It wherein, include pressed seat 11 in pressing device 1, pressed seat 11 is arranged in mounting base 3 in half-surrounded relative to adding
The side that station is set, in order to avoid mechanical interference is caused in process.The rear of pressed seat 11 is provided with pusher 12, pushes away
The lower hinge of dynamic device 12 is articulated with bull stick 13, in the central location of pressed seat 11 on pedestal on the piston rod of pusher 12
Recessing groove 111 is offered, bull stick 13 is placed in the recessing groove 111, enables bull stick 13 as center, more convenient in tooling
Workpiece be clamped.And two sides are articulated with pressed seat 11, and the other end in bull stick 13 is provided with compressed part.
In the present embodiment, compressed part includes a compression bar 14, and one end of compression bar 14 is connected in bull stick 13, can be one
Molding or the mode being welded to connect.In the angle between 15 ° to 30 ° between compression bar 14 and bull stick 13.And the work of pusher 12
It is in substantially 90 ° of angle between stopper rod and bull stick 13.In the state of undressed, compression bar 14 is in a horizontal state.
The end of compression bar 14 is provided with briquetting 141, briquetting 141 can be dismountable mode, can also be and compression bar
14 integrally formed modes.Briquetting 141 and compression bar 14 are in 90 ° of settings, after facilitating compression bar 14 to rotate, briquetting 141 can with it is to be added
The Workpiece clamping of work.
Horizontal distance between compression bar 14 and pivotal point is L1, the hinge joint and pivotal point of the piston rod and bull stick 13 it
Between horizontal distance be L2, and L1 < L2.By above-mentioned setting, entire hold-down mechanism uses lever principle, i.e. compression bar 14 and pivot
Horizontal distance between turning point is L1 (power arm), between the piston rod and the hinge joint and pivotal point of bull stick 13 it is horizontal away from
From for L2 (resistance arm), and power arm is less than resistance arm, makes to apply and obtains resistance and become to be amplified after power, acts on work
The pressure of part is bigger, clamps stable and firm.
It should be noted that the piston rod of driver 23 ejects in process, meanwhile, driver 23 and level
Angle between face slightly increases, and under the action of piston rod ejects upwards, bull stick 13 is rotated by the center of circle of pivotal point, i.e. compression bar
14 are pressed downward, and the angle between piston rod and bull stick 13 is gradually reduced at this time.
That is, bull stick 13 tilts down 15 ° to 30 ° with pivotal point, can also be passed through by bearing 151 in pivotal point
In addition bearing mounting base 15 is set, bearing 151 is installed in bearing mounting base 15, bearing mounting base 15 can make pivoting centre knot
Structure is more stable.
It can be said that mounting base 3 can be the plate of one piece of strip in the present embodiment, mounting base 3 is close to compression dress
It sets 1 one end to be connected with pressed seat 11, the mode being connected in the present embodiment can fix for screw.In mounting base 3
It is removably connected with positioning tool 31, after workpiece to be processed replacement, under positioning tool 31 being dismantled, installs adaptation
In the positioning tool 31 of workpiece.
In addition, being provided with gag lever post 32 between positioning tool 31 and pressed seat 11 above mounting base 3, gag lever post 32 is used
It is limited in the extreme lower position in 14 decline process of compression bar, avoids briquetting 141 from pushing and shape excessively is caused to workpiece extruding
Become, certainly, gag lever post 32 can be screw rod, it can be adjusted depending on the situation.
Driver 23 and pusher 12 are preferentially adopted as oil cylinder in the present embodiment, and there is pressure to stablize, and adjustment is accurate
The advantages of.
Embodiment 2:
It is on the basis of embodiment 1, vertical in one end of the close pressing device 1 of positioning tool 31 referring to attached drawing 2 and 3
It is provided with positive stop end 311, in the other end relative to pressing device 1, is provided with horizontal clamping device 2.Horizontal clamping device 2
Including horizontal base 21, the charging ram 22 driven by driver 23 is provided with above horizontal base 21, charging ram 22 is horizontally disposed,
Its face positive stop end 311, the other end of charging ram 22 are provided with driver 23.As a result, after driver 23 drives, charging ram
22 transport horizontally forward, carry out the clamping in horizontal direction to the workpiece being located on positioning tool 31.
Certainly, rubber block 24 can be set in the section portion of charging ram 22, has made charging ram 22 after contacting with workpiece, had
There is certain buffering capacity, workpiece caused by direct rigid contact is avoided to deform.Further, it is additionally provided in mounting base 3
Alignment block 33 is provided through alignment hole (not illustrating in figure) on alignment block 33, and alignment block 33 can be set multiple, is pushed away
Expect that bar 22 passes through the alignment hole, the end of charging ram 22 can effectively be made to keep alignment, it will not sideslip.
The following are being further elaborated to clamping process, workpiece is placed on positioning tool 31 first, is then driven
Driver 23 draws close charging ram 22 to workpiece, after charging ram 22 and workpiece are contradicted, the positive stop end 311 in the other side
Under the action of, that is, realize the positioning in horizontal direction.Then, the piston rod driving of the pusher 12 of pressing device 1, makes bull stick
13 are rotated with pivotal point, i.e. the briquetting 141 of compression bar 14 rotates clockwise, and are gradually declined, can be right after finally contradicting workpiece
It is clamped on vertical direction.After completing to clamp, pedestal is fed by mounting base 3, pressing device 1 and horizontal clamping device 2
Synchronization is transported forward, until arriving Working position, the both ends of workpiece are simultaneously by the wheel grinding of grinding head device, after grinding repeatedly,
Processing is completed, high-precision requirement is reached.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
