The end of the linkage slot rod away from the connecting short rod is provided with a waist groove, and the waist groove is slidably connected to the connecting short rod located on the front side. A spring is arranged on the outer side of the through rod, and the two ends of the spring are respectively fixedly connected to the force-bearing arc plate and the slide track. When the cutting and polishing workbench moves, the cutting and polishing workbench approaches the force-bearing arc plate, so that the force-bearing arc plate is forced to squeeze the spring to approach the slide track, and the two ends of the force-bearing arc plate push the connecting short rod on the slide rail connecting rod to be stressed, so that the slide rail connecting rod after being stressed slides along the slide track and approaches each other, and is driven along the slide track by the slide rail connecting rod. The connected pressure hinge blocks contact the edge of the dumbbell piece to fix the dumbbell piece to be processed, and the slide rail connecting rods are driven closer to each other through the pressure of the stress arc plate, and the extrusion mold is contacted and pressed by the pressure hinge blocks connected to the slide rail connecting rods to achieve positioning, thereby preventing the mold from offsetting during movement and improving the processing accuracy. At the same time, when the stress arc plate moves, the pitch thin rod will push the through rod to slide through the slide track, and the push rod hidden in the side groove of the slide track will be pushed out through the sliding of the through rod, and the push rod will contact the side of the dumbbell piece through the push rod to push the dumbbell piece flat and straighten it, thereby preventing the dumbbell piece from being positioned in an inclined state and affecting the processing effect.

The cam is fixedly connected to the guide rail, and the two ends of the spring are respectively fixedly connected to the touch block and the guide rail, and the two ends of the spring are respectively fixedly connected to the touch block and the guide rail. The material collecting box is connected and slidably connected to the lathe bed. When the slide rail connecting rod slides along the slide groove track, the connecting short rod connected to the slide rail connecting rod applies pressure and thrust to the guide groove, so that the two guide groove plates at the front and the rear are close to each other and close to the side of the dumbbell piece through the guide groove. When the dumbbell piece is polished and ground, the debris particles generated during the polishing and grinding process will fall into the guide groove plate and be introduced into the top of the collection table through the guide groove plate. When the processing is completed, the cutting and polishing workbench is moved to the far right side of the lathe bed, and the movement of the cutting and polishing workbench drives the pressure rod to squeeze the pressure block to move, so that the pressure block pulls the spring and stretches the pull rod during the movement, and the pull rod pulls the guide folding plate, so that the movement of the guide folding plate drives the push rod to move. The felt roller of the material plate moves, and the guide trough plate is guided into the collecting table, and the granular waste is pushed into the collecting box. The movement of the guide folding plate will push the extension rod to drive the platform guide plate and the collecting box to move, so that the collecting box can extend from the bottom of the collecting table to receive the protective oil pushed by the pushing plate.

At the same time, the lifting platform adjusts the installation connecting plate to the specified position, so that the installation connecting plate drives the card plate to be aligned with the top of the dumbbell piece. When the cutting and polishing workbench moves left and right, the coating roller connected to the inner side of the side seat plate first contacts the grinding part of the dumbbell piece. At this time, the coating roller is under pressure, which will cause the shaft to push the slide frame upward, and let the coating roller shaft slide along the inclined waist groove of the side seat plate. When the slide frame moves upward, it drives the material guide ramp and the material control cover plate to move upward together, so that the material control cover plate and the unloading trough slide relative to each other, so that the bottom side of the material control cover plate on the side notch of the unloading trough is exposed. At this time, the protective oil in the coating liquid box will be discharged from the side through the unloading trough. The protective oil is allowed to slide downward along the material guide ramp, so that the protective oil slides onto the coating roller, and the polished part of the dumbbell piece is protected. The coating roller contacts the dumbbell piece under pressure, and the material control cover plate and the material guide ramp slide relative to each other, thereby controlling the outflow of the protective oil from the coating tank. By controlling the outflow of the protective oil, the waste caused by the excess protective oil flowing out in advance or continuing to flow out after coating is avoided. At the same time, when the coating roller is no longer under pressure, the slide frame spring is reset, and the notch of the material discharge chute is blocked by the material control cover plate. At the same time, the excess protective oil in the material discharge chute is scraped off by the material control cover plate, and the excess protective oil is allowed to flow along the material guide ramp to the coating roller to avoid waste.

At this time, the connecting block on the bottom of the worktable plate is no longer restricted by the connecting square rod, and the worktable plate can be removed. By installing the worktable plate and using the small holes opened on the worktable plate, the protective oil dripping onto the worktable plate can be collected in the installed retention groove through the small holes to prevent the protective oil from being wasted.

[0035] An expansion mechanism 8 is provided on the bottom surface of the lathe bed 1, and the expansion mechanism 8 includes an expansion slot 81, a retention slot 82, a clamping strip 83, a connecting block 84, and a connecting square rod 85. The expansion slot 81 is fixedly connected to the bottom surface of the lathe bed 1, the retention slot 82 is slidably connected to the side of the expansion slot 81, the clamping strip 83 slides through the interior of the lathe bed 1, the connecting block 84 is fixedly connected to the bottom surface of the work table 2, and the connecting square rod 85 penetrates into the interior of the lathe bed 1. The clamping strip 83 and the connecting square rod 85 form a clamping structure, the connecting block 84 fits with the top surface of the lathe bed 1, and the connecting square rod 85 is plugged and connected to the connecting block 84. By installing the work table 2 and through the small holes opened on the work table 2, the protective oil dripping onto the work table 2 can be collected in the installed retention slot 82 through the small holes to prevent the protective oil from being wasted. Through this modular combination structure, the layout can be reasonably arranged according to the size of the processed parts, the expansion function can be increased, and the scope of application can be improved.

