Abstract
Description
Technical Field
[0001] This invention relates to the field of grinding wheels, and more specifically to an alloy tooth grinding wheel and its manufacturing process. Background Technology
[0002] As an abrasive tool, grinding wheels are only suitable for removing edges, welds, burrs, and rough edges from metal surfaces and for repairing uneven surfaces. This limitation makes it difficult to ensure the utilization rate of grinding wheels.
[0003] Grinding wheels are typically manufactured using a one-piece machining process. If manufacturing defects exist in the finished product, it must be scrapped to ensure the quality of the grinding wheel, resulting in significant manufacturing losses. Because grinding wheels require machining operations (such as turning, milling, and grinding) to obtain the desired shape and size, and the abrasive material needs to be welded and installed in an inlay manner, the continuity and interoperability of the machining operations greatly affect the manufacturing time, thus limiting manufacturing efficiency and hindering mass production. Summary of the Invention
[0004] The purpose of this invention is to provide an alloy gear grinding wheel and its manufacturing process, which can reduce manufacturing losses and shorten the total manufacturing time, thereby ensuring manufacturing efficiency.
[0005] The technical solution adopted by the present invention to solve the above problems is:
[0006] An alloy gear grinding wheel, comprising:
[0007] The first wheel is circular in shape. Several toothed grooves are formed on the top surface of the first wheel. The toothed grooves are arranged in a staggered circular pattern around the central axis of the first wheel, and alloy teeth are fixed inside the toothed grooves.
[0008] The second disc is circular in shape. A groove is provided on the top surface of the second disc to accommodate and fix the first disc. The edge of the second disc is provided with serrations. The serrations are arranged in a circular pattern around the central axis of the second disc, with each serration adjacent to the other in the same direction.
[0009] The present invention also provides a manufacturing process for the alloy gear grinding wheel based on the above technical solution, comprising the following steps:
[0010] Step S1: The first and second discs are respectively transported to the drilling station and the cutting station. The drilling mechanism drills several grooves on the top surface of the first disc, and the cutting mechanism cuts several serrations on the edge of the second disc.
[0011] Step S2: The first and second discs processed in step S1 are arranged vertically and simultaneously transported to the transfer tray located at the loading station.
[0012] Step S3: The first and second wheel disks located at the loading station are sequentially transferred to the first feeding station, the second feeding station, and the unloading station by rotating the transfer disk. The brazing powder is dropped from top to bottom into the tooth groove of the first wheel disk and the groove of the second wheel disk by the powder dropping mechanism at the first feeding station. The alloy teeth are dropped from top to bottom into the tooth groove of the first wheel disk by the unloading mechanism at the second feeding station.
[0013] Step S4: The first and second discs located at the unloading station in step S3 are arranged vertically on the transfer plate and synchronously transported to the assembly station. Then, the first disc is transported into the groove of the second disc by the moving mechanism, and the assembled first and second discs are transported from the assembly station to the brazing station.
[0014] Step S5: The first and second grinding wheels located at the brazing station are heated and brazed by the heating mechanism. After the first and second grinding wheels cool down, they are transported from the brazing station to the recycling station to collect the manufactured grinding wheels.
[0015] As a further improvement to the above technical solution, in step S1, the first wheel and the second wheel are conveyed by two plate conveyor belts arranged in parallel, and the conveying directions of the two are the same. The first wheel and the second wheel are placed on the two plate conveyor belts respectively by means of positioning posts sleeved on the chain plates of the plate conveyor belts.
[0016] As a further improvement to the above technical solution, in step S1, when the drilling mechanism processes the first wheel and the cutting mechanism processes the second wheel, both the first wheel and the second wheel are in a limited position and can rotate intermittently.
[0017] As a further improvement to the above technical solution, in step S1, the grooving mechanism moves along the direction perpendicular to the first wheel to groove, and after the first wheel rotates intermittently, it first moves horizontally a certain distance along the radial direction of the first wheel to adjust the grooving position, and then grooves.
