Abstract
The utility model provides a kind of control arm rubber bushing fatigue test flexible fixture, solve chuck body poor compatibility and reverse actuator technical problem that fixture is caused a deviation to cross torsion power testing result, this it comprise the chuck body be arranged on base, longitudinal supporting plate and cross-brace plate, cross-brace plate is provided with power transmission shaft, its technical essential is: chuck body is butted into the clamping part of annular with two semicircular ring, in annular clamping part, be set with cylindrical collar; Steering assembly is connected with in the end of described power transmission shaft, avoid changing chuck body, decrease dismounting operation, reduce the installation difficulty of operating personnel, improve operating efficiency and save the cost of fixture, and by the steering assembly at increase cross-brace plate power transmission shaft, the torsion that torsion actuator can be made to apply fixture is consistent with power transmission shaft direction, reduces deviation, improves precision and the accuracy of detection, its structure is simple, easy to operate.
Description
Technical field
The utility model relates to automobile component detection fixture, particularly a kind of control arm rubber bushing fatigue test flexible fixture.
Background technology
In the process of moving, the control arm on fore sub frame can be subject to three power effects to car: side force, longitudinal force and vertical force.And control arm back bush is mainly by longitudinal force and cross torsion.For the actual road conditions of simulating vehicle, need to rely on fixture realize the radial direction of lining and swing stressed.The actual power be subject to of lining is delivered to fixture by linear actuator and torsion actuator, is then delivered on lining.
Existing fixture comprises chuck body, base, longitudinal supporting plate and cross-brace plate, linear actuator acts on longitudinal supporting plate, reverse actuator and act on cross-brace plate, during detection, lining is by being installed in chuck body, for the lining of different size, need the chuck body changing corresponding size, add operation and cost increase, inefficiency, and due to reverse the force direction of actuator and cross-brace plate rotating shaft not on the same axis, add component clamp body being produced to other directions except twisting resistance, make to affect testing result to cause a deviation.
Summary of the invention
The purpose of this utility model is to provide a kind of control arm rubber bushing fatigue test flexible fixture.Solve chuck body poor compatibility and reverse the technical problem that causes a deviation to cross torsion power testing result to fixture of actuator, its structure is simple, avoids changing chuck body, and improves the accuracy reversing actuator twisting resistance direction of transfer.
The technical scheme that the utility model adopts is: this control arm rubber bushing fatigue test flexible frock fixture comprises the chuck body be arranged on base, longitudinal supporting plate and cross-brace plate, cross-brace plate is provided with power transmission shaft, its technical essential is: chuck body is butted into the clamping part of annular with two semicircular ring, in annular clamping part, be set with cylindrical collar; Steering assembly is connected with in the end of described power transmission shaft.
Described steering assembly is the connecting rod being provided with universal joint at two ends, is fixedly connected with power transmission shaft by the universal joint of one end.
The advantage that the utility model has and good effect are: owing to arranging cylindrical collar in chuck body, by changing the cylindrical collar of cooperation corresponding with detected lining, avoid changing chuck body, decrease dismounting operation, reduce the installation difficulty of operating personnel, improve operating efficiency and save the cost of fixture, and by the steering assembly at increase cross-brace plate power transmission shaft, the torsion that torsion actuator can be made to apply fixture is consistent with power transmission shaft direction, reduce deviation, improve precision and the accuracy of detection, its structure is simple, easy to operate.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is chuck body portion structural representation;
Fig. 3 is the structural representation of the collar;
Fig. 4 is detected bush structure schematic diagram.
In figure, sequence number illustrates: 1 longitudinal supporting plate, 2 collars, 3 cross-brace plates, 4 chuck body, 5 bases, 6 bearings, 7 power transmission shafts, 8 steering assemblies, 9 support bars, 10 set bolts, 11 linings.
Detailed description of the invention
Should be readily appreciated that to make the utility model, concrete structure of the present utility model is described in detail according to Fig. 1 to 4, embodiment: as illustrated in fig. 1 and 2, a kind of control arm rubber bushing fatigue test flexible fixture, comprise the chuck body 4 be arranged on base, longitudinal supporting plate 1 and cross-brace plate 3, chuck body is bolted on base 5, cross-brace plate 3 is provided with the power transmission shaft 7 of bolt and bearing 6 connection, chuck body 4 is butted into the clamping part of annular with two semicircular ring, is set with cylindrical collar 2 in annular clamping part; Be connected with steering assembly 8 in the end of power transmission shaft 7, steering assembly is the connecting rod being provided with universal joint at two ends, is fixedly connected with power transmission shaft by the universal joint of one end, and longitudinal supporting plate 1 is provided with support bar 9 for mounting bush 11 and set bolt 10.As shown in Figure 3, lining as shown in Figure 4 for cylindrical collar 2.
The course of work: in the chuck body that the collar 2 with detected lining 11 corresponding matching is installed, then lining 11 is put into the collar 2, by set bolt 10, lining is fixed, longitudinal supporting plate is connected with longitudinal actuator, and horizontal actuator and steering assembly, detect, can by changing the lining of different size with the different lining of correspondence, the external diameter of the lining of same specification is all identical, need not change chuck body, realizes the detection to lining.
