[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] In one embodiment, such as Figures 1-5 As shown, a deburring device for the inner hole of a motor shaft includes a base plate 1, a support plate 11 symmetrically fixedly connected to the top of the base plate 1, a fixing plate 12 fixedly connected to the top of the support plate 11, a cleaning liquid tank 13 fixedly connected to the top of the base plate 1, a water pump 14 fixedly connected to the top of the cleaning liquid tank 13, the input end of the water pump 14 penetrating through the outer wall of the cleaning liquid tank 13 and communicating with its inner cavity, the output end of the water pump 14 fixedly connected to a connecting pipe 15, the outer wall of the connecting pipe 15 fixedly connected to the inside of the support plate 11, a cleaning mechanism 2 provided on the fixing plate 12, a support mechanism 3 provided at the top of the base plate 1, and a fixing mechanism 4 provided at the bottom of the fixing plate 12. The cleaning mechanism 2 includes a first motor 21, which is fixedly connected to the side wall of the fixed plate 12. The output end of the first motor 21 is fixedly connected to a lead screw 22. The outer wall of the lead screw 22 is rotatably connected to the inside of the fixed plate 12. The outer wall of the lead screw 22 is threadedly connected to a slider 23. The slider 23 is slidably connected to a groove opened on the fixed plate 12. The bottom end of the slider 23 is fixedly connected to a first mounting plate 24. The support mechanism 3 includes a connecting plate 31, the bottom end of the connecting plate 31 is fixedly connected to the top end of the base plate 1, a cylinder 32 is fixedly connected to the side wall of the connecting plate 31, the piston rod of the cylinder 32 passes through the outer wall of the connecting plate 31 and is fixedly connected to an mounting plate 33, a guide rod 34 is slidably fitted in a groove on the mounting plate 33, and one end of the guide rod 34 is fixedly connected to the side wall of the connecting plate 31. The fixing mechanism 4 includes a second mounting plate 41, the top end of which is fixedly connected to the bottom end of the fixing plate 12. A mating plate is fixedly connected to the side wall of the second mounting plate 41 by bolts. The mating plate is connected to the end of the connecting pipe 15 by a flange. A servo motor 42 is fixedly connected to the top end of the second mounting plate 41. A worm gear 43 is fixedly connected to the output end of the servo motor 42. The outer wall of the worm gear 43 is rotatably connected to the inside of the second mounting plate 41. A worm wheel 44 meshes with the outer wall of the worm gear 43.

[0023] In this embodiment, the motor shaft is fixed by the cooperation of the support mechanism 3 and the fixing mechanism 4, which facilitates the subsequent cleaning of the inner hole of the motor shaft. Then, the inner hole of the motor shaft can be cleaned by the cleaning mechanism 2, and the burrs and debris cleaned from the inner hole of the motor shaft can be flushed out by the water pump 14 and the connecting pipe 15.

[0024] In an optional embodiment, such as Figure 3As shown, a second motor 25 is fixedly connected to the side wall of the first mounting plate 24. A cleaning rod 26 is fixedly connected to the output end of the second motor 25. The cleaning rod 26 is rotatably connected to the inside of the first mounting plate 24. Nylon bristles are evenly fixedly connected to the outer wall of the cleaning rod 26. The first motor 21 is started by the PLC, which drives the lead screw 22 to rotate, causing the slider 23 to move axially, which drives the first mounting plate 24 to move synchronously. The first mounting plate 24 drives the cleaning rod 26 to move synchronously, so that the cleaning rod 26 enters the inner hole of the motor shaft. Then the second motor 25 is started, which drives the cleaning rod 26 to rotate. The bristles at the end of the cleaning rod 26 clean the inner hole of the motor shaft and remove the burrs from the inner hole of the motor shaft.

[0025] In an optional embodiment, such as Figure 4 As shown, a bidirectional lead screw 35 is rotatably connected to the top of the mounting plate 33. A connecting block 36 is symmetrically threaded onto the outer wall of the bidirectional lead screw 35. The connecting block 36 is slidably connected to a groove on the mounting plate 33. A clamping plate 37 is fixedly connected to the top of the connecting block 36. The cylinder 32 is started by the PLC, which drives the mounting plate 33 to slide on the guide rod 34. The mounting plate 33 drives the clamping plate 37 to move synchronously. When the clamping plate 37 moves to the end of the motor shaft, the cylinder 32 is closed. Then, the bidirectional lead screw 35 is rotated, which drives the connecting block 36 to move axially, and drives the clamping plate 37 to move synchronously. This allows the two sets of clamping plates 37 to be synchronously aligned and clamp the end face of the motor shaft along the axial direction, thereby supporting and fixing the motor shaft to make it more stable and prevent shaking during subsequent cleaning.

[0026] In an optional embodiment, such as Figure 4 As shown, an arc-shaped rubber pad is fixedly connected to the side wall of the clamping plate 37, and the working surface of the rubber pad is evenly provided with anti-slip ridges. The anti-slip ridges ensure the stability of the clamping plate 37 after clamping the motor shaft and prevent it from rotating when cleaning the inner hole of the motor shaft later.

