Description

Technical Field

[0001] This utility model relates to the field of alignment device technology, specifically a high-pressure nozzle self-centering alignment device. Background Technology

[0002] In the production and manufacturing of machining cleaning machines, the positioning calibration of the high-pressure jet pipe is a key step to ensure the cleaning effect and equipment stability.

[0003] Traditional high-pressure spray nozzle positioning calibration in machining and cleaning machines relies heavily on manual measurement and experience, often using tools such as calipers and dial indicators for positioning and calibration. This method not only requires operators to have extensive experience and high skill levels, but the operation process is also cumbersome and easily affected by human factors, leading to unstable calibration accuracy. In addition, during installation and disassembly, the lack of convenient auxiliary devices requires a lot of time to adjust and fix the components, resulting in extremely low overall efficiency. Therefore, it is necessary to design a high-pressure spray nozzle self-centering and alignment device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a high-pressure nozzle self-centering and alignment device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-pressure nozzle self-centering alignment device, comprising a sleeve, wherein self-centering clamping structures are provided at both ends of the sleeve, and the self-centering clamping structures are used for high-pressure nozzle alignment;

[0006] The sleeve is provided with knobs at both ends, and the self-centering clamping structure can be tightened or loosened by rotating the knobs;

[0007] One set of the knobs is detachably connected to a set of laser generators, which are used to assist in the calibration of the high-pressure nozzle position.

[0008] Preferably, the self-centering clamping structure includes nylon flaps, linkage rods, and arc-shaped grooves. Multiple nylon flaps are evenly distributed at both ends of the sleeve along the circumferential direction. Two sets of linkage rods are non-coaxially arranged on both sides of the nylon flaps. One set of linkage rods is movably connected to the sleeve, and the other set of linkage rods can slide along the arc-shaped groove opened in the inner cavity of the knob.

[0009] Preferably, by rotating the knob, the arc groove guides a set of the linkage rods that are adapted to it, causing the nylon flaps to open and close synchronously around the central axis of the sleeve, thereby achieving the clamping or loosening of the high-pressure nozzle by the self-centering clamping structure.

[0010] Preferably, multiple sets of damping blocks are equidistantly arranged on the inner circumference of one end of the knob, and the sleeve end is provided with a slot and a groove. The damping blocks can pass through the slot and enter the groove to rotate. When the knob is rotated, the damping blocks press against the groove wall of the groove to generate damping force, thereby achieving anti-slip locking. The knob can be disassembled by rotating it in the opposite direction, which takes into account both locking stability and easy disassembly and assembly.

[0011] Preferably, one set of the knobs is plugged into the laser generator and fixed by a locking bolt. The locking bolt passes through the preset through hole of the knob and engages with the threaded hole of the laser generator, thereby firmly locking the laser generator on the corresponding knob and ensuring a reliable connection.

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

[0013] This utility model's self-centering clamping structure can automatically position the high-pressure nozzle at the center of the sleeve, avoiding errors caused by differences in experience, skills, and human operation in manual measurement. The precise reference line provided by the laser generator further improves the accuracy of position calibration and ensures the stability of calibration precision. No operator with rich experience and high skill level is required. The alignment and calibration of the high-pressure nozzle can be completed by simply operating the self-centering clamping structure and the laser generator through a knob, simplifying the operation process. The self-centering clamping structure can quickly achieve the installation and fixation of the high-pressure nozzle, which greatly reduces the time for component adjustment and fixation compared to the traditional installation method without auxiliary devices.

[0014] The nylon material of this invention has a certain degree of elasticity and friction, which can effectively prevent the nozzle from sliding relative to each other during clamping, thus enhancing the locking effect. When the nylon flaps are attached to the high-pressure nozzle, their elasticity can adapt to the slight unevenness of the nozzle surface, fill the gaps, increase the contact area, and further enhance the locking effect. In addition, the soft texture of the nylon flaps will not damage the surface of the high-pressure nozzle. While achieving reliable locking, it protects the integrity of the nozzle, laying a stable foundation for subsequent accurate position calibration.

