Description

Technical Field

[0001] This utility model relates to the field of steel purlin processing technology, specifically a polishing structure for processing roof steel purlins. Background Technology

[0002] Polishing is a crucial step in the production and processing of steel purlins. After initial processing such as cutting and welding, burrs and flash often appear at the ends of the steel purlins. These defects not only affect the appearance quality of the steel purlins, but more importantly, they can have many adverse effects on subsequent installation and use. For example, burrs and flash may scratch construction workers during installation, or affect the tightness and stability of the connection when connected to other components. Therefore, polishing the ends of steel purlins can effectively remove these defects, improve the surface quality of the steel purlins, and ensure their installation accuracy and performance.

[0003] In actual polishing operations, due to the varying shapes and processing requirements of steel purlins, the angles of the polishing components need to be flexibly adjusted to meet the polishing needs of different parts. However, many existing polishing equipment have significant limitations in angle adjustment. Some equipment has fixed polishing component angles that cannot be adjusted at all, and can only polish the ends of steel purlins at specific angles. Other equipment, although possessing certain angle adjustment functions, has a cumbersome adjustment process that requires operators to have a high level of technical skill and rich experience, and the adjustment accuracy is difficult to guarantee. This undoubtedly increases the difficulty and cost of polishing operations. Therefore, we need to propose a polishing structure for processing roof steel purlins. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: A polishing structure for processing roof steel purlins includes a base plate 1; a protective shell 2 installed on the top of the base plate 1, with an inlet and outlet 3 on one side wall of the protective shell 2; a fixing mechanism 4 installed on the surface of the base plate 1 for clamping and fixing the steel purlins; and a polishing mechanism 5 installed on one side of the fixing mechanism 4 for polishing the ends of the clamped and fixed steel purlins.

[0019] The protective shell 2 serves as a protective and isolation function. It is made of stainless steel plate of moderate thickness, bent and welded, and has a certain strength and corrosion resistance. The dimensions of the inlet and outlet 3 are precisely designed to facilitate the entry and exit of the steel purlins and reduce the spillage of dust during the polishing process to a certain extent. A transparent observation window is set on one side of the protective shell 2, which makes it easy for operators to operate and observe the polishing of the steel purlins. The protective shell 2 encloses the polishing work area, which not only protects the operators from the injury of flying debris that may be generated during the polishing process, but also effectively reduces the impact of noise on the surrounding environment. In an optional embodiment: the polishing mechanism 5 includes a rotating plate 51, a cross slide 52 is fixedly mounted on the top of the rotating plate 51, a polishing component for polishing steel purlins is mounted on the surface of the top moving end of the cross slide 52, and a rotating component 57 for adjusting the polishing angle of the polishing component is mounted on the bottom of the rotating plate 51.

[0020] It should be noted that the cross slide 52 adopts a combination structure of ball screw and linear guide, which has the advantages of high-precision positioning, high-speed movement, high repeatability and strong load capacity. For example, the ball screw cross slide of Foyu can be selected. It is made of high-quality aluminum alloy, with a compact and sturdy structure, smooth movement and durability. With the controller, it can realize high-precision two-dimensional motion control. Through the movement of the top moving end of the cross slide 52, the position of the polishing component in the horizontal direction can be precisely adjusted to meet the polishing needs of different parts of the steel purlin, which greatly improves the flexibility and accuracy of polishing.

[0021] In an optional embodiment: the rotating assembly 57 includes a groove 571 formed on the surface of the base plate 1, a turntable bearing 572 is fixedly installed inside the groove 571, the rotating plate 51 is fixedly installed on the top of the turntable bearing 572, and a rotating motor 573 is fixedly installed on the bottom of the base plate 1. One end of the output shaft of the rotating motor 573 passes through the base plate 1 and through the inner ring of the turntable bearing 572 and is fixedly connected to the rotating plate 51.

[0022] It should be noted that the turntable bearing 572 can be a single-row four-point contact ball turntable bearing, such as the product of the 01 series. It has a compact structure, light weight, and four-point contact between the steel balls and the arc raceway, which can simultaneously withstand axial and radial forces. It has high load-bearing capacity and good rotational accuracy, which can ensure the stability and accuracy of the rotating plate 51 during rotation. The rotating motor 573 can be a DC motor, such as a brushless DC motor. The model can refer to some products with characteristics such as high speed, sensitive response, convenient control, high efficiency, and light weight. By rotating the rotating motor 573 in both directions, the rotating plate 51 can be driven to rotate around the central axis of the turntable bearing 572, thereby realizing the adjustment of the polishing angle of the polishing component. It can meet the polishing needs of different angles of the steel purlins and greatly improve the versatility of the equipment.

