Description

Technical Field

[0001] This utility model relates to the field of tool runout measurement and correction technology, specifically a tool runout correction device for processing equipment. Background Technology

[0002] In the machining process of all CNC machining centers, many cutting tools are required for machining. During the assembly of these tools with collets and tool holders, due to the accuracy errors of the tools, tool holders and collets, they are assembled together and then mounted on the machine tool spindle. During machining, assembly accuracy errors will occur, which will cause the product machining accuracy to be unreliable. These errors will cause deviations from the ideal machining path accuracy during the cutting process, ultimately leading to out-of-tolerance phenomena in the machined product dimensions. This tool and tool holder assembly error is called tool runout.

[0003] According to a public announcement (Announcement No.: CN221495314U3), a CNC cutting tool runout measurement and correction device is proposed. This device enables offline measurement and rapid correction of tool runout, solving the problems of time-consuming, labor-intensive, and slow correction methods that occupy production equipment and disrupt production. During tool runout measurement, a cylinder pusher actuates a simulated spindle pull rod, which in turn compresses a stacked spring, causing the four-lobed jaws to open and release the tool holder. When the cylinder retracts, the simulated spindle pull rod retracts autonomously under the spring's rebound, and the four-lobed jaws close, automatically clamping the tool holder, thus improving installation efficiency.

[0004] However, in actual use, the above-mentioned equipment still requires manual rotation of the tool to detect tool runout. Manual rotation is likely to result in uneven rotational power, which will cause measurement contact errors. Furthermore, after the error is measured, the tool needs to be manually repaired with a rubber hammer, which may cause accidental damage to the tool. In view of this, we propose a tool runout correction device for processing equipment. Summary of the Invention

[0017] like Figures 1-4As shown, this utility model provides a technical solution: a tool runout correction device for processing equipment, including a worktable 1, a support leg 11 fixedly connected to the lower surface of the worktable 1, a fixed frame 12 fixedly connected to the upper surface of the worktable 1, and a mounting frame 13 fixedly connected to the upper surface of the worktable 1. A mounting mechanism 2 is provided inside the mounting frame 13. The mounting mechanism 2 includes: an equipment groove 21, a roller groove 22, a pulley 23, a mounting groove 24, a magnet 25, a mounting rod 26, a movable frame 27, a fixed sleeve 28, a telescopic spring 29, a sliding rod 210, a connecting frame 211, a motor 212, and a roller 213.

[0018] In one embodiment of this utility model, a device groove 21 is formed on the upper surface of the mounting frame 13. A roller groove 22 is formed on the side wall of the device groove 21, and a pulley 23 is rotatably connected to the side wall of the roller groove 22. A mounting groove 24 is formed on the upper surface of the mounting frame 13, and a magnet 25 is fixedly connected to the upper surface of the mounting frame 13. A mounting rod 26 is rotatably connected to the inner wall of the mounting groove 24. The bottom surface of the movable frame 27 is fixedly connected to the upper surface of the mounting rod 26. A fixing sleeve 28 is fixedly connected to the top surface of the movable frame 27. One end of a telescopic spring 29 is fixedly connected to the inner top surface of the fixing sleeve 28. The other end is fixedly connected to a slide rod 210, the bottom surface of the slide rod 210 is fixedly connected to a connecting frame 211, the side wall of the connecting frame 211 is fixedly connected to a motor 212, the outer wall of the output end of the motor 212 is fixedly connected to a roller 213, the mounting groove 24 is set on one side of the equipment groove 21 on the upper surface of the mounting frame 13, the magnet 25 is set on the other side of the equipment groove 21 on the upper surface of the mounting frame 13, the equipment groove 21 is shaped as an inverted triangle, and the bottom surface of the movable frame 27 is fixedly connected to a magnet 25 with opposite magnetic poles to the magnet 25, the side wall of the movable frame 27 is fixedly connected to a pull ring, and the upper surface of the movable frame 27 is fixedly connected to a pull ring. A through groove matching the inner wall size of the fixed sleeve 28 is provided. The size of the slide rod 210 matches the inner wall size of the fixed sleeve 28. When installing the tool, the movable frame 27 is first rotated by the pull ring to open the position of the equipment slot 21. Then, the tool is placed inside the equipment slot 21. The equipment slot 21, which is shaped like an inverted triangle, can adapt to different tool sizes. Then, the movable frame 27 is reset by the pull ring. The movable frame 27 always rotates around the direction of the mounting slot 24 and the mounting rod 26. After the tool is placed, the telescopic spring 29... The slide bar 210 can be pushed towards the tool to press, which will further drive the connecting frame 211 and the roller 213 to abut against the outer surface of the tool for transmission connection. After the motor 212 is started, the rotating roller 213 can drive the tool to rotate stably and evenly, so that the calibration mechanism 4 can easily calibrate and inspect the tool. By setting magnets 25 with opposite magnetic poles on the bottom surface of the mounting frame 13 and the movable frame 27, the position of the movable frame 27 can be easily fixed. When the tool rotates, the pulley 23 set in the roller groove 22 abuts against the outer surface of the tool, giving the tool a stable support force.

