Compared with prior art, the utility model has the advantages that:
(1) main shaft lifting length extends, and the batch machining ability of 200 millimeter deep holes can be provided, and deep hole machining efficient improves more than three times;
(2) need not frequent lifting fuselage in the process, save time, laborsaving, power saving, can reduce the damage of drilling machine column;
(3) because of need not frequent lifting fuselage, depart from probability and reduce so the hole is positioned at bit central, the possibility that drill bit fractures is lowered;
(4) adopt the form that spline housing is embedded and rack sleeve is interior, make that when travel of spindle increased, the animal economy height change was little.
Simultaneously, the utility model also has advantages such as simple in structure, easy to operate, safe and efficient, long service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A profile of Fig. 1;
Fig. 3 is the B-B profile of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model being done one describes in detail.
Referring to Fig. 1, wherein: 1, main shaft; 2, driving key; 3, bearing (between spline housing and the main shaft installation frame body top); 4, positioning sleeve; 5, alignment pin; 6, outer snap ring (location bearing); 7, spline housing; 8, main shaft installation frame body; 9, outer snap ring (rack sleeve middle part, location bearing); 10, bearing (rack sleeve middle part); 11, rack sleeve; 12, bearing (rack sleeve lower port); 13, gasket ring; 14, lower cover 15, drill chuck; 16, base; 17, control crank; 18, column; 19, lifting handwheel; 20, motor; 21, belt housing; 22, belt; 23, compress knob 24, negative pulley wheel; 25, outer snap ring (location negative pulley wheel).
As shown in Figure 1, spline housing (7) is placed in the mesopore of negative pulley wheel (24), link with driving key (2) between them, negative pulley wheel (24) is location between snap ring (25) and the spline housing (7) in addition, the spline segment of main shaft (1) penetrates in the spline housing, keyway on main shaft (1) outer surface is meshed with the driving key that spline housing (2) inwall is fixedly connected, be provided with bearing (3) between spline housing (2) and main shaft installation frame body (8) top, bearing (3) positioning sleeve (4), alignment pin (5) and outer snap ring (6) location, main shaft (1) be positioned at the following part of spline segment through being located at rack sleeve (11) lower port bearing (10) and the bearing (12) at rack sleeve (11) middle part connect with rack sleeve (11), snap ring (6) location beyond between bearing (10) and the main shaft (1), locate with gasket ring (13) between bearing (12) and the main shaft (1), and the lower port of rack sleeve (11) is sealed with lower cover (14).
As can see from Figure 1, compared with prior art, rack sleeve of the present utility model (11) length increases, be arranged on its surperficial tooth bar also extends thereupon, but the relative position of bearing position is constant, bearing (10) is ensconced in the rack sleeve deeply, for the assembling maintenance that makes bearing (10) becomes possibility, assembles window so open a snap ring at the place, bearing position, middle part of rack sleeve (11); The spline segment lengthening of corresponding main shaft (1), spline housing (7) also extends, and spline housing (7) forms insert structure with rack sleeve (11), makes the overall height of drilling machine change little.Because the growth of main shaft (1), spline housing (7) and rack sleeve (11) makes main shaft (1) stroke increase, drilling depth is also with regard to corresponding intensification.
During work, under the effect of motor (20), belt (22) drives negative pulley wheel (24) and spline housing (7) rotate together, the effect of the driving key that is fixedly connected because of spline housing (7) inwall, and the main shaft that makes (1) also rotates thereupon together, has realized the rotating shaft campaign; Rotate counterclockwise control crank (17) and can make rack sleeve (11) realize downward motion, under the promotion of bearing (12) and gasket ring (13), main shaft (1) is descending with rack sleeve (11), and workpiece is holed; Clockwise rotate control crank (17) and can make rack sleeve (11) and main shaft (1) up together, drill bit is deviate from from boring, carries out furfur.