[0027] In an optional embodiment, such as Figure 5As shown, protrusions 45 are evenly fixedly connected to the inner wall of the worm gear 44, and rollers 46 are attached to the outer wall of the protrusions 45. A connecting rod 47 is fixedly connected to the bottom end of the roller 46. The connecting rod 47 is slidably connected to a groove on the second mounting plate 41. A clamping plate 48 is fixedly connected to the bottom end of the connecting rod 47. Springs 49 are symmetrically fixedly connected to the top end of the clamping plate 48. The top end of the springs 49 is fixedly connected to the inner wall of the second mounting plate 41. The servo motor 42 is started by the PLC to drive the worm gear 43 to rotate, so that the worm gear... 43 drives the worm gear 44 to rotate, which in turn drives the protrusion 45 to rotate, causing the protrusion 45 to contact the roller 46. This causes the roller 46 to gradually move to the protrusion of the protrusion 45, thereby causing the connecting rod 47 to slide in the groove opened on the second mounting plate 41. The connecting rod 47 drives the abutment plate 48 to move, causing the spring 49 to stretch. This causes the abutment plate 48 to clamp the motor shaft, and when clamped, it achieves self-centering operation of the motor shaft, thereby making the motor shaft hole overlap with the through hole of the mating plate, which facilitates the subsequent injection of cleaning fluid into the motor shaft hole.

[0028] In an optional embodiment, such as Figure 5 As shown, a limiting ring is fixedly connected to the side wall of the worm gear 44. The limiting ring is slidably connected to the annular groove opened on the second mounting plate 41. The limiting ring supports and limits the worm gear 44 so that the worm gear 44 will not deviate when it rotates.

[0029] In an optional embodiment, such as Figure 5 As shown, a pressure sensor is installed on the working surface of the clamping plate 48. The pressure sensor, the first motor 21, the second motor 25, the cylinder 32 and the servo motor 42 are electrically connected through a PLC controller. The PLC controls each component so that it can be opened and closed in a timely manner during operation to avoid operational errors.

[0030] The above embodiment discloses a deburring device for the inner hole of a motor shaft. During deburring, the motor shaft is placed inside a second mounting plate 41. Then, a servo motor 42 is started via a PLC, driving a worm gear 43 to rotate. The worm gear 43 drives a worm wheel 44 to rotate, which in turn drives a protrusion 45 to rotate. This causes the protrusion 45 to contact a roller 46, gradually moving the roller 46 to the protrusion of the protrusion 45. This allows a connecting rod 47 to slide within a groove on the second mounting plate 41. The connecting rod 47 moves a clamping plate 48, stretching a spring 49. This clamping plate 48 clamps the motor shaft, achieving deburring of the motor shaft. The self-centering operation of the motor shaft ensures that the motor shaft hole overlaps with the through hole of the mating plate, facilitating the subsequent injection of cleaning fluid into the motor shaft hole. During the clamping process of the clamping plate 48 on the motor shaft, a pressure sensor monitors the clamping force of the clamping plate 48 on the motor shaft in real time. When the pressure reaches a preset threshold, the pressure sensor sends feedback to the PLC, stopping the operation of the servo motor 42, thus completing the fixation of the motor shaft. Then, based on the length of the motor shaft, the PLC starts the cylinder 32, which drives the mounting plate 33 to slide on the guide rod 34. The mounting plate 33 drives the clamping plate 37 to move synchronously. When the clamping plate 37 moves to the end of the motor shaft, the cylinder 32 is closed, and then the shaft rotates. A bidirectional lead screw 35 drives the connecting block 36 to move axially, causing the clamping plates 37 to move synchronously. This ensures that the two sets of clamping plates 37 are synchronously aligned and clamp the motor shaft axially, thus supporting and fixing the motor shaft for greater stability and preventing shaking during subsequent cleaning. Then, the cleaning work can begin. The PLC starts the first motor 21, driving the lead screw 22 to rotate, causing the slider 23 to move axially, which in turn moves the first mounting plate 24 synchronously. The first mounting plate 24 then moves the cleaning rod 26 synchronously, allowing the cleaning rod 26 to enter the inner hole of the motor shaft. Subsequently, the second motor 25 is started, driving the cleaning rod 26 to rotate. The brush bristles at the end clean the inner hole of the motor shaft, removing burrs. Simultaneously, the water pump 14 draws out the cleaning solution from the cleaning solution tank 13 and delivers it to the connecting pipe 15. The connecting pipe 15 then delivers the cleaning solution to the inner hole of the motor shaft, which, together with the brush, cleans the inner hole of the motor shaft and washes away the burrs and debris. In summary, the motor shaft is fixed by the support mechanism 3 and the fixing mechanism 4, facilitating subsequent cleaning of the inner hole of the motor shaft. Afterward, the cleaning mechanism 2 can clean the inner hole of the motor shaft, and the water pump 14 and the connecting pipe 15 can wash away the burrs and debris cleaned from the inner hole of the motor shaft.

[0031] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
