Description

Technical Field

[0001] This invention relates to the field of insulator processing technology, and in particular to a rapid adhesive bonding and fixing device for line pin-type porcelain insulators. Background Technology

[0002] Line pin-type porcelain insulators are widely used in power transmission and distribution systems. In their production and processing, the gluing of the steel foot and the porcelain bushing is the core process that determines the overall structural strength, insulation performance and service life of the insulator.

[0003] Traditional insulator bonding processing mostly adopts a single vertical pressing method. During the operation, the steel foot is forcibly pressed into the cement adhesive inside the porcelain bushing by mechanical pressure. The bonding method is relatively simple and curing.

[0004] In actual production operations, this simple static pressing assembly method relies solely on unidirectional pressure to squeeze the adhesive. The cement adhesive can only passively fill the gaps under pressure, and cannot achieve sufficient flow, uniform spreading, and displacement filling inside the adhesive joint. Its fluidity is extremely poor. During the forced filling process, a large number of dense and tiny air bubbles are easily trapped and trapped at the corners and dead corners of the annular adhesive joint between the outer wall of the steel foot and the inner wall of the ceramic sleeve. At the same time, local adhesive filling gaps and local adhesive accumulation are likely to occur, directly causing uneven thickness of the overall adhesive layer and inconsistent adhesive joint tightness. After the adhesive is fully cured, the remaining internal air bubbles will form hollow defects. Uneven thickness of the local adhesive layer will lead to uneven stress. During long-term use, it is very easy to cause a series of quality problems such as adhesive layer cracking, delamination of the adhesive from the component, and peeling off. Summary of the Invention

[0005] This invention provides a rapid adhesive fixing device for line pin-type porcelain insulators, which solves the technical problems of existing traditional insulator adhesive fixing processes, which generally adopt a single static pressing method, resulting in poor adhesive flow, many residual air bubbles, uneven adhesive layer density, easy delamination and cracking, and poor finished product consistency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rapid adhesive fixing device for line pin-type porcelain insulators is provided, comprising a bracket, a floating mounting plate, a bearing cylinder, a drive box, and a timing pneumatic control cylinder;

[0007] A cylinder is fixedly installed on one side of the bracket, and the floating mounting plate is fixedly installed on the output end of the cylinder.

[0008] A rotary spindle is rotatably mounted on one side of a floating mounting plate, and a clamping seat is fixedly mounted at the bottom end of the rotary spindle;

[0009] The bearing cylinder is movably embedded in one side of the bracket, and a ceramic sleeve is placed inside the bearing cylinder. A lifting assembly for driving the bearing cylinder to rise vertically is provided on the inner side of the bracket.

[0010] The drive box is fixedly mounted on one side of the floating mounting plate. The drive box is equipped with a transmission component that can slide laterally. The transmission component is connected to the rotary spindle via gear engagement and is used to drive the rotary spindle to rotate.

[0011] The timing pneumatic control cylinder is fixedly installed on one side of the bracket.

[0012] Preferably, a guide rod is fixedly provided on the inner wall of the clamping seat, and two bidirectional threaded rods are symmetrically rotated and installed on both sides of the clamping seat. Two arc-shaped clamping plates are symmetrically threaded on the bidirectional threaded rods. The guide rods can form a precise lateral limiting constraint on the two sets of arc-shaped clamping plates, effectively avoiding the problems of clamping plate sliding offset, jamming and shaking. With the symmetrical thread structure of the bidirectional threaded rods, the two sets of clamping plates can be synchronously oriented and equidistantly displaced, and the steel foot center positioning clamping can be quickly completed.

[0013] Preferably, the two arc-shaped clamping plates are slidably sleeved on the outer surface of the guide rod, and an adjustment knob is fixedly provided at the end of the bidirectional threaded rod. A positioning cylinder is fixedly provided on one side of the clamping seat, and steel feet are limited and clamped on opposite sides of the two arc-shaped clamping plates. The steel feet are movably embedded in the inner wall of the positioning cylinder. The clamping distance can be easily and manually adjusted by adjusting the knob to adapt to the clamping and fixing of steel feet with different diameters. The vertical nesting limit of the positioning cylinder and the radial clamping limit of the arc-shaped clamping plates form a double-layer positioning structure.

