Summary of the invention
The purpose of this utility model is to provide a kind of novel powder metallurgical car steering tube column movable stand, and it adopts powder metallurgy process to make, and can be used for producing in enormous quantities, and the manufacturing efficiency height is removed machining from when reaching product requirement.
For reaching above-mentioned purpose, the utility model adopts following technological scheme:
A kind of powder metallurgy automobile gearbox input rack comprises by sintering flange connecting and support, flange have flange body be connected with the center that is arranged at the flange body center perforate with along the center drilling periphery equally distributed be connected lateral opening; Support has rack body, protrude in the double wedge of rack body outer wall, be arranged at the rack body center be connected center fixation hole that perforate is communicated with and the first fixedly fixedly perforate of perforate and second that evenly is arranged at described fixed hole outer wall with described center.
Described center fixation hole is cylindric, has place's arcuation on the cylinder perisporium and gives prominence to.
The described second fixing perforate keyway that comprise circular hole and outwards protrude out along the Circularhole diameter two ends.
The Separating force that described flange is connected with support is 10000N.
The relative position degree of described flange and support is 0.20mm.
Described flange and the support parallelism in the working zone is 0.175mm.
Advantage of the present utility model is:
(1) compare with traditional technology, this input rack work efficiency increases substantially, and has advantages such as material economy, resource consumption are few.
(2) this input rack is compared with the normal sintering soldering tech, once finish sintering and soldering, the energy loss of having saved significantly.
(3) this input rack product precision height can satisfy user assembled requirement.
