Description

Technical Field

[0001] The utility model relates to the technical field of screw processing, in particular to multi-station screw processing equipment. Background Art

[0002] Screws are tools that use the physical and mathematical principles of the circular rotation of the inclined surface of an object and the friction force to gradually tighten objects and parts. The surface of the screw is provided with threads, and a screw processing device is required to open a thread groove on the screw rod. Patent search found that the publication number: CN116277824A discloses an automatic screw processing device. Through a lubrication box, a lubrication tube and a connecting hose, the lubricating oil is transported from the connecting hose to the lubrication tube through an extraction pump, and the lubricating oil enters the groove tube. As the lubricating oil continues to increase, the groove tube moves, which will drive the magnetic sliding block to move together. Because the lubricating oil contains an indefinite amount of oil residue, and because of the gravity of the oil residue itself, the oil residue will fall into the groove tube and the inner wall of the tube cavity. When the oil residue is too much, it will cause blockage to the oil seepage hole. During the movement of the groove tube, the rubber tube at the bottom of the groove tube will clean the inner wall of the tube cavity, clean up the oil residue blocking the surface of the oil seepage hole, improve the lubrication quality, thereby improving the service life and accuracy of the positioning pin, and also improve the mold clamping accuracy, and improve the quality of subsequent screw production.

[0003] When existing screw processing equipment is used to open external threads on a screw rod, it is necessary to switch between multiple cutter heads to process the screw rod in order to form external threads, chamfers, and side plane angles on the screw rod. Switching of cutter heads wastes a lot of time, resulting in a slow processing speed for the screws. In order to solve the above problems, a multi-station screw processing equipment is proposed in the present application. Utility Model Content
