Embodiment 1

[0026] Such as figure 1 , a kind of muffler cylinder opening calibration tooling, comprising a base plate 6, a support seat 5 and two muffler cylinder opening calibration platforms, one end of the base plate 6 is provided with a dovetail groove 8 narrow at the top and wide at the bottom along the base plate 6, and the dovetail A matching slider 9 is also provided in the groove 8, one of the muffler opening calibration platform is fixedly connected to the slider 9, and the other is fixedly connected to the end of the other end of the bottom plate 6, and the support seat 5 is fixedly connected on the bottom plate 6 between the opening check benches of the two muffler cylinders, the said muffler tank opening check bench includes a threaded rod 1, a threaded seat 2, a support block 3 and a muffler cylinder opening die 4, and supports The block 3 is provided with a hole through the two sides, the threaded seat 2 passes through the hole and is fixedly connected with the support bloc...

Embodiment 2

[0029] This embodiment is further improved on the basis of embodiment 1, as figure 1 , also includes tightening bolts 7 and support block lug 31, the side of the support block lug 31 is fixedly connected with the side of the support block 3, and the support block lug 31 is provided with an internal threaded hole perpendicular to the plane of the bottom plate, so The jacking bolts 7 are threadedly fitted with the support block lugs 31.

[0030] There are four supporting lugs 31 and four tightening bolts 7 , which are respectively distributed on the two sides of the supporting block 3 on both sides of the dovetail groove 8 .

[0031] There are at least two support bases 5, and they are all connected with the bottom plate 6 by bolts.

[0032] It also includes two handwheels 10, and the two handwheels 10 are respectively fixedly connected to the other ends of the respective threaded rods 1 on the opening test benches of the two mufflers.

[0033] The upper surface of the support...

Abstract

The invention discloses a muffling tube opening check tooling, which comprises a base plate (6), supports (5) and two muffling tube opening check platforms, wherein one end of the base plate (6) is provided with a downwardly widened dovetail groove (8) along the base plate (6), a slider (9) matched with the dovetail groove (8) is also arranged in the dovetail groove (8), and each muffling tube opening check platform comprises a threaded rod (1), a threaded holder (2), a supporting block (3) and a muffling tube opening mold (4). The muffling tube opening check tooling has a simple structure, is easy to manufacture, and provides produced muffling tubes with a similar mounting position, a muffling tube to be checked is arranged on the supports, the muffling tube opening mold is adjusted to be compared with the opening of the muffling tube, and therefore whether the positional relation of the opening of the muffling tube can meet requirement or not can be clearly reflected; the distance between the two muffling tube opening check platforms can be adjusted, so that the muffling tube opening check tooling can check the positional relation of the opening of the muffling tube within a wide length range.

Description

technical field [0001] The invention relates to the field of inspection equipment for mufflers, in particular to a tool for checking the opening of a muffler. Background technique [0002] The muffler is a device that allows airflow to pass through and attenuates noise. It is one of the important parts of the vehicle. When the high-temperature exhaust gas of the engine enters the muffler through the exhaust pipe at high speed, the cross-sectional area of ​​the muffler gradually increases. The airflow is expanded, the flow rate is reduced, and the powerful pulsation noise is attenuated. The performance of the muffler not only affects the size of the vehicle noise, but also has a great influence on the power, fuel consumption, torque and other performance of the engine. Existing mufflers for vehicles can be divided into two types: mufflers and mufflers according to their shape and structure, and mufflers are generally resistant or impedance composite mufflers. Compared with b...
