Abstract
The utility model relates to a device for drilling an inclined hole in the side wall of a spiral tooth of a large nut, which mainly consists of a main shaft connecting rod, a bracket and a magnetic drill arranged on the bracket, and is characterized in that the rear end of the main shaft connecting rod is provided with a mallet handle; the bracket is formed by a vertical plate fixedly connected below the front end of the main shaft connecting rod, a horizontal supporting plate with the rear end fixedly connected below the vertical plate, and an inclined supporting plate fixedly connected at the front end of the horizontal supporting plate; a through hole is arranged in the position of the inclined supporting plate close to the horizontal supporting plate, and a drill bushing is embedded in the through hole; and the head of the magnetic drill penetrates through the drill bushing and is adsorbed on the inclined supporting plate. The device has the advantages of being capable of accurately positioning drilling positions, not only being convenient to operate and anti-skidding during drilling, but also being capable of greatly improving the working efficiency, and being especially applicable to the machining of an oil supply small hole on a screw box of a heavy mill.
Description
Technical field
The utility model belongs to machine tool accessories, particularly relates to a kind of device that is used for rat holing on the thread sidewall of large-scale nut.
Background technology
Screw box is the vitals of milling train screwdown gear, milling train when work screw box and housing screw between to depress transmission by high speed rotating, owing to will carry huge roll-force, thereby usually adopt and have good wearability and higher intensity and the copper alloy of toughness and make, in addition in order to reduce the friction of housing screw and screw box contact-making surface, improve service life, to on this large-scale nut, lubricating system be set, this lubricating system is made up of several axial fuel feeding main apertures on the wall of screw box and the fuel feeding aperture that communicates with the fuel feeding main aperture that is arranged between each screw thread of screw box, this fuel feeding aperture is arranged on the spiral load surface of the root of thread and thread usually, fuel feeding aperture on the spiral load surface of thread be with the fuel feeding main aperture angled inclined hole, at present normal employing is manually held boring bar tool and is entered the method for holing in the screw box and process, its shortcoming is not only to locate inaccuracy, and when beginning to bore this inclined hole since drill bit easily skid, the boring difficulty is very big, causes operating efficiency very low.
Summary of the invention
The utility model provides a kind of location accurate, non-slip when holing for solving the technical problem that exists in the known technology, can increase substantially the device that is used for rat holing on the thread sidewall of large-scale nut of operating efficiency.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of device that is used for rat holing on the thread sidewall of large-scale nut, mainly by the main shaft connecting rod, carriage, and the magnetic drill press that is contained on the carriage is formed, it is characterized in that: the rear end of described main shaft connecting rod is provided with the vertebra handle, described carriage is by the riser that is fixed in below the main shaft connecting rod front end, the rear end is fixed in the horizontal supporting plate below the riser, and the oblique supporting plate that is fixed in horizontal supporting plate front end constitutes, close horizontal supporting plate place on oblique supporting plate has through hole, be installed with drill bushing in the through hole, the drill bit of described magnetic drill press pass drill bushing be adsorbed on oblique supporting plate above.
Advantage and the good effect that the utlity model has are: can be installed on the main shaft of boring machine by vertebra handle the utility model of main shaft connecting rod rear end, utilize the frock and the operating means of boring machine that the bore position of the fuel feeding aperture on the thread spiral load surface of large-scale nut is accurately located again, just can hole fast by the hand control magnetic drill press, not only easy to operate, and owing to be installed with drill bushing on the oblique supporting plate, prevented rocking of drill bit, make boring non-slip, thereby can increase substantially operating efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the I portion enlarged drawing of Fig. 1.
Label among the figure is respectively: the 1-large-scale nut; 2-fuel feeding main aperture; The 3-magnetic drill press; The oblique supporting plate of 4-; 5-main shaft connecting rod; The 6-riser; The horizontal supporting plate of 7-; The 8-drill bushing; 9-fuel feeding aperture.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2,1 is depicted as large-scale nut among the figure, and it is as the screw box of large-sized rolling mills, and 2 is the fuel feeding main aperture, and the utility model is the device that is used for rat holing on the thread sidewall of large-scale nut, promptly bores the device of fuel feeding aperture 9.The utility model is mainly by main shaft connecting rod 5, by riser 6, the carriage that horizontal supporting plate 7 and oblique supporting plate 4 constitute, and the magnetic drill press 3 that is contained on the oblique supporting plate of carriage is formed, for being connected with machine tool chief axis, the rear end of main shaft connecting rod is provided with the vertebra handle, the riser of carriage be welded on main shaft connecting rod front end below, the rear end of horizontal supporting plate is weldingly fixed on below the riser, the front end of the oblique supporting plate certain angle that is inclined upwardly is weldingly fixed on the front end of horizontal supporting plate, close horizontal supporting plate place on the oblique supporting plate of carriage has through hole, be installed with the drill bushing 8 that prevents that drill bit from rocking in the through hole, the lower end of drill bushing stretches out in horizontal supporting plate, magnetic drill press adopts commercially available by motor, magnetic support, gear-box, control circuit, and the magnetic drill press that constitutes such as drill bit, its drill bit pass drill bushing be adsorbed on oblique supporting plate above, drill bit adopts the extended type drill bit.
The utility model in use, can be by the vertebra handle of main shaft connecting rod rear end, it is installed on the main shaft of boring machine, utilize the frock and the operating means of boring machine successively the utility model accurately to be located with respect to the position of the fuel feeding aperture of desire brill again, the hand control magnetic drill press just can have been finished the bore operation of fuel feeding aperture fast again.
