Description

Technical Field

[0001] This invention relates to the field of gear manufacturing equipment, specifically a large-scale gear heat treatment equipment. Background Technology

[0002] As the core component of heavy machinery transmission systems, large gears often operate under high loads, high torques, and frequent impacts. Therefore, they place extremely high demands on the hardness, wear resistance, and fatigue strength of the tooth surface. To improve the service life and reliability of gears, surface heat treatment, namely quenching and tempering, is usually required for their teeth, thereby significantly enhancing the mechanical properties of the gears.

[0003] Currently, the industry commonly uses high-frequency quenching machine tools for single-tooth gears to carry out heat treatment processes. These machines are usually equipped with fixtures for precise positioning and clamping of large gears, and can achieve precise indexing and rotation of large gears. The machine tool integrates an induction system that can perform high-frequency induction heating on each tooth of the gear, so that it can quickly rise to the quenching temperature. After heating, the tooth groove is quickly sprayed with water to cool it, thus completing the quenching process.

[0004] However, existing single-tooth high-frequency quenching machine tools still have significant shortcomings in practical applications. First, when faced with gears of different specifications, the inductor has difficulty adjusting the gap between itself and the tooth groove side quickly and accurately, resulting in uneven distribution of the induced magnetic field, reduced heat conduction efficiency, and affecting the uniformity and depth control of the quenched layer.

[0005] Secondly, during continuous heating, carbon deposits and other residues easily accumulate on the surface of the inductor and in the tooth grooves. Existing equipment lacks an effective online cleaning mechanism. Carbon buildup not only hinders the effective conduction of heat, leading to a decrease in energy efficiency, but may also affect the quality stability of subsequent tempering processes, ultimately restricting the overall treatment effect and service life of the gears. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a large gear heat treatment equipment, including a fixture, a vertically and horizontally movable bearing block is provided on the left side of the fixture via a track drive assembly, and a support plate is fixedly installed on the lower right side of the bearing block. The treatment equipment also includes a sensing unit that adapts to different tooth groove specifications by combining quick-release replacement and adaptive compensation, and a carbon removal unit for scraping off carbon deposits.

[0007] The sensing unit includes a movable plate that is slidably disposed on the right side of the support plate.

Two receiving plates are symmetrically arranged front to back on the lower part of the movable plate by sliding back and forth. The receiving plates are connected to the sensing blocks at the corresponding positions by means of being detachable by sliding up and down.

[0008] The carbon removal unit includes two support plates fixedly installed on the right side of the support plate and arranged above and below the sensing block. Several scraping springs are provided on the support plates through a connecting assembly. The connecting assembly adjusts the position of the sensing block through the limiting sensing block. The fixture is equipped with a scraping assembly for cleaning the sensing block.

[0009] Preferably, the movable plate is fixedly connected to the support plate by fastening screws, a helical spring is provided between the two receiving plates, and the receiving plates are made of insulating and heat-insulating material.

[0010] Preferably, the connecting assembly includes a guide plate fixedly installed on the lower right side of the support plate. The guide plate is provided with two sets of sliding members arranged symmetrically in front and behind. Each set consists of several sliding members arranged at equal intervals in the vertical direction. The sliding members are detachably connected to the corresponding scraping spring.

[0011] Preferably, the scraping springs are arranged at an angle, and the outer edge of the scraping springs on the same set of sliding members gradually expands outward from top to bottom.

[0012] Preferably, the scraping spring has a hollow structure in the middle, and carbon guiding grooves are equally spaced along the outer edge of the scraping spring. The carbon guiding grooves on the scraping springs at the same set of sliding parts are staggered left and right.

[0013] Preferably, a linkage plate is fixedly installed on the side of the sliding member away from the bearing plate in the same group, and the linkage plates at two corresponding positions at the top and bottom are connected to a limit plate by sliding and disassembling left and right. A ceramic pad is fixedly installed on the side of the limit plate close to the bearing plate.

[0014] Preferably, the limiting plate has two vertically arranged dome pillars that slide vertically inside it, and a return spring is provided between the dome pillars and the limiting plate. The linkage plate has a hemispherical groove for the dome pillars to be inserted at the corresponding positions.

