Description

Technical Field

[0001] This utility model relates to the technical field of machine tool machining origin correction device, specifically a machine tool machining origin correction device. Background Technology

[0002] The machine origin (Machine Zero Point) is the starting point of the machine tool coordinate system, also called the "machine origin" or "reference point". It is the benchmark for all coordinate calculations in the CNC control system. In the machining process of CNC machine tools, in order to ensure machining accuracy, it is usually necessary to locate the machine tool origin before machining to establish the correct coordinate system.

[0003] In practical use, sudden power outages, program interruptions, or other human errors often lead to the loss of machine tool origin information, thus affecting the accuracy of subsequent machining. Traditional origin repair methods mostly rely on system correction. However, in the event of a power outage, only physical repair can be used. The existing physical repair methods utilize positioning blocks. After the positioning blocks are clamped and fixed, the instability of the clamping device position and the low stability of the positioning blocks themselves can easily cause the device's calibrated point to shift, thus affecting the accuracy of origin repair.

[0004] Therefore, it is necessary to design a machine tool machining origin correction device to solve the above problems. Utility Model Content

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Please see Figure 1-3This utility model provides a machine tool machining origin correction device, including a base 1. The outer surface of the base 1 has two symmetrical clamping grooves 2 and a rotating groove 3. A rotating shaft 9 is rotatably connected inside the rotating groove 3. A rotating block 17 is fixedly sleeved on the outer surface of the rotating shaft 9. A positioning block 13 is fixedly connected to the top of the rotating block 17. A worm gear 8 is fixedly sleeved on the outer surface of the rotating shaft 9. A worm 10 is rotatably connected inside the base 1, and a connecting block 6 is fixedly connected to the outer surface of the base 1. A knob 7 is fixedly connected to one end of the worm 10. The worm gear 10 and worm wheel 8 mesh with each other. The positioning block 13 has a first groove 15 and a second groove 16 inside. An elastic post 14 is slidably inserted into the first groove 15.

A fixing block 4 is fixedly attached, and a laser pointer 5 is fixedly inserted into the outer surface of the fixing block 4. Multiple bases 1 are clamped together by the machine tool's clamping tool and fixed at the desired positioning position on the machine tool. The machine tool cutter presses against the elastic insert 14, and the pressing plate 20 elastically slides into the micro switch 21. The triggering of the micro switch 21 determines the XYZ axis position of the machine tool. Finally, in the event of a power outage and loss of origin, the elastic insert 14 on the multiple bases 1 is used to re-determine the machine tool's origin position. During clamping, to ensure positional accuracy, a level 12 is used. The level of the flexible insert 14 is determined by rotating the knob 7 to ensure the overall accuracy of the marking. At the same time, the laser pointer 5 is used to illuminate the marked point after the position is determined. The marked point is marked with a marker. When the position of the laser pointer 5 is off, the mark offset caused by the clamping offset is easily detected, which facilitates the adjustment of the position of the base 1. This ensures the overall accuracy of the marking of the device for the second time, which facilitates the contact between the tool and the flexible insert 14 to correct the origin position, thereby improving the efficiency of origin repair.

[0021] To facilitate the rotational connection of the worm gear 10 and thus adjust the rotation angle of the rotating block 17, thereby leveling the positioning block 13 when it is not placed on an uneven surface, one end of the worm gear 10 passes through the outside of the base 1 and the other end of the worm gear 10 passes through the outside of the connecting block 6, and the other end of the worm gear 10 is rotatably connected to the connecting block 6, and the knob 7 is fixed to the end of the worm gear 10 outside the connecting block 6.
