Description

Technical Field

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

[0002] Milling is a cutting process where the rotation of the milling cutter is the primary motion, and the cutter or workpiece serves as the feed motion. Milling offers high production efficiency and a wide processing range. On a standard milling machine, various milling cutters can be used to machine planes (parallel, vertical, and inclined planes), steps, grooves (right-angle grooves, V-grooves, T-grooves, dovetail grooves, and other special-shaped grooves), and other special-shaped surfaces. With the assistance of milling machine accessories such as indexing heads, it is also possible to mill splined shafts, helical shafts, and gear clutches. Since the planes of milled workpieces are often irregularly shaped, they typically require various sizes of fixtures that can be fixed to the worktable for secure machining, making the overall fixing process quite cumbersome.

[0003] When using existing milling machines, operators generally need to fix the fixture to the worktable with bolts, which is not only time-consuming and labor-intensive, but also troublesome to install. In addition, when milling thinner workpieces, the workpiece can only be fixed in one direction, which can easily cause it to deform and thus affect the accuracy of the milled products. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The purpose of this utility model is to provide a milling machine processing device to solve the above-mentioned problems, so as to solve the problems of the cumbersome installation of the bolt-fixed fixture in the prior art, and the fact that when processing thinner workpieces, it can only be fixed in one direction, which can easily cause deformation and affect the product accuracy.

A locking block is fixedly connected to the bottom surface of each slider. Two symmetrical locking strips are fixedly connected to the upper surface of the worktable. The outer surface of the locking block engages with the locking strips. The fixing mechanism can fix the clamp to the worktable, avoiding the need to fix it by tightening bolts, saving time and effort, and making installation convenient.

[0010] The clamping mechanism includes a motor, the output end of which is fixedly connected to a rotating rod.

This mechanism can clamp and fix the workpiece in both horizontal and vertical directions, avoiding deformation caused by unstable clamping when milling thin workpieces, and improving the accuracy of milled products.

[0011] Preferably, the ends of the two fixing blocks that are close to each other are fixedly connected to the outer surface of the clamp.

[0028] This utility model provides a milling machine milling apparatus.

[0029] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 It includes a workbench 1, a clamp 2 is provided above the workbench 1, and a fixing mechanism 3 is provided between the workbench 1 and the clamp 2;

[0030] Please refer to this carefully. Figure 1 , Figure 2 and Figure 4The fixing mechanism 3 includes two fixing blocks 301. Each fixing block 301 has a groove 302 inside. Each groove 302 has a slider 303 slidably connected inside. The ends of the two sliders 303 that are close to each other are fixedly connected to springs 304. The ends of the two springs 304 that are close to each other are fixedly connected to the outer surface of the clamp 2. The bottom surfaces of the two sliders 303 are fixedly connected to locking blocks 305. The upper surface of the worktable 1 is fixedly connected to two symmetrical locking strips 306. The outer surface of the locking block 305 is engaged with the locking strip 306.

[0031] The ends of the two fixed blocks 301 that are close to each other are fixedly connected to the outer surface of the clamp 2. Pushing the two sliders 303 towards the middle can cause the two locking blocks 305 to move closer to each other. When the clamp 2 is slid to the appropriate position, the two locking blocks 305 are released. Under the action of the spring 304, the sliders 303 can drive the locking blocks 305 to slide outward along the slide groove 302, so that the two locking blocks 305 can engage with the locking strip 306, thereby fixing the clamp 2 on the worktable 1. This avoids fixing it by tightening bolts, saving time and effort and making installation convenient.

[0032] Please refer to this carefully. Figure 1 and Figure 3 The clamp 2 is equipped with a clamping mechanism 4, which includes a motor 401. The output end of the motor 401 is fixedly connected to a rotating rod 402. The outer surface of the rotating rod 402 is provided with two opposite threads. The outer surface of the rotating rod 402 is threadedly connected to two symmetrical sliding plates 403. The upper surface of each sliding plate 403 is fixedly connected to a first clamping block 404. The interior of each first clamping block 404 is threadedly connected to a screw 405. The bottom end of each screw 405 is fixedly connected to a second clamping block 406.

[0033] The fixture 2 has a mechanism slot 408 inside. The outer surface of the rotating rod 402 is rotatably connected to the inner wall of the mechanism slot 408, and the outer surface of the motor 401 is fixedly connected to the outer surface of the fixture 2.

[0034] A screw block 407 is fixedly connected to the top of the screw 405. Guide rods 409 are fixedly connected to the outer surface of the first clamping block 404, and the outer surface of the guide rods 409 is slidably connected to the second clamping block 406. Activating the motor 401 in the clamping mechanism 4 causes the rotating rod 402 to rotate, thereby causing the two sliding plates 403 to move the two first clamping blocks 404 closer together or further apart, thus fixing the workpiece horizontally. Tightening the screw block 407 causes the second clamping block 406 to slide along the guide rods 409, thereby fixing the workpiece vertically. This prevents deformation of thinner workpieces due to unstable clamping during milling, improving the accuracy of milled products.

[0035] Please refer to this carefully. Figure 1 and Figure 2 The bottom surface of the workbench 1 is provided with a moving mechanism 5. The moving mechanism 5 includes a base plate 501. The upper surface of the base plate 501 is rotatably connected to a screw 502 through a set of fixed plates. The outer surface of the screw 502 is threadedly connected to the workbench 1 through a support plate. A set of protrusions 503 are fixedly connected to the upper surface of the base plate 501. The outer surface of each protrusion 503 is slidably connected to a slide bar 504 that is adapted to the protrusion 503. The upper surface of the slide bar 504 is fixedly connected to the bottom surface of the workbench 1.

[0036] One end of the second screw 502 is fixedly connected to a rocker arm 505. Rotating the rocker arm 505 in the moving mechanism 5 causes the second screw 502 to rotate, which in turn drives the worktable 1 to slide along the protrusion 503 on the second screw 502 via the support plate. This enables the workpiece to move during milling, thereby improving the efficiency of milling.

[0037] In use, this utility model is as follows: First, place the clamp 2 on the workbench 1, push the two sliders 303 towards the center, which will cause the two locking blocks 305 to move closer together. When the clamp 2 is slid to the appropriate position, release the two locking blocks 305. Under the action of the spring 304, the sliders 303 can drive the locking blocks 305 to slide outward along the slide groove 302, thereby allowing the two locking blocks 305 to engage with the locking strip 306, thus fixing the clamp 2 on the workbench 1. This avoids fixing it by tightening bolts, saving time and effort, and making installation convenient. The workpiece is then placed on the fixture 2, and the motor 401 in the clamping mechanism 4 is started, which causes the rotating rod 402 to rotate. This causes the two sliding plates 403 to move the two first clamping blocks 404 closer to or further away from each other, thereby fixing the workpiece in the horizontal direction. Then, the screw block 407 is turned, which causes the second clamping block 406 to slide along the guide rod 409, thereby fixing the workpiece in the vertical direction. This avoids deformation of thinner workpieces due to unstable clamping during milling, and improves the accuracy of milled products.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
