Testing fixture of quickly measuring the location degree of bend axle flange end holes

Abstract

The invention discloses a testing fixture of quickly measuring the location degree of bend axle flange end holes. The testing fixture of quickly measuring the location degree of bend axle flange end holes includes a location disk, a thin nut, a handle, a pinhole testing pin and screw hole testing pins, wherein one end surface of the location disk is provided with a ring-shaped location groove; a slantingly-downward escape is arranged along one circle of the outer side edge of the ring-shaped location groove on the location disk; mounting holes 1 are formed in the ring-shaped location groove along one circumferential circle of the ring-shaped location groove; a mounting hole 2 is formed between two of the mounting holes 1; each mounting hole 1 is in interference fit with the screw hole testing pin; the mounting hole 2 is in interference fit with the pinhole testing pin; a screw hole is formed in the middle location of the other end surface of the location disk; the screw hole is provided with the handle; a ring-shaped transition groove and a location hole are successively formed on the location disk from the ring-shaped location groove to the screw hole; and the upper port end of the location hole is provided with a chamfer. Therefore, the testing fixture of quickly measuring the location degree of bend axle flange end holes has the advantages of being convenient for arrangement of manpower resource, greatly reducing the labor intensity of workers, greatly improving the detection efficiency and being suitable for mass detection.

Description

technical field [0001] The invention relates to a checking tool, in particular to a checking tool for quickly measuring the position degree of a crankshaft flange end hole system, and belongs to the technical field of crankshaft checking tools. Background technique [0002] The crankshaft is a standard accessory in the auto parts industry. Not only is the processing technology cumbersome, there are many processing procedures, but also the size of the processed crankshaft needs to be strictly inspected. At present, in the process of detecting the position of each hole at the flange end of the crankshaft, the crankshaft is first placed on the V-shaped frame and adjusted to a horizontal position, and the threaded holes at the flange end are tightened with hexagon head bolts, and the holes are fixed with a plug gauge. Insert it into the positioning pin hole, then pull the connecting rod to the horizontal position, measure the X-direction and Y-direction coordinates of the positi...

Problems solved by technology

Although the detection accuracy is high in this way, on the one hand, it not only needs the working platform and other tools to be used together, but due to the limitation of the site, it cannot be tested anytime and anywhere, and it requires high practical operation and experience of the inspectors, making it difficult to allocate human resources; on the other hand On the one hand, this kind of detection has the disadvantages of cumbersome operation and troublesome calculation, and sometimes the plug gauge cannot be plugged to the bottom due to the force generated by the air squeeze inside the threaded hole, which not only greatly increases the labor intensity of the staff, but also greatly reduces the detection efficiency , not suitable for mass detection
