Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of measuring tools, in particular to a placing bracket for a lever micrometer. Background Art
[0002] A lever micrometer is a general-purpose precision length measuring tool that uses the lever principle and an indicating gauge to read the distance divided between two measuring surfaces on an arc-shaped ruler frame. It is composed of an outside micrometer and an indicating gauge. The lever micrometer can be used for relative measurement and can also be used for absolute measurement like a micrometer. Its graduation values are 0.001 mm and 0.002 mm. The lever micrometer not only has a high reading accuracy, but also has a relatively large stiffness of the bow-shaped frame, and the measuring force is generated by a small spring, which is more stable than the measuring force generated by the ratchet device of an ordinary micrometer. Therefore, its actual measurement accuracy is also relatively high. When measuring with a lever micrometer, it needs to be clamped and fixed with a placing rack. Before the lever micrometer is used for relative measurement, the zero position should be adjusted with gauge blocks according to the size of the workpiece to be measured. When measuring, press the retraction button to gently contact the workpiece with the measuring rod surface, and do not force it to clamp to avoid wear of the measuring surface and affect the accuracy.
[0003] In the prior art, due to the limited range of the adjustable angle of the placing rack, the measuring felt of the lever micrometer can only contact the part to be measured at a fixed position. After a period of use, the fixed position on the measuring felt is prone to wear, resulting in a short service life of the measuring felt and the need for frequent replacement. Summary of the Utility Model
[0004] In order to make up for the above deficiencies, the utility model provides a placing bracket for a lever micrometer, aiming to improve the problems that the adjustable angle range of the prior art is limited and the bracket cannot move, which is not convenient for observing the lever micrometer.
[0005] To achieve the above object, the utility model provides the following technical solution: A placing bracket for a lever micrometer, including a base, a chute is opened at the top of the base, limiting teeth are symmetrically arranged on both sides inside the chute, a workbench is arranged at the top of the chute, a pressing plate table is arranged at the top of the workbench, a groove is opened at the top of the pressing plate table, a pressing plate is arranged at the top of the groove, a spring is connected to the bottom of the pressing plate, the spring is arranged at the bottom of the groove, a connecting rod is fixedly connected to the bottom of the pressing plate, the connecting rod penetrates through the pressing plate table and the workbench, and a limiting plate is arranged at the bottom of the connecting rod.

[0023] Referring to Figures 1-5 , an embodiment provided by the present invention: A placing bracket for a lever micrometer, including a base 1. A chute 9 is opened at the top of the base 1. Limiting teeth 8 are symmetrically arranged on both sides in the chute 9. There is a certain blank space below the limiting teeth 8. A workbench 2 is arranged at the top of the chute 9. The workbench 2 can move and change its position on the top of the base 1 through the chute 9. A pressing plate table 10 is arranged at the top of the workbench 2. A groove is opened at the top of the pressing plate table 10. A pressing plate 13 is arranged at the top of the groove. The pressing plate 13 can move up and down in the groove. A spring 14 is connected to the bottom of the pressing plate 13. The spring 14 is arranged at the bottom of the groove. The pressing plate 13 is supported by the spring 14 to exceed the top surface height of the pressing plate table 10. A connecting rod 11 is fixedly connected to the bottom of the pressing plate 13. The connecting rod 11 passes through the pressing plate table 10 and the workbench 2. A limiting plate 12 is arranged at the bottom of the connecting rod 11. The limiting plate 12 is stuck between the limiting teeth 8 to fix the workbench 2. Press down the pressing plate 10, drive the limiting plate 12 at the bottom to move downward through the connecting rod 11, and get rid of the fixing effect of the limiting teeth 8. Move the workbench 2 forward or backward. After determining the position, the elastic force of the spring 14 at the bottom of the pressing plate 13 will rebound the pressing plate 13, drive the limiting plate 12 to snap into the limiting teeth 8, and thus fix the workbench 2.
[0024] Referring to Figures 1-5, a second bump 16 is provided on the top of the workbench 2. A rotatable support plate 3 is rotatably connected inside the second bump 16. The support plate 3 can rotate around the second bump 16 as the center. A connecting sleeve 21 is provided on the right bottom surface of the support plate 3. One end of a support rod 17 is movably connected to the connecting sleeve 21. A group of support blocks 19 are provided on the top of the workbench 2.
