[0022] The present invention also discloses a polishing process of a polishing device for deep hole processing, comprising the following steps:

[0023] S1. Open the machine door and install the workpiece first. Install the workpiece directly in the installation slot of the rotating disk. At this time, the trigger switch is pressed, which can automatically start the drive motor to drive the bidirectional screw to rotate. The two thread blocks installed on the bidirectional screw are close to each other, so that the two bidirectional screws are close to each other, and the bayonet is inserted into the workpiece slot to achieve rapid positioning and clamping of the workpiece;

[0024] S2, at this time, the driving motor is controlled to work, and the rotating disk is driven to rotate rapidly through the installation shaft. At this time, the workpiece also rotates rapidly. At this time, the electric push rod of the lifting and polishing assembly is controlled to work, and the polishing body is controlled to descend through the telescopic rod.

At the same time, the mounting shaft can also drive the external driving gear to rotate. The driving gear can drive the longitudinal shaft with the driven gear to rotate through meshing. The electrostatic adsorption roller outside the longitudinal shaft rotates with the fan blade shaft at the top, so that the fan blades rotate synchronously in the exhaust housing. When the electrostatic adsorption roller rotates, it can quickly eliminate friction with the electrostatic brush, so that a large amount of static electricity is generated on the electrostatic adsorption roller.

[0026] S4.

[0027] S5.

As the polishing body enters the deep hole, the polishing agent is brought into the deep hole of the workpiece to assist polishing.

[0028] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0029] 1. In the present invention, a lifting polishing assembly, a workpiece mounting mechanism and an electrostatic adsorption assembly are arranged inside. When deep hole polishing is performed, the workpiece is mounted in the workpiece mounting mechanism. At this time, the driving motor is controlled to work, and the rotating disk is driven to rotate rapidly through the mounting shaft. At this time, the workpiece also rotates rapidly. At this time, the electric push rod of the lifting polishing assembly is controlled to work, and the polishing body is controlled to descend through the telescopic rod. The polishing body can enter the hole of the rapidly rotating workpiece to perform polishing treatment in the hole. During the polishing process, the position of the polishing body can be adjusted according to the required processing depth. At the same time, the mounting shaft can also drive the external driving gear to rotate. The driving gear can drive the longitudinal shaft with the driven gear to rotate through meshing. The longitudinal shaft The electrostatic adsorption roller outside the shaft rotates with the fan shaft at the top, so that the fan blades rotate synchronously in the exhaust shell. When the electrostatic adsorption roller rotates, it can quickly eliminate friction with the electrostatic brush, so that a large amount of static electricity is generated on the electrostatic adsorption roller. At the same time, the rotating fan blades can generate a certain suction force in the exhaust shell, which can suck up some powder generated in the polishing process, and then be quickly captured by the static electricity on the electrostatic adsorption roller. Through this design, not only can the deep hole polishing processing effect be achieved, it is easy to adjust, and the electrostatic adsorption function of polishing powder in the device can be realized. The dust suction structure is not adopted, which effectively solves the problem that the dust sucked into the vacuum cleaner may fly out due to its small size, and at the same time effectively reduces the overall energy consumption in the equipment.

[0030] 2. In the present invention, a polishing body is provided, and the polishing body is composed of two upper and lower cylinders, and the diameter of the upper cylinder is smaller than the diameter of the lower cylinder. When deep hole polishing is performed, the lower large-diameter cylinder can enter the deep hole. Since the polishing body is in a stepped shape as a whole, the debris generated during the processing will accumulate on the upper surface of the lower cylinder. With the completion of the polishing process, the polishing body is controlled to be lifted, and the polishing body can automatically take out the debris accumulated thereon, and it will not remain in the processed hole. Through this design, the shape of the polishing structure is changed, so that the polishing structure has a good debris discharge function, which can greatly improve the overall deep hole polishing effect, and the debris can be discharged at any time. At the same time, since the polishing body is threadedly screwed onto the threaded end shaft, it is very convenient to replace polishing bodies of different specifications. During polishing, due to the continuous rotation of the workpiece, a certain rotational force can be given to the polishing body, thereby improving the connection effect between the polishing body and the threaded end shaft, and the stability is extremely high.

