Abstract
The invention provides an electric spindle structure of a work bench. After an electric spindle of the work bench is assembled with a suction cup, different sizes of work-pieces can be held, the generality of the electric spindle of the work bench is good, and the invested cost of equipment is reduced. The electric spindle structure of the work bench comprises a front cover, a spindle rear cover, a shell, a rotating shaft, a motor and a rotary converter, wherein a gas circuit is arranged in a center area of the rotating shaft; the gas circuit is communicated with a vacuum valve at the tail part; the rotating shaft, the motor and the rotary converter are arranged inside a cavity formed by the shell and the spindle rear cover; the front cover is fixedly connected with output end of the rotating shaft; the rotating shaft is fixedly connected with a rotor of the motor, and the rotary converter is sleeved at one end of the rotating shaft. The electric spindle structure of the work bench is characterized in that at least two gas circuits are arranged in the centre area of the rotating shaft; the tail part of each gas circuit is respectively connected with the vacuum valve through a rotary joint, and through holes are respectively formed on the part of the front cover corresponding to each gas circuit.
Description
Technical field
The present invention relates to the main axle structure technical field of lathe, be specially workbench electricity main axle structure.
Background technology
Work on hand platform electricity main shaft, it cooperates sucker to carry out the sticking to workpiece, because the gas circuit that is uniformly distributed with on the sucker is communicated with mutually; Make workbench electricity main shaft only need a tracheae can accomplish and being communicated with of the gas circuit of sucker; And then remove the workpiece of sticking fixed dimension, because this workbench electricity main shaft can only make the workpiece of each size need corresponding different working platform electricity main shaft corresponding to the sucker of sticking fixed dimension workpiece; Make that the versatility of workbench electricity main shaft is poor, increased the input cost of equipment.
Summary of the invention
To the problems referred to above, the invention provides workbench electricity main axle structure, it makes on the workbench electricity spindle mounted behind the sucker, workpiece that can the sticking different size makes that the versatility of workbench electricity main shaft is good, has reduced the input cost of equipment.
Workbench electricity main axle structure; Its technical scheme is such: it comprises protecgulum, main shaft bonnet, housing, rotating shaft, motor, revolves the change device; The central area of said rotating shaft is provided with gas circuit, and said gas circuit is communicated with the vacuum valve of its afterbody, in said housing, both formed cavitys of main shaft bonnet said rotating shaft, motor is housed, revolves the change device; The output of said rotating shaft is fastenedly connected said protecgulum; Said rotating shaft is fastenedly connected the rotor of said motor, and said revolving becomes the end that device is set in said rotating shaft, and it is characterized in that: the central area of said rotating shaft is provided with at least two gas circuits; The afterbody of every said gas circuit connects said vacuum valve through swivel joint respectively, and the position of corresponding every the said gas circuit of said protecgulum has through hole.
It is further characterized in that: the rear end of said rotating shaft is supported on through angular contact bearing in the internal cavities of said main shaft bonnet, and said rotating shaft front end is supported in the said housing through two-way angular contact thrust ball bearing;
The bearing friction top press-fits in the bearing of said two-way angular contact thrust ball bearing, and said protecgulum is fastenedly connected said bearing friction top, and said bearing friction top is fastenedly connected the output of said rotating shaft.
In the said structure of the present invention; Because the center of said rotating shaft is provided with at least two gas circuits, the afterbody of every said gas circuit connects said vacuum valve through swivel joint respectively, and the position of corresponding every the said gas circuit of said protecgulum has through hole; The corresponding respectively gas circuit that connects correspondingly-sized workpiece on the sucker of the through hole of protecgulum; Make the workpiece that every gas circuit can corresponding sticking specific dimensions, it makes on the workbench electricity spindle mounted behind the sucker, workpiece that can the sticking different size; Make that the versatility of workbench electricity main shaft is good, reduced the input cost of equipment.
Description of drawings
Fig. 1 is the structural representation of front view of the present invention.
