Description

Technical Field

[0001] This utility model relates to the technical field of turntable bearing processing equipment, and in particular to a turntable bearing production and processing device. Background Technology

[0002] In the production and processing of slewing bearings, the bearing race is a key component, and its production and processing quality significantly affects the overall quality of the bearing. During the processing of the bearing race, it needs to be placed in a bogie-type resistance furnace for high-temperature heat treatment. Currently, in the process of transporting the bearing race on the bogie, simple heat-resistant steel pads or bases are mostly placed on the bogie for vertical support (i.e., the axis of the bearing race is perpendicular to the ground). This method of transport has the following shortcomings in actual operation: 1. The method of using heat-resistant steel pads to support the collar only provides bottom support and cannot effectively limit the outer circle of the collar. During the movement of the trolley, the collar is prone to shaking and friction, which may even lead to tipping over in severe cases, posing a major safety hazard. 2. The method of using a heat-resistant steel base to support the rings is limited by the fixed size of the base, which can only accommodate rings of one diameter. When supporting the rings in a cubic manner, it not only relies entirely on the operator's experience and visual inspection, making it difficult to quickly and accurately center and place them, but also has poor versatility. For multi-variety, small-batch production, the heat-resistant steel base needs to be changed frequently, resulting in low production efficiency and high tooling management costs. 3. When the ring is placed vertically using a heat-resistant steel pad or heat-resistant steel base, the lower end face of the ring will contact the trolley, and the inner ring of the ring will be blocked by the heat-resistant steel base. This not only makes it easy for the ring to not be heated evenly and fully, but also makes it inconvenient for subsequent rapid hoisting and quenching operations. Therefore, there is an urgent need for a turntable bearing manufacturing and processing device that combines versatility, stability, protection, and ease of operation. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model discloses a turntable bearing production and processing device. This utility model not only achieves universal and stable clamping of various sizes of bearing rings through an adjustable radial limiting structure, fundamentally eliminating the risk of tipping during transportation, but also utilizes an open support design to ensure uniform heating during heat treatment and efficient and convenient hoisting during quenching.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A slewing bearing manufacturing and processing apparatus includes a trolley for transporting slewing bearing races after heat treatment. A support component is detachably mounted on the trolley for vertically positioning and limiting the slewing bearing races. The support component includes: The central column is detachably installed on the upper part of the trolley; At least three support rods are evenly distributed around the central column, and the lower surface of the support rods is on the same plane as the lower surface of the central column; The movable rod is located inside the support rod and can be adjusted by extending outward from the end of the support rod. The upper and lower surfaces of the movable rod and the upper and lower surfaces of the support rod are on the same plane. The limiting component has a movable rod at one end away from the central column, which is used to lock and limit the movement of the turntable bearing ring.

[0005] Furthermore, the upper surface of the support rod is provided with a movable groove that is arranged along the axial direction of the support rod and passes through the support rod. The end of the movable groove away from the central column is an open structure. The movable rod is located in the movable groove and can extend outward along its open end.

[0006] Furthermore, the two inner sidewalls of the movable groove are provided with several vertical ridges arranged in an orderly manner along the axial direction of the movable groove, and the two sides of the movable rod are provided with several vertical ridges that correspond one-to-one with the vertical ridges on the inner sidewall of the movable groove, and the lower end is an open structure limiting groove.

[0007] Furthermore, the length of the vertical ridge is less than the depth of the movable groove, and the lower end face of the vertical ridge is in the same plane as the lower surface of the support rod.

[0008] Furthermore, both ends of the movable rod are equipped with lifting holes.

[0009] Furthermore, the limiting component includes a limiting block with an isosceles trapezoidal structure, the inclined surface of which is positioned towards the central column.

[0010] Furthermore, the upper surface of the movable rod is provided with several mounting grooves along the axial direction of the movable rod at one end away from the central column, and the lower end of the limiting block is provided with a mounting rod that is inserted and connected to the mounting groove.

[0011] Furthermore, the upper surface of the trolley is provided with several polygonal positioning slots arranged in a matrix, and the lower surface of the central column is provided with polygonal positioning rods that are compatible with the polygonal positioning slots.

