Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, specifically a pipe length cutting machine. Background Technology

[0002] Pipe fittings are components in a piping system used for connecting, controlling, changing direction, or adjusting pipe diameter. They are widely used in industries, construction, and energy. Pipe fittings are generally quite long after processing. In order to achieve a precise match between the pipe fittings and the piping system in terms of size, connection, and function, a pipe cutting machine is needed to cut the pipe fittings to the appropriate length. When using existing cutting machines, workers typically use fixing tools to secure the pipe fittings in the appropriate position, then measure the pipe fittings to the required length, and finally cut the pipe fittings using rotating cutting blades. Existing cutting machines have the following problems: the appropriate length needs to be measured manually before cutting, which is not convenient for cutting pipes in large batches, increases the workload of workers, and reduces the efficiency of cutting work during pipe processing. To address this, we propose a pipe length cutting machine. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a pipe length cutting machine. Before cutting the pipe, the required length of the pipe to be cut is set by the length-fixing mechanism. When the pipe is transported to the appropriate position, the pipe is automatically fixed and cut. The workload of the workers is reduced and the efficiency of pipe cutting is improved, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a pipe fitting length cutting machine, which includes a processing table before pipe fitting cutting, an adjustable cutting tool on the upper surface of the processing table, and a length fixing mechanism. The length-fixing mechanism includes a clearance groove, a bracket, a length-fixing plate, a pressure sensor, a pressure plate, a distance sensor, and a fixing component. Clearance grooves are provided on both the front and rear sides of the processing table. A bracket is slidably connected between the two clearance grooves. A length-fixing plate is provided on the upper surface of the bracket. A pressure sensor and a pressure plate are located in the mounting groove on the left side of the length-fixing plate. The pressure sensor is fixedly connected to the right wall of the mounting groove, and its detection end is fixedly connected to the right side of the pressure plate. A distance sensor is provided on the front side of the upper surface of the processing table, and a fixing component is provided on the left side of the processing table. By setting the required length of the pipe to be cut using the length-fixing mechanism, the pipe is automatically fixed and cut after it is transported to the appropriate position. This reduces the workload of the operator and improves the efficiency of pipe cutting.

[0005] Furthermore, it also includes a microcontroller, which is located on the front side of the processing table. The input terminal of the microcontroller is electrically connected to an external power supply, and the output terminals of the pressure sensor and the distance sensor are electrically connected to the input terminal of the microcontroller, respectively, to facilitate the normal operation of the equipment.

[0006] Furthermore, the length-fixing mechanism also includes a lead screw and a limiting rod. The lead screw is rotatably connected inside the clearance groove on the left side, and the outer surface of the lead screw is threadedly connected to the threaded hole on the left side of the bracket. The limiting rod is provided inside the clearance groove on the right side, and the outer surface of the limiting rod is slidably connected to the sliding hole on the right side of the bracket, which facilitates the movement of the length-fixing plate.

[0007] Furthermore, the fixing assembly includes a slide groove, a two-way lead screw, a slider, a clamping block, and a rubber pad. The slide groove on the left side of the upper surface of the processing table is rotatably connected to the two-way lead screw. The outer surface of the two-way lead screw is threaded with sliders on both the front and rear sides. The sliders are slidably connected to the inside of the slide groove. The upper surface of the sliders is provided with clamping blocks. The side of the clamping blocks near the center of the processing table is provided with rubber pads to facilitate fixing the pipe.

[0008] Furthermore, the processing table is equipped with motor one and motor two. The left end of the output shaft of motor one is fixedly connected to the right end of the lead screw, and the rear end of the output shaft of motor two is fixedly connected to the front end of the bidirectional lead screw. The input ends of motor one and motor two are respectively electrically connected to the output end of the microcontroller to provide driving force.

