Description

Technical Field

[0001] This invention belongs to the field of welding equipment, and particularly relates to a welding device for motor housings. Background Technology

[0002] The motor housing is the outer casing used to protect the internal components and structure of the motor. The motor housing is usually made of metal, plastic or other sturdy and durable materials to withstand the vibration, temperature and pressure during motor operation. The main functions of the motor housing are to protect the internal components of the motor, promote the dissipation of heat from the motor, and provide structural support for the motor.

[0003] In the motor manufacturing process, in order to better dissipate heat, several heat sinks are usually welded to the outside of the motor casing to dissipate the heat of the motor.

[0004] Traditionally, this welding process is usually done manually. During welding, the worker holds the heat sink with one hand and operates the welding gun with the other to weld the heat sink to the motor housing. However, because the heat sink is narrow and the distance between adjacent heat sinks is small, the worker can only hold the edge of the heat sink behind the one in front of him. When the worker's hand shakes, the heat sink will deviate in position, which will reduce the welding quality of the heat sink and also affect the heat dissipation effect of the motor. Summary of the Invention

[0011] The second socket is equipped with a second clamping mechanism, which is used to fix the heat sink in the second slot.

[0012] Further technical solution: The second clamping mechanism includes an arc-shaped slide bar slidably mounted on the second socket. The axis of the arc-shaped slide bar coincides with the axis of the second socket. An installation groove is provided on the side of each second slot.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. This invention, by setting up a feeding mechanism, allows multiple heat sinks to be installed onto the feeding mechanism first during heat sink installation. The feeding mechanism then places the heat sinks onto the surface of the motor housing. Finally, a welding mechanism is used to weld all the heat sinks. During this process, workers only need to install the heat sinks and do not need to manually weld them, which greatly improves welding efficiency and welding quality. By arranging all the heat sinks onto the motor housing through the feeding mechanism, the position of the heat sinks is more precise, thereby improving the heat dissipation effect of the motor.

[0018] 2. In this invention, during welding, all the heat sinks on the second socket are first spot-welded to the motor housing, then the feeding mechanism is removed, and finally the heat sinks are continuously welded. This avoids the feeding mechanism affecting the welding of the heat sinks. After spot-welding one heat sink, when the motor housing is rotated, the motor housing will drive the second socket to rotate through the heat sink, so that the second socket drives all the heat sinks on it to rotate synchronously. This ensures that all the heat sinks maintain their relative positions, avoids misalignment of the heat sinks, and improves the welding quality of the heat sinks.

[0019] 3. In this invention, by setting an auxiliary component, while the welding mechanism is welding the heat sink on the motor housing, the operator can first insert a group of multiple heat sinks into the second slot, then transfer the heat sinks to the second socket, and then send the heat sinks to the motor housing through the second socket, making the heat sink loading operation more convenient and reducing the workload of the operator.

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0028] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0029] like Figures 1-6 As shown, a motor housing welding device provided by the present invention includes a processing table 1, a support mechanism 2 installed below the processing table 1, a square hole adapted to the output end of the support mechanism 2 on the processing table 1, the output end of the support mechanism 2 passing through the square hole and extending above the processing table 1, the support mechanism 2 being used to support the motor housing 3, a first clamping mechanism 4 being installed on the processing table 1, the first clamping mechanism 4 being used to clamp and fix the motor housing 3 and being able to drive the motor housing 3 to rotate, a welding mechanism 5 and a feeding mechanism 6 being installed on the processing table 1, the feeding mechanism 6 being used to fix the heat sink 8 to the motor housing 3, and the welding mechanism 5 being used to weld the heat sink 8 to the motor housing 3.

[0030] In use, the motor housing 3 is first placed on the support mechanism 2, and then the first clamping mechanism 4 is used to clamp and fix the motor housing 3. The output end of the support mechanism 2 is lowered and separated from the motor housing 3. Then, a group of multiple heat sinks 8 are installed on the output end of the feeding mechanism 6. The feeding mechanism 6 places the heat sinks 8 onto the surface of the motor housing 3. Then, the welding mechanism 5 is used to spot weld all the heat sinks 8 to fix them to the motor housing 3. The feeding mechanism 6 is then removed to avoid interfering with the welding mechanism 5's welding of the heat sinks 8. Finally, the welding mechanism 5 welds all the heat sinks 8 to the motor housing 3. During the welding process, the operator can install another set of heat sinks 8 onto the feeding mechanism 6. After welding, the first clamping mechanism 4 drives the motor housing 3 to rotate at a certain angle, and then the feeding mechanism 6 places the heat sinks 8 onto the motor housing 3. By repeating the above steps, multiple sets of heat sinks 8 can be welded onto the motor housing 3. In this process, the operator only needs to install the heat sinks 8 and does not need to weld manually, making welding more convenient and greatly improving welding efficiency and quality. By arranging all the heat sinks 8 onto the motor housing 3 through the feeding mechanism 6, the position of the heat sinks 8 is more accurate, thereby improving the heat dissipation effect of the motor.

