Abstract
The utility model discloses a headstock device on a steel ball machine tool. The headstock device not only can rotate, but also can realize linear displacement, so that the contact ratio and the stability of two working die plates are ensured, and steel ball processing quality and steel ball accuracy grade are increased. The headstock device on the steel ball machine tool comprises an oil cylinder body, an oil cylinder front cover, an oil cylinder rear cover, a piston rod, a piston, a belt pulley, a belt pulley seat, a spline housing, a spline transmission disc, a transmission spindle, a rotating disc and a supporting bearing, wherein the piston rod is fixed on the oil cylinder body by the oil cylinder front cover and the oil cylinder rear cover; the piston is arranged in the piston rod; the transmission spindle is arranged in the piston rod through a bearing; the belt pulley and the spline housing are fixedly connected with each other through bolts; the rotating disc is arranged on the front end surface of the transmission spindle and is fixedly connected with the front end surface of the transmission spindle through screws; and the supporting bearing is arranged in the piston rod in the middle of the transmission spindle. A cylindrical roller bearing A and an angular contact bearing B are respectively arranged at the front end of the transmission spindle. The rest structure arrangement and the rest parts of the headstock device on the steel ball machine tool are similar to the structure arrangement and the parts in the prior art. The headstock device on the steel ball machine tool is an updated product of the conventional spindle transmission mechanism on a steel ball processing machine tool, and is beneficial to increasing the quality and the accuracy grade of processed products.
Description
Technical field
The utility model relates to a kind of steel ball lathe, particularly relates to the headstock device on a kind of steel ball lathe.
Background technology
Existing steel ball machining tool; Generally form by headstock device (or claiming spindle gearing), fixed mount and lathe bed three parts; Headstock device drives the final drive shaft rotation through belt pulley; Rolling disc is driven by final drive shaft and rotates, and the scratch diskette that drives on the fixed mount through spheroid rotates to realize cutting, the grinding to spheroid.Here fixed mount can move on lathe bed and headstock device is general only rotates and do not move as straight line; This version causes two registration, stationarities between the working template to can not get guaranteeing; The mixed-precision of the plate ditch between two templates leading is low, has a strong impact on the crudy and the precision of steel ball.
Summary of the invention
The purpose of the utility model is the headstock device that will provide on a kind of steel ball lathe, to improve the crudy and the precision of product.Headstock device on this novel steel ball lathe can adopt following technical scheme to implement: the headstock device on the steel ball lathe comprises cylinder body, oil cylinder protecgulum, oil cylinder bonnet, piston rod, piston, belt pulley, belt wheel seat, spline housing, spline drive plate, transmission main shaft, rolling disc and spring bearing; Wherein oil cylinder protecgulum and oil cylinder bonnet are fixed on piston rod on the cylinder body; Piston is installed in the piston rod; Transmission main shaft is installed in the piston rod through bearing; Belt pulley and spline housing are fixed on the belt wheel seat through the spline drive plate; Belt wheel seat and oil cylinder bonnet are fixed through Bolt Connection, and rolling disc is installed on the front end face of transmission main shaft and is fixedly connected through screw, in the piston rod in transmission main shaft centre position, spring bearing is housed.Cylinder roller bearing A and angular contact bearing B are contained in the transmission main shaft front end respectively.All the other structure arrangements of headstock device and parts on the steel ball lathe are similar with prior art.
Headstock device on the steel ball lathe of making according to technique scheme compared with prior art its main feature is:
1, the headstock device of the utility model not only rotates, and can realize that straight line moves, and can guarantee two registration, stationarities between the working template during work, guarantees the mixed-precision of plate ditch.Significantly improve the crudy and the accuracy class of steel ball.
2, in the piston rod in transmission main shaft centre position, spring bearing is housed, main shaft is played a supportive role, guarantee the transmission main shaft running steadily.
Description of drawings
Headstock apparatus structure sketch map on Fig. 1, the steel ball lathe.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done further narration.
As shown in Figure 1; Headstock device on the steel ball lathe comprises cylinder body 2, oil cylinder protecgulum 3, oil cylinder bonnet 4, piston rod 10, piston 5, belt pulley 6, belt wheel seat 11, spline housing 8, spline drive plate 9, transmission main shaft 7, rolling disc 1 and spring bearing 12; Wherein oil cylinder protecgulum 3 is fixed on piston rod 10 on the cylinder body 2 with oil cylinder bonnet 4; Piston 5 is installed in the piston rod 10, and transmission main shaft 7 is installed in the piston rod 10 through bearing, and belt pulley 6 and spline housing 8 are fixed through Bolt Connection; Rolling disc 1 is installed on the front end face of transmission main shaft 7 and is fixedly connected through screw, and spring bearing 12 is housed in the piston rod in transmission main shaft centre position.Cylinder roller bearing A 13 and angular contact bearing B 14 are contained in the transmission main shaft front end respectively.All the other structure arrangements of headstock device and parts on the steel ball lathe are similar with prior art.
According to the headstock device on the steel ball lathe of said structure making; Lean on belt pulley to drive the transmission main shaft rotation during work through the effect of spline; Rolling disc rotates with the rotation of transmission main shaft, and the effect through hydraulic oil, and piston is moved as straight line in oil cylinder; The final straight-line displacement that realizes headstock device, the operating principle and the prior art of all the other each parts are same or similar.
