Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, illustrative examples therein with
And explanation is only used for explaining the utility model, but it is not intended as to restriction of the present utility model.
As shown in figure 1, a kind of metallographic specimen clamper described in present embodiment, it includes rack slide bar 1, U-shaped
Seat 2, bolt 3, retaining sleeve 4, sliding block 5, screw rod 6, worm gear 7, worm screw 8, clamping fixture seat 9, elastic fixture 10, left partial gear 11,
Right partial gear 12；Rack slide bar 1 is interspersed in U-shaped seat 2；Left partial gear 11 is provided with below the hock of rack slide bar 1
With right partial gear 12；Engaged between left partial gear 11 and right partial gear 12；Retaining sleeve 4 is fixed by bolt 3
On rack slide bar 1；Worm gear 7 and worm screw 8 are installed inside retaining sleeve 4；Engaged between worm gear 7 and worm screw 8；Screw rod 6 passes through snail
Wheel 7, screw rod 6 connects with the internal threading arrangement of worm gear 7；The top of screw rod 6 is provided with sliding block 5；The bottom of screw rod 6 is provided with clamping fixture seat 9；
Elastic fixture 10 is arranged on the bottom of clamping fixture seat 9；Sliding block 5 is located in the square space 4-1 in retaining sleeve 4；Clamping fixture seat 9 is positioned at clamping
In cylindrical space 4-2 in set 4；Elastic fixture 10 is the hollow taper set for being provided with cross gap.
Further：The sliding block 5 is cuboid, and the slider designs of cuboid are placed in square space 4-1 and can prevented
Screw rod 6 follows worm gear 7 to rotate..
Further：The clamping fixture seat 9 is cylinder.
Further：The elastic fixture 10 is the elastic hollow taper set for being provided with cross gap, in the band of screw rod 6
When dynamic clamping fixture seat 9 and elastic fixture 10 move up and down, elastic fixture 10 can be under the elasticity of itself by the cylinder of retaining sleeve 4
Shape space 4-2 outer wall realizes radial contraction, has reached the purpose of promptly metallographic test specimen.
Further：The left partial gear 11 is tooth form symmetrical expression partial gear.
Further：The right partial gear 12 is half of tooth form partial gear.
A kind of metallographic specimen clamper described in the utility model, its operation principle are：Hand-held metallographic test specimen is placed on
In elastic fixture 10, by rotary worm 8, drive turbine 7 to rotate, because turbine 7 and screw rod 6 are coupled for nut screw, and slide
Block 5 limits the rotation of screw rod 6, so screw rod 6 can only move up and down under the rotation of turbine 7, when needing to clamp metallographic specimen,
Move up screw rod 6, elastic fixture 10 shrinks inwards in the presence of cylindrical space 4-2, so as to step up metallographic specimen.When
When needing to unclamp sample, opposite direction rotary worm 8, drive the opposite direction of turbine 7 to rotate, move down screw rod 6, elastic fixture 10
Progressively break away from cylindrical space 4-2 constraint so that elastic fixture 10 is flared out in the presence of natural resiliency power, so as to
Loosen metallographic specimen；This mode of stepping up make use of the self-locking performance performance of worm and gear, and clamping is reliable, will not loosen during work,
And clipping operation is simple.Then lift in height device is fixed in U-shaped seat 2, lift in height device is located at below metallographic test specimen,
Upper polishers are installed, the height of polishing machine is adjusted by lift in height device on lift in height device；Extraneous motor drives left
Partial gear 11 rotates clockwise, and left partial gear 11 engages with right partial gear 12, drives right partial gear 12
Rotate counterclockwise, right partial gear is engaged 12 with rack slide bar 1, and band carry-over bar slide bar 1 is moved to the left；Left partial gear
11 go to the gear teeth on right side and right partial gear 12 when can not will engage, and now the left side gear teeth of left partial gear 11 are firm
Good and rack slide bar 1 gear teeth meshing, band carry-over bar slide bar 1 move right；Nibbled with hour rack slide bar 1 and right partial gear 12
Close, so as to drive right partial gear 12 to rotate clockwise, right partial gear 12 is resetted；When right partial gear 12 is suitable
Hour hands are turned to when can not will be engaged with rack slide bar 1, and left partial gear 11 just engages with right partial gear 12 again,
Right partial gear 12 is driven to rotate counterclockwise, right partial gear 12 engages with rack slide bar 1 again, band carry-over bar slide bar 1
It is moved to the left, so circulation, realizes in the presence of two partial gears, 1 continuous linear reciprocating motion of rack slide bar, so as to
Retaining sleeve 4 is driven to move back and forth.
A kind of metallographic specimen clamper described in the utility model, it uses elastic clamp metallographic test specimen, at two
Retaining sleeve and metallographic test specimen and rack slide bar is driven to do straight reciprocating motion together under the rotation of partial gear, so that metallographic
Test specimen uniform force, reduce the working strength of operating personnel, save the time, improve the utilization rate of polishing cloth and stabilize throwing
The quality of light.
Described above is only better embodiment of the present utility model, therefore all according to described in the utility model patent application range
The equivalent change or modification done of construction, feature and principle, be included in the utility model patent application range.
