Abstract
The utility model discloses turning clamps in a kind of conical pipe, including standard chuck and casing, the outer surface of casing is the consistent straight face of straight claw with standard chuck, the inner surface of casing is axially extending with the consistent tapered surface of conical pipe interlude taper to be processed, the gap on radially inside and outside surface is formed on casing, and gap, along the both ends axially through casing, casing is held between multiple straight claws of standard card disk.Wherein, tapered surface and conical pipe interlude taper to be processed coincide, it can cover on conical pipe interlude to be processed, play the role of clamping position, gap on casing, for providing elastic expansion range, therefore, the utility model can save the new car development time, reduce claw cost of manufacture, and quickly mold changing.
Description
Technical field
The utility model relates to attachments of a bicycle processing technique field, it is specifically related to turnery processing folder in a kind of conical pipe
Tool.
Background technique
Chuck is the mechanical device for being used to clamp workpiece on lathe.Utilize the radial direction for the movable jaw being evenly arranged on chuck body
It is mobile, the machine tool accessories of Workpiece clamping and positioning.Chuck is generally by 3 part of chuck body, movable jaw and claw driving mechanism
Composition.There is through-hole in chuck body center, will pass through workpiece or bar；There is cylindrical or short taper profile structure at back, directly or by
Ring flange is connected with machine tool chief axis end.
Currently, aluminium alloy vehicle head tube when doing interior turning, needs to be clamped with chuck taper (abnormity or necking), because vehicle is first
Manage tapered, there is certain taper, the clamping face of the included movable jaw of standard chuck be it is straight, can not directly use, it is past
Toward that need to need to design and produce the special jaw with certain taper, result in the need for that most time is spent to go design, production, examination
With claw or special jaw is bought, thus the cost for increasing mould replacing time, making claw.
Summary of the invention
In order to solve the above-mentioned technical problem, it the utility model proposes turning clamp in a kind of conical pipe, can save
The new car development time reduces claw cost of manufacture, and quickly mold changing.
The technical solution of the utility model is achieved in that
Turning clamp in a kind of conical pipe, including standard chuck and casing, the outer surface of described sleeve pipe be with it is described
The consistent straight face of the straight claw of standard chuck, the inner surface of described sleeve pipe be axially extend among conical pipe to be processed
The section consistent tapered surface of taper, the gap on radially inside and outside surface is formed in described sleeve pipe, and the gap is along axial direction
The both ends of described sleeve pipe are penetrated through, described sleeve pipe is held between multiple straight claws of the standard chuck.
Further, the standard chuck includes chuck body and three straight claws moving radially, described sleeve pipe clamping
Between the described three straight claws, conical pipe interlude to be processed is sheathed in described sleeve pipe.
Further, described sleeve pipe is aluminium-alloy pipe, and the tapered surface of described sleeve pipe passes through CNC lathe inner wall turnery processing shape
At.
Further, the gap processes to be formed by hacksaw, and the gap width is 1mm-2mm.
The beneficial effects of the utility model are: the utility model provides turning clamp in a kind of conical pipe, closed with aluminium
Golden pipe forms casing according to conical pipe taper (gradient) production, can directly match with standard chuck, and production and structure are very
Simply, can alternate design buy special jaw, and then can save the new car development time, reduce claw cost of manufacture, and
Quickly mold changing.
Detailed description of the invention
Fig. 1 is the exploded view of turning clamp in the utility model conical pipe；
Fig. 2 is the assembling side elevation of turning clamp in the utility model conical pipe；
Fig. 3 is the assembled front view of turning clamp in the utility model conical pipe.
Specific embodiment
To keep the utility model more obvious and easy to understand, a specific embodiment of the invention is done in detail with reference to the accompanying drawing
Thin explanation.
As shown in Figure 1, Figure 2 and Figure 3, turning clamp in a kind of conical pipe, including standard chuck 1 and casing 2, it is described
The outer surface of casing is the consistent straight face 21 of straight claw 11 with the standard chuck, and the inner surface of described sleeve pipe is along axial direction
Extend with the consistent tapered surface 22 of 3 interlude taper of conical pipe to be processed, be formed in described sleeve pipe radially inside and outside
The gap 23 on surface, and the gap, along the both ends axially through described sleeve pipe, described sleeve pipe is held on the standard chuck
Between multiple straight claws.
In above structure, the inner surface of casing makes shape according to the taper (gradient) of conical pipe to be processed (such as vehicle head tube)
It is formed at (identical) tapered surface consistent with conical pipe interlude taper to be processed axially extended, then on casing along diameter
To the gap on inside and outside surface, a kind of simple claw of tubulose being adapted to conical pipe to be processed is formd, wherein tapered surface
It coincide with conical pipe interlude taper to be processed, can cover on conical pipe interlude to be processed, play the role of clamping position,
Gap on casing prevents conical pipe to be processed in interior turning process, holds tightly stuck for providing elastic expansion range.The letter
Easy claw can be matched directly with standard chuck, and be made and structure very simple, can alternate design buy special jaw,
And then the new car development time can be saved, reduce claw cost of manufacture, and quickly mold changing.
Preferably, referring to Fig. 1, the standard chuck includes chuck body 12 and three straight claws 11 moving radially, institute
It states casing to be held between the described three straight claws, conical pipe interlude to be processed is sheathed in described sleeve pipe.In this way, logical
Crossing three straight claw grip sleeves can be completed assembly, replaces straight claw relative to special jaw, greatly reduces mould replacing time,
In this way, can quickly be changed the mold when doing turning in various sizes of vehicle head tube.
Preferably, described sleeve pipe is aluminium-alloy pipe, and the tapered surface of described sleeve pipe passes through CNC lathe inner wall turnery processing shape
At.The gap processes to be formed by hacksaw, and the gap width is 1mm-2mm.In this way, it is only necessary to a section common 60-
100MM length diameter is greater than the aluminium-alloy pipe of the workpiece 10MM that need to process or so, CNC lathe inner wall turnery processing with need to process
Workpiece interlude taper it is consistent, aluminium-alloy pipe cuts to the seam of a 1-2MM with hacksaw again after complete, makes very simple
It is single, the development time of new car is greatly saved.
Above embodiments are that the preferred embodiment of the utility model is described in detail referring to attached drawing.The skill of this field
Art personnel are by carrying out modification or change on various forms, but the feelings of the essence without departing substantially from the utility model to above-described embodiment
Under condition, all fall within the scope of the present invention.
