Description

Technical Field

[0001] This invention relates to the field of machine tool adjustment technology, and in particular to a machine tool verticality adjustment device and adjustment method. Background Technology

[0002] Currently, the conventional method for adjusting the perpendicularity accuracy between machine tool motion axes is to use a fastening screw structure. For example, in this embodiment... Figure 1 Taking this scenario as an example, each of the four sliders on the slide block has two adjusting screws on each of the two sliders on each side. By adjusting the screw length of the two upper and lower sliders on one side, the perpendicularity between the slide block in the horizontal direction (left and right in the diagram represent the horizontal direction, and up and down represent the vertical direction) and the first vertical guide rail can be adjusted. After completing the precision adjustment of the first guide rail, the mounting screws of the first guide rail need to be tightened.

[0003] After long-term operation, the lateral screws of the slide block may loosen, causing deformation of nearby structural components and a decrease in the perpendicularity between the motion axes. When the perpendicularity decreases to the point where it cannot meet the processing requirements, it is necessary to disassemble other components connected to the slide block of the first guide rail and adjust the accuracy of the first guide rail of the machine tool. However, the current machine tool design cannot keep track of changes in the perpendicularity of the machine tool in a timely manner. Summary of the Invention

[0004] The purpose of this invention is to provide a machine tool verticality adjustment device and method, which aims to solve the problems of existing technologies that cannot promptly detect changes in machine tool verticality and that verticality adjustment is cumbersome.

[0005] To solve the above-mentioned technical problems, the objective of this invention is achieved through the following technical solution: providing a machine tool verticality adjustment device, comprising:

[0006] The first guide rail is set parallel to the horizontal direction and is equipped with multiple sliders;

[0007] A slide block is mounted on the plurality of sliders and is perpendicular to the horizontal direction;

[0008] A detection component is disposed on the slide block and is used to detect the perpendicularity between the slide block and the first guide rail;

[0009] Multiple adjustment components are disposed inside the slide and distributed along the length direction perpendicular to the slide. The multiple adjustment components can extend out along the length direction parallel to the slide and abut against the corresponding slider.

[0010] A drive component, linked with multiple adjustment components, is used to drive the multiple adjustment components to extend or retract according to the perpendicularity measured by the detection component, so as to adjust the perpendicularity between the slide and the first guide rail.

[0011] Furthermore, a portion of the plurality of adjustment components is disposed on one side of the slide along its length, and another portion of the plurality of adjustment components is disposed on the other side of the slide along its length.

[0012] Furthermore, the detection component includes:

[0013] Two suspended balls are connected by a soft rope and suspended on the slide by gravity;

[0014] Two displacement sensors are mounted on the slide block and correspond one-to-one with the two suspended balls in the horizontal direction. The displacement sensors are used to detect the distance between themselves and the corresponding suspended balls.

[0015] Furthermore, the slide block is provided with multiple hydraulic oil chambers, and the multiple adjustment components are respectively installed in the multiple hydraulic oil chambers;

[0016] The drive assembly is used to input hydraulic oil into the plurality of hydraulic oil chambers respectively, so as to adjust the hydraulic load in the plurality of hydraulic oil chambers, and thereby adjust the distance from which the adjustment assembly extends from the corresponding hydraulic oil chamber.

[0017] Furthermore, the adjustment component includes:

[0018] The protruding part is slidably installed in the corresponding hydraulic oil chamber, with one end extending out of the hydraulic oil chamber to the outside of the slide block and abutting against the corresponding slider;

[0019] A sealing part is fixedly installed inside the slide and sleeved on one end of the protrusion.

[0020] Furthermore, the driving component includes:

[0021] Hydraulic pump;

[0022] An oil supply tank is connected to one end of the hydraulic pump;

[0023] The hydraulic pipeline is connected to the other end of the hydraulic pump and branches out along the pipeline's delivery direction;

[0024] Multiple valve components are installed on various branches of the hydraulic pipeline and are used to connect multiple hydraulic oil chambers;

[0025] Multiple return oil tanks are connected to multiple hydraulic oil chambers through multiple valve components.

