The utility model solves the problem that a large amount of smoke and dust will be generated during welding. Although people will wear protective equipment, they will inevitably inhale the smoke and dust into the body. The smoke and dust generated by welding will endanger human health. At the same time, these smoke and dust will diffuse into the air, pollute the air environment, have poor practicality, and are not conducive to actual use.

In addition, the L-shaped bracket cannot automatically adjust its position as the smoke concentration changes, and the fan cannot efficiently absorb the smoke, resulting in an increase in the smoke concentration in the working area. Therefore, a mechanical design and manufacturing welding fixture is proposed to solve the above-mentioned problems. Utility Model Content

[0035] In order to extract the smoke, a smoking device is provided on the outer surface of the frame 1. The smoking device includes a fan 7. The smoke is extracted when the fan 7 is started.

[0036] In order to improve the rotation stability of the screw 51, the smoking device also includes a motor 5, which is fixedly mounted on the outer surface of the frame 1, and the output shaft of the motor 5 is fixedly mounted with the screw 51. The screw 51 is rotatably connected to the inner wall of the frame 1 through a bearing. The motor 5 is fixedly mounted on the frame 1 to fix it, and the output shaft of the motor 5 is fixedly mounted on the screw 51 to drive the screw 51 to rotate. The screw 51 is rotatably connected to the frame 1 through a bearing. While it is fixed, its rotation does not affect the frame 1, so as to improve the rotation stability of the screw 51.

[0037] The movable rod 6 is connected to the inner wall of the groove of the frame 1 by a threaded connection with the limit block 62, and the outer surface of the limit block 62 is slidably connected to the inner wall of the groove of the movable rod 6, and the support frame 61 is slidably inserted in the inner wall of the groove of the movable rod 6. The inner wall of the groove of the movable rod 6 is threadedly connected to the limit block 62. The outer surface of the limit block 62 is slidably inserted in the inner wall of the groove of the movable rod 6, and the screw 51 is threadedly connected to the movable rod 6 to drive it to rotate and move. However, since the movable rod 6 is slidably connected to the frame 1, it is limited so that it can only move. The movable rod 6 is slidably inserted in the support frame 61 to drive it to move synchronously without affecting its lifting, so that the height of the fan 7 can be adjusted according to the workpiece passing through the support frame 61. The movable rod 6 is threadedly connected to the limit block 62, and the movable rod 6 is slidably inserted in the limit block 62, and the limit block 62 contacts the support frame 61. The staff rotates the movable block 41 to drive it to move in the slidingly inserted movable rod 6, thereby adjusting the tightness of the support frame 61.

[0038] In order to maintain the air quality in the welding area, a fan 7 is fixedly installed on the inner wall of the support frame 61, and the air inlet of the fan 7 is fixedly connected to a smoking pipe 71, and the air outlet of the fan 7 is fixedly connected to a smoke outlet pipe 72 with a filter layer. A smoke sensor 73 is fixedly installed on the outer surface of the support frame 61. The support frame 61 and the fan 7 are fixedly installed and fixed. The air inlet of the fan 7 sucks the smoke generated during welding through the fixedly connected smoking pipe 71, and then discharges it into the air through the smoke outlet pipe 72 fixedly connected to it. The filter layer of the smoke outlet pipe 72 filters the smoke. The smoke sensor 73 fixedly installed on the support frame 61 is electrically connected to the motor 5. The position of the smoke is sensed by the smoke sensor 73, and the motor 5 is started to drive the screw 51 to rotate, thereby adjusting the position of the fan 7 to maintain the air quality in the welding area.

[0039] By setting up a smoking device, smoke is sucked out, and the motor 5 drives the screw 51 to rotate, so that the moving rod 6 threadedly connected to the screw 51 moves on the slidingly connected frame 1. The staff rotates the moving block 41 to drive it to move in the slidingly inserted moving rod 6, so as to adjust the tightness of its fixation to the support frame 61. The smoking pipe 71 fixedly connected to the fan 7 sucks the smoke generated during welding, and then discharges it into the air through the smoke outlet pipe 72. The filter layer of the smoke outlet pipe 72 filters the smoke, and the smoke sensor 73 senses the position of the smoke, and starts the motor 5 to drive the screw 51 to rotate, so as to adjust the position of the fan 7 and maintain the air quality in the welding area. This solves the technical problem that when performing mechanical design, the L-shaped bracket cannot automatically adjust its position as the smoke concentration changes, and the fan 7 cannot efficiently absorb the smoke, resulting in an increase in the smoke concentration in the working area.

[0040] Working principle: When the workpiece needs to be fixed, the staff puts the workpiece on the frame 1 and starts the electric push rod 2. The extension of its telescopic rod drives the mobile frame 21 fixedly installed therewith to move on the slidingly connected frame 1. The deflection rod 3 rotatably connected to the mobile frame 21 and the connecting rod 32 rotatably connected to the moving block 41 drive the fixed block 31 rotatably connected to both to move. The fixed block 31 can deflect itself according to the shape of the workpiece. Similarly, the deflection block 42 rotatably connected to the frame 1 can also deflect itself according to the outer surface of the workpiece. The two cooperate with each other to fix the workpiece, and the spring 4 fixedly installed with the moving block 41 and the mobile frame 21 can reset itself after the moving block 41 moves.

[0041] When it is necessary to deal with the smoke generated during welding, the staff rotates the limit block 62 threaded on the moving rod 6 to move it in the sliding moving rod 6, thereby releasing the fixation of the support frame 61 slidably inserted in the moving rod 6. When the fan 7 is adjusted to a suitable height through the support frame 61, the limit block 62 is rotated again to fix the support frame 61. The smoke sensor 73 fixedly installed on the support frame 61 detects the concentration of the smoke, thereby starting the motor 5 to drive the screw 51 to rotate, so that the moving rod 6 threadedly connected thereto moves on the slidingly connected frame 1, thereby adjusting the position of the fan 7. The air inlet of the fan 7 sucks the smoke through the fixedly connected smoking pipe 71, and then discharges it into the air through the fixedly connected smoking pipe 72. The filter layer of the smoking pipe 72 filters the smoke.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
