Description

Technical Field

[0001] This invention relates to the field of fixture technology, specifically to a fixture device for welding processing of industrial robots. Background Technology

[0002] An industrial robot is a multi-jointed manipulator or a machine device with multiple degrees of freedom designed for industrial applications. In industrial production and processing, it replaces humans in performing certain monotonous, frequent, and repetitive long-term tasks through automatic control. It can be commanded by humans or run according to pre-programmed procedures. Modern industrial robots can also make autonomous decisions and take actions based on principles and guidelines specified by artificial intelligence technology. A fixture is a device used in mechanical manufacturing to fix a workpiece in the correct position for construction or inspection. It is also called a clamp. In a broader sense, any device used to quickly, conveniently and safely install a workpiece in any step of the process can be called a fixture. When welding with an industrial robot, a fixture is usually used to fix the workpiece to be welded.

[0003] Existing fixtures often experience misfits when clamping workpieces of circular or other irregular shapes, leading to insufficient stability during clamping. This affects the positioning of industrial robots and consequently impacts welding results. Furthermore, during welding, the high temperatures and lack of cooling mechanisms in the fixture result in strong molten metal flow, potentially causing excessively wide welds and surface irregularities. To address this, a fixture device for welding processing of industrial robots is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a clamping device for welding processing of industrial robots. By driving the transmission shaft to rotate clockwise, two movable rings slide towards each other, bringing the two fixed clamps closer together to clamp the workpiece to be welded. This ensures the stability of the workpiece and facilitates welding. It also improves the stability of the workpiece during clamping. Furthermore, the slot design allows irregularly shaped workpieces to be stably clamped inside the anti-slip block, improving the applicability of the fixed clamp.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A fixture device for welding processing of industrial robots includes two support bases 1. A rotating base 103 is rotatably mounted on the inner wall of the top of each of the two support bases 1. A welding support plate 104 is fixedly mounted on the inner side of the two rotating bases 103. A cavity 107 is opened at the top of one of the support bases 1. A rotating component 2 for driving the welding support plate 104 to rotate is arranged in the cavity 107. An opening slot 105 is opened at the top of the welding support plate 104. Clamping components are symmetrically arranged on both sides of the opening slot 105. The clamping components include a movable frame 302 fixedly mounted at the bottom of the welding support plate 104. Two fixed clamps 106 are symmetrically arranged on the movable frame 302 on the same side. A cooling component 4 is also symmetrically arranged at the bottom of the welding support plate 104. The cooling component 4 includes a water tank 401 symmetrically fixedly mounted at the bottom of the welding support plate 104. The cooling component 4 is used to cool the two fixed clamps 106 on the same side. The rotating component 2 drives the workpiece to be welded on the fixed clamps 106 to rotate while driving the water tank 401 to flip.

[0006] Preferably, the movable frame has a movable groove on its side wall, and a drive shaft is rotatably installed in the movable groove. A second motor is fixedly installed on the side wall of the movable frame, and the output end of the second motor is fixedly connected to the central shaft of the drive shaft. Threaded strips are fixedly installed at both ends of the drive shaft, and movable rings are sleeved on the outer sides of both ends of the drive shaft. Threaded holes that match the threaded strips are opened in the movable rings. The movable rings are fixedly connected to the bottom ends of the fixed clamps. The fixed clamps are semi-circular, and anti-slip blocks are fixedly installed on the inner side of the fixed clamps.

[0007] With the above solution: In use, when the second motor is powered on, it drives the transmission shaft to rotate within the movable slot. At this time, the movable ring can rotate along the threaded strip on the outside of the transmission shaft through the threaded hole. When the second motor rotates clockwise, it drives the transmission shaft to rotate clockwise. At this time, the two movable rings slide towards each other, and the two fixed clamps can approach each other, which can clamp the workpiece to be welded, ensuring its stability and facilitating welding. When the second motor rotates counterclockwise, the two movable rings slide in opposite directions, and the two fixed clamps can separate, allowing the clamped workpiece to be released and facilitating the replacement of different workpieces to be processed.

