Description

Technical Field

[0001] This invention relates to the field of pipeline inspection technology, and in particular to a heat-resistant and wear-resistant device for detecting the angle of bent and straight pipes and its usage method. Background Technology

[0002] Wear-resistant and heat-resistant straight pipes, also known as elbows or bend connectors, primarily serve to connect two parts in different orientations. Normally, after straight pipe processing, sampling inspection is required to quickly and accurately check its bending angle, straight section length, and the flatness of the pipe sidewalls. This is a crucial step in ensuring product quality and interchangeability.

[0003] In the prior art, the heat-resistant and wear-resistant curved and straight pipe angle sampling and measurement device disclosed in patent number CN222964583U, although designed with a method of rapid comparison through a pre-set groove corresponding to the curved and straight pipe and a spring-driven detection component, simplifies the traditional purely manual measurement process, still has several areas for optimization. In actual use, the judgment of the test results mainly relies on the operator's visual observation from top to bottom to see if the detection plate fits the pipe body, and on the feeling to judge whether the detection component is loose. This subjective judgment method is prone to misjudgment when faced with excessive spring pressure, slight vibration, or visual errors, and the detection accuracy and consistency need to be improved. In addition, in terms of the detection process, the tested sample must be manually removed first, and then the sample to be tested must be placed in. The unloading and loading processes cannot be synchronized, which limits the improvement of sampling efficiency. At the same time, its structure has a relatively fixed range of adaptability to the diameter of curved and straight pipes. When testing products with different pipe diameters, new components need to be replaced to adapt to different pipe diameter products. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art, and to propose a heat-resistant and wear-resistant bending and straight pipe angle detection device and its usage method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A heat-resistant and wear-resistant bending and straight pipe angle detection device includes a base plate and further includes: A detection seat, which is vertically mounted on a base plate, has an arc-shaped groove on it; A track frame, which is located on the outside of the testing seat, is used to accommodate the straight or bent pipe body during testing; A pushing component is disposed on one side of the detection seat and is used to push the straight pipe body to be detected into the track frame. And a material discharge channel, which is located on the lower side of the track frame; The detection seat is equipped with an adjustment component for adjusting the size of the track frame.

[0006] Preferably, the track frame includes an arc-shaped plate and an adjustable elastic plate disposed on the upper side of the arc-shaped plate, wherein the top wall of the arc-shaped plate and the bottom wall of the adjustable elastic plate together form a detection slot for accommodating the straight pipe body; The arc-shaped plate is slidably connected within the arc-shaped groove, and the adjustable elastic plate is connected to the adjustment assembly.

[0007] Preferably, the adjustment assembly includes a first support plate fixed on the detection seat, a first screw rotatably connected to the first support plate, a first sleeve threadedly connected to the first screw, a sleeve fixedly connected to the first sleeve and sleeved on the outside of the first screw, and a first connecting ball disposed at the bottom of the sleeve, wherein the first connecting ball is movably disposed within an adjustable elastic plate. It also includes a second support plate fixed on the detection seat, a second screw rotatably connected to the second support plate, a second sleeve threadedly connected to the second screw, a swing rod rotatably connected to both sides of the second sleeve via a pin, and a slider movably connected to the end of the swing rod away from the second sleeve. The adjustable elastic plate is provided with a groove for the slider to slide.

[0008] Preferably, the pushing component includes elastic telescopic rods fixed on both sides of the detection seat, a movable plate disposed between the two elastic telescopic rods, a movable rod fixedly connected to the movable plate, and a pushing plate connected to the movable rod. The pushing plate moves against the straight pipe body in the detection slot, and the movable rod is fixedly connected to the arc plate through a connecting plate.

[0009] Preferably, the push plate includes a central plate connected to the moving rod and side plates rotatably disposed on both sides of the central plate via a rotating shaft; The movable rod includes a straight rod fixedly connected to the movable plate and a second connecting ball disposed at the end of the straight rod, the second connecting ball being movably disposed within the central plate.

