Description

Technical Field

[0001] The present invention belongs to the technical field of differential housing grinding devices, and particularly relates to a differential housing grinding device. Background Art

[0002] The differential is a key component in the vehicle drive system, mainly used to coordinate the rotational speed differences between the left and right wheels when the vehicle turns, ensuring smooth vehicle steering and optimizing power transmission. The differential housing is the core load-bearing component of the differential system, responsible for protecting the internal gear mechanism, transmitting torque, and ensuring the connection between the differential and the transmission system.

[0003] A grinding device is a piece of equipment that removes excess material through the relative movement of abrasive grains and the workpiece surface to achieve precision machining. It is widely used in fields such as metal processing, tool manufacturing, and automotive component production. Its core principle is to utilize the micro-cutting action of abrasive grains to grind, polish, or perform ultra-precision machining on the workpiece through a high-speed rotating grinding wheel or grinding head.

[0004] The authorized publication number "CN115533645A" discloses "an automated grinding system for a new energy vehicle differential housing, which relates to the technical field of differential processing, and includes a base, a lifting mechanism, a fixing mechanism, and a grinding mechanism. The lifting mechanism is arranged on the base, the fixing mechanism is arranged on the base, and the grinding mechanism is arranged on the lifting mechanism; by setting the fixing mechanism, the present invention can clamp different positions of the automotive differential housing to facilitate grinding different positions of the differential housing; by setting the grinding mechanism, the present invention can simultaneously grind the two end faces of the differential housing flange, and can simultaneously adjust the grinding area, and can also change the thickness of the grinding plate to grind different positions of the differential; by setting the grinding mechanism, the present invention can automatically adjust the angle of the grinding disc to facilitate grinding the round holes at any position on the differential housing, which is convenient to use".

[0005] Through the above patent, by setting the grinding mechanism, the angle of the grinding disc can be automatically adjusted to facilitate grinding the round holes at any position on the differential housing, which is convenient to use. However, in the actual grinding process, due to the non-uniform shapes of the holes on the curved surfaces of different models of differential housings, the existing grinding devices cannot adaptively adjust the deflection angle of the grinding head for different models of differential housings, resulting in the grinding device being unable to simultaneously meet the grinding requirements of the curved surface holes of different models of differential housings. When the curved surface holes of different models of differential housings are ground alternately, the production efficiency of the differential housing is reduced. At the same time, the grinding head without an automatic adjustment function causes burrs to remain on the edges of the curved surface holes of the differential housing, resulting in an increase in the rework rate of defective differential housings and a decrease in the yield rate of the differential housing. Therefore, we propose a differential housing grinding device. Summary of the Invention

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. In this solution, the output end of the second electric push rod contracts to pull the ratchet pawl away from the ratchet wheel, releasing the engagement and locking between the pawl and the ratchet wheel. The deflection motor is powered on and started, and the output end of the deflection motor drives the second driving gear to rotate. The second driving gear drives the second driven gear to rotate through meshing with the second driven gear. The second driven gear drives the driving rod and the ratchet wheel to deflect, so that the ratchet wheel and the driving rod deflect synchronously. The driving rod pulls the pull rod, and the pull rod pulls the driven rod, so that the driven rod and the driving rod deflect synchronously. The driven rod drives the deflection rod to deflect, so that the deflection rod drives the grinding machine to deflect up and down. At the same time, the stepping motor is powered on and started, and the output end of the stepping motor drives the first driving gear to rotate. The first driving gear drives the first driven gear to rotate through meshing with the first driven gear. The first driven gear drives the rubber turntable to rotate, and the rubber turntable drives the housing to deflect axially. Then, the grinding machine moves in a circle in the curved hole of the housing. At the same time, the camera is used to detect in real time whether the grinding machine fits the edge of the curved hole, and is used to adjust the three-dimensional coordinate parameters, so that the grinding machine performs circular cutting on the edge of the curved hole of the housing, meeting the grinding requirements of different specifications of differential housing holes, facilitating the grinding operation of different specifications of differential housing curved holes on a single production line, improving the cross-grinding efficiency of different specifications of differential housing holes, and improving the production efficiency of the differential housing.

