Detailed description of the invention
Fig. 1 is the structural schematic diagram of outer L shape ring forging fitting surface detecting tool of the present invention.
Fig. 2 is the enlarged structure schematic diagram in Fig. 1 at A.
Specific embodiment
The present invention is described in further detail with attached drawing combined with specific embodiments below.
As shown in Figure 1 and Figure 2, outer L shape ring forging fitting surface detecting tool, comprising: outer 9 outside of L shape ring forging can be located on
1,12 detection pin rod 2 of annular pattern, the lower part of annular 1 inner ring side wall of pattern be provided with for outer L shape ring forging 9
The annular detection faces 11 that fitting surface on the side wall of outer ring fits circumferentially are evenly arranged with 12 on annular pattern 1
For the one-to-one dowel hole 12 from lower insertion of each detection pin rod 2, each dowel hole 12 is led under by upper limit hole 121
It is formed to hole 122, the diameter in upper limit hole 121 is less than the diameter of lower pilot hole 122, and the middle part of each detection pin rod 2 is respectively provided with
There are the annular guide ledges 21 that guiding can be matched with the lower pilot hole 122 in corresponding dowel hole 12, each detection
The top of pin rod 2 can be inserted into the upper limit hole 121 of corresponding dowel hole 12, and upper limit hole 121 and detection
Fit clearance between 2 top of pin rod is not more than 0.2mm, preferably no greater than 0.1mm, and fit clearance, which crosses conference, to be made to detect pin rod 2
It tilts excessive, thus will affect the accuracy of detection, be provided with a detection step on the top of each detection pin rod 2
22。
In the present embodiment, it is uniformly arranged on annular pattern 1 there are four threaded hole is lifted, setting in this way facilitates hoisting ring
Shape pattern 1.
It is provided with a circle reinforcing ring 3 on the side wall of annular 1 outer ring of pattern, setting in this way is annular pattern 1 in order to prevent
Deform warpage.
