Description

Technical Field

[0001] This invention belongs to the field of fiberglass protective component processing technology, specifically a fiberglass protective component processing positioning device and positioning method. Background Technology

[0002] Fiberglass protective components are protective parts made of fiberglass and its products as reinforcing materials and synthetic resin as the matrix material. They are lightweight, corrosion-resistant, high-strength, and relatively low-cost. Because these components need to be connected to other structures on the equipment, they are often processed by drilling or grooving. However, due to the high strength of fiberglass, it is necessary to fix them in place to prevent displacement during grooving, which could lead to deviations between the grooved position and the specified process position, resulting in assembly failure. In existing fixing solutions, the edges of the fiberglass are typically secured by a clamping mechanism. However, this method lacks flexibility in adjusting the position of the clamp, and when using a single measurement and positioning method, the measurement accuracy of the part to be processed is low, easily leading to positioning coordinate deviations and affecting processing accuracy. Furthermore, some simple positioning devices lack sufficient anti-slip structures, making it easy for workpieces to shift during the processing of fiberglass pipe protective components, resulting in dimensional deviations. Summary of the Invention

[0003] To address the problems mentioned in the background section, this invention provides a processing and positioning device and method for fiberglass protective components, which solves the problems in the prior art where the fixture cannot be flexibly adjusted, the anti-slip structure is insufficient, and the workpiece shifts, resulting in processing dimensional deviations.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a processing and positioning device for fiberglass protective components, comprising a bracket and fiberglass protective components, wherein a protective frame is installed on the top of the bracket, a positioning component is installed inside the protective frame, an adjustment component is installed on the inner wall of the protective frame, and a hydraulic component is installed inside the bracket; The positioning component includes a carrier box fixed inside the protective frame. The carrier box contains four hydraulic telescopic rods arranged in a circumferential array. One end of each hydraulic telescopic rod is located inside the carrier box and is fixed with a gear. The gear is rotatably installed inside the carrier box and the gears mesh with each other. Each of the hydraulic telescopic rods has a corner guard rotatably engaged at the other end, and a support rod is movably engaged on each of the two opposite surfaces inside the protective frame. Each pair of adjacent corner guards is movably engaged on the support rod. The adjustment component is installed on one of the support rods, and the adjustment component pulls two adjacent corner guards closer to or further apart from each other; The top of the carrier box is connected to the carrier plate by a spring, and the cylinder part of each of the hydraulic telescopic rods is connected to the hydraulic assembly through a rubber oil pipe; The hydraulic components can inject or extract hydraulic oil into the hydraulic telescopic rod through rubber hoses.

[0005] Preferably, each of the corner protectors has a rubber pad installed on its inner wall, the hydraulic telescopic rod is adapted to the corner of the fiberglass protective component, and the support rod restricts the two vertical surfaces of the corner protector to always be parallel to the side of the fiberglass protective component.

[0006] Preferably, the positioning assembly further includes a set of support rods inside the sliding protective frame, the top of which is fixedly connected to the cylinder portion of the hydraulic telescopic rod.

[0007] Preferably, the adjusting component includes a threaded rod that slides and penetrates the interior of the protective frame. A handle is fixedly installed at both ends of the threaded rod. The threaded rod is provided with two threaded grooves with opposite helical directions. The threaded rod is provided with two guide plates and is respectively connected to each threaded groove. The two guide plates are rotatably installed at the ends of two adjacent hydraulic telescopic rods.

[0008] Preferably, the positioning component further includes a protector, which includes a rubber layer covering the outside of the carrier box. The carrier box is provided with a slot for the movement of the hydraulic telescopic rod. The slots on each carrier box are respectively connected to the outside of one of the hydraulic telescopic rods by two sliders. The hydraulic telescopic rod passes through the rubber layer.

[0009] Preferably, the connection between the hydraulic telescopic rod and the rubber layer is made of metal, and the slider is connected to the ball shaft of the hydraulic telescopic rod.

[0010] Preferably, a metal rod that can move through the support box is installed at the bottom of the support plate, a guide plate is installed on the metal rod, and the rubber oil pipe is connected to the oil tank; The hydraulic assembly includes an oil tank, a threaded shaft is rotatably mounted on the top of the oil tank, and a directional disc is threadedly fitted at both the upper and lower ends of the outer periphery of the threaded shaft. The directional disc moves vertically on the oil tank, and a sealing disc is fixedly mounted on the portion of the outer periphery of the threaded shaft inside the oil tank. The sealing disc blocks the connection of the rubber oil pipe. A counterweight is installed on the lower directional disc, a sealing plate is installed inside the oil tank, and the bottom of the guide disc is connected to the sealing plate by a tension spring.