[0031] 3. In the present invention, a polishing agent storage component is provided inside. When polishing is performed, the telescopic rod of the lifting and lowering polishing component descends, and the side pressure plate can be driven to descend synchronously until the side pressure plate squeezes the storage bag. The polishing agent stored in the storage bag can be effectively guided to the polishing body through the polishing agent nozzle. As the polishing body enters the deep hole, the polishing agent is brought into the deep hole of the workpiece. Through this design, the function of automatic introduction of the polishing agent before polishing is realized, thereby effectively improving the overall polishing effect. At the same time, a clamping component and a trigger switch are provided in the workpiece mounting mechanism. When the workpiece is installed, the workpiece is directly installed in the mounting groove of the rotating disk. At this time, the trigger switch is pressed and the driving motor can be automatically turned on to drive the bidirectional screw to rotate. The two threaded blocks threadedly installed on the bidirectional screw are close to each other, so that the two bidirectional screws are close to each other, and the bayonet is clamped in the workpiece groove, so that the workpiece can be quickly positioned and clamped. Through this design, the workpiece can be quickly positioned and installed, and the application effect is good. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The workpiece mounting mechanism 4 includes a positioning mounting disk 42 and a driving motor 45. The positioning mounting disk 42 is fixedly mounted on the side inner wall of the casing 2, and the driving motor 45 is fixedly mounted on the bottom inner wall of the casing 2. A rotating disk 41 is rotatably mounted inside the positioning mounting disk 42, and a mounting shaft 43 is fixedly mounted on one end of the output shaft of the driving motor 45. A driving gear 44 is fixedly mounted on the outside of the mounting shaft 43, and the top end of the mounting shaft 43 is fixedly connected to the bottom surface of the rotating disk 41.

[0046] The electrostatic adsorption component 5 includes an exhaust shell 51 and a longitudinal shaft 57. The exhaust shell 51 is fixedly mounted on the inner wall of the casing 2 through a connecting rod. An exhaust net 52 is fixedly mounted on the bottom of the exhaust shell 51. An electrostatic brush 53 is rotatably mounted on the bottom of the exhaust net 52 through a rotating shaft. The longitudinal shaft 57 is rotatably mounted on the inner wall of the bottom surface of the casing 2 through a bearing. A driven gear 58 is fixedly mounted on the outside of the longitudinal shaft 57. The driving gear 44 and the driven gear 58 are meshed and connected with each other. The longitudinal shaft 57 passes through an inner hole set inside the positioning mounting plate 42. An electrostatic adsorption roller 56 is fixedly mounted on the outside of the longitudinal shaft 57. The electrostatic adsorption roller 56 is made of rubber. The electrostatic adsorption roller 56 is in close contact and compression with the electrostatic brush 53. A fan blade shaft 54 ​​is fixedly mounted on the top of the longitudinal shaft 57. A fan blade 55 is fixedly mounted on the outside of the fan blade shaft 54. The fan blade 55 is located on the inner side of the exhaust shell 51.

[0047] The specific implementation method is as follows: when performing deep hole polishing, the workpiece is installed in the workpiece installation mechanism 4, and the driving motor 45 is controlled to work, and the rotating disk 41 is driven to rotate rapidly through the installation shaft 43. At this time, the workpiece also rotates rapidly. At this time, the electric push rod 31 of the lifting and polishing assembly 3 is controlled to work, and the polishing body 36 is controlled to descend through the telescopic rod 34. The polishing body 36 can enter the hole of the rapidly rotating workpiece to perform polishing treatment in the hole. During the polishing process, the position of the polishing body 36 can be adjusted according to the required processing depth. At the same time, the installation shaft 43 can also drive the external The driving gear 44 rotates, and the driving gear 44 can drive the longitudinal shaft 57 with the driven gear 58 to rotate through the meshing action. The electrostatic adsorption roller 56 outside the longitudinal shaft 57 rotates with the fan shaft 54 ​​at the top, so that the fan blades 55 rotate synchronously in the exhaust shell 51. When the electrostatic adsorption roller 56 rotates, it can quickly eliminate friction with the electrostatic brush 53, so that a large amount of static electricity is generated on the electrostatic adsorption roller 56. At the same time, the rotating fan blades 55 can generate a certain suction force in the exhaust shell 51, which can suck up some powder generated in the polishing process, and then be quickly captured by the static electricity on the electrostatic adsorption roller 56.

