Abstract
The utility model discloses main shaft structure of a drill hole. A system controls a main shaft actuating motor to rotate at a high speed. A high-speed main shaft rotates at a high speed through a synchronous pulley and a synchronous belt. Due to the fact that a main shaft box is a welding integral, a main shaft does not easily shake in drilling. When cutting tools on the high-speed main shaft need to be replaced, the system controls the main shaft actuating motor to enable the high-speed main shaft to rotate to a specific angle through induction of an induction switch, and then a piston drive head of a pneumatic boosting cylinder moves downwards to enable the cutting tools of the high-speed main shaft to automatically drop. After the cutting tools are replaced, the piston drive head of the pneumatic boosting cylinder moves upwards, and clamping of the cutting tools of the high-speed main shaft is completed. The main shaft box of the main shaft structure of the drill hole is of an integrated structure, and accordingly installation and adjusting are convenient, service life of machine tool equipment is prolonged, the automation degree of the machine tool is improved due to the fact that automatic knife replacement structure is adopted, and production efficiency is improved.
Description
Technical field
The utility model relates to the plant equipment field, the drill spindle structure that especially a kind of digital control hole drilling cutting unit mahine can carry out tool changing.
Background technology
In the main shaft driving structure of introducing in the prior art " spindle drive of ZL201120081542.8---numerical control drilling-milling bed "; Spindle drum and motor cabinet are split-type structural; In the work of high-speed main spindle, be easy to generate vibrations, and the installation adjustment is cumbersome, the function of no automatic tool changer.
The utility model content
The applicant is to shortcomings such as above-mentioned split-type structural difficult installation; A kind of spindle drum and motor cabinet integral type are provided; And having the drill spindle structure of automatic tool changer function, the characteristics of integral structure are that machining accuracy is guaranteed by machined fully, need not adjustment during assembling; Improved transmission accuracy effectively, more steadily reliable when making work; The automatic tool changer function has improved automation degree of equipment.
The technical scheme that the utility model adopted is following:
A kind of drill spindle structure; High-speed main spindle be installed in main spindle box below; Knife striking cylinder is installed in the top of main spindle box and concentric with high-speed main spindle, and the main axle servo motor is installed in the front of main spindle box through motor mounting plate, and adjustable plate is installed in the front end of main spindle box; The adjusting bolt that nut is housed connects motor mounting plate and adjustable plate; Synchronous pulley is installed on the main axle servo motor output shaft with block, and band connects the belt wheel place of synchronous pulley and high-speed main spindle respectively synchronously, and the switch bracket that inductive switch is installed is installed in the side of main spindle box.
Further improvement as technique scheme: said main spindle box is welded into an integral body by side steel plate, top board, bloom, bar steel plate, base plate, end plate.
The beneficial effect of the utility model is following:
The main spindle box of the utility model setting has adopted integral structure, makes install adjustment convenient, has improved the service life of machine tool, has adopted the structure of automatic tool changer to make the automaticity of lathe increase, and production efficiency also has raising.
Description of drawings
Fig. 1 is the front view of the utility model.
Fig. 2 is the A-A cutaway view among Fig. 1.
Fig. 3 is the vertical view of Fig. 1.
Among the figure: 1, high-speed main spindle; 2, main spindle box; 3, knife striking cylinder; 4, main axle servo motor; 5, motor mounting plate; 6, adjustable plate; 7, regulate bolt; 8, nut; 9, synchronous pulley; 10, block; 11, be with synchronously; 12, cover plate; 13, switch bracket; 14, inductive switch; 15, side cover plate; 21, steel plate; 22, top board; 23, bloom; 24, bar steel plate; 25, base plate; 26, end plate.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described.
Extremely shown in Figure 3 like Fig. 1; The described main spindle box 2 of the utility model is welded into an integral body by two blocks of side steel plates 21, top board 22, a bloom 23, two blocks of bar steel plates 24, base plate 25, an end plate 26, around all have decoration hole, installing hole and machined surface.High-speed main spindle 1 usefulness screw be installed in main spindle box 2 below; Knife striking cylinder 3 usefulness screws be installed in main spindle box 2 above; And concentric with high-speed main spindle 1, main axle servo motor 4 usefulness screws are installed on the motor mounting plate 5, and motor mounting plate 5 usefulness screws are installed in the front of main spindle box 2; Adjustable plate 6 is installed in the front end of main spindle box 2; The adjusting bolt 7 that nut 8 is housed connects motor mounting plates 5 and adjustable plates 6, and synchronous pulley 9 usefulness blocks 10 are installed on main axle servo motor 4 shafts, synchronously with 11 connect synchronous pulley 9 and high-speed main spindle 1 respectively the belt wheel place; The switch bracket 13 that inductive switch 14 is installed is installed in the side of main spindle box 2 through screw, and cover plate 12 is installed in front and two sides respectively with side cover plate 15.
During real work, system control main axle servo motor 4 high speed rotating, through synchronous pulley 9 be with 11 to make high-speed main spindle 1 rotation at a high speed synchronously because main spindle box 2 is a welding integral, main shaft is not easy generation and shakes when drilling work; When needs are changed the cutting tool on the high-speed main spindle 1; Digital control system control main axle servo motor 4 makes high-speed main spindle 1 turn to special angle through the induction of inductive switch 14; The piston of knife striking cylinder 3 is taken the lead to move downward and is made the cutting tool of high-speed main spindle 1 fall automatically then; After cutter was accomplished replacing, the piston of knife striking cylinder 3 was taken the lead and is moved upward, and the cutting tool of high-speed main spindle 1 is accomplished clamping.
More than describing is the explanation to the utility model, is not the qualification to utility model, and the utility model institute restricted portion is referring to claim, and under the situation of the utility model spirit, the utility model can be done any type of modification.
