Abstract
The utility model relates to a gun drill drilling mechanism. The gun drill drilling mechanism comprises a support seat (1), a drilling main shaft (2), a tool bar (3), a drill casing (4), a drill casing seat (5), a gas-liquid damper (6) and a main shaft motor (8). The drilling main shaft (2) is mounted on the support seat (1) and connected with the main shaft motor (8) through a belt, and the other end of the drilling main shaft (2) is provided with the tool bar (3); the drilling casing is mounted at the front end of the drill casing seat (5); the drill casing seat (5) is slidingly mounted on a drill casing sliding rail (7); the drill casing sliding rail (7) is fixedly mounted on the upper portion of the support seat (1); one end of the gas-liquid damper (6) is fixed to the support seat (1), and the other end of the gas-liquid damper (6) exerts damping on the drill casing seat (5). The gun drill drilling power mechanism has the advantages that the drill casing and the drill bar can maintain good concentricity in motion, the workpiece injection damping force of the drill casing is adjustable, and drilling stability and high efficiency can be achieved.
Description
Technical field
The utility model relates to a kind of boring power unit, particularly drill gun drilling head mechanism.
Background technology
Drill gun requires strict to main axial shifting amount, conventionally should be limited in 0.003mm, requires the main shaft bearing nonfailure operating time long, and general cannot meet this high accuracy, high efficiency requirement at drilling sector.And in boring procedure, the cutting oil mist of oil of high pressure cutting oil system ejection is larger, healthy unfavorable to human body.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, safe drill gun drilling actuating unit when providing that a kind of borehole accuracy is high, rate of penetration is fast and reduces labour intensity.
The purpose of this utility model is achieved through the following technical solutions: drill gun drilling actuating unit, it comprises bearing, drilling main shaft, knife bar, drill bushing, drill bushing seat, gas-liquid damping, drill bushing slide rail and spindle motor, drilling main shaft is arranged on bearing, drilling main shaft is connected with spindle motor by belt, the other end of drilling main shaft is provided with knife bar, drill bushing is arranged on drill bushing seat front end, drill bushing seat is slidably mounted on drill bushing slide rail, drill bushing slide rail is fixedly mounted on the top of bearing, gas-liquid damping unit one end is fixed on bearing, the other end of gas-liquid damping unit applies damping to drill bushing seat.
Described knife bar is communicated with outside high pressure cutting oil.
The utlity model has following advantage:
1, drilling main shaft adopts bearing and the lubricating grease of German import, and designed complex maze hermetically-sealed construction, prevent that bearing grease from escaping when running up, and effectively prevent that foreign matter and cutting oil from entering, the axial movement value of adjusting drilling main shaft 2 during assembling is less than 0.003 millimeter, and the precision of boring is high.
Thereby power when 2, drill bushing is from workpiece pre-tightening can regulate different pretightning forces to obtain different rigidity by gas-liquid damping unit.
3, because drill bushing is all the time by gas-liquid damping unit and workpiece pretension, make high pressure cutting oil cannot form a large amount of mist of oils, reduce the possibility that mist of oil threatens to operating personnel's health.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-bearing, 2-drilling main shaft, 3-knife bar, 4-drill bushing, 5-drill bushing seat, the damping of 6-gas-liquid, 7-drill bushing slide rail, 8-spindle motor.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1, drill gun drilling actuating unit, it comprises bearing 1, drilling main shaft 2, knife bar 3, drill bushing 4, drill bushing seat 5, gas-liquid damping 6, drill bushing slide rail 7 and spindle motor 8, drilling main shaft 2 is arranged on bearing 1, drilling main shaft 2 is connected with spindle motor 8 by belt, the other end of drilling main shaft 2 is provided with knife bar 3, drill bushing 4 is arranged on drill bushing seat 5 front ends, drill bushing seat 5 is slidably mounted on drill bushing slide rail 7, drill bushing slide rail 7 is fixedly mounted on the top of bearing 1, gas-liquid damping unit 6 one end are fixed on bearing 1, the other end of gas-liquid damping unit 6 applies damping to drill bushing seat 5.
Described knife bar 3 is communicated with outside high pressure cutting oil.Drill bushing 4 all the time with workpiece pretension, make cutting oil cannot form a large amount of mist of oils, reduce the possibility that mist of oil threatens to operating personnel's health.
Described drilling main shaft 2 adopts bearing and the lubricating grease of German import, and designed complex maze hermetically-sealed construction, prevent that bearing grease from escaping when running up, and effectively prevent that foreign matter and cutting oil from entering, the axial movement value of drilling main shaft 2 is less than 0.003 millimeter.