[0023] In an optional embodiment: the base plate 1 has limit grooves 574 on both sides of the groove 571, and limit blocks 575 are slidably installed inside the two sets of limit grooves 574. The tops of the two sets of limit blocks 575 are fixedly connected to the bottom of the rotating plate 51.

[0024] It should be noted that the combined use of the limiting groove 574 and the limiting block 575 limits the rotation angle of the rotating plate 51, preventing the rotating plate 51 from rotating excessively and ensuring the safety and stability of the equipment operation.

[0025] In an optional embodiment: the polishing assembly includes a mounting plate 53, which is fixedly mounted on the surface of the top movable end of the cross slide 52, and a rotating shaft 54 ​​is rotatably mounted on the mounting plate 53 via a bearing. One end of the rotating shaft 54 ​​passes through the mounting plate 53 and is fixedly connected to a polishing motor 55, and the other end is fixedly mounted with a polishing disc 56.

[0026] It should be noted that the polishing motor 55 can be a high-speed polishing motor, such as the Kasite grinding and polishing spindle, model SycoTec 4029, with a speed range of 5,000–60,000 min⁻¹ and a maximum power of 250W. It features high speed and high precision, providing stable and high-speed rotational power to the polishing disc 56. This allows the polishing disc 56 to quickly and effectively remove imperfections from the surface of the steel purlin during the polishing process, improving polishing efficiency and quality. At the same time, its high precision ensures that the surface finish of the polished steel purlin reaches a high standard. The polishing disc 56 can be equipped with sandpaper or polishing wheels of different materials and grits to meet different polishing requirements for steel purlin polishing operations.

[0027] In an optional embodiment: the fixing mechanism 4 includes a mounting shell 41, which is fixedly mounted on the top of the base plate 1. Two bidirectional threaded rods 42 are rotatably mounted on the inner walls of both sides of the mounting shell 41 via bearings. One end of the bidirectional threaded rod 42 passes through the mounting shell 41 and is fixedly connected to a fixing motor 43. Sliding protrusions 44 are threadedly mounted on the outer walls of both ends of the bidirectional threaded rod 42. The tops of the two sets of sliding protrusions 44 pass through the mounting shell 41 and are respectively connected to L-shaped clamps 45.

[0028] It should be noted that the fixed motor 43 can be a three-phase asynchronous motor of model Y90S-4, which has the advantages of simple structure, reliable operation and low cost. It can provide stable power output for the bidirectional threaded rod 42 and drive the bidirectional threaded rod 42 to rotate in both directions. When the bidirectional threaded rod 42 rotates, due to the characteristics of its bidirectional thread, the two sets of sliding protrusions 44 will move in opposite directions along the axial direction of the bidirectional threaded rod 42. Through the movement of the sliding protrusions 44, the L-shaped clamping plate 45 is driven to clamp or loosen the steel purlin. This method of cooperation between the bidirectional threaded rod 42 and the sliding protrusions 44 can achieve precise clamping of steel purlins of different sizes, and the clamping force is uniform and stable. It can effectively prevent the steel purlin from shifting or shaking during the polishing process and ensure the polishing effect.

[0029] It is worth noting that the surfaces of the two sets of L-shaped clamps 45 horizontal plates are at the same horizontal level as the inner bottom of the inlet and outlet 3.

[0030] In an optional embodiment: two sets of sliding protrusions 44 are slidably inserted into a limiting rod 47 on one side of the bidirectional threaded rod 42, and both ends of the limiting rod 47 are fixedly connected to the inner walls of both sides of the mounting shell 41.

[0031] It should be noted that the limiting rod 47 can prevent the sliding protrusion 44 from rotating on its own when it rotates with the bidirectional threaded rod 42, ensuring that the sliding protrusion 44 can only move linearly along the axis of the bidirectional threaded rod 42, thereby ensuring the reliability of the fixing mechanism 4.

[0032] In an optional embodiment: the top of the mounting shell 41 is symmetrically provided with two sets of sliding grooves 46, the tops of the two sets of sliding protrusions 44 are respectively located inside the two sets of sliding grooves 46, and the outer wall of the sliding protrusions 44 is slidably connected to the inner wall of the sliding grooves 46.

