[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0028] Please see Figure 1-3 As shown, this utility model is a tooling fixture for a test chamber trolley, comprising:
[0029] Car body 11;
[0030] The clamping component includes a support bar 21, a limiting ring 23, an internal threaded ring 24, a threaded rod 25, a handle 26, and a clamping ring 27. The support bar 21 is welded to both ends of the top of the vehicle body 11. Several limiting rings 23 are located on the upper part of the support bar 21. The internal threaded ring 24 is located at the middle of the top of the limiting ring 23. The threaded rod 25 is threadedly connected to the middle of the internal threaded ring 24. The handle 26 is fixedly connected to the top of the threaded rod 25. The clamping ring 27 is located at the bottom of the threaded rod 25.
[0031] Rotating the handle 26 drives the threaded rod 25 to rotate, causing the clamping ring 27 to move downward and tightly clamp onto the top of the projectile, forming a double-limited fixing structure. This greatly improves the adaptability of the tooling fixture to projectiles of various specifications and reduces the cost and time loss of replacing tooling fixtures due to changes in projectile specifications.
[0032] A rubber ring 28 is glued to the bottom of the clamp 27.
[0033] The top of the support bar 21 is provided with an inner groove 22, and the inner groove 22 is evenly distributed.
[0034] Projectiles of different specifications, regardless of diameter or shape, can be placed inside the inner groove 22, breaking through the limitation of traditional tooling fixtures that can only be adapted to specific projectiles.
[0035] The bottom of the limiting ring 23 is fixed with a support frame 33, the inside of the support frame 33 is provided with an insertion hole 34, and the top of the support bar 21 is provided with an insertion rod 31, which is inserted and connected to the inside of the insertion hole 34.
[0036] Insert rod 31 into the interior of insertion hole 34, so that support frame 33 and limiting ring 23 are installed on top of support bar 21, which facilitates the fixation of projectile body later.
[0037] The outer surface of the insertion rod 31 is threaded with a nut ring 32, which is fastened to the top of the support frame 33;
[0038] The nut ring 32 is fixed to the outside of the insertion rod 31 to prevent loosening between the insertion rod 31 and the insertion hole 34.
[0039] Working principle: During the installation of the tooling fixture, the support frame 33 is pre-fixed to the bottom of the limiting ring 23, forming a stable basic support structure. The insertion rod 31 is aligned with the insertion hole 34 on the upper part of the support bar 21 and inserted. Then, the nut ring 32 is put on the outside of the insertion rod 31 and rotated. Through the threaded engagement between the nut ring 32 and the insertion rod 31, the nut ring 32 is tightened along the insertion rod 31. During the tightening process, the nut ring 32 exerts downward pressure on the limiting ring 23. Combined with the positioning effect of the insertion rod 31 and the insertion hole 34, the limiting ring 23 is firmly installed on the upper part of the support bar 21, completing the initial installation and positioning of the tooling fixture.
[0040] When the projectile needs to be fixed for testing, the projectile is placed stably inside the inner groove 22. The shape and size design of the inner groove 22 can provide initial positioning and support for the projectile, restricting its horizontal movement. After the projectile is placed, the handle 26 is turned. The handle 26 is connected to the threaded rod 25, which drives the threaded rod 25 to rotate. Since the threaded rod 25 is connected to the clamping ring 27 through threaded transmission, the rotational motion of the threaded rod 25 is converted into the vertical downward linear motion of the clamping ring 27. As the threaded rod 25 continues to rotate, the clamping ring 27 gradually approaches the top of the projectile and finally clamps it tightly. The clamping ring 27 cooperates with the inner groove 22 to fix the projectile from both the top and bottom, forming a stable clamping structure. No matter how the projectile specifications change, the height of the limiting ring 23 can be adjusted by adjusting the nut ring 32, and the position of the clamping ring 27 can be adjusted by turning the handle 26. This allows for the rapid and stable clamping and fixing of projectiles of different specifications, meeting diverse testing needs. After the test is completed, turn the handle 26 in the opposite direction to raise the clamp 27 and release the projectile. The projectile can then be removed from the inner groove 22, completing the entire test operation process.
[0041] Please see Figure 1 , Figure 4 As shown, this embodiment, based on the above embodiment, further includes:
[0042] The anti-fall-off component includes a pressure plate 41, a support rod 43, a spring 44, and a limiting plate 45. The support rod 43 is welded to one side of the outer surface of the vehicle body 11, the spring 44 is wrapped around the outside of the support rod 43, the limiting plate 45 is fixed to the outside of the support rod 43, and the pressure plate 41 is movably connected through the outer surface of the support rod 43.
[0043] The spring 44 generates elastic force, which can stretch the pressure plate 41, causing the pressure plate 41 to press against the outside of the projectile. This can restrict the position of the projectile after clamping, preventing the projectile from falling off during transportation.
[0044] A base plate 42 is fixed to the bottom of the vehicle body 11. A guide groove 47 is provided on the top of the base plate 42. A guide block 46 is provided on the bottom of the pressure plate 41. The guide block 46 is movably connected to the inside of the guide groove 47.
[0045] When the pressure plate 41 is stretched, the guide block 46 slides inside the guide groove 47 at the same time, which guides the pressure plate 41 during stretching.
[0046] Working principle: After the projectile is initially clamped and fixed by the clamping ring 27, the limiting structure composed of the spring 44 and the pressure plate 41 begins to function. One end of the spring 44 is connected to the fixed bracket of the tooling fixture, and the other end is fixedly connected to the pressure plate 41. In its natural state, the spring 44 is in a pre-tightened state of tension or compression, storing elastic potential energy. When further limiting of the projectile is required, the outer side of the projectile pushes the pressure plate 41, causing the pressure plate 41 to move closer to the projectile. During this process, the spring 44 is further stretched or compressed, increasing its elastic potential energy. The spring 44 generates a spring force opposite to the direction of movement of the pressure plate 41. This spring force is evenly applied to the outer side of the projectile through the pressure plate 41, forming a surrounding pressure. Together with the clamping forces of the clamping ring 27 and the inner groove 22, it constitutes a stable three-dimensional constraint system, effectively limiting the horizontal displacement of the projectile and ensuring that the projectile will not fall off due to shaking or bumping during transportation.
[0047] During the movement of the pressure plate 41, the guiding mechanism composed of the guide block 46 and the guide groove 47 plays a key role. The guide block 46 is fixedly installed on the pressure plate 41, and the guide groove 47 is opened on the support structure of the tooling fixture. The extension direction of the guide groove 47 is consistent with the movement direction of the pressure plate 41. When the pressure plate 41 is stretched and moved under the combined action of the spring force 44 and the reaction force of the projectile, the guide block 46 slides along the inner wall of the guide groove 47. The guide groove 47 provides precise guidance for the movement of the pressure plate 41 by limiting the guide block 46, ensuring that the pressure plate 41 always moves smoothly in the predetermined direction, avoiding tilting, jamming or deviation of the pressure plate 41 during the movement, ensuring that the spring force 44 can be accurately and evenly transmitted to the outside of the projectile, and improving the stability and reliability of the entire limiting structure.
