Description
Technical field
The utility model relates to a kind of coupling arrangement, particularly in a kind of automobile cab vibrations experiment, for the transition connecting apparatus by linking together between six-degree of freedom vibration table top and pilothouse.
Background technology
The six degree of freedom test-bed table top that carries out the test pavement simulating vibration test for the counterweight card pilothouse certain tapped blind hole of pitch-row that distributing, and the connected mode more complicated of cab mounting and vehicle frame, both can not directly be connected.Therefore, be badly in need of wanting a kind of excessive frock that pilothouse and table top are rigidly connected, in order to carry out vibration test.
The utility model content
For deficiency of the prior art, the utility model aims to provide a kind of automobile cab vibration test transition connecting apparatus of special use, for pilothouse and vibrations experiments table top is firm, be rigidly connected to together with.
In order to address the above problem, this kind of automobile cab vibration test transition connecting apparatus is characterized in that comprising: two longitudinal beams, be arranged on the frame cross between longitudinal beam, two drive end brackets, carriage crossbeam and a plurality of hold-down supports;
Every drive end bracket respectively is connected with the outside of a longitudinal beam, and the free end of two drive end brackets connects by the carriage crossbeam; Hold-down support comprises base and be arranged on the joint face on base, and this joint face is connected with the sidewall of longitudinal beam or drive end bracket, and base is connected with vibration table.
Preferably, between described longitudinal beam and drive end bracket, between drive end bracket and carriage crossbeam, be bolted; Evenly be provided with four connecting holes on the joint face of described hold-down support, be connected for the sidewall bolt with longitudinal beam or drive end bracket.Described connecting hole is slotted hole.
Preferably, the quantity of described hold-down support is four, and two are connected with longitudinal beam, and two are connected with drive end bracket.
Preferably, the base of described hold-down support is provided with back-up block, and this back-up block is provided with described joint face, between joint face and back-up block, is provided with reinforcement.
More preferably, the distance between described two drive end brackets is greater than the distance between described two longitudinal beams.
The beneficial effects of the utility model are: pilothouse and table top can be rigidly connected by applying this transition connecting tooling, solve the technical matters on the test tool.Its stabilized structure is reliable, improves experiment effect.
The accompanying drawing explanation
The structural representation that Fig. 1 is automobile cab vibration test transition connecting apparatus of the present utility model;
The another structural representation that Fig. 2 is automobile cab vibration test transition connecting apparatus of the present utility model;
The structural representation that Fig. 3 is hold-down support of the present utility model;
The another structural representation that Fig. 4 is hold-down support of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
In conjunction with Fig. 1 and Fig. 2, this kind of automobile cab vibration test transition connecting apparatus comprises: two longitudinal beams 2, be arranged on two frame cross between longitudinal beam 1, two drive end brackets 3, carriage crossbeam 4 and four hold-down supports 5.In order to guarantee that this frock is identical with the rigidity of true vehicle frame as far as possible, the material of selection is with the size of steel plate all with actual identical, and every drive end bracket 3 respectively is connected with the outside of a longitudinal beam, and the free end of two drive end brackets connects by carriage crossbeam 4.For the ease of dismounting and transportation, between described longitudinal beam 2 and drive end bracket 3, be bolted between drive end bracket 3 and carriage crossbeam 4.Wherein two hold-down supports 5 are arranged on the both sides of longitudinal beam, and two other is arranged on the both sides of drive end bracket.Due to the front overhang of pilothouse, from being slightly larger than the rear overhang distance, so two drive end brackets distances are greater than two longeron distances, the distance between two drive end brackets 3 is greater than the distance between described two longitudinal beams 2.
As shown in Figure 3 and Figure 4, each hold-down support 5 comprises base 51 and is arranged on the joint face 52 on base, evenly is provided with four connecting hole 5a on joint face 52, for the sidewall bolt with longitudinal beam or drive end bracket, is connected, and base 51 is connected with vibration table.In addition, in order to make to there is certain distance between this device and shaking table, be provided with back-up block 53 between the base of hold-down support 5 and joint face, this back-up block is provided with joint face 52, be provided with reinforcement 54 between joint face 52 and back-up block 53, guarantee stability and framework fastness that it is made.Described connecting hole 5a is slotted hole, and slotted hole is in order to compensate mismachining tolerance.So just realized being rigidly connected of pilothouse and test-bed table top.
The use procedure of this frock is as follows:
1, two longerons are connected with bolt with outside crossbeam, bolt is not tightened, and is convenient to adjust;
2, inboard crossbeam is connected with bolt with longeron, bolt is not tightened equally;
3, two front racks are connected with bolt with two longerons respectively, by bolt tightening;
4, carriage crossbeam two ends are connected with front rack, tight a bolt;
5,, the bolt tightening of the outside and inboard crossbeam, vehicle frame front end assembly has been assembled as Fig. 1;
6, the vehicle frame front end assembly installed is placed on bearing, adjusts support position to best simultaneously;
7, with bolt, bearing is connected with vehicle frame front end assembly, does not tight a bolt;
8, whole frock is placed on test-bed, aligned position, be bolted together;
9, tighten the bolt of bearing and vehicle frame front end assembly, as shown in Figure 1;
10, by suspending before and after pilothouse, with frock, be connected, then pilothouse is connected with suspending.
After installation, check whether all link positions connect intact, guarantee that bolt can not become flexible.
