Description

Technical Field

[0001] This utility model relates to the field of workbench technology, and in particular to a rotary workbench that can automatically reset. Background Technology

[0002] A rotary table is a widely used equipment component in machining, assembly, and testing. Its main function is to enable the workpiece or operating platform to rotate around an axis, facilitating multi-faceted machining, multi-angle assembly, or orientation adjustment of the workpiece. It typically consists of a main structure, a rotary drive mechanism, a limit positioning mechanism, and auxiliary protective components. It features smooth rotation and precise positioning. Some types also integrate an automatic reset function, which can automatically return to the initial position after completing the operation, improving operational efficiency.

[0003] An investigation revealed that a Chinese utility model patent (CN104889751A) discloses a rotary table clamping device and its rotary table. The device includes: an annular brake pad, arranged around the rotary table surface and rotating synchronously with it; and a clamping mechanism mounted on the base of the rotary table for clamping the annular brake pad. This rotary table clamping device places the clamping mechanism outside the rotary table and utilizes the lever principle, along with loading and resetting components, to control the clamping body to clamp or release the annular brake pad that rotates synchronously with the rotary table surface. This type of rotary table clamping device avoids deformation of the rotary table and a decrease in machining accuracy; it also has advantages such as good clamping and locking effect, simple and compact structure, convenient installation and disassembly, and easy maintenance.

[0004] When the user uses the aforementioned patent, the limiting method is relatively simple, making it difficult for the user to form a stable support, which leads to shaking and deviation. Furthermore, the positioning is difficult when assembling the workbench, and the protection effect is not good enough. This will reduce the service life of the equipment, thereby increasing the operation and maintenance costs and frequency.

[0005] Therefore, there is a particular need for a rotary table that can automatically reset. Utility Model Content

[0012] Preferably, the upper surface of the positioning plate has a through-hole positioning opening, and the number of positioning openings is multiple.

[0013] Preferably, the motor is connected to the protective shell via a connecting block, and the connecting block is symmetrically arranged with the vertical center line of the motor as the axis of symmetry.

[0014] Preferably, an upper protective cover is fixedly connected to the outer ring surface of the upper operating platform, and the upper protective cover and the outer ring protective frame are structurally compatible.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

Detailed Implementation

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: an automatically resetting rotary worktable, including a rotary worktable body 1, a docking rod 2 fixedly connected to the bottom surface of the rotary worktable body 1, a positioning plate 4 fixedly connected to the bottom surface of the docking rod 2, and a rotary mechanism 3 installed on the upper surface of the rotary worktable body 1.

[0025] The rotary mechanism 3 includes a limiting support arm 301, which is mounted on the rotary worktable body 1. A limiting insert plate 302 is fixedly connected to the upper surface of the limiting support arm 301. A telescopic rod 303 is fixedly connected to the side surface of the limiting support arm 301. A positioning support insert rod 306 is fixedly connected to the side surface of the telescopic rod 303. A positioning circular collar 307 is limited and engaged on the side surface of the positioning support insert rod 306. An outer protective frame 308 is fixedly connected to the upper surface of the positioning circular collar 307. A mating frame 309 is fixedly connected to the inner ring surface of the protective frame 308. A protective shell 310 is inserted into the inner ring surface of the mating frame 309. A connecting block 311 is fixedly connected to the inner ring surface of the protective shell 310. A motor 312 is fixedly connected to one side of the connecting block 311. An output gear 313 is fixedly sleeved on the top of the output shaft of the motor 312. A transmission gear ring 314 is sleeved on the outer ring surface of the rotary worktable body 1. An upper operating plate 315 is fixedly connected to the upper surface of the transmission gear ring 314.

[0026] Furthermore, a controller 305 is fixedly connected to the upper surface of the limit support arm 301, and the controller 305 is connected to the rotary table body 1 through the limit support arm 301. The controller 305 can achieve precise control of the start and stop of the motor 312, its speed and rotation angle.

