Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of welding, and specifically, to a dust suction device for a robot welding torch. Background Art
[0002] In industrial production, metal materials are widely used in actual production due to their firm and reliable properties. Electric welding, as a basic processing technology for hot processing of metal materials, is indispensable in the actual application of metal materials. However, during the production process of electric welding, the heated metal and the welding torch generate gases harmful to the human body and the environment under the action of high temperature. Working in a harmful gas environment for a long time causes great harm to the physical and mental health of operators, and at the same time causes relatively large environmental pollution, which is not conducive to environmental protection. With the improvement of people's environmental protection awareness, it has become an urgent problem to be solved during the welding process to select certain effective ways to improve the welding environment and reduce the damage of welding-generated dust to workers and environmental pollution.
[0003] For example, a welding workstation with good sealing effect is built, and the welding work is completed inside the welding workstation. The polluting fumes generated during the welding process are collected uniformly. However, the cost of the welding workshop is high, and the polluting gases generated during the welding process still have a certain impact on the operator. Secondly, during the welding process of larger workpieces, a larger welding workstation is required, and the manufacturing cost of the welding workstation is relatively high, and the difficulty in hoisting and transporting the workpiece is relatively large. In order to protect the health of operators, with the development of technology, the robot welding torch has emerged. Although the robot welding torch avoids physical and mental damage to the operator.
[0004] When using a robot welding torch for welding operations, the polluted gases usually adopt the top suction or side suction collection method to collect the fume dust generated during the operation of the robot. The fume dust can be collected in time within the diffusion range of the fume dust. At the same time, arc shielding curtains are installed around the suction hood, which can not only prevent the escape of welding fumes but also reduce the harm of strong light to the eyes. This solution has high collection efficiency and high collection cost, which is not conducive to popularization and application.
[0005] Therefore, there is an urgent need for a dust suction device that can be adapted to a variety of robot welding torches now. Summary of the Utility Model

[0026] The following will combine with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.
[0027] As shown Figures 1-4 in the figure, a dust suction device for a robotic welding torch includes a telescopic pipe 1. One end of the telescopic pipe 1 is connected to a dust suction head 2, and the other end of the telescopic pipe 1 is connected to a multi-channel connection body 3. A gas channel interface 31 and a welding torch connection port 32 are provided on the multi-channel connection body 3, and both the gas channel interface 31 and the welding torch connection port 32 are in communication with the telescopic pipe 1. The multi-channel connection body 3 is provided with a welding torch connection port 32 that can accommodate the welding torch to pass through, and is also connected to the telescopic pipe 1 to allow the harmful fumes inside the telescopic pipe 1 to enter the fume collection and treatment device through the gas channel interface 31. The welding torch is sleeved inside the telescopic pipe 1, and the dust suction head 2 is sleeved with the welding torch. During the welding process, the dust suction head 2 has a stronger ability to absorb fumes, avoiding the situation where the fumes generated during welding cannot be effectively sucked or affecting the welding operation.
[0028] It further includes at least two sealing clips 4. The sealing clips 4 are arranged at the welding torch connection port 32, and a welding torch extension pipe 51 is arranged inside the sealing clips 4. The welding torch extension pipe 51 extends out from the dust suction head 2. In order to improve the sealing degree between the welding torch extension pipe 51 and the multi-channel connection body 3, the welding torch extension pipe 51 and the multi-channel connection body 3 are sealed by the sealing clips 4. The welding torch extension pipe 51 extends out from the dust suction head 2, so the dust suction head 2 will not affect the welding work of the welding torch extension pipe 51. At the same time, the dust suction head 2 can better absorb the harmful fumes generated during welding. The welding torch extension pipe 51 is connected to the welding torch 5, and the welding torch extension pipe 51 is a part used to extend the welding torch 5 for convenient welding operation.
[0029] As shown Figures 1-4 in the figure, the sealing clip 4 includes a top piece 41, a wedge block 42, a guide post 43 and a mounting hole 44. The top piece 41 is arranged on one side of the wedge block 42, the guide post 43 is arranged on the other side of the wedge block 42, and the mounting hole 44 passes through the top piece 41, the wedge block 42 and the guide post 43 in sequence.
