Description

Technical Field

[0001] This invention relates to the field of Roots blower processing, specifically a high-efficiency special brazing equipment for Roots blowers. Background Technology

[0002] A Roots blower is a positive displacement blower that forces gas from the inlet to the outlet through two synchronously rotating figure-eight rotors. It features constant flow, high pressure, and low pulsation. The inlet is equipped with an inlet silencer, and the outlet with an outlet silencer. The inlet silencer not only reduces intake noise but also filters the air; therefore, it should be designed to be removable for easy cleaning. The outlet silencer, however, does not filter the air and is therefore designed as a single, integral component.

[0003] The outlet silencer consists of a central silencer cylinder, a sound-absorbing structure inside the silencer cylinder, and end caps at both ends of the silencer cylinder. The end caps are fixed to the silencer cylinder by welding.

[0004] When welding the outlet muffler, it is necessary to ensure that the end cap and the muffler are welded on the same axis. If there is a problem of misalignment in the welding of the end cap and the muffler, a misalignment step will be generated at the joint of the end cap and the muffler. When there is gas flow inside the outlet muffler, this misalignment step will become a whistle, generating a sharp buzzing sound at this position, which will affect the muffler's noise reduction effect.

[0005] Therefore, a high-efficiency special brazing equipment for Roots blowers is proposed to address the above problems. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0008] The first clamping assembly is used to clamp the muffler, and the first clamping assembly includes two sets of symmetrically arranged vertical plates. Each set of two vertical plates has a motor at both ends. The output end of each motor is fixedly connected to a lead screw. A threaded cylinder is sleeved on the outer ring of the lead screw. An arc-shaped first clamping plate is fixedly connected to the end of the threaded cylinder connected to the same vertical plate. The first clamping plate clamps on the outer ring of the muffler.

[0009] The second clamping assembly is used to clamp the end caps at both ends of the muffler, and the second clamping assembly includes arc-shaped clamping plates symmetrically arranged on both sides of the first clamping assembly. A hydraulic rod is connected to the back of the second clamping plate, and the cylinder of the hydraulic rod is fixed to the middle position of the first clamping plate. The welding unit is used to weld the muffler.

[0010] Preferably, each of the first clamps has a recessed portion on its inner concave surface, and multiple drive rollers are rotatably connected in each recessed portion. The drive rollers are pressed against the outer surface of the muffler and roll.

[0011] Each of the No. 2 clamps has multiple rotating rollers on its concave surface, and the rotating rollers are pressed against the outer surface of the end cap and roll.

[0012] The hydraulic rod has a welding assembly on its cylinder body. The welding assembly is located near the second clamping plate and includes a support rod. The end of the support rod extends to the welding position between the muffler and the end cap, and a welding gun is provided at the end of the support rod.

[0013] Preferably, the operating platform is provided with a top material assembly, and the top material assembly includes a lifting plate between two sets of vertical plates. The middle position of the lifting plate is provided with an arc-shaped No. 1 top plate, which is used to support the muffler. The upper surfaces of both ends of the lifting plate are provided with arc-shaped No. 2 top plates, which are used to support the end caps.

[0014] Preferably, a horizontal plate is arranged across the operating platform, and a sliding plate is symmetrically fixed to the upper surface of the horizontal plate. A sliding groove is formed on the sliding plate, and the sliding groove is slidably connected to a vertical plate.

[0015] Preferably, each of the No. 2 clamps is symmetrically threaded with two No. 1 adjusting bolts, the end of each No. 1 adjusting bolt extends into the concave position of the No. 2 clamp, and the end of each No. 1 adjusting bolt is rotatably connected to a U-shaped frame, with a rotating roller rotatably connected inside the frame.

[0016] Preferably, each of the frames has a counterweight at its bottom center.

