Problems solved by technology

[0003] The cam is a mechanism widely used in the mechanical field. The cam mechanism is not only simple in structure, reliable in positioning, but also capable of stable transmission. However, the processing of the cam arc surface requires high-precision equipment testing; currently, there is no low-cost and high-precision testing equipment in China. , The equipment is simple to operate and can meet the measurement of the lift curve and machining accuracy of the VE pump end face cam for diesel engines

Abstract

The invention provides an end cam lift detection device. The end cam lift detection device is characterized in that the end cam lift detection device comprises a working bench, a detection assembly, a clamping assembly, a power rotation assembly, and an installation base installed on the workbench; the end cam lift detection device is capable of precisely detecting the lift of an end cam and has important significance for improving a lift curve of the end cam and further improving the oil supplying rule of a VE dispensing pump; the end cam lift detection device serving as a detection device which is low in cost, high in detection precision and simple in operation fills the gap in the field in China, effectively determines and controls the machining quality effect of the end cam and also substantially saves capital investment and production cost for an enterprise; in addition, the detection system can be used for online detection and product inspection of a production field, so that the recording of product quality, and the storage and management of quality data are convenient.

Description

technical field [0001] The invention relates to a cam lift detection device, which is suitable for measuring the cam lift curve of the end surface of a VE pump used for a diesel engine and its machining accuracy. Background technique [0002] With the continuous improvement of science and technology and living standards in our country, people are demanding product quality and at the same time pursuing product diversity and updating speed, which requires manufacturers to speed up product development and product appearance innovation. In the middle of the 20th century, in order to further shorten the gap with foreign advanced technologies, our country formulated a strategy of introduction, digestion, absorption, and re-innovation. That is reverse engineering. [0003] The cam is a mechanism widely used in the mechanical field. The cam mechanism is not only simple in structure, reliable in positioning, but also capable of stable transmission, but the processing of the cam arc ...
