This structure can fix multiple gas cylinders of different specifications at the same time, realizing one-time detection, and greatly improving the detection efficiency;

[0015] The clamping surface of the clamping plate is provided with anti-slip lines, which increases the friction with the gas cylinder, further ensures the stable clamping of the gas cylinder, and prevents the gas cylinder from sliding or shifting during the detection process;

[0016] The lifting assembly can be telescoped by an electric push rod to drive the sliding frame to slide in the second guiding groove on the support, thereby adjusting the height of the clamping frame to meet different height requirements and facilitating the adjustment of the overall clamping height according to the needs of the detection operation;

[0017] The positioning assembly can adjust the horizontal position of the clamping seat on the clamping frame through a positioning pin, a second spring, etc., can change the clamping distance between each gas cylinder, meet the spacing requirements under different working conditions, and improve the flexibility and applicability of the tooling.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figure 1-2, the present invention provides a technical solution: a clamping tooling for gas cylinder detection, including a frame 1. On both sides of the upper wall of the frame 1, a pair of brackets 2 are fixedly provided. On the opposite side walls of the pair of brackets 2, a pair of slidable carriages 3 are provided. Between the pair of carriages 3, a pair of clamping frames 4 are slidably arranged. On both sides of the clamping frame 4, first guide blocks 5 are provided. On the carriage 3, first guide grooves 6 matching the first guide blocks 5 are provided. In one of the first guide grooves 6, a tension screw 7 is provided. At one end of the carriage 3, a motor 8 connected to one end of the tension screw 7 is provided. On the clamping frame 4, a number of horizontally slidable clamping seats 9 are provided. Inside the clamping seat 9, an adjusting plate 10 is slidably installed. On the side wall of the adjusting plate 10, a horizontal groove 11 is provided. In the horizontal groove 11, a pair of sliding blocks 12 are slidably arranged. On the side walls of the pair of sliding blocks 12, a pair of clamping plates 13 are hinged. One ends of the pair of clamping plates 13 are respectively hinged to the inner walls on both sides of the clamping seat 9. On the side wall of the adjusting plate 10 facing away from the clamping plate 13, an adjusting rod 14 is fixedly installed. On the clamping seat 9, a through hole for the adjusting rod 14 to pass through is provided. Along the length direction of the clamping frame 4, a strip-shaped groove 15 for the adjusting rod 14 to pass through is provided. The adjusting rod 14 can horizontally slide in the strip-shaped groove 15. Between the adjusting plate 10 and the inner wall of the clamping frame 4, a first spring 16 sleeved on the outer side of the adjusting rod 14 is provided. On the clamping frame 4, a limiting component connected to the adjusting rod 14 is provided. Between the clamping seat 9 and the clamping frame 4, a positioning component is provided. Between the carriage 3 and the bracket 2, a lifting component is provided.

[0025] By adopting the above technical solution, the frame 1 provides support for the entire clamping tooling. The carriage 3 on the bracket 2 can slide up and down, providing a vertical movement space for the clamping operation. Driven by the motor 8, the tension screw 7 drives the first guide block 5 on the carriage 3 to move, making the pair of clamping frames 4 approach or move away from each other. The clamping seat 9 inside the clamping frame 4 can slide horizontally. The clamping plate 13 inside it realizes self-adaptive angle adjustment through the adjusting plate 10, the adjusting rod 14 and the first spring 16 to clamp gas cylinders of different specifications. The above components realize the simultaneous clamping of gas cylinders of different specifications, improve the detection efficiency, and reduce the trouble of multiple adjustments and fixture replacements due to different gas cylinder specifications.

