Description

Technical Field

[0001] This invention relates to the field of pipe processing equipment technology, specifically to a multi-angle universal adjustment gimbal locking mechanism for an infrared heater used in pipe processing. Background Technology

[0002] In the field of pipe processing, such as bending of plastic pipes, hot-melt connection, or curing of composite pipes, infrared heaters are often used to locally and precisely heat specific parts of the pipe. In order to make the heating effect uniform and adapt to the processing needs of different pipe diameters, different bending angles, or complex spatial positions, the irradiation angle and position of the infrared heater must be able to be flexibly and precisely adjusted. Therefore, a support mechanism, namely a "gimbal", is needed to support the heater and realize multi-dimensional (usually horizontal rotation and vertical pitch) adjustment. After adjustment, the mechanism must be able to firmly lock the heater in the required position to prevent displacement due to vibration or its own weight during processing, thus ensuring processing quality and operational safety. However, the existing technology has certain technical defects in the adjustment process. The existing adjustment gimbal may be manually adjusted and then fixed with a separate mechanical locking device (such as a tightening handle, pin, etc.). This step-by-step operation of "adjust first and then lock" is inefficient. Moreover, if the locking is forgotten or not locked properly after adjustment, the equipment may move unexpectedly during operation, which poses a safety risk. Second, when the motor of an existing electrically driven gimbal stops due to power failure, its transmission mechanism may move in the opposite direction or slip due to external force or the weight of the load (such as a heater). The existing technology lacks a locking mechanism that is automatically linked to the motor's start and stop status, and cannot achieve the safety protection function of "locking down when power is cut off". In view of this, the present invention proposes a multi-angle universal adjustment gimbal locking mechanism for an infrared heater processed from tubing. Summary of the Invention

[0003] This invention proposes a multi-angle universal adjustment gimbal locking mechanism for an infrared heater in tubular processing, which solves the problem of high safety risks caused by the inability to achieve self-locking in the prior art.

[0004] The technical solution of the present invention is as follows: A multi-angle universal adjustable gimbal locking mechanism for an infrared heater processed from tubing includes a base, a mounting box fixedly connected to the top of the base, a gimbal base fixedly connected to the top of the mounting box, an adjustment module provided on the gimbal base, the adjustment module including a hollow shaft penetrating the top wall of the gimbal base and rotatably connected to the gimbal base, a transverse rotating seat fixedly connected to the top of the hollow shaft, a longitudinal rotating seat rotatably connected to the inner side of the transverse rotating seat, a mounting plate for fixing to the infrared heater fixedly connected to one end of the longitudinal rotating seat, a first driving component for driving the hollow shaft to rotate provided on the inner side of the gimbal base, a locking component for locking the hollow shaft by cooperating with the start and stop of the first driving component provided on the gimbal base, and a second driving component for driving the longitudinal rotating seat to rotate provided on the mounting box.

[0005] Furthermore, the first drive assembly includes a first motor fixedly installed inside the mounting box, the output shaft of the first motor is fixedly connected to a transmission gear, and an external gear ring is fixedly connected to the outer side of the hollow shaft, the external gear ring meshing with the transmission gear.

[0006] Furthermore, the ratio of the number of teeth of the transmission gear to that of the external gear ring is 1:4.

[0007] Furthermore, the locking assembly includes a rotating wheel fixedly connected to the outside of the hollow shaft. The outer side of the rotating wheel has several slots arranged in a circular array. A rotating sleeve is rotatably connected to the outer side of the gimbal base. Several first connecting rods are rotatably connected to the inner wall of the rotating sleeve and are distributed at equal angles around the rotating sleeve. One end of each of the first connecting rods is hinged to a sliding rod. Each of the sliding rods passes through the side wall of the gimbal base and is slidably connected to the gimbal base. An elastic element is fixedly connected to the end of each of the sliding rods away from the first connecting rod. A locking block that slides with any one of the slots is fixedly connected to one end of each elastic element. The mounting box is provided with a linkage component that drives the rotating sleeve to rotate by coordinating with the start and stop of the first motor.

