Description

Technical Field

[0001] This utility model relates to the field of slewing bearing production technology, specifically a quenching equipment for producing slewing bearings. Background Technology

[0002] Slewing bearings are a new type of mechanical component, consisting of an inner ring, an outer ring, and rolling elements. Slewing bearings can withstand large axial and radial loads and overturning moments. The rolling elements can be spherical or cylindrical. When manufacturing slewing bearing components, the rolling elements need to be quenched to improve their fatigue strength and reduce their toughness, thereby increasing the service life of the rolling elements and the entire slewing bearing.

[0003] A search revealed a Chinese patent document disclosing a quenching device for producing slewing bearings [Application No.: CN202321328369.6]. This quenching device for producing slewing bearings includes a housing, a support plate, a hanging plate, and a coil assembly. The front of the housing is open at the top, forming an operating opening. A first electric push rod is installed on the bottom surface of the housing, and the support plate is installed at the front end of the first electric push rod. A second electric push rod is installed on the top surface of the housing, and the hanging plate is installed at the front end of the second electric push rod. The coil assembly is installed below the hanging plate and is composed of several coils connected in series. Several collars are installed on the support plate, and the number and position of the coils and collars are consistent.

[0004] The device disclosed in this patent can limit the slewing bearing by means of a collar, so as to make its position more accurate during the quenching process. However, when quenching slewing bearings of different sizes, the diameter of the collar cannot be changed, which makes the device less effective in limiting some slewing bearings. Furthermore, moving the slewing bearing during the quenching process can easily cause its position to shift, thereby reducing the applicability of the device. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5As shown, a quenching device for producing slewing bearings includes a mounting shell 1. The interior of the mounting shell 1 is used to store quenching fluid. A heating mechanism 2 is installed on the top of the mounting shell 1. The heating mechanism 2 can heat the slewing bearing by electric heating, thereby facilitating subsequent quenching. An electric telescopic rod 3 is bolted to the inner cavity of the mounting shell 1. A receiving plate 4 is bolted to the top of the electric telescopic rod 3. The receiving plate 4 is used to support the slewing bearing. A fixing groove 5 is opened on the top of the receiving plate 4. A connecting groove 6 is opened in the inner cavity of the fixing groove 5. Under the action of the connecting groove 6, several fixing grooves 5 can be connected, thereby facilitating the subsequent movement of parts inside the fixing grooves 5. A pushing mechanism 7 is installed on one side of the receiving plate 4. Movable blocks 8 are slidably connected to both sides of the inner cavity. A locking rod 9 is fixedly connected to the top of each movable block 8. The movable blocks 8 cooperate with the pushing mechanism 7. Under this action, when it is necessary to fix the slewing bearing, the movable blocks 8 can be moved by the pushing mechanism 7, thereby changing the distance between the two locking rods 9. This allows the locking rods 9 to open the interior of the slewing bearing, achieving the effect of fixing it. This effectively improves the stability of the slewing bearing during the quenching process and prevents positional displacement of the slewing bearing during quenching, which would affect the quenching effect of the equipment. The fixing groove 5 has a T-shaped cross-section design, and its inner wall is slidably connected to the surfaces of the movable blocks 8 and the locking rods 9. Under this action, the movable block 8 can be prevented from moving out of the fixed groove 5 by the shape, effectively improving the stability of the movable block 8 and preventing it from easily moving out of the fixed groove 5 and affecting the limiting of the slewing bearing by the locking rod 9. Guide grooves 11 are provided on both sides of the inner cavity of the fixed groove 5. Guide blocks 12 are slidably connected to the inner cavity of the guide grooves 11. One side of the guide block 12 is fixedly connected to the surface of the movable block 8. Under this action, the movable block 8 can only be offset by the cooperation of the guide grooves 11 and the guide blocks 12, so that the position of the pushing mechanism 7 can be more accurate when it moves when it squeezes the movable block 8. A tension spring 10 is fixedly connected to one side of the locking rod 9. The other end of the extension spring 10 is fixedly connected to the surface of the locking rod 9 on the other side. Under this action, when the pushing mechanism 7 no longer squeezes the movable block 8, the two locking rods 9 can drive the movable block 8 back to its original position through the cooperation of the extension spring 10, which makes it convenient for the operator to remove the slewing bearing and effectively improves the applicability of the equipment. Water outlet holes 15 are opened on both sides of the bottom of the inner cavity of the fixing groove 5. The water outlet holes 15 are used in conjunction with the fixing groove 5 and the connecting groove 6. Under this action, when the quenching liquid inside the mounting shell 1 enters the interior of the fixing groove 5 and the connecting groove 6 through the fixing groove 5, the quenching liquid inside can be discharged under the action of the water outlet holes 15, thereby reducing the quenching liquid inside the fixing groove 5 and the connecting groove 6.