[0014] Preferably, the transmission assembly includes a push plate, an elastic plate, and a gear shaft. The push plate is laterally slidably embedded in the inner wall of the drive housing. One side of the push plate is fixedly connected to one side of the inner wall of the drive housing via the elastic plate. A transmission rack is fixedly installed on one side of the push plate. The gear shaft is rotatably mounted on the top side of the floating mounting plate. The transmission assembly relies on pneumatic power to achieve automated lateral sliding transmission, eliminating the need for an additional motor drive. It completes the transmission operation using the equipment's own power system. Simultaneously, the elastic plate provides adaptive buffering and reset capabilities, effectively offsetting rigid impacts during transmission.

[0015] Preferably, a small gear that meshes with a transmission rack is fixedly sleeved on the outer surface of the gear shaft, and a large gear is fixedly sleeved on the outer surface of the rotary spindle. The large gear meshes with the small gear for transmission, and the number of teeth of the small gear is less than the number of teeth of the large gear, forming a speed reduction and torque amplification transmission structure. The meshing speed reduction structure with the small gear as the driving force and the large gear as the driven force can effectively reduce the spindle rotation speed and amplify the transmission torque. At the same time, the stable high-torque rotation can ensure that the steel foot agitates the adhesive material at a uniform speed, improve the uniformity of adhesive material spreading, and meet the requirements of high-precision and high-quality insulator adhesive bonding process.

[0016] Preferably, a base is fixedly provided at the bottom end of the bearing cylinder, and a support pad is fixedly installed at the top end of the bearing cylinder. The top surface of the support pad fits against the bottom end of the porcelain sleeve for support, which can protect and buffer the porcelain sleeve and prevent the porcelain sleeve from being damaged by pressure during the lifting process.

[0017] Preferably, the lifting assembly includes two symmetrically arranged drive cylinders, a piston plate, and a hinge seat; the two drive cylinders are fixedly mounted on the inner wall of the support, the piston plate is sealed and embedded in the inner wall of the drive cylinder, a transmission rod is fixedly mounted on one side of the piston plate, a return spring is movably sleeved on the outer surface of the transmission rod, a hinge seat is fixed to the outer end of the transmission rod, and a force transmission connecting rod is hinged between the two hinge seats and the base. The symmetrically arranged lifting cylinders and connecting rod structure on both sides can realize bidirectional synchronous force transmission lifting, balanced force without off-center load, and efficiently convert horizontal pneumatic power into vertical lifting power. The power conversion efficiency is high, the operation is stable, and the return spring can realize automatic reset after the operation is completed.

[0018] Preferably, the inner wall of the timing pneumatic control cylinder is provided with an air chamber, the inner wall of the air chamber is sealed and movably embedded with a pressure plate, the inner wall of the timing pneumatic control cylinder is slidably provided with an isolation plate, one side of the pressure plate is fixedly provided with an energy storage spring, and the top of the pressure plate is fixedly provided with a linkage rod. The energy storage spring causes the pressure plate to reset. The automatic opening and closing of the air circuit is realized by relying on a purely mechanical linkage structure, eliminating the traditional electronic control delay module and reducing equipment failure points and maintenance costs.

[0019] Preferably, the top of the linkage rod is fixedly connected to the floating mounting plate, and a pre-reserved gap is left between the pressure plate and the isolation plate to form a downward pressure delay triggering structure. The downward pressure stroke of the floating mounting plate is used to link the displacement of the pressure plate, and the operation sequence delay triggering is realized through the preset gap. The idle stroke alignment and effective glue stirring and lifting process are distinguished. The steel foot and the ceramic sleeve are accurately aligned and attached first, and then the glue stirring and lifting actions are started.