[0031] The present invention provides a welding device for a motor housing 3. In this embodiment, the support mechanism 2 includes a first telescopic rod 21, which is installed below the processing table 1. A support base 22 is fixedly installed on the movable end of the first telescopic rod 21. The top of the support base 22 is provided with an arc groove that is adapted to the motor housing 3.

[0032] When installing the motor housing 3, first raise the support base 22 above the processing table 1, then place the motor housing 3 into the arc groove, fix the motor housing 3 by the first clamping mechanism 4, and then the first telescopic rod 21 drives the support base 22 to descend, so as to avoid the support base 22 affecting the rotation of the motor housing 3.

[0033] The present invention provides a welding device for a motor housing 3. In this embodiment, the first clamping mechanism 4 includes a push cylinder 44 fixedly installed on a processing table 1. A sliding seat 43 is fixedly installed on the movable end of the push cylinder 44. The sliding seat 43 is slidably installed on the processing table 1. A first servo motor 42 is fixedly installed on the sliding seat 43. An inner clamping assembly 41 is fixedly installed on the output shaft of the first servo motor 42. A vertical plate 45 is also fixedly installed on the processing table 1. The inner clamping assembly 41 is rotatably installed on the side of the vertical plate 45 near the first servo motor 42. The two inner clamping assemblies 41 are respectively located on both sides of the support mechanism 2.

[0034] Specifically, when installing the motor housing 3, the two inner clamping components 41 are first separated, and then the motor housing 3 is placed on the support base 22 through the gap between the two inner clamping components 41. Then, the push cylinder 44 drives the sliding seat 43 to move towards the upright plate 45, so that the ends of the two inner clamping components 41 abut against each other. At the same time, the two inner clamping components 41 clamp and fix the motor housing 3 from the inside.

[0035] The present invention provides a welding device for a motor housing 3. In this embodiment, the inner clamping assembly 41 includes a mounting plate 411. A mounting cylinder 412 is fixedly mounted on the side of the mounting plate 411. A plurality of mounting tubes 416 are evenly connected to the side of the mounting cylinder 412. A clamping rod 415 is slidably mounted inside each mounting tube 416. An arc-shaped clamping block 414 is fixedly connected to one end of the clamping rod 415 extending out of the mounting tube 416. A tension spring connects the clamping rod 415 and the mounting tube 416. 417. One end of the clamping rod 415 is fixedly connected to an abutment rod 418. One end of the abutment rod 418 extends into the interior of the mounting cylinder 412. An extrusion column 419 is slidably installed inside the mounting cylinder 412. A first compression spring 413 is connected between the extrusion column 419 and the mounting plate 411. One end of the extrusion column 419 near the mounting plate 411 is provided with a conical surface. The ends of the plurality of abutment rods 418 abut against the conical surface. The other end of the extrusion column 419 extends out of the mounting cylinder 412.

[0036] Specifically, in this embodiment, there are three mounting tubes 416, which are evenly distributed around the axis of the mounting cylinder 412, and the end of the arc-shaped clamping block 414 is an arc surface adapted to the inner wall diameter of the motor housing 3.

[0037] In this embodiment, the upright plate 45 is installed on the left side of the support mechanism 2, the mounting plate 411 on the left side is rotatably mounted on the upright plate 45, and the mounting plate 411 on the right side is fixedly mounted on the output shaft of the first servo motor 42.

[0038] Initially, under the action of the tension spring 417, the clamping rods 415 retract into the mounting tube 416. When installing the motor housing 3, one end of the motor housing 3 is first fitted onto the mounting cylinder 412 on the left side, and the motor housing 3 is placed on the support seat 22. Then, the push cylinder 44 drives the sliding seat 43 and the first servo motor 42 to move. When the ends of the extrusion columns 419 on the two inner clamping components 41 come into contact, they will press against each other, causing the extrusion columns 419 to gradually retract into the mounting cylinder 412. Then, the extrusion columns 419 press against the abutment rod 418 through the conical surface. The abutment rod 418 drives the clamping rods 415 and the arc-shaped clamping blocks 414 to move outward. Multiple arc-shaped clamping blocks 414 clamp and fix the motor housing 3 from the inside.

