Description

Technical Field

[0001] This invention relates to the field of axle manufacturing technology, and in particular to an automatic oiling mechanism for axle manufacturing. Background Technology

[0002] The axle is one of the main components of a vehicle's operation. It mounts wheels at both ends, supports the frame and the weight of its various assemblies, protects components in the transmission system, and maintains the vehicle's normal driving on the road. The axle housing is a key component of the axle, crucial for its reliability. There are several methods for producing axle housings. One method involves integrally molding from a single steel tube blank, resulting in a strong and durable housing. However, this process requires oiling both ends of the tube blank before subsequent extrusion. Currently, this oiling is generally done manually, which is inefficient. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic oiling mechanism for axle manufacturing, which facilitates oiling and improves work efficiency.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an automatic oiling mechanism for axle manufacturing, comprising a conveying table for conveying tube blanks, an oiling structure provided in the middle section of the conveying table, the oiling structure comprising a frame and an oil roller assembly rotatably connected to the frame, the frame being provided with an inlet and an outlet, the oil roller assembly being provided in two sets, the two sets of oil roller assemblies being arranged on the same horizontal line, the oil roller assembly comprising multiple oil rollers, and an oil groove located at the bottom of the oil rollers being fixedly connected to the frame.

[0005] By adopting the above technical solution, the steel pipe billet is transported to the oil roller via the conveyor table. The billet is located between two sets of oil rollers. When the oil rollers rotate, they drive the oil in the oil tank to contact the two ends of the steel pipe, thus coating the two ends of the steel pipe billet with oil. After the steel pipe billet is coated with oil, it is transported away from the conveyor table at the discharge port of the machine frame. No manual labor is required, and the work efficiency is high.

[0006] A further configuration of the present invention is as follows: a pusher is hinged at the discharge port of the frame, the pusher is located between the two oil roller groups, a pusher cylinder is provided at the bottom of the pusher, the pusher cylinder is fixedly connected to the end of the pusher away from the discharge port, the pusher cylinder is connected to a controller, a sensing bracket is fixedly connected at the feed port, a proximity switch is fixedly connected on the sensing bracket, and the proximity switch is connected to the controller.

[0007] By adopting the above technical solution, when the conveyor table conveys the billet to the oil roller, the proximity switch senses and sends a signal to the controller. After the oil roller rotates and applies oil to both ends of the billet on the oil roller, the controller controls the push cylinder to push the pusher upward, pushing the steel billet on the pusher out of the oiling structure. The steel billet then enters the horizontal extrusion press along the conveyor table.

[0008] A further feature of the present invention is that the oiling structure includes a rotating shaft rotatably connected to the frame and a motor for driving the rotating shaft to rotate. A sprocket is fixedly connected to the end of the rotating shaft, and a sprocket is fixedly connected to the end of the oil roller. A transmission chain is sleeved between the sprocket and the sprocket.

[0009] By adopting the above technical solution, the motor drives the rotating shaft to rotate through the sprocket. The rotating shaft drives the oil roller to rotate through the sprocket and the sprocket connected to it by the transmission chain. The rotation of the oil roller drives the tube blank and another oil roller in the oil roller group that is in contact with the tube blank to rotate, thereby driving the oil in the oil tank to coat the two ends of the tube blank with oil.

[0010] A further configuration of the present invention is as follows: there are two oil rollers in the oil roller group, a support frame is fixedly connected in the oil groove, the support frame is located between the two oil rollers in the oil roller group, and a sliding member is fixedly connected to the bottom of the connection between the two ends of one oil roller in the oil roller group and the frame, and a slide rail is provided on the frame for the sliding member to slide.

[0011] By adopting the above technical solution, when the oil rollers apply oil to the tube blank, there is a certain distance between the oil rollers. When the tube blank diameter is small, the tube blank transported to the oil rollers falls onto the support frame through the distance between the oil rollers. The sliding oil roller pushes the tube blank from the support frame back onto the two oil rollers. The bottoms of the two sliding oil rollers are connected by the frame. When one of the sliding oil rollers is slid, the other sliding oil roller can be moved at the same time, keeping the two oil rollers on the same line, which is convenient and fast.

