DETAILED DESCRIPTION
[0028] The utility model object of the utility model is further described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments cannot be described one by one here, but the implementation methods of the utility model are not limited to the following embodiments.
[0029] like Figure 1 As shown, the oiling and ejecting mechanism includes an oiling support seat 1, a longitudinal moving structure 2, a position fine-tuning structure 4 and an oiling and ejecting structure 3. The longitudinal moving structure 2 is installed on the oiling support seat 1, and the position fine-tuning structure 4 is installed on the top of the longitudinal moving structure 2, and the oiling and ejecting structure 3 is installed on the top of the position fine-tuning structure 4. The oiling support seat 1 plays a supporting role. The longitudinal moving structure 2 is used to move the oiling and ejecting structure 3 to a suitable position to facilitate the material removal in the next process. The position fine-tuning structure 4 is used to fine-tune the position of the oiling and ejecting structure 3 to facilitate alignment with other process equipment. The oiling and ejecting structure 3 is used to oil the sponge ring 5 and send out the sponge ring 5 after oiling.
[0030] like Figure 2As shown, the longitudinal movement structure 2 includes a longitudinal movement motor 21, a threaded block 22, a sliding base 23, two sliding blocks 24, two guide rails 25, and a longitudinal movement base 26. The two guide rails 25 are mounted at the front end of the oiling support base 1, parallel to each other. The longitudinal movement motor 21 is mounted at the rear end of the oiling support base 1. The two sliding blocks 24 slide on the two guide rails 25. The tops of the two sliding blocks are connected to the bottom of the sliding base 23. The threaded block 22 is bolted into the sliding base 23, and the longitudinal movement motor 21 is threadedly connected to the threaded block 22. The longitudinal movement base 26 is mounted on top of the sliding base 23, and the position fine-tuning mechanism 4 is mounted on top of the longitudinal movement base 26. The longitudinal movement motor 21 provides power for the longitudinal movement of the sliding blocks 24. The threaded block 22 is used to propel the sliding base 23 back and forth. The sliding base 23 increases the mounting area of the sliding blocks 24. The sliding blocks 24 cooperate with the guide rails 25 to achieve guided movement. The longitudinal movable base 26 is used to install the fixed position fine-adjustment structure 4 .
[0031] like Figure 3-5 As shown, the oiling and ejecting structure 3 includes a sponge ring feeding cylinder 31, a transmission rod positioning seat 32, a boss transmission rod 33, a groove ejection rod 34, an oiler 35 and an oiling base 36. The oiling base 36 is mounted on the position fine-tuning structure 4. The sponge ring feeding cylinder 31 is mounted on the left end of the oiling base 36, the transmission rod positioning seat 32 is mounted on the right side of the sponge ring feeding cylinder 31, the boss transmission rod 33 is slidably mounted on the transmission rod positioning seat 32, and the left end of the boss transmission rod 33 is connected to the sponge ring feeding cylinder 31 by a thread. An oiler bracket is provided on the oiling base 36, and the oiler 35 is mounted on the oiler bracket. A through hole is provided in the oiler 35, and the groove ejection rod 34 is slidably mounted in the through hole. The boss end of the boss transmission rod 33 is slidably connected to the groove end of the groove ejection rod 34.
[0032] The sponge ring feeding cylinder 31 provides power for the extension and retraction of the groove push rod 34. The transmission rod positioning seat 32 is used to install the boss transmission rod 33. The boss transmission rod 33 and the groove push rod 34 can slide relative to each other. When there is a slight steering misalignment between the boss transmission rod 33 and the oiler 35, the first groove push rod 34 can still enter the oiler 35 without interference. The oiler 35 oils the sponge ring 5 placed in the oiler 35 through the oil inlet pipes 352 on both sides, allowing the sponge ring 5 to absorb sufficient oil. The oiling base 36 is used to install and fix various components and acts as a bracket.
[0033] like Figure 5-8As shown, the oiler 35 includes a flow guide 351 and two oil inlet pipes 352, each connected to one side of the flow guide 351. The flow guide 351 is mounted on the oiling base 36. The center of the flow guide 351 is provided with a sponge placement area 351h, an oil collection groove 351d, and a guide rod hole 351g, which are connected in sequence. The groove push rod 34 passes through the guide rod hole 351g, the oil collection groove 351d, and the sponge placement area 351h in sequence. The sponge ring 5 can be placed in the sponge placement area 351h. Second oil guide pipes 351c are provided on the upper, lower, left, and right sides of the oil collection groove 351d, each connected to the oil collection groove 351d. The four second oil guide pipes 351c are connected to the center of the four first oil guide pipes 351b, and the four first oil guide pipes 351b are connected end to end. Two adjacent first oil guide tubes 351b are connected at their respective points with two oil inlet grooves 351a and two second sealing screw holes 351f. The two oil inlet grooves 351a are located on the front and rear sides of the guide member 351 and are connected to the two oil inlet tubes 352. The two second sealing screw holes 351f are located on the upper and lower sides of the guide member 351. The second oil guide tubes 351c located above and in front of the oil inlet grooves 351a are connected to the first sealing screw holes 351e. Both the first and second sealing screw holes 351e are sealed with sealing screws to prevent oil leakage.
