Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of heat treatment, and particularly relates to a heat treatment equipment for gear machining. BACKGROUND

[0002] Gear machining quenching is a crucial strengthening process in the gear manufacturing process. By precisely heating the gear tooth part or the whole and then rapidly cooling it, the metal internal metallographic structure is changed, thereby significantly improving the surface hardness, wear resistance and fatigue strength of the gear, and guaranteeing the service life and transmission stability of the gear under high load operation. The induction heat treatment equipment is the core device for realizing this process. It generates eddy current self-heating of the gear in the alternating magnetic field by means of electromagnetic induction principle, can precisely control the heating area and temperature, and can perform local quenching on the key parts such as the gear tooth surface and the gear root, and has the advantages of fast heating speed, high heat efficiency and small workpiece deformation.

[0003] At present, the gear heat treatment equipment is difficult to realize continuous closed-loop processing of the workpiece. The links such as feeding, quenching, transferring after quenching, cooling and discharging after cooling rely on manual operation or need to be matched with multiple devices, which not only increases the labor and equipment costs, but also leads to low efficiency due to the time-consuming connection between links. At the same time, although some multi-station quenching devices at the present stage attempt to operate continuously, the workpiece rotation control has defects. In order to ensure uniform heating of the workpiece in the induction coil, an independent rotating mechanism needs to be provided for each station, which needs to be driven by a separate component and a complex synchronous control assembly, resulting in a bulky device structure, increased occupation area, and also increased manufacturing cost and maintenance difficulty. When multiple sets of mechanisms operate, they are prone to out-of-sync due to component wear, signal delay and other factors, affecting the stability of the workpiece rotation and leading to quenching quality deviation.

The discharging plate 51 penetrates through the side wall of the water tank 11 and receives the workpiece falling from the guide frame 5 and the guide plate 22, and conveys the workpiece out of the equipment, realizing automatic discharging of the workpiece and completing the entire machining cycle.

[0028] It should be noted that the working principle of the gear machining heat treatment equipment is as follows: after the equipment is started, the servo motor 9 in the equipment bin 1 starts to operate first, the output end thereof is connected with the reduction box 91 through the shaft coupling, the reduction box 91 is adjusted in speed, the vertical rod 25 fixedly connected with the reduction box 91 is driven to rotate, the vertical rod 25 penetrates through the water tank 11 and is fixed at the top with the tray 2, so that the tray 2 rotates synchronously with the vertical rod 25. The conveying rod 4 arranged in array on the tray 2 also rotates, the movable rod 41 in the conveying rod 4 is tightly attached to the surface of the support seat 3 at the bottom under the action of gravity, along with the rotation of the tray 2, the universal ball 42 slides along the track formed by the normal part 31, the protruding part 32 and the recessed part 33 of the support seat 3, and then the movable rod 41 slides in the sleeve 23 of the tray 2, so as to realize the lifting action of the movable rod 41.

[0029] When the movable rod 41 rotates with the tray 2 to the protruding part 32 below the induction coil 7, the universal ball 42 moves upward along the protruding part 32 because the height of the protruding part 32 is higher than that of the normal part 31, the movable rod 41 slides upward, the embedded column 44 at the upper end of the movable rod 41 gradually lifts the workpiece at the top, until the workpiece preliminarily enters the inside of the induction coil 7; at the same time, the gear sleeve 43 fixedly sleeved on the movable rod 41 rises with the movable rod 41, gradually engages with the driving gear 10 at the upper end of the vertical rod 101, the vertical rod 101 penetrates through the water tank 11 and is fixed at the lower end with the output end of the servo motor 102 in the equipment bin 1, at this time, the servo motor 102 operates, drives the vertical rod 101 and the driving gear 10 to rotate, the driving gear 10 drives the gear sleeve 43 and the movable rod 41 to rotate, so that the workpiece rotates at a constant speed in the induction coil 7, ensuring that each part of the workpiece can uniformly receive induction heating, improving the uniformity of quenching and heating.
