Description

Technical Field

[0001] This utility model relates to the field of weld penetration depth observation technology, specifically a weld penetration depth observation device that is easy to adjust. Background Technology

[0002] The weld penetration depth observation device is a professional equipment used to detect and measure the weld penetration depth during the welding process. It mainly observes the weld through the observation components and, together with the relevant adjustment mechanism, can clearly capture the weld penetration depth and display the observed image on the screen, so that operators or inspectors can intuitively understand whether the weld penetration depth meets the quality requirements. However, existing weld penetration depth monitoring devices still have certain problems in use: Traditional weld penetration observation devices mostly use fixed support structures, which cannot be flexibly adjusted according to the actual welding situation. This results in a limited observation range, making it difficult to meet the observation needs of different welding positions and angles. Moreover, the adjustment process is complicated and requires manual operation of multiple components, which not only leads to low adjustment efficiency but also makes it difficult to ensure the precise position of the observation head, affecting the accuracy of the observation results.

[0003] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0004] To address the aforementioned issues, an innovative design was developed based on the existing weld penetration depth observation device. Utility Model Content

[0005] The purpose of this invention is to provide a conveniently adjustable weld penetration observation device to solve the problems mentioned in the background art, which mostly use fixed support structures, cannot be flexibly adjusted according to the actual welding situation, resulting in a limited observation range, difficulty in meeting the observation needs of different welding positions and angles, and complicated adjustment process, requiring manual operation of multiple components, which not only has low adjustment efficiency, but also makes it difficult to ensure the precise position of the observation head, affecting the accuracy of the observation results.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A conveniently adjustable weld penetration observation device includes a base and a slide rail. The slide rail is welded to the top of the base, and a first slider is slidably connected to the top of the slide rail. A vertical rod is welded to the upper end of the first slider, and a horizontal bar is provided on one side of the vertical rod. A fixed seat is bolted to the top of the horizontal bar. Two sets of fixed plates are symmetrically welded to the middle of the fixed seat. A knob is provided on one side of the fixed plate, and a worm gear is fixed to the end of the knob, passing through and rotatably connected to the middle of the fixed plate. Limit shafts are fixed on both sides of the fixed seat. A movable seat is provided below the fixed seat, and a worm wheel that meshes with the worm gear is fixed in the middle of the movable seat. Second sliding grooves that are adapted to the limit shafts are opened on both sides of the movable seat, and a camera is bolted to the bottom of the movable seat.

[0007] By adopting the above technical solution, horizontal movement is achieved through the cooperation of the slide rail and the first slider. The worm gear and worm wheel meshing transmission, combined with the guide of the limiting shaft and the second slide groove, enable the movable seat to drive the camera to flexibly adjust its position and angle, which facilitates multi-directional and accurate observation of the weld penetration depth to meet the needs of penetration depth monitoring in different welding scenarios.

[0008] Preferably, the movable seat and the worm gear are in a semi-circular shape, and the outer side of the movable seat is provided with several scale bars.

[0009] Using the above technical solution, the movable seat and worm gear are designed in a semi-circular structure, which can cooperate with the worm to achieve a rotating motion with an arc trajectory. The scale bar establishes a quantitative reference for the rotational displacement by marking angle values. The semi-circular structure allows the camera to make a wide range of angle adjustments around the center axis. The scale bar can accurately display the rotation angle, which makes it easy for operators to quickly locate the observation angle and ensure repeatability accuracy.

[0010] Preferably, the second slide groove has an arc-shaped structure, and the limiting shaft is slidably connected to the second slide groove.

[0011] Using the above technical solution, the second slide is designed as an arc-shaped structure and is slidably connected to the limiting shaft. When the worm gear drive drives the movable seat to rotate, the limiting shaft slides in the arc-shaped slide, constraining and guiding the rotation trajectory of the movable seat. The arc-shaped second slide cooperates with the limiting shaft to ensure that the movable seat can rotate stably along the predetermined arc path, realize the precise adjustment of the camera angle, and prevent the movable seat from deviating or derailing during rotation.

