Description

Technical Field

[0001] This invention relates to the field of CNC machining equipment technology, and in particular to a machining center for bearing housing production. Background Technology

[0002] As a key basic component supporting bearings in mechanical transmission systems, the machining quality of bearing housings directly affects the operational accuracy and service life of the entire equipment. Currently, bearing housings are widely produced using CNC machining centers, but several efficiency and precision bottlenecks still exist in the process that urgently need to be addressed.

[0003] Traditional machining centers generally employ a single-station design, requiring sequential loading / unloading and machining processes. Each time a workpiece is changed, the machine spindle must stop and wait, resulting in high idle rates. In the workpiece clamping stage, most existing fixtures use a single center positioning or lateral clamping method. For complex bearing housings, this method struggles to maintain high positioning rigidity and stability during machining, especially under multi-directional cutting forces. Even minor displacements or vibrations can directly lead to dimensional deviations, particularly affecting critical geometric tolerances such as the roundness, cylindricity, and perpendicularity of bearing mounting holes to end faces. Furthermore, chips and coolant generated during machining easily remain on the fixture positioning surfaces and workpiece mounting bases. If not thoroughly cleaned before loading / unloading, these residues can cause positioning deviations in subsequent workpieces, creating "false positioning" and potentially leading to batch quality incidents. Currently, cleaning is mostly done manually, which is inefficient, cannot guarantee cleanliness, and increases the labor intensity and safety hazards for operators.

[0004] Therefore, there is an urgent need in this field for a new type of machining center that can achieve efficient continuous machining, has high rigidity and adaptive clamping capability, and can integrate automated cleaning functions, so as to comprehensively improve the quality, efficiency and automation level of bearing housing production. Summary of the Invention

[0023] Preferably, it also includes four air guide grooves, which are respectively located at the top of the four positioning clamps;

[0024] The jet nozzles are provided in four sets and are respectively located in four air guide grooves.

[0031] The technical effects and advantages of this invention are as follows:

[0032] 1. This invention achieves simultaneous processing and loading / unloading of bearing seats by using two bearing seat support plates for switching, maximizing the processing efficiency of bearing seats. By setting a positioning shaft on the upper surface of the bearing seat support plate and cooperating with the positioning clamp, the center and edge of the bearing seat are positioned synchronously to ensure the positioning accuracy of the bearing seat. Furthermore, the bearing seat is initially positioned after placement and automatically corrects and locks itself after being moved to the processing station, reducing the positioning difficulty when placing the bearing seat, simplifying the loading / unloading operation of the bearing seat, and effectively improving the processing efficiency of the bearing seat.

[0033] 2. This invention employs a two-stage positioning structure that first positions and then clamps. During the placement of the bearing housing, the positioning shaft enables rapid positioning of the bearing housing center. Furthermore, during the bearing housing placement process, the positioning clamp is at a low position, which allows for approximate positioning of the bearing housing edge, thereby reducing the precision requirements of the bearing housing during placement. After the bearing housing is placed and switched to the processing station, the positioning clamp is pushed upward to correct and adjust the bearing housing. Then, the limiting clamp inside the positioning clamp is pushed outward to completely fix the bearing housing. The two-stage clamping method effectively reduces the positioning difficulty of the bearing housing, thereby improving the processing efficiency of the bearing housing.