[0020] Preferably, the outer surface of the air chamber is provided with a first vent pipe and a second vent pipe. The first vent pipe is connected to the internal air cavity of the drive box. A distributor is installed at the end of the second vent pipe. Two branch air supply pipes are connected to both sides of the distributor. The two branch air supply pipes are respectively connected to the air inlet of the two drive cylinders. The distributor evenly distributes and stabilizes the pressure, ensuring that the air pressure and flow of the drive cylinders on both sides are completely consistent. This enables the dual-sided lifting components to start and stop synchronously and lift at the same amplitude, effectively avoiding the problems of ceramic sleeve tilting and uneven glue seam caused by unilateral lifting deviation.

[0021] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0022] This invention employs a single-cylinder, homogeneous power source combined with a purely mechanical, sequential pneumatic control structure. It eliminates the need for additional electronic sensors and power components, achieving a single downward stroke that simultaneously realizes three-dimensional composite reverse motion: vertical downward pressure of the steel foot, low-speed rotation and agitation of the adhesive, and slight lifting of the ceramic sleeve. Abandoning the traditional single static pressing mode, it utilizes the relative shear convection between the steel foot and the ceramic sleeve to actively drive the adhesive to flow fully and spread outwards, eliminating dead zones in the adhesive seams and expelling micro-air bubbles from within the adhesive layer. Simultaneously, a delayed trigger structure ensures precise timing of alignment followed by agitation and lifting. Combined with a symmetrical lifting structure on both sides and a gear reduction and buffer structure, the equipment operates smoothly and with uniform force, effectively preventing ceramic sleeve breakage, gear tooth damage, and adhesive layer tearing.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] like Figures 1 to 8 As shown, the present invention provides a rapid adhesive fixing device for line pin-type porcelain insulators, including a bracket 1, a floating mounting plate 2, a bearing cylinder 3, a drive box 4, and a timing pneumatic control cylinder 5; a cylinder 101 is fixedly installed on one side of the bracket 1, and the floating mounting plate 2 is fixedly installed at the output end of the cylinder 101; a rotary spindle 201 is rotatably disposed on one side of the floating mounting plate 2, and a clamping seat 202 is fixedly disposed at the bottom end of the rotary spindle 201; the bearing cylinder 3 is movably embedded in one side of the bracket 1, and a porcelain sleeve 103 is placed inside the bearing cylinder 3; a lifting assembly for driving the bearing cylinder 3 to be vertically lifted is disposed inside the bracket 1; the drive box 4 is fixedly disposed on one side of the floating mounting plate 2, and a transmission assembly that can slide laterally is disposed inside the drive box 4, and the transmission assembly is connected to the rotary spindle 201 through gear engagement for driving the rotary spindle 201 to rotate; the timing pneumatic control cylinder 5 is fixedly disposed on one side of the bracket 1.

[0034] In use, the support frame 1 serves as the base for the entire machine, providing overall support for the cylinder 101, the timing pneumatic control cylinder 5, and the lifting assembly. The cylinder 101, as the sole power output component, drives the floating mounting plate 2 to perform vertical lifting and reciprocating motion, thereby driving the rotary spindle 201, clamping seat 202, and the clamped workpiece mounted on the floating mounting plate 2 to move downwards and feed. The transmission assembly inside the drive box 4 receives pneumatic power and drives the rotary spindle 201 to rotate through gear transmission, giving the workpiece a rotational motion effect during the pressing process. The timing pneumatic control cylinder 5 can be synchronized with the pressing stroke of the floating mounting plate 2 to realize the sequential opening and closing of the pneumatic circuit, thereby synchronously controlling the transmission action of the drive box 4 and the start and stop action of the lifting assembly inside the support frame 1. The lifting assembly can drive the bearing cylinder 3 and the internal porcelain sleeve 103 to complete the vertical lifting action. Finally, under the power of a single cylinder, the composite gluing operation of pressing down, rotating, and reversing the porcelain sleeve is realized simultaneously, completing the precision gluing processing of the insulator steel foot and the porcelain sleeve.

[0035] In actual use, the device is placed at a designated station on the insulator gluing production line. The cylinder 101 is connected to the compressed air source in the workshop through an external air pipe, and a pressure regulating valve and a solenoid valve are connected in series in the air intake circuit to precisely control the pressing speed and stroke of the floating mounting plate 2.