[0026] Furthermore, the plurality of valve components include a plurality of check valves and at least one multi-position multi-way solenoid valve, wherein the plurality of check valves are respectively connected to the oil inlet of the plurality of hydraulic oil chambers through a plurality of channels in the corresponding multi-position multi-way solenoid valve.

[0027] The oil outlets of the multiple hydraulic oil chambers are connected to the corresponding return oil tanks through multiple channels in the corresponding multi-position multi-way solenoid valves in one direction.

[0028] This invention also provides a machine tool perpendicularity adjustment method, applied to the machine tool perpendicularity adjustment device described above, comprising:

[0029] The perpendicularity between the slide block and the first guide rail is detected by the detection component.

[0030] When the perpendicularity between the slide block and the first guide rail deflects, the driving component drives the plurality of adjustment components to extend or retract, so that the slide block deflects in the circumferential direction relative to the first guide rail, thereby adjusting the perpendicularity between the slide block and the first guide rail.

[0031] Further, the step of detecting the perpendicularity between the slide and the first guide rail using the detection component includes:

[0032] When the machine tool is in standby mode, the distances between the two displacement sensors and the two suspension balls are detected respectively to obtain the first distance and the second distance;

[0033] When the first distance is greater than a preset standard distance and the second distance is less than a preset standard distance, it is determined that the slide block deflects in the first circumferential direction relative to the first guide rail;

[0034] When the first distance is less than a preset standard distance and the second distance is greater than a preset standard distance, it is determined that the slide block deflects relative to the first guide rail in a second circumferential direction, wherein the first circumferential direction and the second circumferential direction are opposite.

[0035] Further, the step of driving the plurality of adjustment components to extend or retract when the perpendicularity between the slide and the first guide rail deflects, thereby causing the slide to deflect circumferentially relative to the first guide rail and adjusting the perpendicularity between the slide and the first guide rail, includes:

[0036] When the slide deflects in the first circumferential direction relative to the first guide rail, the driving component drives the adjustment component located on one side of the slide in the length direction to retract and extend, so as to cause the slide to rotate and correct in the second circumferential direction relative to the first guide rail.

[0037] When the slide deflects in the second circumferential direction relative to the first guide rail, the driving component drives the adjusting component located on one side of the slide in the length direction to extend and retract, thereby causing the slide to rotate and correct in the first circumferential direction relative to the first guide rail.

[0038] Compared with the prior art, the end cap structure of the present invention has at least the following beneficial effects:

[0039] It can quickly and timely grasp the changes in perpendicularity between the machine tool's motion axes, so as to arrange the machine tool for automatic adjustment and avoid the workpiece defects and production losses caused by the reduction in accuracy to the point that it cannot meet the processing requirements.

[0040] The hydraulic clamping adjustment method replaces the traditional screw adjustment method, avoiding the reduction in accuracy caused by structural loosening and deformation that are inherent in screw adjustment methods.

[0041] In the standby state of the machine tool, the drive component drives multiple adjustment components to adjust the perpendicularity between the slide and the first guide rail, keeping it within a reasonable range and improving the perpendicularity accuracy retention of the machine tool.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0064] Please see Figures 1 to 7 This invention provides a machine tool verticality adjustment device, comprising:

[0065] The first guide rail 1 is set parallel to the horizontal direction and is equipped with multiple sliders 2;

[0066] The slide block 3 is mounted on multiple sliders 2 and is perpendicular to the horizontal direction;

[0067] The detection component 4 is mounted on the slide 3 and is used to detect the perpendicularity between the slide 3 and the first guide rail 1.

[0068] Multiple adjustment components 5 are disposed inside the slide block 3 and distributed along the length direction perpendicular to the slide block 3. The multiple adjustment components 5 can extend out along the length direction parallel to the slide block 3 and abut against the corresponding slider 2.

[0069] The drive component 6, in conjunction with multiple adjustment components 5, is used to drive the multiple adjustment components 5 to extend or retract according to the perpendicularity measured by the detection component 4, so as to adjust the perpendicularity between the slide 3 and the first guide rail 1.

