Description

Technical Field

[0001] This utility model relates to the field of muffler housing processing technology, specifically a jig for processing muffler housing with a flipping structure. Background Technology

[0002] The muffler housing is the main structure of the muffler, usually made of metal materials (such as titanium alloy, aluminum alloy or stainless steel). Its main function is to house the internal noise reduction components and withstand the impact of high temperature and high pressure combustion gases. The muffler housing needs to be processed by a processing device during production.

[0003] Existing muffler housing processing equipment typically places the muffler housing on a processing table and clamps it in a specific position using a clamping device. This clamping and positioning allows for stable processing of the muffler housing. For example:

[0004] CN220312264U discloses a welding and fixing fixture for automotive mufflers, including an angle adjustment assembly and an operating table assembly. The angle adjustment assembly includes a vertical plate, a base plate, a circular through-slot, a turntable, and a drive device; the operating table assembly includes a connecting rod, a connecting plate, and a worktable. The muffler is fixed to the movable fixture by adjusting a handwheel. The handwheel is secured by tightening a limit bolt to prevent it from rotating back. When the muffler angle needs adjustment, the drive motor is started, the meshing gear drives the second rotating shaft to rotate, the second rotating shaft drives the turntable to rotate, and the turntable drives the connecting rod to rotate; then the connecting rod drives the connecting plate to rotate, thereby rotating the worktable and adjusting the muffler angle, facilitating multi-directional welding of the muffler. The outer ring of the turntable's rollers cooperates with an annular slide rail to provide auxiliary support to the turntable during rotation, thus making the turntable more stable.

[0005] The existing technical solutions have the following drawbacks: during the clamping process of the muffler housing, due to the different dimensions and lengths of the housing, it is not convenient to adjust the clamping components according to the requirements. At the same time, processing can only be carried out in one direction, making it inconvenient to flip the clamping components to improve processing efficiency. Therefore, this utility model provides a clamp for processing muffler housing with a flipping structure to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this utility model is to provide a jig for processing muffler housings with a flipping structure, so as to solve the problems mentioned in the background art, where the size and length of the muffler housings are different, making it inconvenient to adjust the clamping components according to the requirements, and the processing can only be carried out in one direction, making it inconvenient to flip the clamping components to improve processing efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a jig for machining a muffler housing with a flipping structure, comprising: a machining panel, and a first connecting outer plate and a second connecting outer plate respectively disposed on the upper side of the machining panel, and further comprising:

[0008] The outer side of the processing panel is connected to a first motor, and the output end of the first motor is provided with a connecting rod. The middle part of the processing panel is fixed with a mounting plate by bolts, and the upper side of the mounting plate is connected to a first electric telescopic rod. The upper side of the first electric telescopic rod is provided with a stable support plate.

[0009] The second connecting outer plate has a limiting groove inside, and an annular disk is installed inside the limiting groove. A positioning connecting rod is provided at an equal angle at the outer end of the annular disk. A positioning hole is provided inside the positioning connecting rod, and a threaded rod is installed inside the positioning hole. A clamping component is also provided on the outer side of the positioning connecting rod.

[0010] As a preferred embodiment of this utility model, the connecting rod is connected to the second connecting outer plate by a thread, and a second motor is provided on the outer side of both the second connecting outer plate and the first connecting outer plate, and the output end of the second motor is connected to a connecting plate.

[0011] As a preferred technical solution of this utility model, the connecting disc and the connecting block on the outer surface of the annular disc are connected by meshing, and the annular disc is slidably connected to the second connecting outer plate and the first connecting outer plate respectively through a columnar structure.

[0012] As a preferred embodiment of the present invention, the clamping assembly includes a second electric telescopic rod disposed on the outer side of the annular disk, and a first clamping block is connected to the end of the second electric telescopic rod. A second clamping block is disposed on the outer end of the first clamping block. A connecting collar is installed on the outer surface of the positioning connecting rod, and a limiting rod is disposed on the outer end of the connecting collar.

[0013] As a preferred embodiment of this utility model, the connecting collar and the positioning connecting rod are connected in a sliding manner, and the positioning holes are opened at equal intervals inside the positioning connecting rod.

[0014] As a preferred embodiment of this utility model, the limiting rod, the connecting collar, and the second clamping block are all connected by rotation.

[0015] As a preferred embodiment of this utility model, the second clamping block is symmetrically arranged at the outer end of the first clamping block, and the first clamping block and the second clamping block have an arc-shaped structure.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the muffler housing processing jig with a flipping structure, through the setting of the clamping component, adjusts and clamps the muffler housing to a limited position, and at the same time, the angle of the clamping component is adjusted under the rotation of the connecting plate, which facilitates the flipping and processing of the clamped muffler housing, thus improving the processing efficiency.

[0017] The muffler shell is clamped through by the first clamping block. The connecting collar and the positioning connecting rod are connected in a sliding manner. By sliding the connecting collar on the outer surface of the positioning connecting rod, the limiting rod, the connecting collar and the second clamping block are connected in a rotating manner. The rotation of the second clamping block adjusts the clamping arc of the first clamping block and the second clamping block. The positioning holes are equally spaced inside the positioning connecting rod, thereby adjusting and limiting the second clamping block and increasing the stability of clamping the muffler shell.

[0018] The connecting rod is connected to the second connecting outer plate by means of threads. According to the length of the muffler shell, the first motor is started to drive the connecting rod at the output end to rotate in the processing panel. The rotation of the connecting rod moves the second connecting outer plate, which is convenient to adjust and clamp according to the length of the muffler shell.

