[0032] At present, the traditional manual grinding operation of U-rib grooves has long had many technical pain points. For example, it takes 60 minutes to manually grind a single 10-meter U-rib groove, and two people must work together, which is costly. In addition, key parameters such as grinding depth and groove angle rely on workers' experience and judgment, resulting in a product qualification rate of less than 80%, affecting the quality of steel structure welding.

[0033] Based on this, an embodiment of the present disclosure provides an automatic grinding device for U-rib bidirectional grooves, comprising a frame, a conveying mechanism and a grinding mechanism, wherein the conveying mechanism is arranged on the frame, and the grinding mechanism is arranged at one end of the extension direction of the frame, the conveying mechanism comprises at least one active roller and multiple driven rollers to convey the U-rib for grinding, and at least one of the active rollers is arranged on the side of the frame close to the grinding mechanism to enhance the transmission power of the grinding area and prevent the U-rib from sliding and deviating during the grinding process; the grinding mechanism comprises an installation frame, an adjustment mechanism and multiple grinding parts, the grinding parts are connected to the installation frame through the adjustment mechanism, and multiple grinding parts are arranged relative to each other, and the adjustment mechanism is used to adjust the position of the grinding end of the grinding part relative to the distance in the width direction and the height direction of the U-rib, thereby enhancing the adaptability to the grinding of various U-rib models.

[0034] The following describes the U-rib bidirectional groove automatic grinding device in detail through a specific embodiment:

[0035] Reference Figures 1 to 6 As shown, the present disclosure provides an automatic grinding device for U-rib bidirectional grooves, including a frame 1, a conveying mechanism 2 and a grinding mechanism 3, the conveying mechanism 2 is arranged on the frame 1, and the grinding mechanism 3 is arranged at one end of the extension direction of the frame 1, wherein the conveying mechanism 2 includes at least one active roller 21 and multiple driven rollers 22, and at least one active roller 21 is arranged on the side of the frame 1 close to the grinding mechanism 3; the grinding mechanism 3 includes a mounting frame 31, an adjusting mechanism 32 and multiple grinding pieces 33, the grinding pieces 33 are connected to the mounting frame 31 through the adjusting mechanism 32, and the multiple grinding pieces 33 are arranged relatively to each other, and the adjusting mechanism 32 is used to adjust the position of the grinding end of the grinding piece 33 relative to the distance in the width direction and the height direction of the U rib.

[0036] The frame 1 disclosed in the present invention is used to install a conveying mechanism 2 and / or a grinding mechanism 3, wherein the grinding mechanism 3 is arranged at one end of the extension direction of the frame 1. The grinding mechanism 3 can be directly connected to the frame 1, or can be arranged at one end of the extension direction of the frame 1 through an independent mounting frame. The conveying mechanism 2 disclosed in the present invention includes at least one active roller 21 and multiple driven rollers 22, and at least one active roller 21 is arranged on the side of the frame 1 close to the grinding mechanism 3, so as to enhance the transmission power of the grinding area and avoid the U-rib from sliding and offsetting during the grinding process. The number of the two active rollers 21 can be set to multiple, and the multiple active rollers 21 and the driven rollers 22 can be alternately arranged in the extension direction of the frame 1, or the multiple active rollers 21 can be arranged in a concentrated manner.

[0037] The polishing mechanism 3 disclosed herein includes a mounting frame 31, an adjustment mechanism 32, and a plurality of polishing members 33. The polishing members 33 include a high-speed motor and a bowl-shaped steel ball. The polishing members 33 are connected to the mounting frame 31 via the adjustment mechanism 32, and the plurality of polishing members 33 are arranged relative to each other. The adjustment mechanism 32 is used to adjust the position of the polishing end of the polishing member 33 relative to the distance in the width direction and the height direction of the U-rib. Specifically, the plurality of polishing members 33 are arranged relative to each other to achieve simultaneous polishing of the grooves on both sides of the U-rib. The number of polishing members 33 can be set to an even number, such as two or four, and the number of polishing members 33 arranged relative to each other is set to be equal to ensure balanced polishing parameters on both sides of the U-rib. The adjustment mechanism 32 is used to adjust the position of the polishing end of the polishing member 33 relative to the distance in the width direction and the height direction of the U-rib. The distance adjustment in the width direction can adapt to the width of different models of U-ribs, and the position adjustment in the height direction of the U-rib can accurately adjust the polishing position of the U-rib, realizing multi-degree-of-freedom adjustment in the lateral and height directions to be compatible with various specifications of U-ribs. When in use, the U rib is placed on the conveying mechanism 2 of the frame 1, and the active roller 21 of the conveying mechanism 2 drives the U rib to move toward the grinding mechanism 3, wherein the grinding mechanism 3 adjusts the distance between the relatively set grinding parts 33 when selecting the U rib to be processed so that the U rib can be accurately ground on both sides of the groove when it is conveyed to the grinding area through the conveying mechanism 2. As the conveying mechanism gradually conveys the entire length of the U rib through the grinding area of ​​the grinding mechanism 3, the grinding of the grooves on both sides of the U rib is completed.

[0038] In some embodiments, a positioning mechanism is also included, which includes a limit member 41 and multiple positioning rollers 42. The multiple positioning rollers 42 and the limit member 41 are arranged on both sides of the extension direction of the frame 1, and the rolling surface of the positioning roller 42 and the abutment surface of the limit member 41 face the opposite sides of the U rib, wherein the limit member 41 includes a limit frame 411, an abutment 412 and a limit adjustment member 413. The limit frame 411 is connected to the frame 1, and the abutment 412 is connected to the limit frame 411 through the limit adjustment member 413. The limit adjustment member 413 is used to adjust the abutment force between the abutment 412 and the U rib.

