Description
Technical field
The utility model relates to a kind of plastic gear and metal gear fixing tool, and it, for the plastic gear in non-for breaker of plastic casing energy storage type operating mechanism and metal gear are combined into gear train, belongs to breaker processing and manufacturing technical field.
Background technology
Along with economic development, the living standard of people in continuous raising, people to power supply quality and quantity also in continuous raising.While the demand of breaker of plastic casing improves constantly, breaker of plastic casing use the life-span of annex also in continuous raising.So just there is higher requirement to the seed output and quality of breaker of plastic casing non-energy storage type operating mechanism.Most of gear train in present breaker of plastic casing non-energy storage type operating mechanism is combined by metal gear, but find in actual use, some position can replace metal gear with plastic gear completely, and can not product quality be had influence on, so not only greatly can save production cost, and can enhance productivity.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provide a kind of plastic gear and metal gear fixing tool, its structure is simple, flexible and convenient to use, can installation time be shortened, improve efficiency of assembling, save production cost, improve security during assembling.
Technical scheme according to the utility model provides: plastic gear and metal gear fixing tool, is characterized in that: comprise base, guide rod, spring, movable pressing board and electric iron; Described guide rod is vertically fixed on base, and described movable pressing board is provided with pilot hole, and movable pressing board to be assemblied on guide rod by pilot hole and liftable moves; Described spring housing is on guide rod, and spring upper end connects movable pressing board, and lower spring end connects base; Described movable pressing board center is provided with installing hole, for placing the gear train by plastic gear and metal gear pressing in described installing hole; Described electric iron is arranged on immediately below described installing hole, and the top of electric iron is provided with the locating slot suitable with plastic gear lower end.
As further improvement of the utility model, the pilot hole on described movable pressing board is built with the linear bearing coordinated with guide rod.
the utility model compared with prior art, has the following advantages:the utility model structure is simple, flexible and convenient to use, greatly can shorten the installation time of plastic gear and metal gear, improves efficiency of assembling, saves production cost, and improves security during assembling.

Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in the figure: the plastic gear in embodiment and metal gear fixing tool are primarily of compositions such as base 1, guide rod 2, spring 3, movable pressing board 4, linear bearing 5 and electric iron 6.
As shown in Figure 1 and Figure 2, described guide rod 2 is vertically fixed on base 1, and described movable pressing board 4 is provided with pilot hole, and movable pressing board 4 to be assemblied on guide rod 2 by pilot hole and liftable moves; Described spring 3 is enclosed within guide rod 2, and spring 3 upper end connects movable pressing board 4, and spring 3 lower end connects base 1; Described movable pressing board 4 center is provided with installing hole, for placing by the gear train of plastic gear 7 with metal gear 8 pressing in described installing hole; Described electric iron 6 is arranged on immediately below described installing hole, and the top of electric iron 6 is provided with the locating slot 6a suitable with plastic gear 7 lower end.
As shown in Figure 1, in order to improve assembly precision, the pilot hole on described movable pressing board 4 is built with the linear bearing 5 coordinated with guide rod 2.
During concrete use, by plastic gear 7 with metal gear 8 according to being pressed into gear train (plastic gear 7 and metal gear 8 pass through splined) shown in Fig. 2, Fig. 3, then be put into by gear train in the installing hole on movable pressing board 4, movable pressing board 4 is connected with the pressure head on press; Start press, the pressure head of press drives movable pressing board 4 together with gear train toward pressing down, gear train is pressed in electric iron 6, the lower end correspondence of plastic gear 7 enters in the locating slot 6a at electric iron 6 top, electric iron 6 heating power, the part spline softening transform that plastic gear 7 is exposed, thus plastic gear 7 and metal gear 8 are combined fixing.The pressure head of then press is lifted, and movable pressing board 4 and gear train are upspring by spring 3, complete assembling.
