Description

Technical Field

[0001] This utility model relates to the field of biological slicing equipment technology, and in particular to a blade angle adjustment device, a blade module and a slicing device. Background Technology

[0002] Highly sharp cutting tools are essential for obtaining precise biological sections at the nanometer to micrometer scale. With a cutting edge radius of only tens to hundreds of nanometers, they can produce mirror-like smooth surfaces in a single cut, significantly reducing the difficulty of subsequent optical, mass spectrometry, sequencing, and pathological studies. However, these tools are expensive, and even slight deviations in the installation angle can lead to a decrease in section quality and accelerate blade wear or chipping. Furthermore, when section thickness, speed, or sample material changes, adaptive fine-tuning of the cutting tool angle is necessary.

[0003] During cutting, the pitch angle and roll angle have a significant impact on the slice quality (see...). Figure 6 (As shown). Inaccurate pitch angle can easily cause abnormal noise, accelerate wear, and even cause chipping of the blade tip; inaccurate roll angle can leave blade edges and scratches on the sample surface, reducing the mirror effect. Current angle adjustment methods are relatively primitive: pitch angle is adjusted by rotating the blade by hand, comparing with a protractor, and then tightening the screw; roll angle is adjusted by inserting a 0.01mm to 0.1mm precision shim under the mounting surface, repeatedly cutting, adding or removing shims until the scratches disappear. The whole process relies on experience, is inefficient, and repeated disassembly and assembly can easily introduce errors, making it difficult to meet the sub-micron angular accuracy requirements of high-sharpness blades. In addition, the blade tip position changes every time the pitch angle or roll angle parameters are adjusted, requiring readjustment of the relative position of the sample and the blade tip, which is complicated and prone to introducing secondary errors.

[0004] It is evident that in existing technologies, manual angle adjustment methods have low precision and poor efficiency, and the tool tip moves immediately after adjustment, requiring repeated sample alignment, which makes it difficult to meet the submicron level stable cutting requirements of high-sharpness tools.

[0036] The following is combined Figures 1 to 5 This invention describes the tool angle adjustment device, tool module, and slicing device provided by this utility model.

[0037] See Figures 1 to 5 As shown, the tool angle adjustment device provided in this embodiment of the present invention includes: a mounting base 100, a roll angle adjustment component 200, a pitch angle adjustment component 300, and a tool mounting component 400.

[0038] The roll angle adjustment assembly 200 includes a first fixed base 210, a first swing base 220, and a first adjusting screw 230. The first fixed base 210 is connected to the mounting base 100. The first swing base 220 slides along a first arc-shaped trajectory with the first fixed base 210. A first transmission tooth groove 221 is provided on the first swing base 220 along the first arc-shaped trajectory, and the first adjusting screw 230 engages with the first transmission tooth groove 221. The pitch angle adjustment assembly 300 includes a second fixed base 310, a second swing base 320, and... The second adjusting screw 330 and the second fixed seat 310 are connected to the first swing seat 220. The second swing seat 320 and the second fixed seat 310 cooperate along the second arc-shaped trajectory. The second swing seat 320 is provided with a second transmission tooth groove 321 along the second arc-shaped trajectory. The second adjusting screw 330 cooperates with the second transmission tooth groove 321. The plane where the first arc-shaped trajectory is located is perpendicular to the plane where the second arc-shaped trajectory is located. The tool mounting part 400 is connected to the second swing seat 320 and is used to mount the tool 700.

[0039] The rotation axis center of the first arc-shaped trajectory and the rotation axis center of the second arc-shaped trajectory are both configured to be located at the tip center of the tool 700.

