Description
Technical field
The utility model relates to a kind of vehicle steering frequency test positioning tool, is used for to the steering wheel location, so that travel direction dish frequency test.
Background technology
At present, nearly all there is the idling jitter problem in the steering wheel of each vehicle on the market, except to the car load engine, turn to be and other subsystem or parts analysis, also to be controlled steering wheel rigidity.Therefore, need locate steering wheel by test fixture, carry out frequency detecting with frequency spectrograph then.Existing three kinds of different test fixtures are using, but all there are various defectives in they, as method one: adopt vice to clamp the outstanding spline of steering wheel, the bad fixed-direction dish of the method, and test result is also unstable; Method two: make steering wheel be in free state, namely place on the soft sponge with free suspension method or with steering wheel, result and data that producer gives that the method draws are too wide in the gap, and the restrained condition that applies lacks confidence level with row is interior inconsistent at present; Method three: with the big iron that is equivalent to several times of steering wheel weight, its center tubing string of burn-oning fixes steering wheel, and the method is not suitable for the steering wheel of different size, the test of whenever the doing a vehicle different tubing string of all need burn-oning, operating quite bothers, and can increase production cost greatly.
The utility model content
It is a kind of simple, convenient that technical problem to be solved in the utility model is to provide, and the good vehicle steering frequency test positioning tool of versatility.
The technical solution of the utility model is as follows: a kind of vehicle steering frequency test positioning tool, location-plate (1) is the rectangular flat structure, have screwed hole (3) in the center of location-plate (1), the place, four angles of described location-plate (1) is equipped with feet (2), the upper end of this feet (2) and location-plate (1) fix, the lower end of feet (2) is fixed on the upper face of gripper shoe (4), described gripper shoe (4) is corresponding one by one with feet (2), and gripper shoe (4) parallels with location-plate (1).
When the utility model is used for the steering wheel frequency test, only need steering wheel to be tested is placed on the location-plate, the screwed hole of the spline housing that makes steering wheel central authorities on the location-plate, pass the steering wheel spline housing with bolt then and screw in the screwed hole of location-plate, steering wheel and location-plate can be linked together, realize the location of steering wheel, relend and help frequency spectrograph just can carry out dependence test.The utility model is simple in structure on the one hand, and processing and fabricating is easy, can save production cost; On the other hand, the dismounting steering wheel is not only convenient but also quick on the utility model, can make the operation of steering wheel frequency test simpler, and testing efficiency is higher.The utility model supports on the ground by four gripper shoes, can guarantee that whole device keeps stable in test process; Make that by given bolt pretightening steering wheel is fixed in the test process, not only guaranteed precision of test result, and gone for different types of steering wheel that versatility is good.
Described feet (2) is angle steel, and the upper end of this feet (2) coats the corresponding angles of location-plate (1), and fixing by welding.Above structure feet selection on the one hand is convenient, and cost is low, and structural strength is good, can not deform or damage; On the other hand, the contact area between feet and the location-plate is big, and both connections not only firmly but also reliable.
Be provided with the fixed head (6) that parallels with it in the below of described location-plate (1), the shape size of this fixed head (6) adapts with location-plate (1), four angles of described fixed head (6) are stretched in the angle of corresponding feet (2), and are fixing by welding between fixed head (6) and the feet (2).Fixed head can increase the weight of whole device, shakes when preventing from testing, and has effectively avoided the influence to test result; Contact area is big between fixed head and the feet, and it is firm to connect.
Selection for convenience further reduces production costs, and described location-plate (1) is made by the identical steel plate of thickness with fixed head (6).
Described gripper shoe (4) is made by rectangular steel plates, and the contact area on gripper shoe and ground is big like this, can guarantee the stable support to whole device; Have installing hole (5) in gripper shoe (4), fot screw passes this installing hole can make gripper shoe and the earth be connected, thereby has guaranteed that further whole device keeps stable in test process.
Shake during for fear of test, the weight of described vehicle steering frequency test positioning tool is 5-10 times of square plate to be tested.
Beneficial effect: the utility model can be not only quick and convenient but also accurately stably realize the steering wheel frequency test, has simple in structure, characteristics such as production cost is low, simple operation, testing efficiency height, all is suitable for for polytype steering wheel.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is use state diagram of the present utility model;
Fig. 3 is partial sectional view of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, the utility model is made of location-plate 1, feet 2, gripper shoe 4 and fixed head 6 etc.Wherein, location-plate 1 is the rectangular flat structure, has screwed hole 3 in the center of location-plate 1, and this screwed hole 3 connects the upper and lower plates face of location-plate 1, and the center line of screwed hole 3 is perpendicular to the plate face of location-plate 1.Place, four angles at described location-plate 1 is equipped with feet 2, and this feet 2 is angle steel, and the upper end of feet 2 coats the corresponding angles of location-plate 1, and fixing by welding.Be equipped with a gripper shoe 4 below each feet 2, gripper shoe 4 is made by rectangular steel plates, and gripper shoe 4 parallels with location-plate 1, and the upper face of described gripper shoe 4 welds fixing with the lower end of corresponding feet 2 mutually.Have installing hole 5 in described gripper shoe 4, this installing hole 5 connects the upper and lower plates face of gripper shoe 4, and fot screw passes this installing hole 5, and gripper shoe 4 and the earth are fixed together.
