Description

Technical Field

[0001] This utility model relates to the field of steel structure processing technology, and in particular to a steel structure burr grinding device. Background Technology

[0002] In the field of steel structure processing, after the steel plate has been drilled, a large number of burrs are often generated on its edges and surface. These burrs not only affect the appearance quality of the steel structure components, but may also cause safety hazards during subsequent assembly, transportation and use, such as scratching operators or causing loose connections between components. Therefore, burr removal and grinding of steel structure components is a key step to ensure its processing quality.

[0003] Currently, most steel structure deburring devices on the market are fixed structures, and the spacing of their grinding mechanisms is usually fixed. Such fixed structures can only be used to grind steel plates of a single thickness or a narrow thickness range. When processing steel plates of different thicknesses, it is often necessary to change different grinding equipment or make complex mechanical adjustments to the device. This is not only cumbersome and time-consuming, but also seriously affects production efficiency and makes it difficult to meet diverse processing needs, resulting in a narrow range of applications.

[0004] Meanwhile, during the grinding process, due to the large friction between the grinding belt and the steel structure, if the steel structure is not effectively fixed, it is very easy for it to shift or jump during the conveying process, resulting in inaccurate grinding position, incomplete burr removal, or even over-grinding or missed grinding, which seriously affects the grinding accuracy and workpiece quality.

[0005] Furthermore, the existing clamping mechanisms are difficult to adapt flexibly to steel plates of different widths. Some devices use manual adjustment of the height of the clamping components, which has low adjustment accuracy and is inconvenient to operate. This cannot guarantee stable clamping of steel plates of different widths, further aggravating the instability during the grinding process and restricting the efficiency and quality improvement of steel structure grinding.

[0006] Therefore, how to provide a steel structure burr grinding device is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0007] One objective of this invention is to provide a steel structure burr grinding device. This invention utilizes a servo motor-driven lead screw and a movable frame to flexibly and precisely adjust the distance between the grinding mechanisms on both sides, thereby adapting to vertically placed steel structural components of different thicknesses. It enables continuous grinding of various workpieces without requiring equipment changes, significantly improving the device's applicability and flexibility. Simultaneously, the pressure roller driven by an electric push rod clamps and constrains the top of the steel structural component, effectively preventing it from shifting or jumping during grinding due to friction from the grinding belt. This ensures a stable and consistent grinding position, guarantees uniform burr removal and surface finishing accuracy, and achieves efficient and precise removal of burrs from both sides of the steel structural component, improving overall processing quality and production efficiency.

[0008] A steel structure burr grinding device according to an embodiment of the present invention includes a base, a conveyor belt, and a grinding mechanism. The conveyor belt is disposed at the bottom inner side of the base. Side plates are symmetrically installed on both sides of the top of the conveyor belt on the inner side of the base. Movable frames are symmetrically fixedly installed on the outer walls of the two sets of side plates, and the two sets of movable frames pass through both sides of the base. The grinding mechanism includes rollers that are longitudinally and vertically fixedly installed on both sides of the inner side of the side plates. A grinding belt is sleeved on the rollers. Supports are symmetrically fixedly installed on the outer walls of both sides of the base. A servo motor is fixedly installed on the outer side of the top of the support. A lead screw is driven and installed at the output end of the servo motor. A screw hole is centrally opened through the movable frame, and the lead screw passes through the screw hole to form a transmission pair.

[0009] Furthermore, a drive motor is fixedly installed on the outer wall of the side plate near the grinding belt via a motor frame. A large pulley is driven on the top of the drive motor, and a small pulley is driven on the top of the roller. The large pulley and the small pulley are connected by a belt drive.

[0010] Furthermore, electric push rods are fixedly installed at both ends of the outer walls on both sides of the base, and pressure roller brackets are fixedly installed on the top of the electric push rods. Several sets of pressure rollers are installed on the lower inner side of the pressure roller brackets.

[0011] Furthermore, the pressure rollers are made of rubber, and multiple sets of pressure rollers are equidistantly distributed within the pressure roller bracket, which is centrally located at the top of the conveyor belt.

[0012] Furthermore, the grinding belt is made of alumina sanding belt, and the grit size of the sanding belt is in the range of 80-240 mesh.

[0013] Furthermore, the conveyor belt is made of wear-resistant rubber material, and the conveyor belt is equipped with reinforcing ribs inside. The conveyor belt is driven by a geared motor installed on the side wall of the base.

[0014] Furthermore, the pressure roller is rotatably connected to the pressure roller bracket via a deep groove ball bearing, and the diameter of the pressure roller is 50-100mm.

[0015] The beneficial effects of this utility model are: In this invention, the servo motor drives the lead screw and the movable frame to precisely adjust the distance between the two grinding mechanisms, adapting to the grinding needs of steel plates of different thicknesses. It can process various workpieces without changing equipment, significantly improving the applicability and flexibility of the device. The rubber pressure rollers located at the top of the conveyor belt are height-adjustable via an electric push rod, reliably pressing the steel structural components and preventing them from shifting or jumping during grinding due to friction from the grinding belt. This ensures a stable and consistent grinding position. Furthermore, the rubber pressure rollers can be automatically adjusted in height via the electric push rod, making it suitable for use with steel plates of different widths.

