Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle manufacturing, and more specifically to positioning and detection tooling. Background Technology
[0002] With the upgrading of vehicle emission regulations and the implementation of the China VI standard, the quality control of commercial vehicle exhaust aftertreatment systems has become more optimized, placing higher demands on testing equipment. Currently, aftertreatment testing involves placing the aftertreatment product directly on a testing platform, relying on its own weight for stability. However, directly placing the aftertreatment product on the testing platform and relying solely on its own weight for stability carries the risk of product impact and subsequent appearance defects. Furthermore, the lack of dedicated positioning points and the absence of product locking mechanisms during testing pose a risk of rolling and falling, leading to test failures and product damage. Additionally, the testing process may involve shaking or displacement, increasing testing errors. Utility Model Content
[0003] The purpose of this invention is to overcome the problems in the existing technology where placing post-processed products directly on a platform for testing causes shaking, vibration, inaccurate measurement, and displacement changes due to human touch, which affect the test results. This invention provides a positioning test fixture that has a positioning function, allowing the post-processed products to be placed stably on the positioning test fixture.
[0004] To achieve the above objectives, this utility model provides a positioning and detection fixture for detecting automotive after-processing products. It includes a base plate and limiting components fixedly connected to the base plate. Multiple sets of limiting components are provided, distributed around the circumference of the after-processing product to restrict its movement. At least four sets of limiting components are provided around the circumference of the after-processing product.
[0005] Multiple sets of limiting components are circumferentially distributed on the post-processing product to limit the movement of the post-processing product during the inspection process. At least four sets are set on the circumferential direction of the post-processing product to stably limit the post-processing product in the circumferential direction.
[0006] Preferably, the limiting components include a first limiting module, a second contouring module, a third contouring module, a fourth limiting module, a fifth contouring module, a sixth limiting module, a seventh limiting module, and an eighth contouring module, with the eight sets of limiting components distributed around the periphery of the post-processed product.
[0007] Setting eight sets of limit components is one embodiment of limit component configuration. The distribution of the eight sets of limit components needs to match the shape and structure of the post-processing product to better position it. Setting eight sets of limit components can stably confine the post-processing product within a certain range, which is beneficial for smooth inspection.
[0008] Preferably, the outer peripheral surface of the post-processing product has an arc-shaped structure, and the limiting component also includes an arc-shaped contouring module to match the arc-shaped structure of the post-processing product.
[0009] In embodiments where the outer periphery of the post-processing product has an arc-shaped structure, the limiting component is provided with an arc-shaped contouring module. The arc-shaped contouring module can better fit the arc-shaped structure of the post-processing product, further enhancing the positioning of the post-processing product and further facilitating the smooth progress of testing.
[0010] Preferably, the bottom of the post-processed product is placed on the positioning and detection fixture, the distribution of the limiting components corresponds to the bottom of the post-processed product, and at least one set of arc-shaped contouring modules is distributed in the same direction on the bottom of the post-processed product.
[0011] In an embodiment where the bottom of the post-processing product is placed in the positioning and detection fixture, at least one set of arc-shaped contouring modules is provided in the front, back, left, and right directions of the post-processing product, which helps to confine the post-processing product within the positioning and detection fixture.
[0012] Preferably, the second contouring module, the third contouring module, the fifth contouring module, the sixth limiting module, the seventh limiting module, and the eighth contouring module are all provided with arc-shaped contouring modules.
[0013] A set of arc-shaped contouring modules is set on the front side of the post-processing product, a set of arc-shaped contouring modules is set on the rear side, two sets of arc-shaped contouring modules are set on the left side, and two sets of arc-shaped contouring modules are set on the right side. This setting further improves the stability of the post-processing product when it is confined to the positioning and detection fixture.
[0014] Preferably, the base plate is also fixedly installed with support components, and at least three sets of support components are provided to support the post-processed products.
[0015] Support components can provide support for the product behind it. Three sets of support components can form a stable support surface. Setting at least three sets of support components can achieve more stable support.
[0016] Preferably, the support components include a first support module, a fourth support module, a sixth support module, a seventh support module, and a ninth contouring module.
[0017] Five sets of support components can provide more stable support for post-processing products.
[0018] Preferably, the first limiting module and the first support module are connected to form the first contouring module, the fourth limiting module and the fourth support module are connected to form the fourth contouring module, the sixth limiting module and the sixth support module are connected to form the sixth contouring module, and the seventh limiting module and the seventh support module are connected to form the seventh contouring module.
[0019] When the limiting component and the support component can be combined and connected together, the overall structure of the positioning and detection fixture becomes simpler and the installation becomes more convenient.
[0020] Preferably, the height of the support component is matched with the bottom structure of the limiting component and the post-processing product.
