Technical field

The utility model belongs to the Machining Technology field, relates to the work holder of the work holder on a kind of milling device, particularly a kind of automatic slot milling machine.

Background technology

At mechanical processing industry, to the groove of some path shaft end or flat add man-hour, adopt slotter to carry out milling usually, add and man-hour workpiece is fixed to clamp on workbench, by milling cutter Milling Process is carried out in the end of workpiece.In the process, most important to the clamping and positioning of workpiece to be processed, the stability that workpiece clamps is the quality of influence processing directly.Existing anchor clamps adopt special fixture mostly, and cost is very high; Many technology personnel also attempt the special fixture of simplicity of design practicality, but all unsatisfactory.

As a kind of polyhedron production miller that Chinese patent provided, its publication number is " CN2894905 ", and this milling machine is based on two milling heads, and the shop is with relevant support component, and hydraulic pressure is electric, digital control system and miscellaneous part constitute two-sided to milling; Carry out semi-automatic cyclic process, i.e. people's frock workpiece, hydraulic clamp locking, numerical control scale-division, milling cutter rotates, and hydraulic pressure moving platform drives part to be processed F.F. and workpiece feeding; After machining, hydraulic pressure unclamps part automatically, manually unloads part, is suitable for processing the technological requirement that the path axle carries out groove milling.

" special-purpose ' V ' type slotter " that and for example Chinese patent provided, its publication number is " CN101239404A ", it comprises frame, frame is provided with workbench, on workbench, be provided with slotting attachment and clamping device, clamping device comprises compressed oil cylinder and pressure strip matching used with it, and pressure strip is installed in the bottom of compressed oil cylinder.

As can be seen, above-mentioned these two kinds of milling devices all are to adopt hydraulic pressure or pneumatic mode as clamping power when workpiece is clamped, and structure all more complicated and energy resource consumption is big, has improved production cost indirectly.

The utility model content

The objective of the invention is at the existing the problems referred to above of existing slotter, and it is little to have proposed a kind of energy resource consumption, the work holder of automatic slot milling machine simple in structure.

The purpose of this utility model can realize by following technical proposal: a kind of work holder of automatic slot milling machine, be arranged on along on the sliding platform of guide rail slip, comprise and be used to place the clamping plate of workpiece to be processed and the clamping structure that workpiece is clamped, have chute on the clamping plate, it is characterized in that, described clamping structure comprises slide bar and actuating unit, slide bar is connected with actuating unit, above-mentioned slide bar is equipped with in chute and can drives the lower edge chute at actuating unit and moves back and forth, and forms the baseline trough of placing workpiece to be processed between the end of slide bar and the chute end.

Slide bar can be free to slide in chute, and the space between the end of slide bar and the chute end is the baseline trough that is used to place workpiece to be processed, and the size of baseline trough changes with the slip of slide bar.The size of baseline trough is greater than the size of workpiece to be processed before the processing, and after workpiece was placed in the baseline trough, actuating unit drove chute to the motion of workpiece direction, and baseline trough diminishes, and then workpiece is clamped.

In the work holder of above-mentioned automatic slot milling machine, described actuating unit comprises the shaft-like swing component hinged with slide bar, one end of swing component is provided with roller, the other end and above-mentioned clamping plate are rotationally connected, be provided with spring between pin joint on the swing component and the roller, the two ends of spring act on respectively on clamping plate and the swing component, and guide rail is provided with fixed block, and fixed block also is provided with the planing surface that swing component compresses spring when roller passes through fixed block towards a side of roller.

Swing component is connected with clamping plate with slide bar, can be with clamping plate along guide rail movement.When clamping plate during towards the motion of the milling direction of guide rail, roller rolls along planing surface, this moment, swing component was that swing to the slide bar direction in the center of circle with the tie point that is rotationally connected with clamping plate, spring is compressed, simultaneously by acting on slide bar with the hinged pin joint of slide bar, slide bar is promoted toward chute is inboard, dwindle baseline trough, clamping work pieces.After the clamping, keep the compression degree of clamping dynamics and spring constant, finish up to milling work.

In the work holder of above-mentioned automatic slot milling machine, the inner wall shape of described baseline trough and the outer surface of processing work are complementary.Shape is complementary to increase the stability that workpiece clamps, and helps improving crudy.

In the work holder of above-mentioned automatic slot milling machine, described planing surface comprises the ascent stage and the parallel-segment parallel with guide rail that moves closer to clamping plate along the clamping plate direction of motion, and the top of described ascent stage is connected with parallel-segment.Roller is along in the ascent stage rolling process, and swing component promotes slide bar workpiece is clamped to the swing of slide bar direction.Finish clamping work when roller enters parallel-segment, workpiece enters the milling stage, and this moment, the clamping dynamics of workpiece remained unchanged.

In the work holder of above-mentioned automatic slot milling machine, be fixed with the adjusting rod of adjusting the baseline trough minimum dimension on the described clamping plate, above-mentioned swing component is socketed on the adjusting rod, and the both sides that are positioned at the swing component tie point on the adjusting rod are respectively equipped with resetting-mechanism and the nut that has been threaded.

According to the size of workpiece to be processed, adjust the size of baseline trough when being in clamped condition.Link position along adjusting rod rotation threaded adjustment swing component changes the angle that swing component can be swung with this, and resetting-mechanism is compressed in the adjustment process.

In the work holder of above-mentioned automatic slot milling machine, described resetting-mechanism is back-moving spring and fixture block, and fixture block and adjusting rod are connected, and the two ends of above-mentioned back-moving spring act on respectively on fixture block and the swing component.When nut rotated to the back-moving spring direction, back-moving spring was compressed.

Compared with prior art, the work holder of this automatic slot milling machine is after the washing trough machine is started working, and roller makes swing component produce swing along having in the planing surface sliding process of high low head, and then forms the thrust to slide bar.Whole process relies on the power resources of the power that relative motion produced of sliding platform and guide rail as clamping work pieces, and does not need special power-equipment that workpiece is clamped, and energy resource consumption is low, has reduced production cost.Along in the guide rail movement process, finish clamping and milling work at sliding platform successively, be connected compactness, greatly system production efficiency.The inner wall shape of baseline trough and the outer surface of processing work are complementary, and make that clamping is more firm, and crudy is guaranteed.
