Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of oiling, and particularly relates to an automatic oiling device for motor production and assembly. BACKGROUND

[0002] In the motor production process, a device for automatically adding lubricant to motor parts 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 the existing motor oiling technology, the motor needs to be continuously rotated at a single oiling point to ensure uniform distribution of the lubricating oil. This causes the lubricating oil to move outward due to centrifugal force, which not only makes it difficult for the lubricating oil to penetrate the internal parts that need to be lubricated, but also easily causes the lubricating oil to form an attached layer on the surface rather than penetrating the internal parts. This surface attached layer cannot effectively reduce friction and wear, thereby affecting the quality of the final product. SUMMARY

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

[0005] An automatic oiling device for motor production and assembly, comprising a box body, a plurality of groups of electric wheels are rotationally connected to the box body, each group of electric wheels is sleeved with a chain, characterized in that a plurality of connecting rods are fixedly connected to the chain at equal intervals, the connecting rods are rotationally connected with mounting racks, the mounting racks are provided with insertion holes for inserting the motor, a pressure injection pipe for injecting lubricating oil is connected to the upper part of the box body, the pressure injection pipe is connected with at least one telescopic liquid injection frame, the telescopic liquid injection frame is connected with at least two groups of oiling spray pipes at equal intervals, a mounting rod is fixedly connected to the lower part of the mounting rack in the box body, at least one guide block is fixedly connected to the mounting rod, and a slope is arranged on the guide block and in extrusion fit with the mounting rack.

[0006] As a preferred, the mounting rack is provided with a plurality of convex rods distributed at equal intervals in the circumferential direction, the mounting rack is in extrusion fit with the slope of the guide block through the convex rods, the number of groups of oiling spray pipes is the same as the number of convex rods of the mounting rack, and the number of guide blocks is one less than the number of convex rods of the mounting rack.

[0007] As a preferred, the number of telescopic liquid injection frames and the number of mounting rods are the same and correspond to the number of chains.

[0008] As a preferred, the light-sensing mobile device is symmetrically distributed along each group of oiling spray pipes, the light-sensing mobile device is fixedly connected to the adjacent telescopic liquid injection frame, each oiling spray pipe is fixedly connected with a mounting block, and the same first spring is fixedly connected between adjacent mounting blocks and between the light-sensing mobile device and adjacent mounting blocks.

[0009] Preferably, a clamping block corresponding to the mounting frame is further included, the clamping block is slidably connected to the corresponding mounting frame, the clamping block and the adjacent connecting rod are clamped by mutually concave and convex curved surfaces, and a second spring is fixed between the clamping block and the corresponding mounting frame.

[0010] Preferably, it also includes L-shaped fixing rods with the same number as the protruding rods of the mounting frame, each L-shaped fixing rod is respectively fixed to each photoelectric sensor mover on one side, the L-shaped fixing rod is slidably connected to a clamping rod, and a tension spring is fixed between the clamping rod and the adjacent L-shaped fixing rod, and the side of the mounting rod close to the clamping rod is provided with equally spaced clamping holes, and the clamping rod is inserted into the adjacent clamping holes.

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

[0012] Preferably, the end surface of the clamping rod close to the clamping hole is set to be a spherical surface, and the clamping rod is squeezed and fitted with the installation rod through the spherical surface at the end.

[0013] Preferably, the guide block is provided with a plurality of convex strips distributed at equal intervals.

[0014] The beneficial effects of the present invention are: The present invention uses each oiling nozzle to automatically oil a part of the stationary motor, and then uses the chain to intermittently drive clockwise, so that the remaining oiling nozzles oil the remaining parts of the stationary motor in turn, so as to complete the oiling of the entire motor, avoiding the centrifugal force generated by the rotation of the motor during oiling, which makes it difficult for the lubricating oil to penetrate into the internal parts that need lubrication. Moreover, each oiling nozzle can oil the motor below at the same time, ensuring the continuity of oiling, thereby ensuring a certain oiling efficiency.

[0015] The present invention can insert a motor every any number of mounting racks, so that the spacing between adjacent motors can be adjusted as needed, and then the time when the motor starts to flip can be regulated to adjust the time required for the lubricating oil to penetrate the motor according to the specific process. In this way, it can take into account the oiling efficiency and ensure that the lubricating oil has sufficient time to penetrate.

[0016] The present invention uses a photoelectric sensor mover to autonomously adjust and position itself to the edge of the motor. During the positioning process, the mounting block synchronously pushes and pulls the soft oiling nozzle thereon. With the balanced assistance of the three adjacent first springs, the oiling nozzle is autonomously positioned directly above the motor, ensuring the effectiveness of oiling.

