It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] Please see Figures 1 to 5 The present invention provides a tooling for a CNC milling machine, comprising: a machine body 1, a spindle 2 mounted on the upper end of the machine body 1, a movable table 3 mounted on the upper surface of the machine body 1, an adjustment structure 4 provided on the upper surface of the movable table 3, and an auxiliary structure 5 provided on the upper surface of the base plate 401.

[0032] In the embodiments of this utility model, please refer to Figures 2 to 4The adjustment structure 4 includes a base plate 401, which is fixedly connected to the movable platform 3. A cover frame 402 is fixedly connected to the upper surface of the base plate 401. Two support frames 403 are fixedly connected to the upper surface of the base plate 401. Two movable frames 404 are slidably connected to the arc surfaces of the two support frames 403. A connecting rod 405 is rotatably connected to the inner wall of each of the two movable frames 404. A movable block 406 is rotatably connected to one end of each connecting rod 405 that is close to the other. A fixed frame 407 is fixedly connected to the upper surface of the base plate 401. The fixed frame 407 is slidably connected to the movable block 406. A round rod 408 is rotatably connected to the inner wall of the fixed frame 407. The arc surface of the round rod 408 is threadedly connected to the movable block 406. A servo motor 409 is fixedly connected to the upper surface of the base plate 401. The output end of the servo motor 409 is fixedly connected to the round rod 408. Adjusting rods 410 are screwed into the surfaces of the two movable frames 404. The two adjusting rods 410 are rotatably connected to the one end that is close to the other. A clamping plate 411 is connected to the adjusting rod 410. A limiting plate 412 is fixedly connected to the side of the clamping plate 411 near the adjusting rod 410. The limiting plate 412 is slidably connected to the moving frame 404. The moving frame 404 is driven to move synchronously by a servo motor 409. The workpiece is clamped and limited by the two clamping plates 411, and the clamping is stable and can clamp workpieces of different sizes. Several anti-slip protrusions are fixedly connected to the end of the adjusting rod 410 away from the clamping plate 411. The anti-slip protrusions are evenly distributed on the adjusting rod. On the rod 410, anti-slip protrusions increase the friction of the operating end of the adjusting rod 410, making it easier for the user to rotate the adjusting rod 410. A scale 413 is provided on one side of the limiting plate 412. By referring to the scale 413, the user can intuitively judge the distance between the clamping plate 411 and the moving frame 404. Several anti-slip patterns are provided on the side of the clamping plate 411 away from the adjusting rod 410. The anti-slip patterns increase the friction of the surface of the clamping plate 411, making the clamping plate 411 better at limiting the workpiece.

[0033] In the embodiments of this utility model, please refer to Figure 5 The auxiliary structure 5 includes a mounting frame 51, which is fixedly connected to the base plate 401. A storage frame 52 is slidably connected to the inner wall of the mounting frame 51. The four sides of the storage frame 52 are slidably connected to the cover frame 402. Two sliding rods 55 are slidably connected to both sides of the inner wall of the mounting frame 51. A positioning plate 54 is fixedly connected to the end of each sliding rod 55 that is close to each other. A spring 56 is sleeved on the arc surface of the sliding rod 55. The two ends of the spring 56 are fixedly connected to the positioning plate 54 and the mounting frame 51, respectively. The easily detachable storage frame 52 collects the processing debris, making it convenient for users to manage the debris and keep the upper surface of the cover frame 402 clean. The upper ends of the two positioning plates 54 are arc-shaped, making it convenient for the storage frame 52 to push the two positioning plates 54 away from each other along the arc surface of the positioning plates 54. The inner walls of the storage frame 52 are fixedly connected to handles 53 on both sides. The cross section of the handles 53 is "U"-shaped. Operating the handles 53 drives the storage frame 52 to move, making it convenient for users to move the storage frame 52.

[0034] The working principle of the CNC milling machine fixture provided by this utility model is as follows: By setting the adjustment structure 4, the workpiece is first placed on the cover frame 402 and positioned between the two clamping plates 411. The servo motor 409 is started, and the servo motor 409 drives the round rod 408 to rotate along the fixed frame 407. During this process, the round rod 408 drives the moving block 406 to move along the fixed frame towards the servo motor 409 via the thread. The moving block 406 then drives the two connecting rods 405 to rotate. During the rotation of the two connecting rods 405, they respectively drive the two moving frames 404 to move towards each other. The two moving frames 404 always slide along the arc surface of the support frame 403. The servo motor 409 continues to rotate, and the moving frames 404 drive the clamping plates 411 to move via the adjustment rod 410 until the two clamping plates 411 move the workpiece. The workpiece is clamped and limited on the cover frame 402. When processing non-standard or irregularly shaped parts, first rotate the adjusting rod 410. The adjusting rod 410 moves laterally along the moving frame 404 by means of the thread. The adjusting rod 410 drives the clamping plate 411 to move closer to or away from the moving frame 404. The clamping plate 411 drives the limiting plate 412 to slide along the moving frame 404. According to the processing requirements, the distance between the clamping plate 411 and the moving frame 404 is changed, thereby changing the position of the workpiece relative to the center of the base plate 401 when it is clamped. Among them, the friction of the operating end of the adjusting rod 410 is increased by the anti-slip protrusions, which makes it convenient for the user to rotate the adjusting rod 410. Referring to the scale 413, the user can intuitively judge the distance between the clamping plate 411 and the moving frame 404. The friction of the surface of the clamping plate 411 is increased by the anti-slip texture, which makes the clamping plate 411 better at limiting the workpiece.

[0035] By setting the auxiliary structure 5, the storage frame 52 is moved from top to bottom into the cover frame 402. The storage frame 52 moves along the cover frame 402 towards the mounting frame 51. When the lower end of the storage frame 52 abuts against the two positioning plates 54 of the mounting frame 51, the storage frame 52 continues to move downward along the inclined surface of the positioning plates 54. Under the action of force, the two positioning plates 54 move away from each other. The positioning plates 54 drive the slide bar 55 to move along the mounting frame 51. The spring 56 is in a compressed state. Then the storage frame 52 continues to move downward until the storage frame 52 is fully moved into the cover frame 402 and the mounting frame 51. Under the action of the spring 56, the positioning plates 54 continue to abut against the storage frame 52. This allows the storage frame 52 to push the two positioning plates 54 away from each other along the arc surface of the positioning plates 54. The operating handle 53 drives the storage frame 52 to move, making it convenient for the user to move the storage frame 52.

[0036] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
