Description

Technical Field

[0001] This utility model relates to the field of rotating equipment technology, and in particular to a drive mechanism and a turntable device. Background Technology

[0002] Automated turntables, widely used in automated production lines, typically employ servo motors and frequency converters. This rotation method offers high control precision and stable quality, but it is also more expensive. According to a 2022 research report on the new energy vehicle drive motor industry, the prices of key raw materials for servo motors, such as electrical steel, permanent magnets, and flat copper wire, rose sharply in 2021, increasing material costs. In addition to the motor itself, the cost of couplings supporting the load and additional bearings, as well as the design and engineering costs of integrating these components, must be considered. Furthermore, servo motors require more complex control systems and feedback mechanisms to achieve precise control, which may increase response time. Utility Model Content

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0004] The purpose of this invention is to provide a driving mechanism that addresses the drawback of high operating costs in existing turntable equipment.

[0008] As a preferred embodiment of the drive mechanism of this utility model, the working platform is provided with mechanical limit blocks around its perimeter to prevent the workpiece from falling.

[0009] In a preferred embodiment of the drive mechanism of this utility model, the drive rack and the mounting slider are detachably connected.

[0010] As a preferred embodiment of the driving mechanism of this utility model, a guide member is provided between the mounting slider and the loading and unloading plate to improve the stability of the movement of the mounting slider. The guide member includes a guide block fixedly mounted on the loading and unloading plate, and a guide groove for the guide block to slide is provided on the mounting slider near the guide block.

[0011] In a preferred embodiment of the drive mechanism of this utility model, a support member for supporting the rotating platform is provided between the rotating platform and the mounting platform. The support member includes a support seat fixedly installed on the mounting platform, and a support ball is provided between the support seat and the rotating platform.

[0012] In a preferred embodiment of the drive mechanism of this utility model, the supporting ball is in a rolling connection with the supporting seat.

[0013] The beneficial effects of the drive mechanism of this utility model are as follows: through the mechanical cooperation between components such as the drive cylinder, the mounting slider and the drive rack, the effect of controlling the rotation of the work platform is achieved. At the same time, since the energy medium of the drive cylinder is air, the drive energy required by the automatic equipment can be generated at low cost. This is an easily obtainable and low-cost resource. In addition, the drive cylinder is small in size and has high thrust.

[0027] 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.

[0028] 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.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0030] Example 1, referring to Figures 1-6 This is the first embodiment of the present invention, which provides a drive mechanism including a mounting assembly 200, comprising a mounting platform 101 and platform supports 102 fixedly mounted on the bottom of the mounting platform 101. The mounting platform 101 is mainly designed to support other parts and provide a better platform for the linkage between various components. The drive assembly 200 includes a loading / unloading plate 201 mounted on the mounting platform 101, on which a drive cylinder 202 and a mounting slider 203 are mounted, and the drive cylinder 202 is kinetically connected to the mounting slider 203. The drive cylinder 202 provides a power source for the operation of the drive assembly 200. Furthermore, the energy medium for the drive cylinder 202 is air, a readily available and low-cost resource, thus generating the drive energy required for automated equipment at low cost. Simultaneously, the drive cylinder 202 is compact and has high thrust, allowing for installation in a compact and limited space while maintaining high thrust output compared to a servo motor, which helps reduce the overall cost of the equipment.

[0031] Furthermore, a drive rack 205 is provided on the side of the mounting slider 203 away from the drive cylinder 202. The drive rack 205 is externally meshed with a drive gear 206 rotatably connected to the mounting platform 101. A rotating platform 207, coaxially fixed with the drive gear 206, is provided on the side of the mounting platform 101 away from the drive cylinder 202. During rotation, the drive cylinder 202 is started first. Utilizing the transmission connection between the drive cylinder 202 and the mounting slider 203, the drive rack 205 mounted on the mounting slider 203 is driven to move synchronously. Since the drive rack 205 meshes with the drive gear 206, the movement of the drive rack 205 will drive the drive gear 206 to rotate, thereby driving the rotating platform 207, coaxially fixed with it, to rotate, thus achieving the purpose of controlling the rotation of the working platform 208.

[0032] Furthermore, a work platform 208 for holding workpieces is detachably installed on the rotating platform 207. Because the rotating platform 207 and the work platform 208 are detachably connected, in actual use, operators can flexibly install various fixtures, tooling, and material racks as needed, expanding the applicability of the turntable.

