Description

Technical Field

[0001] This invention relates to the technical field of oiling, and more particularly to an automatic oiling device for motor manufacturing and assembly. Background Technology

[0002] In the motor manufacturing process, equipment that automatically adds lubricant to motor components is needed to improve production efficiency, reduce errors and inconsistencies caused by manual operation, ensure the quality and reliability of motor assembly, and reduce maintenance costs and failure rates.

[0003] In existing motor lubrication technology, the motor needs to rotate continuously at a single lubrication point to ensure uniform distribution of lubricating oil. This causes the lubricating oil to tend to move outward due to centrifugal force. This not only makes it difficult for the lubricating oil to penetrate into the parts that need lubrication, but also easily causes the lubricating oil to form an adhesion layer on the surface instead of penetrating into the interior of the parts. This surface adhesion layer cannot effectively reduce friction and wear, thus affecting the quality of the final product. Summary of the Invention

[0004] In order to overcome the disadvantage that lubricating oil is difficult to penetrate into the internal parts that need lubrication due to centrifugal force, the present invention provides an automatic oiling device for motor production and assembly.

[0005] An automatic oiling device for motor production and assembly includes a housing with several sets of electric wheels rotatably connected to the housing. Each set of electric wheels is fitted with a chain. The device is characterized by connecting rods evenly spaced and fixed to the chains, which are rotatably connected to mounting frames. The mounting frames have insertion holes for inserting motors. A pressure injection pipe for injecting lubricating oil passes through the upper part of the housing and is connected to at least one telescopic injection frame. The telescopic injection frame is connected to at least two sets of oil spray pipes at equal intervals. A mounting rod is fixedly connected to the housing below the mounting frame, and at least one guide block is fixedly connected to the mounting rod. The guide block has an inclined surface that presses against the mounting frame.

[0006] Preferably, the mounting bracket is provided with equally spaced protrusions along the circumference. The mounting bracket is engaged with the inclined surfaces of the guide blocks by the protrusions. The number of sets of upper oil injection pipes is the same as the number of protrusions of the mounting bracket, and the number of guide blocks is one less than the number of protrusions of the mounting bracket.

[0007] Preferably, the number of telescopic injection racks and mounting rods are the same as and correspond to the number of chains.

[0008] Preferably, the system also includes photoelectric sensor movers symmetrically distributed along each set of upper oil injection pipes. The photoelectric sensor movers are fixedly connected to adjacent telescopic injection frames. Each upper oil injection pipe is fixedly connected to a mounting block. The same first spring is fixedly connected between adjacent mounting blocks and between the photoelectric sensor movers and adjacent mounting blocks.

[0009] Preferably, the device also includes a locking block corresponding to the mounting bracket. The locking block is slidably connected to the corresponding mounting bracket. The locking block and the adjacent connecting rod are engaged by mutually matching curved surfaces. A second spring is fixedly connected between the locking block and the corresponding mounting bracket.

[0010] Preferably, it also includes L-shaped fixing rods with the same number as the mounting bracket protrusions. Each L-shaped fixing rod is fixedly connected to each photoelectric sensor mover on one side. The L-shaped fixing rod is slidably connected to a locking rod. A tension spring is fixed between the locking rod and the adjacent L-shaped fixing rod. The mounting rod has equally spaced locking holes on the side near the locking rod. The locking rod is inserted into the adjacent locking hole.

[0011] Preferably, the spacing between adjacent mounting holes of the mounting rod is equal to the spacing between adjacent mounting brackets.

[0012] Preferably, the end face of the clamping rod near the clamping hole is set as a spherical surface, and the clamping rod is pressed and engaged with the mounting rod through the spherical surface at the end.

[0013] Preferably, the guide block is provided with multiple equally spaced protrusions.

[0014] The beneficial effects of this invention are:

[0015] This invention automatically applies oil to a stationary motor via each oiling nozzle, and then uses a chain to intermittently rotate clockwise, allowing the remaining oiling nozzles to sequentially apply oil to the remaining parts of the stationary motor, thus completing the oiling of the entire motor. This avoids the centrifugal force generated by the motor's rotation during oiling, which would prevent the lubricating oil from penetrating the internal parts that need lubrication. Furthermore, each oiling nozzle can simultaneously apply oil to the motor below, ensuring continuous oiling and thus guaranteeing a certain level of oiling efficiency.

[0016] This invention allows a motor to be inserted at any number of mounting brackets, thereby adjusting the spacing between adjacent motors as needed. This, in turn, allows control over the motor's start-up time, enabling adjustment of the required lubricant penetration time based on the specific process. In this way, both oiling efficiency and sufficient time for lubricant penetration can be ensured.