[0024] 2. In this solution, during the circular grinding process, the up and down deflection angle of the grinding machine and the vertical axial deflection of the housing make the grinding head of the grinding machine fit the edge of the curved hole of the housing. At the same time, the camera performs real-time three-dimensional data detection on the grinding machine. Then, the grinding head has the ability of automatic adjustment, realizing deburring of the edge of the curved hole of the housing. Through the automatic adjustment of the grinding head, the generation of burr residues at the edge of the curved hole of the differential housing is avoided, the defective rework rate of the differential housing is reduced, and the yield rate of the differential housing is improved.

[0025] 3. In this solution, the conical pressing block clamps and fixes the housing by approaching the rubber turntable, and at the same time, the conical pressing block can rotate, so that the conical pressing block and the rubber turntable can drive the housing to rotate synchronously, avoiding the housing from skewing, preventing misalignment during the grinding of the housing by the grinding machine, eliminating the risk of tool collision and damage between the grinding machine and the housing, and improving the use safety of the grinding device.

[0026] 4. During the deflection of the housing, the stepping motor is powered on and started, and the output end of the stepping motor drives the first driving gear to rotate. The first driving gear drives the first driven gear to rotate through meshing with the first driven gear. The first driven gear drives the rubber turntable to rotate, and then drives the housing to deflect, so that the holes on the curved surface of the housing correspond to the grinding machine. By deflecting the housing, the edge of the curved hole of the housing fits the grinding head of the grinding machine, enabling the grinding machine to finely grind the curved hole of the housing and improving the grinding accuracy of the grinding device.

The second driven gear 32 drives the active rod 30 to deflect, and then provides power for the up and down deflection of the grinding machine 26.

[0060] The limiting component includes a ratchet cover 35, a ratchet 36, a pawl 37 and a second electric push rod 38. The ratchet cover 35 is sleeved on the other end of the rotating shaft of the second driven gear 32. The ratchet cover 35 is fixedly connected to the side end of the second gear cover 31. The ratchet 36 is fixedly connected to the other end of the rotating shaft of the second driven gear 32, and the ratchet 36 is located between the inner walls of the ratchet cover 35. The pawl 37 is rotatably connected between the inner walls of the ratchet cover 35. The second electric push rod 38 is fixedly connected to the side end of the ratchet cover 35. The output end of the second electric push rod 38 extends between the inner walls of the ratchet cover 35, and the output end of the second electric push rod 38 is rotatably connected to the pawl 37.

[0061] In the present invention, the ratchet cover 35 is used to accommodate the ratchet 36 and the pawl 37. The ratchet 36 rotates synchronously with the second driven gear 32. The pawl 37 restricts the rotation of the second driven gear 32 through engagement with the ratchet cover 35. The second electric push rod 38 is used to push the pawl 37 to deflect. When the output end of the second electric push rod 38 extends to push the pawl 37 close to the ratchet 36, the pawl 37 engages with the ratchet 36 to restrict and lock the rotation of the second driven gear 32. When the output end of the second electric push rod 38 contracts to pull the pawl 37 away from the ratchet 36, the pawl 37 cancels the engagement with the ratchet 36, and then eliminates the locking of the rotation of the second driven gear 32. By using the engagement of the pawl 37 with the ratchet 36, the up and down angles of the grinding machine 26 are locked. Then, the rotating housing 8 is rotated so that the locked grinding machine 26 grinds the upper and lower edges of the curved hole of the housing 8 one by one.

[0062] A bracket 11 is fixedly connected to the side end of the mounting frame 10, and a camera 12 is fixedly connected to the bottom of the bracket 11.

[0063] In the present invention, the bracket 11 is used to support and fix the camera 12. The camera 12 is used to collect real-time pictures of the grinding of the curved hole of the housing 8 by the grinding machine 26. By using the collected real-time image data, data support is provided for the three-dimensional movement of the grinding machine 26.

[0064] A gyroscope 27 is fixedly connected to the side end of the deflection rod 23.

[0065] In the present invention, the gyroscope 27 is used to deflect synchronously with the deflection rod 23, and is used to collect the deflection angle of the grinding machine 26 in real time, providing data support for the up and down deflection of the grinding machine 26.

[0066] A method for using a differential housing grinding device includes the following steps:

[0067] S1. Clamping the workpiece:

[0068] Place the housing 8 between the conical pressing block 14 and the rubber turntable 7, such that the housing 8 is located between the two arc-shaped limiting plates 6. Power on and start the first electric push rod 13. The output end of the first electric push rod 13 presses down, causing the conical pressing block 14 to insert into the top of the housing 8. The conical pressing block 14 clamps the housing 8 by approaching the rubber turntable 7, thereby realizing the clamping of the housing 8 as the workpiece.

