[0002] The muffler tube is an important component of the muffler. It has a cylindrical structure with multiple holes on its outer wall to reduce noise. There are usually two ways to process the muffler tube: one is to first drill holes in a flat plate, then bend the plate into a roll and weld it. Although this method is convenient for drilling holes, it requires very high welding skills and it is difficult to produce a high-quality muffler tube. Therefore, the industry currently mostly uses the second processing method, which is to directly drill holes in the cylindrical tube.

[0003] In existing muffler pipe processing, the pipe is usually clamped manually before drilling, which is inefficient. Therefore, it is necessary to design a drilling device for muffler pipe processing to improve the processing efficiency. Utility Model Content

[0022] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-6 The present invention provides a technical solution: a drilling device for processing silencer pipes, including a workbench 1, wherein a feeding component 2, a fixing component 3 and a discharging component 4 are arranged sequentially along the length of the workbench 1.

[0024] like Figure 2 The feeding assembly 2 includes a horizontally arranged conveyor table 5, the length direction of which is consistent with the length direction of the worktable 1. Two hydraulic telescopic cylinders 6 are arranged on the side of the conveyor table 5 away from the fixing assembly 3. The two hydraulic telescopic cylinders 6 are respectively arranged at both ends of the conveyor table 5 along the width direction. The fixed ends of the two hydraulic telescopic cylinders 6 are fixedly connected to the fixing plates 7. The output ends of the two hydraulic telescopic cylinders 6 are fixedly connected to the conveyor table 5. The fixing plates 7 are fixedly connected to the worktable 1. The conveyor table 5 is slidably arranged along the length direction of the worktable 1. The output ends of the hydraulic telescopic cylinders 6 drive the conveyor table 5 to slide along the length direction of the worktable 1.

[0025] A slide groove 8 is provided on the upper side of the transmission platform 5 along the length direction. The cross-sectional shape of the slide groove 8 along the width direction of the transmission platform 5 is semi-circular. Several silencers are installed in the slide groove 8, and the silencers are concentrically arranged with the slide groove 8.

[0026] A linear motor 9 is provided on one side of the transmission platform 5 along the width direction. The linear motor 9 is fixedly connected to the transmission platform 5. A baffle 10 is fixedly connected to the output end of the linear motor 9. The baffle 10 is set vertically. The side of the baffle 10 near the transmission platform 5 is located above the slide 8. The lower side of the baffle 10 is in direct contact with the upper side of the transmission platform 5.

[0027] The output end of the linear motor 9 moves the control baffle 10, which pushes the muffler tube toward the fixed component 3, thereby realizing continuous transmission and drilling of the muffler tube and improving the drilling efficiency of the muffler tube.

[0028] like Figure 3 The fixed component 3 includes a frame 11, which is horizontally arranged along the width direction of the workbench 1. A cavity 12 is provided on the lower side of the frame 11, and a connecting block 13 is provided in the cavity 12.

[0029] like Figure 4 A cavity 14 is provided at the center of the connecting block 13 along the length of the workbench 1. A rotating shaft 15 is rotatably connected inside the cavity 14. The rotating shaft 15 and the cavity 14 are concentrically arranged.

[0030] like Figure 3 One end of the rotating shaft 15 along the axial direction is fixedly connected to a gear 16. The gear 16 is located outside the connecting block 13. The swing motor 17 is fixedly connected to the connecting block 13. The output end of the swing motor 17 is fixedly connected to a gear 2 18. The gear 2 18 meshes with the gear 16. The swing motor 17 can rotate at a fixed angle through the output shaft. Therefore, the rotating shaft 15 rotates at a fixed angle under the drive of the gear 2 18 and the gear 16.

[0031] like Figure 4 Both ends of the rotating shaft 15 along the axial direction are fixedly connected to round tubes 19. A muffler tube is sleeved on the round tube 19. The round tube 19 is concentric with the rotating shaft 15 and the slide groove 8. A baffle 49 is fixedly connected to the side of the round tube 19 near the rotating shaft 15. The baffle 49 is used to axially position the muffler tube sleeved on the round tube 19, thereby accurately drilling holes in the muffler tube.

[0032] The outer wall of the circular tube 19 has several sets of grooves 20 along the axial direction, and the several sets of grooves 20 are evenly distributed in a circle with the axis of the circular tube 19 as the center.

[0033] like Figure 5The groove 20 has circular holes 21 at both ends along its length. The tube 19 has a cavity 22. The circular holes 21 are connected to the cavity 22. A connecting post 23 is slidably connected inside the circular hole 21. The two connecting posts 23 are connected to a support rod 24 on the side away from the cavity 22. The length of the support rod 24 is consistent with the length of the groove 20. The radial section of the support rod 24 along the tube 19 is semi-circular.

[0034] A ball 25 is fixedly connected to one end of the connecting post 23 located in the cavity 22, and a spring 26 is sleeved on the part of the connecting post 23 located inside the cavity 22.

