Detailed implementation mode

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figure 1 - Figure 8 , the present invention provides a technical solution: a metal casting size measuring instrument with rapid calibration, including a mounting shell 1, a light-shielding cloth 2 is fixedly connected to one side surface of the mounting shell 1, a storage board 3 is attached to the lower surface of the light-shielding cloth 2, a storage guide rail 4 is attached to one side surface of the storage board 3, a control panel 5 is fixedly connected to one side surface of the mounting shell 1, an infrared measurement mechanism 6 is arranged on the inner wall surface of the mounting shell 1, a calibration shell 7 is fixedly connected to one side surface of the mounting shell 1, and a casting detection mechanism 8 is arranged on one side surface of the calibration shell 7; The infrared measurement mechanism 6 includes a measurement guide rail 601, a driven roller 602, a measurement base 603, a measurement motor 604, a drive belt 605, a drive roller 606, a snap female part 607, a snap male part 608, a limit spring 609, a release rod 610, a limit plate 611, an infrared base 612, and an infrared reactor 613. The inner wall surface of the installation shell 1 is fixedly connected with the measurement guide rail 601. The inner wall surface of the measurement guide rail 601 is slidably connected with the driven roller 602. One side surface of the driven roller 602 is rotatably connected with the measurement base 603. One side surface of the measurement base 603 is fixedly connected with the measurement motor 604. One side surface of the measurement motor 604 is fixedly connected with the drive belt 605. One side surface of the drive belt 605 is fixedly connected with the drive roller 606. One side surface of the measurement base 603 is fixedly connected with the snap female part 607. One side surface of the snap female part 607 is attached to the snap male part 608. One side surface of the snap male part 608 is fixedly connected with the limit spring 609. One side surface of the snap male part 608 is fixedly connected with the release rod 610. One side surface of the limit spring 609 is fixedly connected with the limit plate 611. The upper surface of the limit plate 611 is fixedly connected with the infrared base 612. The upper surface of the infrared base 612 is fixedly connected with the infrared reactor 613. Through the setting of the infrared measurement mechanism 6, during use, after being powered on, the infrared reactor 613 and the measurement motor 604 are started. The measurement motor 604 drives the drive belt 605 to rotate, and the drive belt 605 drives the drive roller 606 to rotate, causing the measurement base 603 to move. The driven roller 602 rotates along the measurement guide rail 601 to achieve up and down movement. The infrared reactors 613 corresponding to the eight groups of measurement guide rails 601 emit and receive refracted waves from each other and transmit the data to the control panel 5 for calibration. When the infrared reactor 613 needs to be replaced, the release rod 610 is pulled, driving the snap male part 608 to compress the limit spring 609, releasing the limit of the snap female part 607 on the snap male part 608, and completing the disassembly of the installation between the infrared base 612 and the measurement base 603. During installation, when pressure is applied to the infrared base 612, the snap male part 608 slides along the snap female part 607, and the limit spring 609 releases elastic potential energy to push the snap male part 608 to achieve clamping. It can realize the movement of the measurement base 603 along the measurement guide rail 601 by means of the motor, belt, and roller, use multiple groups of infrared reactors 613 to emit and receive refracted waves for size measurement and calibration, and can also replace the infrared base 612 conveniently and quickly. Moreover, the comparison of the data of multiple groups of guide rails reduces the measurement error, improves the measurement accuracy, and the maintenance convenience of the equipment.

[0020] Furthermore, two groups of storage guide rails 4 are symmetrically arranged with respect to the central axis of the mounting shell 1, and the storage plate 3 is slidably connected to the mounting shell 1 through the storage guide rails 4. Through the arrangement of the storage guide rails 4 and the storage plate 3, when in use, the storage plate 3 can slide smoothly in the mounting shell 1, which is convenient for placing and removing standard parts or actual metal castings. At the same time, the symmetrically arranged structure enhances the stability and balance of the storage plate 3 when sliding, and improves the convenience and fluency of operation.

[0021] Furthermore, two groups of driving rollers 606 and driven rollers 602 are symmetrically arranged around the central axis of the mounting shell 1. The measuring motor 604 is fixedly connected to the driving roller 606 via a driving belt 605. By arranging the measuring motor 604, the driving roller 606 and the driven roller 602, when in use, the measuring base 603 can maintain balance and stability during movement. The measuring motor 604 drives the roller 606 to rotate via the driving belt 605, thereby effectively transmitting power and driving the measuring base 603 to move smoothly along the measuring guide rail 601, thereby ensuring the accuracy of transmitting and receiving refracted waves between the infrared reactors 613 and improving the accuracy and reliability of dimensional measurement.

