Abstract
Can the die sleeve of automatic centering, comprise fixing facing, attachment screw, trip bolt, movable facing and lock-screw; Described movable facing is connected with described fixing facing by four described attachment screws; The required free gap regulated is reserved: described movable facing is by countersunk head trip bolt locking between the screw hole of wherein said attachment screw and described fixing facing.The utility model utilizes fixing facing and movable facing can the mutual changing of the relative positions within the specific limits, realizes the automatic centering of threading die mantle fiber process.Not only effectively can solve the problems such as the crooked or rotten tooth of screw thread, and easy to operate, and working (machining) efficiency is high, can ensure the axiality of screw thread.Machining accuracy is easy to ensure, is very suitable for the processing of externally threaded batch mantle fiber.
Description
[technical field]
The utility model belongs to Machining Technology field, be specifically related to a kind of can the die sleeve of automatic centering.
[background technology]
Existing externally threaded processing method mainly contains machining and rolling and processing two class, and wherein machining on workpiece, processes external screw thread with forming tool or grinding tool, mainly comprises Che Xiao ﹑ Xi Xiao ﹑ mantle fiber and grinding etc.
In hot-water heating industry, usually adopt turning or mantle fiber to process external screw thread at copper alloy surface, wherein turning generally needs to carry out several times, and efficiency is lower.Mantle fiber on bar (or materials in the tube) workpiece, directly cuts out external screw thread with screw die on drilling machine or lathe.Adopt screw die to carry out mantle fiber and add man-hour, first will process bar (or materials in the tube) and chamfering according to mantle fiber required size; Then mantle fiber is carried out with screw die.For ensureing mantle fiber precision, screw die end face must be entirely on the center with the axes normal of bar (or materials in the tube).Although mantle fiber working (machining) efficiency is high, entirely on the center owing to being difficult to, especially for long external screw thread, very easily occur the problems such as the crooked or rotten tooth of screw thread, machining accuracy is difficult to be guaranteed.
[summary of the invention]
Technical problem to be solved in the utility model be to provide a kind of can the die sleeve of automatic centering, not only working (machining) efficiency is high, and machining accuracy is easy to control.
The utility model is achieved in that
Can the die sleeve of automatic centering, comprise fixing facing, attachment screw, trip bolt, movable facing and lock-screw; Described movable facing is connected with described fixing facing by four described attachment screws; The required free gap regulated is reserved between the screw hole of wherein said attachment screw and described fixing facing; Described movable facing is by countersunk head trip bolt locking.
The utility model has the advantage of: the utility model provide a kind of can the die sleeve of automatic centering, utilize fixing facing and movable facing can the mutual changing of the relative positions within the specific limits, realize the automatic centering of threading die mantle fiber process.Not only effectively can solve the problems such as the crooked or rotten tooth of screw thread, and easy to operate, and working (machining) efficiency is high, can ensure the axiality of screw thread.Machining accuracy is easy to ensure, is very suitable for the processing of externally threaded batch mantle fiber.
[accompanying drawing explanation]
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the utility model structural representation.
[detailed description of the invention]
As shown in Figure 1, a kind of can the die sleeve of automatic centering, comprise fixing facing 1, attachment screw 2, trip bolt 3, movable facing 4 and lock-screw 6.Movable facing 4 is connected with fixing facing 1 by four attachment screws 2, and fixing facing 1 gives movable facing 4 by four attachment screw 2 transmitting torques.The required free gap regulated is reserved between the screw hole of wherein attachment screw 2 and fixing facing 1.In addition, for preventing attachment screw 2 from occurring to loosen, with countersunk head trip bolt 3 locking.
Fixing facing 1 is fastened on drilling machine, and the screw die 5 of required specification is arranged on the end of movable facing 4 and locks with lock-screw 6.Drill press spindle drives fixing facing 1 to rotate, and fixing facing 1 is rotated by attachment screw 2 drive activity facing 4 again and carries out mantle fiber processing.When screw die 5 contacts workpiece, if the two exists little deviation, when failing entirely on the center, screw die 5 lead sword guiding under, to utilize between attachment screw 2 and fixing facing 1 screw hole reserved gap automatically to adjust existing deviation, realize automatic centering.Actual production practice shows, adopt this can the die sleeve threading of automatic centering, not only effectively can solve the problems such as the crooked or rotten tooth of screw thread, and it is easy to operate, working (machining) efficiency is high, and machining accuracy is easy to ensure, is very suitable for the processing of externally threaded batch mantle fiber.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field, to its suitable change done or modification, all should be considered as not departing from patent category of the present utility model.
