Description

It is an important part manufactured through steps such as cutting, rough turning, semi-finish turning, milling slots, heat treatment, and precision grinding. It is widely used in production and life. Usually, the output end of the motor is a rectangular structure. The output end of the motor is generally the part used by the motor to connect with external equipment. Usually, fine processing such as drilling is required for the output end of the motor to facilitate the subsequent connection between the motor and external equipment.

When processing motor shafts of different batches and specifications, it is necessary to replace the fixtures for processing, which affects the processing progress.

[0018] Please refer to Figures 2-5 As shown in Figures 2-5 , the fixture 3 includes a transverse clamping portion and a longitudinal clamping portion. The longitudinal clamping portion is disposed on the transverse clamping portion. The transverse clamping portion is used to fixedly clamp the diameter direction of the horizontal axis, and the longitudinal clamping portion is used to clamp and fix the length direction of the horizontal axis. The transverse clamping portion includes a base 31. A groove is formed in the base 31. A lead screw 32 and a movable block 34 are disposed in the groove. The lead screw 32 is connected to the base 31 by a bearing. The lead screw 32 is threadedly connected to the movable block 34. A stopper is disposed at the left end of the base 31. A fixing block 33 is screwed onto the stopper. Both the stopper and the fixing block 33 are hollow structures. A rotating shaft is connected to the stopper by a bearing. The rotating shaft is connected to the lead screw 32 by a belt pulley drive. The rotating shaft passes through the stopper and the fixing block 33 and is connected to the fixing block 33 by a bearing. A lifting block 35 is slidably connected inside the fixing block 33. A hollow groove is formed inside the lifting block 35. The rotating shaft in the hollow groove is connected to the lifting block 35 by a gear drive combined with a gear-rack drive.

[0019] The longitudinal clamping portion includes a sliding rod 37. Sliding grooves are formed on both sides of the base 31. The sliding rod 37 is disposed in the sliding groove and is slidably connected to the base 31. Two groups of sliding rods 37 are disposed in each sliding groove. A plurality of protrusions 38 are fixedly connected to the end of the sliding rod 37 close to the base 31. A plurality of grooves matching the protrusions 38 are disposed on the base 31 close to the sliding rod 37. A sliding groove is formed at the end of the sliding rod 37 away from the base 31. A first spring 39 is disposed in the sliding groove. One end of the first spring 39 is fixedly connected to the sliding rod 37, and the other end of the first spring 39 is connected to a first connecting rod 310. The first connecting rod 310 is L-shaped and internally fixedly connected with the first spring 39. A first guiding rod 312 is fixedly connected to the side of the base 31. The sliding rod 37 is sleeved on the first guiding rod 312. The first guiding rod 312 is used to limit the horizontal position of the sliding rod 37 and ensure the moving direction of the sliding rod 37. Three guiding rods 313 are fixedly connected to the left first connecting rod 310. The right first connecting rod 310 is sleeved on the guiding rods 313. A movable plate 311 is sleeved on the guiding rods 313. The guiding rods 313 are used to limit and guide the position of the first connecting rod 310 and facilitate the adjustment of the position of the movable plate 311 to ensure that the movable plate 311 can contact the end of the rotating shaft and limit the length direction of the rotating shaft.

[0020] In actual operation, the end of the lead screw 32 is connected to a handwheel or a motor. The initial state of the fixture 3 is that the lifting block 35 is in the raised state, the movable block 34 is located on the right side of the base 31, and the right connecting rod 310 is located at the right end of the chute. When in use, the staff adjusts the positions of the right connecting rod 310 and the movable plate 311 according to the diameter of the rotating shaft, and then successively pulls the movable plates 311 on both sides of the base 31, thereby pulling the connecting rod 310 to drive the first spring 39 to stretch. Place the connecting rod 310 between the fixed block 33 and the movable block 34 on the base 31 so that the connecting rod 310 fits against the end of the rotating shaft, fixing the length direction of the rotating shaft. Here, under the pulling force of the first spring 39, it can ensure that the extended lengths of the connecting rods 310 on both sides of the base 31 are the same, and at the same time, the convex block 38 at the end of the sliding rod 37 is located in the groove on the base 31 to prevent the sliding rod 37 from moving during processing; then drive the lead screw 32 to rotate forward manually or automatically, drive the movable block 34 to approach the rotating shaft, and clamp the rotating shaft between the fixed block 33 and the movable block 34. The forward-rotating lead screw 32 drives the rotating shaft to rotate through a belt drive, and the rotating shaft then drives the lifting block 35 to descend through a gear drive combined with a rack and pinion drive to fix the rotating shaft; when the rotating shaft has a large diameter, the moving distance of the movable block 34 driven by the lead screw 32 is small, and at the same time, the descending height of the lifting block 35 driven is small. At this time, the rotating shaft contacts the lifting block 35 and the movable block 34, and the bottom of the rotating shaft still contacts the top of the base 31, having good clamping stability, thereby improving the applicability of the device, avoiding both the fixture 3 being unable to clamp a rotating shaft with a large diameter and the rotating shaft being suspended when clamping a rotating shaft with a small diameter, which affects the subsequent processing quality.