[0034] 3. This invention uses a combination of multiple air-blowing structures to clean residual cutting fluid and machining debris from the surface of the bearing housing support plate. The air nozzle at the top of the positioning clamp, the air guide groove, and the annular groove on the positioning shaft form a set of directional airflow cleaning paths to clean the surface of the bearing housing support plate and the outer wall of the positioning shaft. The cleaning nozzles on both sides of the partition cover form another set of directional airflow cleaning paths for secondary cleaning of the bearing housing support plate surface. The combination of the two airflow cleaning methods ensures the absolute cleanliness of the bearing housing support plate surface before each bearing housing clamping, thereby preventing debris or cutting fluid from affecting the positioning accuracy of the bearing housing and thus ensuring the machining accuracy of the bearing housing.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] like Figures 1 to 13 As shown, the machining center for bearing housing production provided by the present invention is essentially a bearing housing production machining center that enables rapid loading and unloading of bearing housings and air-blowing cleaning of the bearing housing support parts. By employing two bearing housing support plates 4 for switching, the machining and loading / unloading of bearing housings are performed simultaneously, maximizing the machining efficiency of the bearing housings. The positioning shaft 41 on the upper surface of the bearing housing support plate 4, in cooperation with the positioning clamp 431, achieves synchronous positioning of the center and edge of the bearing housing, ensuring the positioning accuracy of the bearing housing. Furthermore, after the bearing housing is initially positioned after placement, it automatically corrects and locks itself after moving to the machining station, reducing the positioning difficulty during bearing housing placement, simplifying the loading and unloading operations of the bearing housings, and improving the machining efficiency of the bearing housings. Efficiency is effectively improved by using a combination of multiple air-blowing structures to clean the residual cutting fluid and machining debris on the surface of the bearing housing support plate 4. The air nozzle 4312 at the top of the positioning clamp 431, the air guide groove 4311, and the annular groove 411 on the positioning shaft 41 form a set of directional airflow cleaning paths to clean the surface of the bearing housing support plate 4 and the outer wall of the positioning shaft 41. The cleaning nozzles 23 on both sides of the partition cover 22 form another set of directional airflow cleaning paths to achieve secondary cleaning of the surface of the bearing housing support plate 4. The combination of the two sets of airflow cleaning methods ensures that the surface of the bearing housing support plate 4 is absolutely clean before each bearing housing clamping, thereby avoiding the impact of debris or cutting fluid on the positioning accuracy of the bearing housing, and thus ensuring the machining accuracy of the bearing housing.

[0060] The positioning shaft 41 is fixedly installed in the middle of the upper surface of the bearing seat support plate 4. The positioning shaft 41 is used to realize the center positioning of the bearing seat.

[0061] The positioning slide groove 43 is provided in four places and is provided on the upper surface of the bearing seat support plate 4.

[0066] The lifting cylinder 321 is located between the slide table 3 and the support plate 32.

[0071] Two fixing plates 33 are provided and fixedly mounted on the top of the support base 31, and the two fixing plates 33 are respectively located on both sides of the support plate 32;

[0072] The slot 422 is located at the bottom of the connecting seat 42 and has a "T" shaped cross section. The slot 422 and the fixing plate 33 are used to limit the bearing seat support plate 4 above the support seat 31.

[0073] Four air guide grooves 4311 are provided and are respectively located at the top of four positioning clamps 431;

[0074] The jet nozzle 4312 is provided in four sets and is respectively located in four air guide grooves 4311. When the positioning clamp 431 is in the lowered state before and after the bearing seat is placed, the four sets of jet nozzles 4312 spray compressed air that is flush with the upper surface of the bearing seat support plate 4 to clean the surface of the bearing seat support plate 4.

[0075] An annular groove 411 is located at the bottom of the outer side wall of the positioning shaft 41 and is flush with the upper surface of the bearing seat support plate 4. The top of the inner side wall of the annular groove 411 is set with an inclined structure. The compressed air ejected by the jet nozzle 4312 flows along the surface of the bearing seat support plate 4 into the annular groove 411 and is then guided to the outer side wall of the positioning shaft 41 to clean the outer side wall of the positioning shaft 41.

[0076] When using a machining center for bearing housing production according to this embodiment, two sets of bearing housing support plates 4 are connected to two mounting brackets 21 on both sides of the support plate bracket 2 by connecting seat 42. When loading the bearing housing, the support plate bracket 2 drives the mounting brackets 21 to rotate, rotating one set of bearing housing support plates 4 to the outside of the machine frame 1. At this time, the bearing housing can be placed on top of the bearing housing support plate 4, and the center hole of the bearing housing is aligned with the positioning shaft 41 on the upper surface of the bearing housing support plate 4. During this process, the bearing housing is placed and initially positioned. During this process, the positioning clamp 431 is at the lowest point, and only a small part of the top of the positioning clamp 431 is located on the upper surface of the bearing housing support plate 4.

