Description

Technical Field

[0001] The invention relates to the technical field of machine tool adjustment, and in particular to a machine tool verticality adjustment device and an adjustment method. Background Art

[0002] At present, the conventional method for adjusting the verticality accuracy between the moving axes of a machine tool is to use a fastening screw structure for adjustment. Figure 1 Take the scenario as an example. Among the four sliders on the slide, two sliders on each side are equipped with two adjustment screws. By adjusting the screw-in length of the two sliders on one side, the vertical assembly adjustment between the horizontal direction of the slide (the left and right direction is the horizontal direction, and the up and down direction is the vertical direction) and the vertical first guide rail can be achieved. After completing the precision debugging 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 slider become loose, the nearby structural parts are deformed, and the verticality between the moving axes decreases. When it is reduced to a level that cannot meet the processing requirements, it is necessary to disassemble other components connected to the first guide slider and adjust the accuracy of the first guide of the machine tool. However, in the current machine tool design, it is impossible to grasp the changes in the verticality of the machine tool in time. Summary of the invention

[0004] The purpose of the present invention is to provide a machine tool verticality adjustment device and adjustment method, aiming to solve the problem that the prior art cannot timely grasp the verticality change of the machine tool and the verticality adjustment is relatively cumbersome.

[0024] A plurality of valve members, arranged on each branch of the hydraulic pipeline and used to connect a plurality of hydraulic oil chambers;

[0025] A plurality of oil return tanks are connected to a plurality of hydraulic oil chambers through a plurality of valve components.

[0026] Further, the plurality of valve components include a plurality of one-way valves and at least one multi-position multi-way solenoid valve, and the plurality of one-way valves are unidirectionally connected to the oil inlets of the plurality of hydraulic oil chambers through a plurality of channels in the corresponding multi-position multi-way solenoid valves;

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

[0029] Detecting the verticality between the slide and the first guide rail by the detection component;

[0030] When the verticality between the slide and the first guide rail is deflected, the driving assembly drives the multiple adjustment assemblies to extend or retract, so that the slide deflects in the circumferential direction relative to the first guide rail, thereby adjusting the verticality between the slide and the first guide rail.

[0031] Furthermore, the step of detecting the verticality between the slide and the first guide rail by the detection component includes:

[0032] When the machine tool is in a standby state, the two displacement sensors respectively detect the distances between them and the two suspension balls to obtain a first distance and a 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 seat deflects in a first circumferential direction relative to the first guide rail;

[0034] When the first distance is smaller than a preset standard distance and the second distance is larger than a preset standard distance, it is determined that the slide is deflected in a second circumferential direction relative to the first guide rail, wherein the first circumferential direction is opposite to the second circumferential direction.

[0035] Furthermore, when the verticality between the slide and the first guide rail is deflected, the step of driving the plurality of adjustment components to extend or retract by the driving component so that the slide deflects in a circumferential direction relative to the first guide rail, thereby adjusting the verticality between the slide and the first guide rail, includes:

[0036] When the slide is deflected in a first circumferential direction relative to the first guide rail, the drive assembly drives the adjustment assembly located on one side of the slide in the length direction to retract and drives the adjustment assembly located on one side of the slide in the length direction to extend, so as to cause the slide to rotate and correct in a second circumferential direction relative to the first guide rail;

[0037] When the slide is deflected in the second circumferential direction relative to the first guide rail, the driving component drives the adjustment component located on one side of the length direction of the slide to extend and drives the adjustment component located on one side of the length direction of the slide to retract, so as to cause the slide to rotate and correct in the first circumferential direction relative to the first guide rail.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0064] See also Figures 1 to 7 , an embodiment of the present invention provides a machine tool verticality adjustment device, comprising:

[0065] A first guide rail 1 is arranged parallel to the horizontal direction and is equipped with a plurality of sliders 2;

[0066] A slide seat 3 is installed on the plurality of slide blocks 2 and is perpendicular to the horizontal direction;

[0067] A detection component 4 is disposed on the slide 3 and is used to detect the verticality between the slide 3 and the first guide rail 1;

[0068] A plurality of adjustment components 5 are arranged inside the slide 3 and distributed along a length direction perpendicular to the slide 3. The plurality of adjustment components 5 can extend along a length direction parallel to the slide 3 and abut against the corresponding slider 2;

