Description

Technical Field

[0001] The present invention relates to the technical field of optical measurement, and particularly relates to an adjustable optical measuring instrument for image and dimension measurement. Background Art

[0002] An optical measuring instrument is a precision measuring device based on optical imaging and digital image processing technologies, mainly used for non-contact measurement of dimensions, shapes, contours and surface features. It is widely used in industrial inspection, quality control, scientific research experiments and other fields, especially suitable for workpieces that are small, easily deformed or have high precision requirements.

[0003] The working principle of an optical image measuring instrument is to collect images of the object to be measured through a measuring lens, extract edge contour features using computer image processing technology, and calculate the geometric dimensions of the workpiece in combination with the coordinate data of a precision grating scale. The measuring lens plays an important role in measuring the workpiece. When the device is not in use, the air flow in the space will carry suspended particles in the environment, and these particles will directly impact and adhere to the lens surface along the air flow trajectory. Dust will cause blurred imaging, deviation in edge recognition, and even be misjudged as the workpiece contour, directly affecting the measurement accuracy. Therefore, this solution proposes an adjustable optical measuring instrument for image and dimension measurement to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] The present invention provides as Figures 1-6An adjustable optical measuring instrument for image and size measurement shown in the figure includes:

[0038] A measuring instrument body 1;

[0039] A measuring lens 2, and the measuring lens 2 is arranged on the top of the measuring instrument body 1;

[0040] A protective cover 3, and the protective cover 3 is sleeved at the bottom of the measuring lens 2;

[0041] A connecting block 4, and the connecting block 4 is fixedly connected to one side of the protective cover 3;

[0042] A movable rod 5, and the movable rod 5 is fixedly connected to one side of the connecting block 4;

[0043] A limiting component 6, and the limiting component 6 is arranged on one side of the measuring instrument body 1. The limiting component 6 is used to limit the moving distance of the protective cover 3;

[0044] A fixing component 7, and the fixing component 7 is arranged on one side of the measuring instrument body 1. The fixing component 7 is used to fix the position of the protective cover 3.

[0045] It should be noted that the set measuring instrument body 1 and measuring lens 2 are precision optical image measuring instruments of model WEIMI322PS; the set protective cover 3 is adapted to the measuring lens 2, so that the protective cover 3 can be sleeved at the bottom of the measuring lens 2, and the bottom of the measuring lens 2 is protected by the protective cover 3 to avoid the accumulation of dust at the bottom of the measuring lens 2; when the optical measuring instrument is not in use, the protective cover 3 is moved to the bottom of the measuring lens 2, and the bottom of the measuring lens 2 is protected by the protective cover 3 to avoid the accumulation of dust at the bottom of the measuring lens 2, thereby avoiding the situation that the measurement result deviates from the actual result due to the blockage of dust on the measuring lens 2 during use.

[0046] Specifically, the limiting component 6 includes:

[0047] A fixed rod 601, and the fixed rod 601 is fixedly connected to one side of the measuring instrument body 1. A chute 603 is opened at the top of the movable rod 5, and the fixed rod 601 is inserted into the inside of the chute 603;

[0048] A blocking block 602, and the blocking block 602 is arranged on one side of the movable rod 5. The blocking block 602 is fixedly connected to one side of the fixed rod 601, and the blocking block 602 is used to limit the moving direction of the movable rod 5.

[0049] It should be noted that the fixed rod 601 is adapted to the provided chute 603, enabling the movable rod 5 to slide on one side of the measuring instrument body 1 through the chute 603, thereby adjusting the height of the protective cover 3. At the same time, the movable rod 5 can rotate around the fixed rod 601 to adjust the position of the protective cover 3, turning the protective cover 3 away from the bottom of the measuring lens 2 to avoid the situation where the protective cover 3 blocks the measuring lens 2.

[0050] Specifically, the fixing assembly 7 includes:

[0051] A clamping block 704, which is inserted and connected to one side of the blocking block 602. A clamping hole 705 is provided on one side of the movable rod 5, and the clamping block 704 is inserted and connected inside the clamping hole 705;

[0052] A turntable 706, which is fixedly connected to one side of the clamping block 704. A cavity 707 is provided in the middle of the blocking block 602, and the turntable 706 is inserted and connected inside the cavity 707;

[0053] A moving member 8, which is arranged on one side of the turntable 706 and is used to move the position of the turntable 706.

[0054] It should be noted that the number of the provided clamping holes 705 is two, and the two clamping holes 705 are respectively located at the top and bottom of the chute 603, and the distances between the two clamping holes 705 and the chute 603 are the same; when it is necessary to fix the position of the movable rod 5, the position of the movable rod 5 is restricted by the fixed rod 601 at the fixed position and the clamping block 704 that restricts movement, so that the movable rod 5 cannot move.