[0027] Furthermore, a limiting block 304 is fixedly connected to the side surface of the limiting plate 302, and the limiting block 304 and the limiting support arm 301 are structurally compatible. The limiting block 304 enhances the stability of the connection between the limiting plate 302 and the limiting support arm 301, preventing the limiting plate 302 from becoming loose or shifting during the operation of the worktable, ensuring the reliable limiting effect on the rotary mechanism 3, and preventing the rotation accuracy of the worktable from being affected by component displacement.

[0028] Furthermore, the inner ring surface of the limiting support arm 301 is provided with a first hollow opening 316, and the size of the first hollow opening 316 and the limiting insert plate 302 are matched. The first hollow opening 316 provides a precise installation and positioning space for the limiting insert plate 302, which facilitates the quick assembly of the limiting insert plate 302.

[0029] Furthermore, the upper surface of the positioning plate 4 is provided with a positioning opening 5, and there are multiple positioning openings 5. The multiple positioning openings 5 ​​can be adapted to different installation scenarios. The workbench is firmly installed on the ground or support base by fasteners such as bolts passing through the positioning openings 5. The fixation at multiple points can effectively disperse the impact force generated when the workbench is running, prevent the equipment from shaking, and improve the overall installation stability.

[0030] Furthermore, the motor 312 is connected to the protective shell 310 via a connecting block 311, and the connecting block 311 is symmetrically arranged with the vertical center line of the motor 312 as the axis of symmetry. The symmetrical connecting block 311 can make the motor 312 bear force evenly, reduce the vibration of the motor 312 during operation, and reduce noise.

[0031] Furthermore, an upper protective cover plate 317 is fixedly connected to the outer ring surface of the upper operating platform 315, and the upper protective cover plate 317 and the outer ring protective frame 308 are structurally compatible with each other. The upper protective cover plate 317 and the outer ring protective frame 308 cooperate to form a closed protective structure, thereby providing protection during use.

[0032] Working principle: When the user needs to use a rotary worktable that can automatically reset, the positioning plate 4 connected to the bottom docking rod 2 of the rotary worktable body 1, and the multiple positioning openings 5 ​​on the positioning plate 4, are used to fix the entire worktable to the designated support base with bolts and other fasteners, thus completing the installation and stabilization of the equipment. The operator inputs the rotation or reset command through the controller 305 fixed on the upper surface of the limit support arm 301. The controller 305 obtains the basic status information of the equipment through the limit support arm 301 connected to the rotary worktable body 1, starts the running program, and drives the motor 312 fixed in the protective shell 310 through the symmetrical connecting block 311 to rotate. The output gear 313 at the top of the output shaft of the motor 312 rotates accordingly. The output gear 313 meshes with the transmission gear ring 314 that is limited and sleeved on the outer ring of the rotary worktable body 1, driving the upper operating plate 315 on the upper surface of the transmission gear ring 314 to rotate.

[0033] During the rotation, the telescopic rod 303 on the side of the limiting support arm 301 drives the positioning support rod 306 to slide within the positioning ring 307. This, combined with the fitting structure of the limiting block 304 on the side of the upper positioning plate 302 and the limiting support arm 301, as well as the positioning effect of the first hollow opening 316 on the inner ring of the limiting support arm 301 on the limiting plate 302, achieves multi-dimensional limiting of the rotating mechanism 3, ensuring that the upper operating platform 315 rotates smoothly and accurately. The upper protective cover 317 on the outer ring of the upper operating platform 315 fits tightly with the outer ring protective frame 308. The outer ring protective frame 308 is connected to the protective shell 310 through the docking frame 309, forming a closed protective space to prevent external impurities from entering the protective shell 310 and damaging core components such as the motor 312 and the output gear 313.

[0034] When a reset is required, the controller 305 issues a reset command, the motor 312 rotates in reverse, and through the meshing of the output gear 313 and the transmission gear ring 314, it drives the upper operating platform 315 to rotate in reverse until it returns to the initial set position. After receiving the position feedback signal, the controller 305 stops the motor 312 and completes the automatic reset process.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
