[0023] Please see Figure 1-5This utility model provides a technical solution: a product positioning mold for a spindle deburring machine, including a mold base 1, a mold body 2, a cylinder 3, a pad 4, a fixing block 5, a wedge block 6, a pad block 7, and a tensioning protrusion 8. The mold body 2 is disposed at one end of the upper surface of the mold base 1, and has two through-holes 16 to cooperate with the spindle of the spindle deburring machine to deburr the holes of the workpiece. A receiving groove 17 is provided on the upper surface of the mold base 1, and the mold body 2 is disposed in the receiving groove 17. A limiting post 18 is provided on the upper surface of the mold base 1 away from the mold body 2. The receiving groove 17 facilitates the breaking of the mold body during deburring. The chip recovery is achieved by limiting and supporting the rear end of the workpiece through the limiting post 18. The mold body 2 has an internal cavity. From bottom to top, the cavity of the mold body 2 is equipped with a cylinder 3, a pad 4, and a fixing block 5. The pad 4 is fastened to the mold body 2 on both sides by bolts to achieve the connection between the pad 4 and the mold body 2. There are two fixing blocks 5 symmetrically arranged on the upper surface of the pad 4. The bottom of the fixing block 5 is fastened to the pad 4 by bolts. The top of the fixing block 5 is provided with fixing plates 13 on both sides. The fixing plates 13 are fastened to the mold body 2 by bolts to achieve the connection between the top of the fixing block 5 and the mold body 2, thereby ensuring that the fixing plate 13 is fastened to the mold body 2. To ensure the connectivity and stability of the ends, the fixing plate 13 abuts against the top of the guide groove 9 to ensure that the wedge 6 does not exceed the upper surface of the fixing block 5. The inner side of the fixing block 5 is inclined and has an inclined guide groove 9. There are two wedges 6, which respectively cooperate with the inclined inner side of the fixing block 5. The wedges 6 also cooperate with the guide groove 9 of the corresponding fixing block 5. The inner surface of the wedge 6 is provided with a first semi-circular hole 10 and a second semi-circular hole 11, which are interconnected. The top of the mold body 2 is provided with a tensioning protrusion 8, and the bottom of the tensioning protrusion 8 is connected to a connecting rod 12 by bolts. The top of the mold body 2 is provided with a through groove 14. 4. A channel 15 is connected to the bottom, and the channel 15 is interconnected with the cavity inside the mold body 2. The tensioning protrusion 8 is movably set in the through groove 14, and the connecting rod 12 is movably set in the channel 15 to realize the installation of the tensioning protrusion 8 and the connecting rod 12. The piston rod of the cylinder 3 faces and is connected to a pad 7. The pad 7 is connected to the bottom of the connecting rod 12. The pad 7 is cylindrical, and the outer surface of the lower part of the pad 7 is inclined so that when the piston of the cylinder 3 retracts, the pad 7 can smoothly pass through the two wedges 6. The outer periphery of the top of the pad 7 is chamfered so that when the piston of the cylinder 3 extends, the pad 7 can smoothly push open the two wedges 6 and will not cause the pad 7 to get stuck.

[0024] Assembly method and operating principle: Place the pad 4 in the middle of the cavity of the mold body 2, mate the wedge 6 with the guide groove 9 of the fixing block 5, and then place the two fixing blocks 5 with wedge 6 in the cavity of the mold body 2 and above the pad 4. At the same time, the fixing plate 13 on the upper surface of the fixing block 5 is fastened to the corresponding position of the mold body 2 by bolts to complete the installation of the fixing block 5. Next, cylinder 3 is installed at the bottom of the cavity of mold body 2, and cylinder 3 is fastened to mold body 2 with bolts. At this time, the pad 7 connected to the piston rod of cylinder 3 is located in the first semi-circular hole 10 and the second semi-circular hole 11 of the two wedges 6. At this time, the connecting rod 12 connected to the pad 7 passes through the channel 15 at the top of mold body 2. Finally, the tensioning protrusion 8 is connected to the top of the connecting rod 12 with bolts, and the tensioning protrusion 8 is located in the through groove 14 at the top of mold body 2. The receiving groove 17 and mold body 2 are installed at one end of the upper surface of mold base 1, and the limiting post 18 is installed at the other end of the upper surface of mold base 1 to complete the assembly. Mold base 1 is installed on the worktable of the spindle deburring machine, as shown. Figure 6 As shown. During operation, the workpiece is supported on the upper surface of the mold body 2. The holes on both sides of the workpiece to be deburred correspond to the mold holes 16 of the mold body 2. The piston rod of the cylinder 3 moves upward, driving the pad block 7 and the connecting rod 12 to move upward. During the upward movement of the pad block 7, the wedge block 6 moves outward and diagonally upward until the pad block 7 enters the first semi-circular hole 10 between the two wedge blocks 6. At this time, the stability of the connecting rod 12 is ensured by the guidance of the first semi-circular hole 10 and the pad block 7. The tensioning protrusion 8 presses against the lower surface of the workpiece (the upper surface of the workpiece is pressed by the pressing mechanism). This utility model has a reasonable structure. A cylinder 3 is installed inside the mold body 2. A pad 7 is installed on the piston rod of the cylinder 3. A connecting rod 12 is installed on the upper surface of the pad 7. A tensioning protrusion 8 is installed at the top of the mold body 2. The lower surface of the tensioning protrusion 8 is connected to the top of the connecting rod 12. The cylinder 3 drives the connecting rod 12 to rise, which in turn drives the tensioning protrusion 8 to rise, thus causing the tensioning protrusion 8 to clamp the lower surface of the workpiece. Compared with a method that only relies on a pressing mechanism cooperating with the mold body 2, the clamping stability is greatly improved, preventing the workpiece from slipping on the mold body 2. In case of loosening; at the same time, the mold body 2 is located above the pad 4 and has two symmetrically arranged fixing blocks 5. The inner side of the fixing block 5 is inclined and cooperates with the wedge block 6 through the guide groove 9. The inner surface of the wedge block 6 is provided with a first semi-circular hole 10 and a second semi-circular hole 11. When the pad 7 rises, the pad 7 pushes the wedge block 6 up until the pad 7 is located in the first semi-circular hole 10 of the two wedge blocks 6. At this time, the top of the wedge block 6 just abuts the fixing plate 13, thereby ensuring the stability of the pad 7, and thus ensuring the stability of the connecting rod 12 and the tensioning protrusion 8.
