Description

Technical Field

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

[0002] A vertical milling machine is a metal cutting machine tool with a vertically arranged spindle. It uses a high-speed rotating milling cutter to machine planes, grooves, gears, holes, and complex curved surfaces on workpieces. Its structure includes a height-adjustable spindle head and a horizontally movable worktable, supporting multi-axis linkage to achieve three-dimensional machining. It combines rigid cutting capabilities with tool adaptability and is widely used in mechanical manufacturing, mold processing, and small-batch production. CNC models can achieve high-precision automated operation. When machining workpieces on a milling machine, they need to be clamped and fixed, which requires the use of workpiece fixtures.

[0003] An investigation revealed that patent CN109174573A discloses a small workpiece fixture, including a base for accommodating the workpiece, and a clamping device disposed on one side of the base for fixing the workpiece. The base has a groove for accommodating the bottom of the workpiece. The clamping device includes two clamping arms that abut against the outer wall of the workpiece, each abutting against opposite sides of the workpiece. By using the two clamping arms to abut against opposite sides of the workpiece to fix the upper part, and then placing the workpiece into the groove to fix the lower part, the workpiece is effectively constrained, preventing it from shaking or shifting during processing.

[0004] However, most workpiece fixtures on the market today have a relatively simple structure. Frequent clamping of the clamping parts can lead to wear and tear. Most fixtures cannot replace the clamping components, which reduces the service life of the workpiece fixture, increases the cost of using the workpiece fixture, and is not conducive to the long-term use of the workpiece fixture. Utility Model Content

This allows the workpiece fixture to have a more varied structure, enabling quick replacement of the clamping components when they wear out, thereby extending the overall service life of the fixture, reducing the cost of using the fixture, and facilitating its long-term use.

[0008] Preferably, an external plate is fixedly connected to one side of the clamping frame, and an upright plate is fixedly connected to one side of the external plate.

[0012] Preferably, one side of the movable block is movably connected to the outer wall of the limiting post, and the length of the limiting post is equal to the length of the rotating threaded post.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 As shown, a workpiece fixture includes a clamping frame 1. A side motor 2 is fixedly connected to one side of the clamping frame 1. The output shaft of the side motor 2 is fixedly connected to a rotating threaded column 3 via a coupling. A movable block 4 is movably connected to the outer wall of the rotating threaded column 3. A limit post 5 is movably connected to one side of the movable block 4. An external connecting block 6 is fixedly connected to one side of the movable block 4. An insertion frame 7 is fixedly connected to one side of the external connecting block 6.

[0025] A locking arc block 8 is movably connected to one side of the interlocking frame 7. An inner spring 9 is fixedly connected to one side of the interlocking arc block 8. An interlocking block 10 is fixedly connected to one end of the inner spring 9. A clamping plate 11 is fixedly connected to one side of the interlocking block 10. An intermediate plate 12 is fixedly connected to one end of the limiting post 5. A partition plate 13 is fixedly connected to one side of the intermediate plate 12. This allows the workpiece fixture to have a more complex structure. When the clamping parts wear out, the clamping parts of the fixture can be quickly replaced, thereby improving the overall service life of the fixture, reducing the cost of using the fixture, and facilitating the long-term use of the workpiece fixture.

[0026] An external plate 14 is fixedly connected to one side of the clamping frame 1, and a vertical plate 15 is fixedly connected to one side of the external plate 14 for easy connection with other components. A short plate 16 is fixedly connected to the bottom of the vertical plate 15, and the length of the short plate 16 is less than the length of the external plate 14. A rotating threaded bolt 17 is movably connected to the bottom of the external plate 14. A bearing 18 is fixedly connected to the outer wall of the rotating threaded bolt 17, and a pressing plate 19 is fixedly connected to the outer wall of the bearing 18. A gripping plate 20 is fixedly connected to one end of the rotating threaded bolt 17 to lock the position of the clamp.

[0027] The coupling of the side motor 2 passes through the clamping frame 1 and is fixedly connected to one end of the rotating threaded column 3. There are two side motors 2 and two rotating threaded columns 3, which allows the fixture to quickly and automatically clamp the workpiece. One side of the movable block 4 is movably connected to the outer wall of the limiting column 5, and the length of the limiting column 5 is equal to the length of the rotating threaded column 3, which allows the movable block 4 to move in a stable linear motion. One side of the partition plate 13 is fixedly connected to one side of the intermediate plate 12, and the other side of the partition plate 13 is fixedly connected to the inside of the clamping frame 1. The length of the partition plate 13 is equal to the internal length of the clamping frame 1, which avoids the clamped workpiece from affecting the rotation of the rotating threaded column 3.

[0028] Working principle: Move the entire fixture to the side of the milling machine. By rotating the gripping plate 20, the threaded bolt 17 rotates, allowing the pressing plate 19 to clamp the milling machine with the outer plate 14. If the clamping parts need to be replaced, press the locking arc block 8 to compress the inner spring 9, thereby causing the locking arc block 8 to retract to the insertion block 10. Align the insertion block 10 of the clamping plate 11 to be replaced with the insertion frame 7 on the outer block 6 and insert it, thereby making the insertion block 10 and the insertion frame 7 engage. If it is necessary to clamp the workpiece, place the workpiece to be clamped between the two clamping plates 11. The side motor 2 works, and the output shaft of the side motor 2 rotates, causing the rotating threaded column 3 to rotate. The rotation of the rotating threaded column 3 causes the movable block 4 to drive the clamping plate 11 to clamp the workpiece, thereby completing the clamping and locking of the workpiece.
