Description
Technical field
The invention belongs to Machining Technology field, be specifically related to a kind of pipe rod workpieces auxiliary clamping mechanism.
Background technology
Turnery processing is a kind of manufacturing process that revolving body workpieces outer rim is processed, and it is simple that it has the course of processing, and easy to operate, good processing accuracy, automaticity advantages of higher, is manufacturing field processing mode the most basic, most important.
But in some field, turnery processing also encounters some and compares stubborn problem, such as draw ratio pipe/rod workpieces more than 10:1, due to when horizontal clamping, pipe/rod workpieces is inevitably subject to action of gravity and produces bending, therefore can cause that workpiece axiality declines, the problems such as course of processing vibration is unstable greatly.Consequently, it is possible to not only the crudy of workpiece is affected, even the lathe used by processing can be influenced by vibration effect and causes precise decreasing.As can be seen here, the processing pipe/rod workpieces more stable for how, prior art does not also provide good solution.
Summary of the invention
It is an object of the invention to overcome deficiency of the prior art, it is provided that a kind of pipe rod workpieces auxiliary clamping mechanism, it is possible to pipe/rod workpieces is carried out auxiliary positioning clamping, so that it is guaranteed that axiality, raising machining accuracy.
For solving prior art problem, the technical solution used in the present invention: a kind of pipe rod workpieces auxiliary clamping mechanism, including pedestal, at least two is coaxially disposed and is slidedly assemblied in the detent mechanism on pedestal, the connecting gear that at least two can lift, and respectively detent mechanism and connecting gear can be fixed on the retaining mechanism on pedestal；Connecting gear and detent mechanism are crisscross arranged.
Preferably, detent mechanism includes the door frame with a through hole, and is arranged on the screw slider mechanism on door frame；The lower half of through hole is provided with two supporting rollerns, and the first half of through hole is provided with screw slider mechanism；The slide block of screw slider mechanism is provided with pinching roller；Supporting rollern and the coplanar setting of action roller, and its axis is parallel with axis of workpiece；Workpiece can be clamped by pinching roller and supporting rollern in combined effect.
Preferably, connecting gear includes the bearing that can regulate height, and is arranged on the carrying roller on bearing；The roll surface of carrying roller has one along the circumferentially disposed anti-slip tank of roll surface.
Preferably, connecting gear also includes the slowspeed machine that is connected with carrying roller.
Preferably, retaining mechanism includes clamping screw, and the both sides of door frame are provided with positioning tab, and clamping screw is assemblied on lug.
Preferably, the leading screw top of screw slider mechanism is additionally provided with rotation dish.
Preferably, supporting rollern and pinching roller adopt carbon tool steel to make.
Preferably, the quantity of detent mechanism is three, and the quantity of connecting gear is two.
Preferably, pedestal be further arranged below universal wheel.
The invention have the benefit that this frock is capable of the auxiliary positioning clamping to pipe/rod workpieces, it is prevented that workpiece, because of the flexural deformation by gravity, improves axiality；Not only increase machining accuracy, prevent the vibration that high speed rotating produces.Additionally there is simple in construction, the advantage such as practical.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.Following example are only for clearly illustrating technical scheme, and can not limit the scope of the invention with this.
If Fig. 1 is to shown in 5, with a length for 5m, diameter is the drilling rod of 10cm is example, specifically describe the auxiliary clamping mechanism processing this drilling rod 10, it includes pedestal 1, three detent mechanisms being coaxially disposed and being slidedly assemblied on pedestal 1, two connecting gears, and respectively detent mechanism and connecting gear can be fixed on the retaining mechanism on pedestal 1.
Detent mechanism includes the door frame 2 with a through hole, and is arranged on leading screw 6 slide block 5 mechanism on door frame 2；The lower half of through hole is provided with two supporting rollerns 3, and the first half of through hole is provided with leading screw 6 slide block 5 mechanism.Leading screw 6 top of leading screw 6 slide block 5 mechanism is additionally provided with rotation dish 7, and the slide block 5 of leading screw 6 slide block 5 mechanism is provided with pinching roller 4.Supporting rollern 3 and the coplanar setting of action roller, and its axis is parallel with drilling rod 10 axis.Drilling rod 10 can be clamped by pinching roller 4 and supporting rollern 3 in combined effect, and supporting rollern 3 and pinching roller 4 adopt carbon tool steel to make.
Each connecting gear is arranged between adjacent two detent mechanisms, and it includes being arranged on pedestal and can regulate bearing 11 highly, is arranged on the carrying roller 12 on bearing and the slowspeed machine being connected with carrying roller.The roll surface of carrying roller has one along the circumferentially disposed anti-slip tank of roll surface, it is possible to make drilling rod be always positioned in anti-slip tank in transmission process thus preventing it from sliding to the axial side of carrying roller and affecting clamping.Owing to drilling rod is longer and has bigger quality, therefore realize auxiliary transmission effect when transmitting by slowspeed machine.
Retaining mechanism includes clamping screw 9, and the both sides of door frame 2 are provided with positioning tab 8, and clamping screw 9 is assemblied on lug 8.Pedestal 1 be further arranged below universal wheel, facilitate the movement of this frock.
The operation principle of the present invention and process
As shown in Figures 4 and 5, this frock is first moved so that it is be positioned at lathe tail and align with lathe spindle.Regulating the clamping screw of connecting gear, enable bearing to depart from pedestal, then inserted between the two by cushion block, finally tighten clamping screw and locked by connecting gear, now the transmission plane of carrying roller is higher than the top of supporting rollern；Drilling rod does not contact with supporting rollern when transmitting on carrying roller.Carrying roller serves support effect during this period, when clamping is passed to the chuck of lathe successively in one end of drilling rod from door frame 2, cushion block is taken away and makes bearing and carrying roller drop to below the height of supporting rollern, now drilling rod 10 afterbody is held thus preventing sagging by supporting rollern 3, regulates three detent mechanisms and makes its diverse location being reasonably distributed in drilling rod 10 with support drilling rod 10 better.When mechanism to be positioned moves to correct position, it is locked on pedestal 1 by clamping screw 9 and prevents it movable in the course of processing.Last rotation dish 7 of manually tightening, control slide block 5 declines so that pinching roller 4 and drilling rod 10 wall contacts realize the final fixing of drilling rod 10.
Due to the use of this frock, drilling rod 10 can remain level in turning process, and then improves machining accuracy and processing stability.
The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, under the premise without departing from the technology of the present invention principle; can also making some improvement and deformation, these improve and deformation also should be regarded as protection scope of the present invention.