[0040] The tool angle adjustment device provided by this utility model, by setting the roll angle adjustment component 200 and the pitch angle adjustment component 300, can independently adjust the roll angle and / or pitch angle of the tool 700 located on the tool mounting part 400 using the first adjustment screw 230 and the second adjustment screw 330 respectively. This can significantly improve the adjustment efficiency and adjustment accuracy. Furthermore, since the rotation axis center of the first arc trajectory and the rotation axis center of the second arc trajectory are both configured to be located at the tool tip center point of the tool 700, the tool tip center point of the tool 700 is always in the initial position during the adjustment of the roll angle and / or pitch angle of the tool 700. There is no need to re-set the tool, and efficient adjustment can be achieved by testing after machining, and then adjusting and testing again.

[0041] It is understood that the tool angle adjustment device provided by this utility model can also realize the individual adjustment of roll angle or pitch angle. When only the roll angle needs to be adjusted, rotating the first adjusting screw 230 will cause the tool 700 to rotate around the tool tip while the pitch angle remains unchanged; conversely, rotating only the second adjusting screw 330 will cause the tool 700 to pitch in the vertical plane while the roll angle remains unchanged.

[0042] Specifically, the mounting base 100 is used to fix the entire angle adjustment device to the slicing device and serves as a rigid reference for the roll angle and pitch angle adjustment assembly 300, ensuring zero displacement of the blade tip during adjustment.

[0043] The roll angle adjustment assembly 200 drives the cutting tool 700 to rotate around its tip centerline, thereby finely adjusting the roll angle of the cutting tool 700. This assembly, through the meshing of the first adjusting screw 230 and the first transmission toothed groove 221, drives the first swing seat 220 to slide along a first arc-shaped trajectory, achieving angle adjustment of the cutting tool 700 in the roll direction. Since the center of rotation of the first arc-shaped trajectory is configured to be located at the tip center point of the cutting tool 700, the tip of the cutting tool 700 remains in its initial position throughout the entire roll angle adjustment process, without spatial displacement, thus avoiding the tip offset problem caused by angle changes in traditional adjustment methods.

[0044] The pitch angle adjustment component 300 drives the tool 700 to pitch around its tip center point within a second arc-shaped trajectory perpendicular to the roll angle plane, thereby enabling micron-level fine adjustment of the tool 700's rake / relief angle (pitch angle). This component uses the first swing seat 220 of the roll angle adjustment component 200 as a rigid reference. Through the meshing of the second adjusting screw 330 and the second transmission toothed groove 321, the rotational motion of the screw is converted into precise oscillation of the second swing seat 320 along the arc. Since the rotation axis center of the second arc-shaped trajectory also coincides with the tool tip center point, the tool tip spatial coordinates remain at zero displacement during pitch angle adjustment, eliminating the cumbersome steps of tool setting or coordinate compensation.

[0045] The tool mount 400 is fixedly connected to the second swing seat 320 and provides a repeatable clamping interface for the tool 700. The tool mount 400 ensures that the tool 700 remains rigidly synchronized with the second swing seat 320 throughout the entire process of roll and pitch angle adjustment. It also enables quick tool change and micron-level radial / axial positioning accuracy, thereby accurately transmitting the minute angular displacement of the angle adjustment component to the cutting edge. This ensures that the center point of the tool tip is always located at the intersection of the biaxial orthogonal circular arc trajectory, ultimately achieving high-precision angle adjustment with "zero displacement and no tool setting required".

[0046] When adjusting the roll angle and pitch angle of the tool 700, the roll angle adjustment component 200 drives the tool 700 to rotate around the tool tip axis through the first lead screw-tooth groove pair, and the pitch angle adjustment component 300 drives the tool 700 to swing in the vertical plane through the second lead screw-tooth groove pair. The superposition of the two can realize the linkage fine adjustment of the theoretical zero displacement of the tool tip spatial coordinates (X / Y / Z). Throughout the process, the tool tip is always located at the initial cutting point, and there is no need to re-set the tool or compensate the coordinate system. After the adjustment is completed, a closed-loop iteration of trial cutting-measurement-fine adjustment can be directly performed, which significantly shortens the process preparation time and improves the consistency of the finished product dimensions.