[0012] A further configuration of the present invention is as follows: a second motor for driving the sliding member to slide is fixedly connected to the frame, the second motor is connected to a second controller, the support frame and the oil tank are fixedly connected by a spring, a pressure sensor is fixedly connected to the bottom of the support frame, and the pressure sensor is connected to the second controller.

[0013] By adopting the above technical solution, the supporting force of the support frame on the tube blank is set between a suitable maximum and minimum value. When the value is less than the minimum or exceeds the maximum value, the pressure sensor sends a signal to the controller. When the tube blank falls onto the support frame, if the tube blank diameter is small, the bottom of the tube blank is lower between the two oil rollers, and the bottom exerts greater pressure on the support frame. Therefore, when the maximum supporting force is exceeded, the pressure sensor sends a signal to the second controller. The second controller controls the motor to drive the oil roller to slide towards the parallel oil roller, reducing the distance between the two oil rollers and lifting the tube blank between the two oil rollers, thereby better supporting the ends of the tube blank. Oiling is the first step; conversely, when the tube blank diameter is too large, the bottom of the tube blank is higher between the two oil rollers. In this case, the tube blank is prone to instability when oiling both ends, and the pressure on the support frame at the bottom is too small, failing to reach the minimum support force. The pressure sensor senses this and sends a signal to controller two. Controller two controls the motor to drive the oil roller to move away from the parallel oil roller, so that the tube blank can fall more stably between the two oil rollers, thus oiling both ends of the tube blank. The motor drives the connected lead screw to rotate, and the lead screw drives the connected frame to move back and forth. The frame drives the sliding parts to move back and forth in the slide rail, changing the distance between the two oil rollers. The whole process is flexible and stable, maintaining the stability of tube blanks of different diameters on the oil rollers, thus achieving more stable oiling.

[0014] A further feature of the present invention is that an oil scraper with an end in contact with the oil roller is rotatably connected to the frame.

[0015] By adopting the above technical solution, the oil scraper end contacts the oil roller to scrape off the oil on the oil roller. After scraping, an oil film is formed on the oil roller. When it contacts the tube blank, it can better apply oil to the tube blank. The oil scraper can be rotated and adjusted to form different distances between the oil scraper and the oil roller, so that the oil scraper produces an oil film of different thicknesses on the surface of the oil roller.

[0016] A further feature of the present invention is that the side of the scraper blade that contacts the oil roller is provided with an anti-wear rubber plate.

[0017] By adopting the above technical solution, the scraper blade contacts the oil roller through the anti-wear rubber plate, reducing wear on the oil roller.

[0018] A further provision of the present invention is that: a limiting structure is fixedly connected to both sides of the conveyor table, the limiting structure includes a limiting plate and an adjusting rod fixedly connected to the limiting plate, an adjusting frame for the adjusting rod to pass through is fixedly connected to the conveyor table, and an adjusting screw is threadedly connected to the adjusting frame to extend into the adjusting frame and contact the adjusting rod.

[0019] By adopting the above technical solution, when the conveyor table is conveying the tube blank, the adjusting screw is loosened, the limiting plate is moved to drive the adjusting rod to adjust to a suitable position according to the length of the tube blank, and the screw is tightened to fix the limiting plate on the adjusting frame. After the limiting plate is adjusted to a suitable position, the tube blank transportation is limited, reducing the movement and misalignment of the tube blank.

[0020] A further feature of the present invention is that oil receiving troughs are fixedly connected to both sides of the conveyor table corresponding to the discharge port of the frame.

[0021] By adopting the above technical solution, when the conveyor transports the oiled tube blank to the horizontal extruder, the oil receiving tank catches the oil dripping from both ends of the tube blank, reducing environmental pollution.

[0022] A further feature of the present invention is that the conveyor table is provided with a feeding port at one end near the inlet, and an anti-wear pad is fixedly connected to the feeding port.

