Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing equipment technology, and in particular to a vibration measuring device for CNC machine tool fault detection. Background Technology
[0002] A CNC machine tool is a type of machine tool whose movement is controlled by a computer control system. Its control system logically processes programs with control codes or other symbolic instructions, decodes them, represents them with coded numbers, and inputs them into the CNC device via an information carrier. After processing, the CNC device sends out various control signals to control the machine tool's movements, automatically machining parts according to the shape and dimensions required by the drawings.
[0003] A vibration meter, also known as a vibration analyzer or vibration pen, is a measuring instrument used to measure the amplitude, velocity, acceleration, and frequency of a vibrating system. Vibration meters come in various types, such as portable handheld and split-type. Portable handheld vibration meters are typically small, lightweight, easy to carry and operate, and suitable for on-site testing and fault diagnosis. Split-type vibration meters may offer higher accuracy and more measurement functions, making them suitable for applications with more stringent requirements for vibration parameters.
[0004] Traditional devices may not be designed for easy replacement of probes. When different types of CNC machine tools or different fault modes need to be detected, technicians may need to make large-scale adjustments to or replace the entire vibration measurement equipment, which greatly reduces the flexibility of the equipment. When the probe malfunctions or needs to be calibrated, technicians may need to spend a lot of time and effort on complex disassembly work, which not only reduces the maintenance efficiency of the equipment, but also increases the downtime caused by equipment failure. Utility Model Content

[0016] This utility model has the following beneficial technical effects:
[0017] This invention, by incorporating a convenient disassembly component, allows for the adjustment of the slider and positioning plate position by rotating the handle, thereby facilitating the installation and removal of the insertion block. When the probe malfunctions or requires calibration, technicians can quickly disassemble and replace it without spending a significant amount of time on complex disassembly work. This greatly improves equipment maintenance efficiency and reduces downtime caused by equipment failure. The easy-to-install and disassemble probe can more readily adapt to different testing needs.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0024] This utility model proposes a vibration measuring device for CNC machine tool fault detection. Please refer to the attached drawings. Figures 1-4 As shown, the device includes a vibration meter body 1, a probe head 4, and a detachable assembly. The vibration meter body 1 is equipped with a control button 3. The probe head 4 is inserted into the vibration meter body 1. The detachable assembly is installed on the vibration meter body 1 and is used to disassemble and install the probe head 4 in the working state. The detachable assembly includes a positioning mechanism for fixing the probe head 4 and a transmission mechanism for driving the positioning mechanism.
[0025] As one embodiment of this utility model, please refer to the accompanying drawings. Figures 1-2 As shown, specifically, the vibration meter body 1 is equipped with a display screen 2 for displaying the test results, and a ring rope 6 is provided on one side of the vibration meter body 1.
[0026] As one embodiment of this utility model, please refer to the accompanying drawings. Figures 3-4 As shown, specifically, a plug 10 is provided on one side of the probe head 4. The plug 10 is inserted into the vibration meter body 1. A power-on module 15 for driving the probe head 4 is provided on the plug 10.
[0027] As one embodiment of this utility model, please refer to the accompanying drawings. Figure 4As shown, specifically, the positioning mechanism includes a threaded post 8, a guide rod 9, a slider 12, and a positioning plate 13; the threaded post 8 is rotatably disposed on the inner walls of both ends of the vibration meter body 1, and the outer peripheral wall of the threaded post 8 is provided with two sets of threads with opposite directions; the guide rod 9 is disposed inside the vibration meter body 1; the slider 12 is slidably disposed inside the vibration meter body 1 and located on both sides of the insert block 10, one end of the slider 12 is threadedly connected to the threaded post 8, and the other end is slidably connected to the guide rod 9; the positioning plate 13 is disposed on one side of the slider 12 and is fitted into the insert block 10, and the insert block 10 is provided with a rectangular groove 14 that fits into the slider 12.
[0028] As one embodiment of this utility model, please refer to the accompanying drawings. Figure 4 As shown, specifically, the transmission mechanism includes a rotating handle 5, a worm 7, and a worm wheel 11; the worm 7 is vertically rotatably mounted on the vibration meter body 1; the rotating handle 5 is located at the top of the worm 7 and outside the vibration meter body 1; the worm wheel 11 is mounted on the threaded column 8 and meshes with the worm 7. The cooperation between the worm 7 and the worm wheel 11 has a self-locking function, that is, when the transmission device stops moving, the output shaft can maintain its position and will not reverse due to the reverse action of the load. Therefore, it can prevent the threaded column 8 from reciprocating after the positioning plate 13 positions the insert block 10, which would cause the probe head 4 to become loose. It can ensure that the threaded column 8 maintains a stable transmission effect under various conditions, thereby improving the stability of the positioning plate 13.
[0029] In summary, when using this invention, the vibration meter body 1 needs to contact the probe head 4 with the workpiece of the CNC machine tool when measuring vibration. Therefore, after long-term use, the probe head 4 will wear out and needs to be replaced. The worm gear 7 is driven to rotate by manually turning the handle 5. Since the worm gear 7 meshes with the worm wheel 11, it drives the worm wheel 11 and the threaded column 8 to rotate. This causes multiple sets of sliders 12 and positioning plates 13 to move relatively closer or further away on the threaded column 8 and guide rod 9. When the sliders 12 and positioning plates 13 move relatively away until they disengage from the insert block 10, the positioning of the insert block 10 can be released, and the insert block 10 and probe head 4 can be removed from the vibration meter body 1 for replacement. When the probe head 4 malfunctions or needs calibration, technicians can quickly disassemble and replace it without spending a lot of time on complicated disassembly work. This greatly improves the maintenance efficiency of the vibration meter body 1 and reduces downtime caused by the failure of the vibration meter body 1.
[0030] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
