Description

Technical Field

[0001] The utility model belongs to the technical field of welding robots, and in particular relates to a device for preventing welding slag from splashing for a welding robot. Background Art

[0002] Welding robots are industrial robots that perform welding. They are used to attach welding tongs or welding guns to the end flange of industrial robots so that they can perform welding. At present, welding robots have been widely used in the automotive manufacturing industry, such as welding of automobile chassis, seat frames, guide rails, mufflers, and torque converters, especially in the welding production of automobile chassis.

[0003] Since the welding robot is modified based on the industrial robot, its rotating mechanism is still the structure of the industrial robot, including the base and the rotating turntable on the base. Since the welding robot will generate welding slag splashing during operation, this traditional industrial robot rotating structure causes the welding slag to easily enter the gap between the base and the turntable, causing rotation jamming, affecting the accuracy of the welding robot, and even causing the rotating structure to fail to work normally. In summary, there is an urgent need for a device to prevent welding slag splashing for a welding robot. Utility Model Content

[0018] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the utility model.

[0019] like Figure 1 , Figure 2 As shown, the welding slag splash prevention device for a welding robot of the utility model comprises a base 1, a turntable 2 arranged above the base 1, a welding robot 3 arranged above the turntable 2, and a welding slag retaining ring 4 sleeved on the outer side of the turntable 2, wherein the base 1 comprises a fixed plate 11, a fixed sleeve 12 connected to the top of the fixed plate 11, the fixed sleeve 12 is at least partially arranged in the welding slag retaining ring 4, a driving mechanism connected to the turntable 2 is arranged inside the fixed sleeve 12, a baffle 5 is arranged on the outside, and an air nozzle 6 connected to the fixed sleeve 12 is arranged directly above the baffle 5, one end of the welding slag retaining ring 4 is fixedly connected to the outer side of the turntable 2, and a circle of brushes 7 is arranged on the inner side of the other end, the brush 7 abuts against the outer side of the fixed sleeve 12, the vertical position of the brush 7 matches the vertical position of the baffle 5, and the turntable 2 is hinged above the fixed sleeve 12.

[0020] Furthermore, in the welding slag splash prevention device for a welding robot of the utility model, the vertical distance between the bottom end of the welding slag retaining ring 4 and the top end of the fixed plate 11 is a set value. More specifically, the set value should be greater than the welding slag diameter. This arrangement facilitates the discharge of welding slag from between the welding slag retaining ring 4 and the fixed plate 11, and prevents the welding slag from being stuck between the bottom end of the welding slag retaining ring 4 and the top end of the fixed plate 11, causing rotation jamming.

[0021] Furthermore, in the welding slag splash prevention device for a welding robot of the utility model, there is a gap between the bottom end of the turntable 2 and the top end of the fixed sleeve 12, and the turntable 2 can be rotated relative to the fixed sleeve 12 through a driving mechanism. During the rotation of the turntable 2, the gap between the turntable 2 and the fixed sleeve 12 is always located inside the welding slag retaining ring 4, so that the splashing welding slag is not easy to enter.

[0022] As a specific implementation, in the welding slag splash prevention device for a welding robot of the utility model, the fixing plate 11 is fixed to the construction platform by fasteners. Of course, the fixing plate 11 can also be directly welded and fixed to the construction platform as long as the overall fixed support effect of the device is met.

[0023] As a specific implementation, in the welding slag splash prevention device for a welding robot of the present invention, the driving mechanism is a motor, which provides power to drive the turntable 2 to rotate to meet the changes in the welding position of the welding robot 3.

[0024] As a specific implementation, in the welding slag anti-splash device for a welding robot of the utility model, the air outlet of the air nozzle 6 is located on one side of the baffle 55, and air is blown downward through the air outlet of the air nozzle 6 to prevent the welding slag from moving upward, so that the welding slag hanging on the brush 7 falls off downward, and at the same time, the lower end of the base 1 is purged to prevent the welding slag from gathering, thereby causing a large amount of welding slag to be stuck between the bottom end of the welding slag baffle ring 4 and the top end of the fixed plate 11, causing rotation jamming.

[0025] The working principle of the welding slag splash prevention device for a welding robot of the utility model is as follows: first, the turntable 2 is rotated by a driving mechanism to meet the change of the welding position of the welding robot, and the welding slag retaining ring 4 is driven to rotate during the rotation of the turntable 2. At this time, the brush 7 is closed between the welding slag retaining ring 4 and the fixed sleeve 12. During the rotation of the welding slag retaining ring 4, the brush 7 is driven to rotate. During the rotation, the brush 7 continuously hits the retaining plate 5, so that part of the welding slag splashed at the bottom of the brush 7 is hung off by the retaining plate 55, and at the same time, under the strong blowing of the air nozzle 6, part of the welding slag splashed at the bottom of the brush 7 falls off downward.

[0026] In summary, compared with the prior art, the welding slag splash prevention device for a welding robot of the present invention has the following advantages and beneficial effects:

[0027] The device has a simple structure and is easy to assemble and disassemble. A slag retaining ring 4 is used to prevent splashing slag from entering the gap between the turntable 2 and the fixed sleeve 12. A brush 7 and a strong blower of an air nozzle 6 are used to perform secondary blocking of the slag. This effectively avoids the problem that the welding robot 3 is stuck in rotation due to accumulation of slag and clogging of the rotating mechanism, which in turn affects the welding accuracy, and greatly improves the safety of the welding process.