[0021] Please refer to Figure 1 , Figure 6 and Figure 7 , the first processing part 4 includes a connecting rod 41. The connecting rod 41 is arranged on the top of the support 1. The end of the connecting rod 41 is fixedly connected with a connecting cylinder 43. A second driving part 42 is arranged on the top of the connecting cylinder 43. A first cutter 44 is arranged at the bottom of the connecting cylinder 43. The output end of the second driving part 42 is connected with the first cutter 44. The second driving part 42 is used to drive the first cutter 44 to rotate.

[0022] The second processing part 5 includes a cylinder 51. The cylinder 51 is fixed on the side of the connecting cylinder 43. The output end of the cylinder 51 is fixedly connected with a third driving part 52. The output end of the third driving part 52 is connected with a second cutter 53. The cylinder 51 is used to drive the third driving part 52 to lift and lower. The third driving part 52 is used to drive the second cutter 53 to rotate.

[0023] A trachea 9 is connected to the side of the connecting cylinder 43. The trachea 9 is connected with an air pump.

[0024] In actual operation, both the second driving part 42 and the third driving part 52 are driven by motors. The first tool 44 is preferably a milling cutter, and the second tool 53 is preferably a chamfering tool. The second driving part 42 drives the first tool 44 to rotate. After milling the keyway at the top of the rotating shaft, the first driving part 2 adjusts the position of the rotating shaft so that the second tool 53 is located directly above the keyway. The air cylinder 51 extends, driving the third driving part 52 to descend. At the same time, the third driving part 52 starts to drive the second tool 53 to rotate, chamfering and polishing the edge of the keyway on the rotating shaft. The air pump starts to pump compressed air into the air pipe 9, enabling the air pipe 9 to blow away the processed debris, facilitating subsequent detection. Thus, two production processes can be completed using the same fixture 3 at the same processing station.

[0025] Please refer to Figure 1 and Figure 7 , the first detection component 6 includes a connecting plate 61 and a camera 62. The connecting plate 61 is fixed to the top of the connecting cylinder 43, and the camera 62 is fixed to the bottom right end of the connecting plate 61. The camera 62 is used to photograph the keyway processed on the rotating shaft.

[0026] Please refer to Figure 1 and Figure 8 , there are two sets of the second detection components 7, which are respectively located between both sides of the base 31 and the movable plate 311. The second detection component 7 includes a support base 71, a detection table 73, and a pressure sensor 75. The top of the support base 71 is fixedly connected with a fixed cylinder 72. The detection table 73 is arranged inside the fixed cylinder 72. The top of the detection table 73 is slightly higher than the top of the base 31. The bottom of the detection table 73 is fixedly connected with a second spring 74. The second spring 74 is sleeved outside the fixed cylinder 72, and the other end of the second spring 74 is fixedly connected with the top of the support base 71. The pressure sensor 75 is fixed at the bottom of the support base 71 corresponding to the position of the detection table 73. The pressure sensor 75 is used to sense the pressure value received by the detection table 73.

[0027] The first driving part 2 is a three-axis driving structure. The base 31 and the support base 71 are fixed to the top of the first driving part 2. The first driving part 2 is used to drive the fixture 3 and the second detection component 7 to move forward, backward, up, down, left, and right.

