Description

Technical Field

[0001] This utility model relates to the field of quality inspection device technology, and in particular to a quality inspection device for automotive pipeline welds. Background Technology

[0002] The automotive pipeline weld quality inspection device is a key piece of equipment used in the automotive manufacturing process to inspect the quality of pipeline welds. It mainly uses a variety of technical means to comprehensively evaluate the internal defects, mechanical properties, and sealing performance of the welds, ensuring the safety and reliability of the pipeline system. It detects defects such as porosity, slag inclusions, cracks, incomplete penetration, and incomplete fusion inside the welds, preventing pipeline leaks or breaks caused by defects. It also analyzes the geometric parameters of the welds (such as penetration depth, weld width, and weld leg height) to ensure that the mechanical properties (tensile strength, fatigue strength, etc.) meet the design standards.

[0003] The existing online inspection device for pipeline welds (publication number: CN104280399A) has at least the following drawbacks: after the pipeline is clamped, the weld is inspected online by a camera, but the location of the weld cannot be fixed. Therefore, the fixed camera position cannot inspect welds at different heights. At the same time, the camera can only inspect the welds on the outer wall of the pipeline and cannot inspect the welds on the inner wall of the pipeline online. Moreover, the interior of automotive pipelines is hollow and mostly cylindrical, and the device cannot rotate the pipeline to conduct a comprehensive and thorough inspection of the annular welds on its surface. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quality inspection device for automotive pipeline welds.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A quality inspection device for automotive pipeline welds includes a base, a chute frame, and a carriage. A drive motor is fixedly connected inside the base and located at the bottom of the chute frame. The bottom of the chute frame is integrally connected to the top of the base. The chute frame includes a lead screw, the top end of which is rotatably connected to the inner top of the chute frame, and the bottom end of which is rotatably connected to the inner bottom of the chute frame and the top of the base, and fixedly connected to the output end of the drive motor. The tail end of the carriage is located inside the chute frame and is threadedly connected to the lead screw. An industrial camera is fixedly connected inside one side of the carriage, and a rotating frame is provided on the top of the base.

[0006] As a further embodiment of this utility model, the rotating frame includes a rotating bolt and several positioning bolts. A crossbar on one side of the rotating frame is located at the top of the slide frame. The crossbar of the rotating frame is fixedly connected to the column of the rotating bolt, and the column of the rotating bolt is threadedly rotatably connected to the top of the slide frame.

[0007] As a further embodiment of this utility model, a driving cylinder is provided on one side of the slide frame. The driving cylinder is connected through to the square groove on one side of the rotating frame. A plurality of positioning bolts are threaded through to both sides of the outside of the rotating frame. One end of the rod of the positioning bolt abuts against the outer wall of the driving cylinder.

[0008] As a further embodiment of this utility model, the bottom of the driving cylinder is provided with a pipeline body, the telescopic end of the driving cylinder is slidably connected inside the pipeline body, a dual-crystal probe is provided inside the pipeline body, and the dual-crystal probe is fixedly connected to the bottom end of the telescopic end of the driving cylinder.

[0009] As a further embodiment of this utility model, the main body of the pipeline is located on the top of the base, a drive motor is fixedly connected inside the base, a rotating seat is provided on the top of the base, the bottom shaft of the rotating seat passes through the base and is fixedly connected to the output end of the drive motor, and the rotating seat includes an active clamping frame, a driven clamping frame and a rubber ring.