[0017] The present invention prevents the mounting frame from rotating randomly during the transmission process by means of the engagement of the connecting rod and the clamping block, thereby preventing the motor from rotating randomly. This prevents the lubricating oil-coated side of the motor from rotating from the top to the bottom, causing the lubricating oil to drip downward, and also prevents the subsequent steps of turning over and applying oil locally from being disordered and ineffective.

[0018] The application positions the oiling spray pipe to the position through the clamping rod, and fixes the position of the oiling spray pipe through the clamping rod, so that the oiling spray pipe is prevented from changing the oiling position due to the random expansion and contraction of the telescopic liquid injection frame during oiling.

[0019] The convex strip is arranged, so that the mounting frame can first pass through the convex strip up and down and achieve the effect of micro-vibration before the mounting frame is driven to overturn, the lubricating oil on the motor is further penetrated into the interior, and the lubricating oil is prevented from adhering to the surface.

DETAILED DESCRIPTION

[0029] The application will be further described in combination with the drawings and specific embodiments.

[0030] Example 1: an automatic oiling device for motor production and assembly, as shown in Figure 1 , Figure 2 andFigure 3 As shown, including the box 1, the inside of the box 1 is rotatably connected with four groups of electric wheels 2 along the box 1 left-right symmetry distribution, a chain 3 is installed between the left and right two electric wheels 2 of the front side, the rest of each group of electric wheels 2 can be installed according to the needs of chain 3, the chain 3 is circumferentially fixed with a plurality of equidistantly distributed connecting rods 4, the connecting rod 4 is rotatably connected with the mounting bracket 5, the mounting bracket 5 is circumferentially provided with four equidistantly distributed convex rods, so that the connecting rod 4 is in the shape of a cross, the mounting bracket 5 is provided with a hole for inserting the motor 101, the upper part of the box 1 is provided with a pressure injection pipe 6 for injecting lubricating oil, the pressure injection pipe 6 is communicated with the external pressure injection machine, the front side of the pressure injection pipe 6 is communicated with an extension liquid injection frame 7, according to the number of chain 3 installation, can also be adapted to increase or decrease the corresponding extension liquid injection frame 7, the extension liquid injection frame 7 is equidistantly communicated with four groups of soft oil injection pipes 8, the inside of the box 1 is fixed with an installation rod 9, according to the number of chain 3 installation, can also be adapted to increase or decrease the corresponding installation rod 9, the installation rod 9 is fixed with three guide blocks 10 near the top side of the oil injection pipe 8, the guide block 10 is provided with a slope which is in extrusion fit with the convex rod of the mounting bracket 5, as shown in Figure 8 As shown, the guide block 10 is provided with three equidistantly distributed convex strips 19.

[0031] First, the motors 101 are inserted into the corresponding mounting bracket 5 holes at equal intervals, then the lubricating oil is injected into the extension liquid injection frame 7 through the pressure injection pipe 6, and then the lubricating oil is sprayed onto the lower quarter of the motor 101 through the oil injection pipe 8, then the pressure injection machine controls the pressure injection pipe 6 to stop oiling, and the electric wheel 2 automatically controls the chain 3 to drive the connecting rod 4, the mounting bracket 5 and the motor 101 to start intermittent clockwise transmission, the mounting bracket 5 with the motor 101 moves to contact with the slope of the adjacent guide block 10, under the extrusion of the guide block 10 slope, the mounting bracket 5 with the motor 101 rotates clockwise, thereby driving the motor 101 to flip, when the mounting bracket 5 rotates 90 degrees and is separated from the adjacent guide block 10, the mounting bracket 5 drives the motor 101 which has been flipped 90 degrees to continue transmission to the lower side of the oil injection pipe 8, the chain 3 stops transmission, and then the oil injection pipe 8 sprays oil on the side of the motor 101 which has been flipped 90 degrees, the chain 3 continues to transmit, and the motor 101 continues to flip 90 degrees clockwise, so as to repeat the above process, during the clockwise transmission process, all the motors 101 can complete automatic oiling.

[0032] In summary, the present application automatically oils each stationary motor 101 in part through each oiling nozzle 8, and then makes all the motors 101 move clockwise and automatically turn over in the process of moving through the intermittent clockwise transmission of the chain 3, so that the remaining oiling nozzles 8 in turn oil the remaining parts of the stationary motor 101 in turn, and then complete the oiling of the entire motor 101, thus avoiding the centrifugal force generated by the rotation of the motor 101 during oiling, which makes it difficult for the lubricating oil to penetrate into the internal parts that need to be lubricated, and each oiling nozzle 8 can oil the motor 101 below at the same time, thus ensuring the continuity of the oiling, thereby ensuring a certain oiling efficiency.

