Abstract
The utility model discloses a main shaft transmission device for a horizontal type milling and boring machine, which comprises a main shaft motor, a milling shaft, a boring shaft, a square sliding ram, a transmission box body and a main shaft box body, wherein the transmission box body is arranged at the upper part of the square sliding ram; the main shaft motor is arranged at the side of the transmission box body; a gear shaft is arranged at the upper part in the transmission box body; the tail part of the milling shaft in the square sliding ram is provided with a large gear; the large gear is connected with the gear shaft by an intermediate gear; and the lower part of the intermediate gear passes through openings respectively arranged at the lower part of the transmission box body and the upper part of the square sliding ram, and is connected with the large gear in a matching way. The main shaft transmission device is simplified, and the working noise of the device is reduced.
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 main shaft casing; 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 drive with the elongated splined shaft that is installed in the main shaft casing.Complex structure, rotate chain length, operating noise is high, is 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 technical problem of above-mentioned existence, the spindle gearing of the boring and milling machine with horizontal spindle that a kind of transmission device is simplified, operating noise reduces is provided.
The technical scheme of the utility model is: comprise spindle drive motor, milling spindle, boring axle, square ram, transmission case body, 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; Transmission case body is installed in ram top by the side; Spindle drive motor is installed in side at transmission case body, the top mounting teeth wheel shaft in the transmission case body, and gear shaft is connected with the output shaft of spindle drive motor; The afterbody of milling spindle is installed gear wheel in side's ram; Be connected through idler gear between gear wheel and the gear shaft, idler gear is installed on the jackshaft, and jackshaft is installed on the transmission case body; Transmission case body bottom and square ram top are provided with opening, and the bottom of idler gear passes opening part and gear wheel is connected.
The beneficial effect of the utility model is: owing to transmission case body is installed on square ram top; Spindle drive motor is installed in side at transmission case body; Jackshaft is installed in transmission case internal upper part mounting teeth wheel shaft, bottom; Idler gear is installed on the jackshaft, and stretch out from the opening of transmission case bottom the bottom of idler gear, is meshed with the gear wheel of the afterbody of milling spindle in the square ram.A complete set of main drive is all on the side's of being directly installed on ram; No longer be connected with the main shaft casing; The main drive structure of boring and milling machine with horizontal spindle 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 is the internal structure sketch map of the utility model;
Fig. 2 is the right view of Fig. 1.
The specific embodiment
Can find out that from internal structure sketch map of the utility model shown in Figure 1 and the right view of Fig. 2 the utility model mainly contains: compositions such as transmission case body 6, main shaft casing 7, spindle drive motor 9, gear shaft 5, jackshaft 3, idler gear 4, gear wheel 11, milling spindle 2, boring axle 1, square ram 10.The top of transmission case body 6 usefulness bolts and the taper pin side of being fastened on ram 10; Spindle drive motor 9 usefulness bolted are on the side of transmission case body 6; Be connected with no gap yielding coupling 8 with flat key between gear shaft 5 tops of usefulness roller bearings in transmission case body 6, gear shaft 5 and spindle drive motor 9.Jackshaft 3 is installed in the bottom in the transmission case body 6, and idler gear 4 usefulness rolling bearings are installed on the jackshaft 3, and the top of idler gear 4 is meshed with the gear of gear shaft 5, the bottom is meshed with gear wheel 11.Transmission case body 6 bottoms and square ram 10 tops all are provided with opening, and stretch out from the opening of transmission case body 6 bottoms the bottom of idler gear 4, and the opening through square ram 10 tops is meshed with gear wheel 11 again.Gear wheel 11 usefulness flat keys and round nut are installed in the afterbody of milling spindle 2, in the milling spindle 2 usefulness main shaft bearing side of the being installed in rams 10.Milling spindle 2 is hollow, and the front and rear portions of endoporus is equipped with sliding bearing sleeve respectively, in order to support boring axle 1; Two feather keys of symmetry are housed between milling spindle 2 and the boring axle 1; Through corresponding two featherways in boring axle surface, make boring axle 1 on milling spindle 2 synchronous operated bases, can also in milling spindle 2, stretch.Spindle drive motor 9 driven gear axles 5, the gear driven idler gear 4 of gear shaft 5, idler gear 4 drives the milling spindle 2 of gear wheel 11 and main spindle box, and milling spindle 2 is rotating simultaneously with 1 running of feather key drive boring axle.Side's ram 10 adopts existing mature technology to be supported in the main shaft casing 7, and it is flexible in main shaft casing 7, to drive main drive.
Because a complete set of main drive is all on the side's of being directly installed on ram; No longer be connected with the main shaft casing; 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.
