Description

Technical Field

[0001] The utility model relates to the technical field of part detection, in particular to an automobile bearing pressure detection tooling. Background Technique

[0002] Bearings are key components used in mechanical equipment to support rotating shafts and reduce friction. They can be divided into two categories: rolling bearings and sliding bearings. Among them, rolling bearings are widely used in various machinery due to their lower friction coefficient and higher rotational speed capacity. An automobile bearing pressure detection tooling is a device specifically used to detect the performance and state of bearings when they are under pressure. This tooling is crucial for ensuring the quality of automobile bearings and the safe operation of vehicles. By conducting pressure tests and adjustments on the bearings, key performance indicators such as the bearing capacity, friction coefficient, and rotational resistance of the bearings can be evaluated, thereby ensuring the stability and reliability of the bearings under actual working conditions.

[0003] The traditional automobile bearing pressure detection tooling consists of a bottom plate, an adjustment structure, a pressing block, etc. The bearing is placed in the placement cavity. The position of the pressing block is adjusted through the adjustment structure to make it contact with the bearing. The pressing block is pushed by a hydraulic rod to apply radial pressure to the bearing. After applying the pressure, the detector built into the tooling will measure the tiny strain generated by the bearing when it is under force and convert these strains into electrical signals, thereby calculating the pressure value borne by the bearing.

[0004] Due to the poor fixity of the traditional automobile bearing pressure detection tooling to the bearing, the bearing is prone to moving and rotating when being squeezed, thus affecting the accuracy of pressure detection.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Referring to Figures 1 - 3 , an embodiment provided by the present invention: an automotive bearing pressure detection tooling, including a base 1, a support plate 2 is fixedly connected to the upper surface of the base 1, a top plate 3 is fixedly connected to the upper surface of the support plate 2, a mounting plate 7 is fixedly connected to the upper surface of the base 1, a motor 8 is fixedly connected to the upper surface of the mounting plate 7, a rotating column 9 is fixedly connected to the output end of the motor 8, a workbench 6 is arranged on the upper surface of the base 1, a first fixing block 10 is fixedly connected to the inside of the workbench 6, the side wall of the rotating column 9 is rotatably connected to the inside of the first fixing block 10, a rotating plate 11 is fixedly connected to the side wall of the rotating column 9, the side wall of the rotating plate 11 is rotatably connected to the inside of the workbench 6, a chute 14 is opened in the inside of the workbench 6, a rotating bar 12 is rotatably connected to the lower surface of the rotating plate 11, one end of the rotating bar 12 is rotatably connected to a sliding block 13, the side wall of the sliding block 13 is slidably connected to the inside of the chute 14, a clamping plate 15 is fixedly connected to the upper surface of the sliding block 13, a support assembly for supporting the workbench 6 is arranged on the upper surface of the base 1, and the support assembly includes a support column 5, one end of the support column 5 is fixedly connected to the upper surface of the base 1, and the other end of the support column 5 is fixedly connected to the lower surface of the workbench 6;

[0034] In the process of bearing pressure detection, first, the bearing to be detected needs to be placed at the central position of the workbench 6 of the device. Subsequently, the operator needs to start the motor 8. The operation of the motor 8 will drive the connected rotating column 9 to start rotating. The rotational movement of the rotating column 9 will be transmitted to the rotating plate 11, causing it to also start rotating. The rotation of the rotating plate 11 will further drive the connected rotating bar 12 to rotate. The rotational movement of the rotating bar 12 will cause the connected slider 13 to slide towards the central position along the inside of the chute 14. The sliding of the slider 13 will push the clamping plate 15 slowly towards the bearing until the side wall of the clamping plate 15 is in contact with the side wall of the bearing. When the side wall of the clamping plate 15 is completely in contact with the side wall of the bearing, the bearing is fixed, and at this time, the next pressure detection operation can be carried out.

