A kind of frock clamp for processing support eyes waist hole
Technical field
The utility model relates to a kind of frock clamp for processing support eyes waist hole.
Background technology
Support in the Digit Control Machine Tool, see Fig. 1, shown in Figure 2, comprise body 1 ', described body 1 ' be provided with two eyes waist holes 2 ' and baseline positioning hole 3 ', its quantity required is a lot, and the main feature of this part is two eyes waist holes 2 ' be hole to be processed, on irregular appearance profile face, two eyes waist holes 2 ' with baseline positioning hole 3 ' be the state of being parallel to each other, with end face higher perpendicularity requirement is arranged, and the high dimension precision requirement is arranged.It is incorrect that clamping is located, and its deflection is increased, and dimensional accuracy does not reach requirement, make on drilling machine difficulty of processing bigger, clamping is incorrect, can produce distortion, does not reach the specification requirement after the processing, and, working (machining) efficiency is very low, and process-cycle and cost are strengthened, and requires also higher to processor's industrial grade, the input of enterprise is increased, very uneconomical.
Summary of the invention
The purpose of this utility model is to provide a kind of can locate, clamp convenience, not yielding to support fast and accurately fast, and can significantly save a large amount of centering positioning times, shorten process time significantly, improved the frock clamp that is used for processing support eyes waist hole of operating efficiency.
For reaching the goal of the invention the technical solution adopted in the utility model be:
A kind of frock clamp for processing support eyes waist hole, it is characterized in that: comprise a flat base, described base is provided with the first either side of the small of the back hole according to two eyes waist holes of support and the angle between the baseline positioning hole and pitch-row setting, the second either side of the small of the back hole, the benchmark pin-and-hole, be connected with a reference pins on the described benchmark pin-and-hole, be connected with in the outside of the first either side of the small of the back hole and benchmark pin-and-hole line on the described base with reference pins and be used alignment pin with the support location, also be connected with in the outside of the first either side of the small of the back hole and benchmark pin-and-hole line on the described base support is pressed on pressing plate on the base.
Further, described pressing plate is connected with base by screw.
The utility model comes locating support by reference pins and alignment pin, compresses support with pressing plate, just can be with boring the eyes waist hole of expanding cutter processing support.
The course of work of the present utility model is as follows:
1, according to the position of setting, correctly reference pins, alignment pin, pressing plate are installed on the base.
2, put into the T type groove of lathe with T type nut, frock clamp for processing support eyes waist hole 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 of processing support eyes waist hole described in the utility model, make the frock clamp for processing support eyes waist hole described in the utility model reach vertical, horizontal perpendicularity requirement.
3, after the frock clamp for processing support eyes waist hole described in the utility model installs, baseline positioning hole in the support is inserted in the reference pins, and swinging mounting makes a true edge of support bump alignment pin, to determine the accurate Working position of support, compress support with pressing plate again.
4, with brill expansion cutter milling being carried out in the eyes waist hole of support gets final product.To be processed finishing unclamped pressing plate, takes out support, and whole process is just finished.
5, repeat above-mentioned steps 3 and step 4, next part is operated the production in enormous quantities that to finish support.
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.