[0008] Preferably, the anti-slip block is made of high-temperature resistant rubber material, and multiple slots are evenly provided on the inner side of the anti-slip block.

[0009] Through the above solution: the rubber material can increase the friction between the workpiece to be welded and the fixing clamp, which can improve the stability of the workpiece during the clamping process, and the slot design can stably clamp irregularly shaped workpieces to be welded inside the anti-slip block, thereby improving the applicability of the fixing clamp.

[0010] Preferably, the two threaded strips are symmetrically arranged about the middle position of the drive shaft, and the pitch of the threaded strips gradually decreases from both ends of the drive shaft towards the middle position.

[0011] The above solution ensures the movement accuracy of the drive shaft by using a smaller thread pitch. When the fixed clamp holds and fixes the workpiece to be welded, the moving ring moves to the position where the thread pitch is smaller, allowing the anti-slip block on the fixed clamp to fit more tightly with the workpiece to be welded, thus ensuring the clamping effect.

[0012] Preferably, a water pump is fixedly installed on the side wall at the bottom of the water storage tank. The inlet of the water pump extends into the water storage tank, and the outlet of the water pump is connected to a water injection pipe. A first condensing chamber and a second condensing chamber are provided inside the fixing clamp. A baffle is fixedly installed between the first condensing chamber and the second condensing chamber. The bottom ends of the first condensing chamber and the second condensing chamber are separated by the baffle, and the top ends of the first condensing chamber and the second condensing chamber are connected.

[0013] Through the above scheme: during use, the water pump can guide the coolant in the water storage tank into the water injection pipe, and further guide it into the second condensing chamber through the water injection pipe. From the top of the second condensing chamber, it flows into the first condensing chamber, filling the entire fixing clamp with coolant. This can cool the anti-slip block inside the fixing clamp and further cool the welded parts during the welding process. It can prevent the welded parts from becoming too hot during the welding process, thus increasing the fluidity of the molten metal. It can also prevent defects such as excessively wide welds, uneven surfaces, and undercut. In addition, the baffle increases the flow time of the coolant in the fixing clamp, ensuring the cooling effect.

[0014] Preferably, the bottom end of the second condensing chamber is connected to the water injection pipe, and the bottom end of the first condensing chamber is connected to a return water pipe, the bottom end of which extends into the water storage tank. The return water pipes and the water injection pipes on the two fixing clamps on the same side are respectively connected.

[0015] The above solution, through the cooperation of the water injection pipe and the water return pipe, enables the recycling of coolant, reduces water waste, and lowers processing costs.

[0016] Preferably, the water storage tank is filled with condensate, and V-shaped grooves are provided at both the upper and lower ends of the water storage tank, with the V-shaped grooves embedded in the water storage tank. A baffle block is integrally provided on the inner wall of the V-shaped groove, and the baffle block is cone-shaped.

[0017] Through the above scheme: as the water tank slowly rotates with the welded support plate, the coolant inside the water tank can flow continuously, and the V-shaped groove can cause the coolant to slosh significantly during the flow, which can make the temperature distribution of the coolant uniform and ensure the cooling effect. In addition, the V-shaped groove can increase the contact area between the water tank and the external environment, which can accelerate the natural cooling efficiency of the coolant in the water tank and further ensure the cooling effect. Furthermore, during the rotation of the water tank, the turbulence block can increase the mixing effect of the coolant and ensure the rapid cooling of the cooling water.

[0018] Preferably, the rotating assembly includes a first motor fixedly installed at the bottom of the cavity, a second pulley fixedly connected to the output end of the first motor, a first pulley rotatably installed on the side wall at the top of the cavity, the central axis of the first pulley being fixedly connected to the side wall of the rotating seat, and a transmission belt being sleeved on the outer sides of the first pulley and the second pulley.

