When using the treatment equipment, one end of the nickel alloy rod is set at the output end of the motor 6, and then the second support tube 4 is manually controlled to rotate, and then the second support tube 4 is sleeved on the top of the nickel alloy rod, so that the grinding bar 702 is squeezed on the surface of the nickel alloy rod, and the nickel alloy rod is driven to rotate by the motor 6, so that the surface of the nickel alloy rod can be well polished by the grinding bar 702, so that the surface of the nickel alloy rod becomes smooth, which is convenient for the subsequent use of the nickel alloy rod to process the engine valve.

[0033] Reference Figures 2 to 6The adjusting device 7 includes a connecting frame 701, which is fixedly connected to the inner walls of the first supporting tube 3 and the second supporting tube 4. The inner wall of the connecting frame 701 is slidably connected with a grinding strip 702. The bottom of the grinding strip 702 is evenly fixedly connected with a first damping rod 703. The bottom of the first damping rod 703 is fixedly connected to the bottom of the inner wall of the connecting frame 701. The surface of the first damping rod 703 is sleeved with a first spring 704. One end of the first spring 704 is fixedly connected to the bottom of the grinding strip 702. One end of the first spring 704 close to the first damping rod 703 is fixedly connected to the bottom of the inner wall of the connecting frame 701. The bottom of the grinding strip 702 is fixedly connected with a triangular block 705. The triangular block 705 slides through and is inserted into the inner wall of the first supporting tube 3. The surfaces of the first support tube 3 and the second support tube 4 are slidably sleeved with a connecting ring 706, the inclined surface of the triangular block 705 is evenly provided with grooves 707, the inner wall of the groove 707 is fixedly connected with a rotating rod 708, and the surface of the rotating rod 708 is rotatably sleeved with a roller 709. When the adjusting device 7 is used, the connecting ring 706 is manually controlled to slide on the surfaces of the first support tube 3 and the second support tube 4, so that the connecting ring 706 squeezes the triangular block 705. When the connecting ring 706 squeezes the triangular block 705, the roller 709 is driven to rotate on the surface of the rotating rod 708, so that the connecting ring 706 can squeeze the triangular block 705 well. At this time, the first spring 704 pulls the grinding strip 702 toward the bottom of the inner wall of the connecting frame 701, and continues to move the connecting ring. The connecting ring 706 allows the grinding strip 702 to be well squeezed on the surface of the rod, so that the surface of nickel alloy rods of different specifications can be well polished. One side of the connecting frame 2 is fixedly connected to a support frame 710, and the inner wall of the support frame 710 is fixedly connected to a limiting rod 711, and the limiting rod 711 slides through and is inserted on one side of the connecting ring 706. One side of the connecting ring 706 is fixedly connected to a sliding bar 712, and one end of the sliding bar 712 is fixedly connected to one side of the connecting ring 706. A bolt 713 is inserted through a thread on one side of the sliding bar 712, and a circular plate 715 is rotatably sleeved on one end of the bolt 713. A protrusion 716 is evenly fixedly connected to the circular plate 715 away from the bolt 713. One side of the support frame 710 is fixedly connected to a rubber The connecting ring 706 is manually controlled to slide on the surface of the limiting rod 711, so that the connecting ring 706 can be driven to slide on the surface of the first supporting tube 3 and the second supporting tube 4, and at the same time, the sliding bar 712 can be driven to slide on the inner wall of the supporting frame 710. When the grinding strip 702 contacts the nickel alloy rod, the bolt 713 is manually controlled to rotate toward the inner wall of the sliding bar 712, so that the protrusion 716 is squeezed on one side of the rubber strip 714, which will cause the rubber to be squeezed and deformed, thereby well limiting the sliding bar 712 inside the supporting frame 710, so that the connecting ring 706 can be well fixed on the surface of the first supporting tube 3 and the second supporting tube 4. A first threaded rod 717 is inserted through a thread on one side of the supporting frame 710.A rotating frame 718 is rotatably sleeved on one end of the first threaded rod 717, and the rotating frame 718 is arranged at one end of the rod away from the first threaded rod 717. After connecting one end of the nickel alloy rod and the output end of the motor 6, the first threaded rod 717 is manually controlled to move toward the inside of the support frame 710, so that the rotating frame 718 is squeezed to the end of the rod away from the output end of the motor 6. When the rod is driven to rotate by the motor 6, the rotating frame 718 rotates at one end of the first threaded rod 717, which avoids affecting the rotation of the rod to a certain extent. A circular frame 719 is fixedly connected to the output end of the motor 6, and an extrusion rod 720 is inserted and inserted into the side of the circular frame 719 evenly slidingly. An arc plate 721 is fixedly connected to the end of the extrusion rod 720 close to the circular frame 719. The extrusion rod 720 is away from the arc One end of the plate 721 is fixedly connected to a moving bar 723, and one side of the circular frame 719 is fixedly connected to a support block 722.

