Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0061] This application discloses a viewing fixture with height and angle adjustment functions.

[0062] Please see Figure 1 An embodiment of a viewing fixture with height and angle adjustment functions provided in this application includes:

[0063] The base 1, height adjustment device 3, angle adjustment device 2, and support bracket 4.

[0064] The support bracket 4 is used to support the workpiece to be observed; the height adjustment device 3 is installed on the base 1 and connected to the support bracket 4, and is used to adjust the displacement of the support bracket 4 in the Z-axis direction 5.

[0065] Angle adjustment device 2 is installed on base 1 and connected to support bracket 4, and is used to adjust the rotation angle of support bracket 4; the rotation center line of support bracket 4 is parallel to the Z-axis direction 5.

[0066] The viewing fixture with height and angle adjustment functions designed in this application has the following beneficial effects:

[0067] By combining the height adjustment device 3 and the angle adjustment device 2, operators can flexibly adjust the height and rotation angle of the support bracket 4 according to specific observation needs, eliminating the need for repeated manual handling or adjustment of the workpiece's position and posture. This significantly reduces operating time costs and labor intensity, and improves overall work efficiency.

[0068] The above is Embodiment 1 of a viewing fixture with height and angle adjustment functions provided in this application. The following is Embodiment 2 of a viewing fixture with height and angle adjustment functions provided in this application. Please refer to the following for details. Figures 1 to 7 .

[0069] Based on the solution of Embodiment 1 above:

[0070] Furthermore, such as Figure 1 As shown, the height adjustment device 3 is installed on the angle adjustment device 2; the support bracket 4 is installed on the height adjustment device 3; the angle adjustment device 2 adjusts the rotation angle of the support bracket 4 by driving the height adjustment device 3 to rotate. It can be understood that the height adjustment device 3 and the angle adjustment device 2 are arranged in a layered layout, which makes the tooling more efficient in space utilization, reduces the occupied area, and also facilitates maintenance and repair. When it is necessary to adjust the height of the support bracket 4, only the height adjustment device 3 needs to be operated without affecting the state of the angle adjustment device 2; similarly, adjusting the angle will not interfere with the height.

[0071] Alternatively, the height adjustment device 3 can be positioned at the bottom and the angle adjustment device 2 at the top; there are no specific restrictions.

[0072] Furthermore, such as Figure 2 As shown, for the design of base 1, it can be a flat structure with one corner removed from each side to form a cross shape. The material is a high-strength metal, such as aluminum alloy plate. The required holes and flat surface are machined by CNC milling to ensure that the flatness is ≤0.1mm.

[0073] The base 1 is provided with platform fixing holes 11 for fixed connection with the optical platform, so that the optical platform can be fastened to the base 1 by screws / bolts. The number and distribution of the platform fixing holes 11 can be designed to vary according to actual needs and are not limited.

[0074] Taking the angle adjustment device 2 distributed at the bottom as an example, the base 1 is also provided with an angle fixing hole 12 for fixed connection with the angle adjustment device 2, so that the angle adjustment device 2 can be fastened to the base 1 by screws and bolts. It can be understood that both the platform fixing hole 11 and the angle fixing hole 12 can be threaded holes.

[0075] Furthermore, such as Figure 3As shown, the angle adjustment device 2 includes a first connecting seat 21, a turntable 22, and a rotating assembly (not shown in the figure).

[0076] The turntable 22 is rotatably mounted on the first connecting seat 21 via a rotating assembly. The first connecting seat 21 is fixedly connected to the base 1, and the height adjustment device 3 is fixedly connected to the turntable 22.

[0077] This design allows the turntable 22 to rotate flexibly on the first connecting seat 21, driving the height adjustment device 3 to rotate, which in turn drives the support bracket 4 to rotate, thus achieving angle adjustment. The reasonable arrangement of the rotating components ensures the stability and accuracy of the turntable 22's rotation. Moreover, the fixed connection between the first connecting seat 21 and the base 1 enhances the structural stability of the entire fixture, ensuring that the fixture as a whole will not wobble or shift when adjusting the angle of the support bracket 4.

[0078] Furthermore, regarding the design of the rotating assembly, including the rotating shaft and bearing, the top of the first connecting seat 21 has a mounting groove, in which the bearing is fixed. The rotating shaft is fixed to the bottom of the turntable 22 and is inserted into and mates with the bearing to achieve 360° angle adjustment. The bearing can be a thrust bearing, which effectively withstands axial force, ensuring the smoothness of the rotating shaft during rotation and further improving the stability of the turntable 22's rotation. The rotating shaft can be made of stainless steel, and the mating area with the bearing is precision machined to Ra0.8μm to ensure smooth rotation.