[0009] Furthermore, an electric push rod is provided in the mounting hole of the support seat on the rear side of the upper surface of the processing table. Positioning rods are provided on both the left and right sides inside the support seat. A support plate is slidably connected between the two positioning rods. The lower end of the telescopic shaft of the electric push rod is fixedly connected to the upper surface of the support plate. The input end of the electric push rod is electrically connected to the output end of the microcontroller, which facilitates the control of the cutting tool's up and down movement.

[0010] Furthermore, a cutting tool is rotatably connected to the slot on the front side of the support plate via a rotating shaft. A motor is provided on the right side of the support plate. The left end of the output shaft of the motor is fixedly connected to the right end of the rotating shaft. The input end of the motor is electrically connected to the output end of the microcontroller, which facilitates the control of the cutting tool rotation.

The rear end of the output shaft of motor four is fixedly connected to the front end of the rotating rod inside the lower part of the fixed seat on the left. The input end of motor four is electrically connected to the output end of the microcontroller, which facilitates the transportation of pipe fittings.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This pipe fitting length cutting machine has the following advantages: Before pipe cutting, the screw rotates and drives the fixed-length plate to move via the bracket. The distance between the cutting tool and the fixed-length plate is measured by the distance sensor, which determines the length of the pipe to be cut. During pipe cutting, the pipe moves to the right until its right end contacts the left side of the pressure plate. The pipe is pressed by the pressure plate, which then presses the probe end of the pressure sensor. The pressure sensor transmits the pressed signal to the microcontroller, causing the motor to run. The bidirectional screw rotates and drives the clamping blocks to move in opposite directions via the slider. The pipe is clamped and fixed by the rubber pad. The required pipe length can be preset. When the pipe is transported to the appropriate position, it is automatically fixed and cut. This reduces the workload of the workers and improves the efficiency of pipe cutting.

[0015] 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.