[0021] This setup allows the post-processed product to be placed stably on the positioning and testing fixture and confined within it.
[0022] Preferably, the limiting component, the support component, and the base plate are connected by bolts.
[0023] The bolt connection method is simple and easy to operate, making the installation of the positioning and testing fixture convenient and the operation simple.
[0024] Through the above technical solution, the positioning and detection fixture of this utility model can stably limit the post-processing product within a certain range through the limiting component, and can stably support the positioning and detection fixture through the supporting component. The installation method of combining the limiting component and the supporting component can simplify the assembly operation and can also position and limit the post-processing product well. Furthermore, the positioning and detection fixture of this utility model can be applied to post-processing products with the same bottom structure, and has a certain degree of versatility.

[0031] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0032] In this utility model, unless otherwise stated, directional terms such as "up, down, left, right, inside, outside, far, near, front" are generally used to refer to the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and therefore should not be construed as limiting this utility model.
[0033] like Figures 1-4 The diagram shows a positioning and detection fixture for detecting automotive after-processing products 2. It includes a base plate 1 and limiting components fixedly connected to the base plate 1. Multiple sets of limiting components are provided, distributed in the circumferential direction of the after-processing product 2 to restrict the movement of the after-processing product 2. At least four sets of limiting components are provided in the circumferential direction of the after-processing product 2.
[0034] Specifically, base plate 1 is placed on the testing platform, and multiple sets of limiting components are fixedly connected to base plate 1. These limiting components are distributed around the circumference of the automotive aftertreatment product 2, thereby limiting the movement of the aftertreatment product 2 during testing, such as swaying, tilting, and changes in horizontal displacement. To ensure stable positioning of the aftertreatment product, at least four sets of limiting components need to be installed around its circumference. It should be noted that the distribution of these limiting components must be compatible with the external structure of the aftertreatment product 2 to stably contain it and reduce testing errors caused by movement during various tests.
[0035] Furthermore, the limiting components include a first limiting module 111, a second contouring module 12, a third contouring module 13, a fourth limiting module 141, a fifth contouring module 15, a sixth limiting module 161, a seventh limiting module 171, and an eighth contouring module 18, with the eight sets of limiting components distributed around the circumference of the post-processing product 2.
[0036] Specifically, the limiting components are circumferentially distributed around the post-processing product 2, and their ability to restrict the lateral movement of the post-processing product 2 is sufficient. There are various distribution methods for the limiting components; setting eight groups of limiting components is one embodiment. In such cases... Figure 2 In the illustrated embodiment, the limiting components are configured into eight groups, specifically a first limiting module 111, a second contouring module 12, a third contouring module 13, a fourth limiting module 141, a fifth contouring module 15, a sixth limiting module 161, a seventh limiting module 171, and an eighth contouring module 18. It should be noted that the distribution of the eight groups of limiting components needs to match the external shape of the post-processing product 2 to better define its positioning.
[0037] Furthermore, the outer peripheral surface of the post-processing product 2 has an arc-shaped structure, and the limiting component also includes an arc-shaped contouring module to match the arc-shaped structure of the post-processing product 2.
[0038] like Figure 4 In the illustrated embodiment, the outer peripheral surface of the post-processing product 2 has an arc-shaped structure, and correspondingly, the structure of the limiting component matches the arc-shaped structure of the post-processing product 2. Specifically, the limiting component is provided with an arc-shaped contouring module, the arc surface of which corresponds to the arc surface of the outer peripheral surface of the post-processing product 2, so that the arc-shaped contouring module and the arc-shaped structure of the post-processing product 2 can fit together better, such as... Figure 2 As shown.
[0039] Furthermore, the bottom of the post-processing product 2 is placed on a positioning and detection fixture, and the distribution of the limiting components corresponds to the bottom of the post-processing product 2. At least one set of arc-shaped contouring modules is distributed in the same direction on the bottom of the post-processing product 2.
[0040] like Figure 4 In the illustrated embodiment, the bottom of the post-processing product 2 is attached to the limiting components. The bottom of the post-processing product 2 is a cuboid structure with rounded corners. Corresponding to this structure, the distribution of the eight sets of limiting components matches the cuboid structure with rounded corners, with two sets of limiting components distributed in each direction, such as... Figure 2 In the illustrated embodiment, the first limiting module 111 and the eighth contouring module 18 are disposed on the front side of the post-processing product 2, the fourth limiting module 141 and the fifth contouring module 15 are disposed on the rear side of the post-processing product 2, the second contouring module 12 and the third contouring module 13 are disposed on the left side of the post-processing product 2, and the sixth limiting module 161 and the seventh limiting module 171 are disposed on the right side of the post-processing product 2, so that the post-processing product 2 can be stably constrained within the positioning and detection fixture. It should be noted that the bottom of the post-processing product 2 has four directions, and at least one set of arc-shaped contouring modules is provided in each direction to further facilitate the confinement of the post-processing product 2 within the positioning and detection fixture.