[0079] The first connecting seat 21 has scale lines around the turntable 22, or the turntable 22 itself has scale lines. The scale lines design allows operators to precisely control the rotation angle of the support bracket 4, improving the precision and accuracy of angle adjustment. Operators can intuitively understand the rotation angle of the turntable 22 according to the scale lines, thus better meeting observation needs.

[0080] Furthermore, the angle adjustment device 2 also includes a locking element (not shown in the figure); the turntable 22 has a locking hole through which the locking element moves and engages with the locking element's thread; one end of the locking element passing downward through the turntable 22 can contact and abut against the first connecting seat 21 to lock the rotation position of the turntable 22. The locking element ensures that after the support bracket 4 is adjusted to a suitable rotation angle, the position of the turntable 22 can be fixed, preventing the turntable 22 from rotating due to accidental contact during observation, thus ensuring the stability and accuracy of the observation. When the angle needs to be adjusted again, simply loosen the locking element, and the turntable 22 can continue to rotate. The locking element can be a screw or bolt, and there is no specific limitation.

[0081] The scale lines, in conjunction with the locking mechanism, enable precise angle positioning (accuracy improved to over 0.5°).

[0082] The rotation adjustment of turntable 22 can be driven by a worm gear. For example, a worm gear can be rotatably installed on the base 1 or the first connecting seat 21, and worm gear teeth are designed around the turntable 22. The worm gear teeth mesh with the worm gear, and the turntable 22 can be rotated by rotating the worm gear.

[0083] A protective cover can be designed on the outside of the worm gear to cover the mating position between the worm gear and the turntable 22. The locking element can be installed on the protective cover and further lock the movement of the turntable 22 by contacting and abutting against the worm gear (the worm gear mating itself has a self-locking characteristic). Alternatively, the use of the locking element can be eliminated.

[0084] Furthermore, such as Figure 1 As shown in Figure 4, the height adjustment device 3 includes a second connecting seat 31, a third connecting seat 32, and a height adjustment mechanism; the second connecting seat 31 and the third connecting seat 32 are flat plate structures with a certain thickness, and there are no specific limitations.

[0085] The third connecting seat 32 is positioned above the second connecting seat 31; a height adjustment mechanism is connected between the second connecting seat 31 and the third connecting seat 32, used to adjust the distance between the third connecting seat 32 and the second connecting seat 31 in the Z-axis direction 5; the second connecting seat 31 is fixedly connected to the angle adjustment device 2; and the bearing bracket 4 is fixedly connected to the third connecting seat 32. This design allows the height adjustment mechanism to stably adjust the distance between the third connecting seat 32 and the second connecting seat 31, thereby achieving height adjustment of the bearing bracket 4 in the Z-axis direction 5. The reasonable arrangement of the height adjustment mechanism ensures the accuracy and stability of height adjustment, enabling operators to accurately adjust the height of the bearing bracket 4 according to actual needs. Moreover, the fixed connection between the second connecting seat 31 and the angle adjustment device 2, as well as the fixed connection between the bearing bracket 4 and the third connecting seat 32, enhances the coherence and stability of the entire tooling structure, ensuring that the tooling as a whole will not shake or shift when adjusting the height.

[0086] Furthermore, the height adjustment mechanism design includes a guide assembly and an adjustment assembly; the third connecting seat 32 is slidably connected to the second connecting seat 31 in the Z-axis direction 5 via the guide assembly; the adjustment assembly is connected between the third connecting seat 32 and the second connecting seat 31 to adjust the sliding displacement of the third connecting seat 32 relative to the second connecting seat 31.

[0087] The guide component provides stable guidance for the sliding of the third connecting seat 32 in the Z-axis direction 5, ensuring the linearity and accuracy of the height adjustment process. The adjustment component precisely controls the sliding displacement of the third connecting seat 32, thereby achieving precise adjustment of the height of the support bracket 4. The adjustment component acts as a displacement driver. Together with the guide component, the adjustment component not only achieves precise height adjustment of the support bracket 4 in the Z-axis direction 5, but also possesses good stability and durability, meeting the needs of different working scenarios and providing a more convenient and efficient operating experience for observation work.

[0088] Furthermore, such as Figure 5 as well as Figure 6 As shown, the guide assembly design includes a fixing block 34 and a sliding groove 35. The sliding groove 35 is formed along the Z-axis direction 5 on the third connecting seat 32. The fixing block 34 is fixed on the second connecting seat 31 and has a protrusion 341 that extends into the sliding groove 35 and slides in cooperation with the sliding groove 35 in the Z-axis direction 5. This design allows the third connecting seat 32 to slide smoothly along the protrusion 341 on the fixing block 34 within the sliding groove 35, ensuring the smoothness and stability of the height adjustment process. The high precision of the fit between the protrusion 341 and the sliding groove 35 effectively reduces shaking and deviation during the sliding process, further improving the accuracy of height adjustment. It should be noted that... Figure 5 The groove 35 in the drawing is simplified, so it looks like a round hole, but it is actually a hole with a certain length.

