In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are used merely for convenience of description and for simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention. Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.
Referring to fig. 1 to 4, the technical object of the present invention is achieved by a rack for heat treatment of gear blanks, comprising a base 1, wherein a threaded rod 2 and a fixed rod 3 are fixedly arranged on the upper surface of the base 1, a plurality of nuts 4 are connected to the outer portion of the threaded rod 2 by a thread, a metal sleeve 5 is arranged above each nut 4, the metal sleeve 5 is rotatably sleeved on the outer portion of the threaded rod 2, the diameter of the metal sleeve 5 is smaller than that of the nut 4, a plurality of embedded grooves 6 with side end openings are arranged in the fixed rod 3 along the height direction of the fixed rod 3, the number of the embedded grooves 6 is larger than that of the metal sleeve 5, a rotating rod 7 is fixedly connected to the side wall of each metal sleeve 5 by welding, a plurality of grooves 8 with upper end openings are arranged in the rotating rod 7 along the length direction, the one end that the metal sleeve 5 was kept away from to dwang 7 is pegged graft inside of inlay groove 6 and with dead lever 3 fixed connection, here the inside that the metal sleeve 5 one end was kept away from to dwang 7 has seted up first screw hole 9, and the second screw hole 10 that feeds through inlay groove 6 is seted up to the lateral wall of dead lever 3, through inserting the screw in first screw hole 9 and the second screw hole 10 with dwang 7 and dead lever 3 fixed connection.
The working principle of the utility model is as follows: with gear blank (inside offer usually the through-hole) through dwang 7 keep away from the one end of metal sleeve 5 cup joint in recess 8 of dwang 7, rotate metal sleeve 5 and make dwang 7 rotate in step, when dwang 7 butt is at the lateral wall of dead lever 3, adjust nut 4's position height for dwang 7 inserts the inside of inlaying inslot 6, and through inserting the screw of first screw hole 9 and second screw hole 10 with dwang 7 and dead lever 3 fixed connection. Because the number of the embedded grooves 6 is more than that of the metal sleeves 5, when the diameter of the gear blank to be hoisted is larger, one group of sleeves, the nuts 4 and the rotating rods 7 can be moved to increase the distance between two adjacent rotating rods 7, sufficient space is reserved for hoisting the gear blank, the quality of heat treatment is ensured, when the diameter of the gear blank to be hoisted is smaller, one group of sleeves, the nuts 4 and the rotating rods 7 can be added to ensure that the number of the gear blank to be hoisted is larger, and the times of heat treatment are reduced, therefore, the rack for heat treatment of the gear blank avoids the surface of the gear blank from being directly contacted with the rack by sleeving the gear blank in the groove 8 of the rotating rod 7, ensures that the inside of the gear blank is uniformly heated during heat treatment, ensures the quality of the processed gear, in addition, the utility model can hoist the gear blanks with different diameter specifications, the applicability is wide, and the method is suitable for large-scale production.