[0010] Preferably, a plurality of L-shaped rods are fixed on the detection seat, and each L-shaped rod is provided with an auxiliary support plate parallel to the top wall of the arc plate. The arc plate is provided with a movable groove that cooperates with the auxiliary support plate. A material dropping area for the straight tube body to fall is formed between the end of the auxiliary support plate away from the L-shaped rod and the detection seat. The adjustable elastic plate is provided with a limiting support plate that cooperates with the auxiliary support plate. The auxiliary support plate and the limiting support plate together form a channel corresponding to the straight pipe body.

[0011] Preferably, the pushing assembly further includes a fixed tube fixedly connected to the moving rod via a connecting rod, a movable rod slidably connected within the fixed tube, a hinge rod hinged between the movable rod and the side plate, and a compression spring disposed at the end of the movable rod away from the hinge rod, wherein the end of the compression spring away from the movable rod is fixedly connected to the moving plate. The fixed tube has a groove, the movable rod has a displacement scale line that matches the groove, and the fixed tube also has a standard arrow pointing to the displacement scale line.

[0012] Preferably, a baffle plate is fixed on the base plate and arranged parallel to the detection seat. A rotating shaft is rotatably arranged between the baffle plate and the detection seat. A flipping plate is arranged on the rotating shaft. Guide plates that cooperate with the flipping plate are arranged on both sides of the base plate. The material discharge channel is composed of a channel formed by the baffle plate, the flipping plate and the detection seat.

[0013] Preferably, measuring plates are provided on both sides of the detection seat, each measuring plate is arranged parallel to the horizontal plane of the arc plate, and the measuring plates are provided with measuring scale lines for detecting the straight pipe length of the bent pipe body.

[0014] This invention also discloses a method for using a heat-resistant and wear-resistant bending and straight pipe angle detection device, comprising the following steps: S1: According to the pipe diameter specifications of the straight and bent pipe body to be inspected, manually rotate the first screw and the second screw to drive the first sleeve and the second sleeve to move respectively. The first sleeve adjusts the center height position of the adjustable elastic plate through the sleeve and the first connecting ball. The second sleeve slides in the groove through the swing rod and the slider, and together adjusts the distance and curvature of the adjustable elastic plate relative to the lower arc plate, thereby forming a detection groove suitable for the current pipe diameter. S2: Then pull the moving plate outward to overcome the elastic force of the elastic telescopic rod and move it away from the detection seat. On the one hand, it drives the push plate away from the track frame, and on the other hand, it pulls the arc plate to slide horizontally relative to the auxiliary support plate through the connecting plate, so that a discharge port is formed between the end of the auxiliary support plate and the detection seat. S3: Then place the straight pipe body to be tested into the channel formed by the auxiliary support plate and the limiting support plate on the adjustable elastic plate; A preliminary screening is conducted here: if the tube angle deviation is large or the shape is not up to standard, it will not be able to be successfully placed into this channel and can be directly judged as a defective product. S4: Then release the moving plate. Under the elastic force of the elastic telescopic rod, the moving plate resets and pushes the moving rod forward. The moving rod pushes the arc plate to reset through the connecting plate and slides back to the bottom of the adjustable elastic plate to provide bottom support for the straight pipe body. At the same time, the push plate, pushed by the moving rod, pushes the bent pipe body forward along the channel formed by the auxiliary support plate and the limiting support plate until the bent pipe body and the detection seat are in close contact. S5: Multi-dimensional inspection can be performed after the straight or bent pipe body comes into contact with the inspection seat. Straight pipe length inspection: Observe whether the ends of the straight pipe sections at both ends of the straight pipe body are within the qualified range of the measuring scale lines on both sides of the measuring plate of the inspection seat; Side flatness inspection: The composite structure consisting of a central plate of the push plate and two rotatable side plates can adaptively fit the side of the bent pipe. If the side of the bent pipe is on the same plane, the two side plates will not deflect. Through the linkage mechanism consisting of a hinge rod, a movable rod, and a compression spring, the standard arrow on the fixed pipe points to the zero mark of the displacement scale on the movable rod. At this time, the compression spring is in a compressed state. If the side of the bent pipe body is not flat, the side plates will deflect. The hinge rod pushes / pulls the movable rod to move it, so that the standard arrow points to a non-zero mark. The value is the flatness deviation. S6: Based on the detection results of step S5, the operator controls the rotation of the rotating shaft to adjust the tilt direction of the flip plate; When performing the next inspection, repeat step S2. At this time, the arc plate moves backward, and the straight pipe body that has been inspected loses its bottom support. Under the action of gravity, it automatically falls through the material drop channel and slides into the corresponding guide plate along the flip plate with the set direction, realizing automatic material feeding and automatic sorting.

