Description
Technical Field
[0001] This utility model relates to the technical field of bearing parts spraying equipment, specifically to a bearing parts anti-rust spraying device. Background Technology
[0002] The composition of bearing components varies depending on the type and application, but the core components usually include: inner ring, outer ring, rolling elements, cage, seals, dust cover, retaining ring, etc.
[0003] In related technologies, in order to prevent collisions between rolling elements, a cage is installed on the rolling elements to fix the spacing between them, prevent collisions, and guide them to be evenly distributed. After the bearing cage is manufactured, in order to improve its service life, most of them will be coated with anti-corrosion paint, which requires the use of bearing parts coating equipment.
[0004] Most existing bearing cage coating devices employ a semi-automatic coating process, requiring human-machine collaboration to coat the cage. This involves installing a rotary motor inside the coating cabinet, mounting multiple hanging rods on the motor's rotating shaft, fixing hooks to these rods, and manually hanging the cage onto the hooks. The coating is then applied via a coating device (such as a metering pump with nozzles) located on the side wall of the coating cabinet. However, most of these hanging rods are welded to the surface of the rotating shaft, making maintenance or replacement inconvenient. This requires complete disassembly of the rotating shaft or the entire coating cabinet, and it's difficult to clean or replace individual hanging rods. To address these issues, a bearing parts anti-rust coating device is proposed. Utility Model Content
[0005] In view of this, the present invention provides a rust-proof spraying device for bearing parts. The present invention separates the hook from the hanging rod by separating the second external thread from the second screw hole, and then separates the hanging rod from the hook from the rotating shaft by separating the first external thread from the first screw hole. This makes the hanging rod easier to disassemble and more practical, facilitates the maintenance and repair of the hanging rod, and also facilitates the cleaning of the hanging rod.
[0006] To solve the above-mentioned technical problems, this utility model provides a rust-proof spraying device for bearing parts, including a rotary motor installed at the bottom of the spraying cabinet, a spraying device installed on the side wall of the spraying cabinet, a rotary shaft connected to the rotary motor, multiple hanging rods installed on the rotary shaft, multiple positioning blocks installed on the surface of the rotary shaft, a first screw hole provided in the center of each of the four sides of each positioning block, a first external thread adapted to the first screw hole at one end of each hanging rod, multiple connecting blocks provided at the bottom of each hanging rod, a second screw hole provided at the bottom of each connecting block, a support rod provided at the bottom of each second screw hole, a hook welded to the bottom of each support rod, and a second external thread provided at the top of each support rod, the second external thread being adapted to the second screw hole.
[0007] A sealing plate is fixedly installed on the top of the rotary motor. The sealing plate is used to seal the top of the rotary motor to prevent the sprayed material from entering the rotary motor. The sealing plate is centered and adapted to the rotary shaft seal. An overflow plate is installed on the top of the sealing plate. The overflow plate is used to open an overflow channel. The overflow plate is centered and adapted to the rotary shaft seal.
[0008] Several overflow channels are provided on the upper surface of the overflow plate. The overflow channels are used to allow the spraying material to flow into the collection chamber. The water outlet of the overflow channel passes through the rear wall of the spraying cabinet, and the overall slope of the overflow channel is inclined towards its water outlet.
[0009] A collection chamber is installed at the bottom of the rear wall of the spray booth. The collection chamber is used to collect the liquid paint dripping from the spray booth into the guide hopper. The water outlet of the overflow channel is connected to the collection chamber. The bottom of the collection chamber is connected to the guide hopper, which is an inverted trapezoidal shape. The guide hopper is used to guide the liquid paint in the collection chamber to the drain pipe.
[0010] The bottom of the guide bucket is connected to multiple drain nozzles, which are used to guide the liquid paint in the guide bucket to the collection box. The bottom of the multiple drain nozzles is connected to a collection box, which is used to collect the spraying waste. The collection box is movable, and the liquid outlet end of the drain nozzle is at the same height as the liquid inlet end of the collection box.
[0011] A base is provided at the top of the rotating shaft. The base is used to fix the top of the rotating shaft, thereby strengthening the connection between the rotating shaft and the spray booth. The base is connected to the top of the inside of the spray booth.
[0012] The top of the spray booth is connected to multiple ventilation pipes, which connect the spray booth to the fans. The ventilation pipes are arranged in a circle around the rotating axis. Each ventilation pipe is connected to a fan at the top, which supplies cold air to the spray booth. Each fan is mounted on a bracket at the top, which is used to install the fan and also to connect and fix the fan to the top of the spray booth. Each bracket is connected to the outer top wall of the spray booth.
[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:
[0014] 1. By rotating the support rod, the second external thread is separated from the second screw hole, thereby separating the hook fixed on the support rod from the hanging rod. Then, by rotating the hanging rod, the first external thread is separated from the first screw hole, thereby separating the hanging rod from the positioning block, and thus separating the hanging rod, hook, and rotating shaft. This facilitates the disassembly and installation of the hanging rod and hook, making it convenient to use, and making it easier to maintain and repair the hanging rod, as well as to clean the hanging rod.
[0015] 2. The manifold is used to collect the liquid paint dripping from the spray booth into the guide bucket. The guide bucket is used to guide the liquid paint in the manifold into the drain pipe. The drain nozzle is used to guide the liquid paint in the guide bucket into the collection box. The collection box is used to collect the used spraying waste, preventing waste paint from being wasted and facilitating subsequent cleaning of the inside of the spray booth.
[0016] 3. The ventilation duct is used to connect the spray booth to the fan. The fan supplies cold air to the inside of the spray booth, which in turn blows cold air onto the retaining racks mounted inside the spray booth, extending their leveling time and ensuring coverage of dead corners.
