Description

Technical Field

[0001] This utility model relates to the field of gas cylinder processing technology, specifically to an assembly fixture for composite gas cylinders. Background Technology

[0002] In existing composite gas cylinder assembly technologies, traditional tooling and equipment have many limitations. On the one hand, some assembly tooling has a low degree of automation, and processes such as assembling the gas cylinder liner and valve, and fiber winding and positioning still rely on manual operation. Manual operation is not only inefficient and difficult to meet the needs of large-scale production, but also the assembly quality is greatly affected by the operator's experience and skill level, which can easily lead to assembly errors, resulting in problems such as poor gas cylinder sealing and unstable pressure bearing capacity, posing safety hazards.

[0003] Traditional assembly fixtures in the existing technology cannot accurately position the gas cylinder according to its size or length during use, causing the gas cylinder to shake during subsequent processing, which affects the processing effect and needs to be improved. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides an assembly fixture for composite gas cylinders, which solves the technical problem that the existing technology cannot accurately position the gas cylinder according to its size or length.

[0005] According to one aspect, at least one embodiment of the present invention provides an assembly fixture for a composite gas cylinder, comprising: a base, a connecting frame fixedly connected to the top of the base, a limiting rod fixedly connected to the top of the base, a fixing plate slidably connected to the circumferential surface of the limiting rod, a connecting rod fixedly connected to the bottom of the fixing plate, a lower pressure plate fixedly connected to the end of the connecting rod away from the fixing plate, an effective clamping mechanism provided on the top of the base, the effective clamping mechanism including a drive motor, the drive motor passing through the top of the connecting frame, a first threaded rod fixedly connected to the end of the output shaft of the drive motor, a threaded sleeve threadedly connected to the circumferential surface of the first threaded rod, a hollow plate fixedly connected to the top of the base, a hollow block fixedly connected to the bottom of the inner wall of the hollow plate, and a support block slidably connected to the inner wall of the hollow block.

[0006] For example, in the assembly fixture of a composite gas cylinder provided in at least one embodiment of the present invention, a return spring is fixedly connected to the bottom of the support block, and the end of the return spring away from the support block is fixedly connected to the bottom of the inner wall of the hollow block. The design of the return spring is beneficial to effectively clamp the gas cylinder according to its size.

[0007] The side section of the threaded sleeve is rectangular. The side of the connecting bracket away from the limiting rod is fixedly connected to the side section of the threaded sleeve. Fixing the connecting bracket to the side section of the threaded sleeve makes it easier to fix without manual pressing by staff.

[0008] The hollow plate has a concave side section, the reset spring is initially set to a relaxed state, and the hollow plate has a rectangular side section, which helps to effectively protect the gas cylinder and prevent it from rolling off.

[0009] The number of hollow blocks is set to several, and they are arranged in a linear array at the bottom of the inner wall of the hollow plate. The support blocks are made of rubber, which helps to avoid scratching the surface of the gas cylinder.

[0010] According to another aspect, at least one embodiment of this utility model also provides an assembly fixture for a composite gas cylinder, comprising: an adjustable clamping mechanism provided on the side of the hollow plate, the adjustable clamping mechanism including a hollow strip, the hollow strip being fixedly connected to the side of the hollow plate, a connecting motor passing through the side of the hollow strip, a bidirectional screw being fixedly connected to the end of the output shaft of the connecting motor, a threaded block being threadedly connected to the circumferential surface of the bidirectional screw, a rectangular plate being fixedly connected to the top of the threaded block, and a suction cup being fixedly connected to the side of the rectangular plate. The above design is beneficial for effective clamping according to the length of the gas cylinder.

[0011] For example, in the assembly tooling of a composite gas cylinder provided in at least one embodiment of the present invention, a gas nozzle is fixedly connected to the outer surface of the suction cup, and a sliding plug is inserted into the inner wall of the gas nozzle. The design of the sliding groove is conducive to quickly inflating the inside of the suction cup.