[0036] Working principle: First, when the cutting and polishing workbench 9 moves, the cutting and polishing workbench 9 approaches the stressed arc plate 54, so that the stressed arc plate 54 is forced to squeeze the spring to approach the slide track 51, and the two ends of the stressed arc plate 54 push the connecting short rod 53 on the slide rail connecting rod 52 to be stressed, so that the slide rail connecting rod 52 after being stressed slides along the slide track 51 and approaches each other, and the connected pressure hinge block 56 is driven by the slide rail connecting rod 52 along the slide track 51 to contact the edge of the dumbbell piece, and the dumbbell piece to be processed is fixed. The stress arc plate 54 is pressed to drive the slide rail connecting rod 52 closer to each other, and the pressure hinge block 56 connected to the slide rail connecting rod 52 contacts and presses the extrusion mold to achieve positioning, preventing the mold from offset during movement and improving the processing accuracy. At the same time, when the stress arc plate 54 moves, it will push the through rod 57 to slide through the slide groove track 51 through the pitch rod 58, and push the push rod 59 hidden in the side groove of the slide groove track 51 out through the sliding of the through rod 57, and contact the side of the dumbbell through the push rod 59.

[0037] Subsequently, when the slide rail connecting rod 52 slides along the slide groove track 51, the connecting short rod 53 connected to the slide rail connecting rod 52 applies pressure to the guide groove 61, so that the two guide groove plates 62, one in front and one behind, are close to each other and close to the side of the dumbbell piece through the guide groove 61. When the dumbbell piece is polished, the debris particles generated during the polishing process will fall into the guide groove plate 62 and be introduced into the top of the collection table 3 through the guide groove plate 62. When the processing is completed, the polishing workbench 9 is moved to the far right side of the lathe bed 1, and the movement of the polishing workbench 9 drives the pressure rod 612 to squeeze the touch block 68 to move, so that the spring is pulled and stretched during the movement of the touch block 68 The pull rod 67 pulls the guide folding plate 65, and the pull rod 67 pulls the guide folding plate 65 to move the felt roller 64 on the push plate 63, and the guide slot plate 62 is introduced into the collection table 3 and the granular waste is pushed into the collection box 611. The movement of the guide folding plate 65 will push the extension rod 69 to allow the extension rod 69 to drive the platform guide plate 610 and the collection box 611 to move, so that the collection box 611 extends from the bottom of the collection table 3 to receive the protective oil pushed by the push plate 63, and the granular waste is collected by the material guide to avoid falling on the workbench 2 after grinding. When the next group of dumbbell pieces are processed, the particles are easy to affect the flatness of the dumbbell pieces.

[0038] Then, the polishing workbench 9 is pushed together with the lifting platform 10, so that the lifting platform 10 adjusts the installation connecting plate 71 to the specified position, so that the installation connecting plate 71 drives the card plate 72 to be aligned with the upper part of the dumbbell piece. When the polishing workbench 9 moves left and right, the coating roller 75 connected to the inner side of the side seat plate 74 first contacts the grinding part of the dumbbell piece. At this time, the coating roller 75 is pressed to cause the rotating shaft to push the slide frame 76 to move up, and the rotating shaft of the coating roller 75 slides along the inclined waist groove of the side seat plate 74. When the slide frame 76 moves up, it drives the material guide ramp plate 77 and the material control cover plate 78 to move up together, so that the material control cover plate 78 and the discharge trough 79 slide relative to each other, so that the side notch of the discharge trough 79 The bottom side of the side control cover plate 78 is exposed. At this time, the protective oil in the coating liquid box 710 will be discharged from the side through the material discharge chute 79, and the protective oil will slide downward along the material guide ramp 77, so that the protective oil will slide onto the coating roller 75, and the grinding part of the dumbbell piece will be protected. The coating roller 75 contacts the dumbbell piece and is pressed to make the material control cover plate 78 and the material guide ramp 77 slide relative to each other, so as to control the outflow of the protective oil in the coating liquid box 710. By controlling the outflow of the protective oil, the waste caused by the excess protective oil flowing out in advance or continuing to flow out after coating is avoided. At the same time, when the coating roller 75 is no longer under pressure, the slide chute frame 76 spring is reset, and the notch of the material discharge chute 79 is blocked by the material control cover plate 78.

[0039] If it is necessary to replace the collecting table plate 3 or the working table plate 2 and the guide table plate 4, it is necessary to pull out the locking strip 83 from the side of the lathe bed 1 so that the locking strip 83 no longer jams the connecting square rod 85, and then pull out the connecting square rod 85 from the side of the lathe bed 1. At this time, the connecting block 84 on the bottom surface of the working table plate 2 is no longer restricted by the connecting square rod 85, and the working table plate 2 can be removed. By installing the working table plate 2 and through the small holes opened on the working table plate 2, the protective oil dripping onto the working table plate 2 can be collected in the installed retention groove 82 through the small holes to prevent waste of the protective oil.
