Detailed Description
The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1 to 7, the present embodiment provides a processing tool for milling a kidney-shaped hole and drilling a through hole in a coupling, including a spline mandrel 1 and a positioning stopper 2, where the positioning stopper 2 is sleeved on the spline mandrel 1 and provided with a positioning surface 22 for positioning the coupling 3, the coupling 3 is sleeved on the spline mandrel 1, is fixedly connected to the spline mandrel 1 through a spline, and is attached to the positioning surface 22 on the positioning stopper 2 for positioning, and the processing tool is mounted on a processing device for processing the coupling 3 through the spline mandrel 1.
The spline mandrel 1 is of a stepped shaft structure, the small-diameter section 11 of the spline mandrel is a cylindrical shaft, the large-diameter section 12 of the spline mandrel is provided with an external spline which can be matched with the internal spline of the coupling 3, and the stepped surface 13 of the spline mandrel 1 is perpendicular to the axis of the spline mandrel 1.
The locating stop block 2 is cylindrical, two ends (a left end face 23 and a right end face 22) of the locating stop block are of a plane structure, a through hole 21 is formed in the center of the locating stop block 2 and is sleeved on the large-diameter section 12 of the spline mandrel through the through hole 21 in a coaxial mode, and the diameter of the through hole 21 of the locating stop block is equal to or larger than the outer diameter of the outer spline section 12 of the spline mandrel 1, so that installation is facilitated. One end surface of the positioning stopper 2 (a left end surface 23 of the positioning stopper 2 shown in fig. 1 and 5) is overlapped with the stepped surface 13 of the spline spindle 1, and the other end surface (a right end surface 22 of the positioning stopper 2 shown in fig. 1 and 5) is a positioning surface and is attached to the end surface of the coupling 3.
The working principle of the structure is as follows:
when a kidney-shaped hole is milled and a through hole is drilled on the coupling 3, firstly, a small-diameter section 11 of the spline mandrel 1 is clamped through a three-jaw chuck (not shown in the figure), the end face of the three-jaw chuck is attached to a step face 13 of the spline mandrel 1 for aligning the machining tool, then a positioning block 2 is sleeved on an external spline of the spline mandrel 1, a left end face 23 of the positioning block 2 is attached to the end face of the three-jaw chuck, the size of a central through hole 21 of the positioning block 2 is equal to or larger than that of the external spline of the spline mandrel 1 for convenient installation, then a coupling 3 of a product is sleeved on the external spline of the spline mandrel 1, a left end face of the coupling 3 is attached to and positioned with a right end face 22 of the positioning block 2 and is connected and fixed with the external spline of the spline mandrel 1 through matching of an internal spline of the coupling 3, and the right end of the coupling 3, the product shaft coupling 3 is convenient to install and align, and the product shaft coupling 3 can be compressed and fixed, so that the product shaft coupling 3 is processed. After the product coupling 3 is machined, the tip is removed, the coupling 3 is taken down, then the next group of couplings 3 are sleeved on the spline mandrel 1 and are attached and positioned with the positioning surface of the positioning stop block 2, and the next group of products to be machined are clamped by the same method.
By adopting the processing tool, the scribing process, the milling process and the drilling process can be completed through the numerical control milling process by one-time clamping, the position is accurate, repeated disassembly and assembly and alignment of a product piece, scribing and replacement of processing equipment are avoided, and the problems of difficult clamping and positioning, process redundancy, incapability of ensuring precision and low efficiency in the processing process of milling the kidney-shaped hole of the coupling product and drilling the through hole are solved. When the processing tool is not used, the shaft coupling can be clamped and aligned only by the four-jaw chuck because the clampable part of the shaft coupling is a special-shaped blank surface which is not processed; after the processing tool is adopted, the cylindrical surface of the spline mandrel can be directly clamped by the three-jaw chuck, the three-jaw chuck has a self-centering function, the coupling can be clamped and aligned more conveniently, the four-jaw chuck can be prevented from directly clamping the coupling to perform hole processing, the problem of deformation of a processing hole position is caused due to the fact that the coupling clamped on the outer blank surface shakes, and the size precision and the shape precision of a workpiece are improved. Simultaneously, the shaft coupling suit is on the spline mandrel, and the spline mandrel can support the shaft coupling for the shaft coupling atress is even in carrying out the spot facing work in-process, improves the machining precision.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