[0036] Please see Figures 1 to 8 In one embodiment, a guide rod 203 is fixedly provided on the inner wall of the clamping seat 202, and a bidirectional threaded rod 204 is symmetrically rotatably installed on both sides of the clamping seat 202. Two arc-shaped clamping plates 205 are symmetrically threaded on the bidirectional threaded rod 204. The pitch of the positive and negative threads of the bidirectional threaded rod 204 is equal, and the direction of the threads at both ends is opposite, so as to ensure that the arc-shaped clamping plates 205 on both sides can move towards the center at the same linear speed, thereby achieving high-precision automatic centering.

[0037] Furthermore, two arc-shaped clamping plates 205 are slidably sleeved on the outer surface of the guide rod 203, and an adjustment knob 206 is fixedly installed at the end of the bidirectional threaded rod 204. A positioning cylinder 207 is fixedly installed on one side of the clamping seat 202. The steel foot 102 is clamped on the opposite side of the two arc-shaped clamping plates 205. The steel foot 102 is movably embedded in the inner wall of the positioning cylinder 207. Through the double limiting cooperation between the positioning cylinder 207 and the two arc-shaped clamping plates 205, the steel foot 102 can be vertically positioned and radially centered and clamped, preventing the steel foot 102 from shifting or shaking during the pressing and rotating of the adhesive, and ensuring that the steel foot 102 and the ceramic sleeve 103 always maintain coaxiality.

[0038] Please see Figures 1 to 8In one embodiment, the transmission assembly includes a push plate 401, an elastic sheet 402, and a gear shaft 404. The push plate 401 is laterally slidably embedded in the inner wall of the drive box 4. One side of the push plate 401 is fixedly connected to one side of the inner wall of the drive box 4 through the elastic sheet 402. A transmission rack 403 is fixedly installed on one side of the push plate 401. The gear shaft 404 is rotatably disposed on the top side of the two floating mounting plates. The elastic sheet 402 not only plays a reset role, but its own elastic deformation can also provide flexible buffer when the transmission rack 403 slides into place quickly, preventing the large gear 406 and the small gear 405 from rigidly impacting and damaging the teeth.

[0039] Furthermore, a small gear 405 that meshes with the transmission rack 403 is fixedly sleeved on the outer surface of the gear shaft 404, and a large gear 406 is fixedly sleeved on the outer surface of the rotary spindle 201. The large gear 406 meshes with the small gear 405 for transmission, and the number of teeth of the small gear 405 is less than the number of teeth of the large gear 406, forming a speed reduction and torque increase transmission structure. Through the speed reduction motion, the high-speed motion of the transmission rack 403 sliding rapidly laterally can be converted into the low-speed, high-torque rotational motion of the rotary spindle 201, so that the steel foot 102 rotates at a uniform and smooth speed during the gluing process, avoiding excessive speed that could cause adhesive splashing, adhesive layer disturbance and tearing, and ensuring stable mixing and uniform filling of the adhesive material.

[0040] Please see Figures 1 to 8 In one embodiment, a base 301 is fixedly provided at the bottom end of the bearing cylinder 3, and a support pad 308 is fixedly installed at the top end of the bearing cylinder 3. The top surface of the support pad 308 fits against the bottom end of the porcelain sleeve 103 for support, which can protect and buffer the porcelain sleeve 103 and prevent the porcelain sleeve 103 from being damaged by pressure during the lifting process.

[0041] Preferably, the support pad 308 is made of polyurethane or nylon, which has sufficient compressive strength to withstand the lifting force and a certain elastic deformation capacity to compensate for possible machining tolerances at the bottom of the ceramic sleeve 103.