[0055] Furthermore, when it is necessary to move the protective cover 3 out from the bottom of the measuring lens 2, first move the clamping block 704 out of one of the clamping holes 705, then move the protective cover 3 to the side away from the measuring lens 2. After the protective cover 3 is separated from the measuring lens 2, then rotate the movable rod 5 around the fixed rod 601. After rotating the fixed rod 601 by 180 degrees, move the clamping block 704 until it aligns with the other clamping hole 705, and then move the clamping block 704 into the other clamping hole 705 to fix the position of the movable rod 5 through the clamping block 704.

[0056] Specifically, a locking block 703 is fixedly connected to the top of the turntable 706, and a locking hole 708 is provided on the inner wall of the bottom end of the cavity 707. The locking block 703 and the locking hole 708 are used to restrict the movement of the clamping block 704.

[0057] It should be noted that the provided locking hole 708 is for the locking block 703 to penetrate. During use, when it is necessary to move the position of the locking block 704 out of the locking hole 705 and position it, the turntable 706 is moved to align with the locking hole 708. Then, the turntable 706 is rotated, and the locking block 703 on the turntable 706 is rotated into the interior of the locking hole 708. The movement of the locking block 703 is blocked by the inner wall on one side of the locking hole 708, thereby restricting the position of the locking block 703. By restricting the movement of the locking block 703, the movement of the turntable 706 and the locking block 704 is restricted, preventing the locking block 704 from moving randomly during use.

[0058] Specifically, a fixed block 701 is fixedly connected to the inner wall on one side of the cavity 707. A fixing groove 702 is provided on one side of the locking block 703, and the fixed block 701 is inserted into the interior of the fixing groove 702.

[0059] It should be noted that the provided fixing groove 702 is adapted to the set fixed block 701, enabling the fixed block 701 to penetrate into the interior of the fixing groove 702. By the fixed block 701, the rotation of the locking block 703 around the locking block 704 is restricted.

[0060] Specifically, the moving member 8 includes a pushing block 807 provided on one side of the turntable 706. A spring 803 is provided on one side of the pushing block 807. Both the spring 803 and the pushing block 807 are inserted into the interior of the cavity 707. A limiting portion 9 is provided inside the cavity 707. A connecting rod 802 is fixedly connected to one side of the turntable 706. The connecting rod 802 is inserted into the inner wall on the other side of the cavity 707. A pulling block 801 is provided on one side of the connecting rod 802. A connecting hole 804 is provided in the middle of the pushing block 807, and the connecting rod 802 is inserted into the interior of the connecting hole 804. A limiting groove 806 is provided on the inner wall in the middle of the connecting hole 804. A limiting ring 805 is sleeved on one side of the connecting rod 802, and the limiting ring 805 is inserted into the interior of the limiting groove 806.

[0061] It should be noted that the provided pushing block 807 is adapted to the provided cavity 707, enabling the pushing block 807 to slide inside the cavity 707. The provided spring 803 is located on the side of the pushing block 807 away from the turntable 706. The pushing block 807 is pushed towards the side of the turntable 706 by the spring 803. The horizontal longitudinal cross-sections of the provided limiting groove 806 and the limiting ring 805 are both circular rings, enabling the limiting ring 805 to rotate inside the limiting groove 806. Due to the restriction of the limiting groove 806, the limiting ring 805 cannot move out of the limiting groove 806. Thus, when the connecting rod 802 moves, it drives the pushing block 807 to move, and the connecting rod 802 can rotate in the middle of the pushing block 807.

[0062] Further, when it is necessary to fix the position of the clamping block 704:

[0063] First step, by pulling the pulling block 801 to drive the connecting rod 802, the pushing block 807, the turntable 706 and the clamping block 704 to move, move the clamping block 704 out of the clamping hole 705. At the same time, the spring 803 deforms after being squeezed by the pushing block 807;

[0064] Second step, when the locking block 703 on the outer wall of the turntable 706 moves to align with the locking hole 708, by pulling the pulling block 801 to drive the connecting rod 802, the turntable 706 and the locking block 703 to rotate, rotate the locking block 703 into the locking hole 708, and limit the movement of the locking block 703 through the locking hole 708.

[0065] Specifically, the limiting part 9 includes a positioning block 901 fixedly connected to the inner wall of the top of the cavity 707. A positioning groove 902 is opened at the top of the pushing block 807, and the positioning block 901 is inserted into the positioning groove 902.

[0066] It should be noted that the opened positioning groove 902 is adapted to the set positioning block 901, so that the positioning block 901 can be inserted into the top of the pushing block 807 through the positioning groove 902, and through the limitation of the positioning block 901, the situation that the pushing block 807 rotates inside the cavity 707 is avoided.

[0067] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
