Embodiment 1

[0018] Example 1, such as Figure 1-3 As shown, a chain tensile parameter testing device includes a workbench 1, on which a fixing seat 2 is fixedly welded, and the fixing seat 2 is fixedly connected to one end of the tested chain 11, and the other end of the tested chain 11 is connected to an adapter 3. The adapter 3 is connected to the base 43 , the tension gauge 4 is fixedly connected to the base 43 , and the base 43 is connected to the actuating device 5 . The actuating device 5 gives a force to make the tested chain 11 stretched and lengthened, the tension meter 4 displays the change of the tension, and the dial gauge 42 detects the movement of the adapter position to calculate the stretch coefficient of the tested chain 11. The actuating device 5 is connected with a control device 6, which can stably control the hydraulic transmission system to ensure the stability of the hydraulic output, and can automatically run the set program to avoid errors caused by manual operati...

Abstract

The invention discloses a chain tensile parameter testing device. The chain tensile parameter testing device comprises a worktable, and further comprises a fixing seat, an adapter, a tension meter, a dial indicator and an actuating device, wherein the actuating device is used for stretching a tested chain, and the adapter is used for guaranteeing that the height of the tested chain and an action force of the actuating device are on the same horizontal plane. The chain tensile parameter testing device disclosed by the invention is simple in structure, low in cost, convenient to operate and capable of fast testing chain tensile parameters for a plurality of times.

Description

technical field [0001] The invention relates to mechanical testing equipment, especially a testing device for testing the tensile parameters of chains. Background technique [0002] Sprocket and chain transmission are common structures in the machinery industry. The stretch coefficient of the chain determines the quality of the chain. A chain that is easy to stretch is not easy to use. It should be that the pitch of the sprocket is immutable. When the chain is stretched, the pitch If there is a change, the sprocket and the chain will not fit well, which will cause many mechanical problems, so we must understand the stretch coefficient of the chain when using the sprocket chain, which is the key to quality control. [0003] For example, the chain pull button experiment machine with publication number 202403913U discloses a frame, a knob-turning stepper motor and a stretching stepper motor, and the knob-turning stepping motor and the stretching stepper motor are fixed on the f...
