Abstract
The utility model discloses a radial feed mechanism for the sliding plate of the main shaft of a jig grinder, which includes a right ball screw assembly driven by a power input device, a bridge plate which is guided by a linear guideway is mounted outside the nut of the right ball screw assembly, which is connected with the nut of a left ball screw assembly via the bridge plate, the screw rod of the left ball screw assembly is connected with a transmission shaft and rotate, the lower end of the transmission shaft is connected with a pair of output bevel gears which are also nuts, and the bevel gears are rotationally engaged with the screw rods and driven by the rotation of the transmission shaft to drive the sliding plate to move. Compared with the prior power transmission method utilizing a lever structure or a crank link structure added with sliding keys, the radial feed mechanism does not generate deflective torque, transmission precision is high, the rigidity of the mechanism is greatly increased, and processing and assembly are easy.
Description
Technical field
The utility model relates to the machining equipment technical field, exactly relates to a kind of follow-on jig grinder main shaft slide plate depth-feed mechanism.
Background technology
At present, Chang Yong jig grinder slide plate depth-feed mechanism mainly adopts feed screw nut to drive.The drive connection of the jig grinder slide plate depth-feed mechanism that feed screw nut drives is: the U spindle motor is placed on the bistrique box top and directly drives ball screw, by ball screw rotation is converted into rectilinear motion is driven the bistrique box top by ball-screw nut big lever swing.By ball spline swing is changed into the rotation of power transmission shaft by the U shaft ball screw.The minor leading screw of slide plate being passed in rotation at the lower end of power transmission shaft bevel-gear sett changes into the straight-line feed of U axle.Wherein: motion one is promptly driven the big lever swing of bistrique box top by ball-screw nut; Motion two is the rotation that the U shaft ball screw changes into swing by ball spline power transmission shaft.Two motions drive the screw set moving linearly by lever swing by slide block and realize.The shortcoming of its existence is: when main shaft has main axis rotation motion simultaneously and moves back and forth, be to add the slide key transferring power by lever construction with the power input of upper type, be easy to generate deflection torque, transmission accuracy is low, and processing and assembly difficulty are big.
The utility model content
The utility model is intended at above-mentioned the deficiencies in the prior art, a kind of deflection torque, jig grinder main shaft slide plate depth-feed mechanism that transmission accuracy is high of can not producing is provided, the utility model adopts two secondary ball-screws, line slideway to give bevel gear with transmission of power, greatly improved mechanism's rigidity, processing and assembly difficulty are little.
For solving the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of jig grinder main shaft slide plate depth-feed mechanism, comprise the right side ball screw assembly, that drives with power input device, the nut of right side ball screw assembly, is equipped with the bridge plate by the line slideway guiding outward, described bridge plate connects the nut of left side ball screw assembly,, the leading screw of described left side ball screw assembly, connects power transmission shaft and rotates, the lower end of power transmission shaft is provided with bevel-gear sett, and described bevel gear is provided with the bevel gear nut with the screw mandrel engaged transmission of below, and screw mandrel rotates and also drives skateboarding.
Described power input device is hydraulic motor, air pressure motor, hydraulic cylinder, pneumatic cylinder or motor.
Advantage of the present utility model is:
1, because the utility model adopts two secondary ball screw assembly,s and line slideway to give bevel gear with transmission of power, add slide key transferring power mode by lever construction and compare with existing, be not easy to produce the deflection moment of torsion, the transmission accuracy height, greatly improved mechanism's rigidity, processing and assembly difficulty are little.
2, because the utility model has been cancelled the bearing of original leverage, reduced the volume of mechanism, for the improvement of other structure provides the space.

The specific embodiment
Embodiment 1
A kind of jig grinder main shaft slide plate depth-feed mechanism, comprise the right side ball screw assembly, 1 that drives with power input device 9, the nut of right side ball screw assembly, 1 is equipped with the bridge plate 3 by line slideway 2 guiding outward, described bridge plate 3 connects the nut of left side ball screw assembly, 4, the leading screw of described left side ball screw assembly, 4 connects power transmission shaft 5 and rotates, the lower end of power transmission shaft 5 is provided with bevel-gear sett 6, described bevel gear 6 is provided with the bevel gear nut 8 with screw mandrel 7 engaged transmission of below, and screw mandrel 7 rotates and also drives skateboarding.Described power input device 9 is hydraulic motor, air pressure motor, hydraulic cylinder, pneumatic cylinder or motor.
Embodiment 2
The utility model adopts two secondary ball-screws, line slideway 2 to give bevel gear 6 with transmission of power, integrated nut on the bevel gear 6 simultaneously, and the screw mandrel 7 that drives the below rotates, and finally drives skateboarding by screw mandrel 7.Because power transmission shaft 5 and main shaft have slide key, make the jig grinder main shaft move up and down and gyration in, realize the radial feed of main shaft slide plate.
The utility model is not limited to the foregoing description, and according to the description of the foregoing description, those of ordinary skill in the art also can make some conspicuous changes, but these changes all should fall within the protection domain of the utility model claim.