[0034] The guide member 351 is used to guide the oil into the interior in a concentrated manner to lubricate the sponge ring 5. The oil inlet groove 351a is used to guide the oil from the oil inlet pipe 352 into the first oil guide pipe 351b; the first oil guide pipe 351b and the second oil guide pipe 351c are used to guide the oil entering the guide member 351; the oil collecting groove 351d is used to collect the oil from the four second oil guide pipes 351c to provide sufficient oil for the sponge ring 5; the first sealing screw hole 351e is used to form the hole required to be drilled for the second oil guide pipe 351c; the second sealing screw hole 351f is used to form the hole required to be drilled for the first oil guide pipe 351b; the guide rod hole 351g is used to guide the movement direction of the groove push rod 34; the sponge placement position 351h is used to fix the sponge ring 5; and the oil inlet pipe 352 is used to transport oil to the guide member 351.
[0035] The working process of the automatic oiling and ejecting mechanism of the sponge ring is described as follows: the sponge ring 5 is installed in the oiler 35 by the equipment in the previous process or manually. Oil enters the oiler 35 through the pipes on both sides of the oiler 35 and soaks the sponge ring 5. After the sponge ring 5 is soaked with sufficient oil for a certain period of time, the oiler 35 stops oiling the sponge ring 5. The longitudinal movement motor 21 of the longitudinal movement structure 2 drives the sliding base 23 and the longitudinal movement base 26 to move forward, that is, the oiling and ejecting structure 3 moves from back to front. After the oiling and ejecting structure 3 reaches the designated position, the sponge ring feeding cylinder 31 of the oiling and ejecting structure 3 pushes the boss transmission rod 33, and the boss transmission rod 33 then pushes the groove ejection rod 34 deep into the oiler 35. The boss transmission rod 33 pushes the oiled sponge ring 5 out of the oiler 35. The sponge ring 5 is sleeved on the front end of the boss transmission rod 33 and waits for the equipment in the next process to pick up the material.
[0036] like Figure 9-13 As shown, the position fine-tuning structure 4 includes a first adjustment seat 41, a second adjustment seat 42, a locking screw, an adjustment screw 43 and two limit posts 44. Each limit post 44 includes a stepped portion 44a, a transmission portion 44b and a limit cylindrical portion 44c connected in sequence. The first adjustment seat 41 is slidably connected to the second adjustment seat 42, and the second adjustment seat 42 is located below the first adjustment seat 41. An adjustment rail 42a is provided at the top of the second adjustment seat 42, and an adjustment slider 41a is provided at the bottom middle of the first adjustment seat 41. The adjustment slider 41a can slide relative to the adjustment rail 42a. Limiting grooves 42c are provided on both sides of the adjustment rail 42a. The limiting grooves 42c are located inside the second adjustment seat 42. The sliding ends of the two limit posts 44 are installed in the two limiting grooves 42c. The two limiting grooves 42c respectively limit the sliding ends of the two limit posts 44, so that they can only slide within a certain distance. The limiting groove 42c includes a limiting portion 42ca, a guide portion 42cb, and a clamping portion 42cc. The limiting cylindrical portion 44c is slidably mounted within the limiting portion 42ca, the transmission portion 44b is slidably mounted within the guide portion 42cb, and the stepped portion 44a is embedded in the clamping portion 42cc. Two locking screw holes 42b are provided on the sides of the limiting groove 42c (i.e., the limiting portion 42ca). Two locking screws are respectively installed in the two locking screw holes 42b and lock the sliding end of the limiting column 44. The clamping ends (i.e., the stepped portions 44a) of the two limiting columns 44 protrude from the clamping portion 42cc of the limiting groove 42c. The first adjustment seat 41 is provided with two bayonet holes, and the clamping ends (i.e., the stepped portions 44a) of the two limiting columns 44 are clamped into the two bayonet holes of the first adjustment seat 41. The adjusting screw 43 is screw-mounted on one end of the second adjusting seat 42 away from the limiting groove 42 c , and the adjusting screw 43 abuts against one end of the first adjusting seat 41 away from the bayonet.
[0037] Loosen the locking screw on the second adjustment seat 42 to unlock the limiting posts 44. The two limiting posts 44 can slide in and out of the limiting slots 42c, allowing the first adjustment seat 41 and the second adjustment seat 42 to slide relative to each other. Twist the adjustment screw 43, which pushes the first adjustment seat 41, which in turn drives the two limiting posts 44 outward, adjusting the relative position of the first adjustment seat 41 and the second adjustment seat 42, thereby fine-tuning the position of the oiling and ejection structure 3. Once the oiling and ejection structure 3 is positioned, tighten the locking screw on the second adjustment seat 42 to lock the limiting posts 44, preventing them from sliding freely within the limiting slots 42c.
[0038] The above specific implementation methods are preferred embodiments of the present invention and cannot limit the present invention. Any other changes or other equivalent replacement methods that do not deviate from the technical solution of the present invention are included in the scope of protection of the present invention.