[0039] In this embodiment, multiple positioning rollers 42 and stoppers 41 precisely position the U-rib during transport through multi-point positioning and clamping, ensuring a straightness error of 0.5 mm or less along the polishing path. A stop adjustment member 413 adjusts the contact force between the abutment member 412 and the U-rib to accommodate U-ribs of varying widths and prevent over-tightening or non-clamping.

[0040] In some embodiments, the abutment member 412 includes a ball 4121 and a mounting shell 4122, the ball 4121 and the mounting shell 4122 are rotatably connected, and the ball 4121 protrudes from the mounting shell 4122, and the portion of the ball 4121 protruding from the mounting shell 4122 faces the U-rib.

[0041] In this embodiment, the abutment member 412 includes a ball 4121 and a mounting shell 4122. This design uses the principle of rolling friction to significantly reduce motion resistance, while relying on the curved surface adaptive characteristics of the ball to achieve precise guiding function, ensuring that the special-shaped U-rib is smoothly transferred to the grinding station along the preset trajectory.

[0042] In some embodiments, the limit adjustment member 413 includes a threaded sleeve 4131 and a screw 4132. The threaded sleeve 4131 is connected to the limit frame 411. The screw 4132 is screwed into the threaded sleeve 4131. The abutment member 412 is arranged at the end of the screw 4132 facing the U rib.

[0043] In this embodiment, the abutment 412 is arranged at the end of the screw 4132 facing the U rib, and the other end of the screw 4132 is set as a knob. By turning the knob, the screw 4132 can be screwed in and out of the threaded sleeve 4131. The setting of the threaded sleeve 4131 and the screw 4132 is convenient for adjustment and the positioning effect after adjustment is good, and the failure rate of the equipment is low.

[0044] In some embodiments, the adjustment mechanism 32 includes a slide, a slider and a lifting platform. The lifting platform is connected to the mounting frame 31. The slide is arranged on the lifting platform, and the extension direction of the slide is perpendicular to the extension direction of the frame 1. The polishing piece 33 is slidably connected to the slide through the slider.

[0045] In this embodiment, the extension direction of the slide is perpendicular to the extension direction of the frame 1, so that the grinding end of the grinding piece 33 can be adjusted relative to the U rib through the slide and the slider to ensure that the grinding end fits the U rib to be ground. The lifting platform realizes the position adjustment of the grinding end of the grinding piece 33 in the height direction of the U rib, and can accurately adjust the grinding position of the U rib. Specifically, the lifting platform can be a scissor-type lifting platform, which adopts a multi-layer cross-bracket structure and is lifted and lowered by hydraulic or electric drive. The scissor-type lifting platform has strong stability and high load capacity; the guide rail lifting platform is vertically lifted and lowered along a preset track, and its repeat positioning accuracy is ±1mm, which is more conducive to precision grinding.

[0046] In some embodiments, the number of the frames 1 is multiple, and the polishing mechanism 3 is disposed between two frames 1 .

[0047] In this embodiment, the number of the frame 1 is set to be multiple, such as Figure 1 As shown, the present disclosure specifically sets up two frames, and the structures of multiple frames 1 are the same. When used in combination, the conveying direction of the conveying mechanism 2 needs to be adjusted to be the same. The U rib is conveyed to the grinding mechanism 3 on the first frame 1 for grinding, and the polished U rib segment enters the second frame 1, realizing stable transmission of the U rib before, during and after grinding, and further ensuring that the U rib maintains precise positioning during the grinding process, thereby improving the grinding quality.

[0048] In some embodiments, a dust removal mechanism 5 is also included, which includes a dust hood, a suction device and a dust box. The dust hood is arranged in the grinding range of the grinding mechanism 3, and the suction device is used to suck the grinding dust from the range of the dust hood into the dust box.

[0049] In this embodiment, a dust removal mechanism 5 is installed in the grinding area. Using a high-powered suction device, it promptly removes metal shavings generated during grinding, greatly ensuring worker safety. A sealed dust box is also provided to prevent metal shavings from splashing out, and a dust hood further prevents them from escaping the grinding area. All electronic controls are integrated into the control panel, enabling remote control of the grinder and minimizing the risk of direct damage to the human body from metal shavings and dust generated during grinding.

[0050] In some embodiments, the active roller 21 includes a variable frequency motor 211, a transmission chain 212, a transmission shaft 213 and a roller 214. The roller 214 is rotatably connected to the frame 1, the transmission shaft 213 is connected to the roller 214, and the variable frequency motor 211 is transmission-connected to the transmission shaft 213 through the transmission chain 212.

[0051] In this embodiment, the active roller uses a variable frequency motor 211 to drive roller 214 via a transmission chain 212 and a drive shaft 213, achieving precise speed regulation and high synchronization to accommodate varying feed speed requirements. A variable frequency motor can control speed with high position accuracy and convert voltage signals into torque and speed to drive the controlled object. The rotor speed of a variable frequency motor is controlled by an input signal and responds quickly. In automatic control systems, it serves as an actuator and features a small electromechanical time constant and high linearity. It converts the received electrical signal into an angular displacement or angular velocity output on the motor shaft.

[0052] In some embodiments, a frame lifting mechanism is further included, which is connected to the frame 1 and is used to adjust the height of the frame 1 relative to the load-bearing surface of the frame 1. In this embodiment, the frame lifting mechanism disclosed herein can be connected to the frame 1 using a hydraulic cylinder or an electric push rod to achieve height self-adaptation and adapt to different production lines or ground working conditions. Specifically, Figure 6 As shown, the frame 1 of the present disclosure is provided with a plurality of main support frames, with steel plates welded underneath and bolts mounted on the steel plates for adjusting the height of the tire frame to ensure that the tire frame is in a horizontal state or other required angle state.