[0033] Furthermore, mechanical limit blocks 210 are provided around the work platform 208 to prevent workpieces from falling. Since the work platform 208 generates centrifugal force when it rotates, the workpiece placed on it may move in the planar direction. Therefore, in this embodiment, mechanical limit blocks 210 are provided around the work platform 208 to restrict the movement of the workpiece, prevent it from falling, and ensure the normal operation of the processing.

[0034] In use, the mechanical cooperation between components such as the drive cylinder 202, the mounting slider 203, and the drive rack 205 achieves the effect of controlling the rotation of the work platform 208. At the same time, since the energy medium of the drive cylinder 202 is air, the driving energy required by the automatic equipment can be generated at low cost. This is an easily accessible and low-cost resource. In addition, the drive cylinder 202 is small in size and has high thrust. Compared with servo motors, it can be installed in a compact and limited space while maintaining high thrust output and response speed, which helps to reduce the overall cost of the equipment.

[0035] Example 2, refer to Figures 1-6 This is the second embodiment of the present invention. Unlike the previous embodiment, it also includes a detachable connection between the drive rack 205 and the mounting slider 203. During long-term operation, the teeth on the drive rack 205 will wear to a certain extent, thus failing to fully mesh with the drive gear 206, thereby reducing the response speed of the drive assembly 200. Therefore, in this embodiment, the drive rack 205 and the mounting slider 203 are detachably mounted together, allowing operators to replace the drive rack 205 according to the wear condition of the teeth, ensuring the response speed of the drive assembly 200.

[0036] Furthermore, a guide member 204 is provided between the mounting slider 203 and the loading / unloading plate 201 to improve the smoothness of the movement of the mounting slider 203. The guide member 204 includes a guide block 204a fixedly mounted on the loading / unloading plate 201, and a guide groove 204b is provided on the mounting slider 203 near the guide block 204a for the guide block 204a to slide. The arrangement of the guide block 204a and the guide groove 204b provides guidance for the operation of the mounting slider 203, preventing it from deviating during movement, and further improving the meshing stability between the drive rack 205 and the drive gear 206.

[0037] Furthermore, a support member 209 for supporting the rotating platform 207 is provided between the rotating platform 207 and the mounting platform 101. The support member 209 includes a support seat 209a fixedly mounted on the mounting platform 101, and a support ball bearing 209b is provided between the support seat 209a and the rotating platform 207. Figure 4 As shown, the support members 209 are evenly distributed between the mounting platform 101 and the rotating platform 207, ensuring the stability of the rotation of the rotating platform 207.

[0038] Furthermore, the support ball 209b is in a rolling connection with the support base 209a. Because of this rolling connection, the sliding friction between the rotating platform 207 and the support member 209 is converted into rolling friction, thereby reducing wear between components and improving their service life.

[0039] In use, the guide block 204a and guide groove 204b provide guidance for the operation of the mounting slider 203, further improving the meshing stability between the drive rack 205 and the drive gear 206. In addition, the connection between the support ball 209b and the support base 209a converts the sliding friction between the rotating platform 207 and the support member 209 into rolling friction, reducing wear between components and improving the service life of related components.

[0040] Example 3, referring to Figure 7 and Figure 8 This is the third embodiment of the present invention, which further provides a turntable device. It includes a linkage assembly 300, comprising a linkage member 301 fixedly mounted on the output shaft of the drive cylinder 202 and a linkage block 302 fixedly mounted on the mounting slider 203. The linkage member 301 and the linkage block 302 are rotatably connected, and a linkage rod 303 is provided at the pivot point of the linkage member 301 and the linkage block 302. Due to the characteristics of the drive cylinder 202, the travel direction of the drive rack 205 must be consistent with the output direction of the drive cylinder 202. This limits the scope of application of the device and is not conducive to installation in different positions. Therefore, in this embodiment, the linkage assembly 300 allows the output end of the drive cylinder 202 to be movably connected to the mounting slider 203, so that even if the travel direction of the mounting slider 203 intersects with the output direction of the drive cylinder 202, the drive cylinder 202 can still drive the mounting slider 203.

[0041] Furthermore, both ends of the linkage rod 303 are connected to insert rods 304. The insertion rods 304 allow the operator to disassemble the linkage assembly 300 as needed, facilitating the replacement of faulty components inside the linkage assembly 300.

[0042] In use, the linkage component 300 enables the output end of the drive cylinder 202 to be movably connected to the mounting slider 203. This allows the drive cylinder 202 to still drive the mounting slider 203 even if the direction of travel of the mounting slider 203 is intersected with the output direction of the drive cylinder 202, thereby expanding the applicability of the equipment and facilitating its installation in different locations.