[0070] Please continue reading. Figure 1 and Figure 2In this embodiment, the first guide rail 1 can be one or more, preferably two arranged parallel to the horizontal direction, and these two first guide rails 1 are arranged vertically. Multiple sliders 2 are mounted on the two first guide rails 1. The number of sliders 2 is not specifically limited, but preferably four are symmetrically distributed on the two first guide rails 1. Four sliders 2 are mounted on the four corners of the back side of the slide block 3. Two second guide rails 32 (for loading the processed parts) are provided along the length of the front side of the slide block 3. Ideally, the slide block 3 is perpendicular to the first guide rail 1, that is, the second guide rails 32 are perpendicular to the first guide rail 1; this ensures the accuracy of the processed parts during processing. However, in practical applications, the slide block 3 may deflect after long-term operation, causing a deviation in the perpendicularity between the slide block 3 and the first guide rail 1, thereby affecting the processing accuracy of the processed parts on the slide block 3. Therefore, this embodiment specifically designs an adjustment device for on-machine detection, adjustment, and control of the perpendicularity between the slide block 3 and the first guide rail 1.

[0071] Specifically, in this embodiment, the perpendicularity between the slide block 3 and the first guide rail 1 is detected by the detection component 4. When the perpendicularity between the slide block 3 and the first guide rail 1 deviates, the drive component 6 drives multiple adjustment components 5 to extend or retract, causing the slide block 3 to deflect circumferentially relative to the first guide rail 1, thereby adjusting the perpendicularity between the slide block 3 and the first guide rail 1. Based on this, the on-machine detection, adjustment, and control functions of the perpendicularity of the machine tool's axis motion are realized, ensuring that the perpendicularity of the machine tool is maintained within the accuracy requirements before machining parts, thereby improving the machining accuracy of the machine tool and extending its service life.

[0072] Please continue reading. Figure 5 and Figure 6 In one embodiment, a portion of the plurality of adjustment components 5 is disposed on one side of the slide 3 along its length, and another portion of the plurality of adjustment components 5 is disposed on the other side of the slide 3 along its length.

[0073] This layout in the embodiment optimizes the adjustment function of the slide block 3, thereby improving the overall efficiency and ease of adjustment.

[0074] Specifically, the adjusting components 5 extend parallel to the length of the slide block 3 and abut against the corresponding slider 2. Therefore, when each adjusting component 5 extends to a different length, the slide block 3 rotates relative to the slider 2. The slider 2 is mounted on the first guide rail 1, meaning that when each adjusting component 5 extends to a different length, the slide block 3 rotates relative to the first guide rail 1. Thus, to adjust the perpendicularity between the slide block 3 and the first guide rail 1, some of the adjusting components 5 can be concentrated on one side of the slide block 3's length direction (i.e.,...). Figure 5 The lower left side of the viewing angle), and another part of the adjustment components 5 are concentrated on the other side of the length direction of the slide block 3 (i.e., the lower left side of the viewing angle). Figure 5 (Lower right side of the viewpoint). Understandably, assuming that extending the lower left adjustment component 5 and retracting the lower right adjustment component 5 controls the sliding block 3 to rotate clockwise (to... Figure 5 Taking the viewing direction as an example, multiple adjustment components 5 on both sides of the slide block 3 extend to different lengths, which can realize the clockwise or counterclockwise rotation adjustment of the slide block 3, thereby realizing the verticality adjustment between the slide block 3 and the first guide rail 1.

[0075] Please continue reading. Figure 3 and Figure 4 In one embodiment, the detection component 4 includes:

[0076] Two suspended balls 41 are connected by a soft rope and suspended on the slide block 3 by gravity;

[0077] Two displacement sensors 42 are mounted on the slide block 3 and correspond one-to-one with the two suspension balls 41 in the horizontal direction. The displacement sensors 42 are used to detect the distance between themselves and the corresponding suspension balls 41.

[0078] In this embodiment, the detection component 4 can quickly and timely grasp the changes in perpendicularity between the machine tool's motion axes, so as to arrange the machine tool for automatic adjustment and avoid the workpiece defects and production losses caused by the accuracy being reduced to the point that it cannot meet the processing requirements.

