According in an embodiment of the present utility model, described lifting unit also includes the straight line lifting fortune for described top board
The dynamic lifting guidance set that guiding is provided.
According in an embodiment of the present utility model, described lifting guidance set includes lifting slider and the liter matching
Fall guide rail.
According in an embodiment of the present utility model, described binder guidance set includes the binder slide block matching and pressure
Material guide rail.
Lifting hold-down mechanism of the present utility model can carry out being fixed processing to the material on material conveyor belt, prevents work
Part is subjected to displacement in process engineering, realizes the accurate processing of part, can effectively improve the process velocity of workpiece, saves and adds
Between man-hour.And, this lifting hold-down mechanism is by controlling the work of lifting actuator come the rising or falling speed of controlling organization and compression
Power, enters row buffering by elastic component, can reduce the lifting impact to workpiece for the hold-down mechanism, workpiece pressing is carried out simultaneously solid
Fixed.This lifting hold-down mechanism is be applied to the machine internal material transport mechanism such as chip mounter, inserter and laser marking machine.
Brief description
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the perspective view of the lifting hold-down mechanism of one embodiment of this utility model；
Fig. 2 is the structural representation of the lifting unit of lifting hold-down mechanism shown in Fig. 1.
Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.It should be appreciated that specific embodiment described herein is only in order to explain
This utility model, is not used to limit this utility model.
As shown in figure 1, according to the lifting hold-down mechanism of one embodiment of this utility model mainly by lifting unit 30 and pressure
Material unit 40 is constituted.Lifting unit 30 may be installed on the base plate 10 of corresponding material transmitting mechanical, and binder unit 40 may be installed
In the frame 20 of corresponding material transmitting mechanical.Those skilled in the art it will be apparent that, be only this utility model shown in Fig. 1
One application example of lifting hold-down mechanism, is not the restriction to this utility model protection domain.In specific application, this liter
The lifting unit 30 of fall hold-down mechanism and binder unit 40 can be installed according to the matching relationship in practical application machinery.
Specifically as shown in Fig. 2 lifting unit 30 is mainly by cylinder 31, top board 32, spring 33, riser guide 34, mounting blocks
35th, lifting slider 36 is constituted.Cylinder 31 is as the lifting actuator of this lifting unit 30, straight vertical for driving top board 32
Line elevating movement.Top board 32 is connected to the outfan of cylinder 31 by least one spring 33.And, the bottom of top board 32 connects
Mounting blocks 35, this mounting blocks 35 is provided with lifting slider 36, and lifting slider 36 is prolonged with the vertically straight line being fixed on base plate 10
The riser guide 34 stretched is slidably matched.The cooperation of lifting slider 36 and riser guide 34 constitutes lifting guidance set, is top board 32
Lifting provide guide effect.
Again as shown in figure 1, binder unit 40 is mainly made up of holding pad 41 and binder guidance set.Holding pad 41 is arranged at
The top of top board 32, only during top board 32 rising, holding pad 41 just can be contacted thus being driven by top board 32 with top board 32
And ramp under the guiding of binder guidance set, thus compress the workpiece needing processing.Binder guidance set also can by with
Binder slide block (not shown) and the binder guide rail 42 of the vertical lines extension being installed in frame 20 that holding pad 41 connects
Be slidably matched composition.
The specific work process of above-mentioned lifting hold-down mechanism is as follows:
When material conveyer belt is started working, material reaches Working position, is accurately located by other mechanisms and postpones, gas
Cylinder 31 begins to ramp up, and drives top board 32 to move along riser guide 34 by spring 33, top board 32 touches pressure during rising
Flitch 41 is so that holding pad 41 moves upwards along binder guide rail 42 straight line；When cylinder 31 rises to end of travel, holding pad 41
Compression needs the workpiece of processing.In the process, by spring 33, cylinder 31 can be slowed down during top board 32 rises
Power and speed, are converted into the pressure of spring 33 so that whole lifting hold-down mechanism to the thrust of workpiece is the power of cylinder 31
Elastic force after spring 33 compression.The size of this thrust to workpiece for lifting hold-down mechanism then can be by adjusting spring 33
Decrement and spring constant are being adjusted.After Work-sheet pressing, contact processing can be carried out to workpiece it can be ensured that work
Part will not be shifted over the machining accuracy it is ensured that workpiece in process.After the completion of work pieces process, cylinder 31 begins to decline,
Top board 32 declines in the drive lower edge riser guide 34 of cylinder 31；After dropping to certain distance, top board 31 is separated with holding pad 41,
Holding pad 41 declines along binder guide rail 42 in the presence of self gravitation, and now holding pad 41 and workpiece separate, material conveyer
Structure sends manufactured workpiece, and is sent into unprocessed new workpiece, and now lifting feeding pressure mechanism repeats above-mentioned action, Zhou Erfu
Begin.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all this
Any modification, equivalent and improvement made within the spirit of utility model and principle etc., should be included in this utility model
Protection domain within.
