Description

Technical Field

[0001] This utility model relates to the field of pipe fitting measurement technology, specifically an automatic pipe calibration mechanism. Background Technology

[0002] After the pipe fittings are manufactured, their inner diameter, outer diameter, thickness and other data need to be measured and calibrated. Currently, this is usually done manually using tools such as vernier calipers, which is quite troublesome.

[0003] To solve the above problems, there is a solution for an inner diameter measuring mechanism (announcement number CN222336257U). The positioning rod and the measuring rod are respectively placed against the left and right sides of the inner wall of the cap. Then, the reading can be directly taken according to the scale line and the pointer. The reading is the inner diameter of the cap, which can avoid calculation and make it more convenient to directly measure the inner diameter of the plastic cap.

[0004] However, when measuring the inner diameter of a pipe fitting, it is also necessary to measure the difference and average value of the inner diameter to determine whether the inner diameter of the pipe fitting is within the error range. The above method requires constant adjustment of the pipe fitting rotation when measuring the inner diameter of the pipe fitting, which is cumbersome and inefficient. Utility Model Content

[0005] The purpose of this invention is to provide an automatic tube calibration mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic pipe calibration mechanism, including a base, on which a servo motor is movably mounted, and a measuring head is mounted at the end of the servo motor. A power supply board is installed inside the measuring head, and two symmetrical laser transceivers are electrically connected to the surface of the power supply board. The inner diameter can be detected and measured automatically when the two laser transceivers are positioned on the diameter line of the pipe.

[0007] A flattener is installed on the right side of the base surface. The flattener horizontally clamps and covers the tube of the laser transceiver to prevent the tube from tilting and ensure higher accuracy of diameter measurement. The servo motor drives the laser transceiver to rotate and measure the circumference of the inner diameter of the tube, automatically realizing 360-degree measurement of the inner diameter of the tube.

[0008] A light-shielding ring is connected to the measuring head and is located on the side of the laser transceiver to prevent ambient light from interfering with the operation of the laser transceiver and reduce measurement errors.

[0009] Furthermore, an expansion joint is installed on the base, which is connected to a servo motor. The expansion joint pushes the laser transceiver to move horizontally inside the pipe. The expansion joint includes an electric cylinder and a slide rail. The slide rail is connected to a fixed seat through a slider. The servo motor is installed on the upper surface of the fixed seat, which can measure the inner diameter of the pipe at different positions, making it easy to check whether the inner diameter error of the pipe is within the allowable error range.

[0010] Furthermore, the power supply board is connected to a plug, the plug is connected to a signal line, the surface of the light-shielding ring is provided with a bayonet, the inner wall of the bayonet is provided with a retaining ball, and the signal line is placed inside the bayonet, which can prevent the signal line from blocking the laser transceiver.

[0011] Furthermore, the flattener includes a fixed frame and a cylinder connected to the fixed frame. An upper centering plate is installed at the lower end of the cylinder, and a lower centering plate connected to the base is provided below the upper centering plate. Both the upper and lower centering plates are V-shaped, which can clamp pipes of different diameters and has a wide range of applications.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) The pipe fitting is fitted onto the laser transceiver. The two laser transceivers measure the inner diameter of the pipe fitting through laser measurement, thereby realizing the automatic measurement of the inner diameter of the pipe fitting. The servo motor drives the laser transceiver to rotate one revolution, which can automatically measure the inner diameter of the pipe fitting at various points, resulting in high measurement efficiency.

[0014] (2) The electric cylinder drives the laser transceiver to move inside the pipe through the fixed base and servo motor, which can detect the inner diameter at multiple locations. The inner diameter detection results are more accurate and are helpful in judging whether the pipe meets the standards.

[0015] (3) The pipe is placed on the lower centering plate, and the cylinder drives the upper centering plate to move down and press down on the pipe, so that the pipe is placed horizontally. When measuring the inner diameter, the error caused by the tilt of the pipe is avoided, and the measurement result is less likely to be wrong.

[0016] (4) The light-transmitting plate protects the laser transceiver and prevents dirt and impurities from interfering with the operation of the laser transceiver. The signal line is locked inside the bayonet, and the ball locks the signal line to prevent it from becoming loose. This prevents the signal line from blocking the laser transceiver and will not affect the measurement results of the laser transceiver. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not 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 effort are within the protection scope of the present utility model.

[0023] Example:

[0024] Please see Figures 1-4 This utility model provides a technical solution: an automatic tube calibration mechanism, including a base 1, on which a servo motor 11 is movably mounted, and a measuring head 13 is mounted at the end of the servo motor 11. A power supply board 16 is installed inside the measuring head 13, and two vertically symmetrical laser transceivers 18 are electrically connected to the surface of the power supply board 16. The servo motor 11 drives the laser transceivers 18 to rotate in both directions, which can avoid the signal lines 12 from becoming tangled.

