Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of motor welding equipment, and particularly relates to a motor front end cover and shell welding device. BACKGROUND

[0002] A motor refers to an electromagnetic device for realizing electric energy conversion or transmission according to electromagnetic induction law, and is divided into a direct current motor and an alternating current motor. Basic components of the motor include a stator, a rotor, an end cover, a shell, a fan cover and the like. In motor production, in order to improve the firmness and protection effect of the motor shell, the motor shell and the front end cover are welded and fixed, so that the motor can better protect the inside thereof.

[0003] In the welding of the motor shell and the end cover by the common welding equipment, in order to facilitate the welding operation of the workers, the motor shell and the end cover are welded and fixed at the connecting position of the outer walls. However, in order to improve the heat dissipation efficiency, the outer walls of the motor shell and the front end cover are provided with a large number of heat dissipation ribs. Therefore, when the welding equipment is used to weld and fix the motor shell and the end cover at the connecting position of the outer walls, the large number of heat dissipation ribs will affect the welding operation.

A spring is installed inside the fixed hole. The two ends of the spring are respectively installed on the end of the movable plate inside the fixed hole and on the inner wall of the fixed hole.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, during use, the operator can replace the welding gun or flame gun on the hydraulic telescopic base according to the usage situation. Because several hydraulic telescopic bases are installed on the outer wall of the fixed sleeve, the operator can also install welding guns and flame guns at the same time. During use, the operator does not need to manually replace the welding gun or flame gun, which improves the welding efficiency of the housing and end cover. Several hydraulic telescopic bases can also be equipped with flame guns or welding guns at the same time, so that several flame guns or welding guns can weld the connection position of the housing and end cover at the same time, improving the welding efficiency of the end cover and housing. Welding is also performed on the connection position of the inner wall of the housing and end cover, which makes it convenient for the operator to grind and polish the weld position of the inner wall of the housing. At the same time, the weld position can also be protected during use.

[0016] 2. In this invention, when there is a deviation between the position of the flame gun and the welding piece, the operator can push the fixed shell to rotate on the outer wall of the mounting shaft, and push the end cover, welding piece and housing to rotate and move until the flame gun is inside the welding piece and corresponds to the welding piece. After the operator has adjusted the position of the flame gun and the welding piece, the operator rotates the internal thread block on the outer wall of the mounting shaft near the mounting plate, and fixes the position of the fixed shell through the internal thread block. During use, the position of the flame gun and the welding gun can be adjusted at any time according to the usage situation, which makes it convenient for the operator to accurately weld the connection position of the housing and the end cover.

[0017] 3. In this invention, the limiting plate on the fixing plate of the outer wall of the fixed shell will be inserted between two adjacent heat dissipation fins on the outer wall of the end cover as the end cover moves. The limiting plate can play a good role in limiting the position of the end cover through the heat dissipation fins on the outer wall of the end cover. The outer wall of the welding piece abuts against the side of several limiting plates near the mounting shaft. In use, several limiting plates can not only play a good role in limiting the position of the end cover, but also play a good role in supporting and fixing the position of the welding piece. The limiting plate can play a good role in reinforcing, supporting and connecting the position of the end cover and the housing through the heat dissipation fins. When the end cover rotates, it can drive the housing to rotate at the same time, preventing the displacement of the connection position between the end cover and the housing during use.

[0018] 4. In this invention, when workers weld the casing and end cap using a blowtorch and welding torch, the air purifier located inside the mounting hole at the end of the mounting shaft away from the mounting plate can absorb and purify the gases generated during welding through several air inlets. The purified air is then discharged to the outside through the end of the mounting shaft away from the mounting plate. This prevents harmful gases generated during welding from affecting the health of surrounding workers. At the same time, when the blowtorch is used to weld the casing and end cap, the heat emitted when the welding piece melts and then solidifies is absorbed, which can quickly cool the inside of the casing and prevent the high temperature generated by the blowtorch from affecting the inner wall of the casing and end cap. This provides good protection for the casing and end cap during use. Attached Figure Description

Base plates 2 are mounted on both sides of the bottom end of the mounting plate 1. A mounting shaft 8 is mounted on the side of the mounting plate 1 near the base plate 2. A fixing shell 12 and a mounting sleeve 17 are threaded onto both ends of the mounting shaft 8, respectively. The fixing shell 12 is located on the outer wall of the mounting shaft 8 near the mounting plate 1. A housing 3 and an end cover 4 are mounted on the side of the mounting plate 1. The end cover 4 is movably mounted on the outer wall of the mounting shaft 8 at a position on the side of the fixing shell 12. The mounting sleeve 17 is located inside the housing 3.

The two ends of the limiting plate 15 are located between two adjacent heat dissipation fins on the end cover 4 and the outer wall of the housing 3, respectively.