[0069] The driving assembly 6 is linked with the plurality of adjusting assemblies 5 and is used to drive the plurality of adjusting assemblies 5 to extend or retract respectively according to the verticality measured by the detecting assembly 4 so as to adjust the verticality 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 and arranged parallel to the horizontal direction, and the two first guide rails 1 are arranged up and down. A plurality of sliders 2 are mounted on the two first guide rails 1 in a matching manner. The number of sliders 2 is not specifically limited, preferably four and symmetrically distributed on the two first guide rails 1. The four corners on the back side of the slide 3 are mounted on the four sliders 2, and two second guide rails 32 (for loading processing parts) are provided on the front side of the slide 3 along its length direction. Ideally, the slide 3 is kept perpendicular to the first guide rail 1, that is, the second guide rail 32 is kept perpendicular to the first guide rail 1; this can ensure the accuracy of the processing parts during processing. However, in actual applications, the slide 3 may deflect after long-term operation, resulting in deviation in the verticality of the slide 3 and the first guide rail 1, thereby affecting the processing accuracy of the processing parts on the slide 3. Therefore, this embodiment is specially designed with an adjustment device for detecting, adjusting and controlling the verticality between the slide 3 and the first guide rail 1 on the machine.

[0071] Specifically, in this embodiment, the verticality between the slide 3 and the first guide rail 1 is detected by the detection component 4; when the verticality between the slide 3 and the first guide rail 1 is deflected, the driving component 6 drives the multiple adjustment components 5 to extend or retract, so that the slide 3 deflects in the circumferential direction relative to the first guide rail 1, and then adjusts the verticality between the slide 3 and the first guide rail 1. Based on this, the on-machine detection, adjustment and control functions of the verticality of the inter-axis motion of the machine tool are realized, so that the verticality of the machine tool before processing the parts is kept within the accuracy requirement range, so as to improve the processing accuracy of the machine tool and extend the service life of the machine tool.

[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 length direction of the slide 3 , and another portion of the plurality of adjustment components 5 is disposed on the other side of the length direction of the slide 3 .

[0073] This layout of the present embodiment optimizes the adjustment function of the slide seat 3, thereby improving the overall use efficiency and the convenience of adjustment.

[0074] Specifically, the adjustment components 5 extend in a direction parallel to the length of the slide 3 and abut against the corresponding slider 2. Therefore, when each adjustment component 5 extends to a different length, the slide 3 will rotate relative to the slider 2. The slider 2 is matched with the first guide rail 1, that is, when each adjustment component 5 extends to a different length, the slide 3 will rotate relative to the first guide rail 1. In this way, in order to adjust the verticality between the slide 3 and the first guide rail 1, a part of the adjustment components 5 can be concentrated on one side of the length direction of the slide 3 (i.e. Figure 5 The other part of the adjustment assembly 5 is centrally arranged on the other side of the length direction of the slide 3 (i.e. Figure 5 It can be understood that, assuming that the adjustment component 5 on the lower left side is extended and the adjustment component 5 on the lower right side is retracted, the slide 3 can be rotated clockwise (by Figure 5 Taking the viewing angle direction as an example), that is, controlling the multiple adjustment components 5 on both sides of the length direction of the slide 3 to extend to different lengths, the slide 3 can be rotated clockwise or counterclockwise, thereby achieving the verticality adjustment between the slide 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 suspension balls 41 are connected in series by a soft rope and are suspended on the slide 3 by gravity;

[0077] Two displacement sensors 42 are disposed on the slide seat 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 verticality changes between the machine tool's motion axes, so as to arrange the machine tool to perform automatic adjustments, thereby avoiding the reduction of accuracy to the point where it cannot meet the processing requirements, resulting in workpiece defects and production losses.

[0079] Specifically, when the slide 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 that the slide 3 deflects clockwise (with Figure 4 Taking the viewing angle direction as an example), the upper one of the two displacement sensors 42 will be away from the upper one of the two suspension balls 41, and the lower one of the two displacement sensors 42 will be close to the lower one of the two suspension balls 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 3 can be obtained by detecting the distance between the two displacement sensors 42 and the corresponding suspension balls 41, thereby providing an accurate basis for the subsequent adjustment of the adjustment component 5.

