Description

Technical Field

[0001] This invention relates to the field of motor manufacturing technology, and more specifically to an automated arc welding equipment for the production of general-purpose servo motors. Background Technology

[0002] The terms "motor" and "electric motor" are often used interchangeably in everyday life, but there are subtle differences between them. In the field of electrical engineering, "electric motor" is the more formal term, while "motor" is the informal, colloquial term. Both refer to a device that converts electrical energy into mechanical energy. In addition to ordinary motors, there is a type of explosion-proof motor that uses high-strength materials to make the casing, can withstand the pressure generated by an internal explosion, and prevents the explosion from spreading to the external environment. These motors are suitable for flammable and explosive environments such as petroleum, chemical, coal mining, pharmaceutical, and food processing.

[0003] Existing explosion-proof motors typically have numerous heat dissipation fins or plates welded to their exterior to dissipate heat from the interior and reduce the impact of internal heat accumulation on motor operation. However, during the welding process of the motor housing, personnel must manually hold the heat dissipation fins and welding gun to perform the welding. For the welding of explosion-proof motor housings, manual welding lacks continuity, and poor welding quality can lead to a decrease in the thermal conductivity and explosion-proof performance of the motor housing. Therefore, an automated arc welding equipment for general-purpose servo motor production is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the problems that manual welding has poor continuity and poor welding quality, which can lead to a decrease in the thermal conductivity and explosion-proof performance of the motor housing. This invention provides a general-purpose automated arc welding equipment for servo motor production.

[0005] To achieve the above objectives, the present invention specifically adopts the following technical solution: An automated arc welding device for general-purpose servo motor production includes a welding table. An arc-shaped slide rail is fixedly mounted on the top of the welding table. Two symmetrically arranged locking semi-rings are rotatably mounted inside the arc-shaped slide rail. A single motor housing is placed inside the two locking semi-rings. Multiple fin welding holes are formed on the periphery of the motor housing. Locking ears are fixedly mounted on the sidewalls of both ends of each locking semi-ring. Locking electric push rods are fixedly mounted at the bottom of the two locking ears on one side. The telescopic ends of the two locking electric push rods are fixedly connected to the two locking ears on the other side. Multiple evenly distributed meshing teeth are fixedly mounted on the outer sidewall of each locking semi-ring. A steering motor is fixedly mounted on one side of the bottom of the arc-shaped slide rail. A steering shaft is driven by the output end of the steering motor. One end of the steering shaft extends into the interior of the arc-shaped slide rail and is fixedly mounted with multiple steering gears, all of which mesh with the meshing teeth.

[0006] Furthermore, anti-detachment short slide rails are slidably installed at both ends of the arc-shaped slide rail, and the two anti-detachment short slide rails are symmetrically arranged. Push rod brackets are fixedly installed on both sides of the arc-shaped slide rail, and horizontally arranged anti-detachment electric push rods are fixedly installed on the top of the push rod brackets. The telescopic ends of the two anti-detachment electric push rods are respectively fixedly connected to the two anti-detachment short slide rails. A positioning frame is fixedly installed on the side of the arc-shaped slide rail away from the fin placement plate, and a positioning turntable is rotatably installed on the side of the positioning frame facing the motor housing.

[0007] Furthermore, the bottom of the motor housing is provided with a feeding assembly for batch storage of the heat dissipation fins required for the motor housing. The feeding assembly includes a fin placement plate disposed at the bottom of the motor housing. Pitch shafts are fixedly installed on both sides of the fin placement plate. The fin placement plate is located between the arc-shaped slide rail and the gantry lifting frame. A first horizontal linear guide rail is fixedly installed on the top of the welding table. Two first electric sliders are driven and installed on the top of the first horizontal linear guide rail. A second horizontal linear guide rail is fixedly installed on the top of each of the first electric sliders. A second electric slider is driven and installed on the top of each of the second horizontal linear guide rails. A bearing bracket is fixedly installed on the top of each of the second electric sliders. The two pitch shafts are rotatably mounted on the two bearing brackets respectively. The top of the fin placement plate has multiple evenly distributed placement slots for storing the heat dissipation fins of the motor housing.