[0011] Preferably, the top of the sealing plate is filled with hydraulic oil between itself and the oil tank, the threaded grooves on the threaded shaft for the movement of the two directional discs have opposite helical directions, the gravity of the counterweight guides the lower directional disc to the bottom of the threaded shaft, and the upper directional disc is restricted by the threaded grooves to rise to the top of the threaded shaft.

[0012] Preferably, a protrusion is installed at the bottom of the guide plate, and the protrusion is adapted to the directional plate.

[0013] A positioning method for a processing positioning device for fiberglass protective components, comprising the following specific steps: S1: Prioritize hoisting the fiberglass protective components onto the bearing plate. Since the connection of the rubber oil pipe is blocked in the initial state of the closed plate, the hydraulic oil inside the oil tank cannot enter the hydraulic telescopic rod, and the sealing plate cannot be moved. The gravity of the fiberglass protective components presses the bearing plate down and the spring is compressed. The metal rod at the bottom of the bearing plate will pull the tension spring. S2. The fiberglass protective component eventually lowers the upper directional plate by the guide plate on the metal rod. The directional plate will drive the threaded shaft to rotate through the threaded groove, so that the sealing plate no longer blocks the connection of the rubber oil pipe. The tension spring pulls the sealing plate down and can draw the hydraulic oil in the hydraulic telescopic rod through the rubber oil pipe. S3. During this period, the hydraulic telescopic rod gradually retracts, and the corner protectors gradually come into contact with the edges and corners of the fiberglass protective component. Since the four gears are installed at equal angles and mesh with each other, when the threaded rod is rotated, the guide plate on it pulls the corresponding two corner protectors closer to each other, and the corresponding two hydraulic telescopic rods swing. The other two symmetrical hydraulic telescopic rods will also do the same action, and make the corner protectors on them completely fit into the edges and corners of the fiberglass protective component.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention, through the coordination of positioning components and other structures, places the fiberglass protective component on a support plate. The hydraulic assembly controls the retraction speed and distance of each hydraulic telescopic rod to be the same. By adjusting the component, two adjacent corner protectors are pulled closer to drive the corresponding hydraulic telescopic rod to swing. Due to the limitation of gears, the other two symmetrical hydraulic telescopic rods swing along a mirror trajectory with the same swing amplitude. The adjusting component controls the hydraulic telescopic rods to always be located at the corner of the fiberglass protective component. After the corner protectors are tightened to the corner of the fiberglass protective component, the center point of the fiberglass protective component remains unchanged, avoiding deviations in processing dimensions. It is also important to note that the corner of the fiberglass protective component is fixed by the corner protectors, which are connected to the hydraulic telescopic rods and driven by hydraulic oil to prevent the fiberglass protective component from slipping, thus better ensuring the accuracy during processing.

[0015] This invention, through the coordinated arrangement of positioning and hydraulic components, initially seals the rubber oil pipes with a closed disc. The fiberglass protective component is placed on a support disc, and gravity forces the support disc to descend. A guide disc then forces the upper directional disc to descend as well. The directional disc drives the threaded shaft to rotate via a threaded groove. The closed disc then releases the rubber oil pipes, and a tension spring pulls the sealing plate to draw hydraulic oil from the hydraulic telescopic rod, causing it to retract. This completes the positioning of the fiberglass protective component. Since the medium driving the extension and retraction of the hydraulic telescopic rod is hydraulic oil, when external force causes the fiberglass protective component to move on a plane, it must push the corner protector. The corner protector's movement must overcome the limitations of the threads on the threaded rod. Subsequently, the hydraulic oil in the hydraulic telescopic rod must be compressed back into the oil tank, or new hydraulic oil must be drawn from the oil tank to the hydraulic telescopic rod to achieve extension and retraction, thus driving the corner protector's movement. External force cannot achieve this, further solidifying the stability of the device's positioning of the fiberglass protective component and ensuring higher precision in subsequent processing.

Detailed Implementation

[0018] 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.

[0019] like Figures 1 to 9 As shown, the present invention provides a processing and positioning device for fiberglass protective parts, including a bracket 1 and a fiberglass protective part 6. A protective frame 2 is installed on the top of the bracket 1, a positioning component 3 is installed inside the protective frame 2, an adjustment component 5 is installed on the inner wall of the protective frame 2, and a hydraulic component 4 is installed inside the bracket 1. The positioning component 3 includes a carrier box 31 fixed inside the protective frame 2. Four hydraulic telescopic rods 34 arranged in a circumferential array are installed inside the carrier box 31. One end of each hydraulic telescopic rod 34 is located inside the carrier box 31 and is fixed with a gear 342. The gear 342 is rotatably installed inside the carrier box 31 and the gears 342 mesh with each other. Rubber pads are installed on the inner walls of each corner guard 35. The hydraulic telescopic rod 34 is adapted to the edges and corners of the fiberglass protective component 6. The support rod 36 restricts the two vertical surfaces of the corner guard 35 to always be parallel to the side of the fiberglass protective component 6.

