[0030] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] like Figures 1 to 8As shown, the present invention provides a clamping device, comprising: a mounting seat 1, the mounting seat 1 comprises a support plate 2, a connecting rod 3 and a cover plate 4 which are sequentially connected from bottom to top to enclose a connected mounting cavity 5 and an opening portion 6, the opening portion 6 is located on the cover plate 4 for inserting one end of a workpiece; a clamping mechanism 8, the clamping mechanism 8 is movably arranged in the mounting cavity 5 for clamping or releasing the workpiece; a base 9, the base 9 is arranged below the mounting seat 1, the base 9 comprises a bottom plate 10 and a turntable 11 which are sequentially arranged from bottom to top and are rotatably connected relative to each other, the turntable 11 is rotatably connected to the bottom plate 10, and the bottom plate 10 is used to be connected to a position to be installed; a lifting mechanism 12, the two ends of the lifting mechanism 12 are respectively connected to the support plate 2 and the turntable 11, so that the clamping mechanism 8 and the workpiece can move up and down relative to the base 9.

[0032] In this way, the clamping device of the present invention can quickly clamp or release the workpiece, and flexibly adjust the height and angle of the workpiece in three-dimensional space, effectively reducing the time required to adjust the position of the workpiece. It is suitable for scenarios that require precise alignment and multi-angle testing, and reduces errors in human operation, such as experimental testing, precision machining, automated assembly lines, etc., greatly improving the flexibility of the test, processing accuracy and production efficiency. It is particularly suitable for installation in wind tunnel equipment to clamp and adjust the anemometer, solving the problem in the prior art that the mounting base of the wind tunnel equipment cannot adjust the installation height and angle of the anemometer.

[0033] Specifically, there are multiple connecting rods 3 , and the multiple connecting rods 3 are arranged between the support plate 2 and the cover plate 4 at intervals.

[0034] like Figures 3 to 8 As shown, the clamping mechanism 8 also includes: an inner gear ring 13, which is rotatably arranged in the installation cavity 5 around its own center line, and the center line of the inner gear ring 13 is perpendicular to the support plate 2; a guide circular plate 7, which is installed on the support plate 2 and located in the inner gear ring 13, and the guide circular plate 7 is slidably matched with the inner gear ring 13 to guide the rotation of the inner gear ring 13; a plurality of clamping parts 14, which are arranged in the inner gear ring 13 around the center line of the inner gear ring 13 and are located on the guide circular plate 7 to form a clamping space 15 for clamping workpieces; a plurality of guide parts 16, which are arranged one by one corresponding to the plurality of clamping parts 14, and each guide part 16 is installed on the guide circular plate 7 and / or the cover plate 4 and is slidably connected with the corresponding clamping part 14 to guide the movement of the corresponding clamping part 14.

[0035] Under the precise control of the inner gear ring 13, the clamping component 14 can quickly and accurately clamp, release and adjust the position of the workpiece, greatly shortening the workpiece replacement time and improving work efficiency. Especially in a production environment with multiple varieties and small batches, this fast and accurate workpiece clamping capability is particularly important, which can reduce equipment downtime, improve equipment utilization and reduce production costs.

[0036] In addition, the provision of the guide circular plate 7 and the guide component 16 ensures the smooth movement of the inner gear ring 13 and the clamping component 14, avoids shaking and deviation during the clamping process, and further improves the processing accuracy.

[0037] like Figures 3 to 8 As shown, the clamping component 14 includes: a gear 17, which is arranged in the inner gear ring 13 and meshes with the inner gear ring 13; a rack 18, which is located on the side of the gear 17 close to the center line of the inner gear ring 13 and meshes with the gear 17, and the extension direction of the rack 18 is parallel to the support plate 2 and does not intersect with the center line of the inner gear ring 13; a clamping block 19, which is connected to the rack 18 and is at least partially located on the side of the rack 18 close to the center line of the inner gear ring 13 to form a clamping space 15, and the surface of the clamping block 19 for forming the clamping space 15 is a clamping bevel 20, and the plane where the clamping bevel 20 is located is perpendicular to the support plate 2 and does not intersect with the center line of the inner gear ring 13; wherein the angle between the clamping bevel 20 and the rack 18 is an acute angle.

