Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing housing technology, and in particular to a processing device for bearing housing. Background Technology
[0002] Slewing bearing housings are large and extra-large bearing housings with special construction that can withstand comprehensive loads. They are characterized by their compact structure, sensitive rotation, and convenient installation and maintenance. Where there is a bearing, there must be a support point. The internal support point of the bearing is the shaft, and the external support is what is commonly referred to as the bearing housing. Currently, the cooling method for traditional bearing housing machining mostly adopts a single cutting fluid pouring method.
[0003] A bearing housing processing device, with publication number CN214322757U, includes a base and a fixed frame on the base. The fixed frame has a vertically oriented cylinder. A drive motor is installed at the bottom output end of the cylinder. An adjustment mechanism is installed at the bottom of the drive motor. Two sets of grinding rods are connected to the bottom of the adjustment mechanism. The adjustment mechanism drives the grinding rods to move towards or away from each other. A bearing body is fixed on the base. The adjustment mechanism includes a fixed plate, a fixed groove, a rotating motor, a two-way lead screw, a fixed seat, a slide rail, and a mobile power supply. The bearing housing processing device provided by this utility model adjusts the two sets of grinding rods to move closer or further apart by setting the adjustment mechanism, thus facilitating the grinding of bearing housings with different inner wall sizes. It is very convenient to use, highly automated, and easy to promote and use.
[0004] Regarding the aforementioned technologies, the existing bearing housing machining devices have the following drawbacks: the heat generated by the friction between the tool and the workpiece can cause the local temperature of the workpiece to rise. Especially during high-speed cutting, thermal expansion may cause the critical dimensions of the bearing housing, such as the bore diameter and shoulder, to deviate from the design requirements, affecting the roundness and surface roughness of the bearing housing bore system. Therefore, this utility model provides a bearing housing machining device. Utility Model Content

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.
[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0025] Example 1: Reference Figure 1-4The illustrated bearing housing processing apparatus includes a processing table 1, which supports the bearing housing part to be processed and serves as the basic support platform for the entire apparatus. The processing table 1 has a clamping shell 10 inside, made of aluminum alloy. Aluminum alloy has good thermal conductivity, enabling rapid heat transfer. The clamping shell 10 positions and clamps the bearing housing part, ensuring its stability and preventing displacement during processing. Simultaneously, it works with a cooling assembly to cool the part, reducing the impact of heat generated during processing on the part's precision. A cooling assembly is installed on the side wall of the processing table 1, including a circulating cooling pump 4 fixedly connected to the side wall of the processing table 1. The circulating cooling pump 4 provides low-temperature cooling to the cooling system. The output end of the circulating cooling pump 4 is fixedly connected to an inlet pipe 19, which is used to transport the coolant cooled by the circulating cooling pump 4 to the clamping shell 10. One end of the inlet pipe 19 is fixedly connected to and communicates with the side wall of the clamping shell 10. A return pipe 20 is fixedly connected to the side wall of the clamping shell 10, which is used to return the coolant after absorbing heat to the circulating cooling pump 4. One end of the return pipe 20 is fixedly connected to the input end of the circulating cooling pump 4. The inlet pipe 19 and the return pipe 20 form a coolant circulation channel to realize the circulation of coolant. A partition 23 is fixedly connected inside the clamping shell 10. The partition 23 can divide the internal space of the clamping shell 10 to form two interconnected swimming lanes. The flow path of the coolant within the clamping shell 10 is optimized to improve the cooling effect. An elastic steel plate 22, made of copper alloy, is installed on the inner wall of the clamping shell 10. Copper alloy has excellent thermal conductivity, and the elastic steel plate 22 provides a certain degree of elastic cushioning when clamping parts, preventing damage to the part surface. It also more efficiently transfers the heat generated during part processing to the coolant. An enhanced heat dissipation assembly is installed on the outer side of the machining table 1. This assembly includes a flow guide ring pipe 15 located on the outer side of the machining table 1. Vegetable oil and coolant are introduced into the flow guide ring pipe 15, which distributes the coolant to various atomizing nozzles 18. Multiple atomizing nozzles 18 are located at the bottom of the flow guide ring pipe 15. The nozzle 18 atomizes the coolant and sprays it onto the processing area to cool and lubricate the cutting tools and parts. At the same time, the impact force of the atomized coolant washes away the debris generated during processing. A support frame 3 is fixedly connected to the side wall of the processing table 1. The support frame 3 supports the threaded rod 8 and ensures that the threaded rod 8 rotates stably. The threaded rod 8 is rotatably connected inside the support frame 3. The threaded rod 8 drives the moving parts that cooperate with it to move by rotating, thereby achieving the clamping or loosening action of the parts. A first motor 5 is fixedly connected to the side wall of the support frame 3. The first motor 5 provides power for the rotation of the threaded rod 8. By precisely controlling the speed and direction of the first motor 5, the clamping force and clamping position of the parts can be precisely controlled.