[0030] A wedge-shaped mounting ring 33 is arranged at the end of the welding torch connection port 32 away from the telescopic pipe 1, and the wedge block 42 is arranged in cooperation with the wedge-shaped mounting ring 33. The guide post 43 is arranged inside the welding torch connection port 32, and the welding torch connection port 32 plays a guiding role. When the sealing clip 4 is further inserted into the inside of the welding torch connection port 32, the wedge-shaped mounting ring 33 acts on the wedge block 42 to achieve the effect of clamping and sealing. At the same time, the mounting hole 44 clamps the welding torch extension pipe 51, and the sealing effect is better. In order to further improve the sealing effect, sealing rings or sealing grease can also be provided between the wedge-shaped mounting ring 33 and the wedge block 42, and between the welding torch extension pipe 51 and the mounting hole 44 to improve the sealing effect.
[0031] As shown Figure 1 、 2As shown in FIGS. 3 and 4, the dust suction head 2 includes a dust suction cylinder 21 and a plurality of air inlet holes 22. One end of the dust suction cylinder 21 is communicated with the telescopic pipe 1, and the plurality of air inlet holes 22 are uniformly arranged on the dust suction cylinder 21. In order to improve the dust suction effect of the dust suction head 2, the dust suction head 2 includes a dust suction cylinder 21 and a plurality of air inlet holes 22. Harmful smoke and dust can not only enter the telescopic pipe 1 between the dust suction head 2 and the welding torch extension pipe 51, but also enter the telescopic pipe 1 through the air inlet holes 22. The smoke and dust can enter the dust suction head 2 through the air inlet holes 22 and the dust suction cylinder 21. The smoke and dust entering through the air inlet holes 22 can also prevent the smoke and dust entering from the dust suction cylinder 21 from flowing out of the dust suction cylinder 21, increasing the entering space and enhancing the ability to absorb smoke and dust.
[0032] The inner diameter of the end of the dust suction cylinder 21 communicated with the telescopic pipe 1 is larger than the end of the dust suction cylinder 21 far from the telescopic pipe. The dust suction cylinder 21 is conical to prevent the smoke and dust sucked into the dust suction cylinder 21 from flowing out of the dust suction cylinder.
[0033] The distance between the end of the welding torch extension pipe 51 far from the welding torch inlet 32 and the end of the dust suction cylinder 21 far from the telescopic pipe 1 is 25-30 mm. The welding torch extension pipe 51 needs to perform welding work, and the dust suction cylinder 21 needs to suck more smoke and dust. The closer the dust suction cylinder 21 is to the end of the welding torch extension pipe 51, the stronger the ability to suck smoke and dust. The dust suction cylinder 21 will affect the work of the welding torch extension pipe 51. According to actual production experience, when the distance between the end of the welding torch extension pipe 51 far from the welding torch inlet 32 and the end of the dust suction cylinder 21 far from the telescopic pipe 1 is within the range of 25-30 mm, the effect is better, preferably 28 mm.
[0034] A connecting sleeve 35 is arranged between the telescopic pipe 1 and the multi-channel connection body 3. The connecting sleeve 35 is used to connect the telescopic pipe 1 and the multi-channel connection body 3, which is convenient for disassembly and maintenance, and for cleaning the smoke and dust inside the telescopic pipe 1 and the multi-channel connection body 3 to prevent blockage from affecting the dust suction effect.
[0035] The multi-channel connection body 3 is connected with a smoke and dust circulation pipe 34, and the smoke and dust circulation pipe 34 is communicated with the gas channel interface 31 and the welding torch inlet 32. The smoke and dust conversion pipe 34 prevents the smoke and dust from returning along the telescopic pipe 1 to the dust suction cylinder 21 again, increases the amount of smoke and dust entering the gas channel interface 31, and enhances the dust suction effect.
[0036] The gas channel interface 31 and the smoke and dust circulation pipe 34 are integrally formed or connected by threads. Integral forming has a better sealing effect, and threaded connection is convenient for disassembly and replacement. The connection method of the gas channel interface 31 and the smoke and dust circulation pipe 34 needs to be selected according to the actual use scenario and working duration.
[0037] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
