Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipe clamping, specifically an adaptive clamping and locking mechanism for tubular structural components. Background Technology
[0002] Tubular structures are hollow columnar structures in mechanics, characterized by closed or semi-closed internal cavities. Their structural properties can effectively prevent the penetration of corrosive media. Due to special requirements such as weight reduction and functional requirements, they can exhibit five failure modes under axial compressive loads, including progressive buckling and overall instability. Progressive buckling is often used in the core layer of sandwich structures. Expansion tubes, splitting tubes, and overturning tubes are suitable for the design of anti-collision components. Metal tubular structures are prone to overall instability under dynamic loads, while composite tubular structures exhibit higher energy absorption capacity. Failure modes involve mechanisms such as delamination bending and transverse shearing.
[0003] However, current centering clamps use flexible rollers at the end of the guide rod to contact the pipe wall when clamping tubular components. Therefore, if cutting or drilling forces are applied to the pipe, it is easy for it to deviate. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an adaptive clamping and locking mechanism for tubular structural components, which solves the problems mentioned in the background.
[0005] This utility model provides the following technical solution: an adaptive clamping and locking mechanism for tubular structural components, including a support base, a locking mechanism at one upper end of the support base, a centering pad on one side of the locking mechanism above the support base, the locking mechanism including: a limiting frame and a bottom support plate, an adjusting bolt installed inside the limiting frame, a clamping pad installed at the lower end of the adjusting bolt, and sliding grooves at both ends of the inner sidewall of the limiting frame corresponding to the sliding grooves of the bottom support plate, with locking bolts installed inside the sliding grooves at both ends of the bottom support plate.
[0006] As a further embodiment of this utility model: a movable washer is provided on one side of the centering pad, and an arc-shaped swing groove is formed in the inner annular array of the movable washer. A guide ring is provided inside the arc-shaped swing groove, and a centering guide rod is provided inside the guide ring.
[0007] As a further embodiment of this utility model: one end of the centering guide rod is mounted with a rotating shaft above the centering pad, and a swing rod is installed between the guide collar and the movable washer.
[0008] As a further improvement of this utility model: a guide rail is installed on the upper surface of the support base, and a limit slider is installed on the lower surface of the locking mechanism outside the guide rail.
[0009] As a further embodiment of this utility model: the adjusting bolt is engaged and rotatably connected to the limiting frame, and the clamping pad is movably connected to the adjusting bolt.
[0010] As a further improvement of this utility model: the locking bolt is rotatably connected to the bottom support plate, and the length of the bottom support plate is greater than the length of the clamping pad.
[0011] As a further embodiment of this utility model: the centering guide rod is slidably connected to the guide sleeve, a rack is installed on the outer side wall of the movable washer, and a drive gear is installed on one side of the rack on the side surface of the centering pad.
[0012] As a further embodiment of this utility model: the catheter collar is rotatably connected to the movable washer via the swing rod, and the centering guide rod is rotatably connected to the centering pad via the rotating shaft.
[0013] Compared with the prior art, the beneficial effects of this utility model are: After locking the bottom support plate by rotating the locking bolts, torque is applied to the adjusting bolts inside the remaining three sides of the limiting frame. The three clamping pads are adjusted to clamp the pipe to the left, right and top respectively, thus ensuring that the pipe is locked and preventing the pipe from shifting during processing.
[0014] The movable washer rotates outside the centering pad, and the guide ring inside the rotating movable washer is driven to move. This allows the centering guide rod, located away from the rotating shaft, to move synchronously towards the center of the movable washer, thus centering the pipe and facilitating subsequent clamping.

[0017] 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.
[0018] like Figure 1-5 As shown, this embodiment provides an adaptive clamping and locking mechanism for a tubular structural component, including a support base 1. A locking mechanism 2 is provided at one upper end of the support base 1, and a centering pad 3 is provided on one side of the locking mechanism 2 above the support base 1. The locking mechanism 2 includes a limiting frame 201 and a bottom support plate 204. An adjusting bolt 202 is installed inside the limiting frame 201, and the adjusting bolt 202 is rotatably connected to the limiting frame 201. A clamping pad 203 is installed at the lower end of the adjusting bolt 202. The holding plate 203 is movably connected to the adjusting bolt 202. The inner sidewall of the limiting frame 201 is provided with a sliding groove 205 at both ends of the bottom support plate 204. Locking bolts 206 are provided at both ends of the bottom support plate 204 corresponding to the sliding grooves 205. The locking bolts 206 are rotatably connected to the bottom support plate 204. The length of the bottom support plate 204 is greater than the length of the holding plate 203. The upper surface of the support base 1 is equipped with a guide rail 4. The lower surface of the locking mechanism 2 is equipped with a limiting slider on the outside of the guide rail 4.
[0019] like Figure 2-3As shown, in this embodiment, a movable washer 301 is provided on one side of the centering pad 3. A limiting rotation groove is installed on the side surface of the centering pad 3 corresponding to the side surface of the movable washer 301. An arc-shaped swing groove 302 is formed in an annular array inside the movable washer 301. A guide ring 304 is provided inside the arc-shaped swing groove 302. A centering guide rod 303 is provided inside the guide ring 304. The centering guide rod 303 is slidably connected to the guide ring 304. The movable washer 301... A rack is installed on the outer side wall of the centering plate 3. A drive gear is installed on one side of the rack on the side surface of the centering plate 3. A crank is connected to the other end of the drive gear. A rotating shaft 306 is installed on one end of the centering guide rod 303 above the centering plate 3. A swing rod 305 is installed between the guide sleeve 304 and the moving washer 301. The guide sleeve 304 is rotatably connected to the moving washer 301 through the swing rod 305. The centering guide rod 303 is rotatably connected to the centering plate 3 through the rotating shaft 306.
[0020] The working principle of this utility model is as follows: During use, first determine the overall length of the pipe. Adjust the locking mechanism 2 along the guide rail 4 to the distance between it and the centering pad 3. Then, insert the pipe, clamped by the guide rail, into the locking mechanism 2. Insert the other end of the pipe into the moving washer 301. Next, control the rotation of the drive gear using the crank handle. The drive gear meshes with the rack on the outside of the moving washer 301, thus controlling the rotation of the moving washer 301 on the outside of the centering pad 3. The rotating moving washer 301 causes the guide tube collar 304 inside to move. Simultaneously, the moving guide tube collar 304 is moved by the centering guide rod 30. Under the limiting action of 3, the centering guide rod 303 is moved synchronously towards the center of the moving washer 301 at the end away from the rotating shaft 306. After centering the pipe, the clamping pad 203 is moved upward inside the slide groove 205 to the position of contacting the lower surface of the pipe. Then, the bottom support plate 204 is locked by rotating the locking bolt 206. Then, the torque is applied to the adjusting bolts 202 inside the remaining three surfaces of the limiting frame 201 to adjust the three clamping pads 203 to clamp the pipe to the left, right and top respectively. This ensures that the pipe is locked and avoids pipe deviation during processing.