[0026] In this embodiment, it is further set that the limiting component includes a number of tooth grooves 17 continuously arranged on the upper wall of the adjusting rod 14 along the length direction of the adjusting rod 14. On the outer wall of the clamping frame 4, a vertical groove 18 is provided. In the vertical groove 18, a movable block 19 that can slide up and down is provided. On the side wall of the movable block 19, a connecting plate 20 is provided. On the lower wall of the connecting plate 20, a tooth key 21 that can be inserted into the tooth groove 17 is provided. Above the connecting plate 20, a support 22 connected to the outer wall of the clamping frame 4 is provided. On the support 22, a wing bolt 23 is rotatably connected. The lower end of the wing bolt 23 is movably connected to the upper wall of the connecting plate 20.

[0027] By adopting the above technical solution, the tooth grooves 17 on the adjusting rod 14 cooperate with the tooth keys 21 on the moving block 19. The connecting plate 20 is pushed by the butterfly bolt 23, so that the tooth key 21 is inserted into or disengaged from the tooth groove 17. When the tooth key 21 is inserted into the tooth groove 17, the position of the adjusting rod 14 can be locked to prevent the adjusting plate 10 and the clamping plate 13 from moving; when the tooth key 21 disengages from the tooth groove 17, the adjusting rod 14 can move freely, realizing the adjustment of the clamping plate 13, ensuring the stability of the position of the clamping plate 13 during the detection process, preventing the loosening of the clamping plate 13 from affecting the clamping effect on the gas cylinder, and improving the safety and reliability of the detection.

[0028] In this embodiment, it is further set that the positioning component includes a plurality of positioning holes 24 arranged along the length direction of the clamping frame 4 and provided on the upper wall of the clamping frame 4. A positioning frame 25 is provided on the upper wall of the clamping seat 9. A positioning pin 26 that can move up and down is slidably inserted on the upper wall of the positioning frame 25. The lower end of the positioning pin 26 is inserted into the positioning hole 24, and a top plate 27 is fixedly provided at the upper end. A second spring 28 is installed between the top plate 27 and the positioning frame 25.

[0029] By adopting the above technical solution, when the top plate 27 is lifted, the positioning pin 26 slides upward in the positioning frame 25, stretching the second spring 28, so that the positioning pin 26 is withdrawn from the positioning hole 24. At this time, the clamping seat 9 can be moved; when the top plate 27 is released, under the elastic force of the second spring 28, the positioning pin 26 is inserted into the positioning hole 24 again, fixing the clamping seat 9 at a new position, thus facilitating the adjustment of the horizontal position of the clamping seat 9, meeting the requirements for different spacing, improving the flexibility of the tooling, and being able to flexibly adjust the relative position of the gas cylinder according to different working conditions.

[0030] In this embodiment, it is further set that the lifting component includes second guide grooves 29 provided on the side walls of a pair of the brackets 2. A pair of second guide blocks 30 that are slidably connected to the second guide grooves 29 are provided on the side walls of a pair of the sliding frames 3. An electric push rod 31 is provided on the side wall of one of the brackets 2, and the telescopic end of the electric push rod 31 is fixedly connected to the lower wall of one of the guide blocks.

[0031] By adopting the above technical solution, when the electric push rod 31 expands and contracts, it drives one of the guide blocks to slide in the second guide groove 29 of the bracket 2. Since the guide block is connected to the sliding frame 3, the sliding frame 3 moves vertically on the bracket 2, realizing the height adjustment of the clamping frame 4, meeting the detection requirements for different heights, improving the adaptability of the tooling to different detection scenarios, and facilitating the operator to adjust the operation height of the tooling according to the actual situation.

[0032] In this embodiment, it is further set that a pair of third guide grooves 32 are provided on the inner walls of both sides of the clamping seat 9, and a pair of third guide blocks 33 that are slidably connected to the third guide grooves 32 are provided at both ends of the adjusting plate 10.

[0033] By adopting the above technical solution, the stability of the adjusting plate 10 during movement and adjustment is ensured, the accuracy and reliability of the adjustment of the clamping plate 13 are improved, and guarantee is provided for the stable clamping of the gas cylinder.