[0008] Furthermore, the horizontal interface of the card block has a fan-shaped structure, and the card slot has an arc-shaped structure.

[0009] Furthermore, the elastic element includes a sleeve fixedly connected to the end of the slide rod, one end of the sleeve is slidably connected to an insert rod, one end of the insert rod is fixedly connected to a locking block, the other end of the insert rod is fixedly connected to a guide block, the guide block is slidably connected to the inner wall of the sleeve, and a pressure spring is sleeved on the inner side of the sleeve, one end of the pressure spring abuts against the guide block, and the other end of the pressure spring abuts against the inner wall of the sleeve.

[0010] Furthermore, the pressure spring is initially in a compressed state and always applies elastic force to the guide block.

[0011] Furthermore, the linkage includes a support fixedly connected to the top of the mounting box, a movable rod slidably connected to the support, a connecting seat fixedly connected to one end of the movable rod, a second connecting rod rotatably connected to the top of the connecting seat, the end of the second connecting rod away from the connecting seat being rotatably connected to the outer edge of the bottom wall of the rotating sleeve, an iron block fixedly connected to the other end of the movable rod, and an electromagnet fixedly connected to one end of the support, the coil of the electromagnet being connected in series with the circuit of the first motor.

[0012] Furthermore, the second drive assembly includes a mounting bracket fixedly connected to the inside of the mounting box, a second motor fixedly mounted on the inside of the mounting bracket, a rotating shaft through which the output shaft of the second motor is fixedly connected, the rotating shaft being rotatably connected to a transverse rotating seat, a first bevel gear fixedly connected to the top of the rotating shaft, and a second bevel gear meshing with the first bevel gear being coaxially fixedly connected to the longitudinal rotating seat.

[0013] Furthermore, a power failure brake sleeved on the outside of the rotating shaft is fixedly connected to the top of the mounting bracket, and the coil of the power failure brake is connected in series with the circuit of the second motor.

[0014] The working principle and beneficial effects of this invention are as follows: 1. When the first motor is powered on and started, the electromagnet simultaneously engages, causing the locking block 467 to disengage and releasing the horizontal locking. When the first motor is powered off, the electromagnet loses power, and under the action of the return spring, the locking block automatically pops out and locks into the slot of the rotating wheel, achieving a mechanical lock in the horizontal direction. The de-energized brake coil in the second drive assembly is connected in series with the second motor circuit. When the motor is powered on, the brake is released, allowing adjustment. When the motor is powered off, the brake automatically engages, locking the rotating shaft and locking the pitch angle. This achieves a fully automatic logic of "unlocking upon driving and locking upon power failure," fundamentally eliminating the risk of heater position drift due to human negligence or system failure, and significantly improving operational safety.

[0015] 2. This invention uses multiple circumferentially distributed locking blocks that simultaneously engage with the locking slots to disperse the locking force, enhancing the stability and reliability of the locking mechanism. This avoids stress concentration or loosening that may occur with single-point locking. The elastic element contains a pressure spring that is always in a compressed state, which provides a buffer when the locking blocks are inserted into the locking slots, allowing it to adapt to minor alignment deviations and avoid rigid impacts. At the same time, the continuous pressure of the spring automatically compensates for wear caused by long-term use of the locking blocks or locking slots, maintaining effective locking force and preventing loosening.

[0016] 3. The present invention controls horizontal rotation through the first drive component and pitch angle through the second drive component. The two work together to achieve precise alignment of the infrared heater at multiple angles in space, adapting to the pipe processing needs of different positions and angles.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this invention.

