Description

Technical Field

[0001] This utility model relates to the field of industrial parts processing technology, specifically to a non-contact dimensional measuring device for industrial parts. Background Technology

[0002] Industrial parts processing is one of the core links in manufacturing. It involves transforming raw materials into parts that meet design requirements through processes such as machining, forming, and heat treatment. Turning uses a lathe to rotate the workpiece and cuts it with a cutting tool to form rotating parts such as cylinders and cones. Milling uses multi-edged cutting tools to rotate and process planes, grooves, or complex curved surfaces. Drilling uses a drill bit to process round holes. Grinding is a high-precision surface machining process that can achieve micron-level tolerances. Non-contact dimensional measurement devices used for industrial parts typically utilize technologies such as optics, lasers, vision, or ultrasound to achieve high-precision and high-efficiency dimensional inspection. They are suitable for quality control, reverse engineering, or production process monitoring.

[0003] Some existing non-contact dimensional measurement devices for industrial parts first place the workpiece on the upper end of the machine table when performing non-contact dimensional measurement of industrial parts. Then, the angle position of the industrial camera is moved by the motor and the lead screw. The industrial camera then takes an image of the part through a high-resolution camera, and the size is calculated by combining the image processing algorithm.

[0004] Existing non-contact dimensional measurement devices for industrial parts have the following problems: when performing non-contact dimensional measurement on industrial parts, a single industrial camera sensor is used as the main component, which has limited functionality and is difficult to handle complex curved surfaces or three-dimensional dimensions. It is necessary to switch between different devices to complete multi-dimensional measurements, which is time-consuming and labor-intensive. Therefore, we propose a non-contact dimensional measurement device for industrial parts. Utility Model Content

[0010] Furthermore, the secondary fixing assembly also includes trapezoidal blocks, rollers, and U-shaped blocks.

Rollers are rotatably connected to the lower ends of the U-shaped blocks, and the outer surfaces of the rollers are slidably connected to the inclined surfaces of the vertically adjacent trapezoidal blocks to provide compression.

[0011] Furthermore, the secondary fixing assembly also includes a pull rod, a plug strip, and a fixing strip.

[0016] Insert the mounting platform into the mounting base and use magnets one and two for magnetic positioning to achieve initial installation. Press the connector strip, and the connector strip, through the pull rod and U-shaped block, causes the roller to press against the trapezoidal block. The trapezoidal block pushes the connector rod into the connector hole. Rotate the connector strip under the fixing strip to lock it in place, thus completing the installation. By moving the connector strip to disengage from the fixing strip, the trapezoidal block is released from pressure, the spring returns, and the connector rod is pulled out of the connector hole, allowing the mounting platform to detach and be disassembled. When performing non-contact dimensional measurement of industrial parts, the sensor can be quickly replaced to measure complex curved surfaces or three-dimensional dimensions without switching between different devices to complete multi-dimensional measurements, reducing manpower waste and time costs.

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.

