Description

Technical Field

[0001] This utility model relates to the field of bearing processing equipment technology, and more specifically, it relates to a spray cleaning device for semi-finished deep groove ball bearings. Background Technology

[0002] As a key component in mechanical transmission, deep groove ball bearings are prone to leaving a large amount of cutting fluid, metal shavings, emulsions, oil stains, and other impurities on their surfaces and in complex structures such as grooves, chamfers, and bores during machining processes such as turning, grinding, and heat treatment. If these impurities are not thoroughly removed, they will not only affect the dimensional accuracy and surface finish of subsequent precision machining, but may also exacerbate wear during bearing operation after assembly, shorten service life, and even cause equipment failure.

[0003] Currently, spray cleaning equipment for semi-finished deep groove ball bearings on the market has many shortcomings: First, some equipment places the workpiece directly at the bottom of the cleaning tank or in a regular tray, making it impossible to quickly separate the wastewater generated during the cleaning process from the workpiece. This causes impurities to repeatedly adhere to the workpiece surface with the wastewater, resulting in secondary pollution and affecting the cleaning effect. Second, most equipment has fixed spray nozzle positions and a single spray direction, which easily creates cleaning dead zones, leading to impurity residue. Only by adding more nozzles and spraying from different directions can this problem be avoided, which undoubtedly greatly increases the manufacturing cost of the cleaning equipment.

[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes a spray cleaning device for semi-finished deep groove ball bearings. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a spray cleaning device for semi-finished deep groove ball bearings.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a spray cleaning device for semi-finished deep groove ball bearings, comprising a cleaning tank with an upper opening and a spraying mechanism located above the cleaning tank. The cleaning tank has a metal mesh groove seat with an upper opening suspended inside. After the semi-finished deep groove ball bearings are placed into the metal mesh groove seat, the spraying mechanism sprays and cleans the semi-finished deep groove ball bearings inside. The wastewater after cleaning flows through the metal mesh groove seat into the bottom of the cleaning tank. The spraying mechanism includes a liquid storage tank located above the cleaning tank, and the bottom of the liquid storage tank is connected to multiple nozzles via multiple hoses. All nozzles are embedded and fixed on a long plate. A swinging mechanism is installed on the side of the liquid storage tank to swing the long plate, thereby adjusting the spraying direction of the nozzles.

[0007] Preferably, the swing mechanism includes a vertical plate fixed to one end of the liquid storage tank, and a bearing seat A is installed on the upper part of the surface of the vertical plate. A supporting bearing A is installed inside the bearing seat A. A rotating rod A is fixedly connected to the inner ring of the supporting bearing A, and a frame plate is fixedly connected to the head of the rotating rod A. The frame plate is connected to one end of the long plate. A motor for driving the rotating plate to rotate is installed on the surface of the vertical plate below the bearing seat A, and a cylindrical block located inside the frame plate is rotatably connected to the surface of the rotating plate.

[0008] Preferably, a bearing seat B is fixedly connected to the other end of the liquid storage tank, and a support bearing B is installed inside the bearing seat B. A rotating rod B is fixedly connected to the inner ring of the support bearing B, and a connecting plate is fixedly connected to the head of the rotating rod B. The connecting plate is connected to the other end of the long plate.

[0009] Preferably, a horizontal plate is fixedly connected to the back of the liquid storage tank, and an electric telescopic rod is installed at the top of the horizontal plate. A lifting plate is fixedly connected to the head of the electric telescopic rod, and the lifting plate is connected to the back of the liquid storage tank.

[0010] Preferably, both sides of the cleaning tank are fixedly connected to a through slot seat, and both sides of the top of the metal mesh slot seat are fixedly connected to a support plate, and the bottom end of the support plate is welded with a protrusion that can be inserted into the through slot seat.

[0011] Preferably, the bottom four corners of the cleaning tank are connected to a cast iron counterweight base via support rods.