[0019] In addition, one end of the limiting rod 3 is fixedly connected to the side wall of the mounting frame 13, and the other end of the limiting rod 3 is fixedly connected to one end of the fixed frame 12 close to the mounting frame 13. A connecting block 31 is slidably connected to the outer surface of the limiting rod 3. The upper surface of the connecting block 31 is fixedly connected to a support arm 32. The number of the limiting rods 3 is set to two groups, and the two groups of limiting rods 3 are symmetrically distributed in a mirror image on the side wall of the mounting frame 13. By fixedly connecting two groups of limiting rods 3 symmetrically distributed in a mirror image between the mounting frame 13 and the fixed frame 12, the stable sliding of the connecting block 31 can be ensured. A chute matching the size of the limiting rod 3 is formed inside the connecting block 31. The shape of the support arm 32 is set as "冖", which can give a stable supporting force to the calibration mechanism 4 and prevent problems with the calibration mechanism 4 itself during the measurement and calibration of the tool.

[0020] In an embodiment of the present invention, a calibration mechanism 4 is arranged on the upper surface of the support arm 32. The calibration mechanism 4 includes a dynamometer 41. The bottom surface of the dynamometer 41 is fixedly connected to the upper surface of the support arm 32. The movable end of the dynamometer 41 is fixedly connected to an equipment frame 42. The inner side wall of the equipment frame 42 is rotatably connected to a fixed shaft 43. A limiting wheel 44 is fixedly connected to the outer surface of the fixed shaft 43. A calibration block 45 is fixedly connected to the outer surface of the fixed shaft 43. One end of a clamping block 46 is clamped to the end of the fixed shaft 43, and the other end of the clamping block 46 is hinged to the side wall of the equipment frame 42. The limiting wheel 44 and the calibration block 45 are symmetrically distributed in a mirror image on the outer surface of the fixed shaft 43. The shape of the calibration block 45 is set as an arc. A limiting groove matching the size of the clamping block 46 is formed at the end of the fixed shaft 43. The sizes of the limiting wheel 44, the fixed shaft 43 and the calibration block 45 match the inner size of the equipment frame 42. The dynamometer 41 has two states. One is the force measurement mode. In this mode, the dynamometer 41 can accurately record the yaw problem and yaw amount existing on the outer surface of the tool. In the other mode, the dynamometer 41 can give a stable output force to the output end of the dynamometer 41 and apply the accurately recorded yaw amount to the outer surface of the tool. The force applied by the dynamometer 41 is the same as the force recorded by the yaw measurement of the dynamometer 41, further ensuring that no additional damage is caused to the tool itself. Through the clamping block 46 and the limiting groove, the relative position of the fixed shaft 43 can be restricted. When the clamping block 46 is in the limiting groove, the fixed shaft 43 is firmly fixed and will not rotate. The fixed fixed shaft 43 can measure or calibrate the tool through the limiting wheel 44 and the calibration block 45. By opening the clamping block 46, the limiting wheel 44 and the calibration block 45 can be switched.

[0021] In this invention, during use, the tool is placed in the equipment slot 21, and then the movable frame 27 is rotated to fix the tool. The position of the movable frame 27 is fixed by the attraction of the magnet 25. At this time, the slide rod 210 drives the tool to move down under the pressure of the telescopic spring 29, so that the tool contacts and presses on the pulley 23. Then, the connecting block 31 is slid along the limit rod 3 to adjust the position of the support arm 32 and the entire correction mechanism 4. The motor 212 can drive the roller 213 to rotate, further driving the tool to rotate, so that the limit wheel 44 of the correction block 45 abuts against the outer wall of the tool. The force applied by the tool sway is observed by the force gauge 41. When the force gauge 41 shows an abnormal force value (i.e., there is sway), the fixed shaft 43 is manually rotated, and the arc surface of the correction block 45 is used to accurately tap the abnormal point of the tool until the force value displayed by the force gauge 41 is stable within the normal range, thus completing the sway correction.

[0022] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
