Description

Technical Field

[0001] This invention relates to the field of rotor processing technology, and in particular to a spot welding device for processing intelligent motor rotors. Background Technology

[0002] Intelligent motor rotors are one of the key processing components in modern welding and cutting equipment. Their processing typically uses technologies such as automatic and semi-automatic electric arc welding and plasma arc welding. These devices achieve efficient and precise metal cutting and welding through intelligent control systems, improving production efficiency and welding quality. Intelligent casting islands are production units that integrate automated casting technology. By utilizing the high performance of intelligent motor rotors, the casting process is optimized, improving product consistency and reliability. Existing motor rotors are cylindrical, and they are prone to slippage during welding, causing them to deviate from the welding equipment's working range. This requires additional time to reposition the motor rotor, thus interfering with the welding equipment's production progress. To address this, we propose an intelligent spot welding device for motor rotor processing. Summary of the Invention

Motor A is fixed to the bottom of the square-round plate of gear B. The output end of the top of motor A is fixed to the center of the bottom of gear B. Gear A has three pads at its bottom. The outer walls of the top of the three pads are in contact with the outer walls of the bottom of gear A. The sides of the three pads that are far apart from each other are fixed to the inner wall of the cylinder.

[0010] The adjustment mechanism includes an outer box, with a cover plate fixed to the bottom of the outer box. The bottom of the cover plate is fixed to the top of the base. A limit post is fixed at the center of the top of the cover plate. A shaped rotating wheel is rotatably connected to the top of the limit post. The shaped rotating wheel consists of two flat plates. Several cylinders are fixed on the side of the two shaped rotating wheel plates that are close to each other. Flat surfaces are provided on the left and right sides of the outer wall of the bottom shaped rotating wheel plate. Curved surfaces are provided on the front and back sides of the outer wall of the bottom shaped rotating wheel plate. A shaped rotating plate is provided on the left side of the shaped rotating wheel. The left outer wall of the shaped rotating plate is in contact with the flat surface on the left side of the shaped rotating wheel. The shaped rotating plate consists of two semicircular plates. The semicircular plate of the top shaped rotating plate is larger than the semicircular plate of the bottom shaped rotating plate.

[0011] The right outer wall of the irregularly shaped rotating plate semicircular plate located at the bottom is fixed with several cylinders. The cylinders of the irregularly shaped rotating plate extend into the cylinders of the irregularly shaped rotating wheel. A cavity is opened on the left side of the outer box. A cylindrical pin is fixed at the center of the left side of the irregularly shaped rotating plate. The cylindrical pin of the irregularly shaped rotating plate extends into the cavity of the outer box. Two gears C are arranged in a vertical array in the cavity of the outer box. The two gears C mesh with each other. The bottom gear C is fixed on the pin shaft of the irregularly shaped rotating plate. The right side of the bottom gear C extends into the interior of the outer box. A motor C is arranged on the right side of the bottom gear C. The motor C is fixed on the left inner wall of the outer box. The output end of the motor C is fixed on the right outer wall of the bottom gear C.

[0012] The auxiliary mechanism includes a protective shell, with a ratchet located at the center inside the protective shell. The top and bottom of the ratchet extend outward through the top and bottom of the protective shell, respectively. The top and bottom of the ratchet are rotatably connected to the top and bottom of the protective shell, respectively. Four pins are located on the outside of the ratchet, and the four pins on the outside of the ratchet are fixed to the inner wall of the protective shell. Pads are rotatably connected to the outside of the four pins on the protective shell.

[0013] The four pawls extend outward from the side closest to each other, and the side closest to each other engages with the outer wall of the ratchet. The outer wall of the protective shell has several slots. The side furthest from each other of the four pawls is fixed with a lever. The four levers pass through the four slots and extend outward. The outer walls of the four pawls are fixed with springs. Taking the pawl located at the center of the front as an example, the pawl is flexibly constrained to the inner wall of the protective shell by the spring.