[0038] In this way, through the precise meshing of the gear 17 and the rack 18, precise control of the minute displacement of the clamping block 19 can be achieved, which is particularly important for wind tunnel testing.

[0039] Specifically, the clamping block 19 is a quadrangular prism with a right-angled trapezoidal cross section. The right-angled waist of the two waists of the right-angled trapezoid is parallel to and connected to the rack 18 , and the inclined waist of the two waists of the right-angled trapezoid is used to form the clamping slope 20 .

[0040] like Figures 3 to 8 As shown, the clamping component 14 includes a buffer pad 21, which is arranged on the clamping block 19 and is located on the side of the clamping block 19 close to the clamping space 15; and / or the guiding component 16 includes a first guide rail 22, which is arranged on the guiding circular plate 7 and is parallel to the rack 18 of the corresponding clamping component 14, and the clamping block 19 is provided with a first slide groove 23 that is slidably connected to the first guide rail 22; and / or the guiding component 16 includes a second guide rail 24, which is arranged on the cover plate 4 and is parallel to the rack 18 of the corresponding clamping component 14, and the clamping block 19 is provided with a second slide groove 25 that is slidably connected to the second guide rail 24.

[0041] Specifically, the design of the buffer pad 21 ensures the contact area between the clamping block 19 and the workpiece, improves the stability of the clamping, effectively prevents the workpiece from moving slightly during the processing, and further ensures the test accuracy.

[0042] Preferably, the buffer pad 21 is a rubber pad.

[0043] Further preferably, the material of the buffer pad 21 is nitrile rubber.

[0044] like Figures 3 to 8 As shown, there are four clamping components 14, which are installed on the guide circular plate 7 in a rectangular shape and are movably arranged in a direction close to or away from the center line of the guide circular plate 7 to clamp or release the workpiece.

[0045] Correspondingly, the number of guide components 16 is also four, and the first guide rails 22 of the four guide components 16 are rectangularly arranged on the upper surface of the guide circular plate 7, and the second guide rails 24 of the four guide components 16 are rectangularly installed on the lower surface of the cover plate 4; wherein, the first guide rail 22 and the second guide rail 24 of each guide component 16 are relatively arranged to jointly play a guiding and limiting role in the movement of the rack 18 and the clamping block 19 of the corresponding clamping component 14.

[0046] When the inner gear ring 13 rotates, it can drive the clamping blocks 19 of the four clamping components 14 to move in the direction close to or away from the center line of the guide circular plate 7 under the guiding and limiting action of the four guide components 16, so that the clamping space 15 surrounded by one side of the center line of the guide circular plate 7 of the clamping blocks 19 of the four clamping components 14 can be adjusted to achieve clamping or loosening of the workpiece such as a wind meter.

[0047] like Figures 1 to 3 As shown, the clamping device includes: a first driving mechanism 26, which is arranged on the support plate 2 and is drivingly connected to the inner gear ring 13 to drive the inner gear ring 13 to rotate; and / or a second driving mechanism 33, which is arranged on the base plate 10 and is drivingly connected to the turntable 11 to drive the turntable 11 to rotate.

[0048] The clamping device of the present invention is driven smoothly and accurately by the first drive mechanism 26, which is crucial for wind tunnel testing. It can ensure the accuracy of the anemometer when adjusting small angles, and improve the test accuracy and quality. In addition, the introduction of the second drive mechanism 33 provides the workpiece with a full range of angle adjustment capabilities, which is very beneficial for scenes that require operations from multiple angles, such as the processing of complex curved surfaces and the assembly of polyhedrons. It can reduce the number of repositioning of the workpiece, improve test efficiency, reduce dependence on the technical requirements of the operator, and improve the degree of automation of the test.

[0049] like Figures 1 to 3As shown, the first driving mechanism 26 includes a first motor 27 and a first transmission assembly 28. The first motor 27 is arranged on the support plate 2 and is drivingly connected to the first transmission assembly 28. The first transmission assembly 28 is connected to the inner gear ring 13. The first motor 27 drives the inner gear ring 13 to rotate through the first transmission assembly 28.

