Description

Asynchronous drilling machine

Technical field

The utility model relates to a kind of asynchronous drilling machine, belongs to the Machining Technology field.

Background technology

Asynchronous drilling machine, the in the same way axle of installing on the finger board, when the same operating instruction that receives that controller sends, can not process simultaneously between the axle in the same way, same motion life period is poor, and can process according to the axle order of autonomous selection man-hour adding, perhaps cancel respective shaft.

Continuous progress along with science and technology, the circuit board product required precision is strict all the more, in order to answer above-mentioned circuit board product quality requirements, must when cutting, reduce as far as possible circuit boring the vibration of board, reduce the active force that the board transmission produces, foregoing circuit plate procedure, circuit board is positioned on the workbench, by drilling tool the circuit board that is positioned over above the workbench is holed, because workbench and sliding stand are as a whole, its motion time is not by a large motor driving, the instantaneous acceleration ratio of board is larger, this method of operation is because the weight of whole workbench is larger, the active force that motor produces will be large, and it moves relative can compare large of inertia that lock produces when stopping in moment, and the vibration meeting that produces when transmission is larger, board workpiece in this situation does not reach required precision because the vibration of board causes greatly also can becoming greatly in the trueness error that adds the appearance in man-hour.

The utility model content

Purpose: in order to overcome the deficiencies in the prior art, the utility model provides a kind of asynchronous drilling machine.

Technical scheme: for solving the problems of the technologies described above, the technical solution adopted in the utility model is:

As preferred version, described Y workbench is three, and the X sliding stand is three, and the Z sliding stand is six.

Beneficial effect: the asynchronous drilling machine that the utility model provides, prevent that board from producing covibration when operation, reduced the load of each motor in the running, reduce its buffering, improved the speed of service of board, active force when reducing simultaneously the board transmission reduces the vibration of board and reduces the active force that motor drives, and guarantees the machining accuracy of board.

Description of drawings

Fig. 1 is structural representation of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

As shown in Figure 1, a kind of asynchronous drilling machine comprises slide track seat 1,5, three pairs of Y linear slide rails 7 of 4, six Z sliding stands of 3, three X sliding stands of 2, three Y workbench of crane span structure, a pair of x-ray slide rail 8, and a plurality of drive unit;

Crane span structure 2 vertically is installed on the slide track seat 1, and slide track seat 1 forms X-Y plane, and crane span structure 2 forms the X-Z face; The three pairs of Y linear slide rails 7 X-Y plane along Y direction parallel being fixed on the slide track seat 1, each Y workbench 3 is slidingly connected and is arranged on a pair of Y linear slide rail 7; A pair of x-ray slide rail 8 the X-Z face along X-direction parallel being fixed on the crane span structure 2, three X sliding stands 4 are slidingly connected and are arranged on the x-ray slide rail 7, Z-direction is provided with two Z sliding stands 5 on each X sliding stand 4, be provided with one drilling equipment on each Z sliding stand 5, can move up and down workpiece is holed;