[0015] Compared with the prior art, the present invention provides a heat-resistant and wear-resistant bending and straight pipe angle detection device and its usage method, which has the following beneficial effects: 1. In this invention, by setting measuring plates with measuring scale lines on both sides of the testing seat, the length of the straight pipes on both sides of the bent pipe body can be directly and accurately measured, providing an objective basis for judging the length dimension. This avoids the reading errors in traditional caliper measurements. Furthermore, the testing mechanism, composed of a deflectable side plate, a hinged rod, a movable rod, and displacement scale lines, can amplify and convert the flatness deviation of the bent pipe side, which is difficult to observe with the naked eye, into a readable displacement scale value through the mechanical lever principle. This achieves quantitative detection of the angle and shape errors of the bent pipe, so that the test results no longer depend on the operator's subjective feel and experience judgment, fundamentally eliminating the risk of misjudgment due to human factors, and significantly improving the accuracy, reliability, and batch consistency of the sampling results.

[0016] 2. In this invention, by setting up a pushing component, when the moving plate is pulled outward, this single action can simultaneously drive the pushing plate to move backward (to make room for loading) and the arc plate to retract (to open the dropping port); conversely, when the moving plate is released, under the action of the elastic telescopic rod, the moving rod sequentially drives the arc plate to reset (to provide support for the bent pipe) and the pushing plate to move forward (to complete the pushing and contact detection). This simple pull and release operation seamlessly connects the three steps of loading, pushing and positioning, and unloading. The next loading action automatically triggers the falling of the previously inspected workpiece, realizing the synchronous operation of detection and unloading, forming an efficient continuous operation cycle, avoiding the interruption of the process of "detection-manual removal-reloading" in the traditional method, greatly shortening the single-piece detection cycle and significantly improving the overall detection efficiency.

[0017] 3. In this invention, rotating the first screw drives the first sleeve and tube to move up and down, thereby adjusting the overall support height of the adjustable elastic plate. Simultaneously, rotating the second screw drives the second sleeve to move up and down, and through the swing rods and slider mechanism on both sides, the bending arc and opening / closing state of the adjustable elastic plate on both sides are adjusted in conjunction. The two work together to flexibly and continuously adjust the size of the detection slot formed by the arc plate and the adjustable elastic plate, so as to accurately adapt to the straight and bent pipes of different outer diameters. Thus, one device can cover multiple product models without the need to customize or replace special inspection tools for each specification, which greatly enhances the versatility of the equipment and the adaptability of the production line, and reduces the equipment investment and replacement costs.