[0020] Each hydraulic telescopic rod 34 has a corner guard 35 rotatably engaged at the other end. Inside the protective frame 2, each of the two opposite surfaces is movably engaged with a support rod 36. Every two adjacent corner guards 35 are movably engaged with the support rod 36. The adjustment component 5 is installed on one of the support rods 36. The adjustment component 5 pulls two adjacent corner guards 35 closer to each other or further apart. The top of the support box 31 is connected to the support plate 32 by a spring 33, and the cylinder part of each hydraulic telescopic rod 34 is connected to the hydraulic assembly 4 through a rubber oil pipe 341; The positioning component 3 also includes a set of support rods 36 inside the sliding protective frame 2, the top of which is fixedly connected to the cylinder portion of the hydraulic telescopic rod 34.

[0021] The hydraulic component 4 can supply or extract hydraulic oil to the hydraulic telescopic rod 34 through the rubber oil pipe 341.

[0022] Using the above scheme: In the initial state, the hydraulic component 4 does not extract the hydraulic oil from the hydraulic telescopic rod 34, and the end of the hydraulic telescopic rod 34 is connected to the support rod 36 through the corner guards 35. Each corner guard 35 is also located on the edge of the inside of the protective frame 2, so the hydraulic telescopic rod 34 cannot swing. When the fiberglass protective component 6 is placed on the support plate 32, the hydraulic assembly 4 draws hydraulic oil from the hydraulic telescopic rod 34 through the rubber oil pipe 341, causing the hydraulic telescopic rod 34 to retract. Since the hydraulic telescopic rod 34 is hinged to the inside of the support box 31 through gears 342, and each gear 342 is hinged to the others, when the adjusting assembly 5 pulls two adjacent corner protectors 35 closer together to drive the corresponding hydraulic telescopic rod 34 to swing, the other two symmetrical hydraulic telescopic rods 34 will swing in the same mirror trajectory. During this period, it is necessary to control the hydraulic telescopic rods 34 to always be located on the corners of the fiberglass protective component 6 through the adjusting assembly 5, so that the corner protectors 35 can finally move towards the corners of the fiberglass protective component 6 and gradually fit together. Since the four corner protectors 35 are... Due to the constraints of gear 342, the swing amplitude of the hydraulic telescopic rod 34 is the same at all four corners of the fiberglass protective component 6. Simultaneously, hydraulic oil is uniformly drawn from the hydraulic assembly 4 through the rubber oil pipe 341, so the movement trajectories of each corner guard 35 are identical. After the corner guard 35 is finally tightened to the edge of the fiberglass protective component 6, the center point of the fiberglass protective component 6 remains unchanged, thus facilitating subsequent processing and avoiding dimensional deviations after clamping, as is the case with existing solutions. It should also be noted that the edges of the fiberglass protective component 6 are fixed by the corner guard 35, which is connected to the hydraulic telescopic rod 34 and driven by hydraulic oil for extension and retraction. This further prevents slippage during the processing of the fiberglass protective component 6, better ensuring processing accuracy.

[0023] A preferred embodiment is the addition of a toothed plate that can move up and down. When the toothed plate moves down, it does not engage with any of the gears 342. When the adjusting component 5 controls the hydraulic telescopic rod 34 to coincide with the corner of the fiberglass protective part 6, the toothed plate moves up and engages with any of the gears 342 to restrict the movement of the gears 342. At this time, the hydraulic telescopic rod 34 cannot swing. When the hydraulic component 4 extracts hydraulic oil from the hydraulic telescopic rod 34 to retract the hydraulic telescopic rod 34, the adjusting component 5 controls the movement speed of the corner protector 35 to prevent the corner protector 35 from moving too fast and causing the corner of the fiberglass protective part 6 to be hit and ultimately damaged.

[0024] like Figures 1-6 As shown, the positioning component 3 also includes a protector 38, which includes a rubber layer 381 covering the outside of the carrier box 31. The carrier box 31 is provided with a slot for the movement of the hydraulic telescopic rod 34. The slots on each carrier box 31 are respectively connected to the outside of a hydraulic telescopic rod 34 through two sliders 382. The hydraulic telescopic rod 34 passes through the rubber layer 381.