[0015] Preferably, a pointed plate is slidably provided on the lower side of the bearing plate, and two symmetrically arranged blocking strips are slidably provided on the right end of the bearing plate. The blocking strips are fixedly connected to the linkage plate at the corresponding positions. The two blocking strips at the corresponding positions are slidably connected to the corresponding inclined surfaces of the pointed plate. A cylinder with a telescopic section fixedly connected to the pointed plate is fixedly installed on the support plate.

[0016] Preferably, the scraping assembly includes a U-shaped frame fixedly installed on the upper side of the fixture. Two swing plates arranged in a front-to-back manner are hinged to the left side of the longitudinal section of the U-shaped frame. Several scraping plates that slide along the thickness direction are evenly spaced along the length direction of the swing plates.

[0017] Preferably, a torsion spring is provided between the swing plate and the U-shaped frame, and a tension spring is provided between the scraper plate and the swing plate. The length of the scraper plate extending between the two swing plates gradually increases from right to left.

[0018] The beneficial effects of the present invention are as follows: First, the present invention adopts a quick-release replacement method for induction blocks to adapt to heating tooth grooves of different specifications, and uses a connecting component to drive the two induction blocks to achieve micro-distance adjustment, so that the working surface of the induction block always maintains a constant distance from the side of the tooth groove, thereby ensuring uniform distribution of the induction magnetic field, improving heat conduction efficiency, and ensuring the depth and uniformity of the quenching layer.

[0019] Second, during the heating process of the induction block, the present invention uses a scraping spring to clean the carbon deposits on the side of the tooth groove in real time, and uses a scraping component to scrape and clean the working surface of the induction block after heating, effectively maintaining the stability of the gap between the working surface and the tooth groove, further improving the heat conduction performance, and avoiding the adverse effects of carbon deposits on the subsequent tempering quality.

[0020] Third, the present invention uses multiple scraping springs on the same set of sliding parts, whose outer edges gradually expand outward from top to bottom, so as to realize the gradual increase of scraping force during the cleaning of the tooth groove. Combined with the vertically arranged multi-layer scraping springs to scrape off carbon deposits in layers, the carbon cleaning effect and adaptability are significantly improved.

[0021] Fourth, the present invention adopts a structure with a hollowed-out center and staggered carbon guide grooves on the edge of the scraping spring, which promotes the rapid removal of carbon deposits while comprehensively scraping the surface of the tooth groove, avoids carbon deposits from affecting the scraping efficiency of the scraping spring, and maintains a continuous and stable carbon removal ability.

[0032] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, they shall be performed in accordance with the techniques or conditions described in the literature in the art or in accordance with the product manual.

[0033] See Figure 1 and Figure 2 A large gear heat treatment equipment includes a fixture 1. A vertically and horizontally movable bearing block 2 is provided on the left side of the fixture 1 via a track drive assembly. A support plate 3 is fixedly installed on the lower right side of the bearing block 2. The equipment also includes a sensing unit 4 that can adapt to different gear groove specifications by combining quick-release replacement and adaptive compensation, and a carbon removal unit 5 for scraping off carbon deposits.

[0034] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The sensing unit 4 includes a movable plate 41 that is slidably disposed on the right side of the support plate 3. Two sensing blocks 42 are symmetrically arranged on the right side of the support plate 3 by means of sliding and detaching. Two receiving plates 43 are symmetrically arranged on the lower part of the movable plate 41 by sliding and detaching. The receiving plates 43 are connected to the sensing blocks 42 at the corresponding positions by means of sliding and detaching.

[0035] Continue reading Figure 1 , Figure 2 , Figure 3 and Figure 4The carbon removal unit 5 includes two support plates 51 fixedly installed on the right side of the support plate 3 and arranged above and below the sensing block 42. Several scraping springs 53 are provided on the support plate 51 through the connecting component 52. The connecting component 52 adjusts the position of the sensing block 42 through the limiting sensing block 42. The fixture 1 is provided with a scraping component 54 for cleaning the sensing block 42.

[0036] When large gears need to be quenched, the operator first uses a hoisting device to move the large gears onto the fixture 1 and uses the fixture 1 to center and clamp the gears. Then, according to the specifications of the gear tooth grooves, two sensing blocks 42 corresponding to the side profile of the tooth grooves are selected. The operator then slides the sensing blocks 42 along the front-back direction to the right side of the support plate 3, so that the horizontal height of the sensing blocks 42 is locked by the support plate 3.

