Description

Technical Field

[0001] This utility model relates to the field of optical measurement technology, specifically to an optical measurement device. Background Technology

[0002] In the field of optical measurement technology, whether it is the dimensional accuracy inspection of industrial parts, the surface morphology measurement of electronic components, or the assembly and calibration of precision instruments, it is necessary to place the optical measurement device stably on the measuring platform and use a fixed structure to limit and fix the device to ensure that the relative position of the device and the object being measured remains constant during the measurement process. This is the basic premise for ensuring the accuracy of the measurement data.

[0003] Currently, measuring equipment typically uses bolt clamping, clamping, and magnetic fixation. During actual measurement, the optical components and circuit modules inside the equipment generate periodic vibrations. These vibrations are transmitted to the fixed structure through the equipment housing. The vibrations cause the connection between the fixed structure and the measuring device to loosen, such as the bolts rotating slightly or the clamping jaws sliding relative to the device housing. This results in horizontal or vertical displacement of the entire device on the measuring platform, which in turn affects the accuracy of the measurement results. Utility Model Content

[0004] The purpose of this utility model is to provide an optical measuring device to solve the problems mentioned in the background art. To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model is an optical measuring device, comprising:

[0006] Measuring machine;

[0007] The fastening components include a vertical plate, a limiting plate, a support plate, a groove, and clamping claws. The vertical plate is welded to both sides of the outer surface of the measuring machine. The groove is opened on the upper part of the outer surface of the vertical plate. The limiting plate is slidably connected to the inside of the groove. The support plate is fixed to the upper part of both ends of the outer surface of the vertical plate. The clamping claws are slidably connected to the outer surface of the support plate, and their inner surfaces are clamped to the outside of the limiting plate.

[0008] Furthermore, a limit block is fixedly connected to the outer end of the support plate.

[0009] Furthermore, a slot is provided on the outside of one end of the clamping claw, and an insert is provided on the outside of the other end of the clamping claw, the insert being inserted into and connected to the inside of the slot.

[0010] Furthermore, the top of the upright plate is provided with an internal threaded ring, and a threaded rod is threadedly connected to the middle of the internal threaded ring.

[0011] Furthermore, a handle is fixedly connected to the top of the threaded rod, and the bottom of the threaded rod abuts against the top of the limiting plate.

[0012] Furthermore, it also includes a damage prevention component, which includes a rubber strip and a clamping block. The rubber strip is embedded in one side of the outer surface of the limiting plate, and the clamping block is fixed to both ends of the rubber strip and clamped to both ends of the limiting plate.

[0013] Furthermore, the limiting plate has magnetic grooves at both ends, and the clamping block has a magnetic block at one end, which is attached to the inside of the magnetic groove.

[0014] This utility model has the following beneficial effects:

[0015] This invention utilizes a fastening mechanism to first clamp the device to be measured on both sides via a slidable clamping plate. Then, by rotating the handle, the threaded rod is driven to rotate within the internal threaded ring, causing the bottom of the threaded rod to abut against the top of the clamping plate, creating a longitudinal clamping force. Finally, the clamping claws slide outside the support plate, further clamping the device from the outside of the clamping plate. Simultaneously, the insert block is inserted into the slot to lock the lateral position of the clamping plate a second time, creating multiple fixing effects. This significantly improves the connection stability between the fixing structure and the measuring device, and enhances the accuracy of the measurement results. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] Please see Figure 1-4 As shown, this utility model is an optical measuring device, comprising:

[0029] Measuring machine 11;

[0030] The optional model of the measuring machine 11 is the Keyence TM-3000 series. It projects a laser beam onto the surface of an object to form a scattered light spot. The camera captures the position of the light spot from a specific angle and calculates the change in the height of the object's surface by combining trigonometric relationships.

[0031] The fastening components include a vertical plate 21, a limiting plate 22, a support plate 24, a groove 25, and a clamping claw 26. The vertical plate 21 is welded to both sides of the outer surface of the measuring machine 11. The groove 25 is opened on the upper part of the outer surface of the vertical plate 21. The limiting plate 22 is slidably connected to the inside of the groove 25. The support plate 24 is fixed to the upper part of both ends of the outer surface of the vertical plate 21. The clamping claw 26 is slidably connected to the outer surface of the support plate 24, and its inner surface is clamped to the outside of the limiting plate 22.

