Abstract
Description
Technical Field
[0001] This utility model relates to the field of machining technology, specifically a customized anti-rotation cutting disc positioning device. Background Technology
[0002] In the field of machining, the cutting disc is an important machining component, and the stability of its clamping connection with the workpiece directly affects the cutting accuracy, operating efficiency and equipment life. At present, traditional cutting disc clamping devices have many problems in practical applications.
[0003] On the one hand, insufficient anti-rotation performance is a common pain point. Most devices are fixed by a single slot or bolt. Under high-speed cutting or when subjected to large cutting forces, the cutting disc and the workpiece are prone to relative rotation, which leads to increased machining errors and even causes safety hazards such as workpiece scrap and equipment damage. This relative rotation problem is more prominent in cutting irregular or high-strength materials, which seriously restricts the improvement of machining quality. On the other hand, it is difficult to balance ease of operation and connection stability. Some devices adopt complex multi-bolt fixing structures in pursuit of connection firmness. Although this can enhance stability to a certain extent, the loading and unloading process is cumbersome, requiring the use of various tools to repeatedly tighten the bolts, which greatly prolongs the workpiece changeover time and reduces production efficiency. On the other hand, some easy-to-operate clamping devices often have insufficient connection strength due to unreasonable structural design, and are prone to loosening during continuous operation, which cannot meet the requirements of long-term stable machining. Utility Model Content
[0004] The purpose of this invention is to provide a customized anti-rotation cutting disc positioning device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a customized anti-rotation cutting disc positioning device, comprising a cutting disc, a workpiece slidably connected to the inner wall of the cutting disc, three pick-and-place slots on the top of the cutting disc, a fixing block fixedly connected to the top of the cutting disc, a bolt on the top of the fixing block, an arc-shaped locking block fixedly connected to the inner wall of the cutting disc near the bottom, a limiting block fixedly connected to the inner wall of the cutting disc, a rectangular groove on the top of the cutting disc, a rotating shaft rotatably connected to the bottom of the inner wall of the rectangular groove, an eccentric locking block fixedly connected to the surface of the rotating shaft, a toggle block fixedly connected to the top of the eccentric locking block, a first arc-shaped locking groove corresponding to the arc-shaped locking block on the bottom of the workpiece, a second arc-shaped locking groove on the top of the workpiece, and a limiting groove corresponding to the limiting block on the bottom of the workpiece.
[0006] Preferably, there are three pick-and-place slots arranged in a circular array on the top of the cutting disk, and the pick-and-place slots extend to the bottom of the cutting disk.
[0007] Preferably, there are three sets of rectangular grooves, rotating shafts, eccentric locking blocks and actuating blocks, which are arranged in a circular array on the top of the cutting disc. The eccentric locking blocks are rotated by rotating the actuating blocks, so that the eccentric locking blocks rotate into the second arc-shaped locking groove of the groove.
[0008] Preferably, there are three arc-shaped blocks, which are fixedly connected to the inner wall of the cutting disc near the bottom in a circular array.
[0009] Preferably, there are three sets of the first arc-shaped slot and the second arc-shaped slot, which are respectively arranged in a circular array at the bottom and top of the workpiece being cut.
[0010] Preferably, both the limiting groove and the limiting block are triangular in shape, and the limiting block provides excellent stability within the limiting groove.
[0011] Preferably, the top of the fixing block has a hole with a diameter larger than that of the bolt. The fixing block is fixed to the workpiece by the bolt, thereby fixing the cutting disc.
[0012] Compared with the prior art, this utility model provides a customized anti-rotation cutting disc positioning device, which has the following beneficial effects:
[0013] 1. This customized anti-rotation cutting disc positioning device forms a multi-layered anti-rotation constraint structure through the cooperation of an arc-shaped locking block with a first arc-shaped locking groove, the engagement of an eccentric locking block with a second arc-shaped locking groove, and the fitting of a triangular limiting block with a limiting groove. This multi-dimensional limiting design significantly improves the connection rigidity between the cutting disc and the workpiece, effectively counteracting the rotational torque generated during cutting, preventing relative rotation between the two, and ensuring cutting accuracy and work quality. The triangular limiting block and limiting groove, utilizing the stability principle of triangles, provide extremely strong structural support for the connection between the cutting disc and the workpiece, reducing shaking and vibration during operation.
