Description

Technical Field

[0001] The invention relates to the technical field of metal processing, and in particular to a differential shaft platform edge processing device. Background Art

[0002] The differential is usually a device used in automobiles that has power transmission and power distribution functions. Its function is to automatically adjust the speed of the inner and outer wheels when the car is turning to prevent the inner and outer wheels from slipping, allowing the car to turn smoothly.

[0003] The interior of the differential is mainly composed of half shafts on both sides, bevel gears installed at the ends of the half shafts, a shaft body installed in the middle of the housing, and two bevel gears rotatably connected to the two ends of the shaft body. In order to ensure lubrication between the bevel gears and the shaft body, it is necessary to open a flat platform on the outside of the shaft body for introducing lubricating oil, so that the lubricating oil inside the differential housing can be evenly introduced into the gap between the bevel gear and the shaft body through the flat platform, thereby reducing the wear of parts in the differential.

[0004] In the field of modern machining, a plane is usually milled directly on the outside of the shaft by a milling machine or a drilling machine, for example:

[0005] After searching, the Chinese patent with publication number: CN117226148A discloses a motor shaft keyway processing machine, including a workbench and a drilling rig, a clamping table is arranged on the workbench, a pressure block is arranged on the clamping table, the pressure block is slidably connected to the clamping table, and the pressure block slides vertically along the clamping table, and a top support assembly for driving the pressure block to slide is also arranged on the workbench, a limit block is arranged at the position of the clamping table corresponding to the clamping table, the limit block is arranged on the upper side of the pressure block, and when the pressure block moves upward, it can cooperate with the limit block to clamp the motor shaft, and a clearance groove for the drill bit of the drilling rig to pass through is opened on the limit block; both ends of the pressure block in the length direction are provided with inclined surfaces, and the side of the inclined surface close to the center of the pressure block is higher than the side away from the center of the pressure block, and when the pressure block moves upward, an inclined groove for debris to pass through is left between the inclined surface and the limit block.

[0006] Based on the above search and combined with the actual mechanical processing technology, it is found that although a plane can be milled out on the outside of the shaft body by a milling machine or a drilling machine, smooth fillets cannot be machined on both sides of the plane, because both sides of the plane have relatively sharp edges with poor smoothness. Therefore, the stress on the edges is very concentrated. When the shaft body of the differential is subjected to a large force, the sharp position is prone to wear and cracks. In addition, the sharp edges will affect the uniform introduction of lubricating oil into the gap between the inner side of the bevel gear and the outer side of the shaft body, thereby further aggravating the wear of the differential parts.

DETAILED DESCRIPTION

[0028] The present invention is described in detail below, and the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The present invention provides a differential shaft platform edge processing device through improvement. The technical solution of the present invention is:

[0030] like Figures 1 to 7 As shown, an embodiment of the present invention provides a differential shaft platform edge processing device, including a bottom plate 1 and two vertical plates 2, a fixed housing 108 is movably arranged between the two vertical plates 2 through a reciprocating mechanism, and a shaft fixing mechanism is arranged inside the fixed housing 108; the shaft fixing mechanism includes three telescopic rods 109 slidably inserted inside the fixed housing 108 and a pushing mechanism for driving the three telescopic rods 109 to merge; a turning mechanism is arranged between the two vertical plates 2; the turning mechanism includes two arc grooves 3 opened on the two vertical plates 2, the inner sides of the two arc grooves 3 are slidably connected with arc sliders 4, and between the two arc sliders 4 A main shaft 5 is rotatably connected therethrough, and two sleeves 6 are fixed to the outer side of the main shaft 5. A turning tool 8 is installed on one side of the two sleeves 6 through a first bent rod 7. A driving mechanism is arranged between the main shaft 5 and one of the arc-shaped sliders 4, and a shifting mechanism for adjusting the position of the main shaft 5 is arranged between the main shaft 5 and the base plate 1; the shifting mechanism includes two first electric cylinders 203 and two reversing rods 201 rotatably connected to the upper side of the base plate 1, and the telescopic ends of the two first electric cylinders 203 are respectively rotatably connected to the outer sides of the reversing rods 201 at corresponding positions, and the upper ends of the two reversing rods 201 are provided with open grooves 202 that can be slidably connected to the outer side of the main shaft 5.

[0031] Furthermore, the driving mechanism includes a driven gear 20 fixed to one end of the main shaft 5 and a main motor 19 installed on one side of one of the arc-shaped sliders 4, and a driving gear 21 meshing with the driven gear 20 is fixed to the driving end of the main motor 19;

[0032] The main motor 19 drives the driving gear 21 to rotate, and the driving gear 21 drives the driven gear 20 to rotate, thereby driving the main shaft 5 of the turning mechanism to rotate, and the main shaft 5 drives the first bending rod 7 and the turning tool 8 to rotate, and the side edge of the shaft plane is turned and rounded.