[0034] In this embodiment, it is further set that a pair of guide rails 34 are provided on the side wall of the clamping frame 4 close to the clamping seat 9, and a pair of sliders 35 slidably connected to the guide rails 34 are provided on the outer wall of the clamping seat 9.

[0035] By adopting the above technical solution, the slider 35 on the outer wall of the clamping seat 9 slides on the guide rail 34 of the clamping frame 4, providing guidance for the horizontal sliding of the clamping seat 9, ensuring its smoothness and accuracy during movement, and preventing jamming or deviation.

[0036] In this embodiment, it is further set that anti-slip lines are provided on the clamping surface of the clamping plate 13.

[0037] By adopting the above technical solution, anti-slip lines are provided on the clamping surface of the clamping plate 13, increasing the friction between the clamping plate 13 and the gas cylinder, enabling the clamping plate 13 to better grip the surface of the gas cylinder when clamping the gas cylinder, preventing the gas cylinder from sliding due to vibration or other external forces during the detection process, and ensuring the safety and stability of the detection process.

[0038] In this embodiment, it is further set that the number of the clamping seats 9 is at least four.

[0039] By adopting the above technical solution, setting at least four clamping seats 9 can accommodate multiple gas cylinders of different specifications at the same time, expanding the clamping capacity and detection range of the tooling, improving the working efficiency of the tooling, enabling the detection of multiple gas cylinders of different specifications at the same time, reducing the number of times and time costs of batch detection, and improving the overall efficiency of gas cylinder detection.

[0040] Those skilled in the art should connect the components in this case in sequence. For the specific connection and operation sequence, reference should be made to the following working principle. The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process.

[0041] Embodiment: First, according to the detection requirements, start the electric push rod 31 and adjust the height of the clamping frame 4 through the lifting component. The telescopic end of the electric push rod 31 drives the guide block to slide in the second guide groove 29, thereby changing the height position of the clamping frame 4. If it is necessary to adjust the distance between the gas cylinders, lift the top plate 27 in the positioning component to pull out the positioning pin 26 from the positioning hole 24, and then slide the clamping seat 9 along the length direction of the clamping frame 4. After adjusting it to the appropriate position, release the top plate 27. Under the elastic force of the second spring 28, the positioning pin 26 is inserted into the positioning hole 24 again to achieve the adjustment of the horizontal position of the clamping seat 9. Then, place gas cylinders of different specifications to be detected at the corresponding positions to ensure that the gas cylinders are in a state where they can be clamped. Start the motor 8 to drive the opposing lead screw 7 to rotate. The opposing lead screw 7 drives the first guide block 5 on the carriage 3 to move in the first guide groove 6, causing a pair of clamping frames 4 to approach each other. As the clamping seat 9 moves towards the gas cylinder, a pair of clamping plates 13 rotate at the hinge, the included angle becomes smaller, and at the same time, the adjusting plate 10 and the adjusting rod 14 are pushed outward to compress the first spring 16. Continue to move until the clamping plates 13 in each clamping seat 9 are in full contact with and clamp gas cylinders of different specifications. Gas cylinders of different specifications will cause different included angles of each clamping plate 13, achieving the simultaneous clamping of multiple gas cylinders of different specifications. Then, rotate the wing bolt 23 to push the connecting plate 20 to drive the tooth key 21 to slide downward, so that the tooth key 21 is inserted into the tooth groove 17 on the adjusting rod 14, thereby fixing the adjusting rod 14 to ensure the locking of the position of the clamping plate 13. At this time, the fixing of the gas cylinder is completed, and the detection operation can be carried out on multiple gas cylinders of different specifications simultaneously. After the detection is completed, first release the locking of the clamping plate 13, operate the limit component to make the tooth key 21 disengage from the tooth groove 17, and then reverse the motor 8 to rotate the opposing lead screw 7 to make the clamping frame 4 and the clamping plate 13 release the clamping of the gas cylinder, and then the detected gas cylinder can be taken out, which is convenient to use.

[0042] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation. An element defined by the statement "including one..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.

[0043] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