[0014] 2. This customized anti-rotation cutting disc positioning device features three pick-and-place slots on the top of the cutting disc, providing convenient operating space for picking up and placing workpieces, facilitating quick loading and unloading. Simultaneously, the locking and unlocking of the eccentric locking block can be controlled by rotating the actuating block. Operation is simple and intuitive, requiring no complex tools or procedures, significantly shortening workpiece changeover time and improving operational continuity and efficiency.

[0024] This utility model provides the following technical solution:
[0025] Example 1
[0026] Please see Figure 1-5 This utility model provides a technical solution: a customized anti-rotation cutting disc positioning device, including a cutting disc 101, a workpiece 102 slidably connected to the inner wall of the cutting disc 101, three pick-and-place slots 103 on the top of the cutting disc 101, a fixing block 104 fixedly connected to the top of the cutting disc 101, a bolt 105 on the top of the fixing block 104, an arc-shaped locking block 106 fixedly connected to the inner wall of the cutting disc 101 near the bottom, and a limit block 107 fixedly connected to the inner wall of the cutting disc 101. A rectangular groove 108 is provided on the top of the disc 101. A rotating shaft 109 is rotatably connected to the bottom of the inner wall of the rectangular groove 108. An eccentric locking block 1011 is fixedly connected to the surface of the rotating shaft 109. A toggle block 1012 is fixedly connected to the top of the eccentric locking block 1011. A first arc-shaped groove 1021 corresponding to the arc-shaped locking block 106 is provided at the bottom of the cutting workpiece 102. A second arc-shaped groove 1022 is provided at the top of the cutting workpiece 102. A limiting groove 1023 corresponding to the limiting block 107 is provided at the bottom of the cutting workpiece 102.
[0027] There are three pick-and-place slots 103, which are arranged in a circular array on the top of the cutting disk 101 and extend to the bottom of the cutting disk 101.
[0028] There are three sets of rectangular groove 108, rotating shaft 109, eccentric locking block 1011 and actuating block 1012, which are arranged in a circular array on the top of cutting disk 101. By rotating the actuating block 1012, the eccentric locking block 1011 is rotated, so that the eccentric locking block 1011 rotates into the second arc-shaped locking groove 1022.
[0029] There are three arc-shaped blocks 106, which are fixedly connected to the inner wall of the cutting disk 101 near the bottom in a circular array.
[0030] There are three sets of the first arc-shaped slot 1021 and the second arc-shaped slot 1022, which are respectively arranged in a circular array at the bottom and top of the workpiece 102 being cut.
[0031] Both the limiting groove 1023 and the limiting block 107 are triangular in shape. The limiting block 107 provides strong stability within the limiting groove 1023.
[0032] The top of the fixing block 104 has a hole with a diameter larger than that of the bolt 105. The fixing block 104 is fixed to the cutting workpiece by the bolt 105, thereby fixing the cutting disc 101.
[0033] In actual operation, when this device is used, during the installation of the cutting workpiece 102, the cutting workpiece 102 is inserted from the top of the cutting disc 101 by utilizing the sliding connection between the inner wall of the cutting disc 101 and the cutting workpiece 102. The cutting workpiece 102 then slides downwards along the inner wall of the cutting disc 101. During this process, the first arc-shaped groove 1021 at the bottom of the cutting workpiece 102 gradually aligns with and engages with the arc-shaped locking block 106 near the bottom of the inner wall of the cutting disc 101. Simultaneously, the triangular limiting groove 1023 at the bottom of the cutting workpiece 102 corresponds to and engages with the triangular limiting block 107 on the inner wall of the cutting disc 101. This step initially achieves the connection between the cutting workpiece 102 and the cutting disc 101. The radial positioning and initial anti-rotation constraint within the triangular limiting structure further enhance the stability of the connection between the two by virtue of its own stability. After the cutting workpiece 102 is placed in place, by operating the three sets of actuating blocks 1012 on the top of the cutting disc 101, the rotating shaft 109 fixedly connected to the actuating blocks 1012 rotates in the rectangular groove 108, thereby driving the eccentric locking block 1011 on the surface of the rotating shaft 109 to rotate synchronously. As the actuating blocks 1012 rotate, the eccentric locking block 1011 will gradually rotate into the second arc-shaped locking groove 1022 on the top of the cutting workpiece 102. Utilizing the characteristics of the eccentric structure, a double clamping force of axial and radial force is formed on the cutting workpiece 102, further restricting the movement and rotation of the cutting workpiece 102.