[0028] In actual operation, when the fixture 3 does not clamp the rotating shaft, the top of the detection table 73 is slightly higher than the top of the base 31. After clamping the rotating shaft to be processed on the fixture 3, both ends of the rotating shaft come into contact with the detection table 73. The second spring 74 is used for buffering and adjusting the position of the detection table 73 according to the height of the rotating shaft, enabling the detection table 73 to contact the rotating shaft. The pressure sensor 75 detects the pressure values at both ends.

[0029] Please refer to Figure 9 , a protective frame 8 is fixedly connected to the top of the first driving part 2. The protective frame 8 is used to be closed during the processing of the rotating shaft to prevent the processed debris from harming the staff.

[0030] The motor shaft processing equipment further includes a processing system, which includes a collection module, an analysis module, a control module, and an alarm module. The collection module is electrically connected to the first detection component 6 and the second detection component 7. The collection module is used to collect the pictures of the keyways processed on the shaft to be detected and the heights of both ends of the shaft to be processed. The analysis module is used to analyze the heights of both ends of the shaft and identify and judge the processing conditions of the keyways on the shaft. The control module is electrically connected to the first driving part 2, the first processing part 4, and the second processing part 5. The control module is used to control the fixture 3 to move forward, backward, up, down, left, and right, and control the first processing part 4 and the second processing part 5 to process the shaft. The alarm module is used to give an alarm prompt when the processing is abnormal.

[0031] Processing method of the motor shaft processing equipment: Step 1: Clamp the motor shaft to be processed and detect and analyze the heights of both ends of the motor shaft.

[0032] Specifically, manually or using a robot, install the motor shaft to be processed on the fixture 3. The collection module collects and records the pressure data detected by the second detection component 7 and feeds it back to the analysis module. The left-end pressure data detected by the second detection component 7 is denoted as and the right-end pressure data detected by the second detection component 7 is denoted as An allowable pressure error set according to the pressure sensor 75 is set in the analysis module, and the allowable pressure error is denoted as A.

[0033] When , the pressure data detected by the two second detection components 7 are similar, indicating that the shaft fixed and clamped by the fixture 3 is in a horizontal state at this time and subsequent processing and detection can be carried out. When , it is an ideal state.

[0034] When or , the pressure data detected by the two second detection components 7 differ greatly, indicating that the shaft fixed and clamped by the fixture 3 is in an inclined state at this time. If or is zero, it is caused by abnormal clamping, which is fed back to the alarm module for an alarm prompt. Re-clamp the shaft to be processed. If it is repeated only once and the result remains unchanged after repetition, it is caused by shaft deformation, which is fed back to the alarm module for an alarm prompt, and replace the shaft to be processed; if or is not zero, it is caused by shaft deformation, which is fed back to the alarm module for an alarm prompt, and replace the shaft to be processed.

[0035] Step 2: Process the keyway on the shaft and detect the processing condition of the keyway.

[0036] Specifically, the control module controls the driving part 1 to drive the rotating shaft to be processed on the fixture 3 to be located directly below the first tool 44. Then, it controls the driving part 2 to start, driving the rotating shaft of the first tool 44. After that, it controls the driving part 1 to move left and right, up and down to process the keyway. After the processing is completed, the control module controls the driving part 1 to move downward first and then to the right, so that the keyway is located directly below the camera 62. The acquisition module acquires the captured image of the camera 62 and feeds it back to the analysis module. The analysis module identifies the center line of the keyway, the axis of the rotating shaft, the length of the keyway, the length between one end of the keyway close to the end of the rotating shaft and the end of the rotating shaft, and the smoothness of the bottom. The center line of the keyway is the symmetric center of the long side of the keyway. The length of the keyway is denoted as L', and the length between one end of the keyway close to the end of the rotating shaft and the end of the rotating shaft is denoted as D'.

[0037] In the analysis module, there are set the standard length and length error value of the keyway. The standard length is denoted as L, and the length error is denoted as ±n. In the analysis module, there are also set the standard distance and distance error between one end of the keyway close to the end of the rotating shaft and the end of the rotating shaft. The standard distance is denoted as D, and the distance error is denoted as ±m.

[0038] When the center line of the keyway is parallel to the axis of the rotating shaft, the shape of the keyway is good and subsequent detection can be carried out.

