A fork-frame part

The drawing and machining of the fork-frame connecting plate are relatively complex, as it features structural elements such as multiple sets of holes, circular arc transitions, and irregularly shaped connecting parts. Let me demonstrate how to draw this blueprint.

The drawing and machining of the fork
frame [music] connecting plate are
relatively complex as it features
structural elements such as [music]
multiple sets of holes, circular arc
transitions, and irregularly shaped
connecting [music] parts. Let me
demonstrate how to draw this blueprint.
Draw concentric circles with radi of
21.5 and 34 respectively. [music]
>> [music]
>> Draw a straight line starting from point
O with an X direction offset of minus 57
[music] and a Y direction offset of 8.
Draw concentric circles with radi of
13.5 and 8 respectively. [music]
Draw a vertical line segment of
arbitrary length as shown in the figure.
Draw a straight line starting from point
O with an X direction offset of minus 36
and a Y direction offset of minus 88.
[music]
Continue drawing a 56 unit long straight
line to the right. Delete redundant line
segments. Draw a 30 [music] unit long
straight line upward.
Offset line of 30 units to the right.
Offset line be 65 units upward.
Use the extend command. [music]
Trim the drawing.
Delete redundant line segments.
Draw a circle with a radius of 15
centered at point A. [music]
Draw a circle with a radius of 15
centered at point B.
Delete redundant line segments.
Draw a 15 [music] unit long straight
line to the left.
Draw a circle with a radius of 15
[music] centered at point C.
Delete redundant line segments.
Use the ttr command to draw a circle
with a radius of 45.
Trim [music] the drawing.

[music]
Draw a common tangent line to the two
circles as shown in the figure.
Draw a straight line starting from point
O with an X direction offset of minus3
and a Y direction offset of -74.
Draw concentric [music] circles with
radi of 4.5 and 7.5 respectively
centered at the end point of the [music]
line.
Delete redundant line segments.
[music]
Draw a common tangent line to the two
circles as shown in the figure. [music]
Draw a straight line upward as shown in
the figure.
[music]
Draw a tangent line with a length of
[music] 50 and an angle of 222°.
Trim the drawing.
Draw a straight line starting from point
D with a length of 66 [music] and an
angle of 60°.
Draw a vertical line segment.
Draw a straight line starting from point
O with an X direction offset of 31 and a
Y [music] direction offset of minus 36.
Draw a circle with a radius of four
centered at the end point of the line.
Delete redundant line segments.
>> [music]
>> Snap to the tangent point and draw a
vertical line segment.
Repeat the above operation.
Trim the drawing.
