Description

Technical Field

[0001] This utility model belongs to the field of hinge processing technology, and in particular relates to a high-stability hinge processing positioning device. Background Technology

[0002] Cylindrical hinges are a common type of hinge, characterized by their cylindrical shape. They are typically used to connect and fix two components, allowing them to rotate relative to each other around the cylindrical axis. They are mainly installed on doors and windows. Cylindrical hinges require two external connecting plates for installation on doors and windows.

[0003] While existing technologies include positioning devices for cylindrical hinges, certain shortcomings still exist in their overall use:

[0004] First, when welding the hinges, there is a lack of an effective and fast positioning and clamping mechanism, which requires manual operation by the operator, increasing the labor intensity. At the same time, manual operation is prone to errors, which leads to a decline in product quality and greatly reduces the effectiveness of use.

[0005] Secondly, after the hinge is welded, welding slag remains on the surface. If it is not removed in time, it will affect the appearance and quality of the hinge. Manually cleaning the welding slag is prone to incomplete cleaning, which greatly increases the labor intensity and reduces the work efficiency. Utility Model Content

[0006] This invention addresses the technical problems of lacking an effective and rapid positioning and clamping mechanism during hinge welding and the presence of weld slag on the hinge surface after welding, which, if not treated promptly, affects the aesthetics and quality of the hinge. It provides a highly stable hinge processing positioning device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-stability hinge processing and positioning device, comprising a base, wherein two symmetrically arranged clamping plates are slidably mounted on the upper surface of the base, and a positioning mechanism is slidably mounted on the opposite side of the clamping plates for quickly and stably positioning the hinge.

[0008] A bracket is fixedly installed on the upper surface of the base, a blade holder is slidably installed on the opposite side of the bracket, and a punching blade is fixedly installed at the bottom of the blade holder.

[0009] A fourth fixing plate is fixedly installed on one side of the tool holder, a telescopic rod is fixedly installed on the lower surface of the fourth fixing plate, a striking head is fixedly installed on the piston end of the telescopic rod, and a spring is fixedly installed on the lower surface of the fourth fixing plate on the outer side of the telescopic rod.

[0010] An air nozzle is fixedly installed on the opposite side of the clamping plate.

[0011] The cutting blade moves downward to cut the sheet metal. At the same time, the blade holder moves the fourth fixed plate downward, which in turn moves the hammering head downward. The welded joint of the hinge is first struck and vibrated to knock off the weld slag. The air nozzle blows the slag into the collection box. The hammering of the welded part during the cutting process causes the weld slag to fall off, which increases the speed of weld slag removal and processing speed, and greatly improves work efficiency.

[0012] In the above-mentioned high-stability hinge processing and positioning device, the positioning mechanism includes a limiting plate slidably installed on the opposite side of the clamping plate, an arc-shaped support plate fixedly installed at the bottom of the limiting plate, and two symmetrically arranged clamping blocks slidably installed on both sides of the limiting plate. The surface of the clamping blocks is made of flexible material and has a serrated surface.

[0013] By using a support plate to hold the hinge in place, it is possible to quickly connect the components while achieving stable positioning, thus improving the welding effect and increasing work efficiency.

[0014] In the aforementioned high-stability hinge processing and positioning device, the side thread of the clamping plate is fitted with a limiting button to limit the position of the limiting plate.

[0015] The limit button is used to limit the position of the limit plate, which facilitates the positioning of different types of hinges.

[0016] In the above-mentioned high-stability hinge processing and positioning device, a sliding groove is provided on the upper surface of the base, and a bidirectional lead screw is rotatably installed inside the sliding groove. Two symmetrically arranged sliders are threaded on the surface of the bidirectional lead screw.

[0017] By rotating the bidirectional lead screw, the slider is moved to center, which in turn drives the slider to center, thereby enabling the clamping plate to center and hold the hinge, quickly completing the positioning and improving stability.

[0018] In the above-mentioned high-stability hinge processing and positioning device, a conveying groove is provided on the side of the base away from the slide groove. Two sets of multiple rollers are rotatably installed on the upper and lower opposite surfaces of the conveying groove. A plate is provided between the two sets of rollers. A conveying wheel for conveying the plate is rotatably installed on the side of the base.

