Description

Technical Field

[0001] This utility model relates to the technical field of turrets, and in particular to a high-precision turret testing platform with anti-vibration and buffering functions. Background Technology

[0002] A tool turret is a tool clamping and switching device on CNC lathes, turning centers, and other equipment. It has multiple tool mounting positions to accommodate different types and sizes of cutting tools. Through servo or hydraulic drive, it achieves rapid and precise tool switching, enabling various machining operations such as grooving, drilling, reaming, boring, and finishing. The precision and stability of the tool turret directly determine the machining quality and operational reliability of the machine tool. Therefore, after the tool turret is manufactured or during long-term use and maintenance, its key performance indicators must be tested and verified using testing equipment to ensure that it meets design standards and usage requirements.

[0003] Currently, existing turret testing devices typically include a testing platform, a drive system, a testing system, and a control system. The testing platform, as the foundation of the entire device, is responsible for mounting the turret under test, the drive system, and some testing components. The turret under test usually has a certain weight, and during the process of placing it on the testing platform using hoisting or handling mechanisms, impact loads are inevitably generated, accompanied by vibration. However, testing platforms mostly use rigid support structures, relying solely on the toughness of their own materials for limited buffering, resulting in insufficient vibration damping performance. The impact load during loading is directly transmitted to the main body of the testing platform and the internally installed testing components, easily causing slight deformation of the testing platform's reference surface, disrupting the consistency of the testing reference. Long-term repeated impact vibrations will exacerbate fatigue damage to the testing platform structure, shorten its service life, and may also damage precision testing components, increasing equipment maintenance costs. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a high-precision turret testing platform with anti-vibration buffer function that ensures the stability of the testing benchmark and improves the testing accuracy.

[0005] This utility model discloses a high-precision turret testing platform with vibration damping function, comprising a base, a mounting platform, a vibration damping mechanism, and a locking mechanism. The mounting platform is flexibly connected to the base through the vibration damping mechanism, and the mounting platform is provided with mounting holes corresponding to the turret to be tested. The vibration damping mechanism includes a first buffer component arranged in the vertical direction and a second buffer component arranged in the horizontal direction. The locking mechanism is disposed on the base and can selectively act to rigidly lock the mounting platform to the base.

[0006] As a preferred embodiment of this utility model, the first buffer assembly includes an upper connecting plate, a lower connecting plate, a plurality of guide posts, and a buffer spring; the upper connecting plate is fixedly connected to the mounting platform, and the lower connecting plate is connected to the base; the plurality of guide posts are evenly distributed, and one end of each guide post is fixedly connected to the upper connecting plate, and the other end is slidably connected to the lower connecting plate; the buffer spring is sleeved on the outside of the guide post, and both ends abut against the upper connecting plate and the lower connecting plate respectively.

[0007] As a preferred embodiment of the present invention, the second buffer assembly includes an elastic connector and a damper; one end of the elastic connector is connected to the upper connecting plate and the other end is connected to the base, and is arranged in a horizontal direction; the damper is arranged parallel to the elastic connector, and its two ends are respectively hinged to the upper connecting plate and the base.

[0008] As a preferred embodiment of this utility model, at least three sets of the second buffer components are evenly arranged along the circumference of the mounting platform.

[0009] As a preferred embodiment of this utility model, the locking mechanism includes a locking seat, a locking pin, and a driving component; the locking seat is fixed to the bottom of the mounting platform, the locking pin is slidably disposed on the base in the vertical direction and corresponds to the locking hole on the locking seat; the driving component is disposed on the base, and its output end is connected to the locking pin for driving the locking pin to insert into or retract from the locking hole.

[0010] As a preferred embodiment of this utility model, the locking mechanism further includes a guide seat, which is fixed on the base, and the locking pin slides with the guide seat.

[0011] As a preferred embodiment of this utility model, the locking mechanism further includes a vibration sensor and a controller. The vibration sensor is mounted on the mounting platform, and the controller is connected to the vibration sensor and the driving component.

