Define.
Referring to Fig. 1, the utility model embodiment includes：
A kind of Ceramic shaft sleeve sintering jig is used in the sintering process of Ceramic shaft sleeve, including：Bottom tray 1, fitly
Be arranged in the bottom tray 1 for place and support Ceramic shaft sleeve 4 to be sintered several trays 2 and for pair
Several spacer blocks 3 being placed between two neighboring tray 2 that Ceramic shaft sleeve 4 to be sintered limits, several trays 2 are strip
The circular groove 21 for placing Ceramic shaft sleeve 4 to be sintered is contained on shape, top, containing there are two shape of ears on several spacer blocks 3
Arc-shaped convex 31, the arc-shaped convex 31 matches with the circular groove 21, and the circular groove 21
Diameter is less than the outer diameter of Ceramic shaft sleeve 4 to be sintered so that the ceramic shaft to be sintered being placed in the circular groove 21
Set 4 has with 21 surface of the circular groove and only there are two contact point, reduces resistance so that shunk when sintering it is smooth uniformly,
The roundness of the Ceramic shaft sleeve 4 sintered is good, there is no sintering defective products.
Several trays 2 are arranged at several spacer blocks 3 in the bottom tray 1 from level to level.
The material of several trays 2 and several spacer blocks 3 is sintered ceramic material.
