Description

Technical Field

[0001] This invention relates to the field of oiling mechanism technology, and more specifically, to an automatic oiling motion mechanism and motion method. Background Technology

[0002] Products with internal mechanical structures often require the application of grease to the contact surfaces between moving parts to prevent mechanical wear. This is typically done manually, with workers wearing gloves applying grease to the surfaces using their fingers. Manual grease application is not only inefficient but also prone to incomplete application, affecting subsequent processing and ultimately impacting the quality of the final product.

[0003] In the prior art, such as Chinese Patent Application No. 202311687045.6, an oiling mechanism is disclosed, including an oiling mechanism, which includes an oil outlet; a placement structure for placing the product to be oiled; and a motion mechanism with an oil storage wheel mounted on it, the oil storage wheel having an oil storage structure. The motion mechanism can control the oil storage wheel to move to a position opposite to the oil outlet, so that the oil outlet applies oil to the oil storage structure. The motion mechanism can also move the oil storage wheel to a position that mates with the product to be oiled, so that after the oil storage structure is connected to the product, the motion mechanism can drive the oil storage wheel to rotate to apply oil to the product. This mechanism first applies lubricant to the oil storage structure of the oil storage wheel through the oil outlet, and then moves the oil storage wheel to the position that mates with the product through the motion mechanism. That is, when the oil storage structure needs to be replenished, it needs to return to the oiling mechanism, the operation process is complicated, and the oiling efficiency is low. Therefore, it is necessary to propose an automatic oiling motion mechanism and motion method to at least partially solve the problems existing in the prior art. Summary of the Invention

[0047] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0048] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0049] Example 1:

[0050] like Figure 1-6 As shown, the present invention provides an automatic oiling mechanism, comprising:

[0051] The system comprises a motor 1, an electromagnetic switching mechanism 2, a peristaltic pump 3, a lead screw 4, and a support frame 5. The motor 1, electromagnetic switching mechanism 2, peristaltic pump 3, and lead screw 4 are mounted on the support frame 5. The peristaltic pump 3 has a first transmission group at its front end, and the lead screw 4 has a second transmission group at its front end. The output end of the electromagnetic switching mechanism 2 has a movable connecting rod frame 6, which connects the motor 1 to either the first or second transmission group. The lead screw 4 is used to drive the movement of the injection needle. The peristaltic pump 3 is connected to the oil supply equipment and is used to deliver oil to the injection needle.

[0052] A method for operating an automatic oiling mechanism, comprising the aforementioned automatic oiling mechanism, with the following specific steps:

[0053] When the electromagnetic switching mechanism 2 is activated, it pulls back the movable linkage 6. The movable linkage 6 connects the motor 1 to the second transmission group. The motor 1 is disconnected from the first transmission group of the peristaltic pump 3. The motor 1 drives the lead screw 4 to rotate through the second transmission group. The lead screw 4 drives the oil injection needle to move forward or backward.

[0054] The electromagnetic switching mechanism 2 pushes out the movable linkage 6, which connects the motor 1 to the first transmission group. The motor 1 is then disconnected from the second transmission group of the lead screw 4. The motor 1 drives the peristaltic pump 3 to rotate through the first transmission group, and the peristaltic pump 3 delivers oil to the injection needle.

[0055] The working principle and beneficial effects of the above technical solution are as follows:

[0056] The present invention provides an automatic oiling mechanism. In use, the movable linkage 6 is pulled back and pushed out by the action of the electromagnetic switching mechanism 2. The electromagnetic switching mechanism 2 is set as an electromagnet with switchable magnetism. The specific movement process is as follows: when oiling, the electromagnetic switching mechanism 2 switches the magnetism to generate an attraction force on the movable linkage 6, pulling the movable linkage 6 back. The movable linkage 6 connects the motor 1 to the second transmission group, and the motor 1 is disengaged from the first transmission group of the peristaltic pump 3. The motor 1 drives the lead screw 4 to rotate through the second transmission group. The lead screw 4 drives the oil injection needle to move forward or backward. The oil injection needle moves along the length direction of the lead screw 4 to perform oiling.

