Description

TECHNICAL FIELD

[0001] The utility model belongs to large -scale shaft processing technical field, concretely relates to a simple and easy alignment scribing device of shaft blank. BACKGROUND

[0002] The existing multi-step shaft workpiece polishing processing mode mainly adopts the method that the workpiece is placed on the machine tool workbench, is aligned, is pressed tightly, then the outer cylindrical surface of the cutter (generally milling cutter or machine tool spindle) is contacted with the reference surface A, and processing is carried out along the spindle axis direction. In the processing process, since the workpiece is multi-step shaft workpiece, there is a certain eccentric distance between each step, multiple alignment adjustment is needed, and there is also the problem that the finally processed workpiece does not meet the design requirements due to the large eccentric distance, causing the workpiece to be scrapped, and increasing the production cost of enterprises. SUMMARY

[0003] The utility model discloses a simple and easy alignment scribing device of shaft blank, simple structure, time -saving and labor -saving operation, reduce the production cost of enterprise.

[0004] The technical scheme of the utility model discloses the following beneficial effects:

[0005] A simple and easy alignment scribing device of shaft blank, including horizontal reference platform, four measuring rods and centering rope, the horizontal reference platform is used to place the workpiece to be aligned, each measuring rod is movably provided with a hook through a bolt, the hook moves along the axial direction of the measuring rod, the four measuring rods are evenly distributed around the workpiece to be aligned, the centering rope is hung on the hook, and is used to form a circle along the four measuring rods and is parallel to the axis of the workpiece to be aligned.

[0006] Further, the centering rope is replaced by a steel wire.

[0007] Further, the lower end of the measuring rod is provided with a base.

[0008] Further, the measuring rod is provided with a scale along the axial direction.

[0009] Further, the hook is provided with a sleeve that is sleeved on the measuring rod, the sleeve is provided with a threaded hole, and the bolt is installed in the threaded hole.

[0010] Further, the bolt is a butterfly bolt.

[0011] The above technical scheme has the following beneficial effects:

[0012] The simple structure of the utility model, for many steps shaft, do not need to place the workpiece to be aligned on the grinding machine to grind and align each step one by one, can measure in advance whether the eccentric distance of the workpiece to be aligned meets the product design requirement, avoid the processed product not meeting the quality requirement, thereby avoid wasting manpower and material resources, especially for large multi-step shaft, due to the weight and volume of the workpiece, early alignment can effectively avoid material waste, reduce the production cost of enterprises.

[0013] Further description is made below in combination with the drawings and specific embodiments. BRIEF DESCRIPTION OF DRAWINGS

[0014] Figure 1 It is a structure schematic view of specific embodiment 1;

[0015] Figure 2 It is a structure schematic view of specific embodiment 1 in use state.

[0016] In the drawings, 1 is a horizontal reference table, 2 is a measuring rod, 3 is a hook, 4 is a bolt, 5 is a centering rope. SPECIFIC EMBODIMENT Specific embodiment 1:

[0018] Referring to Figure 1 And Figure 2 As shown, a simple alignment scribing device for shaft blanks, comprising a horizontal reference table 1, four measuring rods 2, a marking pen and a centering rope 5, the horizontal reference table 1 is used for placing the workpiece to be aligned, the workpiece to be aligned 7 is a multi-step shaft, which ensures that the workpiece to be aligned is in the same horizontal plane, improving the measurement accuracy. The horizontal reference table 1 can also be provided with an area on the ground at the same horizontal plane. Each of the measuring rods 2 is movably provided with a hook 3 through a bolt, the hook 3 moves along the axial direction of the measuring rod, the measuring rod 2 is a metal rod, and the lower end of the measuring rod 2 is provided with a base 6. In this specific embodiment, the base 6 is a rectangular metal base. A scale is provided on the measuring rod 2 in the axial direction, which facilitates the adjustment of the up-down position of the hook 3. The hook 3 is provided with a sleeve that is sleeved on the measuring rod, a threaded hole is formed in the sleeve, and a bolt 4 is installed in the threaded hole. The bolt 4 is a butterfly bolt, which can adjust the position of the hook in time according to the axial position of the workpiece to be aligned.

[0019] The four measuring rods 2 are evenly distributed around the workpiece to be aligned, and the centering rope 5 is hung on the hook 3 and used to form a circle along the four measuring rods 2, which is parallel to the axis of the workpiece to be aligned.

[0020] Possibly, the centering rope 5 is replaced by a steel wire.

[0021] Working principle of the utility model:

[0022] The workpiece to be aligned is placed on the horizontal reference table 1, four measuring rods 2 are arranged at the four corners of the workpiece to be aligned, the centering rope 5 is hung on the hooks 3 to form a loop along the four measuring rods, each step axis of the workpiece to be aligned is measured, the center line of each step is found out and marked with a marker pen, and finally whether the eccentric distance is greater than the design requirement is judged according to the center line of each step, so as to obtain whether the workpiece to be aligned can process the product meeting the design requirement, and the mark is also convenient for alignment in subsequent machine tool processing.
