DETAILED DESCRIPTION

[0032] The embodiments of the present application are described in detail below. The embodiments described below are exemplary only, and are not intended to be limiting of the present application. Unless otherwise indicated, technical or conditions not specified in the embodiments are performed according to the techniques or conditions described in the literature in the art or according to the product instructions.

[0033] Referring to Figure 1 and Figure 2 , a large gear heat treatment equipment includes a clamp tool 1, a bearing block 2 vertically and horizontally movable is arranged on the left side of the clamp tool 1 through a track driving assembly, a support plate 3 is fixedly installed on the right side of the bearing block 2, the treatment equipment further includes an induction unit 4 adapted to different specifications of gear grooves through a combination of quick release replacement and self-adaptive compensation, and a carbon removal unit 5 for scraping off accumulated carbon.

[0034] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the induction unit 4 includes a moving plate 41 slidingly arranged on the right side of the support plate 3, two induction blocks 42 symmetrically arranged in front and back are arranged on the right side of the support plate 3 through a detachable way of forward and backward sliding, two bearing plates 43 symmetrically arranged in front and back are slidingly arranged on the lower part of the moving plate 41, and the bearing plates 43 are connected with the corresponding induction blocks 42 through a detachable way of upward and downward sliding.

[0035] Continuing to refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, except carbon unit 5 includes two bearing plates 51 fixedly installed on the right side of the support plate 3 and arranged above and below the induction block 42, and the bearing plate 51 is provided with a plurality of scraping springs 53 through a connecting assembly 52, and the connecting assembly 52 adjusts the position of the induction block 42 through the limiting induction block 42, and the fixture tool 1 is provided with a scraping assembly 54 for cleaning the induction block 42.

[0036] When the large gear needs to be quenched, first of all, the operator carries the large gear to the fixture tool 1 through the lifting equipment, and then clamps and centers the gear through the fixture tool 1, and then selects two induction blocks 42 corresponding to the profile of the gear tooth groove according to the specification of the gear tooth groove, and then the operator slides and connects the induction block 42 on the right side of the support plate 3 in the front and back direction, so that the horizontal height of the induction block 42 is locked by the support plate 3.

[0037] Then the operator manually moves the moving plate 41 downward, and the two bearing plates 43 are respectively slidably connected to the corresponding induction block 42, so that the induction block 42 moves synchronously with the bearing plate 43, and then the operator connects the high-frequency power supply to the two induction blocks 42, so that the induction block 42 can inductively heat the gear tooth groove, thereby completing the quick installation of the induction block 42.

[0038] Then the track driving assembly moves the induction block 42 to the lower side of the corresponding gear tooth groove through the bearing block 2 and the support plate 3, and at the same time, the support plate 3 drives the scraping spring 53 located at the upper part to extend into the tooth groove through the bearing plate 51 and the connecting assembly 52, and then the outer side of the scraping spring 53 is abutted on the side surface of the tooth groove through the connecting assembly 52, and at the same time, the connecting assembly 52 limits the induction block 42, and the bearing plate 51 pushes the induction block 42 outward, so that the working surface of the induction block 42 is constant distance from the side surface of the tooth groove, thereby ensuring the uniformity of the induction heating.

[0039] Then the track driving assembly moves the scraping spring 53 and the induction block 42 upward, and the induction block 42 is energized, the scraping spring 53 located at the upper part of the induction block 42 pre-cleans the side surface of the tooth groove, and the distance between the working surface of the induction block 42 and the side surface of the tooth groove is constant, and then the induction block 42 moves to the inside of the tooth groove, so that the induction block 42 heats the corresponding position of the tooth groove to the quenching temperature.

