Description

Technical Field

[0001] The invention relates to a servo motor end cover welding device, in particular to a servo motor end cover welding device, belonging to the technical field of welding equipment. Background Art

[0002] Welding equipment is the equipment needed to realize the welding process. Welding equipment includes welding machines, welding process equipment and welding auxiliary equipment. Welding equipment is required for welding in different workpiece processing, such as sheet metal processing or servo motor end covers. However, traditional welding equipment will produce a large amount of harmful gases when working, that is, electric welding aerosols, which can cause respiratory mucosal irritation, inflammation, welder pneumoconiosis and poisoning. In this environment, it is not conducive to the normal and healthy work of the staff, and the work efficiency will also be reduced;

[0003] The announcement number is CN213497109U, which discloses "a welding device with welding fume removal function for hardware production, including a servo motor, an output end of the servo motor is fixedly connected to an output shaft, an end of the output shaft away from the servo motor is fixedly connected to a connecting ring, a fan blade is fixedly connected to the outer surface of the connecting ring, a motor seat is fixedly connected to one side of the servo motor, a motor box is fixedly connected to the upper surface of the motor seat, and a fixed frame is fixedly connected to the outer surface of the motor box. When welding the workpiece, turn on the servo motor, let the output shaft start to rotate, thereby driving the connecting ring to rotate, and then use the fan blade to absorb and collect the smoke generated in the welding from the through hole to prevent the workers from inhaling a large amount of smoke and causing damage to their own health.

[0004] The above patent has the following shortcomings: in order to improve the processing environment, a dust suction device is installed on the outside of the welding equipment, but the dust suction device cannot be used as needed. For example, the suction nozzle is far away from the welding gun, and the smoke generated by welding is more easily affected by air flow during the diffusion process, resulting in part of the smoke being unable to be effectively sucked into the suction nozzle, thereby reducing the smoke collection efficiency. Part of the smoke will stay near the worker's breathing zone for a longer time, increasing the risk of workers inhaling harmful smoke, which may lead to occupational diseases such as welder's pneumoconiosis, chronic bronchitis, etc. Therefore, the dust suction device cannot meet the use requirements.

[0021] The present invention has at least the following beneficial effects:

[0022] 1.

[0024] 2. For the servo motor end cover welding equipment, as the welding gun head approaches the welding object, the amount of smoke generated during welding usually increases. At this time, the transmission of the rack and the gear is coordinated with the rotating shaft to drive the worm to rotate, and the rotation of the worm and the meshing of the worm wheel drive the rotating seat to rotate, thereby driving the five baffles to rotate outward synchronously to open the through hole.

On the contrary, when the welding gun head is away from the workpiece, the transmission structure is used to restore and adjust the five baffles to achieve the size adjustment of the through hole, so that it can be used according to needs, thereby improving the flexibility and adaptability of welding operations.

[0025] 3. The servo motor end cover welding equipment can filter the smoke during welding by installing a filter structure in the filter tube, and intercept the particulate matter in the smoke inside the filter tube to achieve a purification effect, thereby preventing workers from inhaling these harmful substances for a long time, which may cause damage to the human respiratory system, nervous system, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0037] like Figure 1 and Figure 2 As shown, the servo motor end cover welding equipment provided in this embodiment includes a welding gun head 3 installed on a mounting bracket 1 and a bottom plate 2 for welding the servo motor end cover, the top of the welding gun head 3 is fixedly connected with a gun barrel 31, and the top of the gun barrel 31 is fixedly connected with a connecting pipe 4 connected with the welding equipment, and a telescopic electric cylinder 5 and a dust collection device 6 are arranged on the mounting bracket 1 and the bottom plate 2; the dust collection device 6 includes a dust collection box 601 fixedly installed on the upper surface of the mounting bracket 1, a telescopic dust collection pipe 602 arranged between the mounting bracket 1 and the bottom plate 2, a connecting pipe 603 fixedly connected to the top of the telescopic dust collection pipe 602, and a filter pipe 604 fixedly connected between the connecting pipe 603 and the dust collection box 601. The telescopic dust collection pipe 602 can flexibly adjust the length and angle according to the welding position to ensure that the dust collection port is always close to the smoke generation area to improve the dust collection efficiency.