[0017] Preferably, a rectangular frame is fixedly connected to the middle of the back side of each of the second clamping plates, and a rectangular block is slidably connected to the rectangular frame. The rectangular block is fixed to the output end of the hydraulic rod, and a second adjusting bolt is threaded onto each rectangular block, with the second adjusting bolt extending through the rectangular frame.

[0018] Preferably, a reinforcing rod is fixedly connected between the hydraulic rods connected to the same set of vertical plates;

[0019] Each of the threaded cylinders is fixedly connected to a second reinforcing rod between itself and its adjacent hydraulic rod.

[0024] 2. In this invention, after spot welding, the drive roller rotates, which in turn drives the muffler to rotate, allowing the welding gun to perform full welding. This eliminates the need to remove the muffler after spot welding and then transport it to the full welding stage, saving time and improving efficiency. It also avoids misalignment caused by the muffler or end cap colliding with foreign objects during transport after spot welding. Attached Figure Description

Detailed Implementation

[0040] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0041] Reference Figure 1 - Figure 12 A high-efficiency special brazing equipment for Roots blowers includes an operating table 1 and a welding unit. A clamping unit is provided on the operating table 1, and the clamping unit includes a first clamping component and a second clamping component.

[0042] The first clamping assembly is used to clamp the muffler 101, and the first clamping assembly includes two sets of symmetrically arranged vertical plates 2. Each set of two vertical plates 2 has a motor at both ends. The output end of each motor is fixedly connected to a lead screw 3. A threaded cylinder 4 is sleeved on the outer ring of the lead screw 3. An arc-shaped first clamping plate 5 is fixedly connected to the end of the threaded cylinder 4 connected to the same vertical plate 2. The first clamping plate 5 clamps on the outer ring of the muffler 101.

[0043] The second clamping assembly is used to clamp the end caps 102 at both ends of the muffler 101, and the second clamping assembly includes arc-shaped second clamping plates 6 symmetrically arranged on both sides of the first clamping assembly. The back of the second clamping plate 6 is connected to a hydraulic rod 7, and the cylinder of the hydraulic rod 7 is fixed to the middle position of the first clamping plate 5. The welding unit is used to weld the muffler.

[0044] In this embodiment of the invention, the clamping unit operates as follows: It drives the motors on the two sets of vertical plates 2, which in turn rotate the lead screw 3. The lead screw 3 then pushes the threaded cylinder 4 to move, and the threaded cylinder 4 pushes the first clamping plate 5 closer together. The first clamping plate 5 clamps the silencer 101. Figure 2 and Figure 4 As shown, in this embodiment, four clamping plates 5 are clamped onto the muffler 101. When the threaded cylinder 4 pushes the clamping plates 5 closer together, the clamping plates 5 also drive the hydraulic rods 7 closer together. The hydraulic rods 7 drive the clamping plates 6 connected to their output ends to move closer together and clamp the end cap 102. Figure 9 and Figure 11 As shown, in this embodiment, two adjacent second clamping plates 6 are clamped on the middle outer ring of the end cap 102; the second clamping plate 6 clamps the end cap 102, and the first clamping plate 5 clamps the muffler 101. At this time, the axis of the end cap 102 and the axis of the muffler 101 are coaxial. Then, the hydraulic rod 7 is driven, and the hydraulic rod 7 drives the two end caps 102 to approach and attach to the end face of the muffler 101 through the second clamping plates 6, as shown. Figure 12 As shown, both ends of the silencer 101 are fitted with end caps 102, forming a complete outlet silencer;

[0045] Then spot welding is performed. In this embodiment, the welding unit includes a welding gun 12 and adopts a brazing welding process. First, spot welding is performed at the welding positions of the end cap 102 and the muffler 101. For example, spot welding is performed at two positions. The end cap 102 and the muffler 101 are fixed together in advance. Then, the first clamping assembly and the second clamping assembly are retracted and reset. The outlet muffler is removed from the welding unit and transported to the next environment for full welding.

