Description

Technical Field

[0001] This invention relates to the field of bearing manufacturing technology, and in particular to a pressure testing device for deep groove ball bearings. Background Technology

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. Deep groove ball bearings are the most common type of rolling bearings. They mainly consist of an outer ring, an inner ring, a set of steel balls, and a cage. Before leaving the factory, bearings undergo a pressure resistance test to check their pressure resistance.

[0003] Existing pressure testing equipment places the bearings directly on the platform during positioning. Under high pressure during the pressure test, unqualified bearings may break apart. Fragments may hit the internal sensors or transmission pipelines of the equipment, causing damage. There is also a possibility that flying fragments may injure the operators. In addition, after the pressure test is completed, the bearings need to be stored in the warehouse together. During the waiting time for storage, the bearings may be affected by the moisture in the workshop, causing oxidation on the surface of the bearings and affecting their subsequent use.

[0004] Therefore, this application provides a pressure testing device for deep groove ball bearings to meet the requirements. Summary of the Invention

[0005] The technical problem this invention aims to solve is to provide a pressure testing device for deep groove ball bearings. This addresses the issue that existing pressure testing devices place the bearings directly on a platform during positioning, leading to the bearings being subjected to high pressure during testing. This can cause unqualified bearings to shatter, with fragments potentially hitting internal sensors or transmission lines, damaging the equipment, or injuring operators from flying debris. Furthermore, after pressure testing, the bearings need to be stored in the same batch. During the waiting period, moisture in the workshop can cause oxidation on the bearing surface, affecting subsequent use.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A pressure testing device for deep groove ball bearings includes a housing, a placement platform on the inner side of the housing, an electric push rod on the top inner wall of the housing, a high-speed camera on the right inner wall of the housing, a guide groove on the top of the placement platform, a pressure block connected to the bottom end of the electric push rod, and a screw connected to the bottom end of the pressure block. The device also includes a clamping assembly mounted on the placement platform for clamping the bearing, an anti-splash assembly mounted on one side of the electric push rod for preventing bearing breakage and splashing, and an oiling assembly installed inside the housing for applying oil to protect qualified bearings.

[0008] Optionally, the clamping assembly includes a rotary table, which is nested inside the placement platform and rotates with damping inside the placement platform.

[0009] Optionally, four sets of limiting grooves are evenly distributed on the outer side of the rotary table. A slider is nested inside the inner side of each set of limiting grooves. Each set of sliders slides inside the corresponding limiting groove. A support block is connected to the top of the slider.

[0010] Optionally, a connecting plate is connected to one side of the support block, and a threaded collar is connected between the four sets of connecting plates. An installation sleeve is installed on the top of the rotary table, and the threaded collar is nested and installed inside the installation sleeve, and the threaded collar slides inside the installation sleeve.

[0011] Optionally, the splash-proof assembly includes a rack, which is mounted on one side of the electric push rod and meshes with a gear, which is mounted on one side of the placement platform.

[0012] Optionally, the first gear meshes with the second rack, one end of the second rack is connected to a connecting frame, and the end of the connecting frame is symmetrically connected to a second slider. The second slider slides inside the guide groove, and the outer side of the second slider is connected to a second connecting plate, which rotates outside the second slider.

[0013] Optionally, a connecting plate three is connected to the tail end of the connecting plate two, the connecting plate three rotates at the end of the connecting plate two, a slider three is connected to the tail end of the connecting plate three, a barrier curtain is connected to the top of the slider two and the slider three, and the slider three slides inside the guide groove.

[0014] Optionally, the oiling assembly includes a slider four, which is nested inside the guide groove and slides inside the guide groove. A connecting plate four is connected to the outside of the slider four, and the tail end of the connecting plate four is connected to the slider three. An oiling roller is connected to the top end of the connecting plate four and slides with damping on the connecting plate four. The oiling roller is connected to an electrically controlled valve through a pipeline.

[0015] Optionally, a storage tank is connected to one side of the electrically controlled valve. The storage tank is installed on the inner wall of the box body and inside the box body. A fixing plate is installed inside the storage tank. A drain plate is nested inside the storage tank and located below the fixing plate. The drain plate rotates inside the storage tank. The bottom end of the drain plate is connected to a bevel gear set via a connecting rod.