[0048] This design not only achieves deep hole polishing processing effects and is easy to adjust, but also realizes the electrostatic adsorption function of polishing powder in the device. It does not adopt a dust suction structure, which effectively solves the problem that the dust sucked into the vacuum cleaner may fly out due to its small size. At the same time, it effectively reduces the overall energy consumption in the equipment.

[0049] The rotating disk 41 is provided with a mounting groove 46 inside, and a travel groove 49 is provided inside the mounting groove 46. A trigger switch 48 is provided at the center position of the top surface of the mounting groove 46. A fixing component 47 is provided on the mounting groove 46. The fixing component 47 includes a driving motor 471 and a bidirectional screw 473. The driving motor 471 is fixedly installed in the shell cavity of the rotating disk 41, and a bidirectional screw 473 is fixedly installed on one end of the output shaft of the driving motor 471. A threaded block 472 is threadedly installed on the bidirectional screw 473. The bottom end of the threaded block 472 is slidably connected to the inner wall of the bottom surface of the shell cavity of the rotating disk 41, and a fixing arc clamp 474 is fixedly installed on the top of the threaded block 472. The trigger switch 48 is used to control the opening and closing of the driving motor 471, and a bayonet 475 is fixedly installed on the side wall of the fixing arc clamp 474.

[0050] The specific implementation method is as follows: open the machine door 1, install the workpiece first, and directly install the workpiece in the installation slot 46 of the rotating disk 41. At this time, the trigger switch 48 is pressed, and the drive motor 471 can be automatically turned on to drive the bidirectional screw 473 to rotate. The two threaded blocks 472 threadedly installed on the bidirectional screw 473 approach each other, so that the two bidirectional screws 473 approach each other, and the latch 475 is inserted into the workpiece slot, thereby realizing rapid positioning and clamping of the workpiece.

[0051] Through this design, the workpiece can be quickly positioned and installed, and the application effect is good.

[0052] A polishing agent storage assembly 6 is arranged on the top surface of the positioning mounting plate 42, and the polishing agent storage assembly 6 is used for storing and releasing the polishing machine. The polishing agent storage assembly 6 includes a storage bag 62, and an injection tube 61 is fixedly installed on the outer wall of one side of the storage bag 62, one end of the injection tube 61 passes through and extends to the outside of the casing 2, and a polishing agent nozzle 63 is fixedly installed on the outer wall of the other side of the storage bag 62 through a conduit. The lifting polishing assembly 3 includes a top cover 32, and an electric push rod 31 is fixedly installed on the top surface of the top cover 32, and a telescopic rod 34 is arranged on the output end of the electric push rod 31, and a side pressure plate 33 is fixedly installed on the side wall of the telescopic end of the telescopic rod 34 through a connecting rod, and the side pressure plate 33 is located directly above the storage bag 62, and a threaded end shaft 35 is fixedly installed on the bottom end of the telescopic rod 34, and a polishing body 36 is threadedly installed on the threaded end shaft 35, and the polishing body 36 is composed of two upper and lower cylinders, and the diameter of the upper cylinder is smaller than the diameter of the lower cylinder.

[0053] The specific implementation method is as follows: when polishing is performed, the telescopic rod 34 of the lifting and polishing assembly 3 descends, and at the same time, the side pressure plate 33 can be driven to descend synchronously until the side pressure plate 33 squeezes the storage bag 62. The polishing agent stored in the storage bag 62 can be effectively exported to the polishing body 36 through the polishing agent nozzle 63. As the polishing body 36 enters the deep hole, the polishing agent is brought into the deep hole of the workpiece to assist in polishing. When deep hole polishing is performed, the large-diameter cylinder below can enter the deep hole. Since the polishing body 36 is stepped as a whole, the debris generated during the processing will accumulate on the upper surface of the lower cylinder. With the end of the polishing process, the polishing body 36 is controlled to be lifted, and the polishing body 36 can automatically bring out the debris accumulated on it, and it will not remain in the processed hole.