[0032] When the inner wall of the clamping claw 26 is tightly fitted with the outer wall of the limiting plate 22, the sliding clamping claw 26 stops. At this time, the clamping claw 26 performs a secondary lateral clamping from the outside of the limiting plate 22, further reducing the distance between the two limiting plates 22 and enhancing the lateral clamping force on the measuring device.

[0033] A limit block 23 is fixedly connected to the outer end of the support plate 24.

[0034] One end of the clamping claw 26 has a slot 28 on its outside, and the other end of the clamping claw 26 has a plug 27 on its outside, which is inserted into and connected to the inside of the slot 28.

[0035] The engagement of the insert 27 and the slot 28 prevents the clamping claw 26 from sliding during vibration, further locking the position of the limiting plate 22.

[0036] The top of the upright plate 21 is provided with an internal threaded ring 33, and the middle part of the internal threaded ring 33 is threadedly connected to a threaded rod 31;

[0037] A handle 32 is fixedly connected to the top of the threaded rod 31, and the bottom of the threaded rod 31 abuts against the top of the limiting plate 22;

[0038] The threaded rod 31 exerts downward longitudinal pressure on the limiting plate 22. This pressure presses the limiting plate 22 tightly against the bottom of the groove 25, restricting the vertical movement of the limiting plate 22.

[0039] Working principle:

[0040] After placing the optical device to be measured on the preset measurement area on the surface of the measuring machine 11, push the limiting plates 22 on both sides to slide along the length direction of the groove 25. Adjust the distance between the limiting plates 22 on both sides according to the actual width of the measuring device until the inner side wall of the limiting plate 22 is tightly fitted with the side walls of the measuring device. Turn the handle 32. Since the threaded rod 31 and the internal threaded ring 33 are threadedly engaged, under the rotation of the handle 32, the bottom of the threaded rod 31 is completely pressed against the top of the limiting plate 22. Then push the two clamping claws 26 on the outside of the support plate 24 so that the clamping claws 26 slide along the length direction of the support plate 24 towards the limiting plate 22. When the inner side wall of the clamping claw 26 is tightly fitted with the outer side wall of the limiting plate 22, stop sliding the clamping claw 26. At this time, the clamping claw 26 clamps the limiting plate 22 laterally from the outside, while the insert block 27 is inserted into the slot 28 at the same time.

[0041] Through the above three steps, the measuring device is finally in a triple-fixed state: the side limit plates 22 are laterally clamped, the top threaded rod 31 is longitudinally pressed, and the outer clamping claw 26 is laterally locked. This provides a stable reference for optical measurement, thereby improving the accuracy of the measurement results.

[0042] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0043] The anti-damage component includes a rubber strip 41 and a clamping block 42. The rubber strip 41 is embedded in one side of the outer surface of the limiting plate 22, and the clamping block 42 is fixed to both ends of the rubber strip 41 and clamped to both ends of the limiting plate 22.

[0044] The rubber strip 41 has good softness and elasticity, which can prevent physical damage such as scratches and indentations to the surface of the measuring device caused by excessive pressure or uneven contact surface during the clamping process of the limiting plate 22. Especially for fragile measuring devices with optical lenses, precision sensors or coatings on the surface, it can effectively protect their sensitive parts, prevent the device function from being damaged due to clamping operation, and reduce equipment maintenance costs and damage risks.

[0045] The limiting plate 22 has magnetic grooves 44 at both ends, and a magnetic block 43 is provided at one end of the clamping block 42. The magnetic block 43 is attached to the inside of the magnetic groove 44.

[0046] The magnetic block 43 and the magnetic groove 44 adsorb and cooperate to fix the rubber strip 41 tightly to the side of the limiting plate 22, preventing the rubber strip 41 from warping or falling off during device clamping and equipment vibration.

[0047] Working principle:

[0048] First, install the rubber strip 41 on one side of the limiting plate 22, clamp the clamping block 42 at both ends of the limiting plate 22, and simultaneously attract the magnetic block 43 at the inner end of the clamping block 42 to the inside of the magnetic groove 44 opened at both ends of the limiting plate 22, so that the rubber strip 41 is fixedly installed on one side of the limiting plate 22.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.

This utility model is limited only by the claims and their full scope and equivalents.
