the slide;

[0012] A detection rod, one end of which is rotatably mounted on the mounting bracket, and the other end of which is provided with a detection head. The detection rod has a detection position that rotates relative to the mounting bracket to drive the detection head into the detection groove. The detection rod also has a clearance position that rotates relative to the mounting bracket to abut against the side of the slide. The detection head is electrically connected to the controller.

[0013] Furthermore, the detection groove extends through the standard block along the Y direction, and the first end of the detection rod is connected to the mounting bracket via a rotating shaft, the axis of which extends along the X direction.

[0014] Furthermore, the detection component also includes a rotary motor, which is mounted on the mounting bracket and drivenly connected to the rotary shaft, and the rotary motor is electrically connected to the controller.

[0015] Furthermore, the grinding component also includes a linear guide and a second motor. The linear guide is fixedly mounted on the slide saddle and extends along the Z direction. The slide is mounted on the linear guide and can move along the length of the linear guide. The second motor is drivenly connected to the slide.

[0016] The detection head includes a lateral detection section and a vertical detection section. The lateral detection section is used to detect the distance between the detection head and the sidewall of the detection groove, and the vertical detection section is used to detect the distance between the detection head and the bottom surface of the detection groove.

[0017] The controller also controls the second motor based on the signals transmitted by the detection component.

[0018] Furthermore, the detection groove includes a first groove sidewall and a second groove sidewall disposed opposite to each other, the first groove sidewall and the second groove sidewall being arranged sequentially along the X direction;

[0019] The lateral detection unit includes a first lateral detection unit and a second lateral detection unit, which are disposed on opposite sides of the detection head along the X direction.

[0020] Furthermore, the grinding assembly includes:

[0021] A grinding support is fixedly installed on the hydrostatic rotary table;

[0022] The grinding section includes multiple hydrostatic spindles and various types of grinding tools. The various types of grinding tools can be selectively mounted on at least one of the hydrostatic spindles, and the axes of the multiple hydrostatic spindles are parallel or intersecting.

[0023] Furthermore, the grinding tools include internal grinding tools and external grinding tools, and at least the internal grinding tools have different models.

[0026] Furthermore, the tool holder and the standard block are respectively disposed on both sides of the worktable along the X direction.

[0027] In this application, the drive assembly includes a lead screw mechanism and a first motor. A slide saddle is movably mounted on the lead screw mechanism. When the first motor drives the lead screw mechanism to rotate, it can move the slide saddle along the length direction of the lead screw mechanism, i.e., the X direction. During this process, due to the influence of the thread structure on the lead screw in the lead screw mechanism, accumulated errors are easily generated during the movement of the slide saddle. In this application, the vertical compound grinding machine is equipped with an online detection component. The detection component of this online detection component is mounted on the slide. When the slide saddle moves, the detection component can move synchronously along the X direction, and the standard block of the online detection component is set on the base. In actual use, by cooperating with the detection component and the standard block for detection, the accumulated errors generated during the movement of the slide saddle and slide along the X direction can be determined. Subsequently, the controller can control the first motor according to the signal transmitted by the detection component, thereby compensating for the accumulated errors generated during the movement of the slide saddle and slide along the X direction driven by the lead screw mechanism, and thus ensuring the machining accuracy of the workpiece by the grinding assembly mounted on the slide.

Detailed Implementation

[0043] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0045] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0046] As described in the background section, existing grinding machines use lead screw drives, which accumulate errors and easily reduce the grinding accuracy of the workpiece. Therefore, this application provides a novel vertical compound grinding machine. The vertical compound grinding machine of this application will be described in detail below with reference to the accompanying drawings.

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

[0048] The base component 10 includes a base 11, a crossbeam 12, and a worktable 13. The worktable 13 is rotatably mounted on the base 11. The crossbeam 12 is mounted on the base 11 and located on the outer periphery of the worktable 13, extending along the X-direction. The grinding component 20 includes a drive assembly 25, a slide 21, a slide plate 22, a hydrostatic rotary table 26, and a grinding assembly 23. The drive assembly 25 includes a first motor 251 and a lead screw mechanism 252. The lead screw mechanism 252 is connected to the first motor 251. The slide 21 is movably mounted on the lead screw mechanism 252. The slide plate 22 is mounted on the slide 21 and can move along the Z-direction. The grinding assembly 23 is mounted on the hydrostatic rotary table 26 and located above the worktable 13. The hydrostatic rotary table 26 is mounted on the slide 22 and can rotate in the XZ plane. The online detection component 40 includes a detection component 41 and a standard block 42. The detection component 41 is set on the slide 22, and the standard block 42 is mounted on the base 11 and located on the outer periphery of the worktable 13. The detection component 41 moves with the slide 22 and cooperates with the standard block 42 to detect and 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.

