Description

Technical Field

[0001] The utility model relates to the technical field of grinding equipment, in particular to a high-precision grinding device for aluminum materials. Background Art

[0002] After aluminum plates, aluminum strips and other aluminum materials have been cut, burrs and barbs will inevitably appear on the cut sides, which will not only easily cause scratches during transportation, but also affect product quality. Therefore, deburring is an inevitable process.

[0003] In recent years, with the increasing quality requirements of aluminum alloy workpieces, people have more stringent requirements for deburring. The traditional method of filing with a file is inefficient and the quality of deburring is affected by subjective consciousness, that is, the quality is inconsistent. The manual method can no longer meet the needs of mass production. Therefore, many companies will use machining methods to improve efficiency and product deburring quality stability, such as die punching, grinding, freezing, and hot blasting. Among them, die punching, freezing, and hot blasting have higher process requirements and equipment requirements, and higher production costs. Grinding is usually performed by roller or sandblasting. Although the cost is low, there is a problem that the removal is not very clean.

[0004] To this end, the utility model provides a high-precision aluminum material grinding device to solve the problem of incomplete grinding and deburring. Utility Model Content

[0027] The following will be combined with the attached embodiment of the utility model Figure 1-6 , the technical solutions in the embodiments of the utility model are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0028] Embodiment 1, in order to solve the problems existing in the prior art, this embodiment provides a high-precision aluminum grinding device, including a frame 1, a receiving hopper 2 is provided at the lower end of the frame 1, for collecting burrs and slags under grinding; two drive shafts 3 are vertically symmetrically rotatably installed on the frame 1, and a plurality of drive wheels 4 are arranged along the two drive shafts 3, and the plurality of drive wheels 4 diverge from the center of the drive shaft 3 to both ends and are close to the center of the drive shaft 3, and a plurality of rollers 5 are rotatably installed on both sides of the two drive shafts 3 on the frame 1, and the plurality of drive wheels 4 are located at the length of the rollers 5. Within the range, two limit plates 6 are symmetrically and slidingly installed on the frame 1 along the axial direction of the driving shaft 3, and through holes are provided on the two limit plates 6. Multiple groups of grinding mechanisms are arranged at intervals in the through holes, and each group of grinding mechanisms includes two symmetrical grinding discs 7. The grinding discs 7 are rotatably installed on the limit plates 6. A turntable 8 that rotates coaxially with one grinding disc 7 is provided on the frame 1. A rocker 9 is rotatably installed on the end surface of the turntable 8. A grinding stone 10 is rotatably connected to the end of the rocker 9. A notch is provided on the side wall of the grinding stone 10. The turntable 8, the rocker 9, and the grinding stone 10 form a crank slider mechanism.

[0029] The two drive shafts 3 are driven by a first drive device to rotate relative to each other. The first drive device includes two gears 11 rotatably mounted on the side walls of the frame 1. The two gears 11 are meshed and respectively connected to a drive shaft 3 through a belt transmission. One gear 11 is driven by a first motor fixed to the frame 1. The first motor rotates to drive a gear 11 to rotate. The two gears 11 are meshed and rotate synchronously and in opposite directions. The two drive shafts 3 are driven to rotate in opposite directions through the belt transmission. After the aluminum material is placed on the frame 1, the driving wheels 4 on the upper and lower drive shafts 3 respectively abut against the upper and lower end surfaces of the aluminum material. As the drive shaft 3 rotates, the driving wheels 4 rotate synchronously to drive the aluminum material to roll on the roller 5, thereby completing the aluminum material conveying operation.

[0030] The two limit plates 6 are driven by a second driving device to move toward or relative to each other. The second driving device includes a double-headed screw 14 rotatably mounted on the frame 1. The double-headed screw 14 is driven by a second motor fixed to the frame 1. Both ends of the double-headed screw 14 are respectively provided with a section of thread with opposite rotation direction, and each section of thread is threadedly connected to a limit plate 6. The second motor drives the double-headed screw 14 to rotate, thereby driving the two limit plates 6 to move relative to or away from each other, so that the distance between the limit plates 6 can be adjusted according to the width of the aluminum material, thereby improving the practicality, applicability and flexibility of the device; the two limit plates 6 can always be tightly clamped on both sides of the aluminum material, that is, to guide the transportation of the aluminum material, and to ensure that the grinding mechanism can maintain contact with the aluminum material.

[0031] The two grinding discs 7 are driven by a third driving device to rotate synchronously. The third driving device includes two sets of chain drives. Each set of chain drives includes multiple sprockets rotatably mounted on the limit plate 6. The three sprockets are connected by chains, and one of the sprockets in the two sets of chain drives rotates coaxially, and the remaining sprockets rotate coaxially with the grinding disc 7 on the same side, so that all the sprockets form a whole and rotate synchronously. One sprocket is driven by a third motor fixed to the frame 1. The third motor rotates and drives all the grinding discs 7 synchronously through chain transmission.

[0032] The specific implementation process of this embodiment is as follows:

[0033] When in use, the aluminum material is placed at one end of the frame 1, and the first driving device is used to make the aluminum material roll on the surface of the roller 5 and be continuously conveyed. During the conveying process of the aluminum material, the third driving device drives the grinding disc 7 to rotate rapidly, so as to grind the upper and lower ends of both sides of the aluminum material to remove burrs; at the same time, the turntable 8 rotates synchronously with the corresponding grinding disc 7. The rotation of the turntable 8 drives the grindstone 10 to slide back and forth continuously in the through hole through the rocker 9. The notch of the grindstone 10 is buckled on the side of the aluminum material, thereby forming an effect similar to that of a hand file. Such two-stage filing improves the grinding accuracy and effect, thereby improving the burr removal effect and minimizing the amount of burr residue.

[0034] Embodiment 2, since the device can be applied to aluminum materials of different widths, that is, the positions of the two limit plates 6 are adjustable, the length of the roller 5 can only be the narrowest aluminum model. In order to keep both sides of the aluminum material stable and level, that is, to maintain a good guiding and conveying state, it is necessary to set a lifting device on both sides of the aluminum material. Therefore, in this embodiment, a plurality of connecting shafts 12 are rotatably installed on both sides of the two driving shafts 3 on the frame 1, and the roller 5 is fixedly connected between the two corresponding connecting shafts 12 on the frame 1. The diameter of the connecting shaft 12 is smaller than the diameter of the roller 5. The two limit plates 6 are rotatably mounted with sleeves 13 corresponding to the rollers 5. The sleeves 13 cover the connecting shaft 12. The outer wall of the sleeve 13 is flush with the outer wall of the roller 5, and a gap is set between the inner wall and the outer wall of the connecting shaft 12, so that the outer wall of the sleeve 13 is flush with the outer wall of the roller 5 and does not contact the roller 5 and the connecting shaft 12, thereby reducing friction. When the two limit plates 6 clamp the aluminum material, the two sides of the aluminum material are placed on the sleeves 13, and the sleeves 13 provide support to maintain stable transportation.
