Fixing device on spiral spring torque detection equipment

Abstract

The invention provides a fixing device on spiral spring torque detection equipment. A spiral spring of which the two ends of the spring body have no connecting part, the pitch is large, the number of coils is high, the length is high and the internal and external diameter is large can be fixed on the spiral spring torque detection equipment to perform torque detection, and the frictional force in the detection process is low and detection is relatively accurate and reliable. Left and right fixing members are installed at the two sides of a spindle in a sleeving way through left and right axial connecting through holes, and the openings of the left axial annular fixing groove of the left fixing member and the right axial annular fixing groove of the right fixing member are opposite. The left and right ends of the left fixing member are respectively connected with the rotating part and the fixing part on the spiral spring torque detection equipment. A supporting member is rotatably installed on the spindle in the sleeving way through an axial assembling hole and positioned between the left and right fixing members, and the two ends are abutted against the left and right ends of the left and right fixing members. The left and right ends of the spindle are respectively connected with the rotating part and the fixing part on the spiral spring torque detection equipment.

Description

technical field [0001] The invention relates to torsion spring torque detection equipment, in particular to a fixing device on the helical spring torque detection equipment. Background technique [0002] Those skilled in the art know that a common helical spring includes a spring body and connecting parts protruding from both ends of the spring body, and has a small pitch, a small number of turns, a short length, and small inner and outer diameters. The torque of this common helical spring can usually be detected by using a traditional fixing device composed of a mandrel, which is fixed on a traditional helical spring torque testing device. When testing, put the spring body of this coil spring on the mandrel, connect the connecting parts at both ends to the fixed end and the rotating end of the coil spring torque testing equipment, and connect one end of the mandrel to the coil spring torque testing device. The fixed end on the device is connected, and the rotation of the f...

Problems solved by technology

Therefore, the frictional force is large, so that the detection of the torque of the coil spring 40 is not accurate enough

[0005] The second is that this coil spring 40 cannot be directly connected through the fixed end and the rotating end on the coil spring torque detection equipment, it is difficult to fix, and it is difficult to fix
