Description

Technical Field

[0001] This utility model relates to the field of milling machine technology, specifically to a precision milling machine. Background Technology

[0002] A milling machine is a machine tool that uses a milling cutter to machine various surfaces of a workpiece. Typically, the rotation of the milling cutter is the primary motion, while the movement of the workpiece and the milling cutter constitutes the feed motion. It can machine planes, grooves, various curved surfaces, and gears.

[0003] During milling, coolant (cutting fluid) is used to reduce cutting temperature, lubricate the cutting tool, and flush away chips. Because a large amount of metal debris is generated during machining, the coolant mixes with the debris, necessitating a filtration system to purify the coolant. In the coolant filtration system of the milling machine table, filter plates are typically bolted to the bottom of the table. However, each time the filter plates are cleaned or the filter screen is replaced, the bolts must be removed one by one, which is time-consuming and labor-intensive. Utility Model Content

[0010] Preferably, the collection section also has a groove inside the connecting frame, the filter plate is embedded in the groove and slidably connected to the connecting frame, and a metal filter screen is provided inside the filter plate.

[0011] By adopting the above technical solution, the filter plate can be pulled horizontally through the sliding groove, which facilitates the cleaning of metal debris. At the same time, the metal filter screen can filter impurities in the coolant, realizing the recycling of coolant.

[0012] Preferably, the collection section also has a rotating groove opened at the outward end of the filter plate, and the rotating frame is embedded in the rotating groove and rotatably connected to the connecting frame.

[0017] By adopting the above technical solution, the limiting slot and the chamfered limiting post can be used to reduce the frictional resistance during engagement, making the fixing and releasing operation of the rotating frame smoother.

[0018] Preferably, there are two limiting slots, and the two limiting slots are arranged in a central rotation structure around the rotation center of the rotating frame.

[0019] By adopting the above technical solution, the stability of the rotating frame can be improved by the engagement of the symmetrically distributed limiting slots with the two limiting pins.

[0020] Preferably, the connecting frame is provided with a guide ramp b inside, and the bottom of the guide ramp b is provided with a drain port.

A limiting frame 206 is provided on the side of the connecting frame 201. A limiting pin 207 is slidably provided inside the limiting frame 206. The limiting pin 207 is engaged with the rotating frame 205 to fix the position of the connecting frame 201. The debris and coolant generated during processing can be guided into the collection part 2 by the guide ramp a104. The debris separation and rapid cleaning are achieved by the sliding of the filter plate 203 and the engaging structure of the rotating frame 205. At the same time, the limiting frame 206 and the limiting pin 207 ensure the stable fixation of the collection part 2.

[0034] Example 2

[0035] Please see Figure 4 , Figure 5 and Figure 6 This embodiment provides a technical solution: a precision milling machine, including a collecting part 2, a rotating frame 205, and a limiting frame 206.

[0036] The frame 1 also has a robotic arm 102 mounted on top of the frame 1. The robotic arm 102 is equipped with a milling cutter 103 with a power source. The robotic arm 102 can drive the milling cutter 103 to perform multi-angle precision machining, thereby improving machining flexibility and accuracy.

[0037] A sliding groove 202 is provided inside the connecting frame 201. The filter plate 203 is embedded in the sliding groove 202 and is slidably connected to the connecting frame 201. A metal filter screen is provided inside the filter plate 203. The filter plate 203 can be pulled out laterally through the sliding groove 202 to facilitate the cleaning of metal debris. At the same time, the metal filter screen can filter impurities in the coolant and realize the recycling of coolant.

[0038] A rotating groove 204 is provided at the outward end of the filter plate 203. The rotating frame 205 is embedded in the rotating groove 204 and rotatably connected to the connecting frame 201. The rotating frame 205 can be rotated in the rotating groove 204 to adjust the rotation angle of the rotating frame 205 so as to lock into the limiting frame 206 and fix the position of the rotating frame 205.

[0039] The limiting frame 206 has two limiting pins 207 slidably embedded inside. One end of the limiting pin 207 is provided with a spring 208. The spring 208 is located between the limiting frame 206 and the limiting pin 207. The spring 208 can push the limiting pin 207 to automatically reset through the elastic force of the spring 208, ensuring the firm engagement of the limiting pin 207 and the rotating frame 205 and preventing loosening caused by processing vibration.

[0040] A limiting slot 209 is provided on the side of the rotating frame 205. The limiting slot 209 engages with the limiting post 207. The part of the limiting post 207 that abuts against the limiting slot 209 is chamfered. The engagement of the limiting slot 209 and the chamfered limiting post 207 can reduce the frictional resistance during engagement, making the fixing and releasing operation of the rotating frame 205 smoother.

[0041] Two limiting slots 209 are provided, and the two limiting slots 209 form a central rotation structure around the rotation center of the rotating frame 205. The stability of the rotating frame 205 is improved by engaging the symmetrically distributed limiting slots 209 with the two limiting posts 207.

[0042] Inside the connecting frame 201, there is a guide ramp b210, and at the bottom of the guide ramp b210 is a drain port 211. The filtered coolant can be guided by the guide ramp b210 to flow to the drain port 211 for easy recycling or discharge, and to avoid liquid stagnation that could lead to corrosion or pollution.

[0043] Working principle: First, metal chips and coolant generated during processing are splashed onto the surface of the worktable 101 by the milling cutter 103 and slide along the guide ramp a104 into the connecting frame 201 of the collection section 2. The chips are intercepted by the metal filter screen of the filter plate 203, while the coolant flows through the filter screen into the guide ramp b210 and is finally discharged or recycled through the drain port 211. When it is necessary to clean the chips, the operator rotates the rotating frame 205, causing the limiting slot 209 to slide out from the limiting pin 207, thereby allowing the chips to be removed. The filter plate 203 is pulled out, and the accumulated debris is poured into an external container. After cleaning, the filter plate 203 is slid into the slide groove 202. Then, the rotating frame 205 is rotated so that both ends of the rotating frame 205 move into the limiting frame 206. The limiting pins 207 are pushed into the limiting slots 209 by the spring 208 to fix the position of the rotating frame 205. The symmetrically distributed limiting slots 209 and the double limiting pins 207 structure enhance the stability of the rotating frame 205 and prevent loosening caused by processing vibration.
