Description
Technical field
The utility model relates to the paired fatigue tester of a kind of thrust rod ball hinge.
Background technology
Distance rod forms primarily of bulb, ball pivot and sleeve pipe, automobile is when starting, accelerating and braking, rubber bushing is frequently subject to tension and compression, the ability of bearing tensile force due to rubber is poor, and rubber bushing in use, is the serviceable life of raising rubber bushing, when ball pivot is installed and used, make rubber be in its pre-compressed state, the size of pre compressed magnitude should ensure to bear less tensile force in ball pivot use procedure, carries out torture test extremely important to thrust rod ball hinge.
Utility model content
Technical problem to be solved in the utility model is to provide the paired fatigue tester of simple, easy to use, the efficient thrust rod ball hinge of a kind of structure.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: the paired fatigue tester of a kind of thrust rod ball hinge, comprise a horizontal support, horizontal in the middle part of described support have the cushion cap bearing a pair distance rod, described support one end is before before and after cushion cap respective end, symmetria bilateralis is fixed with, rear boss, the described support other end and one drives the U-shaped after making its bilateral reciprocation to clamp by hydraulic mechanism and is slidably matched, wherein the rear and front end of a distance rod mandrel passes across cushion cap and respectively with front, rear boss is connected through screw and nut assembly, the rear and front end of an other distance rod mandrel is through cushion cap and before clamping with U-shaped respectively, rear two-arm is connected through screw and nut assembly.
Further, described cushion cap and distance rod are transition fit.
Further, described hydraulic mechanism comprises hydraulic cylinder and output shaft.
Further, described support is provided with the counting module detecting U-shaped pincers front-rear reciprocation movement frequency, described cushion cap is provided with the pressure transducer in order to testing pressure, described hydraulic mechanism is also provided with the control module that hydraulic control mechanism provides cycling alternating load, described counting module, pressure transducer are all electrically connected with control module.
Compared with prior art, the utility model has following beneficial effect: the utility model structure is simple, easy to use, and can carry out torture test to paired thrust rod ball hinge, work efficiency is high.
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.

Embodiment
As shown in Figure 1 and 2, the paired fatigue tester of a kind of distance rod 2 ball pivot, comprise a horizontal support 1, horizontal in the middle part of described support 1 have the cushion cap 3 bearing a pair distance rod 2, described support 1 one end symmetria bilateralis before and after cushion cap 3 respective end is fixed with front boss 4, rear boss 5, described support 1 other end and one drives the U-shaped after making its bilateral reciprocation to clamp 7 by hydraulic mechanism 6 and is slidably matched, wherein the rear and front end of distance rod 2 mandrel 21 pass across cushion cap 3 and respectively with front boss 4, rear boss 5 is connected through screw and nut assembly 8, the rear and front end of other distance rod 2 mandrel 21 is passed cushion cap 3 and clamps 7 forearms 71 with U-shaped respectively, postbrachium 72 is connected through screw and nut assembly 8.When hydraulic mechanism 6 starts, drive U-shaped to clamp 7 bilateral reciprocation, now 7 to be threaded because mandrel 21 and the U-shaped of ball pivot clamps, cushion cap 3 and boss maintain static, described mandrel 21 is subject to the alternate load perpendicular to mandrel 21 length direction.
In the utility model, described cushion cap 3 is transition fit with distance rod 2.
In the utility model, described hydraulic mechanism 6 comprises hydraulic cylinder 61 and output shaft 62.
In the utility model, described support 1 is provided with detect the counting module 9 that U-shaped clamps 7 front-rear reciprocation movement frequencies, described cushion cap 3 is provided with the pressure transducer 10 in order to testing pressure, described hydraulic mechanism 6 is also provided with hydraulic control mechanism 6 to provide the control module 11 of cycling alternating load, described counting module 9, pressure transducer 10 are all electrically connected with control module 11.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