[0017] This invention uses a photoelectric sensor to autonomously adjust and position itself to the edge of the motor. During the positioning process, the mounting block simultaneously pushes and pulls the soft oil spray pipe on it. With the balanced assistance of three adjacent first springs, the oil spray pipe is autonomously positioned directly above the motor, ensuring the effectiveness of oil application.

[0018] This invention uses the locking action of the connecting rod and the locking block to prevent the mounting frame from rotating arbitrarily during the transmission process, thereby preventing the motor from rotating arbitrarily. This avoids the lubricated side of the motor rotating from top to bottom, causing the lubricant to drip downwards, and also prevents the subsequent steps of sequentially flipping and applying lubricant to specific areas from becoming disordered and failing.

[0019] This invention uses a clamp to position the oil spray nozzle and fix its position, preventing the oil spray nozzle from changing its spray position due to the arbitrary extension and retraction of the telescopic injection frame during oil application.

[0020] By setting protruding strips, the mounting bracket can bounce up and down over the protruding strips before the motor rotates, achieving a micro-vibration effect. This helps the lubricating oil on the motor to penetrate further into the interior and prevents the lubricating oil from adhering to the surface. Attached Figure Description

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] Example 1: An automatic oiling device for motor production and assembly, such as... Figure 1 , Figure 2 and Figure 3 As shown, the device includes a housing 1. Inside the housing 1, four sets of electric wheels 2 are symmetrically distributed along the left and right sides. A chain 3 is installed between the two electric wheels 2 in the front set. Chains 3 can be installed between the remaining sets of electric wheels 2 as needed. Multiple equally spaced connecting rods 4 are fixedly connected to the chains 3 circumferentially. A mounting bracket 5 is rotatably connected to the connecting rods 4. The mounting bracket 5 has four equally spaced protrusions circumferentially arranged, making the connecting rods 4 form a cross shape. The mounting bracket 5 has a socket for inserting a motor 101. A device for injection is inserted through the upper part of the housing 1. The injection pipe 6 for lubricating oil is connected to an external injection machine. A telescopic injection frame 7 is connected to the front of the injection pipe 6. The number of telescopic injection frames 7 can be adjusted according to the number of chains 3 installed. Four sets of flexible oil spray pipes 8 are connected at equal intervals on the telescopic injection frame 7. A mounting rod 9 is fixed to the upper front of the housing 1. The number of mounting rods 9 can be adjusted according to the number of chains 3 installed. Three guide blocks 10 are fixed to the top side of the mounting rod 9 near the top of the oil spray pipes 8. The guide blocks 10 have inclined surfaces that engage with the protruding rods of the mounting frame 5. Figure 8 As shown, the guide block 10 is provided with three equally spaced protrusions 19.

[0032] First, insert each motor 101 into the corresponding mounting bracket 5 at equal intervals. Then, inject lubricating oil into the telescopic injection bracket 7 through the injection pipe 6. Next, apply lubricating oil to one-quarter of the surface of the lower motor 101 through the oil spray pipe 8. Then, the injection machine controls the injection pipe 6 to stop oiling. At the same time, the electric wheel 2 automatically controls the chain 3 to drive the connecting rod 4, mounting bracket 5, and motor 101 to start intermittent clockwise transmission. The mounting bracket 5 with the motor 101 inserted moves to contact the inclined surface of the adjacent guide block 10. Under the squeezing action of the inclined surface of the guide block 10, the motor 101 is inserted... The mounting bracket 5 with motor 101 rotates clockwise, thereby causing motor 101 to flip. When the mounting bracket 5 rotates 90 degrees, it disengages from the adjacent guide block 10. The mounting bracket 5 drives motor 101, which has been flipped 90 degrees, to continue transmission to below the oil spray pipe 8. At this point, the chain 3 stops transmission, and oil is applied to the side of motor 101 after it has been flipped 90 degrees through the oil spray pipe 8. The chain 3 continues transmission, and motor 101 continues to flip 90 degrees clockwise. This process is repeated. During the clockwise transmission, all motors 101 can complete automatic oiling for one revolution.

[0033] In summary, this invention automatically applies oil to a stationary motor 101 via each oiling nozzle 8, and then uses the intermittent clockwise transmission of the chain 3 to cause all motors 101 to shift clockwise and automatically rotate during the shift. This allows the remaining oiling nozzles 8 to sequentially apply oil to the remaining parts of the stationary motors 101, thus completing the oiling of the entire motor 101. This avoids the centrifugal force generated by the rotation of the motor 101 during oiling, which would prevent the lubricating oil from penetrating to the internal parts that need lubrication. Moreover, each oiling nozzle 8 can simultaneously apply oil to the motors 101 below, thus ensuring the continuity of oiling and guaranteeing a certain level of oiling efficiency.