[0012] Preferably, a drain pipe equipped with a valve is installed at the middle of the bottom of the cleaning tank.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model uses a swing mechanism to drive the long plate to swing, so that the spray direction of the nozzles changes dynamically with the swing of the long plate, thereby fully covering the surface of the bearing semi-finished product and complex parts such as grooves and chamfers, reducing cleaning dead corners. It can achieve all-round cleaning without increasing the number of nozzles, thus reducing costs. The wastewater generated during the cleaning process flows quickly into the bottom of the cleaning tank through the mesh of the metal mesh slot seat that is suspended relative to the cleaning tank, and quickly separates from the bearing semi-finished product to be cleaned. This avoids impurities from repeatedly adhering to the surface of the workpiece with the wastewater and causing secondary pollution, ensuring the cleaning effect and solving the problems in the background technology. 2. When the long plate is swung by the swinging mechanism, the other end of the long plate drives the rotating rod B to rotate through the connecting plate. The rotating rod B drives the inner ring of the support bearing B to rotate. The inner ring rotates along with the outer ring, providing follow-up support for the other end of the long plate. This can balance the eccentric torque generated when the long plate swings, prevent the long plate from tilting, bending or shaking, and ensure that the nozzle swing trajectory is accurate and stable. 3. This utility model is designed for metal mesh slot seats of different heights or bearing semi-finished products of different sizes. By adjusting the extension and retraction of the electric telescopic rod, the height of the spraying mechanism can be precisely controlled, so that the nozzle and the workpiece surface can maintain the optimal spraying distance.

[0016] like Figure 1-5As shown, this utility model provides a spray cleaning device for semi-finished deep groove ball bearings, including a cleaning tank 1 with an upper opening and a spraying mechanism 2 located above the cleaning tank 1. A metal mesh tray 3 with an upper opening is suspended inside the cleaning tank 1. After the semi-finished deep groove ball bearing is placed in the metal mesh tray 3, the spraying mechanism 2 sprays and cleans the semi-finished deep groove ball bearing inside. The wastewater after cleaning flows through the metal mesh tray 3 into the bottom of the cleaning tank 1. The four corners of the bottom of the cleaning tank 1 are connected to a cast iron counterweight base 11 by support rods 10. The cast iron counterweight base 11 has a large weight and can stably support the spray cleaning device. A drain pipe 12 equipped with a valve 13 is installed in the middle of the bottom of the cleaning tank 1.

[0017] The spraying mechanism 2 includes a liquid storage tank 201 located above the cleaning tank 1, and the bottom of the liquid storage tank 201 is connected to multiple nozzles 203 via multiple hoses 202. All nozzles 203 are embedded and fixed on a long plate 204. A swinging mechanism 205 is installed on the side of the liquid storage tank 201 to swing the long plate 204, thereby adjusting the spraying direction of the nozzles 203.

[0018] In use, the semi-finished deep groove ball bearing to be cleaned is placed in the suspended metal mesh tray 3 inside the cleaning tank 1. The cleaning fluid in the storage tank 201 is delivered to multiple nozzles 203 fixed on the long plate 204 through multiple hoses 202 (the storage tank 201 is connected to the cleaning fluid delivery pipe, and it is necessary to ensure that there is sufficient cleaning fluid in it to continuously provide a stable spray pressure and flow rate for the nozzles 203). The nozzles 203 spray the cleaning fluid into the semi-finished bearing in the metal mesh tray 3 for spray cleaning. At the same time, the swing mechanism 205 on the side of the storage tank 201 drives the long plate 204 to swing, so that the spray direction of the nozzles 203 dynamically changes with the swing of the long plate 204. The changes allow for comprehensive coverage of the surface, grooves, chamfers, and other complex areas of the bearing semi-finished product, reducing cleaning dead spots. This eliminates the need to increase the number of nozzles 203 to achieve all-around cleaning, thus reducing costs (the manufacturing cost of the swing mechanism 205 is far lower than the cost of adding multiple nozzles 203 and their corresponding pipes). Wastewater generated during cleaning flows quickly through the mesh of the metal mesh seat 3 into the bottom of the cleaning tank 1 (by opening the valve 13 of the drain pipe 12, wastewater is discharged from the cleaning tank 1), quickly separating from the bearing semi-finished product to be cleaned. This prevents impurities from repeatedly adhering to the workpiece surface with the wastewater, causing secondary pollution and ensuring effective cleaning.

[0019] The following is the specific structure of the metal mesh trough seat 3 suspended in the cleaning box 1: both sides of the cleaning box 1 are fixedly connected to the through groove seat 7, and both sides of the top of the metal mesh trough seat 3 are fixedly connected to the support plate 8, and the bottom end of the support plate 8 is welded with a protrusion 9 that can be inserted into the through groove seat 7.

