Abstract
The utility model discloses a drilling device for the inner chamber of a machine tool spindle, comprising a machine tool spindle which is installed in a machine tool body in a rotating manner; the front end of the spindle is fixedly installed with a chuck; a drilling pipe is matched in the inner chamber of the spindle in a sliding manner; the front end of the drilling pipe is fixedly installed with a reversed-blade drill bit; the rear side of the spindle is provided with a cylinder which is fixedly installed on the machine tool body; a piston rod of the cylinder is fixedly connected with the rear end of the drilling pipe; the piston rod of the cylinder is fixedly connected with a limiting electric switch button; and a limiting check block is connected on the machine tool body and positioned right in front of the limiting electric switch button. By adopting the drilling device, the inner chamber of the machine tool spindle is provided with the reversed-blade drill bit; the simultaneousconduction of the drilling of a center hole and the processing of a workpiece is realized; the coaxiality requirement of products is ensured; the quality of the products is improved; and the scrap rate is reduced.
Description
Technical field
The utility model belongs to machine tools, specifically is a kind of machine tool chief axis inner chamber drilling equipment.
Background technology
At present, the leading product routinely of producing of each lathe producer, as numerically controlled lathes such as 32 series, 36 series, 40 and 50 series, though the convenience of processed complex curved surface (as tapering, circular arc etc.) is provided for applying unit, but at working shaft-like, or when needing the part of drill centers and so on, also must manually utilize lathe tailstock to process.Both wasted the time, manpower, electric energy, can not well guarantee the axiality requirement of centre bore and processing excircles again, the frock for next procedure requires to have increased difficulty simultaneously.
The utility model content
The purpose of this utility model provides a kind of machine tool chief axis inner chamber drilling equipment, inner chamber at machine tool chief axis is equipped with anti-cutting drill head, has realized that the processing of drill centers and workpiece is carried out simultaneously, has guaranteed the axiality requirement of product, improve the quality of product, reduced percent defective.
The technical solution of the utility model is as follows:
Machine tool chief axis inner chamber drilling equipment, include and rotate the hollow main shaft that is installed in the body, the front end of main shaft is installed with chuck, it is characterized in that: be sliding combined with drilling rod in the described main shaft inner chamber, the front end of drilling rod is installed with anti-cutting drill head and can reaches the perforate outside of chuck central authorities, the main shaft rear side has the cylinder that is fixedly installed on the body, the piston rod of cylinder is fixedlyed connected with the rear end of drilling rod, be fixedly connected with spacing electric switch button on the piston rod of cylinder, on the described bed body dead ahead that positive stop is positioned at spacing electric switch button be installed.
Described machine tool chief axis inner chamber drilling equipment is characterized in that: be combined with fairlead in the described chuck, be sliding combined with anti-cutting drill head in the fairlead.
Described machine tool chief axis inner chamber drilling equipment is characterized in that: be circumscribed with connecting rod on the described bed body, be installed with connecting plate between the connecting rod, described cylinder is fixedly mounted on the connecting plate.
Anti-cutting drill head is installed in the inner chamber of machine tool chief axis of the present utility model, and drill bit drives by cylinder piston rod, has realized that the processing of drill centers and workpiece is carried out simultaneously, has guaranteed the axiality requirement of product, has improved the quality of product, has reduced percent defective.
Be fixedly connected with spacing electric switch button on the piston rod of cylinder of the present utility model, be connected with the dead ahead that positive stop is positioned at spacing electric switch button on the bed body, when drill bit is drilled into set depth, spacing electric switch button contacts with positive stop, spacing electric switch button is pressed, and drill bit quits work.
The numeral that the utility model adopts and pneumatic and connect control mode, it is compared with external hydraulic means following advantage:
1, using electricity wisely: the hydraulic means separate unit need dispose a cover Hydraulic Station, and pneumatic means only needs be connected with other sources of the gas and gets final product, and has saved electricity consumption greatly.
2, the low and environmental protection of use cost: hydraulic means needs hydraulic oil, and cost height, waste oil produce and pollute.And
3, pneumatic means just utilizes compressed air, and can recycle, and cost is low, and energy savings is environmental protection more.
4, manufacturing cost: the manufacturing cost of a pneumatic means only is 1/4th of a hydraulic means.
5, because of this device be according to compressed air as motive force, flexible feeding is better, the impact that produces in the time of can reducing the firm smear metal of cutter, thereby protected cutter, improved the service life of cutter
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is spacing electric switch button of the present utility model and positive stop location diagram.
The specific embodiment
Referring to accompanying drawing, machine tool chief axis inner chamber drilling equipment, include and rotate the machine tool chief axis 2 that is installed in the body 1, the front end of main shaft 2 is installed with chuck 3, be combined with fairlead 6 in the chuck 3, fairlead 6 is a copper sheathing, be sliding combined with drilling rod 4 in main shaft 2 inner chambers, the front end of drilling rod 4 is installed with anti-cutting drill head 5, anti-cutting drill head 5 is slidingly matched with fairlead 6, main shaft 2 rear sides have the cylinder 7 that is fixedly installed on the body 1, are circumscribed with connecting rod 8 on the bed body 1, are installed with connecting plate 9 between the connecting rod 8, cylinder 7 is fixedly mounted on the connecting plate 9, the piston rod of cylinder 7 is fixedlyed connected with the rear end of drilling rod 4, is fixedly connected with spacing electric switch button 10 on the piston rod of cylinder 7, is connected with the dead ahead that positive stop 11 is positioned at spacing electric switch button 10 on the bed body 1.
