Description

Technical Field

[0001] The utility model relates to the technical field of machine tool positioning, in particular to a three-axis NC flexible positioning tool. Background Art

[0002] Three-axis NC flexible positioning is a positioning system used in automation equipment and CNC machine tools, which allows high-precision and flexible motion control on three mutually perpendicular axes.

[0003] At present, the existing three-axis NC flexible positioning tooling can only perform clamping positioning when positioning the workpiece. During the processing, the workpiece is prone to problems such as loose fixation and position deviation, which in turn affects the processing accuracy.

[0004] To this end, we propose a three-axis NC flexible positioning tool that can fit the workpiece for fixation. Utility Model Content

[0005] In order to overcome the disadvantage that the existing three-axis NC flexible positioning tool relies on clamping for positioning and has unstable fixation, the utility model provides a three-axis NC flexible positioning tool that can fit the workpiece for fixation.

[0006] The three-axis NC flexible positioning tooling includes a main box, four long cylinders are fixedly connected to the bottom of the main box, the main box is fixedly connected to a transversely symmetrical plate frame, a transverse plate is slidably connected between the transversely symmetrical plate frames, long threaded rods are rotatably connected to the tops of the transversely symmetrical plate frames, the long threaded rods are threadedly connected to the transverse plate, a flat belt is connected between the transversely symmetrical long threaded rods through a pulley, a large motor is fixedly connected to the plate frame on one side, the output shaft of the large motor is connected to the adjacent long threaded rod, a block is slidably connected to the transverse plate, a short threaded rod is rotatably connected to the transverse plate, the short threaded rod is threadedly connected to the block, a small motor is fixedly connected to the transverse plate, the output shaft of the small motor is connected to the short threaded rod, a telescopic cylinder is fixedly connected to the block, equidistantly distributed telescopic positioning rods are fixedly connected in the main box, an air pump is fixedly connected to the bottom of the main box, and the air pump is connected to the telescopic positioning rod through an air pipe.

[0007] Furthermore, it also includes a transversely symmetrical support frame, which is fixedly connected to the main body box, and longitudinally symmetrical limiting wide plates are fixedly connected between the transversely symmetrical support frames. A plurality of longitudinally symmetrical support plates are fixedly connected in the main body box, and the longitudinally symmetrical support plates correspond to each other one by one. A rotating round rod is rotatably connected between the upper parts of the longitudinally corresponding support plates.

[0008] Furthermore, the side of the main box is provided with equidistantly distributed circular holes.

[0009] Furthermore, a rubber anti-sliding block is fixedly connected to the bottom end of the long cylinder.

[0010] Furthermore, the extended end of the telescopic cylinder is fixedly connected with a four-claw pressing block.

[0011] Furthermore, the top of the telescopic positioning rod is a suction cup structure.

[0012] The utility model has the following advantages: 1. The workpiece is placed on the telescopic positioning rod. The telescopic positioning rod can drive the suction cup to move up and down to fit the irregular shape of the adsorbed workpiece for fixation, and then the four-claw pressure block is controlled by the telescopic cylinder to move down and press on the workpiece for secondary fixation.

[0013] 2. When placing the workpiece on the telescopic positioning rod, the rotating round rod can make the workpiece move more convenient, and the limit width plate can block oversized workpieces to prevent the workpiece from being too large and unable to be effectively fixed by this device.

DETAILED DESCRIPTION

[0023] The preferred technical solution of the present utility model is described in detail below with reference to the accompanying drawings.

[0024] Example 1: Three-axis NC flexible positioning tooling, such as Figure 1-Figure 6 As shown, it includes a main box 1, a long cylinder 2, a plate frame 3, a horizontal plate 4, a long threaded rod 5, a flat belt 6, a large motor 7, a block 8, a short threaded rod 9, a small motor 10, a telescopic cylinder 11, a telescopic positioning rod 12 and an air pump 1201. The side of the main box 1 is provided with equidistantly distributed circular holes, four long cylinders 2 are fixedly connected to the lower side of the main box 1, and a rubber anti-sliding block is fixedly connected to the bottom end of the long cylinder 2. The left and right parts of the main box 1 are fixedly connected to the plate frame 3, and the horizontal plate 4 is slidably connected between the left and right plate frames 3. The upper sides of the left and right plate frames 3 are rotatably connected to the long threaded rod 5, the long threaded rod 5 is threadedly connected to the horizontal plate 4, and the front parts of the left and right long threaded rods 5 are connected to the flat belt 6 through a pulley. A large motor 7 is fixedly connected to the upper part of the plate frame 3 on the left, and the output shaft of the large motor 7 is connected to the long threaded rod 5 on the left. A block 8 is slidably connected to the horizontal plate 4, and a short threaded rod 9 is rotatably connected to the horizontal plate 4. The short threaded rod 9 is connected to the block 8 by threads. A small motor 10 is fixedly connected to the right part of the horizontal plate 4, and the output shaft of the small motor 10 is connected to the short threaded rod 9. A telescopic cylinder 11 is fixedly connected to the block 8, and a four-claw pressure block is fixedly connected to the extended end of the telescopic cylinder 11. Equidistantly distributed telescopic positioning rods 12 are fixedly connected in the main body box 1, and the top of the telescopic positioning rods 12 are all suction cup structures. An air pump 1201 is fixedly connected to the lower side of the main body box 1, and the air pump 1201 is connected to the telescopic positioning rod 12 through an air pipe.

[0025] When using this device, the staff puts the workpiece on the telescopic positioning rod 12. Since the telescopic positioning rod 12 can be extended and retracted, the telescopic positioning rod 12 can drive the suction cup to move up and down to fit the irregular shape of the workpiece. Then the staff uses the air pump 1201 to inhale air, so that the suction cup is adsorbed on the workpiece to fix the workpiece. Then the staff uses the large motor 7 and the long threaded rod 5 to drive the cross plate 4 to move forward and backward, and uses the small motor 10 and the short threaded rod 9 to drive the block 8 to slide left and right, and then adjust the position of the telescopic cylinder 11 and the four-claw pressure block. After adjustment, the telescopic cylinder 11 is used to control the four-claw pressure block to move down and press on the workpiece for secondary fixation. After the workpiece is fixed, the workpiece can be reinforced. During processing, it can be placed based on the circular hole opened on the side of the main box 1.

[0026] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 7 and Figure 8As shown, it also includes a limited width plate 13, a support frame 14, a support plate 15 and a rotating round rod 16. The support frames 14 are fixedly connected on both sides of the left and right sides of the main box 1, and a front-to-back symmetrical limited width plate 13 is fixedly connected between the left and right support frames 14. The front and rear parts of the main box 1 are fixedly connected with a plurality of support plates 15, and the support plates 15 on the front and rear sides correspond to each other. A rotating round rod 16 is rotatably connected between the upper parts of the two corresponding front and rear support plates 15.

[0027] When the workpiece is placed on the telescopic positioning rod 12, it is limited by the limiting wide plates 13 on the front and rear sides. If the width of the workpiece is greater than the two limiting wide plates 13, the workpiece cannot be placed inside the device and cannot be positioned and fixed. At the same time, when the workpiece is placed inside the device, the rotation of the rotating round rod 16 can make the movement of the workpiece more convenient.
