[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0030] Refer to Figure 2 、 Figure 3 and Figure 4, An embodiment provided by the present utility model: A leak detection fixture component for an intake manifold, including a mounting plate 1, the mounting plate 1 provides support, bolt holes are provided around the mounting plate 1, which can facilitate the installation of the mounting plate 1 on the processing operation table. A clamping component is provided at the top of the mounting plate 1. The clamping component includes a clamping plate 2 that provides support and guidance. A guide block 210 that drives the clamping plate 2 to move is fixedly connected to the bottom end of the clamping plate 2. A slide bar 22 that penetrates and is slidably connected to a support rubber pad 21 is provided in the upper part of the clamping plate 2. A disc 24 that cooperates with a first spring 23 to provide elasticity and reset is fixedly connected to the left side of the slide bar 22. A positioning block 213 that limits the moving distance of the slide bar 22 and prevents it from moving out of the clamping plate 2 is fixedly connected to the outer wall of the right side of the slide bar 22. A rubber pad 21 is provided on the right side of the slide bar 22. The rubber pad 21 is made of rubber material, which can increase the tightness of fitting with the intake manifold and increase the stability of clamping the intake manifold. At the same time, the soft rubber material can prevent damage to the intake manifold.
[0031] Further, a U-shaped block 27 is fixedly connected to the top end of the clamping plate 2. The U-shaped block 27 supports a second spring 26. A slider 28 is slidably connected to the lower part of the clamping plate 2 near the U-shaped block 27. A handle is fixedly connected to the top end of the slider 28, which can facilitate the upward movement of the slider 28. The slider 28 provides support and guidance for a convex block 214. A convex block 214 that can cooperate with a second threaded rod 41 to slide into a circular groove 42 to limit the slide bar 22 is fixedly connected to the bottom end of the slider 28. A circular groove 42 that can cooperate with the second threaded rod 41 to limit the slider 28 is provided on the front surface of the slider 28.
[0032] Refer to Figure 1 、 Figure 2 and Figure 4 , An adjusting component is provided on the right side of the slide bar 22. The adjusting component includes a first threaded rod 3, which can be threadedly connected to the slide bar 22. Thus, the position of the rubber pad 21 can be adjusted by rotation to drive the movement, so that it can fit more closely with the irregular surface of the intake manifold. The first threaded rod 3 is threadedly connected to the right side of the slide bar 22, and the rubber pad 21 is fixedly connected to the right side of the first threaded rod 3.
[0033] Refer to Figure 1 、 Figure 2 and Figure 3 , A second threaded rod 41 is threadedly connected to the front surface of the clamping plate 2. An anti-slip sleeve 4 that increases friction to prevent sliding is fixedly connected to the front surface of the second threaded rod 41. The front part of the second threaded rod 41 is threaded, and the rear part is circular. The rear part can be slid into the circular groove 42 to limit the slider 28. The circular shape of the rear part of the second threaded rod 41 is adapted to the circular groove 42.
[0034] Refer to Figure 1 and Figure 2, the guiding block 210 penetrates and is slidably connected to the middle of the clamping plate 2. The bottom end of the mounting plate 1 is fixedly connected with a plurality of supporting blocks 212. The plurality of supporting blocks 212 support the bidirectional threaded rod 211. The left side of the supporting block 212 is rotatably connected with a bidirectional threaded rod 211 that drives the two guiding blocks 210 to move in opposite directions simultaneously by rotation. The left side of the bidirectional threaded rod 211 is fixedly connected with a rocker 25 that drives the bidirectional threaded rod 211 to rotate. The guiding block 210 penetrates and is threadedly connected to the outer wall of the left part of the bidirectional threaded rod 211.
[0035] Refer to Figure 2 , Figure 3 and Figure 4 , the right side of the disc 24 is fixedly connected with a first spring 23. The right end of the first spring 23 is fixedly connected to the left side of the clamping plate 2. By squeezing the irregular surface of the intake manifold through the rubber pad 21, the slide rod 22 moves outward to stretch the first spring 23. Thus, the rubber pad 21 can cooperate with the reverse acting force of the first spring 23 stretched by the slide rod 22, which can adapt to tightly clamp the irregular surface of the intake manifold and improve the clamping stability. A plurality of grooves 29 are formed at the top end of the slide rod 22, and the plurality of grooves 29 are evenly formed on the outer wall top end of the slide rod
[0036] [[ID=?]]Further, the convex block 214 is adapted to the groove 29. After the plurality of rubber pads 21 move to adapt to clamp the irregular intake manifold, at this time, the slide rod 22 can be limited by the convex block 214 sliding into the groove 29. At this time, by rotating the second threaded rod 41 and sliding it into the circular groove 42, the slider 28 is limited. At this time, the rubber pad 21 and the intake manifold can be stably clamped, thus facilitating subsequent leak detection of the intake manifold.