[0037] Then the operator manually moves the moving plate 41 downwards. The moving plate 41 drives the two receiving plates 43 to slide and connect to the corresponding sensing blocks 42 respectively, so that the sensing blocks 42 and the receiving plates 43 move back and forth synchronously. Then the operator connects the high-frequency power supply to the two sensing blocks 42, so that the sensing blocks 42 can perform induction heating on the tooth groove, thereby completing the quick installation of the sensing blocks 42.

[0038] Subsequently, the track drive assembly drives the induction block 42 to move to the lower side of the corresponding gear tooth groove via the carrier block 2 and the support plate 3. At the same time, the support plate 3 drives the upper scraping spring 53 to extend into the tooth groove via the carrier plate 51 and the connecting component 52. Then, the outer side of the scraping spring 53 abuts against the side of the tooth groove via the connecting component 52. At the same time, the connecting component 52 limits the induction block 42, and the carrier plate 51 pushes the induction block 42 outward, so that the distance between the working surface of the induction block 42 and the side of the tooth groove is constant, ensuring the uniformity of induction heating.

[0039] Then, the scraping spring 53 and the sensing block 42 are moved upward by the track drive assembly, and the sensing block 42 is energized. The scraping spring 53 located on the upper part of the sensing block 42 pre-cleans the side of the tooth groove to ensure that the distance between the working surface of the sensing block 42 and the side of the tooth groove is constant. Then, the sensing block 42 moves into the tooth groove, so that the sensing block 42 heats the corresponding position of the tooth groove to the quenching temperature.

[0040] It should be noted that a water pipe is fixedly installed on the support plate 3 between the induction block 42 and the lower scraping spring 53. The water pipe is connected to the coolant supply device. While the induction block 42 moves upward and heats up, the water pipe sprays coolant into the tooth groove, thereby rapidly cooling the part of the tooth groove heated to the quenching temperature, thus completing the quenching. Then, the support plate 3 drives the lower scraping spring 53 to contact the side of the tooth groove, so that the lower scraping spring 53 scrapes off the carbon deposits generated on the side of the tooth groove, ensuring the heating efficiency of the induction block 42 on the tooth groove when the tooth groove is tempered later.

[0041] When the scraping spring 53 at the lower part moves completely to the upper part of the gear, the sensing block 42 moves up to the position of the corresponding scraping component 54. Then, the sensing block 42 is moved to the right by the track drive assembly and into the scraping component 54, so that the scraping component 54 scrapes off the carbon deposits on the working surface of the sensing block 42. Then, the gear is rotated by a certain angle by the fixture 1. Then, the sensing block 42 is moved to the lower part of the tooth groove again. The above steps are repeated until all tooth grooves of the gear are quenched.

[0042] To enable the scraping spring 53 to scrape grooves of different specifications, the present invention designs the following structure: (See reference) Figure 2 , Figure 3 and Figure 5 The connecting component 52 includes a guide plate 521 fixedly installed on the lower right side of the support plate 51. The guide plate 521 is provided with two sets of sliding members 522 arranged symmetrically in front and behind. Each set consists of several sliding members 522 arranged at equal intervals in the vertical direction. The sliding members 522 are detachably connected to the corresponding scraping spring 53. The sliding members 522 in the same set are fixedly connected together.

[0043] See Figure 3 , Figure 5 and Figure 6 A linkage plate 523 is fixedly installed on the side of the sliding member 522 away from the bearing plate 51. Two symmetrically arranged blocking strips 512 are slidably arranged on the right end of the bearing plate 51. The blocking strips 512 are fixedly connected to the linkage plate 523 at the corresponding positions.

[0044] When the two scraping springs 53 located at the uppermost side of the upper part of the sensing block 42 extend into the tooth groove, the two upper blocking strips 512 are also located inside the tooth groove. Then, the two blocking strips 512 move synchronously in a direction away from each other, so that the two upper blocking strips 512 abut against the two sides of the tooth groove respectively. The blocking strips 512 drive the corresponding sliding members 522 to move synchronously through the linkage plate 523, so that the sliding members 522 drive the two scraping springs 53 located at the uppermost side of the upper part of the sensing block 42 to press against the sides of the tooth groove.

[0045] It should be noted that at this time, the reaction force of the tooth groove on the two scraping springs 53 located on the uppermost side of the upper part of the sensing block 42 pushes the two scraping springs 53 located on the uppermost side of the upper part of the sensing block 42 to deform slightly, so that the scraping springs 53 press against the side of the tooth groove through their own elasticity, ensuring the contact force between the scraping springs 53 and the tooth groove, thereby ensuring the scraping effect on the side of the tooth groove.

