Description

Technical Field

[0001] The utility model relates to the field of automobile component production, in particular to a profilometer for automobile component production. Background Art

[0002] As a key inspection tool in the automotive parts production process, profilometers play a vital role. They are primarily used to measure key parameters such as outline dimensions and shape accuracy to ensure that component quality meets design requirements. However, traditional profilometers often face a challenge during measurement: ensuring that the support brackets supporting the components adhere closely to the varying shapes of the automotive parts, providing a stable measurement environment.

[0003] Traditional profilometer supports are typically made of rigid materials with fixed shapes and dimensions. While this design can meet basic measurement requirements to a certain extent, it struggles with the complex shapes and varied curves of automotive parts. Because the rigid support doesn't fully conform to the part surface, it can cause vibrations or gaps during measurement, compromising measurement accuracy and stability.

[0004] To this end, a support bracket is proposed that can be adaptively adjusted according to the shape of the automobile part during the detection process, so that the support bracket can fit the surface of the part while enhancing the stability during the measurement process. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies and provides a profilometer for automotive component production. By providing a stable platform, the platform features an elastically deformable layer composed of an elastic material or a memory alloy, with corrugated upper and lower end surfaces. When an automotive component is placed on the platform, the elastically deformable layer adaptively changes shape to fit the component's surface, minimizing gaps and vibrations during measurement. This significantly improves measurement stability and accuracy, ensuring precise measurement of the component's contour dimensions and shape.

[0006] In order to solve the above technical problems, the present invention solves the problem that the support bracket of the profilometer used in automobile parts production cannot be adaptively adjusted according to the shape of the automobile parts through the following technical solutions.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A profilometer for automobile parts production includes a contour detector arranged on an instrument base, a stabilizing platform is provided below the contour detector for stabilizing the parts, and positioning structures are provided around the stabilizing platform for positioning the parts. The stabilizing platform includes a rigid support layer, an elastic deformation layer and a top structure stacked in sequence, and a supporting structure is provided at the bottom of the stabilizing platform, which is used to adjust the height of the stabilizing platform.

[0009] Preferably, the rigid support layer, the elastic deformation layer and the top structure are sequentially arranged above the support structure from bottom to top, and the upper and lower end surfaces of the elastic deformation layer are both constructed in a corrugated state.

[0010] Preferably, the support structure includes a support tube and a first threaded rotating rod, and the first threaded rotating rod is threadably connected to the interior of the support tube.

[0011] Preferably, the top structure includes a wear-resistant contact layer and an outer fixing frame, the wear-resistant contact layer covers the surface of the elastic deformation layer, and the outer fixing frame is connected to the outer periphery of the wear-resistant contact layer and is spliced ​​with the rigid support layer.

[0012] Preferably, the first threaded rotating rod is connected to the stabilizing platform via a spherical connector.

[0013] Preferably, a rotating disk is connected to the bottom of the support structure, and a rotating assembly is arranged between the rotating disk and the instrument base. The rotating assembly includes a rotating seat, an annular rotating groove and a rotating member. The rotating member is connected to the bottom of the rotating disk. The annular rotating groove is opened inside the rotating seat and allows the rotating member to be rotatably connected therein.

[0014] Preferably, a locking assembly is provided between the rotating member and the annular rotating groove, and the locking assembly includes a second threaded rotating rod and an extrusion block. A threaded hole is opened on the rotating member and extends to the outside of the rotating disk and is connected to a nut ring. The second threaded rotating rod is threadedly connected to the nut ring and the inside of the threaded hole. The extrusion block is connected to the bottom of the second threaded rotating rod and can produce an extrusion state with the bottom of the inner wall of the annular rotating groove.

[0015] Preferably, the outer periphery of the top of the rotating seat is connected with a stabilizing ring, and the stabilizing ring surrounds the outer periphery of the rotating disk for stability.

[0016] Preferably, a stretchable steel wire structure is connected to the positioning structure to adjust the fixed position of the positioning structure. An assembly plate is provided at one end of the steel wire structure away from the positioning structure, and the assembly plate and the stabilizing platform are fastened by bolts.

[0017] Preferably, the rotating seat and the instrument base are connected through an adjustment component, and the adjustment component includes a slider, a sliding groove and a limit plate. The slider is connected to the bottom of the rotating seat and can slide inside the sliding groove. The sliding groove is opened inside the instrument base. The limit plate is connected to both ends of the sliding groove to limit the movement of the rotating seat.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The automotive parts production profilometer provided in this application utilizes a stable platform with an elastically deformable layer composed of an elastic material or a memory alloy, and having corrugated upper and lower end surfaces. When an automotive part is placed on the platform, the elastically deformable layer adaptively changes shape to fit the part's surface, reducing backlash and vibration during measurement. This significantly improves measurement stability and accuracy, ensuring precise measurement of the part's contour dimensions and shape accuracy.

[0020] This application utilizes a support structure that allows the height of the stabilizing platform to be adjusted by rotating the first threaded rod within the support cylinder. The horizontal angle can be adjusted by cooperating with the rotating disk and the rotating seat, and the angle can be precisely fixed using a locking assembly. This precise adjustment ensures that the area of ​​the automotive component to be inspected is accurately within the detection range of the contour detector, further guaranteeing the accuracy of the measurement results.

