Description

Technical Field

[0001] This utility model relates to the field of bearing housing processing technology, and in particular to an online detection device for bearing housing electrolytic grinding processing. Background Technology

[0002] Electrolytic grinding of bearing housings is a precision machining technique that utilizes electrolysis. This technique is typically used for ultra-precision machining of difficult-to-cut materials, especially for metals with high hardness, strength, and wear resistance, such as cemented carbide and high-speed steel. During electrolytic grinding, the workpiece (in this case, the bearing housing) acts as the anode, and the tool electrode acts as the cathode. Under the influence of the electrolyte, a direct current is applied, causing an electrochemical reaction on the workpiece surface, thereby dissolving and removing trace amounts of metal material to achieve the grinding purpose. Simultaneously, the tool electrode contacts or approaches the workpiece surface at a certain speed and pressure, helping to remove the passivation film generated by the electrochemical reaction and promoting electrolyte renewal to ensure the continuity and stability of the machining process.

[0003] After machining, existing bearing housing electrolytic grinding equipment typically requires removing the bearing housing from the equipment and transferring it to an inspection station for quality testing. This step-by-step operation not only increases the time cost of manual handling and loading / unloading but also reduces overall processing efficiency. Furthermore, if some bearing housings are found to be substandard during inspection, they must be reinstalled in the machining equipment for rework, further extending the production cycle and affecting the continuity of the processing flow.

[0004] Furthermore, during electrolytic grinding, uneven electrolyte flow or residue often results in metal oxides, electrolytic residues, or other impurities adhering to the bearing housing surface. These residues can affect testing accuracy and even mislead test results. Therefore, an additional cleaning step is often required before formal testing, using manual labor or auxiliary equipment to clean the bearing housing surface. This undoubtedly increases the operational steps and labor intensity, making it inconvenient to use. Utility Model Content

[0005] The purpose of this invention is to provide an online inspection device for electrolytic grinding of bearing housings. This device avoids the problems of existing electrolytic grinding equipment requiring manual disassembly and transfer to the inspection station after processing, and re-clamping and repair of unqualified bearing housings, which affects processing efficiency. Furthermore, electrolyte residue can easily lead to surface impurities, interfering with inspection accuracy, requiring additional cleaning steps, which is cumbersome, labor-intensive, and inconvenient to use.

[0006] This utility model provides an online inspection device for electrolytic grinding of bearing housings, including a lathe. The lathe has an inner cavity equipped with an inspection component, which includes three fixed plates and a connecting box. A gear plate is fixedly connected to the inner cavity of the connecting box. Two symmetrically arranged push plates are slidably connected to the inner cavity of the connecting box.

[0009] In one specific implementation, the front sides of the threaded plate and the movable plate are respectively fixedly connected to the surface of the connecting box, and the top of the threaded plate is fixedly connected to the placement box.

[0010] In one specific implementation, a positioning box is fixedly connected to the top of the mounting box, and a first motor is fixedly connected to the inner cavity of the positioning box. The output shaft of the first motor is fixedly connected to the top end of the threaded rod.

The bottom end of the rotating rod passes through the inner cavity of the connecting box and is fixedly connected to one side of the two push plates opposite to each other.

[0012] In one specific implementation, a fixing rod is provided through the inner side of the push plate, and a detection component is installed at the bottom end of the fixing rod.

[0013] In one specific implementation, a grinding device is installed in the inner cavity of the lathe, and an electric guide rail is connected to the inner side of the lathe.

[0014] In one specific implementation, a clamp is movably connected to the surface of the electric guide rail, and a liquid spraying component is installed in the inner cavity of the lathe.

[0015] In one specific implementation, the movable plate is L-shaped.

