Description

Technical Field

[0001] This utility model belongs to the technical field of workbench testing equipment, and in particular relates to a tooling structure for testing the accuracy of a rotary workbench surface. Background Technology

[0002] The rotary table is an indispensable key functional component in CNC machine tools, machining centers, and other precision machinery, playing a central role in modern intelligent manufacturing. Its main function is to provide precise continuous circumferential feed and accurate indexing and positioning capabilities for workpieces. This allows complex parts to efficiently complete multiple machining surfaces and multiple processes in a single setup, greatly improving machining efficiency and avoiding cumulative errors caused by repeated setups. From engine blades in the aerospace field to complex cavities in precision molds, the machining quality highly depends on the performance of the rotary table. Rotational accuracy, namely the radial runout, axial runout, and angular positioning accuracy during rotation, directly determines the workpiece's form and position tolerances, surface finish, and relative positional accuracy between various features. Therefore, regular and rigorous testing and calibration of the rotary table's surface accuracy is not only crucial for ensuring the processing quality of individual parts but also an important foundation for ensuring the stability of the entire manufacturing system and product consistency. It is of great significance for enhancing the core competitiveness of enterprises. In the accuracy testing process, a core preparatory step is to precisely align and coincide the center of the rotary table with the reference disc fixture.

[0003] Existing tooling structures for detecting the accuracy of rotary worktables still have some problems during use. For example, the industry currently still widely uses the traditional scribing and centering method, which is highly dependent on the operator's experience and skill. Its error varies from person to person, and even the smallest centering error is usually above 0.5mm, which is significantly uncontrollable. This inherent lack of accuracy often leads to the failure of subsequent accuracy tests, which not only consumes a lot of time and manpower for repeated adjustments, but also makes it difficult to meet the stringent requirements of modern manufacturing for high precision, high efficiency and high consistency. It has become a technical bottleneck restricting the improvement of production efficiency and quality.

[0004] To address this issue, we provide a tooling structure for detecting the accuracy of a rotary worktable. Utility Model Content

[0005] The purpose of this invention is to provide a tooling structure for detecting the accuracy of a rotary worktable. Through the structural cooperation of the vertical moving component and the horizontal moving component, it solves the problem that the existing technology for detecting the accuracy of a rotary worktable still relies on the traditional scribing and centering method, which is highly dependent on the operator's experience and skill. Its error varies from person to person and has significant uncontrollability.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model is a tooling structure for detecting the accuracy of a rotary worktable, including a rotary worktable, a base on one side of the rotary worktable, a column on the top of the base, a vertical moving component on one side of the column, a horizontal moving component on the top of the rotary worktable, a power component on one side of the column, a sensor on the top of the base, and a disc fixing component on the top of the rotary worktable.

[0008] The present invention is further provided that the base has bottom holes at all four corners, and expansion bolts are installed inside the bottom holes.

[0009] The present invention is further configured such that both the base and the column have mounting through holes, and mounting bolts are threaded into the mounting through holes.

[0010] The present invention is further configured such that the vertical moving component includes a guide rail disposed on one side of the column, a rack disposed on one side of the column, and a sliding plate disposed on one side of the column.

[0011] The present invention is further configured such that fixing holes are provided inside both the guide rail and the rack, and a sliding groove adapted to the guide rail and the rack is provided on one side of the slide plate.

[0012] The present invention is further configured such that the lateral movement component includes a cantilever disposed on one side of the column, and a telescopic arm disposed inside the cantilever.

[0013] The present invention is further configured such that the power assembly includes a first gearbox disposed on one side of the column, a first motor fixedly connected to one side of the first gearbox, a second gearbox disposed on one side of the column, and a second motor fixedly connected to the top of the second gearbox.

[0014] The present invention is further configured such that a worm, a worm wheel, and a gear are provided inside both the first gearbox and the second gearbox. The worm is movably connected inside the first gearbox and the second gearbox via a bearing. The worm wheel meshes with the worm, and the gear is fixedly connected to one side of the worm wheel.

[0015] The present invention is further configured such that one side of the telescopic arm is provided with teeth, and the inside of the cantilever is provided with a moving groove that matches the teeth.

