Abstract

The invention provides a machining workpiece notch flatness detecting device including a working table. A stand rack, a stand rod and a clamping mechanism are mounted on the working table. The machining workpiece notch flatness detecting device is characterized in that the stand rod is equipped with a control system; two sides of the clamping mechanism are both provided with blocking spring rollers and pressing spring rollers. A bottom plate pushed through a spring post is mounted below the clamping mechanism. An ejection cylinder is also mounted on a side edge of the bottom plate. The top ofthe clamping mechanism is equipped with a pin roll. The pin roll is equipped with an upper clamp controlled to open and to close through a handle. The invention has beneficial effects that detection of a machining workpiece notch can be performed automatically by utilizing a reasonable structural design; the whole detection process is automatic and high in speed and detection efficiency; and the device and the method are suitable for promotion and use.

Description

technical field [0001] The invention relates to a device for detecting the flatness of a notch of a machined part and a detection method thereof, belonging to the technical field of mechanical engineering. Background technique [0002] Measurement of flatness errors in length metrology. The plane is composed of straight lines, so the ruler method, optical collimation method, optical self-collimation method, gravity method, etc. in straightness measurement are also suitable for measuring flatness error. When measuring flatness, first measure the straightness of several sections, and then define the value of each measuring point according to the flatness tolerance zone (see shape and position tolerance). The flatness error can be obtained by data processing by graphic method or calculation method . [0003] For example, a publication number of CN107843217A discloses a heat sink flatness tester, the flatness tester includes a flatness tester, the flatness tester includes a sh...
