Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments; all other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Example 1

As shown in fig. 1-2, a hollow end portion shaft head plug for ultra-long shaft machining comprises a connecting disc 1, a blocking body 2 and a loading and unloading prism 3, wherein the blocking body 2 is arranged on one side of the connecting disc 1, the loading and unloading prism 3 is arranged on the other side of the connecting disc 1, threads are arranged on the blocking body 2, the connecting disc 1, the blocking body 2 and the loading and unloading prism 3 are coaxially arranged, the loading and unloading prism 3 is of a polygonal prism-shaped structure, a center hole 4 is formed in the center of the top surface of the loading and unloading prism 3, and two mounting holes 5 corresponding to threaded holes in the end face of a machining shaft are formed in the connecting disc 1. The mounting hole 5 is an arc waist-shaped through hole taking the axis as the center.

The embodiment is correspondingly applicable to the end face A of the super long shaft as shown in fig. 6, two larger threaded holes are formed in the center periphery of the end face A, two corresponding waist-shaped holes are formed in the connecting disc 1, and after the screwing-on and screwing-off prism 3 enables the plug body 2 to rotate into the end face center hole of the super long shaft, the connecting disc 1 after being screwed in a threaded connection cannot determine the relative position with the threaded holes in the periphery of the end face, so that the adaptability of the waist-shaped mounting hole 5 is stronger.

Example two

As shown in fig. 1 and 3, the structure of the present embodiment is the same as that of the first embodiment except that eight small screw holes are provided at the center periphery thereof in order to be applied to the end face B of the super long shaft as shown in fig. 6, so that eight corresponding waist-shaped holes are provided on the connection disc 1.

Example III

In the processing and using process, the center can be abutted against the center hole 4 to be rubbed continuously, so that the center hole 4 is the most easily worn part, and in order to ensure the accuracy of a processing center line, when the center is worn to a certain extent, the plug needs to be replaced again, the material loss is increased, and because the main body structure of the plug needs to be matched with the threads of the center hole of the ultra-long shaft head, the processing is also needed, and the time cost is put into a certain extent, as shown in fig. 4-5, the center of the end face of the loading and unloading prism 3 is provided with a disc cavity, a replacement disc 6 is arranged in the disc cavity, the replacement disc 6 is made of high wear-resistant steel, the center hole 4 is arranged at the center of the outer end face of the replacement disc 6, and each side face of the loading and unloading prism 3 is provided with a counter bore and is fixedly connected with the replacement disc 6 through a connecting bolt 7. When the center hole 4 is worn to a certain extent, the plurality of connecting bolts 7 are loosened, the replacement disc 6 is replaced, the plug can be put into use again, the main body part of the plug does not need to be replaced, and the material loss cost and the time input cost are greatly reduced.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model.
