Description

Technical Field

[0001] This utility model relates to the field of wheel rim processing technology, specifically to a wheel rim weld grinding machine. Background Technology

[0002] One type of wheel rim is a cylindrical body made up of three cylindrical parts of different lengths welded together. After the welding is completed, there will inevitably be two uneven annular welds. In order to prevent the uneven annular welds from affecting assembly, use and aesthetics, the two welds need to be ground.

[0003] In the existing technology, the grinding of the weld seam in the wheel rim is usually done by placing the welded wheel rim on a rotating support and then grinding the weld seam manually. However, when the grinding machine grinds the wheel rim placed on the rotating support, the wheel rim is prone to displacement as the rotating support rotates, which makes it impossible to grind the weld seam accurately. The processing stability is relatively poor and the processing accuracy is relatively low.

[0004] In view of this, the applicant has conducted in-depth research on the above-mentioned issues, which led to this case. Utility Model Content

The base 10 is provided with a support component for supporting and fixing the wheel rim and a grinding component for grinding the wheel rim weld. The support component and the grinding component are arranged sequentially along the length direction of the base.

[0036] A first X-axis slide rail 20 is provided on the base 10 along its length. The base 10 is a rectangular plate. It should be noted that the length direction of the base 10 is the length direction of each component in a rim weld grinding machine, and the width direction of the base 10 is the width direction of each component in a rim weld grinding machine. The support assembly includes a horizontally arranged base plate 21, which is slidably connected to the first X-axis slide rail 20. A plurality of vertically arranged columns 23 are provided on the side of the base plate 21 away from the base 10.

The outer periphery of each column 23 is respectively provided with a corresponding column. A limiting ring 26 is coaxially arranged. Multiple elastic elements 27 are provided between the pressure plate 25 and the base plate 21. In this embodiment, each elastic element 27 is a spring. Each elastic element 27 is paired and fitted onto each column 23. One end of each elastic element 27 abuts against the side of the pressure plate 25 facing the base plate 21, and the other end abuts against the upper side of the corresponding limiting ring 26. Support rollers 28 are provided on the pressure plate 25 via supports. There are two support rollers 28, arranged side-by-side along the width direction of the pressure plate 25. The projection of the fixing seat 24 in the horizontal direction is located between the two support rollers 28. The axis of each support roller 28 is parallel to the length of the rectangular base 10. A positioning seat 29 is fixedly installed on the fixed base 24. The upper end of each supporting roller 28 is horizontally higher than the upper surface of the positioning seat 29. The positioning seat 29 has a positioning groove 30 arranged along the length direction of the base 10, and the positioning groove 30 passes through both ends of the positioning seat 29 along the length direction. The base 10 is also provided with a first driving mechanism for driving the base plate 21 to move along the first X-axis slide rail 20. The first driving mechanism is electrically connected to the controller. In this embodiment, the first driving mechanism is a second cylinder 46.

The cylinder body of the second cylinder 46 is fixedly installed on the base 10. The piston rod of the second cylinder 46 is connected to the controller. The base plate 21 is fixedly connected, and a clamping assembly for clamping the wheel rim is fixedly connected to the base plate 21 via a bracket. The clamping assembly is located directly above the positioning seat 29. In use, the wheel rim to be processed is placed on the positioning seat 29. It should be noted that the weld of the wheel rim includes the inner weld on the inner circumference of the wheel rim and the outer weld on the outer circumference of the wheel rim. The wheel rim to be processed is supported by the support roller 28, so that the outer weld of the wheel rim is engaged in the positioning groove 30. By using the positioning seat 29 with the positioning groove 30 and the clamping assembly, the wheel rim is placed on the positioning seat 29 during grinding, which plays a role in positioning and support. The clamping assembly is used to achieve positioning and clamping, resulting in relatively good processing stability and relatively high processing accuracy.

[0037] The grinding assembly includes multiple guide posts 31 arranged vertically on the base 10. Each guide post 31 is slidably connected to the same lifting plate 32.

The second drive mechanism and the third drive mechanism are electrically connected to the controller. In use, the controller controls the lead screw jack to start, the lead screw jack starts and drives the lead screw to rotate, the lead screw rotates and drives the lifting plate 32 to move. The controller controls the servo motor 40 to start, the servo motor 40 drives the mounting plate 35 to move. The controller controls the servo motor 40 and the lead screw jack to achieve linkage, thereby accurately grinding the inner weld of the rim.

[0039] A grinding wheel motor 26 is fixedly mounted on the mounting plate 35. The output end of the grinding wheel motor 36 is fixedly connected to a first rotating shaft 38 arranged horizontally and facing the support assembly via a coupling 37. A grinding wheel 39 is fixedly connected to the end of the first rotating shaft 38 facing the support assembly. The controller controls the grinding wheel motor 26 to start, and the grinding wheel motor 26 drives the first rotating shaft 38 to rotate. The rotation of the first rotating shaft 38 drives the grinding wheel 39 to rotate, thereby realizing the grinding of the inner weld seam of the wheel rim.

[0040] A protective cover (not shown in the figure) is provided on the base 10. A partition 41 arranged along the width direction of the base 10 is fixedly installed on the base 10. The partition 41 separates the support assembly and the grinding assembly. In this embodiment, the first X-direction slide rail 20 is located on one side of the partition 41, and the second X-direction slide rail 43 is located on the other side of the partition 41. The partition 41 is provided with a long strip hole 42 for the first rotating shaft 38 to pass through and is arranged vertically. By providing the partition 41, the welding slag removed by grinding can be prevented from contacting the screw jack.

[0041] A photoelectric measuring head is fixedly installed on the partition plate 41. The photoelectric measuring head is electrically connected to the controller. In this embodiment, the photoelectric measuring head is used to measure the distance between the first rotating shaft 38 and the base 10. When the distance between the first rotating shaft 38 and the base 10 is less than a predetermined distance, a new grinding wheel 39 is replaced.

[0042] The clamping assembly includes a first cylinder 44, with its piston rod facing downwards. The cylinder body of the first cylinder 44 is fixedly connected to a bracket, and a pressure block 45 is fixedly connected to the piston rod of the first cylinder 44. The pressure block 45 is located directly above the positioning seat 29. The first cylinder 44 is electrically connected to a controller. In use, the controller controls the first cylinder 44 to extend, which in turn moves the pressure block 45 downwards, clamping and fixing the wheel rim onto the positioning seat 29. The wheel rim is clamped and fixed through the cooperation of the first cylinder 44, the pressure block 45, and the positioning seat 29, resulting in a relatively good fixing effect.

[0043] In use, the controller controls the second cylinder 46 to drive the base plate 21 to move away from the partition 41 to its limit position, placing the rim to be processed onto the positioning seat 29. The support roller 28 rotates the rim to be processed, causing the outer weld seam of the rim to be engaged into the positioning groove 30. The controller controls the first cylinder 44 to extend, which drives the pressure block 45 to move downward, pressing and fixing the rim onto the positioning seat 29. The controller controls the second cylinder 46 to drive the base plate 21 to move closer to the partition 41 to its limit position. The controller controls the grinding wheel motor 26 to start, which drives the first rotating shaft 38 to rotate. The rotation of the first rotating shaft 38 drives the grinding wheel 39 to rotate, thereby grinding the inner weld seam of the rim. After grinding, the controller controls the grinding wheel motor 26 to stop, and then controls the second cylinder 46 to drive the base plate 21 to move away from the partition 41 to its limit position. Finally, the rim with the ground weld seam is removed.
