Description

Technical Field

[0001] This utility model relates to the field of machine tool optomechanics, and in particular to a CNC machine tool optomechanical horizontal positioning device. Background Technology

[0002] In CNC machine tool machining, horizontal positioning of the optical engine is a crucial step in ensuring machining accuracy and workpiece quality. Traditionally, horizontal positioning devices are placed directly on the machining center, and a bubble level is used to observe and adjust the engine's level. However, this traditional positioning method has a number of problems and shortcomings.

[0003] First, with existing horizontal positioning devices, operators need to frequently check the bubble level to determine if further adjustments are necessary. This method is not only cumbersome but also inefficient, as each adjustment requires stopping work to observe whether the bubble is centered. This not only affects processing efficiency but may also lead to the accumulation of processing errors due to frequent adjustments.

[0004] Therefore, it is necessary to provide a new optical-mechanical horizontal positioning device for CNC machine tools to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a CNC machine tool optical-mechanical horizontal positioning device.

[0006] The CNC machine tool optical-mechanical horizontal positioning device provided by this utility model includes: a machine tool optical-mechanical body, a connecting block, and a fixing mechanism. A movable machining center is installed at the top of the machine tool optical-mechanical body, and connecting feet are equidistantly installed at the bottom of the machine tool optical-mechanical body. Support bolts are rotatably connected inside the connecting feet. A connecting block is placed at the axis of the machining center, and a rotating rod is rotatably connected at the axis of the connecting block. A centered bubble level is rotatably connected to one end of the rotating rod near the connecting block. A fixing mechanism is installed inside the connecting block, and the connecting block is fixed at the axis of the machining center by the fixing mechanism.

[0007] Preferably, the fixing mechanism includes: a gear, a worm gear, a worm, a rack, and a clamping head. The gear is rotatably connected inside the connecting block, and the top of the gear is fixedly connected to the worm gear. The worm is rotatably connected inside the connecting block, and the worm gear meshes with the worm. The racks are symmetrically slidably connected inside the connecting block, and both racks mesh with the gear. The clamping head is fixedly connected to the ends of the two racks that are far apart from each other.

[0008] Preferably, the rotating rod has an extension rod that is slidably connected inside. The extension rod has a hollow interior and a spring piece is engaged with the inner wall of the extension rod. One end of the spring piece is fixedly connected with a spherical locking block. The rotating rod has slots that are equidistantly spaced inside, and the spherical locking block engages with one of the slots.

[0009] Preferably, a vertical rod is slidably connected to the end of the extension rod away from the rotating rod, and slots are provided at equal intervals at one end of the vertical rod. A pin is inserted into the inner wall of the slot, and a connecting platform is fixedly connected to the bottom end of the vertical rod. An extended bubble level is rotatably connected to the center of the connecting platform.

[0010] Preferably, both ends of the worm gear and the top of the support bolt are provided with internal hexagonal grooves.

[0011] Preferably, rubber pads are fixedly connected to the inner walls of both clamping heads.

[0012] Preferably, the connecting block, rotating rod, extension rod, and vertical rod are all designed to be lightweight.

[0013] Compared with related technologies, the CNC machine tool optical-mechanical horizontal positioning device provided by this utility model has the following beneficial effects:

[0014] Significantly improve adjustment efficiency:

[0015] Through the ingenious design of the rotating rod, extension rod, and vertical rod, the bubble level is extended to the vicinity of the support bolts of the machine tool body. Operators no longer need to frequently get up and move to the top of the machining center to view the bubble level, thus greatly reducing the number of interruptions during the adjustment process and significantly improving adjustment efficiency.

[0016] Enhance the accuracy and stability of adjustments:

[0017] Extending the use of the bubble level allows operators to observe the level of the machine tool body more directly and accurately, and make fine adjustments based on the bubble position, thereby improving the accuracy of the adjustment. Meanwhile, the fixing mechanism employs a worm gear drive and rack and pinion clamping design, ensuring the stability of the machining center during adjustment and preventing a decrease in positioning accuracy due to loosening or deformation.

[0018] Improve ease of use and comfort:

[0019] This device prioritizes the operator's experience, employing a lightweight design and meticulous details such as hexagonal grooves to make operation simpler and more comfortable. Operators can easily make adjustments using tools like hex wrenches, reducing operational difficulty and physical exertion.

