Problems solved by technology

[0003] However, most of the existing negative pressure test devices only have a nozzle with a fixed inner diameter, so a vacuum with a constant flow rate has to be used to test parts. Such negative pressure devices often cannot reliably and effectively simulate various working conditions of the engine. The product quality cannot be guaranteed, let alone meet the quality requirements of modern products. There are certain

Abstract

The invention discloses a throttle body negative pressure testing device, which comprises an aluminum alloy rack (1), a stepped motor controller (2), a negative pressure display (3), a negative pressure switching chamber (4), a clamping mechanism (5) and a positioning table (6), wherein the clamping mechanism (5) and the positioning table (6) are fixed on a mounting plate of the aluminum alloy rack (1); the negative pressure switching chamber (4) is arranged below the mounting plate, can be switched, and consists of an upper cover, a lower cover, measuring orifices, a threaded cylinder, end caps, an air inlet joint and a connecting bolt; at least two groups of measuring orifices of different type numbers are formed on the upper cover; and matched negative pressure nozzles and end caps are arranged on each measuring orifice. The throttle body negative pressure testing device can stably provide vacuum flows of various specifications to meet various negative pressure testing requirements of a throttle body and widen a testing range, is favorable for improving the detection quality of the throttle body product, and has the characteristics of simple structure, convenience of operation, high universality and the like.

Description

technical field [0001] The invention relates to a test device, in particular to a throttle body negative pressure test device. Background technique [0002] At present, negative pressure testing is involved in many industries, especially in the detection of engine-related parts in the automotive industry. After assembly, the actual working conditions of the engine will be simulated, and a certain flow of vacuum will be used to test the qualified parts. or not. [0003] However, most of the existing negative pressure test devices only have a nozzle with a fixed inner diameter, so a vacuum with a constant flow rate has to be used to test parts. Such negative pressure devices often cannot reliably and effectively simulate various working conditions of the engine. The product quality cannot be guaranteed, let alone meet the quality requirements of modern products. There are certain limitations in the related test extension of the throttle body, which is not conducive to the sta...