[0024] As a technical optimization of the present invention, a fixed sleeve 13 is rotatably installed on the outer wall of the mounting sleeve 17. An annular storage groove 22 is opened on the side of the mounting sleeve 17 away from the end cover 4. Several hydraulic telescopic seats 18 are installed on the outer wall of the fixed sleeve 13. A welding gun 19 is installed at the end of the hydraulic telescopic seat 18 near the inner wall of the housing 3. Several connecting blocks 21 that match the hydraulic telescopic seats 18 are installed on the side of the fixed sleeve 13 away from the end cover 4. The connecting blocks 21 are connected to the welding gun 19 through the hydraulic telescopic seats 18. When in use, the operator can wrap the welding wire for welding inside the storage groove 22, and one end of the welding wire is connected to the welding gun 19 through the connecting blocks 21 and the hydraulic telescopic seats 18, so that the welding gun 19 can be used to weld the opposite surfaces of the housing 3 and the end cover 4.

[0025] As a technical optimization of the present invention, a welding piece 34 is installed between the opposite surfaces of the end cover 4 and the housing 3. The two sides of the welding piece 34 abut against the opposite surfaces of the end cover 4 and the housing 3, respectively. The outer wall of the welding piece 34 abuts against the side of several limiting plates 15 near the end cover 4. An arc-shaped groove is provided on the inner wall of the storage groove 22. During use, the operator can heat the welding piece 34 through external heating equipment to melt the welding piece 34 at the opposite surface of the housing 3 and the end cover 4, so as to achieve the purpose of welding and fixing the housing 3 and the end cover 4 together. During use, it can increase the welding contact area between the housing 3 and the end cover 4 and improve the firmness of the welding position between the housing 3 and the end cover 4.

[0026] As a technical optimization of the present invention, a mounting hole 26 is provided at the end of the mounting shaft 8 away from the mounting plate 1. An air purifier 20 is installed inside the mounting hole 26. A plurality of air inlets 25 are provided at the end of the inner wall of the mounting hole 26 near the mounting plate 1. The air purifier 20 is interconnected with the interior of the housing 3 through the air inlets 25. When the welding gun 19 welds the connection position of the housing 3 and the end cover 4, the welding fumes can enter the interior of the air purifier 20 through the air inlets 25, which facilitates the purification of the fumes generated during welding.

[0027] As a technical optimization of the present invention, internal thread blocks 16 are threadedly installed on both sides of the mounting sleeve 17 and on the side of the fixed shell 12 near the mounting plate 1 on the outer wall of the mounting shaft 8. An annular second sliding groove 23 is provided on the outer wall of the mounting sleeve 17. A second electric slider 24 is installed on the inner wall of the fixed sleeve 13. The second electric slider 24 is slidably installed in the second sliding groove 23. The second electric slider 24 can drive the fixed sleeve 13 and several welding guns 19 to rotate inside the housing 3, so that the welding guns 19 can be used to weld different connection positions of the housing 3 and the end cover 4.

[0028] As a technical optimization of the present invention, the top of the opposite surfaces of the two base plates 2 are provided with arc-shaped grooves 5 along the length direction. The bottom ends of the outer walls on both sides of the end cap 4 and the housing 3 are respectively located inside the two arc-shaped grooves 5. The top of the two base plates 2 away from the opposite surfaces are provided with placement grooves 7 along the length direction. The bottom ends of the placement grooves 7 are provided with screw holes 9. The workers can fix the two base plates 2 to the ground with fixing bolts and screw holes 9, thereby improving the stability of the base plates 2 and the mounting shaft 8 during use.

[0029] As a technical optimization of the present invention, a slot 31 is provided on the inner wall of the two placement slots 7 away from the mounting plate 1. The slot 31 penetrates the bottom plate 2 and the arc-shaped groove 5. A baffle 30 is installed between the two bottom plates 2 away from the mounting plate 1. The two ends of the baffle 30 are respectively located between the two slots 31. The middle side of the baffle 30 abuts against the end of the housing 3 away from the end cover 4. In use, the slot 31 can limit the baffle 30 and store the clamping blocks 35 on the two moving plates 27.

[0030] As a technical optimization of the present invention, the mounting plate 1 has a first sliding groove 10 at both ends on the side near the mounting shaft 8. A first electric slider 11 is slidably installed inside the first sliding groove 10. The end of the first electric slider 11 away from the inner wall of the first sliding groove 10 passes through the first sliding groove 10 and is rotatably mounted with a protective plate 6. The two protective plates 6 are located on both sides of the housing 3. During use, the operator can adjust the height of the end of the protective plate 6 near the mounting plate 1 through the first electric slider 11.