[0020] Enhance the adaptability and flexibility of the device:

[0021] The rotating rod, extension rod, and vertical rod can all be adjusted as needed, allowing this device to adapt to machining centers of different sizes and weights, as well as machine tool bodies of different shapes and sizes. This design also increases the device's flexibility in complex environments. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. 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.

[0027] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0028] Please see Figure 1-3 A CNC machine tool optical-mechanical horizontal positioning device includes: a machine tool optical-mechanical body 1, a connecting block 5, and a fixing mechanism 8. A movable machining center 2 is installed at the top of the machine tool optical-mechanical body 1. Connecting feet 3 are equidistantly installed at the bottom of the machine tool optical-mechanical body 1. Support bolts 4 are rotatably connected inside the connecting feet 3. A connecting block 5 is placed at the axis of the machining center 2. A rotating rod 6 is rotatably connected at the axis of the connecting block 5. A centered bubble level is rotatably connected to one end of the rotating rod 6 near the connecting block 5. A fixing mechanism 8 is installed inside the connecting block 5 to fix the connecting block 5 at the axis of the machining center 2.

[0029] It should be noted that a connecting block 5 is cleverly placed at the axis of machining center 2. Connecting block 5 serves not only as the rotation connection point of the rotating rod 6 but also as the installation position of the fixing mechanism 8. The end of the rotating rod 6 near connecting block 5 is rotatably connected to a centered bubble level. This design allows the operator to visually observe the levelness of the machine tool body 1, providing an accurate reference for adjusting the support bolts 4.

[0030] Please see Figure 2The fixing mechanism 8 includes: a gear 81, a worm gear 82, a worm 83, a rack 84, and a clamping head 85. The gear 81 is rotatably connected to the inner wall of the connecting block 5. The worm gear 82 is fixedly connected to the top of the gear 81. The worm 83 is rotatably connected inside the connecting block 5. The worm gear 82 meshes with the worm 83. The racks 84 are symmetrically slidably connected inside the connecting block 5. Both racks 84 mesh with the gear 81. The clamping head 85 is fixedly connected to the ends of the two racks 84 that are far apart from each other. The two ends of the worm 83 and the top of the support bolt 4 are provided with internal hexagonal grooves 13. Rubber pads are fixedly connected to the inner walls of the two clamping heads 85.

[0031] It should be noted that the design of the fixing mechanism 8 integrates several key components, including gear 81, worm gear 82, worm 83, rack 84, and clamping head 85, forming a highly efficient and stable clamping system. Gear 81 rotates within the connecting block 5 and is fixedly connected to worm gear 82, forming the core of power transmission. The meshing connection between worm gear 83 and worm gear 82 allows the rotation of worm gear 83 to drive the rotation of worm gear 82 and gear 81.

[0032] The racks 84 symmetrically and slidingly connected inside the connecting block 5 mesh with the gears 81. When the gears 81 rotate, they can drive the two racks 84 to slide in opposite or opposite directions inside the connecting block 5. The sliding of the racks 84 further drives the clamping head 85 fixed at its end to move, thereby clamping or releasing the machining center 2.

[0033] Both ends of the worm gear 83 and the top of the support bolt 4 are designed with internal hexagonal grooves 13, which not only facilitates rotation using tools such as an internal hexagonal wrench, but also improves the convenience and efficiency of operation. In addition, the rubber pad fixedly connected to the inner wall of the clamping head 85 enhances the friction and stability during clamping, while reducing damage to the surface of the machining center 2 during clamping.

[0034] Please see Figure 3 The rotating rod 6 has an extension rod 9 that is slidably connected inside. The extension rod 9 has a hollow interior and a spring piece 10 that is snapped into the inner wall of the extension rod 9. One end of the spring piece 10 is fixedly connected to a spherical locking block 11. The rotating rod 6 has slots 12 that are equidistantly opened inside. The spherical locking block 11 is snapped into one of the slots 12. The end of the extension rod 9 away from the rotating rod 6 is slidably connected to a vertical rod 14. One end of the vertical rod 14 has slots 15 that are equidistantly opened. The inner wall of the slots 15 is fitted with pins 16. The bottom end of the vertical rod 14 is fixedly connected to a connecting platform 17. The center of the connecting platform 17 is rotatably connected to an extended bubble level. The connecting block 5, the rotating rod 6, the extension rod 9, and the vertical rod 14 are all designed to be lightweight.