[0037] Further, the left and right sides of the bottom end of the convex block 214 are set as inclined surfaces. Being set as inclined surfaces can be squeezed by the groove 29 and slide upward. When the slider 28 is not limited, the slide rod 22 can move conveniently. After the slider 28 is limited, the slide rod 22 can be limited again by the convex block 214 sliding into the groove 29, which increases the applicability and stability. The top end of the slider 28 is fixedly connected with a second spring 26. The top end of the second spring 26 is fixedly connected to the middle bottom end of the U-shaped block 27. By the slider 28 moving upward to squeeze the second spring 26, the slider 28 can be reset by the reverse acting force of the second spring 26 being squeezed.
[0038] Refer to Figure 1 , Figure 2 and Figure 3 It should be noted that there seems to be an error in the numbering in the original text. The "[[ID=?]]" is added for the purpose of indicating that there may be an incorrect numbering in the original., the rear part of the second threaded rod 41 is set to be circular. Being set to be circular allows it to slide into the circular groove 42 to limit the slider 28. The rear end of the second threaded rod 41 slides on the inner wall of the circular groove 42. There are multiple groups of slide rods 22. The multiple groups of slide rods 22 uniformly penetrate and are arranged on the upper part of the clamping plate 2. The multiple groups of slide rods 22, in cooperation with the rubber pads 21 and the first springs 23, can stably clamp the irregular intake manifold adaptively. There are two groups of clamping plates 2 and guide blocks 210. The two groups of clamping plates 2 and guide blocks 210 are symmetrically arranged with the center line of the mounting plate 1 as the axis of symmetry. The two groups of clamping plates 2 support the multiple groups of slide rods 22 and rubber pads 21. Through the two groups of clamping plates 2 and the multiple groups of rubber pads 21, the intake manifold can be stably clamped in the middle position, thus facilitating subsequent leak detection operations on the intake manifold and improving the detection efficiency and quality.
[0039] Working principle: When in use, by rotating the rocker 25, the bidirectional threaded rod 211 is driven to rotate. The rotation of the bidirectional threaded rod 211 drives the two guide blocks 210 to move in opposite directions simultaneously. The guide blocks 210 drive the fixedly connected clamping plates 2 to move synchronously. The two clamping plates 2 approach or move away from each other, thereby adjusting the distance between the two clamping plates 2 to adapt to intake manifolds of different sizes.
[0040] When the irregular surface of the intake manifold contacts the rubber pad 21, the irregular surface will exert extrusion on the rubber pad 21. After the rubber pad 21 is extruded, it will push the fixedly connected slide rod 22 to move outward. The outward movement of the slide rod 22 will stretch the first spring 23. The reverse elastic force generated by the first spring 23 and the extrusion force of the irregular surface form a dynamic balance, enabling the rubber pad 21 to closely fit the irregular surface of the intake manifold and realizing the tight clamping of the irregular intake manifold.
[0041] According to the irregular degree of the intake manifold, the initial position of the rubber pad 21 can be adjusted by rotating the first threaded rod 3. Since the first threaded rod 3 is threadedly connected to the slide rod 22, rotating the first threaded rod 3 can make the rubber pad 21 move along the axial direction of the slide rod 22, so that the rubber pad 21 can fit more closely with the irregular surface of the intake manifold, further improving the clamping stability.
[0042] After multiple groups of rubber pads 21 move to positions adapted to the irregular intake manifold and pre-clamp the intake manifold, when the sliding rod 22 moves, it will drive the groove 29 to squeeze the slider 28, causing the slider 28 to move upward along the clamping plate 2, while compressing the second spring 26. The movement of the slider 28 drives the convex block 214 to move upward. When the convex block 214 moves to a position aligned with the groove 29 at the top of the sliding rod 22, the slider 28 is released. Under the reverse acting force of the second spring 26, the slider 28 moves downward. The inclined surface design of the convex block 214 enables it to smoothly slide into the groove 29. When the intake manifold is stably clamped by the rubber pad 21 adaptively, at this time, the second threaded rod 41, which is threadedly connected to the clamping plate 2, moves inward. Since the rear part of the second threaded rod 41 is adapted to the circular groove 42 on the slider 28, the rear part of the second threaded rod 41 will slide into the circular groove 42 to limit the slider 28. The slider 28 limits the convex block 214, the groove 29, and the sliding rod 22. At this time, the rubber pad 21 and the intake manifold can be stably fixed to maintain the stability of the clamping state, facilitating subsequent leak detection operations on the intake manifold. After stably clamping the intake manifold, leak detection-related operations can be performed on the intake manifold, improving the subsequent detection efficiency and detection quality.
[0043] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
