Problems solved by technology

Therefore, the traditional method of measuring fasteners with ordinary tools is far from meeting the requirements, and more and more workpieces need to be measured on universal tool microscopes or coordinate measuring machines
However, in the traditional measurement method, fasteners are clamped by tools such as calipers, and the clamping tool has a large clamping area for the measured fastener, and even sometimes due to the Due to factors such as specifications, there is a problem that the fastener cannot be clamped
This makes it impossible to accurately collect points when using a universal tool microscope and a three-coordinate measuring machine to measure fasteners, which leads to the inability to complete the measurement at one time, resulting in a decrease in the efficiency of fastener measurement and an increase in labor intensity.

Embodiment Construction

[0016] Examples of clamping tooling for fastener measurement, such as Figure 1-4 As shown, the clamping tool for fastener measurement includes a base 11 and a pressing part, and the pressing part includes a support frame 12 and a pressing screw 13 .

[0017] The base 11 is in the shape of a plate, and a positioning groove 14 is provided at one edge of the base 11. The positioning groove 14 runs through the thickness direction of the plate formed by the base 11. In this embodiment, the positioning groove 14 is a V-shaped groove. The locating groove is more helpful for centering the fastener under test. In addition, in this embodiment, the bottom of the positioning groove 14 is also provided with an impurity accommodating groove 15. During the use process, the impurities dropped from the fastener to be tested can accumulate in it, so as to prevent it from being cushioned by the fastener. The accuracy of the measurement results is affected by the measurement under the fastener....

Abstract

The invention relates to the field of mechanical fastener measurement, in particular to a clamping tool for fastener measurement. The clamping tool for fastener measurement comprises a base and a press component matched with the base. A locating groove which is used for locating a measured fastener is formed in the base, the press component comprises a supporting frame and a forcing screw, and the forcing screw is assembled on the supporting frame in a threaded mode; in addition, a separation-preventing structure which is used for keeping separation-preventing matching between the supporting frame and the base in the axial direction of the forcing screw when the measured fastener is tightly pressed is arranged between the supporting frame and the base; the base and the supporting frame are respectively in a plate shape, and the locating groove extends in the thickness direction of a plate formed by the base. According to the clamping tool for fastener measurement, fastener measurement efficiency is improved, and labor intensity of fastener measurement is reduced.

Description

technical field [0001] The invention relates to the field of mechanical fastener measurement, in particular to a clamping tool used for fastener measurement. Background technique [0002] Standard fasteners are the most common components in the mechanical field, and fasteners are used in almost all mechanical devices. Today, standard fasteners are widely used in the aviation and aerospace fields. [0003] At present, with the rapid development of aerospace technology, stricter requirements are also placed on the size and geometric tolerances of standard fasteners. Therefore, the traditional method of measuring fasteners with ordinary tools is far from meeting the requirements, and more and more workpieces need to be measured on a universal tool microscope or a CMM. However, in the traditional measurement method, the fasteners are clamped by tools such as calipers, and the clamping tool has a large clamping area for the measured fasteners, and even in some cases, the faste...
