Description

TECHNICAL FIELD

[0001] The utility model relates to industrial detection technical field especially, relates to a wave pearl screw assembly height detection device. BACKGROUND

[0002] The existing wave pearl screw assembly height detection device usually adopts non-contact sensor technology, such as laser sensor or photoelectric sensor, judges the height by accurately measuring the distance between the top of wave pearl screw and the reference surface. The device usually includes a sensor, a control system and a mechanical platform. The sensor scans the top of the wave pearl screw, obtains the height data and transmits it to the control system, and the control system is combined with PLC to process and judge the data. If the height does not meet the requirements, the system will issue an alarm or automatically adjust the assembly process. The advantages of the device are that it can realize fast and accurate automatic detection, reduce human error and be suitable for wave pearl screw height detection in large-scale production lines.

[0003] The existing device may not be cleaned properly during long-term use, which may cause dust and oil film to pollute the sensor, affect the measurement accuracy of the sensor, and lead to inaccurate data, thereby affecting the detection result of the wave pearl screw height. Long-term accumulation of pollutants may also cause internal wear and tear of mechanical parts, so the utility model adds a cleaning mechanism on the top of the device to clean the equipment to a certain extent and avoid errors in subsequent work. At the same time, the clamping device of the existing workbench may not be accurate, causing the wave pearl screw to shift or shake during measurement and adjustment, thereby affecting the detection accuracy. Therefore, the utility model sets up a clamping structure with a laser sensor to detect the position of the wave pearl screw in real time and ensure that the wave pearl screw is always in the correct detection position, avoiding height deviation caused by inaccurate clamping.

[0004] Therefore, we propose a wave pearl screw assembly height detection device. Utility model content

[0005] The purpose of this invention is to address the shortcomings of existing technologies. During long-term use, existing devices may experience incomplete cleaning, leading to the accumulation of dust, oil film, and other contaminants. This affects the measurement accuracy of the sensor, resulting in inaccurate data and consequently impacting the detection results of the ball screw height. Furthermore, long-term contaminant accumulation can cause wear and malfunction of mechanical parts. To solve this problem, this invention adds a cleaning mechanism to one side of the device, enabling regular cleaning and preventing errors. Meanwhile, the clamping device of existing worktables may lack sufficient precision, causing displacement or vibration of the ball screw during measurement and adjustment, thus affecting detection accuracy. Therefore, this invention designs a clamping structure with a laser sensor to monitor the position of the ball screw in real time, ensuring it is always in the correct detection position and avoiding height deviations caused by inaccurate clamping.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

The second link is rotatably connected to a support rod on the end away from the sliding collar. The support rod is slidably connected to the top of the support frame. A clamping block is fixedly installed on the end of the support rod away from the support frame. Threaded grooves are opened on the corresponding sides of the two clamping blocks. A laser sensor is fixedly installed on the top of the clamping blocks.
