Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a headrest guide rod oil injection device. Background Technology

[0002] The headrest guide rod is a component of the car seat headrest. It is an important part that connects the headrest to the seat back and enables the headrest height adjustment. To ensure smooth headrest adjustment and improve the wear resistance and lifespan of the parts, a headrest guide rod oil injection device is required during the production process.

[0003] The headrest guide rod oil spraying device delivers the guide rod to the oil spraying station via a conveying mechanism. A sensor triggers the control system, driving the oil spraying assembly to evenly spray lubricating oil onto the guide rod surface according to a set amount. This achieves automated and standardized guide rod lubrication, ensuring the headrest's adjustability and component lifespan. During production, different guide rod specifications required changing positioning fixtures during processing. Adjusting the fixture spacing and nozzle position via a servo motor resulted in low switching efficiency. Later, a standardized positioning fixture with quick-change capability was adopted, but its adaptability to oil spraying processing of various guide rod types was weak, and frequent changes significantly reduced production efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a headrest guide rod oil spraying device, which aims to improve the problem that the existing standardized positioning fixtures have weak adaptability to oil spraying processing of various guide rods, and the frequent replacements greatly reduce production efficiency.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a headrest guide rod oil spraying device, comprising a worktable 1 and a housing 4. Guide rod fixing mechanisms 2 are provided on both the left and right sides of the worktable 1, used to fix guide rods of different sizes. A movable oil spraying mechanism 3 is provided on the upper part of the housing 4, used for oil spraying the guide rods. The guide rod fixing mechanism 2 includes a first motor 201, which is fixedly connected to the left and right sides of the worktable 1. A first gear 202 is fixedly connected to the output end of the first motor 201. A fixing plate 203 is provided on the front side of the first motor 201, fixedly connected to the worktable 1. A rotating shaft 204 is rotatably connected to the middle of the fixing plate 203. A second gear 205 is fixedly connected to the rear end of the rotating shaft 204, meshing with the first gear 202. A first connecting plate 206 is fixedly connected to the front end of the rotating shaft 204. A first gripper 207 is slidably connected to the upper part of the first connecting plate 206, and a second gripper 208 is slidably connected to the lower part of the first connecting plate 206. A sliding rod 212 is provided on the front side of both the first gripper 207 and the second gripper 208 to support them. An arc-shaped plate 209 is fixedly connected to the top of the fixing plate 203, and the first gripper 207 and the second gripper 208 are slidably connected to the arc-shaped plate 209. Support rods 210 are provided on both the left and right sides of the fixing plate 203, and the support rods 210 are fixedly connected to the worktable 1. A limit plate 211 is provided on the top of the support rods 210 to restrict the movement direction of the first gripper 207 and the second gripper 208. The sliding rod 212 is slidably connected to the limit plate 211. A sponge pad 5 is fixedly connected to the front end of both the first gripper 207 and the second gripper 208 to prevent direct hard contact between them.

[0032] Specifically, the guide rod is placed on the arc plate 209, and the first motor 201 is started. The first motor 201 is a permanent magnet DC motor. It uses the electromagnetic force generated by the stator magnetic field and the current in the rotor winding to form torque, causing the rotor to rotate. The commutator automatically changes the direction of the current in the armature winding to ensure that the torque direction remains unchanged, thus achieving continuous rotation. The operation of the first motor 201 drives the first gear 202 to rotate. Since the first gear 202 and the second gear 205 are in a meshing state, the second gear 205 will rotate synchronously with the first gear 202, and drive the shaft 204 connected to it to rotate together. When the shaft 204 rotates, it will cause the first gripper 207 and the second gripper 208 connected to it to move inward at the same time. The first gripper 207 and the second gripper 208 gradually approach and are aligned with the guide rod. The sponge pads 5 installed on the surfaces of the first gripper 207 and the second gripper 208 prevent direct hard contact between the grippers and the guide rod, thus preventing damage to the surface of the guide rod. When the first gripper 207 and the second gripper 208 contact the guide rod and apply a certain pressure, the first motor 201 is turned off, and the first gripper 207 and the second gripper 208 stop moving, fixing the guide rod on the arc plate 209. When it is necessary to replace the guide rod with a different model, the first motor 201 is started to make the first gear 202 rotate in the opposite direction. The second gear 205 will rotate in the opposite direction as well, and drive the rotating shaft 204 to rotate in the opposite direction, causing the first gripper 207 and the second gripper 208 to move outward, moving the first gripper 207 and the second gripper 208 away from each other, increasing the distance between them, and making it easier to fix guide rods of different sizes.

[0033] Reference Figure 1 and Figure 5 The mobile oil injection mechanism 3 includes a second motor 301, which is fixedly connected to the rear left end of the inner wall of the housing 4. A worm gear 302 is fixedly connected to the output end of the second motor 301. A worm wheel 303 is rotatably connected to the upper left side of the inner wall of the housing 4, meshing with the worm gear 302. A threaded rod 309 is fixedly connected to the front end of the worm wheel 303, and a slider 305 is threadedly connected to the middle of the threaded rod 309. Sliding grooves 304 are provided on both the left and right sides of the slider 305, and the slider 305 is slidably connected to the sliding grooves 304. The groove 304 is fixedly connected to the outer shell 4. An electric push rod 306 is fixedly connected to the bottom end of the slider 305. A second connecting plate 307 is fixedly connected to the output end of the electric push rod 306. An oil nozzle 308 is fixedly connected to the front end of the second connecting plate 307. A dust cover 6 is slidably connected to the outer wall of the oil nozzle 308 to prevent the oil nozzle 308 from being contaminated with dust and causing blockage. A telescopic sleeve 7 is fixedly connected to the bottom end of the slider 305 to isolate the electric push rod 306 from the external environment. The telescopic sleeve 7 is fixedly connected to the second connecting plate 307.

