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 electric spindle structure of work bench.
Background technology
Work on hand platform electro spindle, its cooperation sucker carries out the sticking to workpiece, because gas circuit uniform on sucker is communicated with mutually, workbench electro spindle is made only to need a tracheae can complete and being communicated with of the gas circuit of sucker, and then remove the workpiece of sticking fixed dimension, because this workbench electro spindle can only correspond to the sucker of sticking fixed dimension workpiece, make the workpiece of each size need corresponding different workbench electro spindle, make the poor universality of workbench electro spindle, add the input cost of equipment.
Summary of the invention
For the problems referred to above, the invention provides electric spindle structure of work bench, after it makes workbench electro spindle fit on sucker, can the workpiece of sticking different size, make the versatility of workbench electro spindle good, reduce the input cost of equipment.
Electric spindle structure of work bench, its technical scheme is such: it comprises protecgulum, main shaft bonnet, housing, rotating shaft, motor, revolve change device, the central area of described rotating shaft is provided with gas circuit, described gas circuit is communicated with the vacuum valve of its afterbody, described housing, the cavity that both main shaft bonnets are formed is built with described rotating shaft, motor, revolve change device, the output of described rotating shaft is fastenedly connected described protecgulum, described rotating shaft is fastenedly connected the rotor of described motor, described revolving becomes one end that device is set in described rotating shaft, it is characterized in that: the central area of described rotating shaft is provided with at least two gas circuits, described in every bar, the afterbody of gas circuit connects described vacuum valve respectively by swivel joint, described in the corresponding every bar of described protecgulum, the position of gas circuit has through hole.
It is further characterized in that: the rear end of described rotating shaft is supported on by angular contact bearing in the internal cavities of described main shaft bonnet, and described rotating shaft front end is supported in described housing by bidirectional angular contact thrust ball bearing;
Bearing friction top press-fits the bearing in described bidirectional angular contact thrust ball bearing, and described protecgulum is fastenedly connected described bearing friction top, and described bearing friction top is fastenedly connected the output of described rotating shaft.
In said structure of the present invention, center due to described rotating shaft is provided with at least two gas circuits, described in every bar, the afterbody of gas circuit connects described vacuum valve respectively by swivel joint, described in the corresponding every bar of described protecgulum, the position of gas circuit has through hole, the through hole of protecgulum is connected respectively the gas circuit of correspondingly-sized workpiece on sucker, make every bar gas circuit can the workpiece of corresponding sticking specific dimensions, after it makes workbench electro spindle fit on sucker, can the workpiece of sticking different size, make the versatility of workbench electro spindle good, reduce the input cost of equipment.