[0057] When the injection needle is replenished with oil, the electromagnetic switching mechanism 2 switches the magnetism to generate a repulsive force on the movable connecting rod 6, pushing the movable connecting rod 6 out. The movable connecting rod 6 connects the motor 1 to the first transmission group, and the motor 1 is disconnected from the second transmission group of the lead screw 4. The motor 1 drives the peristaltic pump 3 to rotate through the first transmission group, and the peristaltic pump 3 delivers oil to the injection needle.

[0058] The present invention provides an automatic oiling mechanism in which an electromagnet is used for power push and pull between the motor 1, the peristaltic pump 3 and the lead screw 4, so that the output end of the motor 1 and the peristaltic pump 3 and the lead screw 4 form a structure that is in contact with and disengaged at the same time. This allows for quick switching between two action modes: oiling along the length of the lead screw 4 and oiling to the injection needle, thereby improving the efficiency of oiling and realizing the automated operation of oiling.

[0059] Example 2:

[0060] like Figure 1-6 As shown, based on the above embodiment 1, the movable linkage frame 6 includes: a rotating shaft 7, an upper support arm 8, a first lower support arm 9, and a second lower support arm 10. The rotating shaft 7 is rotatably connected to the support frame 5. The upper support arm 8, the first lower support arm 9, and the second lower support arm 10 are all connected to the same side of the rotating shaft 7 and rotate synchronously. The first lower support arm 9 and the second lower support arm 10 form an acute angle. The end of the first lower support arm 9 is connected to a peristaltic pump connecting gear 11, and the end of the second lower support arm 10 is connected to a lead screw connecting gear 12.

[0061] When the motor gear 13 at the output end of motor 1 is connected to the peristaltic pump connecting gear 11, the peristaltic pump connecting gear 11 is simultaneously connected to the first transmission group. When the motor gear 13 at the output end of motor 1 is connected to the lead screw connecting gear 12, the lead screw connecting gear 12 is simultaneously connected to the second transmission group.

[0062] The working principle and beneficial effects of the above technical solution are as follows:

[0063] A motor gear 13 is connected to the output shaft of motor 1, and a peristaltic pump connecting gear 11 and a lead screw connecting gear 12 are installed on the movable linkage 6. When the electromagnetic switching mechanism 2 is activated, it drives the movable linkage 6 to rotate around the rotating shaft 7. When the movable linkage 6 rotates to the point where the motor gear 13 is connected to the peristaltic pump connecting gear 11, the peristaltic pump connecting gear 11 is simultaneously connected to the gear of the first transmission group. That is, the motor gear 13 and the first transmission group form a gear meshing transmission structure, which can drive the first transmission group to move and drive the drive shaft of the peristaltic pump 3 to rotate. When the movable linkage 6 rotates to the point where the motor gear 13 is connected to the lead screw connecting gear 12, the lead screw connecting gear 12 is simultaneously connected to the second transmission group. That is, the motor gear 13 and the second transmission group form a gear meshing transmission structure, which can drive the second transmission group to move and drive the drive shaft of the lead screw 4 to rotate.

[0064] The first lower support arm 9 and the second lower support arm 10 form an acute angle, which controls the rotation angle of the rotating shaft 7 within a small range during action switching, reduces the stroke requirements of the electromagnetic switching mechanism 2 on the movable linkage 6, and improves transmission reliability.

[0065] Through the above structural design, the movable linkage 6 rotates around the rotating shaft 7. With the positions of the motor gear 13 and the transmission group unchanged, the meshing state of the motor gear 13 and the two transmission groups is switched to form a structure that is in contact and disengaged at the same time. This can be controlled simultaneously by the electromagnetic switching mechanism 2, which improves the synchronicity of the state switching of the two transmission groups.

[0066] Example 3:

[0067] like Figure 1-6 As shown, based on the above embodiment 2, the electromagnetic switching mechanism 2 includes a magnet 14 and a coil electromagnet 15. The magnet 14 is installed in the magnet seat 15 at the end of the upper support arm 8, and the coil electromagnet 15 is installed on the top plate of the support frame 5. When the coil electromagnet 15 is energized, it attracts or repels the magnet 14.

[0068] The working principle and beneficial effects of the above technical solution are as follows:

[0069] The electromagnetic switching mechanism 2 adopts the principle of magnetic force. By changing the energizing direction of the coil electromagnet 15, a magnetic field with opposite magnetic properties is generated, which generates an attractive or repulsive force on the magnet 14, driving the magnet 14 to move closer to or away from the coil electromagnet 15, thereby driving the rotating shaft 7 to rotate, causing the movable linkage frame 6 to rotate accordingly. A coil spring can be installed on the rotating shaft 7 to assist in the stable rotation of the rotating shaft 7.

