When the worker uses a conventional wheel cutting machine for cutting, if the workpiece is heavy and the number of workpieces to be cut is large, the worker has to move the remaining parts after cutting a section of the workpiece, which results in low work efficiency, and each time the worker bends down to move the workpiece, the labor intensity increases. The cost of using fully automatic cutting equipment is too high. Therefore, the cutting machine is further optimized. Utility Model Content

DETAILED DESCRIPTION

[0018] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0019] like Figure 1 , 2 As shown, the embodiment of the utility model proposes a self-feeding cutting machine, the cutting machine includes a workbench 3 and a tool holder 1 rotatably connected to the top surface of the workbench 3, a knife disc 8 is rotatably connected to the tool holder 1, and a motor driving the knife disc 8 to rotate is fixed on the tool holder 1. The cutting machine includes a guide rod 7, a sliding block 4, a motor 9, an electromagnetic sucker 5, and an elastic connecting rod 15. The guide rod 7 is horizontally arranged and perpendicular to the plane where the knife disc 8 on the tool holder 1 is located, and one end of the guide rod 7 is fixedly connected to one side of the tool holder 1. The sliding block 4 is slidably connected to the guide rod 7, the motor 9 is fixedly connected to the sliding block 4, a main gear 10 is arranged on the output shaft of the motor 9, and a bar gear is arranged on the guide rod 7, and the main gear 10 is meshed with the bar gear. The elastic connecting rod 15 is arranged vertically, the top end of the elastic connecting rod 15 is fixedly connected to the sliding block 4, and the bottom end of the elastic connecting rod 15 is fixedly connected to the electromagnetic sucker 5. An operating rod 2 is provided on the tool holder 1, and a worker moves the operating rod 2 up and down so that the tool disc 8 cuts the workpiece.

[0020] Preferably, a plurality of lower fixing blocks 16 are arranged in parallel on the workbench 3, the arrangement direction of the lower fixing blocks 16 is perpendicular to the plane where the cutter disc 8 is located and is located below the cutter disc 8, and a concave arc surface is provided on the top of the lower fixing block 16. When the workpiece needs to be positioned during processing on the workbench 3, the concave arc surface prevents the workpiece from shifting laterally.

[0021] like Figure 2 As shown, preferably, the elastic connecting rod 15 includes a fixed sleeve 12, a sliding rod 11 and a spring 13, the fixed sleeve 12 is arranged vertically, the bottom end of the fixed sleeve 12 is fixedly connected to the top surface of the electromagnetic suction cup 5, a sliding hole is arranged inside the fixed sleeve 12, the lower section of the sliding rod 11 is slidably connected to the sliding hole of the fixed sleeve 12, the top of the sliding rod 11 is fixedly connected to the sliding block 4, the spring 13 is coaxial with the fixed sleeve 12 and arranged in the sliding hole of the fixed sleeve 12, one end of the spring 13 is fixedly connected to the sliding rod 11, and the other end of the spring 13 is fixedly connected to the bottom of the sliding hole of the fixed sleeve 12. When the elastic connecting rod 15 is in the initial state, the electromagnetic suction cup 5 is located below the cutter disc 8. When the staff presses the operating rod 2 downward, the electromagnetic suction cup 5 first engages the workpiece with the lower fixed block 16, and then the elastic connecting rod 15 contracts, and the cutter disc 8 continues to descend to cut the workpiece. The elastic connecting rod 15 will not affect the cutter disc 8 from continuing to move downward.

[0022] Preferably, the bottom surface of the electromagnetic chuck 5 is provided with an arc surface opening downward. When the tool holder 1 and the tool disc 8 move downward, the distance between the electromagnetic chuck 5 and the lower fixed block 16 is reduced, squeezing the workpiece. To prevent the workpiece and the electromagnetic chuck 5 from displacement, the arc surface of the electromagnetic chuck 5 and the lower fixed block 16 are closed to clamp the workpiece, that is, the two arc surfaces with two openings facing each other are closed to fix the workpiece. In this embodiment, the bottom surface of the electromagnetic chuck 5 is provided with a rubber layer 17 for anti-slip.

[0023] Preferably, a pull rod 14 is further included, one end of which is fixedly connected to the end of the guide rod 7 away from the tool holder 1, and the other end of the pull rod 14 is tilted upward and fixedly connected to the tool holder 1. When the sliding block 4 moves to the side away from the tool holder 1, one end of the guide rod 7 is easily bent and broken by the force, and the pull rod 14 increases the upper limit of the load of the guide rod 7. When the workpiece holder is heavy, the guide rod 7 transfers the gravity to the tool holder 1.

[0024] Preferably, a scale is provided on the guide rod 7 to facilitate the staff to check the feed amount of the electromagnetic suction cup 5 on the sliding block 4 driving the workpiece to move horizontally, thereby improving practicality.

[0025] Preferably, a counterweight block 6 is provided on the side of the tool holder 1 away from the guide rod 7. This prevents one side of the tool holder 1 from being too heavy, so that the cutter disc 8 or the tool holder 1 may tilt after the cutting machine is used for a long time.

[0026] like Figure 3 As shown, preferably, a square hole is provided in the sliding block 4, a groove 18 is provided on the top surface of the guide rod 7, and the bar teeth are arranged in the groove 18. When the square hole on the sliding block 4 and the guide rod 7 are slidably matched, the sliding block 4 will not rotate around the guide rod 7.

[0027] Working steps: When cutting the workpiece, place the workpiece on the lower fixed block 16 below the guide rod 7, with one end of the workpiece close to the cutter disc 8. Then move the sliding block 4 to the side of the guide rod 7 away from the tool holder 1, and the staff moves the operating rod 2 downward, so that the electromagnetic suction cup 5 moves downward and contacts the workpiece, and then the electromagnetic suction cup 5 sucks the workpiece, and the electromagnetic suction cup 5 moves upward a little distance to make it leave the lower fixed block 16 to facilitate the sliding of the workpiece, and the motor 9 drives the sliding block 4 to move in the direction close to the cutter disc 8, and part of the workpiece will move to the other end of the cutter disc 8, and the staff presses the operating rod 2 downward, and the cutter disc 8 completes the cutting of the workpiece, and so on.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