[0018] The cutting mechanism moves along the direction perpendicular to the second disc to perform cutting. After the first disc rotates intermittently, it first rotates horizontally at a certain angle along the direction parallel to the first disc to adjust the cutting angle before cutting.
[0019] As a further improvement to the above technical solution, step S2 further includes blowing and removing chips from the first and second discs by a blowing mechanism at the cleaning station, and then transferring the first and second discs from the cleaning station to the transfer plate by a transfer unit located on the transfer plate at the loading station.
[0020] As a further improvement to the above technical solution, in step S3, the powder feeding mechanism intermittently outputs brazing powder in a circular shape to the top surface of the first disc, and then pushes the brazing powder on the top surface of the first disc away. The pushed-away brazing powder falls from top to bottom into the groove of the second disc located directly below the first disc, and then pushes the brazing powder on the top surface of the second disc away.
[0021] As a further improvement to the above technical solution, in step S3, the material feeding mechanism transports the alloy teeth to the top of the first wheel, so that the alloy teeth can fall into the tooth groove when they are directly above the tooth groove. During this process, the alloy teeth are moved so that they can fall into the tooth groove after their position changes.
[0022] As a further improvement to the above technical solution, in step S4, after the transfer unit transfers the first and second discs on the transfer tray at the unloading station to the assembly station, the moving mechanism clamps the first disc and supports the second disc at the assembly station, so that the transfer unit can be reset onto the transfer tray. Then, the first disc is placed from top to bottom into the groove of the second disc and then transported together from top to bottom to the brazing station.
[0023] As a further improvement to the above technical solution, in step S5, the heating mechanism performs heating and brazing on the assembled first and second discs by means of high-frequency electromagnetic induction heating.
[0024] Compared with the prior art, the present invention has the following advantages and effects:
[0025] (1) In this invention, the grinding wheel can be used for grinding and cutting through the alloy teeth on the first wheel disc and the saw teeth on the second wheel disc, which improves the usage of the grinding wheel and ensures the utilization rate of the last wheel. At the same time, since the grinding wheel has a modular structure, the various components of the grinding wheel can be made of different materials and manufactured separately, reducing manufacturing losses and thus reducing production costs.
[0026] (2) The present invention simultaneously drills and cuts the first and second discs, and then combines the sequential application of brazing powder on the first and second discs and the addition of alloy teeth on the first disc, thereby enabling the alloy teeth, the first disc and the second disc to be brazed and fixed in sequence, thus realizing the manufacturing of the grinding wheel. While ensuring the manufacturing quality of the grinding wheel, the processing operations of the first and second discs can be overlapped, ensuring the manufacturing efficiency of the grinding wheel.
[0027] (3) The present invention achieves two feeding operations (i.e., the addition of brazing powder and the addition of alloy teeth) in pairs of first and second discs by rotating them, thereby enabling multiple pairs of first and second discs to overlap during the two feeding operations, shortening the total time for manufacturing multiple grinding wheels and improving production efficiency.

Detailed Implementation
[0058] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.
[0059] Example 1.
[0060] See Figure 1 , Figure 2 This embodiment discloses an alloy tooth grinding wheel, including a first wheel 100 and a second wheel 101. Both the first wheel 100 and the second wheel 101 are annular. The top surface of the first wheel 100 is provided with a plurality of tooth grooves 102. Each tooth groove 102 is arranged in a staggered annular shape around the central axis of the first wheel 100. Alloy teeth 103 are fixed in the tooth grooves 102. The top surface of the second wheel 101 is provided with a groove 104 for accommodating and fixing the first wheel 100. Sawtooth teeth 105 are provided on the edge of the second wheel 101. Each sawtooth tooth 105 is arranged in annular shape around the central axis of the second wheel 101, with the ends of the teeth adjacent to each other.
[0061] In this embodiment, the alloy teeth 103, the first wheel 100, and the second wheel 101 are all fixed together by welding.
