Description

Technical Field

[0001] This utility model relates to the field of lathe machining technology, and specifically to a drilling mechanism for lathe machining. Background Technology

[0002] Lathes are mainly used for machining shafts, discs, sleeves, and other workpieces with rotating surfaces. They are one of the most widely used machine tools in machinery manufacturing and repair shops. Lathe drilling is a hole-making method performed on a lathe. By rotating the drill bit, it cuts on the surface of the workpiece to form a hole of the desired shape. In this process, the lathe spindle drives the drill bit to rotate at high speed, while the workpiece moves along the axial direction under the fixation of the lathe fixture. By controlling the spindle speed and the workpiece movement speed, the diameter and depth of the hole can be precisely controlled.

[0003] Over time, drill bits may undergo micro-deformation due to factors such as processing extrusion, processing wear, and temperature rise. However, when the drill bit undergoes micro-deformation, the accuracy of drilling will decrease. However, micro-deformation of the drill bit is not easily observed by the operator with the naked eye. Therefore, drill bits that are prone to micro-deformation are still used.

[0004] To address the aforementioned problems, this application proposes a drilling mechanism for lathe machining. Utility Model Content

[0005] This utility model addresses the technical problems existing in the prior art by providing a drilling mechanism for lathe machining.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A drilling mechanism for lathe machining includes a fixed ring mounted on a hydraulic rod of the lathe drilling mechanism. The fixed ring is provided with a warning structure, which includes an electric telescopic rod mounted on the fixed ring and an alarm mounted on the hydraulic rod of the lathe drilling mechanism. A motor is installed at the telescopic end of the electric telescopic rod, and a mounting rod is installed at the output end of the motor. A mounting ring is installed at one end of the mounting rod. An annular groove is formed on the inner side of the mounting ring. A touch ring is movably placed on the mounting ring through the annular groove. The inner diameter of the touch ring is equal to the outer diameter of the drill bit. A mounting groove is formed on the mounting ring through the annular groove. A spring is installed on the mounting ring through the mounting groove. A connecting piece is installed at one end of the spring. One side of the connecting piece is connected to the touch ring. A switch is installed on the mounting ring through the annular groove. The touch end of the switch contacts the outer side of the touch ring. The switch is electrically connected to the alarm.

[0007] The retaining ring is provided with a lubrication structure.

[0008] The lubrication structure includes a U-shaped block with an oil groove on it and an oil drain hole at the bottom of the oil groove. The mounting ring has an oil inlet hole that communicates with the annular groove and is located directly below the oil drain hole. The mounting ring has an oil outlet hole through the mounting groove. The lubrication structure is used to lubricate the spring.

[0009] The U-shaped block is connected to a bolt via an oil groove thread. The bolt is used to block the top of the oil groove.

[0010] A mounting bracket is installed on the fixing ring, and the U-shaped block is installed on the mounting bracket. The mounting bracket is used to support the U-shaped block.

[0011] The U-shaped block has an operating groove, and a mounting shell is installed on the U-shaped block through the operating groove. A torsion spring is installed inside the mounting shell. The U-shaped block is rotatably connected to a rotating rod through the operating groove. One end of the torsion spring is connected to the outside of the rotating rod. A connecting plate is installed on the rotating rod, and a blocking column is installed on the connecting plate. The top of the blocking column is in contact with the oil outlet end of the lower oil hole. The operating groove, mounting shell, torsion spring, rotating rod, connecting plate, and blocking column are used to block the lower oil hole.

[0012] The plugging column is specifically made of rubber.

[0013] The beneficial effects of this utility model are:

[0014] By setting up a warning structure, after each drilling is completed, the motor is started so that the mounting ring is directly below the drill bit. Then, the electric telescopic rod is started so that its telescopic end moves the mounting ring upward. If the touching ring touches the drill bit, the touching ring moves to squeeze the switch, causing the alarm to sound, thereby reminding the operator that the drill bit has undergone slight deformation. This helps the operator to detect the slight deformation of the drill bit in time.

[0015] By setting up a lubrication structure, when the warning structure is not in use, the mounting ring moves to the inside of the U-shaped block, and the lubricating oil flows into the oil inlet through the lower oil hole to lubricate the spring;

[0016] When the warning structure is in use, the mounting ring disengages from the U-shaped block, and the torsion spring resets with the help of torque, thereby driving the rotation of the rotating rod, which in turn drives the rotation of the connecting plate. The rotation of the connecting plate drives the rotation of the plugging column, thereby causing the plugging column to block the lower oil hole and minimizing oil dripping from the lower oil hole.