[0012] The side section of the hollow strip is concave, and the number of threaded blocks is set to four. The design of the hollow strip helps to ensure the stable operation of the connected motor.

[0013] The number of rectangular plates is set to four, and the number of suction cups is set to four. The four suction cups are advantageous for clamping both ends of the gas cylinder.

[0014] The side cross-section of the lower pressure plate is set to semi-circular, and the number of lower pressure plates is set to two. Setting the number of lower pressure plates to two is beneficial for clamping two gas cylinders at one time.

[0015] The beneficial effects of the embodiments of this utility model are as follows:

[0016] 1. In this utility model, the driving force of the transmission motor drives the first threaded rod, threaded sleeve, hollow plate, hollow block, return spring, support block and other components to cooperate with each other, realize the start of the motor driving the motor through the top of the connecting frame, thereby driving the first threaded rod fixed at the end of the output shaft to rotate. The rotation of the first threaded rod drives the threaded sleeve threaded to the circumferential surface to move. During the clamping process of the gas cylinder, it can effectively clamp according to the size of the gas cylinder.

[0017] 2. In this utility model, the driving force of the connecting motor drives the hollow bar, bidirectional screw, threaded block, rectangular plate, suction cup, air nozzle and other components to work together to start the connecting motor that runs through the side of the hollow bar. At the same time, it drives the bidirectional screw fixed at the end of the output shaft to rotate. The rotation of the bidirectional screw drives the two sets of threaded blocks that are threaded to the circumferential surface to move relative to each other. When the two sets of threaded blocks move closer to each other, they drive the rectangular plate fixed at the top to move closer to each other. During the clamping process of the gas cylinder, it can be clamped according to the length of the gas cylinder to avoid shaking. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0026] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] like Figures 1-5The diagram illustrates an assembly fixture for a composite gas cylinder according to an embodiment of the present invention, comprising: a base 1, a connecting frame 2 fixedly connected to the top of the base 1, a limiting rod 3 fixedly connected to the top of the base 1, a fixing plate 4 slidably connected to the circumferential surface of the limiting rod 3, a connecting rod 5 fixedly connected to the bottom of the fixing plate 4, a lower pressure plate 6 fixedly connected to the end of the connecting rod 5 away from the fixing plate 4, an effective clamping mechanism 7 provided on the top of the base 1, the effective clamping mechanism 7 including a drive motor 71, the drive motor 71 passing through the top of the connecting frame 2, a first threaded rod 72 fixedly connected to the end of the output shaft of the drive motor 71, a threaded sleeve 73 threadedly connected to the circumferential surface of the first threaded rod 72, a hollow plate 74 fixedly connected to the top of the base 1, a hollow block 75 fixedly connected to the bottom of the inner wall of the hollow plate 74, and a support block 77 slidably connected to the inner wall of the hollow block 75.

[0032] In some examples, a return spring 76 is fixedly connected to the bottom of the support block 77, and the end of the return spring 76 away from the support block 77 is fixedly connected to the bottom of the inner wall of the hollow block 75. The design of the return spring 76 is conducive to effective clamping according to the size of the gas cylinder.

[0033] The side section of the threaded sleeve 73 is set as rectangular. The side of the connecting bracket 2 away from the limiting rod 3 is fixedly connected to the side section of the threaded sleeve 73. The connection bracket 2 is fixed to the side section of the threaded sleeve 73, which is beneficial to eliminate the need for manual pressing and fixing by the staff.

[0034] The side section of the hollow plate 74 is set to concave, the initial state of the return spring 76 is set to relaxed, and the side section of the hollow plate 74 is set to rectangular, which is beneficial to effectively protect the gas cylinder and prevent it from rolling off.

[0035] The number of hollow blocks 75 is set to several, and they are arranged in a linear array at the bottom of the inner wall of the hollow plate 74. The support block 77 is made of rubber, which helps to avoid scratching the surface of the gas cylinder.

