Assembling device for installing torsion rod spring

Abstract

The invention provides an assembling device for installing a torsion rod spring. The assembling device comprises a main rod serving as a main structure, a threaded sleeve connected and positioned withthe main rod, a positioning block used for positioning the fixed position of a vehicle body spline, a spline head and a bolt head used for positioning the spline, a fixing pin used for positioning the tool state and a knocking hammer serving as a stress application tool. The spline head is fixedly connected with the threaded sleeve, the main rod penetrates through the middle of the threaded sleeve, the end, provided with the positioning pin hole, of the main rod is aligned with the positioning pin hole in the spline head, the positioning pin penetrates into the positioning pin hole to fix thespline head and the main rod, the knocking hammer sleeves the middle of the main rod, and the positioning block penetrates through the tail of the main rod and is fixedly connected. The bolt head isconnected to the tail of the main rod. The stress application requirements of different states can be met, and the flexible design of the whole device is improved; under the condition that the main body structure of the device is not changed, the core structure can be quickly replaced, the device utilization rate is improved, and the device modification cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of torsion bar spring assembly, and in particular relates to an assembly device for torsion bar spring assembly. Background technique [0002] The main body of the torsion bar spring is a straight rod, and the torsional deformation of the rod is used to act as a spring. Torsion bar springs are mainly used for: 1) Suspension springs of cars and small vehicles; 2) Since torsion bar springs do not vibrate like coil springs when subjected to high-frequency vibration loads, torsion bar springs can be used in high-speed internal combustion engines As a valve spring; 3) Insert a torsion bar spring in the drive shaft to ease the change of torque; 4) Use a large torsion bar spring as a voltage regulator on railway vehicles and automobiles that use air spring buffers; 5) Armored vehicles, etc. Special equipment shock absorber and suspension device. [0003] According to different structures, torsion bar springs main...

Problems solved by technology

[0006] The present invention proposes an assembly device for torsion bar spring installation to solve the problem of rod spring installation process. The interference in the installation process is difficult to ensure smooth installation, and its action position is not easy to use pressure equipment and devices. Knocking will cause local cracks, fractures and other technical problems that lead to local stress concentration and torsion bar spring failure
