Description

Technical Field

[0001] The invention relates to the technical field of helical gear assembly, in particular to an assembly robot for helical gear assembly. Background Art

[0002] Helical gears refer to a type of gear used in motor transmission systems. Their teeth are inclined at a certain angle to the axis and arranged in a spiral shape. The assembly robot used for helical gear assembly consists of a conveying structure, an oiling structure, a combined robotic arm and other structures. The gear is sent to the oiling structure through the conveying structure. After oiling, it needs to be interference fit with the shaft body, and then the robotic arm uses a flexible clamp to clamp the helical gear and adjust the angle to install it in the motor housing.

[0003] When the existing helical gear is moved to the oil filling position through the conveying structure, the oil filling head is often inserted into the gear hole to fill oil. However, the gear hole only needs to adhere to the side of the oil so that the helical gear and the shaft can be assembled smoothly to avoid wear. However, the oil filling head is inserted into the hole to fill oil, causing the oil to spread outward from the middle of the hole and contact the inner side of the hole, thereby causing unnecessary consumption of oil. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the present invention provides an assembly robot for assembling helical gears, which solves the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: an assembly robot for assembling helical gears, comprising a conveying component and an oiling component, the conveying component comprising a guide rail, and a groove is provided on the surface of the guide rail, a rack is provided on one side of the inner wall of the groove, an electric pulley is slidably connected to the surface of the guide rail, and the top surface of the electric pulley is rotatably connected to a supporting plate, an oil cylinder is fixed to the bottom of the supporting plate, and a transmission gear is fixed to the bottom of the oil cylinder, and an oil outlet hole is provided on the side of the transmission gear in a ring shape, the oiling component comprises a lifting drive mechanism arranged on one side of the end of the guide rail, and a horizontal rail is fixed to the end of the lifting drive mechanism, the interior of the horizontal rail is connected to an oiling frame through a horizontal spring, and an oiling pipe is provided in the middle of the oiling frame, the bottom of the oiling pipe is sleeved with a right-angle tube, and the outer wall of the right-angle tube is sleeved with an oiling panel through an elastic spring, an oiling hole is provided on the side of the outer side surface of the oiling panel, and a movable ball is embedded in the middle of the outer side surface of the oiling panel, and a guide arc piece is provided at the bottom of the oiling panel.

[0006] Furthermore, the bottom of the inner wall of the groove is sloped, and the slope is 2°.

[0007] Furthermore, the transmission gear is meshed with the rack, and the supporting plate is connected to the electric pulley through the oil cylinder, the transmission gear, and the rack.

[0008] Furthermore, a funnel tube is provided at the lower end of the bottom of the inner wall of the groove, and the end of the funnel tube is connected to an oil recovery tank.

[0009] Furthermore, the oil filling pipe and the helical gear are arranged one to one, and the helical gear is placed on the surface of the supporting plate.

[0010] Furthermore, the outer wall of the guide arc piece is provided with a flexible rubber sleeve, and the bottom of the guide arc piece is located directly below the oil filling pipe.

[0011] Furthermore, a laser positioning sensor is provided at the bottom of the oil filling rack, and the laser positioning sensor is used to locate the position of the helical gear hole.

[0012] Furthermore, a shaft assembly mechanism is provided on one side of the lifting drive mechanism, and a mechanical arm is provided on one side of the shaft assembly mechanism.

[0013] Furthermore, a flexible clamp is provided at the end of the robotic arm, and a conveyor belt is provided below the shaft assembly mechanism.

[0014] Furthermore, a movable carrier is provided on the surface of the conveyor belt, and a motor housing is placed on the surface of the movable carrier.