[0047] See Figure 1 and Figure 2As shown, according to some embodiments of the present invention, a first sliding engagement mechanism is provided between the first fixed seat 210 and the first swing seat 220. The first sliding engagement mechanism includes a first V-shaped guide rail 211 and a first V-shaped guide groove 222. One of the first V-shaped guide rail 211 and the first V-shaped guide groove 222 is located in the first fixed seat 210, and the other is located in the first swing seat 220. The first V-shaped guide rail 211 and the first V-shaped guide groove 222 are slidably engaged. A first transmission tooth groove 221 is located in the first V-shaped guide groove 222. A second sliding engagement mechanism is provided between the second fixed seat 310 and the second swing seat 320. The second sliding engagement mechanism includes a second V-shaped guide rail 311 and a second V-shaped guide groove 322. One of the second V-shaped guide rail 311 and the second V-shaped guide groove 322 is located in the second fixed seat 310, and the other is located in the second swing seat 320. The second V-shaped guide rail 311 and the second V-shaped guide groove 322 are slidably engaged. A second transmission tooth groove 321 is located in the second V-shaped guide groove 322.

[0048] By setting the first sliding engagement mechanism between the first fixed seat 210 and the first swing seat 220 and the second sliding engagement mechanism between the second fixed seat 310 and the second swing seat 320 as V-shaped guide rails and V-shaped guide grooves, the first swing seat 220 and the second swing seat 320 can be provided with stable support and fixation. During adjustment, the first swing seat 220 and / or the second swing seat 320 can achieve pure rolling sliding without gaps or creep under the guidance of the V-shaped guide rails and V-shaped guide grooves, ensuring that the blade tip position is always in a high-precision stable state throughout the adjustment process, thus taking into account both the high rigidity support and high-precision adjustment requirements.

[0049] It should be noted that one of the first V-shaped guide rail 211 and the first V-shaped guide groove 222 is located in the first fixed seat 210, and the other is located in the first swing seat 220. Similarly, one of the second V-shaped guide rail 311 and the second V-shaped guide groove 322 is located in the second fixed seat 310, and the other is located in the second swing seat 320. This indicates that the "rail stationary, groove moving" or "rail moving, groove stationary" configuration can be flexibly selected according to the specific structural space, load direction, and process inheritance requirements, without changing the gapless guiding principle of the V-shaped guide rail and the V-shaped guide groove. Thus, under the same performance premise of "zero tool tip drift and submicron-level angular accuracy", the maximum modularity and compatibility of design, manufacturing, and maintenance can be achieved.

[0050] See Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, a first V-shaped guide rail 211 is disposed on a first fixed seat 210, a first V-shaped guide groove 222 is disposed on a first swing seat 220, a second V-shaped guide rail 311 is disposed on a second fixed seat 310, and a second V-shaped guide groove 322 is disposed on a second swing seat 320.

[0051] By placing the first V-shaped guide rail 211 on the first fixed base 210 and the first V-shaped guide groove 222 on the first swing base 220, and placing the second V-shaped guide rail 311 on the second fixed base 310 and the second V-shaped guide groove 322 on the second swing base 320, a "rail stationary, groove moving" configuration is formed, integrating the guide rail and the fixed base, enhancing structural rigidity and simplifying the assembly process. Simultaneously, the guide groove moves with the swing base, maintaining close contact with the guide rail, achieving a gapless and highly stable guiding effect. This is beneficial for improving the accuracy and reliability of the tool 700 angle adjustment, meeting the sub-micron level angle control requirements of the high-sharpness tool 700.

[0052] In some embodiments, the first V-shaped guide rail 211 may also be a ball / roller guide rail or a crossed roller bearing guide rail (not shown in the figure). In this case, the first V-shaped guide groove 222 needs to be configured as a guide groove form corresponding to the ball / roller guide rail or the crossed roller bearing guide rail. Similarly, the second V-shaped guide rail 311 may also be a ball / roller guide rail or a crossed roller bearing guide rail (not shown in the figure). In this case, the second V-shaped guide groove 322 needs to be configured as a guide groove form corresponding to the ball / roller guide rail or the crossed roller bearing guide rail.

