[0027] Reference Figures 1-4 According to an embodiment of the polyurethane buffer block edge grinding device of the present invention, it includes a processing table 11, a turntable 12 rotatably connected to the processing table 11, and a motor 13 for driving the turntable 12 to rotate is provided inside the processing table 11. It also includes a pressing component for locking the cylindrical polyurethane buffer block located on the turntable 12.

[0028] In this embodiment, the pressing assembly includes a support plate disposed on the processing table 11. A third cylinder 19 is disposed on the support plate. The lower end of the third piston rod in the third cylinder 19 is equipped with a mounting plate 20. A pressure plate 21 is rotatably connected to the lower side of the mounting plate 20. The pressure plate 21 is coaxial with the turntable 12 and is located on the upper side of the turntable 12.

[0029] Once the columnar polyurethane buffer block is placed on the turntable 12 and positioned correctly, the operator can control the pressure plate 21 to move downwards using the third cylinder 19 until the pressure plate 21 presses down on the polyurethane buffer block. After that, if the motor 13 is powered on, the pressure plate 21, the turntable 12, and the polyurethane buffer block will rotate, so that the grinding device on the processing table 11 can perform edge grinding on the polyurethane buffer block.

[0030] In this embodiment, the grinding device includes a first cylinder 14 disposed on the processing table 11. The first piston rod inside the first cylinder 14 is equipped with a mounting plate 15 at its end, and the first piston rod extends toward the axis of the turntable 12. A grinding plate 16 is installed inside the mounting plate 15. The operator can control the position of the grinding plate 16 through the first cylinder 14 so that it is attached to the polyurethane buffer block for edge grinding, or away from the polyurethane buffer block for positioning and fixing.

[0031] In a second embodiment of the polyurethane buffer block edge grinding device, in order to ensure that the columnar polyurethane buffer block is coaxial with the turntable 12 and the pressure plate 21 when it is clamped between the pressure plate 21 and the turntable 12, a pre-positioning device is also included. The support plate is supported by two vertical plates. The pre-positioning device includes two second cylinders 17 arranged opposite each other on the left and right sides. The two second cylinders 17 are respectively located on the sides of the two vertical plates that are far apart from each other. The end of the second piston rod in the second cylinder 17 is equipped with an arc plate 18. The two arc plates 18 are arranged opposite each other and are respectively located on the left and right sides of the turntable 12. The first piston rod is arranged obliquely.

[0032] When the worker places the polyurethane buffer block on the turntable 12, the arc-shaped plates 18 are controlled by the second cylinder 17 to move closer to each other and clamp and position the polyurethane buffer block so that it is coaxial with the turntable 12. Then the pressure plate 21 presses down and the two arc-shaped plates 18 move away from each other, thus completing the positioning of the polyurethane buffer block.

[0033] In a third embodiment of the polyurethane buffer block edge grinding device, to further simplify the workflow and reduce labor intensity, an ejection mechanism for automatic unloading is also included. The ejection mechanism includes an ejection groove 22 located on the upper side of the processing table 11. A top block 23 is slidably connected to the ejection groove 22, and the top block 23 is connected to the bottom surface of the ejection groove 22 by a spring. An electromagnet 24 for controlling the up and down position of the top block 23 is also provided in the ejection groove 22. Specifically, a magnet is embedded in the top block 23. When the electromagnet 24 is energized, it will repel the magnet to make the top block 23 eject upward. The ejection groove 22 is located on the eccentric side of the turntable 12 to push the polyurethane buffer block located thereon down to leave the turntable 12.

[0034] In order to facilitate the control of the path of the polyurethane buffer block pushed down by the top block 23, a sloping groove 25 is provided between the upper side and the front side of the processing table 11, and the sloping groove 25 is located on the front side of the turntable 12.

[0035] In order to make the polyurethane buffer block edge grinding device applicable to different specifications of cylindrical shapes, the grinding plate 16 is easy to replace. The specific installation method of the grinding plate 16 is as follows: the mounting plate 15 is provided with a mounting groove on the side away from the first piston rod, and a plug plate is provided on one side of the grinding plate 16 to be inserted into the mounting groove. The mounting plate 15 is also provided with bolts for locking the plug plate in the mounting groove.

[0036] The specific edge grinding process for polyurethane buffer blocks is as follows:

[0037] First, the worker places the polyurethane buffer block on the turntable 12. Then, by controlling the two arc-shaped plates 18 to move closer to each other, the arc surfaces within the two arc-shaped plates 18 will make the polyurethane buffer block coaxial with the turntable 12. After that, the pressure plate 21 sinks down to press the polyurethane buffer block, and then the two arc-shaped plates 18 move away from each other.

[0038] Then the motor 13 is powered on to drive the turntable 12 and the polyurethane buffer block thereon to rotate, and then the first cylinder 14 controls the grinding plate 16 and makes it stick to the polyurethane buffer block to perform edge grinding.

[0039] After the edge grinding is completed, the grinding plate 16 retracts. Then, the motor 13 controls the ejection slot 22 to be at the rearmost position. After that, the pressure plate 21 is raised, and the electromagnet 24 is energized. At this time, the top block 23 can be ejected upward. The polyurethane buffer block is pushed forward by the top block 23 and rolls down through the inclined groove 25. Then, the electromagnet 24 is de-energized, and the top block 23 will return to its original position under the action of the spring. At this time, the edge grinding of one polyurethane buffer block is completed.

[0040] The above-mentioned method for controlling the angle of the pop-out slot 22 by the motor 13 is existing technology and will not be described in detail here.

[0041] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
