Description

Internal support clamp for machining square through part

Technical Field

The utility model belongs to the machining field, concretely relates to internal stay anchor clamps for processing four directions lead to part.

Background

Most square-through type parts face the problem of repeated positioning and clamping during cutting and machining, the repeated positioning precision is inaccurate, and accumulated errors exist; and the labor hour is wasted, and the labor intensity of the operators is correspondingly increased. In order to ensure the precise size of the die-casting part and improve the production efficiency, a set of excellent tool clamp is very important.

Patent document No. 201510923012.6 discloses a lathe fixture for a polygonal part, which comprises a connecting base and a tightening nut cover, wherein one end of the connecting base can be connected with a lathe chuck, the other end of the connecting base is provided with an opening and an external thread, and the end surface of the opening is provided with a polygonal clamping groove matched with the shape of the polygonal part; the tightening nut cover is of a cup-shaped structure, can be in threaded connection with the connecting base so as to press the polygonal part, and is provided with a through hole on the bottom surface. The outer surface of the connecting base is provided with a limiting boss.

The inventor finds that the technical scheme has the defects of inaccurate positioning and high labor intensity of operators.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide an internal stay anchor clamps for processing square tube part makes things convenient for square tube part four sides cutting process, reduces repeated clamping error, improves the machining precision.

The utility model discloses technical scheme as follows: an inner support clamp for processing a square through part 2 is characterized by comprising an inner support device, wherein the inner support device comprises a numerical control dividing plate 1, a first inner support block 3, a second inner support block 4, a base 5, a connecting rod mechanism 6 and a fastening assembly;

the base 5 is connected with the numerical control dividing disc 1 through the fastening assembly, the first inner support block 3 is fixed on the base 5 through an accommodating groove, and an inclined plane and a dovetail groove are formed in the first inner support block; be equipped with in the second on the vaulting block with inclined plane and dovetail matched with recess and sand grip, vaulting block 4 in the second about with inclined plane, left right direction with dovetail matched with recess and sand grip slide in the first on the vaulting block 3, vaulting block 4 passes through in the second link mechanism 6 drives, through vaulting block 4 is in relative motion about on the first interior vaulting block 3 comes the clamp to lead to the part in four directions.

Further, a clamping device is also included, which comprises a handle 18, a coupling pin 9, a second coupling pin 10, a third coupling pin 11 and a positioning pin; the link mechanism 6 comprises a first link part 7 and a second link part 8; the coupling pin 9, the second coupling pin 10 and the third coupling pin 11 are mounted on the link mechanism. The positioning pin is used for locking the position of the connecting rod mechanism, so that the clamping device is not loosened during processing.

Preferably, the fastening assembly includes a T-shaped square nut 12 and a screw.

Further, a cover plate 16 and a screw 17 are included.

The working principle of the utility model is that when clamping, the handle 18 rotates counterclockwise to drive the link mechanism 6 to rotate, and drive the second connecting rod part 8 to rotate by taking the connecting pin 9 as the center, when the connecting pin 9 is positioned between the second connecting pin 10 and the third connecting pin 11, three points are in a line, namely the clamped dead point; at the moment, the square through part needing to be processed is in an inner supporting and clamping state.

When the connecting pin is loosened, the positioning pin is taken down, the handle 18 rotates clockwise to drive the connecting rod mechanism 6 to rotate, the second connecting rod part 8 rotates by taking the connecting pin 9 as the center, and when the connecting pin 9 is positioned at one side of the second connecting pin 10 and the third connecting pin 11, three points are in a line, namely a loosened dead point; at the moment, the square through part needing to be machined is in an inner support loose state.

The beneficial effects of the utility model reside in that: the utility model discloses to the clamping location of the part of square tube type with press from both sides the anchor clamps of fixed and research and development, simple structure, convenient operation fixes a position accurately, safe firm.
