Abstract
The utility model discloses a main transmission device for a ram spindle box of a milling and boring machine. The device comprises a spindle motor, a motor base, a milling shaft, a boring shaft, a square ram and a spindle box body, wherein the spindle motor is fastened on one side of the motor base through a connecting disc; the motor base is fastened on the upper part of the square ram; the spindle motor drives a big belt pulley on the tail part of the milling shaft through belt transmission; and a belt adjustment bolt is arranged between the upper part of the connecting disc and the top of the motor base. By the device, the structure is remarkably simplified, the working noise is reduced, and the working speed, accuracy and reliability are improved.
Description
Technical field
The utility model belongs to the Metal Cutting Machine Tool field, especially relates to the spindle gearing of a kind of boring and milling machine with horizontal spindle side ram type main spindle box.
Background technology
In the main axis transmission system of tradition boring and milling machine with horizontal spindle side ram type main spindle box; Spindle drive motor is installed on the casing of main spindle box; Through being installed in many rooted teeth wheel shaft on the main shaft casing, overpaying travelling gear; Be transferred to earlier on the gear in the side's of being installed in ram upper gear bag, again by the gear drive in the gear bag to the gear wheel of milling spindle afterbody, drive main axis rotation.Because the gear bag need be done moving of big distance with square ram flexible in the main shaft casing, so the gear in the gear bag, need be with driving on the elongated splined shaft that is installed in the main shaft casing.Complex structure, operating noise are big, maintenance difficult, are not easy to further improve speed, precision and the reliability of spindle operation.
Summary of the invention
The purpose of the utility model is: to the problem of above-mentioned existence, a kind of main drive of milling-boring machine ram main spindle box is provided, simplifies transmission device, reduce operating noise, improve working speed, precision and reliability.
The technical scheme of the utility model is: comprise spindle drive motor, motor cabinet, milling spindle, boring axle, square ram, main shaft casing; Between the boring axle of milling spindle and inside feather key is housed, square ram is supported in the main shaft casing, and spindle drive motor is fastened on the terminal pad; Terminal pad is fastened on the side of motor cabinet; Small pulley is installed on the output shaft of spindle drive motor in the top of the motor cabinet side of being fastened on ram, and the afterbody of milling spindle is installed big belt wheel; Between the big small pulley, the bottom of motor cabinet and the top of square ram is provided with opening, belt is connected on the big small pulley through opening part; Be provided with belt adjustment bolt between terminal pad top and the motor cabinet top.
The beneficial effect of the utility model is: because the motor cabinet that the installation spindle drive motor is used on square ram top; Spindle drive motor is installed in side at motor cabinet; On the output shaft of spindle drive motor small pulley is installed, the afterbody of milling spindle is installed big belt wheel in square ram, and a complete set of main drive is all on the side's of being directly installed on ram; No longer be connected, directly use belt transmission between spindle drive motor and the main shaft with the main shaft casing.Transmission structures is obviously simplified, both reduced the operating noise of this device, also satisfied the higher rotating speed of this main drive, more accurate demand reliably.
Description of drawings
Fig. 1 looks sketch map for the master of the utility model;
Fig. 2 is the right view of Fig. 1.
The specific embodiment
Look the right view of sketch map and Fig. 2 from the master of Fig. 1 the utility model and can find out that the utility model mainly contains: compositions such as spindle drive motor 8, spindle motor terminal pad 7, belt adjustment bolt 6, motor cabinet 5, small pulley 4, driving belt 3, big belt wheel 12, standard ringfeder 11, main spindle front bearing 1, mainshaft rear bearing 13, milling spindle 2, boring axle 10, square ram 9.The top of motor cabinet 5 usefulness bolts and the taper pin side of being fastened on ram 9, spindle drive motor 8 usefulness bolted are on spindle motor terminal pad 7, and spindle motor terminal pad 7 is fastened on the side of motor cabinet 5.According to prior art; Boring axle 10 is supported in the milling spindle 2; Milling spindle 2 is supported on main spindle front bearing 1 and the mainshaft rear bearing 13, and two feather keys of symmetry are housed between milling spindle 2 and the boring axle 10, through corresponding two featherways in boring axle surface; Make boring axle 10 on, can also in milling spindle 2, stretch with milling spindle 2 synchronous operated bases.Side's ram 9 adopts existing mature technology, be supported in the main shaft casing 14, and it is flexible in main shaft casing 14, to drive main drive.Small pulley 4 is installed on the output shaft of spindle drive motor 8, and the afterbody of milling spindle 2 is installed with big belt wheel 12 with standard ringfeder 11.Between the big small pulley, the bottom of motor cabinet 5 and the top of square ram 9 all has opening, driving belt 3 is connected on the big small pulley through opening part, directly uses the one-level belt transmission between the big small pulley.Between spindle motor terminal pad 7 tops and motor cabinet 5 tops, be provided with belt adjustment bolt 6, belt adjustment bolt 6 can be adjusted the height of spindle motor terminal pad 7 and spindle drive motor 8 relative motor cabinets 5, so that the initial tensile force of adjustment driving belt 3.
The utility model is because motor cabinet 5 and spindle drive motor 8 all on the side's of being directly installed on ram 9; Spindle drive motor 8 is directly with one-level belt drives milling spindle 2 and 10 revolutions of boring axle; The main drive structure of boring and milling machine with horizontal spindle ram type main spindle box is obviously simplified; Both reduced the operating noise of this device, also satisfied the higher rotating speed of this main drive, more accurate demand reliably.
