Technical Field
[0001] This utility model relates to the field of optical image measuring instrument technology, specifically to an optical image measuring instrument. Background Technology
[0002] An optical image measuring instrument is a measuring instrument that integrates optical, mechanical, electronic, and computer image processing technologies.
[0003] Chinese patent disclosure for an optical image measuring instrument, publication number CN207816188U, includes a support frame, a worktable mounted on the support frame, a fixed base and a glass stage mounted on the worktable, a measuring machine housing mounted on the fixed base, an optical component mounted at one end of the measuring machine housing, a linear groove provided inside the glass stage, a locking bolt fixed within the linear groove, a helical tension spring connected to the locking bolt, a sliding rubber block mounted at one end of the helical tension spring, telescopic cylinders fixed at both ends of the measuring machine housing, telescopic cylinders connected to telescopic iron rods, and an L-shaped dust cover mounted at one end of the telescopic iron rods, the length of the L-shaped dust cover being equal to that of the glass stage. This invention, by having the helical tension spring pull the sliding rubber block, can lock and fix the object being measured, improving the stability of the object and effectively improving the measurement accuracy of the optical image measuring instrument.
[0004] However, it still has the following drawbacks: the device uses the elastic force of a spring to slide a rubber block to detect the workpiece, but the clamping force varies for workpieces of different sizes; for larger workpieces, the clamping force is greater, making clamping more difficult. Therefore, we propose an optical image measuring instrument to solve this problem. Summary of the Invention
[0005] The purpose of this invention is to provide an optical image measuring instrument to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an optical image measuring instrument, comprising an operating table, wherein an installation device and an imaging component are provided on the operating table, and the installation device includes an adjustment unit;
[0007] The adjustment unit includes a servo motor. The right end face of the servo motor is fixedly connected to the left end face of the operating table. A sliding groove is provided on the top surface of the operating table. The outer surface of the output shaft of the servo motor rotates through the front of the operating table and extends into the sliding groove via a first bearing.
[0008] The operating table is equipped with a clamping part;
[0009] The clamping part includes a clamping plate and an operating rod. The clamping plate is slidably sleeved on the outer surface of the operating rod. A connecting rod is hinged to the bottom surface of the operating rod. A locking block is hinged to the bottom end of the connecting rod. The outer surface of the locking block is slidably connected to the inner wall of the clamping plate.
[0010] A further improvement is that the adjustment unit also includes a slider and a placement stage. The slider is threaded onto the outer surface of the servo motor output shaft, and the top surface of the slider is fixedly connected to the bottom surface of the placement stage. By setting up the servo motor, slider, and placement stage, the placement stage and the workpiece to be tested can be controlled to move left and right by starting the servo motor.
[0011] A further improvement is that the clamping part also includes a lead screw, a splicing rod, a limiting slider, a first bevel gear, a second bevel gear, a worm gear, a worm wheel, a rotating shaft, and a spring. A limiting groove is formed on the outer surface of the placement table. The limiting slider is threaded onto the outer surface of the lead screw. The outer surface of the limiting slider is slidably connected to the inner wall of the placement table. The outer surface of the lead screw is rotatably connected to the inner wall of the placement table through a first bearing seat. By setting the limiting slider, the lead screw, and the clamping plate, the rotation of the clamping plate is controlled by the lead screw, so that the clamping plate can stably clamp and position the workpiece to be measured.
[0012] A further improvement is that the outer surface of the rotating shaft is rotatably connected to the inner wall of the placement platform through the second bearing seat, the second bevel gear is fixedly sleeved on the outer surface of the rotating shaft, the first bevel gear is fixedly sleeved on the outer surface of the lead screw, and the outer surfaces of the first bevel gear and the second bevel gear are connected in a transmission manner. By setting the rotating shaft, the first bevel gear and the second bevel gear, it is convenient for the four lead screws to be linked together, so that the four lead screws can rotate at the same time, which facilitates the clamping plate to clamp and position the workpiece to be measured.
[0013] A further improvement is that the worm gear is fixedly sleeved on the outer surface of the rotating shaft, and the outer surface of the rear end of the worm rotates through the front of the placement platform and extends into the interior of the placement platform via the second bearing. The outer surface of the worm and the outer surface of the worm gear are connected in a transmission manner. By setting the worm and the worm gear, rotating the worm drives the rotating shaft to rotate, thereby adjusting the position of the clamping plate. At the same time, the self-locking property of the worm gear and the worm improves the stability of the clamping plate.
[0014] A further improvement is that the bottom surface of the splicing rod is fixedly connected to the outer surface of the limiting slider, and the bottom surface of the clamping plate is provided with a mating groove. The clamping plate is slidably sleeved on the outer surface of the splicing rod. By setting the splicing rod, it is convenient to quickly adjust the position of the clamping plate according to the size of the workpiece to be measured.
[0015] A further improvement is that a slot is provided on the outer surface of the splicing rod, and the outer surface of the locking block slides through the inner wall of the clamping plate and extends into the slot. The bottom end of the spring is fixedly connected to the inner wall of the operating rod, and the top end of the spring is fixedly connected to the inner wall of the clamping plate. By setting the operating rod, locking block, connecting rod and locking block, the elastic force of the spring is used to lock the splicing rod, which facilitates the quick assembly and docking of the clamping plate and the splicing rod.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] This optical image measuring instrument, through the setting of clamping plates, lead screws, splicing rods, limiting sliders, first bevel gears, second bevel gears, worm gears, worm wheels, and rotating shafts, allows for quick changes in the position of the clamping plates by fitting them onto the outer surface of the splicing rods, based on the size of the workpiece being measured. The worm gears are then rotated to drive the rotating shaft, and the first and second bevel gears drive the position of the limiting sliders and clamping plates, allowing for fine-tuning of the clamping plates and ensuring proper clamping and positioning of the workpiece, thus improving its stability.
[0018] By setting up a locking block, connecting rod, operating rod, and spring, the spring force is used to lock the splicing rod in place. By pulling the operating rod upward, the locking block is released from the splicing rod, making it easy to quickly adjust the position of the clamping plate.
[0019] By setting up a servo motor, slider, and placement stage, the servo motor is activated to facilitate the left and right movement of the placement plate and the workpiece to be tested. Attached Figure Description
