Description
Technical field
Machining equipment technical field is the utility model is related to, specially a kind of cut end side machining apparatus.
Background technology
Connecting shaft is as connection or assembles every accessory, and generally using light, the good alloy pipe of resistance to torsion is made.
In the processing technology of existing connection axial end, connecting shaft is clamped on lathe by generally use scroll chuck carries out top add
Work, the chuck body 1 of the scroll chuck now used at present is built with three bevel pinions 3, as depicted in figs. 1 and 2, these three conelets
Gear 3 all engages with bevel gear wheel 2, and the flat thread at the back side of bevel gear wheel 2 engages with three claw back side screw threads；Processing
When, first need four square hole transfers of any one bevel pinion 3 on the chuck handle insertion face of cylinder to move, then bevel gear wheel 2 is just
Concomitant rotation, subsequently, the flat thread at its back side just drive radial direction of three claws along chuck body 1 into groove while done centripetal
Or centrifugal motion, it is complicated to clamp the workpiece of different-diameter, and the time length of whole clamping process is completed, also just lead
Cause the processing efficiency of rotary shaft low.
Utility model content
The utility model is intended to provide a kind of clipping operation simple cut end side machining apparatus.
The utility model provides base case：Cut end side machining apparatus, including lathe, it is provided with lathe for clamping
The clamping device of connecting shaft, wherein, the side of lathe is provided with riser, and clamping device is arranged on riser, and clamping device includes
The grip block and chuck of wedge shape, one end of grip block are hinged on riser, and the one end of grip block away from riser, which can close up, surrounds one
The individual holding holes for the axle that is clamped and connected；The outer surface of grip block is provided with screw thread, and chuck is provided with mounting hole, and chuck passes through mounting hole
It is threadedly coupled with grip block, grip block can close up after chuck rotates.
The operation principle of base case：Lathe is for carrying out end face processing to connecting shaft；, it is necessary to first will even before processing
Spindle is fixed on the clamping device on riser；
The mounting hole set on the chuck of clamping device is for connection to grip block, and grip block is for connecting shaft
Gripped, after the outer surface of grip block is threaded, rotating chuck, chuck will be along the appearance of grip block wedge shape
The threads turn in face, and during chuck rotates, chuck moves radially along grip block, during movement, respectively
Individual grip block moves closer to close up, so as to be clamped to the connecting shaft being first placed on grip block；And rotate backward chuck,
Each grip block then scatters, it is possible to removes connecting shaft.
The beneficial effect of base case is：Compared with existing scroll chuck, turned in 1. the utility model by chuck
Dynamic to be directly realized by the closing up so as to be clamped to connecting shaft of grip block, simple in construction, the operating time is short, improves connecting shaft
Processing efficiency；2. compared with claw, grip block is bigger with the contact area of connecting shaft, that is, connecting shaft is pressed from both sides by grip block
Pressure when holding reduces, so as to avoid connecting shaft because the pressure of clamping is excessive to cause damaged surfaces.
Preferred scheme one：Based on scheme it is preferred, grip block be used to the being clamped and connected end face of axle is provided with cushion pad.
Beneficial effect：, generally all can be as far as possible when being clamped to connecting shaft in order to ensure clamping of the grip block to connecting shaft
Clamping connecting shaft, like this, active force between grip block and connecting shaft is also just larger, if directly by connecting shaft with folder
Hold block to be contacted, it is possible to connecting shaft surface occur and situation about damaging occur, therefore, in grip block with setting between connecting shaft
After putting cushion pad, row buffering is entered by cushion pad, can thus reduce the pressure that connecting shaft is subject to, so as to avoid connecting shaft
Surface is damaged.
Preferred scheme two：Preferably one it is preferred, cushion pad be with telescopic annulus.Beneficial effect：Choosing
Select telescopic annulus and reduce what each point of connecting shaft was subject to as the cushion pad can of a closing as cushion pad, annulus
Pressure, the surface that just completely avoid connecting shaft are damaged.
Preferred scheme three：Preferably two it is preferred, cushion pad uses silica gel.Beneficial effect：In view of to not
When being processed with the connecting shaft of size, it is necessary to which cushion pad can reach different sizes, and silica gel is as normal
A kind of rubber, its elongation at break（Elongation at break refers to when rubbery sample is broken, its elongated portion and raw footage
The ratio between）More than 200%, meet the installation requirement of various sizes of connecting shaft enough.
Preferred scheme four：Preferably three it is preferred, cushion pad is connected to grip block and is used to be clamped and connected the one of axle
Face.Beneficial effect：If being processed again in view of first cushion pad is enclosed in connecting shaft, compared to directly cushion pad is arranged on
On grip block, during processing, first have to need to strut cushion pad and then on connecting shaft is enclosed on, and cushion pad be set on gripper pad,
Cushion pad is enclosed in connecting shaft by can while fixed connection shaft, and operation is more simple.
Preferred scheme five：Based on scheme it is preferred, chuck is provided with handle.Beneficial effect：Handle is set to chuck
Afterwards, can be by handle rotating chuck, handle provides stress point, simple to operate.
