Abstract
The utility model relates to a bearing raceway quenching device which comprises a stand, and has the innovation points that the stand is provided with a vertical rotating shaft; the top of the rotating shaft is fixedly provided with a fixture body which is provided with an ejector rob used for supporting a bearing; the ejector rob has a screw rod structure which is matched with the fixture body by thread in a sliding way; the rotating shaft is driven by a belt and is connected with a motor; the two sides of the lower end of the rotating shaft are provided with vertical cylinders; cylinder bodies of the vertical cylinders are fixedly connected with the stand; and piston rods of the vertical cylinders are connected and fixed with the rotating shaft by connecting plates. When the bearing raceway quenching device is in use, the rotating shaft is driven to sink into water by the cylinders for quenching, and the rotating shaft and the fixture body are driven to rotate by the motor, so that quenching is ensured to be carried out evenly; and two mechanisms respectively run, so that the service life of the bearing raceway quenching device is long, and the normal production is guaranteed.
Description
Technical field
The utility model relates to a kind of raceway quenching device, particularly a kind of raceway quenching device of long service life.
Background technology
The fork truck bearing in process of production; Need quench to raceway; The raceway quenching device comprises clamp body, and clamp body is provided with the push rod that can hold up bearing, and the below of clamp body is provided with a pair of rod hydraulic ram; The top of this pair rod hydraulic ram is connected with clamp body, and the lower end is connected with motor through belt transmission.When quenching, carry out induction quenching, and drive the clamp body rotation through belt transmission, guarantee uniform quenching by motor through the bearing submerged water-cooled that two rod hydraulic rams drive on the clamp body.The shortcoming of this kind structure is: because two rod hydraulic ram when moving axially, also has electric motor driving to rotate, the hydraulic ram sealing member is easy to wear, and work-ing life is low, needs often to safeguard, influence is produced normally.
Summary of the invention
The technical problem that the utility model will solve provides a kind of raceway quenching device of long service life.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of raceway quenching device; Comprise frame, its innovative point is: said frame is provided with a vertical turning axle, and the top of turning axle is fixed with clamp body; This clamp body is provided with the push rod of pedestal bearing, and this push rod is the screw-rod structure of joining with clamp body screw thread cunning; Turning axle is connected with motor through belt transmission; The both sides, lower end of turning axle are provided with vertical oil cylinder, and the cylinder body of this oil cylinder is fixedly connected with frame, and the piston rod of oil cylinder is connected fixing with turning axle through web plate.
Further, the center of said turning axle is a hollow structure, and it is built-in with water-cooled tube; The center, top of clamp body is provided with cooling spray; This cooling spray center is provided with cavity, evenly is provided with the spiracle that is communicated with cavity on the periphery, and the cavity of cooling spray is communicated with water-cooled tube.
The advantage of the utility model is: during use, sink down in the water by the hydraulic oil cylinder driving turning axle and to quench, rotate by electric motor driving turning axle and clamp body, guarantee to quench evenly, two mechanisms move respectively, long service life guarantees to produce normally.
The cooling spray that is communicated with water-cooled tube is set on the clamp body, and cooling spray cools off bearing inner race during quenching, guarantees quenching efficiency.
