Model utility content
The purpose of this utility model is to provide a kind of axle limit structure, and in order to solve in prior art after limiting board distortion, axle coordinated easy inefficacy to there is the technical problem of potential safety hazard with limiting board structure block.The purpose of this utility model is also to provide a kind of long-spiral drilling machine using this axle limit structure.
For achieving the above object, the utility model adopts following technological scheme:
Axle limit structure, comprise for installing axle in the base and for only coordinating with described axle bumper with the limiting board to axle stop limit, described axle be provided with described limiting board adaptation for installing described limiting board to carry out the mounting hole of spacing stop to axle or for coordinating the groove to carry out spacing stop to axle with described limiting board block, described mounting hole or groove have for coordinating with the upper side of limiting board, downside block with the sidewall stoping axle to rotate.
Described axle is provided with the groove for coordinating with described limiting board block, described in limiting stopper, groove is positioned on the end face of axle.
Described groove runs through along the diametric(al) of axle, and limiting board two ends are provided with the perforation for connecting base.
The corresponding attachment hole be provided with for installing link on described bottom portion of groove and limiting board.
Long-spiral drilling machine, comprise axle limit structure and base, described axle limit structure comprises for installing axle in the base and for only coordinating with described axle bumper with the limiting board to axle stop limit, described axle be provided with described limiting board adaptation for installing described limiting board to carry out the mounting hole of spacing stop to axle or for coordinating the groove to carry out spacing stop to axle with described limiting board block, described mounting hole or groove have for coordinating with the upper side of limiting board, downside block with the sidewall stoping axle to rotate.
Described axle is provided with the groove for coordinating with described limiting board block, described groove is positioned on the end face of axle.
Described groove runs through along the diametric(al) of axle, and described limiting board two ends are provided with the perforation for connecting base.
The corresponding attachment hole be provided with for installing link on described bottom portion of groove and limiting board.
Advantageous Effects of the present utility model is: setting and the hole of limiting board adaptation or the end face of axle arrange the groove with limiting board adaptation in the cylndrical surface of axle, limiting board is arranged in mounting hole or groove, when axle rotates, the upper and lower end face of limiting board coordinates to stop axle to rotate with the upper and lower sidewall block of mounting hole respectively, increase the area of contact of limiting board and axle, even if limiting board formation abrasion, limiting board can not depart from groove, adds the stop reliability of limit structure.
The end face of axle arranges groove, is convenient to Milling Process, and less in the radial strength impact of end face machined grooves on axle of axle.
Further analysis, groove runs through along the diametric(al) of axle, and limiting board two ends have perforation, and when limiting board is installed, two ends are connected on base, increase the area of contact of limiting board and groove bottom land, coordinates reliable.
Further, on the bottom land of groove and limiting board, correspondence establishes attachment hole, and axle is connected by link with connecting plate, carries out spacing to the axis of axle.

Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is described in detail.
A kind of embodiment of the utility model axle limit structure, as shown in Figure 3,4, comprise axle 1, limiting board 3, described axle 1 end face is provided with groove 12, groove 12 is along shaft diameter direction through-shaft 1 end face, groove 12 has upper side wall, lower wall two sidewalls, the bottom land of groove 12 and the corresponding position of limiting board 3 are provided with the attachment hole for installing link, the attachment hole of bottom land is tapped hole 13, described link is connecting bolt 5, be convenient to the dismounting of axle and limiting board, limiting board 3 is connected on axle 1 by connecting bolt 5.Described limiting board 3 two ends are provided with perforation, be coated with in perforation bolt 2 with by bolt releasable connection on base.
