Description

An assembly table structure Technical Field

[0001] This utility model relates to the field of assembly table technology, and specifically to an assembly table structure. Background Technology

[0002] In the automated assembly process of conceptual models, multiple automated devices and components need to work together. The assembly table is an indispensable part of the automated assembly of conceptual models. The assembly table can fix the components in preset positions so that the robotic arm can accurately clamp them and complete the automated assembly.

[0003] The workbench surface is made of spliced ​​aluminum alloy profiles, while the assembly table is installed and fixed to the workbench by bolt connection. In the process of using the existing technology, the inventor found that although the bolt connection method is simple and effective, the bolts fixing the assembly table are prone to loosening due to vibration after long-term use, which affects the fixing strength of the assembly table. Summary of the Invention

[0004] Based on the above description, this utility model provides an assembly table structure to solve the problem that the bolts used for fixing existing assembly tables are prone to loosening due to vibration, which affects the fixing strength of the assembly table.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An assembly table structure includes a table body, and support parts that are inserted into the worktable are provided at the four corners of the table body. The outer side of the support part is threadedly connected to a threaded sleeve that fits against the worktable for locking and fixing. An adjustable positioning ring is installed on the outer side of the support part. A return spring is installed between the threaded sleeve and the positioning ring. The return spring reinforces the threaded sleeve by compression and rebound.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the support includes a first column, a second column, a cam, and a threaded groove. The first column is fixedly connected to a corner of the platform surface, and the second column is integrally formed at the center of the end of the first column away from the platform. The diameter of the second column is smaller than the diameter of the first column.

[0008] Furthermore, the cam is fixedly connected to the center of the second column at the end away from the platform, and the threaded groove is opened on the outer side of the second column at the end away from the platform.

[0009] Furthermore, the first column has an insertion hole at the end away from the platform. The insertion hole is located on the outside of the second column and is distributed in a ring at equal intervals with the center of the second column as the center point. The depths of the multiple insertion holes are different.

[0010] Furthermore, the positioning ring is inserted into the outside of the second column, and a plug is fixedly connected to one end of the positioning ring near the platform, the plug being inserted into the plug hole.

[0011] Furthermore, the threaded sleeve is threadedly connected to the threaded groove, and a rubber pad is fixedly connected to the end of the threaded sleeve away from the platform.

[0012] Furthermore, a collar is rotatably connected to one end of the positioning ring near the threaded sleeve, and the return spring is inserted into the outside of the first column and fixedly connected between the two ends of the collar and the threaded sleeve that are close to each other.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0014] This invention utilizes a positioning ring that is assembled with a socket, in conjunction with a return spring. Due to the varying depths of the sockets, the positioning ring can be combined with sockets of different depths. By adjusting the distance the positioning ring extends toward the threaded sleeve, the compression strength of the return spring is changed, allowing the return spring to generate different magnitudes of rebound force applied to the threaded sleeve. This reinforces the threaded sleeve, increases the connection strength between the threaded sleeve and the worktable, and reduces the impact of vibration on the threaded sleeve.

[0020] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0022] Please refer to Figures 1-3. An assembly table structure of this utility model includes a table body 1. Support parts 2 are provided at the four corners of the table body 1 to be inserted into the workbench. Threaded sleeves 6 are threadedly connected to the outer side of the support parts 2 to fit against the workbench for locking and fixing. An adjustable positioning ring 4 is installed on the outer side of the support parts 2. A return spring 7 is installed between the threaded sleeve 6 and the positioning ring 4. The return spring 7 reinforces the threaded sleeve 6 by compression and rebound.

[0023] Please refer to Figure 2. The support part 2 includes a first column 21, a second column 22, a cam 23, and a threaded groove 24. The first column 21 is fixedly connected to a corner of the platform 1. The second column 22 is integrally formed at the center of the end of the first column 21 away from the platform 1. The diameter of the second column 22 is smaller than the diameter of the first column 21. The difference in diameter between the first column 21 and the second column 22 forms a stepped support, which enhances the bending resistance while reducing material costs. Furthermore, the first column 21 and the second column 22 are integrally formed. The design reduces errors caused by welding or assembly, and improves the overall structural strength of the support part 2. The cam 23 is fixedly connected to the center of the second column 22 away from the platform 1. The threaded groove 24 is opened on the outer side of the second column 22 away from the platform 1. The surface of the aluminum alloy profile will be provided with grooves. When the aluminum alloy is spliced ​​to form a workbench, the grooves on the surface of the aluminum alloy profile will be displayed on the workbench surface at equal intervals. The design of the cam 23 enables the support part 2 to directly cooperate with the workbench to form a plug-in combination, which facilitates the installation of the assembly table.

[0024] Please refer to Figure 2. The first column 21 has an insertion hole 3 at the end away from the platform 1. The insertion holes 3 are located on the outside of the second column 22 and are distributed in a ring at equal intervals with the center of the second column 22 as the center point. The depths of the multiple insertion holes 3 are different. The positioning ring 4 is inserted into the outside of the second column 22. The end of the positioning ring 4 near the platform 1 is fixedly connected to the insertion rod 41. The insertion rod 41 is inserted into the insertion hole 3. The ring-shaped and equally spaced insertion holes 3, combined with the design of different depths, allow the positioning ring 4 to be inserted and fixed at different heights through the insertion rod 41, and to apply different pressures to the return spring 7. The return spring 7 can generate different magnitudes of rebound force to act on the locking reinforcement formed between the threaded sleeve 6 and the worktable, adapting to diverse assembly needs.

[0025] Please refer to Figure 1. The threaded sleeve 6 is threadedly connected to the threaded groove 24. A rubber pad 8 is fixedly connected to the end of the threaded sleeve 6 away from the platform 1. The threaded sleeve 6 moves towards the worktable by rotation on the outside of the threaded groove 24 until the rubber pad 8 is completely in contact with the worktable and cannot move. After that, the threaded sleeve 6 is fixed on the outside of the threaded groove 24 and cooperates with the worktable to form a locking fixation, thus completing the installation of the assembly table. The operation method is the same as the bolt installation method. The rubber pad 8 increases the friction with the worktable and at the same time buffers vibration and impact, strengthening the locking fixation effect of the threaded sleeve 6.

[0026] Please refer to Figure 1. The end of the positioning ring 4 near the threaded sleeve 6 is rotatably connected to the collar 5. The return spring 7 is inserted into the outside of the first column 21 and fixedly connected between the two ends of the collar 5 and the threaded sleeve 6 that are close to each other. The setting of the collar 5 allows the return spring 7 to rotate synchronously through the collar 5 when the threaded sleeve 6 rotates to fit against the worktable for locking. There will be no structural conflict between the threaded sleeve 6, the return spring 7 and the positioning ring 4. At the same time, when the positioning ring 4 rotates to be inserted into different connectors, it is connected by the rotation of the collar 5. The positioning ring 4 will not drive the return spring 7 to rotate and conflict with the threaded sleeve 6.
