Description

Technical Field

[0001] The utility model relates to the technical field of cylinder production and manufacturing, in particular to a cylinder weld leak testing device. Background Art

[0002] In industrial production, the cylinder is a key component of many equipments, and its quality directly affects the stability and safety of the whole system. Especially in the fields of pressure vessels, hydraulic systems, chemical equipment, etc., the sealing of the cylinder is very important. Therefore, during the manufacturing process, especially after the welding process is completed, the cylinder must undergo strict leak testing to ensure the tightness and reliability of the weld.

[0003] The traditional method of leak testing for cylinder welds is usually to immerse the welded portion of the cylinder end in water after the weld is completed, and observe whether bubbles are generated to determine whether there is a leak. Although this method is intuitive and effective, it has some significant shortcomings during operation. First, due to the large size and weight of the cylinder, the process of manually carrying it to the side of the sink and standing it up is very laborious, which not only increases the labor intensity of the workers, but also may bring safety risks. Secondly, manual operation is inefficient, and only one cylinder can be tested at a time, which cannot meet the high-efficiency and large-scale production requirements of modern production lines, which undoubtedly limits production efficiency and cost control.

[0004] To this end, the present application specifically proposes a cylinder weld leak testing device to solve the above technical problems. Utility Model Content

[0005] The main purpose of the utility model is to solve the above-mentioned shortcomings and provide a cylinder weld leak testing device to assist manual labor in simultaneously standing up multiple cylinders and immersing the weld parts into water, thereby reducing manual labor intensity and improving detection efficiency.

[0008] Furthermore, two cross braces are symmetrically arranged on the supporting frame, and a mounting cross plate is arranged between the two cross braces.

[0009] Furthermore, the positioning assembly includes a plurality of supports evenly arranged on the cross brace rod and a clamping member fixed on the mounting cross plate, which is used to clamp and fix the cylinder barrel on the supports. The supports on the two cross braces correspond one to one, and the two corresponding supports form a group to jointly support one cylinder barrel.

[0010] Furthermore, the clamping member includes a plurality of spinning cylinders fixedly arranged on the mounting cross plate and a pressing block fixedly arranged on the top of the spinning cylinder, the spinning cylinder is located between two groups of the supports, and each two groups of the supports share one pressing block.

[0011] Furthermore, a first trapezoidal groove is formed on the support, and a second trapezoidal groove is symmetrically formed on the pressing block.

[0012] Furthermore, a roller group is fixedly provided at the bottom of the support rod, and the roller group is limitedly slidably inserted in the slide rail.

[0013] The beneficial effects of the utility model are embodied in:

[0014] The utility model utilizes a positioning assembly to clamp a plurality of cylinder barrels on the top surface of a supporting frame at the same time, and drives one end of the supporting frame to flip into the water tank through a telescopic cylinder and a support rod hingedly arranged at the bottom of the supporting frame, until the weld of the cylinder barrel on the supporting frame is completely submerged in water, and the support rod slides along the slide rail during the flipping process of the supporting frame, cooperates with the telescopic cylinder, and provides a stable support for the supporting frame while driving it to flip.

DETAILED DESCRIPTION

[0023] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] like Figure 1-6 As shown, the utility model provides a cylinder weld leak testing device, comprising:

[0025] Water tank 1;

[0026] Two telescopic cylinders 2 are symmetrically arranged on one side of the outside of the water tank 1;

[0027] Two slide rails 3 are symmetrically arranged at the bottom of the inner cavity of the water tank 1;

[0028] Two support rods 4, the bottom of which is slidably inserted in the slide rail 3;

[0029] The supporting frame 5 is hinged to the top of the support rod 4 and the telescopic cylinder 2;

[0030] The positioning assembly 6 is fixedly arranged on the top surface of the supporting frame 5 and is used for installing the cylinder 7 .

[0031] Before use, first fill the water tank 1 with water, and adjust the supporting frame 5 to be horizontal by controlling the extension length of the telescopic cylinder 2, then point the end of the cylinder 7 to be tested for leaks toward the water tank 1 and install it on the positioning assembly 6, start the telescopic cylinder 2 to extend it, and the telescopic cylinder 2 drives one end of the supporting frame 5 to be immersed in the water tank 1, thereby driving the end of the cylinder 7 fixed on the supporting frame 5 to be tested for leaks to be immersed in the water tank 1. The tester determines the welding quality by observing whether bubbles emerge from the weld immersed in water. In this process, the supporting frame 5 drives the support rod 4 to slide on the slide rail 3 to ensure that the supporting frame 5 can still be well supported while tilting and flipping, so as not to tip over at will.

[0032] In one embodiment, two cross braces 9 are symmetrically arranged on the support frame 5, and a mounting cross plate 10 is arranged between the two cross braces 9. This design not only strengthens the overall structural stability of the support frame 5, but also provides a platform for the subsequent installation of the positioning assembly 6.

[0033] In one embodiment, the positioning assembly 6 includes a plurality of supports 61 evenly arranged on the cross brace rod 9 and a clamping member 62 fixedly arranged on the mounting cross plate 10, which is used to clamp and fix the cylinder 7 on the supports 61. The supports 61 on the two cross braces 9 correspond one to one, and two corresponding supports 61 form a group to jointly support a cylinder 7.

[0034] With this design, the two ends of the cylinder 7 are respectively overlapped on two supports 61 of the same group, ensuring that the cylinder 7 can be firmly supported, and the clamping piece 62 firmly presses and fixes the cylinder 7 on the support 61, so that it is difficult for the cylinder 7 to slide off the support 61 when it is tilted. Since there are multiple groups of supports 61, multiple cylinders 7 can be installed on the supporting frame 5 at the same time for synchronous leak testing.

[0035] In one embodiment, the clamping member 62 includes a plurality of spinning cylinders 621 fixedly disposed on the mounting cross plate 10 and a pressing block 622 fixedly disposed on the top of the spinning cylinder 621 . The spinning cylinder 621 is located between two groups of supports 61 , and each two groups of supports 61 share one pressing block 622 .

[0036] Designed like this, Figure 3 As shown, when the cylinder 7 is not clamped, the pressing block 622 is perpendicular to the cross brace 9, avoiding interference with the placement process of the cylinder 7 and facilitating the installation of the cylinder 7 on the support 61; when it is necessary to compact the installed cylinder 7, the spinning cylinder 621 drives the pressing block 622 to rotate to be parallel to the cross brace 9, and drives the pressing block 622 to be pressed downward, so that the pressing block 622 simultaneously compacts the cylinder 7 on both sides.

[0037] In one embodiment, the support 61 is provided with a first trapezoidal groove 11, and the pressing block 622 is symmetrically provided with a second trapezoidal groove 12. This design enables the support 61 and the pressing block 622 to clamp cylinders 7 of different diameters, thereby expanding their application range.

[0038] In one embodiment, a roller set 8 is fixedly provided at the bottom of the support rod 4, and the roller set 8 is inserted in the slide rail 3 in a limited sliding manner. This design reduces the friction between the support rod 4 and the slide rail 3 when relative sliding occurs, making the slide of the support rod 4 smoother.

[0039] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.

[0040] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0041] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, "multiple" means more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.
