furthermore, due to the arrangement of the supporting columns 5, smoke dust and waste gas generated in the welding process can enter the negative pressure cavity 4 through the air exhaust holes 2 and are introduced into the purifying equipment through the exhaust pipe 9 on the vacuum pump 12, so that the smoke dust and the waste gas are prevented from being sucked into the lung by an operator to influence the body health of the operator, and meanwhile, because the supporting columns 5 are uniformly arranged on the surface of the welding table 1, gaps among the supporting columns 5 can be used for clamping plate-shaped parts, so that the plate-shaped parts can be vertically placed, and the plate-shaped parts can be favorably subjected to three-dimensional welding;
furthermore, when smoke and waste gas generated by welding pass through the interior of the air draft hole 2, partial smoke particles are deposited on the inner wall of the air draft hole 2, the interior of the air draft hole 2 is blocked for a long time, the bristles 29 on the dredging rod 25 can clean the inner wall of the air draft hole 2 when the dredging rod moves up and down, so that the blockage in the air draft hole 2 can be prevented, meanwhile, the dredging rod 25 can rotate around the axis of the dredging rod, and the cleaning effect on the inner wall of the air draft hole 2 is better;
in order to realize the rotation of the dredging rod 25 around the axis of the dredging rod, a spiral groove 30 is formed in the periphery of the dredging rod 25, a fixed guide rod 28 is arranged at the position, close to the bottom end, of the inner wall of the air suction hole 2, and the free end of the fixed guide rod 28 is located inside the spiral groove 30.
When the sealing plate 26 drives the dredging rod 25 to move up and down, the fixed guide rod 28 is always positioned inside the spiral groove 30 and is mutually connected with the spiral groove 30 in a sliding manner, the fixed guide rod 28 is fixed on the inner wall of the air draft hole 2, the dredging rod 25 is rotatably connected to the top of the sealing plate 26, and the fixed guide rod 28 plays a role in guiding the dredging rod 25 when the dredging rod 25 moves up and down, so that the dredging rod 25 is driven to rotate around the axis of the dredging rod 25, and the cleaning effect of the brush bristles 29 on the inner wall of the air draft hole 2 is better;
and the brush bristles 29 are spirally distributed along the track of the dredging rod 25 at the periphery of the dredging rod 25.
The brush hair 29 is the heliciform and distributes in dredging rod 25's periphery along dredging rod 25's orbit, not only can prevent that fixed guide bar 28 from leading to the fact the stopping to brush hair 29, avoid influencing dredging rod 25's rotation, brush hair 29 is that the spiral sets up better to the clean effect of 2 inner walls in induced draft hole simultaneously, also the brush hair 29 can carry the smoke and dust when cleaning to induced draft hole 2, prevent that the smoke and dust accumulation under the cleanness is in brush hair 29's clearance, simultaneously because brush hair 29 is less with the area of contact of 2 inner walls in induced draft hole, can reduce the frictional resistance between induced draft hole 2 and the brush hair 29
It should be noted that the brush bristles 29 of the present invention are preferably made of a fire-resistant material to prevent the brush bristles 29 from being burnt when sparks generated during welding fall into the inside of the ventilation hole 2, and the second monitoring sensor 27 may be a distance sensor, a camera, or the like.
The periphery of support column 5 is equipped with and is the deflection pole 7 that the annular was arranged around the axis of support column 5, and the top activity of deflection pole 7 articulates at the surface of support column 5, be equipped with the drive assembly that control deflection pole 7 deflected to the direction of keeping away from or being close to support column 5 on the support column 5, be equipped with induction assembly on the deflection pole 7, controller 11 electric connection is in induction assembly and drive assembly.
In actual operation, because the gap between the support columns 5 can be used for clamping a component, the welded frame can be tightly supported outside the support columns 5, so that the component is fixed, in order to enable the gap between the support columns 5 to be matched with the thickness of the component, the deflection rods 7 which can be far away from or close to the support columns 5 are arranged outside the support columns 5, when the deflection rods 7 are gradually far away from the support columns 5, the gap between two adjacent groups of support columns 5 is gradually reduced, the component can be clamped and fixed by the deflection rods 7 on the two adjacent groups of support columns 5, meanwhile, some hollow pipe fittings or frames can be sleeved outside the support columns 5, and at the moment, the deflection rods 7 can tightly support and fix the component when deflecting in the direction far away from the support columns 5;
when practical application, after the part was close to support column 5 a period, sensing assembly sensed the signal this moment to give controller 11 with the signal transmission, controller 11 will control drive assembly and start, and will deflect pole 7 to the direction of keeping away from support column 5, thereby can "press from both sides tight fixed" or "prop tightly fixedly" with the part, be favorable to fixing the work piece in vertical direction, thereby be convenient for "three-dimensional welding".
Specifically, the sensing assembly comprises a pressure sensor 20, a storage groove 23 and a first monitoring sensor 24, the storage groove 23 is located on the surface of the deflection rod 7 far away from the support column 5, the pressure sensor 20 and the first monitoring sensor 24 are arranged inside the storage groove 23, and the controller 11 is electrically connected to the pressure sensor 20 and the first monitoring sensor 24.
When the component is at a position close to the supporting column 5, the first monitoring sensor 24 on the deflecting rod 7 senses the existence of the component, when the time for which the component stays near the supporting column 5 exceeds a certain value (which is convenient for adjusting the position of the component and preventing the component from being fixed just close to the supporting column 5), the first monitoring sensor 24 transmits a signal to the controller 11, the controller 11 controls the driving assembly to start, and deflects the deflecting rod 7 away from the supporting column 5, so as to clamp or brace the component, in order to prevent the component from being extruded and deformed, the pressure sensor 20 is arranged outside the deflecting rod 7, when the pressure sensor 20 reaches a certain pressure value, the pressure sensor 20 transmits a signal to the controller 11, and the controller 11 controls the driving assembly to stop continuously deflecting the deflecting rod 7 away from the supporting column 5;
it should be noted that, the first monitoring sensor 24 may be a distance sensor, and the like, and the sensitivity of the first monitoring sensor 24 is weak, that is, the first monitoring sensors 24 on two adjacent deflection rods 7 do not mutually sense, but only sense the components located between the deflection rods 7, so as to ensure that the deflection rods 7 move in the direction away from the support column 5 only when clamping or tightening the components.
More specifically, the driving assembly comprises a penetrating hole 3 and a push rod 18, the penetrating hole 3 is located at a position corresponding to the deflecting rod 7 on the periphery of the support column 5, the penetrating hole 3 is communicated with the inside of the sliding cavity 15, the push rod 18 is horizontally inserted into the penetrating hole 3, one end, far away from the deflecting rod 7, of the push rod 18 is fixedly connected with a convex rod 19, the convex rod 19 is fixedly connected with the inner wall of the sliding cavity 15 through a compression spring, and a pushing assembly for pushing the push rod 18 to move towards the direction close to the deflecting rod 7 is arranged inside the sliding cavity 15.
When the pushing assembly drives the pushing rod 18 to gradually move towards the direction approaching the deflecting rod 7, the pushing rod 18 will push the deflecting rod 7 to deflect towards the direction away from the supporting column 5, and when the pushing rod 18 gradually moves towards the direction away from the deflecting rod 7, the deflecting rod 7 will also move towards the direction approaching the supporting column 5 under the self-gravity.