[0042] Please see Figures 1 to 8In one embodiment, the lifting assembly includes two symmetrically arranged drive cylinders 302, piston plates 303, and hinge seats 306. The two drive cylinders 302 are fixedly installed on the inner wall of the bracket 1. The piston plates 303 are sealed and embedded in the inner wall of the drive cylinders 302. A transmission rod 304 is fixedly installed on one side of the piston plates 303. A return spring 305 is movably sleeved on the outer surface of the transmission rod 304. A hinge seat 306 is fixed at the outer end of the transmission rod 304. A force transmission connecting rod 307 is hinged between the two hinge seats 306 and the base 301. Through the double-sided symmetrical connecting rod lifting structure, the horizontal telescopic power can be stably converted into vertical lifting power. With the help of the return spring 305, the automatic rebound and reset can be achieved after the operation. The lifting force is uniform and the action is synchronous and stable throughout the process. It can provide a smooth upward displacement for the ceramic sleeve 103. With the rotation and downward pressing of the steel foot 102, a reverse convection stirring motion is formed.

[0043] Furthermore, the inner wall of the timing pneumatic control cylinder 5 is provided with an air chamber 502, and a pressure plate 504 is movably embedded in the inner wall of the air chamber 502. An isolation plate 501 is slidably provided on the inner wall of the timing pneumatic control cylinder 5. An energy storage spring 503 is fixedly provided on one side of the pressure plate 504, and a linkage rod 505 is fixedly provided on the top of the pressure plate 504. Pure mechanical linkage pneumatic control is achieved by relying on the downward stroke of the equipment itself, and precise control of the action timing can be achieved without additional electrical control or sensing components.

[0044] Furthermore, the top of the linkage rod 505 is fixedly connected to the floating mounting plate 2, and a gap is reserved between the pressure plate 504 and the isolation plate 501 to form a downward pressure delay trigger structure.

[0045] It is worth noting that when the device is powered on and in standby initial state, it is necessary to check whether the delay gap between the contact plate 504 and the isolation plate 501 inside the timing air control cylinder 5 meets the process requirements of the current model of insulator. If necessary, the gap can be adjusted by replacing the isolation plate 501 of different thicknesses, so as to adapt to the glue depth of different specifications of steel foot 102 and porcelain sleeve 103.

[0046] Please see Figures 1 to 8 In one embodiment, a first vent pipe 506 and a second vent pipe 507 are connected to the outer surface of the air chamber 502. The first vent pipe 506 is connected to the internal air cavity of the drive box 4. A distributor 508 is installed at the end of the second vent pipe 507. Two branch air supply pipes 509 are connected to both sides of the distributor 508. The two branch air supply pipes 509 are respectively connected to the air inlet of the two drive cylinders 302. The distributor 508 adopts a symmetrical flow channel design to ensure that the air pressure and flow rate of the air distributed to the two drive cylinders 302 are completely consistent, thereby ensuring that the force transmission connecting rod 307 is subjected to balanced force on both sides when lifting the bearing cylinder 3, and avoiding the porcelain sleeve 103 from breaking due to tilting caused by unilateral force.

[0047] Working principle and process:

[0048] When gluing the steel foot 102 and the porcelain sleeve 103, the upper end of the steel foot 102 is manually inserted into the inner wall of the positioning cylinder 207. The adjustment knob 206 is turned to drive the bidirectional threaded rod 204 to rotate. The bidirectional threaded rod 204 has a positive and negative thread structure, which drives the two left and right arc-shaped clamping plates 205 to slide horizontally relative to each other along the guide rod 203 to achieve automatic centering and clamp the steel foot 102 to the center position of the clamping seat 202. At the same time, the porcelain sleeve 103 is placed inside the bearing cylinder 3. The bottom of the porcelain sleeve 103 is supported by the support pad 308. The support pad 308 plays the role of insulation, anti-slip, buffering and anti-chipping of porcelain. At this time, the equipment is in the initial standby state.

[0049] At this time, the equipment is started, and cement adhesive is evenly filled into the glue opening at the upper end of the porcelain sleeve 103. At this time, the cylinder 101 on the side of the bracket 1 moves downward, which drives the floating mounting plate 2 to move vertically downward as a whole. The floating mounting plate 2 drives the rotary spindle 201, the clamping seat 202 and the clamped steel foot 102 to move downward in a straight line simultaneously, so that the steel foot 102 gradually approaches the glue opening at the upper end of the porcelain sleeve 103.

