Abstract
The utility model provides a synchronous bolt tightening device which comprises a circular table. A driver is fixed at the center of the circular table. A driving shaft of the driver is arranged on the central axis of the circular table. A master gear is fixed on the driving shaft. Driven gears meshed with the master gear are distributed uniformly around the driving shaft. The number of the driven gears is equal to that of the screw holes in an end cap. One end of the shaft of each driven gear is arranged on the circular table, and a thread sleeve is arranged at the other end of the shaft of each driven gear. The synchronous bolt tightening device can fasten screws on the end cap conveniently and rapidly.
Description
Affiliated technical field
The utility model relates to the plant equipment field, especially, is the synchronous fastener of a kind of bolt.
Background technology
In the assembling of hydraulic cylinder end cap, press assembly technical requirement, each screw on the end cap is screwed onto more than half degree of depth in order, tighten in order again, the end cap position of assembling is more correct like this.But assembling has expended great amount of time like this, and loaded down with trivial details.
Summary of the invention
To the problems referred to above, the purpose of the utility model is to provide a kind of bolt synchronous fastener, and the synchronous fastener of this bolt can be crossed the screw that fastening end conveniently covers.
The scheme that the utility model technical solution problem is adopted is: the synchronous fastener of this bolt comprises a round platform; A driver is fixed in said round platform center; The driving shaft of said driver is on the central shaft of round platform; Be fixed with a master gear on the said driving shaft, on average be evenly equipped with the driven gear that is meshed with master gear around the said master gear, the quantity of said driven gear equates with screw quantity on the end cap; One end of the axle of said driven gear is assemblied on the round platform, and the other end of the axle of said driven gear is fixed with swivel nut.
Further, be handled easily, two action bars are arranged on the said round platform.
Further, being connected through screw thread of axle of said swivel nut and driven gear fixed, and is convenient for changing the swivel nut of different size.
Further, said swivel nut can hold screw for the magnetization swivel nut.
Further, said driver is an air motor, and the air motor perfect heat-dissipating is not damaged during overload.
The beneficial effect of the utility model is: said driver drives master gear; Master gear drives a plurality of driven gears; The screw that said driven gear driving swivel nut opposite end covers carries out fastening synchronously; Synchronously fastening with respect to single fastening saving time, and screw is tightened simultaneously and is made end cap be fixed on the optimum position.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the synchronous fastener of this bolt.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
In the embodiment shown in fig. 1; The synchronous fastener of this bolt comprises a round platform 1, and a driver 12 is fixed in said round platform center, and the driving shaft 11 of said driver 12 is on the central shaft of round platform 1; Be fixed with a master gear 2 on the said driving shaft 11; 6 driven gears 3 that mesh with master gear 2 of average cloth around the said master gear 2, an end of the axle of said driven gear 3 is assemblied on the round platform 1, and the other end of the axle of said driven gear 3 is fixed with swivel nut 31.
The synchronous fastener of above-mentioned bolt is handled easily, and two action bars 13 are arranged on the said round platform 1.
The synchronous fastener of above-mentioned bolt, being connected through screw thread of axle of said swivel nut 31 and driven gear 3 fixed, and is convenient for changing the swivel nut of different size.
The synchronous fastener of above-mentioned bolt, said swivel nut 31 can hold screw through magnetization.
The synchronous fastener of above-mentioned bolt, said driver 12 is an air motor, the air motor perfect heat-dissipating is not damaged during overload.
The method of operating of the above-mentioned synchronous fastener of bolt is: handle two action bars 13 six swivel nuts 31 are entangled six screws; Again six screws are aimed at 6 screws that circumferentially are uniformly distributed with on the end cap; Start air motor; Said air motor drives master gear 2, and master gear 2 drives six driven gears 3, and six said driven gears 3 drive the screw that swivel nuts 31 opposite ends cover and carry out fastening synchronously; Synchronously fastening with respect to single fastening saving time, and screw is tightened simultaneously and is made end cap be fixed on the optimum position
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