[0016] The present invention is further configured such that the disc fixing component is fixed to the top of the rotary table by magnetic attraction, and the column has a through groove inside.

[0017] The present invention has the following beneficial effects.

[0018] 1. This utility model achieves highly efficient automated centering through two-dimensional movement driven by a motor. The first motor drives the first gearbox, causing the slide plate to move vertically up and down along the guide rail and rack on the column. At the same time, the second motor drives the second gearbox, causing the telescopic arm to move horizontally within the cantilever. The coordinated operation of these two movements allows the sensor installed at the front end of the telescopic arm to be quickly positioned to the required location, thereby assisting the disc fixing component to accurately coincide with the center of the rotary table. This process replaces the traditional centering method that relies on human eyes and manual scribing, reducing the centering error from an uncontrollable error of more than 0.5mm to a precisely controllable range of 0.003mm to 0.1mm, effectively improving centering accuracy and detection efficiency.

[0019] 2. This utility model ensures the stability and safety of equipment operation through an integrated transmission structure and safety sensors. Both the first and second gearboxes employ a combination of worm gears, worm wheels, and gears for transmission. This structure features smooth transmission and good self-locking, effectively guaranteeing the stability of the slide and telescopic arm during movement and stationary positioning, preventing displacement caused by gravity or external forces. Simultaneously, a sensor is installed at the front end of the telescopic arm to detect obstacles in real time during movement, preventing collisions with the rotary table or other equipment. This combination of movement and protection effectively improves the reliability and safety of the tooling structure in complex industrial environments, avoiding equipment damage that may result from misoperation.

[0020] 3. This utility model, through its modular and detachable design and flexible adjustment capabilities, endows the tooling structure with strong versatility and economy. The main components, such as the base and column, guide rail and rack, cantilever and slide, are all connected by bolts or other detachable means. Combined with the vertical and horizontal two-dimensional movement driven by the motor, the tooling structure can quickly adapt to the inspection needs of rotary worktables of different sizes and specifications. This modular design not only simplifies the transportation and on-site installation process, but also allows for flexible movement processes that can complete multiple tasks with one set of equipment. This avoids the necessity of manufacturing specific inspection tools for different worktables, effectively reducing equipment costs and inventory management complexity.

[0021] 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

[0032] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0033] Example 1

[0034] Please see Figures 1-8This utility model is a tooling structure for detecting the accuracy of a rotary worktable, including a rotary worktable 1, a base 2 on one side of the rotary worktable 1, a column 3 on the top of the base 2, a vertical moving component 4 on one side of the column 3, a horizontal moving component 5 on the top of the rotary worktable 1, a power component 6 on one side of the column 3, a sensor 7 on the top of the base 2, and a disc fixing component 8 on the top of the rotary worktable 1.

[0035] As a preferred embodiment of the above: the base 2 and the column 3 form the basic support frame of the tooling, providing a stable reference for the entire system. The vertical moving component 4 is responsible for bearing and driving the horizontal moving component 5 to move vertically along the column 3. The horizontal moving component 5 is responsible for horizontal telescopic movement. Through the cooperation of the vertical moving component 4 and the horizontal moving component 5, the sensor 7 installed at the end of the telescopic arm 52 can be positioned to the required position. The power component 6 serves as the driving source, driving vertical movement through the first motor 62 and the first gearbox 61, and driving horizontal movement through the second motor 64 and the second gearbox 63, realizing automated position adjustment driven by motors, replacing cumbersome manual operation. The sensor 7 is installed at one end of the telescopic arm 52 to detect obstacles and prevent collisions during movement, ensuring operational safety and equipment safety. The disc fixing component 8 serves as the centering reference and is temporarily fixed to the rotary table 1 by magnetic attraction.

[0036] Example 2

[0037] Please see Figures 1-8 Based on embodiment 1, the base 2 has bottom holes at all four corners, and expansion bolts are installed inside the bottom holes. The base 2 and the column 3 both have mounting through holes, and mounting bolts are threaded into the mounting through holes. The vertical moving component 4 includes a guide rail 41 on one side of the column 3, a rack 42 on one side of the column 3, and a slide plate 43 on one side of the column 3. The guide rail 41 and the rack 42 both have fixing holes. The guide rail 41 and the rack 42 are fixedly connected to the same side of the column 3 by bolts. The guide rail 41 and the rack 42 are designed to be parallel and spaced along the axial direction of the column 3. The slide plate 43 has a groove on one side that is compatible with the guide rail 41 and the rack 42.