[0019] With the above solution: when the first motor is powered on, the first motor can drive the second pulley to rotate through the first pulley and the transmission belt. At this time, the second pulley can drive the rotating seat to rotate at the top of the support seat, so that different positions of the welding support plate can be moved to the top of the support seat, which is convenient for welding different positions of the parts to be welded on the fixed clamp, thereby improving welding efficiency and reducing the welding difficulty of industrial robots.

[0020] Preferably, a heat sink is provided on the side wall of the cavity located at the first motor.

[0021] The above solution helps the heat sink dissipate heat from the first motor, ensuring its long-term safe use and extending its service life.

[0022] Preferably, a PLC controller is also fixedly installed on one of the support bases, and the PLC controller is electrically connected to the first motor, the second motor and the water pump.

[0023] The above solution allows for automatic control of the first motor, second motor, and water pump via a PLC controller, reducing manual operation and enabling rapid welding of components by industrial robots, thus improving welding efficiency.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By setting up a clamping assembly, when the second motor rotates clockwise, it drives the transmission shaft to rotate clockwise. At this time, the two movable rings slide towards each other, and the two fixed clamps can approach each other, which can clamp the workpiece to be welded, ensuring the stability of the workpiece and facilitating the welding process. When the second motor rotates counterclockwise, the two movable rings slide in opposite directions, and the two fixed clamps can separate from each other, releasing the clamped workpiece and facilitating the replacement of different workpieces to be processed. The rubber material can increase the friction between the workpiece to be welded and the fixed clamps, improving the stability of the workpiece during clamping. Furthermore, the slot design allows irregularly shaped workpieces to be welded to be stably clamped inside the anti-slip block, improving the applicability of the fixed clamp.

[0025] 2. By incorporating a cooling component, the water pump can guide the coolant from the storage tank into the injection pipe, and further into the second condensing chamber. From the top of the second condensing chamber, the coolant flows into the first condensing chamber, filling the entire clamping unit with coolant. This cools the anti-slip block inside the clamping unit and further cools the welded parts during the welding process. It prevents excessively high temperatures during welding, which can increase the fluidity of the molten metal and prevent defects such as excessively wide welds, uneven surfaces, and undercut. Furthermore, the baffle increases the flow time of the coolant within the clamping unit, ensuring the cooling effect.

[0026] 3. By setting up a rotating component, after the first motor is powered on, the first motor can drive the second pulley to rotate through the first pulley and the transmission belt. At this time, the second pulley can drive the rotating seat to rotate at the top of the support base, which allows different positions of the welding support plate to be moved to the top of the support base, facilitating welding of different positions of the workpiece to be welded on the fixing clamp, improving welding efficiency, reducing the welding difficulty of industrial robots, and during the slow rotation of the support plate, the coolant in the water tank can flow continuously. The V-shaped groove can cause the coolant to slosh significantly during the flow of coolant, which can make the temperature distribution of the coolant uniform and ensure the cooling effect. In addition, the V-shaped groove can increase the contact area between the water tank and the external environment, which can accelerate the natural cooling efficiency of the coolant in the water tank and further ensure the cooling effect. During the rotation of the water tank, the turbulence block can increase the mixing effect of the coolant and ensure the rapid cooling of the cooling water. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1 to 9 This invention provides a fixture device for welding processing of industrial robots, the technical solution of which is as follows: A fixture device for welding processing of industrial robots includes two support bases 1. Rotary seats 103 are rotatably mounted on the inner walls of the tops of both support bases 1. A welding support plate 104 is fixedly mounted on the inner sides of both rotary seats 103. A cavity 107 is formed at the top of one of the support bases 1. A rotating assembly 2 for driving the welding support plate 104 to rotate is disposed within the cavity 107. An opening slot 105 is formed at the top of the welding support plate 104. Two fixing clamps 106 are symmetrically arranged on both sides of the opening slot 105. A driving assembly 3 for driving the two fixing clamps 106 on the same side to move is also disposed at the bottom of the welding support plate 104. A cooling assembly 4 is also symmetrically disposed at the bottom of the welding support plate 104. The cooling assembly 4 includes a water tank 401 symmetrically fixedly mounted at the bottom of the welding support plate 104. The cooling assembly 4 is used to cool the two fixing clamps 106 on the same side. The rotating assembly 2 drives the workpiece to be welded on the fixing clamps 106 to rotate while simultaneously causing the water tank 401 to flip.