[0022] like Figures 1 to 9 As shown, this embodiment proposes a multi-angle universal adjustment gimbal locking mechanism for an infrared heater made of tubing. It includes a base 1, a mounting box 2 fixedly connected to the top of the base 1, a gimbal base 3 fixedly connected to the top of the mounting box 2, an adjustment module 4 on the gimbal base 3, and a hollow shaft 41 penetrating the top wall of the gimbal base 3 and rotatably connected to it. A transverse rotating seat 42 is fixedly connected to the top of the hollow shaft 41, and a longitudinal rotating seat 43 is rotatably connected to the inner side of the transverse rotating seat 42. One end of the longitudinal rotating seat 43 is fixedly connected to a mounting plate 44 for fixing to the infrared heater 5. A first driving component 45 for driving the hollow shaft 41 to rotate is provided on the inner side of the gimbal base 3. A locking component 46 for locking the hollow shaft 41 by cooperating with the start and stop of the first driving component 45 is provided on the gimbal base 3. A second driving component 47 for driving the longitudinal rotating seat 43 to rotate is provided on the mounting box 2.

[0023] In this embodiment, when angle adjustment is required, the first drive component 45 operates, driving the hollow shaft 41 to rotate. The hollow shaft 41 drives the transverse rotating seat 42 on its top to rotate in the horizontal plane, thereby changing the horizontal orientation of the heater 5.

[0024] At the same time, the second drive assembly 47 operates, and its power is transmitted through the rotating shaft 472 that passes through the hollow shaft 41. The transmission direction is changed through the bevel gear pair, driving the longitudinal rotating seat 43 to rotate in a plane perpendicular to the transverse rotating seat 42, thereby changing the pitch angle of the heater 5.

[0025] By working together or independently, the heater 5 can be adjusted in multiple angles and in all directions in space. Once the adjustment is in place, the locking component 46 is activated to lock the hollow shaft 41 and fix the angle in the horizontal direction. This design combines two degrees of freedom, horizontal rotation and vertical pitch, to enable the infrared heater 5 to be precisely aligned with the pipe to be processed at different positions and angles, adapting to complex processing requirements. The main frame, consisting of the base 1, mounting box 2 and gimbal base 3, is compactly designed by integrating modules such as horizontal drive, locking, and pitch drive into the main frame.

[0026] In a further preferred embodiment of the present invention, the first drive assembly 45 includes a first motor 451 fixedly installed inside the mounting box 2. The output shaft of the first motor 451 is fixedly connected to a transmission gear 452. An external gear ring 453 is fixedly connected to the outer side of the hollow shaft 41. The external gear ring 453 meshes with the transmission gear 452. The tooth ratio of the transmission gear 452 to the external gear ring 453 is 1:4.

[0027] In this embodiment, the first motor 451 is started, and its output shaft drives the transmission gear 452 to rotate.

[0028] The transmission gear 452 meshes with the external gear ring 453 fixed on the outside of the hollow shaft 41, thereby converting the rotational motion of the motor into the rotational motion of the hollow shaft 41, driving the transverse swivel 42 to rotate. The gear ratio of the transmission gear 452 to the external gear ring 453 is 1:4, forming a reduction gear pair. The 1:4 gear ratio achieves speed reduction and amplifies the output torque of the first motor 451, making it more stable and powerful when driving the heater with a larger load to rotate horizontally. Moreover, the use of direct motor-gear connection results in fast control response, simple structure, and convenient maintenance.

[0029] In a further preferred embodiment of the present invention, the locking component 46 includes a rotating wheel 461 fixedly connected to the outside of the hollow shaft 41. The outer side of the rotating wheel 461 is provided with a plurality of slots 462 arranged in a circular array. The outer side of the gimbal base 3 is rotatably connected to a rotating sleeve 463. The inner wall of the rotating sleeve 463 is rotatably connected to a plurality of first connecting rods 464 arranged at equal angles around the rotating sleeve 463. One end of each of the plurality of first connecting rods 464 is hinged to a sliding rod 465. Each of the plurality of sliding rods 465 passes through the side wall of the gimbal base 3 and is slidably connected to the gimbal base 3. One end of each of the plurality of sliding rods 465 away from the first connecting rods 464 is fixedly connected to an elastic element 466. One end of each of the plurality of elastic elements 466 is fixedly connected to a locking block 467 that slides and engages with any one of the slots 462. The cross surface of the locking block 467 is a fan-shaped structure, and the slot 462 is an arc-shaped structure. The mounting box 2 is provided with a linkage element 468 that drives the rotating sleeve 463 to rotate by cooperating with the start and stop of the first motor 451.

