Description

Technical Field

[0001] This utility model relates to the technical field of automatic oilstone adjustment devices, specifically an automatic adjustment device for the extension length of an ultra-fine oilstone. Background Technology

[0002] Currently, in the ultra-precision machining of bearing raceways, after a period of use, the new honing stone will wear down, resulting in insufficient contact between the honing stone and the raceway, or even the honing stone not being able to contact the raceway surface due to its excessively short extension length, thus producing defective ultra-precision products. At this time, the machining personnel need to stop the machine frequently to check the length of the honing stone according to the machining quality, and manually press the honing stone pressure rod to push the honing stone downward. If the extension length of the honing stone is not adjusted in time during this process, many defective ultra-precision products will be produced. At the same time, if the honing stone is found to be too short before it is fully utilized, a new honing stone will be replaced immediately, resulting in insufficient utilization and waste of the honing stone. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an automatic adjustment device for the extension length of an ultra-fine oilstone, which solves the problem of poor contact between the oilstone and the product being processed due to the failure to adjust the extension length of the oilstone in time or excessive wear of the oilstone during processing.

[0004] To achieve the above objectives, this utility model provides an automatic adjustment device for the extension length of an ultra-precise oilstone, including an oilstone and a mounting base for mounting on an external bearing processing equipment. The mounting base has an adjustment groove along its height direction for the oilstone to slide. The beginning end of the oilstone extends through the end opening of the adjustment groove. A pressure plate for pressing the end of the oilstone is slidably disposed in the adjustment groove. The mounting base is provided with a driving component for linkage with an external hydraulic drive device to apply a load to the oilstone through the pressure plate, and a guide component for linkage with the driving component to guide the load loading position and direction. The pressure plate is provided with a detection component for detecting the degree of contact between the beginning end of the oilstone and the groove of the external bearing race, and a positioning component for guiding and positioning the sliding direction of the oilstone.

[0005] The advantages of the above technical solution are: The honing stone is installed in the adjusting groove, and its sliding direction within the groove is limited by a positioning component. Then, the driving component is linked with an external hydraulic drive device, and the bottom wall of the pressure plate abuts against the end of the honing stone. When the honing stone wears or its extension length is insufficient, poor or insufficient contact may occur between the honing stone's starting end and the external product to be processed. The detection component can detect the degree of contact between the honing stone's starting end and the external product to be processed, i.e., the contact strength between the honing stone's starting end and the bearing ring groove to be processed. When the detection component detects poor or insufficient contact, it generates a signal and transmits it to the external hydraulic drive device, causing the device to start and apply a load to the pressure plate through the driving component. This load is applied to the end of the honing stone through the pressure plate, thus allowing the honing stone to pass through the pressure plate. This technology ensures that the starting end of the whetstone can contact the workpiece, thereby increasing the contact strength between the whetstone and the workpiece. This design allows the whetstone to maintain contact even when its extension length is too short or its wear is excessive, thus improving processing efficiency and accuracy. Furthermore, it eliminates the need for immediate replacement of the whetstone when it is too short, ensuring its complete utilization and preventing underutilization or waste. The guide component guides the load application direction to prevent uneven force distribution on the whetstone, which could lead to insufficient contact between the whetstone and the workpiece. The positioning component guides the sliding direction of the whetstone, preventing it from shaking, loosening, or slipping between the starting end and the workpiece, further improving processing efficiency and accuracy.

[0006] The present invention further comprises: the driving component includes a driving plate, the top wall of the driving plate is provided with a force-bearing rod for connecting to the output end of an external hydraulic driving device, the bottom wall of the driving plate is in abutting fit with the top wall of the pressure plate, and the two side walls of the driving plate are respectively in contact with the inner walls of the two sides of the adjusting groove.

[0007] The advantages of adopting the above technical solution are: when the external hydraulic drive equipment is started, its output end will apply a load to the force rod, causing the force rod to drive the drive plate to move down and abut against the top wall of the pressure plate, and continuously apply a load to the pressure plate to drive the pressure plate to move in the adjustment groove, thereby realizing the load of the pressure plate on the oilstone; in the above technology, the two side walls of the drive plate are respectively set to contact the two side inner walls of the adjustment groove, so as to realize the limiting and guiding of the sliding of the drive plate by the adjustment groove.

[0008] The present invention further includes the following features: the guide includes a guide shaft disposed on the back of the drive plate; a guide groove is provided on the inner wall of the adjustment groove along the height direction of the mounting base; a guide block extends from the guide shaft toward the guide groove; the radial cross section of the guide groove is trapezoidal; the guide block is adapted to the shape of the guide groove; and the guide block is slidably disposed in the guide groove.

[0009] The advantages of adopting the above technical solution are: the cooperation between the guide block and the guide groove enables the guide block to slide in the guide groove and limit the guide block. At the same time, the radial cross section of the guide groove is set in a trapezoidal shape and the guide block is set to match the shape of the guide groove, so that the guide block is restricted by the guide groove and is difficult to shake or loosen. This achieves the limitation and positioning of the drive plate, so as to avoid uneven loading of the load applied by the drive plate to the pressure plate or the phenomenon of the drive plate shaking or loosening, thereby avoiding the impact on the contact accuracy between the oilstone and the external product to be processed.

[0010] The present invention further includes the following: the detection element includes a pressure sensor disposed inside the pressure plate, the detection end of the pressure sensor protruding from the bottom wall of the pressure plate and engaging with the end of the whetstone.

[0011] The advantages of adopting the above technical solution are: The pressure sensor detects the force applied by the oilstone to the pressure plate in real time, and when the applied force fluctuates frequently or the fluctuation amplitude is too large, it transmits a signal to an external intelligent industrial control system, which then starts the hydraulic drive equipment, thereby improving the connection strength between the oilstone and the external product to be processed. The intelligent industrial control system or equipment mentioned above is existing technology and can be an industrial computer, etc. Because it is existing technology, its structure, function, and communication connection with the pressure sensor will not be described in detail. The hydraulic drive equipment mentioned above is also existing technology and can be an electric actuator or cylinder, etc., with vertical drive function. Because it is existing technology, its structure and function will not be described in detail.

[0012] The present invention further includes: the positioning element includes a positioning seat disposed in the adjustment groove, the positioning seat having a through groove through which the end of the oilstone passes, the through groove being adapted to the oilstone, and the inner peripheral wall of the through groove being in contact with the outer peripheral wall of the oilstone.

[0013] The advantage of adopting the above technical solution is that the positioning seat and the through groove are used to limit the movement of the oilstone, thereby guiding and positioning the direction of the oilstone's extension.

[0014] The present invention further includes: the positioning component also includes positioning springs disposed on both sides of the whetstone, the two positioning springs are disposed in the adjustment groove and the inner walls on both sides of the adjustment groove are respectively provided with openings corresponding to the positions of the two positioning springs, the ends of the positioning springs are located in the corresponding openings and are connected to the inner walls of the openings, and the starting ends of the positioning springs are abutting ends for abutting and cooperating with the side walls of the whetstone.

[0015] The advantages of adopting the above technical solution are: the positioning springs arranged in opposite directions realize the torque loading of the oilstone and guide and position the oilstone's extension direction, thereby improving the contact strength and contact accuracy between the oilstone and the external product to be processed.
