The torque needed by the drive system of the utility model is reduced, thus achieving the speed control of the slider and hovering at any location; the utility model is also capable of controlling the seesaw motion of the slider, and achieves the numerical control of the slider by controlling the servo motor.

Description

The servo-drive multi-link lever press
Technical field
The utility model relates to a kind of link lever press, relates in particular to a kind of improvement of link press driving mechanism.
Background technology
In the prior art, above the workbench of forcing press, connect the slide block that can vertically slide by connecting rod, the other end of connecting rod is hinged on the crank, crank is connected with driven gear on being bearing in frame, this driven gear and driving gear external toothing, driving gear center fixation sprocket drive spindle, slide as the need slide block, then must control described gear shaft transmission, traditional forcing press is promptly installed motor on frame, motor shaft end is through belt wheel and V-belt transmission, the driven pulley that driving is arranged on the gear shaft end rotates, and the gear shaft end is provided with clutch, and driven pulley rotates through the clutch gear shaft, clutch adopts positive clutch or air operated friction clutch more, in when work, motor remains rotation, and the folding by clutch drives slide block and moves up and down or stop, but the slide block of this forcing press can not be realized accurate movement, the inertia of transmission mechanism is big, and slide block can't hover at an arbitrary position, and the movement velocity of slide block can not be controlled.
The utility model content
The utility model provides a kind of use driven by servomotor at above technical problem, can control slide block movement speed and the position of hovering, and can control the servo-drive multi-link lever press of the direction that moves up and down of slide block arbitrarily.
The technical solution of the utility model is: comprise slide block, drive motors, be connected the transmission mechanism between slide block and the drive motors, described drive motors is a servomotor; Be connected by guide pillar, guide pin bushing between slide block and the forcing press; Described transmission mechanism comprises and is connected on one's body support link of forcing press, is connected crank on the servomotor, is connected connecting rod and toggle link on the slide block guide post; Toggle link has output arm and support arm, and support arm arm end and support link are hinged, and output arm arm end and connecting rod are hinged, and elbow bent angle and crank are hinged.
The toggle link output arm is shorter than support arm, and the length ratio is that angle is 20~42 degree between 1: 1.08~1.50, two arms between the two.
The length ratio is 1: 1.80~3.00: 2.98~4.20 between crank, connecting rod, support link.
Servo-drive multi-link lever press of the present utility model, the transmission mechanism required torque is little, can realize ram speed control and hover at an arbitrary position, and can control moving up and down of slide block arbitrarily.The slide block that above workbench, connects and can vertically slide by the straight line guide pillar, straight line guide pillar and connecting rod are hinged by bearing pin, and then are that toggle link is connected with special triangle pole mechanism, and toggle link is unsteady to be connected on crank, support link and the connecting rod.Be converted into the rectilinear motion of slide block with rotatablely moving.
During the utility model work, servomotor rotates, the drive crank rotates, crank is done swing before and after driving elbow-bar mechanism, the motion of elbow-bar mechanism drivening rod, connecting rod drives the straight line guide pillar by bearing pin and moves up and down, and slides up and down thereby drive slide block, and the support link that links to each other with frame play supporting role at the volley.Because servomotor can be realized speed and Position Control, thereby can realize numerical control is carried out in the movement velocity and the position of slide block, therefore can realize control to the slide block movement track; Simultaneously, the elbow-bar mechanism by after optimizing can reduce the required driving torque of system, thereby can save the lathe energy consumption.Compared with prior art, save gear drive, flywheel transmission and clutch brake device, simplified transmission mechanism, make structure more compact, reasonable, can energy efficient, make the easier control of slide block movement, the utility model can be realized the slide block movement numerical controlization by the control servomotor.
Description of drawings
Fig. 1 is the utility model operation principle schematic diagram
1 is servomotor among the figure, the 2nd, and crank, the 3rd, toggle link, the 4th, support link, the 5th, connecting rod, the 6th, guide pin bushing, the 7th, guide pillar, the 8th, slide block.
Fig. 2 is the utility model motion state sequential chart
A is near the bottom dead centre state among the figure, and b is the slide block state that moves upward, and c is near the top dead-centre state, and d is that slide block moves downward state.
The specific embodiment
As Fig. 1, the utility model comprises slide block 8, drive motors, is connected the transmission mechanism between slide block 8 and the drive motors, and drive motors is a servomotor 1; Be connected by guide pillar 7, guide pin bushing 6 between slide block 8 and the forcing press; Transmission mechanism comprises and is connected on one's body support link 4 of forcing press, is connected crank 2 on the servomotor 1, is connected connecting rod 5 and toggle link 3 on the slide block guide post 7; Toggle link 3 has output arm and support arm, and support arm arm end and support link 4 are hinged, and output arm arm end is connected with connecting rod hinge 5, and toggle link 3 bent angles and crank 2 are hinged.
Toggle link 3 output arms are shorter than support arm, and the length ratio is that angle is 20~42 degree between 1: 1.08~1.50, two arms between the two.
Crank 2, connecting rod 5,4 length ratios of support link are 1: 1.80~3.00: 2.98~4.20.
As Fig. 2, during the utility model work, servomotor 1 rotates, drive drive rod 2 and rotatablely move, the drive rod 2 that rotatablely moves drives toggle link 3, because an end of toggle link 3 links to each other with support link 4, so can the swing campaign, drive guide pillar 7 by connecting rod 5 then and move up and down in guide pin bushing 6, the guide pillar 7 that moves up and down drives slide block 8 and moves up and down, thereby realizes punching press.Wherein, multi-connecting-rod mechanism has the characteristic that changes movement locus and reduce required torque, through optimizing many connecting rods size, can find the curve movement that is fit to punching press, at last, can carry out part adjustment to curve by servomotor again, can satisfy the punching press and the drawing process of different materials, workpiece.Among the figure chronologically: a is near the bottom dead centre state, and b is the slide block state that moves upward, and c is near the top dead-centre state, and d is that slide block moves downward state.
