Description

Technical Field

[0001] This utility model relates to a test bench exhaust pipe connector, belonging to the technical field of engine test bench exhaust systems. Background Technology

[0002] In the engine manufacturing process, the test bench process exhaust pipe is a key component of the hot test bench exhaust system. Its core function is to guide the high-temperature, high-pressure exhaust gas generated by engine combustion from the cylinder to the outside of the test bench or a specific emission area. Taking the JL484ZQ1 engine as an example, certain process steps in its production (such as exhaust gas detection and simulated operating condition exhaust) require connection to the process exhaust pipe through the turbine regulator exhaust port to achieve directional exhaust of exhaust gas and precise control of process parameters.

[0003] However, traditional exhaust pipe fittings have the following technical drawbacks:

[0004] 1. Poor compatibility; the process of connecting with the exhaust port of the turbine regulator and the process hose is cumbersome and the disassembly and assembly operations are time-consuming, which directly leads to a reduction in production efficiency.

[0005] 2. The sealing performance of the connection parts is unstable, which can easily lead to exhaust gas leakage in actual use. This will not only pollute the working environment, but also affect the accuracy of data in process links such as exhaust gas detection due to the escape of exhaust gas. Summary of the Invention

[0006] To address the problems existing in the background art, this utility model provides a test bench process exhaust pipe connector.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a test bench process exhaust pipe connector, comprising a connector pipe body; the connector pipe body is an L-shaped pipe, the air inlet end of the connector pipe body is a conformal interface end, the inner diameter of the conformal interface end is matched with the outer diameter of the turbine regulator exhaust port, and a sealing ring groove is provided on the outer side of the conformal interface end; a sealing ring is installed in the sealing ring groove; the air outlet end of the connector pipe body is a hose connection end, and a protrusion is provided on the outer side of the hose connection end, the protrusion being press-fitted with the inner wall of the process hose.

[0008] Furthermore, the connector tube body is made of a high-temperature and corrosion-resistant metal material.

[0009] Furthermore, the sealing ring in the sealing ring groove is a high-temperature resistant fluororubber sealing ring.

[0010] Furthermore, a clamping platform is installed at the corner of the connector tube body, and the clamping platform is used in conjunction with the clamping mechanism.

[0011] Furthermore, the clamping mechanism includes a positioning seat, a pusher, a connecting rod, a hinged rod, and a push rod; the positioning seat is fixedly connected to the test bench, and the positioning seat is hinged to the inner end of the connecting rod and the inner end of the push rod. The middle part of the connecting rod is hinged to one end of the hinged rod, the other end of the hinged rod is hinged to the middle part of the push rod, and the outer end of the connecting rod is detachably fixedly connected to the pusher.

[0012] Furthermore, a heat-resistant handle is fixed to the outer wall of the connector tube body.

[0013] Furthermore, the hose connection end is also tightened to the process hose by a hose clamp.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model precisely adapts to the exhaust port size of the turbocharger regulator, and, in conjunction with a high-temperature resistant fluororubber sealing ring, effectively ensures the sealing performance of the connection, preventing exhaust gas leakage from polluting the working environment and affecting the accuracy of process testing data. Through interference fit, optional hose clamp reinforcement, and a quick clamping mechanism, it achieves rapid disassembly and assembly of the exhaust pipe joint and process hose, as well as stable overall connection, significantly shortening production time and improving the efficiency of engine production processes. Using high-temperature and corrosion-resistant metal materials, the exhaust pipe direction and shape are rationally planned, and a heat-resistant handle is provided to meet the needs of different operating conditions in engine production and ensure stable exhaust gas transmission.