[0046] It should also be noted that the left side of the slider 522 is block-shaped and the right side is rod-shaped. The rod-shaped structure of the slider 522 has a groove for the scraping spring 53 to be inserted. When the scraping spring 53 is inserted into the rod-shaped structure of the slider 522, the scraping spring 53 is fixedly connected to the slider 522 by a pin, which facilitates the replacement of the scraping spring 53. The pin is not shown in the figure.

[0047] In order to abut the blocking strip 512 against the side of the tooth groove, the present invention has designed the following structure: See Figure 3 , Figure 5 and Figure 6 A pointed plate 511 is slidably provided on the lower side of the bearing plate 51. The two corresponding blocking strips 512 at the front and rear are slidably connected to the corresponding inclined surfaces of the pointed plate 511. A cylinder 513 with a telescopic section and a fixed connection to the pointed plate 511 is fixedly installed on the support plate 3.

[0048] When it is necessary to move the blocking strip 512 closer to the side of the tooth groove, the extension sections of the upper and lower cylinders 513 extend at the same time, so that the cylinders 513 push the corresponding pointed plate 511 to the right, and the pointed plate 511 pushes the blocking strip 512 to the front and rear sides, so that the upper blocking strip 512 first abuts against the side of the tooth groove.

[0049] To ensure the fine-tuning accuracy of the two sensing blocks 42 and maintain a constant distance between the working surface of the sensing block 42 and the side surface of the tooth groove, the present invention designs the following structure: (See reference) Figure 3 and Figure 4 The movable plate 41 is fixedly connected to the support plate 3 by fastening screws. A helical spring is provided between the two support plates 43. The support plates 43 are made of insulating and heat-insulating material.

[0050] See Figure 3 and Figure 7 The two corresponding linkage plates 523 are connected to the limit plate 524 by sliding and disassembling left and right. A ceramic pad is fixedly installed on the side of the limit plate 524 near the bearing plate 51.

[0051] When the two sensing blocks 42 are connected to the corresponding receiving plate 43, the operator manually squeezes the two sensing blocks 42 so that the two sensing blocks 42 are located between the front and rear linkage plates 523. Then the operator holds the limiting plate 524 and moves it laterally while simultaneously sliding it between the upper and lower corresponding linkage plates 523, so that the upper and lower linkage plates 523 can move back and forth synchronously through the limiting plate 524, and at the same time, the two sensing blocks 42 are located between the two limiting plates 524.

[0052] Then the external force on the two sensing blocks 42 is removed, so that the helical spring pushes the two supporting plates 43 away from each other through its own elasticity. The supporting plates 43 drive the sensing blocks 42 to move against the ceramic pad of the limiting plate 524, so that the sensing blocks 42 move back and forth synchronously with the linkage plate 523 and the blocking bar 512. Then, when the blocking bar 512 abuts against the side of the tooth groove, the sensing blocks 42 move to a position where there is a certain gap between its working surface and the side of the tooth groove. And through the push of the helical spring, the gap between the working surface of the sensing blocks 42 and the side of the tooth groove is kept constant.

[0053] It should be noted that when the sensing block 42 moves to the middle of the tooth groove, the two upper blocking bars 512 and the two lower blocking bars 512 can simultaneously contact the side of the tooth groove. This allows the two upper blocking bars 512 to continue to limit the sensing block 42 when it moves to the upper part of the gear, thereby ensuring that the gap between the working surface of the sensing block 42 and the side of the tooth groove remains constant.

[0054] To ensure a stable connection between the limiting plate 524 and the linkage plate 523, and to maintain quick disassembly of the limiting plate 524 and the linkage plate 523, the present invention designs the following structure: (See attached diagram) Figure 7 The limiting plate 524 has two vertically arranged dome pillars 525 that slide up and down inside. A return spring is provided between the dome pillars 525 and the limiting plate 524. The linkage plate 523 has a hemispherical groove for the dome pillars 525 to be inserted at the position corresponding to the dome pillars 525.