[0016] Please see Figure 1-5This embodiment provides a technical solution: a pipe fitting fixed-length cutting machine, including a processing table 1, an adjustable cutting tool 9 on the upper surface of the processing table 1, a fixed-length mechanism 3, and a microcontroller 2. The microcontroller 2 is located on the front side of the processing table 1, and its input end is electrically connected to an external power source. An electric push rod 6 is provided in the mounting hole of the support seat on the rear side of the upper surface of the processing table 1. Positioning rods 7 are provided on both the left and right sides inside the support seat. A support plate 8 is slidably connected between the two positioning rods 7. The lower end of the telescopic shaft of the electric push rod 6 is fixedly connected to the upper surface of the support plate 8. The input end of rod 6 is electrically connected to the output end of microcontroller 2. A cutting tool 9 is rotatably connected to the slot on the front side of support plate 8 via a rotating shaft. A motor 10 is located on the right side of support plate 8. The left end of the output shaft of motor 10 is fixedly connected to the right end of the rotating shaft. The input end of motor 10 is electrically connected to the output end of microcontroller 2. Fixed seats 11 are located on both the left and right sides of the upper surface of processing table 1. A fixed frame 15 is slidably connected to the upper side of each fixed seat 11. Support wheels 13 are rotatably connected to the interiors of both fixed seats 11 and fixed frames 15 via rotating rods 12. (The fixed seats 11 and fixed frames 15...) The mounting bracket 15 is fixed by bolts, which are threaded onto the front of the mounting base 11. The mounting bracket 15 is fixed by tightening the bolts. To adjust the distance between two vertically adjacent support wheels 13, loosen the bolts and pull the mounting bracket 15. A motor 14 is mounted on the upper surface of the processing table 1. The rear end of the output shaft of motor 14 is fixedly connected to the front end of the rotating rod 12 located inside the lower part of the mounting base 11 on the left. The input end of motor 14 is electrically connected to the output end of the microcontroller 2. The fitting is passed between two vertically adjacent support wheels 13. The microcontroller 2 is then activated to turn on motor 14. 14. The rotating rod 12 drives one of the support wheels 13 to rotate, and the friction causes the pipe to move from left to right. At the same time, the motor 3 10 drives the cutting tool 9 to rotate through the rotating shaft. The telescopic shaft of the electric push rod 6 drives the rotating cutting tool 9 to move downward along the positioning rod 7 to cut the pipe through the support plate 8. After cutting, the pipe falls into the material outlet on the right side of the upper surface of the processing table 1. At this time, the pressure sensor 34 does not detect pressure. The microcontroller 2 controls the motor 2 5 to reverse and release the fixation of the pipe. The motor 4 14 rotates to continue to transport the pipe and cut the pipe. The length-fixing mechanism 3 includes a clearance groove 31, a bracket 32, a length-fixing plate 33, a pressure sensor 34, a pressure plate 35, a distance sensor 36, and a fixing assembly 39. Clearance grooves 31 are provided on both the front and rear sides of the processing table 1. A bracket 32 ​​is slidably connected between the two clearance grooves 31. The upper surface of the bracket 32 ​​is provided with a length-fixing plate 33. A pressure sensor 34 and a pressure plate 35 are located in the mounting groove on the left side of the length-fixing plate 33. (The pressure sensor 34 is based on the resistance strain effect, sensing pressure through an elastic element. The deformation of the strain gauge causes a change in resistance, which is converted into a voltage signal via a bridge circuit and then transmitted to the microcontroller 2.) The pressure sensor 34 is fixedly connected to the right wall of the mounting groove. The detection end of the pressure sensor 34 is fixedly connected to the right side of the pressure plate 35. A distance sensor 36 is installed on the front side of the upper surface of the workbench 1. (When working, the distance sensor 36 emits a short laser pulse. Based on the time it takes for the laser pulse to travel from emission to reflection from the object being measured, combined with the speed of laser propagation in air, the distance between the distance sensor 36 and the object being measured is calculated, and then the data is transmitted to the microcontroller 2. The right side of the distance sensor 36 and the right side of the cutting tool 9 are located in the same plane. The distance measured by the distance sensor 36 is the distance between the cutting tool 9 and the length-fixing plate 33, which is also the length of the cut pipe.) A fixing component 39 is installed on the left side of the workbench 1. The output terminals of the pressure sensor 34 and the distance sensor 36 are electrically connected to the input terminals of the microcontroller 2, respectively. The length-fixing mechanism 3 also includes a wire. The support includes rod 37 and limiting rod 38. A lead screw 37 is rotatably connected inside the clearance groove 31 on the left side. The outer surface of the lead screw 37 is threadedly connected to a threaded hole on the left side of the bracket 32. A limiting rod 38 is provided inside the clearance groove 31 on the right side. The outer surface of the limiting rod 38 is slidably connected to a sliding hole on the right side of the bracket 32. The fixing assembly 39 includes a slide groove 391, a bidirectional lead screw 392, a slider 393, a clamping block 394, and a rubber pad 395. A bidirectional lead screw 392 is rotatably connected inside the slide groove 391 on the left side of the upper surface of the processing table 1. Slider blocks 393 are threadedly connected to both the front and rear sides of the outer surface of the bidirectional lead screw 392. (Both the exposed portions of the outer surfaces of the lead screw 37 and the bidirectional lead screw 392 are provided with bellows, which are fixedly connected to the inner wall of the clearance groove 31.) The corrugated pipe extends or contracts when the bracket 32 ​​and slider 393 move, along with the inner wall of the slide groove 391, the side of the slider 393, and between the two sliders 393. This ensures the sealing and lubrication of the lead screw 37 and the bidirectional lead screw 392. The sliders 393 are slidably connected inside the slide groove 391. Each slider 393 has a clamping block 394 on its upper surface. Each clamping block 394 has a rubber pad 395 on its side near the center of the processing table 1. The processing table 1 contains a motor 4 and a motor 5. The left end of the output shaft of motor 4 is fixedly connected to the right end of the lead screw 37. The rear end of the output shaft of motor 5 is fixedly connected to the front end of the bidirectional lead screw 392. The input ends of motor 4 and motor 5 are electrically connected to the output ends of the microcontroller 2.Controlled by the microcontroller 2, the motor 4 drives the lead screw 37 to rotate. The rotation of the lead screw 37 causes the bracket 32 ​​to move along the clearance groove 31 under the restriction of the limit rod 38. The bracket 32 ​​drives the fixed length plate 33 to move. During the movement of the fixed length plate 33, the distance sensor 36 emits a short laser pulse towards the left side of the fixed length plate 33. The laser pulse is reflected by the fixed length plate 33 and received by the distance sensor 36. The distance sensor 36 transmits the data to the microcontroller 2, so the operator can know the distance between the cutting tool 9 and the fixed length plate 33, that is, the distance to be cut into the pipe fitting. When the length-fixing plate 33 moves to the appropriate position, motor 4 stops working until the right end of the pipe contacts the left side of the pressure plate 35. The pipe is pressed by the pressure plate 35 against the detection end of the pressure sensor 34. The pressure sensor 34 transmits the pressed signal to the microcontroller 2. The microcontroller 2 controls motor 5 to work and motor 14 to stop working. The bidirectional lead screw 392 rotates, driving the threaded sliders 393 on both sides to move towards each other along the slide groove 391. The sliders 393 drive the clamping blocks 394 to move towards each other, clamping and fixing the pipe through the rubber pad 395.