[0016] Optionally, one of the bevel gears in the bevel gear set meshes with a bevel gear disk, the bevel gear disk is mounted on the bottom end of the rotary table, one of the bevel gears in the bevel gear set has a one-way gear connected to its end, the one-way gear rotates on the inner support of the housing, the one-way gear meshes with rack three, and rack three is mounted on one side of the electric push rod.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] In the above solution, by setting up anti-splash components, the sliding of sliders two and three inside the guide groove controls the opening and closing of the barrier curtain. When the bearing breaks, the fragments are blocked by the TPU barrier curtain, preventing the fragments from puncturing the internal sensors or transmission pipelines of the equipment and causing damage to the equipment. It also avoids the possibility of the bearing fragments injuring the operators. At the same time, the blocked debris falls onto the rotating table, making it convenient for the operators to collect and clean, ensuring the cleanliness of the inside of the equipment.

[0019] By setting up an oiling assembly, the oil drips to the bottom of the storage tank through the self-rotation alignment of the drip plate with the holes in the fixed plate. After being filled through the electrically controlled valve, the protective oil can be effectively saved. At the same time, the contact between the self-rotation of the drip plate and the fixed plate prevents the protective oil from settling to the bottom, avoiding oil deterioration. In addition, the secondary filtration of the aligned holes allows for the removal of viscous oil that has settled to the bottom, improving practicality and increasing the utilization rate of the oil.

[0020] By incorporating a clamping assembly, the bearing's inner bore is clamped and fixed using a support block, improving the bearing's stability during pressure testing. This facilitates the installation and removal of the bearing by operators, prevents relative sliding between the bearing and the pressure block, which could lead to inaccurate pressure testing, and improves testing efficiency.

[0021] By incorporating anti-splash and oiling components, and simultaneously driving the operation of both components via the vertical movement of an electric actuator, the complexity of the equipment's transmission mechanism is reduced, thus lowering maintenance costs.

[0039] The compressive strength testing device for deep groove ball bearings provided by the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0040] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0041] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0042] It is understood that the meanings of “on”, “above”, and “above” in this invention should be interpreted in the broadest manner, such that “on” means not only “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” means not only “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0043] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings. Spatially related terms are intended to cover different orientations in the use or operation of the device other than those depicted in the accompanying drawings. The device may be oriented in other ways, and the spatially related descriptive terms used herein can be interpreted similarly.

[0044] like Figures 1 to 13 As shown, an embodiment of the present invention provides a pressure testing device for deep groove ball bearings, including a housing 1, a placement platform 2 provided on the inner side of the housing 1, an electric push rod 3 provided on the top inner wall of the housing 1, a high-speed camera 4 provided on the right inner wall of the housing 1, a guide groove 8 provided on the top of the placement platform 2, a pressure block 9 connected to the bottom end of the electric push rod 3, a screw 10 connected to the bottom end of the pressure block 9, a clamping assembly 5 installed on the placement platform 2 for clamping the bearing, an anti-splash assembly 6 installed on one side of the electric push rod 3 for preventing the bearing from breaking and splashing, and an oiling assembly 7 installed inside the housing 1 for applying oil to protect qualified products.

[0045] like Figures 1 to 4 As shown, the clamping assembly 5 includes a rotating platform 51, which is nested inside the placement platform 2. The rotating platform 51 rotates with damping inside the placement platform 2. Four sets of limiting grooves 52 are evenly distributed on the outer side of the rotating platform 51. A slider 53 is nested inside the limiting groove 52. Each slider 53 slides inside the corresponding limiting groove 52. A support block 54 is connected to the top of the slider 53. A connecting plate 55 is connected to one side of the support block 54. Threaded collars 56 are connected between the four sets of connecting plates 55. An installation sleeve 57 is installed on the top of the rotating platform 51. The threaded collar 56 is nested inside the installation sleeve 57 and slides inside the installation sleeve 57.

[0046] By setting the clamping assembly 5, the operator places the deep groove ball bearing to be tested on the placement platform 2, so that the inner hole of the bearing fits around the outside of the four sets of support blocks 54. The cabinet door of the housing 1 is closed, and the electric push rod 3 is started using the control module (not shown in the figure). The electric push rod 3 pushes the pressure block 9 vertically downward to move it. The pressure block 9 continuously applies compressive force to the bearing to test its compressive strength. During the downward movement of the screw 10 at the bottom of the pressure block 9, the screw 10 meshes with the threaded collar 56. The screw 10 rotates at the bottom of the pressure block 9, and the threaded collar 56 slides within the mounting sleeve 57. The sliding of ring 56 causes connecting plate 55 to rotate outside the threaded collar 56. The tail end of connecting plate 55 pushes support block 54, causing slider 53 to slide inside the limiting groove 52. This allows support block 54 to move towards the inner hole of the bearing, clamping the bearing's inner hole and preventing lateral sliding of the bearing from detaching from the placement platform 2 during pressure testing, which would affect the test structure. By using support block 54 to clamp and fix the bearing's inner hole, the stability of the bearing during pressure testing is improved, making it easier for operators to load and unload the bearing. This also prevents relative sliding between the bearing and pressure block 9, which could lead to inaccurate pressure testing and improves testing efficiency.