[0015] The present invention provides an assembly robot for helical gear assembly, which has the following beneficial effects: 1. This helical gear assembly robot extends an oiling panel into the hole and affixes it to the inner wall while the electric pulley carries the helical gear in translation, moving synchronously with it. This completes the oiling process while the helical gear is being transferred to the next process. During oiling, the movement of the electric pulley causes the transmission gear to roll along the rack surface, driving the helical gear to rotate while moving. This causes the oiling panel to adhere to the inner wall of the hole via the movable ball bearing, effectively rolling. As a result, after the helical gear rotates one full revolution, lubricant is fully applied to the inner wall of the hole, effectively improving lubricant utilization and eliminating the need to fill the entire hole with lubricant, which would cause unnecessary consumption.

[0016] 2. This helical gear assembly robot, after lubricating oil adheres to the inner wall of the helical gear hole, slides down the inner wall of the oil cylinder under the action of gravity and into the transmission gear. As the lubricating oil inside the transmission gear increases, it flows out of the oil outlet hole as the gear rotates. As the transmission gear rolls along the rack surface, the lubricating oil adheres to both surfaces, thereby enhancing the smoothness of the transmission gear's rolling along the rack surface and preventing jamming.

[0017] 3. This helical gear assembly robot uses a laser positioning sensor to locate the moving helical gear hole. When the hole and the oil filling pipe coincide, the robot lowers the oil filling pipe. During this descent, a guide arc with a flexible rubber sleeve on its outer wall cooperates with the oil filling panel, which slides along the outer wall of the right-angle tube bottom due to the elastic action of an elastic spring. As the oil filling panel descends, it carries the movable ball bearing with it and abuts against the inner surface of the hole. This prevents the oil filling panel from being unable to enter the hole due to a misalignment between the movement of the helical gear and the descent speed of the oil filling pipe. Furthermore, the robot can accommodate helical gear holes of different inner diameters. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0021] like Figures 1-8 As shown, the present invention provides a technical solution: an assembly robot for helical gear assembly, comprising a conveying component 1 and an oiling component 2, the conveying component 1 comprises a guide rail 101, and a groove 102 is provided on the surface of the guide rail 101, a rack 103 is provided on one side of the inner wall of the groove 102, an electric pulley 104 is slidably connected to the surface of the guide rail 101, and the top surface of the electric pulley 104 is rotatably connected to a supporting plate 105, an oil cylinder 106 is fixed to the bottom of the supporting plate 105, and the bottom of the oil cylinder 106 is fixed to the bottom of the oil cylinder 106. A transmission gear 107 is fixed, and an oil outlet hole 108 is opened on the side of the transmission gear 107 in a ring shape. The oil filling assembly 2 includes a lifting drive mechanism 201 arranged on one side of the end of the guide rail 101, and a horizontal rail 202 is fixed to the end of the lifting drive mechanism 201. The interior of the horizontal rail 202 is connected to an oil filling frame 203 through a horizontal spring, and an oil filling pipe 204 is provided in the middle of the oil filling frame 203. The bottom of the oil filling pipe 204 is sleeved with a right-angle pipe 205, and the outer wall of the right-angle pipe 205 is connected to the guide rail 101. The elastic spring 210 is provided with an oil filling panel 206, an oil filling hole 207 is provided on the side of the outer side of the oil filling panel 206, and a movable ball 208 is embedded in the middle of the outer side of the oil filling panel 206. A guide arc piece 209 is provided at the bottom of the oil filling panel 206. The bottom of the inner wall of the groove 102 is sloped, and the slope is 2°. The transmission gear 107 is meshed with the rack 103, and the supporting plate 105 is connected to the electric slide through the oil cylinder 106, the transmission gear 107, the rack 103 and the electric slide. The car 104 is connected in transmission, a funnel tube 3 is provided at the lower end of the bottom of the inner wall of the groove 102, and the end of the funnel tube 3 is connected to the oil recovery tank, the oil filling pipe 204 and the helical gear are arranged one-to-one, and the helical gear is placed on the surface of the supporting plate 105, the outer wall of the guide arc piece 209 is provided with a flexible rubber sleeve, and the bottom of the guide arc piece 209 is located directly below the oil filling pipe 204, and a laser positioning sensor is provided at the bottom of the oil filling frame 203, and the laser positioning sensor is used to locate the position of the helical gear hole; The specific operation is as follows: the helical gear to be oiled is placed on the supporting plate 105, and