[0024] Please see Figure 1-5This embodiment provides a technical solution: a non-contact dimensional measuring device for industrial parts, including a housing 1. The upper end of the housing 1 is provided with two symmetrically arranged electric slide rails 2. An electric slide rail 4 is provided between the sliding seats of the two electric slide rails 2 via a support rod 3. An adjusting platform 6 is provided at the front end of the sliding seat of the electric slide rail 4 via a support seat 5. An adjusting rod 7 is slidably connected inside the adjusting platform 6. A rotating measuring seat 8 is provided at the lower end of the adjusting rod 7. (The rotating measuring seat 8 is a commonly used two-axis automatic rotating seat in the prior art, including a first micro servo motor for horizontal circumferential adjustment, a rotating shaft driven by the first micro servo motor through a coupling, and a plane adjusting seat on the rotating shaft; a second micro servo motor for vertical circumferential adjustment; and an output of the second micro servo motor.) The device consists of a first gear on the shaft and a second gear on the side seat. The side seat is rotatably connected to the plane adjustment seat via a rotating shaft. The second gear is fixedly sleeved on the rotating shaft. A micro servo motor is mounted on the plane adjustment seat (the first and second gears are meshed together). It also includes a quick loading and unloading mechanism 9. A microcontroller 17 is located at the right end of the chassis 1. The input terminal of the microcontroller 17 is electrically connected to an external power supply. The laser displacement sensor probe 10 is bidirectionally electrically connected to the microcontroller 17. The input terminals of the electric slide rail 1 2, the electric slide rail 2 4, and the rotary measuring seat 8 are all electrically connected to the output terminal of the microcontroller 17. A drawer 11 is slidably connected to the left end of the chassis 1. Two mounting platforms 904 are also placed inside the drawer 11. The front end of the mounting platform 904 located on the left side inside the drawer 11 is equipped with a high-resolution... An industrial camera 12 is located inside drawer 11. A structured light 3D scanning head 13 is mounted on the front of the mounting platform 904 on the right side of the platform. Both the high-resolution industrial camera 12 and the structured light 3D scanning head 13 are bidirectionally electrically connected to the microcontroller 17. A motor 16 is mounted on the upper end of the adjustment platform 6. A lead screw 14 is fixedly connected to the lower end of the output shaft of the motor 16. The lower end of the lead screw 14 is threadedly connected to the threaded hole in the middle of the adjustment rod 7. The input ends of the motor 16 are electrically connected to the output ends of the microcontroller 17. A bellows 15 is fixedly connected between the top wall of the adjustment platform 6 and the upper end of the adjustment rod 7. The bellows 15 is sleeved on the outside of the lead screw 14. When performing non-contact dimensional measurement of industrial parts, the workpiece is placed on the upper end of the chassis 1. The electric slide rail 12 is controlled by the microcontroller 17. The second movable slide rail 4 operates, and the lead screw shaft inside the first electric slide rail 2 and the second electric slide rail 4 rotates under the drive of a servo motor, etc. Since both the lead screw shaft and the nut have helical grooves with arc-shaped surfaces, they fit together to form a raceway, and the balls roll in the raceway. When the lead screw shaft rotates, the balls roll between the lead screw shaft and the nut, thereby driving the nut to move linearly along the lead screw shaft, realizing the function of converting rotational motion into linear motion. The first electric slide rail 2 can drive the support rod 3 to move longitudinally, and the support base 5 and the adjustment table 6 can slide laterally on the second electric slide rail 4. The two work together to enable the high-resolution industrial camera 12, the structured light 3D scanning head 13, or the laser displacement sensor probe 10 to be accurately positioned in the horizontal plane. Then, through the control of the microcontroller 17, the motor 16 operates.The output shaft of motor 16 drives the lead screw 14 to rotate, and the lead screw 14 drives the threaded adjusting rod 7 to move up and down, realizing vertical height adjustment. The bellows 15 is sleeved on the lead screw to prevent dust from entering and ensure transmission accuracy. The rotary measuring base 8 is a fully automatic rotary measuring base. Through the control of the microcontroller 17, the micro servo motor 1 inside the rotary measuring base 8 operates, driving the rotating shaft to rotate through the coupling, thereby driving the horizontal rotation of the plane adjusting base and the side base. Then, through the operation of the micro servo motor 2, the first gear inside drives the meshing transmission of the second gear on the side base, driving the measuring base to rotate vertically. It is driven by the electrical signal of the microcontroller 17 to achieve precise angle control of the mounting base 901. When using the laser displacement sensor probe 10, through the control of the microcontroller 17, the laser displacement sensor probe 10 operates. The laser displacement sensor probe 10 emits a laser beam to the surface of the part, receives the reflected light, and calculates the beam. The time of flight or phase difference determines the distance between the probe and the part surface, enabling dimensional measurement. When using a high-resolution industrial camera 12, it is controlled by a microcontroller 17. The high-resolution industrial camera 12 captures two-dimensional images of the workpiece, and image processing algorithms analyze the part's dimensions, aperture, notches, and other features. When using a structured light 3D scanning head 13, it is controlled by the microcontroller 17. The structured light 3D scanning head 13 projects a specific pattern of structured light onto the part surface, and the camera captures the deformed light patterns. The three-dimensional shape of the part is reconstructed using triangulation principles. The laser displacement sensor probe 10, high-resolution industrial camera 12, and structured light 3D scanning head 13 transmit detection data to the microcontroller 17, which performs integrated analysis. After measurement, all measuring heads are placed inside drawer 11.