[0018] 4. In this invention, after the inspection is completed, the operator can quickly determine whether the product is qualified or not based on the reading of the measuring plate and the indication of the displacement scale line. The operator can also manually (or through the actuator) adjust the angle of the flipping plate on the rotating shaft. When the next inspection cycle begins and the moving plate is pulled to make the arc plate retreat, the inspected workpiece will automatically fall and slide into the corresponding left or right guide plate channel along the flipping plate in the preset direction, thereby automatically completing the physical sorting of qualified and unqualified products. By integrating the three processes of inspection, judgment and sorting into one, not only is the workload of subsequent manual sorting reduced and the risk of mixing due to human negligence avoided, but also the automated connection for the isolation and rework of unqualified products and the circulation of qualified products is directly provided, thus optimizing the overall quality management process.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0023] like Figures 1 to 4 As shown, this embodiment proposes a heat-resistant and wear-resistant bent and straight pipe angle detection device, including a base plate 1, and further including: a detection seat 2, a track frame 3, a pushing component, and a material discharge channel; the detection seat 2 is vertically arranged on the base plate 1, and an arc-shaped groove 201 is opened on the detection seat 2; the track frame 3 is arranged on the outside of the detection seat 2 for accommodating the bent and straight pipe body 4 under detection; the pushing component is arranged on one side of the detection seat 2 for pushing the bent and straight pipe body 4 to be detected into the track frame 3; the material discharge channel is arranged on the lower side of the track frame 3; wherein, the detection seat 2 is provided with an adjustment component for adjusting the accommodating size of the track frame 3 to adapt to bent and straight pipe products of different pipe diameters or size specifications; Specifically, based on the specifications of the straight pipe body 4 to be tested, the adjustment component is operated to adjust the accommodating shape of the track frame 3 so that the accommodating space formed by it and the testing seat 2 is adapted to the product size. The straight pipe body 4 to be tested is initially placed in the entrance area between the testing seat 2 and the track frame 3. The pushing component is activated, and the pushing component moves to smoothly push the straight pipe body 4 into the testing station in the horizontal direction. In this positioning state, the operator can perform the test. The judgment criteria are: a qualified straight pipe should have a bending arc that matches the arc-shaped station formed by the track frame 3 and can be neatly accommodated by the track frame 3. If it cannot be pushed into place, cannot fit, or is obviously misaligned, it can be judged as unqualified. After the test is completed, by removing the pushing component, the workpiece under test loses its bottom support and automatically slides out through the lower material drop channel under the action of gravity, completing one test cycle. This avoids the interruption of the process of "testing-manual removal-reloading" in the traditional method, greatly shortens the single-piece test cycle, significantly improves the overall test efficiency, reduces the labor intensity of the operator, and helps to ensure the stability and accuracy of the test process.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in a preferred embodiment, based on the above method, the track frame 3 further includes an arc-shaped plate 301 and an adjustable elastic plate 302 disposed on the upper side of the arc-shaped plate 301. The top wall of the arc-shaped plate 301 and the bottom wall of the adjustable elastic plate 302 together form a detection slot for accommodating the bent pipe body 4. The arc-shaped plate 301 provides an accurate bottom arc-shaped support reference for the bent pipe, ensuring the core positioning of the bending angle. The adjustable elastic plate 302 above provides an upward pressing or blocking effect on the pipe body. The detection slot formed by the two can constrain the bent pipe body 4 from both the top and bottom directions, effectively preventing it from shaking or shifting during the detection process, ensuring the stability and repeatability of the detection state, and laying the foundation for accurate measurement. The adjustable elastic plate 302 can be a metal elastic plate. The arc-shaped plate 301 is slidably connected in the arc-shaped groove 201, and the adjustable elastic plate 302 is connected to the adjustment component; Furthermore, the adjustment assembly includes a first support plate 6 fixed on the detection seat 2, a first screw 601 rotatably connected to the first support plate 6, a first sleeve 602 threadedly connected to the first screw 601, a sleeve 603 fixedly connected to the first sleeve 602 and sleeved on the outside of the first screw 601, and a first connecting ball 604 disposed at the bottom of the sleeve 603. The first connecting ball 604 is movably disposed within the adjustable elastic plate 302. It also includes a second support plate 7 fixed on the detection seat 2, a second screw 701 rotatably connected to the second support plate 7, a second sleeve 702 threadedly connected to the second screw 701, a swing rod 703 rotatably connected to both sides of the second sleeve 702 by a pin, and a slider 704 movably connected to the end of the swing rod 703 away from the second sleeve 702. The adjustable elastic plate 302 is provided with a groove 3021 for sliding the slider 704. Specifically, by rotating the first screw 601, the first sleeve 602 moves axially along the first screw 601, which in turn drives the sleeve 603 and the first connecting ball 604 to move along the axial direction of the first screw 601. The first connecting ball 604 is connected to the adjustable elastic plate 302 via a ball joint, driving the adjustable elastic plate 302 to move up and down, thereby adjusting the gap between its bottom surface and the top surface of the lower arc-shaped plate 301. By rotating the second screw 701, the second sleeve 702 moves axially along the second screw 701. During this movement, the second sleeve 702 is converted into two sliders 704 via the swing rods 703 on both sides, moving in the groove 3. Within 021, the sliding of slider 704 forces the two sides of adjustable elastic plate 302 to move closer or further apart with the middle as the fixed point, thereby finely adjusting the curvature of its working surface. This allows it to better match the upper surface of bent pipes with different bending radii, or adjust the containment state of irregular pipe bodies. As a result, it can more perfectly adapt to various bent and straight pipe products with different combinations of curvature radii and pipe diameters, achieving multi-parameter, high-precision adaptive adjustment. This allows one device to cover multiple product models without the need to customize or replace special inspection tools for each specification, greatly enhancing the versatility of the equipment and the adaptability of the production line, and reducing equipment investment and replacement costs.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 8 and Figure 10 As shown, in a preferred embodiment, based on the above method, the pushing component further includes elastic telescopic rods 5 fixed on both sides of the detection seat 2, a movable plate 501 disposed between the two elastic telescopic rods 5, a movable rod 502 fixedly connected to the movable plate 501, and a pushing plate 503 connected to the movable rod 502. The pushing plate 503 moves against the bent and straight pipe body 4 in the detection slot, and the movable rod 502 is fixedly connected to the arc plate 301 through the connecting plate 5023. Specifically, the operator manually pulls the moving plate 501 outward, away from the testing station. This action overcomes the contraction force of the elastic telescopic rod 5, causing the moving plate 501 to move backward along with the moving rod 502 fixedly connected to it. The moving rod 502 then pulls the push plate 503 at its end backward, exiting the testing slot to allow the insertion of a new curved or straight pipe body 4 to be tested. Through the transmission of the connecting plate 5023, the arc-shaped plate 301 is simultaneously pulled backward, sliding backward along the arc-shaped groove 201 on the testing seat 2, thereby opening the bottom support of the testing slot; the workpiece is then placed in the slot. After the operation, the operator releases the movable plate 501. Under the restoring force of the elastic telescopic rod 5, the movable plate 501 is pushed forward to reset. The movable rod 502 pushes the arc plate 301 along the arc groove 201 to reset and slide back to its working position through the connecting plate 5023, providing bottom support for the bent pipe body 4 again. As the movable rod 502 continues to move forward, the push plate 503 abuts against the bent pipe body 4 and pushes it smoothly and reliably into the depth of the detection groove formed by the arc plate 301 and the adjustable elastic plate 302 until it is fully in contact with the detection seat 2, completing the detection positioning.

