Test board comprises base 2 and bearing 3, and wherein: base 2 is supported on the bottom surface through four bight lower margins 1; Bearing 3 is installed on the centre of base 2; Seat 5 to be tested is carried on the bearing 3, and can be by bearing 3 adjustment test positions.
Mounting bracket comprises left and right column 8 and crossbeam 19, and wherein: left and right column 8 is fixed on the base 2 of test board; The two ends of crossbeam 19 are set up on the top of left and right column 8, so that the associated components of elevating mechanism is installed; Also can adopt a plurality of columns, they are separately fixed at the bight of base, fix with lateral tie between the column, constitute firm mounting bracket thus.
Elevating mechanism comprises lifting arm 10 and cylinder 16, and wherein lifting arm 10 is installed clamping part 4; The cylinder body of cylinder 16 is installed on the mounting bracket, specifically is to be supported on the left and right column 8 through cylinder block 15; Piston rod 13 connects lifting arm 10 through cylinder joint 9, when piston rod 13 stretches, drives clamping parts 4 actions through lifting arm 10.A kind of optimal way is, at the two ends of lifting arm 10 guide shaft 12 is installed respectively, and this two guide shaft 12 can freely on mounting bracket vertically slide, and guarantees that thus clamping part 4 application of force directions are stable.
The main body of clamping part 4 is a U type composite pad, the leading edge that can make things convenient for, clamp seat 5 reliably.This clamping part 4 is 6 fixing with lifting arm 10 through clamping, and 6 the installation position of clamping is equipped with sensor 7, is convenient to detect in real time test parameters and supplies control system to handle.
As shown in Figure 1, wear screw mandrel 14 respectively at the two ends of cylinder block 15, the lower end of this two screw mandrel 14 is supported on the supporting seat 11 of left and right column 3, and the upper end then is connected to control hand wheel 17, so that the height and position of adjustment cylinder 16.At this moment, some tightener sprockets 18 are set on the crossbeam 19 of mounting bracket correspondingly also, they are located between two screw mandrels, the 14 set sprocket wheels, and cylinder 16 just can be stablized through cylinder block 15 with 14 tensionings of two screw mandrels thus in winding chain (scheming not shown) back.
Using under cylinder 16 situation, also be provided with the air bigeminy part 23 of pneumatic connection cylinder, can be loaded on the right column 3 through back up pad 22 simply, so that simplified structure.In addition, strength display 20 and control box 21 are installed on column 3 also, so that show load condition and real-time monitoring test process.
Explanation is in passing, also can oil cylinder in the present embodiment, multiple mode such as electric pushrod replaces cylinder 16, as long as can apply the external force of vertical direction, repeat no more at this to clamping part.
Seat is vertically being pulled up on the basis that the aptitude tests apparatus structure describes with anti-, below the utility model seat is briefly being described with the anti-test process that vertically pulls up the aptitude tests device.
Referring to Fig. 2, expression the utility model seat is vertical with the anti-test process that vertically pulls up the aptitude tests device, specifically may further comprise the steps:
S301, fixing test seat.
S302, adjusting clamp component locations, make clamping part be sandwiched in test seat leading edge center.
Through above-mentioned steps S301, S302, accomplish the preceding preparation of test.
S303, vertically force in the test seat position to be tested.
S304, logging test results.
Comprise the each clamping part application of force size of record, seat deformation situation etc., supply subsequent quantizatiion to analyze seat intensity.
Whether S305, judgement test seat are out of shape or break,
If get into step S307;
If not, get into step S306.
S306, judge whether to reach preset test number (TN),
If get into step S307;
If not, return step S303.
S307, end test.
The fixing test seat, and regulate the clamping component locations, make clamping part be sandwiched in test seat leading edge center;
Repeated vertical forces in the position to be tested of test seat, as if being out of shape at preset test number (TN) build-in test seat or breaking, judges that the test seat is through testing; Otherwise, judge that the test seat is not through test
In the above-mentioned method of testing, the structure of clamping part, use anti-force application location, size and the retention time etc. that vertically pull up aptitude tests to be key element.Below be the concrete method of testing of a plastic seat: clamping part 4 is that a rectangle composite pad constitutes, and can accomplish pulling up test through the action of elevating mechanism; Plastic seat 5 is installed on the test board, regulates the position of composite pad, make it force in seat leading edge center; Application of force direction is perpendicular to seat 5, and size is 1000 ± 50N, and the application of force kept 30 seconds, repeats 10 times, and is each at interval more than 30 seconds; If plastic seat 5 outwardly sounds, nothing is out of shape or is broken, then through test, otherwise for not passing through.
The utility model seat applies external force with the anti-aptitude tests device that vertically pulls up through clamping part; Can test the anti-intensity that pulls up of seat vertical direction; This helps to set up unified testing standard, with the complete detection performance of products, improves the safety of products coefficient.This method of testing simple and fast is convenient to operation, thereby is had application promise in clinical practice.
Only be the preferred implementation of the utility model below, should be pointed out that above-mentioned preferred implementation should not be regarded as the restriction to the utility model, the protection domain of the utility model should be as the criterion with claim institute restricted portion.For those skilled in the art, in spirit that does not break away from the utility model and scope, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
