Description

Technical Field

[0001] This utility model relates to the field of muffler housing inspection tools, and more specifically to a muffler housing inspection tool. Background Technology

[0002] As a key component of a vehicle's exhaust system, the muffler's housing structure directly affects its noise reduction effect, airtightness, and durability. During manufacturing, rigorous testing is required on the housing's dimensional accuracy (e.g., diameter, length, wall thickness), shape tolerances (e.g., ovality, concentricity), and key assembly features (e.g., flange flatness, threaded hole positions) to ensure product performance meets standards. Furthermore, with the automotive industry's increased emphasis on component quality control and the advancement of intelligent manufacturing, there is a pressing need for multifunctional inspection tools that integrate dimensional measurement, shape verification, and assembly feature matching.

[0003] As shown in the prior art published in CN206469793U, although the prior art includes a fixture base and a fixture base plate, its features are: a fixture base is provided in the upper center of the fixture base plate, the fixture base is lower in the front and higher in the back, the upper end of the fixture base is open and a measuring groove is provided at the upper end of the fixture base opening, several measuring reference plates are provided on the upper part of the fixture base in a front-to-back direction and placed side by side, and a side clamping set is fixed on the fixture base plate on the left and right sides of the fixture base, and the clamping end of the side clamping set is provided with a side pressure edge ring. However, the positioning method of this prior art is relatively simple, with only a single clamp for side fixing, which results in poor stability of the muffler housing and easy loosening and shaking. Utility Model Content

[0004] To overcome the aforementioned deficiencies in the prior art, this utility model provides a muffler housing inspection fixture. The fixture uses a hole mechanism to engage the holes on the muffler housing, a first lateral positioning structure and a second lateral positioning mechanism to level and align both ends of the muffler housing, and a detection block mechanism to press and fix both ends of the muffler housing. This multi-directional positioning ensures the assembly accuracy of the muffler housing, thereby improving the accuracy and stability of subsequent welding of the muffler housing and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a muffler housing inspection fixture, including an inspection fixture component disposed on the top of a base plate for fixing the muffler housing;

[0006] The fixture includes a support mechanism for supporting the muffler housing in a mirror distribution, two sets of fixture hole mechanisms for positioning the muffler housing, a first lateral positioning mechanism and a second lateral positioning mechanism for laterally positioning the muffler housing, and two sets of detection block mechanisms respectively placed outside the two ends of the muffler housing.

[0007] The gauge hole mechanism is used to position the holes opened on the muffler housing. The first lateral positioning mechanism and the second lateral positioning mechanism respectively align the two ends of the muffler housing. The detection block mechanism is used to limit and engage the muffler housing.

[0008] In a preferred embodiment, each set of gauge hole mechanisms includes a lower gauge hole frame mounted on the base plate and located at the bottom of the muffler housing, the lower gauge hole frame being connected to an upper gauge hole frame located at the top of the muffler housing via a first cylinder.

[0009] In a preferred embodiment, the first lateral positioning mechanism includes a cross-shaped locking disc and a driving mechanism for driving the cross-shaped locking disc to move laterally, the cross-shaped locking disc being disposed inside one end of the muffler housing.

[0010] In a preferred embodiment, the second lateral positioning mechanism includes an adjusting rod, a pressure plate, a positioning shell, and a fastening bolt. The pressure plate is located at one end of the adjusting rod near the muffler housing, and the adjusting rod is located inside the positioning shell. The top of the adjusting rod has two spaced fastening holes, and the bottom end of the fastening bolt penetrates the positioning shell and extends into one of the fastening holes.

[0011] In a preferred embodiment, the detection block mechanism includes a lower support plate mounted on the top of the base plate and located at the bottom of the muffler housing, and an upper clamping plate is provided on the top of the lower support plate.

[0012] In a preferred embodiment, the support mechanism includes multiple supports connected together by multiple support plates, and the upper gauge hole frame and the upper clamping plate are respectively installed on the top of the multiple supports by clamping latches.

