Push frame drilling fixture design 5, fork into a group of drilling machine fixture assembly manufac

Summary. 1. Meet the stability and reliability of workpiece positioning in the process of use2. There is enough bearing or clamping strength to ensure the processing process of the workpiece on the tooling fixture;3. Meet the simple and fast operation in the clamping process;4. The wearing parts must be a structure that can be quickly replaced, and it is best not to use other tools when the conditions are sufficient5. Meet the reliability of repeated positioning of the fixture in the process of adjustment or replacement;6. Avoid complex structure and expensive cost as much as possible7. Use standard parts as components as much as possible8. Form the systematization and standardization of the company's internal products.

Evaluate the assembly manufacturability of the jig of the fork group drilling machine.

Through the design of the fork processing process, it can be found that the design of a product needs a good cooperation of each processing process to be functional and evaluated.

The drawings are not clear.

1, take the surface of the common edge line of 90 and 36 dimensions as the reference, the blank hole of the auxiliary elastic pin rough 22 as the reference, clamp the 12 sides of the cross bar, and rough boring 36 holes.

2.Position the face of 36 holes and both sides of the hole and the face of the C3 chamfer, coarse and fine boring 22 holes, drill 6mm small holes, wash the small end face of 16 to the size of 30, wash the end face of 90 size, wash the end face of 32 size, and rough and fine boring 14 (the hole with precision requirements).

3.With 22 holes and the end face, 14 (the hole with precision requirements) and the end face positioning, 16 small end face auxiliary support compression, fine boring 36 holes, wash both end faces to the size.

When designing the fixture, pay attention to the main datum of the axis of the two holes and the symmetry of the left and right parts of the part.

This picture will be drawn for at least two weeks or so, and I don't know if anyone will give it to you.

(Structural type and main size of drill casing, drill plate)

If it is a drill oblique hole, it needs to be attached to the design of the process hole after the fourth step) Fifth, the fixture ** with drawing.

Positioning dimensions and tolerances between components can be stated).