[0026] Example 2: Reference Figure 1-4Based on the same concept as Embodiment 1 above, this embodiment further proposes that the output end of the first motor 5 passes through the support frame 3, and the output end of the first motor 5 is fixedly connected to one end of the threaded rod 8. The first motor 5 serves as a power source, transmitting torque through the output shaft to drive the threaded rod 8 to rotate, providing power for the clamping action of the part and ensuring that the threaded rod 8 obtains stable and continuous rotational power. A guide rod 9 is fixedly connected inside the support frame 3. The guide rod 9 is used to guide the movement of the moving block 11, ensuring that the moving block 11 will not rotate or deviate when moving along the axial direction of the threaded rod 8, thus ensuring the movement accuracy. The moving block 11 is threadedly connected to the side wall of the threaded rod 8. The moving block 11 and the threaded rod 8 are connected through threaded transmission to convert the rotational motion of the threaded rod 8 into linear motion. Linear motion enables precise control of the position of the moving block 11. The moving block 11 slides on the side wall of the guide rod 9. By sliding on the guide rod 9, the moving block 11 can move smoothly in a fixed direction, reducing friction and resistance during movement, while improving the straightness and positioning accuracy of the movement. An electric push rod 7 is fixedly connected to the side wall of the moving block 11. The electric push rod 7 can precisely control the extension and retraction length according to the processing requirements, and is used to adjust the distance between the milling cutter 17 and the workpiece, realizing the feed and retraction actions of the milling cutter 17, ensuring the accuracy of the machining depth. A connecting plate 13 is fixedly connected to the output end of the electric push rod 7. The connecting plate 13 is used to connect the electric push rod 7 and the second motor 16, playing a role in stable support and power transmission, ensuring the connection between the second motor 16 and the milling cutter 17. During processing, the machine remains stable and does not shake. A second motor 16 is fixedly connected to the bottom of the connecting plate 13. The second motor 16 provides rotational power to the milling cutter 17. By adjusting the speed of the second motor 16, the cutting speed of the milling cutter 17 can be controlled to adapt to different processing requirements. The output end of the second motor 16 is fixedly connected to the milling cutter 17, which is the component that directly cuts the bearing seat part. Through high-speed rotation, the part is milled to complete machining processes such as planes, grooves, and holes, achieving part forming and precision machining. An air pump 12 is fixedly connected to the side wall of the moving block 11. The air pump 12 is used to generate high-pressure gas to provide power for the spraying of coolant, enabling the coolant to be delivered through the vent pipe 14 to the guide ring pipe 15 and from the atomizing nozzle 18. The output end of the air pump 12 is fixedly connected to a vent pipe 14, which is used to transmit the high-pressure gas generated by the air pump 12 to transport the coolant from the guide ring pipe 15 to the atomizing nozzle 18, realizing the directional delivery of the coolant. One end of the vent pipe 14 is fixedly connected to and communicates with the side wall of the guide ring pipe 15, so that the high-pressure gas and coolant are mixed in the guide ring pipe 15 and distributed to each atomizing nozzle 18. The bottom of the processing table 1 is fixedly connected to a support leg 2, which is used to support the entire processing table 1, ensuring that the processing device remains stable during processing and preventing the processing accuracy from decreasing due to vibration or external force. The processing table 1 is equipped with a processing plate 24, which is a platform that directly supports the processing of parts and provides a stable working surface for the processing of parts.The processing plate 24 has multiple chip collection grooves 21 inside. These grooves collect chips generated during processing, allowing them to fall into the guide frame 6. This centralized collection and discharge of chips prevents accumulation that could affect processing quality and equipment operation. The bottom of the processing table 1 is fixedly connected to the guide frame 6, which guides the chips and coolant in the chip collection grooves 21 to flow smoothly out of the processing table 1 and into the designated collection area, ensuring the cleanliness of the processing area and the continuity of processing.
[0027] The working principle of this device is as follows: When using this device, the part to be processed is first placed between a pair of clamping shells 10 and fixed. The first motor 5 rotates the threaded rod 8, causing the moving block 11 to move along the guide rod 9. The electric push rod 7 is extended and the second motor 16 is rotated. The part is processed using the milling cutter 17. At the same time as processing, the air pump 12 is started. The mixture of coolant and vegetable oil that has been placed in the guide ring pipe 15 is sprayed onto the part being processed through the atomizing nozzle 18 through the air pipe 14. The circulating cooling pump 4 is started simultaneously, and the cooled water is introduced into the clamping shell 10 through the inlet pipe 19 and circulated back through the return pipe 20 for cooling. The sprayed coolant and the chips generated during processing are discharged from under the processing table 1 through the chip chute 21 and the guide frame 6.
[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