[0013] In a preferred embodiment, upper pressing plates are provided between the two sets of gauge hole mechanisms and on the side of the two sets of gauge hole mechanisms that are far apart. Two lower pressing plates are provided at the bottom of the front and rear ends of the three upper pressing plates. The two lower pressing plates are installed on the top of multiple support plates. The upper pressing plates and lower pressing plates are used to position the side of the muffler housing.

[0014] In a preferred embodiment, a fixing frame is installed on the front side of the base plate, and an adjusting plate is movably connected to the front end of the fixing frame via a rotating shaft. Multiple spaced fans are installed inside the adjusting plate.

[0015] A servo motor is installed on one side of the front end of the fixed frame. The output shaft of the servo motor passes through the fixed frame and is fixed together with the rotating shaft on the adjustment plate.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] The holes on the muffler housing are engaged by the inspection hole mechanism, and the two ends of the muffler housing are aligned and leveled by the first and second lateral positioning structures. The two ends of the muffler housing are then pressed and fixed by the inspection block mechanism. Through this multi-directional positioning, the assembly accuracy of the muffler housing can be ensured, thereby improving the accuracy and stability of the subsequent welding of the muffler housing.

[0018] The servo motor drives the adjustment plate to rotate, thereby adjusting the angle of the adjustment plate and the blowing angle of the fan. The fan blowing intensity is then adjusted according to the welding requirements, so that the fan can disperse the smoke and reduce the operator's inhalation of harmful substances. At the same time, it can also accelerate the airflow and avoid the welding area from overheating and damaging the silencer housing, thereby improving welding efficiency and welding effect.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0035] Refer to the instruction manual appendix Figure 1-8 This utility model provides a muffler housing inspection tool, including an inspection tool provided on the top of the base plate 1 for fixing the muffler housing 2;

[0036] The inspection fixture includes a support mechanism 3 for supporting the muffler housing 2 in a mirror distribution, two sets of inspection hole mechanisms 4 for positioning the muffler housing 2, a first lateral positioning mechanism 5 and a second lateral positioning mechanism 6 for laterally positioning the muffler housing 2, and two sets of detection block mechanisms 7 respectively placed outside both ends of the muffler housing 2; the inspection hole mechanism 4 is used to position the holes opened on the muffler housing 2, the first lateral positioning mechanism 5 and the second lateral positioning mechanism 6 respectively align the two ends of the muffler housing 2, and the detection block mechanism 7 is used to limit and engage the muffler housing 2.

[0037] When the above-mentioned support mechanism 3, gauge hole mechanism 4, first lateral positioning mechanism 5, second lateral positioning mechanism 6 and detection block structure are used to fix the muffler housing 2, the support mechanism 3 includes multiple supports 32 connected together by multiple support plates 31. The upper gauge hole frame 43 and the upper clamping plate 72 are respectively installed on the top of the multiple supports 32 by pressing and locking buckles 33. In this way, the gauge hole mechanism 4 and the detection block mechanism 7 can be supported and fixed, thereby ensuring the stability of the gauge hole mechanism 4 and the detection block mechanism 7 when fixing the muffler housing 2.

[0038] For example Figure 2 , 3As shown in Figure 6, to improve the stability and accuracy of fixing the muffler housing 2, it is necessary to achieve multi-directional fixing and limiting, so that each set of gauge hole mechanisms 4 includes a lower gauge hole frame 41 installed on the base plate 1 and located at the bottom of the muffler housing 2. The lower gauge hole frame 41 is connected to the upper gauge hole frame 43 located at the top of the muffler housing 2 through the first cylinder 42. Thus, the lower gauge hole frame 41 can engage and fix the hole located at the bottom of the muffler housing 2, and the first cylinder 42 can drive the upper gauge hole... The bracket 43 is fixed to the hole on the top of the muffler housing 2, so that precise fixation can be achieved by the engagement of the hole. Since the detection block mechanism 7 includes a lower support plate 71 installed on the top of the base plate 1 and located at the bottom of the muffler housing 2, and an upper clamping plate 72 is provided on the top of the lower support plate 71, the lower support plate 71 and the upper clamping plate 72 can be limited by matching the shape of the muffler housing 2, thus ensuring the stability and firmness of the muffler housing 2.

