Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing device technology, and in particular to a three-dimensional testing and fixing device for a variable diameter adaptable clutch pressure plate. Background Technology
[0002] The clutch pressure plate is an important structure on the clutch, and its function plays a vital role in vehicle driving safety.
[0003] Currently, there are many models of clutch pressure plates, which cannot meet the clamping requirements of different models of clutches.
[0004] The existing technology, CN204534037U, describes a multi-angle, multi-directional shooting camera. Currently, similar Y-shaped structures are used in conjunction with mounting fixtures. However, the excessively large adjustment range of the clutch pressure plate leads to structural complexity and difficulty in ensuring adjustment accuracy. For example, using a multi-stage telescopic structure to accommodate different outer diameters results in increased cumulative errors during adjustment due to the large number of components, making it difficult to accurately position pressure plates of different outer diameters and affecting detection accuracy. Conversely, reducing the adjustment range to ensure accuracy makes it impossible to accommodate multiple pressure plates.
[0005] Ensuring stability for pressure plate upright testing under varying outer diameters is not easy. If the support structure of a general-purpose device is designed for common pressure plate sizes, instability may occur for pressure plates with significantly different outer diameters. For example, with a large-diameter pressure plate, an unreasonable distribution of support points may cause the pressure plate to tip over during flipping testing; while for a small-diameter pressure plate, the support structure may be too bulky, affecting operational convenience and making it difficult to meet the upright stability requirements of pressure plates with different outer diameters through simple adjustments.
[0006] For different clutch models, each specialized device requires redesigning and manufacturing new molds for its components. For the diverse range of clutch pressure plates, this repetitive investment in costs is enormous. Designing a universal device to achieve high-precision diameter adaptation, stable vertical mounting, and pressure-free mounting requires significant R&D investment in material selection and structural design. Furthermore, balancing cost and performance is difficult, easily leading to cost overruns while still failing to fully meet functional requirements.
[0007] Therefore, it is necessary to design a three-dimensional detection and fixing device for the pressure plate of a variable-diameter adaptive clutch to solve the above problems. Utility Model Content
[0008] The purpose of this invention is to provide a three-dimensional detection and fixing device for a variable diameter adaptable clutch pressure plate, so as to overcome the above-mentioned shortcomings of the existing technology.
[0009] To achieve the above objectives, the present invention adopts the following technical solution:
[0010] A three-dimensional detection and fixing device for a variable diameter adaptable clutch pressure plate includes a bottom fixed base and a positioning mounting frame installed on the bottom fixed base. The positioning mounting frame has a Y-shaped structure and is connected to the bottom fixed base by mechanical connection or welding. The positioning mounting frame has several sets of guide slides. A magnet seat, a positioning pin, and a fixing bolt fixedly connected to the magnet seat or positioning pin for locking onto the guide slide are slidably arranged in the guide slides.
[0011] Preferably, reinforcing ribs are installed on one end face on both sides of the positioning mounting bracket.
[0012] Preferably, a reinforcing connecting block is also provided between the top ends of the positioning mounting bracket.
[0013] Preferably, the guide rail is further provided with magnetic positioning points for magnetic connection with the magnet base.
[0014] The beneficial effects of this utility model are as follows: This technical solution, through adjustable positioning pins and a magnetic positioning structure, can flexibly change the position of the positioning point, thereby adapting to clutch pressure plates of different outer diameters. Whether the pressure plate is small or large, precise positioning and fixing can be achieved, solving the problem of inspection and fixing caused by the wide variety of clutch pressure plates and large differences in outer diameter. This greatly improves the versatility of the inspection and fixing device and reduces the cost and time consumption of designing special fixtures for different pressure plates.

[0019] Reference Figures 1 to 3 A three-dimensional detection and fixing device for a variable diameter adaptable clutch pressure plate, comprising a bottom fixing seat 1 and a positioning mounting bracket 2 mounted on the bottom fixing seat;
[0020] To ensure the strength of the positioning mounting bracket and prevent loosening, reinforcing ribs 3, made of 45# steel, are installed on one end face of both sides of the Y-shaped mounting bracket. These ribs are installed on key load-bearing parts such as the base plate or positioning bracket to enhance the strength and rigidity of the structure, prevent deformation due to stress during testing, ensure the stability of the entire fixing device, and thus guarantee testing accuracy. The shape and layout of the reinforcing ribs are designed according to mechanical principles to maximize the load-bearing capacity of the structure.
[0021] The bottom fixing base 1 and the positioning mounting bracket 2 can be fixed together by welding, bolting, or other mechanical connection methods to ensure that the positioning bracket is stable on the base plate and can withstand the weight of the pressure plate and external forces during the testing process.
[0022] The bottom fixing base 1, serving as the basic support structure of the entire fixing device, is made of high-strength and stable materials, such as steel, to ensure the overall stability of the device during testing and prevent shaking or displacement from affecting testing accuracy. Its shape and size are designed according to the actual application scenario and the worktable size of the testing equipment, generally having a large planar area and a certain thickness to provide sufficient support.