[0026] like Figure 1 , Figure 3 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, in a preferred embodiment, based on the above method, the push plate 503 further includes a central plate 5031 connected to the moving rod 502 and side plates 5032 rotatably disposed on both sides of the central plate 5031 via a pivot. If the end face of the bent tube is not a perfect plane, for example, there is a case of non-coplanarity, the side plates 5032 on both sides can be independently deflected around their pivot. The movable rod 502 includes a straight rod 5021 fixedly connected to the movable plate 501 and a second connecting ball 5022 disposed at the end of the straight rod 5021. The second connecting ball 5022 is movably disposed within the center plate 5031. Furthermore, several L-shaped rods 10 are fixed on the detection seat 2. Each L-shaped rod 10 is provided with an auxiliary support plate 1001 parallel to the top wall of the arc plate 301. The arc plate 301 is provided with a movable groove 3011 that cooperates with the auxiliary support plate 1001. The end of the auxiliary support plate 1001 away from the L-shaped rod 10 forms a dropping zone between it and the detection seat 2 for the straight tube body 4 to fall. When the arc plate 301 retracts to receive material, its action automatically opens the dropping zone, creating conditions for the automatic fall of the previous inspected workpiece. The adjustable elastic plate 302 is provided with a limiting support plate 3022 that cooperates with the auxiliary support plate 1001. The auxiliary support plate 1001 and the limiting support plate 3022 together form a channel corresponding to the bent pipe body 4. Before the bent pipe body 4 is pushed, the operator places the bent pipe body 4 to be tested in the channel formed by the auxiliary support plate 1001 and the limiting support plate 3022. This channel plays a preliminary guiding, supporting and radial limiting role for the workpiece. Furthermore, the pushing component also includes a fixed tube 8 fixedly connected to the moving rod 502 via a connecting rod, a movable rod 9 slidably connected within the fixed tube 8, a hinge rod 901 hinged between the movable rod 9 and the side plate 5032, and a compression spring 902 disposed at the end of the movable rod 9 away from the hinge rod 901, the end of the compression spring 902 away from the movable rod 9 being fixedly connected to the moving plate 501. The fixed tube 8 has a groove 801, the movable rod 9 has a displacement scale line that matches the groove 801, and the fixed tube 8 also has a standard arrow 802 for pointing to the displacement scale line. Specifically, when the entire pushing component is pulled or released, the fixed tube 8 moves together with the moving rod 502. When the pushing plate 503 is positioned against the end face of the bent tube body 4, if the side plates 5032 on both sides of the bent tube deflect due to uneven end faces, this deflection movement will be transmitted to the movable rod 9 through the hinge rod 901, pushing or pulling the movable rod 9 to generate axial sliding displacement within the fixed tube 8. The sliding of the movable rod 9 will cause the displacement scale line on its surface to move relative to the fixed standard arrow 802. The operator can directly read the scale value indicated by the standard arrow 802 through the groove 801. This scale value directly reflects the deflection of the side plate 5032, thereby quantifying the flatness deviation of the bent tube end face. This achieves rapid, objective, and quantitative online detection, filling the functional gap of traditional angle gauges, and eliminating the subjectivity and uncertainty caused by relying on touch, sound, or visual estimation, greatly improving the scientific nature, consistency, and traceability of quality judgment.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment, based on the above method, a baffle 11 is fixed on the base plate 1 and arranged parallel to the detection seat 2. A rotating shaft 12 is rotatably arranged between the baffle 11 and the detection seat 2. A flip plate 121 is arranged on the rotating shaft 12. Guide plates 122 that cooperate with the flip plate 121 are arranged on both sides of the base plate 1. The material discharge channel is composed of the channel formed by the baffle 11, the flip plate 121 and the detection seat 2. Specifically, before starting the detection process, the operator separates the qualified products and unqualified products to both sides according to requirements, and manually or rotates the rotating shaft 12 through a driving mechanism. The driving mechanism can be a motor, so as to set the inclination direction of the turning plate 121. For example, lower the left side of the turning plate 121 so that it points to the guiding plate 122 on the left; or lower its right side to point to the guiding plate 122 on the right. When the bent straight pipe body 4 that has completed the detection falls from above into the blanking channel formed by the baffle 11, the turning plate 121 and the detection seat 2, the workpiece slides down along the channel under the action of gravity. Since the turning plate 121 is inclined, after the workpiece contacts its surface, it will naturally slide to the lower inclined place. The workpiece sliding out from the lower end of the turning plate 121 will continue to fall onto the corresponding guiding plate 122 on one side, and then be conveyed to the designated collection box or subsequent workstations, realizing the diversion in the preset direction. The blanking channel is a guiding surface surrounded by the surfaces of three fixed or movable parts, so that the falling workpiece is restricted in three directions, which can effectively prevent the workpiece from tumbling, bouncing or jamming during the falling process, ensuring that it slides towards the sorting plate in a controllable posture and trajectory, thus ensuring the smoothness, order and efficiency of the entire blanking and sorting process.

