Abstract
The utility model discloses a kind of tooth mill precision drive structure, comprise cover plate and mainshaft gear, also comprise a screw mandrel connecting rod be fixedly connected with described mainshaft gear through cover plate, one end of described screw mandrel connecting rod is fixedly connected with accurate lead screw, described accurate lead screw is provided with two accurate swivel nuts, described two accurate swivel nuts are fixedly connected with same swivel nut fixed base.By arranging two accurate swivel nuts on accurate lead screw, and become mutual restricting relation, thus better with engaging of accurate lead screw, and transmission is more accurate; Center thread spindle adopts two-part structure (accurate lead screw and screw mandrel connecting rod), and cost is lower, and change faster, efficiency is higher; Screw mandrel connecting rod adopts rolling type part to fix, and can make with the friction of cover plate less, operate more smooth and easy, part life is longer.
Description
Technical field
The utility model relate to a kind of tooth mill precision drive structure, belongs to screw thread process technical field.
Background technique
To screw rod grind one's teeth in sleep processing be operation very common in modern product production process.As shown in Figure 1, accurate lead screw 5 is monolithic construction to existing tooth mill drive mechanism, and the accurate lead screw processing cost for new argument is high, and coordinates for dry between accurate lead screw 5 with cover plate 1, and friction factor is large, easy to wear; End face uses the first screw 10 to fix, and degree of tightness degree of holding needs to regulate, and easily occurs loosening, rotate the situation had some setbacks in using; What more crucially existing driving mechanism adopts is the structure that single swivel nut coordinates accurate lead screw, and in Long-Time Service process, easily both back lashes increase, and affect the precision of transmission.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of tooth mill precision drive structure, is convenient to the accurate lead screw changing different thread parameter, and the precision of transmission is simultaneously higher.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is:
A kind of tooth mill precision drive structure, comprise cover plate and mainshaft gear, also comprise a screw mandrel connecting rod be fixedly connected with described mainshaft gear through how many cover plates, one end of described screw mandrel connecting rod is fixedly connected with accurate lead screw, described accurate lead screw is provided with two accurate swivel nuts, described two accurate swivel nuts are fixedly connected with same swivel nut fixed base.
Aforesaid a kind of tooth mill precision drive structure, it is characterized in that: be also provided with bearing base between described cover plate and described mainshaft gear, the both sides of described bearing base are provided with rolling bearing.
Aforesaid a kind of tooth mill precision drive structure, is characterized in that: described accurate lead screw is connected with described screw mandrel connecting rod by the second screw.
Aforesaid a kind of tooth mill precision drive structure, is characterized in that: described swivel nut fixed base is also provided with locating stud.
Aforesaid a kind of tooth mill precision drive structure, is characterized in that: fixing laterally across the 3rd screw of described screw mandrel connecting rod and described mainshaft gear, is longitudinally fixed by the 4th screw.
The beneficial effects of the utility model are: by arranging two accurate swivel nuts on accurate lead screw, and become mutual restricting relation, thus better with engaging of accurate lead screw, and transmission is more accurate; Center thread spindle adopts two-part structure (accurate lead screw and screw mandrel connecting rod), and cost is lower, and change faster, efficiency is higher; Screw mandrel connecting rod adopts rolling type part to fix, and can make with the friction of cover plate less, operate more smooth and easy, part life is longer.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing tooth mill drive mechanism;
Fig. 2 is the fractionation schematic diagram of a kind of tooth mill precision drive of the utility model structure;
Fig. 3 is the sectional view of a kind of tooth mill precision drive of the utility model structure.
Embodiment
Below in conjunction with Figure of description, the utility model is further described.
As shown in Figures 2 and 3, a kind of tooth mill precision drive structure, comprise cover plate 1 and mainshaft gear 4, also comprise a screw mandrel connecting rod 6 be fixedly connected with described mainshaft gear 4 through how many cover plates 1, one end of described screw mandrel connecting rod 6 is fixedly connected with accurate lead screw 5, described accurate lead screw 5 is provided with two accurate swivel nuts 7, described two accurate swivel nuts 7 are fixedly connected with same swivel nut fixed base 2.Center thread spindle adopts two-part structure, namely accurate lead screw 5 adds the structure of screw mandrel connecting rod 6, screw mandrel connecting rod 6 is fixedly connected on mainshaft gear 4, when needing the screw rod processing different thread parameter, only need by changing accurate lead screw 5, and re-assembly after being removed by whole device again, cost is lower, change faster, efficiency is higher; And by arranging two accurate swivel nuts 7 on accurate lead screw 5, and become mutual restricting relation, thus better with engaging of accurate lead screw 5, transmission is more accurate.
Also be provided with bearing base 3 between described cover plate 1 and described mainshaft gear 4, the both sides of described bearing base 3 are provided with rolling bearing 8, and screw mandrel connecting rod 6 adopts rolling type part to fix, and can make with the friction of cover plate 1 less, and operate more smooth and easy, part life is longer.
Described accurate lead screw 5 is connected with described screw mandrel connecting rod 6 by the second screw 11, realizes accurate lead screw 5 and the connection of screw mandrel connecting rod 6, be convenient to the screw mandrel changing different thread parameter by means of only the second screw 11.
Described swivel nut fixed base 2 is also provided with locating stud 9, is convenient to swivel nut fixed base 2 and is connected with slide block.
Described screw mandrel connecting rod 6 is fixed laterally across the 3rd screw 12 with described mainshaft gear 4, longitudinally fixed by the 4th screw 13, fixed by horizontal, longitudinal, ensure that the steadiness be connected between screw mandrel connecting rod 6 with mainshaft gear 4, not easily in use occur the situation that loosens.
In sum, a kind of tooth mill precision drive structure that the utility model provides, is convenient to the accurate lead screw changing different thread parameter, and the precision of transmission is simultaneously higher.
More than show and describe basic principle of the present utility model, major character and advantage.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is by appending claims and equivalent circle thereof.
