Description

Technical Field

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

[0002] A wheel rim, commonly known as a wheel hub, is a component on a wheel that mounts and supports the tire, forming the wheel together with the spokes. During the wheel rim manufacturing process, especially after welding and rolling processes, the finished rim inevitably has irregular protrusions such as burrs, flash, sharp edges, and burrs on its edges (including the top of the rim flange and the edge of the bead seat). These burrs and sharp edges may seem minor, but they can cause a series of serious problems, such as safety hazards, operator injury, poor sealing, and performance degradation.

[0003] Patent CN222430265U discloses a workpiece grinding device. During operation, the workpiece to be ground is placed on the grinding platform, and the position of the grinding section is adjusted via an adjustment unit, allowing the grinding section to be close to the workpiece for grinding or moved away after grinding. This device can only grind the outer edge of the rim profile (steel ring). After the rim is formed, its ends have more complex shapes and require more sophisticated grinding, which this device cannot meet. Currently, the removal of burrs from the rim edges mostly relies on manual grinding, which is inefficient and produces inconsistent quality. Utility Model Content

[0004] This utility model addresses the aforementioned shortcomings of existing technologies by providing a wheel rim edge burr grinding machine that integrates feeding, positioning, internal and external grinding, and unloading processes. It completely changes the problems of low efficiency and poor quality of manual grinding, realizes automated and highly efficient continuous production, avoids repeated positioning errors and time waste caused by step-by-step processing, and greatly improves grinding efficiency. To achieve the above objectives, this utility model provides the following technical solution: A wheel rim edge burr grinding machine includes a base, with a first and second support rollers for supporting the wheel rim at the upper end of the base. A frame is connected to the upper end of the base, and a first grinding mechanism is fixed on the frame. The first grinding mechanism is adjustable in both front-to-back and left-to-right positions. The first grinding mechanism includes a third motor, with a wire wheel on the output shaft of the third motor. A top plate is provided at the upper end of the frame, and a pressing mechanism is provided on the top plate. The pressing mechanism includes a second cylinder fixed to the top plate, with a pressure plate connected to the piston rod of the second cylinder. A pressure roller for pressing the wheel rim is connected below the pressure plate. Second grinding mechanisms are provided at both ends of the pressure plate, each including a second motor, with a grinding head on the output shaft of the second motor.

[0005] Preferably, one end of the first idler roller is connected to a first motor fixed to the machine base, the second idler roller is liftable, and both the first and second idler rollers are fitted with positioning rings on their outer sides. The machine base is provided with a positioning cylinder, and the piston rod of the positioning cylinder is provided with a push block, which can push the rim so that one end of it rests against the positioning ring. Preferably, the two ends of the second idler roller are connected to swing frames, the swing frames are connected to the machine base via rotating shafts, and the end of the swing frame away from the second idler roller is connected to the machine base with a first cylinder. Preferably, a feed plate is provided on one side of the first idler roller, and a discharge plate is provided on one side of the second idler roller. Guardrails are provided on both sides above the feed plate and the discharge plate. Preferably, both the feed plate and the discharge plate are inclined, and the inclination direction is the same.

[0006] Preferably, the first grinding mechanism further includes an upper moving seat, a lower moving seat, and a fixed seat. The fixed seat is fixed to the frame. The bottom of the lower moving seat is connected to the fixed seat via a magnetically coupled rodless cylinder. The upper end of the lower moving seat is provided with a guide rail. The bottom of the upper moving seat cooperates with the guide rail via a slider. The lower moving seat is provided with a third cylinder for driving the upper moving seat. The third motor is fixed to the upper end of the upper moving seat.

[0007] Preferably, a floating plate and a support frame for fixing the pressure roller are provided below the pressure plate. The lower end of the floating plate is connected to the second motor through a tilting cylinder. Both ends of the floating plate and the support frame are provided with guide columns that penetrate the pressure plate. The pressure plate, the floating plate, and the support frame are connected by springs. A guide cylinder is provided on the top plate. A guide rod that penetrates the pressure plate and the guide cylinder is connected to the upper end of the floating plate. A limit rod is connected to the upper end of the guide rod.