[0038] Specifically, the telescopic dust suction tube 602 includes a first telescopic tube 6021 and a second telescopic tube 6022 that are telescopically connected, and a suction nozzle 6023 that is fixedly connected to the bottom end of the second telescopic tube 6022 and is used to absorb smoke and dust; the suction nozzle 6023 is located on one side of the welding gun head 3, the first telescopic tube 6021 is fixedly passed through the inside of the mounting bracket 1, the second telescopic tube 6022 is fixedly passed through the inside of the bottom plate 2, and the top end of the second telescopic tube 6022 extends to the inside of the first telescopic tube 6021. The dust suction box 601 is composed of a box body and a dust suction fan, which is installed on a side of the box body away from the filter tube 604, and can form a negative pressure in the box body, so that dust suction is performed through the suction nozzle 6023.

[0039] In order to ensure that the second telescopic tube 6022 and the first telescopic tube 6021 are stably extended and retracted, in this embodiment, Figure 3 As shown, a limiting structure 606 is provided on the outer surface of the top of the second telescopic tube 6022, and the limiting structure 606 includes a connecting rod 6061 fixedly mounted on the outer wall of the top of the second telescopic tube 6022 and a roller 6062 rotatably mounted on the other end of the connecting rod 6061. A limiting slide 6063 adapted to the roller 6062 is provided inside the first telescopic tube 6021, and the roller 6062 and the limiting slide 6063 are rollingly matched. Through the rolling cooperation between the roller 6062 and the limiting slide 6063, the second telescopic tube 6022 and the first telescopic tube 6021 are ensured to be stably extended and retracted, and the stability of the suction nozzle 6023 when moving is improved. At the same time, the second telescopic tube 6022 and the first telescopic tube 6021 can be limited so that they will not be disconnected. There are two limiting structures 606, and the two limiting structures 606 are symmetrically arranged.

[0040] In order to improve the smoke collection effect, in this embodiment, if Figure 7 and Figure 8 As shown, a filter structure 605 for filtering smoke is provided in the filter tube 604. The filter structure 605 includes a filter shell 6051 detachably mounted inside the filter tube 604, a cover plate 6052 mounted on the outside of the filter shell 6051 by bolts, a filter screen 6053 detachably mounted inside the filter shell 6051, and an activated carbon adsorption plate 6054. By installing the filter structure 605 in the filter tube 604, the smoke during welding can be filtered, and the particles in the smoke can be trapped inside the filter tube 604, achieving a purification effect, and preventing the staff from inhaling these harmful substances for a long time, which may cause damage to the respiratory system, nervous system, etc. of the human body.

[0041] The filter housing 6051 and the cover plate 6052 are provided with a plurality of ventilation holes 6056. The filter housing 6051 is hollow, and the inner side of the filter housing 6051 and the outer wall of the filter screen 6053 are provided with matching threads 6055, so as to facilitate the later maintenance of the filter structure 605. The outside of the filter tube 604 is provided with a maintenance housing by bolts.

[0042] In this embodiment, if Figure 1 and Figure 2 As shown, the telescopic electric cylinder 5 is mounted on the upper surface of the mounting bracket 1 by bolts, and its output end passes through the interior of the mounting bracket 1 and is connected and fixed to the upper surface of the bottom plate 2, the welding gun head 3 is fixedly passed through the interior of the bottom plate 2, and the gun barrel 31 passes through the interior of the mounting bracket 1. The mounting bracket 1 is Z-shaped in shape, and a mounting hole for installation is opened inside it.

[0043] In order to achieve dynamic coordination between the welding gun and the dust suction force, in this embodiment, Figure 1 , Figure 4-Figure 6 As shown, a flow control mechanism 7 is provided on the first telescopic tube 6021 and the base plate 2, and the flow control mechanism 7 includes a valve housing 701 fixedly installed inside the first telescopic tube 6021, a rotating seat 703 rotatably installed inside the valve housing 701, a baffle plate 704 rotatably installed outside the rotating seat 703, a connecting rod 705 rotatably connected between the rotating seat 703 and the baffle plate 704, and a transmission structure 707 installed on the first telescopic tube 6021 and the base plate 2 for driving the rotating seat 703; the valve housing 701 is located at the top end of the second telescopic tube 6022. Among them, the transmission structure 707 includes a rack 7071 fixedly installed on the upper surface of the base plate 2, a rotating shaft 7072 rotatably installed inside the first telescopic tube 6021, a gear 7073 fixedly installed on one end of the rotating shaft 7072 and meshing with the rack 7071, a worm wheel 7075 fixedly installed on the outer surface of the rotating seat 703, and a worm 7074 fixedly installed on the other end of the rotating shaft 7072 and meshing with the worm wheel 7075.