[0010] As a further embodiment of this utility model, the inner rings of both the active clamping frame and the driven clamping frame are fixedly connected with rubber rings. The bottom end of the pipeline body is located between the active clamping frame and the driven clamping frame. The rubber rings are attached to the outer wall of the bottom end of the pipeline body. The driven clamping frame is fixedly connected to one side of the opening of the active clamping frame by several bolts.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. After the drive motor starts, the output end drives the lead screw to rotate. Since the tail end of the slide is threadedly connected to the lead screw, the rotation of the lead screw is converted into the up-and-down linear motion of the slide within the slide rail. The industrial camera fixed on the slide moves with the slide, thereby adjusting the shooting height. It can shoot and inspect automotive pipeline welds at different heights. Through the transmission design of the drive motor and the lead screw, the height of the industrial camera is automatically adjusted. Compared with manual adjustment, this improves inspection efficiency and reduces labor intensity. At the same time, the precise transmission structure ensures that the industrial camera moves stably and accurately to the required inspection position, ensuring the accuracy of the shooting angle and position, thereby improving the quality of weld inspection images and the reliability of inspection results.

[0012] 2. Activate the drive cylinder. The extension and retraction end of the drive cylinder moves the dual-crystal probe up and down inside the pipeline body. The dual-crystal probe emits ultrasonic waves and receives the sound waves reflected back from the pipeline weld. Based on the characteristics of the reflected waves, it determines whether there are defects inside the weld, such as cracks or pores. Through the precise control of the drive cylinder, comprehensive inspection of welds at different locations in the pipeline can be performed, realizing ultrasonic non-destructive testing of automotive pipeline welds. It can detect internal defects that are difficult to detect with the naked eye, ensuring the quality and safety of automotive pipelines.

[0013] 3. After the drive motor starts, the output end drives the shaft at the bottom of the rotary table to rotate, thereby rotating the rotary table. The active and driven clamping frames on the rotary table clamp and fix the bottom end of the pipeline body. When the rotary table rotates, it drives the pipeline body to rotate together, so that the industrial camera and dual-crystal probe can perform all-round, no-dead-angle inspection of the weld seam during the rotation of the pipeline body. The rotation function of the rotary table, together with the industrial camera and dual-crystal probe, realizes 360-degree comprehensive inspection of the automotive pipeline weld seam, avoiding the problem of missed inspection due to insufficient inspection angle.

[0019] Reference Figures 1-4 A quality inspection device for automotive pipeline welds includes a base 1, a slide frame 2, and a slide 3. A drive motor 101 is fixedly connected inside the base 1. The drive motor 101 is located at the bottom of the slide frame 2. The bottom of the slide frame 2 is integrally connected to the top of the base 1. The slide frame 2 includes a lead screw 201. The top end of the lead screw 201 is rotatably connected to the inner top of the slide frame 2, and the bottom end of the lead screw 201 is rotatably connected to the inner bottom of the slide frame 2 and the top of the base 1, and is fixedly connected to the output end of the drive motor 101. The tail end of the slide 3 is located inside the slide frame 2, and the tail end of the slide 3 is threadedly connected to the lead screw 201. An industrial camera 301 is fixedly connected inside one side of the slide 3. A rotating frame 4 is provided on the top of the base 1.

[0020] In use, after the drive motor 101 starts, its output end drives the lead screw 201 to rotate. Since the tail end of the slide 3 is threadedly connected to the lead screw 201, the rotation of the lead screw 201 is converted into the up-and-down linear motion of the slide 3 within the slide frame 2. The industrial camera 301 fixed on the slide 3 moves with the slide 3, thereby adjusting the shooting height. It can shoot and inspect automotive pipeline welds at different heights. Through the transmission design of the drive motor 101 and the lead screw 201, the height of the industrial camera 301 is automatically adjusted. Compared with manual adjustment, this improves inspection efficiency and reduces labor intensity. At the same time, the precise transmission structure ensures that the industrial camera 301 moves stably and accurately to the required inspection position, ensuring the accuracy of the shooting angle and position, thereby improving the quality of the weld inspection image and the reliability of the inspection results.

[0021] In this embodiment, the rotating frame 4 includes a rotating bolt 401 and several positioning bolts 402. A crossbar on one side of the rotating frame 4 is located at the top of the slide frame 2. The crossbar of the rotating frame 4 is fixedly connected to the column of the rotating bolt 401. The column of the rotating bolt 401 is threadedly rotatably connected to the top of the slide frame 2.