[0018] To make the technical means and objectives and effects of this utility model easier to understand, the embodiments of this utility model will be described in detail below with reference to specific figures.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0022] like Figure 1-4 As shown, this utility model discloses a steel structure burr grinding device, including a base 1, a conveyor belt 2, and a grinding mechanism. The conveyor belt 2 is disposed at the bottom inner side of the base 1. Side plates 3 are symmetrically installed on both sides of the top of the conveyor belt 2 on the inner side of the base 1. Movable frames 6 are symmetrically fixedly installed on the outer walls of the two sets of side plates 3, and the two sets of movable frames 6 pass through both sides of the base 1. The grinding mechanism includes rollers 18 that are longitudinally and vertically fixedly installed on both sides of the inner side of the side plates 3. A grinding belt 4 is sleeved on the rollers 18. Supports 7 are symmetrically fixedly installed on the outer walls of both sides of the base 1. A servo motor 8 is fixedly installed on the outer side of the top of the support 7. A lead screw 9 is driven and installed at the output end of the servo motor 8. A screw hole 17 is centrally opened through the movable frame 6, and the lead screw 9 passes through the screw hole 17 to form a transmission pair.

[0023] The steel structure deburring device disclosed in this application involves placing the steel structure to be deburred vertically on a conveyor belt 2 during operation. The continuous transport of the steel structure is achieved through the operation of the conveyor belt 2. Based on the thickness of the steel structure, the servo motors 8 on both sides of the base 1 are activated. The servo motors 8 drive the lead screw 9 to rotate. Since the lead screw 9 and the screw hole 17 of the movable frame 6 form a transmission pair, the rotational motion of the lead screw 9 is converted into the horizontal movement of the movable frame 6. This, in turn, drives the side plates 3 on both sides and the deburring mechanism mounted on the side plates 3 to move synchronously until the deburring belts 4 on both sides contact the side walls of the steel structure and achieve appropriate deburring pressure.

[0024] During grinding, the drive motor 5 on the outer wall of the side plate 3 starts, and the drive motor 5 drives the large pulley 15 to rotate. The large pulley 15 drives the small pulley 14 on the top of the roller 18 to rotate through the belt 16, which in turn drives the roller 18 and the grinding belt 4 sleeved on the roller 18 to rotate at high speed. The rotating grinding belt 4 continuously grinds the burrs on both sides of the steel structure conveyed on the conveyor belt 2, achieving efficient removal of burrs.

[0025] To prevent the steel structure from shifting or jumping during the grinding process due to the friction of the grinding belt 4, the electric push rods 10 at the front and rear ends of the outer walls on both sides of the base 1 are activated. The electric push rods 10 push the pressure roller bracket 11 downward, so that the pressure roller 12 on the inner side of the pressure roller bracket 11 presses against the top of the steel structure. Through the rolling constraint of the pressure roller 12, the stability of the steel structure during the conveying and grinding process is ensured, and the grinding accuracy is guaranteed.

[0026] The steel structure burr grinding device described in this application, through the cooperation of servo motor 8, lead screw 9 and movable frame 6, can flexibly adjust the spacing of grinding belts 4 on both sides to adapt to the grinding needs of steel structural parts of different widths and specifications, and has strong versatility; at the same time, the setting of pressure roller 12 effectively ensures the stable conveying of steel structural parts, and combined with the high-speed operation of grinding belt 4, realizes continuous and efficient burr grinding, and improves the processing quality and production efficiency of steel structural parts.

[0027] As a preferred example of this application, the pressure rollers 12 are made of rubber, and multiple sets of pressure rollers 12 are equidistantly distributed within the pressure roller bracket 11, which is centrally located at the top of the conveyor belt 2. The rubber pressure rollers 12 possess good elasticity and friction, reliably pressing the steel structural components while avoiding hard damage to their surface. The multiple equidistantly distributed pressure rollers 12 can evenly distribute pressure, further enhancing the stability of the steel structural components.

[0028] As a preferred example of this application, the grinding belt 4 is made of alumina abrasive belt, and the grit size range of the belt is 80-240 mesh. Alumina abrasive belt has high hardness and wear resistance, making it suitable for burr removal from hard materials such as steel structures; the grit size range of 80-240 mesh can be flexibly selected according to the size of the burr and the grinding precision requirements. A coarse grit of about 80 mesh can quickly remove large burrs, while a fine grit of about 240 mesh can achieve fine surface grinding, meeting different processing needs.

[0029] As a preferred example of this application, the conveyor belt 2 is made of wear-resistant rubber material, and the conveyor belt 2 has internal reinforcing ribs. The conveyor belt 2 is driven by a geared motor 13 installed on the side wall of the base 1. The wear-resistant rubber material improves the service life of the conveyor belt 2, and the internal reinforcing ribs enhance the load-bearing capacity of the conveyor belt 2, making it suitable for conveying heavier steel structural components. The geared motor 13 ensures that the conveying speed of the conveyor belt 2 is stable and controllable, which facilitates matching with the grinding rhythm of the grinding belt 4 and ensures a uniform grinding effect.

[0030] As a preferred example of this application, the pressure roller 12 is rotatably connected to the pressure roller bracket 11 via a deep groove ball bearing, and the diameter of the pressure roller 12 is 50-100mm. The deep groove ball bearing makes the rotation of the pressure roller 12 more flexible and smooth, reduces the frictional resistance between the pressure roller 12 and the steel structural component, and avoids obstructing the conveying of the steel structural component; the 50-100mm diameter design, while ensuring the pressing effect, reduces the number of contacts between the pressure roller 12 and the steel structural component, and reduces the risk of wear on the surface of the steel structural component.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
