Description

Technical Field

[0001] This utility model relates to the field of wind tunnel technology, specifically to a disassembly mechanism for the cone sleeve of a wind tunnel balance. Background Technology

[0002] A wind tunnel balance is a high-precision force measuring device primarily used in wind tunnel tests to measure the aerodynamic forces and torques experienced by models (such as aircraft, automobiles, and architectural models) under the influence of airflow. It is one of the core pieces of equipment for acquiring wind tunnel experimental data.

[0003] The sleeve is a key connection and positioning component in a wind tunnel balance system. Its installation and removal are routine operations in wind tunnel test preparation and maintenance. Currently, the main method used is manual hammering to remove the sleeve from the balance. This method is simple and crude, inefficient, and more importantly, it causes significant impact on the balance, especially for balances with small measuring ranges and high sensitivity. Excessive impact force can even exceed the design range, severely affecting the balance's service life. Therefore, we propose a disassembly mechanism for the sleeve of a wind tunnel balance. Utility Model Content

[0004] The purpose of this invention is to provide a disassembly mechanism for the cone sleeve of a wind tunnel balance, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a disassembly mechanism for a wind tunnel balance cone sleeve, comprising a base, two sets of support legs fixedly installed at the bottom of the base, a disassembly drive mechanism for providing a disassembly power source at the top of the base, a connecting frame fixedly installed at the top of the disassembly drive mechanism, a clamping mechanism for contacting one end of the cone sleeve fixedly installed at the top of the connecting frame, a contact squeezing mechanism for contacting and positioning one end of the cone sleeve on the clamping mechanism, and a limiting mechanism for preventing the clamping mechanism from disengaging from one end of the cone sleeve on the outside of the clamping mechanism.

[0006] Furthermore, the disassembly drive mechanism includes a first mounting plate, a drive screw, a drive motor, a slide rail, a slider, and a movable frame. Two sets of first mounting plates are fixedly mounted on the top of the base. A drive screw is rotatably connected to the first mounting plate. A drive motor is fixedly mounted on one end of the first mounting plate. The output end of the drive motor is fixedly connected to the drive screw. Two sets of slide rails are fixedly mounted on the top of the base. A movable frame is slidably connected to the slide rails via a slider. A screw sleeve is threaded onto the external part of the drive screw. The top of the screw sleeve is fixedly connected to the movable frame.

[0007] Furthermore, the clamping mechanism includes a second mounting plate, a hinge shaft, a sleeve, and a clamping claw. Multiple sets of hinge shafts are fixedly mounted on the second mounting plate. A sleeve is sleeved around the outside of the hinge shaft, and a clamping claw is fixedly connected to one end of the sleeve.

[0008] Furthermore, the limiting mechanism includes a threaded groove, a first threaded rod, a blocking rod, and a limiting ring. The clamping claw has multiple sets of threaded grooves. The first threaded rod is threadedly connected to the inside of the threaded groove. The blocking rod is fixedly connected to the top of the first threaded rod. The limiting ring is sleeved on the outside of the clamping claw and on one side of the blocking rod.

[0009] Furthermore, the contact extrusion mechanism includes a threaded sleeve, a second threaded rod, a positioning plate, and a knob. The threaded sleeve is fixedly installed on one side of the second mounting plate. The threaded sleeve is internally threaded with the second threaded rod. One end of the second threaded rod is rotatably connected to the positioning plate, and the other end of the second threaded rod is fixedly connected to the knob.

[0010] Furthermore, the top of the movable frame and both sides of the connecting frame are fixedly connected with reinforcing plates.

[0011] Compared with the prior art, the present invention has the following advantages: The clamping mechanism of the present invention can be set at one end of the outer side of the cone sleeve, and the subsequent limiting mechanism can lock the position of the clamping mechanism to prevent the clamping mechanism from moving when the cone sleeve is disassembled. The subsequent contact squeezing mechanism can contact and squeeze one end of the cone sleeve, and the subsequent disassembly driving mechanism can drive the connecting frame, clamping mechanism and limiting mechanism to move. In this way, the cone sleeve can be quickly disassembled and maintained. By using a slow pulling force, the direct hammering removal method is avoided, ensuring the stability of the subsequent measurement of the balance. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-3 This utility model provides a technical solution: a disassembly mechanism for a wind tunnel balance cone sleeve, including a base 1, two sets of support legs 7 fixedly installed at the bottom of the base 1, a disassembly drive mechanism 2 for providing a disassembly power source at the top of the base 1, a connecting frame 3 fixedly installed at the top of the disassembly drive mechanism 2, a clamping mechanism 4 for contacting one end of the cone sleeve fixedly installed at the top of the connecting frame 3, a contact squeezing mechanism 6 for contacting and positioning one end of the cone sleeve on the clamping mechanism 4, and a limiting mechanism 5 for preventing the clamping mechanism 4 from disengaging from one end of the cone sleeve on the outside of the clamping mechanism 4.

[0018] The clamping mechanism 4 can be set at one end of the outer side of the cone sleeve. The limiting mechanism 5 can lock the position of the clamping mechanism 4 to prevent the clamping mechanism 4 from moving when the cone sleeve is disassembled. The contact pressing mechanism 6 can contact and press one end of the cone sleeve. The disassembly drive mechanism 2 can drive the connecting frame 3, the clamping mechanism 4 and the limiting mechanism 5 to move. This makes it easy to quickly disassemble and maintain the cone sleeve. The slow pulling force avoids the direct smashing removal method and ensures the stability of the subsequent measurement of the balance.

