Description

Technical Field

[0001] This utility model relates to the field of gas cylinder detection technology, and in particular to a gas cylinder neck detection device. Background Technology

[0002] Cylinder neck detection equipment is a specialized device used during the manufacturing or maintenance of cylinders to detect and verify the quality (such as dimensional accuracy, sealing performance, and structural integrity) of the neck. Its core purpose is to ensure that the neck of the cylinder meets safety standards after necking and to avoid risks such as leakage and structural failure caused by necking defects.

[0003] When testing the sealing performance of a gas cylinder cap, it is typically placed on a processing table and connected to an external inflation pipe via a threaded connection to inflate the cylinder with a suitable amount of gas. However, this method does not provide a direct visual indication of whether the cap is leaking, thus reducing the efficiency of the device in testing the cap. Utility Model Content

[0004] This utility model provides a cylinder neck detection device to solve the problem that when the cylinder is placed on a processing table and connected to an external inflation pipe to fill it with an appropriate amount of gas, the detection process cannot directly reflect whether there is a leak at the cylinder neck, thus reducing the device's efficiency in detecting cylinder necks.

[0005] This utility model provides a gas cylinder neck detection device, including a processing table. A controller is fixedly installed on the front side of the processing table near the other side. A bracket is fixedly installed on one side of the processing table, and a spraying component is provided at the bottom of the bracket.

A connector is threaded to the top of the gas cylinder body, and a connecting pipe is inserted into the top of the connector. A valve is provided on the outer periphery of the connecting pipe, and a pressure gauge is inserted into one side of the connecting pipe. A limit component is provided on the top of the load-bearing plate.

[0006] The spraying assembly includes an L-shaped frame fixedly installed at the top of the inner cavity of the bracket near the rear side and a mounting plate fixedly installed at the front side of the L-shaped frame near the middle position. A servo motor B is fixedly installed at the front side of the L-shaped frame near the middle position. A reciprocating screw is attached to the end of the power output shaft of the servo motor B.

A liquid storage tank is fixedly installed at the top of the bracket. A pump body is fixedly installed at the top of the bracket near the other side. A conduit is inserted between the pump body and the liquid storage tank. A hose is inserted between the pump body and the atomizing head.

[0007] Preferably, a limiting block B is fixedly installed on the rear side of the lead screw nut, and the top of the limiting block B movably passes through the limiting rod B, and the top and bottom ends of the limiting rod B are fixedly connected to the bottom of the inner cavity of the mounting plate and the L-shaped frame, respectively.

[0008] Preferably, a disc is provided at the bottom of the load-bearing plate, and two electric telescopic rods are hinged to the top of the disc near one side. The top ends of the electric telescopic rods are hinged to the load-bearing plate. Connecting shafts are rotatably connected to the front and rear sides of the load-bearing plate near the other side. Rectangular plates are fixedly installed at opposite ends of the connecting shafts, and the bottoms of the rectangular plates are fixedly connected to the disc. A servo motor A is fixedly installed at the middle of the top of the processing table, and the power output shaft of the servo motor A is fixedly connected to the disc.

[0009] Preferably, support columns are fixedly installed on both sides of the bottom of the disc, a limiting groove is opened on the top of the processing table, and the bottom end of the support column is slidably connected to the inner cavity of the limiting groove.

[0010] Preferably, the limiting component includes a fixed plate fixedly installed on the top of the load-bearing plate near both sides and a threaded rod rotatably connected to the fixed plate on one side. The other end of the threaded rod movably passes through the adjacent fixed plate and is fixedly installed with a knob. Threaded sleeves are threadedly connected to the outer periphery of the threaded rod near both ends.

A compression spring is movably sleeved on the outer periphery of the compression telescopic rod, and the two ends of the compression spring are fixedly connected to the clamping block and the movable plate, respectively. Beneficial effects

[0013] Considering that it is placed on the processing table and connected to the external inflation pipe to fill the cylinder with an appropriate amount of gas, the detection process cannot directly reflect whether there is a leak at the cylinder neck, which reduces the efficiency of the device in detecting the cylinder neck.

[0014] This invention, by incorporating a spraying component, allows the screw nut, movable around the outer periphery of the reciprocating screw, to move up and down during the rotation of the reciprocating screw. Soapy water is then evenly sprayed onto the outer periphery of the cylinder body via an atomizing head, enabling clear observation of the cylinder's airtightness test results and improving the efficiency of the airtightness test. Furthermore, by incorporating a limiting component, the rotation of the threaded rod allows the two threaded sleeves threaded to the outer periphery of the threaded rod to move to opposite sides. This, in turn, allows the movable plates fixed to the threaded sleeves to move to opposite sides, thereby securing the cylinder body with clamping blocks and improving the stability of the cylinder body during the testing process.

