[0001] The utility model relates to the technical field of polishing equipment, in particular to a polishing equipment for a central electrode of a spark plug. 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. When processing the spark plug, polishing equipment is needed to polish the center electrode of the spark plug to ensure that the surface accuracy of the spark plug center electrode meets the specifications required for subsequent installation operations.

[0003] Polishing equipment is needed when processing spark plugs, among which the "A polishing mechanism for spark plugs" disclosed in the publication number "CN218874903U" has solved the various drawbacks of existing spark plugs that there is no special equipment on the side electrodes to pre-polish the side electrodes of the spark plugs.

[0004] However, there are still many defects in the actual use of polishing equipment with similar structure. For example, in the prior art, the device needs to use external auxiliary equipment to perform multiple grinding and polishing operations on the center electrode of the spark plug, so as to ensure the polishing accuracy requirement of the center electrode of the spark plug, which reduces the quality of polishing of the center electrode of the spark plug by the device. At the same time, when using the device, the device is easily restricted by the specifications of the spark plug, which reduces the practical effect of the device and is not convenient for the device to be promoted and used. Therefore, it is necessary to design a polishing device for the center electrode of the spark plug. Utility Model Content

[0008] The interference mechanism comprises an installation box, in which an interference spring is fixedly installed.

[0009] Preferably, two groups of docking seats are fixedly installed on the outer side of the carrier, and bolt members are threadedly installed inside the docking seats.

[0010] Preferably, a support rod extending into the interior of the shell is fixedly installed at one end of the resistance spring, and one end of the support rod is fixedly connected to one side of the grinding disc. A locking piece is movably installed on one side of the installation box through an installation groove, and one end of the locking piece extends into the interior of the installation box.

[0011] Preferably, a protection box is fixedly installed on the outside of the uniform speed motor, and the top of the protection box is fixedly connected to the top of the turntable.

[0012] Preferably, a bolt seat is fixedly mounted on the top of the carrier close to the driving mechanism, and the top of the bolt seat is fixedly connected to the bottom of the mounting seat.

[0014] Beneficial Effects

[0015] The utility model provides a polishing device for the center electrode of a spark plug. Compared with the prior art, it has the following beneficial effects:

[0016] 1. The servo motor is powered on to drive the turntable to rotate. The rotating turntable can drive the uniform speed motor to rotate to the specified position, and then the electric rod is powered on to drive the linkage frame to move the vertical position. The linkage frame that moves the vertical position can drive the servo motor to move the synchronous position. The servo motor that moves the synchronous position can drive the turntable to move the vertical position to the specified position, so that the shell moves to the outside of the spark plug center electrode, and then the uniform speed motor is powered on to drive the shell to rotate. The rotating shell can drive the grinding disk to rotate through the resistance mechanism. The rotating grinding disk can polish the spark plug center electrode. The function of improving the polishing quality of the spark plug center electrode can be achieved by adjusting the use position of grinding disks of different specifications. The center electrode of the spark plug is polished in sequence by orderly using grinding disks of different precisions, thereby improving the polishing quality of the spark plug center electrode.

[0017] 2. The downwardly moved shell can drive the installation box to move synchronously, so that the grinding disc can move against the outside of the central electrode of the spark plug. The moving grinding disc can compress the resistance spring through the support rod, so that the resistance spring undergoes elastic deformation. When the grinding disc moves to the specified position, the high elastic force of the resistance spring can drive the support rod to move horizontally. The moving support rod can drive the grinding disc to perform resistance polishing operation on the central electrode of the spark plug, thereby improving the compatibility of the device, avoiding the device being restricted by the specifications of the spark plug, increasing the practical effect of the device, and facilitating the popularization and use of the device.
