Description

Technical Field

[0001] This utility model relates to the technical field of frame spraying devices, and in particular to a rotatable reducer frame anti-rust spraying device. Background Technology

[0002] The gearbox frame is a fundamental component that secures the gearbox parts, providing support and protection for the gearbox. Gearbox frames are typically made of materials such as cast iron or steel plates, and the quality of their manufacturing directly affects the service life and performance of the gearbox. To prevent rust, an anti-rust coating is applied to the surface of the gearbox frame.

[0003] The gearbox frame is mostly painted manually, one side at a time, which easily leads to uneven painting, poor painting quality and low efficiency.

[0004] A publicly available technical solution, CN219168709U, discloses a rust-proof spraying device for a speed reducer frame. The device includes a chassis, a liquid collection assembly mounted on the chassis, a drive assembly, a positioning assembly, and a spray nozzle mounted on the liquid collection assembly. The liquid collection assembly includes a collection chamber and a support plate. The collection chamber has an opening at its upper end and is mounted on the chassis. A guide plate is coaxially aligned with the opening of the collection chamber and mounted on the collection chamber. By using the drive assembly, a motor drives the lower top plate to rotate. Because the upper top plate and the lead screw are rotatably connected via bearings, and the lower top plate is rotatably connected to the guide plate ring, the rotation of the lower top plate drives the speed reducer frame to rotate. Depending on the height of the speed reducer frame, the spray nozzle mounted on the inner wall of the fixed housing is selected to open and spray the speed reducer frame, resulting in a more uniform coating.

[0005] In actual implementation, the above technical solution uses an upper and lower top plate to clamp the reducer frame placed inside the movable housing. However, most reducer frames are annular supports with a hollow center, while the upper top plate is an inverted conical structure with fixed dimensions. If the inner diameter of the reducer frame is larger than the diameter of the upper top plate, the reducer frame will not be clamped tightly, affecting subsequent spraying. Summary of the Invention

[0006] The purpose of this utility model is to provide a rotatable reducer frame anti-rust spraying device, which can adjust the clamping mechanism according to the diameter of the reducer frame, so as to facilitate the clamping of the reducer frame and solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a rotatable reducer frame anti-rust spraying device, comprising a spraying housing, a door mechanism slidably installed on the inner wall of the spraying housing, a rotating mechanism installed inside the spraying housing, and a clamping mechanism for clamping the reducer frame provided above the rotating mechanism;

[0008] The clamping mechanism includes a clamping screw threadedly connected to the spraying housing, and an adjusting plate is mounted on the bottom of the clamping screw via a bearing. A moving block is slidably mounted on the bottom of the adjusting plate, and a support rod is fixedly installed below the moving block. A clamping block is fixedly installed at the bottom of the support rod, and a bidirectional lead screw is connected inside the moving block via a lead screw sleeve.

[0009] Preferably, a limiting groove is provided at the connection between the moving block and the adjusting plate, and the moving block slides on the adjusting plate through a bidirectional lead screw and the limiting groove.

[0010] Preferably, the rotating mechanism includes a rotating disk rotatably mounted on the bottom of the spraying housing, and a rotating rod is fixedly provided at the bottom of the rotating disk, with the power output end of a stepper motor fixedly connected to the end of the rotating rod.

[0011] Preferably, the rotating disk has several filter holes inside, and the bottom of the spraying housing has a hollow structure.

[0012] Preferably, the door mechanism includes a door body that is slidably installed inside the spraying housing. A spring is connected to one side of the door body, and an installation cavity is provided on the outside of the spring. The end of the spring is fixed to the inner wall of the spraying housing.

[0013] Preferably, a guide groove is provided at the connection between the main body of the door and the sprayed shell, and a guide slider is provided inside the guide groove.

[0014] Preferably, an iron block is fixedly disposed on the surface of the main body of the warehouse door, and a fixed magnet is disposed on the surface of the main body of the warehouse door that magnetically attracts the iron block.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Through the clamping mechanism, the moving block can slide on the limit slide groove under the action of the bidirectional screw, thereby driving the clamping block to move through the support rod, so as to adjust the position of the clamping block according to the diameter of the reducer frame, which facilitates the clamping of the reducer frame;

[0017] 2. Through the set door mechanism, the iron block on the main body of the door can be attracted to the inside of the fixed magnet, which makes it easy to fix the position of the main body of the door. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides a technical solution:

[0028] Please see Figures 1 to 5 A rotatable reducer frame anti-rust spraying device includes a spraying housing 1, a door mechanism 4 slidably installed on the inner wall of the spraying housing 1, a rotating mechanism 3 installed inside the spraying housing 1, and a clamping mechanism 2 for clamping the reducer frame is provided above the rotating mechanism 3.