[0015] This utility model's damping block, when rotating and pressing against the groove wall, generates damping force to prevent slippage and self-locking, much like adding an "anti-slip lock" to the knob. During the high-pressure nozzle alignment process, it effectively resists external interference forces, preventing accidental knob rotation and ensuring that the clamping force of the nylon flaps on the high-pressure nozzle remains stable, maintaining the nozzle's centering state. Reversing the knob opens the nylon flaps to unlock the high-pressure nozzle. Only when the damping block is rotated to match the slot can the knob be pulled out and removed, avoiding misoperation. The double locking ensures accurate nozzle positioning, prevents loosening, and improves calibration accuracy. The knob and laser generator are fixed by plugging and locking bolts, ensuring accurate laser calibration benchmarks and providing a guarantee for high-precision calibration of the high-pressure nozzle. It is also easy to assemble and disassemble. Attached Figure Description

[0024] 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.

[0025] Example 1

[0026] Please refer to Figure 1-7 As shown, this utility model provides a high-pressure nozzle self-centering alignment device, including a sleeve 1, with self-centering clamping structures at both ends of the sleeve 1, which are used for high-pressure nozzle alignment.

[0027] The sleeve 1 is equipped with knobs 2 at both ends, and the self-centering clamping structure can be tightened or loosened by rotating the knobs 2.

[0028] One set of knobs 2 is detachably connected to a set of laser generators 3, which are used to assist in the calibration of the high-pressure nozzle position.

[0029] The high-pressure nozzle is placed inside the sleeve 1. By rotating the knobs 2 at both ends of the sleeve 1, the self-centering clamping structure is driven to automatically clamp and position the high-pressure nozzle, ensuring that the nozzle is in the center position of the sleeve. Then, the laser generator 3, which is detachably connected to the knob 2, is installed and turned on. The laser beam emitted by the laser generator 3 serves as a reference line, assisting the operator in visually calibrating the position of the high-pressure nozzle in space and achieving precise positioning.

[0030] The self-centering clamping structure automatically positions the high-pressure nozzle at the center of the sleeve, avoiding errors caused by differences in experience, skills, and human operation in manual measurement. The precise reference line provided by the laser generator further improves the accuracy of position calibration and ensures the stability of calibration precision. No operator with extensive experience or high skill level is required. The alignment and calibration of the high-pressure nozzle can be completed by simply operating the self-centering clamping structure and the laser generator through a knob, simplifying the operation process. The self-centering clamping structure can quickly install and fix the high-pressure nozzle, significantly reducing the time for component adjustment and fixing compared to traditional installation methods that lack auxiliary devices.

[0031] Specifically, the self-centering clamping structure includes nylon flaps 4, linkage rods 5, and arc-shaped grooves 6. Multiple nylon flaps 4 are evenly distributed at both ends of the sleeve 1 along the circumferential direction. Two sets of linkage rods 5 are non-coaxially arranged on both sides of the nylon flaps 4. One set of linkage rods 5 is movably connected to the sleeve 1, and the other set of linkage rods 5 can slide along the arc-shaped grooves 6 opened in the inner cavity of the knob 2. By rotating the knob 2, the arc-shaped grooves 6 guide the set of linkage rods 5 that are adapted to them, so that the nylon flaps 4 open and close synchronously with the central axis of the sleeve 1 as the center, thereby realizing the clamping or loosening of the high-pressure nozzle by the self-centering clamping structure.

[0032] When the knob 2 is turned, the arc-shaped groove 6 inside the knob 2 guides a set of linkage rods 5 that are adapted to it, so that the nylon flaps 4 open and close synchronously with the central axis of the sleeve 1 as the center. This synchronous opening and closing design can ensure that multiple nylon flaps 4 apply pressure evenly to the high-pressure nozzle from multiple directions, tightly fit the nozzle surface, avoid loosening caused by uneven local force, and thus form a stable clamping and locking state.

