Description
Technical field
The present invention is a kind of pressure fatigue test stand test piece fixing device, be to carry out the different shape of pressure fatigue test (resisting periodical change pressure effect fatigue failure test), the testpieces of various types for needs, provide warranty test safety, a kind of device that normally carries out are installed with fixing.
Technical background
Industries such as machinery, chemical industry are being used various device, and this wherein has large number quipments to be operated under the periodically variable pressure, and these equipment are all bearing the effect of rule or irregular alterante stress.Under the effect of periodically variable alterante stress, because the reason of the manufactured materials of equipment, or because the reason of production technology aspect can make fatigue of materials lose efficacy, intensity reduces, and influences the usability of product, and causes safety problem.Statistics shows, in the fracture accident of various machineries, nearly more than 80% since fatigue failure cause.Therefore,, check the ability of its antifatigue stress, in engineering is used, occupy an important position for the equipment equipment that bears alterante stress.The fatigue breakdown of commercial unit be long-term a, progressive formation slowly, and harm that it causes and consequence but is unexpected, and be instantaneous with unpredictable.In the suitability for industrialized production, in the short period of time, grasp the ability of the anti-alterante stress effect of product facility, under the alternating pressure effect, assessment is made in the security of equipment to product facility, seems extremely important.This just need be to the anti-alternating pressure fatigue effect of product facility and the ability that did not lose efficacy test.In test, testpieces is subjected to the effect of cyclical variation alternating pressure, must produce vibration, and generation displacement because vibrate, for normally carrying out of warranty test, for the personal safety in the warranty test,, must install with fixing the product or the parts of needs test for the safety of warranty test equipment.Because the pressure fatigue test platform, the testpieces of being faced is diversified, and size, shape and specification vary, for the various types testpieces, need a kind of easily, reliably, stationary installation safety, practicality, with the carrying out of warranty test.For this reason, we have invented pressure fatigue test stand test piece fixing device.
Summary of the invention
Technical matters: the purpose of this invention is to provide a kind of pressure fatigue test stand test piece fixing device, the space adjustable size can adapt to different shape, the different test piece of size specification.
Technical scheme: pressure fatigue test stand test piece fixing device of the present invention adopts following design proposal:
This device is formed backboard by backboard column and backboard crossbeam, and base longeron and base crossbeam are formed base, and clamping plate crossbeam and clamping plate column are formed clamping plate; The top of backboard is connected with the top of clamping plate by pull bar, and the bottom of backboard is connected an end of base, and clamping plate place the upper surface of base; The bottom of limited block is connected with base, and the movable push rod on the limited block is connected with the bottom of clamping plate.Clamping plate are made up of symmetrical two parts, and promptly the outside is the clamping plate column, and the inboard is the three clamping plate crossbeams in upper, middle and lower, and symmetrical two parts clamping plate crossbeam is connected by contiguous block, and is fixed by coupling bolt.Limited block is a square, and its lower plane is fixed on the base by the bolt pair, and its vertical plane is provided with a screw, and movable push rod is spun in this screw, and the front end of movable push rod is connected with the bottom of clamping plate, plays regulating action.
The installation that this device is used for various testpieces on the pressure fatigue test platform is with fixing, for the testpieces of various types provides the installation of simple and fast, the safety of warranty test simultaneously.
Beneficial effect: the invention has the advantages that,
1) backboard columns assemblies and base and cleat assembly form a test piece installing space, and the space adjustable size can adapt to different shape, the different test piece of size specification;
2) adopt backboard columns assemblies, base assembly and cleat assembly, in conjunction with pull bar, push rod and limited block, test piece is formed constraint, with the displacement of restriction workpiece, fitting operation is very easy.
3) enough spaces are left in the testpieces left and right sides, and adapter connects simple and easy to do.
Description of drawings
Fig. 1 is the perspective view of structure of the invention process,
Fig. 2 is the connection diagram of limited block 5 parts.
Have among the above figure: backboard 1, backboard column 11, backboard crossbeam 12, base 2, base longeron 21, base crossbeam 22, clamping plate 3, clamping plate crossbeam 31, clamping plate column 32, contiguous block 33, coupling bolt 34, pull bar 4, limited block 5, movable push rod 51.
Embodiment
Pressure fatigue test stand test piece fixing device of the present invention is formed backboard 1 by backboard column 11 and backboard crossbeam 12, and base longeron 21 is formed base 2 with base crossbeam 22, and clamping plate crossbeam 31 is formed clamping plate 3 with clamping plate column 32; The top of backboard 1 is connected with the top of clamping plate 3 by pull bar 4, and the bottom of backboard 1 is connected an end of base 2, and the bottom of clamping plate 3 is connected the middle part of base 2; The bottom of limited block 5 is connected with base 2, on the limited block 5
Its operating process is as follows: test specimen is positioned between backboard 1 and the clamping plate 3.The test specimen less for length dimension only uses right clamping plate; For the bigger test specimen of length dimension, utilize contiguous block 33 and coupling bolt 34 that left and right sides clamping plate are formed a whole.Select suitable position to install and fix limited block 5 according to the size of specimen thickness size, screw the movable push rod 51 on the limited block 5, and screw pull bar 4, test specimen is limited between backboard 1 and the clamping plate (3).
