Description

Technical Field

[0001] This utility model relates to the field of automotive bushing production equipment, and in particular to an automatic assembly and testing device for subframe bushings. Background Technology

[0002] The subframe bushing is a component that connects the vehicle chassis parts. Its main function is to connect the subframe to the body, reduce vibration, and improve ride comfort.

[0003] In the production process, the existing subframe bushing assembly and inspection process mainly relies on manual operation. This not only leads to high labor intensity and fatigue for workers, thus affecting work efficiency and assembly quality, but also makes it difficult to effectively control quality due to the unavoidable errors in manual operation. Furthermore, once a product problem occurs, the poor traceability of manual operation makes it difficult to quickly and accurately locate the source of the problem, which brings great difficulties to subsequent quality improvement and traceability. Utility Model Content

[0004] The purpose of this invention is to provide an automatic assembly and testing device for subframe bushings to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: it includes a support frame, a base is provided on one side of the support frame, a pressing assembly is provided on the base, a detection assembly is provided on the base on one side of the pressing assembly, and a bushing feeder is provided on one side of the base.

[0006] As a preferred embodiment of this utility model, an end cap feeding conveyor is provided on one side of the support frame, and an industrial robot is provided at the tail of the end cap feeding conveyor.

[0007] In a preferred embodiment of this utility model, the pressing assembly includes a linear motor mounted on a base, a pressing worktable mounted on the linear motor, a mounting frame mounted on the base, a hydraulic cylinder mounted on the mounting frame, a telescopic rod of the hydraulic cylinder passing through the mounting frame, a pressure plate at the bottom of the telescopic rod of the hydraulic cylinder, a pair of lifting guide columns on both sides of the bottom of the mounting frame, and guide column sleeves on the pressure plate corresponding to the positions of the lifting guide columns.

[0008] As a preferred embodiment of this utility model, the detection component includes a conveying mechanism disposed on a base, a degumming detection mechanism disposed on one side of the base, a bushing orientation identification mechanism disposed on the side of the degumming detection mechanism away from the bushing feeder, a bushing height measuring mechanism disposed on the side of the mounting bracket away from the bushing orientation identification mechanism, and a bushing inner hole passage detection mechanism disposed on the side of the bushing height measuring mechanism away from the bushing orientation identification mechanism.

[0009] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0010] This invention features a pressing assembly. An industrial robot picks up the end cap and places it on the pressing table. A linear motor then quickly and accurately moves the pressing table directly under the pressure plate, automating the loading of the end cap. Next, a transport mechanism moves the bushing to the pressing table and applies pressure via a hydraulic cylinder, achieving efficient and stable pressing of the bushing and end cap. The combined use of lifting guide pillars and guide pillar bushings enhances stability and verticality control during the pressing process, effectively preventing quality problems caused by pressing deviations.

[0011] This invention achieves comprehensive, multi-indicator automated testing of bushings by integrating multiple automated testing and handling mechanisms with a set of testing components. Simultaneously, all related tests are monitored, reducing product quality risks, improving quality traceability, providing a data foundation for process improvement, and offering a reference for quality enhancement. Specifically, the degumming detection mechanism can promptly detect degumming on the bushing surface, ensuring the basic quality of the bushing. The bushing orientation identification mechanism accurately identifies the placement direction of the bushing, providing correct alignment information for subsequent pressing operations. The bushing height measurement mechanism and the bushing inner hole clearance detection mechanism measure the height and inner hole clearance of the bushing, respectively, further ensuring the structural integrity of the bushing and its compliance with design requirements. Furthermore, the entire equipment achieves automated feeding of end caps and bushings through the cooperation of an end cap feeding conveyor, industrial robot, bushing feeding machine, and handling mechanism. Combined with the pressing and testing components, it realizes a comprehensive automated testing process, which not only improves testing efficiency and accuracy but also effectively reduces errors and costs associated with manual testing, providing strong assurance for product quality.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0017] like Figures 1-3 As shown, the present invention proposes an automatic assembly and testing device for subframe bushings, which includes a support frame 1, a base 3 on one side of the support frame 1, a pressing component 2 on the base 3, a testing component 5 on the base 3 on one side of the pressing component 2, and a bushing feeder 4 on one side of the base 3. The bushing feeder 4 automatically provides bushings so that the conveying mechanism 53 can transport them to the testing component 5 and the pressing component 2.

