Abstract
A triangular pyramid machine tool spindle is characterized by comprising a knife handle, a disc knife and a fixed disc. The disc knife is fixed to the periphery of the fixed disc. The fixed disc is fixedly installed at one end of the knife handle. The knife handle is of a hollow short cone structure which is in a triangular pyramid shape, the edges of the structure are in a circular arc shape, and the taper of the structure is 1/20. The disc knife is fixedly installed at the end, with the large sectional area, of the knife handle. The knife handle is fixedly installed in a transmission shaft internally provided with the triangular pyramid shape. The transmission shaft is connected with a motor. The triangular pyramid machine tool spindle is simple in structure and convenient to use, transmission connection between a driving key and a key groove is omitted, the problem of dynamic balance is solved, and machining precision is improved.
Description
Technical field
The utility model relates to triangular pyramid machine tool chief axis, and it is a kind of machine tool chief axis of triangular pyramid shape handle of a knife, belongs to mechanical field.
Background technology
Machine tool chief axis refers to the axle that drives workpiece or cutter rotation on lathe, conventionally by main shaft.Bearing and driving member etc. form spindle unit.In machine, be mainly used to support driving parts as gear, belt wheel, transmit motion and moment of torsion, as machine tool chief axis; What have is used for clamping workpiece, as axle.Most of lathes have spindle unit.The kinematic accuracy of spindle unit and the rigidity of structure are the key factors that determines crudy and stock-removing efficiency.The index of weighing spindle unit performance is mainly running accuracy, rigidity and velocity adaptive.1. running accuracy: beat affecting occur in the direction of machining accuracy radial and axial during main shaft rotation, depend mainly on manufacture and the assembly quality of main shaft and bearing.2. dynamic and static rigidity: depend mainly on the bending stiffness of main shaft, the rigidity of bearing and damping.3. velocity adaptive: the maximum speed of permission and the range of speeds, depend mainly on the structure of bearing and lubricated, and radiating condition.
The handle of a knife of current machine tool chief axis is generally cone shape, by establish driving key or keyway on the surface of handle of a knife, and driving key and keyway engaging, when work, realize transmission, but traditional like this kind of drive can cause dynamic equilibrium problems, cause the precision of processing to be difficult to control.
Summary of the invention
In order to solve the problem of above-mentioned existence, the utility model discloses a kind of triangular pyramid machine tool chief axis, the handle of a knife of triangular pyramid shape, can directly be stuck in the identical driving member of shape, more stable transmission, greatly reduces the dynamic equilibrium problems that traditional driving key and keyway transmission produce.
Triangular pyramid machine tool chief axis, comprises handle of a knife, dise knife and fixed disk, and dise knife is fixed on fixed disk surrounding, and fixed disk is fixed on one end of handle of a knife, and handle of a knife is triangular pyramid shape, and rib is circular shape, the hollow short wimble structure that tapering is 1/20.
Described dise knife is fixed on one end that handle of a knife basal area is large.
Described handle of a knife is fixed in the power transmission shaft that inside is provided with triangular pyramid shape, and power transmission shaft connects motor.
The utility model, dise knife is fixed on one end of handle of a knife, and handle of a knife is installed fixed card in the power transmission shaft of triangular pyramid, by driven by motor power transmission shaft, rotated, drive handle of a knife rotation, in drive process, can effectively avoid dynamic balancing, machining accuracy is higher, the longer service life of handle of a knife.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
Fig. 2 be the A of Fig. 1 to view,
Reference numerals list: 1-handle of a knife, 2-fixed disk, 3-dise knife.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.Should understand the following specific embodiment and only for the utility model is described, be not used in restriction scope of the present utility model.It should be noted that, word 'fornt', 'back', " left side ", " right side ", "up" and "down" that use is described below refer to the direction in accompanying drawing, and word " interior " and " outward " refer to respectively the direction towards or away from specific features geometric center.
Visible by reference to the accompanying drawings, this triangular pyramid machine tool chief axis, comprises handle of a knife 1, dise knife 3 and fixed disk 2, dise knife 3 is fixed on fixed disk 2 surroundings, and fixed disk 2 is fixed on one end of handle of a knife 1, and handle of a knife 1 is triangular pyramid shape, rib is circular shape, the hollow short wimble structure that tapering is 1/20.The utility model, the handle of a knife 1 of triangular pyramid shape is conducive to handle of a knife 1 fixed installation, and when operation, can not produce dynamic balancing, and machining accuracy is higher, and rib is that circular shape can be avoided corner angle wearing and tearing, also avoids corner angle to hurt sb.'s feelings.
Described dise knife 3 is fixed on the large one end of handle of a knife 1 basal area.Dise knife 3 is arranged on the large one end of handle of a knife 1 basal area, and motor gives power from the little one end of handle of a knife 1 basal area, makes handle of a knife 1 rotation, and power can evenly pass to dise knife 3, and surrounding is stressed evenly.
Described handle of a knife 1 is fixed in the power transmission shaft that inside is provided with triangular pyramid shape, and power transmission shaft connects motor.The main shaft of triangular pyramid shape is inserted in power transmission shaft inside, fixing-stable.
The disclosed technological means of the utility model scheme is not limited only to the disclosed technological means of above-mentioned technological means, also comprises the technical scheme being comprised of above technical characterictic.
