Description

Technical Field

[0001] This utility model relates to the technical field of pipe processing equipment, specifically a positioning mechanism for drilling PVC pipes. Background Technology

[0002] PVC pipes are widely used in construction, municipal engineering, agricultural irrigation and other fields. During the installation process, it is often necessary to drill installation holes, connection holes or wire passage holes on the pipes. Therefore, drilling equipment is usually required to drill PVC pipes. In order to improve the drilling accuracy and prevent the PVC pipes from deflecting during drilling, a positioning mechanism is needed to limit the PVC pipes. In the prior art, patent CN219968597U discloses a positioning device for PVC pipe processing, including a base, a controller fixedly connected to the top of the base, a sliding groove opened inside the base, a motor fixedly installed on the outside of the base, a lead screw fixedly connected to the output end of the motor, a limit cover fixedly connected to the outside of the lead screw, a bolt threadedly connected to the outside of the lead screw, a connecting rod fixedly connected to the top of the bolt, a transmission plate fixedly connected to the top of the connecting rod, a first stabilizing block fixedly connected to the top of the transmission plate, and a second stabilizing block fixedly connected to the top of the base; The positioning device for PVC pipe processing has the following disadvantages: the positioning cover moves by applying elastic force through a spring to clamp the PVC pipe, which makes the clamping of the PVC pipe unstable. During the drilling process, the PVC pipe is prone to deflection. At the same time, the PVC pipe is sleeved inside the clamping ring, which requires the drilling equipment to avoid the clamping ring when it approaches the PVC pipe, affecting the subsequent drilling efficiency. Therefore, we propose a positioning mechanism for drilling PVC pipes. Utility Model Content

[0003] The technical problem this invention aims to solve is to overcome existing defects and provide a positioning mechanism for drilling PVC pipes. Through the positioning component, multiple staggered clamping plates move synchronously, thereby applying pressure to multiple points on the inner wall of the PVC pipe from the inside, thus clamping the PVC pipe and achieving a better fixing effect. At the same time, the positioning component is located inside the PVC pipe, allowing the processing equipment to approach the outer surface of the PVC pipe without obstruction, avoiding any impact on the drilling process and ensuring drilling efficiency. This effectively solves the problems in the background art.