[0039] Among them, such as Figure 4 As shown, in order to avoid the two ends of the muffler housing 2 being skewed or misaligned, it is necessary to limit the two ends of the muffler housing 2, so that the first lateral positioning mechanism 5 includes a cross-shaped locking disc 51 and a driving mechanism 52 for driving the cross-shaped locking disc 51 to move laterally. The cross-shaped locking disc 51 is located inside one end of the muffler housing 2. The operator operates the driving mechanism to move the cross-shaped locking disc 51 into the muffler housing 2, so that one end of the muffler housing 2 can be limited and fixed by the cross-shaped locking disc 51.

[0040] Furthermore, the second transverse positioning mechanism 6 includes an adjusting rod 61, a pressure plate 62, a positioning shell 63, and a fastening bolt 64. The pressure plate 62 is located at one end of the adjusting rod 61 near the muffler housing 2, and the adjusting rod 61 is located inside the positioning shell 63. The top of the adjusting rod 61 has two spaced fastening holes 65. The bottom end of the fastening bolt 64 penetrates the positioning shell 63 and extends into one of the fastening holes 65, allowing the operator to operate the adjusting rod 61 to bring the pressure plate 62 into contact with the other end of the muffler housing 2. This allows the pressure plate 62 to work with the cross-shaped locking disc 51 to limit the two ends of the muffler housing 2, making the two ends of the muffler flush and preventing misalignment or tilting. At the same time, the connection between the fastening bolt 64 and the fastening hole 65 can fix the displaced adjusting rod 61, thereby ensuring the stability of the pressure plate 62.

[0041] And such Figure 7As shown, the side of the muffler housing 2 can be limited, thereby enhancing the tightness of the fit of the muffler housing 2 and improving the accuracy of subsequent welding of the muffler housing 2. Thus, upper pressing plates 12 are provided between the two sets of inspection hole mechanisms 4 and on the side away from the two sets of inspection hole mechanisms 4. Two lower pressing plates 13 are provided at the bottom of the front and rear ends of the three upper pressing plates 12. The two lower pressing plates 13 are installed on the top of multiple support plates 31. The upper pressing plates 12 and lower pressing plates 13 are used to position the side of the muffler housing 2. The upper pressing plates 12 are installed on the top of the support plates 31 by the second cylinder 14. The lower pressing plates 13 support the bottom side of the muffler housing 2. Then, the upper pressing plates 12 are moved down by the second cylinder 14 to support the top side of the muffler housing 2. In this way, the muffler housing 2 can be tightly fitted.

[0042] Meanwhile, in order to improve welding efficiency and welding effect, such as Figure 1 and 8 As shown, a fixed frame 8 is installed on the front side of the base plate 1. An adjusting plate 9 is movably connected to the front end of the fixed frame 8 via a rotating shaft. Multiple spaced fans 10 are installed inside the adjusting plate 9. A servo motor 11 is installed on one side of the front end of the fixed frame 8. The output shaft of the servo motor 11 passes through the fixed frame 8 and is fixed together with the rotating shaft on the adjusting plate 9. The servo motor 11 drives the adjusting plate 9 to rotate, thereby adjusting the angle of the adjusting plate 9 and thus adjusting the blowing angle of the fans 10. The blowing intensity of the fans 10 is then adjusted according to the welding requirements. This allows the fans 10 to disperse smoke and reduce the operator's inhalation of harmful substances. At the same time, it can also accelerate airflow and avoid overheating of the welding area, which could damage the silencer housing 2. This improves welding efficiency and welding effect.

[0043] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
