Embodiment Construction

[0016] Below in conjunction with accompanying drawing this patent is described in further detail:

[0017] like Figure 1 to Figure 4 As shown in Fig. 1 , a mechanism for adjusting the center of mass of the moment arm for a small torque standard device is specially suitable for a symmetrical moment arm structure with a small volume. It mainly includes: Adjusting handle 1, counterweight nut 4, screw rod 3, first bearing 2, structural square tube frame 5, leveling arm 6, second bearing 7, positioning block 8, positioning screw 9, friction spring piece 10 , major axis 11, fixed plate 12 is installed.

[0018] The structural square pipe frame 5 is welded by horizontal square pipes, vertical square pipes and intermediate square pipes, wherein the horizontal square pipes are connected to the vertical square pipes through the middle square pipes; The first bearings 2 are installed on both sides, and a screw rod 3 is passed through the middle of the first bearing 2 on both sides. Th...

Abstract

The invention relates to a mass center adjusting mechanism for a force arm of a mini torque standard device. The adjusting mechanism comprises adjusting handles, counterweight nuts, lead screws, a structural square tube rack, a positioning block and a positioning screw; the structural square tube rack is formed by welding a horizontal square tube, a vertical square tube and a middle square tube, and the horizontal square tube is connected with the vertical square tube via the middle square tube; an installation fixed plate is fixed and welded to the middle position of the vertical square tube, and a leveling force arm is fixedly connected via the installation fixed plate; first bearings are mounted at the two sides of the horizontal square tube respectively, one lead screw penetrates the middle of the horizontal square tube by being supported by the first bearings at the two sides, the adjusting handles are fixed at the two sides of the lead screw, and the lead screw is connected with the counterweight nut in a cooperated manner; and the other leading screw and the other counterweight nut are mounted in the middle of the vertical square tube, a threaded hole is formed in the tube wall in the middle position of the vertical square tube, the positioning screw compresses the positioning block at the inner side of the vertical square tube through the threaded hole, and the upper end of the positioning block supports the lead screw. The adjusting mechanism is suitable for the symmetrical force arm structure of small size, and can be used to level the force arm of the mini dead weight type torque standard device.

Description

technical field [0001] The invention relates to a tiny torque standard device used for measurement detection, torque detection calibration, and torque test, in particular to a force arm mass center adjustment mechanism for the tiny torque standard device. Background technique [0002] The moment arm of the deadweight torque standard device generally adopts a symmetrical structure, and its center of mass is designed at the center of rotation. However, usually due to design requirements, material uniformity, machining accuracy and other reasons, the center of mass of the arm that is actually manufactured often cannot coincide with the ideal position. Therefore, it is necessary to adjust the center of mass of the arm to restore it to the center of rotation, so as to reduce the influence of the center of mass of the arm on the measured torque value and improve the accuracy of the device. The existing adjustment method of the center of mass of the force arm is to adjust by adopt...
