Description
Technical Field
The utility model relates to a boring machine inclined plane processing location frock belongs to inclined plane processing location technical field.
Background
The boring machine is a machine tool which mainly uses a boring cutter to bore holes on a workpiece, usually, the rotation of the boring cutter is main motion, the movement of the boring cutter or the workpiece is feeding motion, the machining precision and the surface quality of the boring machine are higher than those of a drilling machine, and the boring machine is main equipment for machining large box parts.
In the boring machine processing, the situation of processing holes on a plurality of inclined planes of the same workpiece can be met, and the traditional processing mode has the defects of low processing precision and low production efficiency due to the lack of freely-convertible positioning reference.
Disclosure of Invention
To the problem that above-mentioned prior art exists, the utility model provides a boring machine inclined plane processing location frock, this frock can provide the location benchmark for inclined plane spot facing work, and can realize improving machining precision and production efficiency to the quick transition of different inclined plane processing.
In order to achieve the purpose, the utility model provides a positioning tool for inclined plane processing of a boring machine, which comprises a tool bottom plate, wherein a positioning ring matched with a workpiece is fixedly connected on the tool bottom plate, the positioning ring is rotationally matched with the workpiece, and a plurality of pin shaft holes are formed on the tool bottom plate at the periphery of the positioning ring;
a threaded hole is formed in the tool bottom plate at the center of the positioning circular ring, a screw sequentially penetrates through the nut and the pressing plate from top to bottom to be matched with the threaded hole, a long circular hole is formed in the center of the pressing plate, the width of the long circular hole is smaller than the diameter of the nut, and two ends of the pressing plate in the length direction fall on a workpiece;
the workpiece is provided with a through hole matched with the pin shaft hole and is connected with the pin shaft hole through a pin shaft.
Furthermore, the height of the positioning ring is slightly less than that of the round hole of the workpiece to be machined at the position matched with the positioning ring.
Furthermore, the positioning circular ring is welded on the tool bottom plate.
The utility model discloses a set up location ring and compress tightly the system on the frock bottom plate, should fix a position the ring and cooperate with the circular port rotation that offers on the work piece, when rotating to the inclined plane that will process, drive the clamp plate through screwing up the screw rod and push down the work piece, until compressing tightly the work piece on the frock bottom plate, reuse the round pin axle to fix the other end of work piece on the frock bottom plate, accomplish the location of reference surface and can carry out the hole processing; after one inclined plane is finished, the pin shaft is pulled out, the screw rod is unscrewed, the workpiece is rotated to the other inclined plane, the positioning work before the previous operation is repeated, and the hole machining of the next inclined plane is carried out.

Fig. 1 is a structural view of the present invention.
In the figure: 1. the tool comprises a tool bottom plate, 2, a workpiece, 3, a positioning ring, 4, a pin shaft hole, 5, a screw, 6, a nut, 7, a pressing plate, 8, a long round hole, 9, a through hole, 10 and a pin shaft.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1, the positioning tool for inclined plane machining of the boring machine comprises a tool bottom plate 1, wherein a positioning circular ring 3 matched with a workpiece 2 is fixedly connected to the tool bottom plate 1, the positioning circular ring 3 is in rotating fit with the workpiece 2, and a plurality of pin shaft holes 4 are formed in the tool bottom plate 1 at the periphery of the positioning circular ring 3;
a threaded hole is further formed in the tool bottom plate 1 at the center of the positioning ring 3, the screw rod 5 sequentially penetrates through the nut 6 and the pressing plate 7 from top to bottom to be matched with the threaded hole, a long circular hole 8 is formed in the center of the pressing plate 7, the width of the long circular hole 8 is smaller than the diameter of the nut 6, and two ends of the pressing plate 7 in the length direction fall on the workpiece 2;
the workpiece 2 is provided with a through hole 9 matched with the pin shaft hole 4 and is connected with the pin shaft hole 4 through a pin shaft 10.
In order to ensure the compression stability of the pressure plate 7 to the workpiece 2, the height of the positioning ring 3 is slightly less than the height of the circular hole of the workpiece 2 matched with the positioning ring.
In order to ensure the connection stability of the positioning circular ring 3 and the tool bottom plate 1, the positioning circular ring 3 is welded on the tool bottom plate 1.
Sleeving a circular hole formed in the bottom surface of a workpiece 2 on a positioning ring 3, rotating an inclined plane on the workpiece 2 to a machining reference surface by taking the positioning ring 3 as a rotating shaft, driving a pressing plate 7 to press the workpiece downwards by screwing a screw rod 5, pressing the workpiece 2 on a tool bottom plate 1, fixing the other end of the workpiece 2 on the tool bottom plate 1 by using a pin shaft 10, and positioning the reference surface to machine the hole; after one inclined plane is finished, the pin shaft 10 is pulled out, the screw rod 5 is unscrewed, the workpiece 2 is rotated to another inclined plane, the positioning work before the previous operation is repeated, and the hole machining of the next inclined plane is carried out.
