Description

Technical Field

[0001] This invention relates to the field of grinding wheel manufacturing, and more specifically to an alloy tooth grinding wheel manufacturing production line. Background Technology

[0002] Grinding wheels are usually manufactured using a one-piece machining process. If there are manufacturing defects in the finished product, it needs to be scrapped in order to ensure the quality of the grinding wheel, resulting in significant manufacturing losses.

[0003] Because grinding wheels require machining head operations (such as turning, milling, grinding, etc.) to obtain the required grinding wheel shape and size, and the abrasive on the grinding wheel also needs to be welded and installed in an inlay manner, the connection and continuity of the processing and manufacturing operations greatly affect the manufacturing time of the grinding wheel, which limits the manufacturing efficiency of the grinding wheel and is not conducive to the mass production of grinding wheels. Summary of the Invention

[0004] The purpose of this invention is to provide an alloy tooth grinding wheel manufacturing production line that improves the convenience of grinding wheel manufacturing, ensures the manufacturing efficiency of grinding wheels, and shortens the manufacturing time of grinding wheels.

[0005] The technical solution adopted by the present invention to solve the above problems is:

[0006] An alloy gear grinding wheel manufacturing production line includes:

[0007] The grooving station drills several grooves on the top surface of the first disc using a grooving mechanism.

[0008] The cutting station uses a cutting mechanism to cut several serrations on the edge of the second disc;

[0009] At the loading station, the first wheel after drilling and the second wheel after cutting are arranged vertically and simultaneously transported to the transfer tray.

[0010] The first feeding station uses a powder feeding mechanism to drop brazing powder from top to bottom into the tooth groove of the first wheel and the groove on the second wheel used to accommodate and fix the first wheel.

[0011] The second feeding station uses a feeding mechanism to drop alloy teeth from top to bottom into the tooth groove of the first wheel;

[0012] At the unloading station, the first and second discs on the transfer tray are arranged vertically and simultaneously transported to the assembly station.

[0013] The assembly station uses a moving mechanism to transport the first wheel to the groove of the second wheel and then transports the assembled first and second wheels from the assembly station to the brazing station.

[0014] The brazing station uses a heating mechanism to heat and braze the first and second discs located at the brazing station.

[0015] Among them, the first and second discs, which are arranged vertically on the transfer plate, are transported sequentially from the loading station to the first feeding station, the second feeding station, and the unloading station by the rotation of the transfer plate.

[0016] As a further improvement to the above technical solution, both the drilling station and the cutting station are limited by clamping units to respectively limit the first and second discs. The clamping unit includes two first clamping seats. The two first clamping seats in the two clamping units are symmetrically arranged to the left and right with respect to the conveying direction of the first and second discs, respectively. The first clamping seats are horizontally slidably arranged on the machine body. The two first clamping seats are synchronously slid in opposite directions by a first driving device. Two driving wheels are rotatably arranged on the opposite sides of the two first clamping seats, and the driving wheels are exposed between the two first clamping seats. The two driving wheels are symmetrically arranged to the left and right with respect to the first clamping seats.

Detailed Implementation

[0053] 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.

[0054] See Figures 1-24This embodiment describes an alloy gear grinding wheel manufacturing production line, including a machine body 1. The machine body 1 is equipped with a drilling station 2, a cutting station 3, a loading station 4, a first feeding station 5, a second feeding station 6, a unloading station 7, an assembly station 8, and a brazing station 9. The drilling station 2 and the cutting station 3 are arranged vertically on the machine body 1. The drilling station 2 drills a plurality of grooves 101 on the top surface of the first grinding wheel 100 using a drilling mechanism 21. The cutting station 3 uses a cutting mechanism 31... Several serrations 103 are cut into the edge of the second disc 102. The loading station 4, the first feeding station 5, the second feeding station 6, and the unloading station 7 are arranged in a ring on the machine body 1. The first disc 100, which has completed the grooving, and the second disc 102, which has completed the cutting, are arranged vertically from the loading station 4 and simultaneously transported to the transfer plate 41. The first disc 100 and the second disc 102, which are arranged vertically on the transfer plate 41, are transported from the loading station 100 to the transfer plate 41 by the rotation of the transfer plate 41. Station 4 sequentially conveys materials to the first feeding station 5, the second feeding station 6, and the unloading station 7. The first feeding station 5 uses a powder-dropping mechanism 51 to drop brazing powder from top to bottom into the tooth groove 101 of the first wheel 100 and the groove 104 on the second wheel 102 used to accommodate and fix the first wheel 100. The second feeding station 6 uses a unloading mechanism 61 to drop alloy teeth 105 from top to bottom into the tooth groove 101 of the first wheel 100. The first wheel on the transfer tray 41... The first wheel 100 and the second wheel 102 are arranged vertically from the loading station 4 and synchronously transported to the assembly station 8. The assembly station 8 uses a moving mechanism 81 to transport the first wheel 100 into the groove 104 of the second wheel 102 and then transports the assembled first wheel 100 and the second wheel 102 from the assembly station 8 to the brazing station 9. The brazing station 9 uses a heating mechanism 91 to heat and braze the first wheel 100 and the second wheel 102 located on the brazing station 9.

