Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
Referring to fig. 1-4, a special tool for processing a box cover includes a main tool bar 1, the main tool bar 1 is rectangular, the left side of the main tool bar 1 is fixed on a cutter head 5, a groove penetrating through the main tool bar 1 is formed in the right side of the main tool bar 1, where it should be noted that the groove may be a square groove, a circular groove or a trapezoidal groove, and a square groove is adopted in this embodiment.
The square groove notch orientation is perpendicular with main cutter arbor 1's central line, vice cutter arbor 2 is installed to square inslot transition fit, just vice cutter arbor 2 with 1 installation angle of main cutter arbor is 90 degrees, be provided with two screw holes in the square groove, and the direction of screw hole is perpendicular with the opening direction in square groove, and passes main cutter arbor 1 sets up, the screw hole is fixed with vice cutter arbor 2 through internally mounted's interior hexagonal jackscrew 4, interior hexagonal jackscrew 4 is M4.
The tool bit 3 is arranged at the lower end part of the auxiliary tool bar 2, the tool bit 3 is made of tungsten-tantalum alloy, the whole tool bit 3 is square or rectangular, and is welded on the auxiliary tool bar 2 by heating and melting copper welding rods and borax, the tool bit 3 is a vulnerable part, after long-term use, the tool bit 3 is worn, size deviation occurs, and the tool bit 3 needs to be replaced or ground; after replacement or grinding, the workpiece is clamped again for use.
As shown in fig. 4, it should be noted that the overall appearance of the box cover 6 to be processed according to the present invention is conical, and the middle part is provided with a round hole 7, when the case cover 6 is processed, the front side of the case cover 6 is vertical to the axial direction of the main cutter bar 1, further, a plurality of round steps to be processed are arranged inside the front side of the case cover 6 along the periphery of the central axis of the case cover 6, the top part of the back side of the case cover 6 is a surface to be processed, the surface to be processed is round, and is concentric with a round hole 7 at the center of the box cover 6, the length of the auxiliary cutter bar 2 is less than the diameter of the round hole 7, and is larger than the difference between the diameter of the circle of the surface to be processed on the reverse side of the box cover 6 and the diameter of the round hole 7, the design has the advantages that the length of the auxiliary cutter bar 2 is smaller than the diameter of the round hole 7, the auxiliary cutter bar 2 can be ensured to pass through the round hole 7 of the box cover 6 to realize the processing of the reverse surface to be processed of the box cover 6.
