Description

Technical Field

[0001] The invention relates to the technical field of screw oiling processing, in particular to a screw oiling device and method with an adaptive clamping function. Background Art

[0002] The screw oiling process is to spray lubricating oil evenly on the surface of the screw to reduce the wear of the screw during rotation. The lubricating oil on the outer wall of the screw quickly transfers and cools the heat generated by the friction of the screw, thereby improving the wear resistance and lubricity of the screw and extending the service life of the screw.

[0003] Most of the existing screw oiling devices use electrostatic oiling. By grounding the screw and energizing the coated nozzle, the oil and gas sprayed from the nozzle are charged, so that the oil and gas quickly adhere to the surface of the screw, thereby improving the efficiency of oil spraying. At the same time, due to the charge on the oil and gas, when spraying on the surface of the screw, the oil and gas will be more easily attracted by the protruding parts, so that more oil adheres to the protruding parts of the screw surface, resulting in uneven screw oiling and affecting the wear resistance of the screw. Summary of the invention

[0004] The object of the present invention is to provide a screw oiling device and method with an adaptive clamping function to solve the problems raised in the above-mentioned background technology.

[0006] The support truss includes a positioning base plate and a linear guide rail, the positioning base plate is horizontally arranged, a linear guide rail is arranged on one side of the positioning base plate, a linear drive module is arranged on the inner wall of the linear guide rail, and the linear guide rail is connected to the rotating mechanism through the linear drive module. By moving the horizontal position of the rotating mechanism through the linear drive module in the linear guide rail, it is convenient for the staff to quickly adjust the position of the rotating mechanism to a position matching the length of the screw body, saving the time consumed by the staff in carrying and moving the screw body, and improving the working efficiency of the device.

[0007] The rotating mechanism includes a fixed frame and a movable frame, the bottom of the fixed frame is connected to the upper surface of the positioning base plate, the bottom of the movable frame is connected to the linear guide rail, the top of the fixed frame is provided with a driving motor, the top of the movable frame is provided with a hydraulic telescopic rod, and the clamping assembly is provided with two, and the clamping assembly is respectively connected to the output shaft of the driving motor and the output rod of the hydraulic telescopic rod. The horizontal position of the clamping assembly is adjusted by the hydraulic telescopic rod, so that the clamping assembly can quickly clamp the screw body, and then the screw body is driven to rotate by the driving motor, and the screw body is oiled by the spraying mechanism, which reduces the manual operation of the device and improves the automation of the device.

[0008] The clamping assembly includes a rotating plate, one side of the rotating plate is connected to the hydraulic telescopic rod, a sliding groove is opened on the rotating plate, a blocking block is arranged on the inner wall of the sliding groove, a baffle is arranged on the side of the blocking block away from the hydraulic telescopic rod, a movable roller is arranged on one side of the baffle, a rotating rod is arranged on the side of the baffle close to the movable roller, an end of the rotating rod away from the baffle is hinged with a connecting clamping plate, a side of the connecting clamping plate close to the movable roller is provided with a resisting long rod, a spring is arranged on the other side of the connecting clamping plate, one end of the resisting long rod is connected to the screw body, and the end of the spring away from the connecting clamping plate is connected to the rotating plate. One end of the screw body is pushed toward the direction of the rotating plate to resist the movement of the long rod, and the long rod drives the connecting clamp plate to move, so that the connecting clamp plate drives the rotating rod to deflect, and at the same time the connecting clamp plate squeezes the spring, and the rotating rod deflects and pulls the baffle plate at the other end to move, so that the baffle plate slides along the slide groove through the clamp block, and the movable roller on one side of the baffle plate clamps one end of the screw body, so that the device can clamp screw bodies of various cross-sectional areas, thereby improving the applicability of the device.

[0009] The baffles are provided with three, and the baffles are equidistantly distributed in a ring around the center point of the rotating plate. Two movable rollers are hinged on one side of the baffle, and the movable rollers are symmetrically distributed about the horizontal midline of the baffle. The outer wall of the movable roller is connected to one end of the screw body. The movable roller is distributed in a ring along with the baffles, and the movable roller can rotate along one side of the baffle. The driving motor drives the screw body to rotate through the clamping assembly. After the screw body stops rotating, the screw body can drive the movable roller to rotate, so as to buffer the rotational inertia of the screw body, thereby avoiding the problem of wear of the clamping positions at both ends of the screw body caused by the rotational inertia of the screw body.

[0010] The spraying mechanism includes a movable side plate, the bottom of the movable side plate is connected to the linear guide rail, a lifting card is arranged on one side of the movable side plate, two lifting cards are arranged, and the lifting cards are vertically distributed up and down with respect to one side of the movable side plate, a material storage box is arranged on the upper surface of the lifting card plate, a nozzle is arranged at the bottom of the lifting card plate, and the nozzle is connected to the material storage box, an electric telescopic rod is arranged on the side of the movable side plate away from the lifting card plate, one end of the electric telescopic rod is connected to the lifting card plate, the nozzle is connected to the power supply, and the movable roller is grounded. The horizontal position of the movable side plate is adjusted by the linear guide rail, and then the electric telescopic rod is started to adjust the vertical height of the lifting card plate, and then the oil in the material storage box is sprayed out through the nozzle, and the nozzle is connected to the power supply so that the oil and gas sprayed out by the nozzle are charged, and an electric field is generated between the oil and gas and the screw body to generate electrostatic adsorption, so that the oil and gas quickly adhere to the screw body, and the current and voltage on the screw body are derived through grounding.

[0011] A recovery component is provided on the side of the lifting pallet away from the storage box, and the recovery component includes a positioning pallet, one side of the positioning pallet is connected to the lifting pallet, one side of the positioning pallet is provided with a rotating shaft, one end of the rotating shaft is provided with a rubber roller, and a fixed sleeve is provided on the side of the positioning pallet close to the rubber roller, two fixed sleeves are provided, and the fixed sleeves are symmetrically distributed at both ends of the rubber roller, the outer wall of the rubber roller is an arc-shaped groove, the rubber roller is inclined with respect to the screw body, and the outer wall of the rubber roller is connected to the screw body through the arc-shaped groove. While the screw body is being oiled, the spray mechanism drives the recovery assembly to move along the screw body, so that the movable side plate moves along the linear guide rail, and the outer wall of the rubber roller rubs against the outer wall of the screw body. The oil and gas sprayed by the nozzle after being electrified are positively charged. The setting of the thread groove in the screw body makes the protruding part of the outer wall of the screw body attract more oil and gas with positive charge, reducing the contact between the oil and gas and the inner wall of the thread groove in the screw body, so that more oil is adhered to the protruding part of the outer wall of the screw body, and the oil and gas are absorbed by the protruding part of the outer wall of the screw body. Under the action of centrifugal force and gravity caused by the rotation of the screw body, the problem of oil dripping is likely to occur. The rubber roller fits with the protruding part of the outer wall of the screw body. When the outer wall of the rubber roller rubs against the screw body, the rubber roller is negatively charged and the screw body is positively charged, so that the oil and gas with positive charge stay away from the protruding part of the screw body, increasing the adhesion of the oil and gas to the thread groove of the screw body. At the same time, the rubber roller adsorbs the positively charged oil and gas on the screw body that has not been electrically neutralized, ensuring the uniform distribution of the oil on the screw body.

[0012] The inner wall of the fixed sleeve is provided with a spiral scraper, and there are three spiral scrapers. The spiral scrapers are equidistantly distributed in a ring about the inner wall of the fixed sleeve. One side of the spiral scraper is fixedly connected to the inner wall of the fixed sleeve, and the other side of the spiral scraper is connected to the outer wall of the rubber roller. The inner wall of the fixed sleeve is provided with a collection chamber, and one side of the collection chamber is connected to the storage box through a conduit. The rubber roller rotates while the screw body rotates, so that the oil body adhered to the outer wall of the rubber roller rotates synchronously. Due to the setting of the arc-shaped groove on the outer wall of the rubber roller, the oil body on the outer wall of the rubber roller is subjected to the action of centrifugal force, and the oil body moves to the two ends of the rubber roller. Then, the spiral scraper is used to scrape the oil body at both ends of the rubber roller. The oil body flows into the collection chamber along the guidance of the spiral scraper, and then the oil body is recovered to the storage box through the guidance of the conduit at the bottom of the collection chamber, thereby improving the environmental protection of the device.

[0013] A method for a screw oiling device with an adaptive clamping function, the method comprising the following specific steps: S1. Clamp and fix the screw body through the clamping assembly; S2, rotating the screw body through a rotating mechanism; S3, starting the spraying mechanism to apply oil to the outer wall of the screw body; S4. After oiling is completed, loosen the clamping assembly and take out the screw body.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. Through the arrangement of the supporting truss, the rotating mechanism and the clamping assembly, the device can quickly clamp the screw body, thereby improving the working efficiency of the device. One end of the screw body is pushed toward the direction of the rotating plate to move the resisting long rod, and the resisting long rod drives the connecting clamping plate to move, so that the connecting clamping plate drives the rotating rod to deflect. When the rotating rod deflects, the baffle plate at the other end is pulled to move, so that the baffle plate slides along the slide groove through the clamping block, and the movable roller on one side of the baffle plate clamps one end of the screw body, so that the device can clamp screw bodies of various cross-sectional sizes, thereby improving the applicability of the device.

[0015] 2. Through the arrangement of the supporting truss, the rotating mechanism, the clamping assembly and the spraying mechanism, the device can efficiently carry out oil coating processing on the outer wall of the screw body. The movable side plate in the spraying mechanism slides along the linear guide rail, and the oil and gas with electric charge are sprayed on the screw body through the nozzle, which reduces the labor consumption of the device and improves the degree of automation of the device.

[0016] 3. Through the arrangement of the supporting truss, the rotating mechanism, the clamping assembly, the spraying mechanism and the recycling assembly, the device can evenly apply oil to the outer wall of the screw body. Through the friction between the rubber roller and the outer wall of the screw body, the problem of a large amount of charged oil and gas adhering to the protruding part of the outer wall of the screw body is avoided. At the same time, the excess oil can be recycled, which reduces the waste of oil by the device and improves the environmental protection of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Three baffles 304 are provided, and the baffles 304 are equidistantly distributed in a ring about the center point of the rotating plate 301. Two movable rollers 305 are hinged on one side of the baffle 304, and the movable rollers 305 are symmetrically distributed about the horizontal midline of the baffle 304.

The driving motor 202 drives the screw body 4 to rotate through the clamping assembly 3. After the screw body 4 stops rotating, the screw body 4 can drive the movable roller 305 to rotate, so as to buffer the rotation inertia of the screw body 4, thereby avoiding the problem of wear of the clamping positions at both ends of the screw body 4 caused by the rotation inertia of the screw body 4.

[0025] The spraying mechanism 5 includes a movable side panel 501, the bottom of which is connected to the linear guide rail 102, a lifting card plate 502 is arranged on one side of the movable side panel 501, two lifting card plates 502 are arranged, and the lifting card plates 502 are vertically distributed up and down with respect to one side of the movable side panel 501, a material storage box 503 is arranged on the upper surface of the lifting card plate 502, a nozzle 504 is arranged at the bottom of the lifting card plate 502, and the nozzle 504 is connected to the material storage box 503, an electric telescopic rod 505 is arranged on the side of the movable side panel 501 away from the lifting card plate 502, one end of the electric telescopic rod 505 is connected to the lifting card plate 502, the nozzle 504 is electrically connected, and the movable roller 305 is grounded. The horizontal position of the movable side plate 501 is adjusted by the linear guide rail, and then the electric telescopic rod 505 is started to adjust the vertical height of the lifting card plate 502, and then the oil in the storage box 503 is sprayed out through the nozzle 504. The nozzle 504 is connected to the power supply so that the oil and gas sprayed by the nozzle 504 are charged, and an electric field is generated between the oil and gas and the screw body 4 to cause electrostatic adsorption, so that the oil and gas quickly adhere to the screw body 4, and the current and voltage on the screw body 4 are derived through grounding.

[0026] A recovery component 6 is provided on the side of the lifting card plate 502 away from the storage box 503, and the recovery component 6 includes a positioning card plate 601, one side of the positioning card plate 601 is connected to the lifting card plate 502, one side of the positioning card plate 601 is provided with a rotating shaft 602, one end of the rotating shaft 602 is provided with a rubber roller 603, and a fixed sleeve 604 is provided on the side of the positioning card plate 601 close to the rubber roller 603. There are two fixed sleeves 604, which are symmetrically distributed at both ends of the rubber roller 603. The outer wall of the rubber roller 603 is an arc-shaped groove shape, and the rubber roller 603 is inclined with respect to the screw body 4. The outer wall of the rubber roller 603 is connected to the screw body 4 through the arc-shaped groove. While the screw body 4 is being oiled, the spray mechanism 5 drives the recovery assembly 6 to move along the screw body 4, so that the movable side plate 501 moves along the linear guide rail 102, and the outer wall of the rubber roller 603 rubs against the outer wall of the screw body 4. The oil and gas sprayed by the nozzle 504 after being electrically connected are positively charged. The setting of the thread groove in the screw body 4 makes the protruding part of the outer wall of the screw body 4 attract more oil and gas with positive charge, reducing the contact between the oil and gas and the inner wall of the thread groove in the screw body 4, so that more oil is adhered to the protruding part of the outer wall of the screw body 4, and the oil and gas are positively charged. Under the action of centrifugal force and gravity caused by the rotation of the body 4, the problem of oil dripping is likely to occur. The rubber roller 603 fits against the protruding part of the outer wall of the screw body 4. When the outer wall of the rubber roller 603 rubs against the screw body 4, the rubber roller 603 is negatively charged and the screw body 4 is positively charged, so that the oil and gas with the positive charge are kept away from the protruding part of the screw body 4, increasing the adhesion amount of the oil and gas to the thread groove of the screw body 4. At the same time, the rubber roller 603 adsorbs the positively charged oil and gas on the screw body 4 that has not been electrically neutralized, thereby ensuring the uniform distribution of the oil on the screw body 4.

[0027] The inner wall of the fixed sleeve 604 is provided with a spiral scraper 605, and there are three spiral scrapers 605. The spiral scrapers 605 are equidistantly distributed in a ring about the inner wall of the fixed sleeve 604. One side of the spiral scraper 605 is fixedly connected to the inner wall of the fixed sleeve 604, and the other side of the spiral scraper 605 is connected to the outer wall of the rubber roller 603. The inner wall of the fixed sleeve 604 is provided with a collection chamber 606, and one side of the collection chamber 606 is connected to the storage box 503 through a conduit. The rubber roller 603 rotates while the screw body 4 rotates, so that the oil adhered to the outer wall of the rubber roller 603 rotates synchronously. Due to the setting of the arc-shaped groove on the outer wall of the rubber roller 603, the oil on the outer wall of the rubber roller 603 is moved to the two ends of the rubber roller 603 by the action of centrifugal force, and then the oil on the two ends of the rubber roller 603 is scraped off by the spiral scraper 605, and the oil flows into the collection chamber 606 along the guidance of the spiral scraper 605, and then the oil is recovered to the storage box 503 through the guidance of the bottom conduit of the collection chamber 606, thereby improving the environmental protection of the device.

[0028] A method for a screw oiling device with an adaptive clamping function, the method comprising the following specific steps: S1. Clamp and fix the screw body through the clamping assembly; S2, rotating the screw body through a rotating mechanism; S3, starting the spraying mechanism to apply oil to the outer wall of the screw body; S4. After oiling is completed, loosen the clamping assembly and take out the screw body.

[0029] Working principle of the present invention: When the screw body 4 is clamped, the linear drive module in the linear guide 102 moves the horizontal position of the rotating mechanism 2, and the movable frame 203 and the fixed frame 201 are moved to a position matching the length of the screw body 4. Then, one end of the screw body 4 is brought into contact with the long resistance rod 308 in the clamping assembly 3 on one side of the drive motor 202, and one end of the screw body 4 is pushed toward the rotating plate 301 to move the long resistance rod 308, so that the long resistance rod 308 drives the connecting clamp plate 307 to move. , so that the connecting card plate 307 drives the rotating rod 306 to deflect, and at the same time the connecting card plate 307 squeezes the spring 309, and the rotating rod 306 deflects and pulls the baffle plate 304 at the other end to move, so that the baffle plate 304 slides along the slide groove 302 through the block 303, and the movable roller 305 on one side of the baffle plate 304 clamps one end of the screw body 4, and then the hydraulic telescopic rod 204 is started, so that the other end of the screw body 4 is clamped and fixed with the clamping component 3 on one side of the hydraulic telescopic rod 204; The rotating plate 301 is driven to rotate by the driving motor 202, so that the rotating plate 301 drives the screw body 4 to rotate. When the screw body 4 rotates, a triangle structure is formed between the long rod 308, the connecting clamping plate 307, the rotating rod 306, the movable roller 305 and the baffle 304. The positions of the movable roller 305 and the baffle 304 are relatively fixed, and the positions of the connecting clamping plate 307 and the long rod 308 are relatively fixed, so that the shaking of the screw body 4 at one end of the long rod 308 is limited, so that the screw body 4 rotates stably. Then, the outer wall of the screw body 4 is oiled, and the horizontal position of the movable side plate 501 is adjusted by the linear guide rail, and then the electric telescopic rod 505 is started to adjust the vertical height of the lifting card plate 502, so that the outer wall of the rubber roller 603 set on one side of the lifting card plate 502 is in contact with the outer wall of the screw body 4, and then the oil in the storage box 503 is sprayed out through the nozzle 504. The nozzle 504 is connected to the power supply so that the oil and gas sprayed by the nozzle 504 are charged, and an electric field is generated between the oil and gas and the screw body 4 to generate electrostatic adsorption, so that the oil and gas quickly adhere to the screw body 4, and the current and voltage on the screw body 4 are derived through grounding; While the screw body 4 is being oiled, the screw body 4 is rotated by the driving motor 202, the movable side plate 501 is synchronously moved along the linear guide rail 102, the rubber roller 603 is fitted with the protruding part of the outer wall of the screw body 4, and the rubber roller 603 is tilted so that the rubber roller 603 and the screw body 4 are frictionally rotated. When the outer wall of the rubber roller 603 rubs against the screw body 4, part of the electrons on the rubber roller 603 move to the screw body 4, so that the rubber roller 603 is negatively charged and the screw body 4 is positively charged, so that the oil and gas with positive charge are away from the protruding part of the screw body 4, increasing the adhesion amount of the oil and gas to the thread groove of the screw body 4. At the same time, the rubber roller 603 adsorbs the positively charged oil and gas on the screw body 4 that has not been electrically neutralized. When the rubber roller 603 moves laterally along the screw body 4, it blocks the turbine airflow generated by the rotation of the screw body 4, reduces the influence of the airflow on the spraying of the nozzle 504, and makes the oil on the screw body 4 evenly distributed. The rubber roller 603 rotates while the screw body 4 rotates, so that the oil adhered to the outer wall of the rubber roller 603 rotates synchronously. Due to the setting of the arc-shaped groove on the outer wall of the rubber roller 603, the oil on the outer wall of the rubber roller 603 is subjected to the action of centrifugal force, and the oil moves to the two ends of the rubber roller 603. Then, the oil on the two ends of the rubber roller 603 is scraped off by the spiral scraper 605, and the oil flows into the collection chamber 606 along the guidance of the spiral scraper 605. Then, the oil is recovered to the storage box 503 through the guidance of the conduit at the bottom of the collection chamber 606, and the oil is recycled. After the oiling process of the screw body 4 is completed, the driving motor 202 for driving the screw body 4 is stopped, and the outer wall of the screw body 4 is decelerated by the friction of the rubber roller 603. At the same time, the hydraulic telescopic rod 204 is contracted, so that the spring 309 pushes the connecting card plate 307 to move, and the movable roller 305 supports the two ends of the screw body 4 to buffer the rotational inertia of the screw body 4, thereby reducing the wear on the screw body 4 and the wear of the oil layer formed after oiling. The lifting card plate 502 at the top is raised by the electric telescopic rod, and then the screw body 4 is taken out.