[0031] As a technical optimization of the present invention, a fixing hole 28 is provided at the end of the protective plate 6 away from the mounting plate 1 along the length direction. The end of the fixing hole 28 away from the mounting plate 1 passes through the protective plate 6. A movable plate 27 is slidably installed inside the fixing hole 28. A clamping block 35 is installed on the side of the movable plate 27 away from the mounting plate 1. The side of the clamping block 35 abuts against the end of the housing 3 away from the end cover 4. The clamping block 35 can cooperate with the fixed housing 12 to clamp and fix the housing 3 and the end cover 4.

[0032] As a technical optimization of the present invention, both the protective plate 6 and the movable plate 27 are located above the placement groove 7. The side of the movable plate 27 is provided with a sliding hole 29 along its length. Two support rods 33 are slidably installed inside the sliding hole 29. Both support rods 33 are installed on the inner wall of the fixed hole 28 away from the mounting plate 1. A spring 32 is installed inside the fixed hole 28. The two ends of the spring 32 are respectively installed on the end of the movable plate 27 located inside the fixed hole 28 and on the inner wall of the fixed hole 28. The two support rods 33 can cooperate with each other during use to guide and support the movable plate 27.

[0033] In use, the operator first threaded one of the internal threaded blocks 16 and the fixing shell 12 onto the outer wall of the mounting shaft 8. The position of the fixing shell 12 is then adjusted by rotating it, moving it to a position near the mounting plate 1 on the outer wall of the mounting shaft 8. The operator then places the end cap 4 onto the mounting shaft 8 and pushes it towards the fixing shell 12 until the side of the end cap 4 abuts against the fixing shell 12, or until the bottom sides of the end cap 4 abut against the inner walls of the arc-shaped grooves 5 on the two base plates 2. As the operator moves the end cap 4, the limiting plate 15 on the fixing plate 14 on the outer wall of the fixing shell 12 inserts between two adjacent heat dissipation fins on the outer wall of the end cap 4. The limiting plate 15 effectively limits the position of the end cap 4 through the heat dissipation fins on its outer wall, preventing rotation during use.

[0034] After the workers have installed the end cap 4, they put the welding piece 34 to be used on the mounting shaft 8 and make the side of the welding piece 34 abut against the end cap 4. At the same time, the welding piece 34 is located between several limiting plates 15, and the outer wall of the welding piece 34 abuts against the side of the several limiting plates 15 near the mounting shaft 8. In use, the several limiting plates 15 can not only provide good position limitation for the end cap 4, but also provide good support and position fixation for the welding piece 34.

[0035] The operator places the housing 3 onto the mounting shaft 8, with both bottom ends of the housing 3 located inside the arc groove 5. The operator can then push the housing 3 to move it until the end of the housing 3 near the end cover 4 abuts against the side of the welding piece 34. During use, the two sides of the welding piece 34 abut against the opposite surfaces of the end cover 4 and the housing 3, respectively. At the same time, because the outer walls of the end cover 4 and the housing 3 abut against the inner wall of the arc groove 5, the housing 3 and the end cover 4 are well guided during use, making the connection between the housing 3 and the end cover 4 more precise. When the housing 3 moves, the end of the limiting plate 15 away from the fixed shell 12 is inserted between two adjacent heat dissipation fins on the outer wall of the housing 3, so that the two ends of the limiting plate 15 are respectively located between two adjacent heat dissipation fins on the end cover 4 and the outer wall of the housing 3. The limiting plate 15 can play a good role in reinforcing, supporting and connecting the end cover 4 and the housing 3 through the heat dissipation fins. When the end cover 4 rotates, it can drive the housing 3 to rotate at the same time, preventing displacement of the connection position between the end cover 4 and the housing 3 during use.

[0036] After the worker completes the installation of the housing 3, the worker winds the welding wire to be used into the storage slot 22 on the side of the mounting sleeve 17, and one end of the welding wire is connected to the welding gun 19 through the connecting block 21 on the side of the fixed sleeve 13 and the hydraulic telescopic seat 18. During use, the worker threads one of the internal threaded blocks 16 onto the mounting shaft 8 and adjusts the position of the internal threaded block 16 so that it moves to a position inside the welding piece 34, offset from the mounting plate 1. The worker can replace the welding gun 19 installed on the hydraulic telescopic seat 18 with a flame gun as needed, and disconnect the welding wire from the connecting block 21.

