Abstract
The utility model provides an automatic feeding mechanism, which is used for feeding workpieces with central holes into a special fixture of a machine tool and comprises a feeding device for conveying the workpieces to a position for assembling, a swing arm arranged on the machine tool, a motor which is connected with the swing arm and drives the swing arm to swing between a position for taking materials and a position for feeding, a first cylinder for pushing the workpieces to be assembled out of the feeding device, a second cylinder arranged on the swing arm and a clamping mechanism arranged on the swing arm. A piston rod of the second cylinder is matched with the central hole of each workpiece. When the swing arm is in the position for taking materials, the piston rod of the second cylinder extends into the central hole of the workpiece which is pushed out by the first cylinder, then draws back and takes the workpiece out. The clamping mechanism clamps the workpiece. When the swing arm is in the position for feeding, the clamping mechanism unclamps the workpiece, and the piston rod of the second cylinder extends out and sends the workpiece to the special fixture of the machine tool. The automatic feeding mechanism has the advantages of being simple in structure, accurate in movement, low in cost and the like.
Description
Technical field
The utility model relates to a kind of mechanical feed mechanism of lathe, and especially a kind of being used for will have the feeding mechanism of the workpiece feeding lathe special fixture of centre bore.
Background technology
Existing machine tool is in the process of processing work, step with workpiece feeding lathe special fixture clamping to be processed, more employing is manual to be finished, manual feeding working (machining) efficiency is low, can not satisfy requirements of large-scale production, and occur error in the process of feeding and clamping easily, workpiece scrappage height is in the processing cost that has just increased workpiece virtually.Certainly, along with development of science and technology, the numerical control machining center that feeding and processing are automatically finished has appearred in the market, its feeding procedure adopts manipulator to finish, the existing mechanical hand can be realized the spatial movement of multi-angle, can accurately workpiece to be processed be fed in the special fixture to clamp, and after workpiece machines workpiece be taken out, can be used for processing the workpiece of multiple shape and specification, but the manipulator of this drawing-in device is structurally comparatively complicated and cost is high.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art, and a kind of simple in structure, action mechanical feed mechanism accurate, with low cost is provided.
The purpose of this utility model realizes by following technical solution:
A kind of mechanical feed mechanism, be used for to have the special fixture of the workpiece feeding lathe of centre bore, it is characterized in that: comprise the feeding device that is used for workpiece is delivered to position to be processed, be arranged at the swing arm on the lathe, connect to drive that swing arm gets that material level is put and the feeding position between the motor swung, the workpiece that is used for being positioned at position to be processed is released first cylinder of feeding device, be arranged at second cylinder in the swing arm, and be arranged at clamp mechanism in the swing arm, the piston rod of second cylinder is arranged in the centre bore with workpiece suitable, get material level and put when swing arm is positioned at, second cylinder piston rod stretches into to be withdrawn behind the centre bore of the workpiece of first cylinder release workpiece is taken out, and by the clamp mechanism clamping work pieces, when swing arm is positioned at the feeding position, clamp mechanism is unclamped workpiece, and second cylinder piston rod stretches out to be sent into workpiece in the special fixture of lathe.
Further, described clamp mechanism comprises the slide rail that is arranged in the swing arm, is actively set in slide on the slide rail, drives the 3rd cylinder that slide slides along slide rail and is arranged at clamping device on the slide.
The utlity model has following beneficial effect:
During work, feeding device is delivered to position to be processed with workpiece, first cylinder will be in the workpiece of position to be processed and release, the motor-driven swing arm is rocked to gets material level and puts, workpiece was taken out in withdrawal after the piston rod of second cylinder stretched in the workpiece centre hole that is pushed out, the clamp mechanism clamping work pieces, the motor-driven swing arm is rocked to the feeding position then, clamp mechanism is unclamped workpiece, the piston rod of second cylinder stretches out to be sent into workpiece in the special fixture of lathe, finishes feeding, and enters next circulation, compared with prior art, the utility model is simple in structure, action accurately, with low cost.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of swing arm of the present utility model.
The specific embodiment
Shown in seeing figures.1.and.2, a kind of mechanical feed mechanism, be used for to have the special fixture (not shown) of the workpiece 2 feeding lathes of centre bore, comprise the feeding device 3 that is used for workpiece 2 is delivered to position to be processed, be arranged at the swing arm 5 on the lathe, connect to drive that swing arm 5 gets that material level is put and the feeding position between the motor 4 swung, the workpiece 2 that is used for being positioned at position to be processed is released first cylinder 1 of feeding devices 3, be arranged at second cylinder 8 in the swing arm 5, and be arranged at clamp mechanism 7 in the swing arm 5, the piston rod of second cylinder 8 is arranged in the centre bore with workpiece 2 suitable, get material level and put when swing arm 5 is positioned at, second cylinder, 8 piston rods stretch into to be withdrawn behind the centre bore of the workpiece 2 of first cylinder, 1 release workpiece are taken out, and by clamp mechanism 7 clamping work pieces, when swing arm 5 is positioned at the feeding position, clamp mechanism 7 is unclamped workpiece, second cylinder, 8 piston rods stretch out to be sent into workpiece 2 in the special fixture of lathe, clamp by special fixture, process.
Wherein, clamp mechanism comprises the slide rail that is arranged in the swing arm, be actively set in slide on the slide rail, drive the 3rd cylinder that slide slides along slide rail and be arranged at clamping device on the slide, is known prior art, just no longer is shown specifically in the drawings.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
Claims (2)