[0035] It should be noted that the extension rod 9, which is internally slidably connected to the rotating rod 6, has a unique design. A spring clip 10 is engaged inside the hollow interior of the extension rod 9. A spherical locking block 11 fixed at one end of the spring clip 10 securely engages with the slot 12 inside the rotating rod 6, achieving precise positioning and locking of the extension rod 9. Furthermore, the vertical rod 14, slidably connected to the end of the extension rod 9, can be flexibly adjusted in height and angle through the cooperation of the slot 15 and the pin 16. The connecting platform 17 at the bottom of the vertical rod 14 is rotatably connected to an extended bubble level, facilitating level detection at different positions on the machine tool body 1. In the overall design, the connecting block 5, rotating rod 6, extension rod 9, and vertical rod 14 are all made of lightweight materials, ensuring ease of operation and mobility of the device.

[0036] The working principle of the CNC machine tool optical-mechanical horizontal positioning device provided by this utility model is as follows:

[0037] Basic structure and installation:

[0038] The machine tool body 1 serves as the foundation of the entire device, with a movable machining center 2 mounted on its upper end. Connecting feet 3 are equidistantly installed at the bottom of the machine tool body 1, and support bolts 4 are rotatably connected inside the connecting feet 3 to adjust the overall levelness of the machine tool body 1.

[0039] A connecting block 5 is placed at the axis of the machining center 2. The connecting block 5, as the core component of the horizontal positioning device, has a fixing mechanism 8 installed inside for fixing the machining center 2. A rotating rod 6 is rotatably connected to the axis of the connecting block 5. The rotating rod 6 and its extension structure are used to extend the bubble level to the position of the support bolt 4 that needs adjustment.

[0040] Working principle of the fixed mechanism:

[0041] The fixing mechanism 8 includes a gear 81, a worm gear 82, a worm 83, a rack 84, and a clamping head 85. When it is necessary to fix the machining center 2, the operator usually uses a tool such as an Allen wrench to rotate the worm 83. The worm 83 meshes with the worm gear 82, driving the gear 81 to rotate. The rotation of the gear 81 drives the two symmetrical racks 84 to slide inside the connecting block 5, which in turn drives the two clamping heads 85 to move closer to the axis of the machining center 2 until the machining center 2 is firmly clamped in the connecting block 5.

[0042] Leveling adjustment and extension of the bubble level:

[0043] An extension rod 9 is slidably connected inside the rotating rod 6. The design of the extension rod 9 allows the bubble level to extend to any support bolt 4 at the bottom of the machine tool body 1. In this way, the operator does not need to frequently get up and move to the machining center 2 to view the bubble level, but can directly observe the bubble level near the machine tool body 1 and adjust the support bolt 4 according to the position of the bubble until the machine tool body 1 is level.

[0044] The extension rod 9 has a hollow interior and is fitted with a spring clip 10 and a spherical locking block 11. The spherical locking block 11 engages with a slot 12 inside the rotating rod 6, ensuring that the extension rod 9 remains stable in the adjusted position. This design allows operators to adjust the length of the extension rod 9 as needed to accommodate different adjustment requirements.

[0045] Use of vertical rod and extended bubble level:

[0046] The end of the extension rod 9 furthest from the rotating rod 6 is slidably connected to a vertical rod 14, and the bottom end of the vertical rod 14 is fixedly connected to a connecting platform 17. An extended bubble level is rotatably connected to the center of the connecting platform 17. This design allows the operator to extend the bubble level further to the bottom of the machine tool body 1, especially when fine-tuning or checking the levelness of a particular support bolt 4 is required.

[0047] The slots 15 and pins 16 on the vertical rod 14 are designed to allow the operator to adjust the height and angle of the vertical rod 14 as needed, ensuring that the bubble level can accurately reflect the horizontal state of the machine tool body 1.

[0048] Operation and maintenance:

[0049] The design of the entire device emphasizes ease of operation and maintenance. For example, the top of both the worm gear 83 and the support bolt 4 are provided with internal hexagonal grooves 13, making it easy to operate with tools such as internal hexagonal wrenches.

[0050] The connecting block 5, rotating rod 6, extension rod 9 and vertical rod 14 are all designed to be lightweight, which reduces the weight of the entire device and improves the ease of operation.