[0020] Insert the protrusions 9 on the two support plates 8 at the top of the metal mesh trough seat 3 into the through slot seat 7 in the cleaning box 1 to limit the movement (at this time, the bottom surface of the support plate 8 is in close contact with the top surface of the through slot seat 7). This allows the metal mesh trough seat 3 to be suspended relative to the cleaning box 1 (the bottom of the metal mesh trough seat 3 is a certain distance from the bottom of the cleaning box 1). To remove the metal mesh trough seat 3 from the cleaning box 1, simply hold the two support plates 8 at the top of the metal mesh trough seat 3 and apply upward pulling force to dislodge the protrusions 9 welded to the bottom of the support plates 8 from the through slot seats 7 fixedly connected to both sides of the cleaning box 1. This allows the metal mesh trough seat 3 to be removed from the cleaning box 1.

[0021] The following is the specific structure of the swing mechanism 205: The swing mechanism 205 includes a vertical plate 2051 fixed to one end of the liquid storage tank 201, and a bearing seat A2052 is installed on the upper part of the surface of the vertical plate 2051. A support bearing A2053 is installed inside the bearing seat A2052. A rotating rod A2054 is fixedly connected to the inner ring of the support bearing A2053, and a frame plate 2055 is fixedly connected to the head of the rotating rod A2054. The frame plate 2055 is connected to one end of the long plate 204. A motor 2056 for driving the rotating plate 2057 to rotate is installed on the surface of the vertical plate 2051 below the bearing seat A2052, and a cylindrical block 2058 located inside the frame plate 2055 is rotatably connected to the surface of the rotating plate 2057.

[0022] In use, the motor 2056 is started, and the motor 2056 drives the rotating plate 2057 to rotate. The cylindrical block 2058 on the surface of the rotating plate 2057 moves in a circular motion with the rotating plate 2057. Since the cylindrical block 2058 is located inside the frame plate 2055, its circular motion can drive the frame plate 2055 to swing back and forth around the rotating rod A2054 as the axis (the rotating rod A2054 drives the inner ring of the support bearing A2053 to rotate, and its inner ring rotates along its outer ring, providing stable support for the swing). The frame plate 2055 is connected to one end of the long plate 204, which in turn drives the long plate 204 and the multiple nozzles 203 fixed on it to swing back and forth synchronously, realizing the dynamic adjustment of the spray direction of the nozzles 203, so as to fully cover the deep groove ball bearing semi-finished product in the metal mesh groove seat 3.

[0023] Furthermore, a bearing seat B206 is fixedly connected to the other end of the liquid storage tank 201, and a support bearing B207 is installed inside the bearing seat B206. A rotating rod B208 is fixedly connected to the inner ring of the support bearing B207, and a connecting plate 209 is fixedly connected to the head of the rotating rod B208. The connecting plate 209 is connected to the other end of the long plate 204. When the long plate 204 is swung by the swing mechanism 205, the other end of the long plate 204 drives the rotating rod B208 to rotate through the connecting plate 209. The rotating rod B208 drives the inner ring of the support bearing B207 to rotate. Its inner ring rotates along with its outer ring, providing follow-up support for the other end of the long plate 204. This can balance the eccentric torque generated when the long plate 204 swings, prevent the long plate 204 from tilting, bending or shaking, and ensure that the swing trajectory of the nozzle 203 is accurate and stable.

[0024] Furthermore, a horizontal plate 4 is fixedly connected to the back of the liquid storage tank 201, and an electric telescopic rod 5 is installed at the top of the horizontal plate 4. A lifting plate 6 is fixedly connected to the head of the electric telescopic rod 5, and the lifting plate 6 is connected to the back of the liquid storage tank 201. By controlling the extension and retraction of the electric telescopic rod 5, the lifting plate 6 and the liquid storage tank 201 are moved up and down, thereby adjusting the height of the spraying mechanism 2.

[0025] Before cleaning, when the metal mesh tray 3 needs to be placed, the electric telescopic rod 5 can be extended to move the lifting plate 6 and the liquid storage tank 201 upwards, thereby raising the height of the entire spraying mechanism 2 and creating sufficient operating space above the cleaning tank 1. This completely avoids the spraying mechanism 2 (especially the long plate 204, nozzle 203, and other components) from obstructing the path of the metal mesh tray 3, allowing operators to easily and smoothly place the metal mesh tray 3 containing the deep groove ball bearing semi-finished product into the cleaning tank 1 without having to painstakingly avoid the spraying components, thus improving the convenience of loading. At the same time, for metal mesh trays 3 of different height specifications or bearing semi-finished products of different sizes, the height of the spraying mechanism 2 can be precisely controlled by adjusting the extension amount of the electric telescopic rod 5, so that the nozzle 203 maintains the optimal spraying distance from the workpiece surface.

However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model.