[0053] See Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, a first adjusting screw 230 is inserted through a first fixed base 210 and rotates with the first fixed base 210, with one end of the first adjusting screw 230 located outside the first fixed base 210; a second adjusting screw 330 is inserted through a second fixed base 310 and rotates with the second fixed base 310, with one end of the second adjusting screw 330 located outside the second fixed base 310.

[0054] By passing the first adjusting screw 230 through the first fixed base 210 and rotating with it, with one end exposed, and passing the second adjusting screw 330 through the second fixed base 310 and rotating with it, with one end exposed, it is convenient to manually adjust through the exposed part of the screw, or to electrically adjust by connecting an external drive component (such as a servo motor) through the exposed part of the screw.

[0055] For example, during manual adjustment, a micrometer head or handwheel can be directly installed on the exposed section of the lead screw for manual operation. Turning the lead screw adjusts the pitch or roll angle of the cutting tool 700. During electric adjustment, a small coupling can be directly clamped at the exposed end of the lead screw, and a servo motor or other drive component can be plugged in. The rotation of the lead screw changes from manual to electric, which can improve adjustment accuracy and enhance the automation level of the equipment.

[0056] See Figure 1 and Figure 2As shown, according to some embodiments of the present invention, the roll angle adjustment assembly 200 further includes a first adjustment head 240, which is disposed at the exposed end of the first adjustment screw 230; the pitch angle adjustment assembly 300 further includes a second adjustment head 340, which is disposed at the exposed end of the second adjustment screw 330.

[0057] By setting a first adjusting head 240 and a second adjusting head 340 at the exposed ends of the first adjusting screw 230 and the second adjusting screw 330 respectively, the operator can directly rotate the first adjusting screw 230 and the second adjusting screw 330 without the aid of tools, which facilitates the adjustment of the roll angle and pitch angle of the tool 700. The structure is simple and the operation is convenient.

[0058] The first adjusting head 240 and the second adjusting head 340 can be in the form of knurled handwheels or micro-heads, as long as they can meet the needs of manual operation, and there are no special restrictions on them.

[0059] See Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the tool angle adjustment device further includes: a first locking mechanism 500 and a second locking mechanism 600.

[0060] The first locking mechanism 500 is used to lock the sliding engagement mechanism of the first fixed seat 210 and the first swing seat 220; the second locking mechanism 600 is used to lock the sliding engagement mechanism of the second fixed seat 310 and the second swing seat 320.

[0061] By setting the first locking mechanism 500 and the second locking mechanism 600, the sliding engagement mechanism between the first fixed seat 210 and the first swing seat 220 and the sliding engagement mechanism between the second fixed seat 310 and the second swing seat 320 can be locked respectively, so that the first swing seat 220 and the second swing seat 320 can be locked and fixed after the adjustment is completed, so that the roll angle and pitch angle of the tool 700 can be maintained in the current state.

[0062] Furthermore, when adjusting the roll angle or pitch angle of the tool 700 individually, one of the swing seats can be released and the other swing seat can be locked using the locking mechanism, thus achieving individual adjustment of the roll angle or pitch angle. For example, when only the roll angle needs to be adjusted, the second swing seat 320 can be locked using the second locking mechanism 600, while the first locking mechanism 500 releases the first swing seat 220, and the first adjusting screw 230 can be rotated.

[0063] Both the first locking mechanism 500 and the second locking mechanism 600 can adopt various structural forms known in the prior art, such as locking screws, locking pins, etc., without any special limitation.

[0064] See Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the first locking mechanism 500 includes a first threaded locking member 510, which is threadedly connected to the first fixed seat 210 or the first swing seat 220. In the locked state, the end of the first threaded locking member 510 abuts against the sliding connection position of the first fixed seat 210 and the first swing seat 220. The second locking mechanism 600 includes a second threaded locking member 610, which is threadedly connected to the second fixed seat 310 or the second swing seat 320. In the locked state, the end of the second threaded locking member 610 abuts against the sliding connection position of the second fixed seat 310 and the second swing seat 320.