[0089] The number of fixing blocks 34 can be varied according to actual needs, such as setting two or four. The number of sliding grooves 35 is the same as the number of fixing blocks 34. The distribution can be evenly distributed around the second connecting seat 31 or distributed on one side.

[0090] In addition to the design of the fixing block 34 and the slide 35, the guide assembly may also include at least two telescopic rods, which are connected and fixed between the third connecting seat 32 and the second connecting seat 31.

[0091] like Figure 5 as well as Figure 6 As shown, the design of the adjustment component includes a height adjustment part 36 and a nut (not shown in the figure); the nut is embedded in the second connecting seat 31; the height adjustment part 36 is a screw, one end of which extends into the second connecting seat 31 and is threadedly engaged with the nut; the other end of the height adjustment part 36 can contact and abut against the base 1 of the third connecting seat 32 or be rotatably and fixedly connected to the third connecting seat 32 (rotatable and fixedly connected means that the other end of the height adjustment part 36 can rotate relative to the third connecting seat 32 without affecting its own rotation, while it is fixedly connected to the third connecting seat 32 in the Z-axis direction 5, so as to drive the third connecting seat 32 to move up and down in the Z-axis direction 5).

[0092] When the height adjustment component 36 is rotated, due to the threaded engagement between the nut and the height adjustment component 36, the component 36 will move axially within the nut. This axial movement of the height adjustment component 36 will cause the third connecting seat 32 to displace relative to the second connecting seat 31 in the Z-axis direction 5, thereby adjusting the height of the support bracket 4. This adjustment method offers high precision; the operator can precisely control the sliding displacement of the third connecting seat 32 by controlling the number of rotations or the angle of the height adjustment component 36, thus accurately adjusting the height of the support bracket 4. Furthermore, this threaded engagement adjustment method has a self-locking function, maintaining the current position after adjustment to the appropriate height, preventing easy changes due to external forces and ensuring the stability of the support bracket 4's height. In addition, the structure of the height adjustment component 36 and the nut is simple, easy to manufacture and maintain, reducing the production cost and maintenance difficulty of the tooling. Specifically, the height adjustment component 36 can be a trapezoidal threaded steel rod (1mm pitch), nickel-plated for rust prevention, with an adjustment height range of 0mm-2000mm, without specific limitations.

[0093] The adjusting assembly can also be a scissor-type lifting assembly, including a scissor frame and a drive screw. The top connecting end of the scissor frame is hinged to the third connecting seat 32, while the bottom connecting end is slidably connected to the second connecting seat 31. The drive screw passes through the bottom connecting end and is threadedly connected to it. By rotating the drive screw, the connecting ends on both sides at the bottom can slide closer or further apart, thereby changing the height of the scissor frame and thus driving the third connecting seat 32 to rise or fall. If a scissor-type lifting assembly is designed, the guide assembly can be omitted.

[0094] Furthermore, such as Figure 7 As shown, the support bracket 4 includes a support base 41 and a column 42; the column 42 is arranged parallel to the Z-axis direction 5; the support base 41 is vertically connected to the bottom of the column 42; the support base 41 is fixed to the third connecting seat 32 by screws / bolts.

[0095] The top surface of the support base 41 is provided with an anti-slip structure, which can be a frosted structure or the like, to increase friction and prevent the workpiece to be observed from sliding.

[0096] The column 42 is provided with a reserved mounting hole 43 for fixing the workpiece to be observed.

[0097] The angle adjustment device 2 can also be designed to be electrically driven; for example, a drive motor can be added and connected to the rotating shaft to realize electric rotation control. The drive motor can be a flat motor, or the drive motor can be connected to the turntable 22 through a transmission component to drive the turntable 22 to rotate. For example, the outer circumference of the turntable 22 is provided with transmission teeth, and the output shaft of the drive motor is fixed with a drive gear that meshes with the transmission teeth.

[0098] The height adjustment device 3 can also be designed to be electrically driven; for example, the height adjustment component can be designed as an electric telescopic rod or a telescopic cylinder, etc., and there are no specific restrictions.

[0099] The above provides a detailed description of a viewing fixture with height and angle adjustment functions provided in this application. For those skilled in the art, based on the ideas of the embodiments of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
