Description

Technical Field

[0001] This utility model relates to the field of testing device technology, specifically to a rapid reliability testing device for vertical machining centers. Background Technology

[0002] This rapid reliability testing device for vertical machining centers can efficiently assess equipment operational stability. The device integrates multiple types of sensors (vibration, temperature, speed, etc.) and captures real-time operating parameters of key components such as the spindle and feed axes through a high-speed data acquisition unit. Combined with an embedded analysis system and fault warning algorithms, it quickly identifies abnormal characteristics and calculates reliability indicators such as mean time between failures (MTBF). Its modular design adapts to different machining center models, automates the testing process, and reduces testing time by more than 60% compared to traditional methods. It provides real-time data support for equipment maintenance and performance verification, improving testing efficiency and accuracy.

[0003] Utility model CN213828202U discloses a rapid reliability testing device for a vertical machining center, comprising: a frame and a top frame mounted on top of the frame. A main unit is mounted on the top of the frame, and the front surface of the main unit has multiple uniformly distributed strip-shaped heat dissipation holes. An operating cabinet is mounted on the front surface of the top frame, positioned above the main unit. Two side blocks are symmetrically fixed to the front surface of the main unit relative to the two sides of the strip-shaped heat dissipation holes, and a cover plate is slidably connected between the two side blocks. Through the provided side blocks, sliding strips, strip-shaped grooves, cover plate, base block, spring groove, telescopic locking strip, and strip-shaped locking holes, during periods when the testing instrument is not in use, the operator can lower the cover plate and engage it with the telescopic locking strip, thereby effectively blocking the strip-shaped heat dissipation holes on the front surface of the main unit. This prevents dust and chips from entering the strip-shaped heat dissipation holes, ensuring the cleanliness of the inside of the main unit.

[0004] In the aforementioned application, the cooperation between the slider and the detector and other components enables the shield to effectively block the heat dissipation holes during operation, but it is difficult to solve the problem of high-precision detection, resulting in low accuracy of the detector. Therefore, we propose a rapid reliability testing device for vertical machining centers. Utility Model Content

[0005] This utility model proposes a rapid reliability testing device for vertical machining centers.

[0006] The technical solution of this utility model is as follows: A vertical machining center reliability rapid testing device includes a machine body, a support column fixedly connected to the bottom of the machine body, a control center cabinet provided on the side of the machine body, a safety door slidably connected to the side of the machine body, a handle fixedly connected to the side of the safety door, a slide fixedly connected to the inner side of the machine body, a worktable fixedly connected to the top of the slide, a tool shaft fixedly connected to the inner side of the machine body, and a flatness testing mechanism provided inside the machine body;

[0007] The flatness detection mechanism includes a motor, the side of which is fixedly connected to the side of the machine body. A threaded rod is fixedly connected to the end of the motor output shaft. A sprocket is fixedly connected to one end of the threaded rod. A threaded rod is rotatably connected to the inner side of the machine body. A sprocket is fixedly connected to one end of the threaded rod. A chain is provided on the circumferential surface of the sprocket. The sprocket is connected to the sprocket through the chain. A threaded sleeve is threadedly connected to the circumferential surfaces of both the threaded rod and the threaded rod. A fixing frame is fixedly connected to the circumferential surface of the threaded sleeve. A detection probe is fixedly connected to the bottom of the fixing frame.

[0008] The number of support pillars is set to several and symmetrically arranged along the vertical central axis of the machine body, so that the machine body is subjected to uniform force, enhancing the overall stability and balance of the device, avoiding shaking during operation due to the shift of the center of gravity, thereby ensuring the accuracy of processing and testing. The side of the machine body is provided with heat dissipation vents, and the number of heat dissipation vents is set to several and arranged in a linear array along the side of the machine body, which can dissipate the heat generated by each component during the operation of the device in a timely manner, preventing the performance and service life of the components from being affected by excessive temperature, and maintaining the stable operation of the device.

[0009] The side of the machine body is provided with a sliding groove. The number of sliding grooves is set in a linear array on the side of the machine body. The side of the safety door is slidably connected to the inner side of the sliding groove, providing a stable sliding track for the safety door and ensuring the smoothness and accuracy of the safety door when it moves.

[0010] The number of detection probes is set to several and arranged in a linear array at the bottom of the fixed frame. The top of the worktable is located on the displacement trajectory of the detection probes. By using multiple detection probes to detect different positions on the worktable simultaneously or sequentially, the comprehensiveness and accuracy of flatness detection are improved, and the limitations of single-point detection are avoided.

