Embodiment Construction

[0033] Such as Figure 4 and Figure 5 As shown, the present invention includes a mold handle 1, a pressure head 2, a base 3, a slider 4, a guide column 5, a spring 6, a special-shaped pin 7, a positioning pin 8, a limit block 9, a linear bearing 10, and a hard limit 11 And backing plate 16. Wherein, the die handle 1 is fixed on the upper die of the press-fitting equipment, and the die handle 1 is provided with a counterbore for connecting the pressure head 2 . Such as Figure 9 As shown, the threaded hole at the thick end of the pressure head 2 cooperates with the bolt to connect the die handle 1, and the space at the thin end of the pressure head 2 is used to allow the B+ screw rod 15 to pass through during pressing. The base 3 is fixed on the lower mold of the press-fitting equipment through gaskets,

[0034] Such as Figure 4 and Figure 10 As shown, the upper end surface of the base 3 is provided with a groove 301 for placing the head of the B+ screw 15, so the size...

Abstract

The invention discloses a rectifier B and screw rod pressing clamp. The rectifier B and screw rod pressing clamp comprises a mold handle connected to an upper mold of a pressing device, a substrate connected to a lower mold of the pressing device, a pressing head arranged on the mold handle and used for pressing downwards a B and screw rod, guiding columns symmetrically arranged on the substrate,and a slider formed at an avoiding position of the substrate and connected with the guiding columns in a sliding manner; and the substrate is provided with a groove matched with the head of the B andscrew rod. The rectifier B and screw rod pressing clamp has the beneficial effects that compared with a traditional pressing clamp, the mold changing time is saved, and the production efficiency is improved; the situation that an electrode plate tips over in the pressing process is avoided, and therefore the pressing precision is guaranteed; and the situation that because of deformation of the pressing head, the installing precision does not reach the standard is reduced.

Description

technical field [0001] The invention relates to a tooling for a B+ screw rod of a rectifier in an automobile generator, in particular to a clamp for pressing a B+ screw rod of a rectifier. Background technique [0002] The B+ screw of the rectifier is the necessary part for the output of the current generated by the car generator to the electrical appliances on the car, so the B+ screw always passes a relatively large current in the working state. There are straight lines at the bottom of the B+ screw, and the diameter of the straight lines is 0.2-0.4mm larger than the screw hole of the plate. Therefore, the B+ screw needs to be pressed into the plate during installation. The press-fit requirements of the B+ screw and the plate are particularly high. If the B+ screw and the plate are deflected during press-fitting, the plate is deformed or cannot be tightly fitted due to other factors, a large contact resistance will be generated between the two. , When the generator is in ...