[0049] When grinding a workpiece using the vertical compound grinding machine in this embodiment, the workpiece is placed on the worktable 13. Then, the drive assembly 25 drives the slide 21 to move along the length direction of the crossbeam 12, i.e., the X direction, and drives the slide 22, hydrostatic rotary table 26, and grinding assembly 23 mounted on the slide 21 to move synchronously. Simultaneously, the slide 22 is controlled to move along the Z direction according to processing needs to adjust the relative positional relationship between the grinding assembly 23 and the workpiece. Furthermore, the grinding assembly 23 is mounted on the hydrostatic rotary table 26. When the hydrostatic rotary table 26 rotates in the XZ plane, it can drive the grinding assembly 23 to rotate to a certain angle. Combined with the rotation of the worktable 13, the workpiece placed on the worktable 13 can be ground.

[0050] In this embodiment, the drive assembly 25 includes a lead screw mechanism 252 and a first motor 251. The slide saddle 21 is movably mounted on the lead screw mechanism 252. When the first motor 251 drives the lead screw mechanism 252 to rotate, it can drive the slide saddle 21 to move along the length direction of the lead screw mechanism 252, i.e., the X direction. During this process, due to the influence of the thread structure on the screw in the lead screw mechanism 252, the slide saddle 21 is prone to accumulating errors during its movement. In this application, the vertical composite grinding machine is provided with an online detection assembly 41. The detection component 41 of the online detection assembly 41 is mounted on the slide 22. When the slide saddle 21 moves, the detection component 41 can move synchronously along the X direction, and the standard block 42 of the online detection component 40 is set on the base 11. In actual use, by using the detection component 41 in conjunction with the standard block 42 to detect the accumulated error generated during the movement of the slide saddle 21 and slide plate 22 in the X direction, the controller can then control the first motor 251 according to the signal transmitted by the detection component 41, thereby compensating for the accumulated error generated during the movement of the slide saddle 21 and slide plate 22 in the X direction driven by the lead screw mechanism 252, and thus ensuring the machining accuracy of the workpiece by the grinding component 23 installed on the slide plate 22.

[0051] It is understandable that when the slide 22 moves along the Z direction on the slide saddle 21, accumulated errors will also occur. In this embodiment, by installing the detection component 41 on the slide 22, and using the standard block 42 in conjunction with the corresponding detection method, the accumulated error 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 online detection component 40, the online detection component 40 can detect the accumulated error of the slide 22 in both the X and Z directions, and can work with the controller to calibrate the accumulated error during the movement of the slide 22 in a timely manner, thereby improving the machining accuracy of the workpiece by the grinding component 23 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 in 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 plate 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 (e.g., rotatable relative to the mounting bracket 411 to drive the detection head 414 into the detection groove 421) that allows it to rotate relative to the mounting bracket 411. Figure 2 (as shown) and rotate relative to the mounting bracket 411 to a clearance position set against the side of the slide plate 22 (as shown) Figure 3 As shown), 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 the online detection component 40 is needed to detect the accumulated movement error of the slide saddle 21, slide plate 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. The measured value is then compared with the actual controlled value to obtain the error value. This error value is then fed back to the controller, which can control the movement of the slide saddle 21, slide plate 22, etc., based on the error value to perform error compensation. 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 a position close to the side of the slide plate 22 to avoid interference with other objects during the operation of the grinding assembly 23, thus ensuring structural stability and reliability.

[0054] Furthermore, in this embodiment, the detection groove 421 is disposed 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 this 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 insert into the detection groove 421 or rotate out of the detection groove 421, without interfering with the standard block 42, and is more suitable for automatic control.

[0055] Furthermore, the detection component 41 in this embodiment also includes a rotary motor 412, which is mounted on the mounting bracket 411 and driven by the rotary shaft, and is electrically connected to the controller. In this embodiment, by setting the rotary motor 412 and electrically connecting it to the controller, when it is necessary to detect the accumulated error generated by the operation of the vertical compound grinding machine, only a control command needs to be sent to the controller. The controller can then control the slide saddle 21 and the slide plate 22 to move to the initial position, and simultaneously control the rotary motor 412 to drive the rotary shaft to rotate the detection rod 413 to 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 rotary motor 412 to drive the rotary shaft to rotate the detection rod 413 to switch to the avoidance position. The structure is simple and easy to control.

