Abstract
Description
Technical Field
[0001] This utility model relates to the field of gear processing technology, and in particular to a burr removal device for automotive gear processing. Background Technology
[0002] Gears are crucial components in mechanical transmission, widely used in various machines and equipment, responsible for transmitting power and changing the direction of motion. The precision and surface cleanliness of gears have a direct impact on the performance of the entire mechanical system. During gear processing, especially in the cutting or milling stage, burrs are often generated on the edges or tooth surfaces of the gears. These burrs are an unavoidable byproduct of metal processing. Burrs not only reduce the precision of the gears but may also cause assembly problems and accelerate component wear. Therefore, further deep processing—that is, burr removal—is needed to improve the quality and functionality of the gears.
[0003] A search revealed that patent application number CN202421094004.6 discloses a burr removal device for gear processing. Although the device uses an automatic control system, including an electric push rod and a precise clamping mechanism, to ensure that the gear maintains the correct position and angle during the grinding process, the device mainly relies on the grinding mechanism to remove burrs. The grinding method is difficult to effectively clean burrs in the internal and inter-tooth areas of gears with complex shapes, and prolonged grinding may damage the surface precision of the gear. Utility Model Content
[0004] The main purpose of this invention is to propose a burr removal device for automotive gear processing, which aims to solve the problems of relying on grinding mechanisms to remove burrs, the difficulty of effectively cleaning burrs in the internal and inter-tooth areas of complex-shaped gears, and the potential damage to the surface precision of gears due to prolonged grinding.
[0005] To solve the above problems, this utility model proposes a burr removal device for automotive gear processing, including a bracket, a guide bucket installed at the bottom end of the bracket, a housing installed on the bracket, and a feeding mechanism mounted on the bracket.
[0006] The feeding mechanism includes a fixed plate, which is installed inside the housing. A first nozzle and a second nozzle are respectively installed on both sides of the fixed plate via fixed blocks. The first nozzle sprays low-temperature gas, and the second nozzle sprays a water-based solution containing abrasive particles. The feeding mechanism is located inside the housing and is provided with a limiting rail. The feeding mechanism is positioned by limiting the feeding component through the limiting rail.
[0007] In one embodiment, baffles are provided on both sides of the fixing block to prevent the spray from the first nozzle and the second nozzle from splashing.
[0008] In one embodiment, toothed discs are installed at both ends of the fixing plate, chains are installed on the toothed discs, and limit blocks are installed on the chains via connecting plates.
[0009] In one embodiment, the feeding assembly moves within a limiting track via a limiting block.
[0010] In one embodiment, a motor is mounted on one end of the fixing plate, and the motor is connected to the gear plate at one end of the fixing plate via a reducer.
[0011] In one embodiment, the feeding assembly includes a base plate with a groove on one side. A limit shaft is rotatably mounted on the base plate via a bearing, and a gear to be processed is rotatably mounted on the feeding assembly via the limit shaft.
[0012] In one embodiment, the groove of the feeding assembly faces the second nozzle, and the medium ejected from the second nozzle flows through the groove into the guide hopper.
[0013] In one embodiment, the first nozzle and the second nozzle are located on both sides of the gear to be processed, and both the first nozzle and the second nozzle are arranged along the tangential direction of the gear to be processed.
[0014] In one embodiment, the feeding components are equidistantly distributed on the limiting track by limiting blocks.
[0015] In one embodiment, the chain is driven by a motor-driven reducer and a toothed disc for intermittent transmission.
[0016] Beneficial effects:
[0017] The burr removal equipment for automotive gear processing provided by this utility model has the following beneficial effects:
[0018] The feeding component moves intermittently, ensuring that each gear to be processed has sufficient time to undergo burr removal, thus improving the processing effect. At the same time, it coordinates with the overall processing rhythm and reduces equipment energy consumption.
