Description

Technical Field

[0001] This utility model relates to the field of muffler assembly technology, specifically to a tooling for muffler sub-assemblies, used for locking and fixing the muffler core. Background Technology

[0002] To achieve noise reduction, car mufflers typically contain one or more different core components. (See also...) Figure 4 The image shows an intake core and an exhaust core. The intake core consists of a perforated intake pipe 17 and a baffle 18, while the exhaust core consists of a non-perforated exhaust pipe 16 and a baffle 19.

[0003] Although the two types of cores use slightly different parts, both types of cores use a locking mechanism to secure the tubes and partitions together. Currently, the production of these two types of cores requires two sets of corresponding locking fixtures and two locking machines. Alternatively, using one locking machine would require frequent tooling changes, resulting in low production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a tooling for a muffler sub-assembly with a reasonable structure and reliable use. It is applicable to both the intake and exhaust cores of the muffler. Both cores can share one tooling, requiring only one locking device. This eliminates the need for frequent tooling changes and significantly improves production efficiency.

[0005] The technical solution of this utility model is:

[0006] A tooling for a muffler sub-assembly includes a base plate. The key technical features are: two parallel X-axis linear guides are provided on the upper surface of the base plate; an X-axis movable support plate is provided above the X-axis linear guides; two parallel Y-axis linear guides are provided on the upper surface of the X-axis movable support plate; a Y-axis movable support plate is provided above the Y-axis linear guides; an intake core fixing assembly and an exhaust core fixing assembly are fixed on the upper surface of the Y-axis movable support plate, spaced apart along the X-axis; the intake core fixing assembly and the exhaust core fixing assembly each include a front support seat, a rear support seat, and a positioning bracket located between the front and rear support seats, spaced apart along the Y-axis; positioning grooves corresponding to the pipe column are provided on the upper surfaces of the front and rear support seats; a limiting plate higher than the bottom surface of the positioning groove is fixed to the rear side of the rear support seat; the positioning bracket has positioning slots corresponding to the two edges of the partition plate; and an anti-misalignment component is further fixed to the rear side of the rear support seat of the exhaust core fixing assembly.

[0007] The aforementioned tooling for the muffler sub-assembly has different distinguishing marks on the top surface of the front support of the intake core fixing assembly and the exhaust core fixing assembly.

[0008] The tooling for the above-mentioned muffler sub-assembly includes a hollow sleeve and an anti-misalignment pin provided in the hollow sleeve, with the inner end of the anti-misalignment pin pointing towards the positioning bracket.

[0009] The aforementioned tooling for the muffler sub-assembly has a first drive handle on the edge of the X-direction movable support plate and a second drive handle on the edge of the Y-direction movable support plate.

[0010] The aforementioned tooling for the muffler sub-assembly has a connecting plate at the front end of the base plate for connecting with the locking device. A side reinforcing plate is provided between the connecting plate and the left and right edges of the base plate. A clearance opening corresponding to the core locking system is provided in the middle of the upper end of the connecting plate.

[0011] The aforementioned tooling for the muffler sub-assembly has weight reduction hole groups on the base plate and the X-direction movable support plate.

[0012] The beneficial effects of this utility model are:

[0013] The intake core fixing assembly and exhaust core fixing assembly support the intake core and exhaust core respectively. The Y-axis movable support plate can move the intake core or exhaust core into or out of the locking position, while the X-axis movable support plate movement enables quick switching between the intake core and exhaust core. This fixture only requires one locking device, eliminating the need for frequent fixture changes. It is suitable for locking production of both types of cores, significantly improving production efficiency. Attached Figure Description