[0012] As a preferred embodiment of this utility model, the bottom of the base is provided with leveling feet and shock-absorbing pads. The leveling feet are evenly distributed along the circumference of the base, and the shock-absorbing pads are provided at the end of the leveling feet that contacts the ground.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The base, mounting platform, shock-absorbing mechanism, and locking mechanism, when placing the turret under test, attenuate the vertical and horizontal impacts and vibrations by the shock-absorbing mechanism, which includes the first and second buffer components. This protects the accuracy of the reference surface of the test table and the internal testing components, thereby ensuring the consistency of the testing reference. The locking mechanism can rigidly lock the mounting platform during the testing phase, preventing the worktable surface supporting the turret from lacking sufficient rigid support and positional stability during the testing process, which would affect the certainty of the measurement reference and the repeatability of the test results.

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Reference Figures 1-2 This embodiment provides a high-precision turret testing platform with vibration damping function, including a base 1, a mounting platform 2, a vibration damping mechanism 3, and a locking mechanism 4. The base 1 is the basic support structure of the entire device and can be made of cast iron or welded steel with sufficient rigidity to provide a stable foundation. The mounting platform 2 is used to support and fix the turret to be tested. Its top is machined with mounting holes 21 for connecting the turret. The distribution and size of the mounting holes 21 match the mounting interface of the turret to be tested, ensuring that the turret can be accurately and firmly installed. The vibration damping mechanism 3 connects to the mounting platform 4. Connected between the base 1 and the mounting platform 2, it enables a flexible connection between the mounting platform 2 and the base 1. This allows it to absorb and attenuate energy during impact vibrations generated during the hoisting or operation of the turret, preventing direct transmission to the base 1 and the detection elements mounted on it. The locking mechanism 4 is located on the base 1. When absolute stability of the detection process is required, it can actively lock the mounting platform 2, which was originally in a flexible buffer state, onto the base 1, thereby eliminating any minor displacement that the anti-vibration buffer mechanism 3 may cause and providing a rigid reference platform for detection.

[0018] To further enhance the overall stability of the testing platform and its ability to isolate vibrations from the external environment, leveling feet 11 and vibration damping pads 12 are installed at the bottom of the base 1. Multiple leveling feet 11 are evenly distributed along the circumference of the base 1, and each leveling foot 11 has a threaded adjustment structure for precisely adjusting the levelness of the base 1 to ensure that the entire testing platform is on an ideal working plane. The vibration damping pads 12 are made of high-damping elastic materials such as rubber and polyurethane, and are installed at the end of the leveling feet 11 that contacts the ground, which can isolate low-frequency vibrations transmitted from the ground.

[0019] Specifically, refer to Figure 3 The shock-absorbing buffer mechanism 3 includes a first buffer component 31 arranged in the vertical direction and a second buffer component 32 arranged in the horizontal direction. The first buffer assembly 31 is used to buffer vertical impact loads and includes an upper connecting plate 311, a lower connecting plate 312, several guide posts 313, and a buffer spring 314. The upper connecting plate 311 is fixedly connected to the bottom surface of the mounting platform 2, and the lower connecting plate 312 is fixedly connected to the base 1. The several guide posts 313 are evenly distributed in a rectangular or circular shape between the upper and lower connecting plates. The upper end of each guide post 313 is fixedly connected to the upper connecting plate 311, and the lower end passes through the corresponding guide hole on the lower connecting plate 312 and can slide along it. The buffer spring 314 is sleeved on the outside of the guide post 313. The upper connecting plate 311 and the lower connecting plate 312 are respectively attached to the side. When the mounting platform 2 is subjected to a downward impact, the upper connecting plate 311 drives the guide column 313 to compress the buffer spring 314 and move downward. The elastic deformation of the buffer spring 314 absorbs and stores most of the impact energy, and then slowly releases the energy, thereby converting the sharp impact pulse into a smooth vibration and attenuating it. The sliding cooperation between the guide column 313 and the lower connecting plate 312 ensures the trajectory accuracy of the mounting platform 2 when it moves in the vertical direction, prevents it from tilting or deviating, and ensures the stability of the buffering process. The second buffer assembly 32 is used to withstand horizontal vibrations and swaying, including an elastic connector 321 and a damper 322. The elastic connector 321 can be a metal-rubber composite, a high-damping rubber block, or an airbag, etc. One end of it is connected to the upper connecting plate 311 of the first buffer assembly 31 or directly to the mounting platform 2, and the other end is connected to the side wall of the base 1, and is arranged in the horizontal direction. The damper 322 can be a hydraulic damper or a gas damper, and is arranged parallel to the elastic connector 321. Its two ends are respectively connected to the base 1 via ball joints or spherical bearings. The upper connecting plate 311 and the base 1 are hinged; the elastic connector 321 provides flexible support and restoring force in the horizontal direction, allowing the mounting platform 2 to undergo horizontal displacement within a certain range to buffer lateral impact; while the damper 322, through its internal viscous damping or throttling damping effect, quickly consumes horizontal vibration energy, suppresses the swaying and residual oscillation of the mounting platform 2 on the horizontal plane, and enables it to quickly return to a static state; the hinged connection method can avoid installation stress and adapt to the small angle changes that the mounting platform 2 may produce during the buffering process.