[0035] Two discs 27 are provided inside the cavity 3 22. The two discs 27 are located at both ends of the axis of the cavity 3 22. The discs 27 are concentric with the cavity 3 22. A groove 28 is provided on the circumference of the disc 27 corresponding to the ball 25. The ball 25 slides in the groove 28, thereby driving the connecting column 23 to slide in the circular hole 21, so that the support rod 24 can extend and retract radially along the cavity 3 22.

[0036] Two discs 27 are fixedly connected to opposite sides of a rotary motor 29, which is fixedly connected inside cavity 22. The rotary motor 29 drives the discs 27 to rotate, thereby causing the slide groove 28 to rotate. The side of the slide groove 28 away from the center of the disc 27 contacts the ball 25. Under the action of the slide groove 28, the ball 25 causes the support rod 24 to extend radially along cavity 22. The side of the support rod 24 away from cavity 22 supports and fixes the muffler tube sleeved on the round tube 19. The rotary motor 29 rotates in the opposite direction to make the side of the slide groove 28 closer to the center of the disc 27 contact the ball 25. Under the elastic action of the spring 26, the support rod 24 retracts into the groove 20 and no longer supports the muffler tube.

[0037] like Figure 3 Connecting block 13 is fixedly connected to rotating shaft 2 30 on both sides of the outer wall of workbench 1. The rotating shaft 2 30 is set vertically. One of the rotating shafts 2 30 near workbench 1 is rotatably connected to workbench 1. The rotating shaft 15 near frame 11 passes through frame 11 and is fixedly connected to swing motor 2 31. Swing motor 2 31 rotates connecting block 13 and the circular tube 19 connected to connecting block 13 at a fixed angle. Specifically, it rotates 180 degrees so that the circular tube 19 near the feeding component 2 is rotated to the discharge component 4 after drilling, and the drilled silencer tube is removed from the circular tube 19 by the discharge component 4.

[0038] like Figure 1 A drilling assembly 48 is provided on the side of cavity 12 near the feeding assembly 2.

[0039] like Figure 3The drilling assembly 48 includes two hydraulic telescopic cylinders 32, which are vertically arranged. The fixed ends of the hydraulic telescopic cylinders 32 are fixedly connected to the frame 11. The output ends of the two hydraulic telescopic cylinders 32 are fixedly connected to a connecting plate 33. The length direction of the connecting plate 33 is consistent with the length direction of the worktable 1. Several sets of rotary cylinders 34 are fixedly connected to the side of the connecting plate 33 away from the hydraulic telescopic cylinders 32. The rotary cylinders 34 are vertically arranged and arranged in a linear array along the length direction of the connecting plate 33. The fixed ends of the rotary cylinders 34 are fixedly connected to the connecting plate 33. The output ends of the rotary cylinders 34 are fixedly connected to a drill bit 35, which is used to drill holes in the silencer pipe.

[0040] Two hydraulic telescopic cylinders 36 are vertically arranged on the workbench 1, corresponding to the second hydraulic telescopic cylinder 32. The fixed ends of the third hydraulic telescopic cylinders 36 are fixedly connected to the workbench 1. The output ends of the two third hydraulic telescopic cylinders 36 are fixedly connected to the second connecting plate 37. The length direction of the second connecting plate 37 is consistent with the length direction of the workbench 1. Several sets of rotary cylinders 38 are fixedly connected to the side of the second connecting plate 37 away from the third hydraulic telescopic cylinders 36. The rotary cylinders 38 are vertically arranged, and the several sets of rotary cylinders 38 are arranged in a linear array along the length direction of the second connecting plate 37. The fixed ends of the rotary cylinders 38 are fixedly connected to the second connecting plate 37. The output ends of the rotary cylinders 38 are fixedly connected to the second drill bit 39, which is used to drill holes in the silencer pipe.

[0041] like Figure 6 The discharge assembly 4 includes a horizontally arranged conveyor platform 2 40. The length direction of the conveyor platform 2 40 is consistent with the length direction of the worktable 1. Two hydraulic telescopic cylinders 41 are arranged on the side of the conveyor platform 2 40 away from the fixed assembly 3. The two hydraulic telescopic cylinders 41 are respectively arranged at both ends of the conveyor platform 2 40 along the width direction. The fixed end of the hydraulic telescopic cylinder 41 is fixedly connected to the fixed plate 2 42. The fixed plate 2 42 is fixedly connected to the worktable 1. The conveyor platform 2 40 is slidably arranged along the length direction of the worktable 1. The output end of the hydraulic telescopic cylinder 41 pushes the conveyor platform 2 40 to slide along the length direction of the worktable 1.

[0042] A slide groove 43 is provided on the upper side of the transmission platform 2 40 along the length direction. The slide groove 43 is concentric with the circular tube 19. The cross section of the slide groove 43 along the width direction of the transmission platform 2 40 is semi-circular. Several sets of silencers are installed in the slide groove 43. The silencers are concentric with the slide groove 43, so that the silencers with holes can move along the slide groove 43 to the side away from the fixed component 3.