[0021] This application utilizes a height-adjustable stabilizing platform to accommodate automotive parts of varying sizes. Furthermore, the angle adjustment between the rotating disk and the rotating base, along with the elastic deformation layer of the stabilizing platform, allows for optimal adaptation to various automotive part shapes, including those with complex curves. Furthermore, the position of the rotating base can be adjusted within a certain range using an adjustment component, further enhancing the profilometer's adaptability to components of varying shapes and sizes, enabling its widespread application in inspecting a wide range of automotive parts.

[0022] The present application uses positioning structures arranged around a stable platform, combined with a stretchable steel wire structure and an assembly plate, to conveniently position and fix automotive components, thereby preventing the components from shifting during the measurement process. The operation is relatively simple, which reduces the preparation time before measurement and improves measurement efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Example

[0038] See also Figure 1 - Figure 9 A profilometer for automobile parts production includes a contour detector 101 arranged on an instrument base 1, a stabilizing platform 2 is provided below the contour detector 101 for stabilizing the parts, and positioning structures 7 are provided around the stabilizing platform 2 for positioning the parts. The stabilizing platform 2 includes a rigid support layer 201, an elastic deformation layer 202 and a top structure 203 stacked in sequence, and a supporting structure 3 is provided at the bottom of the stabilizing platform 2, which is used to adjust the height of the stabilizing platform 2.

[0039] The profiler for automobile parts production in this application is mainly composed of an instrument base 1, a profile detector 101, a stable platform 2, a rigid support layer 201, an elastic deformation layer 202, a top structure 203 and a positioning structure 7. The following is a detailed structure and working principle.

[0040] 1. Overall structure assembly

[0041] (1) Instrument Base 1 and Contour Detector 101 The instrument base 1 is the foundation of the entire profilometer. The contour detector 101 is arranged on the instrument base 1 and is used to perform contour detection on automobile parts.

[0042] (2) Stable platform

[0043] Basic components of the stable platform 2

[0044] The stable platform 2 is located below the contour detector 101 and includes a rigid support layer 201 , an elastic deformation layer 202 and a top structure 203 stacked in sequence.

[0045] The rigid support layer 201 is made of high-strength metal materials such as stainless steel or aluminum alloy, which provides sufficient support strength for the entire stable platform 2 to ensure that it can bear the weight of the automobile parts during the measurement process.

[0046] The elastically deformable layer 202, located above the rigid support layer 201, is composed of an elastic material such as highly elastic rubber, silicone, or memory alloy. This material deforms when subjected to force, allowing the stabilizing platform to adapt to the various shapes of automotive component surfaces. The upper and lower surfaces of the elastically deformable layer 202 are corrugated. This corrugated structure facilitates elastic deformation in various directions, increases contact area with adjacent layers, and enhances structural stability.

[0047] The top structure 203, located above the elastically deformable layer 202, comprises a wear-resistant contact layer 2031 and an external retaining frame 2032. The wear-resistant contact layer 2031 directly contacts the automotive components and is made of a material with high wear resistance and a low coefficient of friction, such as a polytetrafluoroethylene coating, to prevent scratches on the product surface during measurement. The external retaining frame 2032 is attached to the outer periphery of the wear-resistant contact layer 2031 and is spliced ​​to the rigid support layer 201, securing and protecting the wear-resistant contact layer 2031.

[0048] (3) Support structure 3 and height adjustment

[0049] Connection between support structure 3 and stabilizing platform 2

[0050] The supporting structure 3 includes a supporting tube 301 and a first threaded rotating rod 302 . The bottom of the supporting tube 301 is connected to the instrument base 1 , and the first threaded rotating rod 302 is threadably connected to the inside of the supporting tube 301 .

[0051] The bottom of the stabilizing platform 2 is connected to the first threaded rod 302 via a spherical connector 3011. This connection allows the stabilizing platform 2 to achieve nearly full rotation on the support structure 3 during use, adapting to the support requirements of products of varying shapes. By rotating the first threaded rod 302, the stabilizing platform 2 can be moved up and down within the support tube 301, thereby adjusting the height of the stabilizing platform 2. This height adjustment mechanism accommodates automotive parts of varying sizes, ensuring that they are accurately within the detection range of the contour detector 101.

[0052] (IV) Rotating disk 4 and rotating seat 5

[0053] Connection between rotating disk 4 and rotating seat 5

[0054] A rotating disk 4 is fixedly connected to the bottom of the support structure 3. A rotating base 5 is mounted on the instrument base 1. A rotating member 401 at the bottom of the rotating disk 4 is rotatably connected to an annular rotating groove 501 of the rotating base 5. Rotating the rotating disk 4 drives the rotating member 401 to rotate relative to the interior of the annular rotating groove 501, thereby changing the angle of the support structure 3 and the stabilizing platform 2 on the support structure 3. The operator can precisely adjust the angle according to the scale based on the product shape and fix the angle using a locking mechanism. A stabilizing ring 502 is connected to the outer periphery of the top of the rotating base 5. The stabilizing ring 502 surrounds the outer periphery of the rotating disk 4 and stabilizes the rotating disk 4, preventing it from shifting during rotation.

