[0030] The present application provides a verticality calibration system, which mainly includes: a workbench 1, a housing 2, a slide bar 3, a slider 4, a drive device 5 and a distance measurement component 6.

[0031] The workbench 1 is used to place the workpiece to be inspected. The housing 2 is arranged on the upper part of the workbench 1, and the housing 2 is provided with a placement portion for placing the slide bar 3, the slider 4, the drive device 5 and the distance measuring component 6. The distance measuring component 6 is connected to an external control device. The slide bar 3 is vertically arranged on the placement portion, the slider 4 is slidably installed on the slide bar 3, and the measuring device or the dial indicator is arranged in the mounting hole of the slider 4.

[0032] The driving device 5 is arranged at the placement part, and the driving device 5 is used to drive the slider 4 to slide along the slide rod 3. The distance measuring component 6 is arranged at the placement part of the slider 4 and the housing 2, and the distance measuring component 6 is used to detect the displacement of the slider 4 movement, and the distance measuring component 6 is connected to the external control device.

[0033] This application optimizes the scheme of the traditional verticality calibration instrument. The slider 4 is directly or indirectly installed on the slide bar 3 through a clamp, and a distance measuring component 6 is set on the slider 4 and the placement part, and the movement displacement of the slider 4 is detected by the distance measuring component 6. The distance measuring component 6 is connected to the external control device. The operator controls the equipment calibration process through the computer software. It only needs to manually place the workpiece to be inspected at the specified position of the workbench 1. The subsequent movement of the slide bar 3 and the stop operation of the fixed point position of the movement are completed by the terminal software, avoiding the errors caused by manual button control of the motor and manual reading of the position. After the calibration is completed, data processing and calculation are automatically performed. The built-in software of the terminal device opens the port at the same time, which can be connected to the intelligent digital management system to realize the functions of one-click upload and data access at any time. The built-in software of the terminal device controls the driving device 5. The driving device 5 moves the probe to move on the slide bar 3. The system collects data such as the torsion spring table and grating value of the distance measuring component 6, automatically calculates the error and prints the report.

[0034] It should be noted that regarding the software automation control solution, please refer to the existing technology, which will not be elaborated in this article.

[0035] In a specific embodiment, two fine-tuning devices 7 for adjusting the lateral position of the workpiece to be inspected on the workbench 1 are provided on the rib of the workbench 1 .

[0036] Each fine-tuning device 7 includes a nut, a clamp and an adjusting screw. The clamp is used to clamp the nut to the flange, and the adjusting screw is threadedly connected to the nut. The nut can also be directly clamped and fixed to the flange. By adjusting the two screws synchronously or step by step, the end of the adjusting screw is used to push the workpiece to be inspected to achieve lateral adjustment of the position of the adjusting screw. This adjustment structure has a simple structure, convenient and fast adjustment, and efficient adjustment.

[0037] An adjustable support 8 is provided at the bottom of the workbench 1. The adjustable support 8 includes an adjusting nut and an adjusting stud. The adjusting nut is fixedly mounted on the bottom surface of the workbench 1, and the adjusting stud is threadedly connected to the adjusting nut. When the height of the workbench 1 needs to be adjusted, the workbench 1 can be raised and lowered by rotating the adjusting stud and using a measuring ruler or measuring instrument. The adjustment structure is simple, and the operation is convenient and efficient.

[0038] There are three adjustable supports 8 distributed in a triangular shape at the bottom of the workbench 1 , thereby forming a triangular support structure, which can improve the stability of the support of the workbench 1 .

[0039] The distance measuring assembly 6 includes a baffle plate arranged on the side wall of the slider 4 and a distance meter arranged on the placement portion. The baffle plate can move synchronously with the slider 4. The distance meter can sense the position of the baffle plate in real time. When it is detected that the baffle plate moves to a preset position, the external control device controls the driving device 5 to stop running. The distance meter of the present application can be a laser distance meter or an infrared distance meter.

[0040] The control device specifically includes a motor drive module connected to the distance measuring component 6 and a terminal device connected to the motor drive module. The motor drive module connects the distance measuring component 6 and the terminal device, and sends a drive signal to the drive device to control the drive device to run and stop.

[0041] In another specific embodiment, the distance measuring component 6 includes a grating counting head 61 and a scale grating 62. The grating counting head 61 is arranged on the side wall of the slider 4, and the scale grating 62 is arranged on the placement portion. The grating counting head 61 is used to detect the displacement corresponding to the scale grating 62, and the grating counting head 61 is connected to an external control device to transmit the detected displacement data corresponding to the scale grating 62 to the motor driving module, and the motor driving module controls the motor and other driving devices 5 to run or stop running.

[0042] In this embodiment, since the measurement output signal of the grating ruler is a digital pulse, it has a large detection range, high detection accuracy and fast response speed. The automatic reading and positioning of the movement position of the slider 4 is achieved by combining a high-precision grating with an external control system.

[0043] In order to prevent the slider 4 from overtravel movement, limit blocks 9 can be respectively provided at the upper and lower parts of the slide bar 3 , and the slider 4 is blocked by the upper and lower limit blocks 9 to ensure that the slider 4 moves within a predetermined range.

[0044] Regarding the driving method between the driving device 5 and the slider 4 , in a specific implementation manner, the driving end of the driving device 5 is connected to a rotating wheel, a rope body is wound around the rotating wheel, and the rope body is connected to the slider 4 .

[0045] When the driving device 5 rotates in a certain direction, the driving device 5 lowers the rope body, and the slider 4 slides downward along the slide bar 3 due to gravity. By controlling the rotation angle of the driving device 5, the movement displacement of the slider 4 is controlled.

[0046] When the driving device 5 rotates in the opposite direction, the driving device 5 pulls the rope body to rise, and the rope body pulls the slider 4 to overcome gravity and move upward along the slide bar 3.

[0047] The driving device 5 drives the slider 4 to rise and fall through the rotating wheel and the rope body, which can reduce the vibration and high speed caused by the direct action of the driving force and improve the stability of the movement. In addition, this transmission method has little modification to the traditional verticality tester and is low in cost.

[0048] The driving device 5 can also directly drive the slide bar 3 to rotate and drive the slider 4 threadedly connected to the slide bar 3 to achieve lifting along the slide bar 3. It has a simple structure, compact layout, and does not occupy space.

[0049] The present application improves the traditional verticality tester by installing a distance measuring component 6 on the slider 4 and in the housing 2, and the distance measuring component 6 is connected to an external control device to realize the intelligent control of the lifting motion of the slider 4, replacing the current structure that can only control the slider 4 to rise by buttons and rely on the slider 4's own gravity to fall, thereby improving the control accuracy. In addition, the present application realizes motion control and data acquisition through a built-in program in the external control device, achieving the requirements of automatic data reading, semi-automatic verification and fully automatic calculation, making the verification process more intelligent.

[0050] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core idea of ​​the present application.
