Embodiment Construction

[0017] Such as figure 1 with figure 2 As shown, the bottom mold in this embodiment includes a bottom plate 1 , and four support points 2 of equal height are connected on the upper side of the bottom plate 1 . Preferably, the above four support points 2 are on the same circumference. In addition, two positioning points 3 on the same circumference are connected on the upper side of the base plate 1 . The circles where the four supporting points 2 are located are concentric with the circles where the two positioning points 3 are located, and the two positioning points 3 are located on the periphery of the four supporting points 2 .

[0018] A first slide pin connection through hole 4 , a second slide pin connection through hole 5 and a threaded through hole 6 are provided on the bottom plate 1 . The first sliding pin 7 and the second sliding pin 8 are slidably connected in the first sliding pin connecting through hole 4 and the second sliding pin connecting through hole 5 res...

Abstract

The invention discloses a fixed-micropyle boring and milling conical surface bottom die. The depth of the processed conical surface is easy to be controlled when the bottom die is adopted for processing fixed-micropyle conical surfaces, and the processing operation is convenient and quick. The bottom die comprises a bottom plate, wherein three or more supporting points with equal heights and two or more positioning points which are positioned on an identical periphery are connected on the upper side surface of the bottom plate; a first sliding pin connecting through hole is arranged on the bottom plate; a first sliding pin is glidingly connected in the first sliding pin connecting through hole; a contact is connected with the top part of the first sliding pin; and an adjusting mechanism used for controlling the first sliding pin to move in the first sliding pin connecting through hole is connected at the lower side of the bottom plate.

Description

technical field [0001] The invention relates to a tool for processing a bead ring, in particular to a bottom mold for boring and milling a bead hole cone on the bead ring. Background technique [0002] A plurality of bead holes are arranged on the bead ring, and a tapered surface is arranged on the edge of each bead hole. The cone surface of the bead hole is the main working surface of the bead ring. It requires high precision. The depth of the cone surface is usually required to be controlled within the range of 0.1mm, and the depth consistency of the cone surface is required to be controlled within the range of 0.05mm. Because the control of the depth of the taper surface of the fixed bead hole is equivalent to the control of the depth of the blind hole, its processing is more difficult. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a bottom mold for boring and milling the cone surface of the fixed bead hole...