At the same time, by changing the shape of the polishing structure, the polishing structure has a good debris discharge function, which can greatly improve the overall deep hole polishing effect and can discharge the debris at any time. At the same time, since the polishing body 36 is threadedly screwed onto the threaded end shaft 35, it is very convenient to replace polishing bodies 36 of different specifications. During polishing, due to the continuous rotation of the workpiece, a certain rotational force can be given to the polishing body 36, thereby improving the connection effect between the polishing body 36 and the threaded end shaft 35, and the stability is extremely high.

[0055] The present invention also discloses a polishing process of a polishing device for deep hole processing, comprising the following steps:

[0056] S1. Open the machine door 1, first install the workpiece, and directly install the workpiece in the installation slot 46 of the rotating disk 41. At this time, the trigger switch 48 is pressed, and the driving motor 471 can be automatically turned on to drive the bidirectional screw 473 to rotate. The two threaded blocks 472 threadedly installed on the bidirectional screw 473 approach each other, so that the two bidirectional screws 473 approach each other, and the bayonet 475 is clamped in the workpiece slot, so as to realize the rapid positioning and clamping of the workpiece;

[0057] S2, at this time, the driving motor 45 is controlled to work, and the rotating disk 41 is driven to rotate rapidly through the mounting shaft 43. At this time, the workpiece also rotates rapidly. At this time, the electric push rod 31 of the lifting and polishing assembly 3 is controlled to work, and the polishing body 36 is controlled to descend through the telescopic rod 34. The polishing body 36 can enter the hole of the rapidly rotating workpiece to perform polishing treatment in the hole;

[0058] S3. During the polishing process, the position of the polishing body 36 can be adjusted according to the depth of processing required. At the same time, the mounting shaft 43 can also drive the external driving gear 44 to rotate. The driving gear 44 can drive the longitudinal shaft 57 with the driven gear 58 to rotate through meshing. The electrostatic adsorption roller 56 outside the longitudinal shaft 57 rotates with the fan shaft 54 ​​at the top, so that the fan blade 55 rotates synchronously in the exhaust housing 51. When the electrostatic adsorption roller 56 rotates, it can quickly release friction with the electrostatic brush 53, so that a large amount of static electricity is generated on the electrostatic adsorption roller 56. At the same time, the rotating fan blade 55 can generate a certain suction force in the exhaust housing 51, which can absorb some powder generated during the polishing process, and then be quickly captured by the static electricity on the electrostatic adsorption roller 56;

[0059] S4. When deep hole polishing is performed, since the polishing body 36 is in a stepped shape as a whole, the debris generated during the processing will accumulate on the upper surface of the lower cylinder. As the polishing process is completed, the polishing body 36 is controlled to be lifted, and the polishing body 36 can automatically take out the debris accumulated thereon, and will not remain in the processed hole;

[0060] S5. When polishing is performed, when the telescopic rod 34 of the lifting polishing assembly 3 descends, the side pressure plate 33 can be driven to descend synchronously until the side pressure plate 33 squeezes the storage bag 62. The polishing agent stored in the storage bag 62 can be effectively discharged to the polishing body 36 through the polishing agent nozzle 63. As the polishing body 36 enters the deep hole, the polishing agent is brought into the deep hole of the workpiece to assist polishing.