[0062] Example 2.
[0063] See Figures 3-29 This embodiment describes a manufacturing process for the alloy gear grinding wheel described in Embodiment 1, which includes the following steps:
[0064] Step S1: The first wheel 100 and the second wheel 101 are respectively transported to the drilling station 2 and the cutting station 3. The drilling mechanism 21 drills a number of grooves 102 on the top surface of the first wheel 100, and the cutting mechanism 31 cuts a number of serrations 105 on the edge of the second wheel 101.
[0065] Step S2: The first wheel 100 and the second wheel 101, which were processed in step S1, are arranged vertically and simultaneously transported to the transfer plate 41 located at the loading station 4.
[0066] In step S3, the first wheel 100 and the second wheel 101 located on the loading station 4 are sequentially transferred to the first feeding station 5, the second feeding station 6 and the unloading station 7 by rotating the transfer plate 41. The brazing powder is dropped from top to bottom into the tooth groove 102 of the first wheel 100 and the groove 104 of the second wheel 101 by the powder dropping mechanism 51 on the first feeding station 5. The alloy tooth 103 is dropped from top to bottom into the tooth groove 102 of the first wheel 100 by the unloading mechanism 61 on the second feeding station 6.
[0067] In step S4, the first wheel 100 and the second wheel 101 located at the unloading station 7 in step S3 are arranged vertically on the transfer plate 41 and synchronously transported to the assembly station 8. Then, the first wheel 100 is transported into the groove 104 of the second wheel 101 by the moving mechanism 81, and the assembled first wheel 100 and second wheel 101 are transported from the assembly station 8 to the brazing station 9.
[0068] In step S5, the first wheel 100 and the second wheel 101 located on the brazing station 9 are heated and brazed by the heating mechanism 91. After the first wheel 100 and the second wheel 101 are cooled, they are transported from the brazing station 9 to the recycling station 11 to collect the manufactured grinding wheel.
[0069] See Figures 4-6 In step S1, the first disc 100 and the second disc 101 are conveyed by two plate conveyor belts 12 arranged vertically and horizontally, respectively, and the conveying directions of the two are the same. The first disc 100 and the second disc 101 are placed on the two plate conveyor belts 12 respectively by means of positioning posts 122 sleeved on the chain plate 121 of the plate conveyor belt 12. This ensures the stability of the conveying of the first disc 100 and the second disc 101 by the two plate conveyor belts 12, thereby ensuring that the first disc 100 and the second disc 101 are processed in pairs in the subsequent process, and ensuring the smoothness of grinding wheel manufacturing.
[0070] See Figure 6 , Figure 7 In step S1, when the drilling mechanism 21 processes the first wheel 100 and the cutting mechanism 31 processes the second wheel 101, both the first wheel 100 and the second wheel 101 are in a limited position and can rotate intermittently.
[0071] In this embodiment, both the drilling station 2 and the cutting station 3 are limited by the clamping unit 13 to limit the first wheel 100 and the second wheel 101 respectively. The clamping unit 13 includes two first clamping seats 131. The two first clamping seats 131 in the two clamping units 13 are symmetrically arranged to the left and right with respect to the conveying direction of the first wheel 100 and the second wheel 101 respectively. The first clamping seats 131 are horizontally slidably arranged on the machine body 1. The two first clamping seats 131 are synchronously slid in opposite directions by the first driving device. Two driving wheels 132 are rotatably arranged on the opposite sides of the two first clamping seats 131 and the driving wheels 132 are exposed between the two first clamping seats 131. The two driving wheels 132 are symmetrically arranged to the left and right with respect to the first clamping seats 131. A first driving motor 133 for driving any one of the two driving wheels 132 to rotate is installed on the first clamping seat 131.
[0072] In this embodiment, the first driving device is a dual-output shaft motor, and the two first clamping seats 131 are respectively sleeved on the output shafts at both ends of the dual-output shaft motor in a threaded manner.