[0012] Preferably, the end of the worm gear is provided with a threaded coil, and a limiting nut adapted to the threaded coil is sleeved on the end of the worm gear.

[0013] Using the above technical solution, a threaded coil is set at the end of the worm and a limiting nut is sleeved on it. Through the self-locking characteristic of the thread structure, the limiting nut can form an adjustable mechanical block in the worm's axial direction. When the limiting nut is rotated to a specific position, the axial movement range of the worm can be limited, preventing the components from dislodging due to backlash or external force during the worm gear transmission. At the same time, the boundary setting of the rotation angle of the movable seat can be achieved by adjusting the position of the nut.

[0014] Preferably, a stepper motor is bolted to one side of the slide rail, and a lead screw is movably connected to the output end of the stepper motor, with the lead screw passing through and threadedly connected to the middle of the first slider.

[0015] Using the above technical solution, the stepper motor achieves fine-grained control of the rotation angle through precise control pulse signals. Its output drives the lead screw to rotate, and the rotational motion is converted into linear motion by the threaded engagement between the lead screw and the first slider. This drives the slider to move directionally along the slide rail, achieving millimeter-level displacement control of the first slider on the slide rail. In turn, this enables the camera of the observation device to perform automated and programmable horizontal position adjustment, improving the flexibility and repeatability of weld penetration observation.

[0016] Preferably, a first sliding groove is provided in the middle of the upright, a cylinder is bolted to the top of the first sliding groove, a second slider is fixed to the output end of the cylinder, and one end of the crossbar is fixedly connected to the second slider.

[0017] Using the above technical solution, the cylinder generates linear thrust through compressed air, and its output end drives the second slider to slide vertically in the first groove in the middle of the upright, thereby driving the crossbar fixed to the second slider to achieve lifting and lowering movement, realizing the automatic vertical height adjustment of the camera of the observation device, meeting the needs of weld depth observation at different heights, and improving adjustment efficiency and accuracy.

[0018] Preferably, an observation platform is provided on the upper surface of the base, and the camera is located directly above the observation platform. Support feet are installed at the four corners of the bottom of the base, and a control panel is installed on the outer side of the base.

[0019] By adopting the above technical solution, the camera is placed directly above the observation platform. The vertical layout ensures that the shooting angle is perpendicular to the weld plane. The support feet provide stable support and the height of the base can be adjusted. The control panel integrates the control circuits of components such as motors and cylinders to achieve centralized operation. This allows the camera to clearly and accurately capture images of weld penetration depth. The support feet ensure stable operation of the equipment, and the control panel allows operators to quickly adjust the position of the device and the angle of the camera according to the observation needs, thereby improving detection efficiency and accuracy.