[0022] Furthermore, eight groups of measuring guide rails 601 are symmetrically arranged with respect to the central axis of the mounting shell 1, and the measuring base 603 is slidably connected to the measuring guide rails 601 through the driving roller 606 and the driven roller 602. Through the arrangement of the measuring guide rails 601 and the measuring base 603, when in use, the eight groups of symmetrically arranged measuring guide rails 601 can make the measuring base 603 be uniformly stressed during the sliding process, thereby ensuring the smoothness of the movement. At the same time, the infrared reactors 613 corresponding to the multiple measuring guide rails 601 can cooperate with each other, obtain multiple groups of data by emitting and receiving refracted waves and compare them with each other, thereby effectively reducing measurement errors, improving the accuracy and reliability of metal casting size measurement, and enhancing the accuracy and credibility of the measurement results.

[0023] Furthermore, two groups of female snap-fit parts 607, male snap-fit parts 608, limit springs 609 and release rods 610 are symmetrically arranged on the central axis of each group of infrared bases 612. The infrared base 612 is fixedly connected to the measuring base 603 through the female snap-fit parts 607 and the male snap-fit parts 608. Through the arrangement of the female snap-fit parts 607, the male snap-fit parts 608, the limit springs 609 and the release rods 610, when in use, the two groups of symmetrically arranged snap-fit structures can make the connection between the infrared base 612 and the measuring base 603 more stable and reliable, thereby ensuring the stability of the infrared base 612 during the measurement process. When the infrared base 612 needs to be replaced, the release rod 610 can be pulled to conveniently release the connection. The limit spring 609 assists in the engagement and release operations, thereby making the installation and disassembly process of the infrared base 612 simple and efficient, facilitating the maintenance and overhaul of the equipment, and improving work efficiency.

[0024] Further, a sliding groove is provided on one side surface of the infrared base 612. The male snap member 608 is slidably connected to one side surface of the infrared base 612 through the sliding groove. With the setting of the infrared base 612, during use, the sliding groove provides a sliding track for the male snap member 608, enabling the male snap member 608 to slide smoothly on the infrared base 612, thereby facilitating the engagement and separation operations between the male snap member 608 and the female snap member 607. When it is necessary to install or remove the infrared base 612, the male snap member 608 can move flexibly along the sliding groove, reducing the operation difficulty, improving the convenience of installing and replacing the infrared base 612, and enhancing the stability and reliability of the connection structure.

[0025] Further, the casting detection mechanism 8 includes a detection base 801, a quality inspection housing 802, a fixed motor 803, a synchronous screw 804, fixed jaws 805, a limiting rod 806, a left - right moving guide rail 807, a left - right moving slider 808, a front - rear rodless cylinder 809, front - rear mounting plates 810, a detection magnet 811, a left - right rodless cylinder 812, and left - right mounting plates 813. One side surface of the mounting shell 1 is fixedly connected to the detection base 801. The upper surface of the detection base 801 is fixedly connected to the quality inspection housing 802. The outer surface of the quality inspection housing 802 is fixedly connected to the fixed motor 803. One side surface of the fixed motor 803 is fixedly connected to the synchronous screw 804. One side surface of the synchronous screw 804 is threadedly connected to the fixed jaws 805. One side surface of the fixed jaws 805 is slidably connected to the limiting rod 806. One side surface of the quality inspection housing 802 is fixedly connected to the left - right moving guide rail 807. One side surface of the left - right moving guide rail 807 is slidably connected to the left - right moving slider 808. One side surface of the left - right moving slider 808 is fixedly connected to the front - rear rodless cylinder 809. The upper surface of the front - rear rodless cylinder 809 is fixedly connected to the front - rear mounting plates 810. The lower surface of the front - rear rodless cylinder 809 is fixedly connected to the detection magnet 811. The lower surface of the front - rear rodless cylinder 809 is fixedly connected to the left - right rodless cylinder 812. The lower surface of the left - right rodless cylinder 812 is fixedly connected to the left - right mounting plates 813. Through the setting of the casting detection mechanism 8, during use, the fixed motor 803 starts to drive the synchronous screw 804 to rotate. The two sets of reverse threads on the outer side of the synchronous screw 804 drive the fixed jaws 805 to move. The fixed jaws 805 are restricted by the limiting rod 806 and move along the threads to achieve synchronous clamping and slightly lift the casting. The left - right rodless cylinder 812 pushes the front - rear mounting plates 810 and the front - rear rodless cylinder 809 to move, driving the left - right moving slider 808 to slide along the left - right moving guide rail 807. The front - rear rodless cylinder 809 drives the detection magnet 811 to detect the magnet to be measured, and the data is transmitted to the control panel 5. The cooperation of the fixed motor 803, the synchronous screw 804, and the fixed jaws 805 realizes synchronous clamping of the casting. The rodless cylinder drives the detection magnet 811 to detect the casting, which can accurately detect the defects and errors of the casting, improving the efficiency and accuracy of casting detection.

[0026] Further, two sets of threads with opposite spiral directions are arranged on the outer surface of the synchronous screw 804. The synchronous screw 804 is rotationally connected to the fixed jaws 805 through the threads. Through the setting of the synchronous screw 804, during use, the fixed motor 803 drives the synchronous screw 804 to rotate. The two sets of reverse threads can make the two fixed jaws 805 achieve synchronous movement towards or away from each other, thereby performing fast and stable synchronous clamping or loosening operations on the metal casting, improving the efficiency and accuracy of casting fixation, and ensuring the smooth progress of subsequent detection work.