[0033] Nylon material itself has a certain degree of elasticity and friction, which can effectively prevent the nozzle from sliding relative to each other during clamping, thus enhancing the locking effect. When the nylon flap 4 is attached to the high-pressure nozzle, its elasticity can adapt to the slight unevenness of the nozzle surface, fill the gaps, increase the contact area, and further enhance the locking effect. In addition, the soft texture of the nylon flap 4 will not damage the surface of the high-pressure nozzle. While achieving reliable locking, it protects the integrity of the nozzle, laying a stable foundation for subsequent accurate position calibration.

[0034] Among them, multiple sets of damping blocks 7 are equidistantly arranged on the inner circumference of one end of the knob 2. The sleeve 1 has a corresponding slot 8 and a sliding groove 9. The damping blocks 7 can pass through the slot 8 and enter the sliding groove 9 to rotate. When the knob 2 is rotated, the damping blocks 7 press against the groove wall of the sliding groove 9 to generate damping force, so as to achieve anti-slip locking. The knob 2 can be disassembled by rotating it in the opposite direction. It takes into account both the stability of locking and the convenience of disassembly and assembly. One set of knobs 2 is connected to the laser generator 3 by plug-in connection and is fixed by locking bolts 10. After the locking bolts 10 pass through the preset through hole of the knob 2, they are screwed into the threaded hole of the laser generator 3, thereby firmly locking the laser generator 3 on the corresponding knob 2 to ensure reliable connection.

[0035] Rotating knob 2 in the forward direction causes the inner arc groove 6 to drive the nylon flap 4 to close, achieving self-centering and locking of the high-pressure nozzle. At the same time, the damping block 7 rotates and presses against the groove wall of the slide groove 9, generating damping force to prevent slipping and self-locking, which is like adding an "anti-slip lock" to knob 2. During the high-pressure nozzle alignment process, it effectively resists external interference forces and prevents knob 2 from rotating accidentally, thereby ensuring that the clamping force of the nylon flap 4 on the high-pressure nozzle remains stable and maintaining the centering state of the nozzle. Rotating knob 2 in the reverse direction causes the nylon flap 4 to open and unlock the high-pressure nozzle. Only when the damping block 7 is rotated to match the slot 8 can knob 2 be pulled out and removed to avoid misoperation. The double locking ensures accurate nozzle positioning, prevents loosening, and improves calibration accuracy. Knob 2 and laser generator 3 are fixed by plugging and locking bolts 10 to ensure the accuracy of laser calibration benchmark, providing a guarantee for high-precision calibration of the high-pressure nozzle, and is easy to disassemble and assemble.

[0036] Working principle: For the installation of laser generator 3, it is connected to one of the sets of knobs 2 via a plug-in connection. Then, the locking bolt 10 is passed through the preset through hole of knob 2 and screwed into the threaded hole of laser generator 3 to securely fix laser generator 3 on knob 2. After installation, laser generator 3 is turned on. The laser beam emitted by it can be used as a calibration reference to assist the operator in accurately calibrating the position of high-pressure nozzle, thus completing the entire installation and calibration work. The high-pressure nozzle is placed in sleeve 1. Nylon lobes 4 are evenly distributed along the circumference at both ends of sleeve 1. Through the non- The coaxially arranged linkage rod 5 cooperates with the sleeve 1 and the knob 2. The knob 2 is installed at the end of the sleeve 1. The damping blocks 7, which are equidistantly arranged on the circumference of the inner cavity of one end of the knob 2, pass through the slot 8 at the end of the sleeve 1 and enter the slide groove 9. At this time, when the knob 2 is rotated, the arc-shaped groove 6 in the inner cavity of the knob 2 generates a guiding force on the linkage rod 5, so that the nylon flaps 4 close synchronously with the central axis of the sleeve 1 as the center, clamping the high-pressure nozzle and realizing self-centering installation. At the same time, as the knob 2 rotates, the damping blocks 7 gradually press against the groove wall of the slide groove 9, generating damping force to prevent the knob 2 from rotating accidentally and to ensure the stability of the self-centering structure.