[0016] The beneficial effects of this application are as follows: By setting up a detection component, online quality inspection of the bearing housing can be performed immediately after electrolytic grinding, eliminating the need for operators to remove the bearing housing from the processing unit and transfer it to the inspection station. This not only saves inspection time and improves work efficiency but also reduces errors and damage that may be caused by frequent disassembly and assembly. Simultaneously, the cleaning function of the detection component is activated during the inspection process to remove residual electrolyte, metal debris, and other impurities from the bearing housing surface, ensuring that the tested surface is clean and uncontaminated.

[0027] Existing bearing housing electrolytic grinding equipment requires manual disassembly and transfer to the inspection station after processing. If the inspection fails, re-clamping and repair are necessary, impacting processing efficiency. Furthermore, electrolyte residue can lead to surface impurities, interfering with inspection accuracy and requiring additional cleaning steps, resulting in cumbersome operation, high labor intensity, and inconvenience. Therefore, the inventors have developed an online inspection device for bearing housing electrolytic grinding. By incorporating a cleaning-functional inspection component, online inspection and surface cleaning of the bearing housing can be performed directly after electrolytic grinding, avoiding disassembly and transfer, improving inspection efficiency and accuracy, and achieving integrated processing, inspection, and cleaning operations. This enhances the equipment's practicality and solves the aforementioned shortcomings.

[0028] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] Please refer to Figures 1 to 8This utility model provides an online inspection device for electrolytic grinding of bearing housings, including a lathe 1. The lathe 1 has an inner cavity equipped with an inspection component 2, which includes three fixed plates 21 and a connecting box 211. The lathe 1 itself carries a moving component, and one side of each of the three fixed plates 21 is fixedly connected to the surface of the moving component. The fixed plates 21 are concave in shape. A gear 213 is fixedly connected to the inner cavity of the connecting box 211. Two symmetrically arranged push plates 214 are slidably connected to the inner cavity of the connecting box 211. A gear 218 meshes with the gear 213 within the inner cavity of the connecting box 211. A cleaning roller 217 extends through the inner cavity of the gear 218. The bottom of the connecting box 211 has an open structure, and the surface of the cleaning roller 217 is fixedly connected to the inner cavity of the gear 218. The bottom end of the cleaning roller 217 extends to the outer side of the bottom of the connecting box 211. The surface of plate 7 is rotatably connected to the inner side of push plate 214. The inner side of fixed plate 21 is fixedly connected to mounting box 22. The inner cavities of the three mounting boxes 22 are respectively connected to threaded rod 25 and guide rod 26. The threaded rod 25 is rotatably connected to the inner cavity of mounting box 22, and the surface of threaded rod 25 is provided with external thread. The surface of guide rod 26 is movably connected to moving plate 27. The surface of threaded rod 25 is threadedly connected to threaded plate 28. The area of ​​threaded plate 28 in contact with threaded rod 25 is provided with matching internal thread. The rear side of threaded plate 28 is slidably connected to the inner cavity of mounting box 22. The front side of mounting box 22 is provided with moving cavity. The front sides of threaded plate 28 and moving plate 27 are respectively fixedly connected to the surface of connecting box 211. The top of threaded plate 28 is fixedly connected to placement box 29. The top of mounting box 22 is fixedly connected to positioning box 23. The inner cavity of positioning box 23 is fixedly connected to first motor 24.

[0030] Please refer to Figures 2 to 8 The output shaft of the first motor 24 is fixedly connected to the top end of the threaded rod 25. The inner cavity of the placement box 29 is fixedly connected to the second motor 210. The output shaft of the second motor 210 is fixedly connected to the rotating rod 212. The bottom end of the rotating rod 212 passes through the inner cavity of the connecting box 211 and is fixedly connected to the opposite side of the two push plates 214. The inner side of the push plate 214 is provided with a fixing rod 215. The bottom end of the fixing rod 215 is equipped with a detection component 216, which is a visual inspection camera device, so as to facilitate surface inspection of the bearing seat after electrolytic grinding, thereby ensuring the quality of the bearing seat during the processing. The inner cavity of the lathe 1 is equipped with a grinding device 3. The inner side of the lathe 1 is connected to an electric guide rail 4. The rear side of the electric guide rail 4 is fixedly installed with the moving part of the inner cavity of the lathe 1. The surface of the electric guide rail 4 is movably connected to a clamp 5, which is responsible for clamping the bearing seat, so as to facilitate the grinding device 3 to perform processing.

