Embodiment Construction

[0018] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0019] like figure 1 and figure 2 As shown: in order to directly measure the camshaft lift and save processing time, the present invention includes a base 1 on which a guide shaft 3 is arranged, and one end of the guide shaft 3 is provided for connecting with the cam profile of the camshaft 18 The contact measuring wheel 7, the other end of the guide shaft 3 is provided with a dial indicator 17 for measuring the lift, and the measuring head of the dial indicator 17 is in contact with the end of the guide shaft 3.

[0020] Specifically, the measuring wheel 7 is at one end of the guide shaft 3, and the measuring wheel 7 can be in contact with the cam profile of the camshaft 18. When the camshaft 18 rotates, the cam profile of the camshaft 18 has a certain amount of lift, so The lift amount of the cam profile of the camshaft 18 acts on the measuring wheel 7, an...

Abstract

The invention relates to a measuring device, in particular to an online measuring device for a camshaft lift angle, and belongs to the technical field of camshaft lift angle measurement tooling. According to the technical solution provided by the present invention, the online measuring device for the included camshaft lift angle includes a base, a guide shaft is arranged on the base, and one end of the guide shaft is used for measuring the contact with the cam surface of the camshaft The other end of the guide shaft is provided with a dial gauge for measuring the lift, and the measuring head of the dial gauge is in contact with the end of the guide shaft. The invention has a compact structure, can directly measure the lift of the camshaft, saves processing time, can directly perform secondary adjustments according to the measurement data, improves production efficiency and processing accuracy, and is safe and reliable.

Description

technical field [0001] The invention relates to a measuring device, in particular to an online measuring device for a camshaft lift angle, and belongs to the technical field of camshaft lift angle measurement tooling. Background technique [0002] When machining the camshaft, it is necessary to mill the profile of the camshaft. After the camshaft profile is milled, the camshaft with the milled cam profile needs to be removed from the machine tool, and the measuring room uses special instruments for measurement. After the camshaft is removed from the machine tool, the processing positioning reference is lost, and the measurement data cannot be directly adjusted by the secondary clamping method, which also causes a waste of time. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide an online measuring device for the camshaft lift angle, which has a compact structure, can directly measure the ca...
