Problems solved by technology
[0005] In order to solve the technical problems existing in the background technology, the present invention proposes a four-edged cutter for grinding the welding electrode cap. The contact surface is ground to the designed surface shape, which overcomes the technical problem of vibration caused by the uneven force caused by the contact of the cutting edge in the prior art, improves the surface quality of the electrode cap after the mold is repaired, and the waste after grinding Chips are discharged through the notch for chip removal, and the chip breaking can be achieved by only rotating the cutter core for 1 / 4 turn. The volume of waste chips is 1 / 4 of the existing technology, which overcomes the technical problem of chip removal blockage

The invention relates to the field of electrode cap grinding, in particular to a four-blade cutter for welding electrode cap grinding. The four-blade cutter comprises a welding gun, a static arm, a movable arm, electrode caps, cutter cores and a grinding machine; the static arm and the movable arm are symmetrically mounted on the welding gun, the electrode caps are fixedly mounted on the opposite faces of the static arm and the movable arm, the cutter cores are embedded between the electrode caps, the grinding machine is mounted outside the cutter cores, and the cutter cores and the connecting positions of the cutter cores and the electrode caps are of concave structures; the contact surfaces of the electrode caps and the cutter cores are ground until the designed surface shape is obtained, the technical problem of vibration caused by uneven stress caused by cutting edge contact in the prior art is solved, the surface quality of the electrode caps after grinding is improved, and waste chippings obtained after grinding are discharged out through a chipping discharging notch; and since the cutting edge a and the cutting edge b are coincident in opening direction and are arranged vertically and horizontally, chipping breaking can be achieved by rotating the cutter cores by only 1 / 4 circle, the waste chipping size is 1 / 4 of that in the prior art, and the technical problem about chipping discharging blockage is solved.
Description
technical field [0001] The invention relates to the field of electrode cap grinding, in particular to a four-edged cutter for welding electrode cap grinding. Background technique [0002] The electrode cap is a kind of welding electrode, which is used for welding of resistance welding equipment, such as fixed spot welding machine, hanging spot welding machine and manipulator spot welding machine, etc., because it is set on the electrode connecting rod, so it is called electrode cap. The material is mostly chrome-zirconium copper, and there is also dispersed copper. After a certain number of welding (generally 1000-1200 points), it needs to be ground or replaced due to wear and tear. It belongs to welding consumable parts. The electrode cap grinding tool is caused by uneven force. Vibration causes the grinding surface of the electrode cap to be rough, and the volume of grinding waste generated is relatively large, resulting in poor chip removal and blockage. [0003] In orde...