[0030] In this embodiment, when the first motor 451 is de-energized and stops, the linkage 468 causes the rotating sleeve 463 to rotate.

[0031] The rotation of the rotating sleeve 463 is converted into linear motion of all the sliding rods 465 radially inward along the gimbal base 3 through several first connecting rods 464.

[0032] The slide bar 465 pushes the elastic element 466 and the locking block 467 at its end to move inward, so that the locking block 467 is inserted into the locking groove 462 on the outer periphery of the rotating wheel 461.

[0033] Since the rotating wheel 461 is fixed on the hollow shaft 41, the hollow shaft 41 is mechanically locked, preventing it from rotating due to external force or vibration.

[0034] When the first motor 451 is powered on and started, the linkage 468 causes the rotating sleeve 463 to rotate in the opposite direction, and pulls the slide rod 465 radially outward through the first connecting rod 464, thereby pulling the locking block 467 out of the slot 462, releasing the lock on the hollow shaft 41, and allowing it to rotate freely. This design is linked to the motor circuit to achieve "locking upon power failure," preventing the heater from shifting due to its own weight or external interference when the machine stops or is unexpectedly powered off. This ensures high safety. Multiple evenly distributed locking blocks 467 engage with the locking slots 462 simultaneously, dispersing the locking force and enhancing the reliability and stability of the lock. This avoids stress concentration or loosening that may occur with single-point locking. The linkage mechanism efficiently converts the rotational motion of the rotating sleeve 463 into the synchronous linear motion of multiple locking blocks 467. The locking and releasing actions are rapid and require almost no additional adjustment time.

[0035] In a further preferred embodiment of the present invention, the elastic element 466 includes a sleeve 4661 fixedly connected to the end of the slide rod 465. One end of the sleeve 4661 is slidably connected to an insert rod 4662. One end of the insert rod 4662 is fixedly connected to a locking block 467. The other end of the insert rod 4662 is fixedly connected to a guide block 4663. The guide block 4663 is slidably connected to the inner wall of the sleeve 4661. A pressure spring 4664 is sleeved on the inner side of the sleeve 4661. One end of the pressure spring 4664 abuts against the guide block 4663, and the other end of the pressure spring 4664 abuts against the inner wall of the sleeve 4661. The pressure spring 4664 is initially in a compressed state and always applies elastic force to the guide block 4663.

[0036] In this embodiment, the pressure spring 4664 is in a compressed state during initial installation, thereby continuously applying a pushing force to the guide block 4663, and then pressing the locking block 467 toward the rotating wheel 461 through the insert rod 4662.

[0037] When the locking block 467 needs to be inserted into the slot 462, under the combined action of the push of the slide rod 465 and the spring pressure, the locking block 467 can smoothly slide into the slot. If there is a slight misalignment, the compression of the spring can change slightly, allowing the insertion rod 4662 to expand and contract slightly within the sleeve 4661, thereby allowing the locking block 467 to adaptively engage in the slot, avoiding rigid impact. In the locked state, the continuous pressure of the spring ensures close contact between the locking block 467 and the side wall of the slot 462, eliminating gaps. The elasticity of the spring in this design provides a buffer during the locking process, avoiding rigid impacts and noise caused by manufacturing errors or minor displacements between the locking block 467 and the rotating wheel 461, thus improving the lifespan of the mechanism. After long-term use, the locking block 467 or the slot 462 may wear out. The continuous elastic force of the pressure spring 4664 can push the locking block 467 to automatically follow, compensating for the gap caused by wear, and always maintaining an effective locking force to prevent loosening.