[0070] Example 4:

[0071] Based on the above embodiment 1, motor 1 is configured as a carbon brush motor.

[0072] The working principle and beneficial effects of the above technical solution are as follows:

[0073] Motor stall refers to the phenomenon where the motor continues to output torque even when its speed is zero, usually caused by mechanical failure or human error. In this situation, excessive motor load, mechanical failure in the driven component, or bearing damage can cause the motor to fail to start or stop. When a motor is stalled, the power factor is extremely low, and the current may reach 5-12 times the rated current, or even higher. Prolonged stalling can damage the motor. Replacing the stepper motor with a brush motor allows for better reading of stall data and monitoring of the motor's stall status.

[0074] Example 5:

[0075] like Figure 1-6As shown, based on the above embodiment 1, the support frame 5 includes three support platforms. The first support platform 16 is used to connect the coil electromagnet 15 and the peristaltic pump 3. The second support platform 17 is used to connect the motor 1, the first transmission group and the second transmission group. The third support platform 18 is used to connect the lead screw 4. The movable linkage frame 6 is connected between the first support platform 16 and the second support platform 17, and the upper support arm 8 is located above the first support platform 16.

[0076] The working principle and beneficial effects of the above technical solution are as follows:

[0077] The support frame 5 is set as a three-layer support platform, which separates the electromagnetic switching mechanism 2, the transmission group, the peristaltic pump 3 and the lead screw 4, and provides sufficient support.

[0078] Example 6:

[0079] like Figure 1-6 As shown, based on the above embodiment 1, the first transmission group is configured as a gear group, which includes: a first double gear 21, a second double gear 22, a third double gear 23, a fourth double gear 24, and a peristaltic pump shaft gear 25. The large gear of the first double gear 21 meshes with the peristaltic pump connecting gear 11, the small gear of the first double gear 21 meshes with the large gear of the second double gear 22, the small gear of the second double gear 22 meshes with the large gear of the third double gear 23, the small gear of the third double gear 23 meshes with the large gear of the fourth double gear 24, and the small gear of the fourth double gear 24 meshes with the peristaltic pump shaft gear 25. The peristaltic pump shaft gear 25 is mounted on the drive shaft of the peristaltic pump 3.

[0080] The second transmission group is configured as a gear group, which includes: a fifth double gear 26, a sixth double gear 27, a seventh double gear 28, and a lead screw shaft gear 29. The large gear of the fifth double gear 26 meshes with the lead screw connecting gear 12, the small gear of the fifth double gear 26 meshes with the large gear of the sixth double gear 27, the small gear of the sixth double gear 27 meshes with the large gear of the seventh double gear 28, the small gear of the seventh double gear 28 is located below the second support platform 17 and meshes with the lead screw shaft gear 29, and the lead screw shaft gear 29 is mounted on the drive shaft of the lead screw 4.

[0081] The dimensions of the double gear are less than 25mm × 22mm × 11mm.

[0082] The working principle and beneficial effects of the above technical solution are as follows:

[0083] Both the first and second transmission groups are gear sets, which include multiple double gears connected in sequence. Using double gears for transmission has strong load-bearing capacity, uniform contact stress distribution, and is less prone to problems such as broken or slipped teeth. The contact between adjacent teeth of the double gears is continuous, and there is no slippage between the tooth surfaces, which can achieve better power transmission, improve transmission efficiency, and reduce vibration and noise generation, making the transmission smoother.

[0084] Example 7:

[0085] like Figure 7 As shown, based on the above embodiment 1, the contact surface between the outer shell 31 of the coil electromagnet 15 and the magnet 14 is set as a circular surface. Multiple telescopic buffer pads 32 are connected to the outer shell 31, and the multiple buffer pads 32 are evenly arranged along the circumference of the outer shell 31. The buffer pads 32 are in contact with the end face of the magnet 14 to reduce the impact on the outer shell 31.

[0086] The outer casing 31 has multiple buffer grooves 33 corresponding to the buffer pad 32. The buffer pad 32 slides along the inner wall of the buffer groove 33 without coming off.