[0039] Case 1: When and , it means that the position of the processed keyway meets the production requirements. When L' = L and D' = , it is the ideal state; Case 2: When , it means that the distance is normal, but the length of the keyway is small. It is fed back to the control module, and this step is repeated and the control is to increase the lateral movement distance during the processing of the driving part 1. The increased lateral movement distance is . It is repeated at most three times. When a keyway with a length that meets the requirements is processed, the accumulated increased lateral movement distances during the multiple repeated processings are used to replace the first lateral movement distance of the driving part 1. If after repeating three times, still appears, it is fed back to the alarm module, and the staff will repair the processing equipment; Case 3: When , it means that the distance is normal, but the length of the keyway is large. This rotating shaft is scrapped, and the rotating shaft to be processed is replaced and fed back to the control module. The lateral movement distance during the processing of the driving part 1 is reduced. The reduced lateral movement distance is . At most, two groups of motor rotating shafts to be processed are connected and replaced. When a keyway with a length that meets the requirements is processed, the first lateral movement distance of the driving part 1 during the first processing is subtracted by the reduced lateral movement distance and then used to replace the first lateral movement distance of the driving part 1. If after reducing the lateral movement distance of the driving part 1 twice, still appears, it is fed back to the alarm module, and the staff will repair the processing equipment; Case 4: When , , the keyway length is normal, but the distance between the keyway and the end of the rotating shaft is small. The rotating shaft is scrapped, the rotating shaft to be processed is replaced, and it is fed back to the control module to increase the moving distance of the first driving part 2 driving the first tool 44, so as to increase the distance between the first tool 44 and the end of the rotating shaft when cutting. The increased distance is . At most, two groups of motor rotating shafts to be processed are connected and replaced. When the keyway with the distance between the keyway and the end of the rotating shaft meeting the requirements is processed, the accumulated increased cutting distances of the first driving part 2 multiple times are used to replace the distance between the first driving part 2 and the end of the rotating shaft when cutting. If still occurs after two times, it is fed back to the alarm module, and the processing equipment is repaired by the staff; Case 5: When , , the keyway length is normal, but the distance between the keyway and the end of the rotating shaft is large. The rotating shaft is scrapped, the rotating shaft to be processed is replaced, and it is fed back to the control module. The control method is similar to that in Case 4. The difference is that the moving distance of the first driving part 2 driving the first tool 44 is reduced, so as to reduce the distance between the first tool 44 and the end of the rotating shaft when cutting.

[0040] In other cases, the rotating shaft and the processing are abnormal. The rotating shaft is scrapped, the rotating shaft to be processed is replaced, and reprocessing is carried out. At most, two groups of motor rotating shafts to be processed are connected and replaced. If the processing is still abnormal, it is fed back to the alarm module, and the processing equipment is repaired by the staff; When the keyway that meets the requirements is processed, if the bottom of the keyway is smooth, subsequent processing can be carried out. If the bottom of the keyway is not smooth and there are patterns, it is fed back to the alarm module, and the staff adjusts the movement speed of the first driving part 2 during the processing or replaces the first tool 44.

[0041] When the keyway center line is not parallel to the axis of the rotating shaft, the keyway is deformed during processing. The rotating shaft is scrapped, the rotating shaft to be processed is replaced, and it is fed back to the control module to increase the moving distance of the lead screw 32 driving the movable block 34 to ensure that the fixture 3 always clamps the rotating shaft to be processed. If three groups of rotating shafts with the keyway center line not parallel to the axis of the rotating shaft continuously appear, it is fed back to the alarm module, and the processing equipment is repaired by the staff.

[0042] Step 3: Chamfer and deburr the keyway processed normally.

[0043] Specifically, the control module drives the first driving part 2 to drive the rotating shaft on the fixture to move, and at the same time controls the third driving part 52 to start to chamfer and deburr the keyway. In this step, the moving distance of the first driving part 2 driving the second tool 53, that is, the distance between the second tool 53 and the end of the rotating shaft when cutting, is the adjusted distance in Step 2, and the lateral moving distance of the first driving part 2 driving the rotating shaft during processing is also the adjusted distance in Step 2.

[0044] Through the above steps, the motor shaft with different diameters and lengths can be fixedly clamped, with wide applicability and good stability. At the same time, it ensures that the machining is carried out after the shaft is clamped and balanced, improving the machining quality. It can also detect the keyway and chamfer and deburr in time after the machining is completed, simplifying the machining process, avoiding repeated clamping, and improving the machining efficiency and accuracy.
