The utility model content
The utility model is for solving problems such as existing member drilling clamp mechanism complex operation, clamping positioning accuracy are low, provide the active clamp mechanism based on the non-magnetic connection part drilling of magnechuck that has that opening character is good, easy and simple to handle, precision is high, efficient is high.The utility model has following technical scheme:
A kind of active clamp mechanism of non-magnetic connection part drilling is characterized in that: comprise that the upper end has the matrix of magnetic core mounting groove, is installed on H shape magnetic core in the magnetic core mounting groove, is around in coil on the H shape core center beam, is installed on the end cap of matrix upper end; Above-mentioned end cap is made up of horizontal panel and the panel magnetic pole that is positioned at the horizontal panel left and right sides jointly, and about two panel magnetic poles just in time be positioned at H shape magnetic core about two lateral beams tops, above-mentioned horizontal panel central authorities also stud with at a distance from magnet; The panel magnetic pole of the above-mentioned end cap left and right sides is higher than the height of horizontal panel, makes the horizontal panel top form the workpiece clamping slot; Cushion block and workpiece in groups are housed in the above-mentioned workpiece clamping slot from bottom to top, in the workpiece clamping slot, are positioned at workpiece side installing and locating block, the irony press strip is placed in the end cap top; Above-mentioned irony press strip is adsorbed on the panel magnetic pole under the attraction of coil electricity generation suction, plays the effect of clamping work pieces.
Above-mentioned panel pole edge is higher than mid portion, and middle groove part is used for installing cushion block and clamping workpiece in groups, and the raised area plays Y to positioning action.Cushion block is mainly used in and guarantees the workpiece planarization positioning accuracy in groups, and can play supporting workpiece to increase the effect of its rigidity and protection panel.Compare with traditional magnechuck, this clamp mechanism can be carried out clamping and location to non-magnetic workpiece, and does not worry that non-magnetic workpiece blocks the magnetic circuit circulation of magnechuck.This clamp mechanism has convenient, the convenient disassembly of adjustment, safe and reliable advantage, has avoided complicated clamping operation, has improved the precision and the efficient of drilling.
For avoiding occurring the leakage field phenomenon between magnetic core and matrix, stud with at a distance from magnet in four sides in bottom surface and front, rear, left and right of above-mentioned H shape magnetic core.
Safe in utilization for guaranteeing the related clamp mechanism of the utility model, be convenient to cabling, matrix inside is provided with cable tray; For making things convenient for clamping workpiece, the clamps groove is left in the adjacent both sides of matrix in addition.
The utility model adopts the new wound-rotor mode, realizes non-magnetic connection part quick-clamping, location and dismounting; Adopt cushion block in groups, realize the rapid adjustment of mechanism and protect in the drilling operation process cutter and anchor clamps not to be damaged.This clamp mechanism is simple in structure, compact, and it is convenient to adjust, and convenient disassembly can satisfy the requirement of accurate, the efficient clamping of non-magnetic connection part drilling in the aircraft assembling.

Label title among the figure: 1, matrix, 2, H shape magnetic core, 3, the panel magnetic pole, 4, horizontal panel, 5, at a distance from magnet; 6, coil, 7, workpiece, 8, the irony press strip, 9, the workpiece cushion block; 10, position block, 11, dotted line is magnetic induction line, 12, the workpiece clamping slot, 13, the magnetic core mounting groove.
The specific embodiment
Below in conjunction with Figure of description, tell about the initiatively embodiment of clamp mechanism of the utility model non-magnetic connection part drilling.Like Fig. 1, shown in Figure 2, this mechanism mainly comprises matrix 1, H shape magnetic core 2, panel magnetic pole 3, horizontal panel 4, at a distance from magnet 5, coil 6, irony press strip 8, cushion block 9, position block 10 in groups.H shape magnetic core 2 is installed in the matrix 1; Coil 6 is around the intermediate groove place of H shape magnetic core 2, and energising produces magnetic induction line then and passes magnetic core the first half, magnetic pole 3 and irony press strip 8 formation magnetic circuits; End cap and matrix 1 usefulness attachment screw are fastening; Cushion block 9 usefulness attachment screws are fastened on the end cap in groups; Irony press strip 8 is adsorbed on the panel magnetic pole 3 of end cap under the attraction of coil 6 energising generation suction, plays the effect of clamping work pieces 7.As shown in Figure 3, position block is connected on the matrix 1, plays location workpiece effect.
Described matrix 1 side has holddown groove and winding wiring hole; Four sides in H shape magnetic core 2 bottom surfaces and front, rear, left and right stud with at a distance from magnet; The two ends magnetic pole of horizontal panel 4 exceeds mid portion, and mid portion studs with panel at a distance from magnet 5; Have cross deep gouge screw hole in groups on the cushion block; Have the eccentric screw hole on the position block.
The course of work of the utility model is following:
At first, the cushion block in groups 9 that assembles is made Milling Process, make its horizontal accuracy peace surface roughness reach the requirement of drilling processing.Lay workpiece 7 then, and through position block and panel magnetic pole 3 to its do XY to the location, cover irony press strip 8 at last, and connect the clamp mechanism power supply.Coil 6 energising backs produce magnetic induction line, and magnetic induction line passes the first half and the panel magnetic pole 3 of H shape magnetic core 2, gets back to magnetic core through the irony press strip 8 on the workpiece again and forms magnetic circuit, produces suction.Notice that distance between two irony press strips will guarantee the existence in the drilling zone of workpiece; And thickness of workpiece and in groups the height sum of cushion block equal the difference in height of face plate edge and mid portion just; So cushion block can guarantee the smooth processing of workpiece like this along with the difference of thickness of workpiece has the height of a series in groups.
Secondly, workpiece processes the back and cuts off coil power, require clamp mechanism within a certain period of time demagnetization be beneficial to take off (actual is to take off the irony press strip) of workpiece, promptly require to have certain demagnetization cycle.
In order to remove remanent magnetism, can adopt the material of the material of the low constant magnetic conductivity of remanent magnetism as core material and irony press strip; Behind coil electricity, produce magnetization curve and make sucker suck workpiece, when outage back magnetization curve falls after rise,, play demagnetizing action so can block remanent magnetism though there is this moment remanent magnetism very little and owing to sucker has certain working gas gap.
