Description

Numerical control drilling and milling workpiece rotating clamp

Technical Field

The utility model relates to a field, concretely relates to numerical control bores and mills work piece rotary fixture.

Background

The numerical control machine tool is an indispensable tool for modern industrial production, however, some parts in the existing part machining need to machine various surfaces, such as an axial hole, an inclined hole and an axial key groove. The prior art is to process by three processes respectively. However, the method has the disadvantages of more input equipment, large occupied working area, more labor demand, low working efficiency, poor working quality and incapability of improving the automation degree.

SUMMERY OF THE UTILITY MODEL

For the not enough problem that exists more than solving, the utility model provides a numerical control bores and mills work piece rotary fixture.

The technical scheme is as follows:

the utility model provides a numerical control bores and mills work piece rotary fixture, includes work platform, its characterized in that, the operation platform top is equipped with revolving tool rest and rotatory tool bit, revolving tool rest is including the knife rest bent axle, the revolving tool rest middle part is located to the knife rest bent axle, knife rest bent axle end has servo motor through knife rest bent axle connection, the knife rest bent axle is equipped with positioning clamp one, rotational positioning round pin, locating piece anchor clamps and positioning clamp two by front end to end in proper order.

As a further explanation, a plurality of eccentric wheel radial holes are arranged among the first positioning clamp, the rotary positioning pin, the positioning block clamp and the second positioning clamp.

The utility model discloses possess beneficial effect as follows:

one end of the clamp is provided with a controllable numerical control servo motor, a plurality of surfaces with different angles can be processed on the same station, the workpiece needs 2 radial holes of the eccentric wheel processed by 0 degree of phase, 2 radial holes of the eccentric wheel processed by 180 degrees of phase, 1 radial hole of the main shaft and 1 axial key processed by-15 degrees of phase, the traditional process needs 3 stations for processing, the servo motor is rotated, the numerical control movement of the plane coordinate of the workbench and the automatic numerical control tool changing of the power head are combined, the up-and-down movement is combined to process and combine 6 stations on 1 station, the equipment investment is reduced, the floor area is reduced, the number of manual operations is reduced, the efficiency is provided, the processing quality is improved, and the automation degree is improved.

Detailed Description

The technical solution of the present invention will be clearly and completely described with reference to the accompanying drawings.

As shown in fig. 1-5, a numerical control drilling and milling work piece rotary fixture comprises a working platform and is characterized in that a rotary tool rest and a rotary tool bit 7 are arranged above the working platform, the rotary tool rest comprises a tool rest crankshaft 1, the tool rest crankshaft 1 is arranged in the middle of the rotary tool rest, the tail end of the tool rest crankshaft is connected with a servo motor 5 through the tool rest crankshaft, and the tool rest crankshaft is sequentially provided with a positioning clamp one 2, a rotary positioning pin 6, a positioning block fixture 3 and a positioning clamp two 4 from the front end to the tail end.

And a plurality of eccentric wheel radial holes are formed among the first positioning clamp 2, the rotary positioning pin 6, the positioning block clamp 3 and the second positioning clamp 4.

The product is placed on the clamps 1 and 2, the clamps 1 and 2 are respectively leaned on the positioning block and the positioning pin, then the clamps 1 and 2 are tightly clamped with the product, all radial oil holes in the product are automatically processed after the equipment is started, and the motor drives the clamps to rotate to process the radial oil holes in different directions in the product.

The specific operation flow is as follows:

the power head of the machine tool is a rotary tool rest, the tool can be selected (rotated), fed (moved downwards) and withdrawn (moved upwards) according to a set program, cutting fluid is sprayed and the feeding work is synchronous, 8 rotary tools such as drilling tools, screw taps or milling cutters can be installed on the tool rest, and the tools are installed according to the process requirements; the rotary special fixture is fixed on the workbench, can move in a plane coordinate mode according to a set program or enable the crankshaft to rotate around a main axis, and can realize automatic control positioning and machining by combining with the tool rest to move in a matched mode according to the set program.

The special fixture is designed to move on the plane of the worktable plane (X-Y) according to the program set by the controller, and the crankshaft can rotate around according to the setting of the controller for processing the processing surfaces in different directions.

This process dress 5 cutters, 1 bent axle of special fixture clamping: an eccentric 1 radial oil hole is processed at the A-1 position, and an eccentric 4 oil hole is processed at the A-4 position; after the crankshaft rotates 180 degrees, oil holes of the eccentric wheel 2 are processed at the B-2 position, oil of the eccentric wheel 3 is processed at the B-3 position, and oil holes of the main journal are processed at the B-5 position; and C, machining a short shaft neck key groove 5 x 11 after the crankshaft rotates in the reverse direction by 195 degrees.