[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 1-4 This embodiment provides a technical solution: a positioning mechanism for drilling PVC pipes, a workbench 1, a mounting base 2 fixedly connected to the left side of the upper surface of the workbench 1, a rotating cylinder 3 rotatably connected inside the mounting base 2, a microcontroller 12 set outside the workbench 1, the input end of the microcontroller 12 being electrically connected to an external power supply, and also includes a positioning component 4. Positioning component 4 includes a slide cylinder 41, a baffle 42, a scale line 45, a sliding seat 46, a clamping plate 47, and slide rods 48. The slide cylinder 41 is slidably connected to the outer surface of the rotating cylinder 3. The baffle 42 is fixedly connected to the left side of the outer surface of the slide cylinder 41, and the clamping plates 47 are rotatably connected to the right side of the baffle 42. The sliding seat 46 is slidably connected to the right side of the outer surface of the slide cylinder 41, and the clamping plates 47 are also rotatably connected to the left side of the sliding seat 46. A fixing pin is rotatably connected between adjacent clamping plates 47 on both the left and right sides. The slide rods 48 are fixedly connected to the right side of the slide cylinder 41, and the fixed cylinders are fixedly connected to the left side of the sliding seat 46. All slide rods 48 are slidably connected to... Within the horizontally adjacent fixed cylinders, the upper surface of the worktable 1 is provided with evenly distributed scale lines 45. The positioning assembly 4 also includes an electric push rod 49, which is fixedly connected to the right side of the outer surface of the slide cylinder 41. A pressure sensor 13 is fixedly connected to the left end of the telescopic end of the electric push rod 49. The left end of the detection end of the pressure sensor 13 is fixedly connected to the right surface of the sliding seat 46. The input end of the electric push rod 49 is electrically connected to the output end of the microcontroller 12. During the movement of the telescopic end of the electric push rod 49, the slide rod 48 maintains a sliding connection with the fixed cylinder. The radial force is borne by the sliding support between the slide rod 48 and the fixed cylinder. Therefore, the electric push rod 49 experiences very little force in the radial direction, ensuring that the electric push rod 49 is in good working order. The moving push rod 49 is only subjected to force in the axial direction to avoid damage due to excessive radial force. The pressure sensor 13 is bidirectionally electrically connected to the microcontroller 12. The PVC pipe is fitted over the outside of the rotating drum 3, so that the left end of the PVC pipe is in contact with the right surface of the baffle 42. At this time, the microcontroller 12 is operated to start the electric push rod 49. The telescopic end of the electric push rod 49 extends, causing the pressure sensor 13 to move to the left, which in turn causes the sliding seat 46 to move to the left, causing the fixed cylinder and the right clamping plate 47 to move to the left. Since the adjacent clamping plates 47 on the left and right sides are rotatably connected by a fixing pin, the right clamping plate 47 moves to the left, causing the left clamping plate 47 to move as it moves to the left. The end away from the slide cylinder 41 moves away from the rotating cylinder 3, so that the end of the clamping plate 47 away from the slide cylinder 41 squeezes the inner wall of the PVC pipe. When the end of the clamping plate 47 away from the slide cylinder 41 squeezes the inner wall of the PVC pipe, the sliding seat 46 can no longer move to the left. At this time, the pressure on the detection end of the pressure sensor 13 increases, and the resistance inside the detection end of the pressure sensor 13 changes according to the pressure change. Thus, the pressure sensor 13 calculates the pressure value borne by the detection end and converts the pressure value data into an electrical signal and sends it to the microcontroller 12. When the pressure value reaches a certain level, the microcontroller 12 controls the extension end of the electric push rod 49 to stop moving. At this time, the PVC pipe is completely clamped. The positioning component 4 also includes an indicator plate 43 and a slot 44. The indicator plate 43 is rotatably connected to the outer surface of the baffle 42. The upper surface of the workbench 1 is provided with a slot 44. The lower end of the indicator plate 43 is slidably connected to the slot 44. The indicator plate 43 moves inside the slot 44. The distance the PVC pipe moves is indicated by the longitudinal position of the scale line 45 of the indicator plate 43. The rotating drum 3 is internally connected to a screw 7, and a slider 6 is threadedly connected to the outer surface of the screw 7. A groove 5 is provided on the upper side of the outer surface of the rotating drum 3. The upper end of the slider 6 is slidably connected in the groove 5. The upper surface of the slider 6 is fixedly connected to the inner surface of the slide drum 41. Corrugated pipes are fixedly connected between the left and right surfaces of the slider 6 and the inner wall of the rotating drum 3. The corrugated pipes are all sleeved on the outer surface of the screw 7 to protect the screw 7 and prevent external dust from sticking to the outer surface of the screw 7 and affecting the transmission of the screw 7. A motor 8 is fixedly connected to the left surface of the rotating drum 3. The right end of the output shaft of the motor 8 is fixedly connected to the left end of the screw 7. The input end of the motor 8 is electrically connected to the output end of the microcontroller 12. When the microcontroller 12 is operated, the motor 8 is started. The output shaft of the motor 8 rotates, which drives the screw 7 to rotate, causing the slider 6 to move, which in turn drives the slide drum 41 to move, which in turn moves the baffle 42, which in turn moves the clamping plate 47, thereby driving the PVC pipe to move laterally. A worm gear 10 is fixedly connected to the left side of the outer surface of the rotating drum 3. A worm 11 is rotatably connected inside the mounting base 2. The worm 11 meshes with the worm gear 10. Both the worm 11 and the worm gear 10 are located inside the mounting base 2, thus protecting the worm 11 and the worm gear 10 and preventing external dust from adhering to their surfaces and affecting the transmission. A second motor 9 is fixedly connected to the front surface of the mounting base 2. The rear end of the output shaft of the second motor 9 is fixedly connected to the front end of the worm 11. The input end of the second motor 9 is electrically connected to the output end of the microcontroller 12. When the microcontroller 12 is operated, the second motor 9 is started. The output shaft of the second motor 9 rotates, causing the worm 11 to rotate, which in turn causes the worm gear 10 to rotate, which in turn causes the rotating drum 3 to rotate. This causes the sliding cylinder 41 to rotate around the central axis of the rotating drum 3, which in turn causes the PVC pipe to rotate around the central axis of the rotating drum 3. This allows the angle of the PVC pipe to be adjusted, and the worm gear 10 can rotate more than 180° in both directions.