[0038] In a further preferred embodiment of the present invention, the linkage 468 includes a support 4681 fixedly connected to the top of the mounting box 2, a movable rod 4682 slidably connected to the support 4681, a connecting seat 4683 fixedly connected to one end of the movable rod 4682, a second connecting rod 4684 rotatably connected to the top end of the connecting seat 4683, the end of the second connecting rod 4684 away from the connecting seat 4683 being rotatably connected to the outer edge of the bottom wall of the rotating sleeve 463, an iron block 4685 fixedly connected to the other end of the movable rod 4682, an electromagnet 4686 fixedly connected to one end of the support 4681, and the coil of the electromagnet 4686 being connected in series with the circuit of the first motor 451.

[0039] In this embodiment, when the first motor 451 is powered on and started, the electromagnet 4686 is also powered on at the same time, generating a magnetic force to attract the iron block 4685, which drives the movable rod 4682 to slide towards the electromagnet.

[0040] The movable lever 4682 drives the rotating sleeve 463 to rotate to the "unlocked" position via the connecting seat 4683 and the second connecting rod 4684.

[0041] When the first motor 451 is de-energized and stops, the electromagnet 4686 is also de-energized, and the magnetic force disappears.

[0042] Under the action of the return spring 4687, the movable rod 4682 is pushed back, and then the rotating sleeve 463 is driven to rotate to the "locked" position through the second connecting rod 4684. Throughout the process, the locking and releasing states of the locking component 46 are strictly synchronized with the start and stop states of the first motor 451 and automatically switched. This design features a simple circuit series connection, achieving logical interlocking between the drive and locking mechanisms. It requires no additional sensors or controllers, has a high degree of automation, and its control logic is extremely reliable. The circuit ensures that the mechanism "loosens when it can move and locks when it stops," fundamentally eliminating the safety risks of damage to the mechanism that may be caused by forcibly starting the motor in the locked state, or accidental movement of moving parts when they are not locked.

[0043] In a further preferred embodiment of the present invention, the second drive assembly 47 includes a mounting bracket 471 fixedly connected to the inner side of the mounting box 2. A second motor 476 is fixedly mounted on the inner side of the mounting bracket 471. The output shaft of the second motor 476 is fixedly connected to a rotating shaft 472 that passes through the hollow shaft 41. The rotating shaft 472 is rotatably connected to a transverse rotating seat 42. A first bevel gear 473 is fixedly connected to the top of the rotating shaft 472. A second bevel gear 474 that meshes with the first bevel gear 473 is coaxially fixedly connected to the longitudinal rotating seat 43. A power-off brake 475 sleeved on the outer side of the rotating shaft 472 is fixedly connected to the top of the mounting bracket 471. The coil of the power-off brake 475 is connected in series with the circuit of the second motor 476.

[0044] In this embodiment, the second motor 476 is activated to drive the rotating shaft 472 to rotate.

[0045] The first bevel gear 473 at the top of the shaft 472 rotates accordingly, driving the second bevel gear 474 meshing with it to rotate.

[0046] Since the second bevel gear 474 is fixed coaxially with the longitudinal rotating seat 43, it drives the longitudinal rotating seat 43 and the mounting plate 44 to rotate together, thereby realizing the pitch angle adjustment of the infrared heater 5; the coil of the power failure brake 475 is connected in series with the circuit of the second motor 476.

[0047] When the second motor 476 is powered on, the power failure brake 475 is released, allowing the shaft 472 to rotate freely; when the second motor 476 is powered off, the power failure brake 475 automatically engages, locking the shaft 472 by friction or mechanical engagement. This design utilizes a bevel gear pair to efficiently convert vertical input rotational motion into horizontal output rotational motion, making it ideal for vertical drive within space-constrained gimbal structures; the power-off brake 475 enables automatic locking of the pitch axis.

[0048] Its series connection with the motor circuit ensures that the pitch axis has the same "power off and lock" characteristic as the horizontal axis, so that the entire gimbal is reliably locked in both the horizontal and vertical dimensions when it is stationary, and has a very strong position holding capability.