[0023] By adopting the above technical solution, when the conveyor table transports the tube blank to the oil roller, the tube blank passes through the feed port onto the oil roller. The anti-wear pad at the feed port protects the tube blank and reduces wear on the tube blank during transportation.

[0024] The beneficial effects of this invention are:

[0025] 1. The steel pipe billet is transported to the oil roller via the conveyor table. The billet is located between two sets of oil rollers. When the oil roller rotates, it drives the oil in the oil tank to come into contact with both ends of the steel pipe, thus applying oil to both ends of the steel pipe billet. After oiling, it is pushed to the conveyor table by the pusher. The steel pipe billet enters the horizontal extrusion press along the conveyor table. No manual labor is required, and the working efficiency is high.

[0026] 2. By simultaneously moving two sliding oil rollers to adjust the distance between the two oil rollers in the same oil roller group, the steel tube blank can be stably held on the oil rollers. The oil rollers apply oil to both ends of the steel tube blank, which is suitable for strong stability.

[0027] 3. The distance between the scraper and the oil roller can be adjusted as needed to scrape the oil off the surface of the oil roller, forming oil films of different thicknesses on the surface of the oil roller. This makes oiling the two ends of the tube blank more effective.

[0028] 4. The feed inlet is equipped with an anti-wear pad, the scraper is equipped with an anti-wear rubber plate, and the two sides of the conveyor table are equipped with a limiting structure to limit the transport of the tube blank, so that the whole device can operate stably with minimal wear on the tube blank.

[0035] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0036] Example 1: An automatic oiling mechanism for axle manufacturing, such as... Figure 1 , Figure 2As shown, the conveyor includes a conveyor table 1 for conveying tube blanks. The middle section of the conveyor table 1 has an oiling structure, which includes a frame 2 and an oil roller assembly rotatably connected to the frame 2. The frame 2 has an inlet 4 and an outlet 5. The conveyor table 1 has a feeding port at one end of the inlet 4, and an anti-wear pad 6 is fixedly connected to the feeding port. Two oil roller assemblies are set up, positioned on the same horizontal line. Each oil roller assembly includes two oil rollers 3. An oil trough 7 located at the bottom of the oil rollers 3 is fixedly connected to the frame 2. 1. Oil receiving grooves 12 are provided on both sides of the discharge port 5 of the corresponding frame 2. A pusher 8 is hinged to the discharge port 5 on the frame 2. The pusher 8 is located between the two oil roller groups. A push cylinder 22 is provided at the bottom of the pusher 8. The push rod of the push cylinder 22 is fixedly connected to the end of the pusher 8 away from the discharge port 5. The push cylinder 22 is connected to a controller 1. A sensing bracket 10 is fixedly connected to the feed port 4. A proximity switch 11 is fixedly connected to the sensing bracket 10. The proximity switch 11 is connected to the controller 1.

[0037] After the steel billet is transported to the oil roller 3 through the feeding port via the conveyor table 1, the billet is located between two sets of oil rollers. The rotation of the oil roller 3 in the oil roller set drives the oil in the oil tank 7 to coat the two ends of the billet on the oil roller 3. The proximity switch 11 senses and sends a signal to the controller 1. The controller 1 controls the push cylinder 22 to push the pusher 8 upward, pushing the steel billet on the pusher 8 out of the oiling structure. The steel billet enters the horizontal extrusion press along the conveyor table 1. The push cylinder 22 drives the pusher 8 to fall, waiting for the next billet to be transported to the oil roller 3.

[0038] like Figure 1 As shown, the oiling structure also includes a rotating shaft 23 rotatably connected to the frame 2 and a motor 13 driving the rotating shaft 23 to rotate. A sprocket 14 is fixedly connected to the end of the rotating shaft 23, and a sprocket 25 is fixedly connected to the end of the oil roller 3. A transmission chain 16 is sleeved between the sprocket 14 and the sprocket 2.