[0022] When in use, rotating the rotating bolt 401 causes its column to drive the crossbar of the rotating frame 4 to rotate, thereby causing the rotating frame 4 to rotate around the axis of the rotating bolt 401. By rotating the rotating frame 4, its angle can be adjusted to adapt to automotive pipelines of different shapes and placement angles, providing a suitable position for subsequent testing of components. Operators can quickly adjust the angle of the rotating frame 4 according to the actual pipeline conditions, improving the convenience and versatility of testing.

[0023] In this embodiment, a drive cylinder 5 is provided on one side of the slide frame 2. The drive cylinder 5 is connected through to the square groove on one side of the rotating frame 4. Several positioning bolts 402 are threaded through to the two sides of the outside of the rotating frame 4. One end of the rod of the positioning bolt 402 abuts against the outer wall of the drive cylinder 5.

[0024] In use, the drive cylinder 5 is connected through to the square groove on one side of the rotating frame 4. By extending and retracting the drive cylinder 5, the dual-crystal probe 501 at its extension end can be sent into the pipeline body 6 to perform ultrasonic testing on the pipeline weld. The positioning bolt 402 is threaded through to both sides of the outside of the rotating frame 4. After the drive cylinder 5 is adjusted to the appropriate position, the positioning bolt 402 is tightened so that one end of its rod abuts against the outer wall of the drive cylinder 5, fixing the drive cylinder 5 and preventing it from shifting during the testing process. The drive cylinder 5 realizes the automatic extension and retraction of the dual-crystal probe 501, which can penetrate deep into the pipeline for testing, improving the comprehensiveness and accuracy of the testing.

[0025] In this embodiment, a pipeline body 6 is provided at the bottom of the drive cylinder 5, and the telescopic end of the drive cylinder 5 is slidably connected inside the pipeline body 6. A dual-crystal probe 501 is provided inside the pipeline body 6, and the dual-crystal probe 501 is fixedly connected to the bottom end of the telescopic end of the drive cylinder 5.

[0026] In use, the extension end of the drive cylinder 5 drives the dual-crystal probe 501 to move up and down inside the pipeline body 6. The dual-crystal probe 501 emits ultrasonic waves and receives the sound waves reflected back from the pipeline weld. Based on the characteristics of the reflected waves, it determines whether there are defects inside the weld, such as cracks or pores. Through the precise control of the drive cylinder 5, the welds at different locations in the pipeline can be fully inspected, realizing ultrasonic non-destructive testing of automotive pipeline welds. It can detect internal defects that are difficult to detect with the naked eye, ensuring the quality and safety of automotive pipelines.

[0027] In this embodiment, the main body of the pipeline 6 is located on the top of the base 1. A drive motor 102 is fixedly connected inside the base 1. A rotating seat 7 is provided on the top of the base 1. The bottom shaft of the rotating seat 7 passes through the base 1 and is fixedly connected to the output end of the drive motor 102. The rotating seat 7 includes an active clamping frame 701, a driven clamping frame 702, and a rubber ring 703.

[0028] In use, after the drive motor 102 starts, the output end drives the shaft at the bottom of the rotary table 7 to rotate, thereby rotating the rotary table 7. The active clamping frame 701 and the driven clamping frame 702 on the rotary table 7 clamp and fix the bottom end of the pipeline body 6. When the rotary table 7 rotates, it drives the pipeline body 6 to rotate together, so that the industrial camera 301 and the dual crystal probe 501 can perform all-round, no-dead-angle inspection of the weld seam during the rotation of the pipeline body 6. The rotation function of the rotary table 7, together with the industrial camera 301 and the dual crystal probe 501, realizes 360° comprehensive inspection of the automotive pipeline weld seam, avoiding the problem of missed inspection due to insufficient inspection angle.