[0036] For example, such as Figures 1-5As shown, when it is necessary to clamp the gas cylinder, the operator places the gas cylinder on top of the support block 77. When the gas cylinder is placed on top of the support block 77, the support block 77 slides downward on the hollow block 75 under the weight of the gas cylinder, thereby compressing the return spring 76 into a taut state. Then, the operator starts the motor drive motor 71 that passes through the top of the connecting frame 2, thereby driving the first threaded rod 72 fixed at the end of the output shaft to rotate. The rotation of the first threaded rod 72 drives the threaded sleeve 73 threadedly connected to the circumferential surface to move, and at the same time causes the connecting frame 2 fixed to the side of the threaded sleeve 73 to move within the limit. The circumferential surface of the positioning rod 3 slides downward. When the connecting frame 2 moves downward, it drives the connecting rod 5 fixed at the bottom to move downward. The downward movement of the connecting rod 5 drives the lower pressure plate 6 fixed at the other end to move downward. When the lower pressure plate 6 moves downward to a certain position, it contacts the surface of the gas cylinder. At this time, the lower pressure plate 6 continues to move downward. At this time, the support block 77 is subjected to the squeezing force and slides downward. At the same time, the compression return spring 76 is in a suitable tension state. At this time, the operator turns off the transmission motor 71, so that the lower pressure plate 6 no longer squeezes the gas cylinder, thus completing the squeezing of the gas cylinder and effectively clamping it to avoid shaking.

[0037] like Figures 1-5 As shown, this invention illustrates an assembly fixture for a composite gas cylinder in another embodiment. An adjustable clamping mechanism 8 is provided on the side of the hollow plate 74. The adjustable clamping mechanism 8 includes a hollow strip 81, which is fixedly connected to the side of the hollow plate 74. A connecting motor 82 passes through the side of the hollow strip 81. A bidirectional screw 83 is fixedly connected to the end of the output shaft of the connecting motor 82. A threaded block 84 is threadedly connected to the circumferential surface of the bidirectional screw 83. A rectangular plate 85 is fixedly connected to the top of the threaded block 84. A suction cup 86 is fixedly connected to the side of the rectangular plate 85. The above design facilitates effective clamping according to the length of the gas cylinder.

[0038] In some examples, an air nozzle 87 is fixedly connected to the outer surface of the suction cup 86, and a slide plug 88 is inserted into the inner wall of the air nozzle 87. The design of the slide plug 88 facilitates the rapid inflation of the inside of the suction cup 86.

[0039] The side section of the hollow bar 81 is set to be concave, and the number of threaded blocks 84 is set to four. The design of the hollow bar 81 is conducive to the stable operation of the connected motor 82.

[0040] The number of rectangular plates 85 is set to four, and the number of suction cups 86 is set to four. Setting the number of suction cups 86 to four is beneficial for clamping both ends of the gas cylinder.

[0041] The side section of the lower pressure plate 6 is set to be semi-circular, and the number of lower pressure plates 6 is set to two. Setting the number of lower pressure plates 6 to two is beneficial to clamp two gas cylinders at one time.

[0042] For example, such as Figures 1-5As shown, after the gas cylinder is clamped from top to bottom, the operator starts the connecting motor 82 that runs through the side of the hollow strip 81. At the same time, the double-headed screw 83 fixed at the end of the output shaft rotates. The rotation of the double-headed screw 83 causes the two sets of threaded blocks 84 threaded to the circumferential surface to move relative to each other. When the two sets of threaded blocks 84 move closer to each other, they cause the rectangular plate 85 fixed at the top to move closer to each other, thereby causing the suction cups 86 fixed on the side of the rectangular plate 85 to move closer to each other and contact the two ends of the gas cylinder, thus adsorbing onto the two ends of the gas cylinder. Finally, when the clamping state of the two ends is about to be released, the operator pulls out the sliding plug 88 inserted into the air nozzle 87, thereby causing air to rush into the suction cup 86, so that the suction cup 86 no longer adsorbs onto the two ends of the gas cylinder.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
