Description

Technical Field

[0001] This invention relates to the technical field of drive shaft production, and more particularly to a spraying oil device and method for drive shaft production. Background Technology

[0002] In the production of drive shafts, oil spraying is a crucial step in ensuring rust prevention and reducing wear during subsequent assembly. The suitability of the oil spraying equipment directly impacts the quality, cost, and workshop environment of drive shaft production. Currently, existing oil spraying equipment for drive shaft production has significant shortcomings in oil recycling and nozzle maintenance, making it difficult to meet the actual needs of large-scale production.

[0003] Existing equipment mostly adopts an open spraying chamber design, lacking an effective oil collection structure and oil fume collection mechanism. During the spraying process, the atomized oil mist easily disperses and spreads, causing serious oil pollution in the workshop environment, affecting the health of workers, and resulting in a large amount of oil waste. At the same time, the residual oil dripping after spraying is mostly directly discharged or reused after simple sedimentation, without a dedicated filtration, purification, and impurity separation structure. The recovered oil is mixed with impurities such as metal shavings and dust generated during the production of the drive shaft. When reused for spraying, these impurities easily adhere to the surface of the drive shaft, forming particulate defects, affecting the spraying quality, and resulting in low oil utilization rate, significantly increasing production costs.

[0004] In addition, the nozzle, as the core component of the oil spraying device, is easily clogged by sludge and metal dust mixed in the oil. The existing device lacks an online self-cleaning function for the nozzle, and after clogging, it is necessary to stop the machine for disassembly and cleaning, which not only increases the workload of operation and maintenance, but also causes production interruption, reduces production efficiency, and further restricts the continuity and stability of drive shaft production.

[0031] Example 1 Reference Figures 1-5 This is the first embodiment of the present invention, which provides a spraying method for a spraying oil device for drive shaft production, enabling the recycling of waste oil after use and facilitating the cleaning of the spray nozzle 103.

[0032] Fix the drive shaft to the oil injection mechanism 100, start the oil injection mechanism 100 to cover the oil injection area and spray oil, and prevent the oil mist from spreading outside the processing area.

[0033] During and after the oil spraying process, the waste oil is filtered and recycled by the recycling mechanism 200 to ensure the purity of the recycled oil and facilitate its subsequent use.

[0034] After the oil spraying is completed, the self-cleaning mechanism 300 is activated to clean the oil spraying part of the oil spraying mechanism 100 and the filter part of the recovery mechanism 200, so as to avoid the oil spraying part from being blocked and affecting the oil mist generation effect, and to avoid the filter part from being blocked and affecting the waste oil recovery efficiency.

[0035] Example 2 Reference Figures 1-5 In the second embodiment of the present invention, an oil spraying mechanism 100 is provided to achieve a comprehensive oil spraying of the oil spraying area.

[0036] The oil spraying mechanism 100 includes a machining base 101. Oil spray pipes 102 are provided on both sides of the top of the machining base 101. Oil spray nozzles 103 are connected to the inner side of each oil spray pipe 102. Several oil spray nozzles 103 are provided and evenly distributed. A mounting plate 104 is fixedly connected to the rear side of the top of the machining base 101. A cover assembly 105 is provided on the front side of the mounting plate 104. A first motor 106 is fixedly connected to the bottom of the machining base 101. The output end of the first motor 106 extends through to the top of the machining base 101 and is fixedly connected to a tooling plate 107. The tooling plate 107 can be used to fix the drive shaft. The cover assembly 105 includes a transmission groove 105a. A screw 105b is movably connected to the bottom of the inner wall of the transmission groove 105a. A second motor 105c is fixedly connected to the top of the mounting plate 104. The output end of the second motor 105c passes through the inside of the transmission groove 105a and is fixedly connected to the top of the screw 105b. A threaded sleeve 105d is threadedly connected to the bottom of the surface of the screw 105b. A cover sleeve 105e is movably connected to the top of the machining base 101. The two sides of the top of the inner wall of the cover sleeve 105e are fixedly connected to the top of the oil injection pipe 102. Limiting holes 105f are opened on both sides of the bottom front side of the cover sleeve 105e. A limiting rod 105g is slidably connected inside the limiting hole 105f. The bottom of the limiting rod 105g is fixedly connected to the front side of the top two sides of the machining base 101. The threaded sleeve 105d is fixedly connected to the cover sleeve 105e.

