Description

Technical Field

[0001] The utility model relates to the technical field of roughness meters, in particular to a shockproof laser roughness meter with a flat bottom surface. Background Art

[0002] The roughness meter uses the needle tracing method, also known as the stylus method. When the stylus is gently scratched directly on the measured surface of the workpiece, the stylus will move up and down in a direction perpendicular to the measured surface due to the ups and downs of the measured surface profile. This movement is amplified by an electronic device, and then the data or graphics related to the roughness are output through a zero indicator or other output device. The surface roughness measuring instrument using the needle tracing principle consists of a sensor, a driver, a zero indicator, a recorder and an inductive sensor. The inductive sensor is one of the main components of the profile meter. A diamond stylus is installed at one end of the sensor rod. The curvature radius r of the stylus is very small. During measurement, the stylus is placed on the workpiece and in vertical contact with the measured surface. The driver is used to drag the sensor at a certain speed.

[0003] Due to the undulating peaks and valleys of the measured surface, the stylus will move up and down when sliding on the measured surface. This movement causes the magnetic core to move up and down synchronously through the fulcrum, thereby changing the inductance of the two differential inductor coils surrounding the magnetic core; the sensor coil and the measuring circuit are directly connected to the balanced bridge, and the change in the coil inductance causes the bridge to lose balance, so it outputs a signal proportional to the up and down displacement of the stylus. After the electronic device amplifies this weak change in electricity and performs phase-sensitive detection, a signal that can represent the size and direction of the stylus displacement is obtained.

[0004] After that, the signal is divided into three paths: one path is added to the zero indicator to indicate the position of the stylus, one path is input to the DC power amplifier, and after amplification, it drives the recorder to record; the other path is amplified by filtering and averaging amplifier, and then enters the integral calculator for integral calculation, and the surface roughness Ra value can be directly read from the indicator.

[0005] Patent No. CN202321258276.0 discloses a roughness meter height adjustment structure, which cooperates with a limit rod, a bearing sleeve, a lead screw and a motor, so that when the operator uses it, the electric telescopic rod can be controlled to limit the roughness meter body, and then the operator can place the part to be measured in the middle position of the two clamping blocks of the clamping assembly. Then the operator can start the motor, and the motor drives the mounting frame to move on the lead screw, so that the height of the roughness meter body can be adjusted, which is convenient for the operator to measure the roughness of the part measuring surface. However, this structure has the following problems: First, it is impossible to adjust the position of the object being tested front, back, left and right, and the scope of application is small. Secondly, the workpiece stability is not high and the working process has a high risk factor. Utility Model Content

The line system protection cover 2 collects and gathers the internal lines of the entire detector, and can ensure the overall aesthetics while protecting the lines. Moreover, because the lines are gathered in the line system protection cover 2, through holes 21 are opened at the lower ends of the left and right sides of the protection cover 2 to realize air circulation, and then the ventilation fan 22 is used to ensure the internal heat dissipation effect of the line system protection cover 2, extend the service life of the device, and ensure a high overall safety factor. The ventilation fan 22 can use the ventilation holes 21 opened on the left and right sides to realize air convection to rotate, and can also be set to rotate with a micro motor using a rotating shaft, and the set micro motor circuit can be placed in the line system protection cover 2, which is beautiful and generous.

[0031] Furthermore, the vertical slider 8 includes a slider base 81, a round shaft rod 82 is provided at the inner center position of the upper end of the slider base 81, a sliding convex block 83 is slidably connected to the round shaft rod 82, a rectangular limiting hole 84 is provided at the upper end of the sliding convex block 83, a limiting plate 85 is passed through the rectangular limiting hole 84, and the front and rear ends of the limiting plate 85 are fixedly connected to the upper sides of the front and rear ends of the slider base 81.

The principle is simple and the operation is stable.

[0034] Furthermore, the laser roughness detector 63 includes an instrument body 631, and a contact pin 632 is provided at the lower end of the instrument body 631. The lower end of the contact pin 632 is in a truncated cone shape.