[0025] The connection between the hydraulic telescopic rod 34 and the rubber layer 381 is made of metal, and the slider 382 is connected to the ball shaft of the hydraulic telescopic rod 34.

[0026] Using the above solution: In the formal working environment of processing fiberglass protective parts 6, dust or dust caused by drilling and grooving will inevitably be generated, and the synchronous swing of each hydraulic telescopic rod 34 is achieved by the meshing of its end gear 342. Therefore, the rubber layer 381 on the outer periphery of the carrier box 31 can effectively prevent external dust from entering the interior of the carrier box 31 through the slot on the carrier box 31 for the swing of the hydraulic telescopic rod 34, thereby accelerating the wear and tear of the gear 342 and further extending the service life of the gear 342, while reducing the number of times the staff need to maintain the gear 342. When the hydraulic telescopic rod 34 swings frequently, it may be pressed down by the fiberglass protective part 6 due to long-term operation and come into contact with the groove on the carrier box 31. In order to avoid friction between the outer periphery of the hydraulic telescopic rod 34 and the groove on the carrier box 31, the hydraulic telescopic rod 34 and the groove are connected by a slider 382, ​​which fills the gap between the hydraulic telescopic rod 34 and the groove, and avoids damage to the hydraulic telescopic rod 34 and abnormal noise caused by friction.

[0027] like Figures 1-6 As shown, the adjustment component 5 includes a threaded rod 51 that slides and penetrates inside the protective frame 2. A handle 52 is fixedly installed at both ends of the threaded rod 51. The threaded rod 51 is provided with two threaded grooves with opposite helical directions. The threaded rod 51 is provided with two guide plates 53 and is connected to each threaded groove respectively. The two guide plates 53 are rotatably installed at the ends of two adjacent hydraulic telescopic rods 34 respectively.

[0028] Using the above scheme: Since the guide plate 53 is also slidably attached to the support rod 36, when the threaded rod 51 is rotated by the handle 52, the two guide plates 53 on the threaded rod 51 can move towards each other or in opposite directions, and the speed and distance of movement are equal. In the initial state, the lines connecting the four corner guards 35 form an equilateral rectangle. When the hydraulic assembly 4 extracts hydraulic oil from the hydraulic telescopic rods 34, the retraction speed remains constant. When the threaded rod 51 is rapidly rotated to increase the movement speed of the guide plate 53, that is... Figure 5 As shown, the corner protector 35 can quickly approach the corner of the fiberglass protective component 6 so that the corner protector 35 forms a rectangle and ultimately fits the actual specifications of the fiberglass protective component 6. It should be noted that the width of the fiberglass protective component 6 needs to be close to the threaded rod 51 so as to control the adjustment component 5 to change the position of the corner protector 35.

[0029] like Figures 1-9 As shown, a metal rod 321 that can be moved through the support box 31 is installed at the bottom of the support plate 32, and a guide plate 322 is installed on the metal rod 321. A rubber oil pipe 341 is connected to the oil tank 41. The hydraulic assembly 4 includes an oil tank 41. A threaded shaft 42 is rotatably mounted on the top of the oil tank 41. A guide plate 43 is threaded on both the upper and lower ends of the outer periphery of the threaded shaft 42. The guide plate 43 moves vertically on the oil tank 41. A sealing plate 44 is fixedly mounted on the part of the outer periphery of the threaded shaft 42 located inside the oil tank 41. The sealing plate 44 blocks the connection of the rubber oil pipe 341. The bottom of the guide plate 322 is fitted with a protrusion that is compatible with the directional plate 43.

[0030] A counterweight 45 is installed on the lower directional plate 43, a sealing plate 46 is installed inside the oil tank 41, and the bottom of the guide plate 322 is connected to the sealing plate 46 by a tension spring 323.