The thread direction on the surface of the second threaded rod 724 is opposite from the middle to both sides. The middle section of the second threaded rod 724 is fixedly connected to a rotating wheel 725. Slide one end of the rod into the inside of the circular frame 719, and then manually drive the second threaded rod 724 to rotate through the rotating wheel 725. Because the thread direction on the surface of the second threaded rod 724 is opposite from the middle to both sides, the extrusion rod 720 can be driven close to the inside of the circular frame 719 through the moving bar 723, so that the arc plate 721 is squeezed on the surface of the rod, so that one end of the rod can be fixed inside the circular frame 719 fixedly connected to the output end of the motor 6.

This can well connect the two support plates 817 together, increase the bearing capacity of the two support plates 817 to a certain extent, and place the rod inside the two circular arc surfaces 804. This can prevent the rod from rotating at the bottom of the support plate 817 to a certain extent. One side of the rectangular plate 801 is slidably penetrated and inserted An L-shaped plate 807 is fixedly connected to one side of the L-shaped plate 807 with a second damping rod 808, an end of the second damping rod 808 close to the L-shaped plate 807 is fixedly connected to one side of the rectangular plate 801, a second spring 809 is sleeved on the surface of the second damping rod 808, one end of the second spring 809 is fixedly connected to one side of the L-shaped plate 807, an end of the second spring 809 close to the second damping rod 808 is fixedly connected to one side of the rectangular plate 801, and the L-shaped plate 807 is arranged on one side of the support plate 817. After the support plate 817 is inserted into the first support cylinder 3, the L-shaped plate 807 is manually passed through the rectangular plate 801, and then the L-shaped plate 807 is pulled toward the direction close to the rectangular plate 801 by the second spring 809, and then the L-shaped plate 807 is pulled through the L-shaped plate 80 The support plate 817 is limited inside the first support tube 3, the top of the rectangular plate 801 is fixedly connected with a sliding frame 810, the inner wall of the sliding frame 810 is slidably connected with a limiting frame 811, the limiting frame 811 is slidably sleeved on one side of the support plate 817, the bottom of the inner wall of the limiting frame 811 is fixedly connected with a third damping rod 812, the top of the third damping rod 812 is fixedly connected with the bottom of the limiting frame 811, the surface of the third damping rod 812 is sleeved with a third spring 813, one end of the third spring 813 is fixedly connected with the bottom of the inner wall of the sliding frame 810, one end of the third spring 813 close to the third damping rod 812 is fixedly connected with the bottom of the limiting frame 811, and the top side of the sliding frame 810 is fixedly connected with a fourth damping rod 814.The fourth damping rod 814 is fixedly connected to the end away from the sliding frame 810 with a blocking block 816, and the blocking block 816 is slidably sleeved on one side of the limit frame 811.

