[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] One of the main functions of a vehicle muffler is to reduce exhaust noise to reduce noise pollution to the environment. The muffler should be manufactured according to the approved drawings and technical documents of the prescribed procedures and meet the requirements of the standard. This includes appearance quality, dimensional tolerance and material, etc. to ensure that the muffler can achieve the effect of reducing noise. The performance test items of the muffler include aerodynamic performance test and noise elimination performance test, which ensure that the muffler can effectively reduce noise in actual use and will not cause excessive resistance loss to the airflow. However, the machining precision of the muffler shell directly affects its aerodynamic performance and noise elimination performance. For example, poor welding can cause leakage problems, affecting its air tightness; and the size, shape, whether there is burr, whether there is deformation, etc. of the product will also have a very great influence on the performance and quality of the final product. Therefore, during the production of the muffler, the tool detection of each machined muffler shell needs to be detected and light etching is marked. The production process of the prior art product mainly includes: product machining, tool detection, air tightness detection, laser marking and warehousing, and the tool detection and laser marking are two different processes, and the tool and marking tooling are configured respectively, which not only needs to increase the tooling cost, personnel allocation and manual working hours, but also increases the risk of abrasion and collision deformation of thin-walled products during process transfer taking and placing.

[0038] Therefore, the utility model provides a kind of automobile muffler shell laser marking and detection integrated device, on device structure can meet the detection requirement and can meet laser marking clamping, adjust process layout simultaneously, make laser marking and tool detection complete in sequence, save personnel and working hours, improve production efficiency.

[0039] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the utility model will be further described in detail below with reference to the drawings and specific embodiments.

[0040] Reference Figures 1 to 15As shown, the present invention provides an integrated laser engraving and inspection device for automobile muffler housings, comprising a device platform 1. The device platform 1 serves as the foundation of the entire device and has a bearing platform for supporting other components. A first support 3 and a second support 9 are fixedly connected to the device platform 1 along a first direction. The first support 3 and the second support 9 have the same structure and are arranged opposite to each other, forming a clamping space for placing the pipe 100 to be inspected. A clamping inspection gauge 1 5 is connected to the first support 3. The first support 3 can serve as a fixed end and is fixedly connected to the clamping inspection gauge 1 5. The clamping inspection gauge 1 5 can also be flexibly connected to the first support 3 for adjustment, thereby adapting to the inspection of pipes 100 to be inspected of different specifications, or facilitating the loading of the pipes 100 to be inspected. A clamping inspection gauge 2 7 is flexibly connected to the second support 9. The clamping inspection gauge 1 5 and the clamping inspection gauge 2 7 cooperate to clamp the two ends of the pipe 100 to be inspected and perform inspection. As the movable end, the clamping detection rule 2 7 is axially slidably inserted into the first support 3 through the shaft 2 8, so that the clamping detection rule 2 7 can linearly approach or move away from the clamping detection rule 1 5 along the first direction, and can also rotate circumferentially around its central axis. There is a clamp 2 14 between the clamping detection rule 2 7 and the second support 9 to limit the axial movement of the clamping detection rule 2 7. The clamp 2 14 is provided with a slot 1 that allows the clamping detection rule 2 7 to move within the tolerance range, and a slot 2 that fixes the clamping detection rule 2 7 in the axial direction. Four third supports 6 are fixedly connected to the device platform 1 on both sides of the middle of the first support 3 and the second support 9. The four third supports 6 are opposite to each other in pairs, that is, two groups are arranged along the first direction, and the two third supports 6 in each group are arranged facing each other along the second direction, wherein the second direction is perpendicular to the first direction. A circumferential side inspection fixture 16 is fixedly connected to the opposite side of the third support 6. The circumferential side inspection fixture 16 contacts and detects the external dimensions of the pipe 100 to be inspected from both sides.

[0041] In a specific embodiment, the peripheral inspection fixture 16 is detachably fixed to the third support 6 by bolts, and can be replaced and adjusted in position according to inspection requirements.

[0042] In some optional embodiments, the circumferential inspection fixture 16 is a contact displacement sensor that is detachably mounted on the inner side of the third support 6. The contact displacement sensor senses the shape and position of the object by contacting the surface of the object, thereby measuring the size and position information of the object. It is usually composed of a measuring head and a signal processor. The part of the measuring head that contacts the object is usually composed of a contact and a spring. When the contact contacts the surface of the object, the spring is compressed, and the position and compression of the contact can be measured. The signal processor converts the signal collected by the measuring head into a digital signal, thereby achieving accurate measurement of the circumferential size and position of the pipe 100 to be inspected.

[0043] It should be understood that the circumferential side gauge 16 can be a different type of sensor in a specific embodiment, such as a proximity contact sensor, a pressure line contact sensor, etc., for example, when a proximity contact sensor is used, when an object approaches the sensor, the object will cause the electric field or magnetic field inside the sensor to change. The sensor can detect these changes, thereby determining whether the object is close to the sensor.

[0044] In a specific embodiment, the clamping detection gauge two 7 is rotatably and axially slidably arranged in the second support 9, and a detection movable pin 13 is fixedly connected to the shaft two 8 of the second support 9, which can be clamped into the clamping groove one and the clamping groove two with the rotation of the shaft two 8.

[0045] In some alternative embodiments, the clamping groove two is arranged at the bottom of the clamping groove one, and the two form a T-shaped groove.

[0046] In some alternative embodiments, the clamp two 14 can be detachably fixed on the second support 9 on one side of the shaft two 8.

[0047] It should be understood that in actual application, the clamping groove one and the clamping groove two can be combined into one, designed as a T-shaped structure on the clamp two 14 in the embodiment, as shown in Figure 6 It can also be designed on two clamps respectively, for example, two clamps are arranged on both sides of the shaft two 8, and the clamping groove one and the clamping groove two are arranged on the two clamps respectively.

[0048] In a specific embodiment, the clamping detection gauge one 5 is rotatably and axially slidably arranged in the first support 3, and a fixed pin 11 is fixedly connected to the shaft one 4 of the clamping detection gauge one 5, which is connected to the first support 3. The first support 3 is fixedly connected with a clamp one 12, and the clamp one 12 is provided with a U-shaped groove allowing the fixed pin 11 to be clamped into.

[0049] In a specific embodiment, the clamping detection gauge one 5 and the clamping detection gauge two 7 are respectively fixedly connected with an operating handle at one end away from each other, as shown in Figure 1 The operating handle one 2 is arranged at the distal end of the clamping detection gauge one 5, and the operating handle two 10 is arranged at the distal end of the clamping detection gauge two 7.

[0050] In some alternative embodiments, the device platform 1 is further provided with an end detection gauge 15, which is used for vertically inserting into the pipe to be detected 100 to detect the spinning height of both ends, so as to ensure that the spinning height of both ends of the pipe meets the requirements.

[0051] In some optional embodiments, a plug gauge 19 is also inserted on the device platform 1, which is used to detect the skewness of the pipe end face of the pipe to be detected 100, to ensure that the pipe end face is flat and has no skewness.

[0052] In some optional embodiments, a plug gauge 19 is also inserted on the device platform 1, which is used to detect the skewness of the pipe end face of the pipe to be detected 100, to ensure that the pipe end face is flat and has no skewness.