[0035] Refer to Figures 4 - 5 , a detector 4 is fixedly connected to the upper surface of the top plate 3. A hydraulic rod 16 is fixedly connected to the lower surface of the top plate 3. The output end of the hydraulic rod 16 is fixedly connected to a connecting plate 17. A pressing plate 18 is arranged on the lower surface of the connecting plate 17. A cylindrical housing 19 is slidably connected inside the connecting plate 17. A pressing column 20 is slidably connected inside the cylindrical housing 19. A pulling plate 21 is fixedly connected to the side wall of the pressing column 20. A second fixing block 22 is fixedly connected to the side wall of the pressing column 20. The side wall of the second fixing block 22 is slidably connected inside the cylindrical housing 19. A spring 23 is sleeved on the side wall of the pressing column 20. One end of the spring 23 is fixedly connected inside the cylindrical housing 19, and the other end of the spring 23 is fixedly connected to the side wall of the second fixing block 22. A sliding column 24 is fixedly connected to the lower surface of the pressing column 20. A fixing column 25 is fixedly connected to the lower surface of the sliding column 24. An extrusion block 26 is fixedly connected to the side wall of the fixing column 25. A bottom block 27 is fixedly connected to the lower surface of the fixing column 25. A sliding ball 28 is arranged inside the cylindrical housing 19. The side wall of the extrusion block 26 is slidably connected to the side wall of the sliding ball 28. The side wall of the sliding ball 28 is slidably connected inside the pressing plate 18.

[0036] After the bearing is installed and fixed in place, next, start the hydraulic rod 16. The start of the hydraulic rod 16 will push the connecting plate 17 downward, thereby causing the pressing plate 18 to apply pressure to the bearing. The extrusion force applied by the pressing plate 18 is finally received by the detector 4. The detector 4 is an existing device and will not be elaborated here again.

[0037] When the pressing plate 18 is worn out after long-term use and needs to be replaced, the operator first needs to press down the pressing column 20. This action will cause the fixed block 22 to apply pressure to the spring 23 to compress it. Then, the sliding column 24 will be pushed, thereby prompting the extrusion block 26 to move downward. This series of actions causes the sliding ball 28 to lose its extrusion. At this time, the cylindrical shell 19 is lifted up. The lifting action will cause the sliding ball 28 to be squeezed and slide into the interior of the cylindrical shell 19 and get stuck between the extrusion block 26 and the sliding column 24. At this time, the cylindrical shell 19 is removed from the equipment. At this time, the fixing relationship between the pressing plate 18 and the connecting plate 17 is released, so that the pressing plate 18 can be removed.

[0038] Working principle: When using the equipment to detect the bearing pressure, first place the bearing in the middle of the workbench 6, then start the motor 8 to make the rotating column 9 start to rotate, and then drive the rotating plate 11 to rotate, and the rotating bar 12 is driven to rotate by the rotation of the rotating plate 11, so that the sliding block 13 connected thereto slides toward the middle inside the slide groove 14, and the clamping plate 15 slowly approaches the bearing until the side wall of the clamping plate 15 fits the side wall of the bearing, and the bearing is fixed at this time. When the bearing is fixed, start the hydraulic rod 16 to push the connecting plate 17 downward, so that the pressing plate 18 squeezes the bearing, and the pressing plate 18 The extrusion force will eventually be transmitted to the detector 4, thereby completing the bearing pressure detection work. When the pressing plate 18 is worn and needs to be replaced, first press down the pressing column 20 to make the fixed block 22 squeeze the spring 23 to make it shrink, and at the same time let the sliding column 24 push the extrusion block 26 to move downward, so that the sliding ball 28 loses the extrusion. At this time, by lifting the cylindrical shell 19, the sliding ball 28 is squeezed and slides into the inside of the cylindrical shell 19, and is stuck between the extrusion block 26 and the sliding column 24, so that the cylindrical shell 19 is taken out. At this time, the pressing plate 18 loses its fixation with the connecting plate 17, thereby completing the disassembly of the pressing plate 18.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