[0019] The connecting disc is connected to the connecting block on the outer surface of the annular disc by meshing. By starting the second motor, the connecting disc at the output end is rotated. When the connecting disc rotates, it rotates with the annular disc through the connecting block, causing the annular disc to rotate inside the first connecting outer plate and the second connecting outer plate respectively, clamping and flipping the muffler shell for easy processing.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 This utility model provides a technical solution: a jig for processing a muffler housing with a flipping structure, including a processing panel 1, a first motor 2, a connecting rod 3, a mounting plate 4, a first electric telescopic rod 5, a stabilizing support plate 6, a first connecting outer plate 7, a second motor 8, a connecting disc 9, an annular disc 10, a connecting block 11, a second electric telescopic rod 12, a positioning connecting rod 13, a positioning hole 14, a connecting collar 15, a limiting rod 16, a first clamping block 17, a second clamping block 18, a threaded rod 19, a second connecting outer plate 20, and a limiting groove 21.

[0029] Working principle: When using this fixture for machining the muffler housing with a flipping structure, firstly as follows... Figure 4 , Figure 5 and Figure 6In this process, a first connecting outer plate 7 and a second connecting outer plate 20 are provided on the upper side of the processing panel 1. The cylindrical muffler shell is inserted into the interior of the first connecting outer plate 7. At the same time, a clamping assembly is provided at an equal angle on the outer end of the first connecting outer plate 7. The clamping assembly includes a second electric telescopic rod 12 provided on the outer side of the annular disk 10, and a first clamping block 17 is connected to the end of the second electric telescopic rod 12. A second clamping block 18 is provided on the outer end of the first clamping block 17. A connecting collar 15 is installed on the outer surface of the positioning connecting rod 13, and a limiting rod 16 is provided on the outer end of the connecting collar 15. When the second electric telescopic rod 12 is activated, the second electric telescopic rod 12 drives the first clamping block 17 and the outer fixed positioning connecting rod 13 to slide inside the annular disk 10. The muffler shell is clamped through by the first clamping block 17, and the connecting collar 15 and the first clamping block 17 are clamped through the muffler shell. The positioning connecting rod 13 is connected in a sliding manner. By sliding the connecting collar 15 on the outer surface of the positioning connecting rod 13, the limiting rod 16 is connected to the connecting collar 15 and the second clamping block 18 in a rotating manner. At this time, the rotation of the limiting rod 16 causes the second clamping block 18 to rotate at the outer end of the first clamping block 17. The second clamping block 18 is symmetrically arranged at the outer end of the first clamping block 17, and the first clamping block 17 and the second clamping block 18 have an arc-shaped structure. By rotating the second clamping block 18, the clamping arc of the first clamping block 17 and the second clamping block 18 is adjusted. The positioning holes 14 are equally spaced inside the positioning connecting rod 13. When the second clamping block 18 is adjusted to a suitable angle, the threaded rod 19 is rotated and passed through the suitable positioning hole 14, thereby adjusting and limiting the second clamping block 18, increasing the stability of clamping the muffler shell.

[0030] Specific examples Figure 1 , Figure 2 and Figure 3In the process panel 1, a mounting plate 4 is bolted to the center, and a first electric telescopic rod 5 is connected to the upper side of the mounting plate 4. A stabilizing support plate 6 is provided on the upper side of the first electric telescopic rod 5. When the muffler housing is placed on the upper end of the stabilizing support plate 6, the stabilizing support plate 6 is moved upward by activating the first electric telescopic rod 5, adjusting the muffler housing to a suitable support height. A first motor 2 is connected to the outer side of the process panel 1, and a connecting rod 3 is provided at the output end of the first motor 2. The connecting rod 3 is threaded to the second connecting outer plate 20. The two devices are connected in a manner that, based on the length of the muffler housing, the first motor 2 is started, causing the connecting rod 3 at the output end to rotate within the processing panel 1. The rotation of the connecting rod 3 moves the second connecting outer plate 20, facilitating adjustment and clamping according to the length of the muffler housing. Simultaneously, the second connecting outer plate 20 has a limiting groove 21 inside, and an annular disk 10 is installed inside the limiting groove 21. A positioning connecting rod 13 is provided at an equal angle at the outer end of the annular disk 10, and a positioning hole 14 is provided inside the positioning connecting rod 13. Furthermore, a threaded rod 19 is installed inside the positioning hole 14, and a clamping assembly is also provided on the outside of the positioning connecting rod 13. In the same way as above, the clamping assembly clamps and limits the other end of the muffler shell. Since a second motor 8 is provided on the outside of the first connecting outer plate 7, and the output end of the second motor 8 is connected to the connecting plate 9, and a limiting groove 21 is also opened inside the first connecting outer plate 7, and an annular disk 10 is installed inside the limiting groove 21, and the annular disk 10 is slidably connected to the first connecting outer plate 7 through a columnar structure. The connecting plate 9 and the connecting block 11 on the outer surface of the annular disk 10 are connected by meshing. By starting the second motor 8, the second motor 8 drives the connecting plate 9 at the output end to rotate. When the connecting plate 9 rotates, the connecting plate 9 rotates with the annular disk 10 through the connecting block 11, so that the annular disk 10 rotates inside the first connecting outer plate 7 and the second connecting outer plate 20 respectively, clamping and flipping the muffler shell for easy processing. This is the usage method of the muffler shell processing fixture with a flipping structure.
