Description

Technical Field

[0001] This utility model relates to the technical field of width detection and early warning devices, and more specifically, to an online width detection and early warning fixture. Background Technology

[0002] In the manufacturing process of new energy vehicles, the connection process of the chassis plate plays a crucial role in the performance and safety of the entire vehicle. Among them, friction welding, as an efficient and reliable connection technology, is widely used in the welding of chassis plate components.

[0003] For friction welding, parameters such as heat input, welding pressure, and welding speed all affect the width of the welded part. For example, excessive heat input may cause excessive deformation of the metal at the weld, resulting in a width exceeding the design requirements; while insufficient welding pressure or excessive welding speed may cause incomplete welding, affecting the uniformity of the width. These problems are particularly evident when welding multiple base plates.

[0004] Traditional methods for inspecting base plate width rely heavily on manual sampling. During mass production on the production line, quality inspectors use tools such as gauges and gauges to sample and measure finished products. This method has many drawbacks: firstly, the sampling rate is limited, making it difficult to fully cover every product; secondly, the inspection is delayed, and by the time a problem is discovered, multiple batches of products have often already been produced, resulting in a significant waste of manpower, resources, and time, and seriously hindering the improvement of production efficiency and the stable control of quality.

Detailed Implementation

[0026] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0027] Example

[0028] Please refer to Figures 1-7 This embodiment provides an online width detection and early warning fixture, including a base 2. Multiple clamping devices 66 and displacement detection devices 77 are spaced apart on the top of the base 2. The displacement detection device 77 includes a fixed seat 3 on the top of the base 2 and a limiting push plate 4 slidably mounted on the fixed seat 3 in a horizontal direction. The base 2 is equipped with a displacement sensor 5, the telescopic end of which abuts against the limiting push plate 4. In this embodiment, the displacement sensor 5 uses an existing product, preferably a spring-reset series displacement sensor. By abutting against the limiting push plate 4 with the telescopic end of the displacement sensor 5, the movement distance of the limiting push plate 4 can be detected in real time. The displacement sensor 5 can be connected to a display screen, computer, or other terminal for real-time display of the displacement data detected by the displacement sensor 5, thus facilitating real-time viewing by operators.

[0029] In actual use, such as Figure 1 As shown, multiple clamping devices 66 and displacement detection devices 77 are spaced apart on the top of the base 2. Since the car floor 1 is generally rectangular, the multiple clamping devices 66 of this application can be distributed along the rectangle. The car floor 1 whose width needs to be detected is placed on the top of the base 2, and then the car floor 1 is clamped and fixed to the top of the base 2 by the various clamping devices 66. In this embodiment, the displacement detection devices 77 are mainly distributed on one side of the rectangular structure. After the car floor 1 is installed and fixed, the limiting push plate 4 is moved and tightly abutted against the side of the car floor 1, so that the displacement distance moved by the displacement sensor 5 can be detected. By comparing with the standard distance moved by the displacement sensor 5, the distance tolerance of the displacement sensor 5 can be obtained, so that parts with accumulated tolerance exceeding the tolerance can be screened out, avoiding process scrap.

[0030] The online width detection and early warning fixture provided in this application enables real-time feedback of width data during the production process to operators or automated control systems. Once a dimensional deviation is detected, the vehicle floorboard can be immediately adjusted or replaced to ensure the assembly dimensions meet the drawing requirements.

[0031] Compared to traditional manual sampling or finished product measurement methods, online measurement fixtures can perform measurements automatically and continuously, significantly reducing the workload and time required for manual inspection. This allows operators to focus more on other key production processes, while also accelerating the overall production flow.

[0032] This tooling can accumulate a large amount of measurement data, enabling in-depth analysis of the production process and identification of bottlenecks and potential problems that may affect the width of the car chassis. For example, by analyzing the data and discovering a large deviation in the width dimension within a certain period, combined with the production records at that time, it can be determined whether the cause is insufficient equipment maintenance or deviation in the dimensions of the incoming materials. This allows for targeted optimization of the production process and improvement of overall production efficiency.

[0033] The online width detection and early warning fixture provided in this application can be seamlessly integrated into the production line and linked with the welding equipment. Measurement is initiated immediately upon completion of the welding process or at a specific node in the welding process, quickly acquiring width data and feeding it back to the control system in real time. This allows operators to promptly monitor product quality. If the dimensional deviation exceeds the set threshold, the production line can quickly respond with adjustments or alarm prompts.

[0034] The overall layout is compact and reasonable, making efficient use of limited production space and reducing obstacles to the smoothness of the production line; the mechanical transmission components adopt a low-friction, high-response design to ensure accurate sensor positioning and rapid measurement, thereby improving production efficiency.

