Description

Technical Field

[0001] This utility model relates to the field of image measuring instrument technology, and in particular to an adjustable gantry frame for a gantry-type image measuring instrument. Background Technology

[0002] The image measuring instrument, also known as a precision image mapping instrument, represents a qualitative leap from the digital display projector. It is an upgraded version of the projector, overcoming the shortcomings of traditional projectors. It is a new type of high-precision, high-tech measuring instrument integrating optics, mechanics, electronics, and computer imaging technology. It uses an optical microscope to perform high-magnification optical magnification imaging of the object under test. After the magnified image of the object is sent to the computer through a CCD camera system, it can efficiently detect the contours, surface shapes, dimensions, angles, and positions of various complex workpieces. In particular, it is used for the microscopic inspection and quality control of precision parts. When inspecting parts, a gantry-type image measuring instrument is required, which uses an adjustable gantry to adjust the detector for inspection.

[0003] Existing technologies, such as patent CN214065973U, disclose an adjustable gantry frame for a gantry-type image measuring instrument. This patent employs a worktable, a gantry frame, and a measuring head. The gantry frame is positioned on top of the worktable, and the measuring head is mounted on the gantry frame. Fixed plates and motors are symmetrically arranged on both sides of the top of the worktable. The motor is located behind the fixed plate, and a movable plate is positioned between the motor and the fixed plate. A threaded rod is connected to the output end of the motor, and the front end of the threaded rod passes through the movable plate and is connected to a bearing in the fixed plate. The threaded rod is threadedly connected to the movable plate. A sliding block is located in the middle of the bottom of the movable plate, and a limiting block is located at the bottom of the sliding block. Symmetrically connected sliding grooves and limiting grooves are provided on both sides of the top of the worktable. This utility model device solves the problem that existing equipment is difficult to move the detector, making it difficult to accurately inspect parts.

[0004] In daily operation, the equipment has problems such as difficulty in accurately detecting items on the surface of the plate, and difficulty in moving the detector according to the size, shape and measurement area requirements of different objects, resulting in the equipment being unable to adapt to different items. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where it is difficult to move the detector to detect objects, and to propose an adjustable gantry frame for a gantry-type image measuring instrument.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable gantry frame for a gantry-type image measuring instrument, comprising a main body, a placement plate, a connecting frame, and a detector. The placement plate is located at the upper end of the main body, the connecting frame is located at the upper end of the main body, the detector is located on the side of the connecting frame, and a positioning device is provided on the side of the connecting frame. The positioning device includes a slide rail and a connecting arm. The connecting arm is fixedly connected to the side of the connecting frame, the slide rail is fixedly connected to the side of the main body, and the connecting arm is slidably connected inside the slide rail. A positioning groove is formed on the surface of the slide rail, a connecting block is fixedly connected to the side of the connecting arm, a positioning plate is rotatably connected inside the connecting block, the positioning plate is engaged with the inside of the positioning groove, and a limit block is fixedly connected to the side of the positioning plate.

[0007] Furthermore, two mounting blocks are fixedly connected to the side of the connecting arm, and two sliding rods are fixedly connected inside the two mounting blocks. By setting two sliding rods, the movement of the clamping rod can be limited, reducing the situation where the clamping rod is difficult to move smoothly during use, making it difficult for the clamping rod to be positioned and fixed by the positioning plate.

[0008] Furthermore, the surfaces of the two slide rods are slidably connected with locking rods, which engage with the inside of the limiting block. The limiting block is provided to facilitate limiting the locking rods.

[0009] Furthermore, a spring is sleeved and connected to the surface of the slide rod, and the two ends of the spring are fixedly connected to the surface of the clamp rod and the surface of the mounting block, respectively. The spring facilitates the application of a restoring force to the clamp rod.

[0010] Furthermore, a cleaning device is provided at the upper end of the main body. The cleaning device includes a chute and a moving block. The chute is opened at the upper end of the main body, and the moving block is slidably connected inside the chute. A cleaning plate is fixedly connected to the side of the moving block, and a cleaning cotton is fixedly connected to the lower end of the cleaning plate. A spring rod is fixedly connected to the side of the moving block. By providing the cleaning cotton, the surface of the placement plate can be cleaned, reducing the difficulty of cleaning foreign objects on the surface of the placement plate during equipment use.

[0011] Furthermore, a retaining ball is fixedly connected to the end of the elastic rod away from the moving block. The surface of the retaining ball is provided with a retaining sleeve, and the elastic rod is provided to facilitate the application of a moving elastic force to the retaining ball.

[0012] Furthermore, the sleeve is fixedly connected to the upper end of the main body, and a pull rod is fixedly connected to the side of the elastic rod to facilitate the movement of the elastic rod.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, when using the equipment, the user places the part to be tested on the surface of the placement plate, and then starts the equipment detector to test the part. When using the equipment, the user moves the lever downward. When the lever moves, it causes the spring to displace and deform, generating elastic force. Then the lever moves away from the inside of the limiting block, and the positioning plate is unrestrained. The positioning plate rotates and displaces from the inside of the positioning groove, and the connecting frame is unrestrained. Moving the connecting frame moves and adjusts the detector. By setting up a positioning device, the connecting frame is effectively moved and positioned, which plays the role of adjusting the connecting frame. This reduces the difficulty for the detector to accurately detect items on the surface of the placement plate when using the equipment. It also reduces the difficulty for the equipment to move the detector according to different measurement object sizes, shapes, and measurement area requirements, resulting in the equipment being unable to adapt to different items. This positioning device can adjust and fix the position of the connecting frame, greatly improving the adaptability to different measurement scenarios and meeting diverse measurement needs.