[0046] This high-efficiency Roots blower special brazing equipment, through the cooperation of clamping component No. 1 and clamping component No. 2, achieves coaxial clamping of silencer 101 and end cover 102, ensuring precise fit between silencer 101 and end cover 102, avoiding misalignment steps at the joint of silencer 101 and end cover 102, thereby ensuring the noise reduction effect of the outlet silencer;

[0047] Furthermore, the No. 1 clamping plate 5 and the No. 2 clamping plate 6 are both arc-shaped, which can hold silencers 101 and end caps 102 of different sizes, making them suitable for processing outlet silencers of different specifications and sizes, and providing high flexibility.

[0048] Reference Figure 8 Each of the first clamping plates 5 has a recess 8 on its inner concave surface, and multiple drive rollers 9 are rotatably connected in each recess 8. The drive rollers 9 are pressed against the outer surface of the muffler 101 and roll.

[0049] Each of the second clamping plates 6 has a plurality of rotating rollers 10 on its concave surface, and the rotating rollers 10 are pressed against the outer surface of the end cap 102 and roll.

[0050] The cylinder of the hydraulic rod 7 is provided with a welding assembly. The welding assembly is located near the second clamping plate 6. The welding assembly includes a support rod 11. The end of the support rod 11 extends to the welding position between the muffler 101 and the end cap 102. A welding gun 12 is provided at the end of the support rod 11.

[0051] The recess 8 contains drive rollers 9, each of which can be connected to a servo motor. The servo motor drives the drive roller 9 to rotate. Alternatively, each drive roller 9 in the same recess 8 can be connected to a sprocket at its end. Multiple sprockets are connected by a chain, and with the help of a reduction motor, all drive rollers 9 in the same recess 8 can rotate synchronously. The rotation of the drive roller 9 drives the muffler 101 to rotate. After the second clamping assembly fits the two end caps 102 onto the ends of the muffler 101 and performs spot welding, the end caps 102 and the muffler 101 are pre-fixed together. Then, the drive roller 9 is operated to rotate, and the drive roller 9 rubs the muffler 101 to rotate. The muffler 101 will drive the end caps 102 to rotate synchronously. Since the end caps 102 are pressed against the second clamping plate 6 by the rotating roller 10, the drive roller 9 rotates the muffler 101. Therefore, the end cap 102 can also rotate smoothly. During the synchronous rotation of the muffler 101 and the end cap 102, the welding gun 12 is driven. The welding gun 12 is used for full welding of the muffler 101 and the end cap 102, and it is also welded by brazing. Specifically, in this embodiment, two welding guns 12 are arranged in a circumferential array around each end cap 102. Therefore, the drive roller 9 only needs to drive the muffler 101 to rotate 180 degrees counterclockwise or clockwise. It is not necessary to remove it after spot welding and then transport it to the full welding stage, which saves time and improves efficiency. At the same time, it can also avoid the muffler 101 or the end cap 102 colliding with foreign objects when transporting the muffler 101 and the end cap 102 after spot welding, which would cause misalignment.

[0052] Reference Figure 1 - Figure 6 The operating platform 1 is equipped with a top material assembly, which includes a lifting plate 13 between two sets of vertical plates 2. The lifting plate 13 has an arc-shaped first top plate 14 in the middle position, which is used to support the muffler 101. The upper surfaces of both ends of the lifting plate 13 are equipped with arc-shaped second top plates 15, which are used to support the end cap 102.

[0053] The top assembly is used to pre-support the muffler 101 and the end cap 102. The first clamping assembly and the second clamping assembly are retracted and reset to make room for the muffler 101 and the end cap 102. Specifically, the muffler 101 is placed on the first top plate 14 and the end cap 102 is placed on the second top plate 15. Then, the first clamping assembly and the second clamping assembly are driven to clamp the muffler 101 and the end cap 102 coaxially, respectively. This design eliminates the need for operators to continuously lift the heavy muffler 101. The muffler 101 is hoisted onto the first top plate 14 by the lifting device and then removed.