[0080] More specifically, when the slide 3 is perpendicular to the first guide rail 1, the distances between the two displacement sensors 42 and the two suspension balls 41, i.e., the first distance and the second distance, can be obtained in advance. Ideally, the first distance and the second distance are equal and can be defined as standard distances. In this way, in the subsequent detection process, if the first distance and the second distance change, it means that the slide 3 has deflected. When the deflection exceeds the accuracy range, it can be automatically adjusted by the drive component 6 and the adjustment component 5 in the standby state of the machine tool.

[0081] More specifically, continue to combine Figure 4 The specific embodiments of the examples are described below. Figure 4 The viewing direction can be seen Figure 4 (a) is an ideal state when the slide 3 and the first guide rail 1 are perpendicular to each other, and at this time, the first distance α1 and the second distance α2 measured by the two displacement sensors 42 are equal; and Figure 4 (b) is the state when the slide 3 deflects clockwise relative to the first guide rail 1. The two displacement sensors 42 also deflect clockwise with the slide 3, but the two suspension balls 41 are naturally suspended due to gravity, so the two suspension balls 41 will 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 have changed, 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; thus, the deflection of the slide 3 can be calculated. Then, the adjustment component 5 on one side of the slide 3 is driven to extend through the driving component 6, while the adjustment component 5 on the other side is retracted, so that the slide 3 can rotate relative to the slider 2, that is, rotate relative to the first guide rail 1, so as to adjust the verticality of the slide 3 and the first guide rail 1.

[0082] In one embodiment, a plurality of hydraulic oil chambers 31 are provided in the slide seat 3, and a plurality of adjustment components 5 are respectively installed in the plurality of hydraulic oil chambers 31; the driving component 6 is used to input hydraulic oil into the plurality of hydraulic oil chambers 31 respectively, so as to adjust the hydraulic load in the plurality of hydraulic oil chambers 31, and further adjust the distance that the adjustment component 5 extends from the corresponding hydraulic oil chamber 31.

[0083] In this embodiment, an adjustment component 5 is installed in a hydraulic oil chamber 31, and 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 chamber 31 will cause the extension distance of the adjustment component 5 to be different, thereby realizing corresponding adjustment according to the deflection of the slide 3. It can be understood that the design of the drive component 6 allows for fine control of the flow and pressure of the hydraulic oil, ensuring that the extension distance of each adjustment component 5 is accurately controlled to ensure the accuracy of the deflection adjustment of the slide 3. In addition, the drive component 6 is automatically adjusted 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 to replace the traditional screw adjustment method, thereby avoiding the reduction in accuracy caused by the looseness and deformation of the structure in the screw adjustment method.

[0085] In one embodiment, the adjustment assembly 5 includes an extension portion 51 and a sealing portion 52. The extension portion 51 is slidably mounted in the corresponding hydraulic oil chamber 31, and one end of the extension portion 51 passes through the hydraulic oil chamber 31 to the outside of the slide seat 3 and abuts against the corresponding slider 2; the sealing portion 52 is fixedly mounted in the slide seat 3 and sleeved on one end of the extension portion 51.

[0086] In this embodiment, an opening is provided in the hydraulic oil chamber 31, which faces the corresponding slider 2. The sealing portion 52 is a piston sealing ring with an annular structure. The sealing portion 52 is fixed in the opening. The extension portion 51 can be a piston. One end of the piston passes through the sealing portion 52 and extends to the outside of the slide seat 3. The extended 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 through the driving component 6, different degrees of hydraulic load will be generated in the hydraulic oil chamber 31, thereby driving the extension portion 51 to extend to different distances. It can be understood that the greater the hydraulic load in the hydraulic oil chamber 31, the greater the distance the extension portion 51 extends.

