Abstract
The utility model discloses a gear workpiece fixing device which comprises an axle, a base, an axle flange sheathed on the axle, a lower cover and a gear workpiece, wherein one end of the axle is fixedly connected on the base, and the other end thereof extends out of the lower cover; the gear workpiece is sheathed on the axle; an upper cover is pressed on the gear workpiece; the axle flange is contained in the lower cover and pushes against the inner wall of the lower cover; and the lower cover and the axle flange both push against the base. The axle flange is improved, thus remarkably reducing the length and width of the axle, reducing the processing difficulty of the axle, and improving the positioning precision of the axle.
Description
Technical field
The utility model relates to the Gear Processing field, relates in particular to a kind of fixture that is used for fixing gear to be processed.
Background technology
Mill teeth adds man-hour, often needs gear workpiece to be processed is fixed on the processing pedestal, processes then.In the prior art, as shown in Figure 1, the gear Work fixing device often comprises following several sections: axle center 5, base 7, axle center flange 6, lower cover 4, during concrete the assembling, as shown in Figure 2, the axle center links together lower cover 4, axle center flange 6, base 7, and base 7 is fixed on the operating desk or on the firm ground, one conversion pull bar 8 one ends extend in the base 7, are spirally connected with the end in axle center 5; The other end in axle center 5 stretches out lower cover 4, gear workpiece 3 to be processed is inserted in axle center 5, gear workpiece 3 is provided with one and is used for fixing gear workpiece 3 and does not make its cover that rocks 2, one loam cake 1 is set on the axle center 5, just gear workpiece 3 to be processed can be fixed on the axle center by such fixed form, process then.
In the practice, there are the following problems to find such fixture:
1, the length in axle center is oversize, and nearly four meters length strengthens the difficulty of processing in axle center, and in order to closely cooperate with each parts, is provided with a plurality of step surfaces on the axle center, same like this processing and the intractability that has increased the axle center;
2, the length in axle center is very long, causes the installation in axle center and location relatively more difficult.
The utility model content
The purpose of this utility model provides a kind of gear Work fixing device, by the axle center flange is improved, thereby the length in axle center and width is all significantly reduced, and has reduced the difficulty of processing in axle center, has improved the axle center locating accuracy.
In order to achieve the above object, the utility model adopts following technical scheme:
A kind of gear Work fixing device, comprise an axle center, a base, be set in axle center flange, lower cover and gear workpiece on the axle center, one end in described axle center is fixed on the base, the other end in described axle center stretches out lower cover, one gear workpiece is set on the axle center, one loam cake is pressed on the described gear workpiece, described axle center flange be located in the lower cover and with lower cover inwall butt, described lower cover and described axle center flange all are connected on the base.
Further, be provided with a high-base that adds that is set on the axle center between described base and the described lower cover, described high-base one end that adds is connected on the described base, and the other end is connected to and covers under described; One conversion pull bar, one end stretches into described base and the described high-base that adds, and is screwed onto an end in axle center.
Further, be connected with an auxiliary flange coaxial on the flange of described axle center with the axle center flange.
The beneficial effects of the utility model are: the utility model is by being improved the structure of axle center flange and lower cover, the size of its axle center flange integral body is dwindled, like this, when originally the step that is provided with by axle center flange itself is connected to the lower cover bottom, because the step of axle center flange has certain length, the corresponding like this length in axle center that caused is elongated, the axle center flange directly is installed with in lower cover now, and with the inwall butt of lower cover, be that the axle center flange has been arranged in the inner chamber of lower cover all over, thereby made the contraction in length in axle center, because the axle center flange has been arranged in the lower cover, the width in axle center has also shortened dramatically like this, also there is no need to be provided with step surface again simultaneously, thereby greatly reduce the difficulty and the precision of processing, saved material.Because axle center contraction in length, width have also shortened, also more smooth and easy with cooperating between each parts, so the installation in axle center and orientation ratio are faster.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is elaborated:
Fig. 1 is the STRUCTURE DECOMPOSITION schematic diagram of prior art fixture;
Fig. 2 is the structure assembling back schematic diagram of prior art fixture;
Fig. 3 is the STRUCTURE DECOMPOSITION schematic diagram of the utility model fixture;
Fig. 4 is the structure assembling back schematic diagram of the utility model fixture;
The specific embodiment
As Fig. 3 is the STRUCTURE DECOMPOSITION schematic diagram of the utility model fixture; Fig. 4 is the structure assembling back schematic diagram of the utility model fixture; A kind of gear Work fixing device, comprise an axle center 51, a base 7, be set in axle center flange 61, lower cover 4 and gear workpiece 2 on the axle center 51, one end in axle center 51 is fixed on the base 7, the other end in axle center 51 stretches out lower cover 4, one gear workpiece 2 is set on the axle center 51, one loam cake 1 is pressed on the gear workpiece 3, and a cover 2 is arranged between loam cake 1 and the gear workpiece 3 simultaneously, and cover 2 is mainly used in the fixed gear workpiece does not make it rock.Axle center flange 61 be located in the lower cover 4 and with lower cover 4 inwall butts, be connected with an auxiliary flange 10 coaxial on the axle center flange 61 with axle center flange 61, being provided with one between base 7 and the lower cover 4 is set in and adds high-base 9 on the axle center 51, add high-base 9 one ends and be connected on the base 7, the other end is connected on the lower cover 4; Lower cover 4 all is connected to axle center flange 61 and adds on the high-base 9.One conversion pull bar, 81 1 ends stretch into base 7 and add high-base 9, are screwed onto an end in axle center 51.
Those skilled in the art will recognize that, the above-mentioned specific embodiment is exemplary, be in order better to make those skilled in the art can understand this patent, can not be interpreted as it is the restriction that this patent is comprised scope, so long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope that this patent comprises.
