Abstract
Description
Technical Field
[0001] This utility model relates to the field of gear rust prevention processing technology, specifically a gear rust prevention processing device. Background Technology
[0002] Currently, a gear is a mechanical component, commonly used to transmit power and motion. It consists of two or more toothed teeth and is widely used in various equipment and machines, such as automobiles, airplanes, and machine tools. The working principle of a gear is based on friction to transmit power. When two gears mesh, their tooth profiles come into contact with each other, generating friction, thereby transmitting power. By changing the number of teeth and the module, the speed and torque of the gear can be adjusted to meet the requirements of different mechanical systems.
[0003] In order to improve the service life of gears, rust prevention treatment is often performed on gears in the market. Phosphating is a conventional rust prevention process for gears. The metal is immersed in a heated phosphate solution for chemical treatment, so that a phosphate protective film is formed on the metal surface. The film after phosphate treatment has good rust prevention and wear resistance and is often used for the treatment of sliding parts.
[0004] However, when immersing gears in a heated phosphate solution, it is difficult to ensure that the gear surface can fully react with the phosphate solution, resulting in the formation of a phosphate protective film that cannot completely cover the gear surface. Therefore, a new technical solution needs to be designed to solve this problem, which can uniformly heat the gears and allow them to fully react with the phosphate solution, thereby improving the phosphate treatment of the gears. Utility Model Content
[0005] The purpose of this invention is to provide a gear anti-rust processing device, which solves the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a gear anti-rust processing device, including a workbench, a through groove in the middle of the workbench, fixed seats fixedly installed on both sides of the top of the workbench, and a clamping and rotating mechanism installed on both sets of fixed seats;
[0007] The clamping and rotating mechanism includes a second electric push rod fixedly installed in the middle of the side walls of both sets of fixed seats, an L-shaped frame fixedly installed at the other end of both sets of second electric push rods, a support gear rotatably installed inside both sets of L-shaped frames, and a motor fixedly installed on the top of one side of the L-shaped frame.
[0008] As an optional solution to the technical solution of this application, the motor drive output end is connected to the transmission shaft, and the other end of the transmission shaft is fixedly installed on the central shaft of the support gear located on one side, with the two sets of support gears corresponding to each other.
[0009] As an optional solution to the technical solution of this application, a soaking tank is fixedly installed at the bottom of the workbench, and a discharge port is opened at the bottom of the soaking tank. The soaking tank is filled with a phosphate solution, which can be used to prevent rust from forming on the processed gears.
[0010] As an optional solution to the technical solution of this application, a third electric push rod is fixedly installed at the bottom of the soaking tank, and a boss is fixedly installed at the other end of the third electric push rod. The boss corresponds to two sets of support gears and can support the processed gears.
[0011] As an optional solution to the technical solution of this application, a bracket is fixedly installed on the top of the worktable, a first electric push rod is fixedly installed at the middle of the top of the bracket, and a heating ring is fixedly installed at the other end of the first electric push rod. The heating ring corresponds to the boss and can heat the processed gear.
[0012] As an optional solution to the technical solution of this application, the workbench is provided with limit grooves on both sides of the top, and limit sliders are slidably installed in both sets of limit grooves. The two sets of limit sliders are fixedly installed to the bottom of the two sets of L-shaped frames, which can limit the L-shaped frames.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. The technical solution of this application drives two sets of second electric push rods inside the clamping and rotating mechanism to push two sets of L-shaped frames to move inward synchronously. After the support gears inside the two sets of L-shaped frames are engaged with the processing gear, the motor located on the top of one L-shaped frame is driven to make the processing gear rotate under stable clamping. In conjunction with the first electric push rod on the bracket, the heating ring is pushed to fit against the processing gear. This allows the processing gear to be heated evenly before oil immersion rust prevention treatment, further improving the hardenability of the processing gear.
[0015] 2. The technical solution of this application uses two sets of limiting slides to slide in each of the two sets of limiting slides, and the two sets of limiting slides are fixedly installed at the bottom of the two sets of L-shaped frames respectively. When the operator drives the second electric push rod to push the two sets of L-shaped frames to move inward synchronously, the limiting slides opened on both sides of the top of the worktable can efficiently limit the two sets of L-shaped frames, ensuring that the two sets of L-shaped frames keep moving horizontally when pushed by the second electric push rod and mesh with the gears machined on the boss.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a gear anti-rust processing device, including a workbench 1, a through groove 11 in the middle of the workbench 1, and fixed seats 2 fixedly installed on both sides of the top of the workbench 1, and a clamping and rotating mechanism installed on both sets of fixed seats 2.