[0037] First, precisely fix the drive shaft to be sprayed onto the tooling plate 107, ensuring that the drive shaft is firmly positioned and its coaxiality meets the requirements. This prevents uneven spraying due to drive shaft vibration during the spraying process. After fixing, start the second motor 105c. The output end of the second motor 105c drives the screw 105b in the transmission groove 105a to rotate synchronously. Since the screw sleeve 105d is threadedly connected to the screw 105b and fixedly connected to the cover sleeve 105e, the rotation of the screw 105b will drive the screw sleeve 105d to rotate along the screw 105a. b moves downward along the axis, thereby driving the cover sleeve 105e to move downward synchronously. During this process, the bottom limiting hole 105f of the cover sleeve 105e slides along the limiting rod 105g. The limiting rod 105g guides and limits the cover sleeve 105e, preventing it from shifting or tilting during its movement, until the bottom of the cover sleeve 105e is in contact with the top of the machining base 101, completely enclosing the tooling plate 107, drive shaft, oil spray pipe 102, and oil spray head 103 in a closed space, preventing oil mist from spreading during spraying. After the diffuser sleeve 105e closes completely, the first motor 106 and the oil injection system are activated. The output of the first motor 106 drives the tooling disc 107 to rotate at a constant speed, and the tooling disc 107 drives the drive shaft to rotate synchronously, ensuring that the outer circumference of the drive shaft can be evenly contacted with the oil mist. At the same time, the oil injection system delivers high-pressure oil into the oil injection pipe 102. After being diverted by the oil injection pipe 102, the oil is atomized and sprayed out through several equally spaced oil injection nozzles 103. The atomized oil evenly covers the surface of the rotating drive shaft, achieving comprehensive and uniform oil mist coverage of the drive shaft. During the uniform spraying process, the speed of the first motor 106 and the spraying pressure of the spray nozzle 103 can be adjusted according to the specifications of the drive shaft and the spraying requirements to ensure that the spraying thickness meets the process requirements. After the spraying is completed, the spraying system is turned off and the spraying is stopped. Then, the second motor 105c is started in reverse to drive the screw 105b to rotate in the opposite direction, which in turn drives the screw sleeve 105d and the cover sleeve 105e to move upward until the cover sleeve 105e returns to its initial position. At this time, the sprayed drive shaft can be taken out for subsequent processing.

[0038] Example 3 Reference Figures 1-5 In the third embodiment of the present invention, a recycling mechanism 200 and a self-cleaning mechanism 300 are provided to realize the filtration and recycling of waste oil and the self-cleaning of the oil spraying area and the filtration area.

[0039] The recycling mechanism 200 includes a recycling trough 201, which is located on both sides of the top of the processing base 101. A filter plate 202 is installed inside the recycling trough 201. A collection box 203 is connected to the bottom of the recycling trough 201. Sliding strips 204 are fixedly connected to the top of both sides of the collection box 203. A sliding seat 205 is movably fitted onto the surface of the sliding strip 204. The top of the sliding seat 205 is fixedly connected to the bottom of the processing base 101. A support ring 206 is movably connected to the bottom of the filter plate 202. The surface of the support ring 206 is fixedly connected to the inner wall of the recycling trough 201. Rubber limiting strips 207 are provided on the front and rear sides of the top of the filter plate 202. The outer sides of the rubber limiting strips 207 are fixedly connected to the inner wall of the recycling trough 201. Pull rings 208 are fixedly connected to the front and rear sides of the top of the filter plate 202. The self-cleaning mechanism 300 includes a support plate 301. Two support plates 301 are provided. The two sides of the support plate 301 are connected to the recycling trough 202. The top of both sides of the inner wall of the collection tank 201 is fixedly connected, and the top of the support plate 301 is fixedly connected to the jet head 302. The bottom of the fuel injection pipe 102 is connected to a one-way air intake valve 303. The bottom of the one-way air intake valve 303 is inserted into the top of the jet head 302. The jet head 302 is connected to an external air source. The jet head 302 injects air into the fuel injection pipe 102 through the one-way air intake valve 303 to achieve jet cleaning of the fuel injection head 103. The bottom of the front and back of the fuel injection pipe 102 is also fixedly connected. All are connected to a jet pipe 304. A jet box 305 is provided on the front and rear sides of the top of the filter plate 202. An air guide plate 306 is fixedly connected to the top of the inner side of the jet box 305. A one-way pressure valve 307 is connected to the top of the jet box 305. The jet box 305 is connected to the other end of the jet pipe 304 through the one-way pressure valve 307. The air pressure generated by the external air source is higher than the oil pressure when the fuel injector 103 injects fuel. The oil pressure when injecting fuel is insufficient to open the one-way pressure valve 307.