[0020] To further enhance the balance and stability of the horizontal buffer, at least three sets of the second buffer components 32 are evenly distributed along the circumference of the mounting platform 2; for example, three sets can be distributed at 120-degree intervals, or four sets can be distributed at 90-degree intervals. This symmetrical arrangement ensures that impact forces from any horizontal direction can be evenly absorbed and suppressed, preventing the mounting platform 2 from twisting or shifting to one side during the buffering process. This ensures that the mounting platform 2 moves smoothly on the horizontal plane and maintains a good center position, so that it can automatically return to the center after the buffering is completed, providing an accurate position reference for the inspection work.

[0021] The locking mechanism 4 includes a locking seat 41, a locking pin 42, and a driving component 43. The locking seat 41 is fixedly installed at the bottom of the mounting platform 2, and has a conical or cylindrical locking hole 411. The locking pin 42 is slidably mounted on the base 1 in the vertical direction, and its top end matches the locking hole 411. The driving component 43 can be an electric push rod, a pneumatic cylinder, or a hydraulic cylinder, which is fixed on the base 1 and its output end is connected to the locking pin 42. When it is necessary to switch from the buffer mode to the detection mode, the driving component 43 is activated, pushing the locking pin 42 upward so that it is precisely inserted into the locking hole 411 of the locking seat 41 at the bottom of the mounting platform 2, thereby rigidly connecting the mounting platform 2 and the base 1 in the vertical and horizontal directions, completely eliminating the relative movement between the two, and forming a stable rigid detection platform. After the detection is completed, the driving component 43 can drive the locking pin 42 out of the locking hole 411, so that the shock-absorbing buffer mechanism 3 can resume its function.

[0022] To ensure the smooth and precise alignment of the locking pin 42, the locking mechanism 4 also includes a guide seat 44. The guide seat 44 is fixed to the base 1 and has a guide hole machined inside or a linear bearing installed thereon. The locking pin 42 passes through the guide seat 44 and slides with clearance fit with it. The guide seat 44 provides linear guidance for the up and down movement of the locking pin 42, preventing it from deviating or getting stuck during the movement, and ensuring that the locking pin 42 can be accurately inserted into the locking hole 411 each time it is locked, thereby improving the reliability of the locking action and the repeatability of the positioning accuracy.

[0023] To further automate and enhance the locking mechanism, the locking mechanism 4 also includes a vibration sensor 45 and a controller. The vibration sensor 45 is mounted on the mounting platform 2 to monitor the vibration status of the mounting platform 2 in real time. The controller can be a PLC or an embedded controller, electrically connected to the vibration sensor 45 and the drive unit 43. During stages where impacts may occur, such as when the turret is being loaded, the mounting platform 2 is in a free buffer state. When the vibration sensor 45 detects that the vibration amplitude and frequency of the mounting platform 2 have decayed to below a preset stability threshold, the controller sends a command to the drive unit 43, which drives the locking pin 42 to rise and complete the rigid locking. This avoids delays or errors caused by manual judgment and operation, and achieves automatic switching from impact buffering to stable detection, improving detection efficiency and intelligence.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