[0022] The clamping and rotating mechanism includes a second electric push rod 21 fixedly installed in the middle of the side walls of both sets of fixed seats 2, an L-shaped frame 22 fixedly installed at the other end of both sets of second electric push rods 21, a support gear 23 rotatably installed inside both sets of L-shaped frames 22, and a motor 24 fixedly installed on the top of one side of the L-shaped frame 22. The drive output end of the motor 24 is connected to the transmission shaft, and the other end of the transmission shaft is fixedly installed to the central shaft of the support gear 23 on one side. The two sets of support gears 23 correspond to each other.
[0023] In this technical solution, by driving the two sets of second electric push rods 21 inside the clamping and rotating mechanism, the two sets of L-shaped frames 22 are pushed to move inward synchronously. After the support gears 23 inside the two sets of L-shaped frames 22 are engaged with the processing gear, the motor 24 located on the top of one side of the L-shaped frame 22 is driven to make the processing gear rotate under stable clamping. In conjunction with the first electric push rod 13 on the bracket 12, the heating ring 14 is pushed to fit against the processing gear. This allows the processing gear to be heated evenly before oil immersion rust prevention treatment, further improving the hardenability of the processing gear.
[0024] In some technical solutions, limit slide grooves 25 are provided on both sides of the top of the workbench 1. Limit sliders are slidably installed in both sets of limit slide grooves 25. The two sets of limit sliders are fixedly installed at the bottom of the two sets of L-shaped frames 22 respectively, which can limit the L-shaped frames 22.
[0025] In this technical solution, when the operator drives the second electric push rod 21 to push the two sets of L-shaped frames 22 to move inward synchronously, the limiting slide grooves 25 opened on both sides of the top of the worktable 1 can efficiently limit the two sets of L-shaped frames 22, ensuring that the two sets of L-shaped frames 22 keep moving horizontally when pushed by the second electric push rod 21 and mesh with the gears machined on the boss 32.
[0026] In some technical solutions, a bracket 12 is fixedly installed on the top of the workbench 1, a first electric push rod 13 is fixedly installed at the middle of the top of the bracket 12, and a heating ring 14 is fixedly installed at the other end of the first electric push rod 13. The heating ring 14 corresponds to the boss 32 and can heat the processed gear.
[0027] In this technical solution, the heating ring 14 can be pushed to fit against the processing gear by the first electric push rod 13 on the drive bracket 12, so that the processing gear can be heated evenly.
[0028] In some technical solutions, a third electric push rod 31 is fixedly installed at the bottom of the soaking tank 3, and a boss 32 is fixedly installed at the other end of the third electric push rod 31. The boss 32 corresponds to two sets of support gears 23 and can support the processed gears.
[0029] In this technical solution, the third electric push rod 31 is driven to push the boss 32, which extends out of the through groove 11 of the worktable 1. The boss 32, together with the protrusion in the middle of the boss 32, can support the gear to be processed.
[0030] In some technical solutions, a soaking tank 3 is fixedly installed at the bottom of the workbench 1. The bottom of the soaking tank 3 has a discharge port. The soaking tank 3 contains a phosphate solution, which can be used to prevent rust on the processed gears.
[0031] In this technical solution, the third electric push rod 31 is driven to push the boss 32 downward, which can push the machined gear on the boss 32 into the immersion tank 3, so that the high-temperature machined gear and the phosphate solution inside the immersion tank 3 can be treated with rust prevention.
[0032] When using a gear anti-rust processing device, it should be noted that this utility model is a gear anti-rust processing device, and each component is a general standard part or a part known to those skilled in the art. Its structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
[0033] In use, the third electric push rod 31 is first driven to push the boss 32, causing the boss 32 to extend from the through slot 11 in the worktable 1. The boss 32, in conjunction with the protruding rod in the middle, supports the gear to be processed. Simultaneously, two sets of second electric push rods 21 inside the clamping and rotating mechanism drive two sets of L-shaped frames 22 to move inward synchronously. After the support gears 23 inside both sets of L-shaped frames 22 are engaged with the processed gear, the motor 24 located at the top of one L-shaped frame 22 is driven, causing the processed gear to rotate under stable clamping. This, combined with the first electric push rod 13 on the bracket 12, pushes the heating ring 14 to engage with the processed gear. This ensures that the processed gear is evenly heated before oil immersion for rust prevention, further improving... The hardenability of the processed gears is improved by the sliding installation of limit sliders in two sets of limit grooves 25. The two sets of limit sliders are fixedly installed at the bottom of the two sets of L-shaped frames 22. When the operator drives the second electric push rod 21 to push the two sets of L-shaped frames 22 to move inward synchronously, the limit grooves 25 on both sides of the top of the worktable 1 can efficiently limit the two sets of L-shaped frames 22, ensuring that the two sets of L-shaped frames 22 keep moving horizontally when pushed by the second electric push rod 21 and mesh with the processed gear on the boss 32. Finally, the third electric push rod 31 is driven to push the boss 32 down, which can push the processed gear on the boss 32 into the soaking tank 3, so that the high-temperature processed gear can be rust-proofed by the phosphate solution inside the soaking tank 3.