[0065] By configuring both the first locking mechanism 500 and the second locking mechanism 600 as threaded locking components, locking is achieved simply by rotating the threaded locking component until its end abuts against the sliding connection between the fixed seat and the swing seat. This design is simple in structure and easy to operate. Unlocking is achieved by rotating the threaded locking component in the opposite direction.

[0066] According to some embodiments of the present invention, the tool angle adjustment device further includes: a first drive motor (not shown in the figure) and a second drive motor (not shown in the figure).

[0067] The drive motor is connected to the first adjusting screw 230 to drive the first adjusting screw 230 to rotate; the drive motor is also connected to the second adjusting screw 330 to drive the second adjusting screw 330 to rotate.

[0068] By connecting the first drive motor to the first adjusting screw 230 and the second drive motor to the second adjusting screw 330 respectively, the "manual turning" can be upgraded to "electric drive": the motors can receive pulses to enable the cutter 700 to complete micron-level angular steps, realizing program control or closed-loop feedback of roll angle and pitch angle. Furthermore, the two motors operate independently without affecting each other, and can be zeroed with one key and recalled from historical angles with one key, meeting the requirements of automated production lines for "unattended operation and reliable repeatability".

[0069] Both the first and second drive motors are preferably servo motors, which can read the angle encoder feedback in real time and achieve μm-level position adjustment.

[0070] The tool module provided by this utility model is described below. The tool module described below and the tool angle adjustment device described above can be referred to in correspondence.

[0071] See Figure 5 As shown, the tool module provided in this embodiment of the present invention includes: a tool angle adjustment device and a tool 700.

[0072] The cutting tool 700 is located on the cutting tool mounting part 400. The rotation axis center of the first arc-shaped trajectory and the rotation axis center of the second arc-shaped trajectory are both located at the center point of the cutting tool tip 700.

[0073] The tool module provided by this utility model, due to the adoption of the tool angle adjustment device as described in any of the above embodiments, can also independently adjust the roll angle and / or pitch angle of the tool 700 located on the tool mounting part 400 using the first adjusting screw 230 and the second adjusting screw 330 respectively. This can significantly improve the adjustment efficiency and adjustment accuracy. Furthermore, since the rotation axis center of the first arc-shaped trajectory and the rotation axis center of the second arc-shaped trajectory are both configured to be located at the center point of the tool tip of the tool 700, the center point of the tool tip of the tool 700 is always located in the initial position during the adjustment of the roll angle and / or pitch angle of the tool 700. There is no need to re-set the tool, and efficient adjustment can be achieved by testing through machining after adjustment, and then adjusting and testing again.

[0074] The cutting edge of the tool 700 can be a straight line. The tool 700 can be a hard knife such as a stainless steel knife, tungsten carbide knife, zirconium oxide knife, or diamond knife, as well as a vibrating slicing device with a blade (made of stainless steel, tungsten carbide, zirconium oxide, or diamond).

[0076] The slicing device provided in this embodiment of the utility model includes: a tool angle adjustment device or a tool module.

[0077] The slicing device provided by this utility model, by employing the tool angle adjustment device or tool module as described in any of the preceding embodiments, can also independently adjust the roll angle and / or pitch angle of the tool 700 located on the tool mounting member 400 using the first adjusting screw 230 and the second adjusting screw 330 respectively. This can significantly improve the adjustment efficiency and accuracy. Furthermore, since the rotation axis center of the first arc-shaped trajectory and the rotation axis center of the second arc-shaped trajectory are both configured to be located at the center point of the tool tip of the tool 700, the center point of the tool tip of the tool 700 is always located in the initial position during the adjustment of the roll angle and / or pitch angle of the tool 700. There is no need to re-set the tool, and efficient adjustment can be achieved by testing after adjustment and then re-adjusting and re-testing.