[0040] During the spraying process by the spraying mechanism 100, the atomized oil mist that does not adhere to the surface of the drive shaft settles within the enclosed space of the cover sleeve 105e and drips onto the top of the machining base 101. It then flows down the slope of the top of the machining base 101 into the recovery tanks 201 on both sides. Simultaneously, excess oil on the surface of the drive shaft drips down the drive shaft and also flows into the recovery tanks 201. The waste oil in the recovery tanks 201 first passes through the filter plate 202, which filters out impurities such as metal fragments and dust. The filtered pure waste oil passes through the filter plate 202 and flows into the collection box 203 for storage via the channel at the bottom of the recovery tank 201. The support ring 206 at the bottom of the filter plate 202 supports the filter plate 202, preventing it from deforming due to the weight of the waste oil and impurities. The rubber limiting strip 207 laterally limits the filter plate 202, preventing it from shifting under the impact of the waste oil and ensuring stable filtration. When the filter plate 202 has been used for a period of time, a large amount of impurities will be attached to its surface. At this time, the filter plate 202 can be removed from the recycling tank 201 by pulling the pull ring 208 on the top of the filter plate 202 for cleaning or replacement. After cleaning or replacement, the filter plate 202 is put back into the recycling tank 201, fitting the support ring 206 and locking it between the rubber limit strips 207 to complete the reset. When the waste oil in the collection box 203 reaches a certain amount, the collection box 203 can be pulled outward directly. The sliding strips 204 on both sides of the collection box 203 slide along the slide seat 205 to separate the collection box 203 from the processing seat 101, making it easy to take out the recycled waste oil in the collection box 203 for further processing and reuse, reducing production costs. After the waste oil is taken out, the collection box 203 is pushed back to its original position. The sliding strips 204 and the slide seat 205 cooperate to achieve positioning, ensuring that the collection box 203 is accurately connected to the channel at the bottom of the recycling tank 201 to avoid waste oil leakage.The self-cleaning operation is performed after spraying is completed. After the spraying system is shut down, the external air source is activated, supplying high-pressure gas to the nozzle 302. Since the air pressure generated by the external air source is higher than the oil pressure during spraying from the nozzle 103, the high-pressure gas can smoothly open the one-way inlet valve 303 and enter the spray pipe 102. The high-pressure gas flows rapidly within the spray pipe 102, purging the inner wall of the spray pipe 102 and the nozzle 103, removing residual oil and sludge and impurities adhering to the nozzle 103 nozzle, preventing clogging of the nozzle 103, ensuring smooth subsequent spraying, and reducing the workload of nozzle disassembly and cleaning. Part of the high-pressure gas in the spray pipe 102 is delivered to the spray box 305 through the jet pipe 304. When the gas pressure reaches the opening threshold of the one-way pressure valve 307, the one-way pressure valve 307 opens, releasing the high-pressure gas. The gas enters the jet box 305 and is guided by the air guide plate 306 on the top inner side of the jet box 305, and is evenly sprayed onto the surface of the filter plate 202. The high-pressure gas blows away the impurities attached to the surface of the filter plate 202, preventing impurities from clogging the pores of the filter plate 202, ensuring the filtration efficiency of the filter plate 202 and the smoothness of waste oil recovery. The impurities generated during the blowing can flow into the collection box 203 along with a small amount of residual waste oil, and are subsequently treated together with the waste oil. It should be noted that during the oil spraying process, the oil pressure of the spray head 103 is insufficient to open the one-way pressure valve 307, so the oil will not enter the jet box 305 through the jet pipe 304, avoiding affecting the oil spraying effect and the purity of the recovered waste oil. After self-cleaning is completed, the external air source is turned off, and the one-way air inlet valve 303 and the one-way pressure valve 307 automatically close to prevent oil leakage during subsequent oil spraying.

