Abstract
The invention relates to a short spindle structure. The short spindle structure comprises a workbench, a gland, a gear, an angular contact ball bearing, a deep groove ball bearing, a short spindle and a base. The short spindle is arranged on the base and fixed through second bolts. The angular contact ball bearing is installed in an inner ring of the gear, the deep groove ball bearing is installed on the base, the gear and the angular contact ball bearing are installed on the short spindle, the deep groove ball bearing is used for supporting the short spindle, the gear rotates through the angular contact ball bearing and the deep groove ball bearing, and the gland is fixed to the head of the short spindle and used for fixing the angular contact ball bearing. The workbench is arranged on the gear, the workbench and the gear are connected and fixed through first bolts, and the gear drives the workbench to move. The short spindle structure is simple, ingenious and reasonable in structure, the load capacity of the short spindle is increased, the safety coefficient is improved, and the short spindle structure is stable and reliable.
Description
Technical field
The present invention relates to a kind of main axle structure, specifically a kind of short main axle structure, is specially adapted to vertical lathe, belongs to the annex of vertical lathe.
Background technology
Vertical car is mainly used in processing that diameter is large, length is short is large-scale, heavy workpiece and be difficult for the workpiece of clamping on horizontal lathe, in the satisfied situation of tactical diameter, too heavy workpiece is difficult for clamping at sleeping carriage, due to dead weight, machining accuracy is had to impact, adopt vertical car to address the above problem.
In prior art, the load capacity of main shaft is larger, therefore the improvement of main shaft is seemed to particularly important, is also instant.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, a kind of short main axle structure is provided, this is simple in structure, ingenious, reasonable, and it can realize short base bearing loading capacity increase, and safety coefficient improves.
According to technical scheme provided by the invention: a kind of short main axle structure comprises workbench, gland, gear, angular contact ball bearing, deep groove ball bearing, short main shaft and base; Described short main shaft is arranged on base, with the second bolt, fixes; Angular contact ball bearing is contained in inner ring gear, deep groove ball bearing is arranged on base, described gear and angular contact ball bearing are arranged on short main shaft, deep groove ball bearing is used for supporting short main shaft, described gear rotates by angular contact ball bearing and deep groove ball bearing, described gland is fixed on the spindle nose of short main shaft, is used for fixing angular contact ball bearing; Workbench is arranged on gear, is connected and fixed gear driven working table movement between described workbench and gear with the first bolt.
As a further improvement on the present invention, the inner ring of described gear and the outer ring of gland are provided with an outside framework oil seal, with oil-leakage-prevention.
Compared with prior art, advantage is in the present invention: simple in structure, ingenious, reasonable; Short base bearing loading capacity increases, and safety coefficient improves, reliable and stable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Figure 1, the first bolt 1, workbench 2, gland 3, gear 4, angular contact ball bearing 5, deep groove ball bearing 6, short main shaft 7, base 8, the second bolt 9 and outside framework oil seal 10.
A kind of short main axle structure of the present invention, described short main shaft 7 is arranged on base 8, fixing with the second bolt 9; Described angular contact ball bearing 5 is contained in gear 4 inner rings, deep groove ball bearing 6 is arranged on base 8, then gear 4 and angular contact ball bearing 5 are arranged on short main shaft 7, described deep groove ball bearing 6 is used for supporting short main shaft 7, described gear 4 is by angular contact ball bearing 5 and deep groove ball bearing 6 rotations, described gland 3 is fixed on the spindle nose of short main shaft 7, is used for fixing angular contact ball bearing 5; At the inner ring of gear 4 and the outer ring of gland 3, be provided with an outside framework oil seal 10, with oil-leakage-prevention; Described workbench 2 is arranged on gear 4, does with the first bolt, to be connected and fixed between platform 2 and gear 4 described in work, and gear 4 drives workbench 2 motions.
The present invention is simple in structure, ingenious, reasonable; It can realize short base bearing loading capacity increase, and safety coefficient improves, reliable and stable.
