Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by detailed description of the invention.
As shown in Figure 1 to Figure 3, a kind of hold down gag includes fixture, sliding component 3, waves hold-down mechanism and driver 9.
Wherein, on the one hand fixture provides mounting platform for other parts, on the other hand serves the effect of carrying workpiece, at this
In embodiment, for the installing space enough to the offer of each parts, then fixture uses the structure of two pieces of fixed plates, as
Shown in Fig. 1 to Fig. 3, including the first fixed plate 11 be placed in the second fixed plate 12 on this first fixed plate 11 end face.Certainly,
In view of different working environments, it is possible to this anchor designs to be become one piece of fixed block, in a word, the concrete structure ability of fixture
Field technique personnel can be designed according to the actual requirements.Driver 9 is installed on the bottom surface of the first fixed plate 11, at the present embodiment
In, driver 9 is preferably cylinder, and in cylinder, the free end of piston rod is fixedly linked with sliding component 3.Select cylinder as driver
It is because being easier to find in industrial and mining establishment source of the gas, and facilitates implementation Automated condtrol by controlling the supply of gas.
In addition to using cylinder, it is possible to select propulsion motor as driver.
As shown in Figures 2 and 3, sliding component 3 is arranged on the bottom surface of 3 first fixed plates 11 in such a way as to be reciprocable.
Wave hold-down mechanism to be connected with sliding component 3 with the second fixed plate 12 through the first fixed plate 11, and shake with the slip of sliding component 3
Pendulum, by Work-sheet pressing in the second fixed plate 12.
In the present embodiment, as it is shown in figure 1, wave hold-down mechanism to include depression bar 21 and connecting rod 22.One end of depression bar 21 is
Pivot end, this end and the second fixed plate 12 pivot joint.Preferably, as it is shown in figure 1, depression bar 21 is fixed by pivotal axis 5 and second
Plate 12 pivot joint, the two ends of this pivotal axis 5 are all sleeved on the second bearing, and the second bearing is packed in the second fixed plate 12.So
A kind of pivot structure makes connecting rod 22 more smooth when swinging around pivotal axis 5.For the ease of the installation of the second bearing, then,
Preferably, the second fixed plate 12 being fixed with bearing bracket stand 6, the second bearing is arranged in bearing bracket stand 6.
As shown in figures 1 and 3, the other end of depression bar 21 is for compressing end, for workpiece pressing.Preferably, the pressure of depression bar 21
Tight end is provided with pressure head 7, and on the one hand arranging of pressure head 7 make workpiece more securely be compressed, and on the other hand can be adopted by pressure head 7
Make with colloid, so can prevent from workpiece is caused scuffing.
As it is shown in figure 1, one end of connecting rod 22 is by the pivot end pivot joint of another pivotal axis with depression bar 21, this pivotal axis
Axis is parallel with the axis of pivotal axis 5.
As shown in Figures 2 and 3, sliding component 3 being provided with the first chute 31, the bearing of trend of this first chute 31 is sliding with this
The angle moving part 31 translation direction is acute angle.The other end of connecting rod 22 is sliding-end, slides in the first chute 31 in this end.When
When piston rod in cylinder stretches out, sliding component 3 moves forward, and the first chute 31 also moves forward, thus forces the sliding-end of connecting rod 22 with
The movement of one chute 31 is glided in this first chute 31, and the position of this sliding-end moves down, and forces the other end of connecting rod 22 to drive
The pivot end of depression bar 21.The pivot end of depression bar 21 constantly moves down along with connecting rod 22 sliding-end, upwards will put around pivotal axis 5
Dynamic, the compression end on depression bar 21 is opened, and pressure head 7 departs from workpiece, thus is decontroled by workpiece.When the piston rod in cylinder shrinks,
Move after sliding component 3, wave hold-down mechanism swung downward, and then realize pressure head 7 by Work-sheet pressing in the second fixed plate 12.
Wave hold-down mechanism in addition to the structure of depression bar 21 and connecting rod 22 in employing the present embodiment, it is also possible to select integral type
Swing arm, one end of this swing arm for compress end, the other end is sliding-end, and this sliding-end slides in the first chute 31,
Pivotal axis 5 and the second fixed plate 12 pivot joint are passed through in the middle part of swing arm.
In the present embodiment, the sliding-end of connecting rod 22 is in moving process, in order to one, this end guiding, and makes
This sliding-end can move up and down smoothly, preferably then, the first fixed plate 11 is fixed with contiguous block 4, this contiguous block 4
On be provided with the second chute 41, the bearing of trend of this second chute 41 is vertical with the translation direction of sliding component 3, the sliding of connecting rod 22
End slides in the second chute 41, and then makes this second chute 41 serve the effect of gathering sill.
In this embodiment, it is preferred that, the sliding-end of connecting rod 22 is provided with two clutch shaft bearings, wherein, one first
In bearing is placed in the first chute 31 and with the inwall rolling friction of this first chute 31, another clutch shaft bearing is placed in the second chute
In 41 and with the inwall rolling friction of this second chute 41.Thus sliding-end sliding friction in chute is improved to rolling and rubs
Wipe, greatly reduce frictional dissipation.
It addition, in order to ensure sliding component 3 on the bottom surface of the first fixed plate 11 the most steady, preferably then,
The bottom surface of the first fixed plate 11 is fixed with guide rail 8, sliding component 3 offers the guide groove coordinated with this guide rail 8 slide guide, passes through
The setting of guide rail and guide groove ensure that the moving stability of sliding component 3.
The hold down gag that the present embodiment is provided, change prior art utilize rotary cylinder to complete pressing action and then
By the mode of Work-sheet pressing, driven by the driver drives sliding component being arranged on fixture and wave hold-down mechanism and wave,
Thus by Work-sheet pressing on fixture, this hold down gag takes up room less, and it is easy to control, it is easy to accomplish automatization.
Obviously, above-described embodiment of the present utility model is only used to understand explanation this utility model example, and
It it is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, in described above
On the basis of can also make other changes in different forms.Here without also all of embodiment being given
Exhaustive.All any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, should be included in
Within this utility model scope of the claims.
