[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.
[0022] Referring to Figure 1 、 Figure 2 and Figure 4 , Embodiment 1 provided by the present utility model
[0023] A workpiece flatness detection device includes a base 1. A plurality of installation grooves are formed in the upper side of the base 1. An air gauge 2 is fixedly installed in the plurality of installation grooves. An L-shaped through port is formed in the inner wall of the installation groove. An air delivery pipe 3 is fixedly installed at the air outlet end of the air gauge 2. The air delivery pipe 3 is fixedly installed in the L-shaped through port. A plurality of connection holes are formed in the inner wall of the installation groove. An air flow valve 5 is fixedly installed in each of the plurality of connection holes. One end of the air flow valve 5 is fixedly connected to the air inlet end of the air gauge 2. A fixing component is fixedly installed on the upper side of the base 1. The air gauge 2 uses a compressed air flow to measure the gap between a precision measuring hole (such as a nozzle) and a workpiece. Since the flow rate and pressure of air are proportional to the gap, and the flow rate and pressure are inversely proportional, when the gap increases, the air flow rate will increase, and the air pressure will decrease; when the gap decreases, the air flow rate will decrease, and the air pressure will increase. Thus, a relationship curve of the air flow rate and pressure values with respect to the gap between the nozzle and the measured surface can be plotted. In this device, the test port of the air gauge 2 is connected to a tubular workpiece. By supplying air to the air gauge 2 to fill the cavity of the entire tubular workpiece, if the cavity is uneven, it will cause fluctuations in the pressure and flow rate curves when the air passes through, indicating that the inner wall of the workpiece lacks flatness, thereby detecting whether the inner wall of the workpiece is flat, the air flow valve 5.
[0024] As Figure 4 shown, a sealing rubber sleeve 4 is fixedly installed at one end of the air delivery pipe 3. The sealing rubber sleeve 4 can hermetically wrap the tubular workpiece to connect it to the air delivery pipe 3.
[0025] As Figure 1 shown, a data control panel 6 is fixedly installed on one side of the base 1. The data control panel 6 is electrically connected to a plurality of air gauges 2. The data control panel 6 can process and collect the data collected by the air gauges 2 and send and upload it to a cloud server or a data center designated by the customer, avoiding data loss or data confusion during data transfer, which affects the final judgment of engineers. At the same time, the data control panel 6 also has the function of receiving customized configuration information to facilitate better setting of test thresholds.
[0026] When the device is in use, first start the air gauge 2, and inject air into the air gauge 2 through the air flow valve 5. Adjust the air flow valve 5 to make the air pressure stable within a certain range. Then set the test threshold through the data control panel 6. Finally, connect the tubular test workpiece to be detected to the air delivery pipe 3 through the sealing rubber sleeve 4 and start the detection. The air flow valve 5 transmits the gas into the air gauge 2 and enters the workpiece through the air delivery pipe 3. At this time, the air gauge 2 monitors the gas flow rate and sends the flow rate data to the data control panel 6 for analysis. If the gas flow rate is lower or higher than the threshold area, the flatness of the workpiece is poor. If it is close to the preset value, it means that the flatness of the workpiece is qualified.

The second-level silica gel plate 16 has the same function as the first-level silica gel plate 11. When the two second-level silica gel plates 16 and the two first-level silica gel plates 11 are both attached to the surface of the sealing rubber sleeve 4, the sealing rubber sleeve 4 can be squeezed to prevent air leakage.
[0030] As Figure 3 shown, an adjustment groove is formed on one side of the mounting bracket 7, and two adjustment blocks 8 are slidably installed in the adjustment groove. The two adjustment blocks 8 are fixedly connected to the two sliding rods 9 correspondingly. A rotating hole is formed on one side of the mounting bracket 7, and a bidirectional lead screw 12 is rotatably installed in the rotating hole. The two adjustment blocks 8 are both screwed onto the threaded areas on the surface of the bidirectional lead screw 12.
[0031] As Figure 3 shown, a driving motor 13 is fixedly installed on one side of the mounting bracket 7, and the output end of the driving motor 13 is coaxially and fixedly connected to one end of the bidirectional lead screw 12. The driving motor 13 is a servo motor and can rotate forward and backward.
[0032] The driving motor 13 drives the bidirectional lead screw 12 to rotate. The bidirectional lead screw 12 drives two adjusting blocks 8 to approach each other. The two adjusting blocks 8 respectively drive two sliding rods 9 to approach each other. The two sliding rods 9 respectively drive a plurality of spring rods 10 to approach each other. The plurality of spring rods 10 respectively drive two first silicone plates 11 to approach each other, so that the two first silicone plates 11 are attached to the surface of the sealing rubber sleeve 4. When moving further, while squeezing the spring rods 10, it drives the moving plates 14 to approach each other. The moving plates 14 respectively drive the rotating rods 15 to move. The rotating rods 15 drive the second silicone plates 16 to move, so that the two second silicone plates 16 approach each other perpendicular to the movement direction of the two first silicone plates 11, thereby squeezing and fixing the sealing strip, and further achieving the extrusion and sealing of the sealing strip, preventing gas leakage during the gas detection process, affecting the detection result, and improving the detection accuracy.