[0017] The working principle of the PVC pipe drilling positioning mechanism provided by this utility model is as follows: When using this PVC pipe drilling positioning mechanism to position the PVC pipe, the PVC pipe is sleeved on the outside of the rotating cylinder 3, so that the left end of the PVC pipe is in contact with the right surface of the baffle 42. At this time, the microcontroller 12 is operated to start the electric push rod 49. The telescopic end of the electric push rod 49 extends, driving the pressure sensor 13 to move to the left, causing the sliding seat 46 to move to the left, driving the fixed cylinder and the clamping plate 47 on the right side to move to the left. Since the adjacent left and right sides... A fixing pin is rotatably connected between the clamping plates 47. Therefore, as the right clamping plate 47 moves to the left, it drives the left clamping plate 47 to move, causing the ends of the clamping plates 47 away from the slide cylinder 41 to move away from the rotating cylinder 3. This causes the ends of the clamping plates 47 away from the slide cylinder 41 to press against the inner wall of the PVC pipe. When the ends of the clamping plates 47 away from the slide cylinder 41 press against the inner wall of the PVC pipe, the sliding seat 46 can no longer move to the left. At this time, the pressure on the detection end of the pressure sensor 13 increases, and the resistance inside the detection end of the pressure sensor 13 increases. The pressure sensor 13 calculates the pressure value at the detection end based on pressure changes, converts the pressure data into an electrical signal, and sends it to the microcontroller 12. When the pressure value reaches a certain level, the microcontroller 12 controls the extension end of the electric push rod 49 to stop moving, at which point the PVC pipe is fully clamped. Operating the microcontroller 12 starts motor 8, whose output shaft rotates, driving the screw 7 to rotate, causing the slider 6 to move, which in turn moves the slide cylinder 41, causing the baffle 42 to move, which in turn moves the clamping plate 47, thereby moving the PVC pipe... The horizontal movement simultaneously moves the indicator plate 43 within the slot 44. The distance the PVC pipe has moved is indicated by the longitudinal position of the scale line 45 on the indicator plate 43. The microcontroller 12 is operated to start the second motor 9. The output shaft of the second motor 9 rotates, causing the worm gear 11 to rotate, which in turn causes the worm wheel 10 to rotate, which in turn causes the rotating drum 3 to rotate. This causes the sliding cylinder 41 to rotate around the central axis of the rotating drum 3, thereby causing the PVC pipe to rotate around the central axis of the rotating drum 3. This allows the angle of the PVC pipe to be adjusted, and the worm wheel 10 can rotate more than 180° in both directions.

[0018] It is worth noting that, in the above embodiments, motor 8 can be YE2-80M1-2-B5, motor 9 can be 5IK120A1-AF, microcontroller 12 can be STM32F103C8T6, and pressure sensor 13 can be SGMH-102-50KG-10T. The microcontroller 12 controls the operation of motor 8, motor 9 and pressure sensor 13 using methods commonly used in the prior art.
