After the hydraulic guide rail is assembled, oil circuit pressure resistance testing and oil circuit flushing processes are needed, and then the hydraulic guide rail is installed on the mounting plate. The accuracy of the position of the hydraulic guide rail during installation directly affects the use quality and effect in the later period, and therefore, the installation accuracy detection of the position during installation and in the later use is particularly crucial. SUMMARY

[0003] The main purpose of the application is to provide a numerical control hydraulic guide rail installation method, which performs straightening inspection on the hydraulic guide rail during installation on the mounting plate and in the working process in the later period by means of a laser scanning module, a processing module and an image acquisition module, so as to determine whether the hydraulic guide rail is within the reference coordinate area of the mounting plate, and the method has the advantages of high efficiency, intelligence and periodic detection.

[0004] To achieve the above purpose, the application provides a numerical control hydraulic guide rail straightening method for installing a hydraulic guide rail, which comprises the following steps:

[0005] Before the hydraulic guide rail is installed on the mounting plate:

[0006] Step S1: a laser scanning module performs laser scanning on the mounting plate of the hydraulic guide rail to be installed, so as to obtain scanning data of the mounting plate and transmit the scanning data to a processing module, so that the processing module obtains an initial coordinate graph based on the mounting plate;

[0007] Step S2: the processing module obtains installation position data of the hydraulic guide rail on the mounting plate and marks installation contour point positions of the hydraulic guide rail on the initial coordinate graph, so as to obtain an installation reference coordinate graph of the hydraulic guide rail;

[0008] Step S3: the processing module produces a laser indication instruction according to the installation reference coordinate graph and transmits the laser indication instruction to the laser scanning module, so that the laser scanning module emits an indication laser based on the installation contour point positions on the mounting plate (which is convenient for installation according to the indication laser);

[0009] After the hydraulic guide rail is pre-installed on the mounting plate:

[0010] Step S4: an image acquisition module performs image acquisition on the mounting plate of the pre-installed hydraulic guide rail, so as to obtain pre-installation image data of the hydraulic guide rail on the mounting plate and transmit the pre-installation image data to the processing module, so that the processing module obtains a pre-installation position of the hydraulic guide rail on the mounting plate and converts it into a pre-installation coordinate graph;

[0011] Step S5: The processing module compares the pre-installation coordinate map with the reference coordinate map to determine whether the pre-installation coordinate of the hydraulic guide rail relative to the mounting plate is within the error of the reference coordinate.

[0012] As a further preferred technical solution of the above technical solution, step S5 is specifically implemented as the following steps:

[0013] Step S5.1: If the pre-installation coordinate is within the error of the reference coordinate, a first display is performed by the display module to indicate that the hydraulic guide rail is installed in place on the mounting plate, and the pre-installed hydraulic guide rail is formally installed on the mounting plate, thereby completing the installation of the hydraulic guide rail;

[0014] Step S5.2: If the pre-installation coordinate is not within the error of the reference coordinate, a second display is performed by the display module to indicate that the hydraulic guide rail is not installed in place on the mounting plate, and an installation adjustment prompt is output by the display module, and after installation adjustment, step S4 is performed again until the pre-installation coordinate is within the error of the reference coordinate.

[0015] As a further preferred technical solution of the above technical solution, step S5 further includes:

[0016] Step S6: (in working use) The image acquisition module periodically acquires images of the mounting plate on which the hydraulic guide rail is installed to obtain current image data of the hydraulic guide rail on the mounting plate and transmit the current image data to the processing module, so that the processing module obtains the current installation position of the hydraulic guide rail relative to the mounting plate and converts it into a current actual coordinate map, and the processing module compares the current actual coordinate map with the reference coordinate map to determine whether the current actual coordinate of the hydraulic guide rail relative to the mounting plate is within the error of the reference coordinate.

[0017] As a further preferred technical solution of the above technical solution, step S6 is specifically implemented as the following steps:

[0018] Step S6.1: If the current actual coordinate is within the error of the reference coordinate, a first display is performed by the display module to indicate that the hydraulic guide rail is currently installed in place on the mounting plate;

[0019] Step S6.2: If the pre-installation coordinate is not within the error of the reference coordinate, a second display is performed by the display module to indicate that the hydraulic guide rail is not currently installed in place on the mounting plate, and an adjustment prompt is output by the display module.

[0020] As a further preferred technical solution of the above technical solution, the hydraulic guide rail is installed on the mounting plate by a fixing screw, wherein:

[0021] In the fixed screw, the loose sensor is installed, the loose sensor detects the loose data of the current fixed screw in real time and periodically, and transmits the loose data to the processing module wirelessly, so that the processing module judges and obtains the loose condition of the current fixed screw, wherein

[0022] If the loose condition of the current fixed screw is within the normal range, the third display is performed through the display module;

[0023] If the loose condition of the current fixed screw is not within the normal range, the fourth display is performed through the display module (the application can also detect the loose sensor, and if the fixed screw is loose, it will also cause the installation position of the hydraulic guide rail to deviate).

