Embodiment one
As shown in Figure 1, a kind of more bolt synchronous fastening tools include internal gear 1, pinion gear 3 and bolt collar 5.Wherein, interior
The gear teeth of gear 1 set within it on circle, and the gear teeth of pinion gear 3 are arranged in its outer circle, the tooth profiles of internal gear 1 and distribution and
The tooth profiles of pinion gear 3 and distribution match, and pinion gear 3 is engaged with its external internal gear 1.When internal gear 1
When rotation, the multiple pinion gears being engaged in the same internal gear 1 can be rotated synchronously with the rotation of internal gear 1.Due to
The gear teeth of internal gear 3 are arranged in inner circle, correspondingly, the pinion gear 3 engaged should be located in the inner circle of internal gear,
Not only make the structure of entire fastening tool more compact in this way, but also all internal gears are protected in external tooth, does not allow
Easily it is damaged.Bolt collar 5 can use general utility tool commonly used in the prior art, and its underpart is equipped with to be needed to fasten for covering
Bolt on bolt connecting hole, the shape of bolt connecting hole needs and the exterior contour of bolt matches, so that bolt collar 5
When rotation, it is able to drive the bolt synchronous rotation of set inside.The top of bolt collar 5 is equipped with for connecting the small of pinion gear 3
Gear connection structure 51.It is also correspondingly provided in pinion gear 3 and connect knot with the bolt collar 5 that pinion gear connection structure 51 matches
Structure 31, enable pinion gear 3 coaxially connected with bolt collar 5 together with, when pinion gear 3 rotate when be able to drive bolt collar
5 rotate coaxially.Specifically, bolt collar 5 and pinion gear 3 can be solid by threaded connection in the prior art, grafting, snapping etc.
Determine connection type to link together.3 plug connection of bolt collar 5 and pinion gear is used in the present embodiment, to facilitate their company
It connects and dismantles.As shown in Fig. 2, bolt collar connection structure 31 can be the connector for being co-axially located at the end of pinion gear 3, it is small
Gear connection structure 51 is the link slot for being co-axially located at the end of bolt collar 5.Or opposite structure, spiral shell can also be used
Bolt sleeve connection structure 31 is the link slot for being co-axially located at the end of pinion gear 3, and pinion gear connection structure 51 is coaxial arrangement
Connector in the end of bolt collar 5.Connector and link slot are mutually matched and circumferentially limit, for example, connector is transversal
Face is that the cross section of the polygons link slots such as rectangular perhaps triangle is also correspondingly the polygons such as rectangular or triangle, with
Realize circumferential limit.Or the cross section of connector may be designed in round and then a restriction protrusion be arranged in its outer surface,
The cross section same design of link slot is corresponding round then in one corresponding limit recess portion of its outer surface setting.
Internal gear can use manual actuation or electric drive, for example, can the outer wall of internal gear symmetrically set to
Two operating sticks realize the same of nut for moving operation handle along direction pivots clockwise or counter-clockwise as operation handle 4
Step fastening or synchronous disassembly.Can also in the coaxially connected driving motor in the end of internal gear, open driving motor it is positive or
Person reversely rotates the synchronous fastening or synchronous disassembly that nut can be realized.
Above-mentioned more bolt synchronous fastening tools of the present embodiment can be used for pipe flange, blank flange and other be in same
The synchronous fastening and disassembly of multiple bolts on heart circle.When in use, the distribution face of the bolt of fastening is synchronized as needed
Long-pending and quantity selects the internal gear of suitable size with appropriate number of pinion gear: the quantity of pinion gear is synchronous as needed to be fastened
Bolt quantity depending on, such as there are 4 bolts need synchronous fastening on a flange, then need 4 pinion gears；Internal gear size needs
Meeting can be accommodated in the inner all pinion gears and engage with each pinion gear.After select pinion gear and internal gear
It operates as follows:
Step S1, by 5 sets of bolt collar on needing the multiple bolts of fastening/disassembly.
Step S2 installs pinion gear on each bolt collar.The bolt collar connection structure of pinion gear is directed at spiral shell downward
The pinion gear of bolt sleeve, and be plugged in together.
Step S3, installation internal gear engage it with each pinion gear installed in step S2.From top to bottom by internal gear
It covers around pinion gear, and is engaged with each pinion gear.
Step S4, driving internal gear rotation is to fasten/dismantle multiple bolts.External torque is applied to internal gear, internal gear
Pinion gear is passed torque to, drives pinion gear to rotate together with bolt collar, by fastening bolt under the action of bolt collar
Also rotational fastener together.Since all pinion gears engaged with internal gear rotate synchronously, it is ensured that all by fastening bolt
All obtain uniformly synchronous fastening.
Preferably, internal gear 1 can be spliced with two internal gear half portions 11 in Fig. 1.Gear half portion 11 is interior
Two semi-ring cylinders that circumferential wall is toothed around, the both ends that they are mutually butted are equipped with bolt hole, and fastening bolt 2 is passed through two
