Abstract

The utility model relates to a performance testing table for a luggage cabin cover, which comprises a testing table seat and a vertical frame. The vertical frame is fixedly arranged on the testing table seat, two adjusting suspending blocks are transversely and symmetrically arranged on the vertical frame, a pair of tested torsion rods and two symmetrical tested hinges are arranged at the lower parts of the adjusting suspending blocks in a suspending manner, and the distance between the two adjusting suspending blocks can be adjusted. The performance testing table realizes that one machine can finish detecting the opening-closing function of the luggage cabin cover and the fatigue resisting performance of the hinges and the torsion rods, which is beneficial for carrying out maintenance on detecting equipment, reduces the detecting cost of the luggage cabin cover, and is beneficial for increasing economic benefits.

Description

The baggage room hatchcover is performance test bed

Technical field

The utility model belongs to the Automobile Detection field, and it is performance test bed especially to relate to a kind of baggage room hatchcover.

Background technology

In the production run of car boot cabin hatchcover, need carry out Function detection to the unlatching of hatchcover, and its hinge and torsion bar are carried out the fatigue performance detection.The method that the open function of traditional car boot cabin hatchcover detects is after being installed in the car boot cabin on the automobile, the artificial hatchcover of opening, detect it and whether have damping action in certain angle, promptly hatchcover can rest on this position transfixion when opening a less angle; After hatchcover reached a certain angle, hatchcover can be opened under the effect of torsion bar elastic force automatically.The hinge of car boot cabin hatchcover and the fatigue performance detection method of torsion bar are that hinge and torsion bar are installed in respectively on the worktable, detect its fatigue performance separately.Said method has the following disadvantages:

If 1, there is the open function defective in mounted car boot cabin hatchcover, renew after being merely able to it is pulled down, not only waste time and energy, may also can automobile production be delayed because of changing these parts, cause bigger economic loss.

2, hinge and torsion bar are installed in respectively on the worktable, its fatigue performance when detecting its fatigue performance separately and can not objectively respond hinge and torsion bar associated working causes Monitoring Data inaccurate.

3, the open function detection of hatchcover and hinge, torsion bar fatigue performance detect needs to adopt multiple devices to detect, and has not only increased the workload of checkout equipment maintaining, has also increased the detection cost of baggage room hatchcover, is unfavorable for the raising of economic benefit.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art part, provide a kind of high efficiency, simple in structure, be easy to safeguard and detect that the baggage room hatchcover is performance test bed accurately.

The purpose of this utility model is achieved in that

A kind of baggage room hatchcover is performance test bed, it is characterized in that: comprise test pedestal, stand, on the test pedestal, install vertical frame, lateral symmetry is equipped with two adjustment and hangs piece on this vertical frame, the bottom of hanging piece in adjustment is lifted with a pair of tested torsion bar and two tested hinges of symmetry, and these two adjustment are hung the piece mutual spacing from adjustable.

And, the simulation crossbeam of a simulation hatchcover weight is installed between two tested hinges, to simulating an eccentric runner is being installed on the test pedestal under the crossbeam, this off-centre runner drives rotation by a drive motor that is packed in equally on the test pedestal, and eccentric runner is the upper end and simulation crossbeam hinge dress of crank radially.

And, in the radially side of eccentric runner one counter is installed.

Advantage of the present utility model and good effect are:

1, the utility model can detect the quality of hatchcover unlatching of car boot cabin and closing function before installation, has avoided baggage room to install the trouble that hatchcover is changed in the back, has saved manpower and materials.

2, the utility model real time modelling the hinge of baggage room and the package assembly of torsion bar, and this package assembly is installed on the test board, can be according to the fatigue performance of technical requirement continuous detecting baggage room under in working order, objective endurance data when obtaining true reflection hinge and torsion bar associated working, it is more accurate to detect data.

3, the utility model has realized that the keying Function detection of hatchcover and hinge, torsion bar fatigue performance detect a machine and finish, and not only helps the maintaining of checkout equipment, has also reduced the detection cost of baggage room hatchcover, helps the raising of economic benefit.

Embodiment

Be described in detail embodiment of the present utility model below in conjunction with accompanying drawing; Need to prove that present embodiment is narrative, is not determinate, can not limit protection domain of the present utility model with this.

A kind of baggage room hatchcover is performance test bed, comprise test pedestal 9, stand 8 and tested torsion bar 2, tested hinge 1, on the test pedestal, install vertical frame, lateral symmetry is equipped with to adjust and hangs piece 6 on this vertical frame, these two adjustment are hung in can be on the vertical frame made cross through hole 10 of piece and are laterally adjusted mutual distance by bolt 11, to adapt to the baggage room hatchcover of different spans, different size.The bottom of hanging piece two adjustment all is lifted with a pair of tested torsion bar jointly, this to the two ends of tested torsion bar separately symmetry be hinged with tested hinge, the hinge dress of tested torsion bar and tested hinge is simulated the installation of baggage room hatchcover and car body fully and is subjected to force mode.

Come the embodiment of utility model below by the functional test of baggage room hatchcover and the testing fatigue of tested torsion bar:

1, the functional test of baggage room hatchcover

Piece is hung in the adjustment of at first regulating on the crossbeam, the width of itself and baggage room hatchcover is adapted, the two ends of baggage room hatchcover are installed on the hinge of both sides by bolt, just turn the baggage room hatchcover this moment, the on off state of imitation baggage room hatchcover, detect hatchcover and whether meet technical requirement, and hatchcover is opened after arriving set angle automatically, thereby can detect the keying function of baggage room hatchcover comprehensively meticulously in the damping action of different orientation angles.

2, the testing fatigue of tested torsion bar

When hinge that carries out the baggage room hatchcover and the detection of torsion bar fatigue performance, hatchcover is unloaded, the simulation crossbeam 7 of a simulation hatchcover weight is installed between two hinges; Simultaneously, to simulating an eccentric runner 5 is being installed on the test pedestal under the crossbeam, this off-centre runner drives rotation by a drive motor 12 that is packed in equally on the test pedestal, eccentric runner is the upper end and simulation crossbeam hinge dress of crank 4 radially, realize that eccentric runner drives radially crank and does and pump, tested torsion bar reversed torsion can be simulated the fatigue behaviour that causes tested torsion bar along with the repeated open of hatchcover thus.For the tired situation that writes down tested torsion bar corresponding hatchcover to open number of times right, in the radially side of eccentric runner one counter 3 is installed.