[0033] It should be noted that the groove 46 provides guidance for the movement of the sliding protrusion 44, further improving the smoothness and accuracy of the movement of the sliding protrusion 44.

[0034] In an optional embodiment, a dust extraction mechanism 6 is also included, mounted on top of the protective housing 2, for extracting dust generated during the polishing of the steel purlins; The dust collection mechanism 6 includes a dust collection box 61, which is fixedly installed on the top of the protective shell 2. The air inlet of the dust collection box 61 is fixedly connected to a dust collection hood 62 through a pipe. The dust collection hood 62 is fixedly embedded in the top of the protective shell 2. The air outlet of the dust collection box 61 is fixedly connected to a suction shell 63. A dust collection fan 64 is fixedly installed at the top air outlet of the suction shell 63, and a filter screen 65 is fixedly installed at the air inlet of the suction shell 63.

[0035] It should be noted that the shape and position of the dust hood 62 are carefully designed to maximize the collection of dust generated during the polishing process and reduce the spread of dust inside the protective shell 2. The dust collector 64 can be a 4-72 type centrifugal fan, which has a high air volume and air pressure and can provide strong suction to ensure that the dust inside the protective shell 2 is effectively sucked into the dust collection box 61. The filter 65 can be a fine stainless steel filter, which can effectively filter dust, prevent dust from entering the dust collector 64, protect the normal operation of the dust collector 64, and extend its service life.

[0036] In an optional embodiment: a slot is provided on one side of the dust collection box 61, and a dust discharge box 66 is inserted into the slot. A sealing strip is provided on the contact surface between the dust discharge box 66 and the slot.

[0037] It should be noted that the dust collection box 66 is used to collect dust from the dust collection box 61. When the dust collection box 66 is full, it can be easily pulled out from the insertion slot for cleaning. The sealing strip ensures the seal between the dust collection box 66 and the dust collection box 61, preventing dust leakage. Working principle: When using this utility model, firstly, the steel purlin is placed into the surface of the two sets of L-shaped clamping plates 45 in the fixing mechanism 4 inside the protective shell 2 through the inlet and outlet 3. Then, the fixing motor 43 is started, which drives the bidirectional threaded rod 42 to rotate. Since the threads at both ends of the bidirectional threaded rod 42 are opposite, the sliding protrusion 44 installed on it will move in opposite directions under the action of the threads. The limiting rod 47 and the sliding groove 46 limit the sliding protrusion 44 to ensure its linear movement. When the sliding protrusion 44 moves, it drives the L-shaped clamping plate 45 connected to it to move closer to the middle, thereby fixing the steel purlin tightly between the two sets of L-shaped clamping plates 45 to prevent it from shaking during the polishing process. The rotating motor 573 operates, driving the rotating plate 51 to rotate under the support of the turntable bearing 572, thereby driving the cross slide 52 and polishing assembly mounted on the rotating plate 51 to rotate as a whole, realizing flexible adjustment of the polishing angle to meet the polishing requirements of steel purlins of different shapes. By controlling the moving end of the cross slide 52, the mounting plate 53 is precisely moved in the horizontal and vertical directions, thereby accurately moving the polishing motor 55 and polishing disc 56 to the position of the steel purlin that needs to be polished. The polishing motor 55 starts, driving the polishing disc 56 to rotate at high speed through the rotating shaft 54 ​​to polish the end of the steel purlin, removing burrs, oxide layers, etc. on the surface, so that the surface of the steel purlin reaches the required flatness and smoothness. At the same time, the vacuum blower 64 starts, generating a strong negative pressure inside the suction housing 63. The dust and debris generated during the polishing of the steel purlins are collected by the dust hood 62. Under the action of negative pressure, the dust and debris enter the suction housing 63 through the dust hood 62 and are then filtered by the filter screen 65. The dust and debris are intercepted in the dust collection box 61, while clean air is discharged through the air outlet of the vacuum blower 64. When the dust in the dust collection box 61 accumulates to a certain level, the operator can remove the dust discharge box 66 from the insertion slot, clean the dust, and then reinstall it.

[0038] The control method of the fixed motor, cross slide, polishing motor, rotating motor and dust extraction fan in this application is to automatically control them through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, this application is mainly used to protect the structure, shape and their combination, so the control method and circuit connection will not be explained in detail in this application.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