[0017] The working principle of the pipe length cutting machine provided by this utility model is as follows: Under the control of the microcontroller 2, motor 4 drives the lead screw 37 to rotate. The rotation of the lead screw 37 causes the support 32 to move along the clearance groove 31 under the restriction of the limiting rod 38. The support 32 drives the length-fixing plate 33 to move. During the movement of the length-fixing plate 33, the distance sensor 36 emits a short laser pulse towards the left side of the length-fixing plate 33. The laser pulse is reflected by the length-fixing plate 33 and received by the distance sensor 36. The distance sensor 36 transmits the data to the microcontroller 2, allowing the operator to know the distance between the cutting tool 9 and the length-fixing plate 33, i.e., the length of the pipe to be cut. When the length-fixing plate 33 moves to the appropriate position, motor 4 stops working. The pipe is then passed between two vertically adjacent support wheels 13. The microcontroller 2 then activates motor 4. Motor 4 drives one of the support wheels 13 to rotate via the rotating rod 12, causing the pipe to move from left to right through friction. The tube is pressed until its right end contacts the left side of the pressure plate 35. The pressure plate 35 presses the probe end of the pressure sensor 34. The pressure sensor 34 transmits the pressed signal to the microcontroller 2. The microcontroller 2 controls the operation of motor 2 5 and the shutdown of motor 4 14. The bidirectional lead screw 392 rotates, driving the threaded sliders 393 on both sides to move towards each other along the slide groove 391. The sliders 393 drive the clamping blocks 394 to move towards each other and clamp the tube through the rubber pad 395. At the same time, motor 3 10 runs and drives the cutting tool 9 to rotate through the shaft. The telescopic shaft of the electric push rod 6 drives the rotating cutting tool 9 to move downward along the positioning rod 7 through the support plate 8 to cut the tube. After cutting, the tube falls into the material outlet on the right side of the upper surface of the processing table 1. At this time, the pressure sensor 34 does not detect pressure. The microcontroller 2 controls motor 2 5 to reverse and release the fixation of the tube. Motor 4 14 rotates to continue transporting the tube and cutting it.

[0018] It is worth noting that the microcontroller 2 disclosed in the above embodiments can be an AVR series, the pressure sensor 34 can be an HBM series strain gauge pressure sensor, the distance sensor 36 can be an LTF laser sensor, the motor 4 and motor 5 can be YP-100 series, and the motor 10 and motor 14 can be A6 series servo motors. The microcontroller 2 controls the operation of the pressure sensor 34, distance sensor 36, motor 4, motor 5, electric actuator 6, motor 10 and motor 14 using methods commonly used in the prior art.
