Description

Technical Field

[0001] The utility model relates to the field of automobile muffler processing, in particular to a fixing tooling for automobile muffler processing. Background Technique

[0002] An automobile muffler is mainly used to reduce the noise generated when the engine of a motor vehicle works. Its principle is that the automobile exhaust pipe consists of two pipes with different lengths. These two pipes first separate and then converge. Since the length difference between these two pipes is equal to half of the wavelength of the sound wave emitted by the automobile, when the two sound waves are superimposed, they interfere with each other and cancel each other out, weakening the sound intensity and reducing the transmitted sound, thus achieving the sound elimination effect. During the processing of automobile mufflers, fixing tooling is required to fix them. However, during the use of existing fixing tooling, most of them clamp the mufflers through a single fixing clamp. When processing automobile mufflers, the clamping effect is relatively low, resulting in insufficient fixation, inaccurate fixing positions, and the inability to fix two mufflers with different specifications and sizes at the same time, making the use of the fixing tooling more restricted. Content of the Utility Model

[0003] In order to overcome the problem that during the processing of automobile mufflers, due to mostly clamping them through a single fixing clamp, the clamping effect is relatively low when processing automobile mufflers, resulting in insufficient fixation, inaccurate fixing positions, and the inability to fix two mufflers with different specifications and sizes at the same time, making the use of the fixing tooling more restricted.

[0004] The technical solution of the utility model is: a fixing tooling for automobile muffler processing, including a bottom plate; it also includes a fixing component, an adjusting component, a protective component, legs, and a protective pad. On the opposite sides of the top end of the bottom plate, there are fixing components for fixing the muffler. On the back sides of the fixing components, there are adjusting components for adjusting the height of the fixing components. On the left and right sides of the bottom plate, there are protective components rotatably connected. At the four corners of the bottom end of the bottom plate, there are legs, and at the bottom ends of the legs, there are protective pads.

[0005] Preferably, through the installation between the fixing components, the muffler to be processed can be initially fixed. The muffler is clamped in the fixing components to prevent the muffler from shifting during the processing, which affects the processing efficiency of the muffler. At the same time, when processing a muffler with a larger specification, after the fixing components are assembled, through the cooperation of the adjusting components, ensure the stable placement of the large-specification muffler. At the same time, the adjusting components can adjust the height according to the specification height of the muffler to clamp the muffler. With the cooperation of the fixing components and the adjusting components, ensure that the fixing tooling can clamp different-sized mufflers at the same time, improving the usability of the fixing tooling.

[0006] Preferably, the fixing component includes a fixing plate, an annular bracket, a mounting ring, a support ring, a mounting tube, a mounting groove, a mounting post, and a mounting block. Two groups of fixing plates are oppositely arranged at the front and rear ends of the top of the bottom plate.

[0007] Preferably, an annular bracket is symmetrically arranged at the center of the top of the fixing plate.

When installing the fixing tooling, the mounting groove on the mounting tube is clamped with the mounting post and the mounting block, so as to install the mounting tube inside the annular bracket, and the corresponding muffler is clamped on the outer side of the mounting tube, thus facilitating the fixing of the muffler card.

[0009] Preferably, the adjusting component includes a mounting plate, a telescopic cylinder, a top plate, a rotating motor, a clamping bracket, a servo motor, a rotating shaft, a pressing plate, and a rotating bracket. Two groups of mounting plates are oppositely arranged on the front and rear sides of the top of the bottom plate, and the mounting plates are arranged on the back side of the fixing plate.

[0010] Preferably, telescopic cylinders are arranged on both the left and right sides of the top of the mounting plate. The top of the telescopic cylinder is provided with a top plate, and a rotating motor is arranged at the top of the top plate. When using the fixing tooling, the rotating motor provides the operating power.

[0011] Preferably, a clamping bracket is arranged on the opposite side of the rotating motor, and servo motors are oppositely arranged on the opposite side of the fixing plate. The top of the servo motor is provided with a rotating shaft.

[0012] Preferably, the top of the rotating shaft is rotatably connected with a pressing plate, and the pressing plate is arranged above the mounting tube. The left and right ends of the rotating shaft are connected with a rotating bracket through a rotating shaft.

[0014] 1. The muffler to be processed can be preliminarily fixed through the installation between the fixing components. The muffler is clamped within the fixing components to prevent the muffler from shifting during the processing, which affects the processing efficiency of the muffler. At the same time, when processing a muffler with a larger specification, after assembling the fixing components, through the cooperation of the adjusting components, the placement of the large-specification muffler is ensured to be stable. Meanwhile, the adjusting components can adjust the height according to the specification height of the muffler to clamp the muffler. With the cooperation of the fixing components and the adjusting components, it is ensured that the fixing tooling can clamp mufflers of different sizes simultaneously, improving the usability of the fixing tooling;

[0015] 2. The telescopic end of the telescopic cylinder drives the mounting plate to move up or down, so that the clamping frame clamps the muffler card according to mufflers of different specifications and sizes.