[0069] S2. Parameter acquisition:

[0070] After clamping the workpiece, power on and start the camera 12 and the gyroscope 27. The camera 12 acquires the position image of the housing 8 and the grinding machine 26, calculates the distance parameter between the grinding machine 26 and the housing 8 through the image, and the gyroscope 27 automatically acquires the horizontal angle between the deflection rod 23 and the grinding machine 26, thereby realizing the acquisition of the three-dimensional coordinate data parameters between the grinding machine 26 and the housing 8.

[0071] S3. Automatic feeding:

[0072] After parameter acquisition, the output end of the second electric push rod 38 pushes the pawl 37 to engage and lock with the ratchet 36, and the gyroscope 27 detects that the horizontal angle of the grinding machine 26 is zero. Power on and start the pushing motor 19. The output end of the pushing motor 19 drives the lead screw 18 to rotate. The lead screw 18 pushes the slider 20 to reciprocate within the rail frame 15 through the sliding fit with the slider 20. The slider 20 drives the moving plate 21 to move horizontally. The moving plate 21 drives the support frame 22, the drive assembly, the link assembly, and the grinding machine 26 to move horizontally, inserts the grinding machine 26 into the curved hole of the housing 8, and then powers off and stops the pushing motor 19, thereby realizing the automatic feeding of the grinding machine 26.

[0073] S4. Ring grinding:

[0074] After automatic feeding, the output end of the second electric push rod 38 contracts to pull the ratchet pawl 37 away from the ratchet wheel 36, releasing the engagement and locking between the ratchet pawl 37 and the ratchet wheel 36. The deflection motor 34 is powered on and started, and the output end of the deflection motor 34 drives the second driving gear 33 to rotate. The second driving gear 33 drives the second driven gear 32 to rotate through meshing with the second driven gear 32. The second driven gear 32 drives the driving rod 30 and the ratchet wheel 36 to deflect, so that the ratchet wheel 36 deflects synchronously with the driving rod 30. The driving rod 30 pulls the pull rod 29, and the pull rod 29 pulls the driven rod 28, so that the driven rod 28 deflects synchronously with the driving rod 30. The driven rod 28 drives the deflection rod 23 to deflect, so that the deflection rod 23 drives the grinding machine 26 to deflect up and down. At the same time, the stepping motor 5 is powered on and started, and the output end of the stepping motor 5 drives the first driving gear 3 to rotate. The first driving gear 3 drives the first driven gear 4 to rotate through meshing with the first driven gear 4. The first driven gear 4 drives the rubber turntable 7 to rotate, and the rubber turntable 7 drives the housing 8 to deflect axially. Then, the grinding machine 26 moves annularly in the curved hole of the housing 8. At the same time, the camera 12 is used to detect in real time whether the grinding machine 26 fits the edge of the curved hole, and is used to adjust the three-dimensional coordinate parameters, so that the grinding machine 26 performs annular cutting on the edge of the curved circular hole;

[0075] S4. Deburring:

[0076] During the annular grinding process, the up-and-down deflection angle of the grinding machine 26 and the vertical axial deflection of the housing 8 make the grinding head of the grinding machine 26 fit the edge of the curved circular hole. At the same time, the camera 12 performs real-time three-dimensional data detection on the grinding machine 26, and then the grinding head has the ability of automatic adjustment, realizing the deburring of the edge of the curved circular hole of the housing 8;

[0077] S5. Quick blanking:

[0078] After annular grinding, the grinding machine 26 moves to the middle of the curved hole, and the grinding machine 26 is at a horizontal angle of zero degrees. At this time, the pushing motor 19 is powered on and started, and the pushing motor 19 drives the lead screw 18 to rotate. The lead screw 18 pulls the moving plate 21 to reset through the sliding fit with the slider 20. Then, the support frame 22, the driving component, the connecting rod component, and the limiting component, and the grinding machine 26 are horizontally reset. After the camera 12 detects that the grinding machine 26 is withdrawn from the housing 8, the output end of the first electric push rod 13 contracts to lift the tapered pressing block 14, and the tapered pressing block 14 is withdrawn from the top of the housing 8, which is convenient to take out the housing 8, realizing the quick blanking of the housing 8.

[0079] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
