Description

Technical Field

[0001] The utility model relates to the technical field of spark plug production equipment, in particular to a spark plug automatic iron shell assembly device. Background Art

[0002] The spark plug is an important component of the gasoline engine ignition system. It can introduce high voltage electricity into the combustion chamber and make it jump over the electrode gap to generate sparks, thereby igniting the combustible mixture in the cylinder. It is mainly composed of a wire nut, an insulator, a wire screw, a center electrode, a side electrode and a shell. The side electrode is welded to the shell.

[0003] Reference Publication (Announcement) No.: CN218677976U discloses a spark plug automatic iron shell assembly device. The utility model can place the spark plug in the slot block by setting a slot block and a second telescopic column structure, and then push the spark plug directly into the iron shell through the second telescopic column. This process not only greatly reduces the damage to the hands of workers, but also improves the production efficiency of spark plugs. By setting a first telescopic column and a push block structure, the assembled spark plug can be pushed out of the bottom of the storage box, so that it is convenient for workers to take out the spark plug. However, in the actual installation process, the limit of the iron shell is not accurate enough. When pushing the spark plug into the iron shell, the pressure applied easily causes the iron shell to shake, resulting in reduced accuracy during docking and increased scrap rate. In view of this, the present application proposes a spark plug automatic iron shell assembly device. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3 A spark plug automatic iron shell assembly device comprises a base 1, a plurality of fixing bolts 2 are arranged on the upper surface of the base 1, a body 3 is installed on the upper end of the base 1, a collection box 5 is arranged inside the body 3, a handle 4 is fixedly installed on the side wall of the collection box 5, a horizontal bar 19 is fixedly connected to the upper surface of the body 3, a groove 20 is opened on the top of the body 3, and the position of the groove 20 corresponds to the collection box 5. It should be noted that in the process of continuous feeding, the assembled spark plug will be pushed over the horizontal bar 19 and fall from the opened groove 20 into the collection box 5 below.

[0021] A drive box 6 is installed at the upper end of the body 3, and a guide plate 7 is connected to the upper end of the body 3. A partition is arranged in the middle of the guide plate 7. The guide plate 7 is arranged at an angle, and one end of the guide plate 7 close to the body 3 passes through the side wall of the drive box 6 and extends to the inside of the drive box 6.

[0022] An electric push rod 8 is fixedly installed inside the drive box 6, and a movable plate 9 is connected to the telescopic end of the electric push rod 8, and a plurality of anti-slip protrusions are provided on the side wall of the movable plate 9. A pad 10 is fixedly connected to the bottom of the drive box 6, and the pad 10 is arranged below the movable plate 9 and contacts with the bottom of the movable plate 9. Furthermore, due to the different diameters of the spark plug and the iron shell, by providing the pad 10 with corresponding heights, it can be ensured that the axis of the spark plug and the iron shell are located on the same horizontal line, thereby improving the accuracy of the access point.

[0023] The telescopic end of the electric push rod 8 is connected to a driving device through a connecting rod 11. The driving device includes a first rack 12, a gear 13 and a second rack 14. The gear 13 is meshed with the first rack 12 and the second rack 14 at the same time. One end of the first rack 12 is fixedly connected to the connecting rod 11, and the other end of the first rack 12 extends to the outside of the driving box 6. The gear 13 is rotatably connected to the inner wall of the driving box 6. A limiting device is provided at the lower end of the second rack 14, and the upper end of the second rack 14 extends to the outside of the driving box 6.