[0079] Specifically, when the slide block 3 deflects, the two displacement sensors 42 will deflect accordingly, but the two suspended balls 41 will not deflect under the action of gravity. Assuming the slide block 3 deflects clockwise (with... Figure 4 Taking the viewing direction as an example, the upper displacement sensor 42 will move away from the upper suspension ball 41, and the lower displacement sensor 42 will move closer to the lower suspension ball 41. At this time, the distance between the two displacement sensors 42 and the two suspension balls 41 will change. Based on this, the deflection of the slide block 3 can be obtained by detecting the distance between the two displacement sensors 42 and the corresponding suspension ball 41, thus providing a precise basis for the subsequent adjustment of the adjustment component 5.

[0080] More specifically, with the slide 3 perpendicular to the first guide rail 1, the distances between the two displacement sensors 42 and the two suspension balls 41 can be pre-acquired, namely the first distance and the second distance. Ideally, the first distance and the second distance are equal and can be defined as the standard distance. In subsequent detection processes, if the first distance and the second distance change, it indicates that the slide 3 has deflected. If the deflection exceeds the accuracy range, it can be automatically adjusted by the drive component 6 and the adjustment component 5 in the machine tool standby state.

[0081] More specifically, continue to combine Figure 4 The specific implementation of the example will be described from... Figure 4 From the perspective direction, you can see Figure 4 In Figure (a), the ideal state is when the slide block 3 and the first guide rail 1 are perpendicular to each other. In this state, the first distance α1 and the second distance α2 measured by the two displacement sensors 42 are equal. Figure 4 In diagram (b), the slide 3 is deflected clockwise relative to the first guide rail 1. The two displacement sensors 42 also deflect clockwise with the slide 3. However, the two suspension balls 41 are naturally suspended due to gravity, so they do not deflect with the slide 3. At this time, the first distance β1 and the second distance β2 measured by the two displacement sensors 42 change; that is, the first distance β1 is greater than the first distance α1, and the second distance β2 is less than the second distance α2. From this, the deflection of the slide 3 can be calculated. Then, the drive assembly 6 drives the extension movement of the adjustment assembly 5 on one side of the slide 3, while the adjustment assembly 5 on the other side retracts. This causes the position of the slide 3 relative to the slider 2 to rotate, that is, relative to the first guide rail 1, thereby adjusting the perpendicularity of the slide 3 to the first guide rail 1.

[0082] In one embodiment, the slide 3 is provided with a plurality of hydraulic oil chambers 31, and a plurality of adjustment components 5 are respectively installed in the plurality of hydraulic oil chambers 31; the drive component 6 is used to input hydraulic oil into the plurality of hydraulic oil chambers 31 respectively to adjust the hydraulic load in the plurality of hydraulic oil chambers 31, thereby adjusting the distance from which the adjustment component 5 extends out of the corresponding hydraulic oil chamber 31.

[0083] In this embodiment, an adjustment component 5 is installed in one hydraulic oil chamber 31. The drive component 6 can independently input different amounts of hydraulic oil into multiple hydraulic oil chambers 31. The increase or decrease in the amount of hydraulic oil in the hydraulic oil chambers 31 will result in different extension distances of the adjustment component 5, thereby achieving corresponding adjustments according to the deflection of the slide 3. It can be understood that the design of the drive component 6 allows for precise control of the flow rate and pressure of the hydraulic oil, ensuring accurate control of the extension distance of each adjustment component 5, and ensuring the accuracy of the deflection adjustment of the slide 3. In addition, the drive component 6 automatically adjusts based on the detection results of the detection component 4, reducing the need for manual intervention and making the operation of the machine tool more intelligent and automated.

[0084] In this embodiment, a hydraulic adjustment method is used instead of the traditional screw adjustment method, which avoids the reduction in accuracy caused by structural loosening and deformation that are inherent in screw adjustment methods.

