Given a quadratic function $y=ax^{2}-4ax+3+b\left(a\neq 0\right)$.  
$(1)$ Find the axis of symmetry of the graph of the quadratic function;  
$(2)$ If the graph of the quadratic function passes through the point $\left(1,3\right)$, and the integers $a$ and $b$ satisfy $4 \lt a+|b| \lt 9$, find the expression of the quadratic function;  
$(3)$ Under the conditions of $(2)$ and $a \gt 0$, when $t\leqslant x\leqslant t+1$ the function has a minimum value of $\frac{3}{2}$, find the value of $t$.