[0008] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model integrates the processes of feeding, positioning, internal and external grinding, and unloading, completely changing the problems of low efficiency and poor quality of manual grinding, and realizing automated and highly efficient continuous production; the first roller, the second roller, and the pressure roller together form a stable "three-point support", which effectively prevents the rim from shifting or vibrating during the grinding process and ensures the stability of the grinding trajectory; the internal and external grinding mechanisms work simultaneously during the rotation of the rim, completing the cleaning of all edge burrs in one go, avoiding the repeated positioning errors and time waste caused by step processing, and greatly improving grinding efficiency.

[0009] 2. The pressing mechanism of this utility model uses a spring to connect the floating plate and the support frame, so that the pressing roller and the grinding head have a certain buffering and floating ability when they come into contact with the workpiece. This can better adapt to the small deformation or positional deviation of the workpiece, prevent rigid impact from damaging the workpiece or equipment, and improve the stability of the process and the service life of the equipment.

[0010] 3. The relatively soft brass wire wheel is flexible enough to adapt well to the contour of the inner circle of the rim, effectively cleaning without damaging the workpiece substrate; the hard diamond pit wheel grinding head can efficiently and accurately remove burrs with more complex shapes on the outer edge of the rim.

[0011] 4. The inclined feed plate and discharge plate, combined with the lifting function of the second idler roller, allow the rim to automatically roll into and out of the work station under the action of gravity. The loading and unloading time is extremely short, which effectively reduces the idle waiting time of the equipment and improves the overall production efficiency. Attached Figure Description

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] like Figure 1As shown, a wheel rim edge burr grinding machine includes a base 6. The upper end of the base 6 is provided with a first roller 608 and a second roller 610 supporting the wheel rim. The upper end of the base 6 is connected to a frame 601. A first grinding mechanism 2 with opposite positions is fixed on the frame 601. The first grinding mechanism 2 can be adjusted in both front-to-back and left-to-right positions. The first grinding mechanism 2 includes a third motor 202. The output shaft of the third motor 202 is provided with a brass wire wheel. The relatively soft brass wire wheel has the flexibility to adapt well to the contour of the inner circle of the wheel rim, effectively cleaning without damaging the workpiece substrate. The upper end of the frame 601 is provided with a top plate 602, and the top plate 602 is provided with a pressing mechanism 1. The pressing mechanism 1 includes a second cylinder 102 fixed to the top plate 602. The piston rod of the second cylinder 102 is connected to a pressure plate 104. The pressure plate 104 is connected to a pressure roller 109 that presses down on the rim. The two ends of the pressure plate 104 are provided with a second grinding mechanism 4, which is located at both ends of the rim. The second grinding mechanism 4 includes a second motor 402. The output shaft of the second motor 402 is provided with a diamond pit wheel grinding head 403, which can grind the burrs on the outer circle of the rim. The diamond pit wheel grinding head 403, which is made of hard material, can efficiently and accurately remove burrs with more complex shapes on the outer edge of the rim.

[0015] The first idler roller 608, the second idler roller 610, and the pressure roller 109 together form a stable "three-point support," effectively preventing the rim from shifting or vibrating during grinding and ensuring the stability of the grinding trajectory. The inner and outer grinding mechanisms work simultaneously during the rim's rotation, completing the removal of all edge burrs in one go. This avoids the repetitive positioning errors and time wastage caused by step-by-step processing, significantly improving grinding efficiency.

