The invention relates to a machining and fixing device for shaft parts and a debugging method of the machining and fixing device to solve the technical problems that when the shaft parts are horizontally positioned at present, operation is tedious, consumed time is long, and efficiency is low. The device comprises a base, an adjustable supporting assembly and a fixed supporting assembly. The adjustable supporting assembly comprises an adjustable V-shaped block, a first adjustable pressing unit and an adjusting unit. The adjusting unit comprises a U-shaped frame, a cross beam arranged in the U-shaped frame, an adjusting screw rod and a locking screw, and the adjusting screw rod penetrates through the cross beam from the lower end and then abuts against the lower end of the adjustable V-shaped block; the locking screw abuts against the side face of the adjustable V-shaped block. The method comprises the steps that 1, the machining fixing device is installed, and the straightness is adjusted to be smaller than or equal to 0.02 through a cylindrical standard part; 2, two positioning circles are selected, and the number of turns of rotation of the adjusting screw rod is calculated according to the radiuses of the two positioning circles; 3, the straightness of the upper end of the adjusted part to be machined is measured to be smaller than or equal to 0.02; and 4, the to-be-machined part is measured and taken down.
Description
technical field [0001] The invention relates to a processing fixing device and a debugging method thereof, in particular to a processing fixing device for shaft parts and a debugging method thereof. Background technique [0002] As we all know, the combination fixture is simple to manufacture, low cost, widely used, and has a variety of combination forms. Therefore, the combination fixture has become the earliest and most used clamping element, and is widely used in the clamping and positioning structure of mechanical engineering. It is widely used in various fields of the national economy. plays an important role in. However, the assembly of the combined fixture is very cumbersome. When positioning the shaft parts, in order to ensure that the axis of the parts is in a horizontal state, it is necessary to calculate and select a suitable pad for height adjustment. Generally, 3-4 spacers are required for stacking. Therefore, how to easily level the axis of the shaft parts is...