[0031] As one embodiment of the present invention, refer to Figures 5-6 The drive assembly 3 includes a movable frame 302 fixedly installed at the bottom of the welding support plate 104. A movable groove 303 is provided on the side wall of the movable frame 302. A drive shaft 304 is rotatably installed in the movable groove 303. A second motor 301 is fixedly installed on the side wall of the movable frame 302. The output end of the second motor 301 is fixedly connected to the central axis of the drive shaft 304. Threaded strips 305 are fixedly installed at both ends of the drive shaft 304. Movable rings 1062 are sleeved on the outer sides of both ends of the drive shaft 304. Threaded holes 1067 that are adapted to the threaded strips 305 are provided in the movable rings 1062. The movable rings 1062 are fixedly connected to the bottom end of the fixed clamp 106. The fixed clamp 106 is semi-circular. Anti-slip blocks 1061 are also fixedly installed on the inner side of the fixed clamp 106.

[0032] In this embodiment, during use, when the second motor 301 is powered on, it can drive the transmission shaft 304 to rotate within the movable groove 303. At this time, the movable ring 1062 can rotate along the threaded strip 305 on the outside of the transmission shaft 304 through the threaded hole 1067. When the second motor 301 rotates clockwise, it can drive the transmission shaft 304 to rotate clockwise. At this time, the two movable rings 1062 slide towards each other, and the two fixed clamps 106 can approach each other, which can clamp the workpiece to be welded, ensuring the stability of the workpiece and facilitating the welding. When the second motor 301 rotates counterclockwise, the two movable rings 1062 slide in opposite directions, and the two fixed clamps 106 can separate from each other, allowing the clamped workpiece to be released and facilitating the replacement of different workpieces to be processed.

[0033] As one embodiment of the present invention, refer to Figure 8 The anti-slip block 1061 is made of high-temperature resistant rubber material, and multiple slots 1063 are evenly provided on the inner side of the anti-slip block 1061.

[0034] In this embodiment, the rubber material can increase the friction between the workpiece to be welded and the fixing clamp 106, which can improve the stability of the workpiece to be welded during the clamping process. Furthermore, the slot 1063 can stably clamp irregularly shaped workpieces to be welded inside the anti-slider 1061, thereby improving the applicability of the fixing clamp 106.

[0035] As one embodiment of the present invention, refer to Figure 7 The two threaded bars 305 are symmetrically arranged about the middle position of the drive shaft 304, and the pitch of the threaded bars 305 gradually decreases from both ends of the drive shaft 304 toward the middle position.

[0036] In this embodiment, the smaller pitch of the threaded strip 305 ensures the movement accuracy of the transmission shaft 304. When the fixing clamp 106 clamps and fixes the workpiece to be welded, when the movable ring 1062 moves to the position where the threaded strip 305 has a smaller pitch, the anti-sliding block 1061 on the fixing clamp 106 can fit more tightly with the workpiece to be welded, thus ensuring the clamping effect.

[0037] As one embodiment of the present invention, refer to Figure 8 A water pump 402 is fixedly installed on the side wall at the bottom of the water storage tank 401. The inlet of the water pump 402 extends into the water storage tank 401, and the outlet of the water pump 402 is connected to a water injection pipe 405. A first condensing chamber 1064 and a second condensing chamber 1065 are provided in the fixing clamp 106. A baffle 1066 is fixedly installed between the first condensing chamber 1064 and the second condensing chamber 1065. The bottom ends of the first condensing chamber 1064 and the second condensing chamber 1065 are separated by the baffle 1066, and the top ends of the first condensing chamber 1064 and the second condensing chamber 1065 are connected.