[0014] The beneficial effects of this invention are: (1) The present invention is provided with a positioning mechanism. When the motor A is started, its output end drives the gear B to rotate. While the gear B rotates, it drives the gear A to rotate through meshing connection. The gear A drives several arc grooves to rotate. The arc grooves drive the L-shaped slide plate to move along the cross-shaped slide through the pin shaft. When several L-shaped slide plates approach each other along the cross-shaped slide, they will clamp the outer wall of the rotor through the clamp plate installed at the top, positioning the rotor at the top center of the cylinder. This reduces the probability of the rotor sliding when the welding machine is working, reduces the time spent redeploying the rotor, and thus ensures the production progress of the welding machine for processing the motor rotor.

[0015] (2) The present invention is provided with an adjustment mechanism. When the motor C is started, its output end drives the pin shaft of the irregular plate to rotate through two gears C. The irregular plate rotates on its own and at the same time, the irregular wheel is driven by the cylinder to rotate. When the plane of the irregular wheel contacts the outer wall of the right side of the irregular plate, it will be blocked, thus restricting the rotation of the irregular wheel. In this way, the rotation of the irregular wheel can drive the positioning mechanism installed on the top to rotate, moving the right side area of ​​the rotor to the left side, so that the rotor can be welded more fully, reducing the risk of welding defects in the rotor, thereby improving the production quality of rotor welding.

[0016] (3) The present invention is provided with an auxiliary mechanism. When the ratchet at the center of the protective shell is rotated, the ratchet rotates. When the ratchet rotates, it pushes the pawl to rotate through the inclined plane, causing the pawl to deflect. Then, the deflection of the pawl pulls the spring. When the contact between the pawl and the ratchet ends, the pawl will be reset by the spring rebound and re-engage with the ratchet. In this way, the rotation direction of the positioning mechanism and the adjustment mechanism can be restricted, reducing the probability of the positioning mechanism and the adjustment mechanism reversing, reducing the probability of repeated welding in local areas of the rotor, thereby improving the processing quality of the rotor.

[0019] Please see Figures 1 to 8 The image shown is an embodiment of the present invention.

[0020] A spot welding device for processing intelligent motor rotors includes a base 11, a positioning mechanism 12, an adjustment mechanism 13, and an auxiliary mechanism 14. The positioning mechanism 12 is located at the top of the base 11, the adjustment mechanism 13 is located at the bottom of the positioning mechanism 12, and the auxiliary mechanism 14 is located on the side where the top of the adjustment mechanism 13 and the bottom of the positioning mechanism 12 are close to each other. The positioning mechanism 12 is located at the top, the auxiliary mechanism 14 is located in the middle, and the adjustment mechanism 13 is located at the bottom. The positioning mechanism 12 includes a cylinder 121, a welding machine 122 is provided on the left side of the cylinder 121, a rotor is placed at the center of the top outer wall of the cylinder 121, and a drive group is provided at the center of the top inner wall of the cylinder 121; wherein the welding machine 122 is used to weld the wires of the rotor.

[0021] The motor A128 is started, causing its output end to drive the gear B127 to rotate. While the gear B127 rotates, it also drives the gear A125 to rotate through meshing. The gear A125 drives several arc grooves 126 to rotate, and the arc grooves 126 drive the L-shaped slide plate 1232 to move along the cross-shaped slide groove 1231 through the pin shaft. When several cover plate L-shaped slide plates 1232 approach each other along the cross-shaped slide groove 1231, they will clamp the outer wall of the rotor through the clamping plate 124 installed at the top, positioning the rotor at the top center of the cylinder 121. This reduces the probability of the rotor sliding when the welding machine 122 is working, reduces the time spent redeploying the rotor, and thus ensures the production progress of the welding machine 122 in processing the motor rotor.

[0022] The drive assembly includes a star-shaped slide 1231, which is fixed at the center of the inner top wall of the welding machine 122. Several L-shaped slide plates 1232 are slidably connected to the bottom of the star-shaped slide 1231. The sides of the several L-shaped slide plates 1232 that are far apart from each other pass through the cylinder 121 and extend outward. The several L-shaped slide plates 1232 are slidably connected to the cylinder 121. The tops of the several L-shaped slide plates 1232 extend toward the center of the top of the cylinder 121. Clamping plates 124 are fixed to the sides of the tops of the several L-shaped slide plates 1232 that are close to each other.

