Abstract
The invention discloses an endurance test shock absorption tool which comprises an installation flat plate (1) and suspension column feet (10). Two side faces of the installation flat plate (1) are provided with through holes (4) respectively in the X direction and the Y direction. The through holes (4) vertically intersect to be of a crossed structure. Two balance screw rods (3) are arranged in the through holes (4) respectively. Locking nuts (5) are arranged at the two ends of each balance screw rod (3) respectively, the suspension column feet (10) are arranged at the four corners of the installation flat plate (1), and each suspension column foot (10) is composed of a pagoda-shaped spring (6), a sheath (7), a spring bottom seat (8) and a spring upper seat (9). The sheaths (7) are arranged outside the pagoda-shaped springs (6), the spring bottom seats (8) are arranged at the lower ends of the pagoda-shaped springs (6), and the spring upper seats (9) are arranged at the upper ends of the pagoda-shaped springs (6). The spring upper seats (9) are connected with the installation flat plate (1) which is provided with installation fixing screw holes (2). The endurance test shock absorption tool enables the center of gravity of an irregular structure to shift, and the irregular structure is balanced by adjusting the balance screw rod in the X direction and the balance screw rod in the Y direction, certain impact force and reaction force of the endurance test shock absorption tool body on a work table board can be eliminated, and the endurance test shock absorption tool is simple in structure, durable, and low in manufacturing cost.
Description
Technical field
The present invention relates to product testing durable test technical field, particularly relate to a kind of long duration test damping frock.
Background technology
Wherein motion structure part of some small-sized machine electronic products, in design trial-manufacturing process, need through motion long duration test, whether meet designing requirement in order to the material of verifying its structure and employing, meet the designed life of applying working condition, in test, need to have an installation flat board that it is fixedly vibrated or carry out reciprocating durable exercise test, its specification size need decide according to tested product, therefore without ready-made purchase, need customization or self-control.
When existing electronic product does durable vibration or to-and-fro movement test, tested product is fixed on platform central area, because various product has irregular structure to cause centre-of gravity shift and exists product ontology to form certain impulsive force and the problem of reacting force to work top.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of long duration test damping frock, this frock can cause centre-of gravity shift to irregular structure, make it reach balance by adjusting directions X and Y-direction balance screw rod, can eliminate product ontology work top is formed to certain impulsive force and the problem of reacting force simultaneously
The technical solution adopted in the present invention is:
A kind of long duration test damping frock, comprise flat board is installed, four jiaos that flat board is installed are equipped with shock-absorbing suspension column, install in dull and stereotyped two sides directions X, Y-direction and be respectively equipped with a through hole, through hole top-bottom cross in directions X, Y-direction keeps cross structure, and two balance screw rods are respectively charged in the through hole in directions X, Y-direction; Set nut is equipped with respectively at balance screw rod two ends, installs on flat board and has installation fixing threaded hole.
Shock-absorbing suspension column is made up of pagoda spring, sheath, spring lower seat and the spring seat of honour; Sheath is equipped with in the outside of pagoda spring, and spring lower seat is equipped with in the lower end of pagoda spring, and the spring seat of honour is equipped with in upper end, and the spring seat of honour is connected with installation flat board.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention makes it reach balance by adjusting directions X and Y-direction balance screw rod, can eliminate product ontology work top is formed to certain impulsive force and the problem of reacting force simultaneously, and the present invention is simultaneously simple in structure, durable in use, cheap.
Brief description of the drawings
Fig. 1 is front view of the present invention;
Fig. 2 is fundamental diagram of the present invention.
In figure: 1-installs flat board, 2-installs fixing threaded hole, 3-balance screw rod, 4-through hole, 5-set nut, 6-pagoda spring, 7-sheath, 8-spring lower seat, the 9-spring seat of honour, 10-shock-absorbing suspension column, 11-proportion magnetic valve, 12-solenoid, 13-iron core, 14-spool.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figure 1, a kind of long duration test damping frock, comprise and install dull and stereotyped 1, four jiaos that flat board 1 is installed are equipped with shock-absorbing suspension column 10, install in dull and stereotyped 1 two sides directions X, Y-direction and be respectively equipped with a through hole 4, through hole 4 top-bottom cross in directions X, Y-direction keep cross structure, and two balance screw rods 3 are respectively charged in the through hole 4 in directions X, Y-direction; Set nut 5 is equipped with respectively at balance screw rod 3 two ends, installs on dull and stereotyped 1 and has the fixing threaded hole 2 of installation, and fixing threaded hole 2, for fixing tested product, is installed dull and stereotyped 1 and determined size and thickness according to electronic product size.
Shock-absorbing suspension column 10 is made up of pagoda spring 6, sheath 7, spring lower seat 8 and the spring seat of honour 9; Sheath 7 is equipped with in the outside of pagoda spring 6, and spring lower seat 8 is equipped with in the lower end of pagoda spring 6, and the spring seat of honour 9 is equipped with in upper end, and the spring seat of honour 9 is connected with installation dull and stereotyped 1.
Cause centre-of gravity shift because various product has irregular structure, adjust directions X and Y-direction balance screw rod and make it reach balance.
Take the proportion magnetic valve in motor car engine as example as tested product below, the principle of work of this frock be described further, see accompanying drawing 2:
Proportion magnetic valve 11 in motor car engine is in the time of normal work, do the to-and-fro movement of upper frequency, and engine is arranged on vehicle frame by antivibration pad, this worktable need be simulated the normal work operating mode of proportion magnetic valve 11 as far as possible, tested product proportion magnetic valve 11 use are installed to fixing threaded hole 2 and be fixed on the central area of installing on dull and stereotyped 1, at this moment adjust directions X and Y-direction balance screw rod 3 makes it reach balance, nut 5 is locked, proportion magnetic valve 11 setting in motions, in valve, iron core 13 moves up and down and is with movable valve plug 14 to open and close, iron core 13 is reciprocating under solenoid 12 effects, make product form certain impulsive force to work top, impulsive force is delivered on four shock-absorbing suspension columns 10 through pagoda spring 6 shock absorbing bufferings by table top, eliminate impulsive force and reacting force, reach the realistic simulation valve seat operating mode of normally working, meet testing requirements.
The maximum feature of the present invention is to eliminate the pump reacting force of the impulsive force to work top of bringing of proportion magnetic valve 11, effectively remove the assorted focus of reacting force to valve body, noise is little simultaneously, when test, frock does not move, the correctness of warranty test preferably, and principle is clear and definite, simple in structure, plate material is installed and is adopted steel plate, durable in use, cheap.
