Description

Clamping tool suitable for turning appearance of rain erosion cap
Technical Field
The utility model relates to a machining technical field, in particular to clamping frock suitable for rain erosion cap appearance car processing.
Background
The rain-proof cap that loses of radome is polytetrafluoroethylene material usually, and structural style is that one side is the sharp awl unanimous with the cover body appearance, and the another side is the inner chamber that can laminate cover body appearance, is the cylinder section of connecting cover body point portion round hole in the middle of the inner chamber, and the cylinder section has partial region in the inner chamber, and cylinder section size is longer and less with the interval between the inner chamber wall.
The prior art mills the cylinder section and inner chamber simultaneously on the numerical control milling machine, or adopts the turning form alone with the processing of cylinder section, nevertheless because the processing space is little, the cylinder section is long, because of cutter draw ratio is big in the traditional cutter course of working, cutter rigidity not enough produces the cutter relieving phenomenon, causes the processing of cylinder section excircle diameter unqualified.
SUMMERY OF THE UTILITY MODEL
The utility model aims at: the utility model provides a clamping frock suitable for rain erosion cap appearance car processing, aims at solving the damage problem that the rain erosion cap is insecure in the location of clamping in-process and causes because of the clamping.
The technical scheme of the utility model:
the clamping tool suitable for turning the appearance of the rain erosion cap comprises the rain erosion cap, a threaded shaft and a clamping sleeve, wherein a threaded hole is formed in the cylindrical section of the rain erosion cap, the threaded shaft is arranged in the threaded hole, the clamping sleeve is sleeved outside the cylindrical section of the rain erosion cap, the top surface and the end surface of the clamping sleeve are attached to the inner wall surface of an umbrella-shaped inner hole of the rain erosion cap, and the inner wall surface of the clamping sleeve is attached to the outer wall surface of the cylindrical section of the rain erosion cap.
The clamping sleeve is provided with a strip-shaped groove which runs through the surface of the clamping sleeve.
The inner wall of the threaded hole is provided with an internal thread, and the outer wall of the threaded shaft is provided with an external thread matched with the internal thread.
The length of the threaded shaft is longer than that of the threaded hole.
The strip-shaped groove is parallel to the central axis of the clamping sleeve.
The width of the strip-shaped groove is 0.5-1 mm.
The utility model has the advantages that: the clamping tool suitable for turning the appearance of the rain erosion cap effectively solves the problems that the rain erosion cap is difficult to clamp and is easy to damage in the appearance machining process, is simple in structure and convenient to use, and obtains good quality benefits and economic benefits.
Drawings
FIG. 1 is a schematic structural view of the present invention;
the labels in the figure are: 1-rain erosion cap, 2-jacket and 3-threaded shaft.
Detailed Description
It is right to combine the figure below the utility model makes further introduction, be applicable to the clamping frock of rain erosion cap appearance car processing, including rain erosion cap 1, threaded shaft 3 and clamping cover 2, 1 cylinder section of rain erosion cap in seted up a screw hole, threaded shaft 3 set up threaded hole inside to the rigidity of reinforcing 1 cylinder section of rain erosion cap, clamping cover 2 cover outside at 1 cylinder section of rain erosion cap, clamping cover 2 top surface and terminal surface all laminate mutually with 1 umbrella shape hole internal face of rain erosion cap, the internal face of clamping cover 2 laminates mutually with 1 cylinder section outer wall face of rain erosion cap.
The clamping sleeve 2 is provided with a strip-shaped groove which runs through the surface of the clamping sleeve, the strip-shaped groove is parallel to the central axis of the clamping sleeve 2, and the width of the strip-shaped groove is 0.5-1 mm.
The inner wall of the threaded hole is provided with an internal thread, the outer wall of the threaded shaft 3 is provided with an external thread matched with the internal thread, and the length of the threaded shaft 3 is longer than that of the threaded hole.
During clamping, the threaded shaft 3 is firstly installed in a threaded hole of a cylindrical section of the rain etching cap 1 to enhance the rigidity of the cylindrical section of the rain etching cap 1, then the clamping sleeve 2 is fixed on the cylindrical section of the rain etching cap 1, the top surface and the end surface of the clamping sleeve are attached to the wall surface of an umbrella-shaped inner hole of the rain etching cap 1, and finally the tool and the rain etching cap 1 are clamped on a three-jaw chuck of a lathe together.
The utility model discloses the effectual clamping difficulty of having solved in the rain erosion cap in appearance course of working, the problem of easy damage, simple structure, convenient to use has gained fine quality benefit and economic benefits.
