Abstract
The utility model relates to a tool for preventing a large caliber thin-wall casing threaded surface from chattermarks. The tool comprises two semicircle iron rings, an upper support bar, a lower support bar, a steel cylinder, a steel bar and screws. The upper support bar is arranged on the inner wall of an upper semicircle iron ring, the lower support bar is arranged on the inner wall of a lower semicircle iron ring, the steel cylinder is arranged in the middle of the upper support bar, the steel bar is arranged in the middle of the lower support bar, and the screws are screwed on the steel bar. The upper support bar, the lower support bar, the steel cylinder and the steel bar form an I-shaped structure, and the I-shaped structure is positioned on the inner wall of a right cylindrical iron ring which consists of the upper semicircle iron ring and the lower semicircle iron ring. With the tool, the chattermarks which are produced on the threaded surface when a large caliber thin-wall casing is machined are eliminated. The tool is simple in structure and convenient to operate and has a good use effect. The tool can be used as an auxiliary tool for machining the threads of the large caliber thin-wall casing.
Description
Technical field
The instrument that the utility model relates to is a kind of at the bottom of the Yin Chesi cutter causes screw thread tooth top, tooth with casing resonant during for the large-caliber thin-walled sleeve pipe of prevention processing, line is quivered in the flank generation.
Background technology
In processing during large-caliber thin-walled partially trapezoidal sleeve pipe and since car silk cutter and sleeve pipe produce resonance make tooth top, tooth at the bottom of, the flank generation line that quivers.Car silk cutter and casing resonant can shorten the service time of car silk cutter greatly, and then affect the lathe life-span, because resonance makes thread surface produce the line that quivers, affect thread quality simultaneously.Research finds, why when the large-caliber thin-walled sleeve pipe of processing screw thread produce the line that quivers be since the intrinsic frequency of lathe is consistent with the thin wall casing frequency and working angles in backlash characteristics cause.
Summary of the invention
The purpose of this utility model provides a kind of large-caliber thin-walled casing threads surface line proactive tool that quivers, the line that quivers that thread surface produces when eliminating the large-caliber thin-walled sleeve pipe of processing.
Technical solution of the present utility model is: the line proactive tool quivers on a kind of large-caliber thin-walled casing threads surface, comprise two semicircle iron rings (1), upper support bar (2), lower support bar (4), steel cylinder (3), rod iron (5) and screw (6), first circular iron ring (1) inwall is provided with upper support bar (2), upper support bar (2) middle part is provided with steel cylinder (3), lower semi-circular iron ring (1) inwall is provided with lower support bar (4), lower support bar (4) middle part is provided with rod iron (5), rod iron (5) outer surface is provided with screw thread, the screw thread of rod iron (5) is provided with screw (6), rod iron (5) is a positive cylindrical shape iron ring after inserting in the steel cylinder (3) first circular iron ring (1) and lower semi-circular iron ring (1) being connected as one, upper support bar (2) and lower support bar (4) form an I-shaped structure with steel cylinder (3) and rod iron (5), and I-shaped structure is positioned at the circular iron ring inwall of first circular iron ring (1) and lower semi-circular iron ring (1) composition.
Described first circular iron ring (1) and lower semi-circular iron ring (1) outer wall are provided with rubber.
First circular iron ring (1) and lower semi-circular iron ring (1) are a positive cylindrical shape iron ring after merging, positive cylindrical shape iron ring external diameter is slightly less than large-caliber thin-walled casing inner diameter to be processed, and positive cylindrical shape iron ring length equates with reach with large-caliber thin-walled casing threads equal in length length to be processed.
The utility model has designed a kind of quiver instrument of line of large-caliber thin-walled casing threads of eliminating, and is conceived to avoid the resonance region of cutter and sleeve pipe and reduces cutting gap.Application shows that this instrument can eliminate large-caliber thin-walled casing threads fully and add the line that quivers that produces man-hour, is worth of widely use.
The utlity model has following advantage:
The line that quivers that thread surface produced when 1) the utility model had been realized eliminating the large-caliber thin-walled sleeve pipe of processing.
2) the utility model is simple in structure, and is easy to operate, and result of use is good.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Structure of the present utility model as shown in Figure 1.A kind of large-caliber thin-walled casing threads surface line proactive tool that quivers comprises two semicircle iron rings 1, upper support bar 2, lower support bar 4, steel cylinder 3, rod iron 5 and screws 6, and first circular iron ring 1 and lower semi-circular iron ring 1 outer wall scribble one deck rubber.Be a positive cylindrical shape iron ring after first circular iron ring 1 and lower semi-circular iron ring 1 merge, positive cylindrical shape iron ring external diameter is slightly less than large-caliber thin-walled casing inner diameter to be processed, and length equates with reach.The inwall place of first circular iron ring 1 is welded with upper support bar 2, upper support bar 2 centers are welded with steel cylinder 3, lower semi-circular iron ring 1 inwall place is welded with lower support bar 4, and upper support bar 2 and lower support bar 4 are welded on semicircle iron ring 1 inwall perpendicular to semicircle iron ring 1 axis.Lower support bar 4 centers are welded with rod iron 5, rod iron 5 outer surface cars have screw thread, the screw thread of rod iron 5 is provided with screw 6, rod iron 5 is a positive cylindrical shape iron ring after inserting in the steel cylinders 3 first circular iron ring 1 and lower semi-circular iron ring 1 being connected as one, upper support bar 2 and lower support bar 4 form an I-shaped structure with steel cylinder 3 and rod iron 5, and I-shaped structure is positioned at the circular iron ring inwall of first circular iron ring 1 and lower semi-circular iron ring 1 composition.
This large-caliber thin-walled casing threads quivers, and to eliminate the implementation step of instrument as follows for line:
(1) screw 6 is screwed on the rod iron 5, with steel cylinder 3 and rod iron 5
Shape as shown in Figure 1.
(2) large-caliber thin-walled casing threads is quivered line elimination instrument is put into inside pipe casing to be processed, and flushes with pipe end.
(3) set screw 6, and semicircle iron ring is contacted with certain force with internal surface of sleeve pipe.
The utility model operation principle is as follows:
(1) large-caliber thin-walled casing threads quivers and has changed the intrinsic frequency of sleeve pipe after line is eliminated instrument and the screw thread inwall is contacted with certain force, and cutter and sleeve pipe are not in the resonance region.
(2) semicircle iron ring outer wall scribbles one deck rubber, and semicircle iron ring contacts with certain force with internal surface of sleeve pipe by rubber, makes internal surface of sleeve pipe stressed evenly, and then makes the sleeve pipe pipe end cutting gap that become positive circular, less.