[0055] When the limiting plate 524 slides onto the linkage plate 523, the dome structure of the dome pillar 525 on the limiting plate 524 contacts the edge of the linkage plate 523, causing the edge of the linkage plate 523 to push the dome pillar 525 into the limiting plate 524 and compress the corresponding return spring. When the limiting plate 524 is fully connected to the linkage plate 523, the dome pillar 525 moves and is pushed into the corresponding hemispherical groove by the return spring, thereby locking the limiting plate 524 and the linkage plate 523 to a certain extent.

[0056] To improve the cleaning effect of the scraping spring 53 on the side of the tooth groove, the present invention designs the following structure: (See reference) Figure 3 and Figure 5The scraping spring 53 is arranged at an angle. The outer edge of the scraping spring 53 on the same set of sliding members 522 gradually expands outward from top to bottom. The middle part of the scraping spring 53 has a hollow structure. The outer edge of the scraping spring 53 is provided with carbon guide grooves at equal intervals along its edge trajectory. The carbon guide grooves on the scraping spring 53 on the same set of sliding members 522 are arranged in a staggered manner.

[0057] When the scraping spring 53 moves upward, the scraping springs 53 on the same guide plate 521 contact the tooth groove side sequentially from top to bottom. As the outer edge of the scraping springs 53 on the same set of sliding members 522 gradually expands outward from top to bottom, the tooth groove side pushes the scraping springs 53 on the same guide plate 521 to gradually increase the deformation from top to bottom through the reaction force. Therefore, the scraping springs 53 on the same set of sliding members 522 can gradually increase the scraping force to clean the tooth groove side. Combined with the vertically arranged multi-layer scraping springs 53, the carbon deposits on the tooth groove are scraped layer by layer, which significantly improves the carbon cleaning effect. Moreover, due to the elasticity of the scraping springs 53 themselves, they can also adapt to the tooth sides with different shapes and contours, improving adaptability and reducing costs.

[0058] When the scraping spring 53 scrapes the tooth side, the carbon guide grooves arranged in a staggered manner on the left and right sides can not only make the scraping spring 53 completely cover the tooth side, but also promote the rapid removal of carbon deposits, avoid carbon deposits from remaining and affecting the scraping efficiency of the scraping spring 53, and maintain a continuous and stable carbon removal ability.

[0059] To remove carbon deposits on the working surface of the sensing block 42 and ensure uniform heat conduction to each tooth groove, the present invention designs the following structure: (See attached diagram) Figure 1 , Figure 2 and Figure 8 The scraping assembly 54 includes a U-shaped frame 541 fixedly installed on the upper side of the fixture 1. Two swing plates 542 arranged in a front-to-back manner are hinged to the left side of the longitudinal section of the U-shaped frame 541. Several scraping plates 543 that slide along the thickness direction are equally spaced on the swing plates 542 along their length direction.

[0060] See Figure 2 and Figure 8 A torsion spring is provided between the swing plate 542 and the U-shaped frame 541, and a tension spring is provided between the scraper plate 543 and the swing plate 542. The length of the scraper plate 543 extending between the two swing plates 542 gradually increases from right to left.

[0061] In the initial state, the two swing plates 542 have a V-shaped structure with the opening facing left. When the sensing block 42 moves up to the position of the corresponding swing plate 542, the sensing block 42 moves to the right, so that the sensing block 42 is inserted between the swing plates 542, thereby making the working surface of the sensing block 42 contact with the scraper plate 543 and move relative to it, so that the scraper plate 543 scrapes off the carbon deposits on the working surface of the sensing block 42.

[0062] It should be noted that by changing the angle of the swing plate 542 and the sensor block 42 pushing the scraper 543 to move along the thickness of the swing plate 542, the scraper 543 can adapt to sensor blocks 42 of different shapes. While ensuring the cleaning effect, the swing plate 542 and scraper 543 do not need to be replaced when replacing the sensor block 42, which reduces costs and ensures the convenience of operation.

[0063] It is particularly important to emphasize that the scraping spring 53 added in this invention can be formed in one step using a punch press. It is made of elastic thin sheet material, which is inexpensive, easy to manufacture, and efficient. Although it slightly increases the cost compared to existing quenching equipment, the real-time cleaning of the tooth groove by the scraping spring 53 allows for seamless connection between the quenching and tempering processes, greatly increasing the efficiency of heat treatment. The benefits obtained far outweigh the cost of the scraping spring 53. Furthermore, the elasticity of the scraping spring 53 itself can adapt to a certain range of tooth groove specifications and its own wear, making the scraping spring 53 highly adaptable and with a long service life, further increasing its benefits.