[0035] Working principle: when using the processing equipment, one end of the nickel alloy rod is set at the output end of the motor 6, and then the second support cylinder 4 is manually controlled to rotate, and then the second support cylinder 4 is sleeved on the top of the nickel alloy rod, so that the grinding bar 702 is squeezed on the surface of the nickel alloy rod, and the nickel alloy rod is driven to rotate by the motor 6, so that the surface of the nickel alloy rod can be well polished by the grinding bar 702, so that the surface of the nickel alloy rod becomes smooth. When using the adjustment device 7, first slide one end of the rod into the inside of the circular frame 719, and then manually drive the second threaded rod 724 to rotate through the rotating wheel 725. Because the thread direction on the surface of the second threaded rod 724 is opposite from the middle to both sides, the extrusion can be driven by the moving bar 723. The rod 720 is close to the inside of the circular frame 719, so that the arc plate 721 is squeezed on the surface of the rod, so that one end of the rod can be fixed inside the circular frame 719 fixedly connected to the output end of the motor 6. After one end of the nickel alloy rod is connected to the output end of the motor 6, the first threaded rod 717 is manually controlled to move toward the inside of the support frame 710, so that the rotating frame 718 is squeezed to the end of the rod away from the output end of the motor 6. When the rod is driven to rotate by the motor 6, the rotating frame 718 rotates at one end of the first threaded rod 717, which avoids affecting the rotation of the rod to a certain extent. The connecting ring 706 is manually controlled to slide on the surface of the limiting rod 711, which can drive the connecting ring 706 to move between the first support tube 3 and the second support tube. The surface of the support tube 4 slides, and at the same time drives the sliding bar 712 to slide on the inner wall of the support frame 710. When the grinding bar 702 contacts the nickel alloy rod, the bolt 713 is manually controlled to rotate toward the inner wall of the sliding bar 712, so that the protrusion 716 is squeezed on one side of the rubber strip 714, which will cause the rubber to be squeezed and deformed, and then the sliding bar 712 is well restricted inside the support frame 710. In this way, the connecting ring 706 can be well fixed on the surfaces of the first support tube 3 and the second support tube 4, so that the connecting ring 706 squeezes the triangular block 705. When the connecting ring 706 squeezes the triangular block 705, the roller 709 is driven to rotate on the surface of the rotating rod 708, so that the connecting ring 706 can be well squeezed. Triangular block 705, at this time, the first spring 704 pulls the grinding strip 702 toward the bottom of the inner wall of the connecting frame 701, and continues to move the connecting ring 706, so that the grinding strip 702 is well squeezed on the surface of the rod, so that the surface of nickel alloy rods of different specifications can be well polished. When using the supporting device 8, the supporting plate 817 is manually controlled to pass through the connecting frame 2 and then inserted into the first supporting tube 3. During the process of the supporting plate 817 sliding into the first supporting tube 3, the round block 802 slides on the inner wall of the slide groove 803. After the supporting plate 817 is inserted into the first supporting tube 3, the L-shaped plate 807 is manually passed through the rectangular plate 801, and then the L-shaped plate 807 is pulled toward the direction close to the rectangular plate 801 by the second spring 809.Then, the support plate 817 is restricted to the inside of the first support tube 3 through the L-shaped plate 807. At this time, the rectangular bar 806 is slid into the inside of the rectangular groove 805, so that the two support plates 817 can be well connected together, and the bearing capacity of the two support plates 817 can be increased to a certain extent. The rod can be placed inside the two arc surfaces 804, which can prevent the rod from rotating at the bottom of the support plate 817 to a certain extent. This makes it easier to fix one end of the rod to the output end of the motor 6 later. When the support device 8 is not in use, the support plate 817 is manually controlled to slide out of the first support tube 3 and the connecting frame 2, and then the round block 802 is manually controlled in the slide groove 803. The support plate 817 is rotated to make the support plate 817 vertically aligned with the bottom plate 1, and then the limit frame 811 is manually controlled to slide downward on the inner wall of the sliding frame 810, and the limit frame 811 is pulled toward the bottom of the sliding frame 810 by the third spring 813, so that the limit frame 811 is well limited to the top of the support plate 817. When the limit frame 811 is not in use, the limit frame 811 is manually slid to the top of the sliding frame 810, and then the positioning block 816 is set on one side of the limit frame 811, and then the positioning block 816 is pulled toward the direction close to the sliding frame 810 by the fourth spring 815, so that the limit frame 811 can be limited to the top of the sliding frame 810 by the positioning block 816.