[0025] The quick-loading and unloading mechanism 9 includes a mounting base 901, a first magnet 902, a second magnet 903, a mounting platform 904, and a secondary fixing assembly. The mounting base 901 is located at the front end of the rotating measuring base 8. The mounting platform 904 is inserted into the mounting base 901. A laser displacement sensor probe 10 is located at the front end of the mounting platform 904. The first magnet 902 is located on the rear wall of the mounting base 901, and the second magnet 903 is located at the rear end of the mounting platform 904. The first magnet 902 and the second magnet 903 are installed together. The secondary fixing assembly is used to fix the mounting platform 904 and the mounting base 901. The secondary fixing assembly includes an adjusting seat 905, a insertion hole 906, an insertion rod 907, a spring 908, and a sliding plate 909. The adjusting seats 905 are respectively located on the left and right sides of the mounting base 901. At the end of the adjustment seat 905, sliding plates 909 are slidably connected to the bottom wall. Insertion rods 907 are fixedly connected to opposite ends of the sliding plates 909. Insertion holes 906 are provided at both ends of the mounting platform 904. Insertion rods 907 are fitted into adjacent insertion holes 906. Springs 908 are sleeved on the outer sides of the insertion rods 907 between the inner surfaces of the sliding plates 909 and the inner walls of the adjacent adjustment seats 905. The secondary fixing assembly also includes trapezoidal blocks 910, rollers 911, and U-shaped blocks 912. Trapezoidal blocks 910 are fixedly connected to opposite outer surfaces of the sliding plates 909. U-shaped blocks 912 are slidably connected to the upper side of the interior of the adjustment seat 905. Rollers 911 are rotatably connected to the lower ends of the U-shaped blocks 912. 1. The outer surface of the roller 911 is slidably connected to the inclined surface of the vertically adjacent trapezoidal block 910. The secondary fixing assembly also includes a pull rod 913, a plug strip 914, and a fixing strip 915. The upper end of the U-shaped block 912 is fixedly connected to the pull rod 913, and the upper end of the pull rod 913 is rotatably connected to the plug strip 914. The upper end of the adjusting seat 905 is provided with a fixing strip 915. The plug strip 914 is installed in conjunction with the top wall of the vertically adjacent fixing strip 915. Then, the drawer 11 is slid out, and the required probe is taken out. Then, the mounting platform 904 is inserted into the mounting base 901. The magnet 902 on the rear wall of the mounting base 901 and the magnet 903 at the rear end of the mounting platform 904 attract each other, completing the initial fixing. When inserted, the plugs at the left and right ends of the mounting platform 904... Align the connector hole 906 with the insertion rod 907 inside the adjusting seat 905. Then, press down on the insertion strip 914. The insertion strip 914 will drive the pull rod 913 downward, which in turn will drive the roller 911 downward through the U-shaped block 912. The outer surface of the roller 911 will slide from the highest point of the inclined surface of the trapezoidal block 910 to the lowest point of the inclined surface of the trapezoidal block 910, thereby pressing the trapezoidal blocks 910 to move towards each other. The trapezoidal blocks 910 will then drive the insertion rod 907 to insert into the connector hole 906 through the sliding plate 909. When the sliding plate 909 moves, it will compress the spring 908. Then, fix the mounting platform 904. After fixing, rotate the insertion strip 914 until it is rotated to the lower end of the fixing strip 915 to fix the pull rod 913.When replacement is needed, move the connector strip 914 to disengage it from the locking strip 915. This will cause the pull rod 913 to disengage from the obstruction, and the trapezoidal block 910 to release from pressure. The sliding plate 909, under the return of the spring 908, will then disengage the connector rod 907 from the connector hole 906. Finally, remove the mounting platform 904 from the mounting base 901 to complete the disassembly.

