Abstract
The utility model discloses a pull rod type copying device used for turning an arc-shaped part in a deep blind hole with large caliber, and relates to a pull rod type copying device. The pull rod type copying device solves the problem that the processing precision is low and the processing efficiency is low due to the manual cutting in the existing method of manually cutting an inner arc of the deep blind hole with the large caliber interruptedly. A bottom plate is fixedly installed below a pressing plate, one end of a connecting rod is fixedly connected with the pressing plate, the other end of the connecting rod is connected with one end of a pull rod in a rotating manner by a positioning pin, the other end of the pull rod is connected with a triangular plate in a rotating manner by another positioning pin, and the triangular plate is fixed on a tool rest. The pull rod type copying device is used for helping turning the arc-shaped part in the deep blind hole with the large caliber.
Description
Technical field
The utility model relates to a kind of rod-pulling type copying apparatus, is specifically related to a kind of rod-pulling type copying apparatus that is used for the dark blind hole arc of turning heavy caliber position.
Background technology
The dark blind hole class of the heavy caliber part that is used for the weapons field is a lot, wherein great majority are the dark blind hole class of the heavy caliber part at bullet position, at present, the dark blind hole arc of the manual interrupted cut heavy caliber positions of adopting more, upper slitter and the bigger vibration of withdrawing generation repeatedly when manually cutting, can only rely on feel when cutter cuts in deep hole, can not directly observe, cause deep hole arc place occur quivering line, machining accuracy is low and the working (machining) efficiency of manual cutting is low.
The utility model content
There is the inefficient problem of the low and manual machining of machining accuracy in the utility model for the method that solves the dark blind hole arc of existing manual interrupted cut heavy caliber position, and then a kind of rod-pulling type copying apparatus that is used for the dark blind hole arc of turning heavy caliber position is provided.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: the rod-pulling type copying apparatus that is used for the dark blind hole arc of turning heavy caliber position of the present utility model is made of triangular plate, two alignment pins, pull bar, connecting rod, pressing plate and base plates, described base plate is packed in the below of pressing plate, one end and the pressing plate of described connecting rod are affixed, the other end of described connecting rod is rotationally connected by an end of an alignment pin and pull bar, the other end of described pull bar is rotationally connected by another alignment pin and triangular plate, and described triangular plate is fixed on the knife rest.
The beneficial effects of the utility model are:
Rod-pulling type copying apparatus of the present utility model adopts the diameter of the dark blind hole arc of pull bar control heavy caliber, the length of pull bar is the radius length of the dark blind hole arc of heavy caliber, diameter by the dark blind hole arc of pull bar control heavy caliber, improve the machining accuracy at the dark blind hole arc of heavy caliber position greatly, satisfied the processing request of the dark blind hole class of field of machining heavy caliber part arc; The utility model does not need repeatedly upper slitter and withdrawing, has improved working (machining) efficiency greatly.
Description of drawings
Fig. 1 is the vertical view of rod-pulling type copying apparatus of the present utility model.
The specific embodiment
The specific embodiment one: as shown in Figure 1, the rod-pulling type copying apparatus that is used for the dark blind hole arc of turning heavy caliber position of present embodiment is made of triangular plate 1, two alignment pins 2, pull bar 3, connecting rod 5, pressing plate 6 and base plates 8, described base plate 8 is packed in the below of pressing plate 6, one end and the pressing plate 6 of described connecting rod 5 are affixed, the other end of described connecting rod 5 is rotationally connected by the end of an alignment pin 2 with pull bar 3, the other end of described pull bar 3 is rotationally connected with triangular plate 1 by another alignment pin 2, and described triangular plate 1 is fixed on the knife rest 9.
The specific embodiment two: as shown in Figure 1, the shape of the described pressing plate 6 of present embodiment is L-shaped.So design is convenient to be connected with connecting rod 5.Other composition and annexation are identical with the specific embodiment one.
Operation principle:
Be installed in rod-pulling type copying apparatus of the present utility model on two guide rails 10 of lathe by pressing plate 6 and base plate 8, and be free to slide along the length direction of guide rail 10, supporting plate leading screw in knife rest 9 and the lathe is broken away from, then the cutter on the knife rest 9 11 is aimed at dark blind hole straight line of heavy caliber and arc connecting part, when knife rest 9 during along the axis direction self-acting feed of lathe, triangular plate 1 on the drive knife rest 9 moves along the axis direction of lathe, be subjected to the tractive force effect of set square 1, the pull bar 3 that is rotationally connected with triangular plate 1 will be that rotate at the center with the alignment pin on the connecting rod 52, thereby control knife rest 9 is done the circular motion of same track, finish the processing at the dark blind hole arc of heavy caliber position, the length of pull bar 3 is the radius length of the dark blind hole arc of heavy caliber, as process the part of these type of different circular arcs, the length that only needs to change pull bar 3 gets final product.