[0011] The machine body is equipped with a cleaning mechanism, which includes a threaded sleeve II. The inner side of the threaded sleeve II is threadedly connected to the circumferential surfaces of the threaded rod I and the threaded rod II. A bracket is fixedly connected to the circumferential surface of the threaded sleeve II. A retainer is fixedly connected to the top of the bracket. A cleaning plate is engaged with the side of the retainer. A cleaning brush is fixedly connected to the bottom of the cleaning plate.

[0012] The cleaning brushes are arranged in a linear array at the bottom of the cleaning plate, and the top of the workbench is located on the displacement trajectory of the cleaning brushes. By using multiple cleaning brushes to clean different areas of the workbench surface at the same time, the coverage of a single cleaning is expanded, the cleaning efficiency and comprehensiveness are improved, and the detection accuracy and processing quality are avoided due to residual debris in cleaning dead corners.

[0013] Both sprocket one and sprocket two have spokes on their sides. The spokes are arranged in a circular array on the sides of sprocket one and sprocket two. This reduces the weight of the sprockets while ensuring their structural strength, thereby reducing inertia and energy consumption during rotation. The number of teeth on sprocket one is equal to the number of teeth on sprocket two, ensuring the synchronization and accuracy of power transmission and preventing transmission errors caused by differences in rotational speed.

[0014] The card holder has slots on its side, and the number of slots is set to several and arranged in a linear array on the side of the card holder, providing multiple selectable installation or snap-fit ​​positions, enhancing the versatility and adaptability of the device, facilitating quick positioning and installation, and improving assembly efficiency.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] 1. This utility model utilizes the coordinated operation of components such as the threaded rod, sprocket, and chain within the flatness detection mechanism to drive the threaded rod two to rotate synchronously, causing the threaded sleeve one and the fixed frame to move. Combined with the detection probes in the bottom linear array, it can perform flatness detection on multiple positions on the top of the worktable. The equal number of teeth on sprocket one and sprocket two ensures synchronous transmission, and the multi-probe layout enhances the comprehensiveness of the detection, enabling rapid and accurate judgment of the worktable flatness. This provides efficient support for the reliability testing of vertical machining centers, ensuring the accuracy of subsequent machining.

[0017] 2. This utility model utilizes the cooperation of components such as the mounting bracket, cleaning plate, and cleaning brushes within the cleaning mechanism. The cleaning brushes in a linear array at the bottom clean the surface of the workbench. The snap-fit ​​design between the mounting bracket and the cleaning plate facilitates the disassembly and assembly of the cleaning plate, making it easy to replace or clean the cleaning brushes. The multiple cleaning brushes layout can thoroughly clean debris and debris from the workbench, preventing them from affecting the detection accuracy and processing quality. At the same time, the use of threaded rod transmission enables linkage with the detection mechanism without the need for additional power, saving costs and efficiently ensuring the overall practicality and reliability of the workbench cleaning and lifting device.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0027] Example 1

[0028] like Figures 1-5 As shown, this embodiment proposes a rapid reliability testing device for a vertical machining center, including a machine body 1, a support column 2 fixedly connected to the bottom of the machine body 1, a control center cabinet 3 provided on the side of the machine body 1, a safety door 4 slidably connected to the side of the machine body 1, a handle 5 fixedly connected to the side of the safety door 4, a slide 6 fixedly connected to the inner side of the machine body 1, a worktable 7 fixedly connected to the top of the slide 6, a tool shaft 8 fixedly connected to the inner side of the machine body 1, and a flatness testing mechanism 9 provided inside the machine body 1.

[0029] The flatness testing mechanism 9 includes a motor 91, which is fixedly connected to the side of the machine body 1. A threaded rod 92 is fixedly connected to the end of the output shaft of the motor 91. A sprocket 93 is fixedly connected to one end of the threaded rod 92. A threaded rod 94 is rotatably connected to the inner side of the machine body 1. A sprocket 95 is fixedly connected to one end of the threaded rod 94. A chain 96 is provided on the circumferential surface of the sprocket 93. The sprocket 93 is connected to the sprocket 95 via the chain 96. A threaded sleeve 97 is threadedly connected to the circumferential surface of both the threaded rod 92 and the threaded rod 94. A fixing frame 98 is fixedly connected to the circumferential surface of the threaded sleeve 97. A testing probe 99 is fixedly connected to the bottom of the fixing frame 98.

[0030] The number of support pillars 2 is set to be several, and they are symmetrical to each other along the vertical central axis of the machine body 1, so that the machine body 1 is subjected to uniform force, enhancing the overall stability and balance of the device, avoiding shaking during operation due to the shift of the center of gravity, thereby ensuring the accuracy of processing and testing. The side of the machine body 1 is provided with heat dissipation vents, and the number of heat dissipation vents is set to be several, and they are arranged in a linear array on the side of the machine body 1, which can dissipate the heat generated by each component during the operation of the device in a timely manner, preventing the performance and service life of the components from being affected by excessive temperature, and maintaining the stable operation of the device.

