Description

Technical Field

[0001] This utility model relates to the field of pipe inner diameter detection technology, specifically to a laser online detection device for the inner diameter of plastic pipes. Background Technology

[0002] Plastic pipes, with their advantages of light weight, corrosion resistance, and low cost, are widely used in many fields such as building water supply and drainage, municipal engineering, agricultural irrigation, and industrial fluid transportation. The inner diameter, as a key quality indicator of plastic pipes, directly affects the pipe's connection sealing performance, fluid transportation efficiency, and overall performance.

[0003] Currently, the industry widely relies on laser measuring instruments for internal diameter inspection. However, the existing inspection method has a fatal flaw: limited by the mechanical structure and control logic of the inspection mechanism, the laser inspection unit can only capture data at a fixed point inside the pipe. This single-point inspection method has significant drawbacks: it cannot cover different radial sections in the circumferential direction of the pipe, nor can it cover different sections in the axial direction. As a result, the collected data can only reflect the local state and cannot outline the overall dimensional distribution characteristics of the internal diameter. The resulting inspection results have a large deviation, which can not only mislead the adjustment of production parameters and cause batch products to fail to meet dimensional standards, but also may create safety hazards due to hidden dimensional defects, seriously restricting the improvement of production efficiency and product quality. Utility Model Content

[0004] The purpose of this invention is to provide an online laser detection device for the inner diameter of plastic pipes to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes an online laser detection device for the inner diameter of plastic pipes, including a base, a conveying pipe on the top of the base, a position adjustment mechanism on one side of the top of the base, and a fixing mechanism on the top of the base.

[0006] The position adjustment mechanism includes two side plates fixedly connected to one side of the top of the base. Two grooves are formed on one side of each side plate, and a first sliding rod is fixedly connected to the inner wall of each groove. A spring is fitted onto the outer wall of each first sliding rod, and a slider is slidably connected to the outer wall of each first sliding rod. A support frame is fixedly connected between each slider. A baffle is fixedly connected to one side of each of the two side plates, and a first connecting rod is rotatably connected between the two baffles. Cams are fixedly connected to both ends of the outer wall of the first connecting rod.

[0007] In one example, a first servo motor is fixedly connected to one side of one of the baffles, and one side of the first connecting rod is fixedly connected to the output end of the first servo motor.

[0008] In one example, a second connecting rod is rotatably connected to one side of the support frame, a laser detection head is fixedly connected to one end of the second connecting rod, a second servo motor is fixedly connected to the other side of the support frame, and one end of the second connecting rod is fixedly connected to the output end of the second servo motor.

[0009] In one example, the fixing mechanism includes two support rods fixedly connected to the top two sides of the base, wherein the bottom of the two support rods is rotatably connected to a lead screw, and the outer wall of the lead screw is threadedly connected to a fixing frame; the bottom of the other two support rods is fixedly connected to a second slide rod, and the other end of the fixing frame is slidably connected to the outer wall of the second slide rod.

[0010] In one example, two synchronous wheels are rotatably connected to one side of the bottom of the base. A third connecting rod is fixedly connected to the top of each of the two synchronous wheels, and the third connecting rod is fixedly connected to the bottom of the lead screw. A synchronous belt is fitted on the outer wall of each of the two synchronous wheels. A third servo motor is provided at the bottom of one of the synchronous wheels, and the drive shaft of one of the synchronous wheels is fixedly connected to the output end of the third servo motor.

[0011] In one example, a smart control panel is provided on one side of the base, and the surface of the smart control panel is provided with switches for a first servo motor, a second servo motor, and a third servo motor. The first servo motor, the second servo motor, and the third servo motor are electrically connected via an external power supply.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. A side plate is located on the top of the base. Two grooves are provided on one side of each side plate, and a first sliding rod is located inside each groove. A spring is provided outside the first sliding rod, and a slider is slidably mounted on the outer wall of each first sliding rod. A support frame is located between the two side plates, and the sliders are fixedly connected to the four corners of the support frame. A baffle is located on one side of each side plate, and a first connecting rod is located between the two baffles. A cam is located outside the first connecting rod. When the inner diameter of the plastic pipe is being measured, and when different depths of the inner diameter need to be measured, rotating the cam will cause the cam to move forward against the support frame. A laser detector is located on the other side of the support frame, and the laser detector will move inside the plastic pipe, thus enabling the measurement of different depths of the plastic pipe. This allows for the collection of more data during the measurement process, making the inner diameter measurement of the plastic pipe more accurate and improving the precision of the measurement process.

[0014] 2. A laser detection head is provided on one side of a second connecting rod located on one side of the support frame. The second connecting rod is rotatably connected to one side of the support frame, so that the laser detection head can be driven to rotate under the drive of the second servo motor, thereby enabling the detection and processing of different surfaces with the same center inside the plastic pipe.

[0015] 3. A support rod is installed at the top of the base, with a lead screw and a second slide rod at the bottom of the support rod. A fixing frame is installed between the lead screw and the second slide rod, with one end of the fixing frame threaded to the lead screw and the other end slidably connected to the second slide rod. A synchronous pulley is installed at the bottom of the base, and the two synchronous pulleys are driven by a synchronous belt, so that the lead screw at the top can rotate simultaneously. This controls the descent of the fixing frame at the top, thereby fixing the surface of the plastic pipe and preventing the plastic pipe from rotating during the testing process, which would lead to inaccurate test data.