[0023] The positioning mounting bracket 2 has an overall Y-shaped structure. In order to prevent the forces on both sides from being too small and to enhance its stability, a reinforcing connecting block 4 is also provided between the top ends of the positioning mounting bracket 2 to improve the overall strength. The material is also 45# steel.
[0024] The positioning mounting bracket 2 is provided with several sets of guide slide rails 21. A magnet seat 22, a positioning pin 23, and a fixing bolt 24 are slidably arranged in the guide slide rails and are fixedly connected to the magnet seat or positioning pin for locking onto the guide slide rail. Magnetic positioning points are also provided on the guide slide rails 21 to cooperate with the magnet seat 22 for magnetic connection and to achieve a fixing effect.
[0025] With adjustable sets of locating pins and a magnetic locating structure, the position of the locating point can be flexibly changed to adapt to clutch pressure plates of different outer diameters. Whether the pressure plate is small or large, precise positioning and fixing can be achieved, solving the problem of inspection and fixing caused by the wide variety of clutch pressure plates and large differences in outer diameter. This greatly improves the versatility of the inspection and fixing device and reduces the cost and time spent designing special fixtures for different pressure plates.
[0026] The magnetic positioning method ensures that no pressure is applied to the pressure plate during fixing, preventing deformation caused by pressure and thus maintaining testing accuracy, meeting the "cannot be pressed" testing condition. Simultaneously, the pressure plate stands upright and is stably fixed, allowing the three-dimensional measuring instrument to inspect both sides of the pressure plate, obtaining comprehensive and accurate test data, providing a reliable basis for quality assessment of the clutch pressure plate; the locating pin assists in determining the initial position of the pressure plate, reducing adjustment errors.
[0027] To meet the positioning requirements of pressure plates with different outer diameters, it has a certain height so that the pressure plate can be placed stably when upright, and it is equipped with mounting positions for installing magnetic positioning points. The layout and dimensional accuracy of the mounting positions will affect the adjustment accuracy and stability of the magnetic positioning points.
[0028] The positioning pin is installed in the pre-processed guide rail on the positioning mounting bracket 2, using an interference fit or other fixing method to ensure that the positioning pin is accurately and stably positioned and will not shift during use.
[0029] In this embodiment, guide rails 21 are provided on both sides and in the middle of the positioning mounting bracket 2, and the corresponding positioning pins 23 and magnet seats 22 are installed in conjunction with the guide rails 21.
[0030] Based on the outer diameter of the clutch pressure plate to be tested, the three magnetic positioning points are initially adjusted by adjusting the position of the magnet seat on the positioning bracket. The operator moves the magnet seat or positioning pin along a specific direction of the guide rail to roughly determine the matching position between the magnetic positioning points and the outer diameter of the pressure plate;
[0031] Place the pressure plate 4 on the fixing device, ensuring that the outer diameter of the pressure plate mates with the locating pin, thus initially determining the position of the pressure plate. At this point, the pressure plate is in an upright position, ready for subsequent three-dimensional measurement. The fixing device can be a fixing cylinder that works with this device, or other structures that simply require a mechanism to fix the pressure plate onto the surface of the positioning mounting bracket 2.
[0032] Next, the position of the magnet holder is precisely adjusted. Observe whether the pressure plate is in a horizontal and stable state under the attraction of the magnetic positioning points. If the pressure plate is tilted or unstable, continue to adjust the shims until the pressure plate is stable and fixed. In this process, the three magnetic positioning points use magnetic force to attract the pressure plate, achieving pressure-free fixation, which meets the testing requirement that pressure cannot be applied to the pressure plate;
[0033] Once the pressure plate is stably fixed, the fixing device is placed on the worktable of the three-dimensional measuring machine for frontal inspection. After inspection, there is no need to readjust the magnetic positioning points and the position of the pressure plate; simply flip the pressure plate over and inspect again, achieving three-dimensional front and back inspection. Throughout the entire inspection process, reinforcing ribs ensure the structural strength and stability of the fixing device, preventing deformation due to stress and ensuring the accuracy of the inspection data.
[0034] The structure of this utility model mainly consists of a base plate, positioning bracket, reinforcing ribs, and other structural components made of materials such as 45# steel and CR12, which have high strength and good rigidity. The design of the reinforcing ribs further enhances the stability of the overall structure, enabling it to withstand the weight of the pressure plate and the external forces generated by the operation of the testing equipment during the testing process, preventing deformation and shaking, and ensuring the smooth progress of the testing work and the stability of the test data.
[0035] The advantages of this invention are that, through adjustable positioning pins and a magnetic positioning structure, the position of the positioning point can be flexibly changed, thus adapting to clutch pressure plates of different outer diameters. Whether the pressure plate is small or large, precise positioning and fixing can be achieved, solving the problem of inspection and fixing caused by the wide variety of clutch pressure plates and large differences in outer diameter. This greatly improves the versatility of the inspection and fixing device and reduces the cost and time spent designing special fixtures for different pressure plates.
[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
