Description

Technical Field

[0001] This utility model relates to the field of seamless steel pipe processing, and in particular to a device for detecting the outer diameter of seamless steel pipes. Background Technology

[0002] Seamless steel pipes are made from a single piece of metal and have no seams on their surface. They are mainly used as oil and geological drilling pipes, cracking pipes for petrochemicals, boiler tubes, bearing tubes, and high-precision structural steel pipes for automobiles, tractors, and aviation. After production, seamless steel pipes must be tested to ensure that their inner and outer diameters meet the qualification requirements before they can be used.

[0003] Chinese patent CN221445045U discloses a device for detecting the outer diameter of a seamless steel pipe. The lasers emitted by the upper and lower laser lamps are tangent to the upper and lower end faces of the seamless steel pipe body, respectively. At this time, the lasers emitted by the upper and lower laser lamps illuminate a ruler. The value between the two sets of lasers is read through the ruler, and this value is the outer diameter of the seamless steel pipe body. The outer diameter of the seamless steel pipe body can be detected quickly, replacing the method of using vernier calipers. The detection method is simple and fast.

[0004] In the aforementioned patent literature, by moving the upper and lower laser lights, the lasers emitted by the upper and lower laser lights are controlled to be tangent to the upper and lower end faces of the seamless steel pipe body, respectively. However, during the adjustment process, it is impossible to guarantee that the laser is precisely tangent to the steel pipe, which will cause certain errors in the test results. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the inability to ensure precise tangency between the laser and the steel pipe during adjustment, which can lead to errors in the detection results. Therefore, this invention proposes a seamless steel pipe outer diameter detection device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A seamless steel pipe outer diameter detection device includes a base, a support seat fixedly installed on the base, a placement groove opened on the upper surface of the support seat, a U-shaped bracket fixedly installed on the base, and a pressure plate installed on the bracket through an elastic component.

[0008] A support block is fixedly installed on the base, and the upper surface of the support block is flush with the bottom of the placement groove. A support frame is fixedly installed on the side of the pressure plate, and a rectangular plate is fixedly installed at one end of the support frame. A distance sensor is fixedly installed at one end of the rectangular plate through a fixing seat. An installation groove is opened on the upper surface of the support block, and a receiver is fixedly installed in the installation groove. The receiver is located directly below the distance sensor.

[0009] Preferably, the bracket has a movable hole, and the elastic component includes a movable rod that is vertically slidably installed in the movable hole, a telescopic spring sleeved on the movable rod, and a pull rod fixedly installed on the upper end of the movable rod. The two ends of the telescopic spring are respectively fixedly connected to the bracket and the pressure plate.

[0010] Preferably, a protective pad is fixedly installed on the lower surface of the pressure plate, and the protective pad is made of rubber.

[0011] Preferably, a display is fixedly mounted on the upper surface of the base, and the display is electrically connected to the distance sensor.

[0012] Preferably, support plates are symmetrically fixedly installed on the base, and the support seat is installed between the two support plates. Each of the two support plates has a clamp plate installed on its opposite side by multiple spring rods.

[0013] Preferably, guide plates are fixedly installed at the upper ends of both clamps at an incline, and the two guide plates are arranged in an inverted V-shape.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. When inspecting the outer diameter of seamless steel pipe, the seamless steel pipe is clamped on the support base by the pressure plate. At the same time, the support block and the rectangular plate are tangent to the upper and lower end faces of the seamless steel pipe, respectively. At this time, the outer diameter of the seamless steel pipe can be measured directly by the distance sensor and the receiving part. The operation is simple and convenient, and the accuracy of the inspection structure is guaranteed.

[0016] 2. When the seamless steel pipe is clamped on the support base, the seamless steel pipe is positioned in the middle of the placement groove through the cooperation of the support plate, spring rod and clamping plate, ensuring that the lower end face of the seamless steel pipe is in contact with the upper surface of the support block, further reducing the detection error.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 A seamless steel pipe outer diameter detection device includes a base 1, a support 2 fixedly installed on the base 1, a placement groove opened on the upper surface of the support 2, a U-shaped bracket 3 fixedly installed on the base 1, and a pressure plate 4 installed on the bracket 3 through an elastic component. The placement groove is used to place the seamless steel pipe to be tested.

