DETAILED DESCRIPTION
[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0028] Reference Figure 1-5 A frame welding device for an excavator cab comprises a welding table 1, a cab frame body 11 is provided above the welding table 1, a clamping cylinder 2 is provided on the welding table 1, a clamping plate 21 is provided on the clamping cylinder 2, a table leg 3 is provided on the welding table 1, a bottom support plate 4 is provided on the table leg 3, a dust extraction pump 41 and a dust storage box 5 are provided on the bottom support plate 4, a dust conveying main pipe 6 is provided on the dust conveying main pipe 6, a connecting sleeve 61 is provided on the dust extraction plate 62, and a dust guide filter plate 51 is provided in the dust storage box 5;
[0029] The dust storage box 5 is provided with a rotating shaft 53, a box baffle 7 is provided on the rotating shaft 53, a threaded pin 71 is provided on the box baffle 7, and a cleaning opening 52 is opened on the dust storage box 5;
[0030] The welding table 1 is provided with a fixed welding seat 12, the table legs 3 are provided with corrosion-resistant and anti-slip pads 31, and the dust extraction plate 62 is provided with a protective net 63. When not in use, the stainless steel protective net 63 prevents insects and rodents from entering.
[0031] The cab frame body 11 is a finished frame of the cab of the excavator, which is a prior art.
[0032] The dust extraction pump 41 is provided with a connecting pipe 42, which is connected to the inner cavity of the dust storage box 5. The connecting pipe 42 is not higher than the dust guide filter plate 51. The dust guide filter plate 51 is tilted as a whole and has an angle of twenty-three degrees with the horizontal plane. The dust guide filter plate 51 is not higher than the dust conveying main pipe 6. The filter element of the dust guide filter plate 51 is made of non-woven fabric. The inclined dust guide filter plate 51 not only blocks the dust particles from entering the dust extraction pump 41, but also ensures the dust extraction effect. At the same time, it realizes the tilted guidance of the blocked dust particles to concentrate them at the cleaning opening 52, which is convenient for later cleaning.
[0033] The clamping cylinder 2 and the clamping plate 21 form a group, which are two symmetrically arranged groups in total. The clamping plate 21 is in squeeze contact with the outer side wall of the cab frame body 11. A damping pad made of silicone rubber is preset on the clamping plate 21 to further realize the damping stable electronically controlled clamping of the cab frame body 11.
[0034] The inner cavity of the connecting sleeve 61 is connected to the inner cavity of the dust conveying main pipe 6 and the dust extraction plate 62 respectively. The dust extraction plate 62 is inclined at 35 degrees toward the cab frame body 11, further ensuring the inclined extraction of dust particles generated by welding.
[0035] The threaded pin 71 passes through the box baffle 7 and is threadedly connected to the dust storage box 5. The box baffle 7 is rotatably arranged with the dust storage box 5 through the rotating shaft 53, so that the box baffle 7 can be rotated to open, which is convenient for cleaning dust particles later.
[0036] The box baffle 7 is not smaller than the cleaning opening 52 to prevent dust particles from leaking out.
[0037] The welding seat 12 and the dust conveying main pipe 6 form a group, and there are four symmetrically arranged groups in total. The dust conveying main pipe 6 is a bent structure as a whole and vertically passes through the welding seat 12, which can effectively remove dust particles from all four sides.
[0038] There are four table legs 3 symmetrically arranged, and the corrosion-resistant and anti-slip pads 31 are arranged on the lower end surfaces of the table legs 3. The corrosion-resistant and anti-slip pads 31 are made of NBR nitrile rubber and have excellent corrosion resistance and anti-slip properties, which improve the overall anti-slip properties of the welding platform 1 during the welding process and the corrosion resistance of the bottom of the table legs 3.
[0039] Working method: Place the bottom metal steel frame original part on the welding table 1, then start the clamping cylinder 2 and stably clamp it through the clamping plate 21, then match the upper metal steel original part to the position of the bottom metal steel frame original part, and hold the handheld welding gun to weld it, and finally it will be welded into the frame structure of the excavator cab (this is the existing technology).
[0040] Dust particles will be generated during the welding process. By starting the dust extraction pump 41, the dust particles can be effectively extracted from all four sides through the four dust extraction plates 62 on the top. The extracted dust particles can be quickly transported through the dust conveying main pipe 6 and stored in the dust storage box 5, avoiding dust particles flying in the welding environment and causing pollution to the welding environment, thereby improving the dust and pollution resistance of the cab frame body 11 during the welding process as a whole.
[0041] Furthermore, the threaded pin 71 is rotated counterclockwise and removed, and then the box baffle 7 is rotated open, and the dust particles stored in the dust storage box 5 can be conveniently cleaned through the cleaning opening 52 .
[0042] In addition, the vertical portion of the dust conveying main pipe 6 is passed through the preset through-hole on the fixed welding seat 12 , and then the dust conveying main pipe 6 and the fixed welding seat 12 are firmly and fully welded to each other, further improving the overall welding support stability of the dust conveying main pipe 6 .
[0043] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
