Abstract
The utility model relates to a change gear mechanism of a lathe, which comprises an output shaft of a main shaft box, transmission shafts and an input shaft of a feeding box, wherein transmission gears are respectively arranged on the output shaft of a main shaft box, the transmission shafts and the input shaft of a feeding box. The utility model is characterized in that the utility model is provided with an upper and a lower transmission shaft, and duplicate gears are respectively arranged on the upper and the lower transmission shafts, wherein the duplicate gear on the upper transmission shaft can be respectively engaged with a duplicate gear on the output shaft of a main shaft box and the duplicate gear on the lower transmission shaft. A single gear is also arranged on the lower transmission shaft, and a gear is also arranged on the input shaft of a feeding box, wherein the gear can be engaged with the single gear on the lower transmission shaft. The utility model has the advantage that under the condition of keeping the change gear of the prior art to be unchanged, a shaft 9 and a pair of gears 6, 8 only need to be additionally arranged. The positions of the gears can also be interchanged, so that a gear ratio can be 1/2 or 2/1, therefore the function of expanding thread pitch for four times can be realized. Therefore, the utility model not only can realize the conversion functions of the existing thread kinds (a metric system, an English system, modulus and diametral pitch), but also can realize the function of expanding the thread pitch simultaneously.
Description
Technical field
The utility model relates to a kind of Pulley mechanism of lathe transmission mechanism, particularly lathe.
Background technology
The Pulley mechanism of lathe only is the conversion that is used for realizing the cutted thread kind, and does not enlarge the function of pitch at present.The Pulley mechanism of at present common lathe includes only main spindle box output shaft, power transmission shaft and feed box power shaft, realizes the change gear speed changes by three duplicate gears being located at respectively on main spindle box output shaft, power transmission shaft and the feed box power shaft.Therefore at present general common middle-size and small-size horizontal lathe does not all have the pitch expanded functionality, so engine lathe also just can not be processed the screw thread of coarse pitch.Certainly, the lathe that can enlarge pitch is arranged also on the market, the lathe of this function, its pitch enlarges mechanism and is provided in a side of in the main spindle box, the structure more complicated, the cost height, price is big.Come for some small enterprises, equipment is incomplete mostly, only has engine lathe, as processing the screw thread of coarse pitch, is exactly a difficult problem, needs cooperation processing.How on the basis of existing engine lathe, to improve, make common lathe also can process steep-pitch thread, to adapt to the demand of middle-size and small-size machine industry.
Summary of the invention
Technical barrier to be solved of the present utility model is, overcomes the deficiencies in the prior art, and a kind of lathe Pulley mechanism is provided, as long as carry out some little improvement in the Pulley mechanism of existing engine lathe, just can make engine lathe also can process steep-pitch thread.
Technical solution of the present utility model is: comprise main spindle box output shaft, power transmission shaft and feed box power shaft, be respectively equipped with travelling gear on main spindle box output shaft, power transmission shaft and the feed box power shaft, it is characterized in that, have upper and lower two power transmission shafts, be respectively equipped with duplicate gear on the upper and lower power transmission shaft, the duplicate gear on the last power transmission shaft can be respectively with the main spindle box output shaft on duplicate gear and the engagement of the duplicate gear on the lower drive shaft; Lower drive shaft is provided with an individual gears, also is provided with a gear that can be meshed with the individual gears on the lower drive shaft on the feed box power shaft.
On the lower drive shaft and on the feed box power shaft can intermeshing individual gears gear ratio be 1/2.
On the lower drive shaft and on the feed box power shaft can intermeshing individual gears gear ratio be 2/1.
The utility model advantage compared with prior art is, keeping under the constant situation of prior art change gear, setting up an axle and a pair of gear ratio and be 1/2 gear, the position of this a pair of gear is also interchangeable, make gear ratio become 2/1 again, thereby realize 4 times pitch expanded functionality.So the utility model both can have been realized the mapping function of current screw thread kind (metric system, English system, modulus, diametral pitch), can realize enlarging simultaneously the function of pitch again, can enlarge 4 times.
Description of drawings
Fig. 1 is that structure of the present utility model is launched schematic diagram.
Number in the figure: 1-main spindle box output shaft, 2-duplicate gear, 3-duplicate gear, 4-duplicate gear, the last power transmission shaft of 5-, 6-individual gears, 7-lower drive shaft, 8-individual gears, 9-feed box power shaft.
Concrete implementing method
The utility model comprises main spindle box output shaft 1, two power transmission shafts 5,7 and feed box power shaft 9 up and down, is respectively equipped with duplicate gear 2/3 on main spindle box output shaft 1 and the last power transmission shaft 5.Establish three gears on the lower drive shaft 7, a duplicate gear 4 and an individual gears 6, feed box power shaft 9 is provided with an individual gears 8.Its drive path is: main spindle box output shaft 1-Z2/Z3-Z3/4-Z6/Z8 one feed box power shaft 9.Gear 6 and gear 8 can exchange as required, and its gear ratio is respectively: Z6/Z8=1/2, Z8/Z6=2/1.
The utility model is the improvement of carrying out on the basis of existing technology, has in fact only set up an axle 9 and a pair of gear 6,8 on the basis of existing technology.Lower drive shaft 7 is the feed box power shaft in the prior art, and the feed box power shaft is the axle of newly establishing 9 in the utility model, and lower drive shaft 7 has become power transmission shaft.The utility model accompanying drawing is that a structure is launched schematic diagram, and the installation dimension of main spindle box output shaft 1 and feed box power shaft 9 and prior art are less than changing in the actual end view, and it must adapt with the installation site size of main spindle box output shaft and feed box power shaft.
Claims (3)
1, a kind of lathe Pulley mechanism, comprise main spindle box output shaft, power transmission shaft and feed box power shaft, be respectively equipped with travelling gear on main spindle box output shaft, jackshaft and the feed box power shaft, it is characterized in that, have upper and lower two jackshafts, be respectively equipped with duplicate gear on the upper and lower power transmission shaft, the duplicate gear on the last power transmission shaft can be respectively with the main spindle box output shaft on duplicate gear and the engagement of the duplicate gear on the lower drive shaft; Following jackshaft is provided with an individual gears, also is provided with a gear that can be meshed with the individual gears on the lower drive shaft on the feed box power shaft.
