Technical Field
The invention belongs to the field of clamps, and particularly relates to an blade clamping device and a cutter with an adjustable cutting angle, which comprises the device.
Background
In biological specimen cutting, the blade clamping device is a device for positioning and clamping a cutting blade, and the existing mode for clamping the blade is generally composed of two or more discrete rigid parts, and the clamping of the blade is realized by combining parts such as screws and the like.
By adopting the clamping mode, is inconvenient to mount, and secondly, the clamping force of the blade is uncontrollable, point contact or line contact constraint is easily formed for a precision thin blade with poor rigidity or brittleness, large pressure/pressure can be generated on the blade, the blade is easily damaged, and meanwhile, the pressure/pressure is unevenly distributed on the blade, so that the blade generates uncontrollable deformation on a non-cutting plane, a smooth cutting surface cannot be obtained in the cutting process, and the integrity of data acquisition in subsequent microscopic optical imaging is influenced.
In addition, the current cutting angle of the cutter is complex in adjustment mode and low in precision.
Disclosure of Invention
The invention provides blade clamping devices and a cutter with an adjustable cutting angle, aiming at providing blade clamping devices suitable for precision blades such as ceramic blades, stainless steel blades and the like for flat push type cutting of frozen or paraffin-embedded samples and the cutter with the adjustable cutting angle, aiming at solving the technical problems of inconvenient blade installation and complex cutter cutting angle adjusting mode in the prior art.
To achieve the above object, according to aspects of the present invention, there are provided blade clamping devices, which include a clamp body and a fastener, wherein the clamp body includes a fixed base connected by a flexible hinge and a pressing plate rotatable around the flexible hinge to form a blade mounting area and a fastening area on two sides of the flexible hinge, the fixed base of the fastening area is provided with a fastener mounting hole, and the fastener passes through the fastener mounting hole and abuts against the pressing plate at end to fix the blade in the blade mounting area.
In the blade holding device of the present invention, the pressing plate and the fixing base are respectively provided with a boss and a groove, so that a step is formed in the blade mounting region.
Preferably, a portion of the pressure plate from the boss in a direction away from the flexible hinge flexibly engages the blade.
Preferably, the thickness of the flexibly fitted portion of the pressure plate is gradually reduced.
Preferably, the clip body is body molded.
According to another aspect of the invention, cutters with adjustable cutting angles are provided, which comprise a fixed frame and the cutter clamping device, wherein the fixed frame is provided with an angle adjusting component and a cutter supporting rod, a fixture body in the cutter clamping device is provided with a cutter supporting rod mounting hole, the cutter clamping device is fixed on the cutter supporting rod through the cutter supporting rod mounting hole, and the cutter supporting rod is connected with the angle adjusting component.
Preferably, the angle adjusting assembly includes a flexible connecting plate, a movable plate and a displacement adjusting member, the flexible connecting plate includes a fixed plate and a fixed plate ii connected through a flexible connection point, the end of the cutter supporting rod is fixed on the fixed plate ii, the other end is fixed on the movable plate, the displacement adjusting member is movably disposed on the fixed frame, and the end is in contact with the movable plate, so that the displacement adjusting member drives the movable plate, the cutter supporting rod and the fixed plate ii to rotate around the flexible connection point when moving.
Preferably, the displacement adjusting member is a nut , and the fixing frame is provided with a screw hole matched with the nut .
Preferably, the fixed plate , the second fixed plate and the movable plate are all arranged on the fixed frame through a second nut, and two ends of the cutter supporting rod are respectively fixed on the second fixed plate and the movable plate through a third nut and a third fixed plate.
Generally speaking, compared with the prior art, the technical scheme of the invention has the advantages that the lever structure is formed by connecting the fixed base and the pressing plate through the flexible hinge, and the angle of the cutter is precisely adjusted through the angle adjusting component, so that the following beneficial effects can be achieved:
(1) the invention provides blade clamping devices, which clamp blades by adopting the lever principle and are convenient to install.
(2) The invention adopts the step formed by the boss of the pressure plate and the groove of the fixed base to limit the blade, thereby ensuring that the position of the blade is unchanged when the blade is replaced and realizing repeated positioning.
(3) The thickness of the flexible matched part of the pressure plate and the blade is gradually reduced to ensure that the clamping device is in surface contact with the blade, so that larger pressure/pressure can not be generated on the blade, and the service life of the blade is prolonged.
(4) The clamp body of the blade clamping device is formed, so that the combined assembly error does not exist, and the blade clamping device is compact in structure and convenient to install.
(5) The invention provides cutters with adjustable cutting angles, which comprise the blade clamping device, and the cutters comprise angle adjusting components and cutter supporting rods, so that the rolling angles and the pitching angles of the cutters can be accurately adjusted, and the angle adjusting components are simple in structure and easy to adjust.