[0015] 2. In this utility model, by setting up a cleaning device, when the user moves the pull rod downwards, the pull rod moves and drives the elastic rod to move. When the elastic rod moves, it drives the locking ball to move out of the inside of the locking sleeve, and then the moving block is unrestrained. Then, the moving block is pulled to drive the cleaning plate to move the cleaning cotton. When the cleaning cotton moves, it cleans the surface of the placement plate. By setting up a cleaning device, the surface of the placement plate is effectively cleaned, which plays a role in cleaning the surface of the placement plate. This reduces the possibility that foreign objects on the surface of the placement plate will affect the detection of the equipment. This cleaning device can clean the surface of the placement plate and greatly improve the accuracy of the equipment in detecting items. Attached Figure Description

[0022] Please see Figures 1-5 This utility model provides a technical solution: an adjustable gantry frame for a gantry-type image measuring instrument, including a main body 1, a placement plate 2, a connecting frame 3 and a detector 4. The placement plate 2 is located at the upper end of the main body 1, the connecting frame 3 is located at the upper end of the main body 1, and the detector 4 is located on the side of the connecting frame 3.

[0023] The specific setup and function of the positioning device 5 and the cleaning device 6 will be explained in detail below.

[0024] In this embodiment: a positioning device 5 is provided on the side of the connecting frame 3. The positioning device 5 includes a slide rail 51 and a connecting arm 52. The connecting arm 52 is fixedly connected to the side of the connecting frame 3. The slide rail 51 is fixedly connected to the side of the main body 1. The connecting arm 52 is slidably connected inside the slide rail 51. A positioning groove 53 is opened on the surface of the slide rail 51. A connecting block 55 is fixedly connected to the side of the connecting arm 52. A positioning plate 54 is rotatably connected inside the connecting block 55. The positioning plate 54 is engaged with the inside of the positioning groove 53. A limit block 56 is fixedly connected to the side of the positioning plate 54.

[0025] Specifically, two mounting blocks 510 are fixedly connected to the side of the connecting arm 52, and two slide rods 58 are fixedly connected inside the two mounting blocks 510.

[0026] In this embodiment: by setting two sliding rods 58, the locking rod 57 can be limited to move, which reduces the difficulty of the locking rod 57 moving smoothly during use, thus preventing the locking rod 57 from being fixed by the positioning plate 54.

[0027] Specifically, the surfaces of the two slide rods 58 are slidably connected to a locking rod 57, which engages with the inside of a limiting block 56. The limiting block 56 is provided to facilitate limiting the locking rod 57.

[0028] Specifically, a spring 59 is sleeved and connected to the surface of the slide rod 58. The two ends of the spring 59 are fixedly connected to the surface of the clamp rod 57 and the surface of the mounting block 510, respectively. The spring 59 is provided to facilitate the application of a restoring force to the clamp rod 57.

[0029] In this embodiment: a cleaning device 6 is provided at the upper end of the main body 1. The cleaning device 6 includes a chute 61 and a moving block 62. The chute 61 is opened at the upper end of the main body 1. The moving block 62 is slidably connected inside the chute 61. A cleaning plate 63 is fixedly connected to the side of the moving block 62. A cleaning cotton 64 is fixedly connected to the lower end of the cleaning plate 63. A spring rod 67 is fixedly connected to the side of the moving block 62.

[0030] In this embodiment: by setting cleaning cotton 64, the surface of the placement plate 2 can be cleaned, reducing the difficulty of cleaning foreign objects on the surface of the placement plate 2 during use of the equipment.

[0031] Specifically, a retaining ball 66 is fixedly connected to the end of the elastic rod 67 away from the moving block 62. A retaining sleeve 65 is provided on the surface of the retaining ball 66. The elastic rod 67 is provided to facilitate the application of a moving elastic force to the retaining ball 66.

[0032] Specifically, the sleeve 65 is fixedly connected to the upper end of the main body 1, and the side of the elastic rod 67 is fixedly connected to the pull rod 68. The pull rod 68 is provided to facilitate the movement of the elastic rod 67.

[0033] Working Principle: When using the equipment, the user places the part to be tested on the surface of the placement plate 2, and then activates the detector 4 to test the part. During use, the user moves the lever 57 downwards. When the lever 57 moves, it causes the spring 59 to deform and generate elastic force. The lever 57 then moves away from the limit block 56, and the positioning plate 54 is released from its restraint. Rotating the positioning plate 54, it moves away from the positioning groove 53, and the connecting frame 3 is released from its restraint. Moving the connecting frame 3 adjusts the detector 4. By setting the positioning device 5, the connecting frame 3 is effectively moved and positioned, thus adjusting it. This reduces the difficulty for the detector 4 to accurately test items on the surface of the placement plate 2, and the difficulty for the equipment to move according to different measurement object sizes, shapes, and measurement area requirements, resulting in the equipment being unsuitable for different items. This positioning device 5 can adjust and fix the position of the connecting frame 3, greatly improving its adaptability to different measurement scenarios and meeting diverse measurement needs.

[0034] When the device is in use, the user moves the pull rod 68 downwards, which in turn moves the elastic rod 67. When the elastic rod 67 moves, it causes the locking ball 66 to move and disengage from the inside of the locking sleeve 65. Then, the moving block 62 is unrestrained and is pulled to move the cleaning plate 63 to move the cleaning cotton 64. When the cleaning cotton 64 moves, it cleans the surface of the placement plate 2. By setting up the cleaning device 6, the surface of the placement plate 2 is effectively cleaned, which reduces the possibility that foreign objects on the surface of the placement plate 2 may affect the device's detection. This cleaning device 6 can clean the surface of the placement plate 2, greatly improving the accuracy of the device in detecting items.