[0026] The pushing mechanism 7 includes a fixed plate 71 disposed on one side of the receiving plate 4. A connecting plate 72 is fixedly connected to one side of the fixed plate 71. The other end of the connecting plate 72 extends into the interior of the connecting groove 6 and is slidably connected to the inner wall of its penetration point. Pushing blocks 73 are fixedly connected to both sides of the surface of the connecting plate 72. Both the pushing block 73 and the movable block 8 have an inclined structure design on one side. The pushing block 73 works in conjunction with the movable block 8. Under this action, the fixed plate 71 can be pushed to cause the connecting plate 72 to move the pushing block 73, thereby allowing the pushing block 73 to push the movable block 8 to move, thus fixing the locking rod 9 to the slewing bearing. Moreover, with the coordination of the number of connecting plates 72 and pushing blocks 73, all locking rods 9 can be moved, making it more convenient to fix the slewing bearing and effectively improving the efficiency of fixing the slewing bearing. A locking groove 13 is opened on one side of the inner cavity of the connecting groove 6. A locking block 14 is fixedly connected to the bottom of plate 2. The inner wall of the locking groove 13 is slidably connected to the surface of the locking block 14. Under this action, the connecting plate 72 can be limited by the locking groove 13 and the locking block 14, so that the connecting plate 72 is more stable when moving. This avoids the connection effect between the pushing block 73 and the movable block 8 due to the instability of the connecting plate 72 when moving. A threaded rod 16 is rotatably connected to one side of the receiving plate 4. The other end of the threaded rod 16 passes through to the other side of the fixed plate 71 and is threadedly connected to the inner wall of its penetration. Under this action, it is more convenient to adjust the position of the fixed plate 71 when needed. Moreover, with the cooperation of the threaded rod 16, the fixed plate 71 will not easily shift its position after moving, effectively improving the stability of the fixed plate 71 during use and avoiding the connection between the pushing block 73 and the movable block 8 due to the instability of the fixed plate 71.

[0027] It is worth noting that the technical features proposed in this technical solution, such as the mounting shell 1, heating mechanism 2, electric telescopic rod 3, and receiving plate 4, should be regarded as the technologies in the comparative case. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0028] Working principle: First, the slewing bearing to be quenched is placed on the surface of the locking rod 9. After the slewing bearing is in place, the operator rotates the threaded rod 16 to move the fixed plate 71. When the fixed plate 71 moves, it drives the pushing block 73 through the connecting plate 72 to press against the movable block 8. This causes the movable block 8 to move the locking rod 9, so that the locking rod 9 moves and contacts the inner wall of the slewing bearing. This prevents the slewing bearing from easily shifting its position, which is not only convenient but also avoids problems during subsequent quenching. In cases where the slewing bearing moves easily and affects the quenching effect, the operator then heats the slewing bearing using the heating mechanism 2. After heating, the electric telescopic rod 3 drives the receiving plate 4 and the slewing bearing on its surface to move into the quenching liquid inside the mounting shell 1 to quench the slewing bearing. After quenching, the receiving plate 4 returns to its original position. Then, the fixed plate 71 releases the pressure of the pushing block 73 on the moving block 8, and the tension spring 10 allows the locking rod 9 to return to its original position, thereby releasing the limitation on the slewing bearing.