[0073] In use, the first driving device drives the two first clamping seats 131, causing the two first clamping seats 131 in the two clamping units 13 to clamp the first wheel 100 and the second wheel 101 respectively, thus limiting the position of the first wheel 100 and the second wheel 101. At the same time, the first driving motor 133 drives the driving wheel 132, causing the first wheel 100 and the second wheel 101 to rotate, thereby adjusting the processing position on the first wheel 100 and the second wheel 101. In order to ensure the stability of the rotation of the first wheel 100 and the second wheel 101, the two driving wheels 132 that rotate between the two first clamping seats 131 via the first driving motor 133 are arranged diagonally.
[0074] To ensure the accuracy of the two plate conveyor belts 12 in conveying the first wheel 100 and the second wheel 101 to the drilling station 2 and the cutting station 3 respectively, both the drilling station 2 and the cutting station 3 are equipped with a toggle mechanism 14. The toggle mechanism 14 includes two toggle units 141 arranged symmetrically to the left and right of the conveying direction of the plate conveyor belts 12. The toggle unit 141 includes a toggle rod 142, which is rotatably mounted on the machine body 1. A first motor is installed on the machine body 1 to drive the toggle rod 142 to rotate relative to the machine body 1. The two toggle rods 142 in the same toggle mechanism 14 rotate in opposite directions.
[0075] See Figure 8 , Figure 9 In step S1, the grooving mechanism 21 moves along the direction perpendicular to the first wheel 100 to groove, and after the first wheel 100 rotates intermittently, it first moves horizontally a certain distance along the radial direction of the first wheel 100 to adjust the grooving position, and then grooves.
[0076] The cutting mechanism 31 moves along the direction perpendicular to the second wheel 101 to perform cutting. After the first wheel 100 rotates intermittently, it first rotates horizontally at a certain angle along the direction parallel to the first wheel 100 to adjust the cutting angle before cutting.
[0077] In this embodiment, the grooving mechanism 21 is located between two first clamping seats 131. The grooving mechanism 21 includes a first lifting seat 22 and a first sliding seat 23. The first lifting seat 22 is vertically slidably disposed on the machine body 1. A first linear drive device 24 for driving the first lifting seat 22 to slide relative to the machine body 1 is installed on the machine body 1. The first sliding seat 23 is horizontally slidably disposed on the first lifting seat 22. A second linear drive device 25 for driving the first sliding seat 23 to slide relative to the first lifting seat 22 is installed on the first lifting seat 22. A drill bit 26 is rotatably disposed on the first sliding seat 23 and a second drive motor 27 for driving the drill bit 26 to rotate relative to the first sliding seat 23 is installed on it.
[0078] In use, the first linear drive device 24 drives the first lifting seat 22, controlling the contact and separation between the drill bit 26 and the first wheel 100. Combined with the drive effect of the second drive motor 27 on the drill bit 26, the drill bit 26 performs grooving operations on the top surface of the first wheel 100. Simultaneously, the second linear drive device 25 drives the first sliding seat 23, allowing adjustment of the drill bit 26 at different contact positions along the same radial direction of the first wheel 100. Combined with the rotation of the first wheel 100, this enables the drill bit 26 to form staggered grooves 102 on the top surface of the first wheel 100.
[0079] In this embodiment, the cutting mechanism 31 is located between two first clamping seats 131. The cutting mechanism 31 includes a second lifting seat 32 and a rotating seat 33. The second lifting seat 32 is vertically slidably disposed on the machine body 1. A third linear drive device 34 for driving the second lifting seat 32 to slide relative to the machine body 1 is installed on the machine body 1. The rotating seat 33 is horizontally rotatably disposed on the second lifting seat 32. A third drive motor 35 for driving the rotating seat 33 to rotate relative to the second lifting seat 32 is installed on the second lifting seat 32. A cutting blade 36 is vertically rotatably disposed on the rotating seat 33 and a fourth drive motor 37 for driving the cutting blade 36 to rotate relative to the rotating seat 33 is installed on the rotating seat 33.
