Description

Technical Field

[0002] As we all know, CNC machine tools are widely used in precision machining applications and can produce various complex-shaped workpieces. Therefore, CNC machine tools are increasingly favored by enterprises.

[0003] In the CNC machining process of electric needles, the electric needle is clamped on a fixture with the machined end facing upwards. A milling cutter mounted on the spindle performs a cross-reciprocating horizontal motion to machine a milled pattern on the electric needle, that is, to machine multiple small pyramids arranged in a specified pattern at the end of the electric needle. However, in the existing milling equipment, after machining one electric needle, it is necessary to immediately replace it with another electric needle to be machined. This method increases the downtime of the milling equipment and cannot guarantee the machining efficiency. In addition, the existing milling equipment also has the disadvantage of being difficult to clamp, which is not conducive to the operation of the operator. Therefore, there is an urgent need for a precision milling equipment to overcome the above-mentioned defects. Utility Model Content

[0026] Example

[0027] To address the issues of long downtime and complex clamping in existing milling equipment for current needle milling, this paper refers to... Figure 1 and Figure 2 As shown, in some embodiments, this application discloses a precision milling device, including: a machine tool 10;

[0028] The clamping mechanism 20 includes an XY-axis moving platform 21 mounted on the machine tool 10, a frame 22 connected to the XY-axis moving platform 21, and a fixture unit 23 mounted on the table of the frame 22 for synchronously clamping multiple products. In actual use, the operator places multiple current needles in the fixture unit 23 and clamps them synchronously through the fixture unit 23. During the specific processing, the XY-axis moving platform 21 drives the frame 22 and the fixture unit 23 above it to move along the X-axis and Y-axis in real time.

[0029] The milling mechanism 30 includes a stand 31 mounted on the machine tool 10, a Z-axis moving platform 32 mounted on the stand 31 facing the XY-axis moving platform 21, a power unit 33 mounted on the Z-axis moving platform 32, and a precision milling cutter 34 connected to the power unit 33. When milling the current needle held by the fixture unit 23, the Z-axis moving platform 32 drives the power unit 33 to move along the Z-axis direction, and the precision milling cutter 34 can perform milling on each needle one by one.

[0030] Based on the above structure, operators are spared from repeatedly clamping the current needle, which improves work efficiency, reduces the difficulty of operation, and has high practicality.

[0031] In one exemplary embodiment, the XY-axis moving platform 21 of this application includes an X-axis precision lead screw module 211, a Y-axis precision lead screw module 212, and a first platform 213. The X-axis precision lead screw module 211 is mounted on the machine tool, the Y-axis precision lead screw module 212 is connected to the X-axis precision lead screw module 211, and the first platform 213 is connected to the Y-axis precision lead screw module 212. The frame 22 is fixedly mounted on the first platform 213. In a specific implementation, driven by the X-axis precision lead screw module 211, the Y-axis precision lead screw module 212 moves along the X-axis direction, and driven by the Y-axis precision lead screw module 212, the first platform 213 moves along the Y-axis direction. Since the frame 22 and the fixture unit 23 are mounted on the first platform 213, the frame 22 and the fixture unit 23 will also move synchronously along the X-axis and Y-axis.

[0032] In one exemplary embodiment, the clamping unit 23 of this application includes a carrier plate 231, a telescopic pushing unit 232, a pushing block 233, two first rollers 234, two second rollers 235, and two clamping plates 236. The carrier plate 231 is fixed on the table surface of the frame 22. The pushing block 233 is slidably disposed on one side of the carrier plate 231. The telescopic pushing unit 232 is disposed on the carrier plate 231 corresponding to one side of the pushing block 233. The two clamping plates 236 are respectively slidably disposed on the carrier plate 231 corresponding to the other side of the pushing block 233 and form a T-shaped structure. The two clamping plates 236 are provided with a plurality of clamping grooves 236c for clamping products in a straight line. The two clamping plates 236 are respectively provided with a first inclined edge 236a on the side away from the pushing block 233. The two first rollers 234 are respectively disposed on the carrier plate 231 in contact with the two first inclined edges 236a. The clamping plate 236 has a second inclined edge 236b on one side near the push block 233. Two second rollers 235 are respectively positioned on the carrier plate 231, contacting the two second inclined edges 236b. The carrier plate 231 and the table surface of the frame 22 are provided with several clearance grooves 237 corresponding to the clamping grooves 236c in a straight line. During the clamping of multiple current needles, the operator inserts the multiple current needles with their heads facing upwards and their rods facing upwards into the clamping grooves 236c, and finally ensures that the rods pass through the corresponding clearance grooves 237 and the heads are located in the clamping grooves 236c. After that, the telescopic push unit 232 is controlled to drive the push block 233 to move. During this process, the first inclined edge 236a and the second inclined edge 236b of the two clamping plates 236 will cooperate with the first roller 234 and the second roller 235 respectively to bring them closer to each other, thereby clamping the heads of each current needle.

[0033] In a preferred embodiment, the telescopic pushing unit 232 of this application includes a servo motor 2321 and an eccentric wheel 2322. The servo motor 2321 is located below one side of the platform of the frame 22 and its output shaft passes through the carrier plate 231 and is connected to the eccentric wheel 2322. The eccentric wheel 2322 is located on one side of the pushing block 233 and pushes the block 233 to move under the drive of the servo motor 2321. When the servo motor 2321 drives the eccentric wheel 2322 to rotate, the eccentric wheel 2322 can control the telescopic extension and retraction of the pushing block 233.

[0034] Based on the above embodiments, in order to enable the push block 233 to slide, the present application provides a first slide groove 2311 on one side of the carrier plate 231, and a first slider 2331 is provided at the bottom of the push block 233 and slides inside the first slide groove 2311. When the servo motor 2321 drives the eccentric wheel 2322 to rotate, the first slider 2331 will slide in the first slide groove 2311.

[0035] In addition, the two clamping plates 236 of this application are respectively provided with second sliding grooves 2361 on the side near the pushing block 233, and the pushing block 233 is provided with second sliders 2332 on the side near the two clamping plates 236, which slide in the two second sliding grooves 2361.

[0036] When the servo motor 2321 drives the eccentric wheel 2322 to rotate, the push block 233 pushes the two clamping plates 236 to move closer to each other. At this time, through the cooperation of the second slider 2332 and the second slide groove 2361, the two clamping plates 236 can stably clamp several current needles.

[0037] In one exemplary embodiment, the Z-axis moving platform 32 includes a Z-axis precision lead screw module 321 and a second platform 322. The Z-axis precision lead screw module 321 is mounted on the stand 31 facing the XY-axis moving platform 21. The second platform 322 is connected to the Z-axis precision lead screw module 321. The power unit 33 is fixed on the second platform 322. Driven by the Z-axis precision lead screw module 321, the power unit 33 will realize Z-axis movement. Since the precision milling cutter 34 is mounted on the power unit 33, the precision milling cutter 34 can realize Z-axis lifting and lowering.

[0038] Based on the above embodiments, the power unit 33 of this application includes a power motor 331 and a milling cutter holder 332. The milling cutter holder 332 is disposed on the second platform 322, and the power motor 331 is connected and disposed above the milling cutter holder 332. The precision milling cutter 34 is mounted on the milling cutter holder 332. With the cooperation of the power motor 331 and the milling cutter holder 332, the precision milling cutter 34 of this application can rotate, and thus can perform milling on the head of the current needle in reciprocating motion.