[0056] Of course, in other embodiments of this application, the rotary motor 412 may not be provided, and the detection rod 413 may be hinged to the mounting bracket 411. With this configuration, when in use, by applying an external force to the detection rod 413, the detection rod 413 can be rotated to switch between the detection position and the avoidance position. Any other modifications under the concept of this application are within the protection scope of this application.

[0057] To drive the slide 22 to move relative to the slide saddle 21 in the Z direction, the grinding component 20 in this embodiment also includes a linear guide 24 and a second motor (not shown in the figure). The linear guide 24 is fixedly mounted on the slide saddle 21 and extends in the Z direction. The slide 22 is mounted on the linear guide 24 and can move along the length of the linear guide 24. The second motor is driven by the slide 22 to drive the slide 22 to move along the linear guide 24. In actual operation, a lead screw assembly or other transmission mechanism can also be provided between the second motor and the slide 22. During actual operation, the displacement of the slide 22 in the Z direction will also generate accumulated errors. Therefore, 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 sidewall of the detection groove 421, and the vertical detection part 4142 is used to detect the distance between the detection head 414 and the bottom surface 4213 of the detection groove 421. 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 sidewall of the detection groove 421 by the lateral detection unit 4141, the accumulated error of the slide 21 and slide plate 22 along the X direction can be determined; by the action of the vertical detection unit 4142, the accumulated error of the slide plate 22 along the Z direction can be determined.

[0058] For example, the lateral detection unit 4141 and the vertical detection unit 4142 in this embodiment can be a distance sensor, a proximity switch, or a laser displacement sensor, etc. Any other structural component that can detect distance is within the protection scope of this application.

[0059] Combined again Figures 1 to 9 As shown, in this embodiment, the detection groove 421 includes a first groove sidewall 4211 and a second groove sidewall 4212 disposed opposite to each other, and the first groove sidewall 4211 and the second groove sidewall 4212 are arranged sequentially along the X direction; correspondingly, the lateral detection part 4141 includes a first lateral detection part 41411 and a second lateral detection part 41412, and the first lateral detection part 41411 and the second lateral detection part 41412 are disposed on opposite sides of the detection rod 413 along the X direction. In actual use, the first lateral detection unit 41411 faces the first groove sidewall 4211 and is used to detect the distance between the detection head 414 and the first groove sidewall 4211; the second lateral detection unit 41412 faces the second groove sidewall 4212 and is used to detect the distance between the detection head 414 and the second groove sidewall 4212. The first lateral detection unit 41411 and the second lateral detection unit 41412 respectively detect the distance between the detection head 414 and the second groove sidewall 4212. The distance between the first groove sidewall 4211 and the second groove sidewall 4212, when calculating the accumulated error of the slide saddle 21 and the slide plate 22 along the X direction, can be calculated by combining the detection results of the first lateral detection unit 41411 and the second lateral detection unit 41412. This 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 error, which is conducive to further improving the processing accuracy of the vertical composite grinding machine 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 section. The grinding bracket 234 is fixedly mounted on the hydrostatic rotary table 26. The grinding section includes multiple hydrostatic spindles 231 and various types of grinding tools 235. The various types of grinding tools 235 can be selectively mounted on at least one hydrostatic spindle 231, and the axes of the multiple hydrostatic spindles 231 are parallel or intersecting. That is, the multiple hydrostatic spindles 231 on the grinding bracket 234 in this embodiment can be arranged in parallel or not in parallel, and there can be two, three, or more hydrostatic spindles 231. This application shows the case where there are two hydrostatic spindles 231. The two hydrostatic spindles 231 are arranged in parallel, and the ends of the two hydrostatic spindles 231 used to mount the grinding tools 235 are respectively located at opposite ends of the grinding bracket 234. This facilitates the equalization of the force exerted by the hydrostatic spindles 231 on the mounting bracket 411.

[0061] Furthermore, in this embodiment, by setting multiple hydrostatic spindles 231, multiple grinding tools 235 can be installed, and these grinding tools 235 have various different models. Different models of grinding tools 235 can meet different grinding requirements. In actual use, the hydrostatic rotary table 26 can be driven to rotate, thereby driving the multiple hydrostatic spindles 231 to rotate, and thus different types of processing can be performed on the surface of the workpiece, which can improve the processing efficiency of the vertical composite grinding machine in this embodiment.

[0062] Meanwhile, in this embodiment, various types of grinding tools 235 can be selectively installed on the same hydrostatic spindle 231. Thus, by replacing different types of grinding tools 235, different processing requirements of the workpiece can be met.

