Abstract
The utility model provides a high-precision gantry-type drilling machine, which mainly solves the problem that the precision of a processed hole is relatively low due to the fact that a drill bit vibrates when the existing gantry drilling machine is used for drilling. The high-precision gantry-type drilling machine is characterized in that a gantry (1) consists of a stand column (101), a casing pipe (102), an upper cross beam (103) and a lower cross beam (104), wherein the stand column (101) is positioned in the casing pipe (102) and forms a clearance with the inner wall of the casing pipe (102), a motor (4) is fixedly arranged on a sliding seat (12) which is arranged on the upper cross beam (103), the sliding seat (12) is connected with a spindle box (2) through a connecting rod (9), the two ends of the connecting rod (9) are provided with a buffer jacket (10) respectively, and torque between an output shaft of the motor (4) and an input shaft of the spindle box (2) is transferred by a buffer coupling (11). The high-precision gantry-type drilling machine has the beneficial effects that the influence of motor vibration on the processing precision of workpieces is eliminated, and a drilling tool shaft and the drill bit are in stable operation without vibrating, so that the drilling precision is improved.
Description
Technical field
The utility model relates to a kind of lathe, is specifically related to a kind of high accuracy planer-type drilling machine.
Background technology
Drilling machine is the lathe that utilizes drill bit machining hole on workpiece, and drill bit, as cutter, carries out axial feed in the time of bit, complete the boring to workpiece.Drilling machine is divided into upright drill, radial drilling machine, bench drill, planer drilling machine etc. by structure, planer drilling machine wherein mainly is comprised of portal frame, crossbeam, main spindle box, feed box and motor, motor is fixed on the main spindle box top, feed box is connected with main spindle box, the drilling tool axle is installed in feed box, the lower end of main shaft is connected with drill chuck, the drill chuck drill bit that can be installed.Main spindle box is arranged on also can be along the crossbeam transverse shifting on crossbeam, and the below of portal frame is provided with workbench.In use, workpiece is fixed on workbench, needs the position of boring on the drill bit alignment pieces, and the drilling tool axle rotates and moves down, and realizes boring.There is following technological deficiency in this planer drilling machine: because motor is connected on main spindle box, and main spindle box is connected with feed box, the vibration that motor produces when operation is delivered to feed box by main spindle box, and then the drilling tool axle is vibrated together in company with feed box, thereby drill bit also can produce vibration when creeping into, will make like this Aperture deviation that gets out larger, the processed hole machining accuracy on workpiece is lower.
The utility model content
Cause the lower deficiency of processed hole precision in order to overcome existing planer drilling machine drill bit vibration-generating when holing, the utility model provides a kind of high accuracy planer-type drilling machine, this high accuracy planer-type drilling machine has been eliminated the impact of motor oscillating on the processed hole machining accuracy on workpiece, drilling tool axle and drill bit operate steadily, do not vibrate, and have improved borehole accuracy.
The technical solution of the utility model is: a kind of high accuracy planer-type drilling machine comprises portal frame, main spindle box, feed box and motor, feed box is connected with main spindle box, the drilling tool axle is installed in feed box, the lower end of drilling tool axle is connected with drill chuck, the drill chuck drill bit that can be installed, the below of portal frame is provided with workbench, portal frame is by column, sleeve pipe, entablature and sill form, column also and between internal surface of sleeve pipe has space in sleeve pipe, entablature is fixed on column, sill is fixed on sleeve pipe, entablature parallels with sill, motor is fixed on slide, slide is arranged on also can be along the entablature transverse shifting on entablature, main spindle box and feed box are arranged on also can be along the sill transverse shifting on sill, between slide and main spindle box, by connecting rod, be connected, the two ends of connecting rod are equipped with cushion collar, pass through the buffering coupling transmitting torque between the output shaft of motor and the power shaft of main spindle box.
Described column lower end and sleeve pipe lower end all fix with the ironware be embedded in basis.
The utlity model has following beneficial effect: owing to taking such scheme, when motor produces vibration, the vibration of the output shaft of motor is absorbed when buffering coupling, and vibration wave can not be delivered on the power shaft of main spindle box; The vibration of the base of motor is delivered on slide and is cushioned cover and absorbs, vibration wave can not pass on main spindle box by connecting rod yet, therefore, when boring, the vibration of motor can not be delivered on main spindle box and make its vibration-generating, eliminated the impact of motor oscillating on the processed hole machining accuracy on workpiece, drilling tool axle and drill bit operate steadily, do not vibrate, and have improved borehole accuracy.