[0055] In this embodiment, the structure of the alloy tooth 105 grinding wheel manufactured on the production line (such as...) Figure 23 , Figure 24 As shown, it includes a first wheel 100 and a second wheel 102. Both the first wheel 100 and the second wheel 102 are annular. The top surface of the first wheel 100 is provided with a plurality of toothed grooves 101. Each toothed groove 101 is arranged in a staggered annular shape around the central axis of the first wheel 100. Alloy teeth 105 are fixed in the toothed grooves 101. The top surface of the second wheel 102 is provided with a groove 104 for accommodating and fixing the first wheel 100. The edge of the second wheel 102 is provided with serrations 103. Each serration 103 is arranged in annular shape around the central axis of the second wheel 102, with the ends of the serrations adjacent to each other.

[0056] In this embodiment, the first wheel 100 and the second wheel 102 are respectively transported to the drilling station 2 and the cutting station 3 by two plate conveyor belts 11 arranged vertically and horizontally, and the two conveying directions are the same. The first wheel 100 and the second wheel 102 are respectively placed on the two plate conveyor belts 11 by means of positioning posts 13 sleeved on the chain plates 12 on the plate conveyor belts 11, which ensures the stability of the two plate conveyor belts 11 in transporting the first wheel 100 and the second wheel 102, thereby ensuring that the first wheel 100 and the second wheel 102 are processed in pairs in the subsequent process, and ensuring the smoothness of grinding wheel manufacturing.

[0057] See Figure 3 , Figure 4 The drilling station 2 and the cutting station 3 are both limited by the clamping unit 14 to limit the first wheel 100 and the second wheel 102 respectively. The clamping unit 14 includes two first clamping seats 141. The two first clamping seats 141 in the two clamping units 14 are symmetrically arranged to the left and right with respect to the conveying direction of the first wheel 100 and the second wheel 102 respectively. The first clamping seats 141 are horizontally slidably arranged on the machine body 1. The two first clamping seats 141 are synchronously slid in opposite directions by the first driving device 142. Two driving wheels 143 are rotatably arranged on the opposite sides of the two first clamping seats 141 and the driving wheels 143 are exposed between the two first clamping seats 141. The two driving wheels 143 are symmetrically arranged to the left and right with respect to the first clamping seats 141. A first driving motor 144 for driving any one of the two driving wheels 143 to rotate is installed on the first clamping seat 141.

[0058] In use, the first driving device 142 drives the two first clamping seats 141, causing the two first clamping seats 141 in the two clamping units 14 to clamp the first wheel 100 and the second wheel 102 respectively, thereby limiting the position of the first wheel 100 and the second wheel 102. At the same time, the first driving motor 144 drives the driving wheel 143, causing the first wheel 100 and the second wheel 102 to rotate, thereby adjusting the processing position on the first wheel 100 and the second wheel 102. In order to ensure the stability of the rotation of the first wheel 100 and the second wheel 102, the two driving wheels 143 that rotate between the two first clamping seats 141 via the first driving motor 144 are arranged diagonally.

[0059] In this embodiment, the first drive device 142 is a dual-output shaft motor, and the two first clamping seats 141 are respectively sleeved on the output shafts at both ends of the dual-output shaft motor in a threaded manner.

[0060] To ensure the accuracy of the two plate conveyor belts 11 in conveying the first wheel 100 and the second wheel 102 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 15. The toggle mechanism 15 includes two toggle units 151 arranged symmetrically to the left and right of the conveying direction of the plate conveyor belts 11. The toggle unit 151 includes a toggle rod 152, which is rotatably mounted on the machine body 1. A first motor is installed on the machine body 1 to drive the toggle rod 152 to rotate relative to the machine body 1. The two toggle rods 152 in the same toggle mechanism 15 rotate in opposite directions.

