Abstract

The utility model discloses a tooth base fastener, including bottom plate, backup pad, tapered end, lock nut, screw hole, bar through -hole and tooth base, the bottom plate is rectangle and has offered the bar through -hole in the middle of the form, and is equipped with on the bottom plate and is square form backup pad, the round tooth base that is equipped with in the backup pad is fixed in the backup pad through the tapered end that tooth base both sides were equipped with, it makes that the bolt is vertical to be run through the tapered end to pass through lock nut fixed to have seted up the screw hole on the tapered end. This tooth base fastener has seted up the bar through -hole through in the middle of the bottom plate, can make the tapered end fasten the tooth base of different diameters to other fastener that have avoided needing to be changed have improved the efficiency of tooth base processing, and simple structure, low in manufacturing cost, fastening nature are good, are favorable to using widely.

Description

A kind of tooth base fastener

Technical field

The utility model relates to technical field of fastening, is specially a kind of tooth base fastener.

Background technology

Tooth base refers to that the gear blank before undressed profile of tooth is called tooth base, and the technique difference forming according to tooth base is divided into casting tooth base, forging gear stock and welding tooth base. Tooth base conventionally need to be fastening to it in process, thereby can meet processing needs, meanwhile, is also in order to ensure crudy. At present, existing tooth base fastener cost of manufacture is high, complex structure, be unfavorable for extensively promoting the use of, simultaneously, existing tooth base fastener is merely able to the tooth base of same diameter to carry out fastening, has so not only reduced operating efficiency, and has improved processing cost, therefore, we propose a kind of tooth base fastener.

Utility model content

The purpose of this utility model is to provide a kind of tooth base fastener, to solve the problem proposing in above-mentioned background technology.

For achieving the above object, the utility model provides following technical scheme: a kind of tooth base fastener, comprise base plate, gripper shoe, tapered end, locking nut, screw hole, strip through-hole and tooth base, described base plate is rectangle and offers strip through-hole in the middle of shape, and base plate is provided with and has a rectangular shape gripper shoe, the tapered end that the round tooth base that described gripper shoe is provided with is provided with by tooth base both sides is fixed in gripper shoe, offers screw hole and make bolt vertically run through tapered end to fix by locking nut on described tapered end.

Preferably, described gripper shoe is steel plate.

Preferably, described tapered end is symmetrical design.

Preferably, described locking nut is connected with bolt thread, and the nut of described bolt bottom is positioned at base plate bottom.

Preferably, the length that described strip through-hole is offered is with equaling floor length.

Compared with prior art, the beneficial effects of the utility model are: this tooth base fastener, by offering strip through-hole in the middle of base plate, can make tapered end carry out fastening to the tooth base of different-diameter, thereby avoid changing other fasteners, improved the efficiency of tooth base processing, and simple in structure, low cost of manufacture, tightness are good, are conducive to promote the use of.

Brief description of the drawings

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model plan structure schematic diagram.

In figure: 1 base plate, 2 gripper shoes, 3 tapered ends, 4 locking nuts, 5 screw holes, 6 strip through-holes, 7 tooth bases.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment. Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.

Refer to Fig. 1-2, the utility model provides a kind of technical scheme: a kind of tooth base fastener, comprise base plate 1, gripper shoe 2, tapered end 3, locking nut 4, screw hole 5, strip through-hole 6 and tooth base 7, described base plate 1 is rectangle and offers strip through-hole 6 in the middle of shape, and base plate 1 is provided with and has a rectangular shape gripper shoe 2, the tapered end 3 that the round tooth base 7 that described gripper shoe 2 is provided with is provided with by tooth base 7 both sides is fixed in gripper shoe 2, and on described tapered end 3, offering screw hole 5, to make bolt vertically run through tapered end 3 fixing by locking nut 4.

The utility model improves and is: this tooth base fastener, be steel plate by gripper shoe 2, be conducive to play the effect of support, extend the service life of gripper shoe 2, be symmetrical design by tapered end 3, can carry out fastening to tooth base 7, be conducive to keep equilibrium of forces, be connected with bolt thread by locking nut 4, the nut of described bolt bottom is positioned at base plate 1 bottom, be convenient to tooth base 7 and carry out dismounting man-hour adding, be conducive to the raising of operating efficiency, the length of offering by strip through-hole 6 is with equaling base plate 1 length, thereby can carry out fastening to diameter tooth base 7 within the specific limits.

Although illustrated and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that in the situation that not departing from principle of the present utility model and spirit and can carry out multiple variation, amendment, replacement and modification to these embodiment, scope of the present utility model is limited by claims and equivalent thereof.