[0029] The clamping mechanism 2 includes a clamping screw 201 threadedly connected to the spraying housing 1, and an adjusting plate 202 is mounted on the bottom of the clamping screw 201 via a bearing. A moving block 206 is slidably mounted on the bottom of the adjusting plate 202, and a support rod 204 is fixedly installed below the moving block 206. A clamping block 205 is fixedly installed at the bottom of the support rod 204. A bidirectional screw 203 is connected inside the moving block 206 via a screw sleeve. A limiting groove is provided at the connection between the moving block 206 and the adjusting plate 202. The moving block 206 slides on the adjusting plate 202 via the bidirectional screw 203 and the limiting groove.

[0030] By adopting the above technical solution, a spraying mechanism is also provided inside the spray housing 1. The spray nozzle faces the reducer frame and is connected to the spray pipe. Spraying can be performed on the rotating reducer frame through the spray nozzle. The distance between the two sets of clamping blocks 205 is adjusted according to the diameter of the reducer frame. Rotating the bidirectional lead screw 203 can drive the moving block 206 to slide on the limit slide groove through the lead screw sleeve. Thus, the clamping block 205 is moved through the support rod 204, and the reducer frame is placed between the two sets of clamping blocks 205 and the rotating mechanism 3. Rotating the clamping screw 201 can drive the adjusting plate 202 at the end of the clamping screw 201 to move downward, thereby clamping the reducer frame placed inside the spray housing 1.

[0031] Specifically, such as Figure 4 As shown, the rotating mechanism 3 includes a rotating disk 303 rotatably mounted on the bottom of the spraying housing 1, and a rotating rod 302 is fixedly provided on the bottom of the rotating disk 303. The end of the rotating rod 302 is fixedly connected to the power output end of the stepper motor 301. Several filter holes are opened inside the rotating disk 303, and the bottom of the spraying housing 1 has a hollow structure.

[0032] The door mechanism 4 includes a door body 401 that is slidably installed inside the spraying housing 1. A spring is connected to one side of the door body 401. An installation cavity 404 is sleeved on the outside of the spring, and the end of the spring is fixed to the inner wall of the spraying housing 1. A guide groove 405 is provided at the connection between the door body 401 and the spraying housing 1, and a guide slider 406 is provided inside the guide groove 405. An iron block 402 is fixedly provided on the surface of the door body 401, and a fixed magnet 403 that magnetically attracts the iron block 402 is provided on the surface of the door body 401.

[0033] By adopting the above technical solution, when the stepper motor 301 is started, the rotating rod 302 can be driven to rotate through the power output end of the stepper motor 301, and the rotating disk 303 can be driven to rotate at the bottom of the spraying housing 1. When the rotating disk 303 rotates, it can also drive the reducer frame to rotate. Since the adjusting plate 202 is installed at the bottom of the clamping screw 201 through the bearing, the adjusting plate 202 above the reducer frame can rotate in coordination with the rotation of the reducer frame. When the door body 401 is pulled, the spring can be compressed inward and the spring can be retracted inward to the interior of the mounting cavity 404. After the door body 401 is released, the door body 401 can be closed under the push of the spring. The door body 401 can slide on the guide slide groove 405 through the guide slider 406.

[0034] Working principle: When the main body 401 of the compartment door is pulled, the spring can be compressed inward, and the spring retracts inward into the mounting cavity 404. The distance between the two sets of clamping blocks 205 is adjusted according to the diameter of the reducer frame. Rotating the bidirectional lead screw 203 can drive the moving block 206 to slide on the limit slide groove through the lead screw sleeve, thereby driving the clamping block 205 to move through the support rod 204, placing the reducer frame between the two sets of clamping blocks 205 and the rotating mechanism 3. Rotating the clamping screw 201 can drive the adjusting plate 202 at the end of the clamping screw 201 to move downward, thereby clamping the reducer frame placed inside the spray shell 1. When the stepper motor 301 is started, the power of the stepper motor 301 can be transmitted to the reducer frame. The output drive rotating rod 302 rotates, which in turn drives the rotating disk 303 to rotate at the bottom of the spraying housing 1. When the rotating disk 303 rotates, it can also drive the reducer frame to rotate. Since the adjusting plate 202 is installed at the bottom of the clamping screw 201 through the bearing, the adjusting plate 202 above the reducer frame can rotate in coordination with the rotation of the reducer frame. The spraying housing 1 is also equipped with a spraying mechanism. The spraying nozzle faces the reducer frame and is connected to the spraying pipe. Spraying can be performed on the rotating reducer frame through the spraying nozzle. After the door body 401 is released, the door body 401 can be closed under the push of the spring. The door body 401 can slide on the guide slide groove 405 through the guide slider 406.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