[0012] Furthermore, a lifting ring is provided on the upper surface of the central column.

[0013] Furthermore, the contact surfaces of the support rod, movable rod, and limiting component with the turntable bearing ring are all coated with a flexible ceramic composite coating.

[0014] Compared with the prior art, the beneficial effects of this utility model are: The support system, consisting of a central column, support rod, movable rod, and limiting components, can be quickly adjusted to meet the vertical support requirements of turntable bearing rings of different diameters, greatly reducing the number of tooling and lowering tooling management and storage costs. It is particularly suitable for flexible production of multi-specification products. The ring is suspended and positioned by the support rod, the support rod and the limiting component. Sufficient space is left between its lower end face and the trolley panel, and between the inner hole and the central column, forming an efficient hot air circulation channel. This not only allows the ring to be heated evenly and fully, effectively ensuring the uniformity of the heat treatment structure, but also facilitates the subsequent hoisting operation of the ring. By connecting the support components to the trolley through a hoisting mechanism, the position of the support components on the trolley can be flexibly adjusted and securely locked according to process requirements, ensuring a uniform heat field inside the furnace during batch heat treatment. This invention not only achieves universal and stable clamping of various sizes of rings through an adjustable radial limiting structure, fundamentally eliminating the risk of tipping during transportation, but also utilizes an open support design to ensure uniform heating during heat treatment and efficient and convenient hoisting during quenching.

Detailed Implementation

[0017] The technical solution of this utility model will be described below with reference to the accompanying drawings of the embodiments of this utility model. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this utility model for the convenience of describing this utility model, and do not indicate or imply that the device or element referred to must have a specific orientation.

[0018] Please refer to the instruction manual appendix. Figure 1-5 This utility model provides a technical solution: Example 1: A slewing bearing manufacturing and processing apparatus includes a trolley 1 for transporting slewing bearing rings after heat treatment. The trolley 1 is equipped with a support member 2 for vertically positioning and limiting the slewing bearing rings. Specifically, the support member 2 includes a central column 2.1 located on the upper part of the trolley 1. At least three support rods 2.2 are evenly distributed around the circumference of the central column 2.1 on the outer side of the central column 2.1. The lower surface of the support rods 2.2 is on the same plane as the lower surface of the central column 2.1. The upper surface of the support rods 2.2 is provided with a movable groove 2.2.1 arranged axially along the support rods 2.2. The end of the movable groove 2.2.1 away from the central column 2.1 is open. A movable rod 2.3 is provided inside the movable groove 2.2.1. The movable rod 2.3 can extend outward through the open end of the movable groove 2.2.1, thereby satisfying the support for slewing bearing rings of different diameters. When the support rod 2.2 and the movable rod 2.3 provide vertical support for the turntable bearing ring, in order to ensure the level of the turntable bearing ring, the movable groove 2.2.1 is set through the support rod 2.2. The upper and lower surfaces of the movable rod 2.3 are on the same plane as the upper and lower surfaces of the support rod 2.2. Through the vertical support of the turntable bearing ring by the support rod 2.2 and the movable rod 2.3, most of the turntable bearing ring is in a suspended state, which not only makes its heat treatment more uniform and efficient, but also facilitates the rapid hoisting and quenching of the turntable bearing ring in the subsequent process. To achieve quantitative adjustment of the movable rod 2.3, several vertical ridges 2.2.2 are arranged in an orderly manner along the axial direction of the movable groove 2.2.1 on both inner sidewalls of the movable groove 2.2.1. Several limiting grooves 2.3.1 with open structures at their lower ends are provided on both sides of the movable rod 2.3, which correspond one-to-one with the vertical ridges 2.2.2 on the inner sidewall of the movable groove 2.2.1. By using the insertion and adjustment of the limiting grooves 2.3.1 on both sides of the movable rod 2.3 with the vertical ridges 2.2.2 on the inner sidewall of the movable groove 2.2.1, not only can quantitative extension adjustment of the movable rod 2.3 be achieved, but the friction between the movable rod 2.3 and the movable groove 2.2.1 is also greatly increased, ensuring the horizontal stability of the movable rod 2.3. In order to facilitate the adjustment of the movable rod 2.3, lifting holes 2.3.3 are provided at both ends of the movable rod 2.3. The end of the movable rod 2.3 away from the central column 2.1 is equipped with a limiting component 2.4 for locking and limiting the turntable bearing ring. In order to ensure that the support component 2 can provide stable and efficient support for the turntable bearing ring in the bogie furnace, the support component 2 is made of heat-resistant steel. Its high-temperature strength, creep resistance (the ability to resist slow deformation under stress and high temperature) and oxidation resistance have reached an excellent balance point. The long-term operating temperature can reach 1150°C, which fully meets the requirements of the bogie furnace heat treatment. In order to avoid wear caused by the support component 2 in supporting the turntable bearing ring, the contact surfaces of the support rod 2.2, movable rod 2.3 and limiting component 2.4 with the turntable bearing ring are all equipped with flexible ceramic composite coating. The coating is made of zirconium oxide (ZrO2) ceramic, which has extremely high hardness, excellent wear resistance and extremely low coefficient of friction.

