Moreover, the positioning accuracy is low. In addition, the traditional machining method requires the workpiece to be clamped and hoisted multiple times, which is cumbersome, time-consuming, and has low production efficiency.

[0022] Reference Figures 1 to 6As shown, an embodiment of this application discloses a diesel engine disc wheel indexing line processing device, comprising: a base 100, a mounting bracket 400, and a sliding part 500. A positioning part 110 is provided on the base 100 for mounting the disc wheel 200, and a first driving member 300 is provided on the base 100. The mounting bracket 400 is hinged to the base 100, and a circular guide rail 410 is bolted to the mounting bracket 400. The mounting bracket 400 has a first position and a second position. When the mounting bracket 400 is in the first position, the circular guide rail 410 is horizontal and is fitted onto the positioning part 110. The center of the circular guide rail 410 coincides with the projection of the center of the disc wheel 200 in the vertical direction. When the mounting bracket 400 is in the second position, both the mounting bracket 400 and the circular guide rail 410 are spaced above the positioning part 110. The first drive member 300 is used to drive the mounting bracket 400 to switch between the first and second positions, reducing the labor intensity of manual flipping by the operator. When the mounting bracket 400 is in the second position, the disc wheel 200 can be vertically hoisted to the positioning part 110 directly using a crane or other equipment, shortening the loading and unloading time and reducing the risk of the disc wheel 200 hitting the circular guide rail 410 during hoisting. The sliding part 500 is slidably connected to the circular guide rail 410 and can move in a circle along the circular guide rail 410. The sliding part 500 is connected to the second drive member 600, which is a linear guide rail. The second drive member 600 is connected to a carving knife 700. When the mounting bracket 400 is in the first position, the second drive member 600 can drive the carving knife 700 to process the disc wheel 200. The heavy-duty disc wheel 200 has significant inertia during startup and shutdown, making positioning difficult and potentially causing deviations in the engraving line position. In this embodiment, the heavier disc wheel 200 remains stationary during processing. Instead, the sliding part 500 drives the lighter second drive component 600 and the engraving cutter 700, ensuring a constant distance between the engraving cutter 700 and the center of the disc wheel 200. The radial error of the engraved graduation line depends only on the error of the circular guide rail 410 itself, thereby improving processing accuracy.

[0023] Reference Figures 1 to 6 As shown, in some embodiments, a positioning shaft 111 is provided at the upper end of the positioning part 110. The positioning part 110 and the positioning shaft 111 are welded together. The upper end of the positioning shaft 111 is chamfered, which reduces the difficulty for the operator to adjust the lifting device. A center hole 210 is provided on the disc wheel 200, and the positioning shaft 111 passes through the center hole 210. Because the position of the circular guide rail 410 can be repeatedly positioned, only the disc wheel 200 needs to be precisely positioned. The positioning shaft 111 serves to position the disc wheel 200 in the horizontal plane. The weight of the disc wheel 200 is borne by the upper end surface of the positioning part 110, and the positioning shaft 111 is only responsible for horizontal limiting.

[0024] Reference Figures 1 to 6As shown, in some embodiments, the mounting bracket 400 is welded with a circular ring portion 420, which is coaxially arranged with a circular guide rail 410. The circular guide rail 410 is bolted to the circular ring portion 420, which improves the torsional stiffness of the circular guide rail 410. The circular guide rail 410 is a consumable part and is bolted together. When the circular guide rail 410 wears and causes the roundness to exceed the tolerance, the accuracy can be restored simply by replacing the circular guide rail 410. The circular ring portion 420 allows the positioning portion 110 to pass through, and the outer peripheral wall of the circular ring portion 420 is provided with a scale. The inner diameter of the circular ring portion 420 is larger than the outer diameter of the positioning portion 110. When the mounting bracket 400 is flipped to the first position, the positioning portion 110 and the disc wheel 200 pass through the center of the circular ring portion 420. The operator can directly read the current angle on the scale on the outer peripheral wall of the circular ring portion 420 using a pointer or vernier provided on the sliding portion 500.

[0025] Reference Figures 1 to 6 As shown, in some embodiments, a third driving member 800 is bolted to the sliding part 500, and the third driving member 800 is used to drive the sliding part 500 to move along the circular guide rail 410. Integrating the third driving member 800 onto the sliding part 500 enables automatic driving of the sliding part 500 to move, reducing errors caused by manual intervention.

