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

[0030] 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...

Abstract

The invention relates to the technical field of slicing machines, which provides a sample positioning device and a slicing machine. A rotating member can be deflected and adjusted in two directions bya first adjusting mechanism and a second adjusting mechanism arranged perpendicularly to each other without interference. The rotation of a first adjusting knob and the rotation of a second adjustingknob are respectively converted into reciprocating movement of a first connecting block and a second connecting block through tooth fitting, and then converted into movement of a spherical bearing mechanism, and then the rotation of the rotating member is driven, so that the adjustment accuracy is high. Moreover, during the adjustment process, the rotating member, a locking part and a shell are in arc contact, so that the parts can not be worn out during the adjustment process, thus ensuring the accuracy of adjustment and realizing the multi-angle adjustment.

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...
