Abstract
Description
Technical Field
[0001] The utility model relates to an inspection device for a tool, in particular to a measuring force detection device for an outside micrometer. Background Art
[0002] An outside micrometer is a precision length measuring instrument. The measuring force of an outside micrometer refers to the measuring force applied to the measured object when using the outside micrometer for measurement. If the measuring force of the outside micrometer is too large, elastic deformation will occur on the measured object or the measuring surface of the micrometer. For example, when measuring a softer material, excessive measuring force will cause the surface of the material to be indented, resulting in a larger measurement result. On the contrary, if the measuring force is too small, the measuring surface and the measured object will not contact sufficiently, and the measurement result will also be inaccurate. To ensure the measurement accuracy of the outside micrometer, it is necessary to regularly detect the measuring force of the differential measuring head of the outside micrometer to make it comply with relevant standards and specifications. At present, in the industry, a general measuring tool dynamometer is mainly used to measure the measuring force of the outside micrometer, but it can only measure outside micrometers within a small range, and outside micrometers with a diameter exceeding 100 mm cannot be measured. Moreover, when using a general measuring tool dynamometer, the clamping is unstable and the measurement repeatability is poor, resulting in an inability to accurately determine whether it is qualified. Summary of the Invention
[0003] The purpose of the utility model is to provide a measuring force detection device for an outside micrometer aiming at the defects existing in the above-mentioned prior art, which can quickly complete the clamping of the outside micrometer, directly read the data, and is convenient and fast to use.
[0004] The technical solution adopted by the utility model to achieve the above purpose is: a measuring force detection device for an outside micrometer, including a dynamometer, a dynamometer mounting plate, a slider, a guide rail, and a measuring block. The dynamometer is installed on the front surface of the dynamometer mounting plate, and the back surface of the dynamometer mounting plate is further connected to the inner surface of the slider. The slider is also sleeved on the guide rail and can move relative to the guide rail. When the slider moves along the guide rail, the overall structure composed of the dynamometer mounting plate and the dynamometer can also move relative to the guide rail. The measuring head of the dynamometer is connected to the right end of the dynamometer, and the measuring block is connected to the left end of the guide rail and extends to a position opposite to the measuring head of the dynamometer outside the left end of the dynamometer.
[0005] A further technical solution of the utility model is: it further includes a locking screw. A through threaded hole is provided on the outer side wall of the slider, and the locking screw is installed in the threaded hole. The relative position of the slider and the slide rail can be adjusted through the locking screw.
[0006] A further technical solution of the utility model is: two并列 threaded holes are provided on the outer side wall of the slider, and two locking screws are respectively installed in the two threaded holes.
[0007] A further technical solution of the utility model is: an inwardly concave measuring plane is provided on the side of the measuring block away from the slide rail, and the surface of the measuring plane is smooth and flat.
[0008] The utility model of the outside micrometer force measuring device has the following advantages: by installing the integral structure composed of the force gauge and the force gauge mounting plate on one side of the slider, and the measuring block connected to one end of the slide rail, the slider can move relative to the slide rail, and the outside micrometer can be quickly clamped on the outside of the force gauge probe and the measuring block.

[0015] like Figures 1 to 3 As shown, this utility model relates to a force measuring device for an outside micrometer, used to detect the force of the micrometer probe 11 on an outside micrometer 9. This utility model includes a force gauge 2, a force gauge mounting plate 4, a slider 5, a guide rail 1, a measuring block 7, and a locking screw 6.
[0016] like Figures 1 to 3As shown, the force gauge 2 is mounted on the front of the force gauge mounting plate 4, and the back of the force gauge mounting plate 4 is connected to the inner surface of the slider 5. The slider 5 is a cuboid slider with a groove in the middle. The slider 5 is fitted onto the guide rail 1 and can move relative to the guide rail 1. When the slider 5 moves with the guide rail 1, the overall structure formed by the force gauge mounting plate 4 and the force gauge 2 can also move relative to the guide rail 1. The outer wall of the slider 5 has a threaded hole that passes through the groove. The locking screw 6 is installed in the threaded hole, and the relative position of the slider 5 and the guide rail can be adjusted by the locking screw 6. Loosening the locking screw 6 allows the slider 5 to move relative to the guide rail 1, and tightening the locking screw 6 fixes the slider 5, i.e., it is fixed on the guide rail 1. In this embodiment, the outer wall of the slider 5 has two parallel threaded holes, and two locking screws 6 are installed in the two threaded holes respectively. Setting two locking screws 6 can more securely lock the slider 5 onto the guide rail 1.
[0017] like Figure 1 , Figure 2 As shown, the probe 3 of the force gauge 2 is connected to the right end of the force gauge 2. The force gauge 2 is an existing structure that can be purchased directly, and its structure will not be described in detail here. When the probe 3 of the force gauge 2 is pressed, the pressure can be read directly from the force gauge 2. The measuring block 7 is connected to the left end of the guide rail 1, and the measuring block 7 extends to the outer side of the left end of the force gauge 2, opposite to the probe 3 of the force gauge 2. The measuring block 7 has an inwardly recessed measuring plane 8 on the side away from the guide rail, and the surface of the measuring plane 8 is smooth and flat.
[0018] Usage instructions (e.g.) Figure 4 (As shown): 1. According to the measurement range of the outside micrometer 9 being measured, first loosen the locking screw 6, adjust the position of the slider 5 so that the distance from the outer end face of the probe 3 of the force gauge 2 to the measuring plane 8 of the measuring block 7 is within the measurement range of the outside micrometer 9, and then tighten the locking screw 6; 2. Make the fixed probe 10 of the outside micrometer 9 contact the measuring plane 8 of the measuring block 7, and the differential probe 11 contact the probe 3 of the force gauge 2. Rotate the micrometer measuring device of the outside micrometer 9 until the ratchet clicks, and read the force value from the force gauge 2. This value is the force measured by the outside micrometer 9.
