Summary of the invention
The purpose of this utility model is to provide a kind of can locate, clamp convenience, not yielding to the link arm part fast and accurately fast, and can significantly save a large amount of centering positioning times, shorten process time significantly, improved the frock clamp body that is used for the asymmetric link arm of processing of operating efficiency.
For reaching the goal of the invention the technical solution adopted in the utility model be:
A kind of frock clamp body for the asymmetric link arm of processing, it is characterized in that: comprise a flat base, described base is provided with the first withdrawing hole that arranges according to the angle between asymmetric link arm three holes and pitch-row, the second withdrawing hole, the 3rd withdrawing hole, be connected with on the described base for first alignment pin that is used and second alignment pin with asymmetric link arm location, described first alignment pin, second alignment pin is separately positioned on the first withdrawing hole and the second withdrawing hole line, the outside of the second withdrawing hole and the 3rd withdrawing hole line, on the described base in the second withdrawing hole, the outside in the 3rd withdrawing hole all is connected with asymmetric link arm is pressed on pressing plate on the base.
Further, the pressing plate in described first alignment pin, second alignment pin and the outside, the second withdrawing hole all is located at the same outside in the second withdrawing hole.
Further, described pressing plate all is connected with base by screw.
Further, the pressing plate in the outside, described the 3rd withdrawing hole is higher than the pressing plate in the outside, the described second withdrawing hole.
The course of work of the present utility model is as follows:
1, according to the position of setting, correctly alignment pin, pressing plate are installed on the base.
2, put into the T type groove of lathe with T type nut, frock clamp body for the asymmetric link arm of processing described in the utility model correctly is installed in the workbench of lathe, play table with dial gauge and measure at two measuring basis faces for the frock clamp body of processing asymmetric link arm described in the utility model, make the frock clamp body for the asymmetric link arm of processing described in the utility model reach vertical, horizontal perpendicularity requirement.
3, described in the utility model for processing asymmetric link arm the frock clamp body install after, a side of asymmetric link arm against alignment pin, the tram of the asymmetric link arm of centering, general pressing plate is pressed on asymmetric link arm on the base end face again.
4, with three holes of the right title link arm of process tool bore, reaming gets final product.To be processed finishing unclamped pressing plate, takes out asymmetric link arm, and whole process has just been finished.
5, repeat above-mentioned steps 3 and step 4, next part is operated the production in enormous quantities that to finish asymmetric link arm.
The beneficial effects of the utility model: simple in structure, easy to use, cost of manufacture is cheap, and a clamping location, can repeat processing parts, save the time of centering in a large number, improved working (machining) efficiency, and improved the machining accuracy of part, simultaneously, less demanding to operator's technical ability.The spy is applicable in the large batch of production process.