[0029] Reference Figure 1-3 A drilling mechanism for lathe machining includes a fixed ring 1 mounted on a hydraulic rod of the lathe drilling mechanism. The fixed ring 1 has a warning structure 2, which includes an electric telescopic rod 201 mounted on the fixed ring 1 and an alarm 211 mounted on the hydraulic rod of the lathe drilling mechanism. A motor 202 is mounted on the telescopic end of the electric telescopic rod 201, and a mounting rod 203 is mounted on the output end of the motor 202. A mounting ring 204 is mounted on one end of the mounting rod 203. An annular groove 205 is formed on the inner side of the mounting ring 204. A touch ring 206 is movably placed on the mounting ring 204 through the annular groove 205. The inner diameter of the touch ring 206 is equal to the outer diameter of the drill bit. A mounting groove 208 is formed on the mounting ring 204 through the annular groove 205. A spring 209 is mounted on the mounting ring 204 through the mounting groove 208. A connecting piece 210 is mounted on one end of the spring 209. One side of 10 is connected to the touch ring 206. The mounting ring 204 is equipped with a switch 207 through the annular groove 205. The touch end of the switch 207 is in contact with the outer side of the touch ring 206. The switch 207 is electrically connected to the alarm 211. According to the above technical solution, specifically, each time drilling is completed, the extension end of the hydraulic rod on the lathe drilling mechanism drives the drill bit to move up. Then, the motor 202 is started, which drives the mounting rod 203 to rotate. The rotation of the mounting rod 203 drives the rotation of the mounting ring 204, so that the mounting ring 204 is located directly below the drill bit. Then, the electric extension rod 201 is started, which drives the mounting ring 204 to move up. If the touch ring 206 touches the drill bit, the touch ring 206 moves to squeeze the switch 207, which causes the alarm 211 to sound, thereby reminding the operator that the drill bit has undergone slight deformation, which helps the operator to detect the slight deformation of the drill bit in time.

[0030] Among them, switch 207 is specifically model Omron micro tactile switch B3F-4055, and alarm 211 is specifically model SONITRON alarm SMAC-25. The circuit layout of the two can be reasonably set according to the actual situation, and the signal transmission method of the two is existing technology.

[0031] Reference Figure 1 , Figure 4 and Figure 5 The fixed ring 1 is provided with a lubrication structure 3, which includes a U-shaped block 302. The U-shaped block 302 has an oil groove 303 for holding lubricating oil. The bottom of the oil groove 303 has an oil drain hole 305. The mounting ring 204 has an oil inlet hole 306 that communicates with the annular groove 205. The oil inlet hole 306 is located directly below the oil drain hole 305. The mounting ring 204 has an oil outlet hole 313 through the mounting groove 208. When the warning structure 2 is not in use, the mounting ring 204 moves to the inside of the U-shaped block 302. At this time, the lubricating oil flows into the oil inlet hole 306 through the oil drain hole 305 to lubricate the spring 209. Then, the oil can be discharged through the oil outlet hole 313.

[0032] Reference Figure 4 and Figure 5 The U-shaped block 302 is threadedly connected to the oil groove 303 by a bolt 304, which is used to block the top of the oil groove 303.

[0033] Reference Figure 1 A mounting bracket 301 is installed on the fixing ring 1, and a U-shaped block 302 is installed on the mounting bracket 301. The mounting bracket 301 is used to support the U-shaped block 302.

[0034] Reference Figure 5 The U-shaped block 302 has an operating groove 307. A mounting shell 308 is installed on the U-shaped block 302 through the operating groove 307. A torsion spring 309 is installed inside the mounting shell 308. A rotating rod 310 is rotatably connected to the U-shaped block 302 through the operating groove 307. One end of the torsion spring 309 is connected to the outside of the rotating rod 310. A connecting plate 311 is installed on the rotating rod 310. A blocking post 312 is installed on the connecting plate 311. The top end of the blocking post 312 is connected to the lower oil hole. The oil outlet end of 305 is in contact with the plug. The plug column 312 is made of rubber. When the warning structure 2 is in use, the mounting ring 204 is disengaged from the U-shaped block 302. At this time, the torsion spring 309 is reset by torque, which drives the rotating rod 310 to rotate, and then drives the connecting plate 311 to rotate. The rotation of the connecting plate 311 drives the rotation of the plug column 312, so that the plug column 312 blocks the lower oil hole 305, thus avoiding oil dripping from the lower oil hole 305 as much as possible.

[0035] Working principle:

[0036] In this lathe drilling mechanism, after each drilling operation, the drill bit is moved upward by the extension end of the hydraulic rod on the drilling mechanism. Then, the motor 202 is started, which drives the mounting rod 203 to rotate. The rotation of the mounting rod 203 drives the rotation of the mounting ring 204, so that the mounting ring 204 is located directly below the drill bit. Then, the electric telescopic rod 201 is started, and its extension end drives the mounting ring 204 to move upward. If the touch ring 206 touches the drill bit, the touch ring 206 moves the squeeze switch 207, which causes the alarm 211 to sound, thereby reminding the operator that the drill bit has undergone slight deformation, which helps the operator to detect the slight deformation of the drill bit in time.

[0037] When the warning structure 2 is not in use, the drilling mechanism of the lathe moves the mounting ring 204 to the inside of the U-shaped block 302. At this time, lubricating oil flows into the oil inlet 306 through the lower oil hole 305 to lubricate the spring 209. Subsequently, the oil can be discharged through the oil outlet 313.

[0038] When the warning structure 2 is in use, the mounting ring 204 disengages from the U-shaped block 302 during the drilling mechanism of the lathe. At this time, the torsion spring 309 resets with the help of torque, thereby driving the rotation of the rotating rod 310, which in turn drives the rotation of the connecting plate 311. The rotation of the connecting plate 311 drives the rotation of the blocking column 312, thereby causing the blocking column 312 to block the lower oil hole 305, thus minimizing the dripping of oil from the lower oil hole 305.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0040] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