[0019] Please see Figures 1-3 The clamping mechanism 4 includes a second mounting plate 15, a hinge shaft 16, a sleeve 17, and a clamping claw 18. Multiple sets of hinge shafts 16 are fixedly mounted on the second mounting plate 15. The sleeve 17 is sleeved on the outside of the hinge shaft 16, and a clamping claw 18 is fixedly connected to one end of the sleeve 17.

[0020] When the conical sleeve needs to be removed, the clamping claw 18 and the sleeve 17 are pulled to rotate around the outside of the hinge shaft 16. This allows the clamping claw 18 to overlap the outside of the conical sleeve, while the sleeve 17 and the clamping claw 18 connected by the hinge shaft 16 can open, making it convenient to position and clamp conical tubes with larger diameters.

[0021] Please see Figures 1-3 The limiting mechanism 5 includes a threaded groove 19, a first threaded rod 20, a blocking rod 21, and a limiting ring 22. The clamping claw 18 has multiple sets of threaded grooves 19. The first threaded rod 20 is threadedly connected to the inside of the threaded groove 19. The blocking rod 21 is fixedly connected to the top of the first threaded rod 20. The limiting ring 22 is sleeved on the outside of the clamping claw 18 and on one side of the blocking rod 21.

[0022] After the gripper 18 is locked in position, the limiting ring 22 is pushed to move, so that the limiting ring 22 contacts the outside of the gripper 18. Then the first threaded rod 20 is threadedly connected to the corresponding threaded groove 19. Then the blocking rod 21 on the first threaded rod 20 can be used to block the limiting ring 22, thereby preventing the gripper 18 from opening and displacing when the cone sleeve is disassembled.

[0023] Please see Figures 1-3 The contact extrusion mechanism 6 includes a threaded sleeve 23, a second threaded rod 24, a positioning plate 25, and a knob 26. The threaded sleeve 23 is fixedly installed on one side of the second mounting plate 15. The second threaded rod 24 is threadedly connected inside the threaded sleeve 23. The positioning plate 25 is rotatably connected to one end of the second threaded rod 24, and the knob 26 is fixedly connected to the other end of the second threaded rod 24.

[0024] Then, the knob 26 is rotated to move the second threaded rod 24 along the inside of the threaded sleeve 23, so that the forward-moving second threaded rod 24 and the positioning plate 25 can be used to contact and position one end of the tapered tube.

[0025] Please see Figures 1-3 The disassembly drive mechanism 2 includes a first mounting plate 8, a drive screw 9, a drive motor 10, a slide rail 11, a slider 12, and a moving frame 13. Two sets of first mounting plates 8 are fixedly installed on the top of the base 1. The drive screw 9 is rotatably connected to the first mounting plate 8. The drive motor 10 is fixedly installed at one end of the first mounting plate 8. The output end of the drive motor 10 is fixedly connected to the drive screw 9. Two sets of slide rails 11 are fixedly installed on the top of the base 1. The moving frame 13 is slidably connected to the slide rails 11 through the slider 12. The external thread of the drive screw 9 is connected to a screw sleeve 14. The top of the screw sleeve 14 is fixedly connected to the moving frame 13.

[0026] When it is necessary to disassemble the tapered tube after it has been fixed, the drive motor 10 drives the drive screw 9 to rotate. In this way, the drive screw 9 and the screw sleeve 14 can be used to pull the moving frame 13 to move through the slide rail 11 and the slider 12, thereby completing the pulling and disassembly of the tapered tube.

[0027] Please see Figures 1-3 The top of the movable frame 13 and both sides of the connecting frame 3 are fixedly connected with reinforcing plates 27. The reinforcing plates 27 can prevent deformation and displacement of the movable frame 13 and the connecting frame 3 when force is applied.

[0028] In use, firstly, the clamping mechanism 4 can be set at one end of the tapered sleeve. Then, the limiting mechanism 5 can lock the position of the clamping mechanism 4 to prevent it from moving during disassembly of the tapered sleeve. Next, the contact pressing mechanism 6 can contact and press one end of the tapered sleeve. Finally, the disassembly drive mechanism 2 can move the connecting frame 3, the clamping mechanism 4, and the limiting mechanism 5. This allows for quick and easy disassembly and maintenance of the tapered sleeve. The slow pulling force avoids direct impact removal, ensuring stable subsequent measurements of the balance. When the tapered sleeve needs to be removed, the clamping jaw 18 and the sleeve 17 are pulled and rotated along the hinge shaft 16. This allows the clamping jaw 18 to engage with the outside of the tapered sleeve, while the sleeve 17 and clamping jaw 18 connected by the hinge shaft 16 can open, facilitating the handling of tapered pipes with larger diameters. After the clamping claw 18 is locked in position, the limiting ring 22 is pushed to move, so that the limiting ring 22 contacts the outside of the clamping claw 18. Then, the first threaded rod 20 is threadedly connected to the corresponding threaded groove 19. Then, the blocking rod 21 on the first threaded rod 20 can contact and block the limiting ring 22, thereby preventing the clamping claw 18 from opening and displacing when disassembling the tapered sleeve. Then, the knob 26 is rotated to move the second threaded rod 24 along the inside of the threaded sleeve 23. In this way, the forward-moving second threaded rod 24 and the positioning plate 25 can contact and position one end of the tapered tube. When it is necessary to disassemble the tapered tube after it has been fixed, the drive motor 10 drives the drive screw 9 to rotate. In this way, the drive screw 9 and the screw sleeve 14 can pull the moving frame 13 to move through the slide rail 11 and the slider 12, thereby completing the pulling and disassembling of the tapered tube.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