[0008] Furthermore, a support bracket is fixedly installed on the top of the welding table, and a delivery tube inclined toward the fin placement plate is fixedly installed at the top of the support bracket. A pitch motor is fixedly installed on one side of one of the bearing brackets, and the output shaft of the pitch motor is drivenly connected to the pitch axis on the same side.

[0009] Furthermore, an electric sliding door is fixedly installed on one side of the bottom end of the delivery tube, and the driving end of the electric sliding door extends into the interior of the delivery tube. An oblique linear module parallel to the delivery tube is fixedly installed on one side of the delivery tube, and a laser rangefinder is fixedly installed on the driving end of the oblique linear module. A measuring hole corresponding to the position of the laser rangefinder is opened on one side of the delivery tube.

[0010] Furthermore, the bottom of the feeding assembly is provided with a loading assembly for feeding the heat dissipation fins stored inside the feeding assembly into the fin welding holes. The loading assembly includes a lifting telescopic arm disposed at the bottom of the fin placement plate. The lifting telescopic arm is fixedly installed inside the welding table. The telescopic end of the lifting telescopic arm extends to the bottom of the fin placement plate and is fixedly installed with a lifting fork. The bottom of the fin placement plate is provided with a plurality of vertically penetrating clearance holes, the positions of which correspond to the positions of the plurality of placement slots.

[0011] Furthermore, thin-walled airbags are fixedly installed on both inner walls of the lifting fork frame, and a circulating air pump is fixedly installed on the top of the welding table. An air supply pipe is fixedly installed on the air supply end of the circulating air pump, and one end of the air supply pipe extends into the interior of the lifting fork frame and is connected to the two thin-walled airbags.

[0012] Furthermore, the top of the welding station is provided with an automatic welding mechanism for automatically welding the heat dissipation fins of the motor housing. The automatic welding mechanism includes a gantry lifting frame fixedly installed on the top of the welding station. A horizontally arranged multi-stage telescopic arm is fixedly installed on the top of the gantry lifting frame. A horizontal linear module is fixedly installed at the telescopic end of the multi-stage telescopic arm. A vertical telescopic arm is fixedly installed at the drive end of the horizontal linear module. A deflection motor is fixedly installed on one side of the telescopic end of the vertical telescopic arm. A deflection frame is fixedly installed on the output shaft of the deflection motor. An electric welding clamp is fixedly installed on the side of the deflection frame facing the motor housing. A welding rod is held in the electric welding clamp.

[0013] The beneficial effects of this invention are as follows: 1. The present invention sets up an automatic welding mechanism so that after the fins are fed into the fin welding holes, the automatic welding mechanism welds all the fins inside the fin welding holes. At this time, the gantry lifting frame drives the multi-stage telescopic arm to lift upward, so that the welding clamp and welding rod are on the top of the motor housing, and then the joint between the outer wall of the motor housing and the fins is fully welded, thereby realizing automated internal and external full welding. 2. The present invention significantly improves the connection strength between the fins and the motor housing by using a plug-in welding method. The full welding method inside and outside ensures the sealing performance and explosion-proof performance of the motor housing. During the full welding of the outer wall of the motor housing, the feeding mechanism is in a reset idle state, at which time the above-mentioned fin replenishment operation can be carried out, thereby improving the continuity of welding and reducing the time spent on handover between different work stations. 3. By setting up a laser rangefinder, when the fin welding hole sizes on the motor housing are not uniform and different sizes of heat dissipation fins need to be welded, the laser rangefinder measures the length of the fins, aligns the corresponding placement slot with the delivery tube, and then allows the fins to fall into the corresponding placement slots. This achieves automatic classification, storage, and position recording of the fins, making it convenient for the feeding mechanism to push the fins of the correct size into the fin welding holes.