[0028] As Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, as a preferred embodiment, on the basis of the above method, further, measuring plates 13 are provided on both sides of the detection seat 2. Each measuring plate 13 is arranged parallel to the horizontal plane of the arc-shaped plate 301, and measuring scale lines for detecting the straight pipe length of the bent straight pipe body 4 are provided on the measuring plate 13. Specifically, after the bent straight pipe body 4 is completely pushed in place by the pushing component and its bent part abuts against the inner wall of the detection seat 2, the entire workpiece is in a determined detection position. At this time, the straight pipe segments on both sides of the bent straight pipe body 4 extend horizontally, and their ends respectively point to the measuring plates 13 on both sides. The operator directly observes the scale position where the end of the straight pipe segment of the bent straight pipe body 4 is located on the measuring scale line of the corresponding measuring plate 13 on that side. By reading this scale value, the actual extended length of the straight pipe segment on that side can be directly obtained. Compare the measured values of the straight pipe lengths on both sides read with the standard length and tolerance range specified in the product drawing or process requirements. If the length values on both sides are within the tolerance band, the dimension of this item is qualified; if any side exceeds the tolerance range, it is determined that the dimension is unqualified. Integrating the length measurement function and the angle detection function into one body realizes the synchronous detection of multiple parameters. After the operator finishes clamping the workpiece at one workstation, key quality data such as the angle fitting situation, flatness deviation, and the straight pipe lengths on both sides can be immediately obtained, without the need to transfer the workpiece between multiple workstations or use multiple measuring tools, greatly reducing the comprehensive detection time of a single product, improving the overall efficiency of quality control, and reducing the risk of bumping caused by workpiece handling.