[0024] As a further preferred technical solution of the above technical solution, the loose sensor is in a sleep state when not detecting, wherein:

[0025] If the loose amplitude of the fixed screw detected by the loose sensor in the sleep state is greater than the preset amplitude within a time period, the loose sensor is woken up and transmits the loose data to the processing module (the loose sensor is divided into a detection unit and a data processing unit, in order to reduce power consumption, the data processing unit is in a sleep state when not detecting, but the detection unit is in a state of always detecting, if the loose amplitude is less than the preset amplitude within a time period, the detection unit does not send the detected loose data to the data processing unit, so as to wait for the data processing unit to be woken up by the clock and actively detect, if the loose amplitude is greater than the preset amplitude within a time period, the data processing unit is woken up and passively receives the loose data for transmission after detection, for burst conditions).

[0033] Step S2: the processing module obtains mounting position data of the hydraulic guide rail on the mounting plate and marks mounting contour point positions of the hydraulic guide rail on the initial coordinate graph, so as to obtain a mounting reference coordinate graph of the hydraulic guide rail;

[0034] Step S3: the processing module produces a laser indication instruction according to the mounting reference coordinate graph and transmits the laser indication instruction to the laser scanning module, so that the laser scanning module emits an indication laser based on the mounting contour point positions on the mounting plate (convenient for mounting according to the indication laser);

[0035] After the hydraulic guide rail is pre-mounted to the mounting plate:

[0036] Step S4: an image acquisition module performs image acquisition on the mounting plate of the pre-mounted hydraulic guide rail, so as to obtain pre-mounting image data of the hydraulic guide rail on the mounting plate and transmit the pre-mounting image data to the processing module, so that the processing module obtains a pre-mounting position of the hydraulic guide rail on the mounting plate and converts the pre-mounting position into a pre-mounting coordinate graph;

[0037] Step S5: the processing module compares the pre-mounting coordinate graph with the reference coordinate graph, so as to determine whether the pre-mounting coordinate of the hydraulic guide rail relative to the mounting plate is within an error range of the reference coordinate.

[0038] Specifically, step S5 is implemented as the following steps:

[0039] Step S5.1: if the pre-mounting coordinate is within the error range of the reference coordinate, a first display is performed by a display module, indicating that the hydraulic guide rail is mounted in place on the mounting plate, and the pre-mounted hydraulic guide rail is formally mounted to the mounting plate, so that the mounting of the hydraulic guide rail is completed;

[0040] Step S5.2: if the pre-mounting coordinate is not within the error range of the reference coordinate, a second display is performed by the display module, indicating that the hydraulic guide rail is not mounted in place on the mounting plate, and an installation adjustment prompt is output by the display module, and after installation adjustment, step S4 is executed again until the pre-mounting coordinate is within the error range of the reference coordinate.

[0041] More specifically, step S5 further comprises:

[0042] Step S6: (in working use) the image acquisition module periodically acquires images of the mounting plate on which the hydraulic guide rail is mounted, to obtain current image data of the hydraulic guide rail on the mounting plate and transmit the current image data to the processing module, so that the processing module obtains the current mounting position of the hydraulic guide rail on the mounting plate and converts it into a current actual coordinate map, and the processing module compares the current actual coordinate map with the reference coordinate map to determine whether the current actual coordinate of the hydraulic guide rail relative to the mounting plate is within the error of the reference coordinate.

[0043] Further, step S6 is implemented as the following steps:

[0046] Further, the hydraulic guide rail is mounted on the mounting plate by a fixing screw, wherein:

[0047] The fixing screw is provided with a loosening sensor, which periodically detects loosening data of the current fixing screw in real time and transmits the loosening data to the processing module wirelessly, so that the processing module determines and obtains the loosening condition of the current fixing screw, wherein:

[0048] If the loosening condition of the current fixing screw is within the normal range, a third display is performed by the display module;

[0050] Preferably, the loosening sensor is in a sleep state when not in detection, wherein:

[0051] If the loosening sensor in the sleep state detects that the loosening amplitude of the fixing screw is greater than the preset amplitude within the time period, the loosening sensor is woken up and transmits the loosening data to the processing module (the loosening sensor is divided into a detection unit and a data processing unit, in order to reduce power consumption, the data processing unit is in a sleep state during detection, but the detection unit is in a state of always detecting, if the loosening amplitude is less than the preset amplitude within the time period, the detection unit does not send the detected loosening data to the data processing unit, and waits for the data processing unit to be woken up by the clock to actively detect, if the loosening amplitude is greater than the preset amplitude within the time period, the data processing unit is woken up and passively receives the loosening data for transmission, for a burst situation.
