[0002] A centerless lathe is a cutting device that does not require centering and clamping of the workpiece. It mainly uses the spindle to drive the workpiece to rotate, and works with the cutting tool to achieve external cylindrical cutting. It is widely used in the mass production of cylindrical parts such as bearing rollers, pins, and bolts.

[0003] Existing centerless lathes have some shortcomings when cutting metal bars. The coordination between the feeding mechanism and the spindle speed is often insufficient, which can easily lead to problems such as workpiece slippage or positioning deviation. The cutting size of metal bars is relatively fixed and cannot be cut according to different sizes of metal bars as needed, which reduces the processing efficiency of metal bars and the adaptability of the lathe. To address these problems, a high-speed centerless lathe is proposed. Utility Model Content

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figures 1 to 4 As shown, this embodiment provides a high-speed centerless lathe, including a frame 1. A positioning frame 2 is fixedly installed on one side of the upper end of the frame 1. Multiple sets of drive motors are fixedly installed inside the positioning frame 2, and three sets of guide wheel groups 3 are rotatably installed on the outer wall of the positioning frame 2. Metal rods 4 are slidably connected between the guide wheel groups 3. One end of the metal rod 4 passes through the inside of the feeder box 5, and the extended end passes through the inside of the cutting frame 8. An adjustment structure 6 is provided at the upper end of the frame 1. The adjustment structure 6 includes a fixed frame 61 fixedly installed at the upper end of the frame 1, and an adjustment motor 62 is fixedly installed inside the fixed frame 61. An adjustment screw 63 is fixedly connected to the output end of the adjustment motor 62. A guide sleeve 66 is threadedly connected to the outer wall of the adjustment screw 63, and a cutting frame 8 is fixedly installed on the outer wall of the guide sleeve 66. Two cutting tools 82 are symmetrically arranged inside the cutting frame 8. A scale marking line 64 is fixedly provided on the outer wall of the fixed frame 61, and a cooling structure 7 is provided above the fixed frame 61.

[0018] like Figures 2 to 3As shown, the guide wheel assembly 3 is positioned opposite to the feeder housing 5, and the metal rod 4 is positioned opposite to the cutting frame 8. The extended end of the metal rod 4 is located inside another set of guide wheel assemblies 3. Two sets of guide slide rods 65 are symmetrically installed on the outer wall of the fixed frame 61. Limiting slide grooves 84 are symmetrically opened on the outer wall of the guide sleeve 66. The limiting slide grooves 84 are slidably connected to the outer walls of the two guide slide rods 65 respectively. Cutting cylinders 81 are fixedly installed at both the upper and lower ends of the cutting frame 8, and cutting blades 82 are fixedly connected to one end of each cutting cylinder 81. Guide sliders 83 are fixedly installed on both sides of the outer wall of the cutting blades 82, and the guide sliders 83 are slidably connected to the inner wall of the cutting frame 8. The two cutting blades 82 are positioned opposite to the metal rod 4.

[0019] By setting a scale mark line 64 on the outer wall of the fixed frame 61, it is easy to adjust the position of the cutting frame 8 on the guide sleeve 66 by adjusting the screw 63, which is relatively stable and can be adapted to cut metal bars 4 of different sizes. When the cutting blade 82 moves, it uses the guide slider 83 to move along the inner wall of the cutting blade 82 to accurately cut the outer wall of the metal bar 4.

[0020] like Figure 4 As shown, the cooling structure 7 includes a liquid storage tank 71 fixedly installed on the upper end of the fixed frame 61. A delivery pipe 73 is fixedly installed on the outer wall of the liquid storage tank 71, and a cooling pump 72 is fixedly connected to the outer wall of the delivery pipe 73. The cooling pump 72 is fixedly installed above the fixed frame 61. A positioning block 74 is fixedly installed on the outer wall of the delivery pipe 73. The positioning block 74 is fixedly installed on the outer wall of the cutting frame 8. An atomizing nozzle 75 is fixedly connected to the extended end of the delivery pipe 73, and the atomizing nozzle 75 is positioned opposite to the cutting area.

[0021] By setting a positioning block 74 on the outside of the conveying pipe 73, the conveying pipe 73 can be positioned easily. At the same time, the atomizing nozzle 75 is aligned with the cutting area, thereby cooling the cutting tool 82 and improving its service life.

[0022] The operating principle and process of this utility model are as follows: The operator presets the parameter values ​​of the guide wheel assembly 3, the feeding machine box 5, the adjusting motor 62, and the cutting cylinder 81 on the controller. The metal rod 4 is passed through the three guide wheel assemblies 3, with one end passing through the feeding machine box 5. The drive motor rotates the three guide wheel assemblies 3, causing one end of the metal rod 4 to pass through the cutting frame 8, facilitating the positioning of the metal rod 4. Based on the cutting requirements of the metal rod's size, the adjusting motor 62 inside the drive frame 61 drives the adjusting screw... Rotating rod 63 causes adjusting screw 63 to move the cutting frame 8 on the outside of guide sleeve 66. When the cutting frame 8 moves to the standard distance using scale marking line 64, it stops moving. By driving two cutting cylinders 81, the cutting blade 82 moves relative to each other to perform a precise cutting operation on the metal bar 4. At the same time, by driving the cooling pump 72, the coolant in the storage tank 71 is sprayed out from the atomizing nozzle 75 through the delivery pipe 73 to cool the cutting area, which facilitates the cooling of the cutting blade 82 and improves its service life.