[0024] A support block 5 is fixedly installed on the base 1. The upper surface of the support block 5 is flush with the bottom of the placement groove. A support frame 6 is fixedly installed on the side of the pressure plate 4. A rectangular plate 7 is fixedly installed on one end of the support frame 6. A distance sensor 8 is fixedly installed on one end of the rectangular plate 7 through a fixing seat. An installation groove is opened on the upper surface of the support block 5. A receiver 9 is fixedly installed in the installation groove. The receiver 9 is located directly below the distance sensor 8. A display 13 is fixedly installed on the upper surface of the base 1. The display 13 is electrically connected to the distance sensor 8.

[0025] Both the distance sensor 8 and the receiver 9 are existing technologies. The distance sensor 8 can emit a laser, and the receiver 9 is used to receive the laser and measure the distance between the distance sensor 8 and the receiver 9. The distance between the distance sensor 8 and the receiver 9 is the same as the distance between the support block 5 and the rectangular plate 7.

[0026] When measuring the outer diameter of a seamless steel pipe, the seamless steel pipe is placed on the support base 2. Then, the pressure plate 4 is driven by the elastic component to contact the upper end face of the seamless steel pipe, clamping the seamless steel pipe on the support base 2. When the seamless steel pipe is placed in the placement groove, the lower end face of the seamless steel pipe is in contact with the upper surface of the support block 5. When the pressure plate 4 contacts the seamless steel pipe, the rectangular plate 7 is in contact with the upper end face of the seamless steel pipe. At this time, the distance between the rectangular plate 7 and the support block 5 is exactly the same as the outer diameter of the seamless steel pipe. Then, the outer diameter of the seamless steel pipe is measured by the distance sensor 8 and the receiver 9. The outer diameter of the seamless steel pipe can be directly read through the display 13. The operation is simple and convenient, ensuring the accuracy of the detection structure.

[0027] The bracket 3 has a movable hole. The elastic component includes a movable rod 10 that is vertically slidably installed in the movable hole, a telescopic spring 11 sleeved on the movable rod 10, and a pull rod 12 fixedly installed on the upper end of the movable rod 10. The two ends of the telescopic spring 11 are fixedly connected to the bracket 3 and the pressure plate 4, respectively. The pressure plate 4 is vertically slidably installed on the bracket 3 through the movable rod 10. Under the action of the elastic force of the telescopic spring 11, the pressure plate 4 tends to move vertically downward. When placing the seamless steel pipe, first pull the pull rod 12 to drive the movable rod 10 to move vertically upward, compressing the telescopic spring 11. Then, place the seamless steel pipe in the placement groove. At this time, release the pull rod 12. Under the action of the elastic force of the telescopic spring 11, the movable rod 10 drives the pressure plate 4 to contact the seamless steel pipe.

[0028] A protective pad made of rubber is fixedly installed on the lower surface of the pressure plate 4. When the pressure plate 4 comes into contact with the seamless steel pipe, the protective pad can protect the seamless steel pipe and prevent the surface of the seamless steel pipe from being worn.

[0029] Support plates 14 are symmetrically fixed on the base 1. Support seat 2 is installed between the two support plates 14. Each of the two support plates 14 has a clamping plate 16 installed on its opposite side by multiple spring rods 15. Guide plates 17 are fixedly installed at the upper end of each of the two clamping plates 16 at an inverted V-shape.

[0030] When placing the seamless steel pipe, place it between the two guide plates 17 and press it down. Under the action of the guide plates 17, the two clamping plates 16 can be moved away from each other, and the spring rod 15 is compressed until the seamless steel pipe moves between the two clamping plates 16. The lower end face of the seamless steel pipe contacts the bottom of the placement groove. The two clamping plates 16 ensure that the seamless steel pipe is clamped in the middle of the support base 2 and that the lower end face of the seamless steel pipe contacts the upper surface of the support block 5, further reducing the detection error.

[0031] In this invention, when measuring the outer diameter of a seamless steel pipe, the seamless steel pipe is placed on the support base 2, and then the pressure plate 4 is driven by the elastic component to contact the upper end face of the seamless steel pipe, clamping the seamless steel pipe on the support base 2. When the seamless steel pipe is placed in the placement groove, the lower end face of the seamless steel pipe is in contact with the upper surface of the support block 5. When the pressure plate 4 contacts the seamless steel pipe, the rectangular plate 7 is in contact with the upper end face of the seamless steel pipe. At this time, the distance between the rectangular plate 7 and the support block 5 is exactly the same as the outer diameter of the seamless steel pipe. Then, the outer diameter of the seamless steel pipe is measured by the distance sensor 8 and the receiver 9. The operation is simple and convenient, ensuring the accuracy of the detection structure.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