[0054] In this embodiment, the top material assembly also includes a hydraulic cylinder 16 located below the lifting plate 13. The hydraulic cylinder 16 can drive the lifting plate 13 to move up and down. After the first clamping assembly and the second clamping assembly clamp the muffler 101 and the end cover 102 respectively, the hydraulic cylinder 16 drives the lifting plate 13 to move down, the first top plate 14 disengages from the muffler 101, and the second top plate 15 disengages from the end cover 102. When the hydraulic rod 7 drives the end cover 102 to move towards the end of the muffler 101, it is to prevent the outer flange of the end cover 102 from interfering with the second top plate 15 and hindering the movement of the end cover 102.

[0055] Reference Figure 1 - Figure 6 A horizontal plate is installed across the operating table 1. A sliding plate 17 is symmetrically fixed to the upper surface of the horizontal plate. A sliding groove is opened on the sliding plate 17, and the sliding groove is slidably connected to the vertical plate 2.

[0056] Considering that there are various specifications of the export silencers, when the travel distance of the screw 3 driving the threaded cylinder 4 is insufficient to effectively clamp the silencer cylinder 101 on the first clamping plate 5, the two vertical plates 2 in each group can be driven to move synchronously. Specifically, a screw is provided in the slide groove, and the screw is threadedly connected to the bottom of the vertical plate 2. The bottom of the vertical plate 2 is slidably connected in the slide groove. The screw can be rotated manually or driven by an external motor to achieve synchronous movement of the two vertical plates 2 in the same group. The threads on the screw are symmetrically arranged, which can drive the two groups of vertical plates 2 to move synchronously in opposite directions, thereby adjusting the effective travel distance of the second clamping plate 6, and thus clamping silencers 101 of different specifications, with high flexibility.

[0057] Reference Figure 9 and Figure 11 Each of the No. 2 clamping plates 6 is symmetrically threaded with two No. 1 adjusting bolts 18. The end of each No. 1 adjusting bolt 18 extends into the recessed position of the No. 2 clamping plate 6, and the end of each No. 1 adjusting bolt 18 is rotatably connected to a U-shaped frame 19. A rotating roller 10 is rotatably connected inside the frame 19.

[0058] The No. 1 adjusting bolt 18, in conjunction with the rotating roller 10, is also adapted to different specifications of outlet silencers, specifically to end caps 102 of different sizes. By rotating the No. 1 adjusting bolt 18, the distance between the rotating roller 10 and the concave part of the No. 2 clamping plate 6 is adjusted, thereby clamping end caps 102 with different outer diameters, and it has high flexibility.

[0059] Reference Figure 13 and Figure 14 Each of the frame bodies 19 is provided with a counterweight block 20 at its middle bottom;

[0060] The counterweight 20 is used to control the state of the rotating roller 10, so that the axis of the rotating roller 10 is always in a horizontal state. The specific configuration block is fixed to the frame 19, so that the center of gravity of each frame 19 tends to be on the configuration block, and the frame 19 remains in a horizontal state. When rotating the first adjusting bolt 18, the frame 19 and the rotating roller 10 can always be in a horizontal state, so that the end cover 102 can be clamped quickly and effectively.

[0061] Reference Figure 9 - Figure 11 A rectangular frame 21 is fixedly connected to the middle of the back side of each of the No. 2 clamps 6. A rectangular block 22 is slidably connected to the rectangular frame 21. The rectangular block 22 is fixedly connected to the output end of the hydraulic rod 7. A No. 2 adjusting bolt 23 is threadedly connected to each rectangular block 22. The No. 2 adjusting bolt 23 extends through the rectangular frame 21.