[0038] As a preferred embodiment of the above: the base 2 is horizontally fixed on the ground by the bottom hole and expansion bolts to ensure that the device is in a stable state. The column 3 is detachable by the installation through hole and installation bolts, which is used to fix the column 3 to the top of the base 2. The vertical moving component 4 is used to drive the horizontal moving component 5 to move up and down.

[0039] Example 3

[0040] Please see Figures 1-8Based on Embodiments 1 and 2, the lateral movement assembly 5 includes a cantilever 51 disposed on one side of the column 3, and a telescopic arm 52 disposed inside the cantilever 51. The power assembly 6 includes a first gearbox 61 disposed on one side of the column 3, a first motor 62 fixedly connected to one side of the first gearbox 61, a second gearbox 63 disposed on one side of the column 3, and a second motor 64 fixedly connected to the top of the second gearbox 63. Both the first gearbox 61 and the second gearbox 63 are provided with a worm, a worm wheel, and a gear inside. The worm is movably connected to the first gear through a bearing. Inside gearbox 61 and the second gearbox 63, the worm gear meshes with the worm, and the gear is fixedly connected to one side of the worm gear. The first gearbox 61 is fixedly connected to one side of the slide plate 43. The gear inside the first gearbox 61 meshes with the rack 42. The telescopic arm 52 is provided with teeth on one side, and the cantilever 51 is provided with a moving groove that matches the teeth. The second gearbox 63 is fixedly connected to one side of the cantilever 51. The gear inside the second gearbox 63 meshes with the teeth on one side of the telescopic arm 52. The disc fixing part 8 is fixed to the top of the rotary table 1 by magnetic attraction. The column 3 is provided with a through groove.

[0041] As a preferred embodiment of the above, the lateral moving component 5 is used to drive the sensor 7 fixed at one end of the telescopic arm 52 to move left and right. In conjunction with the vertical moving component 4, the sensor 7 is adjusted to a suitable position to prevent misoperation, prevent collisions, and ensure work safety. The power component 6 transmits the power of the motor to the vertical moving component 4 and the lateral moving component 5 respectively. The rotational force of the first motor 62 is transmitted to the rack 42 through the gear inside the first gearbox 61, thereby driving the slide plate 43 to move vertically along the guide rail 41. The rotational force of the second motor 64 is transmitted to the horizontal linear motion of the telescopic arm 52 through the gear inside the second gearbox 63, so that the telescopic arm 52 moves laterally inside the cantilever 51. The through groove provides sliding space for the movement of the telescopic arm 52.

[0042] The working principle of this utility model is as follows: Before testing, the base 2 is first installed horizontally and securely on the ground on one side of the rotary worktable 1 through the bottom hole and expansion bolts on the base 2. The disc fixing part 8 is initially placed near the center of the rotary worktable 1 by magnetic attraction. Then, the power component 6 is started, and the first motor 62 drives the first gearbox 61, so that the gear inside it meshes with the rack 42 fixed on the column 3, thereby driving the slide plate 43 fixed with the first gearbox 61 to move vertically up and down along the guide rail 41 on the column 3. This vertical movement adjusts the height position of the entire horizontal movement component 5.

[0043] Then, the second motor 64 starts, driving the second gearbox 63 so that the gear inside it meshes with the teeth on one side of the telescopic arm 52, thereby pushing the telescopic arm 52 to make a horizontal telescopic movement inside the cantilever 51. The sensor 7 installed at the end of the telescopic arm 52 moves accordingly to accurately position and prevent collisions. Through coordinated adjustment in both vertical and horizontal directions, the sensor 7 can be quickly guided to the predetermined position, assisting in achieving high-precision alignment between the disc fixing part 8 and the center of the rotary table 1, laying the foundation for subsequent table accuracy inspection.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
