Description
Technical field
The present invention relates to a kind of equipment of pre-sealed process that alkaline battery is closed up, particularly relate to and a kind ofly head into mechanism for the close up negative electrode of pre-sealed process of alkaline battery.
Background technology
In the production process of cylindrical alkaline battery, by negative electrode, battery is sealed after positive and negative pole material is filled in the inside of alkaline cell anode box hat, then volume pressure, shaping are carried out to battery, leak to prevent internal material, the quality of sealing directly decides security performance and the discharge performance of battery, and therefore the encapsulation process of battery is one critical process in alkaline battery manufacture process.
Encapsulation process many employings integral type of current cylindrical alkaline battery is elongated head into bar absorption negative electrode after, negative electrode is pushed in battery and carry out pre-sealed process of closing up, in the fabrication process, owing to being subject to raw material, the impact of the uncertain factors such as equipment, especially at overall dimension battery less than normal as LR61, in the manufacture process of the size battery such as LR03, negative electrode to head in process easily and box hat inwall produces light touch, be integral type elongate rod owing to heading into bar, thus easily occur bending and deformation, thus cause negative electrode insertion position not just, and then have a strong impact on the security performance of battery.
Summary of the invention
Technical problem to be solved by this invention is to provide after one is touched in the course of the work can carry out position adjustment voluntarily, thus avoids heading into that bar occurs bending and deformation heads into mechanism for the close up negative electrode of pre-sealed process of alkaline battery.
The present invention solves the problems of the technologies described above adopted technical scheme:
A kind ofly head into mechanism for the close up negative electrode of pre-sealed process of alkaline battery, comprise termination seat and head into bar, a cylindrical cavity is provided with in described termination seat, the described rearward end heading into bar has been wholely set a termination, the sidepiece of described termination is outer convex globoidal, described termination is arranged in described cylindrical cavity, the outer convex globoidal of described termination and the inwall tight fit of described cylindrical cavity, a spring is provided with between the bottom of described termination and described cylindrical cavity, the front end face of described termination seat is fixedly installed a cover plate, described cover plate is provided with a through hole, described heads into bar through described through hole, the described diameter heading into bar is less than the diameter of described through hole, the front end face of described termination is withstood on the rear end face of described cover plate by the tension force of described spring.
The diameter of the center cross-sectional of described termination is greater than the diameter of described termination front end face, and the diameter of the center cross-sectional of described termination is greater than the diameter of described termination rear end face, and the front end face diameter of described termination is identical with rear end face diameter.
Be provided with a spring base in described cylindrical cavity, the rear end face of described termination be provided with a groove, one end of described spring is arranged in described spring base, and the other end of described spring is arranged in described groove.
Described cover plate and described termination seat are bolted to connection.
Described through hole is arranged on the center of cover plate.
Compared with prior art, the invention has the advantages that: the rearward end heading into bar is wholely set the termination that a sidepiece is outer convex globoidal, utilize the cooperation on cambered surface and the face of cylinder simultaneously in conjunction with spring action, when there is light touch, cambered surface can produce the rotation offset of certain angle in the face of cylinder, thus drive and head into bar and adjust position voluntarily, effectively overcome and head into bar and produce diastrophic problem, ensure that the concentricity heading into bar entirety, and then the performance of battery in effective guarantee production process, extend the useful life heading into bar simultaneously.

Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail:
As shown in Figure 1, a kind ofly head into mechanism for the close up negative electrode of pre-sealed process of alkaline battery, comprise termination seat 1 and head into bar 2, a cylindrical cavity 11 is provided with in termination seat 1, the rearward end heading into bar 2 has been wholely set a termination 21, the sidepiece of termination 21 is outer convex globoidal, termination 21 is arranged in cylindrical cavity 11, the outer convex globoidal of termination 21 and the inwall tight fit of cylindrical cavity 11, a spring 4 is provided with between the bottom of termination 21 and cylindrical cavity 11, the front end face of termination seat 1 is fixedly installed a cover plate 3, cover plate 3 is provided with a through hole 31, head into bar 2 through through hole 31, the diameter heading into bar 2 is less than the diameter of through hole 31, the front end face of termination 21 is withstood on the rear end face of cover plate 4 by the tension force of spring 4.
In this particular embodiment, the diameter L of the center cross-sectional of termination 21 is greater than the diameter L2 of termination front end face, and the diameter L of the center cross-sectional of termination is greater than the diameter L1 of termination rear end face, and the front end face diameter L2 of termination is identical with rear end face diameter L1, as shown in Figure 3.
In this particular embodiment, be provided with a spring base 12 in cylindrical cavity 11, the rear end face of termination 2 be provided with a groove 22, one end of spring 4 is arranged in spring base 12, and the other end of spring 4 is arranged in groove 22.