the supporting plate 105 is carried by the electric pulley 104 to slide along the surface of the guide rail 101. When the laser positioning sensor detects that the hole of the helical gear is directly below the oil filling pipe 204, the lifting drive mechanism 201 such as the cylinder, hydraulic cylinder or electric telescopic rod drives the horizontal rail 202 and the oil filling rack 203 to descend, so that the oil filling pipe 204 carries the oil filling panel 206 to descend into the hole of the helical gear. If there is a slight deviation or the inner diameter of the hole is small during the descent process, the guide arc piece 209 will first contact the top of the hole. During the descent process, the guide arc piece 209 is subjected to force so that the oil filling panel 206 applies pressure to the elastic spring 210 to contract it, thereby causing the oil filling panel 206 to slide on the outer wall of the right-angle tube 205, thereby reducing the distance between the oil filling panel 206 and the oil filling pipe 204, so that the oil filling panel 206 can enter the hole of the helical gear; After the oil filling panel 206 enters the helical gear hole, the outer side of the oil filling panel 206 faces the inner side of the hole under the action of the elastic spring 210, and the movable ball 208 sticks to the inner side of the hole, while the electric pulley 104 keeps moving. During the movement, the oil filling panel 206 is forced to push the oil filling frame 203 to move horizontally along the surface of the horizontal rail 202. During the translation process, the oil filling pipe 204 fills the oil filling panel 206 with oil through the right-angle pipe 205. The lubricating oil flows out of the oil filling hole 207 and directly flows to the inner side of the hole. The oil slides down on the inner side of the hole under the action of gravity. During the movement of the electric pulley 104, the transmission gear 107 rolls along the surface of the rack 103, so that the oil cylinder 106 drives the supporting plate 105 to rotate the bevel gear. As a result, during the synchronous movement of the bevel gear and the oiling panel 206, the inner surface of the hole of the bevel gear keeps in contact with the movable ball 208 and rotates, so that the lubricating oil flowing out of the oiling hole 207 is applied to different side parts of the hole, so that the side surface inside the hole is evenly adhered to the lubricating oil. After the bevel gear moves and rotates for many cycles, the lifting drive mechanism 201 drives the horizontal rail 202 and the oiling rack 203 to rise, so that the oiling panel 206 is separated from the inside of the hole. At this time, the oiling panel 206 loses the force, so that itself and the oiling rack 203 are reset under the elastic action of the elastic spring 210 and the horizontal spring to wait for the next round of oiling operation, and the electric pulley 104 carries the bevel gear to move to the next process; After the oiling is completed, the lubricating oil adhering to the inner surface of the hole slides down under the action of gravity and falls into the oil cylinder 106. With each round of oiling, the dripping lubricating oil slides down along the oil cylinder 106 and enters the interior of the transmission gear 107. Then, it flows out from the oil outlet 108 on the outer surface of the transmission gear 107. When the transmission gear 107 rolls along the surface of the rack 103 due to the movement of the electric pulley 104, the flowing lubricating oil can adhere to the surfaces of the transmission gear 107 and the rack 103, thereby lubricating the meshing of the transmission gear 107 and the rack 103. The lubricating oil adhering to the surfaces of the transmission gear 107 and the rack 103 will also fall to the bottom of the groove 102 due to gravity. The bottom of the groove 102 is designed with a slope, so that the lubricating oil is collected at the lower end and finally flows along the funnel 3 to the oil recovery tank for recovery. In the present invention, the helical gear is oiled and assembled in a dust-free environment to prevent impurities such as dust from entering the groove 102 and mixing with the lubricating oil, thereby affecting the meshing between the transmission gear 107 and the rack 103. Based on the above description, the present invention extends the oil filling panel 206 into the hole and sticks to the inner wall while the electric pulley 104 carries the bevel gear for translation and moves synchronously therewith, thereby completing the oil filling operation while the bevel gear is transmitted to the next process. During the oil filling, the movement of the electric pulley 104 causes the transmission gear 107 to roll along the surface of the rack 103, thereby driving the bevel gear to rotate while moving, so that the oil filling panel 206 sticks to the inner wall of the hole through the movable ball 208 and rolls in disguised form. Therefore, after the bevel gear rotates one circle, the lubricating oil can be fully coated on the inner wall of the hole, which is beneficial to improve the utilization rate of the lubricating oil, and there is no need to fill the entire hole with lubricating oil, causing unnecessary consumption.