[0026] The working principle of the non-contact dimensional measuring device for industrial parts provided by this utility model is as follows: When performing non-contact dimensional measurement on industrial parts, the workpiece is placed on the upper end of the housing 1. Through the control of the microcontroller 17, the electric slide rail 12 and electric slide rail 24 operate. The lead screw shafts inside the electric slide rail 12 and electric slide rail 24 rotate under the drive of servo motors, etc. Since both the lead screw shaft and the nut have arc-shaped spiral grooves, they form a raceway. The balls roll within the raceway. When the lead screw shaft rotates, the balls roll between the lead screw shaft and the nut, thereby driving the nut to move linearly along the lead screw shaft, realizing the function of converting rotational motion into linear motion. The electric slide rail 12 can drive the support rod 3 to move longitudinally, and the support base 5 and adjustment platform 6... Lateral sliding is achieved on the electric slide rail 4. The two work together to precisely position the high-resolution industrial camera 12, structured light 3D scanning head 13, or laser displacement sensor probe 10 in the horizontal plane. Then, controlled by the microcontroller 17, the motor 16 operates. The output shaft of the motor 16 drives the lead screw 14 to rotate, and the lead screw 14 drives the threaded adjusting rod 7 to move up and down, achieving vertical height adjustment. A bellows 15 is fitted over the lead screw 14 to prevent dust from entering and ensure transmission accuracy. The rotary measuring seat 8 is a fully automatic rotary measuring seat. Controlled by the microcontroller 17, the first micro servo motor inside the rotary measuring seat 8 operates, driving the rotating shaft to rotate via a coupling, thus achieving horizontal rotation of the plane adjusting seat and the side seat. Then, the second micro servo motor operates... The first gear inside drives the second gear on the side seat to mesh and rotate the measuring base vertically. Driven by electrical signals from the microcontroller 17, it achieves precise angle control of the mounting base 901. Next, drawer 11 is slid out, and the required probe structure is taken out. Depending on the measurement requirements, a high-resolution industrial camera 12, a structured light 3D scanning head 13, or a laser displacement sensor probe 10 is replaced. First, the mounting platform 904 is inserted into the mounting base 901. Magnet 902 on the rear wall of the mounting base 901 attracts magnet 903 at the rear end of the mounting platform 904, completing the initial fixation. During insertion, the insertion holes 906 at both ends of the mounting platform 904 are aligned with the insertion rods 907 inside the adjusting seat 905. Then, the insertion strips 914 are pressed downwards respectively. The insertion strip 914 will drive the pull rod 913 downward, which in turn will drive the roller 911 downward through the U-shaped block 912. This causes the outer surface of the roller 911 to slide from the highest point of the inclined plane of the trapezoidal block 910 to the lowest point, thus pressing the trapezoidal blocks 910 to move towards each other. The trapezoidal blocks 910 will then drive the insertion rod 907 to insert into the insertion hole 906 via the sliding plate 909. As the sliding plate 909 moves, it will compress the spring 908, thereby fixing the mounting platform 904. After fixing, the insertion strip 914 will be rotated until it reaches the lower end of the fixing strip 915 to fix the pull rod 913. When replacement is needed, the insertion strip 914 will be moved to disengage from the fixing strip 915.Then, the pull rod 913 will disengage from the obstruction, and the trapezoidal block 910 will disengage from the compression. The sliding plate 909, under the rebound of the spring 908, will cause the insertion rod 907 to disengage from the insertion hole 906. Next, the mounting platform 904 will be removed from the mounting base 901, completing the disassembly. When using the laser displacement sensor probe 10, it operates under the control of the microcontroller 17. The laser displacement sensor probe 10 emits a laser beam to the surface of the part, receives the reflected light, and calculates the beam's flight time or phase difference to determine the distance between the probe and the part's surface, thereby performing dimensional measurements. When using the high-resolution industrial camera 12, it operates under the control of the microcontroller 17. A high-resolution industrial camera 12 captures two-dimensional images of the workpiece by photographing it. Image processing algorithms analyze the part's dimensions, apertures, notches, and other features. When a structured light 3D scanning head 13 is used, it is controlled by a microcontroller 17. The structured light 3D scanning head 13 projects a specific pattern of structured light onto the part's surface. The camera captures the deformed light patterns and reconstructs the part's three-dimensional shape using triangulation principles. The laser displacement sensor probe 10, the high-resolution industrial camera 12, and the structured light 3D scanning head 13 transmit the detection data to the microcontroller 17, which performs integrated analysis. After measurement, all measuring heads are placed inside the drawer 11.

[0027] It is worth noting that in the above embodiments, the electric slide rail 1-2, electric slide rail 2-4, rotary measuring base 8, laser displacement sensor probe 10, high-resolution industrial camera 12, structured light 3D scanning head 13, and motor 16 disclosed in the embodiments can all use THKSRG15A ball screw type linear guide rails for electric slide rail 1-2 and electric slide rail 2-4, the laser displacement sensor probe 10 can be LK-G30, the high-resolution industrial camera 12 can be Basleraceac A2040-90um, the structured light 3D scanning head 13 can be Zivi3DOne M10, the motor 16 can be YS8024, the rotary measuring base 8 can be AT10 fully automatic rotary measuring base, and the single-chip microcomputer 17 controls the operation of electric slide rail 1-2, electric slide rail 2-4, rotary measuring base 8, laser displacement sensor probe 10, high-resolution industrial camera 12, structured light 3D scanning head 13, and motor 16 using methods commonly used in the prior art.
