Tester displacement measuring and limit device

Abstract

The invention discloses a tester displacement measuring and limit device. The device comprises a pedestal, a fixing bracket, a guyed photoelectric encoder and a limit device, wherein the pedestal and the fixing bracket are positioned below a workbench; the fixing bracket is fixedly arranged on one side of the pedestal through a screw; the guyed photoelectric encoder is fixedly arranged on the fixing bracket through an encoder base; a hook is arranged on the lower surface of the workbench; the top end of an extending part of the guyed photoelectric encoder is connected with the hook; the limit device comprises a limit rod, a limit plate and a limit switch; the upper end of the limit rod is fixedly arranged on the lower surface of the workbench; the limit plate is fixedly arranged on the limit rod through a nut; and the limit switch is arranged on the side, opposite to the limit plate, of the fixing bracket. By the device, displacement can be measured in a testing process, the displacement measuring precision can be better ensured, the accuracy of test is ensured, a limit control function can also be finished, and the cost and the space are saved.

Description

technical field [0001] The invention relates to a displacement measuring and limiting device, in particular to a displacement measuring and limiting device for a testing machine position. Background technique [0002] At present, with the development of society and the rapid advancement of technology, the displacement measurement of the testing machine has already risen from the initial scale measurement to the measurement of the photoelectric encoder, and various displacement measuring devices and limit measuring devices are connected to the testing machine. The most common displacement measurement device is composed of base, vertical plate, mobile frame, hook, spring, rotating shaft, stop wheel, wire clamp, hook, stopper, workbench and other components. Due to many parts, the link is complicated. It affects the accuracy of measurement, which directly leads to the accuracy of test results, and also brings great troubles to the calculation of test results; the commonly used ...