[0018] An end cap feeding conveyor 11 is provided on one side of the support frame 1. The end cap feeding conveyor 11 transports the end caps to the designated work station so that the industrial robot 12 can pick them up and handle them. An industrial robot 12 is provided at the tail of the end cap feeding conveyor 11. The industrial robot 12 picks up the end caps from the end cap feeding conveyor 11 and accurately places them on the pressing workbench 22 to realize automated operation.

[0019] The pressing assembly 2 includes a linear motor 27 mounted on a base 3. The linear motor 27 drives the pressing worktable 22 to move precisely, transporting the end cap directly below the pressing plate 24. The pressing worktable 22 is mounted on the linear motor 27 and is used to place the end cap and bushing. A mounting frame 21 is mounted on the base 3, providing a mounting base for the hydraulic cylinder 23. The hydraulic cylinder 23 is mounted on the mounting frame 21, and its telescopic rod passes through the mounting frame 21. A pressing plate 24 is mounted at the bottom of the telescopic rod of the hydraulic cylinder 23. The hydraulic cylinder 23 provides the pressure required for pressing and pushes the pressing plate 24 through the telescopic rod for pressing. The pressing plate 24 acts directly on the bushing, pressing it into the end cap. A pair of lifting guide columns 26 are mounted on both sides of the bottom of the mounting frame 21. Guide column sleeves 25 are mounted on the pressing plate 24 at positions corresponding to the lifting guide columns 26. The combined use of the lifting guide columns 26 and the guide column sleeves 25 ensures the vertical movement of the pressing plate 24 during the pressing process and maintains the stability of the pressing.

[0020] The inspection component 5 includes a conveying mechanism 53 mounted on the base 3. The conveying mechanism 53 is responsible for conveying the bushing between various inspection mechanisms to achieve automated assembly line operation. A degumming inspection mechanism 51 is mounted on one side of the base 3. The degumming inspection mechanism 51 detects whether there is degumming on the surface of the bushing to ensure the quality of the bushing. A bushing orientation identification mechanism 52 is mounted on the side of the degumming inspection mechanism 51 away from the bushing feeder 4. The bushing orientation identification mechanism 52 identifies the placement direction of the bushing to ensure correct alignment during pressing. A bushing height measuring mechanism 55 is mounted on the side of the mounting bracket 21 away from the bushing orientation identification mechanism 52. The bushing height measuring mechanism 55 measures the height of the bushing to determine whether it meets the design requirements. A bushing inner hole clearance inspection mechanism 54 is mounted on the side of the bushing height measuring mechanism 55 away from the bushing orientation identification mechanism 52. The bushing inner hole clearance inspection mechanism 54 detects the clearance of the bushing inner hole to ensure that the internal structure of the bushing is intact and meets the standards.

[0021] In operation, the operator first places the end cap on the end cap feeding conveyor 11. The end cap is then transported to the designated position by the end cap feeding conveyor 11. The industrial robot 12 picks up the end cap and accurately places it on the pressing table 22. The linear motor 27 moves the pressing table 22 directly under the pressure plate 24. At the same time, the operator places the bushing on the bushing feeding machine 4. The conveying mechanism 53 transports the bushing to the degumming detection mechanism 51 for degumming detection to ensure the quality of the bushing. Subsequently, the bushing is transported by the conveying mechanism 53 to the bushing orientation identification mechanism 5. 2. Orientation identification is performed to ensure correct alignment during pressing. Then, the bushing is transported by the conveying mechanism 53 to the pressing worktable 22 for assembly with the end cap. The hydraulic cylinder 23 of the pressing component 2 provides pressure, and the bushing is pressed into the end cap through the pressure plate 24. After assembly, the conveying mechanism 53 transports the assembled bushing and end cap to the bushing height measuring mechanism 55 to measure whether its height is qualified. Finally, the bushing is transported by the conveying mechanism 53 to the bushing inner hole clearance detection mechanism 54 for inner hole clearance detection. The whole equipment realizes automated operation, which improves production efficiency and product quality.