[0039] Motor 13 drives rotating shaft 23 to rotate via sprocket. Rotating shaft 23 drives sprocket 14 at the end to rotate. Sprocket 14 drives transmission chain 16 to rotate. Transmission chain 16 drives oil roller 3 connected to sprocket 2 15 to rotate. The rotation of oil roller 3 drives the oil in oil tank 7 to complete the oiling of both ends of tube blank.

[0040] like Figure 3 As shown, a support frame 17 is fixedly connected inside the oil tank 7. The support frame 17 is located between two oil rollers 3 in the oil roller group. Sliding parts 18 are fixedly connected to the bottom of the connection between one oil roller 3 and the frame 2 at both ends. The frame 2 is provided with a slide rail 19 for sliding the sliding parts 18. A second motor 21 for driving the sliding parts 18 is fixedly connected to the frame 2. The second motor 21 is connected to a second controller. The support frame 17 and the oil tank 7 are fixedly connected by a spring. A pressure sensor is fixedly connected to the bottom of the support frame 17. The pressure sensor is connected to the second controller.

[0041] The pressure sensor is used to sense the tube blank on the support frame 17. When the tube blank with a smaller diameter falls onto the support frame 17, the support frame 17, which is connected to the oil groove 7 by a spring, is pressed down. The controller 2 controls the motor 21 to drive the sliding member 18 to move the oil roller 3 closer to the oil roller 3 parallel to it. When the tube blank with a larger diameter falls onto the support frame 17, the controller 2 controls the motor 21 to drive the sliding member 18 to move the oil roller 3 away from the oil roller 3 parallel to it.

[0042] like Figure 3 , Figure 4 As shown, an oil scraper 20 with its end in contact with the oil roller 3 is rotatably connected to the frame 2, and the side of the oil scraper 20 in contact with the oil roller 3 is provided with an anti-wear rubber plate.

[0043] Rotate and adjust the scraper 20 to create different distances between the scraper 20 and the oil roller 3. After the oil roller 3 starts to rotate, the scraper 20 scrapes the oil on the surface of the oil roller 3 to form an oil film.

[0044] like Figure 1 As shown, a limiting structure 9 is fixedly connected to both sides of the conveyor table 1. The limiting structure 9 includes a limiting plate 91 and an adjusting rod 92 fixedly connected to the limiting plate 91. An adjusting frame 93 for the adjusting rod 92 to pass through is fixedly connected to the conveyor table 1. An adjusting screw 94 is threadedly connected to the adjusting frame 93, which extends into the adjusting frame 93 and contacts the adjusting rod 92.

[0045] During adjustment, loosen the adjusting screw 94, move the limiting plate 91 to move the adjusting rod 92 to the appropriate position on the adjusting frame 93 according to the length of the tube blank, and then tighten the screw to fix the limiting plate 91 on the adjusting frame 93.

[0046] In summary, after the tube blank is transported to the oil roller 3 through the feed port by the conveyor table 1, the tube blank is located between the two sets of oil rollers. When the smaller diameter tube blank falls onto the support frame 17, the controller 2 controls the motor 21 to drive the sliding member 18 to move the oil roller 3 closer to the oil roller 3 parallel to it. When the larger diameter tube blank falls onto the support frame 17, the controller 2 controls the motor 21 to drive the sliding member 18 to move the oil roller 3 away from the oil roller 3 parallel to it. The rotation of the oil roller 3 in the oil roller group causes the oil in the oil groove 7 to coat the two ends of the tube blank on the oil roller 3. The scraper 20 scrapes the oil off the surface of the oil roller 3. At the same time, the proximity switch 11 senses the tube blank and sends a signal to the controller 1. The controller 1 controls the push cylinder 22 to push the pusher 8 upward, pushing the steel tube blank on the pusher 8 out of the oiling structure. The steel tube blank enters the horizontal extrusion press along the conveyor table 1. The push cylinder 22 drives the pusher 8 to fall, waiting for the next tube blank to be transported to the oil roller 3. The whole process is repeated.