[0019] The plates are conveyed forward by conveyor wheels, eliminating the need for manual feeding and greatly improving work efficiency.

[0020] In the aforementioned high-stability hinge processing and positioning device, a pressure plate for limiting the position of the plate is slidably installed on the side of the base near the conveyor wheel.

[0021] After the plates are conveyed, the pressure plate presses against the plates to limit and fix them, thereby improving stability and welding effect.

[0022] In the aforementioned high-stability hinge processing and positioning device, an image detection module is fixedly installed on the surface of the tool holder.

[0023] The image detection module is used to check whether the weld slag at the hinge weld has completely fallen off.

[0024] In the aforementioned high-stability hinge processing and positioning device, a collection box is slidably installed in the middle of the base.

[0025] The collection box allows for the centralized processing of welding slag and waste materials from plate punching.

[0026] In the aforementioned high-stability hinge processing and positioning device, the slider and the clamping plate are hinged to each other.

[0027] The slider and clamp are hinged together, allowing the hinge to rotate after welding, which facilitates the storage and collection of finished products and improves the usage effect.

[0028] In summary, compared with the prior art, the high-stability hinge processing and positioning device provided by this utility model has the following beneficial effects:

[0029] 1. This utility model, through the setting of clamping plate, air nozzle, knife holder, telescopic rod, striking head and spring, can cut the connecting plate of the hinge without manual feeding, which greatly speeds up the work efficiency. At the same time as cutting the connecting plate, the weld of the hinge can be struck, so that the weld slag can automatically detach from the weld, which greatly improves the work efficiency.

[0030] 2. This utility model, through the setting of clamping plate, limiting plate, support plate, clamping block, etc., can position hinges of different sizes, which greatly improves the use effect. At the same time, it can reinforce the side and further improve stability, so that the hinge remains stable during the welding process, which greatly improves the use effect and ensures the quality of the finished product.

Detailed Implementation

[0038] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0039] refer to Figure 1 and Figure 2 A high-stability hinge processing and positioning device includes a base 10. A groove 11 is formed on the upper surface of the base 10. A bidirectional lead screw 12 is rotatably installed inside the groove 11. Two symmetrical sliders 14 are threaded on the two surfaces of the bidirectional lead screw 12. The sliders 14 slide inside the groove 11. A servo motor 13 that drives the bidirectional lead screw 12 is fixedly installed on one side of the base 10. When the servo motor 13 drives the bidirectional lead screw 12 to rotate, the sliders 14 move in the center.

[0040] Further reference Figures 1-4 A clamping plate 15 is rotatably mounted on the surface of the slider 14. A limiting plate 16 is slidably mounted on the opposite side of the clamping plate 15. A limiting button 17 is threadedly mounted on one side of the clamping plate 15. An arc-shaped support plate 18 is fixedly mounted on the bottom of the limiting plate 16. In use, the limiting plate 16 can slide on the surface of the clamping plate 15, thereby adjusting the height of the support plate 18 to facilitate the use of different types of hinges. After adjustment, the limiting plate 16 can be abutted by rotating the limiting button 17 to complete the limiting.

[0041] Further reference Figure 3Two symmetrically arranged first fixing plates 19 are fixedly installed on the opposite side of the clamping plate 15 and on both sides of the limiting plate 16. A miniature cylinder 20 is fixedly installed on the opposite side of the first fixing plate 19. A clamping block 21 is fixedly installed at the output end of the miniature cylinder 20. The clamping block 21 is made of flexible material and has a serrated surface, which can prevent damage to the hinge and increase friction, making the hinge clamping more comfortable. When positioning the hinge, the hinge is placed on the push plate to facilitate the docking of the two hinge components and speed up the work. Then the miniature cylinder 20 pushes the clamping block 21 to fix the hinge.

[0042] Further reference Figure 4 and Figure 5 Two conveying grooves 23 are provided on the side of the base 10 away from the slide groove 11. Two sets of multiple rollers 24 are rotatably installed on the downward opposite surfaces of the conveying grooves 23. A plate 25 is provided between the two sets of rollers 24. Two symmetrical second fixing plates 26 are fixedly installed on the side of the base 10 below the conveying grooves 23. A conveying motor 27 is fixedly installed on the opposite surface of the second fixing plates 26. A conveying wheel 28 for conveying the plate 25 is fixedly installed at the output end of the conveying motor 27. When in use, the conveying motor 27 drives the conveying wheel 28 to rotate, so that the conveying wheel 28 conveys the plate 25 forward, so that the plate 25 contacts the positioning hinge, which facilitates the subsequent welding work.