[0019] In Example 2, to prevent wear on the upper end of the vertical ridge 2.2.2, the length of the vertical ridge 2.2.2 is less than the depth of the movable groove 2.2.1, and the lower end face of the vertical ridge 2.2.2 is on the same plane as the lower surface of the support rod 2.2. Correspondingly, the limiting grooves 2.3.1 on both sides of the movable rod 2.3 will not penetrate the upper surface of the movable rod 2.3, thereby keeping the upper surface of the movable rod 2.3 flat and providing strong support for the stable support of the turntable bearing ring.

[0020] In Example 3, to ensure the horizontal stability of the turntable bearing ring, several limiting components 2.4 are needed to form an annular limiting groove that matches the outer diameter of the turntable bearing ring. This results in the turntable bearing ring being difficult to accurately place into the annular limiting groove when it is hoisted onto the support component 2. Furthermore, the limiting components 2.4 will cause wear between themselves and the outer surface of the turntable bearing ring. To achieve accurate and rapid placement of the turntable bearing ring and reduce wear, the limiting component 2.4 includes a limiting block 2.4.1 with an isosceles trapezoidal structure. The inclined surface of the limiting block 2.4.1 faces the central column 2.1. This structure makes the inner diameter of the annular limiting groove formed by several limiting blocks 2.4.1 decrease from top to bottom, which provides strong assistance for the subsequent accurate vertical placement of the turntable bearing ring and effectively reduces the friction between the limiting block 2.4.1 and the outer surface of the turntable bearing ring.

[0021] In Example 4, during the support of turntable bearing rings of different diameters, the movable rod 2.3 is adjusted and limited by the insertion of the vertical ridge 2.2.2 and the limiting groove 2.3.1. This makes it impossible to make precise adjustments to the movable rod 2.3, resulting in the limiting component 2.4 being unable to effectively limit and clamp the turntable bearing rings. To ensure stable clamping of the turntable bearing rings, the upper surface of the movable rod 2.3, away from the central column 2.1, is provided with several mounting grooves 2.3.2 arranged axially along the movable rod 2.3. The lower end of the limiting block 2.4 is provided with a mounting rod 2.4.2 that is inserted and connected to the mounting grooves 2.3.2. Through the extension adjustment of the movable rod 2.3, the short-distance insertion adjustment of the limiting block 2.4, and the inclined surface of the limiting block 2.4, stable clamping and limiting of the turntable bearing rings of different diameters can be achieved when they are placed vertically for limiting.

[0022] In Example 5, to meet the batch heat treatment requirements of trolley 1 for turntable bearing rings of different diameters, the position of support member 2 needs to be adjusted according to the ring diameter. To facilitate the position adjustment of support member 2, the upper surface of trolley 1 is provided with several polygonal positioning grooves 1.1 arranged in a matrix, and the lower surface of the central column 2.1 is provided with polygonal positioning rods 2.1.1 that are compatible with the polygonal positioning grooves 1.1. To facilitate the lifting operation of support member 2 by the staff, the upper surface of the central column 2.1 is provided with lifting rings 2.1.2.
