Description

Separated full-automatic drilling and riveting bracket system

Technical field

The present invention relates to a kind of brill riveting carriage, relate generally to the separated full-automatic drilling and riveting bracket system that is used for thin-walled panel beating zero, parts automatic drill riveting assembling.

Background technology

The automatic rivet bracket system integrates product mechanical, electrical, liquid, motion by digital control system control automatic rivet bracket realize to the thin-walled metal plate parts locate automatically, clamping, normal direction regulate, in conjunction with the automatic drill riveter, realize thin-walled panel beating zero, parts automatic drilling (counter boring), gluing, send nail, mill the equality function.In the prior art, drilling and riveting bracket system mainly contains three kinds of structures: complete soft semi-automatic drilling and riveting bracket system, the semi-rigid automatic carriage of suspension type system, the full rigidity automatic rivet bracket of the stand column fixing system of hanging of suspension type.Respectively there are pluses and minuses in these three kinds of automatic rivet bracket systems: soft to hang semi-automatic drilling and riveting bracket system structure simple, cheap though suspension type is complete, can't realize accurately location and automatic drill riveting; The semi-rigid automatic carriage of suspension type system location is more accurate, but rigidity and less stable can only realize automatic drill riveting in the single stringer, stride stringer and bore manually adjustment of riveting, can only realize semi-automatic brill riveting, the riveting work continuity is relatively poor, production efficiency is low, and the Installation and Debugging difficulty; The full rigidity automatic rivet bracket of stand column fixing system mainly is made up of the fixed column in the left and right sides, holder frame, X slide unit, Y slide unit, driving mechanism, control system etc., can realize numerical control accurately location and automatic drill riveting, cause X-axis slide unit centre-of gravity shift but the monoblock type y-axis shift is moving, cause stabilization of equipment performance poor.Simultaneously, equipment and basic floor space are big, because the structural limitations of X-axis, Y-axis slide unit causes the product clamping to be adjusted and maintenance operation inconvenience.

Summary of the invention

The objective of the invention is provides a kind of numerical control accurately to locate at above-mentioned the deficiencies in the prior art part, and the automatic drill riveting is reliable and stable, floor space is little, the separated full-automatic drilling and riveting bracket system of convenient operating maintenance.

In order to achieve the above object, the invention provides a kind of separated full-automatic drilling and riveting bracket system, comprise: horizontal X-axis guide rail and the X slide unit that on the X-axis guide rail, moves, be installed in boring and riveting machine and operating desk on the X slide unit, the Y-axis guide rail reaches the left and right sides Y slide unit that moves on the Y-axis guide rail longitudinally, be installed in the column on the Y slide unit of the left and right sides, be installed in the Z slide unit on the column, be installed in the holder frame on the Z slide unit and drive the driving mechanism that the holder frame rotates, be fixed on holder be used for fixing on the frame and locate thin-walled panel beating parts process box etc., boring and riveting machine and holder frame are along X-axis, Y-axis is separated self-movement, boring and riveting machine integral body moves laterally (X-axis), column and be installed in holder frame vertical with the direction of motion of boring and riveting machine (Y-axis) on the column; The driving mechanism that holder frame and driving holder frame rotate is installed on the Z slide unit, and two driven by servomotor Z slide units in column upper end and the lifting of drive holder frame realize the motion of Z axle;

Two driven by servomotor holder frames on the Z slide unit rotate, and form the motion of A axle; Move by the differential realization of Z1, Z2 B axle; Move by the differential realization of Y1, Y2 C axle.Realize thin-walled panel beating zero, positioning parts and normal direction adjustment by the associated movement of X, Y, Z, A, B, six reference axis of C, and in conjunction with the automatic drill riveter finish thin-walled panel beating zero, parts automatic drilling (counter boring), gluing, send nail, mill the equality function.

On the holder frame, be provided with and install and the location benchmark, and at different Element Designs special-purpose process box, process box is fixed on the holder frame by installation on the holder frame and location benchmark, thin-walled panel beating zero, parts are installed on the process box, the shared same holder frame of different process boxs is realized the production to different thin-walled panel beatings zero, parts on same rack system.

The present invention has following beneficial effect than prior art:.

1) the present invention adopts boring and riveting machine and carriage along X, Y-axis disengaging movement formula structure, and is simple in structure.Because boring and riveting machine only moves along X-axis, fixed-site along Y-axis, therefore, X-axis drives the center can be fixed in X slide unit position of centre of gravity, solve the full rigidity automatic rivet bracket of stand column fixing system and when y-axis shift moves, caused boring and riveting machine centre-of gravity shift problem, can guarantee that boring and riveting machine drives the constant of load along X-axis, stabilization of equipment performance is good, the positioning accuracy height.

2) owing to adopt X, Y-axis disengaging movement formula structure, boring and riveting machine does not move along the position of Y-axis, system compares with the full rigidity automatic rivet bracket of stand column fixing, cancelled and be used to install the Y of boring and riveting machine to slide unit, reduced the boring and riveting machine setting height(from bottom), thereby the holder frame that thin-walled panel beating zero, parts are installed can be separated with boring and riveting machine, and will ask frame to drop to apart from the lower height in ground (below 1.5 meters), operation is very easy when clamping, adjustment product.

3) owing to adopt full rigid structure, by driven by servomotor holder frame rotation (A axle), and adopt full cut-off ring control mode, the location accurately, can realize striding the riveting of stringer automatic drill, the production continuity is good, the automaticity height, the working (machining) efficiency height, riveting quality is stable, and working (machining) efficiency belongs to advanced international standard.

Because adopt X, Y-axis disengaging movement formula structure, floor space is less relatively relative with area of base less, save the factory building space; The manufacturing cost of carriage is lower, and its total cost is than the equipment less than 2/3 that possesses said function abroad.