[0087] The working principle and beneficial effects of the above technical solution are as follows:

[0088] The coil electromagnet 15 is installed inside the housing 31 and mounted on the support frame 5 via the housing 31. When the coil electromagnet 15 attracts the magnet 14 to move, the magnet 14 will impact when it comes into contact with the housing 1, causing vibration of the housing 31 and the inside of the mechanism, generating noise. Therefore, by setting multiple buffer pads 32, when the magnet 14 moves towards the housing 31, after the magnet 14 comes into contact with the buffer pad 32, it squeezes the buffer pad 32 and causes it to shrink into the buffer groove 33, dissipating the kinetic energy of the magnet 14 until the magnet 14 is in contact with the surface of the housing 31, reducing the impact and noise on the housing 31.

[0089] Example 8:

[0090] like Figure 8-12 As shown, based on the above embodiment 7, an auxiliary buffer assembly is provided in the buffer slot 33. The auxiliary buffer assembly includes:

[0091] The first folding plate 34 and the second folding plate 35 are hinged to one side of the buffer pad 32 located in the buffer groove 33. The two first folding plates 34 and the two second folding plates 35 are symmetrically arranged, and the two second folding plates 35 are located between the two first folding plates 34. The second folding plates 35 are perpendicular to the buffer pad 32, and the first folding plates 34 are inclined to the buffer pad 32. The end of the first folding plate 34 is slidably connected to the side of the second folding plate 35. The hinge points of the first folding plate 34 and the second folding plate 35 with the buffer pad 32 are provided with elastic reset members. The elastic reset key can be set as a coil spring.

[0092] Folding spring 36, the folding spring 36 is connected between two second folding plates 35, and the middle part of the folding spring 36 can be bent towards the bottom of the buffer groove 33;

[0093] Two baffles 37 are connected to the bottom of the buffer groove 33, and the ends of the baffles 37 abut against the side of the first folding plate 34.

[0094] The working principle and beneficial effects of the above technical solution are as follows:

[0095] The surface of the buffer pad 32 is provided with a flexible rubber pad, and an auxiliary buffer assembly is provided on the back of the buffer pad 32. After the buffer pad 32 is subjected to the pressure of the magnet 14, it is pushed to slide into the buffer groove 33. The first folded plate 34 on the buffer pad 32 contacts the baffle 37 and rotates inward under the squeezing force of the baffle 37. The end of the first folded plate 34 is slidably disposed on the side of the second folded plate 35, pushing the second folded plate 35 to rotate inward as well. When the first folded plate 34 and the second folded plate 35 rotate, they need to overcome the elastic force of the elastic reset member to achieve further buffering and shock absorption. A folding spring piece 36 is connected between the two second folded plates 35. When the two second folded plates 35 rotate, the ends squeeze the folding spring piece 36 and deform it. The elastic force of the folding spring piece 36 achieves further buffering and shock absorption. Through the above structural design, the pressure on the buffer pad 32 is transmitted to the first folding plate 34 and the second folding plate 35, forming a gap between the buffer pad 32 and the bottom of the buffer groove 33 to avoid large-area direct impact. At the same time, the impact is further dissipated by the elastic reset member and the folding spring 36. The buffering performance is improved by rigid isolation and flexible energy absorption. Moreover, compared with the complete use of rubber pads for buffering, the thickness of the flexible rubber pad on the buffer pad 32 is set to be thinner, which ensures the buffering performance while avoiding the displacement of the magnetic block 14 caused by uneven deformation of the flexible rubber pad, and ensuring the accurate movement of the movable linkage frame 6.

[0096] Example 9:

[0097] like Figure 8-12 As shown, based on the above embodiment 8, the second folding plate 35 is provided with a limiting unit, which includes:

[0098] The guide chute 38 is located on the side of the second folding plate 35 near the first folding plate 34. The bottom of the guide chute 38 is provided with a limiting conical groove 41 on the side away from the buffer pad 32 and in the middle.

[0099] The guide slider 39 is slidably connected in the guide groove 30 and is hinged to the first folding plate 34. The guide slider 39 has a slide 42 through both ends in the middle of its middle part, and a tapered through hole 45 is opened through the side of the guide slider 39 near the bottom of the guide groove 38.