[0050] Specifically, the combination of the first motor 27 and the first transmission assembly 28 not only ensures the high precision of the rotation of the inner ring 13, but also reduces the complexity and cost of equipment maintenance by simplifying the structure. This design can significantly improve test efficiency and stability and reduce test pauses caused by equipment maintenance.

[0051] like Figures 1 to 3 As shown, the first transmission assembly 28 includes a first worm 29 and a first worm outer gear ring 30 meshing with each other, the rotating shaft of the first motor 27 is connected to the first worm 29 , and the first worm outer gear ring 30 is arranged on the outer circumferential surface of the inner gear ring 13 .

[0052] In this way, the self-locking characteristics of the worm transmission between the first worm 29 and the first worm outer gear ring 30 provide additional safety protection for the clamping device, which can effectively prevent the accidental movement of the workpiece during the processing, reduce the test errors and equipment damage caused by the displacement of the workpiece, ensure the safety of the test process, improve the test efficiency, and reduce the test risk.

[0053] like Figures 1 to 3 As shown, the second driving mechanism 33 includes a second motor 34 and a second transmission assembly 35. The second motor 34 is arranged on the base plate 10 and is drivingly connected to the second transmission assembly 35. The second transmission assembly 35 is connected to the turntable 11. The second motor 34 drives the turntable 11 to rotate through the second transmission assembly 35.

[0054] Specifically, the combination of the second motor 34 and the second transmission assembly 35 provides the workpiece with the ability of continuous angle adjustment, which is crucial for wind tunnel testing scenarios. It can ensure the continuity and stability of the workpiece during the testing process, reduce test errors caused by discontinuous workpiece angle adjustment, and improve test quality and efficiency.

[0055] like Figures 1 to 3 As shown, the second transmission assembly 35 includes a second worm 36 and a second worm outer gear ring 37 meshing with each other, the rotating shaft of the second motor 34 is connected to the second worm 36 , and the second worm outer gear ring 37 is arranged on the outer circumferential surface of the rotating disk 11 .

[0056] In this way, the high torque transmission capability of the second worm 36 and the second worm outer gear ring 37 provides strong support for wind tunnel testing, effectively preventing adjustment errors of the rotation angle of the workpiece, and plays an important role in improving test quality and safety.

[0057] like Figures 1 to 3 As shown, the lifting mechanism 12 includes a drive cylinder 31 and a sleeve 32, one end of the piston rod of the drive cylinder 31 is connected to the sleeve 32, the shell of the drive cylinder 31 is connected to one of the support plate 2 and the turntable 11, and the sleeve 32 is connected to the other of the support plate 2 and the turntable 11.

[0058] In this way, the combination of the drive cylinder 31 and the sleeve 32 not only provides a fast and smooth lifting capability, but also achieves fine adjustment of the workpiece height through precise control, reduces the number of repositioning of the workpiece, and improves test continuity and efficiency.

[0059] The use process of the clamping device of the present invention is as follows:

[0060] (1) First, place the bottom of the anemometer into the installation cavity 5 through the opening 6, and then start the first motor 27 of the second transmission assembly 35 to drive the first worm 29 to drive the first worm outer gear ring 30 to rotate, so that the first worm outer gear ring 30 drives the inner gear ring 13 to rotate, so that the clamping blocks 19 of the four clamping components 14 are driven by the inner gear ring 13 to move in a direction close to or away from the center line of the guide circular plate 7 under the guiding and limiting action of the four guide components 16, so as to clamp or release the anemometer.

[0061] (2) By controlling the extension and retraction of the piston rod of the driving cylinder 31, the mounting base 1 and the clamping mechanism 8 thereon can be driven to move up and down to adjust the height of the anemometer.

[0062] (3) The second motor 34 of the second driving mechanism 33 is controlled to rotate, so as to drive the second worm 36 to drive the second worm outer gear ring 37 to rotate, so that the second worm outer gear ring 37 drives the turntable 11 to rotate, and the lifting mechanism 12 located thereon, as well as the mounting base 1, the clamping mechanism 8 and the anemometer are driven to rotate through the turntable 11 to adjust the height of the anemometer.