[0019] like Figures 1 to 12 As shown, a general-purpose automated arc welding equipment for servo motor production includes a welding table 1, such as... Figure 1 , Figure 2 , Figure 3 As shown, specifically, an arc-shaped slide rail 2 is fixedly installed on the top of the welding table 1. Two symmetrically arranged locking semi-rings 3 are rotatably installed inside the arc-shaped slide rail 2. The same motor housing 4 is placed inside the two locking semi-rings 3. Multiple fin welding holes 401 are opened on the periphery of the motor housing 4, such as... Figure 4 As shown, locking lugs 5 are fixedly installed on both ends of the locking half-ring 3. Locking electric push rods 6 are fixedly installed at the bottom of the two locking lugs 5 on one side. The telescopic ends of the two locking electric push rods 6 are fixedly connected to the two locking lugs 5 on the other side. Multiple evenly distributed meshing teeth 7 are fixedly installed on the outer ring sidewall of the locking half-ring 3, such as... Figure 3 As shown, a steering motor 8 is fixedly installed on one side of the bottom of the arc-shaped slide rail 2. The output end of the steering motor 8 drives the steering shaft 9. One end of the steering shaft 9 extends into the interior of the arc-shaped slide rail 2 and is fixedly installed with multiple steering gears 10. All steering gears 10 mesh with meshing teeth 7.

[0020] In this embodiment, two locking electric push rods 6 are respectively assembled on both sides of one locking half ring 3 via locking ears 5. The locking ears 5 on both sides of the locking half ring 3 are provided with through holes, so that the telescopic end of the locking electric push rod 6 can pass through the through holes and be fixedly connected to the two locking ears 5 on the other locking half ring 3, thereby realizing the automatic opening and closing of the two locking half rings 3. The interior of the locking half ring 3 can be welded or screwed with a positioning structure that is compatible with the current model of motor housing 4, so that the steering of the locking half ring 3 is more accurate.

[0021] More specifically, when this general-purpose servo motor production automated arc welding equipment is in use, the steering motor 8 drives the steering gear 10 to rotate, which in turn drives the two locking half-rings 3 inside the arc-shaped slide rail 2 to rotate, so that the two locking half-rings 3 are correctly positioned vertically. Then, the two locking electric push rods 6 at the bottom drive the upper locking half-ring 3 to lift upward, thereby separating the two locking half-rings 3. At this time, the motor housing 4 to be welded is placed between the two locking half-rings 3. The locking electric push rods 6 drive the upper locking half-ring 3 to reset, clamping and fixing the motor housing 4, so that the steering motor 8 can drive the motor housing 4 to rotate, thereby facilitating welding at various parts of the motor housing 4.

[0022] like Figure 3 As shown, anti-detachment short slide rails 36 are slidably installed at both ends of the arc-shaped slide rail 2. Specifically, the two anti-detachment short slide rails 36 are symmetrically arranged. Push rod brackets 37 are fixedly installed on both sides of the arc-shaped slide rail 2. Horizontally arranged anti-detachment electric push rods 38 are fixedly installed on the top of the push rod brackets 37. The telescopic ends of the two anti-detachment electric push rods 38 are fixedly connected to the two anti-detachment short slide rails 36 respectively. A positioning frame 39 is fixedly installed on the side of the arc-shaped slide rail 2 away from the fin placement plate 24. A positioning turntable 40 is rotatably installed on the side of the positioning frame 39 facing the motor housing 4.

[0023] More specifically, when the motor housing 4 is clamped and fixed, the positioning turntable 40 on one side of the arc-shaped slide rail 2 will intercept the motor housing 4 and play a positioning role. At the same time, after the motor housing 4 is clamped, the anti-detachment electric push rods 38 on both sides of the arc-shaped slide rail 2 will drive the two anti-detachment short slide rails 36 to slide towards the locking half ring 3, thereby fitting the locking half ring 3 and limiting the locking half ring 3 to prevent the locking half ring 3 from moving up and down, which would affect the accuracy of the rotation of the locking half ring 3 and the motor housing 4.