[0022] In the present invention, after the lubricating oil adheres to the inner wall of the helical gear hole, it will slide down the inner wall of the oil cylinder 106 to the inside of the transmission gear 107 under the action of gravity. As the lubricating oil inside the transmission gear 107 increases and it rotates, the lubricating oil flows out from the oil outlet 108, so that when the transmission gear 107 rolls along the surface of the rack 103, the lubricating oil will adhere to the surfaces of both, thereby enhancing the smoothness of the transmission gear 107 when rolling along the surface of the rack 103 to avoid jamming.

[0023] The present invention locates the position of the moving helical gear hole through a laser positioning sensor, and when the hole coincides with the oil filling pipe 204, the oil filling pipe 204 is lowered. During the descent process, the guide arc piece 209 with a flexible rubber sleeve on the outer wall cooperates with the oil filling panel 206 to slide along the bottom outer wall of the right-angle tube 205 through the elastic action of the elastic spring 210, so that the oil filling panel 206 carries the movable ball 208 to stick to the inner side surface of the hole as it descends, thereby avoiding the situation where the oil filling panel 206 cannot enter the inside of the hole due to the deviation between the movement of the helical gear and the descending speed of the oil filling pipe 204, and can also adapt to helical gear holes of different inner diameters.

[0024] like Figures 1-8 As shown, a shaft assembly mechanism 4 is provided on one side of the lifting drive mechanism 201, and a mechanical arm 5 is provided on one side of the shaft assembly mechanism 4, and a flexible clamping claw 6 is provided at the end of the mechanical arm 5. A conveyor belt 7 is provided below the shaft assembly mechanism 4, and a mobile carrier 8 is provided on the surface of the conveyor belt 7, and a motor housing 9 is placed on the surface of the mobile carrier 8; The specific operation is as follows: during the oiling operation, the motor housing 9 is pre-placed on the mobile carrier 8, and the conveyor belt 7 is started to enable the mobile carrier 8 to carry the motor housing 9 to the assembly position. After the oiling is completed, the helical gear slides back with the electric pulley 104 and moves to the shaft assembly mechanism 4. At this time, the robotic arm 5 adjusts the angle and uses the flexible clamp 6 to clamp the helical gear and place it on the assembly position of the shaft assembly mechanism 4, and then the shaft assembly mechanism 4 assembles the shaft and the helical gear together. The specific structural principle of the shaft assembly mechanism 4 is the existing public technology, so it will not be repeated. The helical gear after the shaft is assembled is clamped by the flexible clamp 6 again and assembled into the motor housing 9 after adjusting the angle by the robotic arm 5, thereby completing the assembly.