[0040] It needs to be explained that the water pipe is fixedly installed on the support plate 3 between the induction block 42 and the lower scraping elastic sheet 53, and the water pipe is connected with the cooling liquid supply device. When the induction block 42 moves and heats at the same time, the water pipe sprays the cooling liquid into the gear slot, so that the part heated to the quenching temperature in the gear slot is rapidly cooled, thereby completing quenching, and then the support plate 3 drives the lower scraping elastic sheet 53 to contact the side surface of the gear slot, so that the lower scraping elastic sheet 53 scrapes the carbon deposited on the side surface of the gear slot, ensuring the heating efficiency of the induction block 42 on the gear slot during subsequent tempering of the gear slot.

[0041] When the lower scraping elastic sheet 53 completely moves to the upper part of the gear, the induction block 42 moves to the position corresponding to the scraping assembly 54, and then the induction block 42 is horizontally moved to the inside of the scraping assembly 54 by the track driving assembly, so that the scraping assembly 54 scrapes the carbon on the working surface of the induction block 42, and then the gear is rotated by a certain angle by the clamp tool 1, and then the induction block 42 is moved to the lower part of the gear slot again, and the above steps are repeated until all the gear slots of the gear are quenched.

[0042] In order to enable the scraping elastic sheet 53 to scrape different specifications of gear slots, the present application designs the following structure: referring to Figure 2 、 Figure 3 and Figure 5 , the connecting assembly 52 comprises a guide plate 521 fixedly installed on the lower side of the right end of the bearing plate 51, and the guide plate 521 is provided with two groups of sliding members 522 arranged symmetrically in front and back, each group is composed of a plurality of sliding members 522 arranged at equal intervals in the vertical direction, the sliding members 522 are connected with the corresponding scraping elastic sheet 53 in a detachable manner, and the sliding members 522 in the same group are fixedly connected together.

[0043] Referring to Figure 3 、 Figure 5 and Figure 6 , the same group of sliding members 522 are jointly fixedly installed with a linkage plate 523 away from the side of the bearing plate 51, and the right end of the bearing plate 51 is provided with two front and back symmetrically arranged blocking strips 512 which are slidingly arranged in front and back, and the blocking strips 512 are fixedly connected with the linkage plate 523 at the corresponding position.

[0044] When the two scraping elastic sheets 53 located at the uppermost side of the upper part of the induction block 42 extend into the inside of the gear slot, the two blocking strips 512 in the upper part are also located in the inside of the gear slot, and then the two blocking strips 512 are synchronously moved in the direction away from each other, so that the two blocking strips 512 in the upper part are respectively abutted on the two side surfaces of the gear slot, and the blocking strips 512 drive the sliding members 522 at the corresponding position to synchronously move through the linkage plate 523, so that the sliding members 522 drive the two scraping elastic sheets 53 located at the uppermost side of the upper part of the induction block 42 to abut on the side surfaces of the gear slot.

[0045] Need to explain, at this time, the tooth groove on the uppermost side of the two scraping pieces 53 on the induction block 42, push the two scraping pieces 53 on the uppermost side of the induction block 42 slightly deformed, so that the scraping piece 53 through its own elastic resistance in the side of the tooth groove, ensure the contact degree of scraping piece 53 and tooth groove, in turn ensure the scraping effect on the side of the tooth groove.

[0046] Also need to explain, the left part of the sliding piece 522 is blocky, the right part is rod-shaped, the rod-shaped structure of the sliding piece 522 is provided with a groove for inserting the scraping piece 53, when the scraping piece 53 is inserted into the rod-shaped structure of the sliding piece 522, the scraping piece 53 and the sliding piece 522 are fixedly connected together through the pin, so as to facilitate the replacement of the scraping piece 53, the pin is not shown in the figure.

[0047] In order to abut the blocking strip 512 on the side of the tooth groove, the present application designs the following structure: refer to Figure 3 , Figure 5 and Figure 6 , the sharp head plate 511 is slidably arranged on the lower side of the bearing plate 51, the blocking strip 512 in the corresponding position in front and back is slidably connected with the corresponding inclined surface of the sharp head plate 511, and the gas cylinder 513 with the telescopic section fixedly connected with the sharp head plate 511 is fixedly installed on the support plate 3.