[0049] Overall workflow: I. Initial Preparations: The entire system is in a static locked state. At this time, the locking block 467 of the locking component 46 is tightly locked into the slot 462 of the rotating wheel 461 fixed on the outside of the hollow shaft 41 under the continuous elastic force of the pressure spring 4664 inside the elastic member 466, thereby locking the hollow shaft 41 and the components above it in the horizontal direction. At the same time, the power failure brake 475 in the second drive component 47 automatically engages due to the power failure of the second motor 476, locking the rotating shaft 472, thereby locking the pitch angle of the longitudinal rotating seat 43.

[0050] At this point, the positions of the mounting plate 44 and the infrared heater 5 mounted on it are completely fixed; II. Horizontal adjustment: When it is necessary to adjust the horizontal angle of the infrared heater 5, the first motor 451 of the first drive assembly 45 is started.

[0051] When the first motor 451 is energized, the electromagnet 4686 in the linkage 468 connected in series with the circuit of the first motor 451 is also energized to generate magnetic force; the first motor 451 drives the transmission gear 452 to rotate, and the transmission gear 452 drives the hollow shaft 41, the transverse rotating seat 42 and all the upper structures (including the longitudinal rotating seat 43, the mounting plate 44 and the heater 5) mounted on it to rotate together in the horizontal plane through meshing with the external gear ring 453 on the hollow shaft 41.

[0052] The 1:4 tooth ratio between the transmission gear 452 and the external gear ring 453 serves to reduce speed and increase torque, making the rotation smoother. At the same time, when the electromagnet 4686 is energized, it attracts the iron block 4685, which drives the movable rod 4682, the connecting seat 4683 and the second connecting rod 4684 to move, thereby driving the rotating sleeve 463 to rotate.

[0053] The rotation of the rotating sleeve 463 is converted into synchronous linear motion of all the sliding rods 465 along the radial outward of the gimbal base 3 by several first connecting rods 464 that are distributed at equal angles.

[0054] The slide bar 465 drives the elastic element 466 and the locking block 467 at its end to move outward, so that the locking block 467 completely disengages from the slot 462 of the rotating wheel 461, thereby releasing the horizontal lock on the hollow shaft 41 and allowing it to rotate freely. III. Pitch Direction Adjustment: When it is necessary to adjust the pitch angle of the infrared heater 5, the second motor 476 of the second drive assembly 47 is started.

[0055] When the second motor 476 is energized, the coil of the power-off brake 475 connected in series with its circuit is energized, the brake is released, and the lock on the rotating shaft 472 is released; the second motor 476 drives the rotating shaft 472 to rotate.

[0056] The rotating shaft 472 passes through the hollow shaft 41, and the first bevel gear 473 at its top rotates accordingly.

[0057] The first bevel gear 473 drives the second bevel gear 474, which meshes with it, to rotate. Since the second bevel gear 474 is coaxially fixed with the longitudinal rotary seat 43, it drives the longitudinal rotary seat 43, the mounting plate 44 and the heater 5 to rotate around the axis on the transverse rotary seat 42, thereby realizing the adjustment of the pitch angle. When the infrared heater 5 is precisely aligned with the target pipe processing area through the above-mentioned horizontal and pitch adjustments, the operator stops the first motor 451 and the second motor 476. When the first motor 451 is de-energized, the electromagnet 4686 is simultaneously de-energized, the magnetic force disappears, and the linkage 468 is reset under the action of the return spring, etc., driving the rotating sleeve 463 to rotate in the opposite direction. The rotating sleeve 463 pushes all the sliding rods 465 radially inward through the first connecting rod 464. The sliding rods 465 push the locking block 467 through the elastic element 466, so that with the assistance of the pressure spring 4664, it automatically and tightly locks into the corresponding slot 462 on the rotating wheel 461, realizing mechanical locking in the horizontal direction. The pressure spring 4664 in the elastic element 466 can also compensate for wear and ensure reliable locking. When the second motor 476 is de-energized, the de-energized brake 475 is simultaneously de-energized and automatically engages, firmly locking the rotating shaft 472 through friction or mechanical means, thereby locking the pitch angle of the longitudinal rotating seat 43.

[0058] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