[0020] Compared with the prior art, the beneficial effects of this utility model are: this easily adjustable weld penetration observation device... 1. The four support feet at the bottom of the base ensure stable placement of the device, providing a reliable foundation for observation; the slide rail cooperates with the first slider, and when the stepper motor drives the lead screw to rotate, the horizontal position of the first slider can be precisely adjusted according to the lead screw transmission principle, thereby flexibly adjusting the horizontal direction of the camera, facilitating the observation of welds at different horizontal positions on the observation platform; the camera is located directly above the observation platform, allowing direct imaging of the weld; the control panel is designed to facilitate operators in controlling components such as the stepper motor, enabling rapid and precise adjustments, effectively improving observation efficiency and accuracy, and meeting diverse weld penetration observation needs; 2. A vertical support rod is welded to the upper end face of the first slider, providing a stable vertical support structure for the crossbar. A first groove is opened in the middle of the vertical support rod and connected to a cylinder. When the cylinder is activated, its output end drives the second slider to make a vertical linear movement within the first groove. Since one end of the crossbar is fixed to the second slider, the crossbar can be raised and lowered vertically. This design allows the camera mounted on the crossbar to be flexibly adjusted in the vertical direction, quickly adapting to the observation needs of welds at different heights. It eliminates the need for cumbersome manual operation, greatly improving the convenience and efficiency of observation, while also enhancing the accuracy of observation, ensuring the acquisition of the optimal observation angle and images of weld penetration depth. 3. The bolted top of the crossbar connects to the fixed base, providing a stable foundation for the overall adjustment structure. Rotating the knob on one side of the fixed plate drives the worm gear to rotate. Utilizing the worm gear transmission principle, it can smoothly drive the semi-circular movable seat to rotate, thereby flexibly changing the shooting angle of the bottom camera to meet the observation needs of weld penetration at different angles. The limiting shafts on both sides of the fixed base slide against the second arc-shaped grooves on both sides of the movable seat, effectively limiting the rotation trajectory of the movable seat, preventing its deviation, and ensuring rotational stability. The scale bar on the outside of the movable seat can accurately display the rotation angle, making it convenient for operators to precisely adjust the camera angle. The threaded coil at the end of the worm gear cooperates with the limiting nut to prevent dislocation during worm gear transmission, further improving the reliability and stability of the device and ensuring smooth observation work.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1 Please see Figure 1 , Figure 2 This utility model provides a technical solution: An easily adjustable weld penetration observation device includes a base 1 and a slide rail 4. The slide rail 4 is welded to the top of the base 1, and a first slider 5 is slidably connected to the top of the slide rail 4. A stepper motor 6 is bolted to one side of the slide rail 4, and a lead screw 7 is movably connected to the output end of the stepper motor 6, with the lead screw 7 passing through and threaded into the middle of the first slider 5. An observation platform 2 is provided on the upper surface of the base 1, and a camera 23 is located directly above the observation platform 2. Support feet 3 are installed at the four corners of the bottom of the base 1, and a control panel 24 is installed on the outer side of the base 1.

[0025] This easily adjustable weld penetration observation device uses a base 1 as its basic support structure. Support feet 3 at the four corners of the base provide stable support, ensuring the device is placed stably. A slide rail 4 is welded above the base 1, providing a sliding track for the first slider 5. A stepper motor 6 is bolted to one side of the slide rail 4, serving as the power source. Its output is movably connected to a lead screw 7. When the stepper motor 6 starts, it drives the lead screw 7 to rotate. Since the lead screw 7 passes through and is threaded into the middle of the first slider 5, according to the transmission principle of the lead screw 7, its rotation is converted into linear sliding of the first slider 5 on the slide rail 4, thus achieving precise adjustment of the horizontal position of the first slider 5. An observation platform 2 is set on the upper surface of the base 1 to place the workpiece to be observed. A camera 23 located directly above the observation platform 2 can capture and observe the weld penetration. A control panel 24 installed on the outside of the base 1 controls the start / stop, speed, and direction of the stepper motor 6, thereby controlling the movement of the first slider 5 and facilitating the adjustment of the position of the camera 23 relative to the weld on the observation platform 2 to obtain the optimal observation angle and effect.

[0026] Example 2 Please see Figure 3 This utility model provides a technical solution: A vertical rod 8 is welded to the upper end of the first slider 5, and a horizontal bar 12 is provided on one side of the vertical rod 8. A first sliding groove 9 is provided in the middle of the vertical rod 8, and a cylinder 10 is bolted to the top of the first sliding groove 9. A second slider 11 is fixed to the output end of the cylinder 10, and one end of the horizontal bar 12 is fixedly connected to the second slider 11.

[0027] This easily adjustable weld penetration observation device uses a vertical rod 8 welded to the upper end of the first slider 5 as a vertical support structure. The first groove 9 in the middle provides a vertical track for the second slider 11. The cylinder 10, bolted to the top of the first groove 9, serves as a power element. When the cylinder 10 is activated, its output end will perform a linear extension and retraction motion. Since the output end of the cylinder 10 is fixed to the second slider 11, and one end of the crossbar 12 is fixedly connected to the second slider 11, according to the transmission principle of the cylinder 10, the linear motion of the output end of the cylinder 10 will drive the second slider 11 to slide vertically in the first groove 9, thereby driving the crossbar 12 to achieve vertical lifting and lowering. This allows the camera 23 installed on the crossbar 12 to be adjusted in the vertical direction, making it convenient to quickly and accurately adjust the height of the observation equipment according to the observation needs of welds at different heights, so as to obtain the best weld penetration observation angle and effect.