[0033] Furthermore, the reciprocating mechanism includes two guide rods 101 fixed between the two vertical plates 2, a rotating rod 102 rotatably connected between the two vertical plates 2, and a reciprocating drive motor 103 installed on one side of one of the vertical plates 2, the driving end of the reciprocating drive motor 103 is fixedly connected to one end of the rotating rod 102, a moving plate 106 is slidably connected to the outer side of the two guide rods 101, a cylindrical reciprocating cam 104 is fixed at the position of the outer side of the rotating rod 102 corresponding to the moving plate 106, a first sliding pin 107 is movably provided on the upper side of the moving plate 106, the first sliding pin 107 is adapted to the cam groove on the outer side of the cylindrical reciprocating cam 104, and the lower side of the moving plate 106 is fixed to the fixed shell 108;

[0034] Through the reciprocating mechanism and the shaft fixing mechanism therein, the shaft to be processed can be fixed and driven to reciprocate in the horizontal direction, so that the turning tool 8 can uniformly turn the side edges of the shaft plane in turn, ensuring the smoothness of the rounded corners of the side edges of the shaft plane.

[0035] Furthermore, the pushing mechanism includes a rotating ring 111 rotatably connected to the inner side of the fixed housing 108, a fixed motor 114 installed on the inner side of the fixed housing 108, and three second sliding pins 110 that penetrate and rotatably connect to one end of the three telescopic rods 109. A worm 115 is fixed to the driving end of the fixed motor 114. A meshing tooth 112 that can mesh with the worm 115 is provided at one side edge of the rotating ring 111. An arc-shaped push plate 113 is fixed to one side of the rotating ring 111 at a position corresponding to each second sliding pin 110.

[0036] The pushing mechanism is used to push the three telescopic rods 109 to move synchronously toward the shaft body, thereby fixing the shaft body and ensuring the stability of the shaft body during the rounding process, thereby ensuring the processing accuracy of the rounded corners.

[0037] Furthermore, arc-shaped clamping plates 116 are fixed to opposite ends of the three telescopic rods 109, and one side of each arc-shaped clamping plate 116 can fit with the outer side of the shaft body to be fixed;

[0038] The arc-shaped clamping plate 116 can fully fit with the outer side of the shaft body, thereby improving the fixing reliability of the shaft body.

[0039] Further, a second curved rod 9 is fixed to one side of the outer side of the two sleeves 6 relative to the first curved rod 7, and a fixed pulley 11 that does not contact the main shaft 5 is fixed to one side of the two arc-shaped sliders 4, and a transmission shaft 10 is movably provided through one end of the two second curved rods 9, a grinding wheel 14 is provided at one end of the two transmission shafts 10, and a movable pulley 12 is fixed to the other end of the two transmission shafts 10, and the two movable pulleys 12 are respectively connected to the outer sides of the two fixed pulleys 11 through a transmission belt 13;

[0040] When the second curved rod 9 drives the transmission shaft 10 to rotate around the main shaft 5, the transmission action of the fixed belt pulley 11 and the transmission belt 13 can drive the movable belt pulley 12 and the transmission shaft 10 to rotate inside the second curved rod 9, thereby driving the grinding wheel 14 at the end of the transmission shaft 10 to rotate. Therefore, the grinding wheel 14 can rotate at a relatively high speed while rotating around the main shaft 5. After the turning tool 8 turns the side edge of the shaft plane once, certain burrs will be generated on the side edge of the plane. When the grinding wheel 14 passes the burr position, the grinding wheel 14 rotating at a relatively high speed can grind the burr, thereby further improving the smoothness of the fillet of the side edge of the shaft plane and improving the machining accuracy.

[0041] Furthermore, a bracket 301 is fixed at the middle position of one side of the bottom plate 1, a second electric cylinder 302 is installed at a position where the upper end of the bracket 301 is aligned with the fixed housing 108, a translation plate 303 is fixed to the telescopic end of the second electric cylinder 302, two milling motors 304 are installed at both ends of the translation plate 303, and a milling tool 305 is installed at the driving end of the two milling motors 304;

[0042] The two milling motors 304 drive the two milling cutters 305 to rotate. At the same time, the telescopic end of the second electric cylinder 302 extends to drive the translation plate 303 and the two milling motors 304 to move toward the direction of the shaft body. The two milling motors 304 drive the two rotating milling cutters 305 to contact the outside of the shaft body. The rotating milling cutters 305 can mill the required plane on the outside of the shaft body.

[0043] Working principle: When in use, the shaft body in the differential is set inside the fixed housing 108 of the reciprocating mechanism, and then the fixed motor 114 of the shaft body fixing mechanism is controlled to run to drive the worm 115 to rotate. The worm 115 can engage with the meshing teeth 112, thereby driving the rotating ring 111 to rotate a certain angle. The rotating ring 111 drives multiple arc-shaped push plates 113 at one end thereof to rotate. Each arc-shaped push plate 113 can apply a thrust to the second sliding pin 110 at the corresponding position. The three second sliding pins 110 can drive the three telescopic rods 109 to extend outwards under the thrust, thereby driving the three arc-shaped clamping plates. 116 is pressed on the outer side of the shaft body to fix the shaft body. After the fixing is completed, the two milling motors 304 can be controlled to run and drive the two milling cutters 305 to rotate. At the same time, the telescopic end of the second electric cylinder 302 is controlled to extend to drive the translation plate 303 and the two milling motors 304 to move toward the direction of the shaft body. The two milling motors 304 drive the two rotating milling cutters 305 to contact the outer side of the shaft body. The rotating milling cutters 305 can mill the required plane on the outer side of the shaft body. The plane can be used to pass lubricating oil to introduce the lubricating oil into the gap between the shaft body and the gears on the outer side thereof (such as Figure 6 shown);