[0019] The equipment uses a first nozzle to spray low-temperature gas and a second nozzle to spray a water-based solution containing abrasive particles. The two nozzles are set along the tangential direction of the gear to be processed, which can process the gear from different angles. By utilizing the impact of the low-temperature gas and the abrasive effect of the water-based solution containing abrasive particles, the burrs on the surface of the gear are effectively removed, improving the efficiency and quality of burr removal.
[0020] The fixed block is equipped with baffles on both sides to prevent the spray from the first and second nozzles from splashing and causing pollution to the surrounding environment. It also reduces the potential harm of the spray to operators and improves the safety of the working environment.
[0021] The feeding mechanism is equipped with a limit track. The feeding components move within the limit track via limit blocks, and the feeding components are equidistantly distributed within the limit track. This enables precise positioning and stable conveying of the gears to be processed, ensuring the positional accuracy of each gear during the burr removal process, which helps improve the consistency and stability of the processing.
[0022] The motor drives the chain intermittently through the reducer and gear plate, which allows the feeding assembly to move intermittently. This design allows each gear to stay in a specific position for a sufficient amount of time to fully receive the burr removal process, thus improving the burr removal effect.
[0023] The groove of the feeding component faces the second nozzle. The medium sprayed from the second nozzle flows into the guide hopper through the groove, which facilitates the collection of media such as water-based solutions containing abrasive particles after spraying. This makes it easier for subsequent processing and recycling, helps to keep the inside of the equipment clean, and reduces the impact of media residue on the equipment.
[0024] A limit shaft is rotatably mounted on the feeding assembly via a bearing, and the gear to be processed is rotatably mounted on the feeding assembly via the limit shaft. This mounting method facilitates the loading and unloading of the gear to be processed, improves work efficiency, and also ensures the rotational flexibility of the gear during processing, which is conducive to the complete removal of burrs.

[0036] Please see Figures 1 to 4 As shown, the embodiments provided by this utility model are as follows:
[0037] Example 1
[0038] A burr removal device for automotive gear processing includes a support 2, a guide bucket 3 mounted at the bottom of the support 2, a housing 1 mounted on the support 2, and a feeding mechanism 4 mounted on the support 2. The feeding mechanism 4 includes a fixing plate 403 and is mounted inside the housing 1 via the fixing plate 403. A first nozzle 404 and a second nozzle 411 are respectively mounted on both sides of the fixing plate 403 via fixing blocks 405. The first nozzle 404 sprays low-temperature gas, and the second nozzle 411 sprays a water-based solution containing abrasive particles. The first nozzle 404 and the second nozzle 411 are located on both sides of the gear 505 to be processed, and the first nozzle 404 sprays a water-based solution containing abrasive particles. Both nozzle 404 and nozzle 411 are arranged along the tangential direction of the gear 505 to be processed. The low-temperature gas sprayed by the first nozzle 404 and the water-based solution containing abrasive particles sprayed by the second nozzle 411 can act on the gear 505 to be processed from different directions at the same time, forming a synergistic effect of mechanical grinding and thermal stress cracking, which significantly improves the efficiency and quality of burr removal. Baffles 410 are provided on both sides of the fixed block 405 to prevent the sprayed materials from the first nozzle 404 and the second nozzle 411 from splashing, effectively avoiding the sprayed materials from splashing everywhere, maintaining the cleanliness of the working environment around the equipment, and reducing cleaning costs.Meanwhile, to prevent accidental splashing of sprayed materials from injuring operators, the safety of operation is greatly improved. The feeding mechanism 4 is located inside the housing 1 and is equipped with a limiting rail 409. The feeding mechanism 4 limits the placement of the feeding component 5 through the limiting rail 409. Gear discs 406 are installed at both ends of the fixed plate 403, and a motor 401 is installed at one end of the fixed plate 403. The motor 401 and the gear disc 406 at one end of the fixed plate 403 are connected by a reducer 402. The reducer 402 can adjust the speed and torque output of the motor 401 according to the processing requirements, so that the gear disc 406 obtains