[0024] The bottom of the motor housing 4 is equipped with a feeding assembly for bulk storage of the heat dissipation fins required for the motor housing 4, such as... Figure 1 , Figure 7 , Figure 8As shown, specifically, the feeding assembly includes a fin placement plate 24 located at the bottom of the motor housing 4. Pitch shafts 23 are fixedly installed on both sides of the fin placement plate 24. The fin placement plate 24 is located between the arc-shaped slide rail 2 and the gantry lifting frame 11. A first horizontal linear guide rail 19 is fixedly installed on the top of the welding table 1. Two first electric sliders 20 are driven and installed on the top of the first horizontal linear guide rail 19. A second horizontal linear guide rail 21 is fixedly installed on the top of each of the first electric sliders 20. A second electric slider 22 is driven and installed on the top of each of the second horizontal linear guide rails 21. A bearing bracket is fixedly installed on the top of each of the second electric sliders 22. The two pitch shafts 23 are rotatably mounted on the two bearing brackets respectively. Multiple evenly distributed placement slots 2401 are opened on the top of the fin placement plate 24. The placement slots 2401 are used to store the heat dissipation fins of the motor housing 4.

[0025] More specifically, by setting up a feeding assembly, the feeding slot 2401 at the top of the fin placement plate 24 can hold a large number of heat dissipation fins of different lengths, which are used to provide fins for the feeding mechanism. With the drive of the first horizontal linear guide rail 19 and the first electric slider 20, the fin placement plate 24 can move horizontally, thereby changing the position of the feeding slot 2401, so that the feeding mechanism can send the heat dissipation fins into the fin welding hole 401 each time.

[0026] like Figure 1 , Figure 11 As shown, a support bracket 27 is fixedly installed on the top of the welding table 1. Specifically, a delivery tube 28, inclined towards the fin placement plate 24, is fixedly installed at the top of the support bracket 27. Figure 7 As shown, a pitch motor 29 is fixedly installed on one side of one of the bearing brackets, and the output shaft of the pitch motor 29 is drivenly connected to the pitch shaft 23 on the same side.

[0027] More specifically, by setting up the delivery pipe 28, when replenishing the heat dissipation fins, the pitch motor 29 drives the fin placement plate 24 to flip upward. Then, the second electric slider 22 carries the fin placement plate 24 toward the delivery pipe 28, so that the fin placement plate 24 docks with the delivery pipe 28. At this time, the workers or conveying equipment can transport the heat dissipation fins into the placement slots 2401 through the delivery pipe 28. Then, with the drive of the first horizontal linear guide rail 19 and the first electric slider 20, the fin placement plate 24 moves horizontally continuously, so that each placement slot 2401 docks with the delivery pipe 28 in sequence, thereby replenishing the heat dissipation fins for subsequent feeding.

[0028] like Figure 11 , Figure 12As shown, specifically, an electric sliding door 30 is fixedly installed on one side of the bottom end of the delivery tube 28, the drive end of the electric sliding door 30 extends into the interior of the delivery tube 28, an oblique linear module 31 parallel to the delivery tube 28 is fixedly installed on one side of the delivery tube 28, a laser rangefinder 32 is fixedly installed on the drive end of the oblique linear module 31, and a measuring hole 2801 corresponding to the position of the laser rangefinder 32 is opened on one side of the delivery tube 28.

[0029] More specifically, by setting up a laser rangefinder 32, when the size of the fin welding holes 401 on the motor housing 4 is not uniform and different sizes of heat dissipation fins need to be welded, when the heat dissipation fins are placed into the delivery tube 28, the fins will be intercepted by the electric sliding door 30 at the bottom. Then, the inclined linear module 31 drives the laser rangefinder 32 to move along the measuring hole 2801 to measure the length of the fins inside the delivery tube 28, thereby causing the fin placement plate 24 to move horizontally so that the placement slot 2401 of the corresponding size aligns with the delivery tube 28. At this time, the electric sliding door 30 opens, allowing the fins to fall into the corresponding placement slot 2401, thereby realizing the automatic classification, storage and position recording of the fins, which facilitates the feeding mechanism to push the fins of the correct size into the fin welding holes 401.