[0028] Example 3 Please see Figure 4 , Figure 5 This utility model provides a technical solution: A fixed seat 13 is bolted to the top of the crossbar 12. Two sets of fixed plates 14 are symmetrically welded to the middle of the fixed seat 13. A knob 15 is provided on one side of the fixed plate 14. A worm gear 16, which passes through and is rotatably connected to the middle of the fixed plate 14, is fixed to the end of the knob 15. Limiting shafts 17 are fixed on both sides of the fixed seat 13. A movable seat 18 is provided below the fixed seat 13. A worm wheel 19, which meshes with the worm gear 16, is fixed in the middle of the movable seat 18. Second sliding grooves 20, which are adapted to the limiting shafts 17, are opened on both sides of the movable seat 18. A camera 23 is bolted to the bottom of the movable seat 18. The movable seat 18 and the worm wheel 19 are in a semi-circular structure, and several scale strips are provided on the outer side of the movable seat 18. The second sliding groove 20 is arc-shaped, and the limiting shafts 17 are slidably connected to the second sliding groove 20. The end of the worm 16 is provided with a threaded coil 21, and a limiting nut 22 adapted to the threaded coil 21 is sleeved on the end of the worm 16.

[0029] This easily adjustable weld penetration observation device uses a fixed base 13 bolted to the top of the crossbar 12 as a supporting foundation for the overall adjustment structure. Two sets of symmetrically welded fixed plates 14 in the middle are used to mount the worm gear 16. When the knob 15 on one side of the fixed plate 14 is rotated, the worm gear 16 fixed at its end rotates in the middle of the fixed plate 14. Since the worm wheel 19 in the middle of the movable seat 18 meshes with the worm gear 16, according to the transmission principle of the worm wheel 19 and worm gear 16, the rotation of the worm gear 16 drives the worm wheel 19 to rotate, thereby causing the semi-circular movable seat 18 to rotate. The limiting shafts 17 on both sides of the fixed base 13 and the movable seat 18 have an arc-shaped structure. The second slide groove 20 provides a sliding connection and guides and limits the rotation of the movable seat 18, ensuring that the movable seat 18 can only rotate along an arc trajectory. The scale bar on the outside of the movable seat 18 can accurately display its rotation angle, facilitating precise adjustment by the operator. The threaded coil 21 at the end of the worm 16 cooperates with the sleeved limit nut 22. By rotating the limit nut 22, the axial movement of the worm 16 can be restricted, preventing dislocation of the worm wheel 19 and worm 16 during transmission. The camera 23 bolted to the bottom of the movable seat 18 can change its shooting angle as the movable seat 18 rotates, thereby enabling flexible and accurate observation of the weld penetration depth at different angles.

[0030] Working principle: In operation, the base 1 provides stable support for the entire structure. The control panel 24 controls the stepper motor 6 to start, and its output drives the lead screw 7 to rotate. Based on the transmission principle of the lead screw 7, the first slider 5 slides horizontally on the slide rail 4 to adjust its horizontal position. The cylinder 10 at the top of the upright rod 8 on the first slider 5 is activated, and its output performs a linear extension and retraction motion, driving the second slider 11 to slide vertically in the first slide groove 9, thereby causing the crossbar 12 to rise and fall vertically to adjust the observation height. Rotating the knob 15 on one side of the fixing plate 14 on the top fixing seat 13 of the crossbar 12 drives the worm gear 16 to rotate, according to... The worm gear 19 and worm 16 drive the worm gear 19 and the semi-circular movable seat 18 to rotate. The limiting shafts 17 on both sides of the fixed seat 13 slide within the arc-shaped second slide grooves 20 on both sides of the movable seat 18, serving as guides and limits. The scale bar on the outer side of the movable seat 18 displays the rotation angle for easy and precise adjustment. At the same time, the limiting nut 22 at the end of the worm 16 cooperates with the threaded coil 21 to prevent the worm gear 19 and worm 16 from dislodging. Finally, the movable seat 18 drives the bottom camera 23 to change the shooting angle, enabling flexible and precise observation of the weld penetration depth at different positions, heights, and angles.