[0023] Several clamping plates 124 are arranged in the form of fan-shaped protrusions. Several grooves are opened on the side of the clamping plates 124 that are close to each other. The clamping plates 124 are arranged in a circumferential array with the cylinder 121 as the center. The side of the clamping plates 124 that are close to each other is respectively attached to the outer wall of the rotor. The bottom side of the several L-shaped sliding plates 1232 is respectively fixed with cylindrical pins. A round rod is fixed at the bottom center of the cross-shaped sliding groove 1231. A gear A125 is rotatably connected to the outside of the round rod of the cross-shaped sliding groove 1231.

[0024] The top of gear A125 has several arc grooves 126, which are arranged in a circular array around gear A125. The cylindrical pins of several L-shaped slide plates 1232 extend into the arc grooves 126 respectively, and the cylindrical pins of the L-shaped slide plates 1232 are slidably connected to the arc grooves 126 respectively. The bottom of the round rod of the L-shaped slide plate 1232 is fixed to the bottom inner wall of the cylinder 121. The top dimension of the round rod of the L-shaped slide plate 1232 is smaller than the bottom dimension. Gear B127 is meshed with the outer right side of gear A125.

[0025] Gear B127 is smaller than gear A125. Gear B127 has a square-round plate at its bottom. The right side of the square-round plate at the bottom of gear B127 is fixed to the inner wall of cylinder 121. The center of the bottom of gear B127 is rotatably connected to the square-round plate. Motor A128 is fixed to the bottom of the square-round plate of gear B127. The output end of the top of motor A128 is fixed to the center of the bottom of gear B127. Gear A125 has three pads 129 at its bottom. The outer top walls of the three pads 129 are in contact with the outer bottom walls of gear A125. The sides of the three pads 129 that are far apart from each other are fixed to the inner wall of cylinder 121.

[0026] The adjustment mechanism 13 includes an outer box 131, a cover plate 132 fixed to the bottom of the outer box 131, the bottom of the cover plate 132 fixed to the top of the base 11, a limit post 133 fixed at the center of the top of the cover plate 132, and an irregularly shaped rotating wheel 134 rotatably connected to the top of the limit post 133. The irregularly shaped rotating wheel 134 is composed of two flat plates, and several cylinders are fixed on the side of the two irregularly shaped rotating wheel 134 plates that are close to each other. The left and right sides of the outer wall of the irregularly shaped rotating wheel 134 plate at the bottom are respectively provided with flat surfaces, and the front and back sides of the outer wall of the irregularly shaped rotating wheel 134 plate at the bottom are respectively provided with curved surfaces. An irregularly shaped rotating plate 135 is provided on the left side of the irregularly shaped rotating wheel 134. The left outer wall of the irregularly shaped rotating plate 135 is in contact with the flat surface on the left side of the irregularly shaped rotating wheel 134. The irregularly shaped rotating plate 135 is composed of two semicircular plates, and the semicircular plate at the top of the irregularly shaped rotating plate 135 is larger than the semicircular plate at the bottom.

[0027] The motor C137 is started, and its output end drives the pin shaft of the irregular rotating plate 135 to rotate through two gears C136. The irregular rotating plate 135 rotates on its own axis and simultaneously drives the irregular rotating wheel 134 through the cylinder, causing the irregular rotating wheel 134 to rotate. When the plane of the irregular rotating wheel 134 contacts the outer wall of the right side of the irregular rotating plate 135, it will be obstructed, thus restricting the rotation of the irregular rotating wheel 134. In this way, the rotation of the irregular rotating wheel 134 can drive the positioning mechanism 12 installed on the top to rotate, moving the right side area of ​​the rotor to the left side, so that the rotor can be fully welded, reducing the risk of welding defects in the rotor, thereby improving the production quality of rotor welding.

[0028] Several cylinders are fixed to the right outer wall of the irregular rotating plate 135 at the bottom. The cylinders of the irregular rotating plate 135 extend into the cylinder of the irregular rotating wheel 134. A cavity is opened on the left side of the outer box 131. A cylindrical pin is fixed at the center of the left side of the irregular rotating plate 135. The cylindrical pin of the irregular rotating plate 135 extends into the cavity of the outer box 131. Two gears C136 are arranged in a vertical array and mesh with each other in the cavity of the outer box 131. The bottom gear C136 is fixed on the pin shaft of the irregular rotating plate 135. The right side of the bottom gear C136 extends into the interior of the outer box 131. A motor C137 is arranged on the right side of the bottom gear C136. The motor C137 is fixed on the left inner wall of the outer box 131. The output end of the motor C137 is fixed on the right outer wall of the bottom gear C136.