[0047] like Figures 5 to 9 As shown, the anti-splash assembly 6 includes a rack 61, which is mounted on one side of the electric push rod 3. The rack 61 meshes with a gear 62, which is mounted on one side of the placement platform 2. The gear 62 meshes with a rack 63. One end of the rack 63 is connected to a connecting frame 64. The end of the connecting frame 64 is symmetrically connected to a slider 65, which slides inside the guide groove 8. The outside of the slider 65 is connected to a connecting plate 66, which rotates outside the slider 65. The tail end of the connecting plate 66 is connected to a connecting plate 67, which rotates at the end of the connecting plate 66. The tail end of the connecting plate 67 is connected to a slider 68. The top ends of the sliders 65 and 68 are connected to a barrier curtain 69, which is made of TPU woven fabric. The slider 68 slides inside the guide groove 8.

[0048] By setting the anti-splash component 6, during the downward movement of the electric push rod 3, the rack 61 moves vertically downward. The gear 62 rotates by meshing with the rack 61. The gear 62 meshes with the rack 63, causing the rack 63 to drive the connecting frame 64 to slide to the right. The connecting frame 64 pushes the slider 65 to slide inside the guide groove 8, causing the barrier curtain 69 on the slider 65 to move accordingly. During the movement, the slider 65 rotates through the connecting plate 66 connected to the outside. The lever arm formed by the rotation of the connecting plate 66 at the end of the connecting plate 67 allows the slider 65 to move within the guide groove 8 through the force between the connecting plate 66 and the connecting plate 67. The arm pushes slider 68 to slide inside the guide groove 8, opening the barrier curtain 69 to shield the bearing undergoing pressure testing. This prevents fragments from flying out after the bearing breaks under pressure, thus preventing injury to the operator. Sliding sliders 65 and 68 inside the guide groove 8 control the opening and closing of the barrier curtain 69. When the bearing breaks, the fragments are blocked by the TPU barrier curtain 69, preventing them from puncturing the internal sensors or transmission lines and causing equipment damage. This also avoids the possibility of bearing fragments injuring the operator. At the same time, the blocked debris falls onto the rotary table 51, making it easy for the operator to collect and clean, ensuring the cleanliness of the equipment's interior.

[0049] like Figures 10 to 13 As shown, the oiling assembly 7 includes a slider 4 71, which is nested inside the guide groove 8 and slides within the guide groove 8. A connecting plate 4 710 is connected to the outer side of the slider 4 71, and the tail end of the connecting plate 4 710 is connected to a slider 3 68. An oiling roller 72 is connected to the top of the connecting plate 4 710 and slides with damping on the connecting plate 4 710. The oiling roller 72 is connected to an electrically controlled valve 730 via a pipeline. A storage tank 73 is connected to one side of the electrically controlled valve 730 and is installed on the inner wall of the housing 1. The storage tank 73 is installed inside the housing 1. A fixing plate 74 is installed on the inner side of the storage tank 73, and a drain plate 75 is nested inside the storage tank 73. The drain plate 75 is located below the fixing plate 74 and rotates inside the storage tank 73. The bottom end of the drain plate 75 is connected to a bevel gear set 76 via a connecting rod. One bevel gear in the bevel gear set 76 meshes with a bevel gear disk 77. The bevel gear disk 77 is installed at the bottom end of the rotary table 51. One bevel gear in the bevel gear set 76 is connected to a one-way gear 78 at its end. The one-way gear 78 rotates on the bracket inside the housing 1. The one-way gear 78 meshes with a rack 3 79. The rack 3 79 is installed on one side of the electric push rod 3.

[0050] By setting the oiling assembly 7, when slider 3 68 slides inside the guide groove 8, slider 3 68 pushes slider 4 71 to slide inside the guide groove 8 through connecting plate 4 710, entering the straight groove tail end of the guide groove 8, causing the oiling roller 72 to move away from the bearing, avoiding interference with the pressure test. After the pressure test is completed, the electric push rod 3 is controlled to move upward through the control module (not marked in the figure), driving rack 3 79 to move upward. Rack 3 79 meshes with one-way gear 78, and one-way gear 78 rotates with bevel gear set 76 at the bottom of the placement platform 2. One bevel gear in bevel gear set 76 meshes with bevel gear disk 77, driving the rotary table 51 to rotate, causing the bearing to rotate with the rotary table 51. High-speed camera 4 passes through. By photographing and identifying the bearing surface to determine its integrity, when the bevel gear set 76 rotates, one of the bevel gears in the bevel gear set 76 drives the drain plate 75 to rotate inside the storage tank 73 via the transmission rod. When the drain plate 75 aligns with the hole on the fixed plate 74, the protective oil drips into the bottom of the storage tank 73. Through the rotation of the drain plate 75 and its alignment with the hole on the fixed plate 74, the oil drips to the bottom of the storage tank 73 and is then added through the electrically controlled valve 730. This effectively saves protective oil while preventing it from settling at the bottom through the contact between the drain plate 75 and the fixed plate 74, thus avoiding oil deterioration. At the same time, the secondary filtration through the aligned holes removes viscous oil with sediment, improving practicality and increasing the utilization rate of the oil.

