Description
Technical field
The utility model relates to a kind of gear shapping machine of Gear Processing, especially a kind of last pulling apparatus of gear shapping machine cutter shaft.
Background technology
Gear shapping machine is a machining equipment common in the Gear Processing, and most of gear shapping machine does not possess and lifts function on the cutter shaft.Therefore the range of work is little, occurs the gear shapping machine that some lift function on possessing at present, and its structure is: increase by a cover hydraulic jack mechanism in the column side, is connected with the gear shaping cutter shaft, gear shapping machine adds pin, the pin-and-hole pinning that man-hour, hydraulic jack mechanism was hydraulically controlled.When lifting function on needing, pin withdraws from pin-and-hole, and the piston of hydraulic jack mechanism is promoted by hydraulic oil, drives the cutter shaft action, makes on the cutter shaft and carries.Carry in the cutter shaft action finish after, pin enters pin-and-hole by hydraulic control, hydraulic jack mechanism is lockable again.Though this mechanism can realize cutter shaft on lift function, but after fabrication cycles is finished each time, all will unclamp locking once, operation can make pin or pin-and-hole produce plastic deformation so continually, make hydraulic jack mechanism produce play, directly influence the machining accuracy of gear shapping machine.
Summary of the invention
The utility model provides a kind of last pulling apparatus of easy and simple to handle, gear shapping machine cutter shaft that precision is high for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of last pulling apparatus of gear shapping machine cutter shaft, column by gear shapping machine, be installed in slide plate moving up and down on the column, be installed in knife rest and cutter relieving and main drive on the slide plate, and the slide plate locking device that is installed on the column is formed, described locking device be in slide plate both sides and column both sides respectively correspondence operating slide guideway rail and column guide rail are installed, the pressing plate of operating slide guideway rail also is installed in the column both sides, the inboard, bottom surface of pressing plate is shaped on the rectangular channel with the operating slide guideway rail coupling, the outside, bottom surface of pressing plate is shaped on several grooves, corresponding each groove such as is separately installed with at the oil cylinder of quantity on pressing plate, the piston rod of oil cylinder is shaped on centre bore, the bolt that connects column is installed in the centre bore of piston rod, the dish spring that compresses the operating slide guideway rail pressing plate is installed in the plunger shaft of oil cylinder inboard, and the plunger shaft in the oil cylinder outside is connected with the high-pressure oil pipe that loosens the operating slide guideway rail pressing plate; Described slide plate trailing flank is equipped with screw and the leading screw that lifts, and is equipped with in the upper end of column to drive the servomotor that leading screw rotates, and the balancing cylinder of slide plate weight also is installed between the upper end of column and slide plate.
Advantage and the good effect that the utlity model has are: because the spring bearer plate that slide plate locking and the bottom surface of loosening is had several grooves is installed in the column both sides, respective slot is installed several control oil cylinders on pressing plate, and be used for leading screw, screw that lifts and the balancing cylinder that is used for gravitational equilibrium what driven by servomotor was installed between slide plate and the column, therefore can solve the problem that lifts on the slide plate and lock by the operation that lifts and lock on the gear shapping machine operating desk control cutter shaft; Little distortion that a plurality of in addition oil cylinders are controlled pressing plate on a large scale compresses whole slide plate, has eliminated the slide plate play, has improved positioning accuracy; That the utility model also has is simple in structure, reliable in action, advantage that efficient is high.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the A-A cutaway view of Fig. 1.

The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
As shown in Figure 1-Figure 3, the front end of gear shapping machine column 1 is equipped with slide plate 2 moving up and down, is separately installed with knife rest 7 and cutter relieving 13 in the lower end and the side of slide plate, at the trailing flank of slide plate main drive 6 is installed.In order to lift slide plate, at the slide plate trailing flank screw 5 and ball-screw 4 thereof are installed also, be equipped with in the upper end of column and drive the servomotor 12 that leading screw rotates.For balance slide plate own wt, the balancing cylinder 3 of slide plate weight also is installed between column upper end and slide plate, can alleviate the load of ball-screw like this.For the lock slide operating position, at corresponding respectively operating slide guideway rail 15 and the column guide rail 14 that coupling is installed in slide plate both sides and column both sides, the pressing plate 8 that the control operating slide guideway rail moves also is installed in the column both sides, inboard, two pressing plate bottom surfaces is shaped on the rectangular groove of section with the operating slide guideway rail coupling, the outside, each pressing plate bottom surface also is shaped on four grooves 9, and the respective slot position such as is separately installed with at the oil cylinder 10 of quantity on pressing plate.The piston rod of oil cylinder and piston 11 are shaped on centre bore, the bolt that connects column is installed in the centre bore, the dish spring 16 that compresses the operating slide guideway rail pressing plate is installed in the plunger shaft of oil cylinder inboard, the plunger shaft in the oil cylinder outside connects the high-pressure oil pipe that loosens the operating slide guideway rail pressing plate, the dish spring acts on pressing plate when normality like this, makes the pressing plate distortion, clamps operating slide guideway rail and slide plate thereof; When the plunger shaft in the oil cylinder outside was injected hydraulic oil, the dish spring was compressed, and eliminates the active force to pressing plate, and the pressing plate distortion is disappeared (resiling), by the driven by servomotor ball-screw slide plate was moved, thus realize gear shapping machine on lift function.