[0031] The side of the body 1 is provided with a sliding groove. There are several sliding grooves arranged in a linear array on the side of the body 1. The side of the safety door 4 is slidably connected to the inner side of the sliding groove, providing a stable sliding track for the safety door 4 and ensuring the smoothness and accuracy of the safety door 4 when it moves.

[0032] The number of detection probes 99 is set to several and arranged in a linear array at the bottom of the fixed frame 98. The top of the worktable 7 is located on the displacement trajectory of the detection probes 99. By using multiple detection probes 99 to detect different positions of the worktable 7 simultaneously or sequentially, the comprehensiveness and accuracy of flatness detection are improved, and the limitations of single-point detection are avoided.

[0033] In this embodiment, the operator starts the motor 91, whose output shaft drives the threaded rod 92 to rotate. This rotation is then carried by the sprocket 93, chain 96, and sprocket 95, causing the threaded rod 94 to rotate synchronously. This causes the threaded sleeve 97 and the fixing frame 98 to move accordingly. Combined with the multiple detection probes 99 in the bottom linear array, a comprehensive inspection of the top of the worktable 7 can be performed. The equal number of teeth on sprockets 93 and 95 ensures synchronous transmission, guaranteeing the stability and consistency of the inspection process. The layout of multiple detection probes 99 can cover more areas of the worktable 7, avoiding the limitations of single-point inspection, improving the comprehensiveness and accuracy of the inspection, and quickly obtaining the flatness data of the worktable 7. This provides an accurate basis for the reliability assessment of the vertical machining center, effectively ensuring the accuracy of subsequent processing. The overall design is efficient and practical, enhancing the detection capability and reliability of the device.

[0034] Example 2

[0035] like Figures 1-5 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes a cleaning mechanism 10. The cleaning mechanism 10 includes a threaded sleeve 101. The inner side of the threaded sleeve 101 is threadedly connected to the circumferential surfaces of the threaded rod 92 and the threaded rod 94. A bracket 102 is fixedly connected to the circumferential surface of the threaded sleeve 101. A card seat 103 is fixedly connected to the top of the bracket 102. A cleaning plate 104 is snapped onto the side of the card seat 103. A cleaning brush 105 is fixedly connected to the bottom of the cleaning plate 104.

[0036] The number of cleaning brushes 105 is set to several and arranged in a linear array at the bottom of the cleaning plate 104. The top of the worktable 7 is located on the displacement trajectory of the cleaning brushes 105. By using multiple cleaning brushes 105 to clean different areas of the worktable 7 surface at the same time, the coverage of a single cleaning is expanded, the cleaning efficiency and comprehensiveness are improved, and the detection accuracy and processing quality are avoided due to residual debris in cleaning dead corners.

[0037] Both sprocket 1 (93) and sprocket 2 (95) have spokes on their sides. The number of spokes is set to a certain amount and is arranged in a circumferential array on the sides of sprocket 1 (93) and sprocket 2 (95). While ensuring the structural strength of the sprocket, the weight of the sprocket itself is reduced, and the inertia and energy consumption during rotation are reduced. The number of teeth of sprocket 1 (93) is equal to the number of teeth of sprocket 2 (95), which ensures the synchronization and accuracy of power transmission and prevents transmission errors caused by differences in rotational speed.

[0038] The side of the card holder 103 is provided with card slots. The number of card slots is set to several and arranged in a linear array on the side of the card holder 103, providing multiple selectable installation or snap-fit ​​positions, enhancing the versatility and adaptability of the device, facilitating quick positioning and installation, and improving assembly efficiency.

[0039] In this embodiment, the rotation of threaded rod 1 92 and threaded rod 2 94 drives the threaded sleeve 2 101, bracket 102 and cleaning plate 104 to move. Multiple cleaning brushes 105 in a linear array at the bottom clean the surface of the workbench 7. The snap-fit ​​design of the card holder 103 and the cleaning plate 104, together with the card slots of the linear array on the side, facilitates quick and easy disassembly and assembly of the cleaning plate 104 for replacement or cleaning of the cleaning brushes 105. The layout of multiple cleaning brushes 105 can expand the cleaning range to ensure that the workbench 7 is clean without dead corners, avoid the impact of debris on detection accuracy and processing quality, and improve the overall practicality, stability and operating efficiency of the device.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