[0100] The limiting slide post 43 is slidably connected to the slide rail 42, and the length of the limiting slide post 43 is greater than the length of the slide rail 42. A receiving groove 44 is provided on the side of the limiting slide post 43 near the bottom of the guide slide groove 38.

[0101] A conical locking block 46 is slidably connected in the receiving groove 44. An electrically controlled reset component 47 is connected to the bottom of the receiving groove 44 at the end of the conical locking block 46. When the conical locking block 46 engages with the conical through hole 45 and the limiting conical groove 41, the guide slider 39 is locked and limited.

[0102] The electronically controlled reset component 47 can be configured as a shape memory alloy that contracts when energized and has elastic reset performance when de-energized, or it can be configured as a combination of an electromagnetic block and a magnetic block that attract each other when energized, with a spring connecting the two, and the electromagnetic block and the magnetic block are respectively set at the bottom of the receiving groove 44 and the end of the conical block 46.

[0103] The working principle and beneficial effects of the above technical solution are as follows:

[0104] When the buffer pad 32 is impacted by the magnet 14, the buffer is cushioned by the auxiliary buffer assembly. The buffer pad 32 is completely housed in the buffer groove 33, and the magnet 14 contacts the circular surface of the outer shell 31, ensuring that the position of the magnet 14 is the same each time. Due to the rapid movement of the magnet 14, the buffer pad 32 will continue to move into the buffer groove 33 under the impact force. After the magnet 14 stops moving after contacting the circular surface of the outer shell 31, the buffer pad 32 will still move a small distance under the action of inertia, separate from the magnet 14, and then reset. During the reset process, a certain reverse force will be generated on the magnet 14, causing the magnet 14 to loosen from the outer shell 31, affecting the accuracy of the transmission. Therefore, a limiting unit is set up. When the magnet 14 is away from the coil electromagnet 15, the guide slider 39 is located at the end of the guide groove 38 away from the buffer pad 32. At this time, one end of the limiting slide post 43 is in contact with the side wall of the guide groove 38, and the other end extends out of the guide slider 39. The receiving groove 44 is directly opposite the conical through hole 45 and the limiting conical groove 41. The conical locking block 46 is engaged in the conical through hole 45 and the limiting conical groove 41, locking the guide slider 39 and locking the positions of the first folding plate 34 and the second folding plate 35. The buffer pad 32 is in the extended state. When the buffer pad 32 is compressed, the first folding plate 34 and the second folding plate 35 rotate relative to each other. The conical locking block 46 is forced to move out of the conical through hole 45, and the guide slider 39 slides in the guide groove 38 and slides to the other end of the guide groove 38 under the action of inertia. At this time, the magnet 14 is separated from the outer shell 31, the limiting slide post 43 contacts the side wall of the guide slide groove 30 and slides relative to the guide slider 39, so that the other end extends out of the guide slider 39, and the conical block 46 is offset from the conical through hole 45; then, under the action of elastic force, the first folding plate 34 and the second folding plate 35 rotate relative to each other and reset, the guide slider 39 slides in the opposite direction until the receiving groove 44 is aligned with the conical through hole 45 and the limiting conical groove 41 in the middle, locking the guide slider 39 again. At this time, the buffer pad 32 is in a contracted state, and the buffer pad 32 is aligned with or slightly concave relative to the circular surface of the outer shell 31; when the coil electromagnet 15 pushes the magnet 14, the electronically controlled reset component 47 is energized at the same time, and the conical block 46 is stored in the receiving groove 44, so that the first folding plate 34 and the second folding plate 35 are quickly reset.

[0105] Through the above structural design, the position of the buffer pad 32 in both extended and retracted states is locked. In the extended state, the position and angle of the first folding plate 34 and the second folding plate 35 are kept consistent, ensuring consistent shock absorption performance. In the retracted state, the buffer pad 32 can be locked to a preset position when the magnet 14 is separated from the outer shell 31, preventing the buffer pad 32 from rebounding and impacting the magnet 14 and the movable connecting rod 6. This ensures that the circular surface of the buffer pad 32 is aligned with or slightly concave with the outer shell 31, preventing the magnet 14 from loosening after being subjected to a reverse impact, ensuring the magnet 14 stops smoothly, and improving the accuracy of transmission.