a suitable speed and driving force to meet the feeding speed requirements of different processing processes, while reducing the load on the motor 401 and extending the service life of the motor 401. A chain 407 is installed on the gear disc 406. The chain 407 drives the reducer 402 and the gear disc 406 intermittently through the motor 401, so that the feeding component 5 moves intermittently, ensuring that each gear 505 to be processed has sufficient time to receive the raw material. The removal of burrs improves processing efficiency and, in conjunction with the overall processing rhythm, reduces equipment energy consumption. A limit block 412 is installed on the chain 407 via a connecting plate 408, creating a stable transmission and positioning system. The gear disc 406 and chain 407 work together to achieve efficient power transmission. The limit block 412 precisely limits the position of the feeding component 5, ensuring the stability and accuracy of the feeding process. The feeding component 5 moves within the limit track 409 via the limit block 412. The limit track 409 provides precise guidance for the movement of the feeding component 5. The limit block 412 drives the feeding component 5 to move smoothly along the predetermined path, avoiding deviation and ensuring the consistency of gear processing positions. The feeding components 5 are equidistantly distributed on the limit track 409 via the limit block 412, ensuring that each gear 505 to be processed is in the same position in the processing area, standardizing the processing process, improving product consistency and stability, and facilitating automated production.
[0039] Example 2
[0040] To improve the processing efficiency and optimize the processing quality of automotive gear deburring equipment, and to reduce equipment maintenance costs, for example, such as Figures 1 to 4As shown, this utility model also includes: a feeding assembly 5 including a base plate 504, a groove 502 on one side of the base plate 504, a limiting shaft 501 rotatably mounted on the base plate 504 via a bearing 503, and a gear 505 to be processed rotatably mounted on the feeding assembly 5 via the limiting shaft 501. The use of the bearing 503 allows the gear 505 to be processed to rotate flexibly, ensuring that all parts of the gear can be fully deburred. The design of the groove 502 and the limiting shaft 501 facilitates the installation and disassembly of the gear 505 to be processed, significantly improving work efficiency. The groove 502 of the feeding assembly 5 faces the second nozzle 411. The medium sprayed from the second nozzle 411 flows into the guide hopper 3 through the groove 502, which facilitates the centralized collection of the water-based solution containing abrasive particles sprayed from the second nozzle 411, preventing the solution from flowing everywhere, facilitating subsequent recycling and treatment of the solution, maintaining the cleanliness of the equipment interior, and reducing the corrosion of the equipment by solution residue.
[0041] Working principle:
[0042] First, the gear 505 to be processed is installed on the limiting shaft 501 of the feeding assembly 5. The feeding assembly 5 is located within the limiting track 409 of the feeding mechanism 4 and is connected to the chain 407 via the limiting block 412. The motor 401 is started, and the gear plate 406 is driven to rotate via the reducer 402. The gear plate 406 drives the chain 407 to perform intermittent transmission, so that the feeding assembly 5 moves equidistantly within the limiting track 409.
[0043] When the feeding assembly 5 moves to the processing position, the first nozzle 404 sprays low-temperature gas along the tangent of the gear 505 to be processed, and the second nozzle 411 sprays a water-based solution containing abrasive particles along the tangent of the gear 505 to be processed. Mechanical grinding and thermal stress cracking work synergistically. During this process, the water-based solution containing abrasive particles mechanically grinds the gear surface, while the low-temperature gas rapidly cools the gear surface locally, generating thermal stress. The synergistic effect of both causes micro-cracks to form at the root of the burr, improving the efficiency and effectiveness of burr removal.
[0044] The feeding assembly 5 has a groove 502. The water-based solution containing abrasive particles sprayed from the second nozzle 411 flows through the groove 502 into the guide hopper 3 for media collection. After the burrs are removed, airflow is used to blow off the residual treatment liquid on the gears, ensuring that the gear surface is clean. This completes one processing cycle. The chain 407 continues to drive intermittently, driving the next feeding assembly 5 into the processing position, and repeating the above operation.
[0045] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