[0061] Working principle: open the machine door 1, first install the workpiece, and directly install the workpiece in the installation groove 46 of the rotating disk 41. At this time, the trigger switch 48 is pressed, which can automatically start the drive motor 471, drive the two-way screw 473 to rotate, and the two threaded blocks 472 threadedly installed on the two-way screw 473 approach each other, so that the two two-way screws 473 approach each other, so that the latch 475 is stuck in the workpiece groove, and the workpiece is quickly positioned and clamped; at this time, the drive motor 45 is controlled to work, and the rotating disk 41 is driven to rotate rapidly through the installation shaft 43. The workpiece rotates rapidly at this time, and the electric push rod 31 controlling the lifting and polishing assembly 3 works at this time, and the polishing body 36 is controlled to descend through the telescopic rod 34, and the polishing body 36 can enter the hole of the rapidly rotating workpiece to perform the polishing process in the hole; during the polishing process, the position of the polishing body 36 can be adjusted according to the required processing depth. At the same time, the mounting shaft 43 can also drive the external driving gear 44 to rotate, and the driving gear 44 can drive the longitudinal shaft 57 with the driven gear 58 to rotate through the meshing action, and the electrostatic adsorption outside the longitudinal shaft 57 The roller 56 rotates with the fan shaft 54 ​​at the top, so that the fan blade 55 rotates synchronously in the exhaust housing 51. When the electrostatic adsorption roller 56 rotates, it can quickly eliminate friction with the electrostatic brush 53, so that a large amount of static electricity is generated on the electrostatic adsorption roller 56. At the same time, the rotating fan blade 55 can generate a certain suction force in the exhaust housing 51, which can suck up some powder generated during the polishing process, and then be quickly captured by the static electricity on the electrostatic adsorption roller 56. When deep hole polishing is performed, since the polishing body 36 is in a stepped shape as a whole, the debris generated during the processing will accumulate on the lower circle. On the upper surface of the column, as the polishing process is completed, the polishing body 36 is controlled to rise, and the polishing body 36 can automatically bring out the debris accumulated on it and will not remain in the processed hole; when polishing, the telescopic rod 34 of the lifting and polishing assembly 3 descends, and at the same time, it can drive the side pressure plate 33 to descend synchronously until the side pressure plate 33 squeezes the storage bag 62. The polishing agent stored in the storage bag 62 can be effectively exported to the polishing body 36 through the polishing agent nozzle 63. As the polishing body 36 enters the deep hole, the polishing agent is brought into the deep hole of the workpiece to assist in polishing.

Open the machine door (1), first install the workpiece, and directly install the workpiece in the installation groove (46) of the rotating disk (41). At this time, the trigger switch (48) is pressed, and the driving motor (471) can be automatically turned on to drive the bidirectional screw (473) to rotate. The two threaded blocks (472) threadedly installed on the bidirectional screw (473) are close to each other, so that the two bidirectional screws (473) are close to each other, and the latch (475) is stuck in the workpiece groove, so that the workpiece can be quickly positioned and clamped; S2, at this time, the driving motor (45) is controlled to work, and the rotating disk (41) is driven to rotate rapidly through the mounting shaft (43), and the workpiece is also rotated rapidly. At this time, the electric push rod (31) of the lifting and polishing assembly (3) is controlled to work, and the polishing body (36) is controlled to descend through the telescopic rod (34), and the polishing body (36) can enter the hole of the rapidly rotating workpiece to perform polishing treatment in the hole; S3. During the polishing process, the position of the polishing body (36) can be adjusted according to the depth of processing required. At the same time, the mounting shaft (43) can also drive the external driving gear (44) to rotate. The driving gear (44) can drive the longitudinal shaft (57) with the driven gear (58) to rotate through meshing. The electrostatic adsorption roller (56) outside the longitudinal shaft (57) and the fan blade shaft (54) at the top rotate, so that the fan blade (55) rotates synchronously in the exhaust housing (51). When the electrostatic adsorption roller (56) rotates, it can quickly release friction with the electrostatic brush (53), so that a large amount of static electricity is generated on the electrostatic adsorption roller (56). At the same time, the rotating fan blade (55) can generate a certain suction force on the exhaust housing (51), which can absorb some powder generated during the polishing process, and then be quickly captured by the static electricity on the electrostatic adsorption roller (56); S4. When deep hole polishing is performed, since the polishing body (36) is in a stepped shape as a whole, the debris generated during the processing will accumulate on the upper surface of the lower cylinder. As the polishing process is completed, the polishing body (36) is controlled to be lifted, and the polishing body (36) can automatically take out the debris accumulated thereon, and will not remain in the processed hole; S5. When polishing is performed, the telescopic rod (34) of the lifting polishing assembly (3) descends, and at the same time, the side pressure plate (33) can be driven to descend synchronously until the side pressure plate (33) squeezes the storage bag (62). The polishing agent stored in the storage bag (62) can be effectively guided to the polishing body (36) through the polishing agent nozzle (63). As the polishing body (36) enters the deep hole, the polishing agent is brought into the deep hole of the workpiece to assist in polishing.
