Resilient key assembling jig
Technical field
The present invention relates to the technical field of power system low-voltage electrical apparatus technological equipment, particularly relate to a kind of resilient key assembling jig.
Background technology
Guide plate is mainly first through on square shaft by existing dual power supply guiding parts assembling process, be clamped on bench vice, then resilient key one end is placed in square shaft locating hole, the resilient key other end is struck with hammer, make it be pressed into the hole of square shaft and the hole of guide plate, thus make guide plate and square shaft be fixedly connected into guiding parts.Adopt above method to assemble, handling part length consuming time, and guide part pieces complexity easily hurts hand, assembling safety does not ensure; In addition because guide recess is dark, easily guiding parts hindered by hammer.More than show, although traditional assembly technology is simple, length consuming time, assembling easily hinders hand, and fragile parts.
Summary of the invention
For traditional elastic pin assembling process length consuming time, the easily defect of loss parts, technical problem to be solved by this invention be to provide a kind of easy to operate, efficiency is high, can not damage the resilient key assembling jig of parts.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of resilient key assembling jig, comprises pedestal, also comprises the backing plate for positioning guiding plate and square shaft and pressing plate, described guide plate and square shaft are between backing plate and pressing plate, and described backing plate is fixedly connected with pedestal; Described pedestal is provided with support, and described support is provided with push rod, and described push rod can slide on the bracket; Described pressing plate is provided with the through hole for placing resilient key, and the hole on described through hole and square shaft, the hole on guide plate are on the same axis; Described pedestal is provided with the operating mechanism for handling push rod.
Described operating mechanism comprises eccentric wheel, and described eccentric wheel is positioned on support and also can rotates on support, and described eccentric wheel and push rod end thereof contacts, described eccentric wheel is provided with handle.
Described operating mechanism also comprises return mechanism, and described return mechanism comprises stage clip, and described compression spring sleeve is contained on described push rod, and described push rod is provided with spacer pin.
Described backing plate is provided with the groove suitable with the base plate of guide plate, is also provided with and the concave station of square shaft to adaptation.
Described pressing plate is provided with and two of guide plate notches that side plate is suitable, and while making described backing plate and pressing plate compress square shaft and guide plate, backing plate and pressing plate end face fit tightly.
Position corresponding with the hole on guide plate on the groove of described backing plate is provided with fluting, and the groove width of described fluting is greater than the diameter of resilient key.
The diameter of described push rod is greater than the diameter of resilient key.
The invention has the advantages that, easy and simple to handle, assembly technology is simple, and efficiency of assembling is high, and assembling safety is not easy to damage build-up member.

Detailed description of the invention
Fig. 1 and Fig. 4 is the structural representation of a kind of resilient key assembling jig of the present invention, comprise pedestal 1, also comprise the backing plate 2 for positioning guiding plate 11 and square shaft 12 and pressing plate 3, guide plate 11 and square shaft 12 are between backing plate 2 and pressing plate 3, and backing plate 2 is fixedly connected with pedestal 1; Pedestal 1 is provided with support 4, and support 4 is provided with push rod 5, and push rod 5 can slide on support 4; Pressing plate 3 is provided with the through hole 31 for placing resilient key 10, and through hole 31 and the hole on square shaft 12, hole on guide plate 11 are on the same axis; Pedestal 1 is provided with the operating mechanism for handling push rod 5.
Operating mechanism comprises eccentric wheel 9, and eccentric wheel 9 is positioned on support 4 and also can rotates on support 4, and eccentric wheel 9 and push rod 5 end thereof contacts, eccentric wheel 9 is provided with handle 8.Operating mechanism also comprises return mechanism, and return mechanism comprises stage clip 7, and stage clip 7 is sleeved on push rod 5, and push rod 5 is provided with spacer pin 6.The diameter of push rod 5 is greater than the diameter of resilient key 10.
Fig. 2 is the structural representation of the backing plate 2 of resilient key assembling jig, and backing plate 2 is provided with the groove 21 suitable with the base plate of guide plate 11, is also provided with and the concave station 22 of square shaft 12 to adaptation.On the groove 21 of backing plate 2, the position corresponding with the hole on guide plate 11 is provided with fluting 23, and the groove width of fluting 23 is greater than the diameter of resilient key 10.
Fig. 3 is the structural representation of the pressing plate 3 of resilient key assembling jig, and pressing plate 3 is provided with and two of guide plate 11 notches that side plate is suitable 32, and while making backing plate 2 and pressing plate 3 compress square shaft 12 and guide plate 11, backing plate 2 and pressing plate 3 end face fit tightly.
First support 4 is fixed on pedestal 1, then pressing plate 3 and backing plate 2 is placed in support 4 front lower place and is fixed on pedestal 1, be used for locating square shaft 12 and guide plate 11; Being enclosed within by stage clip 7 on push rod 5 and being sleeved on the hole of support 4, can slide axially up and down, and knock in push rod 5 by spacer pin 6, stage clip 7 mainly plays a part push rod 5 is resetted, and push rod 5 can facilitate resilient key 10 to insert in the through hole 31 of pressing plate 3 after resetting; Handle 8 is fixed on eccentric wheel 9, and eccentric wheel 9 is movably attached on support 4, to be beared down on one bar 5, resilient key 10 can be made to be pressed into square shaft 12 and guide plate 11 by eccentric wheel 9, thus completes guiding parts assembling.Eccentric wheel 9 and push rod 5 No. 45 steel quenching technicals are processed, to increase its intensity and hardness.
During use, first guide plate 11 is enclosed within square shaft 12, then inserted in the middle of backing plate 2 and pressing plate 3, and make the right side of square shaft 12 push up the concave station 22 of backing plate 2, make the hole of guide plate 11, the hole of square shaft 12 and the through hole 31 of pressing plate 3 are on the same axis, then resilient key 10 is inserted in the through hole 31 of pressing plate 3, then rotated by handle 8 clockwise, being rotated by eccentric wheel 9 makes push rod 5 resilient key 10 is pressed into square shaft 12 successively downwards, guide plate 11, be pressed onto till push rod 5 presses to go down, because the slipper diameter of push rod 5 puts the through hole 31 of resilient key 10 much larger than pressing plate 3.
After guiding parts assembles, when square shaft 12 and guide plate 11 affixed by resilient key 10 after, rotated by handle 8 inverse clock, push rod 5 gets back to original position under the reaction of stage clip 7.From the guiding parts of level taking-up above.
After adopting such structure, easy and simple to handle, assembly technology is simple, and efficiency of assembling is high, assembling safety, is not easy to damage build-up member.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
