[0025] The present invention will be further described below in conjunction with the accompanying drawings:

[0026] Please refer to Figure 1-12 A high-efficiency semi-round iron drilling machine includes a frame 1 and a feeding mechanism 2 and a drilling mechanism 3 arranged on the frame 1. The feeding mechanism 2 is arranged in the middle of the frame 1, and the drilling mechanism 3 is arranged on one side of the feeding mechanism 2. The feeding mechanism 2 includes a vibration plate 21, an arranging frame 22, a feeding rod 23, a fixing frame 24 and a positioning frame 25. The vibration plate 21 vibrates and arranges the semi-round iron 5 and then transports it to the arranging frame 22, so that the semi-round iron 5 is stacked in the arranging frame 22 in sequence. A feeding rod 23 driven by a cylinder is provided on one side of the arranging frame 22. The feeding rod 23 pushes the semi-round iron 5 at the bottom of the arranging frame 22 into the fixing frame 24. Figure 5 and Fig.10The fixing frame 24 includes a downward pressure cylinder 241, a lower fixing block 242 and an upper fixing block 243. A fixing groove corresponding to the structure of the semi-circular iron 5 is provided between the lower fixing block 242 and the upper fixing block 243. The fixing groove is formed by the lower fixing block 242 and the upper fixing block 243. The semi-circular iron 5 is pushed into the fixing groove by the feeding rod 23. When in use, the downward pressure cylinder 241 can drive the upper fixing block 243 to move up and down. The movement distance is generally within 5 mm, with 2 mm being the best. When the feeding rod 23 pushes the semi-circular iron 5 to move in the fixing groove, the downward pressure cylinder 241 can drive the upper fixing block 243 to move upward, so that the semi-circular iron 5 can move smoothly in the fixing groove. When the semi-circular iron 5 is moved into place, the downward pressure cylinder 241 drives the upper fixing block 243 to move downward to press the semi-circular iron 5, so as to prevent the semi-circular iron 5 from being displaced when the drilling mechanism 3 is drilling. The positioning frame 25 includes a mounting block 251 arranged on the upper fixed block 243, a movable block 252 pivotally connected to the mounting block 251, a tension spring 253 arranged between the mounting block 251 and the movable block 252, an adjusting rod 1 254 and an adjusting rod 2 255. The mounting block 251 and the movable block 252 form an N-shape that can adjust the angle. One end of the adjusting rod 1 254 is screwed onto the movable block 252, and the other end is pressed against the mounting block 251 under the action of the tension spring 253. One end of the adjusting rod 255 is arranged on the movable block 252, and the other end is pressed against one end of the semi-circular iron 5 under the action of the tension spring 253. In normal use, the positioning frame 25 is used in conjunction with the feeding rod 23. When the feeding rod 23 pushes the semi-circular iron 5 into place, one end of the semi-circular iron 5 is located between the feeding rod 23 and the adjusting rod 2 255, thereby positioning the semi-circular iron 5. Fig.10When the semi-circular iron 5 is drilled, the feeding rod 23 will reset to the left, and the semi-circular iron 5 located in the arranging frame 22 will drop to the bottom, and the feeding rod 23 will move to the right again to push the semi-circular iron 5 under the arranging frame 22 into the fixed groove of the fixing frame 24. The semi-circular iron 5 in the original fixing frame 24 is pushed by the thrust from the left side to push the movable block 252 of the positioning frame 25 to rotate, so that the rightmost semi-circular iron 5 is discharged from the fixing frame 24; the drilling mechanism 3 includes: a bottom plate 31, a guide rail device 32, a slide plate 33, a driving device 34, a motor 35 and an output shaft 36, the bottom plate 31 is arranged on the frame 1, and the guide rail device 32 is installed between the bottom plate 31 and the slide plate The guide rail device 32 includes a slider installed under the slide plate 33 and a guide rail installed on the bottom plate 31. The slider moves along the guide rail. The motor 35 and the output shaft 36 are installed on the slide plate 33. A drill bit 37 is clamped on the output shaft 36. There are multiple output shafts 36. The present invention is configured with two output shafts 36, which respectively drill two through holes 51 on the semi-circular iron 5. The output shaft 36 is driven to rotate by the motor 35. The driving device 34 drives the slide plate 33 to move back and forth along the guide rail device 32, thereby driving the output shaft 36 to drill holes in the semi-circular iron 5. The driving device 34 can be selected in a variety of ways. The present invention selects a cylinder.

