Detailed Description
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following description will explain the specific embodiments of the present invention with reference to the accompanying drawings. It is evident that the drawings in the following description are only examples of the invention, from which other drawings and other embodiments can be obtained by a person skilled in the art without inventive effort.
As shown in fig. 1-7, a method for removing a pole cap and milling a pole by one-time centering is implemented, and a new pole 6 is designed for an original pole 5 based on the required pole size according to the formula:
a is more than or equal to a+k, wherein a is the radius of the original pole, k is the fit clearance between the original pole and the original pole cap, and A is the design radius of the new pole;
b is more than or equal to A+ck, wherein B is the radius of the new pole cap, and c is a coefficient with a value of 0.8;
when the new pole cap is sleeved on the new pole, the radial maximum offset of the new pole cap is k, the new pole cap is screwed off at a pole cap screwing station on a production line, and then the new pole cap enters a pole milling station to mill poles, so that the original pole can be obtained after milling.
In the assembly line operation process, the method only needs to center the milling pole station with the pole cap as a reference in an initial state, continuous pole milling operation can be carried out after the pole cap is determined, the post after milling is kept in a required size, no waste products are generated, and the production efficiency is high. The secondary centering does not need to be performed due to the offset of the axis of the new pole and the axis of the new pole cap in the radial direction.
The eccentric fit clearance k between the pole and the pole cap is normally selected to be 0.3-0.8mm, preferably 0.5. Too small a gap can cause poor phenomena such as blocked fit, battery closing and seam removal, and too large a gap can cause poorer concentricity.
The fit clearance between the inner diameter r of the terminal and the post after milling is normally selected to be 0.3-0.8mm, preferably 0.5. Too small a gap can lead to difficulty in releasing the terminal of the automatic line, and too large a gap can lead to lead leakage of the hole when the terminal is welded.
Taking the terminal inside diameter r5.5mm as an example, i.e., post milling a=5mm (original post).
The dimension A of the new pole is more than or equal to 5.5mm, preferably 5.6mm.
B is more than or equal to 0.8x0.5+5.5, and 5.9/6/6.1mm can be selected.
The middle cover comprises a cover body 1 and a pole cap 2 which is integrally formed with the cover body, the opening of the pole cap is downward, and the opening end of the pole cap is in a horn mouth shape.
The pole cap extends upwards from the bottom 4 of the terminal groove 3 on the middle cover, and the milling cutter mills to the level of the bottom of the terminal groove when milling the pole.
a+1.25k≥A≥a+k。
It should be noted that the above embodiments can be freely combined as needed. The foregoing is merely a preferred embodiment of the present invention and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present invention, which are intended to be comprehended within the scope of the present invention.
