The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0025] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0026] The embodiment of the present invention provides a vehicle body welding fixture upper part detection alarm device, such as Figure 1-7 As shown, it includes a bottom plate 1, a bracket 2 is installed on the upper end of the bottom plate 1, an electric slide 3 is installed on the front side of the bracket 2, a welding machine 4 is installed on the lower side of the electric slide 3, two groups of clamp bodies 5 are symmetrically installed on the surface of the bottom plate 1, fixing plates 6 are installed on the left and right sides of the bracket 2, and connecting plates 7 are installed on the sides of the two groups of fixing plates 6 away from each other, and the other end of the connecting plate 7 is connected to a connecting frame 8, a mounting frame 10 is installed on the lower side of the connecting frame 8, and a detection device 11 is installed on the lower side of the mounting frame 10, and a notch is opened inside the fixing plate 6, and the notch A screw rod 12 is rotatably installed in the mouth, a screw sleeve 13 is sleeved on the outside of the screw rod 12, a connecting block 14 is connected to the side of the screw sleeve 13, the outer end of the connecting block 14 is connected to the connecting plate 7, the connecting frame 8 is hingedly connected to the connecting plate 7, the connecting frame 8 and the connecting plate 7 are positioned and fixed by a damping bolt 9, and the detection device 11 is provided with two groups and is respectively located above the two groups of clamp bodies 5. When the device is used, the sheet metal parts to be welded can be placed between the two groups of clamp bodies 5 respectively. At this time, the detection device 11 detects the type of the sheet metal parts. When an error occurs in the loading of sheet metal parts, the detection device 11 issues an alarm to remind the staff to correct it. Subsequent welding work can only be carried out when the sheet metal parts are loaded correctly. The device avoids damage to parts and useless welding of parts caused by manual wrong loading and identification alarms of different parts by adding the detection device 11. In addition, the detection device 11 is installed on the side of the bracket 2 through the fixing plate 6. Since the heights of different sheet metal parts are different, when it is necessary to detect sheet metal parts of different heights, the screw rod 12 can be rotated, and the screw sleeve 13 slides up and down under the action of the thread on the surface of the screw rod 12, so that the height of the detection device 11 changes. Through this setting, the height adjustment of the detection device 11 can be realized, and the adjustment method is simple, convenient and easy to operate, thereby improving the practicality of the detection device 11. By providing a connecting frame 8, the connecting frame 8 is hingedly connected to the connecting plate 7 and is positioned and fixed by the damping bolt 9. The detection device 11 can be pushed left and right to adjust the camera angle, so that the detection device 11 is more comprehensive to use and has higher detection accuracy.

[0027] The detection device 11 is electrically connected to the power supply, and a relay is installed between the detection device 11 and the fixture control switch. The two groups of detection devices 11 open and close the fixture control switch by controlling the two groups of relays. The power supply and the fixture control switch work through the opening and closing of the two groups of relays. The two groups of relays must be closed at the same time to be energized. When the detection device 11 detects an error in the loading of a sheet metal part, the relay between one of the detection devices 11 and the fixture control switch is in a power-off state, so the fixture cannot perform subsequent operations, thereby further improving the safety and standardization of the operation under the condition of an alarm reminder.

[0028] An indicator light 24 is installed on the front side of the detection device 11. The indicator light 24 indicates red and green alternately. A speaker 25 is installed inside the detection device 11. The speaker 25 uses a buzzer sound effect. After the detection device 11 detects an error, the indicator light 24 lights up red to remind you, and the speaker 25 emits a buzzer to alarm. The warning effect of the detection device 11 is improved by the double alarm.

[0029] The detection system in the detection device 11 includes mechanical identification of sheet metal parts and human skin. In addition to identifying sheet metal parts, the detection device 11 can also identify human skin. In order to ensure the safety of the clamp, the clamp cannot work when the skin of the human hand is close to the clamp to prevent the clamp from pinching the worker's hand.

[0030] The connecting plate 7 is hingedly connected to the connecting block 14, and the connecting plate 7 and the connecting block 14 are positioned and fixed by the damping bolt 9. The connecting plate 7 and the connecting block 14 are hingedly connected. Through this arrangement, the connecting plate 7 can fluctuate up and down, thereby adaptively adjusting the detection position of the detection device 11 according to the sheet metal, making the adjustment and use of the detection device 11 more flexible.

[0031] A T-shaped notch is provided on the lower side of the mounting frame 10, and a card plate 15 is installed on the top of the detection device 11. The card plate 15 is installed on the lower side of the mounting frame 10 by sliding and plugging. A groove is provided on the top of the mounting frame 10, and a pull rod 16 is slidably installed in the groove. A card block 17 is installed on the inner end of the pull rod 16. A card slot matching the card block 17 is provided on the upper surface of the card plate 15. The card block 17 passes through the mounting frame 10 and is carded in the card slot of the card plate 15. A pull ring 18 is connected to the outer end of the pull rod 16, and a spring is sleeved on the outer side of the pull rod 16. The spring 19, the mounting frame 10 and the card plate 15, the detection device 11 and the mounting frame 10 are connected through the card plate 15, and the card plate 15 is installed under the mounting frame 10 by sliding and plugging and fixed by the spring 19 and the card block 17. When the detection device 11 needs to be removed, the pull ring 18 can be pulled to pull the card block 17 out of the card slot of the detection device 11. At this time, the detection device 11 can be pulled horizontally to pull the card plate 15 out of the card slot under the mounting frame 10. This installation method can make the disassembly, assembly and replacement of the detection device 11 more convenient.

[0032] The block 17 is set to be trapezoidal, and the inclined surface of the block 17 faces the outside of the slot of the mounting frame 10. By setting the block 17 to be trapezoidal, this setting can enable the card plate 15 to push the block 17 upward when it is inserted, thereby making the installation of the detection device 11 more convenient and labor-saving.

[0033] Limiting grooves 20 are provided on the left and right sides of the detection device 11, and two groups of limiting blocks 21 are inserted in the limiting grooves 20. Fixing frames 22 are installed on the outer sides of the two groups of limiting blocks 21, and a protective plate 23 is installed between the two groups of fixing frames 22. The protective plate 23 is located outside the camera of the detection device 11. The protective plate 23 is made of transparent glass. By providing the protective plate 23, the protective plate 23 is located outside the camera of the detection device 11 to protect it, avoiding damage to the mirror surface of the camera due to external factors during welding. In addition, the protective plate 23 is slidably installed through the limiting blocks 21. This installation method can make the disassembly, assembly and replacement of the protective plate 23 more convenient and labor-saving.