[0061] See Figure 5 The grooving mechanism 21 is located between two first clamping seats 141. 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.

[0062] 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 101 on the top surface of the first wheel 100.

[0063] See Figure 6 The cutting mechanism 31 is located between two first clamping seats 141. 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 it.

[0064] 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 102. Combined with the drive 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 102. 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 103 on the edge of the second disc 102. Combined with the rotation of the second disc 102, the cutting blade 36 forms a circular arrangement of serrations 103 on the edge of the second disc 102.

[0065] See Figure 7 Fans are provided between the grooving station 2 and the loading station 4, as well as between the cutting station 3 and the loading station 4. The fans blow air in a horizontal direction. The conveying trajectories of the first wheel 100 and the second wheel 102 intersect with the blowing trajectories of the two fans, so that the metal chips remaining from the grooving on the first wheel 100 and the cutting on the second wheel 102 can be blown away by the wind, reducing the impact of metal chip residue on the manufacturing quality of the grinding wheel.

[0066] See Figures 8-11 The transfer disk 41 is rotatably mounted on the machine body 1, and a second motor for driving the transfer disk 41 to rotate is installed on the machine body 1.

[0067] The transfer disk 41 has four transfer cavities 42 arranged at equal angles around its central axis along its radial direction. The four transfer cavities 42 correspond one-to-one with the loading station 4, the first feeding station 5, the second feeding station 6, and the unloading station 7, so that the processing operations of each station can overlap, thereby improving manufacturing efficiency while ensuring the continuity of the grinding wheel manufacturing process. The transfer cavity 42 is provided with a second sliding seat 43, which is horizontally slidably disposed on the transfer disk 41 along its radial direction. The transfer disk 41 is equipped with a fourth linear drive device 44 for driving the second sliding seat 43 to slide relative to the transfer disk 41. The second sliding seat 43 is vertically slidably disposed with a third lifting seat 45 and equipped with a fifth linear drive device 46 for driving the third lifting seat 45 to slide relative to the second sliding seat 43. The third lifting seat 45 is provided with two extension arms 47 arranged vertically and parallel to each other. The extension arms 47 are provided with protrusions 48 for being inserted into the first wheel disk 100 or the second wheel disk 102.

[0068] In use, the second sliding seat 43 is driven by the fourth linear drive device 44, causing the second sliding seat 43 to move horizontally together with the third lifting seat 45, so that the protrusions 48 on the two extension arms 47 are respectively located directly below the first wheel 100 and the second wheel 102 that need to be transported to the transfer tray 41. Then, the third lifting seat 45 is driven by the fifth linear drive device 46, so that the protrusions 48 on the two extension arms 47 can be inserted into the first wheel 100 and the second wheel 102 respectively. Then, the second sliding seat 43 is driven to reset by the fourth linear drive device 44, so that the first wheel 100 and the second wheel 102 slide under the pull of the extension arms 47 until they move onto the transfer tray 41.

[0069] See Figures 12-15 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 a gap is provided between the two. The powder cylinder 52 is equipped with a torsion spring and several actuating blocks 58 for actuating the closure 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. The transfer cavity 42 is equipped with two powder pushing units 59. Each powder pushing unit 59 includes a powder pushing seat 591. The powder pushing seat 591 is T-shaped to prevent the second sliding seat 43 from sliding relative to the machine body 1. The powder pushing seat 591 is horizontally slidably set on the transfer disk 41. The transfer disk 41 is equipped with a seventh linear drive device 592 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 102, respectively.

[0070] 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 101 under the push of the powder pusher 591 or fall into the groove 104 of the second disc 102 located directly below the first disc 100 through the transfer cavity 42. Then, through the driving effect of the seventh linear drive device 592 in the powder pusher unit 59 corresponding to the second disc 102, the brazing powder on the top surface of the second disc 102 falls into the groove 104 or the bottom of the transfer cavity 42 under the push of the powder pusher 591, thereby completing the addition operation of brazing powder in the tooth groove 101 of the first disc 100 and in the groove 104 of the second disc 102.

[0071] To reduce the waste of brazing powder during the powder dropping process, a powder dropping port 49 is provided on the bottom surface of the transfer chamber 42, and a recovery cylinder 16 is provided on the machine body 1. The opening at the top of the recovery cylinder 16 is located directly below the powder dropping port 49, so that the brazing powder at the bottom of the transfer chamber 42 can enter the recovery cylinder 16 through the powder dropping port 49 and can be reused later.

