Problems solved by technology
[0003] However, the existing technology usually directly uses the screw to withstand the rotating body, or uses vertical rods in two directions to drive the rotating body to rotate. The manufacturing process requirements for each structural part are relatively high, and it is prone to wear and tear, resulting in a low defect rate. high
In addition, on the angle display, there is only one zero point indication in the horizontal and vertical directions, and the display of the deflection angle is incomplete. When adjusting the sample angle, it is easy to confuse the adjustment direction, which is not convenient for the operator to operate.

Embodiment 1
[0024] Please also refer to figure 1 , figure 2 and image 3 , Embodiment 1 of the present invention provides a sample positioning device, which is used to position a sample. The sample positioning device includes a housing 11, a first adjustment mechanism 12, a second adjustment mechanism 13, a spherical bearing mechanism 15, an eccentric Rod 16 , limit rod 17 , rotating member 18 and locking member 19 . The rotating member 18 is used to fix the sample. The rotating member 18 is partly accommodated in the housing 11 and is in arc surface contact with the housing 11. The spherical bearing mechanism 15 is accommodated in the housing 11 and connected to the rotating member 18. To drive the rotating member 18 to rotate, the first adjusting mechanism 12 and the second adjusting mechanism 13 partly extend into the housing 11 and are respectively connected with the spherical bearing mechanism 15, and the first adjusting mechanism 12 and the second adjusting mechanism 13 vertical...

The invention relates to the technical field of slicing machines, and provides a sample positioning device and a slicing machine. The sample positioning device comprises a shell, a first adjusting mechanism, a second adjusting mechanism, a spherical bearing mechanism, an eccentric rod, a rotating piece and a locking piece, the rotating piece is partially contained in the shell and is in contact with the arc surface of the shell, the spherical bearing mechanism is contained in the shell and is connected with the rotating piece, the first adjusting mechanism and the second adjusting mechanism are perpendicularly arranged, the first adjusting mechanism and the second adjusting mechanism partially extend into the shell and are connected with the spherical bearing mechanism correspondingly, thefirst adjusting mechanism or the second adjusting mechanism is rotated to drive the spherical bearing mechanism to move and then drive the rotating piece to rotate, the locking piece is partially contained in the rotating piece and is in contact with the arc surface of the rotating piece, and the eccentric rod penetrates through the shell and the rotating piece in sequence and cooperates with thelocking piece so as to lock or unlock the rotating piece. The sample positioning device and the slicing machine have the advantages that abrasion cannot occur in the adjusting process, and multi-angle adjustment can be realized.
Description
technical field [0001] The invention relates to the technical field of slicers, in particular to a sample positioning device and a slicer. Background technique [0002] Commonly used sample positioning devices on the market adjust the horizontal and vertical angular deflection of the sample holder by adjusting the horizontal and vertical knobs to meet different slicing requirements within a certain range. [0003] However, the existing technology usually directly uses the screw to withstand the rotating body, or uses vertical rods in two directions to drive the rotating body to rotate. The manufacturing process requirements for each structural part are relatively high, and it is prone to wear and tear, resulting in a low defect rate. high. In addition, on the angle display, there is only one zero point indication in the horizontal and vertical directions, and the display of the deflection angle is incomplete. When adjusting the sample angle, it is easy to confuse the adjust...
