Abstract
The utility model discloses cylindrical workpiece fixing tool, including base, it is fixed on the cylindrical shape fixture on base, Circle-Array shows multiple bar v notch vs for axially opening up on the top tube wall of the fixture, the fixture inwall of the breach hypomere is provided with internal thread, support member is connected with the fixture, support member includes the cylindrical connecting portion of bottom and the truncated cone-shaped expansion mouth on top, the outer wall of the connecting portion is provided with the external screw thread being connected with the screw-internal thread fit of the fixture, the lower surface of the expansion mouth overlaps with the upper surface of connecting portion, the pipe thickness sum of expansion mouth upper surface diameter and fixture is equal to the internal diameter of workpiece.Rotatable support moves down expansion mouth makes it prop up the workpiece inner wall being enclosed within fixture so as to strut the bar v notch v of fixture, and fixed form is linear contact lay, and robust will not cause to damage, using efficient and convenient to workpiece body.
Description
Technical field
The utility model is related to machining field, and in particular to a kind of cylindrical workpiece fixing tool.
Background technology
The parts such as columnar short metal pipe, pipe joint are very big in the usage amount of field of hardware, in cylindrical workpiece
Outer wall on groove milling, drilling blind hole is the common technology in machining field, is currently used for fixing the frock of cylindrical workpiece more and using
General triangle chuck carries out clamping, and the pressure that the radial direction of cylindrical workpiece can bear is limited, and chuck is made in clamping
It is small with area, piece-holder section deformation is easily caused in the case that chucking power is too big, or even occur crackle on tube wall, and card
Dish structure is relative complex, and cost is also of a relatively high.
The content of the invention
The utility model overcomes existing defect to provide a kind of cylindrical workpiece fixing tool, and simple structure is easy to use fast
It is prompt.
The utility model is achieved through the following technical solutions：
Cylindrical workpiece fixing tool, including base, are fixed on the cylindrical shape fixture on base, the fixture it is upper
Circle-Array shows multiple bar v notch vs for axially opening up on portion's tube wall, and the fixture inwall of the breach hypomere is provided with interior spiral shell
Line, is connected with support member in the fixture, support member includes the cylindrical connecting portion of bottom and the truncated cone-shaped expansion mouth on top,
The outer wall of the connecting portion is provided with the external screw thread being connected with the screw-internal thread fit of the fixture, the lower surface of the expansion mouth with
The upper surface of connecting portion overlaps, and the pipe thickness sum of expansion mouth upper surface diameter and fixture is equal to the internal diameter of workpiece.
The further improvement project of the utility model is that the upper surface middle part of expansion mouth is provided with a curved handle, workpiece
Slid to the base downwards from the upper end of curved handle.
The further improvement project of the utility model is, the one of of length no more than fixture height of the bar v notch v
Half.
The further improvement project of the utility model is that the bar v notch v is at least six.
The utility model has advantages below compared with prior art：
The utility model simple structure, rotatable support moves down expansion mouth makes it so as to strut the bar v notch v of fixture
The workpiece inner wall being enclosed within fixture is propped up, fixed form is linear contact lay, and robust will not cause to damage to workpiece body,
Using efficient and convenient.
Brief description of the drawings
Fig. 1 is the utility model overlooking the structure diagram.
Specific embodiment
Cylindrical workpiece fixing tool as shown in Figure 1, including base 1, are fixed on the cylindrical shape fixture 2 on base 1,
Circle-Array shows multiple bar v notch vs 3 for axially opening up on the top tube wall of fixture 2, on the inwall of fixture 2 of the hypomere of breach 3
It is provided with and support member 4 is connected with internal thread, fixture 2, support member 4 includes the cylindrical connecting portion 5 of bottom and the round platform on top
Shape expansion mouth 6, the outer wall of connecting portion 5 is provided with the external screw thread being connected with the screw-internal thread fit of the fixture 2, under expansion mouth 6
End face overlaps with the upper surface of connecting portion 5, and the pipe thickness sum of the upper surface diameter of expansion mouth 6 and fixture 2 is equal to workpiece 7
Internal diameter.
In the present embodiment, the upper surface middle part of expansion mouth 6 is provided with a curved handle 8, convenient when using to grip rotation,
Workpiece 7 is slid to base 1 downwards from the upper end of curved handle 8, without support member and fixture are separated, directly by workpiece 7
Can be slipped on base through curved handle, it is easy to use.The half of the height of of length no more than fixture 2 of bar v notch v 3.
Bar v notch v 3 is at least six, respectively whole circumference, uniform force, fixed reliable.
