Description
Technical field
The utility model relates to a kind of auto parts and components testing fixture, a kind of for circulatory spherical hydraulic power-assisted steering gear rocking arm centre distance and directional bond angle testing fixture specifically, belongs to Automobile Parts Inspection equipment field.
Background technology
Rocking arm, as the end fitting of circulatory spherical hydraulic power-assisted steering gear, plays the key effect that steering gear power output is passed to car load, and its poor quality directly affects the normal use of automobile.On rocking arm, have two significant dimensions, one is taper hole and cone spline centre distance L, and another is directional bond angle A, as shown in Figure 1.L is excessive or too small for rocking arm centre distance size, can cause steering gear to install with entrucking; Rocking arm size A is excessive or too small, can cause car load both sides to turn to not of uniform size.As can be seen here, in process, carrying out size L and A checks very important.From rocker structure, check that centre distance size L and directional bond angle A are all cumbersome, current inspection centre distance size L is used is three-coordinates measuring machine, what check that directional bond Angular Dimension A uses is projector, these two kinds of test modes can only be used in the place of quality department appointment, and many unacceptable products have been caused because can not check in time in production scene.
Utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, proposes a kind ofly for rocking arm centre distance and directional bond angle testing fixture, can check fast, accurately rocking arm centre distance and directional bond angle, improves the qualification rate of product.
In order to solve above technical matters, it is a kind of for rocking arm centre distance and directional bond angle testing fixture that the utility model provides, comprise the stationary installation and the pick-up unit that are arranged on the rocking arm on base plate, described stationary installation comprises the round plug of fixing rocking arm taper hole and the fixing square plug of rocking arm cone splined hole; Described pick-up unit comprises the scale that reads centre distance and the index dial that reads directional bond angle, described index dial and scale are installed on described base plate, described index dial is arranged on one end of described base plate by rotating rotating shaft, described base plate is provided with the scale mark corresponding with described index dial, and on described index dial, be provided with mandrel and be fixedly connected with described side's plug, on described side's plug, be socketed with cylindrical with the spline housing of guide slot; One side of described scale is provided with the scale clamp sliding along described scale, and described scale clamp is provided with in scale mark corresponding to described scale, and described round plug is vertically plugged in described scale clamp.
The technical scheme that the utility model further limits is: aforesaid for rocking arm centre distance and directional bond angle testing fixture, described spline housing center has the square hole mating with described side's plug, the long limit of described guide slot and described square hole central vertical, comprise square mandrel outer profile is made to rectangular structure, its objective is and guarantee that directional bond position when checking is unique.
Aforesaid for rocking arm centre distance and directional bond angle testing fixture, between described rotating shaft and described base plate, by pair of bearings, be connected.
Aforesaid for rocking arm centre distance and directional bond angle testing fixture, because the tolerance range of rocking arm centre distance size L is 6mm, therefore the minimum division value of described scale is set to 1mm.
Further, aforesaid for rocking arm centre distance and directional bond angle testing fixture, because the tolerance range of rocking arm directional bond Angular Dimension A is 3 °, therefore the minimum division value of described index dial is set to 0.5 °.
The beneficial effects of the utility model are: the utility model adopts circle plug and square plug to support rocking arm, by fixedly centre distance numerical value is measured at rocking arm cone spline center, adjusting taper hole center; By fixedly rocking arm cone spline center, directional bond position and adjustment rocking arm steering angle are measured directional bond angle numerical value.The utility model, by measuring fast, accurately, provides guarantee for producing field process control, has greatly reduced the appearance of waste product.