[0029] In this embodiment, the inner rings of both the active clamping frame 701 and the driven clamping frame 702 are fixedly connected with rubber rings 703. The bottom end of the pipeline body 6 is located between the active clamping frame 701 and the driven clamping frame 702. The rubber rings 703 are attached to the outer wall of the bottom end of the pipeline body 6. The driven clamping frame 702 is fixedly connected to one side of the opening of the active clamping frame 701 by several bolts.

[0030] In use, the bottom end of the pipeline body 6 is placed between the active clamping frame 701 and the driven clamping frame 702. The driven clamping frame 702 is fixed to one side of the opening of the active clamping frame 701 with bolts, so that the two clamp the pipeline body 6 tightly. This ensures that the position of the pipeline body 6 is fixed during the inspection process, providing a stable inspection object for the industrial camera 301 to take pictures and the dual crystal probe 501 to inspect. The rubber ring 703 increases the friction and sealing of the clamping, preventing the pipeline body 6 from sliding or displacing during the inspection process. The use of the rubber ring 703 not only enhances the clamping effect, but also avoids damage to the surface of the pipeline body 6 during the clamping process, protecting the integrity of the pipeline.

[0031] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: Power is turned on, the control system is started, and detection parameters such as the shooting frequency of the industrial camera 301, the moving speed of the ultrasonic probe, and the rotation speed of the pipeline are set. The main body 6 of the pipeline to be tested is placed on the rotating seat 7 at the top of the base 1, so that the bottom end of the pipeline is located between the active clamping frame 701 and the driven clamping frame 702. The driven clamping frame 702 is tightened with bolts to clamp the pipeline with the active clamping frame 701. The inner ring rubber ring 703 is tightly attached to the outer wall of the pipeline to ensure a stable fixation without damaging the surface. Depending on the pipeline's placement angle, the rotating bolt 401 is manually rotated to drive the pipeline to rotate. The frame 4 rotates around its axis, aligning the drive cylinder 5 on the rotating frame 4 with the pipeline inlet. The positioning bolt 402 is tightened, and the rod of the positioning bolt 402 presses against the outer wall of the drive cylinder 5, fixing its position. The drive motor 101 inside the base 1 is then activated. The output of the drive motor 101 drives the lead screw 201 to rotate. The rotation of the lead screw 201 is converted into the vertical linear movement of the slide 3 along the slide frame 2, causing the industrial camera 301, fixed to one side of the slide 3, to move to the height of the pipeline weld. The industrial camera 301 takes multi-angle images of the pipeline weld surface, acquiring two-dimensional image data of the weld to detect surface defects such as cracks, undercut, and weld beads. Simultaneously, the drive cylinder 5 is activated. The cylinder extension end drives the dual-crystal probe 501 to extend from the square slot of the rotating frame 4, slowly extending it into the pipeline body 6 along the pipeline axis until it reaches the starting position of weld inspection. The dual-crystal probe 501 emits ultrasonic waves. When the sound waves encounter internal defects in the pipeline weld, such as porosity, lack of fusion, or slag inclusions, they generate reflected echoes. The probe receives the echo signals and transmits them to the control system, which drives the cylinder 5 to move the dual-crystal probe 501 up and down at a uniform speed along the pipeline weld direction to complete single-axis inspection. At the same time, the drive motor 102 inside the base 1 starts, driving the rotating seat 7 to rotate, causing the pipeline body 6 to rotate synchronously, realizing a spiral full-coverage scan of the weld. This device is driven by the mechanical transmission screw 201. The rotary table 7 enables motion control of the inspection components and pipelines. Combining the dual technologies of industrial camera 301 visual inspection and dual crystal probe 501 ultrasonic flaw detection, it forms a comprehensive inspection system of "surface + internal" and "static + dynamic" to ensure efficient and accurate assessment of the quality of automotive pipeline welds. In this solution, the control method of the electrical components is controlled by its matching peripheral controller, and the control circuit can be implemented by simple programming by those skilled in the art. It is common knowledge in the field and is used without modification. Furthermore, since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