[0063] Exemplarily, the grinding tool 235 in this embodiment includes internal grinding tools and external grinding tools, with at least the internal grinding tools having different models. In actual machining, mounting external grinding tools on the hydrostatic spindle 231 facilitates surface machining of the workpiece, while mounting internal grinding tools on the hydrostatic spindle 231 facilitates grinding of internal cavities, through holes, etc., on the workpiece. Furthermore, by providing multiple models of internal grinding tools in this embodiment, the grinding requirements for different types of internal cavities and through holes can be met, thus expanding the application scenarios of the vertical composite grinding machine in this embodiment.

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

[0065] Furthermore, the vertical compound grinding machine in this embodiment also includes a tool holder 60, which is mounted on the base 11 and located on the outer periphery of the worktable 13. A rotatable rotary disk 61 is mounted on the tool holder 60, and multiple tool placement positions 611 are arranged circumferentially on the rotary disk 61. Various types of grinding tools 235 are correspondingly positioned in each of the multiple tool placement positions 611. In this embodiment, by setting up the tool holder 60 to store and place different types of grinding tools 235, and by rotating the rotary disk 61, the corresponding grinding tools 235 can be rotated to a position suitable for replacement and operation, thereby improving the ease of use of the vertical compound grinding machine in this embodiment.

[0066] For example, in this embodiment, the tool placement position 611 can be a placement slot, a placement buckle, or other structures, and is not specifically limited in this application.

[0067] Furthermore, the tool holder 60 and the standard block 42 are respectively disposed on both sides of the worktable 13 along the X direction. In this embodiment, by disposing the tool holder 60 and the standard block 42 on both sides of the worktable 13 along the X direction, it is more suitable to make reasonable use of the space on the base 11, which facilitates the miniaturization and integration design of the vertical compound grinding machine and can reduce the production cost of the vertical compound grinding machine in this embodiment to a certain extent.

[0068] Combination Figures 1 to 12 As shown, the vertical composite grinder in this embodiment also includes a support component 30, and the grinding assembly 23 includes a first tube 232 and a second tube 233. One end of the first tube 232 is vertically fixed to the center of the hydrostatic rotary table 26. The second tube 233 is connected to the first tube 232 and coaxially arranged with it. The second tube 233 can rotate relative to the first tube 232 around its own axis. The first tube 232 and the second tube 233 are provided with interconnected liquid channels, which are connected to the liquid channels on the hydrostatic spindle 231 through pipes. The support component 30 is fixedly connected to the slide 22 and extends in the Y direction in front of the table surface of the hydrostatic rotary table 26. The second tube 233 is rotatably mounted on the support component 30. It should be noted that the liquid channels in this embodiment include hydraulic oil channels and coolant channels, etc. Correspondingly, the pipes include hydraulic oil pipes and coolant pipes, etc.

[0069] In this embodiment, the first tube 232 and the second tube 233 are provided with interconnected liquid channels. These liquid channels are connected to the liquid channel on the hydrostatic spindle 231 via pipes. When the hydrostatic turntable 26 rotates, the hydrostatic spindle 231 and the first tube 232 can rotate synchronously with the hydrostatic turntable 26, while the second tube 233 can rotate relative to the first tube 232. At this time, when a pipe is provided in the space outside the first tube 232 and the second tube 233, the rotation of the second tube 233 can drive the pipe connected to one side of the second tube 233 to move. For example, when the first tube 232 rotates clockwise, the second tube 233 can also rotate clockwise synchronously, thereby avoiding pipe entanglement. The internal communication method of the first tube 232 and the second tube 233 is consistent with the rotary connection device in patent document 202311790494.3, and will not be described in detail in this application.

[0070] Furthermore, in this application, the vertical compound grinding machine is also provided with a support 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 hydrostatic rotary table 26. In actual installation, the second tube 233 is rotatably mounted on the support component 30. Through the action of the support component 30, the second tube 233 can be stably supported in front of the hydrostatic rotary table 26, and it is not easy for the second tube 233 to be pulled or torn due to the numerous pipes outside the second tube 233. The structure is stable and can improve the service life of the vertical compound grinding machine of this application.

[0071] Specifically, the support component 30 in this embodiment includes a support frame 31, which has a clearance space 311 for avoiding the hydrostatic spindle 231. When the hydrostatic turntable 26 drives the hydrostatic spindle 231 to rotate, the clearance space 311 prevents interference between the support frame 31 and the hydrostatic spindle 231. Optionally, the support frame 31 in this embodiment can be U-shaped or C-shaped, with the hollow portion of the U-shaped or C-shaped structure forming the aforementioned clearance space 311. This structure is simple and easy to implement. In actual production, the support frame 31 in this embodiment can be fixed to the slide plate 22 by screws, clips, welding, etc. Any other modifications within the scope of this application are within the protection scope of this application.