[0077] After the bearing housing is initially placed, the support plate bracket 2 drives the mounting frame 21 to rotate, and the mounting frame 21 drives the bearing housing support plate 4 to rotate, so that the bearing housing support plate 4 drives the bearing housing to rotate above the slide table 3. During the rotation, the bearing housing support plate 4 drives the connecting seat 42 to rotate, so that the groove 422 at the bottom of the connecting seat 42 rotates above the fixing plate 33. At this time, the groove 422 and the fixing plate 33 achieve initial positioning between the connecting seat 42 and the support seat 31. Then, the lifting cylinder 321 drives the support plate 32 to move upward, and the support plate 32 presses the top block 46 upward, so that the top block 46 moves upward. The top block 46 moves vertically upward along the guide rod 461, and then the top block 46 presses the annular seat 45, so that the annular seat 45 moves upward. The annular seat 45 first presses the transmission seat 44 through the secondary spring 452, so that the transmission seat 44 moves upward. The transmission seat 44 is connected to the slide rail 441 and The slide block 442 drives the positioning clamp 431 to move upward. At this time, the positioning clamp 431 slides upward. During this process, the positioning clamp 431 presses the side of the bearing seat through the outer rounded corner to make the offset side of the bearing seat return to the correct position. When the transmission seat 44 moves upward to fit against the lower surface of the bearing seat support plate 4, the transmission seat 44 stops moving. At this time, the top block 46 continues to drive the ring seat 45 to move upward. At this time, the ring seat 45 presses the limiting top block 4512 upward through the pressure block 451, so that the limiting top block 4512 slides upward at the vertical part at the bottom of the limiting groove 4511. During the upward sliding process of the limiting top block 4512, it presses the limiting clamp 4513, so that the limiting clamp 4513 slides outward at the horizontal part at the top of the limiting groove 4511. After the limiting top block 4512 slides outward, it presses the side of the bearing seat to achieve the final clamping and fixing of the bearing seat.

[0078] After the bearing housing is fixed, the slide table 3 drives the support seat 31 and the bearing housing to slide inside the equipment frame 1, and then the machining head 11 performs drilling and milling on the surface of the bearing housing.

[0079] After the bearing housing is processed, the slide table 3 drives the support seat 31 and the bearing housing support plate 4 to move to the initial position. At this time, the bearing housing support plate 4 is once again inserted into the mounting frame 21. Then, the lifting cylinder 321 is controlled to descend, and the lifting cylinder 321 drives the support plate 32 to descend. At this time, the top block 46, the ring seat 45 and the transmission seat 44 all move downward. At this time, the limit of the bearing housing is released. Then, the support plate bracket 2 drives the mounting frame 21 and the bearing housing support plate 4 to rotate again, so that the processed bearing housing and the bearing housing support plate 4 rotate to the outside of the equipment frame 1, so as to facilitate the subsequent unloading of the bearing housing.

[0080] Before the bearing housing is unloaded, the cleaning nozzle 23 at the bottom outer side of the partition cover 22 sprays compressed air to clean residual debris from the surface of the bearing housing. After the bearing housing is unloaded, the positioning clamp 431 descends to its lowest point due to gravity. At this time, the air guide groove 4311 at the top of the positioning clamp 431 is flush with the surface of the bearing housing support plate 4. Compressed air is then sprayed out by the air nozzle 4312 in the air guide groove 4311. The compressed air flows along the surface of the bearing housing support plate 4 to blow away and clean residual debris and cutting fluid from the surface of the bearing housing support plate 4. As compressed air flows along the bearing seat support plate 4, it is guided by the annular groove 411 at the bottom outer side of the positioning shaft 41 and moves along the surface of the positioning shaft 41 to clean the surface of the positioning shaft 41. After the air nozzle 4312 sprays compressed air for a period of time, the cleaning nozzle 23 at the bottom outer side of the partition cover 22 sprays compressed air again to achieve secondary cleaning of the surface of the bearing seat support plate 4. After the surface of the bearing seat support plate 4 is cleaned, the subsequent bearing seats can be placed, and the above steps can be repeated to complete the continuous processing of the bearing seats.

The machining head 11 and other structures in the drilling and milling center adopt the corresponding structures in the prior art. No restrictions are imposed on them while ensuring the normal implementation of this embodiment.

[0082] It should be further explained that in this embodiment, both the cleaning nozzle 23 and the jet nozzle 4312 are connected to the air compressor to ensure the discharge of compressed air. Furthermore, both the cleaning nozzle 23 and the jet nozzle 4312 are equipped with solenoid valves between themselves and the air compressor to control the discharge of compressed air. The solenoid valves are controlled by a PLC controller. The PLC controller adopts the corresponding model in the prior art and has a preset control program adapted to this technical solution.