[0043] Two hydraulic telescopic cylinders 44 are installed on the side of the transmission platform 2 40 near the fixed component 3. The two hydraulic telescopic cylinders 44 are vertically arranged, and their fixed ends are fixedly connected to the upper side of the transmission platform 2 40. The two hydraulic telescopic cylinders 44 are symmetrically arranged with the axis of the slide groove 3 43 as the center. The output ends of the two hydraulic telescopic cylinders 44 are fixedly connected to the connecting block 2 45, which is "L" shaped. The end of the connecting block 2 45 away from the hydraulic telescopic cylinders 44 is fixedly connected to the pressure block 46, which is located above the slide groove 3 43. The side of the pressure block 46 facing the slide groove 3 43 has a groove 2 47, and the cross-sectional shape of the groove 2 47 along the width direction of the transmission platform 2 40 is arc-shaped.

[0044] When the silencing pipe after drilling is rotated to the side of the discharge assembly 4, the output end of the hydraulic telescopic cylinder 41 is extended, the transfer table 40 moves to the side of the fixed assembly 3, so that the slide 3 43 receives the silencing pipe, the output end of the hydraulic telescopic cylinder 44 is retracted, so that the pressure block 46 descends to press the silencing pipe, and the output end of the hydraulic telescopic cylinder 41 is retracted again. With the cooperation of the pressure block 46 and the slide 3 43, the silencing pipe on the round pipe 19 is moved out of the fixed assembly 3.

[0045] In this embodiment, the output end of the hydraulic telescopic cylinder 6 is extended, causing the transmission platform 5 to move towards the fixed component 3. This causes a silencer tube on the slide 8 near the fixed component 3 to approach the round tube 19. At this time, the side of the transmission platform 5 near the fixed component 3 abuts against the side of the connecting plate 37. The output end of the linear motor 9 is then moved towards the fixed component 3, and the baffle 10 pushes the silencer tube on the slide 8 to fit onto the round tube 19. Subsequently, the output end of the hydraulic telescopic cylinder 6 is retracted again, and the transmission platform 5 moves away from the fixed component 3 to prevent the fixed component 3 from colliding with the transmission platform 5 when rotating the round tube 19.

[0046] Start the rotary motor 29 to rotate the disc 27, so that the side of the slide groove 28 away from the center of the disc 27 contacts the ball 25. Under the action of the slide groove 28, the ball 25 causes the support rod 24 to extend radially along the cavity 3 22. The side of the support rod 24 away from the cavity 3 22 supports and fixes the muffler tube sleeved on the round tube 19, so that the muffler tube and the round tube 19 are concentrically set.

[0047] Start the swing motor 17. The swing motor 17 can rotate at a fixed angle through the output shaft, thereby causing the gear 2 18 to drive the gear 16 to rotate at a fixed angle, thereby causing the round tube 19 to drive the muffler to rotate. According to actual needs, control the hydraulic telescopic cylinder 2 32 and the hydraulic telescopic cylinder 36 to extend. Start the rotary cylinder 1 34 and the rotary cylinder 2 38, so that the drill bit 1 35 and the drill bit 2 39 drill holes in the muffler. At the same time, the drill bit 1 35 and the drill bit 2 39 are staggered from the support rod 24 to prevent the drill bit 1 35 and the drill bit 2 39 from colliding with the support rod 24 when drilling.

[0048] After drilling is completed, the output ends of hydraulic telescopic cylinder 2 (32) and hydraulic telescopic cylinder 3 (36) are retracted, and drill bit 1 (35) and drill bit 2 (39) are moved out of the muffler and stop rotating after resetting.

[0049] Then, control the swing motor 2 31 to drive the round tube 19 to rotate 180°, so that the silencing tube after drilling is rotated to the side of the discharge component 4. Control the output end of the hydraulic telescopic cylinder 41 to extend, and the transmission table 2 40 moves to the side of the fixed component 3, so that the chute 3 43 receives the silencing tube.

[0050] The rotary motor 29 rotates in the opposite direction to make the side of the slide groove 28 closest to the center of the disk 27 contact the ball 25. Under the elastic action of the spring 26, the support rod 24 retracts into the groove 20 and does not support the silencer tube.

[0051] The output end of the hydraulic telescopic cylinder 44 is retracted, causing the pressure block 46 to descend and press the muffler tube. The output end of the hydraulic telescopic cylinder 41 is retracted again. With the cooperation of the pressure block 46 and the slide groove 43, the muffler tube on the round tube 19 is moved out from the fixed component 3. After it is moved out, the output end of the hydraulic telescopic cylinder 44 is extended to prepare for the removal of the next muffler tube.

[0052] While the discharge component 4 removes the silencer tube, the feeding component 2 puts the silencer tube onto a round tube 19 on the fixed component 3 near the feeding component 2 and prepares to drill a hole, thereby improving the efficiency of drilling the silencer tube.
