Abstract
The invention discloses a drilling spindle structure. A system controls a spindle servo motor to rotate at a high speed, a high-speed spindle rotates at a high speed by the aid of a synchronous belt pulley and a synchronous belt, and the spindle is not easy to vibrate in drilling as a spindle box is integrally welded. When a cutter on the high-speed spindle needs to be replaced, the system controls the spindle servo motor so that the high-speed spindle rotates to a specific angle by means of induction of an inductive switch, and then a piston unclamping head of an unclamping cylinder moves down so that the cutter of the high-speed spindle automatically falls down. When the cutter is replaced, the piston unclamping head of an unclamping cylinder moves up, and the cutter of the high-speed spindle is clamped. The spindle box is of an integral structure so as to be more convenient in installation and adjustment, the service life of a machine tool is prolonged, the automation degree of the machine tool is improved by the aid of an automatic tool changing structure, and production efficiency is also improved.
Description
Technical field
The present invention 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.
Summary of the invention
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 present invention 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.
Beneficial effect of the present invention is following:
The main spindle box of setting of the present invention 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 a front view of the present invention.
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 present invention is described.
To shown in Figure 3, main spindle box 2 of the present invention 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 like Fig. 1, 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 to explanation of the present invention, is not that institute of the present invention restricted portion is referring to claim to the qualification of invention, and under the situation of spirit of the present invention, the present invention can do any type of modification.