[0038] In this embodiment, during use, the water pump 402 can introduce the coolant in the water storage tank 401 into the water injection pipe 405, and further introduce it into the second condensing chamber 1065 through the water injection pipe 405. It then flows from the top of the second condensing chamber 1065 into the first condensing chamber 1064, filling the entire fixing clamp 106 with coolant. This cools the anti-slip block 1061 inside the fixing clamp 106 and further cools the welded parts during the welding process. This prevents the welded parts from becoming too hot during the welding process, which would increase the fluidity of the molten metal and prevent defects such as excessively wide welds, uneven surfaces, and undercut. Furthermore, the baffle 1066 increases the flow time of the coolant in the fixing clamp 106, ensuring the cooling effect.

[0039] As one embodiment of the present invention, refer to Figures 8-9 The bottom end of the second condensing chamber 1065 is connected to the water injection pipe 405, and the bottom end of the first condensing chamber 1064 is connected to the return water pipe 404. The bottom end of the return water pipe 404 extends into the water storage tank 401. The return water pipes 404 and the water injection pipes 405 on the two fixing clamps 106 on the same side are connected to each other.

[0040] In this embodiment, the coolant can be recycled by the cooperation of the water injection pipe 405 and the return pipe 404, which can reduce the waste of water resources and reduce processing costs.

[0041] As one embodiment of the present invention, refer to Figure 9 The water storage tank 401 is filled with condensate. Both the upper and lower ends of the water storage tank 401 are provided with V-shaped grooves 403, and the V-shaped grooves 403 are embedded in the water storage tank 401. A baffle block 4031 is integrally provided on the inner wall of the V-shaped groove 403, and the baffle block 4031 is conical.

[0042] In this embodiment, as the water tank 401 slowly rotates with the welding support plate 104, the coolant inside the water tank 401 can flow continuously. The V-shaped groove 403 can cause the coolant to sway significantly during the flow, which can make the temperature distribution of the coolant uniform and ensure the cooling effect. In addition, the V-shaped groove 403 can increase the contact area between the water tank 401 and the external environment, which can accelerate the efficiency of natural cooling of the coolant inside the water tank 401 and further ensure the cooling effect. Furthermore, during the rotation of the water tank 401, the turbulence block 4031 can increase the mixing effect of the coolant and ensure that the cooling water cools down quickly.

[0043] As one embodiment of the present invention, refer to Figures 1-2 The rotating assembly 2 includes a first motor 204 fixedly installed at the bottom of the cavity 107. The output end of the first motor 204 is fixedly connected to a second pulley 203. A first pulley 201 is rotatably installed on the side wall at the top of the cavity 107. The central axis of the first pulley 201 is fixedly connected to the side wall of the rotating seat 103. A transmission belt 202 is sleeved on the outer side of the first pulley 201 and the second pulley 203.

[0044] In this embodiment, when the first motor 204 is powered on, the first motor 204 can drive the second pulley 203 to rotate through the first pulley 201 and the transmission belt 202. At this time, the second pulley 203 can drive the rotating seat 103 to rotate at the top of the support seat 1, so that different positions of the welding support plate 104 can be moved to the top of the support seat 1, which is convenient for welding different positions of the workpiece to be welded on the fixing clamp 106, thereby improving welding efficiency and reducing the welding difficulty of industrial robots.

[0045] As one embodiment of the present invention, refer to Figure 2 A heat sink 101 is provided on the side wall of the cavity 107 located at the first motor 204.

[0046] In this embodiment, the heat sink 101 helps to dissipate heat from the first motor 204, ensuring the long-term safe use of the first motor 204 and improving its service life.

[0047] As one embodiment of the present invention, refer to Figure 2 One of the support bases 1 is also fixedly installed with a PLC controller 102, which is electrically connected to the first motor 204, the second motor 301 and the water pump 402.