[0085] In one embodiment, the adjustment component 5 includes a protrusion 51 and a sealing portion 52. The protrusion 51 is slidably installed in the corresponding hydraulic oil chamber 31, and one end of the protrusion 51 extends from the hydraulic oil chamber 31 to the outside of the slide block 3 and abuts against the corresponding slider 2; the sealing portion 52 is fixedly installed in the slide block 3 and sleeved on one end of the protrusion 51.

[0086] In this embodiment, an opening facing the corresponding slider 2 is formed in the hydraulic oil chamber 31. The sealing part 52 adopts a piston seal ring with an annular structure, which is fixed in the opening. The protruding part 51 can be a piston, with one end passing through the sealing part 52 and extending to the outside of the slide block 3. The protruding end of the piston abuts against the corresponding slider 2. Based on this design, when different amounts of hydraulic oil are input into the hydraulic oil chamber 31 by the drive assembly 6, different degrees of hydraulic load will be generated in the hydraulic oil chamber 31, thereby driving the protruding part 51 to extend outwards by different distances. It can be understood that the greater the hydraulic load in the hydraulic oil chamber 31, the greater the distance the protruding part 51 extends outwards.

[0087] In one embodiment, the drive assembly 6 includes a hydraulic pump 62, a supply tank 61, hydraulic lines, multiple valves, and multiple return tanks 67.

[0088] The oil supply tank 61 is connected to one end of the hydraulic pump 62;

[0089] The hydraulic pipeline is connected to the other end of the hydraulic pump 62 and branches out along the pipeline delivery direction;

[0090] Multiple valve components are installed on various branches of the hydraulic pipeline and are used to connect multiple hydraulic oil chambers 31;

[0091] Multiple return oil tanks 67 are connected to multiple hydraulic oil chambers 31 through multiple valve components.

[0092] In this embodiment, the hydraulic pipeline may include a main oil line 63 and multiple branch oil lines 64. The hydraulic pump 62 is used to deliver hydraulic oil from the supply tank 61 to each hydraulic oil chamber 31 through the main oil line 63 and multiple branch oil lines 64. The branch design of the hydraulic pipeline ensures that hydraulic oil can be delivered to multiple hydraulic oil chambers 31 separately, improving the adjustment efficiency. Valves are used to precisely control the flow direction and flow rate of the hydraulic oil, ensuring that the hydraulic oil chambers 31 receive the appropriate amount of hydraulic oil, thereby driving the extension 51 to extend the required distance, and thus achieving precise adjustment of the deflection of the precision slide 3. The return oil tank 67 is used to collect the hydraulic oil returning from the hydraulic oil chambers 31, ensuring the recycling of the hydraulic system and reducing hydraulic oil waste. In this way, the machine tool's verticality adjustment device can quickly respond and accurately adjust the machine tool's verticality to meet different processing requirements.

[0093] In one embodiment, the multiple valve components include multiple check valves 65 and at least one multi-position multi-way solenoid valve 66. The multiple check valves 65 are connected unidirectionally to the inlets of multiple hydraulic oil chambers 31 through multiple channels in the corresponding multi-position multi-way solenoid valve 66. The outlets of the multiple hydraulic oil chambers 31 are connected unidirectionally to the corresponding return oil tanks 67 through multiple channels in the corresponding multi-position multi-way solenoid valve 66.

[0094] In this embodiment, each hydraulic oil chamber 31 has an oil inlet and an oil outlet. Multiple channels of the multi-position multi-way solenoid valve 66 can be connected to the oil inlets and outlets of multiple hydraulic oil chambers 31 simultaneously. The check valve 65 can be connected to the corresponding multi-position multi-way solenoid valve 66 to achieve a one-way connection with one of the oil inlets, so as to realize the input of hydraulic oil to the oil inlet. The oil outlet of the hydraulic oil chamber 31 is connected to the corresponding return oil tank 67 through the corresponding multi-position multi-way solenoid valve 66. The multi-position multi-way solenoid valve 66 can control the opening and closing of the oil outlet.

