Abstract

The utility model discloses an automatic sharpening machine for spline broaches, which comprises a main platform. A headstock box and a retractable tailstock center are respectively arranged at the left end and the right end of the main platform, a headstock center matching with the tailstock center is rotationally mounted in the headstock box, a spline broach is mounted between the headstock center and the retractable tailstock center, and a machine base box is disposed below the main platform. The automatic sharpening machine is characterized in that a Z-direction linear guide rail and sliding plate system capable of moving left and right is disposed on the main platform, an X-direction linear guide rail and sliding plate system capable of moving back and forth is mounted on a sliding plate of the Z-direction linear guide rail and sliding plate system, and an electric grinding head is mounted on a sliding plate of the X-direction linear guide rail and sliding plate system. By the aid of the automatic sharpening machine, the sharpening position of the broach is adjusted automatically, sharpening precision is guaranteed, the service life of the broach is prolonged greatly, labor intensity of operators is also reduced, and efficiency is enhanced.

Description

Spline broach automatic sharpening lathe
Technical field
The utility model relates to a kind of grinding machine, mainly is a kind of spline broach automatic sharpening lathe.
Background technology
Existing spline broach is by the Artificial Control sharpening, thereby causes the cutting teeth tooth portion amount of increasing not wait easily, easily accelerated wear test broaching tool cutter tooth, cause phenomenons such as broken teeth, broaching tool fracture even; Reduced the service life of broaching tool; For this reason, often change broaching tool, and this has increased cost.Strengthen labor intensity of operating staff, caused production efficiency low.
The utility model content
The utility model technical problem to be solved provides a kind of automatic sharpening lathe of spline broach; It adopts sliding straight guide rail sledge system, ball screw, servo-control system and high-precision digital control system to regulate the sharpening position of broaching tool automatically; Guarantee the precision of sharpening; Thereby effectively guaranteed the uniformity of the work broaching tooth tooth portion amount of increasing, improved and prolonged the service life of broaching tool greatly, reduced production cost.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is
A kind of spline broach automatic sharpening lathe; Include main platform; The left and right two ends of main platform are respectively equipped with headstock case, telescopic tail centre, are rotatablely equipped with the crown point that cooperates with tail centre in the headstock case, between crown point and the telescopic tail centre spline broach are installed; Main platform below is provided with the lathe base case; It is characterized in that: but described main platform is provided with the line slideway sledge system of the Z direction of move left and right, and the directions X line slideway sledge system that can move forward and backward is installed on the slide plate of the line slideway sledge system of Z direction, on the slide plate of directions X line slideway sledge system the electric mill head is installed.
The line slideway sledge system of described X, Z direction includes by being made up of screw mandrel, slide rail and the slide plate of driven by servomotor respectively; A side also is provided with electric cabinet on the described main platform, and the servomotor of the line slideway sledge system of X, Z direction all inserts electric cabinet; Described electric mill head is made up of motor, the emery wheel that is installed on the motor shaft.
Circuit in the utility model all is connected in the circuit control box, can be through the guidance panel operation.
Operating procedure in the utility model: several kinds of parameters of input broaching tool get into computer numerical controlled system; At first through X axis, Z is axial, operates the starting point tool setting with the cutter of being processed, and behind good datum mark, makes grinding head grinding wheel break away from the broaching tool workpiece along X axis, carries out an idle stroke running, verifies the correctness of each parameter, just can carry out sharpening processing after accurate.
Operation is X axis fast turn-around in proper order, makes grinding head grinding wheel march to broaching tool and wants footpath at the bottom of the cutter tooth of grinding, carries out grinding work, then rollback fast.Z axially is programmed into to a tooth pitch by system and leaves, and X axis is fast turn-around once more, makes grinding head grinding wheel march to second cutter tooth that broaching tool is wanted grinding.Reciprocation cycle is returned initial point to last tooth grinding completion, accomplishes grinding circulation; Finely tune then Z axle feeding size (each 0.02mm ~ 0.04mm), carry out the grinding second time, to cutting teeth grind fully sharp till.
The utility model adopts sliding straight guide rail sledge system, ball screw, servo-control system and high-precision digital control system to regulate the sharpening position of broaching tool automatically.
The utility model has the advantages that:
The utility model can be regulated the sharpening position of broaching tool automatically, guarantees the precision of sharpening, improves and prolonged the service life of broaching tool greatly, has also alleviated operative employee's labour intensity, and efficient is improved.
Description of drawings
Fig. 1 is the front view of the utility model.
Fig. 2 is the side view of the utility model.
The specific embodiment
Referring to Fig. 1; Spline broach automatic sharpening lathe includes main platform 1, and main platform 1 left and right two ends are respectively equipped with headstock case 2, telescopic tail centre 3; Be rotatablely equipped with the crown point 4 that cooperates with tail centre 3 in the headstock case 2; Between crown point 4 and the telescopic tail centre 3 spline broach 5 is installed, main platform 1 below is provided with lathe base case 6, but main platform 1 is provided with the line slideway sledge system 7 of the Z direction of move left and right; The directions X line slideway sledge system 9 that can move forward and backward is installed on the slide plate 8 of the line slideway sledge system 7 of Z direction, on the slide plate 10 of directions X line slideway sledge system 9 electric mill head 11 is installed.Electric mill head 11 is made up of motor, the emery wheel 12 that is installed on the motor shaft.Described electric mill head 11 tops are equipped with dresser, during elongated broaching tool sharpening, need increase by two bracing frames 13,14 in the centre, prevent flexural deformation.The servomotor of the line slideway sledge system of X, Z direction all inserts electric cabinet 15.The line slideway sledge system of X, Z direction includes by the screw mandrel, slide rail and the slide plate that are driven by servomotor 16 respectively to be formed.
