A fixing fixture is provided above the slide rail 16. The table tennis racket plate is fixed on the fixing fixture. The table tennis racket plate on the fixing fixture moves toward the grinding head 4 via the slide rail 16, so that the grinding head can evenly polish the edge of the table tennis racket plate.
[0019] The workbench 1 is provided with a door 12 on the side, and a baffle 2 is provided on the upper end surface of the workbench 1 to prevent wood chips generated by grinding from spreading outward. Dust suction holes 3 are distributed on the upper end surface of the workbench 1, and wood chips enter the vacuum cleaner 13 below through the dust suction holes 3.
[0020] A vacuum cleaner 13 is provided in the workbench 1 , and a dust hood 14 is provided on the air inlet pipe of the vacuum cleaner 13 . The opening of the dust hood 14 is connected to the top surface of the workbench 1 , and the dust hood 14 is communicated with each dust suction hole 3 . Wood chips enter the vacuum cleaner 13 through the dust hood 14 to prevent wood chips from falling into the workbench 1 .
[0021] A fixing block 17 is provided above the slide rail 16 , and the fixing block 17 is rotatably connected to the slide rail 16 . Thread holes are distributed on the upper end surface of the fixing block 17 , and a fixing fixture is installed on the fixing block 17 .
[0022] The fixing fixture includes a lower fixing plate 5, a connecting block 7, an upper fixing plate 6, a pressing plate 9, a connecting rod 10 and a sleeve 11. A connecting block 7 is provided at the end of the lower fixing plate 5. The connecting block 7 is provided with a longitudinally arranged limiting groove 8 and a wire hole. An upper fixing plate 6 is provided on the connecting block 7. The upper fixing plate 6 is arranged parallel to the lower fixing plate 5. The table tennis racket plate is fixed between the upper fixing plate 6 and the lower fixing plate 5. The edge of the table tennis racket plate extends out of the edge of the upper fixing plate 6 and the lower fixing plate 5. A slider 19 is provided at the end of the upper fixing plate 6. The slider 19 is arranged in cooperation with the limiting groove 8. The pressing plate 9 abuts against the upper end surface of the upper fixing plate 6. A connecting rod 10 is provided above the pressing plate 9. A longitudinally arranged sleeve 11 is provided at the end of the connecting rod 10. The sleeve 11 is connected to the connecting block 7 by bolts. The downward pressure of the pressing plate 9 on the upper fixing plate 6 is adjusted by the bolt on the sleeve 11.
[0023] The lower end surface of the lower fixing plate 5 is provided with a fixing hole 18, and the upper end of the fixing block 17 is arranged in the fixing hole 18. The fixing hole 18 is provided with countersunk holes that are matched with the thread holes of the fixing block 17. The lower fixing plate 5 and the fixing block 17 are fixed and installed by bolts.
[0024] The table tennis racket production and polishing device described in the embodiment is as follows: when in use, the corresponding lower fixing plate 5 is installed on the fixing block 17 according to the shape of the table tennis racket, and the two are fixed with bolts. The cut table tennis racket sheet is installed on the lower fixing plate 5, and the upper fixing plate 6 is pressed on the table tennis racket sheet. The slider 19 is installed in the limit groove 8, and then the pressing plate 9 is pressed above the upper fixing plate 6, and the sleeve 11 is fixed to the connecting block 7 with bolts. The downward pressure of the pressing plate 9 on the upper fixing plate 6 is adjusted by the bolts on the sleeve 11. After the fixing is completed, The grinding head 4 pushes the fixing fixture in the direction of the grinding head 4 to grind the edge of the table tennis racket plate. The fixing fixture is rotated during the grinding process so that the grinding head 4 can grind the periphery of the plate completely and evenly. The upper fixing plate 6 and the lower fixing plate 5 prevent the grinding head 4 from grinding too deeply. During the grinding process, the baffle 2 prevents the wood chips generated by the grinding from spreading outward. The vacuum cleaner 13 exhausts outward, so that the dust suction hole 3 generates negative pressure. The wood chips enter the dust collection cover 14 through the dust collection hole 3 and enter the vacuum cleaner 13 through the dust collection cover 14, preventing the wood chips from falling into the workbench 1.
