Abstract
The present invention relates to a tailstock apparatus with a speed changing apparatus for a machine tool, which is characterized in that a hand wheel on a tailstock is arranged on a hand wheel shaft, a speed changing box is arranged between a screw rod and a hand wheel shaft, the screw rod, the hand wheel shaft and a driving shaft are arranged in the speed changing box, a pair of engaging and disengaging gears with end-surface teeth are arranged on the screw rod and the hand wheel shaft, and two driving gears is arranged on the driving shaft. When the power of the hand wheel shaft is directly transmitted to the screw rod, the equal-ratio drive of 1:1 can be realized; when the power of the hand wheel shaft is then transmitted to the screw rod through the driving shaft, the speed-changing drive of 1:4 can be realized. The present invention with speed-changing drive can save labor and reduce the labor intensity of workers wrenching a hand wheel.
Description
Technical field
The present invention relates to a kind of tailstock of lathe, particularly a kind of in, the tailstock device that has speed change gear of heavy horizontal lathe.
Background technology
At present, the tailstock of lathe does not have gear, and handwheel directly is located on the leading screw, and the transmission of tailstock is directly pulled leading screw by handwheel, is moved by leading screw drive feed screw nut and sleeve.When need utilized tailstock to carry out the drilling large diameter hole, the operator need adopt boosting-rod to pull handwheel usually, and its labour intensity is very big.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the deficiency that handwheel power in the prior art can't speed change, and a kind of lathe tailstock device that has speed change gear is provided.
Technical solution of the present invention is, be provided with tailstock body, be provided with leading screw in the tailstock body, the afterbody of tailstock is provided with handwheel, it is characterized in that: the right side of leading screw also is provided with a hand wheel shaft, handwheel is located on the hand wheel shaft, is provided with gearbox between leading screw and the handwheel, and gearbox is made of leading screw, hand wheel shaft, power transmission shaft and end face clutch gear and travelling gear.
Described gearbox is provided with gear box, the axle head of leading screw and hand wheel shaft stretches in the gear box respectively, also be provided with power transmission shaft in its casing, but be respectively equipped with gear a pair of clutch, that have the end face tooth on the axle head of leading screw and hand wheel shaft, end face gear on the hand wheel shaft is an end face tooth shifting slide gear, power transmission shaft is provided with two travelling gears, can be respectively with leading screw on end face gear and the engagement of the end face tooth shifting slide gear on the hand wheel shaft.
End face tooth shifting slide gear on its hand wheel shaft can be stirred slippage by shift fork and shift fork handle.
Advantage of the present invention is, the handwheel power of tailstock can be realized the power transmission of two kinds of gearratios of 1: 1 or 1: 4, when the end face tooth shifting slide gear on the hand wheel shaft is selected directly and during the end face gear engaged transmission on the leading screw, hand wheel shaft and leading screw are transmission in 1: 1; Travelling gear engagement on selection of the end face tooth shifting slide gear on the hand wheel shaft and power transmission shaft, by another gear on the power transmission shaft and the engagement of the end face gear on the leading screw, hand wheel shaft and leading screw are realized 1: 4 laborsaving transmission again.When 1: 4 gearratio of selection, can make the handwheel power energy saving.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the right view of Fig. 1.
Number in the figure: 1-tailstock body, 2-leading screw, 3-end face gear, 4-end face tooth shifting slide gear, 5-gearbox, 6-hand wheel shaft, 7-handwheel, 8-travelling gear, 9-power transmission shaft, 10-travelling gear, shift fork 11, shift fork handwheel 12.
The specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing:
The embodiment of the invention is with the example that is applied as on CY6140 type medium heavy lathe.Be provided with tailstock body 1, be provided with leading screw 2 in the tailstock body 1, the afterbody of tailstock body 1 is provided with handwheel 7, and handwheel 7 is located on the hand wheel shaft 6, and hand wheel shaft 6 is located at the right side of leading screw 2, and the axial line of the axial line of hand wheel shaft 6 and leading screw 2 is positioned on the same axis.Be provided with gearbox 5 between tailstock body 1 and the handwheel 7, be provided with the gear 3,4 and the travelling gear 8,10 of leading screw 2, hand wheel shaft 6, power transmission shaft 9 and band edge face tooth in the casing of gearbox 5.
The axle head of leading screw 2 and hand wheel shaft 6 stretches into respectively in the gearbox 5, but be respectively equipped with gear 3,4 a pair of clutch, that have the end face tooth on the axle head of leading screw 2 and hand wheel shaft 6, end face gear 3 on the leading screw 2 is a fixed gear, and the end face gear on the hand wheel shaft 6 is an end face tooth shifting slide gear 4.Power transmission shaft 9 is provided with two fixing travelling gears 10,8, can be respectively with leading screw 2 on end face gear 3 and 4 engagements of the end face tooth shifting slide gear on the hand wheel shaft 6.
End face tooth shifting slide gear 4 on its hand wheel shaft 6 can be stirred slippage by shift fork 11.Shift fork 11 is by 12 controls of shift fork handwheel.
By stirring the end face tooth shifting slide gear 4 on the hand wheel shaft 6, can make the power transmission of handwheel 7 power realization 1: 1 or 1: 4 two kinds of gearratio.When the end face tooth shifting slide gear on the hand wheel shaft 64 select directly with leading screw 2 on end face gear when meshing 3 transmissions, hand wheel shaft 6 and leading screw 2 are transmission in 1: 1; Travelling gear 8 engagements on 4 selections of the end face tooth shifting slide gear on the hand wheel shaft 6 and power transmission shaft 9, during again by another travelling gear 10 on the power transmission shaft 9 and end face gear 3 engagements on the leading screw 2, hand wheel shaft 6 and leading screw 2 can be realized 1: 4 variator drive ratio.When selecting 1: 4 gear ratio, can make the rotary power on the handwheel 7 very laborsaving, light.