[0027] Further technical solution: The drilling mechanism 3 is also provided with a buffer device 39, and the output end of the buffer device 39 is connected to the slide plate 33. The buffer device 39 of the present invention uses a cylinder. The semi-circular iron 5 has different sizes. The large semi-circular iron 5 requires a larger through hole 51 and a larger drill bit 37, and also requires a larger driving force of the driving device 34. In order to fit the semi-circular iron 5 of multiple sizes, the driving device 34 is selected to meet the needs of the semi-circular iron 5 of the largest size. However, when using it, when a small drill bit 37 is used to drill a semi-circular iron 5, the small drill bit 37 is easily broken due to the excessive thrust of the driving device 34. In order to solve the above technical problems, a buffer device 39 is set. When drilling is required, the driving device 34 pushes the slide plate 33 forward to drill, and the buffer device 39 generates an opposite force to reduce the driving force of the driving device 34. The buffer device 39 is provided with an adjustment valve, such as an air pressure adjustment valve, to adjust the force of the buffer device 39.

[0028] Further technical solution: The arrangement frame 22 includes a front plate 221, a rear plate 222 and a stopper 223. A gap for stacking semi-circular irons 5 is formed between the front plate 221 and the rear plate 222. A stopper 223 is provided at one end of the gap. The stopper 223 is set at a height at or above the second semi-circular iron 5 from the bottom to ensure that the feeding rod 23 pushes the lowest semi-circular iron 5 out from the bottom of the gap.

[0029] Further technical solution: The arrangement frame 22 also includes a guide block 224, and the upper end surface of the guide block 224 is an inclined surface, such as Fig.11 The setting of the inclined plane makes the center of gravity of the semicircular iron 5 deviate to one side of the plane of the semicircular iron 5, ensuring that one side of the plane is in a vertical state.

[0030] A further technical solution is as follows: one end of the second adjusting rod 255 is screwed onto the movable block 252 , and the length of the second adjusting rod 255 is adjusted to adapt to semi-circular irons 5 of different sizes.

[0031] A further technical solution includes a deburring mechanism 4 disposed on the other side of the feeding mechanism 2, wherein the deburring mechanism 4 includes: The bottom plate 41, the guide rail device 42, the slide plate 43, the drive device 44, the motor 45 and the output shaft 46, the bottom plate 41 is arranged on the frame 1, the guide rail device 42 is installed between the bottom plate 41 and the slide plate 43, the guide rail device 42 includes a slider installed under the slide plate 43 and a guide rail installed on the bottom plate 41, the slider moves along the guide rail, the motor 45 and the output shaft 46 are installed on the slide plate 43, a drill bit 47 is clamped on the output shaft 46, and a plurality of output shafts 46 are arranged. The present invention is arranged with two output shafts 46, which respectively correspond to the two through holes 51 on the semi-circular iron 5, the output shaft 46 is driven to rotate by the motor 45, the drive device 44 drives the slide plate 43 to move back and forth along the guide rail device 42, thereby driving the output shaft 46 to clean the burrs 52 on the through hole 51 on the semi-circular iron 5, and the drive device 44 can be selected in a variety of ways. The present invention selects a cylinder, such as Figure 8 and Fig. 9 When the drilling mechanism 3 drills a through hole 51 from one side of the semi-circular iron 5, a burr 52 will be generated on the other side of the semi-circular iron 5. Due to the process requirements, the burr 52 needs to be removed. The principle of removing the burr 52 is to use a larger drill bit 37 to clean the burr 52 by drilling. The depth of the drilling is limited to removing the burr 52. The deburring mechanism 4 is set at a position that is one semi-circular iron 5 away from the drilling mechanism 3. Figure 8 The top semi-circular iron 5 is pushed by the feeding rod 23, the middle semi-circular iron 5 is drilled by the drilling mechanism 3, and the bottom semi-circular iron 5 is deburred by the deburring mechanism 4. When the drilling mechanism 3 completes the drilling, the feeding rod 23 pushes the drilled semi-circular iron 5 to the bottom. At this time, the drilling mechanism 3 drills the new semi-circular iron 5, and the deburring mechanism 4 cleans the burrs 52 on the bottom semi-circular iron 5, so that drilling and deburring are carried out simultaneously, and the production efficiency is high.

[0032] The above description does not limit the technical scope of the present invention in any way. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