[0080] In use, the third linear drive device 34 drives the second lifting seat 32, controlling the contact and separation between the cutting blade 36 and the second disc 101. Combined with the driving effect of the fourth drive motor 37 on the cutting blade 36, the cutting blade 36 performs cutting operations on the edge of the second disc 101. Simultaneously, the third drive motor 35 drives the rotating seat 33, adjusting the cutting angle of the cutting blade 36 so that it can cut serrations 105 on the edge of the second disc 101. Combined with the rotation of the second disc 101, this results in the cutting blade 36 forming a circular array of serrations 105 arranged end-to-end on the edge of the second disc 101.
[0081] See Figures 10-15 In step S2, the first and second discs 100 are blown and shavings are removed by the blowing mechanism 151 on the cleaning station 15, and then the first and second discs 100 are transferred from the cleaning station 15 to the transfer plate 41 by the transfer unit 42 on the transfer plate 41 located at the loading station 4.
[0082] In this embodiment, the blowing mechanism 151 includes two fans 152. The fans 152 blow air in a horizontal direction. The first wheel 100 and the second wheel 101 located at the cleaning station 15 are respectively located on the air blowing trajectory of the two fans 152, so that the metal chips remaining from drilling on the first wheel 100 and cutting on the second wheel 101 can be blown away by the wind, reducing the impact of metal chip residue on the manufacturing quality of the grinding wheel.
[0083] In this embodiment, the transfer disk 41 is rotatably mounted on the machine body 1. A second motor for driving the transfer disk 41 to rotate is installed on the machine body 1. A transfer cavity 43 is opened on the transfer disk 41 along its radial direction. The transfer unit 42 is located in the transfer cavity 43. The transfer unit 42 includes a second sliding seat 44. The second sliding seat 44 is horizontally slidably mounted on the transfer disk 41 along its radial direction. A fourth linear drive device 45 for driving the second sliding seat 44 to slide relative to the transfer disk 41 is installed on the transfer disk 41. A third lifting seat 46 is vertically slidably mounted on the second sliding seat 44 and a fifth linear drive device 47 for driving the third lifting seat 46 to slide relative to the second sliding seat 44 is installed on it. The third lifting seat 46 is provided with two extension arms 48 arranged vertically and parallel to each other. The extension arms 48 are provided with protrusions 49 for inserting into the first wheel 100 or the second wheel 101.
[0084] In use, the second sliding seat 44 is driven by the fourth linear drive device 45, causing the second sliding seat 44 to move horizontally together with the third lifting seat 46, so that the protrusions 49 on the two extension arms 48 are respectively located directly below the first wheel 100 and the second wheel 101 that need to be transported to the transfer tray 41. Then, the third lifting seat 46 is driven by the fifth linear drive device 47, so that the protrusions 49 on the two extension arms 48 can be inserted into the first wheel 100 and the second wheel 101 respectively. Then, the second sliding seat 44 is driven to reset by the fourth linear drive device 45, so that the first wheel 100 and the second wheel 101 slide under the pull of the extension arms 48 until they move onto the transfer tray 41.
[0085] To improve the continuity of the grinding wheel manufacturing process and enable overlapping of processing operations at each station, the transfer disk 41 is provided with four transfer chambers 43 corresponding to the loading station 4, the first feeding station 5, the second feeding station 6, and the unloading station 7. The four transfer chambers 43 are arranged in a circular shape at equal angles around the central axis of the transfer disk 41.
[0086] See Figures 16-20In step S3, the powder feeding mechanism 51 intermittently outputs brazing powder in a circular shape to the top surface of the first wheel 100, and then pushes the brazing powder on the top surface of the first wheel 100 away. The pushed brazing powder falls from top to bottom into the groove 104 of the second wheel 101 located directly below the first wheel 100, and then pushes the brazing powder on the top surface of the second wheel 101 away.