[0025] A flattener is installed on the right side of the base 1 surface. The flattener horizontally clamps and covers the tube of the laser transceiver 18 to ensure that the tube being measured is placed horizontally and to avoid measurement errors caused by the tube. The servo motor 11 drives the laser transceiver 18 to rotate and measure the circumference of the inner diameter of the tube. It can measure data such as the maximum inner diameter, minimum inner diameter, and average inner diameter of the tube.

[0026] A light-shielding ring 15 is connected to the measuring head 13. The light-shielding ring 15 is located on the side of the laser transceiver 18 and can block some ambient light from being received by the laser transceiver 18, thereby improving measurement stability and accuracy.

[0027] In this embodiment, a telescopic device is installed on the base 1. The telescopic device is connected to the servo motor 11. The telescopic device pushes the laser transceiver 18 to move horizontally inside the pipe, which can measure the inner diameter of the pipe over a certain distance and obtain more accurate results. The telescopic device can be a ball screw assembly, which can be selected according to the requirements.

[0028] In this embodiment, as Figure 1 As shown, the telescopic device includes an electric cylinder 7 and a slide rail 8. The slide rail 8 is connected to a fixed base 10 via a slider 9. The servo motor 11 is mounted on the upper surface of the fixed base 10. The electric cylinder 7 pushes the fixed base 10 to move, and the slider 9 moves along the slide rail 8 to improve the stability of the fixed base 10's movement and prevent the laser transceiver 18 from vibrating.

[0029] In this embodiment, as Figure 3 As shown, the surface of the measuring head 13 is provided with two light-emitting holes 20. A light-transmitting plate 19 is installed inside the light-emitting holes 20. The light-transmitting plate 19 protects the laser transceiver 18. The light-transmitting plate 19 is made of optical grade acrylic and will not affect the laser of the laser transceiver 18. The light-transmitting plate 19 can block dust and other impurities from adhering to the laser transceiver 18 and ensure that the laser transceiver 18 works normally.

[0030] In this embodiment, as Figure 1 As shown, the power supply board 16 is connected to a plug 17, and the plug 17 is connected to a signal line 12. The signal line 12 is connected to the laser ranging host. The laser ranging host is responsible for laser emission / reception timing control and distance calculation. The laser ranging host integrates an EEPROM or Flash chip to store calibration parameters, measurement history data and user configuration. The measurement results are displayed on the screen of the laser ranging host.

[0031] In this embodiment, as Figure 4 As shown, the surface of the light-shielding ring 15 is provided with a bayonet 14, and the inner wall of the bayonet 14 is provided with a ball 6. The signal line is placed inside the bayonet 14, which can prevent the signal line 12 from shaking and ensure that the signal line 12 will not block the laser transceiver 18.

[0032] In this embodiment, as Figure 1 and Figure 2 As shown, the flattener includes a fixed frame 3 and a cylinder 4 connected to the fixed frame 3. An upper centering plate 5 is installed at the lower end of the cylinder 4. A lower centering plate 2 connected to the base 1 is provided below the upper centering plate 5. Both the upper centering plate 5 and the lower centering plate 2 are V-shaped. When the pipe is placed on the lower centering plate 2, the pipe can be positioned to ensure that the laser transceiver 18 is on the diameter of the pipe, and the inner diameter of the pipe can be accurately measured.

[0033] Specifically, during use, the pipe fitting is placed on the lower centering plate 2, and the cylinder 4 drives the upper centering plate 5 to move down. While the upper centering plate 5 presses down on the pipe fitting, it makes the pipe fitting horizontal, thus achieving the purpose of automatic centering and positioning of the pipe fitting.

[0034] The electric cylinder 7 drives the servo motor 11 to move through the fixed base 10. The servo motor 11 drives the measuring head 13 and the laser transceiver 18 into the pipe. The emitting end of the laser transceiver 18 emits laser light, which is reflected by the pipe to the receiving end of the laser transceiver 18. By calculating the round-trip time of the laser beam and adding the distance between the two laser transceivers 18, the inner diameter data of the pipe is obtained.

[0035] The servo motor 11 drives the laser transceiver 18 to rotate one revolution, which can measure the inner diameter of the pipe more accurately and check whether the difference in the inner diameter of the pipe is within the error range. The electric cylinder 7 controls the laser transceiver 18 to continue to move into the pipe. The servo motor 11 drives the laser transceiver 18 to rotate one revolution in the opposite direction, which can measure the inner diameter of the pipe at different positions to ensure that the inner diameter of the pipe meets the standard.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
