Abstract

The invention relates to a chain length measuring instrument, comprising a chain tension mechanism and a chain length measuring mechanism. The chain tension mechanism comprises a servo motor, wherein the servo motor drives a lead screw B to rotate to drive a movable gripper seat to move on a liner guide rail B and a liner guide rail C straight so as to tension the chain. The chain length measuring mechanism comprises a sensing head and an encoder, wherein the motor drives a lead screw A to rotate to drive a sensing head to move on a liner guide rail A straight so as to measure the chain length. The invention has the advantages that the tension force can be preset by a control panel, and the servo motor tensions the chain, therefore, the control is accurate and reliable. The motor drives the sensing head to measure the chain length, the encoder counts the number and transfers the number to the control panel so as to automatically display the chain length. Therefore, the invention has the advantages of high accuracy, default control and automatic data display, convenient reading, high efficiency, and the like.

Description

technical field

[0001] The chain length measuring instrument of the invention relates to a measuring instrument for chain length. Background technique

[0002] The chain is a key part in the sprocket chain transmission, and the chain length is a key parameter. If the error of the chain length exceeds the standard, it will affect the transmission accuracy, efficiency and the service life of the sprocket chain. The existing chain length measuring instrument includes a chain tensioning mechanism and a length measuring mechanism. First, the chain is pre-tensioned to tension the chain, and then the length of the chain containing X chain links specified in the standard is measured. The chain tension is The tightening mechanism adopts a hydraulic mechanism. Since it is a hydraulic mechanism, pumps, valves, boxes, cylinders, pipes, meters, joints, etc. are indispensable in the system. The mechanism is complicated and bulky. The tension force applied is converted from the pressure di...