[0050] At the same time, during the downward pressing of the floating mounting plate 2, the linkage rod 505 fixed at the bottom is moved downward. The linkage rod 505 pushes the pressure plate 504 inside the timing air control cylinder 5 to slide downward. At this stage, there is still a gap between the pressure plate 504 and the isolation plate 501, which is a delayed empty stroke. The air chamber 502 is not sealed and there is no airflow output. At this time, the steel foot 102 only presses down and does not rotate, and the ceramic sleeve 103 remains stationary.

[0051] When the floating mounting plate 2 is pressed down to the set working stroke, the pressure plate 504 completely adheres to the isolation plate 501. As the cylinder 101 continues to press down slightly, the air inside the air chamber 502 is forcibly compressed, forming a high-pressure airflow, which is then output in two synchronous paths. The high-pressure airflow is introduced into the air chamber inside the drive box 4 through the first vent pipe 506. The air pressure directly pushes the push plate 401 to slide laterally against the elastic force of the elastic sheet 402. The push plate 401 drives the transmission rack 403 to move, and the transmission rack 403 meshes with and drives the pinion 405 to rotate. The small gear 405 is fixed on the gear shaft 404 and rotates actively. The small gear 405 has fewer teeth and a faster rotation speed. It meshes with the large gear 406 to reduce speed and rotate, forming a small gear driving a large gear to reduce speed and increase torque. The large gear 406 is fixedly sleeved on the outer circle of the rotary spindle 201. Therefore, it drives the rotary spindle 201, the clamping seat 202 and the clamping steel foot 102 to rotate synchronously at low speed. The steel foot 102 continuously presses the cement adhesive downward while rotating at low speed to stir the adhesive layer, avoiding the accumulation of adhesive and eliminating static pressing dead angles.

[0052] Another high-pressure airflow from the air chamber 502 enters the distributor 508 through the second vent pipe 507. The distributor 508 evenly divides the single airflow into two streams, which are then sent into the two sets of drive cylinders 302 through the left and right symmetrical branch air supply pipes 509. After the drive cylinders 302 are filled with air, they push the piston plate 303 to slide outward. The piston plate 303 drives the transmission rod 304 to extend outward and compress the return spring 305.

[0053] The hinge seat 306 at the outer end of the transmission rod 304 moves outward and pushes the base 301 obliquely through the hinged force transmission rod 307, converting the horizontal thrust into a vertical lifting force, causing the base 301 and the bearing cylinder 3 to rise slightly upward as a whole, which in turn drives the ceramic sleeve 103 inside the bearing cylinder 3 to rise slowly upward. Under the single downward force of the same cylinder 101, two sets of reverse compound movements are generated simultaneously: the steel foot 102 presses down and rotates, and the ceramic sleeve 103 rises upward. The annular rubber seam between the steel foot 102 and the ceramic sleeve 103 generates a relative shearing and convection stirring effect, which completely squeezes out the large and small air bubbles wrapped inside the rubber layer, making the rubber layer dense and uniform in thickness.

[0054] After the adhesive mixing, venting, and pressure holding operations are completed, wait for the adhesive to solidify. Then, rotate the adjusting knob 206 in the opposite direction to rotate the bidirectional threaded rod 204, causing the arc-shaped clamping plates 205 on both sides to release the steel feet 102. At this time, the cylinder 101 retracts upward, driving the floating mounting plate 2 to move upward and reset as a whole. The linkage rod 505 simultaneously pulls up the pressure plate 504, opening the internal space of the air chamber 502 and completely releasing the air pressure. The air pressure inside the drive cylinder 302 disappears, and the return spring 305 rebounds and pushes the piston plate. 303. The transmission rod 304 resets, and the force transmission link 307 falls back down, causing the bearing cylinder 3 and the porcelain sleeve 103 to fall back to their initial low positions. At the same time, the elastic plate 402 inside the drive box 4 retracts and resets, pulling the push plate 401 and the transmission rack 403 back to their positions, driving the pinion 405 and the gear 406 to rotate and reset. The steel foot 102 stops rotating and returns to its initial position. The steel foot 102 and the porcelain sleeve 103, which have completed the gluing fit, are taken out as a whole, completing one complete gluing operation cycle.