[0095] For ease of understanding, combined with Figure 7 The specific embodiment of the example is described below. Four hydraulic oil chambers 31 and four corresponding adjustment components 5 are provided in the slide 3. The main oil circuit 63 branches into four branch oil circuits 64. There are four check valves 65, which are respectively set in the four branch oil circuits 64. The multi-position multi-way solenoid valve 66 adopts a three-position four-way solenoid valve, that is, two three-position four-way solenoid valves need to be set. Two adjacent branch oil circuits 64 are connected to a three-position four-way solenoid valve as a group. The four channels of a three-position four-way solenoid valve are respectively connected to two oil inlets and two oil outlets in two hydraulic oil chambers 31. The four channels are individually controlled to open and close by electromagnetic switches. Based on this, hydraulic oil is drawn from the oil supply tank 61 by the hydraulic pump 62 and delivered to the main oil circuit 63. After passing through the four branch oil circuits 64 of the main oil circuit 63, it can be injected unidirectionally into two three-position four-way solenoid valves. By controlling the opening and closing of each channel in the three-position four-way solenoid valves, the four branches can be independently controlled to input hydraulic oil of different flow rates to the four hydraulic oils, and the four hydraulic oils can be independently controlled to output hydraulic oil of different flow rates to the return oil tank 67.

[0096] In some other embodiments, the drive assembly 6 may also include an overflow valve 68, one end of which is connected to the main oil circuit 63 and the other end is connected to an overflow tank 69. Its function is to open when the hydraulic system pressure exceeds the set value, so as to discharge the excess hydraulic oil into the overflow tank 69 to protect the hydraulic pipeline from overpressure damage.

[0097] This invention also provides a machine tool perpendicularity adjustment method, applied to the machine tool perpendicularity adjustment device described above, such as... Figure 8 As shown, steps S801 to S802 are included.

[0098] S801, The perpendicularity between the slide block 3 and the first guide rail 1 is detected by the detection component 4;

[0099] S802. When the perpendicularity between the slide block 3 and the first guide rail 1 is deflected, the drive assembly 6 drives multiple adjustment assemblies 5 to extend or retract, so that the slide block 3 deflects in the circumferential direction relative to the first guide rail 1, thereby adjusting the perpendicularity between the slide block 3 and the first guide rail 1.

[0100] Based on steps S801 to S802, this embodiment realizes the in-machine detection, adjustment and control functions of the perpendicularity of the machine tool axis movement, so that the perpendicularity of the machine tool is kept within the accuracy requirement range before machining parts, thereby improving the machining accuracy of the machine tool and extending the service life of the machine tool.

[0101] like Figure 9 As shown, in one embodiment, step S801 includes:

[0102] S901. In the standby state of the machine tool, the distances between the two displacement sensors 42 and the two suspension balls 41 are detected by the two displacement sensors 42 respectively, and the first distance and the second distance are obtained.

[0103] S902. When the first distance is greater than the preset standard distance and the second distance is less than the preset standard distance, it is determined that the slide block 3 deflects in the first circumferential direction relative to the first guide rail 1.

[0104] S903. When the first distance is less than the preset standard distance and the second distance is greater than the preset standard distance, it is determined that the slide block 3 deflects relative to the first guide rail 1 in the second circumferential direction, wherein the first circumferential direction and the second circumferential direction are opposite.

[0105] In this embodiment, the process of steps S901 to S903 detects the deflection of the slide block 3 relative to the first guide rail 1, so as to provide a precise basis for the subsequent adjustment of the adjustment component 5.

[0106] like Figure 10 As shown, in one embodiment, step S802 includes:

[0107] S1001. When the slide block 3 deflects in the first circumferential direction relative to the first guide rail 1, the adjustment component 5 located on one side of the slide block 3 in the length direction is driven to retract by the drive component 6, and the adjustment component 5 located on one side of the slide block 3 in the length direction is driven to extend, so as to cause the slide block 3 to rotate and correct in the second circumferential direction relative to the first guide rail 1.

[0108] S1002. When the slide block 3 deflects in the second circumferential direction relative to the first guide rail 1, the adjustment component 5 located on one side of the slide block 3 in the length direction is driven to extend by the drive component 6, and the adjustment component 5 located on one side of the slide block 3 in the length direction is driven to retract, so as to cause the slide block 3 to rotate and correct in the first circumferential direction relative to the first guide rail 1.
