Abstract

The utility model discloses an improved gear workpiece fixing device, which comprises a shaft core, a base, a shaft core flange, a lower cover and a gear workpiece. The shaft core flange is sheathed on the shaft core. One end of the shaft core is fixedly connected on the base and the other end of the shaft core extends out of the lower cover. The gear workpiece is sheathed on the shaft core. An upper cover is arranged on the gear workpiece. The shaft core flange is arranged in the lower cover and is propped against the inner wall of the lower cover. The lower cover and the shaft core flange are propped against the base. Through the improvement to the lower cover and the shaft core flange, the utility model has the advantages that the length and the width of the shaft core are obviously reduced, the machining difficulty of the shaft core is reduced and the positioning accuracy of the shaft core is improved.

Description

A kind of improved gear Work fixing device

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 improved gear Work fixing device, by lower cover and axle center flange are 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 improved gear Work fixing device, comprise an axle center, one base, be set in the axle center flange on the axle center, lower cover and gear workpiece, 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 lower cover is a bowl-type, a port of described lower cover vertically is connected on the gear workpiece, the another port vertically is connected on the base, 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, described conversion pull bar is connected with the axle center by a pull bar adapter.

The beneficial effects of the utility model are: the utility model is by being improved the structure of axle center flange and lower cover, flange its whole size in axle center 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 just there is no need to be provided with step surface again simultaneously, thereby greatly reduce the difficulty and the precision of processing, saved material.In order further to reduce the length in axle center, this patent is improved the lower cover structure simultaneously, makes traditional annulus cylindricality into bowl-type, and promptly the lower cover middle transitional stage has been made the inclined-plane into by straight tube, thereby the height of lower cover is greatly reduced, the length in axle center has been shortened once again.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;