[0043] Further reference Figure 5 A third fixing plate 29 is fixedly installed above the conveying trough 23 on the side of the base 10. A pressure plate 30 is slidably installed below the third fixing plate 29 on the side of the base 10. A knob 31 is installed inside the third fixing plate 29 and is fixed to the pressure plate 30. The knob 31 rotates with the pressure plate 30. When in use, rotating the knob 31 causes the knob 31 to move downward in the third fixing plate 29, thereby causing the pressure plate 30 to slide downward and press down on the plate 25 to fix the plate 25. This ensures that the hinge remains stable when welding with the plate 25 and improves the welding effect.

[0044] Further reference Figure 1 , Figure 2 and Figure 4 A bracket 32 ​​is fixedly installed on the upper surface of the base 10. A hydraulic cylinder 33 is fixedly installed on the top of the bracket 32. The output end of the hydraulic cylinder 33 passes through the bracket 32 ​​and rotates. A tool holder 34 that slides on the surface of the hydraulic cylinder 33 is fixedly installed at the end. A punching blade is fixedly installed at the bottom of the tool holder 34. After the hinge is welded to the plate 25, the hydraulic cylinder 33 drives the tool holder 34 to move downward, thereby causing the punching blade to move down and cut the plate 25.

[0045] Further reference Figure 1 and Figure 6Two sets of fourth fixing plates 35 are fixedly installed on one side surface of the tool holder 34. The fourth fixing plates 35 are located above the plate 25. A telescopic rod 36 is fixedly installed on the lower surface of the fourth fixing plate 35. A spring 38 is fixedly installed on the outer side of the telescopic rod 36 on the lower surface of the fourth fixing plate 35. A striking head 37 is fixedly installed on the piston end of the telescopic rod 36. When the plate 25 is punched, the tool holder 34 drives the fourth fixing plate 35 to move down, thereby causing the striking head 37 to move down, first striking and vibrating the welded joint of the hinge to knock off the weld slag.

[0046] Further reference Figure 2 , Figure 3 and Figure 6 An image detection module 39 is fixedly installed on the surface of the tool holder 34 between the two striking heads 37. The image detection module 39 is existing technology and will not be described in detail in this solution. It is used to detect whether the welding slag at the welding point has completely fallen off. An air nozzle 40 is provided on the opposite side of the clamping plate 15. The air nozzle 40 is connected to an external air blowing device. Air blowing is existing technology and will not be described in detail in this solution. It is used to blow off the welding slag. A slot is opened on the surface of the base 10 at the welding point of the hinge to facilitate air circulation and timely heat dissipation during welding. A collection box 41 is slidably installed inside the slot to collect welding slag and punching waste, which is convenient for the removal and disposal of waste.

[0047] Further reference Figure 1 and Figure 4 A rotary motor 22 for driving the clamping plate 15 is fixedly installed on the outside of the slider 14. It is used to rotate the clamping plate 15. After welding is completed, the clamping plate 15 is rotated to collect the welded hinge.

[0048] Working principle: During operation, the hinge is placed on the support plate 18. Then, the micro cylinder 20 drives the clamping block 21 to position the hinge. Then, the servo motor 13 is controlled to work, driving the clamping plate 15 to move in the center and connect the two parts of the hinge. After the connection is completed, the conveying motor 27 works to drive the conveying wheel 28 to rotate, thereby conveying the plate 25 forward until the plate 25 and the hinge reach a suitable welding position for welding. After welding, the hydraulic cylinder 33 drives the knife holder 34 to move downward, causing the striking head 37 to strike the plate 25, causing the weld slag to fall off. Then, the punch cutter cuts the plate 25, and the air nozzle 40 blows the weld slag into the collection box 41. Then, the image detection module 39 detects the weld. After the quality is qualified, the rotary motor 22 drives the clamping plate 15 to rotate for unloading.
