Technical Field

[0001] This utility model relates to the field of bearing sleeve heat treatment technology, specifically a heat treatment device for processing deep groove ball bearing sleeves. Background Technology

[0002] Bearing rings are ring-shaped parts of radial rolling bearings with one or more raceways. During the processing of bearing rings, heat treatment is required to give the processed bearing rings strong toughness and strength.

[0003] The utility model patent with announcement number CN214735972U discloses a high-efficiency heat treatment box for bearings, which relates to the field of heat treatment technology. It includes a support device, a protective device, an auxiliary device, a transmission device, and a guiding device. The support device includes a support block, a support rod, a support column, and a support plate. The protective device includes a fixing ring, a fixing column, a receiving plate, and a heating box. The auxiliary device includes an auxiliary heater, a temperature sensor, a motor, a rotating shaft, and a controller. The transmission device includes a hydraulic tank, a slide rail, a slider, a transverse rod, and a telescopic gripper. The guiding device includes a sealing cover, a guiding plate, a guiding channel, and a placement frame.

[0004] However, there are still some shortcomings in the above technical solution: the above technical solution uses a telescopic gripper to move the placement frame to remove the heated workpiece, but in this way, the removed placement frame is likely to affect the subsequent placement of workpieces, and cannot achieve a convenient continuous feeding effect. Utility Model Content

[0005] The purpose of this utility model is to provide a heat treatment device for processing deep groove ball bearing sleeves, so as to solve the problem in the prior art mentioned in the background that the removed placement frame easily affects the subsequent placement of workpieces and cannot achieve a convenient continuous feeding effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat treatment apparatus for machining deep groove ball bearing sleeves, comprising a heat treatment chamber.

[0007] The heat treatment chamber has openings on both sides, and a horizontally sliding placement frame is provided inside the heat treatment chamber. A sliding plate is connected to the side wall of the heat treatment chamber, and the placement frame is placed on the sliding plate.

[0008] The top of the sliding plate is provided with a guide groove, and a lead screw is rotatably installed in the guide groove. A push plate is slidably installed in the guide groove, and a lead screw nut is installed in the push plate. The lead screw nut is threadedly connected to the lead screw. A motor is installed on the side wall of the sliding plate, and the output shaft of the motor is connected to the lead screw.

[0009] By adopting the above technical solution, during use, the workpiece is placed in the placement frame, and the rotation of the lead screw driven by the motor drives the push plate to move laterally, thereby pushing the placement frame into the heat treatment chamber for heat treatment. After heat treatment, the push plate is used again to push the subsequent placement frame into the heat treatment chamber, pushing out the previous placement frame, thus realizing a continuous loading and unloading process.

[0010] As a further embodiment of this utility model: a lifting plate is installed above the heat treatment box, and a hydraulic cylinder with its output shaft facing downward is installed on the top of the lifting plate. The output shaft of the hydraulic cylinder is connected to the top of the heat treatment box. Vertical baffles are installed on both sides of the lifting plate, and the bottom of the baffles is inserted into the opening.

[0011] By adopting the above technical solution, during use, the extension and retraction of the hydraulic cylinder drives the lifting plate to rise and fall on the top of the heat treatment box, thereby driving the baffle to rise and fall, and controlling the opening and closing of the openings on both sides of the heat treatment box.

[0012] As a further embodiment of this utility model: the bottom of the placement frame is evenly provided with a plurality of openings, and sliders are installed on both the front and rear walls of the placement frame.

[0013] By adopting the above technical solution, the heat inside the heat treatment chamber can pass through the placement frame through the opening design during use, and the slider design facilitates the lateral movement of the placement frame.

[0014] As a further embodiment of this utility model: the heat treatment chamber has sliding grooves on both the front and rear walls, and the height of the sliding grooves matches the height of the slider.

[0015] By adopting the above technical solution, when the placement frame enters the heat treatment chamber, the slider will be inserted into the groove, which not only provides a guiding effect but also prevents the placement frame from tilting.

[0016] As a further embodiment of this utility model: an inclined guide plate is installed on the side wall of the heat treatment box away from the sliding plate, and the guide plate is aligned with the bottom of the opening.

[0017] By adopting the above technical solution, the guide plate design guides the ejected placement frame during use, facilitating subsequent processing.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the heat treatment device for machining deep groove ball bearing sleeves,

[0019] The system is equipped with a placement frame, a sliding plate, a lead screw, a push plate, and a motor. The motor drives the lead screw to rotate, which in turn drives the push plate to move laterally. As the push plate moves laterally, it pushes the placement frame into the heat treatment chamber and pushes out the placement frame that has already been treated in the heat treatment chamber. At the same time as loading, the previous placement frame is pushed out, which makes unloading convenient.

[0020] In addition, the heat treatment device for processing deep groove ball bearing sleeves is also equipped with a baffle, a lifting plate and a hydraulic cylinder. Before unloading and loading, the extension of the hydraulic cylinder causes the lifting plate to lift the baffle, thereby opening the opening to facilitate the entry and exit of the placement frame.