[0044] After the plane milling of the outer side of the shaft is completed, adjust the angle of the shaft so that the milled plane is vertically upward. Figure 1 As shown, the telescopic end of the first electric cylinder 203 of the shifting mechanism is then controlled to retract and extend respectively. The retracting and extending of the telescopic end of the first electric cylinder 203 can push the two reversing rods 201 to rotate a certain angle in different directions. The two reversing rods 201 can move the main shaft 5 through the two opening grooves 202 to drive the two arc-shaped sliders 4 to slide inside the two arc-shaped grooves 3. When the telescopic end of the first electric cylinder 203 is at the retracting limit and the extending limit, the two ends of the main shaft 5 can be respectively located at one end and the other end of the inner side of the two arc-shaped grooves 3, so that the two arc-shaped sliders 4 are respectively located at one end and the other end of the two arc-shaped grooves 3;

[0045] When the two arc-shaped sliders 4 and a main shaft 5 are located at one end of the two arc-shaped slots 3, the main motor 19 of the driving mechanism drives the driving gear 21 to rotate, the driving gear 21 drives the driven gear 20 through the teeth, and the driven gear 20 drives the main shaft 5 of the turning mechanism to rotate. The main shaft 5 rotates through the two sleeves 6 on its outer side to drive the two first curved rods 7 to rotate, and the two first curved rods 7 respectively drive the two turning tools 8 to rotate. The two turning tools 8 can turn one side of the two planes and mill the side edges into fillets. The two turning tools 8 can turn one side of the shaft body plane once per rotation. At the same time, the reciprocating drive motor 103 of the reciprocating mechanism drives the rotating rod 102 and the cylindrical reciprocating cam 1 04 rotates, when the cylindrical reciprocating cam 104 rotates, the sliding cooperation between the cam groove on its outer side and the first sliding pin 107 can drive the moving plate 106 to reciprocate along the outer side of the guide rod 101, thereby driving the fixed housing 108 and the shaft body fixed on the inner side to reciprocate along the length direction of the guide rod 101, so that each turning tool 8 can turn one side of the outer plane of the shaft body in turn, so that the fillet size of the plane side is more accurate, which can effectively eliminate the concentrated stress on the plane side of the shaft body, ensure the rigidity of the shaft body, and at the same time, the uniform and smooth fillet structure of the plane side can well guide the lubricating oil, so that the lubricating oil is more evenly distributed in the gap between the shaft body and the gear, reducing the wear of the differential;

[0046] When the rounded corner processing of one side of the shaft plane is completed, the position of the main shaft 5 is adjusted by the shifting mechanism, so that the main shaft 5 and the two arc-shaped slide blocks 4 are moved to the other end of the two arc grooves 3. At this time, the center position of the two first bending rods 7 and the two turning tools 8 is changed. At this time, the two turning tools 8 can turn the other side of the shaft plane when rotating, so that the other side of the shaft plane can be turned into a rounded corner of the same size, thereby improving the processing efficiency and processing accuracy;

[0047] The main shaft 5 of the turning mechanism drives the two sleeves 6 to rotate, and can also drive the two second curved rods 9 to rotate synchronously with the two first curved rods 7. One end of the two second curved rods 9 is provided with a transmission shaft 10, and the two fixed pulleys 11 are respectively fixed to the outside of the two arc-shaped sliders 4, so the two fixed pulleys 11 do not rotate. When the second curved rod 9 drives the transmission shaft 10 to rotate around the main shaft 5, the transmission effect of the fixed pulley 11 and the transmission belt 13 can drive the movable pulley 12 and the transmission shaft 10 to rotate inside the second curved rod 9, thereby driving the grinding wheel 14 at the end of the transmission shaft 10 to rotate. Therefore, the grinding wheel 14 can also rotate around the main shaft 5. In order to rotate at a relatively high speed, the main shaft 5 drives the two turning tools 8 and the two grinding wheels 14 at both ends to alternately rub the side edges of the shaft plane. Every time the main shaft 5 rotates one circle, the turning tool 8 and the grinding wheel 14 can rub the side edges of the shaft plane once respectively. After the turning tool 8 turns the side edge of the shaft plane once, certain burrs will be generated on the side edge of the plane. When the grinding wheel 14 passes the burr position, the grinding wheel 14 rotating at a relatively high speed can grind away the burrs, thereby further improving the smoothness of the fillet of the side edge of the shaft plane, improving the machining accuracy, allowing the lubricating oil to be evenly distributed on the shaft plane, and at the same time, the lubricating oil can be evenly introduced into the gap between the shaft and the gear.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
