[0028] [First embodiment]

[0029] As Figures 1-4As shown in the first embodiment of the utility model provides a kind of steel beam welding mechanical arm, as Figure 1 As shown, including mechanical arm main body 1, the extension end of mechanical arm main body 1 is provided with welding head 4, the mechanical arm generally has multiple degrees of freedom, can be moved flexibly in three-dimensional space by preset program and control system, to ensure accurate welding, automatically complete the welding task of steel beam.

[0030] The improvement of the embodiment compared with prior art is that the outer periphery of the welding head 4 is provided with a protective device 2, which is connected to the mechanical arm main body 1 in a detachable manner through a detachable device 3. By setting the protective device, the sparks generated during welding can be blocked by the protective cloth cover, preventing the flying sparks from causing damage to the operator and the mechanical arm, and reducing the safety hazards during use. At the same time, by setting the detachable device, the protective device can be easily detached and replaced for maintenance, which not only reduces the possibility of affecting the protection quality due to the burning gap on the surface of the protective device caused by the blocking of too many sparks, but also reduces the possibility of affecting the normal use of the protective device due to the accumulation of too many flying debris.

[0031] As Figure 3 shown, the protective device 2 in the embodiment includes a groove ring block 21, a protective cloth 22, and a limiting ring block 23. The groove ring block 21 is connected to the mechanical arm main body 1 in a detachable manner, the limiting ring block 23 is arranged on the outer periphery of the welding head 4 and away from the side of the groove ring block 21, and the two ends of the protective cloth 22 are fixedly connected to the groove ring block 21 and the limiting ring block 23, respectively. A limiting mechanism 25 is arranged on the outer side of the limiting ring block 23 and the groove ring block 21. As a further preferred embodiment, a plurality of first elastic members 24 are arranged between the groove ring block 21 and the limiting ring block 23, and the first elastic members 24 are arranged on the outer side of the protective cloth 22 and evenly spaced. By setting the protective device, the protective cloth can be installed on one side of the mechanical arm main body through the groove ring block and the limiting ring block, and covered on the outer periphery of the welding head. During welding, after the welding head contacts the steel beam, the side of the limiting ring block will abut on the surface of the steel beam under the reset support of the first elastic member, so that the protective cloth can cover the outer periphery of the welding head. In this way, the sparks generated during welding will be blocked by the protective cloth, preventing the flying sparks from causing damage to the operator and the mechanical arm, and reducing the safety hazards during use. When not in use or when the welding head needs to be replaced and maintained, the limiting ring block can be pressed and moved towards the side of the groove ring block, so that the protective cloth is folded and contracted, and the first elastic members 24 are contracted. Finally, the limiting mechanism is used to fix it, which facilitates the maintenance and replacement of the welding head. As a preferred embodiment, the first elastic member 24 can be a common elastic member such as a spring in the mechanical field.

[0032] As Figure 3As shown, the limiting ring block 23 is rotatably installed with a plurality of balls 26 away from one side of the groove ring block 21, and the plurality of balls 26 are evenly arranged at equal distances. By arranging the balls, the friction between the limiting ring block and the steel beam can be reduced, wear between the limiting ring block and the steel beam can be avoided, and the service life can be improved.

[0033] As shown, Figure 3 The limiting mechanism 25 in the embodiment includes a round rod 251 fixedly connected to the outer side of the limiting ring block 23, and an elastic limiting rod 252 rotatably connected to the outer side of the groove ring block 21. The elastic limiting rod 252 can be sleeved on the outer periphery of the round rod 251. By arranging the limiting mechanism, when the limiting ring block 23 is pressed and pushed to move to one side of the groove ring block 21, the protective cloth 22 is folded and shrunk, and the first elastic member is also shrunk. Then, the elastic limiting rod can be rotated to a certain angle, and one end of the inner wall of the elastic limiting rod is sleeved on the outer periphery of the round rod. Thus, the shrunk protective cloth can be limited and fixed, which is convenient for storage and maintenance and replacement of the welding joint. As a preferred, the inner wall of the elastic limiting rod 252 is fixedly installed with a rubber anti-slip block 253. By arranging the anti-slip block, the contact friction of the inner wall of the one end of the elastic limiting rod can be increased, so that the elastic limiting rod is more stable when it is sleeved on the outer surface of the round rod.

[0034] As shown, Figure 2 and Figure 4 The detachable device 3 in the embodiment includes a groove clamping block 33 fixedly installed with the groove ring block 21. The mechanical arm body 1 is provided with a clamping groove 31, and the inner wall of the clamping groove 31 is provided with a clamping hole 32. A clamping rod 35 is located in the interior of the groove clamping block 33 and is slidably connected thereto. The groove clamping block 33 and the clamping rod 35 are respectively inserted into the inner wall of the clamping groove 31 and the clamping hole 32. A second elastic member 34 is arranged between the clamping rod 35 and the groove clamping block 33. By arranging the detachable device 3, when it is necessary to replace the protective cloth, the clamping rod can be manually pulled out to a certain position in the inner wall of the groove clamping block, the second elastic member is stretched, and then the clamping rod is pulled out from the clamping hole. Then, the groove clamping block can be pulled out from the clamping groove, so that the protective cloth can be detached from one side of the mechanical arm body, which is convenient for replacement of the protective cloth.

[0035] As a further preferred, the outer side of the clamping rod 35 is fixedly installed with a pull block 36 with a circular arc cross section. By arranging the pull block, the contact area of one side of the clamping rod can be increased, so that the one side of the clamping rod can be easily gripped and pulled manually. The detachable device 3 in the embodiment further includes a telescopic rod 37, the two ends of which are fixedly connected with the clamping rod 35 and the groove clamping block 33, respectively. The second elastic member 34 is sleeved on the outer periphery of the telescopic rod 37. By arranging the telescopic rod 37, the inner wall of the second elastic member 34 can be supported and reinforced, so that it is not easy to be damaged during use.

[0036] The working process of the embodiment is as follows:

[0037] The protective cloth 22 is installed on one side of the mechanical arm body 1 through the groove ring block 21, the limiting ring block 23 and the first elastic members 24, and covers the outer periphery of the welding head 4, so that the protective cloth 22 can cover the outer surface of the welding head 4. When the welding head 4 contacts the steel beam, the limiting ring block 23 on one side is abutted on the surface of the steel beam under the reset support of the first elastic members 24, so that the sparks generated in the welding process are blocked by the protective cloth 22, and the operator is prevented from being scalded by the flying sparks, and the safety hidden danger in use is reduced.

[0038] When not in use or when the welding head 4 needs to be maintained, the limiting ring block 23 can be pressed and pushed to move to one side of the groove ring block 21, so that the protective cloth 22 is folded and shrunk, and the first elastic members 24 are stretched. Then, the elastic limiting rod 252 can be rotated to a certain angle, and the inner wall of one end of the elastic limiting rod 252 is sleeved on the outer surface of the circular rod 251, so that the shrunk protective cloth 22 can be limited and fixed, and the welding head 4 is convenient to maintain and replace.

[0039] When the protective cloth 22 needs to be replaced, the clamping rod 35 can be manually pulled out to a certain position in the inner wall of the groove clamping block 33 to stretch the second elastic member 34, and then pulled out from the clamping hole 32. Then, the groove ring block 21 is pulled away from the one end of the mechanical arm body 1, so that the groove clamping block 33 can be pulled out from the clamping groove 31. Therefore, the protective cloth 22 can be detached from one side of the mechanical arm body 1, and the replacement is convenient.