[0033] In addition, the present application can insert a motor 101 every arbitrary number of mounting racks 5, so that the spacing between adjacent motors 101 can be adjusted as needed, and then the time when the motor 101 starts to turn over can be controlled, so that the time required for the lubricating oil to penetrate can be adjusted according to the specific process of the motor 101, so that both the oiling efficiency and the time for the lubricating oil to penetrate can be ensured.

[0034] The present application provides equal-interval protrusions 19 on each guide block 10, so that the mounting rack 5 can first pass through the protrusions 19 up and down to achieve the effect of micro-vibration before driving the motor 101 to turn over, which is beneficial to the further penetration of the lubricating oil on the motor 101 into the interior, and avoids the lubricating oil adhering to the surface.

[0035] Example 2: based on example 1, as Figure 4 The present application also includes a photoelectric sensing mover 11 symmetrically distributed along each group of oiling nozzles 8, the photoelectric sensing mover 11 is fixedly connected with the adjacent telescopic liquid injection rack 7, the lower part of each oiling nozzle 8 is fixedly connected with a mounting block 12, and the same first spring 13 is fixedly connected between adjacent mounting blocks 12 and between the photoelectric sensing mover 11 and the adjacent mounting block 12.

[0036] When the motor 101 is inserted into the mounting rack 5, the depth of each motor 101 inserted may be different, which causes the oiling nozzle 8 to not be located directly above the motor 101 when the motor 101 is conveyed below the oiling nozzle 8, therefore, the photoelectric sensing mover 11 on the front and back sides detects the edge positions of the motor 101 on the front and back sides below, and then automatically adjusts the edge position of the motor 101 to be positioned, in the process of positioning, the photoelectric sensing mover 11 pulls the mounting block 12 to move synchronously through the first spring 13 thereon, and the mounting block 12 in turn pushes and pulls the soft oiling nozzle 8 thereon, under the balanced assistance of the adjacent three first springs 13, so that the oiling nozzle 8 is automatically positioned directly above the motor 101, and the effectiveness of the oiling is ensured.

[0037] As Figure 5 and Figure 6As shown, the device also comprises a clamping block 14 corresponding to the mounting rack 5, the clamping block 14 being slidingly connected in the corresponding mounting rack 5, the clamping block 14 and the adjacent connecting rod 4 being engaged by mutually matching curved surfaces, and the clamping block 14 and the corresponding mounting rack 5 being fixedly connected by a second spring 15.

[0038] Through the clamping action of the connecting rod 4 and the clamping block 14, the mounting rack 5 cannot be randomly rotated during the conveying process, so that the motor 101 cannot be randomly rotated, thereby avoiding the situation that the side of the motor 101 with good lubricating oil is rotated from the top to the bottom, causing the lubricating oil to drip downward, and avoiding the situation that the subsequent sequential oiling steps are disordered and fail, and when the mounting rack 5 is turned over under the extrusion action of the guide block 10, the mounting rack 5 drives the clamping block 14 inside to rotate, and in the process of rotation, the clamping block 14 slides to the side where the second spring 15 is compressed under the extrusion action of the connecting rod 4, and after the turning over is completed, the second spring 15 resets to push the clamping block 14 to slide again in the opposite direction to be clamped with the connecting rod 4.

[0039] As shown, Figure 7 The device also comprises four L-shaped fixed rods 16, each of which is fixedly connected to each of the rear photoelectric sensing movers 11, the lower part of the L-shaped fixed rod 16 being slidingly connected in the front-rear direction by a clamping rod 17, the front end face of the clamping rod 17 being provided as a spherical surface, the clamping rod 17 being extruded and fitted with the mounting rod 9 through the spherical surface at the end, and the clamping rod 17 and the adjacent L-shaped fixed rod 16 being fixedly connected by a tension spring 18, the rear side of the mounting rod 9 being provided with clamping holes distributed at equal intervals, the distance between adjacent clamping holes of the mounting rod 9 being equal to the distance between adjacent mounting racks 5, and the clamping rod 17 being inserted into the adjacent clamping holes.

[0040] After adjusting the distance between adjacent motors 101, it is necessary to adjust the distance between adjacent groups of oiling spray pipes 8 by pushing and pulling the telescopic liquid injection frame 7, and in the adjustment process, the telescopic liquid injection frame 7 drives the clamping rod 17 to move synchronously through the L-shaped fixed rod 16 thereon, the clamping rod 17 slides to the side where the tension spring 18 is stretched when the clamping rod 17 is extruded by the mounting rod 9, and when the clamping rod 17 is aligned with the clamping hole, the tension spring 18 resets to drive the clamping rod 17 to be inserted into the corresponding clamping hole, thereby achieving the effect of adjusting and fixing the position of the oiling spray pipe 8.

[0041] The above description is only an embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation using the content of the present application specification, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the present application.