[0029] The auxiliary mechanism 14 includes a protective shell 141. A ratchet 142 is provided at the center inside the protective shell 141. The top and bottom of the ratchet 142 pass through the top and bottom of the protective shell 141 and extend outward. The top and bottom of the ratchet 142 are rotatably connected to the top and bottom of the protective shell 141, respectively. Four pins are provided on the outside of the ratchet 142. The four pins on the outside of the ratchet 142 are fixed to the inner wall of the protective shell 141, and pawls 143 are rotatably connected to the outside of the four pins on the protective shell 141.

[0030] Rotating the ratchet 142 located at the center of the protective housing 141 causes it to rotate. This rotation pushes the pawl 143 through the inclined plane, causing it to deflect. The deflection of the pawl pulls the spring 146. Once the contact between the pawl 143 and the ratchet 142 ends, the pawl 143 is reset by the spring 146 and re-engages with the ratchet 142. This restricts the rotation direction of the positioning mechanism 12 and the adjusting mechanism 13, reducing the probability of reverse rotation and minimizing the chance of repeated welding in localized areas of the rotor, thereby improving the rotor's processing quality. The four pawls 143 extend outward from the side of the ratchet 142, and the side of the four pawls 143 that are close to each other engages with the outer wall of the ratchet 142. The outer wall of the protective shell 141 has several slots 144. The side of the four pawls 143 that are far apart from each other is fixed with levers 145. The four levers 145 pass through the four slots 144 and extend outward. The outer side walls of the four pawls 143 are fixed with springs 146. Taking the pawl 143 located at the center of the front as an example, the pawl 143 is flexibly constrained to the inner wall of the protective shell 141 by the springs 146.

[0031] In use, the rotor is placed at the center of the top of the cylinder 121, and then the motor A128 is started, which drives the gear B127 to rotate. The gear B127 then drives the gear A125 to rotate through meshing. The rotation of the gear A125 causes several arc grooves 126 to rotate, which in turn causes the arc grooves 126 to drive the L-shaped slide plates 1232 to move along the herringbone slide groove 1231 via pins. When several cover plate L-shaped slide plates 1232 approach each other along the herringbone slide groove 1231, they will pass through the top. The clamping plate 124 clamps the outer wall of the rotor, positioning it at the top center of the cylinder 121. As several L-shaped sliding plates 1232 move away from each other along the herringbone groove 1231, the reverse occurs. Then, the welding machine 122 is started to weld the left side of the rotor. Subsequently, the motor C137 is started, driving the bottom gear C136 to rotate. Through the meshing of two gears C136, the gears C136 drive the pin shaft of the shaped rotating plate 135 to rotate, allowing the shaped rotating plate to rotate. As plate 135 rotates, it simultaneously actuates the irregularly shaped rotating wheel 134 via the cylinder. The irregularly shaped rotating wheel 134 rotates when actuated. When the planar area of ​​the irregularly shaped rotating wheel 134 contacts the right side of the irregularly shaped rotating plate 135, its rotation is obstructed and it cannot continue rotating. The right side of the rotor is then moved to the left side, placing it within the processing range of the welding machine 122. The welding machine 122 is then started and welding is performed. The process reverses when the irregularly shaped rotating plate 135 ceases contact with the plane of the irregularly shaped rotating wheel 134. When the 34 rotates, it will drive the ratchet 142 installed at the top center to rotate. When the ratchet 142 rotates, it will push the pawl 143 to rotate through the inclined plane, causing the pawl 143 to deflect. Then, the deflection of the pawl 143 will pull the spring 146. When the contact between the pawl 143 and the ratchet 142 ends, the pawl 143 will be reset by the rebound of the spring 146 and re-engage with the ratchet 142, thus limiting the rotation direction of the ratchet 142 and reducing the probability of the equipment reversing.