[0048] When it is needed to move the blocking strip 512 to the direction close to the side of the tooth groove, the telescopic sections of the two gas cylinders 513 are extended at the same time, so that the gas cylinder 513 pushes the sharp head plate 511 in the corresponding position to the right, the sharp head plate 511 pushes the blocking strip 512 in the corresponding position to the front and back sides, so that the upper blocking strip 512 abuts on the side of the tooth groove first.

[0049] In order to ensure the fine adjustment accuracy of the two induction blocks 42, so that the distance between the working surface of the induction block 42 and the side of the tooth groove is constant, the present application designs the following structure: refer to Figure 3 and Figure 4 , the moving plate 41 is fixedly connected with the support plate 3 through the fastening screw, the helical spring is arranged between the two receiving plates 43, and the receiving plate 43 is made of insulating and heat insulating material.

[0050] Refer to Figure 3 and Figure 7 , the limit plate 524 is connected together through the left and right sliding dismounting mode between the two corresponding positions of the linkage plates 523, and the ceramic pad is fixedly installed on the side close to the bearing plate 51 of the limit plate 524.

[0051] When the two induction blocks 42 are connected to the corresponding position of the receiving plate 43, the operator manually extrudes the two induction blocks 42, so that the two induction blocks 42 are located between the front and rear two linkage plates 523, and then the operator holds the limiting plate 524 and moves it horizontally and simultaneously slides and inserts it between the upper and lower two corresponding positions of the linkage plate 523, so that the upper and lower two linkage plates 523 can move forward and backward synchronously through the limiting plate 524, and at the same time, the two induction blocks 42 are located between the two limiting plates 524.

[0052] Then remove the external force on the two induction blocks 42, so that the spiral spring pushes the two receiving plates 43 away from each other through its own elastic force, and the receiving plate 43 drives the induction block 42 to move to abut against the ceramic pad of the limiting plate 524, so that the induction block 42 moves forward and backward synchronously with the linkage plate 523 and the blocking bar 512, and then when the blocking bar 512 abuts against the side of the gear slot, the induction block 42 moves to a position where the working surface thereof has a certain gap with the side of the gear slot, and through the pushing of the elastic force of the spiral spring, the gap between the working surface of the induction block 42 and the side of the gear slot is kept constant.

[0053] It should be noted that when the induction block 42 moves to the middle part of the gear slot, the upper two blocking bars 512 and the lower two blocking bars 512 can simultaneously contact the side of the gear slot, so that when the upper two blocking bars 512 move to the upper part of the gear, the lower two blocking bars 512 can continue to limit the induction block 42, thereby ensuring that the gap between the working surface of the induction block 42 and the side of the gear slot is constant.

[0054] In order to ensure the stable connection of the limiting plate 524 and the linkage plate 523, while maintaining the quick disassembly of the limiting plate 524 and the linkage plate 523, the present application designs the following structure: refer to Figure 7 , two dome columns 525 arranged in the upper and lower positions are arranged in the limiting plate 524 to slide up and down, a return spring is arranged between the dome column 525 and the limiting plate 524, and a hemispherical groove for inserting the dome column 525 is formed in the linkage plate 523 corresponding to the position of the dome column 525.

[0055] When the limiting plate 524 is slidably inserted into the linkage plate 523, the dome structure of the dome column 525 on the limiting plate 524 contacts the edge position of the linkage plate 523, so that the edge position of the linkage plate 523 pushes the dome column 525 to the inside of the limiting plate 524 and compresses the return spring at the corresponding position. When the limiting plate 524 is completely connected to the linkage plate 523, the dome column 525 moves and is inserted into the corresponding hemispherical groove under the pushing of the return spring, thereby locking the limiting plate 524 and the linkage plate 523 to a certain extent.

