Description
Technical field
The utility model relates to a kind of main shaft of vertical drilling machine with round column, belongs to upright drill technical field.
Background technology
Upright drill, as the one of drilling machine, is also more common Metal Cutting Machine Tool, is widely used, and the feature that precision is high is suitable for batch machining, is usually used in the hole of machine-building and the medium and small workpiece of repair factory process.Existing upright drill all installs pull bar in main shaft, to hold knife quick change chuck, makes cutter have good security performance.But existing pulling assembly is all be suspended on object in main shaft by arranging a turret head or nut in pull bar upper end to realize pull bar, although this kind of frame mode is simple, but when quick chuck is arranged on pull bar, also need with fixture, pull bar to be fixed, there is fixing inconvenient problem, simultaneously when main shaft works, pull bar likely there will be rotation, and this also can cause adverse effect to the machining accuracy of drilling machine.
Summary of the invention
The technical problems to be solved in the utility model: the main axle structure providing a kind of upright drill, effectively can fix pull bar, and to solve the installation inconvenience that prior art occurs, and pull bar rotates the problem of the machining accuracy difference caused.
Technical solutions of the utility model:
A main axle structure for upright drill, comprises main shaft, main shaft mounting bracket assembly, cutter pulling assembly and quick chuck, and main shaft installation component comprises sleeve, the bearing cap that is positioned at the floor clip of upper cartridge and round nut, is positioned at lower cartridge; Main shaft is bearing on sleeve by fore bearing group and rear bearing group; Cutter pulling assembly comprises pull bar, and pull bar is arranged in the main shaft of hollow, and be provided with screw thread in pull bar bottom, pull bar is threaded with quick chuck, and described pull bar top is provided with the tapered gland in bottom, is provided with projection at this taper position of gland; Described main shaft upper end open is the bellmouth matched with gland lower taper, in this bellmouth, be provided with the groove corresponding with projection.
The top of described gland is turret head, has both been beneficial to the fixing of pull bar, also facilitates and the dismounting of pull bar is taken out.
Described projection is 3, and be evenly arranged in the taper position of gland, described groove is 3, is evenly arranged in main shaft bellmouth, and this kind of structure has effectively taken into account the balance of fixed effect and manufacturing cost.
The beneficial effects of the utility model:
The utility model is by becoming the gland of band taper by pull bar tip designs, main shaft upper end open is designed to the taper hole matched with gland taper position, this kind of structure can realize the effectively fastening of pull bar in use; Simultaneously projection is set in gland, corresponding groove is set in spindle taper hole, the effective location of gland can be realized when fastening, decrease in prior art according to, change cutter time also need this step of steady brace, save operation labour.Compared with prior art, the utility model structure is simple, and fastening security is reliable, effectively can solve the installation inconvenience occurred in prior art, and pull bar rotates the problem of the machining accuracy difference caused.
accompanying drawing illustrates:
Fig. 1 is the utility model main axle structure schematic diagram;
Fig. 2 is Tiebar structure schematic diagram.
detailed description of the invention:
As depicted in figs. 1 and 2, the main axle structure of the utility model upright drill comprises main shaft 1, main shaft mounting bracket assembly, cutter pulling assembly and quick chuck 9, and main shaft installation component comprises sleeve 6, the bearing cap 8 that is positioned at the floor clip 4 on sleeve 6 top and round nut 3, is positioned at sleeve 6 bottom; Main shaft 1 is bearing on sleeve 6 by fore bearing group 5 and rear bearing group 7; Cutter pulling assembly comprises pull bar 2, pull bar 2 is arranged in the main shaft 1 of hollow, screw thread is provided with in pull bar 2 bottom, pull bar 2 adopts with quick chuck 9 and is threaded, pull bar 2 top is made into the tapered gland in bottom 10, be provided with projection 11 at this taper position of gland 10, the top of gland 10 is made into turret head; Main shaft 1 upper end open is the bellmouth matched with gland 10 lower taper, in this bellmouth, be provided with the groove corresponding with projection 11.
Specifically in the utility model, projection 11 is 3, and around the taper position being evenly arranged in gland 10, the groove on corresponding main shaft 1 in taper hole is also 3, and this kind of structure can take into account the balance of pull bar 2 fixed effect and manufacturing cost effectively.
