Problems solved by technology

Since the workpiece is a stepped shaft, the existing alignment tool is equipped with two "V"-shaped irons. During the alignment and fixing process, two "V"-shaped irons are used to pad the two ends of the shaft, and the spacer and copper sheet are used to adjust. The level of the workpiece is adjusted by moving the position of the V-shaped iron to adjust the straightness of the workpiece. Due to the large number of transmission shafts, the above method of tooling alignment takes too long and is not suitable for mass production. Therefore, the processing efficiency in the production process Poor and prone to quality issues

Embodiment Construction

[0009] Embodiments of the present invention are further described below with reference to the accompanying drawings.

[0010] The new shaft parts alignment tool of the present invention as shown in the figure (see appendix) figure 1 , 2 ), there are two "V" type irons 2, which are characterized in that: the two "V" type irons are welded on the flat plate 1, the "V" grooves of the two "V" type irons 2 are longitudinally on the same axis, and the two "V" type irons are on the same axis. The inclined surfaces of the "V" groove of the V" type iron 2 are respectively machined with arc surfaces that match the corresponding outer circles of the shaft parts. Empty sipe 3 of poor size. In this way, when processing to find straight line timing, use such as figure 2 Shown, a new type of shaft parts alignment tool. Before processing, place the first step shaft on the "V" type iron, find the straight line by the side of the bottom plate of the "V" type iron, and find the level by the ...

Abstract

A novel shaft part alignment tool is provided with two V-shaped irons (2) and is characterized in that the two V-shaped irons are welded on a flat plate (1), V-shaped grooves of the two V-shaped irons (2) are longitudinally located on the same axis, arc surfaces matched with corresponding outer circles of shaft parts are machined on inclined surfaces of the V-shaped grooves of the two V-shaped irons (2) respectively, and clearance grooves (3) lower than the maximum normal work difference size of the outer circles of the shaft parts are formed in the bottoms of the V-shaped grooves of the V-shaped irons. The shaft can be aligned by placing the shaft on the tool, or a copper sheet only needs to be padded between the corresponding outer circle and the arc surface of the shaft part. And the processing efficiency and the product quality are improved in production.

Description

Technical field: [0001] The invention relates to a tool for processing key grooves of 600-ton crane shaft parts. Background technique: [0002] For the drive shaft of the wheel on the crane, due to the high precision requirements of the shaft, the position of the keyway processing is strictly required, so the requirements for the alignment accuracy of the workpiece before processing are also correspondingly improved. Since the workpiece is a stepped shaft, the existing alignment tool is equipped with two "V"-shaped irons. In the process of alignment and fixation, two "V"-shaped iron pads should be used at both ends of the shaft and adjusted with gaskets and copper sheets. The level of the workpiece is positive, and the straight line of the workpiece is adjusted by moving the position of the V-shaped iron. Due to the large number of transmission shafts, according to the above-mentioned tool alignment method, the time is too long, and it is not suitable for mass production. Th...