[0048] In this embodiment, the PLC controller 102 can automatically control the first motor 204, the second motor 301, and the water pump 402, which can reduce the manual operation process. Combined with the industrial robot, it can quickly weld the parts to be welded, thereby improving welding efficiency.

[0049] Working principle: First, the workpieces to be welded are placed between two fixed clamps 106 on the same side. When the second motor 301 is powered on, it drives the transmission shaft 304 to rotate in the movable groove 303. At this time, the movable ring 1062 can rotate along the threaded strip 305 on the outside of the transmission shaft 304 through the threaded hole 1067. When the second motor 301 rotates clockwise, it drives the transmission shaft 304 to rotate clockwise. At this time, the two movable rings 1062 slide towards each other, and the two fixed clamps 106 can move closer to each other, which can clamp the workpieces to be welded, ensuring their stability and facilitating welding. When the second motor 301 rotates counterclockwise, the two movable rings 1062 slide in opposite directions, and the two fixed clamps 106 can separate from each other, allowing the clamped workpieces to be released and facilitating the replacement of different workpieces to be processed. The rubber material can increase the friction between the workpiece to be welded and the fixing clamp 106, which can improve the stability of the workpiece during the clamping process. The slot 1063 can stably clamp irregularly shaped workpieces to be welded inside the anti-slider 1061, which can improve the applicability of the fixing clamp 106. The small pitch of the threaded strip 305 can ensure the movement accuracy of the drive shaft 304. When the fixing clamp 106 clamps and fixes the workpiece to be welded, when the movable ring 1062 moves to the position where the threaded strip 305 has a small pitch, the anti-slider 1061 on the fixing clamp 106 can fit more tightly with the workpiece to be welded, which can ensure the clamping effect. During the welding process, the water pump 402 can introduce the coolant in the water storage tank 401 into the water injection pipe 405, and further introduce it into the second condensing chamber 1065 through the water injection pipe 405. Then, it flows from the top of the second condensing chamber 1065 into the first condensing chamber 1064, so that the entire fixing clamp 106 is filled with coolant. This can cool down the anti-slip block 1061 on the inside of the fixing clamp 106, and further cool down the welded parts during the welding process. This can prevent the welded parts from becoming too hot during the welding process, which would increase the fluidity of the molten metal. It can also prevent defects such as excessively wide welds, uneven surfaces, and undercut. In addition, the baffle 1066 increases the flow time of the coolant in the fixing clamp 106, ensuring the cooling effect. With the cooperation of the water injection pipe 405 and the return water pipe 404, the coolant can be recycled, which can reduce water waste and reduce processing costs. As the water tank 401 slowly rotates with the welding support plate 104, the coolant inside the water tank 401 can flow continuously. The V-shaped groove 403 can cause the coolant to slosh around significantly during the flow, which can make the temperature distribution of the coolant uniform and ensure the cooling effect. In addition, the V-shaped groove 403 can increase the contact area between the water tank 401 and the external environment, which can accelerate the efficiency of natural cooling of the coolant inside the water tank 401 and further ensure the cooling effect. Furthermore, during the rotation of the water tank 401, the turbulence block 4031 can increase the mixing effect of the coolant and ensure that the cooling water cools down quickly. During welding, when the first motor 204 is powered on, it drives the second pulley 203 to rotate via the first pulley 201 and the transmission belt 202. The second pulley 203 then drives the rotating seat 103 to rotate at the top of the support seat 1, allowing different positions of the welding support plate 104 to be moved to the top of the support seat 1. This facilitates welding at different positions on the workpiece to be welded on the fixing clamp 106, improving welding efficiency and reducing the welding difficulty for the industrial robot. The heat sink 101 helps dissipate heat from the first motor 204, ensuring its long-term safe use and extending its service life. The PLC controller 102 automatically controls the first motor 204, the second motor 301, and the water pump 402, reducing manual operation and enabling rapid welding of the workpiece by the industrial robot, thus improving welding efficiency.
