These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present invention. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.
As shown in fig. 1 and 3, a method for comparing and verifying the installation accuracy of a guide rail is completed by using a comparison and verification tool, wherein the tool comprises an installation block 2 installed on a machine tool 1, an installation position 6 is arranged on the installation block 2, a shoulder 4 is arranged on one side of the installation position 6, and a pressing block 3 is detachably arranged on the side opposite to the shoulder 4. The mounting block 2 is fixed to the machine tool 1 by screws, the shoulder 4 is usually provided on the mounting block 2, and the shoulder 4 can support the mounting of the guide rail 5, but the guide rail 5 is likely to be deviated after being mounted due to excessive contact between the guide rail 5 and the shoulder 4, and finally the mounting accuracy of the guide rail 5 cannot meet the requirement.
The method comprises the following steps:
s100, mounting a plurality of mounting blocks 2 on the lathe body of the lathe 1, wherein mounting positions 6 of the mounting blocks 2 correspond to different mounting surface accuracies; respectively installing the X guide rails 5 on different installation blocks 2 to obtain installation precision data sets C of the X guide rails 5 on the different installation blocks 2; obtaining the lowest mounting surface precision of the guide rail 5 matched with the guide rail A through comparison and analysis; the data set comprises at least three sets of data, i.e. at least one guide rail 5 is mounted on three different mounting blocks 2. The specific method comprises the following steps:
comparing the installation precision data in the installation precision data set C with the installation precision requirement data of the X guide rail 5;
screening out qualified installation blocks 2 meeting the installation precision requirement of the X guide rail 5;
and selecting the lowest mounting surface precision value in the qualified mounting block 2 as the lowest mounting surface precision of the X guide rail 5.
S200, recording a first installation accuracy A1 of the X guide rail 5 on one of the installation blocks 2, and recording a second installation accuracy A2 of the X guide rail 5 on the installation block 2 after the installation block is placed for N hours; comparing the difference Δ a 'between a1 and a2, if Δ a' is greater than the first threshold value, it is determined that the pressing block 3 needs to be added when the X-rail 5 is mounted on the mounting block 2.
S300, mounting different guide rails 5 on one mounting block 2; acquiring installation precision data of different guide rails 5 on the installation block 2; screening out qualified guide rails 5 meeting the installation accuracy requirement of the installation block 2 according to the obtained installation accuracy data; and selecting the lowest precision value in the qualified guide rail 5 as the lowest precision guide rail 5 matched with the mounting block 2. The different guide rails 5 here comprise at least three guide rails 5 with different levels of precision. The higher the accuracy grade of the guide rail 5, the higher the manufacturing cost. The lowest-precision guide rail 5 suitable for the selected mounting block 2 is selected by the method, so that the production requirement is met, and the cost of the machine tool 1 is reduced.
It should be noted that the X-rail 5 in the present application does not refer to a specific X-type rail 5, but is expressed for convenience. In the present application, the installation accuracy of the guide rail 5 is mainly represented by the straightness of the guide rail 5 after installation, and how to measure the straightness of the guide rail 5 through the autocollimator is the prior art in the field, and therefore, the inventor does not describe the measurement again.
In the present application, N > 24, i.e. the mounting accuracy of the guide rail 5 on the machine tool 1 is measured again after 24 hours. Because the guide rail 5 is fixed on the machine tool 1 through the screw, and the shoulder 4 is arranged on the machine tool 1, the guide rail 5 cannot ensure that the shoulder 4 does not extrude and displace the guide rail 5 from the shoulder 4 when the guide rail 5 is installed on the machine tool 1 through the screw because the length of the guide rail 5 is long. Therefore, the installation accuracy of the guide rail 5 needs to be measured again after the guide rail 5 is installed for the first time and is left for more than 24 hours, which can ensure that the installation accuracy data of the guide rail 5 is accurate. The value of N in the present application ranges from 24 to 72 unless otherwise specified.
According to the method for the comparison and verification of the installation accuracy of the guide rail 5, the method is realized through a comparison and verification tool, and multiple groups of experiments are carried out by arranging the installation block 2 on the machine tool 1 and arranging the pressing block 3 on the installation block 2. The mounting precision of the guide rail 5 on the machine tool 1 is improved by acquiring the mounting precision data of the guide rail 5 with the same precision on different mounting surfaces and comparing the mounting precision data with the mounting precision data to obtain the mounting surface precision matched with the guide rail 5. And comparing the data before and after the guide rail 5 is installed to obtain whether the pressing block 3 is required to be installed in the installation process of the guide rail 5. The method can obtain the accuracy requirement of the proper installation surface of the guide rail 5, can provide data support for the installation of the guide rail 5 of the machine tool 1, and is favorable for improving the installation accuracy of the guide rail 5 on the machine tool 1.