[0029] This invention also discloses a method for using a heat-resistant and wear-resistant bending and straight pipe angle detection device, comprising the following steps: S1: According to the pipe diameter specifications of the straight and bent pipe body 4 to be inspected, manually rotate the first screw 601 and the second screw 701 to drive the first sleeve 602 and the second sleeve 702 to move respectively. The first sleeve 602 adjusts the center height position of the adjustable elastic plate 302 through the sleeve 603 and the first connecting ball 604. The second sleeve 702 slides in the slide groove 3021 through the swing rod 703 and the slider 704, and together adjusts the distance and curvature of the adjustable elastic plate 302 relative to the lower arc plate 301, thereby forming a detection slot suitable for the current pipe diameter. S2: Then pull the moving plate 501 outward to overcome the elastic force of the elastic telescopic rod 5 and move it away from the detection seat 2. On the one hand, it drives the push plate 503 away from the track frame 3. On the other hand, the connecting plate 5023 pulls the arc plate 301 to slide horizontally relative to the auxiliary support plate 1001, so that a discharge port is formed between the end of the auxiliary support plate 1001 and the detection seat 2. S3: Then place the straight pipe body 4 to be tested into the channel formed by the auxiliary support plate 1001 and the limiting support plate 3022 on the adjustable elastic plate 302; A preliminary screening is conducted here: if the tube angle deviation is large or the shape is not up to standard, it will not be able to be successfully placed into this channel and can be directly judged as a defective product. S4: Then release the movable plate 501. Under the elastic force of the elastic telescopic rod 5, the movable plate 501 is reset and pushes the movable rod 502 forward. The movable rod 502 pushes the arc plate 301 to reset through the connecting plate 5023 and slides back to the bottom of the adjustable elastic plate 302 to provide bottom support for the bent pipe body 4. At the same time, the push plate 503, pushed by the moving rod 502, pushes the bent pipe body 4 forward along the channel formed by the auxiliary support plate 1001 and the limiting support plate 3022 until the bent pipe body 4 and the detection seat 2 are in close contact. S5: Multi-dimensional inspection can be performed after the straight pipe body 4 comes into contact with the detection seat 2. Straight pipe length inspection: Observe whether the ends of the straight pipe sections at both ends of the straight pipe body 4 are within the qualified range of the measuring scale lines on both sides of the measuring plate 13 of the inspection seat 2; Side flatness detection: The composite structure consisting of the center plate 5031 of the push plate 503 and the two rotatable side plates 5032 can adaptively fit the side of the bent pipe. If the side of the bent pipe is on the same plane, the two side plates 5032 will not deflect. Through the linkage mechanism consisting of the hinge rod 901, the movable rod 9 and the compression spring 902, the standard arrow 802 on the fixed pipe 8 points to the zero mark of the displacement scale line on the movable rod 9. At this time, the compression spring 902 is in a compressed state. If the side of the bent pipe body 4 is not flat, the side plate 5032 will deflect. The movable rod 9 will be moved by pushing / pulling the hinge rod 901, so that the standard arrow 802 points to a non-zero mark. The value is the flatness deviation. S6: Based on the detection results of step S5, the operator controls the rotating shaft 12 to rotate and adjusts the tilt direction of the flip plate 121. When performing the next inspection, step S2 is repeated. At this time, the arc plate 301 moves backward, and the bent and straight pipe body 4 that has been inspected loses its bottom support. Under the action of gravity, it automatically falls through the material drop channel and slides into the corresponding guide plate 122 along the flip plate 121 with the set direction, realizing automatic material feeding and automatic sorting.