[0031] Using the above scheme: In the initial state, the sealing plate 44 blocks the connection of the rubber oil pipe 341, so the hydraulic oil in the hydraulic telescopic rod 34 cannot enter the oil tank 41, and the sealing plate 46 cannot move. When the fiberglass protective part 6 is placed on the bearing plate 32, the gravity presses the bearing plate 32 down and compresses the spring 33, and the metal rod 321 at the bottom of the bearing plate 32 pulls the tension spring 323. When the fiberglass protective component 6 is fully lowered, the guide plate 322 on the metal rod 321 will press the upper directional plate 43 to descend. Since the directional plate 43 is restricted to vertical movement on the oil tank 41, the directional plate 43 will drive the threaded shaft 42 to rotate through the threaded groove, so that the sealing plate 44 will no longer block the connection of the rubber oil pipe 341. The tension spring 323 pulls the sealing plate 46 down and draws the hydraulic oil in the hydraulic telescopic rod 34 through the rubber oil pipe 341 to achieve the purpose of retracting the hydraulic telescopic rod 34. Therefore, when the fiberglass protective component 6 is completely placed on top of the bearing plate 32, the corner protector 35 will also be in close contact with the edges and corners of the fiberglass protective component 6, thus completing the positioning work of the fiberglass protective component 6. Since the medium driving the extension and retraction of the hydraulic telescopic rod 34 is hydraulic oil, when the external force causes the fiberglass protective component 6 to move on the plane, it will inevitably need to push the corner protector 35. The movement of the corner protector 35 must break through the limitation of the thread on the threaded rod 51. Then, the hydraulic oil in the hydraulic telescopic rod 34 must be compressed back into the oil tank 41 or new hydraulic oil must be drawn from the oil tank 41 to the hydraulic telescopic rod 34, so as to realize the extension and retraction of the hydraulic telescopic rod 34, which can drive the corner protector 35 to move. External force cannot achieve the above situation, which further consolidates the stability of the device in positioning the fiberglass protective component 6, and the accuracy of subsequent processing is better guaranteed.

[0032] During the positioning process, the upper directional plate 43 is pressed down by the guide plate 322, and the lower directional plate 43 rises due to the guidance of the threaded groove. After the processing is completed, the fiberglass protective part 6 is moved away from the bearing plate 32, and the tension spring 323 and the spring 33 are no longer subjected to gravity pressure, which can drive the sealing plate 46 and the bearing plate 32 to return to their initial positions. During this period, the hydraulic oil re-enters the hydraulic telescopic rod 34 through the rubber oil pipe 341 and returns to its initial state. Because a counterweight 45 is set on the lower directional plate 43, the lower directional plate 43 will naturally descend due to its weight, thereby guiding the upper directional plate 43 to rise and reset through the threaded groove. The threaded shaft 42 and the sealing plate 44 will also reset and seal the connection of the rubber oil pipe 341. However, during this period, because the hydraulic oil is relatively viscous and always returns to the hydraulic telescopic rod 34 through the rubber oil pipe 341, the sealing plate 44 cannot reset and seal due to the pressure of the hydraulic oil flow. When the device returns to the initial position completely, the hydraulic oil stops flowing, and the lower directional plate 43 will slowly fall and guide the sealing plate 44 to seal. At the same time, it is convenient for the next positioning operation to be started by the weight of the fiberglass protective part 6.

[0033] Hydraulic oil is filled between the top of the sealing plate 46 and the oil tank 41. The spiral directions of the threaded grooves on the threaded shaft 42 for the movement of the two directional discs 43 are opposite. The gravity of the counterweight 45 guides the lower directional disc 43 to the bottom of the threaded shaft 42, while the upper directional disc 43 is restricted by the threaded grooves to rise to the top of the threaded shaft 42.

[0034] A positioning method for a processing positioning device for fiberglass protective components, comprising the following specific steps: S1: Prioritize hoisting the fiberglass protective component 6 onto the bearing plate 32. Since the sealing plate 44 initially blocks the connection of the rubber oil pipe 341, the hydraulic oil inside the oil tank 41 cannot enter the hydraulic telescopic rod 34, and the sealing plate 46 cannot move. The gravity of the fiberglass protective component 6 presses the bearing plate 32 down and the spring 33 is compressed. The metal rod 321 at the bottom of the bearing plate 32 will pull the tension spring 323. S2, the fiberglass protective component 6 finally presses the upper directional plate 43 down through the guide plate 322 on the metal rod 321. The directional plate 43 will drive the threaded shaft 42 to rotate through the threaded groove, so that the sealing plate 44 no longer blocks the connection of the rubber oil pipe 341. The tension spring 323 pulls the sealing plate 46 down and can draw the hydraulic oil in the hydraulic telescopic rod 34 through the rubber oil pipe 341. S3. During this period, the hydraulic telescopic rod 34 gradually retracts, and the corner guards 35 gradually come into contact with the edges and corners of the fiberglass protective component 6. Since the four gears 342 are installed at equal angles in the circumference and mesh with each other, when the threaded rod 51 is rotated, causing the guide plate 53 on it to pull the corresponding two corner guards 35 closer to each other, the corresponding two hydraulic telescopic rods 34 swing, and the other two symmetrical hydraulic telescopic rods 34 will also make the same movement, so that the corner guards 35 on them completely come into contact with the edges and corners of the fiberglass protective component 6.