[0062] The rectangular frame 21, in conjunction with the second adjusting bolt 23, is used to further extend the travel range of the second clamping plate 6. Specifically, rotating the second adjusting bolt 23 causes the rectangular block 22 to move relative to the rectangular frame 21, which in turn causes the rectangular frame 21 to move the second clamping plate 6, thereby adjusting the travel range of the second clamping plate 6 and enabling it to hold more end caps 102 of different sizes.

[0063] Reference Figure 1 and Figure 8 A first reinforcing rod 24 is fixedly connected between the hydraulic rods 7 connected to the same set of vertical plates; a second reinforcing rod 25 is fixedly connected between each of the threaded cylinders 4 and its adjacent hydraulic rod 7.

[0064] The first reinforcing rod 24 is provided to enhance the connection stability between the hydraulic rod 7 and the first clamping plate 5, and to improve the overall strength and stability of the clamping unit. The second reinforcing rod 25 is provided for the same purpose. The second reinforcing rod 25 is inclined between the threaded cylinder 4 and the hydraulic rod 7 to improve the stability of the output end of the hydraulic rod 7. Multiple crossbars 26 are also provided between the two first clamping plates 5 on the same side to enhance the overall strength of the clamping unit and enable it to hold the heavy outlet silencer.

[0065] Reference Figure 9 The outer surface of the handle of each welding gun 12 is threaded to the end of the support rod 11; rotate the welding gun 12 to adjust the distance between the end of the welding gun 12 and the weld seam to ensure welding quality.

[0066] Reference Figure 4 and Figure 5 Each of the second top plates 15 is provided with a magnetic plate on its upper surface. The magnetic plate is used to attract the outer ring of the end cap 102. The magnetic plate is used to attract the end cap 102. After the end cap 102 is placed on the second top plate 15, the magnetic plate attracts the end cap 102 and stabilizes the end cap 102 to prevent the end cap 102 from swinging on the upper surface of the second top plate 15 and affecting the clamping of the second clamping plate 6.

[0067] Working principle: The motors on the two sets of vertical plates 2 drive the lead screw 3 to rotate, which in turn pushes the threaded cylinder 4 to move. The threaded cylinder 4 pushes the first clamping plate 5 closer together, and the first clamping plate 5 clamps the silencer 101. Figure 2 and Figure 4 As shown, in this embodiment, four clamping plates 5 are clamped onto the muffler 101. When the threaded cylinder 4 pushes the clamping plates 5 closer together, the clamping plates 5 also drive the hydraulic rods 7 closer together. The hydraulic rods 7 drive the clamping plates 6 connected to their output ends to move closer together and clamp the end cap 102. Figure 9 and Figure 11 As shown, in this embodiment, two adjacent second clamping plates 6 are clamped on the middle outer ring of the end cap 102; the second clamping plate 6 clamps the end cap 102, and the first clamping plate 5 clamps the muffler 101. At this time, the axis of the end cap 102 and the axis of the muffler 101 are coaxial. Then, the hydraulic rod 7 is driven, and the hydraulic rod 7 drives the two end caps 102 to approach and attach to the end face of the muffler 101 through the second clamping plates 6, as shown. Figure 12 As shown, both ends of the silencer 101 are fitted with end caps 102, forming a complete outlet silencer. Then, spot welding is performed, and then the drive roller 9 rotates, which can drive the silencer 101 to rotate. After the second clamping assembly fits the two end caps 102 at the ends of the silencer 101, spot welding is performed. At this time, the end caps 102 and the silencer 101 are pre-fixed together. Then, the drive roller 9 is operated to rotate, and the drive roller 9 rubs the silencer 101 to rotate. The silencer 101 will drive the end caps 102 to rotate synchronously. Since the end caps 102 are pressed on the second clamping plate 6 by the rotating roller 10, the end caps 102 can also rotate smoothly. During the synchronous rotation of the silencer 101 and the end caps 102, the welding gun 12 is driven. The welding gun 12 is used for full welding of the silencer 101 and the end caps 102.

[0068] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