[0044] In this embodiment, a through hole 702 that is connected up and down is provided inside the valve housing 701 and the rotating seat 703. The baffle plate 704 has an outer shape of one-fifth of a circle, and an extension groove 7041 for accommodating the connecting rod 705 is provided inside the baffle plate 704. An opening 7042 of one-fifth of a circle is provided on one side of the baffle plate 704 close to the through hole 702.

[0045] Specifically, the number of shielding plates 704 and connecting rods 705 are both five, and the five shielding plates 704 are equidistantly distributed around the rotating seat 703, wherein the equidistant distribution of the five openings 7042 forms a perforation 706, so that the telescopic dust suction tube 602 can be connected, preventing the telescopic dust suction tube 602 from closing and causing damage to the dust suction box 601. The interior of the valve housing 701 is hollow, and an inspection cover 7011 is installed on the upper surface of the valve housing 701 through multiple groups of bolts, and a limit seat 7076 for limiting the rotating shaft 7072 is welded on the inner wall of the valve housing 701 to ensure the stable rotation of the rotating shaft 7072 and improve the transmission stability.

[0046] It is understandable that as the welding gun head 3 approaches the welding object, the amount of smoke generated during the welding process will usually increase. At this time, the transmission of the rack 7071 and the gear 7073 is coordinated with the rotating shaft 7072 to drive the worm 7074 to rotate. The rotation of the worm 7074 engages with the worm wheel 7075 to drive the rotating seat 703 to rotate, thereby driving the five baffles 704 to rotate outward synchronously to open the through hole 702. At this time, the dust suction through hole 702 becomes wider, and the dust suction box 601 will increase the dust suction force to ensure that more smoke is sucked away in time and reduce the residence time and diffusion range of the smoke in the air. On the contrary, when the welding gun head 3 is away from the workpiece, the transmission structure 707 is used to restore and adjust the five baffles 704 to achieve the size adjustment of the through hole 702, so that it can be used according to needs, thereby improving the flexibility and adaptability of the welding operation.

[0047] The rotating shaft 7072 is connected to the limit seat 7076 and the valve housing 701 by bearings. The outer surface of the first telescopic tube 6021 is sleeved with a limit ring 60211 for limiting the rack 7071, which can limit the rack 7071 and cooperate with the roller 6062 and the limit slide groove 6063 to facilitate the transmission structure 707 to adjust and steer the five baffles 704.

[0048] It should be noted that the length of the limiting slide groove 6063 is adapted to the moving length of the rack 7071, so as to better operate the five shielding plates 704 to open and close the through hole 702. When the rack 7071 abuts against the limiting collar 60211, the five shielding plates 704 are closed, and when the roller 6062 abuts against the inner bottom wall of the limiting slide groove 6063, the five shielding plates 704 are fully unfolded.

[0049] like Figure 1-Figure 8 As shown, the principle of the servo motor end cover welding equipment provided in this embodiment is as follows:

[0050] When in use, the welding gun head 3 is installed and fixed using the mounting bracket 1, and then the welding gun head 3 is connected to the welding equipment through the connecting pipe 4 and the barrel 31 to achieve welding of the servo motor end cover, and the welding gun head 3 is driven to move by the telescopic electric cylinder 5 so that it can perform welding work better, and at the same time, the suction nozzle 6023 moves close to the workpiece accordingly. As the welding gun head 3 approaches the welding object, the amount of smoke generated during the welding process usually increases. At this time, the transmission cooperation between the rack 7071 and the gear 7073 uses the rotating shaft 7072 to drive the worm 7074 to rotate, and the worm 7074 rotates The engagement with the worm gear 7075 drives the rotating seat 703 to rotate, thereby driving the five baffles 704 to rotate outward synchronously to open the through hole 702. At this time, the dust suction through hole 702 becomes wider, and the dust suction box 601 will increase the dust suction force, which can ensure that more smoke and dust are sucked away in time and reduce the residence time and diffusion range of smoke and dust in the air. On the contrary, when the welding gun head 3 is away from the workpiece, the transmission structure 707 is used to restore and adjust the five baffles 704 to achieve the size adjustment of the through hole 702, so that it can be used according to needs, thereby improving the flexibility and adaptability of welding operations.

[0051] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0052] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.