[0034] Furthermore, the present invention allows for the insertion of a motor 101 at any number of mounting brackets 5, thereby adjusting the spacing between adjacent motors 101 as needed. This allows for the control of the starting time of the motor 101's rotation, enabling the adjustment of the required lubricating oil penetration time based on the specific process of the motor 101. In this way, both oiling efficiency and sufficient time for lubricating oil penetration can be ensured.

[0035] The present invention provides equidistant protrusions 19 on each guide block 10, so that the mounting bracket 5 can bounce up and down over the protrusions 19 before driving the motor 101 to rotate, achieving a micro-vibration effect. This helps the lubricating oil on the motor 101 to further penetrate into the interior and prevents the lubricating oil from adhering to the surface.

[0036] Example 2: Based on Example 1, such as Figure 4 The system also includes photoelectric sensor movers 11 symmetrically distributed along the front and back of each set of upper oil injection pipes 8. The photoelectric sensor movers 11 are fixedly connected to the adjacent telescopic liquid injection racks 7. Each upper oil injection pipe 8 has a mounting block 12 fixedly connected to its lower part. The same first spring 13 is fixedly connected between adjacent mounting blocks 12 and between the photoelectric sensor movers 11 and adjacent mounting blocks 12.

[0037] When the motor 101 is inserted into the mounting bracket 5, the insertion depth of each motor 101 may be different, which may cause the upper oil injection pipe 8 to not be positioned directly above the motor 101 when the motor 101 is delivered to the lower oil injection pipe 8. Therefore, the photoelectric sensor movers 11 on the front and rear sides detect the edge positions of the front and rear sides of the lower motor 101 respectively. Based on the detected positions, the movers autonomously adjust and position themselves to the edge position of the motor 101. During the positioning process, the photoelectric sensor movers 11 pull the mounting block 12 to move synchronously through the first spring 13 on it. The mounting block 12 then pushes and pulls the soft upper oil injection pipe 8 on it synchronously. Under the balanced assistance of the three adjacent first springs 13, the upper oil injection pipe 8 is autonomously positioned directly above the motor 101, ensuring the effectiveness of oil application.

[0038] like Figure 5 and Figure 6As shown, it also includes a locking block 14 corresponding to the mounting bracket 5. The locking block 14 is slidably connected to the corresponding mounting bracket 5. The locking block 14 and the adjacent connecting rod 4 are engaged by mutually concave and convex curved surfaces. A second spring 15 is fixedly connected between the locking block 14 and the corresponding mounting bracket 5.

[0039] The engagement between the connecting rod 4 and the locking block 14 prevents the mounting frame 5 from rotating arbitrarily during transport, thus preventing the motor 101 from rotating arbitrarily. This avoids the lubricated side of the motor 101 from rotating from top to bottom, causing the lubricant to drip downwards, and also prevents the subsequent sequential flipping and partial lubrication steps from becoming disordered and failing. When the mounting frame 5 is flipped by the pressure of the guide block 10, the mounting frame 5 drives the locking block 14 inside to rotate. During the rotation, the locking block 14 is pressed by the connecting rod 4 and slides towards the side that compresses the second spring 15. After the flip is complete, the second spring 15 resets and pushes the locking block 14 to slide in the opposite direction again until it engages with the connecting rod 4.

[0040] like Figure 7 As shown, it also includes four L-shaped fixing rods 16, each L-shaped fixing rod 16 being fixedly connected to each photoelectric sensor mover 11 on the rear side. The lower part of the L-shaped fixing rod 16 is slidably connected to a locking rod 17 in the front-rear direction. The front end face of the locking rod 17 is set as a spherical surface. The locking rod 17 is pressed and engaged with the mounting rod 9 through the spherical surface at the end. A tension spring 18 is fixedly connected between the locking rod 17 and the adjacent L-shaped fixing rod 16. The rear side of the mounting rod 9 has equally spaced locking holes. The distance between adjacent locking holes of the mounting rod 9 is equal to the distance between adjacent mounting brackets 5. The locking rod 17 is inserted into the adjacent locking hole.

[0041] After adjusting the spacing between adjacent motors 101, the spacing between adjacent oil injection pipes 8 needs to be adjusted by pushing and pulling the telescopic injection frame 7. During the adjustment process, the telescopic injection frame 7 drives the locking rod 17 to move synchronously through the L-shaped fixing rod 16 on it. When the locking rod 17 disengages from the locking hole, the mounting rod 9 presses the locking rod 17 to slide towards the side of the tension spring 18. When the locking rod 17 is aligned with the locking hole, the tension spring 18 resets and drives the locking rod 17 to insert into the corresponding locking hole, thereby achieving the effect of adjusting and fixing the position of the upper oil injection pipe 8.

Any equivalent structural or procedural transformations made based on the content of the present invention specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