[0051] The working principle of the technical solution provided by this invention is as follows:

[0052] The operator places the deep groove ball bearing to be tested on the placement platform 2, so that the inner hole of the bearing fits on the outside of the four sets of support blocks 54. The cabinet door of the box 1 is closed, and the electric push rod 3 is started using the control module (not marked in the figure). The electric push rod 3 pushes the pressure block 9 vertically downward to move it. The pressure block 9 continuously applies extrusion pressure to the bearing to test its compressive strength. During the downward movement of the screw 10 at the bottom of the pressure block 9, the screw 10 and the threaded collar 56 mesh with each other. The screw 10 rotates at the bottom of the pressure block 9, and the threaded collar 56 slides within the mounting sleeve 57. As the threaded collar 56 slides, the connecting plate 55 rotates outside the threaded collar 56. The tail end of the connecting plate 55 pushes the support block 54, so that the slider 53 slides within the limiting groove 52. This causes the support block 54 to move towards the inner hole surface of the bearing, clamping the inner hole of the bearing and preventing the bearing from sliding laterally and detaching from the placement platform 2 during the pressure test, thus affecting the test structure.

[0053] During the downward movement of the electric push rod 3, it drives rack 61 to move vertically downward. Gear 62 rotates by meshing with rack 61. Gear 62 meshes with rack 63, causing rack 63 to drive connecting frame 64 to slide to the right. Connecting frame 64 pushes slider 65 to slide inside guide groove 8, causing the barrier curtain 69 on slider 65 to move accordingly. During the movement, slider 65 rotates through connecting plate 66 connected to the outside. The lever arm formed by the rotation of connecting plate 66 at the end of connecting plate 67 causes slider 65 to move inside guide groove 8. The lever arm between connecting plate 66 and connecting plate 67 pushes slider 68 to slide inside guide groove 8, opening the barrier curtain 69 and shielding the bearing undergoing pressure testing. This prevents the bearing from breaking under pressure and causing fragments to fly, thus preventing injury to the operator.

[0054] When slider 68 slides inside guide groove 8, slider 68 pushes slider 71 to slide inside guide groove 8 via connecting plate 710, entering the straight groove end of guide groove 8, causing oiling roller 72 to move away from bearing, avoiding interference with pressure test. After pressure test, the control module (not shown in the figure) controls electric push rod 3 to move upward, driving rack 79 to move upward. Rack 79 meshes with one-way gear 78, and one-way gear 78 meshes with bevel gear set 76 on placement platform 2. The bottom end rotates, and one of the bevel gears in the bevel gear set 76 meshes with the bevel gear disk 77 to drive the rotary table 51 to rotate, causing the bearing to rotate with the rotary table 51. The high-speed camera 4 takes pictures of the bearing surface to identify whether the bearing surface is intact. When the bevel gear set 76 rotates, one of the bevel gears in the bevel gear set 76 drives the drain plate 75 to rotate inside the storage tank 73 through the transmission rod. When the drain plate 75 aligns with the hole on the fixed plate 74, the protective oil drips into the bottom of the storage tank 73.

[0055] If the bearing surface is intact, the control module activates the electronically controlled valve 730, allowing oil to enter the oiling roller 72 through the valve and pipeline. The oiling roller 72 moves upward via the electric push rod 3, causing rack 61 and gear 62 to mesh. Gear 62 rotates on one side of the placement platform 2, meshing with rack 63, which pulls the connecting frame 64 in the opposite direction. This causes slider 65 to slide in the guide groove 8 towards its initial position. The lever arm between connecting plate 66 and connecting plate 67 pulls slider 68 towards its initial position, causing the barrier curtain 69 to retract. Simultaneously, under the pull of slider 68, connecting plate 710 moves slider 71 from the straight groove of the guide groove 8 back to its initial position near the bearing. This allows the oiling roller 72 to apply protective oil to the intact bearing surface, preventing rust and oxidation and facilitating storage.