[0087] In this embodiment, the powder dispensing mechanism 51 includes a powder cylinder 52 for storing brazing powder. The powder cylinder 52 is vertically slidably mounted on the machine body 1. A sixth linear drive device 53 is installed on the machine body 1 to drive the powder cylinder 52 to slide relative to the machine body 1. The powder cylinder 52 is a cylindrical structure with a closed top and an open bottom. A rotating sleeve 54 is horizontally rotatably mounted on the bottom end of the powder cylinder 52, and a fifth drive motor 55 is installed to drive the rotating sleeve 54 to rotate relative to the powder cylinder 52. The fifth drive motor 55 and the rotating sleeve 54 are connected by a gear transmission mechanism 56. A powder outlet 541 is provided on the bottom surface of the rotating sleeve 54, and a sealing member 57 is provided on the powder outlet 541. The sealing member 57 is horizontally rotatably mounted on the rotating sleeve 54, and both are connected by a gear transmission mechanism 56. A torsion spring is provided between the powder cylinder 52 and a number of actuating blocks 58 are provided on the powder cylinder 52 for actuating the closing part 57 relative to the rotating sleeve 54. Each actuating block 58 is arranged at equal angles around the central axis of the powder cylinder 52. Two powder pushing units 59 are provided in the transfer cavity 43. The powder pushing unit 59 includes a powder pushing seat 591. The powder pushing seat 591 is T-shaped to prevent the second sliding seat 44 from sliding relative to the machine body 1. The powder pushing seat 591 is horizontally slidably set on the transfer disk 41. A seventh linear drive device 592 is installed on the transfer disk 41 for driving the powder pushing seat 591 to slide relative to the transfer disk 41. The bottom surfaces of the two powder pushing seats 591 are on the same horizontal plane as the top surfaces of the first wheel 100 and the second wheel 101, respectively.
[0088] In use, the sixth linear drive device 53 drives the powder cylinder 52, causing the powder outlet 541 to approach the top surface of the first wheel 100. Then, the fifth drive motor 55 drives the rotating sleeve 54, causing the rotating sleeve 54 to rotate. During this rotation, the actuating block 58 actuates the sealing member 57, and the torsion spring resets the sealing member 57, causing the powder outlet 541 to open intermittently. This creates an intermittent powder falling effect in a circular trajectory on the top surface of the first wheel 100. Then, the seventh linear drive device 592 in the powder pushing unit 59 corresponding to the first wheel 100 drives the powder pushing seat 591. The driving effect causes the brazing powder on the top surface of the first disc 100 to fall into the tooth groove 102 under the push of the powder pusher 591 or fall into the groove 104 of the second disc 101 located directly below the first disc 100 through the transfer cavity 43. Then, through the driving effect of the seventh linear drive device 592 in the powder pusher unit 59 corresponding to the second disc 101, the brazing powder on the top surface of the second disc 101 falls into the groove 104 or the bottom of the transfer cavity 43 under the push of the powder pusher 591, thereby completing the addition operation of brazing powder in the tooth groove 102 of the first disc 100 and in the groove 104 of the second disc 101.
[0089] To reduce the waste of brazing powder during the powder dropping process, a powder dropping port 431 is provided on the bottom surface of the transfer chamber 43, and a recycling cylinder 16 is provided on the machine body 1. The opening at the top of the recycling cylinder 16 is located directly below the powder dropping port 431, so that the brazing powder at the bottom of the transfer chamber 43 can enter the recycling cylinder 16 through the powder dropping port 431 and can be reused later.
[0090] See Figures 21-25 In step S3, the material feeding mechanism 61 conveys the alloy tooth 103 to the top of the first wheel 100, so that the alloy tooth 103 can fall into the tooth groove 102 when it is directly above the tooth groove 102. During this process, the alloy tooth 103 is moved so that it can fall into the tooth groove 102 after its position changes.