[0034] Specifically, after the guide rod is fixed, remove the dust cover 6 and start the electric push rod 306. The electric push rod 306 is a DC electric push rod. It reduces the speed and increases the torque through a reduction gearbox, driving the lead screw to rotate. The screw and nut helical transmission converts the rotational motion into the linear motion of the nut, which in turn pushes the push rod to extend or retract. The extension of the push rod drives the connected second connecting plate 307 to move downward, and at the same time drives the oil nozzle 308 installed at the bottom of the second connecting plate 307 to descend synchronously. When the oil nozzle 308 descends to an appropriate height above the guide rod, the electric push rod 306 is turned off. Then, the second motor 301 is started to rotate the worm gear 302. The second motor 301 is a permanent magnet DC motor. It uses the electromagnetic force generated by the stator magnetic field and the current in the rotor winding to form torque, causing the rotor to rotate, and with the help of the commutator... The current direction in the armature winding is automatically changed to ensure that the torque direction remains unchanged and achieve continuous rotation. Since the worm 302 and worm wheel 303 are in a meshing state, the worm wheel 303 will rotate synchronously with the worm 302 and drive the connected threaded rod 309 to rotate together. Since the sliding grooves 304 on both sides of the slider 305 restrict the rotation of the slider 305, the slider 305 will reciprocate along the sliding grooves 304 as the threaded rod 309 rotates, and at the same time drive the electric push rod 306 at the bottom to move synchronously, thereby driving the oil nozzle 308 to reciprocate, so as to spray oil on the surface of the guide rod. The dust cover 6 can prevent the oil nozzle 308 from being contaminated with dust and other impurities, avoiding blockage. The telescopic sleeve 7 isolates the electric push rod 306 from the external environment, preventing external dust and moisture from affecting the operation of the electric push rod 306.

[0035] Reference Figure 1 and Figure 2 The inner wall of the outer shell 4 is fixedly connected to the middle of the left and right sides of the support bracket 8. The front end of the support bracket 8 is fixedly connected to the fan 9 to blow away the excess lubricating oil on the guide rod. The middle of the worktable 1 is fixedly connected to the oil collection groove 10 to collect the excess lubricating oil. The bottom of the worktable 1 is fixedly connected to the four corners of the anti-slip pad 11 to prevent the device from sliding.

[0036] Specifically, the fan 9 is a 220AC fan, which drives the impeller to rotate and achieve directional airflow. This blows away excess lubricating oil on the guide rod, preventing excessive lubricating oil from affecting the use of the guide rod. The oil collection groove 10 is located below the guide rod and can collect excess lubricating oil. The anti-slip pad 11 at the bottom of the device can increase the friction between the device and the placement surface, prevent the device from sliding during operation, and ensure the stability of the device operation.

[0037] Working principle: The guide rod is placed on the arc plate 209, and the first motor 201 is started to rotate the first gear 202. Since the first gear 202 and the second gear 205 are in a meshing state, the second gear 205 will rotate synchronously with the first gear 202, driving the connected rotating shaft 204 to rotate. The rotation of the rotating shaft 204 causes the connected first gripper 207 and second gripper 208 to move inward simultaneously. The first gripper 207 and second gripper 208 will approach each other and contact the guide rod. The sponge pads 5 on the surfaces of the first gripper 207 and second gripper 208 prevent them from contacting the guide rod. The rods make direct, hard contact to avoid damage to the guide rod surface. When the two contact the guide rod and apply a certain pressure, the first motor 201 is turned off, and the first gripper 207 and the second gripper 208 stop on both sides of the guide rod and fix the guide rod. When changing to a different model of guide rod, the first motor 201 is started to make the first gear 202 rotate in the opposite direction, and the second gear 205 rotates in the opposite direction, which drives the rotating shaft 204 to rotate in the opposite direction, causing the first gripper 207 and the second gripper 208 to move outward. The first gripper 207 and the second gripper 208 move away from each other, making it easier to place a larger guide rod.

[0038] Once the guide rod is fixed, remove the dust cover 6 and start the electric push rod 306. The push rod extends and drives the second connecting plate 307 to descend, simultaneously driving the oil nozzle 308 to descend. When the oil nozzle 308 descends to an appropriate height above the guide rod, start the second motor 301 to rotate the worm 302. Since the worm 302 and worm wheel 303 are in a meshing state, the worm wheel 303 will rotate synchronously with the worm 302, driving the threaded rod 309 to rotate. Since the sliding grooves 304 on both sides of the slider 305 restrict the rotation of the slider 305, the slider 305 will reciprocate along the sliding grooves 304 as the threaded rod 309 rotates, simultaneously driving the electric push rod 306 at the bottom to move synchronously, thereby driving the oil nozzle 308 to reciprocate, performing oil spraying on the guide rod.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