[0025] In summary, when the helical gear assembly robot is used, the helical gear to be oiled is first placed on the supporting plate 105, and the supporting plate 105 is carried by the electric pulley 104 to slide along the surface of the guide rail 101. When the laser positioning sensor detects that the hole position of the helical gear is directly below the oil filling pipe 204, the lifting drive mechanism 201 drives the horizontal rail 202 and the oil filling frame 203 to descend, so that the oil filling pipe 204 carries the oil filling panel 206 to descend into the hole position of the helical gear. If there is a slight deviation or the inner diameter of the hole position is small during the descent process, the guide arc piece 209 will first contact the top of the hole position. During the descent process, the guide arc piece 209 is subjected to force so that the oil filling panel 206 applies pressure to the elastic spring 210 to contract it, thereby causing the oil filling panel 206 to slide on the outer wall of the right-angle tube 205, thereby reducing the distance between the oil filling panel 206 and the oil filling pipe 204, so that the oil filling panel 206 can enter the hole position of the helical gear. After the oil filling panel 206 enters the helical gear hole, the outer side of the oil filling panel 206 faces the inner side of the hole under the action of the elastic spring 210, and the movable ball 208 sticks to the inner side of the hole, while the electric pulley 104 keeps moving. During the movement, the oil filling panel 206 is forced to push the oil filling frame 203 to move horizontally along the surface of the horizontal rail 202. During the translation process, the oil filling pipe 204 fills the oil filling panel 206 with oil through the right-angle pipe 205, and the lubricating oil flows out from the oil filling hole 207 and directly flows to the inner side of the hole. During the movement of the electric pulley 104, the transmission gear 107 rolls along the surface of the rack 103, so that the oil cylinder 106 drives the supporting plate 105 to rotate the bevel gear. As a result, during the synchronous movement of the bevel gear and the oiling panel 206, the inner surface of the hole of the bevel gear keeps in contact with the movable ball 208 and rotates, so that the lubricating oil flowing out of the oiling hole 207 is applied to different side parts of the hole, so that the side surface inside the hole is evenly adhered to the lubricating oil. After the bevel gear moves and rotates for many cycles, the lifting drive mechanism 201 drives the horizontal rail 202 and the oiling rack 203 to rise, so that the oiling panel 206 is separated from the inside of the hole. At this time, the oiling panel 206 loses the force, so that itself and the oiling rack 203 are reset under the elastic action of the elastic spring 210 and the horizontal spring to wait for the next round of oiling operation, and the electric pulley 104 carries the bevel gear to move to the next process; After the oiling is completed, the lubricating oil adhering to the inner surface of the hole slides down under the action of gravity and falls into the oil cylinder 106. With each round of oiling, the dripping lubricating oil slides down along the oil cylinder 106 and enters the interior of the transmission gear 107. Then, it flows out from the oil outlet 108 on the outer surface of the transmission gear 107. When the transmission gear 107 rolls along the surface of the rack 103 due to the movement of the electric pulley 104, the flowing lubricating oil can adhere to the surfaces of the transmission gear 107 and the rack 103, thereby lubricating the meshing of the transmission gear 107 and the rack 103. The lubricating oil adhering to the surface of the transmission gear 107 and the rack 103 will also fall to the bottom of the groove 102 due to gravity. The bottom of the groove 102 is designed with a slope, so that the lubricating oil gathers at the lower end and finally flows along the funnel tube 3 to the oil recovery tank for recovery. During the oiling operation, the motor housing 9 is pre-placed on the mobile carrier 8, and the conveyor belt 7 is started to enable the mobile carrier 8 to carry the motor housing 9 to the assembly position. After the oiling is completed, the helical gear slides back with the electric pulley 104 and moves to the shaft assembly mechanism 4. At this time, the robotic arm 5 adjusts the angle and uses the flexible clamp 6 to clamp the helical gear and place it on the assembly position of the shaft assembly mechanism 4, and then the shaft assembly mechanism 4 assembles the shaft and the helical gear together. The specific structural principle of the shaft assembly mechanism 4 is the existing public technology, so it will not be repeated. The helical gear after the shaft is assembled is clamped by the flexible clamp 6 again and assembled into the motor housing 9 after the angle is adjusted by the robotic arm 5, thereby completing the assembly.