[0056] In order to improve the cleaning effect of the scraping sheet 53 on the side of the gear slot, the present application designs the following structure: refer to Figure 3 and Figure 5The outer edge positions of the scraping elastic pieces 53 on the same group of sliding pieces 522 gradually expand outward from top to bottom, the middle part of the scraping elastic piece 53 is in a hollow structure, and the outer edge positions of the scraping elastic piece 53 are provided with carbon guide grooves at equal intervals along the edge track.

[0057] When the scraping elastic piece 53 moves upward, the scraping elastic piece 53 at the same guide plate 521 sequentially contacts the tooth groove side from top to bottom, and due to the fact that the outer edge positions of the scraping elastic piece 53 on the same group of sliding pieces 522 gradually expand outward from top to bottom, the tooth groove side pushes the scraping elastic piece 53 at the same guide plate 521 from top to bottom by a reaction force, so that the deformation amount of the scraping elastic piece 53 gradually increases from top to bottom, and therefore the scraping elastic piece 53 on the same group of sliding pieces 522 can gradually increase the scraping force for cleaning the tooth groove side, and in combination with the vertically arranged multi-layer scraping elastic piece 53, the carbon deposition on the tooth groove is scraped in layers, so that the carbon cleaning effect is significantly improved, and due to the elastic force of the scraping elastic piece 53 itself, the adaptability to different tooth profiles is improved, and the cost is reduced.

[0058] When the scraping elastic piece 53 scrapes the tooth side, the left and right staggered carbon guide grooves can make the scraping elastic piece 53 completely cover the tooth side, promote the rapid falling of the carbon deposition, avoid the influence of the carbon deposition on the scraping efficiency of the scraping elastic piece 53, and maintain the continuous and stable carbon cleaning ability.

[0059] In order to remove the carbon deposition on the working surface of the induction block 42 and ensure that the heat conduction effect of the induction block 42 on each tooth groove is uniform, the present application designs the following structure: Figure 1 、 Figure 2 and Figure 8 The scraping assembly 54 comprises a U-shaped frame 541 fixedly installed on the upper side of the clamp tool 1, two front and rear arranged swing plates 542 are hinged to the left side of the longitudinal section of the U-shaped frame 541, and a plurality of scraping plates 543 sliding in the thickness direction are arranged at equal intervals along the length direction of the swing plate 542.

[0060] Referring to Figure 2 and Figure 8 A torsion spring is arranged between the swing plate 542 and the U-shaped frame 541, a tension spring is arranged between the scraping plate 543 and the swing plate 542, and the length of the scraping 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 are in a V-shaped structure with the opening facing left, when the induction block 42 moves up to the position corresponding to the swing plate 542, the induction block 42 is moved to the right, so that the induction block 42 is inserted between the swing plates 542, so that the working surface of the induction block 42 is in contact with and moves relative to the scraping plate 543, and then the scraping plate 543 scrapes the carbon deposition on the working surface of the induction block 42.

[0062] Need to explain, through the change of the angle of swing plate 542, and the induction block 42 push scraping plate 543 along the thickness of swing plate 542 moves, can make scraping plate 543 adapt to different shape induction block 42, in the guarantee cleaning effect at the same time, replace induction block 42 without replacing swing plate 542 and scraping plate 543, reduce the cost, ensure the convenience of operation.

[0063] Need to be particularly emphasized, the increased scraping elastic sheet 53 of the present application can be formed by a punch once, the material is elastic sheet material, low price, and the difficulty of production is low, the efficiency is fast, although compared with the existing quenching equipment slightly improves the cost, but the real-time cleaning of scraping elastic sheet 53 to the gear groove can make the quenching and tempering process seamless, greatly increase the efficiency of heat treatment, the obtained benefit is much greater than the cost of scraping elastic sheet 53, and the elastic property of scraping elastic sheet 53 itself can also adapt to the gear groove specification within a certain range and its own wear, so that the adaptability of scraping elastic sheet 53 is strong, and the service life is long, which further improves the amount of benefits it brings.
