Description

Technical Field

[0001] The utility model relates to the technical field of micrometer verification, and specifically relates to a micrometer verification device. Background Art

[0002] Micrometers are precision measuring tools widely used in laboratories, production workshops, quality control and other fields, and are used to measure tiny dimensions, lengths, angles and other parameters. With the development of industrial automation and digitization, the demand for micrometers and the accuracy requirements are getting higher and higher, so micrometer verification has also received more and more attention. When performing micrometer verification, a micrometer is usually required for measurement work.

[0003] When using a micrometer for micrometer verification, it is necessary to hold the test object and place it between the detection parts of the micrometer. There will be a shielding phenomenon during the holding process. If the calibration is not carried out correctly, its accuracy may be affected, thus affecting the measurement result. Moreover, the height change of the test object will also cause errors, which may cause the measurement result to deviate from the actual value, and the reading deviation may lead to misleading results. Therefore, we propose a micrometer verification device to ensure the accuracy and reliability of the measurement result. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a micrometer verification device to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a micrometer verification device, including a frame, one side of the top of the inner ring wall of the frame is fixedly connected with an anvil, the other side of the top of the inner ring wall of the frame is fixedly connected with a micrometer screw, a square groove is opened in the inner cavity of the frame, a lifting structure is arranged at the square groove of the frame, and the bottom of the lifting structure is threadedly connected with the center of the frame.

[0006] Preferably, the lifting structure includes a round rod, both ends of the round rod are fixedly connected with the square groove of the frame, a sleeve block is sleeved on the outer wall of the round rod, a supporting plate is fixedly connected to the side wall of the sleeve block, magnets are symmetrically and fixedly connected to the upper surface of the supporting plate, and the magnets are symmetrically arranged vertically. A round groove block is fixedly connected to the lower surface of the supporting plate, a rotating block is sleeved in the inner cavity of the round groove block, the rotating block is rotatably connected with the inner cavity of the round groove block, a screw rod is fixedly connected to the lower surface of the rotating block, and the outer wall of the screw rod is threadedly connected with the center of the frame.

[0007] Preferably, two brackets are fixedly connected to the lower surface of the frame, and the brackets are symmetrically arranged horizontally. The other ends of the brackets are fixedly connected with a base.

[0008] Preferably, circular holes are symmetrically formed on the surface of the base, and the circular holes are symmetrically arranged horizontally.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows: When performing side micrometer verification, a lifting structure is provided to lift the test object between the anvil and the micrometer screw. During this process, observation can be better carried out. Instead of holding the test object by hand, it is stably fixed between the anvil and the micrometer screw through magnetic suction lifting. In this way, the state of the test object can be observed more clearly, avoiding the observation difficulties caused by hand-held occlusion. Then, measurement is carried out through the micrometer screw. Since the lifting structure can stably lift the test object, factors such as hand-held jitter or tilt that may cause errors are avoided, thereby improving the measurement accuracy. Correct calibration can be performed to ensure its precision and prevent errors from affecting the measurement results. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0015] Please refer to Figures 1-3 , the present utility model provides a micrometer verification device, including a frame 1. One side of the top of the inner ring wall of the frame 1 is fixedly connected with an anvil 3, and the other side of the top of the inner ring wall of the frame 1 is fixedly connected with a micrometer screw 4. A square groove is formed in the inner cavity of the frame 1, and a lifting structure 2 is arranged at the square groove of the frame 1. The bottom of the lifting structure 2 is threadedly connected with the center of the frame 1.

[0016] The lifting structure 2 includes a round rod 21. Both ends of the round rod 21 are fixedly connected to the square groove of the ruler frame 1. A sleeve block 22 is sleeved on the outer wall of the round rod 21. A support plate 23 is fixedly connected to the side wall of the sleeve block 22. Magnet 24s are symmetrically and fixedly connected to the upper surface of the support plate 23, and the magnet 24s are symmetrically arranged vertically. A round groove block 25 is fixedly connected to the lower surface of the support plate 23. A rotating block 26 is sleeved in the inner cavity of the round groove block 25. The rotating block 26 is rotatably connected to the inner cavity of the round groove block 25. A screw rod 27 is fixedly connected to the lower surface of the rotating block 26. The outer wall of the screw rod 27 is threadedly connected to the center of the ruler frame 1.

[0017] A support 5 is fixedly connected to the lower surface of the ruler frame 1. The number of supports 5 is two, and they are symmetrically arranged horizontally. The other end of the support 5 is fixedly connected to a base 6.

[0018] Round holes are symmetrically formed on the surface of the base 6, and the round holes are symmetrically arranged horizontally.

[0019] When performing side micrometer verification, the bottom of the ruler frame 1 is supported by the support 5. Round holes are formed on the surface of the base 6, and it can be fixed through components such as screws. The base 6 realizes stable fixation, enabling the ruler frame 1 to be more stably supported. Then, the test item is placed on the surface of the lifting structure 2. If the test object is a metal product, it can be adsorbed by the magnet 24 in the lifting structure 2 and stably fixed on the surface of the support plate 23. A sleeve block 22 is arranged on one side of the support plate 23. The sleeve block 22 is sleeved on the round rod 21 and slides. Both ends of the round rod 21 are fixed in the square groove opened on one side of the ruler frame 1. Then, by rotating the screw column 27, the screw column 27 is threadedly connected to the ruler frame 1. By rotating it, it moves, thereby driving the rotating block 26 to rotate in the inner cavity of the round groove block 25 and pushing the support plate 23 upward to move. During this process, it is possible to observe better without the situation of being blocked by hand. The test object is moved to the top of the ruler frame 1 and fits against the anvil 3 on one side. The ruler frame 1, the anvil 3, and the micrometer screw 4 form a complete micrometer. Then, rotate the part of the micrometer screw 4, slowly rotate it to make it move, and observe the differential cylinder on one side of the micrometer screw 4. When the edge of the differential cylinder shows the highest point, immediately stop rotating. At this time, the reading of the micrometer screw 4 is the measured value, and the overall micrometer verification work is completed.
