Horizontal push-pull force tester

Abstract

The invention relates to the technical field of mechanical property tests, and discloses a horizontal push-pull force tester. The horizontal push-pull force tester comprises a fine tuning module, a tensiometer, a coarse tuning module, a base, precise guide rails and a transitional plate, wherein the fine tuning module comprises a tension fine tuning handle wheel, a lead screw and a lead screw seat; the forwarding or retracting of the lead screw is controlled by the forward and reverse rotation of the tension fine tuning handle wheel; the other end of the lead screw is contacted with the precise guide rails fixedly provided with the tensiometer and the transitional plate; and the accurate position of the transitional plate on the precise guide rails can be controlled. The coarse tuning module comprises a winding wheel, a winding handle, a ratchet wheel and a bearing seat; and the winding handle controls the ratchet wheel to rotate only toward one direction by the bearing seat and generate stepping. The horizontal push-pull force tester can carry out detection of mechanical tension or thrust on a single product, and has the advantages that the testing value is accurate, the error is less and the occupied space is less. In addition, by applying the fine tuning function of the horizontal push-pull force tester, the tension can be increased at constant speed, and the product is prevented from being damaged after being impacted by sudden force in the testing process.

Description

technical field [0001] The invention relates to the technical field of mechanical performance testing, in particular to a technology mainly used for testing the performance of products under tensile loads, in particular to a technology for manually testing the push-pull force of products using a tension meter. Background technique [0002] At present, in the optical communication industry, in the international general optical performance test standard, some optical indicators are tested under the state of mechanical load. In order to avoid the instability of the measured value, the error of the test device must be reduced. [0003] In the optical fiber communication industry, the vertical tensile test method is often used to test the optical performance of optical products under tensile load. Vertical tensile test method (such as Figure 1a , Figure 1b (shown) is used by many jumper and pigtail manufacturers. During the test, one end of the product to be tested is fixed on...

Problems solved by technology

This method has the following disadvantages: (1) a large amount of weights are needed to realize the fine-tuning of the scale, which undoubtedly increases the cost

(2) After obtaining the total mass M of the weight, it needs to be converted into a gravity value in units of N, which increases the complexity

(3) The increase or decrease of weights also requires human co...