[0039] In addition, since the elastic coefficients of the two first compression springs 413 are the same, the movement distance of the two extrusion columns 419 is the same at the same time, which makes the clamping force of the two inner clamping components 41 on the motor housing 3 the same. This can avoid the situation where the two ends of the motor housing 3 are offset due to the different clamping forces at both ends of the motor housing 3, which would lead to a decrease in the welding quality of the heat sink 8.

[0040] The present invention provides a welding device for a motor housing 3. In this embodiment, the feeding mechanism 6 includes a second mounting frame 63 fixedly mounted on a processing table 1. A second linear module 61 is fixedly mounted on the second mounting frame 63. A second telescopic rod 62 is fixedly mounted on the output end of the second linear module 61. A second servo motor 64 is fixedly mounted on the movable end of the second telescopic rod 62. An arc-shaped slide rail 66 is fixedly mounted on the output shaft of the second servo motor 64 through a second eccentric plate 65. A slider 67 is slidably mounted inside the arc-shaped slide rail 66. A bending spring 610 is connected between both sides of the slider 67 and the arc-shaped slide rail 66. A second socket 68 is fixedly connected to one end of the slider 67 extending out of the arc-shaped slide rail 66. A plurality of second slots 74 are equally angled at the bottom of the second socket 68. The second slots 74 are used to insert heat sinks 8.

[0041] A second clamping mechanism 69 is installed on the second socket 68, which is used to fix the heat sink 8 in the second slot 74.

[0042] Specifically, the staff inserts a set of heat sinks 8 into the second slot 74, and then clamps and fixes all the heat sinks 8 through the second clamping mechanism 69. Then, the second linear module 61 drives the second telescopic rod 62 and the heat sinks 8 to move above the motor housing 3. Then, the second telescopic rod 62 drives the heat sinks 8 to descend, so that all the heat sinks 8 are in contact with the surface of the motor housing 3. At this time, the welding mechanism 5 can be used to spot weld one heat sink 8. Then, the first servo motor 42 drives the motor housing 3 to rotate the angle of one heat sink 8 so that the other unwelded heat sink 8 faces upward. Then, the welding mechanism 5 is used to spot weld again. Repeat the above steps to spot weld all the heat sinks 8 in a set.

[0043] It is worth mentioning that after spot welding a heat sink 8 and rotating the motor housing 3, the motor housing 3 will drive the second socket 68 to rotate through the heat sink 8. The second socket 68 will rotate along the arc-shaped slide rail 66 through the slider 67, so that the second socket 68 can drive all the heat sinks 8 on it to rotate synchronously, thus keeping all the heat sinks 8 in a constant relative position, avoiding misalignment of the heat sinks 8 and improving the welding quality of the heat sinks 8.

[0044] After all the heat sinks 8 have been spot-welded, the second clamping mechanism 69 releases the heat sinks 8 from its fixation. Then, the second telescopic rod 62 lifts the second socket 68. The second linear module 61 moves the second telescopic rod 62 away from the motor housing 3. At the same time, the second servo motor 64 rotates the second eccentric plate 65 180°, thereby rotating the second socket 68 outside the processing table 1. While the welding mechanism 5 is welding all the heat sinks 8 on the motor housing 3, the operator can install the next set of heat sinks 8 onto the second socket 68 for the next welding of the heat sinks 8.

[0045] The present invention provides a welding device for a motor housing 3. In this embodiment, the second clamping mechanism 69 includes an arc-shaped slide bar 691 slidably mounted on a second socket 68. The axis of the arc-shaped slide bar 691 coincides with the axis of the second socket 68. An installation groove is provided on the side of each second slot 74. One end of the installation groove is connected to the arc-shaped slide bar 691. A clamping plate 697 and a push plate 695 are slidably mounted inside the installation groove. One end of the push plate 695 is fixedly connected to the arc-shaped slide bar 691. A second compression spring 696 is connected between the clamping plate 697 and the push plate 695. Initially, the side of the clamping plate 697 is flush with the side wall of the second slot 74 to prevent the clamping plate 697 from blocking the insertion of the heat sink 8.

[0046] To drive the arc-shaped slide bar 691 to move, the second clamping mechanism 69 also includes a clamping cylinder 694 fixedly installed on the second socket 68. A fixing block 693 is fixedly installed on the movable end of the clamping cylinder 694. A connecting plate 692 is rotatably installed on the side of the fixing block 693. The other end of the connecting plate 692 is rotatably connected to the end of the arc-shaped slide bar 691 through a pin.