[0037] The operator can first install the flame gun on the hydraulic telescopic base 18 and thread the mounting sleeve 17 onto the mounting shaft 8. By rotating the mounting sleeve 17, the fixing sleeve 13 is moved into the interior of the housing 3, and the mounting sleeve 17 abuts against the side of the internally threaded block 16 pre-installed inside the housing 3. The internally threaded block 16 is then installed on the outer wall of the mounting shaft 8 again, so that the two internally threaded blocks 16 located inside the housing 3 clamp the mounting sleeve 17. The first electric slider 11 slides inside the first slide groove 10, and drives the end of the protective plate 6 near the mounting plate 1 to move upward until the end of the protective plate 6 near the mounting plate 1 is flush with the height of the mounting shaft 8. While the protective plate 6 moves, the moving plate 27 on it slides within the fixing hole 28. The operator rotates the movable plate 27 and pulls it away from the mounting plate 1 until the side of the clamping block 35 on the movable plate 27 abuts against the end of the housing 3 away from the end cover 4. The two support rods 33 located inside the fixing hole 28 provide good guidance for the movement of the movable plate 27 and also support the protective plate 6 and the movable plate 27, making the movable plate 27 more stable during use. During use, the elastic tension of the spring 32 drives the clamping block 35 to push the housing 3 towards the mounting plate 1, so that the clamping block 35 and the fixing shell 12 cooperate to clamp and fix the housing 3, the welding piece 34 and the end cover 4.

[0038] When the position of the flame gun and the welding piece 34 deviates, the operator can push the fixed shell 12 to rotate on the outer wall of the mounting shaft 8, thereby rotating and moving the end cover 4, the welding piece 34, and the housing 3 until the flame gun is positioned inside the welding piece 34 and corresponds to it. After adjusting the position of the flame gun and the welding piece 34, the operator rotates the internal thread block 16 on the outer wall of the mounting shaft 8 near the mounting plate 1 to fix the position of the fixed shell 12. The operator can then use the hydraulic telescopic seat 18 to move the flame gun closer to the welding piece 34 and heat it, causing it to melt. This melting of the welding piece 34 achieves the effect of welding the housing 3 and the end cover 4 face to face. In use, the operator can use the second electric slider 24 to rotate the fixed sleeve 13 and several flame guns, allowing the flame guns to evenly heat different positions of the welding piece 34, improving the welding efficiency of the housing 3 and the end cover 4.

[0039] After the worker melts the welding of the end cover 4 and the housing 3 using the welding piece 34, the worker can disassemble the internal threaded block 16 on the outer wall of the mounting shaft 8, located on the side of the mounting sleeve 17 away from the mounting plate 1, and move the fixing sleeve 13 and the mounting sleeve 17 away from the mounting plate 1. During use, the worker can replace the flame gun on the hydraulic telescopic seat 18 with a welding gun 19, and connect the wound welding wire to the welding gun 19 via the connecting block 21 and the hydraulic telescopic seat 18. The worker then moves the fixing sleeve 13 and the movable internal threaded block 16 back into the housing 3, so that the side of the mounting sleeve 17 abuts against the stationary internal threaded block 16 located inside the housing 3. During use, the worker no longer needs to adjust the position of the fixing sleeve 13. When welding the edges of the opposite surfaces of the housing 3 and end cover 4 near the inner wall, the hydraulic telescopic base 18 moves the welding gun 19 to the opposite surface of the housing 3 and end cover 4, and the second electric slider 24 rotates the fixed sleeve 13. During use, the welding gun 19 pulls the welding wire to rotate the connection point between the housing 3 and end cover 4. As the fixed sleeve 13 rotates, the welding wire wound inside the storage groove 22 is pulled through the connecting block 21, allowing the welding gun 19 to quickly weld the connection point between the housing 3 and end cover 4. During use, the operator can replace the welding gun 19 or the flame gun on the hydraulic telescopic base 18 as needed. Because several hydraulic telescopic bases 18 are installed on the outer wall of the fixed sleeve 13, the operator can also install both the welding gun 19 and the flame gun simultaneously. This eliminates the need for manual replacement of the welding gun 19 or the flame gun, improving the welding efficiency of the housing 3 and end cover 4.

[0040] When workers weld the housing 3 and end cover 4 using a blowtorch and welding torch 19, the air purifier 20 located inside the mounting hole 26 at the end of the mounting shaft 8 away from the mounting plate 1 can absorb and purify the gases generated during welding through several air inlets 25. The purified air is then discharged to the outside through the end of the mounting shaft 8 away from the mounting plate 1. This prevents harmful gases generated during welding from affecting the health of surrounding workers. At the same time, when the blowtorch is used to weld the housing 3 and end cover 4, the heat emitted by the welding piece 34 as it melts and then solidifies is absorbed, which can quickly cool the inside of the housing 3 and prevent the high temperature generated by the blowtorch from affecting the inner walls of the housing 3 and end cover 4. This provides good protection for the housing 3 and end cover 4 during use.

[0041] After the workers finish welding the housing 3 and the end cover 4, the first electric slider 11 moves the protective plate 6 down to the end near the mounting plate 1. The workers rotate the moving plate 27 and move the clamping block 35 on the moving plate 27 into the slot 31. The ends of the moving plate 27 and the protective plate 6 away from the first electric slider 11 move into the placement slot 7. The slot 31 can effectively fix the moving plate 27 and the protective plate 6 in place by using the clamping block 35.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