[0027] Furthermore, two groups of fixed jaws 805 are arranged on the central axis of the quality inspection shell 802. The quality inspection shell 802 is slidably connected to the fixed jaws 805 through the limit rod 806. Through the setting of the fixed jaws 805 and the quality inspection shell 802, when in use, the two groups of fixed jaws 805 can synchronously clamp the metal casting from both sides, ensuring the uniform distribution of the clamping force and making the casting fixed more stably. The limit rod 806 guides and limits the sliding of the fixed jaws 805, ensuring that the fixed jaws 805 move in a straight line, avoiding the jaws from deflecting or shaking during movement, and improving the accuracy and reliability of casting fixation and detection.

[0028] Furthermore, the left and right rodless cylinders 812 are rotatably connected to the left and right movable sliders 808 through the front and rear mounting plates 810, and the front and rear rodless cylinders 809 are perpendicularly intersected with the left and right rodless cylinders 812. Through the arrangement of the left and right rodless cylinders 812 and the front and rear rodless cylinders 809, when in use, the left and right rodless cylinders 812 can drive the left and right movable sliders 808 to move in the left and right directions through the front and rear mounting plates 810, and the front and rear rodless cylinders 809 can drive the detection magnet 811 to move in the front and rear directions. The two are vertically coordinated with each other, so that the detection magnet 811 can be flexibly moved in a two-dimensional plane, thereby realizing a more comprehensive and detailed detection of the surface of the metal casting, covering all parts of the casting, improving the range and accuracy of the detection of casting defects or errors, and enhancing the effectiveness and accuracy of the detection work.

[0029] Working principle: For a fast-calibrating metal casting size measuring instrument, when in use, power is supplied. The placement board 3 is pulled, and the placement board 3 slides along the inner wall surface of the placement guide rail 4 to pull out the installation shell 1. The standard part is placed on the placement board 3, and the placement board 3 is pushed into the installation shell 1 along the placement guide rail 4. At this time, the light-shielding cloth fixedly connected to one side surface of the installation shell 1 blocks the external notch of the installation shell 1. In the infrared measurement mechanism 6, the infrared reactor 613 starts, and the measurement motor 604 starts. The measurement motor 604 drives the driving belt 605 to rotate. The rotation of the driving belt 605 drives the driving roller 606 fixedly connected to one side surface of the driving belt 605 to rotate, thereby driving the measurement base 603 to move, and further driving the driven roller 602 to rotate along the measurement guide rail 601, realizing the up and down movement along the measurement guide rail 601. The infrared reactors 613 corresponding to the eight groups of measurement guide rails 601 emit and receive refracted waves to each other, and conduct the data to the control panel 5 fixedly connected to one side surface of the installation shell 1. Size calibration is performed according to the actual parameters of the standard part. After the calibration is completed, the actual metal casting is subjected to the same operation to obtain corresponding data, and based on this, it is judged whether the processing size of the casting meets the standard range. When a certain amount of castings are detected, the infrared reactor 613 may affect the actual data due to the aging of the working circuit. At this time, the release rod 610 should be pulled. The release rod 610 drives the male snap member 608 to press the limit spring 609, releasing the limit effect of the female snap member 607 on the male snap member 608, and the engagement is released, realizing the disassembly of the installation of the infrared base 612 and the measurement base 603. A slight pressure is applied to the infrared base 612 to be replaced along the measurement base 603. The male snap member 608 slides along one side surface of the female snap member 607. When exceeding the necessary limit, the limit spring 609 releases the elastic potential energy generated when being pressed by the male snap member 608 and the limit plate 611, and pushes the male snap member 608 to slide along the chute provided on the inner wall of the infrared base 612, realizing the engagement and facilitating the simple installation. During the measurement, the data generated in multiple groups of guide rails are compared with each other to reduce errors. After that, the fixing motor 803 starts. The fixing motor 803 drives the synchronous screw 804 to rotate. The outer surface of the synchronous screw 804 has two threads with opposite spiral directions, driving the fixed jaws 805 to move. When the fixed jaws 805 move, they are restricted by the limit rod 806 slidably connected to one side surface of the fixed jaws 805 and move along the threads on the outer surface of the synchronous screw 804 to achieve synchronous clamping. During the clamping and fixing process, the semi-circular cross-section of the fixed jaws 805 will slightly lift the casting to be measured. The left and right rodless cylinders 812 push the front and rear mounting plates 810 and the front and rear rodless cylinders 809 to move, thereby driving the left and right moving sliders 808 to slide along one side surface of the left and right moving guide rails 807. The front and rear rodless cylinders 809 drive the detection magnetic block 811 to detect the magnetic block to be measured, and the data is conducted to the control panel 5 to analyze whether there are specific defects or errors. Among them, the models of the measurement motor 604 and the fixing motor 803 are YE2-132S-4.