[0072] Furthermore, in this embodiment, a pipe connector 80 is provided at the end of the second pipe body 233 near the support frame 31. A pipe (not shown in the figure) is provided inside the support frame 31, and the pipe is connected to the pipe connector 80 for conveying liquid. In this embodiment, by providing a pipe inside the support frame 31 and connecting the pipe to the pipe connector 80, this arrangement not only disperses the pipes on the outer periphery of the first pipe body 232 and the second pipe body 233, avoiding interference between the pipes when the hydrostatic turntable 26 rotates, but also optimizes the arrangement of the pipes, preventing the pipes from being exposed to the external environment, thereby reducing the risk of the pipes being damaged by external structures.

[0073] Optionally, in an embodiment of this application (not shown), to prevent the pipe fitting 80 from rotating and twisting the pipe installed in the support frame 31 when the second pipe body 233 rotates, a rotatable third pipe body (not shown) can be provided at one end of the second pipe body 233 near the support frame 31, and the internal flow channel of the third pipe body is adaptively connected to the internal flow channel of the second pipe body 233 (i.e., ensuring that the corresponding delivery channel can flow the corresponding fluid), and then the pipe fitting 80 can be connected to the third pipe body.

[0074] Furthermore, the support frame 31 of this application is provided with a cavity 312, an opening 313, and a cover plate 314. The opening 313 communicates with the cavity 312 and faces the end of the second pipe body 233 near the support frame 31. The cover plate 314 is detachably provided in the opening 313, and the pipe connector 80 is located inside the cavity 312. In this embodiment, by installing the pipe connector 80 inside the cavity 312, the pipe connector 80 can be prevented from being exposed to the external environment. In addition, the opening 313 is provided at the position where the support frame 31 faces the second pipe body 233, which facilitates the assembly and maintenance of the pipeline. At the same time, the cover plate 314 is provided on the support frame 31 to cover the opening 313. When assembly and maintenance are required, the cover plate 314 can be removed; when assembly and maintenance are not required, the cover plate 314 can be put on. Optionally, in this embodiment, the cover plate 314 can be fixed to the support frame 31 by screws, pins, etc.

[0075] Furthermore, the vertical grinding machine in this embodiment also includes a dressing device 50, with a tool holder 60 mounted on the side of the dressing device 50 away from it. The dressing device 50 includes a slide rail component 51, a support base 52, and a dresser 53. The slide rail component 51 is disposed on the base 11 and located on the outer periphery of the worktable 13, extending along the Y direction. The support base 52 is mounted on the slide rail component 51 and can slide along the length of the slide rail component 51. The dresser 53 is mounted on the support base 52. In this embodiment, the slide rail component 51 includes a slide rail, a motor, and a lead screw. The motor is driven and connected to the lead screw, and the support base 52 is connected to the lead screw and can slide on the slide rail. When the motor drives the lead screw to rotate, it can cause the support base 52 to slide on the slide rail. This allows the dresser 53 and the support base 52 to avoid the grinding assembly 23 and the workpiece being processed during grinding by the grinding assembly 23. At the same time, when the support 52 slides along the slide rail component 51, the distance between the dresser 53 and the grinding assembly 23 can be adjusted, so that the dresser 53 can be driven to dress the grinding tool 235 mounted on the hydrostatic spindle 231.

[0076] Optionally, the dresser 53 in this embodiment includes an electric spindle grinding wheel dresser 531 and a single-point diamond pen dresser 532. The electric spindle grinding wheel dresser 531 is driven by an electric spindle, with the roller rotating relative to the grinding wheel to be dressed. The roller crushes and smooths the surface of the grinding wheel, removing grinding debris, abrasive particles, and adhesives adhering to the dulled grinding wheel, bringing the grinding wheel to its optimal state for dressing external cylindrical grinding tools. The single-point diamond pen dresser 532 has advantages such as simple structure, good wear resistance, and high strength, facilitating the dressing of internal and external cylindrical grinding tools.

[0077] As can be seen from the above embodiments, the compound vertical grinder, with its dual grinding heads for external and internal grinding, enables convenient workpiece clamping and allows for the completion of compound grinding processes such as internal and external diameters, end faces, and conical surfaces in a single clamping operation. This avoids errors caused by multiple clamping operations and improves machining accuracy and efficiency. Furthermore, the machine tool boasts strong modularity, equipped with online measurement and calibration devices, and a multi-functional grinding wheel dressing device. This enables online workpiece measurement, drive shaft positioning and repeatability error detection and compensation, and online grinding wheel dressing, further enhancing machining accuracy.

[0078] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0079] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0080] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