[0035] The displacement detection device 77 and the clamping device 66 are flexible and can be adapted to different models and sizes of new energy vehicle base plate tooling. By adjusting the installation position of the displacement detection device 77 and the clamping device 66 on the base 2, the measurement range and position can be easily changed to meet diverse production needs and reduce the frequency and cost of tooling replacement.

[0036] like Figures 1-4As shown, in some embodiments, a sliding push rod 6 is slidably mounted on the fixed base 3 in the horizontal direction. The sliding push rod 6 passes through the fixed base 3, and a limiting push plate 4 is connected to one end of the sliding push rod 6. A return spring 7 is sleeved on the sliding push rod 6, and the fixed base 3 is located between the return spring 7 and the limiting push plate 4. A limiting stop block 8 is provided on the sliding push rod 6, and one end of the return spring 7 abuts against the limiting stop block 8, while the other end of the return spring 7 abuts against the fixed base 3. A longitudinal cylinder 9 is provided on the fixed base 3, and a push block 10 is provided on the extension end of the longitudinal cylinder 9. The side of the push block 10 near the limiting push plate 4 is a first inclined surface. A cavity is provided inside the fixed base 3, and the push block 10 is located inside the cavity. A slider 11 is slidably mounted inside the cavity, and the sliding push rod 6 is fixedly mounted through the slider 11. The side of the slider 11 near the push block 10 is a second inclined surface, and the second inclined surface abuts against the first inclined surface.

[0037] This utility model, by setting a sliding push rod 6 and a longitudinal cylinder 9, such as... Figure 4 As shown, before the fixed car chassis 1 is installed, the longitudinal cylinder 9 is in the shortened state. At this time, the push block 10 is at the highest point of its stroke, and under the elastic force of the return spring 7, it can push the sliding push rod 6 to... Figure 4 As shown, the left side slides, at which point the limit push plate 4 is located at the leftmost end of its stroke.

[0038] After the car floor 1 is installed and fixed, the longitudinal cylinder 9 can be activated. The telescopic end of the longitudinal cylinder 9 extends and pushes the push block 10 downward. With the cooperation of the second inclined surface and the first inclined surface, the downward-moving push block 10 pushes the right slider 11 to slide to the right. The slider 11 drives the sliding push rod 6 and the limiting push plate 4 to slide to the left together until the limiting push plate 4 slides tightly against the side wall of the car floor 1. Figure 2 As shown, since the telescopic end of the displacement sensor 5 abuts against the limiting push plate 4, the telescopic end of the displacement sensor 5 extends synchronously while the limiting push plate 4 slides to the right, thus enabling real-time detection of the displacement of the limiting push plate 4. After the detection is completed, the longitudinal cylinder 9 shortens, at which point the push block 10 moves upward, and under the elastic force of the return spring 7, pushes the sliding push rod 6 and the limiting push plate 4 together to slide to the left to reset.

[0039] like Figures 1-6 As shown, in some embodiments, the clamping device 66 includes a clamping plate 13, a swing arm 15, and a mounting bracket 12 disposed on the top of the base 2. The mounting bracket 12 is provided with a mounting plate 14. One end of the swing arm 15 is rotatably disposed on the mounting plate 14 via a first pin 16, and the clamping plate 13 is disposed on the swing arm 15.

[0040] It also includes a clamping cylinder 17 and a pulling plate 19. The clamping cylinder 17 is rotatably mounted on the mounting bracket 12 via a second pin 18. The telescopic end of the clamping cylinder 17 is rotatably connected to one end of the pulling plate 19 via a third pin 20, and the other end of the pulling plate 19 is rotatably connected to the swing arm 15 via a fourth pin 21. It also includes a connecting plate 22, the length of which is greater than the length of the pulling plate 19. One end of the connecting plate 22 is rotatably connected to the third pin 20, and the other end of the connecting plate 22 is rotatably connected to the mounting plate 14 via a fifth pin 23. The clamping plate 13 in this embodiment can take two shapes, such as... Figure 5 and Figure 6 The disc-shaped clamping plate 13 shown can be made of rubber material. Alternatively, it can be made of... Figure 7 The cubic-shaped clamping plate 13 shown can be made of metal and can be used to clamp the position of the car floor 1 with weld seams.

[0041] This invention, by setting up a clamping plate 13 and a clamping cylinder 17, allows the clamping cylinder 17 to be activated after the car floor 1 is installed on the top of the base 2. The clamping cylinder 17 extends and pushes the swing arm 15 downwards via the connecting plate 22 and the pulling plate 19. At this time, the swing arm 15 drives the clamping plate 13 downwards and tightly abuts against the top of the car floor 1, thus clamping and fixing the car floor 1. This operation is convenient. When it is necessary to remove the car floor 1, the clamping cylinder 17 can be shortened. Then, by pulling the swing arm 15 upwards to reset it, the car floor 1 can be removed.