[0016] One end of the first idler roller 608 is connected to a first motor 607 fixed to the machine base 6. The first motor 607 drives the first idler roller 608 to rotate, which in turn drives the rim to rotate. The second idler roller 610 can be raised and lowered. Positioning rings 609 are fitted on the outer sides of both the first idler roller 608 and the second idler roller 610. A positioning cylinder 5 is provided on the machine base 6. Figure 2 As shown, the piston rod of the positioning cylinder 5 is provided with a push block 501, which can push the rim so that one end of it rests against the positioning ring 609 to achieve the positioning of the rim. The two ends of the second idler roller 610 are connected to the swing frame 3. The swing frame 3 is connected to the machine base 6 through the rotating shaft. The end of the swing frame 3 away from the second idler roller 610 is connected to the machine base 6 by the first cylinder 611. The first cylinder 611 can drive the swing frame 3 to rotate, thereby realizing the lifting and lowering of the second idler roller 610. like Figure 3As shown, a feed plate 604 is provided on one side of the first idler roller 608, and a discharge plate 605 is provided on one side of the second idler roller 610. Guardrails 603 are provided on both sides above the feed plate 604 and the discharge plate 605. Both the feed plate 604 and the discharge plate 605 are inclined in the same direction. During loading, the second idler roller 610 rises, and the rim rolls along the feed plate 604 between the first idler roller 608 and the second idler roller 610. After grinding, the second idler roller descends, and the rim rolls out along the discharge plate 605. The inclined feed plate 604 and discharge plate 605, combined with the lifting function of the second idler roller 610, allow the rim to automatically roll into and out of the workstation under gravity, resulting in extremely short loading and unloading times, effectively reducing idle waiting time and improving overall production efficiency. like Figure 5 As shown, the first grinding mechanism 2 also includes an upper movable seat 203, a lower movable seat 209, and a fixed seat 208. The fixed seat 208 is fixed to the frame 601. The bottom of the lower movable seat 209 is connected to the fixed seat 208 through a magnetically coupled rodless cylinder 207, which can realize the left and right adjustment of the position of the third motor 202. The upper end of the lower movable seat 209 is provided with a guide rail 206. The bottom of the upper movable seat 203 cooperates with the guide rail 206 through a slider 205. The lower movable seat 209 is provided with a third cylinder 204 that drives the upper movable seat 203. The third motor 202 is fixed to the upper end of the upper movable seat 203, which can realize the front and back adjustment of the position of the third motor 202, realize the adjustment of the distance between the two first grinding mechanisms 2, and adapt to rims of different widths.

[0017] like Figure 4 As shown, two floating plates 107 and a support frame 108 for fixing the pressure roller 109 are provided below the pressure plate 104. The support frame 108 is located between the two floating plates 107. The lower end of the floating plate 107 is connected to the second motor 402 through a tilting cylinder 401. The angle of the grinding head 403 can be adjusted through the tilting cylinder 401. Both ends of the floating plate 107 and the support frame 108 are provided with guide posts 105 that penetrate the pressure plate 104. The pressure plate 104 is connected to the floating plate 107 and the support frame 108 through a spring 106. The spring 106 is sleeved on the outside of the guide post 105. A guide cylinder 606 is provided on the top plate 602. A guide rod 103 that penetrates the pressure plate 104 and the guide cylinder 606 is connected to the upper end of the floating plate 107. A limit rod 101 is connected to the upper end of the guide rod 103.

[0018] The pressing mechanism 1 uses a spring 106 to connect the floating plate 107 and the support frame 108, so that the pressure roller 109 and the grinding head 403 have a certain buffering and floating ability when they come into contact with the workpiece. This allows them to better adapt to the small deformation or positional deviation of the workpiece, prevent rigid impact from damaging the workpiece or equipment, and improve the stability of the process and the life of the equipment.

[0019] During processing, the wheel rim moves from the feed plate 604 to the upper end of the first idler roller 608 and the second idler roller 610. The positioning cylinder 5 is activated, and the push plate pushes the wheel rim so that one end of the wheel rim rests against the side of the positioning ring 609. Then the push plate resets, the second cylinder 102 is activated, and the pressure roller 109 presses against the upper end of the wheel rim. The first motor 607 is activated, driving the first idler roller 608 to rotate, thereby driving the wheel rim to rotate. The tilting cylinder 401 drives the grinding head 403 to rotate, so that the grinding head 403 grinds the burrs on the outer edge of the wheel rim. The third cylinder 204 is activated, so that the grinding wheel 201 grinds the burrs on the inner edge of the wheel rim. After grinding is completed, the first grinding mechanism 2 and the second grinding mechanism 4 are reset. After the pressure roller 109 is raised, the first cylinder 611 drives the swing frame 3 to rotate, so that the second idler roller 610 descends, and the wheel rim rolls out of the machine base 6 along the discharge plate 605.

[0020] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