[0030] The bottom of the feeding assembly is equipped with a loading component for feeding the heat dissipation fins stored inside the feeding assembly into the fin welding holes 401, such as... Figure 1 , Figure 9 As shown, specifically, the feeding assembly includes a lifting telescopic arm 25 disposed at the bottom of the fin placement plate 24. The lifting telescopic arm 25 is fixedly installed inside the welding table 1. The telescopic end of the lifting telescopic arm 25 extends to the bottom of the fin placement plate 24 and is fixedly installed with a lifting fork 26. The bottom of the fin placement plate 24 has multiple vertically penetrating clearance holes 2402, and the positions of the multiple clearance holes 2402 correspond to the positions of the multiple placement slots 2401.

[0031] In this embodiment, the length and thickness of the placement slots 2401 on the fin placement plate 24 can be customized according to the actual size of the heat dissipation fins. Different lengths of placement slots 2401 can be opened on the fin placement plate 24 to store heat dissipation fins of different lengths, ensuring that the center position of each heat dissipation fin is consistent with the center position of the fin placement plate 24. Each clearance hole 2402 is connected to a placement slot 2401, and the clearance holes 2402 are all located at the center position of the fin placement plate 24. Figure 10 As shown, the lifting fork 26 is a Y-shaped fork, and the height of the fork at the top is less than the width of the heat dissipation fins.

[0032] More specifically, by setting up a feeding mechanism, the steering motor 8 drives the motor housing 4 to rotate, aligning the first fin welding hole 401 with the fin placement plate 24. At this time, the fin placement plate 24 moves horizontally, causing the placement slot 2401 containing the corresponding size heat dissipation fins to move directly below the fin welding hole 401. Then, the lifting telescopic arm 25 drives the lifting fork 26 to lift and enter the clearance hole 2402 to fork the heat dissipation fins at the top, thereby sending the fins from the placement slot 2401 to the fin welding hole 401, so that the top of the fins is inside the motor housing 4 and the bottom is outside, realizing the feeding and fixing of the motor housing 4, waiting for welding to proceed.

[0033] like Figure 9 , Figure 10 As shown, specifically, thin-walled airbags 33 are fixedly installed on both inner walls of the lifting fork 26, and a circulating air pump 34 is fixedly installed on the top of the welding table 1. An air supply pipe 35 is fixedly installed on the air supply end of the circulating air pump 34, and one end of the air supply pipe 35 extends into the interior of the lifting fork 26 and is connected to the two thin-walled airbags 33.

[0034] More specifically, by setting up thin-walled airbags 33, when the lifting fork 26 holds the fins, the circulating air pump 34 supplies air to the thin-walled airbags 33 on both sides, so that the thin-walled airbags 33 press the fins tightly and prevent the fins from loosening and falling off when loading.

[0035] The top of the welding station 1 is equipped with an automatic welding mechanism for automatically welding the heat dissipation fins of the motor housing 4, such as... Figure 1 , Figure 5 As shown, specifically, the automatic welding mechanism includes a gantry lifting frame 11 fixedly installed on the top of the welding table 1. A horizontally arranged multi-stage telescopic arm 12 is fixedly installed on the top of the gantry lifting frame 11. A horizontal linear module 13 is fixedly installed at the telescopic end of the multi-stage telescopic arm 12, and a vertical telescopic arm 14 is fixedly installed at the drive end of the horizontal linear module 13. Figure 6 As shown, a deflection motor 16 is fixedly installed on one side of the telescopic end of the vertical telescopic arm 14. A deflection frame 15 is fixedly installed on the output shaft of the deflection motor 16. A welding clamp 17 is fixedly installed on the side of the deflection frame 15 facing the motor housing 4. A welding rod 18 is held on the welding clamp 17.

