Contour Measuring Instrument for Shaft Parts and Its Application

Abstract

A shaft part contour measuring instrument comprises a base, a lathe bed, a measuring mechanism, a tail bracket, a head bracket, clamping air-floating guide rails and a counterweight mechanism. The measuring mechanism comprises an X-axis measuring component, a Z-axis drive dragging plate and a Z-axis air-floating dragging plate, and the Z-axis drive dragging plate is driven to move along measuring air-floating guide rails by a drive screw rod of a measuring drive motor; the tail bracket is driven to move along the clamping air-floating guide rails by the drive screw rod of a clamping drive motor, and the head bracket directly faces to the tail bracket and is provided with a clamping slewing mechanism used for clamping a shaft part to be measured by matching with the tail bracket so that the part can be rotated around the axis of the part; the counterweight mechanism is located on the top of the shaft part contour measuring instrument, and used for balancing the measuring mechanism and the tail bracket; and the invention also provides the application of the shaft part contour measuring instrument. The shaft part contour measuring instrument provided by the invention is capable of clamping and unloading workpieces automatically, and the high-accuracy and high-efficiency positioning of the top of the tail bracket is achieved; and the installation and positioning accuracy of the workpiece is improved.

Description

technical field [0001] The invention relates to a measuring instrument, in particular to a profile measuring instrument for shaft parts and its application. Background technique [0002] Shaft parts such as crankshafts and camshafts are key parts of power drive components in the equipment manufacturing industry, and their processing quality is directly related to the overall performance of power drive components. Compared with developed countries, there is a big gap in the domestic research level on the processing technology and stability of crankshafts, camshafts and other shaft parts. The measurement technology is one of the key factors restricting the quality improvement of crankshafts, camshafts and other shaft parts. To a certain extent, the high-precision contour accuracy of crankshafts, camshafts and other shaft parts obtained by using special measuring equipment Guide the processing technology. [0003] The error detection technology and efficient special instrumen...

Problems solved by technology

[0004] At present, the commonly used measuring instruments such as crankshaft and camshaft on the market, the lifting of the top of the tailstock and the auxiliary clamping mechanism of the headstock are all manual, which increases the time for workpiece installation and adjustment, thereby reducing the measurement efficiency, and the price of the measurement and the later stage high maintenance cost