[0091] In this embodiment, the material feeding mechanism 61 includes a third sliding seat 62 and a material feeding box 63 for horizontally storing the alloy teeth 103. The third sliding seat 62 is horizontally slidably disposed on the machine body 1. An eighth linear drive device 64 for driving the third sliding seat 62 to slide relative to the machine body 1 is installed on the machine body 1. The top surface of the third sliding seat 62 and the top surface of the first wheel 100 are on the same horizontal plane and can be joined together. The material feeding box 63 is horizontally slidably disposed on the third sliding seat 62. A device for driving the material feeding box 63 to slide relative to the third sliding seat 62 is installed on the third sliding seat 62. The ninth linear drive device 65 has a bottom surface of a material box 63 that is on the same horizontal plane as the top surface of the first wheel 100. A discharge port 631 is provided on the bottom surface of the material box 63 along its axial direction. The first wheel 100 is located on the moving trajectory of the discharge port 631. A through hole 632 is provided on the side of the material box 63 located at its front end in the direction of movement towards the first wheel 100. The through hole 632 is connected to the discharge port 631. A horizontally rotatable actuating wheel 66 for actuating the alloy teeth 103 is provided inside the material box 63, and a sixth drive motor 67 for driving the actuating wheel 66 to rotate is installed.
[0092] In use, the third sliding seat 62 is moved into the transfer chamber 43 and engaged with the first wheel 100 by the driving effect of the eighth linear drive device 64. Then, the material box 63 is moved to the position directly above the first wheel 100 by the driving effect of the ninth linear drive device 65. During this process, when the alloy teeth 103 in the material box 63 move directly above the tooth groove 102, they fall into the tooth groove 102, realizing the alloy teeth 103 in the tooth groove 102. The installation of 3 is then carried out, and the sixth drive motor 67 drives the actuating wheel 66 to rotate and actuate the alloy teeth 103, causing the alloy teeth 103 to move and fall into the tooth groove 102. Subsequently, the ninth linear drive device 65 drives the material box 63 to reset. Since the alloy teeth 103 fall into the tooth groove 102, their length in the material box 63 is shortened, so that they can be moved out of the material box 63 through the through hole 632, thus completing the addition of the alloy teeth 103 in the tooth groove 102 of the first wheel 100.
[0093] In this embodiment, if the number of alloy teeth 103 in the discharge box 63 is too small, the space between the alloy teeth 103 will be too large, causing the alloy teeth 103 to tip over. To ensure the discharge effect of the discharge box 63, the discharge mechanism 61 can replenish the alloy teeth 103 that are reduced in the discharge box 63 after adding alloy teeth 103 on the first wheel 100. In this embodiment, the discharge mechanism 61 also includes a vibrating screen 68 for conveying alloy teeth 103. The discharge box 63 has a feed inlet 633, and a flap 69 is provided on the feed inlet 633. The flap 69 is rotatably mounted on the discharge box 63, and a torsion spring is provided between the flap 69 and the feed inlet 633 to drive the flap 69 to close the feed inlet 633. The feed port of the vibrating screen 68 is located on the moving trajectory of the feed inlet 633, so that the alloy teeth 103 in the discharge box 63 can be replenished by the vibrating screen 68 after they are reduced.
[0094] See Figures 26-29 In step S4, after the transfer unit 42 transfers the first disc 100 and the second disc 101 located on the transfer plate 41 at the unloading station 7 from the transfer plate 41 to the assembly station 8, the moving mechanism 81 clamps the first disc 100 and supports the second disc 101 located at the assembly station 8, so that the transfer unit 42 can be reset onto the transfer plate 41. Then, the first disc 100 is placed from top to bottom into the groove 104 of the second disc 101 and then transported together from top to bottom to the brazing station 9.
