Referring to fig. 1-7, a device for detecting the gas tightness of a metal can body is shown, which comprises a workbench 1, wherein a lifting frame 2 is arranged on the workbench 1, and a liftable pressurization detection mechanism 3 is arranged on the lifting frame 2; the pressurization detection mechanism 3 comprises a lifting plate 31 which can be vertically lifted on the lifting frame 2, a driving air cylinder 32 arranged on the lifting plate 31, a pressure plate 33 arranged below the lifting plate 31 and a contact pin 34 arranged below the pressure plate 33; the pressure plate 33 is driven to lift by the driving cylinder 32, a communicated air path is arranged in the pressure plate 33 and the contact pin 34, an air inlet joint 331 is arranged on the pressure plate 33, and an air outlet hole 341 is arranged on the contact pin 34; the air intake joint 331 is supplied with air through a pipe (not shown) to which a pressure transmitter (not shown) is connected.
Specifically, when the gas tightness of the metal can body needs to be detected, the pressurizing detection mechanism 3 is positioned at a proper position on the lifting frame 2, so that the metal can body can be accommodated between the pressurizing detection mechanism 3 and the workbench 1; a worker places a metal can body on the workbench 1, so that the mouth of the metal can body corresponds to the upper contact pin 34, the driving air cylinder 32 drives the pressure plate 33 to descend on the lifting plate 31, the contact pin 34 is inserted from the mouth of the metal can body, and a seal is formed between the pressure plate 33 and the mouth of the metal can body to avoid air leakage; gas is supplied from the gas inlet joint 331 through a pipeline, and enters the metal tank body from the gas outlet 341 on the inserting pin 34; the pressure is sensed by the pressure transmitter and the electronic reading can be viewed from a display screen or other display device carried by the pressure transmitter.
It should be noted that, because the metal can body air tightness detection device can be used for detecting the air tightness of metal can bodies of different sizes, when detecting a metal can body of a certain size, the pressurizing detection mechanism 3 is firstly moved to a height slightly higher than that of the metal can body by the lifting frame 2, and then when detecting the metal can bodies of the certain size in batch, only the driving cylinder 32 is needed to drive the pressure plate 33 to lift, and the lifting frame 2 does not need to work; when a metal can body with another size needs to be detected, the lifting frame 2 moves the pressurizing detection mechanism 3 to a proper height; since the motor 24 needs to move the whole of the pressurization detection mechanism 3, the driving cylinder 32 only needs to move the components such as the pressure plate 33 and the contact pin 34, and the energy consumption of the motor 24 is higher than that of the driving cylinder 32, the motor 24 is operated only when metal cans of different sizes are detected in order to save energy; when metal can bodies with the same size are detected in batches, the driving cylinder 32 only needs to work. In addition, the motor 24 is inconvenient for keeping the pressure plate 33 tightly pressed on the bottle mouth of the metal can body, and when the air pressure in the metal can body is increased, gas is easy to leak between the bottle mouth and the pressure plate 33; while the actuating cylinder 32 facilitates the pressure plate 33 to remain pressed against the mouth of the metal can.
Therefore, the pressure detection mechanism 3 is driven by the lifting frame 2 to automatically pressurize the metal tank body, and the pressure transmitter is used for detecting the air pressure; compared with manual detection, the detection efficiency is greatly improved; in addition, the pressure transmitter is used for detecting air pressure, so that the problem that the reading of a pressure gauge is inaccurate by workers can be avoided, the requirement on experience of the workers is low, the labor cost is reduced, and the detection effect is improved.
In the above embodiment, in order to ensure the sealing performance between the pressure plate 33 and the mouth of the metal can, referring to fig. 3 and 4, a sealing rubber pad 35 is arranged at the bottom of the pressure plate 33. In order to make the lifting of the pressure plate 33 more stable, the driving cylinder 32 is arranged above the lifting plate 31, a piston rod of the driving cylinder 32 passes through the lifting plate 31 and then is connected with a connecting plate 36, and the pressure plate 33 is fixed at the bottom of the connecting plate 36; the connecting plate 36 is provided with a first guide rod 37 vertically arranged, and the first guide rod 37 is slidably connected with the lifting plate 31.
In the above embodiment, referring to fig. 1, 2 and 5, the lifting frame 2 includes two vertically disposed screws 22 disposed at two sides of the pressurization detection mechanism 3, and the screws 22 are in threaded connection with the lifting plate 31; a second guide rod 23 which is vertically arranged is arranged outside the screw rod 22, and the second guide rod 23 is connected with the lifting plate 31 in a sliding manner; one screw 22 is driven to rotate by a motor 24, and the two screws 22 realize synchronous rotation by a synchronous belt. The lifting frame 2 further comprises a shell 21 arranged outside the screw rod 22 and the guide rod; the shell 21 is provided with a scale bar 211, and the lifting plate 31 is provided with a pointer 311 correspondingly pointing to the scale bar 211. In this way, the lifting range of the lifting plate 31 can be visually seen through the pointer 311 and the scale bar 211.
In the above-mentioned solution, in order to facilitate rapid detection when detecting metal can bodies of different sizes, referring to fig. 6 and 7, a turntable 4 capable of rotating along a vertical axis is provided on the worktable 1; at least three T-shaped grooves 41 are arranged on the rotary table 4 along the radial direction, slidable T-shaped nuts 42 are arranged in the T-shaped grooves 41, part of each T-shaped nut 42 protrudes out of the upper surface of the rotary table 4, and the T-shaped nuts 42 are fixed in the T-shaped grooves 41 through bolts (not shown); all the T-shaped nuts 42 are connected into an arc taking the center of the turntable 4 as a circle, and the radian of the arc is less than 180 degrees; the center of the rotary table 4 vertically corresponds to the pin 34. Specifically, when the metal tank bodies need to be detected in batches, the positions of the T-shaped nuts 42 on the T-shaped grooves 41 can be adjusted firstly, the lengths of all the T-shaped nuts 42 from the circle center of the rotary table 4 are equal, then the metal tank bodies are arranged on the rotary table 4, and the outer walls of the metal tank bodies are abutted against all the T-shaped nuts 42, so that the bottle mouths of the metal tank bodies can quickly correspond to the inserting pins 34, the metal tank bodies can be conveniently and quickly placed, and the detection efficiency is improved.
Wherein, all the T-shaped nuts 42 are connected into an arc taking the center of the turntable 4 as a circle, and the radian of the arc is less than 180 degrees; the T-shaped nut 42 is prevented from blocking the metal can body from sliding on the rotary table 4 to the circle center of the rotary table 4. The turntable 4 can rotate, and when the position of the T-shaped nut 42 on the T-shaped groove 41 needs to be adjusted, the turntable 4 can be rotated to enable the T-shaped groove 41 to turn to the front of a worker, so that the operation of the worker is facilitated, and the situation that the worker needs to move the position of the worker is avoided; in the above process, when the position of the T-shaped nut 42 on the T-shaped groove 41 needs to be fixed, the bolt on the T-shaped nut 42 is screwed, and the end of the bolt abuts against the bottom surface of the T-shaped groove 41, so that the T-shaped nut 42 is fixed. Wherein, in order to facilitate the rotation of the turntable 4, referring to fig. 6, the periphery of the turntable 4 is provided with a rotation handle 43.
