Embodiment
In Fig. 1 and 2; Can see that shaft 2 is designed to the carrying-handle (not shown), described axle mechanically is connected with Spin Control axle 1 through mechanical splice 3, and said axle belongs to circuit-breaker; The sort of as described in french patent application FR1000817, and contact that can operating instrument.
Mechanical splice 3 is designed to carry out the transmission of angular turn between axle 1,2, gives the certain flexibility of described mechanical connection simultaneously, make between the axis of two axles 1,2 possible misalignment or tilt can be able to compensation.
Mechanical splice 3 comprises a disk 5; It comprises the flexuose opening 4 on the end portion 6 that can be installed in Spin Control axle 1; This end portion demonstrates the flexuose outer shape corresponding with the opening of aforesaid disk 54, and said disk 5 is designed to be pressed on the edge 7 with Spin Control axle 1 one.
Joint 3 comprises that also one has second parts 8 of common tubular form, and it comprises tubular opening 8b, and the end 8a in its end also comprises the corresponding flexuose shape of flexuose shape with the end 6 of aforesaid Spin Control axle.Second parts 8 also are included in the tubular opening 8d at the 8c place, end that front end is relative with it; It also demonstrates the flexuose shape; The end 2a of the handle supporting axle 2 that this shape can be received in these parts to present the rectangular cross-section in the cross section; So that can be at Spin Control axle 1, the rotation transmission between mechanical splice 3 and the handle supporting axle 2 becomes possibility.Second parts 8 also comprise roughly the edge 9 in its mid-length; It comprises the post piece (studs) that can receive spring 10; Spring 10 is designed to be pressed on the edge 9 through a wherein end 10a of its end, and is pressed on the above-mentioned disk 5 through its opposite end 10b.
This assembling device also comprises screw 11; Screw 11 can insert in second parts 8 of mechanical splice 3 through its threaded end 11b; Through it be positioned on the side identical with handle supporting axle 2 and be designed to the side that spiral gets into the Spin Control axle; Screw head 11a is designed to be pressed on the internal circular disc 12, and this disk belongs to second parts 8, and comprises for this purpose and the opening that is provided with.
According to the present invention with shown in Fig. 1-6, be designed to receive the parts of screw, promptly the Spin Control axle 1; Comprise [13; It has only attacked screw thread on certain-length, and comprises that in the bottom in this hole this part is designed to receive the end of screw than the part 14 of this hole remaining part larger diameter.
Axle is processed with side opening 15 through molded manufacturing on Spin Control axle 1, this opening be positioned at towards enlarged by the part 14 of boring or brill, and be designed to allow the parts of mould to pass through, it is molded that this mould can make the part of bigger diameter be able to.
The assembling of diaxon 1,2 is passed through according to assembling device of the present invention in explanation below with reference to accompanying drawings.
At first, the disk 5 that belongs to mechanical splice 3 is installed around the end 6 of axle 1, and tubulose second parts 8 of said joint 3 and the aforesaid spring 10 that is placed between the disk 5 and second parts 8 are installed together.
Then, screw 11 inserts second tubular part 8, and the helical thread portion 13 that then screws in Spin Control axle 1 up to the end of this screw against the blocked part that the diapire 13a by the hole forms.In this position, screw head 11a is pressed against on one of them 12a on surface of interior disk 12 of second parts of joint, and the parts of back are biased through spring 10 and are resisted against on the screw head.Also in this position, functional clearance j has been held between the end 6 of the surperficial 12b of the interior disk 12 of second parts 8 of joint and Spin Control axle.This gap j is able to against the blocked part on the planomural 13a of the bottom that is formed on the hole produce through set screw 11, and it makes joint 3 can be tightened on the end of Spin Control axle.This gap j can make the axis of Spin Control axle 1 and any misalignment and the inclination between the handle supporting axle 2 be compensated.
Therefore assembling device is achieved through the present invention, thus, can be able to accurately implement with in order to guarantee the gap between screw head and helical thread portion in screw end and the backstop that receives the screw 11 between the bottom in hole of this screw.Because except when screw is during against the blocked part, screw-down torque is low and constant, the assembling of being implemented is easy.When implementing manually to tighten, the detection of blocked part is easy.This scheme also can be used the screw of standard, and tapping easily.In fact the diameter than tapping is big for the diameter of bottom, hole, there is no need tap to the end, as long as increase diameter to guarantee that screw can be against the blocked part that is formed by the bottom, hole.
Through simple scheme in the industry, the invention solves this problem, be in the bottom in hole to be that screw forms accurate blocked part.In order to realize this purpose, in fact the bottom in hole has to put down, and when axle passed through molded manufacturing, it can easily be realized, and can use non-special general screw.
The present invention advantageously is applied to the assembling of the Spin Control axle and the handle supporting axle of circuit breaker; Can also be applied even more extensively in any device; Have to be maintained at screw head in this device intermediate gap and comprise between the parts of shooting screw thread, if parts are through molded manufacturing.
The invention is not restricted in this explanation and the embodiment that illustrates, it provides the purpose that has been merely example.
On the contrary, the present invention extends to and comprises illustrated device all technical equivalents thing and combinations thereof, is able to implement if its combination is a spirit according to the present invention.