Further, the screening out the qualified guide rail 5 meeting the installation accuracy requirement of the installation block 2 according to the obtained installation accuracy data comprises:
acquiring a required value of installation accuracy of the installation block 2 and the guide rail 5;
and screening out data higher than the installation precision required value from the installation precision data.
In engineering application, each mounting block 2 has a corresponding mounting precision requirement of the guide rail 5, namely, the mounting precision value meeting the requirement is met, and the guide rail 5 can normally work after being mounted on the machine tool 1. The higher the installation accuracy is, the smaller the numerical value is, and in practical application, the installation accuracy of a certain type of guide rail 5 obtained by measurement is smaller than the installation accuracy required value, so that the installation accuracy of the guide rail 5 can be required.
Further, the acquiring of the mounting accuracy data sets C of the X guide rail 5 on the different mounting blocks 2 includes:
installing the X guide rail 5 on different installation blocks 2;
fine-adjusting the installation precision of the X guide rail 5 until the installation precision is improved to be smaller than a second threshold value;
after leaving for N hours, the mounting accuracy data of the X rail 5 on each mounting block 2 is recorded as a mounting accuracy data set C.
Further, the values of the first threshold value and the second threshold value are different depending on the guide rail 5 and the mounting block 2. The first threshold value and the second threshold value may be obtained through experiments or may be obtained through production experience.
As shown in fig. 2, the present invention further provides a guide rail installation method, which adopts the comparison verification method as described above to verify the installation accuracy of the guide rail, and the method includes the following steps:
s10, mounting the mounting block 2 on the machine tool 1; the mounting block 2 is fixed to the machine tool 1 by screws.
S20, mounting the guide rail 5 on the mounting block 2, and recording the first mounting precision A1 of the guide rail 5;
s30, after the guide rail is placed for N hours, recording the second installation accuracy A2 of the guide rail 5 again;
s40, comparing A1 and A2, and if the difference value delta A' between A1 and A2 is smaller than a first threshold value, completing the installation of the guide rail 5; if the difference Δ a' between a1 and a2 is greater than the first threshold value, the pressing block 3 is mounted on the mounting block 2, and the pressing block 3 is abutted against the guide rail 5.
By comparing the data of the two measurements, it can be known whether the guide rail 5 is displaced after being mounted on the mounting block 2, and the difference Δ a' between a1 and a2 is smaller than the first threshold value, then the guide rail 5 is not displaced after being mounted or is in an acceptable displacement range. If the difference Δ a' between a1 and a2 is greater than the first threshold, the guide rail 5 is displaced greatly after being installed, and the normal operation of the equipment on the guide rail 5 is affected after the guide rail 5 is installed, so that the guide rail 5 needs to be corrected by adding the pressing block 3.
Further, the method further comprises:
s50, recording the third installation accuracy A3 of the guide rail 5 after adding the pressing block 3;
s60, after the guide rail is placed for N hours, recording the fourth installation accuracy A4 of the guide rail 5 again;
s70, comparing A3 and A4, and if the difference value delta A' between A3 and A4 is smaller than a first threshold value, finishing the installation of the guide rail 5; if the difference Δ a ″ between A3 and a4 is greater than the first threshold value, the guide rail 5 of different accuracy is replaced.
Further, the mounting block 2 is fixed on the machine tool 1 by screws, and the pressing block 3 is fixed on the mounting block 2 by screws.
If the guide rail 5 is displaced after the press block 3 is mounted, i.e. the difference Δ a "between A3 and a4 is greater than the first threshold value, it indicates that the guide rail 5 does not match the mounting block 2, and the guide rail 5 with a different accuracy grade needs to be replaced.
By the method, the installation accuracy of the guide rail 5 on the installation block 2 or the machine tool 1 can be ensured, and the equipment on the guide rail 5 can normally run after the guide rail 5 is installed.
Having described embodiments of the present application, the foregoing description is intended to be exemplary, not exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen in order to best explain the principles of the embodiments, the practical application, or improvements made to the technology in the marketplace, or to enable others of ordinary skill in the art to understand the embodiments disclosed herein.