[0036] More specifically, by setting up an automatic welding mechanism, after the fins are fed into the fin welding holes 401, the multi-stage telescopic arm 12 drives the welding clamp 17 to extend into the interior of the motor housing 4. Then, the horizontal linear module 13, the vertical telescopic arm 14, and the deflection motor 16 adjust the position and angle of the welding clamp 17, so that the welding clamp 17 carries the welding rod 18 to weld the joint between the fins and the fin welding holes 401. At the same time, with the extension and retraction of the multi-stage telescopic arm 12 and the control of the horizontal linear module 13, the vertical telescopic arm 14, etc., the welding rod 18 performs full welding on the joint between the fins and the inner wall of the motor housing 4. Afterwards, the automatic welding mechanism, the feeding mechanism, etc., alternately reset and perform a second round of feeding and welding. Until all fins are welded inside the fin welding holes 401, the gantry lifting frame 11 drives the multi-stage telescopic arm 12 to lift upwards, so that the welding clamp 17 and welding rod 18 are on top of the motor housing 4, and then the joint between the outer wall of the motor housing 4 and the fins is fully welded, thereby realizing automated internal and external full welding. The plug-in welding method of the fins and the motor housing 4 greatly improves the connection strength between the two. The internal and external full welding method ensures the sealing performance and explosion-proof performance of the motor housing 4. During the full welding of the outer wall of the motor housing 4, the feeding mechanism is in a reset idle state. At this time, the above-mentioned fin supplementation operation can be carried out, thereby improving the continuity of welding and reducing the time spent on handover between different work stations.

[0037] In summary: Before welding: The steering motor 8 drives the two locking half-rings 3 to rotate, aligning them vertically. Then, the two locking electric push rods 6 at the bottom drive the upper locking half-ring 3 upwards, separating the two locking half-rings 3. At this point, the motor housing 4 to be welded is placed between the two locking half-rings 3. The locking electric push rods 6 drive the upper locking half-ring 3 to reset, clamping and fixing the motor housing 4. The anti-detachment electric push rods 38 on both sides of the arc-shaped slide rail 2 drive the two anti-detachment short slide rails 36 towards the locking half-rings 3. The movement causes the locking half-ring 3 to be in contact with the locking half-ring 3 and to be limited. The steering motor 8 drives the motor housing 4 to rotate, aligning the first fin welding hole 401 with the fin placement plate 24. At this time, the fin placement plate 24 moves horizontally, causing the placement slot 2401 containing the corresponding size heat dissipation fins to move directly below the fin welding hole 401. Then, the lifting telescopic arm 25 drives the lifting fork 26 to lift and enter the clearance hole 2402 to fork the heat dissipation fins at the top, thereby sending the fins from the placement slot 2401 to the fin welding hole 401. During welding: The multi-stage telescopic arm 12 drives the welding clamp 17 to extend into the motor housing 4. Then, the horizontal linear module 13, the vertical telescopic arm 14, and the deflection motor 16 adjust the position and angle of the welding clamp 17 respectively, so that the welding clamp 17 carries the welding rod 18 to weld the joint between the fin and the fin welding hole 401. At the same time, with the extension and retraction of the multi-stage telescopic arm 12 and the control of the horizontal linear module 13, the vertical telescopic arm 14, etc., the welding rod 18 is fully welded to the joint between the fin and the inner wall of the motor housing 4. After that, the automatic welding mechanism, the feeding mechanism, etc. are alternately reset and a second round of feeding and welding is performed until all the fins are welded inside the fin welding hole 401. At this time, the gantry lifting frame 11 drives the multi-stage telescopic arm 12 to lift upward, so that the welding clamp 17 and the welding rod 18 are at the top of the motor housing 4, and then the joint between the outer wall of the motor housing 4 and the fin is fully welded. After welding: During the full welding of the outer wall of the motor housing 4, the pitch motor 29 drives the fin placement plate 24 to flip upward. Then, the second electric slider 22 carries the fin placement plate 24 toward the delivery tube 28, so that the fin placement plate 24 docks with the delivery tube 28. At this time, the workers or conveying equipment can deliver the heat dissipation fins into the placement slot 2401 through the delivery tube 28. Then, with the drive of the first horizontal linear guide rail 19 and the first electric slider 20, the fin placement plate 24 moves horizontally continuously, so that each placement slot 2401 docks with the delivery tube 28 in sequence, so that the fins fall into the corresponding placement slot 2401, thereby realizing the automatic classification, storage and position recording of the fins.