[0055] Locking assembly of rotating disk 4

[0056] A locking assembly is provided between the rotating member 401 and the annular rotating groove 501, and the locking assembly includes a second threaded rotating rod 402 and an extrusion block 403. The extrusion block 403 is elastic and is glued to the bottom of the second threaded rotating rod 402. A threaded hole is provided on the rotating member 401 and extends to the outside of the rotating disk 4 and is connected to a nut ring. The second threaded rotating rod 402 is threadedly connected to the nut ring and the inside of the threaded hole, and the extrusion block 403 is connected to the bottom of the second threaded rotating rod 402. When the position of the rotating disk 4 needs to be fixed, the second threaded rotating rod 402 is rotated so that the extrusion block 403 and the bottom of the inner wall of the annular rotating groove 501 are in an extrusion state, thereby fixing the rotating disk 4 at the desired angular position. This rotating and locking assembly allows the stabilizing platform 2 to be adjusted in the horizontal direction to better adapt to the shape of the automobile part and ensure that the stabilizing platform 2 fits tightly against the surface of the automobile part.

[0057] (V) Positioning structure 7

[0058] Composition and adjustment of steel wire structure 701

[0059] Positioning structures 7 are installed around the stabilizing platform 2. Attached to these structures are stretchable wire structures 701. Mounting plates 702 are located on the ends of the wire structures 701 facing away from the positioning structures 7. Bolts secure the mounting plates 702 to the stabilizing platform 2. By stretching or contracting the wire structures 701, the fixed position of the positioning structures 7 can be adjusted, thereby accurately positioning the vehicle component and ensuring it remains stable and prevents displacement during measurement.

[0060] Six adjustment components

[0061] Connection and adjustment of rotating seat 5 and instrument base 1

[0062] The rotating base 5 is connected to the instrument base 1 via an adjustment assembly comprising a slider 6, a sliding slot 601, and a stopper plate 602. The slider 6 is attached to the bottom of the rotating base 5. The sliding slot 601 is defined within the instrument base 1, allowing the slider 6 to slide within the slot 601. Stopper plates 602 are connected to both ends of the slot 601 to limit the range of movement of the rotating base 5 connected to the slider 6. This sliding connection and stopper mechanism allows the position of the rotating base 5 and its associated stabilizing platform 2 relative to the instrument base 1 to be adjusted within a certain range, further enhancing adaptability to automotive components of varying shapes and sizes.

[0063] 2. Working Principle

[0064] 1. Adaptive Adjustment of Stable Platform 2

[0065] Height adjustment

[0066] When measuring automobile parts of different heights, the first threaded rod 302 is rotated to move it up and down in the support cylinder 301, thereby raising or lowering the stabilizing platform 2. This ensures that the part to be inspected is within the detection range of the contour detector 101.

[0067] Angle adjustment

[0068] Horizontally, when the stabilizing platform 2 needs to conform to the specific shape of an automotive part, the rotating disk 4 can rotate around the annular rotating groove 501 of the rotating base 5. After adjusting to the appropriate angle, the second threaded rotating rod 402 is rotated to cause the extrusion block 403 to press against the bottom of the inner wall of the annular rotating groove 501, thereby fixing the rotating disk 4 at the desired angle. This angle adjustment allows the stabilizing platform 2 to better conform to the curved surface of the automotive part.

[0069] Function of the elastic deformation layer 202

[0070] Within the stabilizing platform 2, the elastically deformable layer 202 plays a key role in self-adaptation. When an automotive component is placed on the stabilizing platform 2, its shape causes the elastically deformable layer 202 to deform. Due to its material properties and corrugated structure, the elastically deformable layer 202 is able to elastically deform in various directions, allowing the entire stabilizing platform 2 to conform closely to the surface of the automotive component, reducing play and vibration during measurement and improving measurement stability and accuracy.

[0071] (2) Component positioning and fixation

[0072] Function of positioning structure 7

[0073] The positioning structure 7, along with its wire structure 701 and mounting plate 702, is used to position automotive components. Because the wire structure 701 is designed to be folded, it can be stretched relative to the components. By stretching or contracting the wire structure 701, the positioning structure 7 can be adjusted, allowing the mounting plate 702 to mate with the stabilizing platform 2, securing the automotive component to the platform. This prevents displacement of the automotive component during measurement, ensuring accurate measurements.

[0074] (3) Overall collaborative work

[0075] Coordination of various components

[0076] During the measurement process, through the coordinated operation of various mechanisms such as height adjustment, angle adjustment, adaptation of the elastic deformation layer 202, and fixation of the positioning structure 7, the stable platform 2 can closely fit the surfaces of automobile parts of different shapes and sizes, providing a stable measurement environment for the contour detector 101, thereby accurately measuring key parameters such as the contour size and shape accuracy of automobile parts, and ensuring that the quality of the parts meets the design requirements.

[0077] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are intended only as examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and illustrated in the embodiments.