[0031] Please refer to Figures 3 to 8The lathe 1 has a spraying component 6 installed in its inner cavity. The spraying component 6 works in conjunction with the grinding device 3 and the fixture 5. The spraying component 6 specifically includes a reservoir for storing electrolyte. The reservoir is fixedly connected to the top of the lathe 1. A feed pipe is connected to one side of the reservoir. The lathe 1 has a fixedly connected delivery pump, such as a diaphragm pump or a gear pump, for delivering electrolyte. The inlet and outlet ends of the delivery pump are connected to pipes. The inlet pipe is connected to the reservoir. The outlet pipe is connected to a nozzle, which is angled. During grinding, a certain grinding pressure is maintained between the grinding device 3 and the bearing seat held in the fixture 5. The non-conductive abrasive protruding from the surface of the grinding wheel in the grinding device 3 creates an electrolytic gap of about 0.02 to 0.05 mm between the workpiece surface and the conductive substrate of the grinding wheel. At the same time, electrolyte is supplied to the gap. Under the action of direct current, the metal on the workpiece surface generates ionic compounds and an anodic film due to electrolysis. These electrolytic products are continuously scraped away by the rotating grinding wheel, exposing new metal surfaces and continuing the electrolytic process. The workpiece material is thus continuously removed, achieving the grinding purpose. The electrolyte is generally an aqueous solution of sodium nitrate, sodium nitrite, and potassium nitrate. The composition of the electrolyte varies depending on the workpiece material. The conductive grinding wheel is made of a conductive matrix (bond) and abrasive. It is mainly composed of metal-bonded diamond grinding wheels, electroplated diamond grinding wheels, copper-based resin-bonded grinding wheels, ceramic silver-infiltrated grinding wheels, and carbon-bonded grinding wheels, etc., selected according to different applications. The moving plate 27 is L-shaped, and a displacement sensor is installed on the surface of the moving plate 27 to facilitate the confirmation of the height position of the detection component 216 and to facilitate the cleaning of the bearing seat surface.

[0032] Specifically, during the inspection after the bearing housing has been electrolytically ground, the first motor 24 is started. This first motor 24 drives the threaded rod 25 to rotate, which in turn drives the threaded plate 28 to move downward using the thread transmission principle. The threaded plate 28 then drives the connecting box 211, the cleaning roller 217, and the inspection component 216 to move downward synchronously.

[0033] The second motor 210 is then started, which drives the rotating rod 212 to rotate, thereby causing the two push plates 214 to rotate. The two push plates 214 drive the fixed rod 215 and the cleaning roller 217 to move synchronously. During the rotation of the cleaning roller 217, the gear 218 on it meshes with the gear disk 213 to achieve rotation, thereby effectively cleaning the surface of the bearing seat.

[0034] At the same time, the fixed rod 215 drives the detection component 216 to rotate synchronously, and performs quality inspection on the surface of the cleaned bearing seat to ensure that the quality of the electrolytic grinding process meets the requirements, so as to facilitate the smooth progress of subsequent processes.

[0035] In summary, the working principle of the online inspection device for electrolytic grinding of bearing housing according to this utility model embodiment is as follows: First, the user places the bearing housing into the fixture 5 for clamping. After clamping, the electric guide rail 4 is activated to move the bearing housing in front of the grinding device 3. At this time, the grinding device 3 and the liquid spraying component 6 are activated to perform electrolytic grinding on the bearing housing. After electrolytic grinding, the bearing housing is moved to the bottom of the inspection component 2 for inspection via the electric guide rail 4, thereby ensuring the quality of the bearing housing after processing. If the quality does not meet the inspection standards, the bearing housing can be electrolytically ground again for easy use.

[0036] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
