Abstract
The utility model relates to a fast-removal repeated-used counterbore shaft belonging to a fast-removal repeated-used counterbore shaft which is used by the mechanical structure with a counterbore. The utility model mainly solves the technical difficulties of that the prior counterbore shaft is difficult to be disassembled, the parts are damageable and can not be repeatedly used. The utility model is characterized in that the fast-removal repeated-used counterbore shaft includes a nut, a counterbore shaft body and a stretching pin; the center of the counterbore shaft body is provided with an internal cone pin hole; an open gas is axially arranged along the counterbore shaft body; the stretching pin is provided with a thread section which is connected with the nut, a stretching pin which is combined with the internal cone pin hole, and a torsion trough arranged between the thread section and the stretching pin body; the stretching pin is arranged in the pin hole of the counterbore shaft body; the nut is arranged on the thread section of the stretching pin. The utility model has the advantages of that the removal is easy, the parts can not be damaged and the usage can be repeated, etc.
Description
Technical field
The utility model relates to a kind of Quich-dismounting repeated-use hole-sinking shaft, and it belongs to a kind of fast disassembly type and reusable counterbore axle that counterbore mechanical structure is used that have.
Background technique
At present, in the mechanical coupling structure, often adopt the counterbore axle of interference fit or transition fit to connect.Make in this way the parts that connect when dismounting, tend to part of damage or damage the counterbore axle and they could be dismantled.Block bearing if any rail tunnel stacker pallet fork both sides adopts the said structure form exactly.Because the block bearing of rail lane stacker pallet fork is an easily damaged parts, when damage of bearings need be changed,,, also can't retract the counterbore axle even take disruptive method with the bearing breakage because the counterbore axle cooperates tension to dismantle with counterbore.Shortcomings such as therefore, existing counterbore axle exists the dismounting difficulty, component are fragile and can not reuse.
Summary of the invention
The purpose of this utility model is that to solve dismounting difficulty, component that existing counterbore axle exists fragile and can not reusable technological difficulties and provide a kind of dismounting easily, not damage component and can reusable Quich-dismounting repeated-use hole-sinking shaft.
The utility model for the technological scheme that solves above-mentioned technological difficulties and adopt is: Quich-dismounting repeated-use hole-sinking shaft, it comprises nut, wherein: it also comprises counterbore axis body and tensioner pin, the center of described counterbore axis body has an inner conical pin hole, the open slit that is axially arranged with along the counterbore axis body, described tensioner pin has a thread section that is connected with nut, the one tensioner shank that combines with the inner conical pin hole, and be located at torsional channel between thread section and the tensioner shank, the tensioner pin is contained in the pin hole of counterbore axis body, and nut is contained on the thread section of tensioner pin.
The tapering of described inner conical pin hole is 1: 50.
The width of described torsional channel is 1.5mm～2mm.
Because the utility model has adopted the counterbore axle of above-mentioned band tensioner pin, not only can dismantle smoothly, and is also reusable.Therefore, compare, have dismounting and easily, do not damage component and advantage such as can reuse with background technique.

Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, Quich-dismounting repeated-use hole-sinking shaft in the present embodiment, it comprises nut 1, wherein: it also comprises counterbore axis body 2 and tensioner pin 3, the center of described counterbore axis body 2 has an inner conical pin hole 5, the open slit 4 that is axially arranged with along counterbore axis body 2, described tensioner pin 3 has a thread section 6 that is connected with nut 1, the one tensioner shank 8 that combines with inner conical pin hole 5, and be located at torsional channel 7 between thread section 6 and the tensioner shank 8, tensioner pin 3 is contained in the pin hole of counterbore axis body 2, and nut 1 is contained on the thread section of tensioner pin 3.
The tapering of above-mentioned inner conical pin hole 5 is 1: 50.The tapering of tensioner shank 8 is identical with the tapering of inner conical pin hole 5.
The width of above-mentioned torsional channel 7 is 1.5mm.The diameter of torsional channel 7 is determined by tensioner pin 3 required moments of torsion.The width of above-mentioned torsional channel 7 can also be selected arbitrarily between 1.5mm～2mm, promptly can also elect 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2mm etc. as.
As shown in Figure 6, taperings such as the inner conical pin hole of the utility model counterbore axle and tensioner pin 3 and inner conical pin hole one side shaft are to opening, tensioner pin 3 can be packed in the pin hole smoothly, when part 9 that counterbore axis body 2 will be installed is installed on another part 10 and behind the location, screw nut 1, make tensioner pin 3 with counterbore axis body 2 tensioners and be fixed in the counterbore.After reaching prescribed torque, the thread section of tensioner pin 3 disconnects from torsional channel, has just finished assembling.When need are dismantled, can axially knock tensioner pin 3, it is withdrawed from from pin hole, counterbore axis body 2 can become flexible, and unloads smoothly.Behind the renewal part, can continue to use.
Claims (3)
