Description

Technical Field

[0001] This utility model relates to the field of silencer technology, specifically to a silencer pipe flange welding device. Background Technology

[0002] As an important noise control device, the muffler's origins can be traced back to the early 20th century with the widespread adoption of internal combustion engines and industrial equipment. Early mufflers primarily employed resistive structures, using Helmholtz resonators or expansion chambers to cancel out sound wave reflections, but these suffered from poor low-frequency performance and high airflow resistance. In the mid-20th century, with advancements in materials science, sound-absorbing materials, such as glass fiber, were widely used in resistive mufflers, significantly broadening the mid-to-high frequency noise reduction band.

[0003] However, the current manufacturing process of silencers requires welding of pipe flanges. When welding in large quantities, molds can be used to easily limit the position of the pipe flanges. However, when limiting the position of a small number of different styles of pipe flanges, changing the molds is time-consuming and laborious, which affects the welding efficiency of the flanges and pipes. Utility Model Content

[0004] The purpose of this invention is to provide a welding device for silencer pipe fittings flanges to address the shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressing assembly is included, the pressing assembly including a disc connected to a fixed plate via a torsion spring, a handle is provided at one end of the disc, the handle is snapped into the fixed plate via a snap-fit ​​structure, the torsion spring is in a stored state when the handle is snapped into the fixed plate, and a clamping rod is also provided on the disc, the clamping rod can be driven to abut against the fixed plate when the torsion spring is released.

[0006] Furthermore, the bottom of the fixing plate is provided with a mounting plate, the mounting plate is rotatably connected to a workbench, the bottom of the workbench is provided with a mounting box, the mounting box is provided with a motor, the output end of the motor is connected to the mounting plate, and the bottom of the mounting box is provided with four fixing seats.

[0007] Furthermore, a first support member is provided on the top of the fixed plate, and the first support member is fixedly connected to a connecting plate. An electric slide rail is provided on the connecting plate, and a drive source is provided near the top of the connecting plate. The drive source can drive the electric slide rail to operate.

[0008] Furthermore, a sliding member is provided on the electric slide rail, and a connecting rod is fixedly provided on the sliding member. A welding head is provided at the end of the connecting rod away from the sliding member.

[0009] Furthermore, a limiting baffle is provided on the top of the workbench, and the limiting baffle corresponds to the position of the mounting plate.

[0010] Furthermore, a second support is provided on the top of the workbench, a power distribution box is provided on the second support, and an alarm light is provided on the top of the second support.

[0011] Compared with the prior art, the muffler pipe flange welding device provided by this utility model has a limit groove on the fixed plate to accommodate different types of pipe flanges. When welding different types of pipe flanges, the device can limit the welding of key flanges of different types by changing the fixed plate with different limit grooves. However, when welding a small number of pipe flanges, the pipe flange can be placed on the fixed plate, and then the handle can be engaged with the fixed plate, causing the torsion spring to be released, driving the disc to rotate, which in turn drives the handle to rotate and simultaneously drives the clamping rod to advance. The handle rotates to engage the clamping rod with the critical flange, thus limiting the flange's position. After welding the flange, the handle can be rotated to rotate the disc, causing the torsion spring to store force and move the clamping rod. This removes the clamping rod from the flange, freeing it from its position and allowing the welded flange to be removed. When the clamping rod is no longer needed, it can be released from the fixing plate by rotating the handle, and the handle can be locked in place by a snap-fit ​​mechanism.

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] Please see Figure 1-4 The present invention provides a muffler pipe flange welding device, including a pressing assembly 1. The pressing assembly 1 includes a disc 102 connected to a fixed plate 101 by a torsion spring. One end of the disc 102 is provided with a handle 103. The handle 103 is snapped into the fixed plate 101 by a snap-fit ​​structure. When the handle 103 is snapped into the fixed plate 101, the torsion spring is in a stored state. The disc 102 is also provided with a clamping rod 104. When the torsion spring is released, it can drive the clamping rod 104 to abut against the fixed plate 101.