[0095] In this embodiment, the moving mechanism 81 includes a fourth lifting seat 82 and a fifth lifting seat 83. The fourth lifting seat 82 is vertically slidably disposed on the machine body 1. A tenth linear drive device 84 for driving the fourth lifting seat 82 to slide relative to the machine body 1 is installed on the machine body 1. Two second clamping seats 85 for clamping the first wheel 100 are horizontally slidably disposed on the fourth lifting seat 82, and a second drive device 86 for driving the two second clamping seats 85 to move synchronously in opposite directions is installed on them. The two second clamping seats 85 are positioned left and right relative to the first wheel 100. The fifth lifting seat 83 is vertically slidably mounted on the body 1. The body 1 is equipped with an eleventh linear drive device 87 for driving the fifth lifting seat 83 to slide relative to the body 1. When the second wheel 101 is located on the assembly station 8, the fifth lifting seat 83 is located directly below the second wheel 101. The bottom surface of the fifth lifting seat 83 is provided with two support columns 88 for supporting the second wheel 101. The two support columns 88 are symmetrically arranged on the left and right sides relative to the fifth lifting seat 83, and there is a space 89 between them for accommodating the extension arm 48.
[0096] In use, the fourth linear drive device 45 drives the second sliding seat 44, transporting the first wheel 100 and the second wheel 101 on the transfer tray 41 at the unloading station 7 to the assembly station 8. Then, the second drive device 86 drives the two second clamping seats 85, causing them to clamp the first wheel 100 on the assembly station 8. The eleventh linear drive device 87 drives the fifth lifting seat 83, causing it to support the second wheel 101 on the assembly station 8. Finally, the fifth linear drive device 47 drives the third lifting seat 46 to reset and... The second sliding seat 44 is reset by the fourth linear drive device 45, and the third lifting seat 46 and the second sliding seat 44 move back into the transfer cavity 43. Then, the first wheel 100 moves into the groove 104 of the second wheel 101 by the driving effect of the tenth linear drive device 84 on the fourth lifting seat 82. After the second clamping seat 85 releases the clamp on the first wheel 100, the assembly of the first wheel 100 and the second wheel 101 is completed. Finally, the first wheel 100 and the second wheel 101 are transported to the brazing station 9 located directly below the assembly station 8 by the driving effect of the eleventh linear drive device 87 on the fifth lifting seat 83.
[0097] In this embodiment, the second drive device 86 is a dual-output shaft motor, and the two second clamping seats 85 are respectively sleeved on the output shafts at both ends of the dual-output shaft motor in a threaded manner.
[0098] See Figure 29 In step S5, the heating mechanism 91 performs heating and brazing on the assembled first wheel 100 and second wheel 101 by means of high-frequency electromagnetic induction heating.
[0099] In this embodiment, the heating mechanism 91 includes a heating coil 92, and a fifth lifting seat 83 can be inserted through the heating coil 92. The diameter of the heating coil 92 is larger than the diameter of the second wheel 101. Two push-out seats 93 are horizontally slidably arranged on the machine body 1 to push the brazed grinding wheel from the brazing station 9 to the recycling station 11. A twelfth linear drive device 94 is installed to drive the push-out seats 93 to slide relative to the machine body 1. The push-out seats 93 are located below the heating coil 92 and the two push-out seats 93 are arranged symmetrically on the left and right sides relative to the fifth lifting seat 83.
[0100] In use, the eleventh linear drive device 87 drives the fifth lifting seat 83, causing the first wheel 100 and the second wheel 101 assembled on the fifth lifting seat 83 to be transported to the heating space of the heating coil 92. Under the heating effect of the heating coil 92, the brazing powder located in the tooth groove 102 and the groove 104 melts and fills the gap between the alloy tooth 103 and the first wheel 100, as well as between the first wheel 100 and the second wheel 101. After heating stops and cooling, the alloy tooth 103, the first wheel 100 and the second wheel 101 are welded together in sequence. Then, the eleventh linear drive device 87 drives the fifth lifting seat 83 to move, transporting the welded grinding wheel to the moving trajectory of the ejector seat 93. The twelfth linear drive device 94 drives the ejector seat 93 to push the grinding wheel from the brazing station 9 to the recycling station 11.
