Description
Technical Field
The utility model relates to a mining motor field specifically says so a reduce processingequipment of motor harmonic.
Background
The spiral key groove on the rotor shaft is one of effective modes for reducing the harmonic waves of the motor, and the effect is very obvious. But the common processing is time-consuming and labor-consuming, and large errors are easy to generate. If the spiral key groove is not processed, the remarkable effect cannot be achieved, and meanwhile, the spiral key groove is processed, so that the requirement on the operation degree of workers is high.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model discloses a muddy water automatic alarm flashboard.
The specific technical scheme is as follows:
a machining structure of a motor shaft spiral key groove milling tire comprises a base, wherein a guide rail is arranged inside the base, a gear shaft is arranged on a guide seat abutted to the guide rail inside the base, the gear shaft is coupled to the center of the guide seat, the gear shaft is fixedly connected with a main shaft, a rack arranged below the gear shaft is meshed with a gear of the gear shaft, the rack is connected with a guide block, the guide block is sleeved at the lower end of the rack, a lead screw is arranged below the guide block, the lead screw is connected with a threaded hole at the lower end of the guide block, and the lead screw drives the guide block to move; the end part of the screw rod is also connected with the inclined guide rail, and a transverse wheel arranged at the end part of the rack is connected with the inclined guide rail in a sliding manner; one end of a workpiece arranged on the base is connected with the main shaft, the other end of the workpiece is connected with the tailstock, and the milling cutter is right opposite to one end of the workpiece.
And a ball is arranged between the guide block and the rack, the lower end of the guide block moves on the screw rod back and forth, and the upper end of the guide block moves on the rack through the idler wheel.
The lead screw and the rack are arranged perpendicularly to each other.
The guide seat is connected with the guide rail inside the base in a sliding mode through the idler wheels.
The utility model has the advantages that: the rigidity during processing can be improved, the effectiveness of a processed part is ensured, the previous process of processing and marking is omitted, and the production efficiency is further improved; the clamping fixture does not need to change a vertical milling or horizontal milling structure, does not influence the use of a standard milling cutter fixture when used in vertical milling or horizontal milling, is very convenient for tool changing and operation, and does not need to align the inclination according to a line.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a view of FIGS. 1A-A;
Detailed Description
The utility model is described in detail with reference to the accompanying drawings, as shown in fig. 1 and fig. 2, a processing structure of motor shaft spiral keyway milling tire comprises a base 1, a guide rail 101 is arranged inside the base 1, a gear shaft 3 is arranged on a guide base 2 abutted to the guide rail inside the base 1, the gear shaft 3 is coupled at the center of the guide base 2, the gear shaft 3 is fixedly connected with a main shaft 4, a rack 5 arranged below the gear shaft 3 is meshed with a gear of the gear shaft 3, the rack 5 is connected with a guide block 6, the guide block 6 is sleeved at the lower end of the rack 5, a lead screw 7 is arranged below the guide block 6, the lead screw 7 is connected with a threaded hole 601 at the lower end of the guide block 6, and the lead screw 7 drives the guide block 6 to move; the end part of the screw rod 7 is also connected with an inclined guide rail 8, and a transverse wheel 9 arranged at the end part of the rack is connected with the inclined guide rail 8 in a sliding way; one end of a workpiece 10 arranged on the base 1 is connected with the spindle 4, the other end is connected with the tailstock 11, and the milling cutter 14 is opposite to one end of the workpiece 10.
And a ball 12 is arranged between the guide block 6 and the rack 5, the lower end of the guide block 6 moves back and forth on the screw 7, and the upper end of the guide block 6 moves on the rack 5 through a roller 12.
The lead screw 7 and the rack 5 are arranged perpendicular to each other.
The guide seat 2 is connected with the guide rail inside the base 1 in a sliding way through a roller 13.
The utility model discloses a theory of operation is: the lead screw drives the guide block to move, and meanwhile, as the guide block on the lead screw is in sliding connection with the rack, the guide block generates a force for the rack to move on the inclined guide rail; the inclined guide rail enables the rack and the gear shaft to rotate in a matched mode due to the appearance structure, the gear shaft rotates to drive the main shaft to rotate, the workpiece rotates, and the milling cutter only needs to move linearly from one end of the workpiece to the other end of the workpiece.
