Abstract
Description
Technical Field
[0001] This utility model relates to the field of tooling and fixture technology, specifically to a universal floating plug device. Background Technology
[0002] With the rapid development of automotive technology, the demand for compressors, as the core component of automotive air conditioning systems, is increasing year by year. As the most crucial component of the compressor, the performance of the electronic control valve determines the overall product quality of the air conditioning system, making quality control of the electronic control valve essential. Therefore, after assembly, the performance parameters of the electronic control valve need to be tested. With the increasing level of automation, automotive component manufacturers currently mainly use automated testing equipment for testing. However, the plugs in existing testing equipment are generally of a fixed structure. Due to allowable deviations in manufacturing processes, the coil plug of the electronic control valve often cannot be properly aligned with the main plug, easily damaging the coil pins. It is necessary to optimize and improve the rigid plug to allow for vertical and horizontal floating, which can compensate for errors in the parts themselves and the assembly process, achieving a stable and efficient automated testing connection solution, thereby improving the success rate and accuracy of testing.
[0003] Currently available floating test devices for other industries, such as the German Schunk compensator, are very expensive and often have very complex structures. These structures are difficult for general automotive parts manufacturers to accept and cannot be applied to large-scale practical applications. Utility Model Content
[0004] To address the aforementioned technical shortcomings, the present invention aims to provide a universal floating plug device that allows for floating in all directions (up, down, left, and right) to compensate for errors in the components and assembly process. This universal floating plug device is suitable for automated assembly and has high positioning accuracy.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a universal floating plug device, including: a slide rail mounting base, a linear guide rail, a fixing plate, a flat-head screw, a connecting plate, a cylinder, a floating connecting plate and a plug fixing assembly;
[0006] The linear guide is fixed to the slide rail mounting base, the fixing plate is fixed to the linear guide, the flat head screw is fixed to the fixing plate, the connecting plate is fixed to the fixing plate, the cylinder is fixed under the slide rail mounting base, one end of the floating connecting plate cooperates with the cylinder, and the other end is locked to the fixing plate, and the plug fixing assembly is assembled between the fixing plate and the connecting plate.
[0007] Furthermore, a gap is left between the plug fixing assembly and the connecting plate.
[0008] Furthermore, the plug fixing assembly includes a floating mechanism and a swing mechanism mounted on the floating mechanism.
[0009] Furthermore, the floating mechanism includes a plug fixing block, a torsion spring fixing post, a torsion spring, a second fastener, and a torsion spring limiting post;
[0010] The torsion spring fixing post is fixed to the plug fixing block by the second fastener and is interference-fitted with the plug fixing block. The torsion spring is mounted on the torsion spring fixing post and contacts the torsion spring limiting post to ensure floating movement of ±5° to the left and right.
[0011] Furthermore, the swing mechanism includes: a plug clamp, a first fastener, a plug, and a ball plunger;
[0012] The plug clamp uses a first fastener to fix the plug to the plug fixing block, and the ball plunger is installed in the torsion spring fixing column with the ball facing down to achieve left and right swing.
[0013] Furthermore, the first fastener is an M3×12 screw, and the second fastener is an M3×6 screw.

[0025] 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. Example
[0026] like Figure 1 and Figure 2 As shown, this embodiment provides a universal floating plug device, including: a slide rail mounting base 1, a linear guide rail 2, a fixing plate 3, a flat-head screw 4, a connecting plate 5, a cylinder 6, a floating connecting plate 7, and a plug fixing assembly 8; the linear guide rail 2 is fixed on the slide rail mounting base 1, the fixing plate 3 is fixed on the linear guide rail 2, the flat-head screw is fixed on the fixing plate 3, the connecting plate 5 is fixed on the fixing plate 3, the cylinder 6 is fixed below the slide rail mounting base, one end of the floating connecting plate cooperates with the cylinder 6, and the other end is locked onto the fixing plate 3. The plug fixing assembly 8 is assembled between the fixing plate 3 and the connecting plate 5. The floating structure can achieve a left-right floating of 5° and a vertical floating of 0.2mm.
[0027] like Figure 2 As shown, the plug fixing assembly 8 structure includes a floating mechanism 81 and a swing mechanism 82 mounted on the floating mechanism 81.
[0028] The plug includes a plug fixing block 811, a torsion spring fixing post 812, a torsion spring 813, a plug clamping block 821, a first fastener 822, a second fastener 814, a ball plunger 824, a plug 823, and a torsion spring limiting post 815. The torsion spring fixing post 812 is interference-fitted with the plug fixing block 811. The torsion spring 813 is mounted on the torsion spring fixing post 812 and contacts the torsion spring limiting post 815 to ensure a floating movement of ±5° to the left and right. The plug clamping block 821 uses an M3×12 screw as the first fastener 822 to fix the plug 823 to the plug fixing block 811. The ball plunger 824 is installed in the torsion spring fixing post 812 with the ball head facing down to achieve left and right swinging. The plug clamping block 821 fixes the plug 823 to the plug fixing block 811 through the first fastener 822. The torsion spring fixing post 812 is fixed to the plug fixing block 811 through an M3×6 screw as the second fastener 814.
[0029] The working principle of this utility model is as follows: In actual use, after the universal floating plug device is debugged, the cylinder starts to move, driving the plug fixing component 8 to move. The linear guide rail 2 ensures the high-precision linear movement of the plug fixing component 8. The plug 823 of the fixing component 8 is inserted into the product. Due to the error of the product parts themselves and the assembly process, the plug 823 is not concentric with the center line of the coil plug of the product. At this time, the torsion spring fixing post 812, the torsion spring 813 and the torsion spring limiting post 815 cooperate with each other to achieve a left and right ±5° floating of the plug. Since there is a 0.2mm gap between the connecting plate 5 and the plug fixing component 8, a vertical floating of 0.2mm can be achieved to compensate for the error and ensure high-precision insertion and straight-through. After the test is completed, when the cylinder 6 returns to the initial state, the torsion spring 813 automatically resets, and the plug fixing component 8 returns to the initial state. The testing requirements of different products can be met by changing the plug.
[0030] The universal floating plug device proposed in this utility model has the following advantages: 1) It is suitable for automated testing equipment and can freely and quickly switch test plugs according to different products; 2) The floating structure increases the test pass rate from 90% to 99%, which is a significant improvement; 3) The floating structure can effectively protect the product and improve testing efficiency; 4) The structure is simple, effectively saving costs and requiring less equipment investment.
[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