[0087] In one embodiment, the driving assembly 6 includes a hydraulic pump 62 , an oil supply tank 61 , hydraulic pipelines, a plurality of valve components and a plurality of oil 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 is branched along the pipeline delivery direction;

[0090] A plurality of valve components are arranged on each branch of the hydraulic pipeline and are used to connect a plurality of hydraulic oil chambers 31;

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

[0092] In this embodiment, the hydraulic pipeline may include a main oil circuit 63 and multiple branch oil circuits 64, and the hydraulic pump 62 is used to transport the hydraulic oil in the oil supply tank 61 to each hydraulic oil chamber 31 through the main oil circuit 63 and multiple branch oil circuits 64. The branch design of the hydraulic pipeline ensures that the hydraulic oil can be transported to multiple hydraulic oil chambers 31 respectively, thereby improving the adjustment efficiency. The valve member is used to accurately control the flow direction and flow rate of the hydraulic oil to ensure that the hydraulic oil chamber 31 can obtain suitable hydraulic oil, thereby driving the extension portion 51 to extend the required distance, thereby achieving precise adjustment of the deflection of the precision slide 3. The return oil tank 67 is used to collect the hydraulic oil refluxed from the hydraulic oil chamber 31 to ensure the recycling of the hydraulic system and reduce the waste of hydraulic oil. In this way, the verticality adjustment device of the machine tool can quickly respond and accurately adjust the verticality of the machine tool to meet different processing requirements.

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

[0094] In this embodiment, each hydraulic oil chamber 31 has an oil inlet and an oil outlet. The multiple channels of the multi-position multi-way solenoid valve 66 can simultaneously connect the oil inlets and oil outlets of multiple hydraulic oil chambers 31. The one-way 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 to achieve 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, and the multi-position multi-way solenoid valve 66 can control the disconnection of the oil outlet.

[0095] For ease of understanding, combined Figure 7 A specific embodiment of the example is described, four hydraulic oil chambers 31 and corresponding four adjustment components 5 are set in the slide 3, the main oil circuit 63 branches into four branch oil circuits 64, the number of the one-way valves 65 is four and they are respectively arranged 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, and the four channels of a three-position four-way solenoid valve are respectively connected to the two oil inlets and two oil outlets in the two hydraulic oil chambers 31, and the four channels are individually controlled to be opened and closed by electromagnetic switches. Based on this, the hydraulic oil in the oil supply tank 61 is extracted 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 unidirectionally injected into the two three-position four-way solenoid valves. By controlling the on / off and opening size of each channel in the three-position four-way solenoid valve, 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 tank 67.

[0096] In some other embodiments, the drive assembly 6 may further 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 box 69. The overflow valve 68 opens when the hydraulic system pressure exceeds a set value to discharge excess hydraulic oil into the overflow box 69 to protect the hydraulic pipeline from over-pressure damage.

[0097] The embodiment of the present invention also provides a machine tool verticality adjustment method, which is applied to the above machine tool verticality adjustment device, such as Figure 8 As shown, it includes steps S801 to 802.

[0098] S801, detecting the verticality between the slide 3 and the first guide rail 1 by the detection component 4;

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

[0100] Based on steps S801 to S802, this embodiment realizes the on-machine detection, adjustment and control functions of the verticality of the machine tool's inter-axis motion, so that the verticality of the machine tool before processing parts is maintained within the accuracy requirement range, thereby improving the machine tool's processing accuracy and extending the machine tool's service life.

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

[0102] S901, when the machine tool is in standby state, two displacement sensors 42 are used to respectively detect the distances between them and the two suspension balls 41 to obtain a first distance and a second distance;

[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 3 is deflected in the first circumferential direction relative to the first guide rail 1;

[0104] S903. When the first distance is smaller than a preset standard distance and the second distance is larger than the preset standard distance, it is determined that the slide 3 is deflected in a second circumferential direction relative to the first guide rail 1, wherein the first circumferential direction is opposite to the second circumferential direction.

[0105] In this embodiment, the deflection of the slide 3 relative to the first guide rail 1 is detected through the process of steps S901 to S903, so as to provide an accurate basis for the subsequent adjustment of the adjustment component 5.

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

[0107] S1001, when the slide 3 deflects in a first circumferential direction relative to the first guide rail 1, the adjustment assembly 5 located on one side of the length direction of the slide 3 is driven to retract and extend through the driving assembly 6, so as to cause the slide 3 to rotate and correct in a second circumferential direction relative to the first guide rail 1;

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