Description
Technical Field
The utility model belongs to the technical field of the frock design, especially, relate to a general tight device in top.
Background
With the continuous development of aviation manufacturing industry, the requirements on manufacturing efficiency and economy are higher and higher. During tool design, various process operations are often required to be carried out on the workpiece in a tight-pushing and fixing mode so as to reduce structural deformation and meet drawing requirements.
However, the existing tightening device cannot realize the functions of quick tightening and loosening, is inconvenient to operate and has no universality.
SUMMERY OF THE UTILITY MODEL
The utility model provides a general tight device in top solves the function that current tight device in top can't realize pushing up tightly fast, loosen, and the operation is inconvenient, and does not possess the problem of commonality.
The utility model provides a general tight device in top, include: the device comprises a base 1, an adjusting screw 2, a compression screw 3 and a compression plug 4;
the base 1 is fixed on a processing machine tool, a first threaded hole and a second threaded hole are formed in the base 1, the first threaded hole penetrates through the base 1, and the second threaded hole is perpendicularly intersected with the first threaded hole;
the top end of the adjusting screw rod 2 is hemispherical, the adjusting screw rod 2 penetrates through the first threaded hole, and a workpiece is tightly jacked through the hemispherical top end;
the compression screw rod 3 penetrates through the second threaded hole, and the top end of the compression screw rod 3 props against the threaded rod part of the adjusting screw rod 2 through the compression plug 4.
Optionally, the base 1 is a cube, two sides of the cube are provided with fixing bosses, and both the two fixing bosses are provided with U-shaped grooves;
the base 1 is fixed on a processing machine tool through bolts penetrating through the U-shaped grooves.
Optionally, the base 1 is a cube, fixing bosses are arranged on two sides of the cube, and positioning holes are formed in the two fixing bosses;
the base 1 is fixed on a processing machine tool through bolts penetrating through the positioning holes.

Detailed Description
The following explains the general tightening device provided by the present invention with reference to the drawings.
Referring to fig. 1-3, the utility model provides a general tight device in top includes: the base 1, adjusting screw 2, compression screw 3, compress tightly end cap 4.
Wherein, base 1 has U type recess, fixes on machine tool equipment through U type recess.
The adjusting screw rod 2 is transversely screwed on the base 1, and the spherical end tightly pushes or loosens the workpiece. The compression screw 3 is vertically screwed on the base 1, and acting force is applied to the adjusting screw 2 through the compression plug 4. The end parts of the adjusting screw rod 2 and the pressing screw rod 3 are both provided with a rotating handle, so that the operation is convenient.
The material of the pressing plug 4 is brass, and lead brass HBP59-1 can be selected as an example.
Use the utility model provides a during general tight device in top, at first fix base 1 on machine tool equipment, loosen compression screw 3 through rotatory handle, make adjusting screw 2's the tight work piece in spherical end top through rotatory handle, then will compress tightly 3 rotatory downstream of screw, exert pressure to adjusting screw 2 through compressing tightly end cap 4, guarantee 2 lateral stability of adjusting screw, reliably push up tightly the work piece. After the working procedure is completed, the pressing screw 3 and the adjusting screw 2 are respectively loosened, and then the workpiece can be loosened.
Adopt the utility model discloses when pushing up tightly the work piece, easy operation is convenient, uses reliably. The part is tightly propped in a point contact mode, so that the defects that the existing device is not strong in universality and cannot tightly prop part of the part are overcome.
