Abstract
The utility model discloses a tooling fixture body for machining two holes of a rocker arm. The tooling fixture body comprises a base, wherein a first tool withdrawal hole, a second tool withdrawal hole and a reference pin hole which are arranged according to angles and hole pitches among three holes of the rocker arm are formed in the base; a reference pin for positioning a reference hole of the rocker arm is arranged in the reference pin hole; a positioning pin which is matched with the reference pin to position the rocker arm is connected to the outer side of a connecting line of the first tool withdrawal hole and the second tool withdrawal hole on the base; and a pressing plate for fixing the rocker arm is also connected to the outer side of the second tool withdrawal hole on the base. The tooling fixture body disclosed by the utility model has the advantages of simple structure, convenience in use and low manufacturing cost; according to the tooling fixture body, one-time clamping and positioning is realized, parts can be repeatedly machined and the aligning time is greatly saved, so that the machining efficiency is increased; and in addition, the machining precision of the parts is improved. Meanwhile, the tooling fixture body has low requirement on skills of operators and is especially suitable for large-batch production processes.
Description
Technical field
The utility model relates to a kind of frock clamp body for processing rocking arm two holes.
Background technology
Rocking arm, as Fig. 1, shown in Figure 2, comprise body 1 ' and be arranged on body 1 ' on first hole 2 ', second hole 3 ', the 3rd hole 4 ', it is applied in the Digit Control Machine Tool, being in great demand of this part, and the main feature of this part is the hole after having drilled and reamed, first hole 2 ' be, as datum hole, and second hole 3 ', the 3rd hole 4 ' be two holes that will process, and this two Kong Yaoyu, first hole is parallel to each other, and two holes are vertical with end face, the entity height in three holes is unequal, this part volume is less, complex-shaped, make on drilling machine difficulty of processing bigger, clamping is incorrect, can produce distortion, do not reach the specification requirement after the processing, and working (machining) efficiency is very low, process-cycle and cost are strengthened, and the industrial grade requirement to the processor is also higher, and the input of enterprise is increased, and is 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 the rocking 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 processing rocking arm two holes 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 processing rocking arm two holes, it is characterized in that: comprise a base, described base is provided with the first withdrawing hole, the second withdrawing hole, the benchmark pin-and-hole that arranges according to the angle between rocking arm three holes and pitch-row, reference pins for location rocking arm datum hole is installed in the described benchmark pin-and-hole, be connected with for the alignment pin that cooperates with reference pins the rocking arm location in the line in the first withdrawing hole and the second withdrawing hole outside on the described base, also be connected with the pressing plate that rocking arm is fixed on the described base in the outside in the second withdrawing hole.
Further, described base is a flat base.
Further, described pressing plate is connected on the base by screw.
The utility model comes the tram in centering rocking arm two holes by an alignment pin and a reference pins, and limits the free degree that is placed in the rocking arm on the base simultaneously, by pressing plate rocking arm is compressed.
The course of work of the present utility model is as follows:
1, according to the position of setting, correctly reference pins, pressing plate, alignment pin are installed on the base.
2, put into the T type groove of lathe with T type nut, frock clamp body for processing rocking arm two holes 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 rocking arm two holes described in the utility model, make the frock clamp body for processing rocking arm two holes described in the utility model reach vertical, horizontal perpendicularity requirement.
3, after the frock clamp body for processing rocking arm two holes described in the utility model installs, as long as rocking arm is placed between reference pins and the alignment pin, is pressed on the end face of rocking arm with pressing plate again and gets final product.
4, with process tool to rocking arm bore, reaming gets final product.To be processed finishing unclamped pressing plate, takes out rocking 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 rocking 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.
