The application discloses a large internal ratchet wheel machining method, which comprises the following steps: S1, rotating a machine tool B shaft; S2, tooling a ball cutter (4) installed on the machine tool B shaft accessory with any two points on a large tooth surface of a tooling slot and any one point on a small tooth surface respectively to obtain coordinate values of each tooling point in a cutter tip coordinate system; S3, according to the intersection of a tooth root virtual circle under the cutter tip coordinate system and the connecting line of the two tooling points on the large tooth surface, the intersection point constitutes the coordinate values of a tooth root vertex in the cutter tip coordinate system, and the coordinate values of the tooth root vertex in the cutter tip coordinate system and the offset of the cutter tip coordinate system relative to a part coordinate system are obtained according to a trigonometric function relationship; and S4, the offset is used for compensating the cutter tip position deviation generated by the rotation of the machine tool B shaft. The technical effect of the application is that qualified large internal ratchet wheels are machined by compensating the cutter tip position deviation and the part tooth slot phase deviation, qualified large internal ratchet wheels are machined on a machine tool by using a common ball cutter, and production cost is saved.

The invention relates to a machining method of a duplicate gear, which comprises the following steps of: roughly machining a duplicate gear part, reserving allowance on a tooth surface, and selecting a large-end marking tooth and a small-end marking tooth; then carrying out heat treatment; if the included angle between the tooth groove center line of the large-end marking tooth and the tooth groove center line of the small-end marking tooth is large due to rough machining errors and heat treatment deformation, it cannot be guaranteed that the final included angle between the tooth groove center lines of the large end and the small end is qualified through borrowing machining; if yes, a distribution diagram of the small end tooth groove center line and the large end tooth groove center line and reference lines on the two sides of the small end tooth groove center line are made, and the small end tooth groove center line can be determined as long as the included angle between at least one large end tooth groove center line and the most adjacent reference line is small and the borrowing machining qualification condition is met. If yes, the large-end marking teeth and the small-end marking teeth can be reset for finish machining, and it is guaranteed that the part is qualified; compared with the prior art, the angle out-of-tolerance rate of the center line of the marked tooth groove can be reduced, and therefore the rate of unqualified products is reduced.

The utility model discloses an embedded part tooth profile bush processing device, including split type's upper die holder (1) and lower die holder (2), and the middle part detachable connection of lower die holder (2) has first fixed mould core (3) and second fixed mould core (4), and first fixed mould core (3) and second fixed mould core (4) between present top and bottom distribution and mutually adhere to, and the one side of first fixed mould core (3) or second fixed mould core (4) forms first air groove (5), and the outside of first air groove (5) is equipped with the air room (6) of being located first fixed mould core (3) or second fixed mould core (4) installation gap place, and the outside of air room (6) is equipped with the second air groove (7) of being located first fixed mould core (3) one side side wall, and first air groove (5), air room (6) and second air groove (7) between sequentially communicate. The utility model can realize the timely discharge to the air in forming cavity.

The utility model discloses a wear-resistant part tooth groove lining plate for a crusher, which belongs to the technical field of crushing equipment and comprises a groove plate, penetrating openings are formed in the periphery of the groove plate, telescopic rods are arranged at the four corners of the bottom of the groove plate, buffer springs are sleeved on the telescopic rods, a bottom plate is fixedly connected to the bottom of each telescopic rod, and the bottom of each telescopic rod is fixedly connected with a base plate. A transverse buffering assembly is arranged on the bottom plate, an opening and closing assembly is arranged in the groove plate, and a lining plate is nested outside the groove plate. According to the utility model, by arranging the transverse buffer component and the spring, the direct impact on the lining plate is buffered to a great extent, and the wear resistance of the lining plate can be improved, so that the service life of the crusher is prolonged, the product quality is improved, and the production cost is reduced. In addition, the lining plate can be effectively and rapidly installed, fixed and replaced through the opening and closing assembly, operation is easy and convenient, time and labor are saved, and the replacement efficiency of the lining plate and the operation progress of the crusher are greatly improved.

The clip applier comprises a clip head assembly and a clip applier body assembly, the near end of the clip head assembly is connected with the far end of the clip applier body assembly, the clip head assembly comprises a clip head and an outer tube, the outer tube is connected to a ligation clip in a sleeved mode, the clip applier body assembly comprises a trigger assembly, a sliding assembly and a ratchet component, and the trigger assembly comprises a trigger body and an elastic component; the trigger main body is pulled towards the near-end direction to drive the elastic component to jump in the ratchet component, so that the sliding component slides towards the far-end direction, and the ligation clip is controlled to be closed; the trigger body is pushed in the far end direction, the elastic component is driven to jump in the ratchet component, the sliding part slides in the near end direction, and therefore the ligature clip is controlled to be opened.

The invention discloses a method for protecting and improving the fatigue resistance of an alloy gear by beewax. The method comprises the following steps: S1, coating beewax; s2, copper plating; s3, nitriding is conducted, specifically, the tooth part is subjected to nitriding treatment, after nitriding is completed, the tooth part is coated with beewax again, 3-5 layers of beewax are evenly smeared, and the whole tooth part is completely covered with the beewax; and S4, copper removal is conducted, specifically, the gear body is subjected to copper removal treatment. The beeswax is used for protecting the tooth portion of the part, the nitriding layer obtained after nitriding is reserved, the anti-fatigue life of the gear can be remarkably prolonged through protection of the beeswax on the fading layer, and the alloy gear is low in cost, convenient to operate, free of pollution and residues and free of damage.