[0026] Reference Figures 1 to 6 As shown, in some embodiments, the third drive component 800 is an electric motor, which can be a servo motor or a stepper motor. The output shaft of the third drive component 800 is connected to a rubber wheel 810, which abuts against the outer wall of the annular portion 420. The friction between the rubber wheel 810 and the stationary outer wall of the annular portion 420 drives the second drive component 600 to move in a circular motion along the circular guide rail 410. The rubber wheel 810 and the outer wall of the annular portion 420 are frictionally coupled, with no mechanical meshing clearance, which improves positioning repeatability. If an accident occurs during processing and the rubber wheel 810 slips, it can prevent the motor from stalling and overloading.

[0027] Reference Figures 1 to 6 As shown, in some embodiments, two sliding portions 500 are symmetrically arranged, and the two sliding portions 500 are respectively connected to both ends of the second driving member 600. The two sliding portions 500 are also connected by a support ring 501. The support ring 501 is located below the annular portion 420. If there is only one sliding portion 500 on one side, the second driving member 600 forms a cantilever structure, which is prone to deformation. By providing sliding portions 500 at both ends of the second driving member 600, the structural strength and processing accuracy are effectively improved.

[0028] Reference Figures 1 to 6As shown, in some embodiments, the second drive unit 600 may be a rodless cylinder or a linear module, or other mechanism capable of linear drive. The movable end of the second drive unit 600 is bolted to an adapter 610, and the carving knife 700 is detachably mounted on the adapter 610. When replacing the carving knife 700, only the connecting bolts of the adapter 610 need to be unscrewed, reducing the knife replacement time.

[0029] Reference Figures 1 to 6 As shown, in some embodiments, the adapter 610 has a vertically extending strip-shaped hole 611, and the carving knife 700 has multiple bolt holes 710. The number of bolt holes 710 is at least two to prevent the carving knife 700 from rotating. The number of bolt holes 710 is determined by the size of the carving knife 700. The adjusting bolt 720 passes through the strip-shaped hole 611 and the bolt holes 710 and can move up and down within the strip-shaped hole 611. When the thickness of the rotating wheel 200 changes or the carving knife 700 wears, simply loosening the adjusting bolt 720 allows the carving knife 700 to be moved continuously and arbitrarily within the range of the strip-shaped hole 611, making adjustment convenient.

[0030] Reference Figures 1 to 6 As shown, in some embodiments, a bearing bracket 101 is connected to the base 100, and a rotating shaft 401 is provided on the side of the mounting bracket 400, through which the rotating shaft 401 passes. The bearing bracket 101 is bolted to the base 100, and the rotating shaft 401 is welded to the mounting bracket 400. Two bearing brackets 101 are symmetrically arranged.

[0031] Reference Figures 1 to 6 As shown, in some embodiments, a rocker arm 402 is connected to the rotating shaft 401. The rocker arm 402 is perpendicular to the rotating shaft 401. The first driving member 300 is a hydraulic cylinder. The first driving member 300 drives the mounting bracket 400 to rotate via the rocker arm 402. The fixed end of the first driving member 300 is hinged to the base 100, and the telescopic end of the first driving member 300 is hinged to the rocker arm 402. During the swinging of the rocker arm 402, the centerline of the hydraulic cylinder will deflect at an angle. The hinge points at both ends of the hydraulic cylinder can rotate freely to adapt to this change, ensuring that the piston rod of the hydraulic cylinder only bears axial pushing and pulling forces.

[0032] Operating steps: Extend the telescopic end of the first drive component 300. Drive the mounting bracket 400 to the second position via the rocker arm 402, hoisting the disc wheel 200 to be processed onto the upper surface of the positioning part 110, so that the positioning shaft 111 passes through the center hole 210 of the disc wheel 200. Retract the telescopic end of the first drive component 300, and rotate the mounting bracket 400 to the horizontal first position. According to the required depth of the engraving, loosen the adjusting bolt 720 passing through the strip hole 611 on the adapter 610, move the engraving blade 700 up and down to the appropriate height, and then lock it. The third drive component 800 drives the sliding part 500 to move in a circular motion along the circular guide rail 410. The two symmetrically arranged sliding parts 500 simultaneously drive the second drive component 600 and the engraving blade 700 to rotate around the center of the disc wheel 200 to the initial position. Start the second drive component 600 to push the adapter 610, causing the engraving blade 700 to feed towards the surface of the disc wheel 200, completing the engraving. The first indexing line is engraved on the disc wheel 200. After completing one engraving line, the second drive unit 600 retracts, causing the engraving cutter 700 to detach from the workpiece surface. The third drive unit 800 then activates, precisely moving the sliding part 500 to the next angular position. The second drive unit 600 then feeds the engraving cutter 700 again to process the next engraving line. This cycle continues until all indexing lines are processed. After processing is complete, the first drive unit 300 extends, and via the rocker arm 402, it drives the mounting bracket 400 to rotate to the second position, freeing up space above the positioning part 110 for easy lifting and removal of the processed disc wheel 200.

[0033] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