[0041] The remaining structure is the same as that in Example 2.

[0042] Example 4 Reference Figures 1-5 This is the fourth embodiment of the present invention, which differs from the third embodiment in that: this embodiment provides a spraying oil device and method for drive shaft production.

[0043] The drive shaft to be sprayed is fixed on the tooling plate 107, ensuring a firm fixation and proper coaxiality. Next, the second motor 105c is started, driving the screw 105b to rotate. The screw sleeve 105d moves downwards along the screw 105b, causing the cover sleeve 105e to move downwards synchronously. The limiting hole 105f slides along the limiting rod 105g until the bottom of the cover sleeve 105e is in contact with the top of the machining base 101, completely enclosing the drive shaft, oil spray pipe 102, and oil spray head 103 within the cover sleeve 105e to prevent oil mist diffusion. Afterwards, the first motor 106 and the oil spraying system are started. The first motor 106 drives the tooling plate 107 and the drive shaft to rotate at a constant speed. The oil injection system delivers high-pressure oil to the oil injection pipe 102. After the oil is atomized by the oil nozzle 103, it is evenly sprayed onto the surface of the rotating drive shaft. The motor speed and oil injection pressure are adjusted according to the drive shaft specifications to ensure uniform spraying and the required thickness. During the spraying process, the unattached oil mist settles and drips down, while excess oil drips down the drive shaft and flows into the recovery tanks 201 on both sides. At the same time, the waste oil in the recovery tanks 201 flows through the filter plate 202, which filters out impurities such as metal shavings and dust. The filtered pure waste oil... The waste oil flows into the collection box 203 for storage, realizing the recycling of waste oil. Waste oil recycling continues during the spraying process to ensure no waste oil is wasted or leaked. After spraying, the spraying system and the first motor 106 are turned off, while the second motor 105c remains stationary (or the cover sleeve 105e is reset to a semi-open state as needed). An external air source is activated, and high-pressure gas enters the spray pipe 102 through the jet nozzle 302 and the one-way intake valve 303, purging the inner wall of the spray pipe 102 and the spray nozzle 103 to remove residual oil and impurities. Simultaneously, some high-pressure gas enters through the jet pipe 304 and the one-way pressure valve 307. After being guided by the air guide plate 306, the air jet box 305 blows the surface of the filter plate 202 to remove the attached impurities and prevent clogging. After self-cleaning, the external air source and the second motor 105c are turned off, the cover sleeve 105e is reset to the initial position, and the sprayed drive shaft is taken out. When the waste oil in the collection box 203 reaches a certain amount, the collection box 203 is pulled to take out the recycled waste oil for further processing and reuse. The filter plate 202 is checked regularly. If there are too many impurities on the surface, the pull ring 208 is pulled to take out the filter plate 202, clean or replace it, and then reset it to ensure long-term stable operation of the device.

[0044] In summary, the drive shaft is fixed to the oil injection mechanism 100. The oil injection mechanism 100 is activated to cover the oil injection area and spray oil, preventing oil mist from spreading outside the processing area. During and after the oil injection process, the waste oil is filtered and recycled by the recycling mechanism 200 to ensure the purity of the recycled oil and facilitate its subsequent use. After the oil injection is completed, the self-cleaning mechanism 300 is activated to clean the oil injection area of ​​the oil injection mechanism 100 and the filter of the recycling mechanism 200 to prevent clogging of the oil injection area from affecting the oil mist generation effect and to prevent clogging of the filter from affecting the waste oil recycling efficiency.