[0072] See Figures 16-18 The material feeding mechanism 61 includes a third sliding seat 62 and a feeding box 63 for horizontally storing the alloy teeth 105. 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 feeding box 63 is horizontally slidably disposed on the third sliding seat 62. A ninth linear drive device 64 for driving the feeding box 63 to slide relative to the third sliding seat 62 is installed on the third sliding seat 62. The linear drive device 65 has a bottom surface of the material box 63 that is on the same horizontal plane as the top surface of the first wheel 100. The bottom surface of the material box 63 has an outlet 631 along its axial direction. The first wheel 100 is located on the moving trajectory of the outlet 631. The side of the material box 63 located at its front end in the direction of movement towards the first wheel 100 has a through hole 632 that is connected to the outlet 631. The material box 63 has a horizontally rotatable actuating wheel 66 for actuating the alloy teeth 105 and a sixth drive motor 67 for driving the actuating wheel 66 to rotate.

[0073] In use, the third sliding seat 62 is moved into the transfer cavity 42 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 105 in the material box 63 move directly above the tooth groove 101, they fall into the tooth groove 101, realizing the alloy teeth 105 in the tooth groove 101. The installation of 5 is then carried out, and the sixth drive motor 67 drives the actuating wheel 66 to rotate and actuate the alloy tooth 105, causing the alloy tooth 105 to move and fall into the tooth groove 101. Subsequently, the ninth linear drive device 65 drives the material box 63 to reset. Since the alloy tooth 105 falls into the tooth groove 101, its length in the material box 63 is shortened, so that it can be moved out of the material box 63 through the through hole 632, thus completing the addition of the alloy tooth 105 in the tooth groove 101 of the first wheel 100.

[0074] See Figure 19 The material feeding mechanism 61 also includes a vibrating screen 68 for conveying alloy teeth 105. The material feeding box 63 is provided with a feed inlet 633 and a flap 69 is provided on the feed inlet 633. The flap 69 is rotatably mounted on the material feeding box 63 and a torsion spring is provided between the two for driving 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 after the alloy teeth 105 are added to the first wheel 100, the material feeding box 63 can be replenished with alloy teeth 105 through the vibrating screen 68. This reduces the situation where the alloy teeth 105 are overturned due to excessive space between them caused by insufficient number of alloy teeth 105 in the material feeding box 63, thereby ensuring the material feeding effect of the material feeding box 63.

[0075] See Figures 20-22The moving mechanism 81 includes a fourth lifting seat 82 and a fifth lifting seat 83. The fourth lifting seat 82 is vertically slidably mounted on the body 1. A tenth linear drive device 84 is installed on the body 1 to drive the fourth lifting seat 82 to slide relative to the body 1. Two second clamping seats 85 for clamping the first wheel 100 are horizontally slidably mounted on the fourth lifting seat 82, and a second drive device 86 is installed to drive the two second clamping seats 85 to move synchronously in opposite directions. The two second clamping seats 85 are symmetrically arranged relative to the first wheel 100. The fifth lifting seat 83 is vertically slidably mounted on the machine body 1. The machine body 1 is equipped with an eleventh linear drive device 87 for driving the fifth lifting seat 83 to slide relative to the machine body 1. When the second wheel 102 is located on the assembly station 8, the fifth lifting seat 83 is located directly below the second wheel 102. The bottom surface of the fifth lifting seat 83 is provided with two support columns 88 for supporting the second wheel 102. 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 47.

[0076] In use, the fourth linear drive device 44 drives the second sliding seat 43, transporting the first wheel 100 and the second wheel 102 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 102 on the assembly station 8. Finally, the fifth linear drive device 46 drives the third lifting seat 45 to reset and... The second sliding seat 43 is reset by the fourth linear drive device 44, and the third lifting seat 45 and the second sliding seat 43 are moved back into the transfer cavity 42. Then, the first wheel 100 is moved into the groove 104 of the second wheel 102 by the driving effect of the tenth linear drive device 84. 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 102 is completed. Finally, the first wheel 100 and the second wheel 102 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.

[0077] 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.

[0078] See Figure 22The 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 102. 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 17. 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.

[0079] In use, the eleventh linear drive device 87 drives the fifth lifting seat 83, causing the first wheel 100 and the second wheel 102 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 101 and the groove 104 melts and fills the gap between the alloy tooth 105 and the first wheel 100, as well as between the first wheel 100 and the second wheel 102. After heating stops and cooling, the alloy tooth 105, the first wheel 100 and the second wheel 102 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 17.