[0020] In use, the fixed plate 101 is equipped with limit grooves to accommodate different types of pipe flanges. When welding different styles of pipe flanges, the fixed plate 101 with different limit grooves can be replaced to limit the welding of different styles of critical flanges. However, when welding a small number of pipe flanges, the pipe flange can be placed on the fixed plate 101, and then the handle 103 is engaged with the fixed plate 101, causing the torsion spring to release and the disc 102 to rotate, which in turn rotates the handle 103. Simultaneously, the clamping rod 104 rotates, causing the clamping rod 104 to engage with the handle. The flanges are clamped together to limit their position. After welding the flanges, the handle 103 can be rotated to rotate the disc 102, causing the torsion spring to store force and move the clamping rod 104. This removes the clamping rod 104 from the flanges, freeing them from being limited. The welded flanges can then be removed. When the clamping rod 104 is no longer needed to hold the flanges, the handle 103 can be rotated to release it from the fixing plate 101, and the handle 103 can be locked in place by a snap-fit ​​structure.

[0021] Preferably, the bottom of the fixing plate 101 is provided with a mounting plate 2, which is rotatably connected to a workbench 3. The bottom of the workbench 3 is provided with a mounting box 4, which contains a motor. The output end of the motor is connected to the mounting plate 2. The bottom of the mounting box 4 is provided with four fixing seats 5.

[0022] Preferably, a first support member 6 is provided on the top of the fixed plate 101. The first support member 6 is fixedly connected to a connecting plate 7. An electric slide rail 8 is provided on the connecting plate 7. A drive source 9 is provided on the connecting plate 7 near the top. The drive source 9 can drive the electric slide rail 8 to operate.

[0023] Preferably, a sliding member 10 is provided on the electric slide rail 8, and a connecting rod 11 is fixedly provided on the sliding member 10. A welding head 12 is provided at the end of the connecting rod 11 away from the sliding member 10. The sliding member 10 can drive the welding head 12 to move, so that the welding head can enter the welding position to perform welding, and can leave the welding area after welding, so that the welded flange fitting can be removed.

[0024] Preferably, a limiting baffle 13 is provided on the top of the workbench 3. The limiting baffle 13 corresponds to the position of the mounting plate 2. By blocking the welding joint through the limiting baffle 13, the welding slag will not splash and cause injury to the workers when welding the pipe flange.

[0025] Preferably, a second support member 14 is provided on the top of the workbench 3, a power distribution box 15 is provided on the second support member 14, and an alarm light 16 is provided on the top of the second support member 14. When the equipment malfunctions, the alarm light 16 will provide an alarm prompt.

[0026] The working principle of this utility model is as follows: By setting a limiting groove on the fixed plate 101 to accommodate different types of pipe flanges, when welding different styles of pipe flanges, the fixed plate 101 with different limiting grooves can be replaced to limit the key flanges of different styles. However, when welding a small number of pipe flanges, the pipe flange can be placed on the fixed plate 101, and then the handle 103 is engaged with the fixed plate 101, causing the torsion spring to be released, driving the disc 102 to rotate, which in turn drives the handle 103 to rotate, and at the same time drives the clamping rod 104 to rotate, so that the clamping rod 104 abuts and clamps the key flange, thus limiting the pipe flange. After the pipe flange welding is completed, the handle 103 can be rotated to drive the disc 102 to rotate. The disc 102 rotates, causing the torsion spring to store force, which drives the clamping rod 104 to move, so that the clamping rod 104 no longer abuts against the pipe flange, and the pipe flange is no longer limited. At this time, the welded pipe flange can be removed. When the clamping rod 104 is no longer needed to clamp the pipe flange, the handle 103 can be rotated to release it from the fixing plate 101, and the handle 103 can be locked in place by the snap-fit ​​structure. After the pipe flange is locked, the drive source 9 can be started to drive the electric slide rail 8 to operate, so that the sliding part 10 slides and drives the connecting rod 11 to move, so that the welding head 12 moves to the welding point to weld the pipe flange. When the equipment malfunctions, the alarm light 16 will sound an alarm.

[0027] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