[0047] Specifically, after the heat sink 8 is inserted into the second slot 74 on the second socket 68, the clamping cylinder 694 drives the fixing block 693 to retract. The fixing block 693 drives the arc-shaped slide bar 691 to move through the connecting plate 692. The arc-shaped slide bar 691 drives all the push plates 695 to move. The push plates 695 squeeze the clamping plate 697 through the second compression spring 696. Under the elastic force of the second compression spring 696, the clamping plate 697 clamps and fixes the heat sink 8.

[0048] The present invention provides a welding device for a motor housing 3. When installing heat sinks 8, the installation is inconvenient for workers because the second slots 74 on the second socket 68 face downwards and there are many heat sinks 8 to be installed. Therefore, in this embodiment, an auxiliary component 7 is also installed on the side of the processing table 1. The auxiliary component 7 includes a mounting table 71. A first socket 73 is fixedly installed on the top of the mounting table 71. A plurality of second slots 74 are opened at equal angles on the first socket 73. The second slots 74 are used to insert heat sinks 8. The number and position of the second slots 74 are adapted to the number and position of the second slots 74. An alignment plate 72 is also slidably installed on the mounting table 71.

[0049] Specifically, while the welding mechanism 5 is welding the heat sinks 8 on the motor housing 3, the operator can first insert a group of multiple heat sinks 8 into the second slot 74, then use the alignment plate 72 to press all the heat sinks 8 flat, and then push the alignment plate 72 to the end of the mounting platform 71 to avoid affecting the transfer of the heat sinks 8. After all the heat sinks 8 on the motor housing 3 are spot welded, the second socket 68 is moved above the first socket 73, and then the second telescopic rod 62 drives the second socket 68 to descend, so that the second socket 68 covers the first socket 73, and all the heat sinks 8 on the first socket 73 are inserted into the second slot 74. Then the second clamping mechanism 69 is used to fix the heat sinks 8. Finally, the second telescopic rod 62 can lift the heat sinks 8 through the second socket 68 and send them above the motor housing 3. Compared with directly installing the heat sinks 8 onto the second socket 68, in this embodiment, the heat sinks 8 are first installed onto the auxiliary component 7, and then the heat sinks 8 are transferred to the second socket 68, making the loading operation of the heat sinks 8 more convenient.

[0050] The present invention provides a welding device for a motor housing 3. In this embodiment, the welding mechanism 5 includes a first mounting frame 51 fixedly mounted on a processing table 1. A first linear module 52 is fixedly mounted on the first mounting frame 51. A third telescopic rod 53 is fixedly mounted on the output end of the first linear module 52. A third servo motor 54 is fixedly mounted on the movable end of the third telescopic rod 53. A welding gun 56 is mounted on the output shaft of the third servo motor 54 through a first eccentric plate 55. One end of the welding gun 56 is connected to the welding machine body.

[0051] In use, the welding gun 56 is first driven to the end of the heat sink 8 by the first linear module 52, and then the end of the heat sink 8 is spot welded by the welding gun 56. After all the heat sinks 8 are spot welded, the feeding mechanism 6 is removed, and then the welding gun 56 is used to continuously weld along the length of the heat sink 8. After welding to the other end of the heat sink 8, the first eccentric plate 55 can be rotated 180° by the third servo motor 54 to weld the end of the heat sink 8. After welding one heat sink 8, the motor housing 3 is rotated by the first servo motor 42 to rotate another heat sink 8 to the bottom of the welding gun 56, and then the other heat sink 8 can be welded. The above operation is repeated until all the heat sinks 8 are welded to the motor housing 3.

[0052] Working principle:

[0053] First, a set of heat sinks 8 are installed on the first socket 73. Then, the motor housing 3 is placed on the support base 22. Next, the propulsion cylinder 44 is used to drive the inner clamping assembly 41 to move, so that the two inner clamping assemblies 41 clamp the motor housing 3 from the inside. The first telescopic rod 21 drives the support base 22 to fall. Then, the feeding mechanism 6 picks up all the heat sinks 8 on the first socket 73 and drives the heat sinks 8 to move to the surface of the motor housing 3. Then, the welding mechanism 5 is used to spot weld the ends of all the heat sinks 8. Then, the feeding mechanism 6 is moved away, and then the welding mechanism 5 is used to continuously weld all the heat sinks 8.

[0054] During the welding process of heat sink 8, the worker can install the next set of heat sink 8 onto the first socket 73 and pick it up through the feeding mechanism 6. After the welding mechanism 5 has finished welding all the heat sinks 8 on the motor housing 3, the first servo motor 42 rotates the motor housing 3 by a certain angle, and then the feeding mechanism 6 places the next set of heat sinks 8 onto the motor housing 3. Welding of the heat sinks 8 can continue until the welding operation of the motor housing 3 is completed.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0056] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