[0041] Furthermore, the second contouring module 12, the third contouring module 13, the fifth contouring module 15, the sixth limiting module 161, the seventh limiting module 171 and the eighth contouring module 18 are all equipped with arc-shaped contouring modules.
[0042] Specifically, the second contouring module 12, the third contouring module 13, the fifth contouring module 15, the sixth limiting module 161, the seventh limiting module 171, and the eighth contouring module 18 are equipped with arc-shaped contouring modules, which can better fit the bottom of the post-processing product 2. This results in the post-processing product 2 having one set of arc-shaped contouring modules on the front side, one set of arc-shaped contouring modules on the rear side, two sets of arc-shaped contouring modules on the left side, and two sets of arc-shaped contouring modules on the right side, thereby further improving the stability of the post-processing product 2 within the positioning and detection fixture.
[0043] Furthermore, the base plate 1 is also fixedly equipped with support components, and at least three sets of support components are provided to support the post-processed product 2.
[0044] To further stabilize the post-processing product 2 on the positioning and detection fixture, support components are also installed on the base plate 1 of the positioning and detection fixture to stably support the post-processing product 2. It should be noted that at least three sets of support components are used to support the post-processing product 2. The three sets of support components can form a stable support surface, which can achieve more stable support.
[0045] Furthermore, the support components include a first support module 112, a fourth support module 142, a sixth support module 162, a seventh support module 172, and a ninth contouring module 19.
[0046] Specifically, such as Figure 2 As shown, the first support module 112, the fourth support module 142, the sixth support module 162, the seventh support module 172 and the ninth contouring module 19 are all support components. The five sets of support components can stably support the post-processing product 2.
[0047] Furthermore, the first limiting module 111 and the first support module 112 are connected to form the first contouring module 11, the fourth limiting module 141 and the fourth support module 142 are connected to form the fourth contouring module 14, the sixth limiting module 161 and the sixth support module 162 are connected to form the sixth contouring module 16, and the seventh limiting module 171 and the seventh support module 172 are connected to form the seventh contouring module 17.
[0048] like Figure 2 In the embodiment shown, to simplify the installation process and facilitate equipment maintenance, some limiting components and some supporting components can be connected together. Specifically, the first limiting module 111 and the first supporting module 112 are connected to form the first contouring module 11, the fourth limiting module 141 and the fourth supporting module 142 are connected to form the fourth contouring module 14, the sixth limiting module 161 and the sixth supporting module 162 are connected to form the sixth contouring module 16, and the seventh limiting module 171 and the seventh supporting module 172 are connected to form the seventh contouring module 17, thereby making the overall structure of the positioning and detection fixture simpler.
[0049] Furthermore, the height of the support components is coordinated with the bottom structure of the limiting components and the post-processing product 2.
[0050] To better fit the bottom of post-processing product 2, the height of the support component needs to match the limiting component and the bottom structure of post-processing product 2. For example... Figure 2 In the illustrated embodiment, the heights of the first support module 112, the ninth contouring module 19, and the fourth support module 142 are matched with the bottom structure of the post-processing product 2. For example, if the ground of the post-processing product 2 has a protruding structure, the corresponding support component needs to be height adjusted according to the protruding structure to match it. Simultaneously, the height of the arc-shaped structure of the limiting component with the arc-shaped contouring module also needs to match the structure of the support component and the bottom of the post-processing product 2, so that the post-processing product 2 can be placed stably on the support component, and the arc-shaped contouring module of the limiting component fits snugly with the arc-shaped structure at the bottom of the post-processing product 2, ensuring that the post-processing product 2 is stably positioned on the positioning and detection fixture.
[0051] Furthermore, the limiting component, the support component, and the base plate 1 are connected by bolts.
[0052] The connection between the limiting component, the support component, and the base plate 1 is a bolted connection, making the assembly of the positioning and detection fixture simple and efficient. It should be noted that, as... Figure 2 In the embodiments shown, in structures that have both arc-shaped contouring modules and support components, such as the fourth contouring module 14, the sixth contouring module 16, and the seventh contouring module 17, the arc-shaped contouring module can be installed on the support component.
[0053] Therefore, the positioning and testing fixture is used for supporting and positioning the post-processing product 2, and any post-processing product 2 with the same bottom structure can be placed on this positioning and testing fixture for various tests. The positioning and testing fixture of this utility model is a general-purpose fixture with a simple structure and convenient installation.
[0054] It should be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
[0055] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
