Embodiment Construction

[0017] Such as figure 1 As shown, 12 in the figure is a platform, and 2 is a corrugated pipe to be tested. On the horizontal platform 12, two parallel left vertical boards 1 and right vertical boards 7 are vertically arranged. Between the plates 7, there is a bellows 2 to be tested, one end of which is fixed on the left vertical plate 1, and the other end of the bellows 2 to be tested is installed on the right vertical plate through the slider 3, the linear bearing group 4 and the slide rail 6. 7, the linear bearing group 4 can freely slide up and down with low frictional resistance along the vertical direction on the slide rail 6, and a steering bearing pulley block 8 is also fixedly arranged on the top of the right vertical plate 7 through the support angle steel 9, and the steering bearing pulley block Soft thin wire rope 10 is installed on 8, and one end of this wire rope 10 is connected with the top of linear bearing group 4, and the other end of wire rope 10 is then conn...

Abstract

The invention discloses a device for testing the transverse stiffness of a corrugated pipe, and the device comprises a rack. The technical main points are that the horizontal rack is vertically provided with two parallel vertical plates, and a to-be-tested corrugated pipe with one end being fixed on the first vertical plate is disposed between the two vertical plates. The other end of the corrugated pipe is connected with a linear bearing group which is installed on the second vertical plate and freely slides in the vertical direction through a sliding block. The top of the second vertical plate is also fixedly provided with a steering bearing pulley block, and a steel wire rope is disposed on the steering bearing pulley block. One end of the steel wire rope is connected with the top of the linear bearing group, and the other end of the steel wire rope is connected with a balance weight. The top of the sliding block is also provided with a press rod which is of a point contact type andis provided with a sensor. According to the invention, because the linear bearing group with the high precision and low friction is used for reducing the friction resistance in the vertical direction, and the sliding block is connected with a sliding end of the corrugated pipe. Meanwhile, the sliding block is connected with the balance weight, achieving a purpose of enabling the corrugated pipe to be in a self-balance state during testing. Moreover, the friction resistance interference is low, and there is no interference load.

Description

technical field [0001] The invention belongs to the technical field of bellows stiffness detection, in particular to a bellows transverse stiffness testing device when a metal bellows is subjected to a transverse load. Background technique [0002] As we all know, due to its own characteristics, bellows are widely used in industry. For bellows, its stiffness parameter is one of the important indicators. There are mainly four kinds of bellows stiffness parameters, including: axial stiffness, transverse stiffness, bending stiffness, and torsional stiffness. Among them, the axial stiffness is widely used, and the test method is perfect. However, there are few introductions to the transverse stiffness test, and there are no domestic test plans and methods reported. Therefore, in order to solve the problem of the transverse stiffness test of the bellows, it is necessary to develop a test device for the transverse stiffness of the bellows. Contents of the invention [0003] T...
