Technical Field
The invention relates to a clamp for machining holes and notches of parts such as an outer cover and a machining method of the outer cover.
Background
The processing of holes and gaps of parts such as control box outer covers is basically realized by a method of installing and positioning on a processing center for processing. Due to the fact that the outer cover of different products has large difference in size, required clamps are different and cannot be used universally when machining is conducted through a machining center. Each outer cover needs to be manufactured with one or more clamps, which causes the problems of various clamps, more clamps, long processing period and the like. Because the outer cover type parts belong to parts with thin walls and large overall dimensions, the surfaces of the parts are easily scratched due to improper clamp design, and the appearance quality is influenced.

Detailed Description
The invention is described in further detail below with reference to:
as shown in fig. 1, a fixture for processing holes and gaps of parts such as an outer cover comprises a base 1, an outer cover inner mold 2, an outer cover outer contour positioning ring 3 and a pressing plate 4; the base 1 is fixed with an outer cover inner type mould 2 through bolts; the outer contour 2 of the outer cover is positioned on the base 1, and the inner ring of the outer contour positioning ring 3 of the outer cover is embedded with the outer edge of the inner mould 2 of the outer cover; the pressing plate 4, the outer contour positioning ring 3 of the outer cover and the base 1 are respectively provided with corresponding bolt holes; the outer contour positioning ring 3 of the outer cover is fixed on the base 1 by the bolts A5 and B6 passing through the corresponding bolt holes.
When the clamp is assembled, the base 1 is fixed with the inner cover type tire 2 through the bolts, the outer sides of the periphery of the inner cover type tire 2 are placed behind the inner contour of the outer cover 7 of the control box, the outer cover outer contour positioning ring 3 clamps the outer contour of the outer cover 7 of the control box, the pressing plate 4 is placed on the processing surface of the nameplate hole, the bolt A5 and the bolt B6 penetrate through the screw hole formed in the outer cover outer contour positioning ring 3 and then the screw hole formed in the base 1, the outer cover outer contour positioning ring 3 and the outer cover 7 of the control box under the pressing plate 4 are fixed on the base 1, and therefore the outer cover 7 of the control box can be more firmly fixed on the base 1.
The base 1 functions as: connecting the fixture with the accessory of the machine tool to fix the whole fixture; installing an outer cover inner mold 2 and an outer cover outer contour positioning ring 3; the pressure plate 4 is locked to the control box outer cover 7 through a bolt A5 and a bolt B6.
The outer cover inner type tire 2 and the outer cover outer contour positioning ring 3 are combined to position the control box outer cover 7, so that the control box outer cover 7 cannot move in the X-axis direction, the Y-axis direction and the Z-axis direction.
The outer cover inner type tire 2, the outer cover outer contour positioning ring 3 and the pressing plate 4 lock the control box outer cover 7 on the clamp.
A method for processing holes and notches of parts such as outer covers comprises the following steps:
