DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0034] like Figures 1 to 7 As shown, the utility model is an intelligent automatic polishing equipment for metal parts, comprising: a body 1, a clamping mechanism for clamping and fixing a metal tube, and a polishing mechanism for polishing the metal tube after clamping and fixing; the polishing mechanism comprises: a polishing assembly for polishing the metal tube, and a water spray assembly for dust removal and cooling during the polishing process; the polishing assembly comprises: a moving platform 7 arranged in the inner cavity of the body 1, a driving unit 2 6 for driving the moving platform 7 to move horizontally, a base 9 arranged on the top of the moving platform 7, a moving module 8 installed on the top of the moving platform 7 and driving the base 9 to move longitudinally, an installation box 10 fixedly installed on the top of the base 9, a double-axis motor fixedly installed in the inner cavity of the installation box 10, and a polishing disc 11 fixedly installed at one end of the output shaft of the double-axis motor; the driving unit 2 6 comprises: a motor 2 fixedly installed on the inner wall of the body 1, and a threaded rod 2 fixedly installed at one end of the output shaft of the motor 2 and driving the moving platform 7 to move horizontally.

[0035] When the metal pipe is polished, by starting the moving module 8, the installation box 10 can be driven to move longitudinally, and then the polishing disc 11 can be driven to move longitudinally, so that the polishing disc 11 can be easily contacted with the outside of the metal pipe. At this time, the polishing disc 11 can be driven to rotate by starting the dual-axis motor, and the outer edge of the metal pipe can be polished by the polishing disc 11. At this time, by starting the second motor, the threaded rod second can be driven to rotate, and the moving platform 7 can be driven to move horizontally by the second threaded rod, and then the polishing disc 11 can be driven to move horizontally, so that any position on one side of the outer edge of the metal pipe can be polished, thereby improving the convenience of polishing.

[0036] It is supplemented here that the moving module 8 is composed of a moving cylinder and a limit rail. The moving cylinder can drive the base 9 to move in a straight line, and the limit rail can guide and limit the base 9 when it moves, thereby improving the stability of the base 9 when it moves.

[0037] The water spray assembly includes: a water tank 12 installed at the bottom of the inner cavity of the body 1, a filter screen 13 attached to the top of the water tank 12, a fixing plate fixedly installed on the outside of the installation box 10, a transverse pipe 18 fixedly installed on the top of the fixing plate, a water inlet pipe 14 plugged into the bottom of the transverse pipe 18, a retractable hose plugged between the bottom end of the water inlet pipe 14 and the side wall of the water tank 12, a water outlet pipe 15 plugged into the top of the transverse pipe 18, a nozzle fixedly installed at one end of the water outlet pipe 15, and a control unit for controlling the water inflow and outflow.

[0038] While the metal pipe is being polished, the control unit delivers the water flow in the inner cavity of the water tank 12 to the transverse pipe 18 through the water inlet pipe 14, and then enters the inner cavity of the water outlet pipe 15 through the transverse pipe 18, and then is sprayed out through the nozzle, which points to the polishing disc 11, thereby achieving polishing and spraying water at the same time. The debris and dust generated during polishing can be washed away by spraying water, so that the debris and dust generated during polishing can be cleaned up in time, avoiding the problem that a lot of debris and dust will be generated during polishing, and the debris and dust will be scattered everywhere if not handled in time, affecting the working environment. The sewage after washing flows downward to the water tank 12. The debris in the sewage can be filtered through the filter net 13 on the top of the water tank 12, and the debris is retained on the top of the filter net 13. The filtered water flows into the water tank 12, thereby realizing the recycling of water and playing a role in saving water resources. At the same time, since the water flow is sprayed on the polishing part of the metal pipe, the polishing part of the metal pipe can be cooled, the polishing effect is improved, and a large amount of heat is avoided in the polishing process of the metal pipe due to the effect of friction. If the heat cannot be dissipated in time, the metal pipe may be thermally deformed, resulting in the problem of dimensional accuracy and shape stability being affected.

[0039] From the above, it can be seen that the equipment realizes polishing and spraying water at the same time, which can not only wash away the debris and dust generated during polishing, thereby timely cleaning the debris and dust generated during polishing, but also cool down the polishing part of the metal pipe, thereby improving the polishing effect.

[0040] The control unit includes: a cylinder 16 fixedly mounted on the other end of the output shaft of the dual-axis motor, a ring 17 sleeved on the outer edge of the cylinder 16, a limit tube 19 plugged and mounted on the side wall of the ring 17, a limit rod 20 installed through the inner cavity of the limit tube 19, a piston 25 fixedly mounted at one end of the limit tube 19, and an opening and closing member 1 for controlling the opening and closing of the inner cavity of the water inlet pipe 14. The opening and closing member 1 includes: a horizontal bar 1 fixedly mounted on the inner cavity of the water inlet pipe 14, a movable rod 2 30 installed through one side wall of the horizontal bar, a movable block 2 31 fixedly mounted on one end of the movable rod 2 30, an arc plug 2 32 fixedly mounted on the other end of the movable rod 2 30, A return spring 233 is fixedly installed between an arc plug 232 and a cross bar 1; and an opening and closing member 2 for controlling the opening and closing of the inner cavity of the water outlet pipe 15, the opening and closing member 2 comprises: a cross bar 2 fixedly installed in the inner cavity of the water outlet pipe 15, a movable rod 26 installed through the side wall of the cross bar 2, a movable block 27 fixedly installed at one end of the movable rod 26, an arc plug 28 fixedly installed at the other end of the movable block 27, and a return spring 29 fixedly installed between the arc plug 28 and the cross bar 2; a guide groove is provided on the outer edge of the cylinder 16, a bull's eye ball is fixedly installed on the inner wall of the ring 17, and the bull's eye ball is slidably installed in the inner cavity of the guide groove.

[0041] While the dual-axis motor drives the polishing disc 11 to grind the metal tube, it can drive the cylinder 16 to rotate. Due to the guiding effect of the guide groove on the outer edge of the cylinder 16 on the bull's eye ball, the cylinder 16 can drive the bull's eye ball to move when it rotates, and then the ring 17 moves. The ring 17 can be limited by the cooperation between the limit rod 20 and the limit tube 19, and then the rotation of the cylinder 16 can drive the ring 17 to reciprocate in the horizontal direction, and the limit tube 19 can be driven to move by the ring 17, and the piston 25 can be driven to reciprocate in the inner cavity of the horizontal tube 18 by the limit tube 19.

[0042] It should be added here that the guide groove is two U-shaped grooves in opposite directions and interpenetrating with each other.

[0043] When the piston 25 moves to the left, negative pressure is generated in the inner cavity of the transverse tube 18. At this time, the arc plug 232 moves upward due to the negative pressure, and the arc plug 1 28 does not move, so that the arc plug 232 has no sealing effect on the inner cavity of the water inlet pipe 14, and drives the return spring 233 to be compressed. At this time, the water in the inner cavity of the water tank 12 can be sucked into the inner cavity of the transverse tube 18. As the water flows into the inner cavity of the transverse tube 18, the pressure inside and outside the transverse tube 18 is balanced. The elastic force of the return spring 233 can drive the arc plug 232 to reset, so that the arc plug 232 seals the water inlet pipe 14.

[0044] When the piston 25 moves to the right, it can squeeze the water in the inner cavity of the transverse tube 18. The water pressure pushes the arc plug 28 open, and the arc plug 2 32 does not move. The arc plug 28 can drive the return spring 29 to be compressed. At this time, the arc plug 28 has no sealing effect on the water outlet pipe 15, and the water flows into the inner cavity of the water outlet pipe 15 and is sprayed out through the nozzle. When the water in the inner cavity of the transverse tube 18 flows out completely, the pressure inside and outside the transverse tube 18 is balanced. At this time, the elastic force of the return spring 29 can drive the arc plug 28 to reset, so that the arc plug 28 seals the water outlet pipe 15.

[0045] As can be seen from the above, the left and right reciprocating movement of the piston 25 can drive the arc plug 1 28 and the arc plug 2 32 to move, so that the water flow is sucked out from the inner cavity of the water tank 12 and sprayed out through the nozzle, realizing water spraying while polishing, without the need for manual control of the water spraying, thereby improving the degree of automation of the equipment, and further enabling the equipment to realize polishing and spraying water at the same time, which can not only wash away the debris and dust generated during polishing, thereby timely cleaning the debris and dust generated during polishing, but also cool the polishing part of the metal pipe, thereby improving the polishing effect.

[0046] A fixed rod 21 is fixedly installed at the bottom of the movable platform 7, a sleeve 22 is sleeved on the outer edge of the fixed rod 21, a scraper 24 is fixedly installed at the bottom end of the sleeve 22, the bottom of the scraper 24 and the top of the filter screen 13 are arranged to fit each other, and a linkage spring 23 is fixedly installed between the bottom end of the fixed rod 21 and the inner wall of the sleeve 22.

[0047] When the movable platform 7 moves horizontally, the fixed rod 21 can be driven to move, and the sleeve 22 can be driven to move by the fixed rod 21, and the scraper 24 can be driven to move horizontally by the sleeve 22. The movement of the scraper 24 can scrape the debris on the top of the filter screen 13 to both sides, so that the debris accumulates on both sides of the top of the filter screen 13, thereby preventing the debris from clogging the filter screen 13 and affecting the filtering effect.

[0048] Due to the elastic force of the linkage spring 23, the bottom of the scraper 24 is always in contact with the top of the filter 13, thereby improving the effect of scraping debris. Since two limit plates are installed at the bottom of the filter 13, when the filter 13 is installed on the top of the water tank 12, the two limit plates are stuck in the inner cavity of the water tank 12, so that the filter 13 can be fixed, avoiding the displacement of the filter 13 during scraping. When it is necessary to deal with the debris on the top of the filter 13, the scraper 24 is pulled upward to separate the scraper 24 from the filter 13. At this time, the filter 13 can be taken out from the top of the water tank 12, so that the filter 13 can be cleaned and reset after cleaning.

[0049] The clamping mechanism includes: a three-jaw chuck 1 3 installed inside the body 1, a rotating motor that drives the three-jaw chuck 1 3 to rotate, a three-jaw chuck 2 4 arranged in the inner cavity of the body 1, and a driving unit 1 5 that drives the three-jaw chuck 2 4 to move horizontally. The driving unit 1 5 includes: a motor 1 fixedly installed on the inner wall of the body 1, and a threaded rod 1 fixedly installed at one end of the output shaft of the motor 1 and driving the three-jaw chuck 2 4 to move horizontally.

[0050] By inserting one end of the metal tube into the three-jaw chuck 1 3, one end of the metal tube can be automatically clamped and fixed by the three-jaw chuck 1 3. At this time, by starting the motor 1, the threaded rod 1 is driven to rotate, and the three-jaw chuck 2 4 is driven to move by the threaded rod 1, so that the three-jaw chuck 2 4 is close to the other end of the metal tube. When the other end of the metal tube is inserted into the three-jaw chuck 2 4, the other end of the metal tube can be automatically clamped and fixed by the three-jaw chuck 2 4, so that the equipment can automatically clamp and fix the metal tube, without manual clamping, thereby improving work efficiency, and the clamping stability is high, avoiding the shaking of the metal tube during polishing, which affects the polishing accuracy. In addition, since the three-jaw chuck 2 4 can be moved, the three-jaw chuck 1 3 and the three-jaw chuck 2 4 cooperate with each other, so that metal tubes of different lengths and diameters can be clamped and fixed, thereby improving the applicability of the equipment.

[0051] When one side of the metal tube is polished, two rotating motors are started at the same time to respectively drive the three-jaw chuck 1 3 and the three-jaw chuck 2 4 to rotate, and the three-jaw chuck 1 3 and the three-jaw chuck 2 4 jointly drive the metal tube to rotate, so that the metal tube can be turned over, so that different sides of the metal tube can be polished, thereby improving the use effect of the equipment.

[0052] A sliding door 2 is slidably mounted on the machine body 1 via a guide rail, and a visual window is mounted on the sliding door 2 .

[0053] When polishing the metal pipe, the sliding door 2 can be closed to prevent the debris generated during polishing from splashing to the outside of the machine body 1, thereby ensuring the personal safety of the staff and preventing the debris from polluting the working environment. The setting of the viewing window allows the staff to observe the polishing situation.

[0054] A PLC controller is installed on the outside of the machine body 1, and the PLC controller is electrically connected to the motor 1, the motor 2, the dual-axis motor, the three-jaw chuck 1 3, and the rotating motor.

[0055] When the metal pipe is clamped and fixed, one end of the metal pipe is inserted into the three-jaw chuck 1 3, and the PLC controller controls the starting of the three-jaw chuck 1 3, and one end of the metal pipe can be automatically clamped and fixed by the three-jaw chuck 1 3, and then the PLC controller controls the starting of the motor 1, thereby driving the threaded rod 1 to rotate, and the three-jaw chuck 2 4 is driven to move by the threaded rod 1, so that the three-jaw chuck 2 4 is close to the other end of the metal pipe. When the other end of the metal pipe is inserted into the three-jaw chuck 2 4, the PLC controller controls the starting of the three-jaw chuck 2 4, and the other end of the metal pipe can be automatically clamped and fixed by the three-jaw chuck 2 4, so that the equipment can automatically clamp and fix the water inlet pipe, without manual clamping, thereby improving work efficiency, and the clamping stability is high, avoiding the shaking of the metal pipe during polishing, which affects the polishing accuracy. In addition, metal pipes of different lengths and diameters can be clamped and fixed, thereby improving the applicability of the equipment.

[0056] When the metal pipe is polished after the fixation is completed, the PLC controller is used to control the start of the moving cylinder, which can drive the installation box 10 to move longitudinally, and then drive the polishing disc 11 to move longitudinally, so that the polishing disc 11 is easy to contact with the outside of the metal pipe. At this time, the PLC controller is used to control the start of the dual-axis motor to drive the polishing disc 11 and the cylinder 16 to rotate, thereby realizing polishing and spraying water at the same time, which can not only wash away the debris and dust generated during polishing, so that the debris and dust generated during polishing can be cleaned in time, but also the polishing part of the metal pipe can be cooled, thereby improving the polishing effect. At this time, the PLC controller is used to control the start of motor 2, which can drive the threaded rod 2 to rotate, and the threaded rod 2 drives the moving platform 7 to move horizontally, and then the polishing disc 11 can be driven to move horizontally, so that any position on one side of the outer edge of the metal pipe can be polished, thereby improving the convenience of polishing.

[0057] When one side of the metal tube is polished, the PLC controller simultaneously controls the start of two rotating motors to respectively drive the three-jaw chuck 1 3 and the three-jaw chuck 2 4 to rotate, and the three-jaw chuck 1 3 and the three-jaw chuck 2 4 jointly drive the metal tube to rotate, so that the metal tube can be turned over, so that different sides of the metal tube can be polished, thereby improving the use effect of the equipment.

[0058] Working principle: when in use, first insert one end of the metal tube into the three-jaw chuck 1 3, and one end of the metal tube can be automatically clamped and fixed by the three-jaw chuck 1 3. At this time, move the three-jaw chuck 2 4 close to the other end of the metal tube. When the other end of the metal tube is inserted into the three-jaw chuck 2 4, the other end of the metal tube can be automatically clamped and fixed by the three-jaw chuck 2 4, so that the equipment can automatically clamp and fix the water inlet pipe. After the fixation is completed, start the moving cylinder to drive the installation box 10 to move longitudinally, and then drive the polishing disc 11 to move longitudinally, so that the polishing disc 11 is easy to contact with the outside of the metal tube. At this time, start the double-axis motor to drive the polishing disc 11 and the cylinder 16 to rotate, so as to achieve polishing and spraying water at the same time, which can not only remove the debris generated during polishing The dust can be washed away, so that the debris and dust generated during polishing can be cleaned in time, and the polishing part of the metal pipe can be cooled down, thereby improving the polishing effect. At this time, by starting the motor 2, the threaded rod 2 can be driven to rotate, and the movable table 7 can be driven to move horizontally by the threaded rod 2, and then the polishing disc 11 can be driven to move horizontally, so that any position on one side of the outer edge of the metal pipe can be polished, thereby improving the convenience of polishing. After the polishing of one side of the metal pipe is completed, the two rotating motors are started at the same time, and the three-jaw chuck 1 3 and the three-jaw chuck 2 4 are driven to rotate respectively, and the metal pipe is driven to rotate by the three-jaw chuck 1 3 and the three-jaw chuck 2 4 together, so that the metal pipe can be turned over, so that different sides of the metal pipe can be polished, thereby improving the use effect of the equipment.