Rectangular plates 72 are fixedly installed on the opposite end of each connecting shaft 73. The bottom of each rectangular plate 72 is fixedly connected to the disc 74. A servo motor A75 is fixedly installed at the middle of the top of the processing table 1. The power output shaft of the servo motor A75 is fixedly connected to the disc 74.

[0036] It is advantageous that, with the activation of the electric telescopic rod 71, the angle of the load-bearing plate 7 can be deflected, thereby facilitating the viewer's observation, and the servo motor A75 at the bottom of the disc 74 can rotate the disc 74.

[0037] Support columns 741 are fixedly installed on both sides of the bottom of the disc 74. A limit groove 742 is opened on the top of the processing table 1, and the bottom end of the support column 741 is slidably connected to the inner cavity of the limit groove 742.

[0038] It is advantageous that by setting a support column 741 at the bottom of the disk 74, the stability of the disk 74 rotation can be improved.

[0039] The limiting component 8 includes a fixed plate 81 fixedly installed on the top of the load-bearing plate 7 near both sides and a threaded rod 82 rotatably connected to the fixed plate 81 on one side. The other end of the threaded rod 82 movably passes through the adjacent fixed plate 81 and is fixedly installed with a knob 86. Threaded sleeves 83 are threadedly connected to the outer periphery of the threaded rod 82 near both ends. Movable plates 84 are provided on the front side of each threaded sleeve 83, and several clamping blocks 85 are provided on the opposite side of each movable plate 84.

[0040] It is advantageous that by setting the limiting component 8, the two threaded sleeves 83 threadedly connected to the outer periphery of the threaded rod 82 can move to the opposite side under the rotation of the threaded rod 82, thereby enabling the movable plate 84 fixed on the threaded sleeve 83 to move to the opposite side, and thus enabling the cylinder body 4 to be fixed by the clamping block 85, thereby improving the stability of the cylinder body 4 during the detection process.

[0041] Limiting blocks A831 are fixedly installed on the rear side of threaded sleeve 83, and the opposite side of limiting blocks A831 moves through limiting rods A832, and the two ends of limiting rods A832 are fixedly connected to adjacent fixed plates 81 respectively.

[0042] It is advantageous that by setting the limit block A831 and the limit rod A832, the movement of the threaded sleeve 83 can be limited.

[0043] On the opposite side of the clamping block 85, a compression telescopic rod 851 is fixedly installed, and the opposite end of the compression telescopic rod 851 is fixedly connected to the adjacent movable plate 84. A compression spring 852 is movably sleeved on the outer periphery of the compression telescopic rod 851, and the two ends of the compression spring 852 are fixedly connected to the clamping block 85 and the movable plate 84 respectively.

[0044] It is advantageous that by setting up the compression telescopic rod 851 and the compression spring 852, the effect of the clamping block 85 in fixing the cylinder body 4 can be improved.

[0045] Working Principle: In use, the cylinder body 4 is first placed on top of the load-bearing plate 7. Then, the knob 86 can be rotated to rotate the threaded rod 82 fixed on the knob 86. The outer periphery of the threaded rod 82 has opposite external threads near both ends. Under the rotation of the threaded rod 82, the threaded sleeve 83 threaded to the outer periphery of the threaded rod 82 can move to the opposite side under the limitation of the limiting block A831 and the limiting rod A832. This allows the movable plate 84 fixed on the threaded sleeve 83 to move to the opposite side. The adjacent clamping block 85 can fix the cylinder body 4, and the compression telescopic rod 851 and compression spring 852 can improve the fixing effect of the cylinder body 4. Then, the operator can thread the connector 5 to the top of the cylinder body 4, and then connect the connecting pipe 6 to the external gas pipe to fill the cylinder body 4 with an appropriate amount of gas. The airtightness of the cylinder body 4 can be checked using a pressure gauge. After filling with an appropriate amount, the pump body 99 can be started via controller 2 to extract the soapy water from the storage tank 98 and input it into the inner cavity of the atomizing head 96 for spraying. When the power output shaft of the servo motor B93 rotates, the reciprocating screw 94 fixed at the end of the power output shaft of the servo motor B93 can rotate. This allows the screw nut 95, which moves around the reciprocating screw 94, to move up and down under the limit of the limit block B951 and the limit rod B952, so that soapy water can be sprayed evenly around the outer circumference of the cylinder body 4. During testing, the angle of the load-bearing plate 7 can be adjusted via controller 2. After adjusting to a suitable position, the servo motor A75 can also be started. The rotation of the power output shaft of the servo motor A75 drives the disc 74 fixed at the end of the power output shaft of the servo motor A75 to rotate, which makes it convenient to check the airtightness of the open part of the cylinder body 4.
