Description

Technical Field

[0001] This utility model relates to the field of precision steel processing technology, specifically to a precision steel grinding equipment. Background Technology

[0002] Precision steel is a special type of steel characterized by high-precision dimensional control, excellent mechanical properties, and superior surface quality. It is widely used in fields with extremely stringent requirements for structural strength and appearance, such as building curtain walls, high-end equipment manufacturing, and precision engineering components. Its manufacturing process involves connecting multiple steel plates using precision welding technology to form regular rectangular steel components. However, weld seams inevitably form at the weld joints between the steel plates. These weld seams not only affect the overall aesthetics of the steel but can also become potential stress concentration points. Therefore, meticulous grinding of the weld seams is essential to eliminate defects, improve surface smoothness, and ensure structural safety. The grinding process for precision steel... In grinding operations, specialized grinding machines are indispensable tools. These grinding machines are typically designed with multiple drive wheels, which drive the grinding belt to contact the weld at high speed, thereby achieving fine grinding of the weld. However, during operation, because the grinding belt is constantly in a state of high motion and generates friction with the weld surface, and is also affected by uneven tension transmitted by the drive wheels and changes in contact pressure caused by small protrusions or depressions on the steel surface, the grinding belt is prone to deviation. This deviation not only leads to uneven grinding areas, affecting the grinding quality and appearance of the refined steel, but may also accelerate the wear of the grinding belt, shorten its service life, and increase production costs. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a precision steel grinding device with advantages such as belt deviation correction, thus solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a fine steel grinding device, comprising a feeding rack and a traveling frame, wherein the traveling frame and the feeding rack are connected by a linear drive mechanism;

[0005] The feeding rack has a bearing plate inside. An F-shaped support frame is fixedly connected to the side of the bearing plate. A swing plate is hinged to one side of the top of the support frame. An adjusting plate is rotatably connected to the side of the swing plate via a rotating shaft. The bottom of the adjusting plate is fixedly connected to the swing plate via a return spring. An adjusting screw is threadedly connected to the side of the swing plate away from the adjusting plate. One end of the adjusting screw contacts the swing plate. A pneumatic spring is connected between one side of the support frame and the swing plate. A tensioning wheel is rotatably connected to the side of the swing plate away from the adjusting screw via a rotating shaft. The circumference of the tensioning wheel is arc-shaped.

[0006] The bottom end of the support frame is rotatably connected to a pulley one, the side of the bearing plate is fixedly mounted with a pulley motor, the output shaft of the pulley motor is fixedly connected to a pulley two, and a sanding belt is connected between pulley one, pulley two and tensioning wheel for transmission.

[0007] The traveling frame is equipped with a vertical adjustment mechanism for driving the bearing plate to make vertical movements;

[0008] The inner wall of the frame is equipped with a lateral adjustment mechanism for driving the vertical drive mechanism to move along the width of the traveling frame.

[0009] Furthermore, the linear drive mechanism includes a toothed plate fixedly connected to the upper surface of one side of the feeding rack along its width direction, a linear drive motor fixedly installed on one side of the traveling frame corresponding to the toothed plate, a rotating column fixedly connected to the output shaft of the linear drive motor, and a gear meshing with the toothed plate fixedly connected to the circumferential surface of the rotating column.

[0010] With the above scheme, when the linear drive motor is working, it drives the rotating column and gear to rotate. Since the gear meshes with the toothed plate, the traveling frame moves in a straight line relative to the feeding rack, thereby realizing the position adjustment of the grinding device in the length direction of the feeding rack.

[0011] Furthermore, the linear drive mechanism also includes two guide rods fixedly connected to the upper surface of the feeding rack, and two sets of guide slides that are slidably sleeved with the corresponding guide rods are fixedly connected to the bottom end of the traveling frame.

[0012] Through the above scheme, the cooperation between the guide rod and the guide slide provides guidance for the linear movement of the traveling frame, ensuring that the traveling frame remains stable during movement.

[0013] Furthermore, the vertical adjustment mechanism includes a support plate, and a lead screw is rotatably connected to one side of the support plate corresponding to the bearing plate through a bearing seat. The threaded end of the lead screw is threadedly connected to a threaded seat that is fixedly connected to the support plate. A vertical adjustment motor is fixedly connected to the side of the support plate, and the output end of the vertical adjustment motor is fixedly connected to one end of the lead screw.

[0014] With the above scheme, after the vertical adjustment motor is started, it drives the lead screw to rotate. Since the lead screw is threadedly connected to the threaded seat and the threaded seat is fixed to the support plate, the rotational motion of the lead screw is converted into the linear motion of the bearing plate, thereby realizing the vertical position adjustment of the bearing plate.

[0015] Furthermore, the vertical adjustment mechanism also includes two slide rails fixedly connected to one side of the support plate corresponding to the bearing plate, and the bearing plate is slidably connected to the two slide rails along the length direction of the two slide rails.

[0016] Through the above scheme, the slide rail provides guidance for the vertical movement of the support plate, ensuring that the support plate will not shake or deviate during the movement.

[0017] Furthermore, the vertical adjustment mechanism also includes two proximity sensors fixedly installed on the side of the support plate. A baffle is fixedly connected to the side of the support plate corresponding to the two proximity sensors. The baffle is located between the two proximity sensors. One proximity sensor is used to monitor the upper travel of the support plate, and the other proximity sensor monitors the lower travel of the support plate.

[0018] With the above scheme, when the support plate moves vertically, the baffle moves with the support plate. When the baffle approaches the upper travel proximity sensor, it indicates that the support plate has reached the upper limit position; when the baffle approaches the lower travel proximity sensor, it indicates that the support plate has reached the lower limit position. The signal can be fed back to the external control equipment to control the vertical adjustment mechanism to stop working. The travel of the support plate can be controlled by the proximity sensor to prevent it from exceeding the safe movement range.

[0019] Furthermore, the lateral adjustment mechanism includes a second lead screw rotatably connected to the inner wall of the traveling frame via a bearing seat, a second threaded seat fixedly connected to the side of the support plate away from the bearing plate, the second threaded seat being threadedly connected to the second lead screw, and a rotating handle fixedly connected to one end of the second lead screw.

[0020] The above scheme involves rotating the handle to drive the second lead screw to rotate. Since the second lead screw is threadedly connected to the second threaded seat, the rotational motion of the second lead screw is converted into the horizontal linear motion of the support plate and the entire vertical adjustment mechanism and grinding device, thereby achieving the adjustment of the grinding device's position in the horizontal direction.

[0021] Furthermore, the lateral adjustment mechanism also includes two slide rails fixedly connected to the inner wall of the traveling frame, and the support plate is slidably connected to the two slide rails along the width direction of the placement frame.

[0022] Through the above scheme, the slide rail 2 provides guidance for the lateral movement of the support plate, ensuring that the support plate moves smoothly during lateral adjustment.

[0023] Furthermore, a protective plate to prevent sparks from splashing is fixedly connected to one side of the support frame, and the sand belt is located inside the protective plate.

[0024] The above solution can prevent sparks and debris from flying everywhere during the grinding process.

[0025] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0026] This precision steel grinding equipment, through the combined action of an F-shaped support frame, a swing plate, an adjusting plate, an adjusting screw, and a return spring, can slightly adjust the tilt angle of the tension wheel when the adjusting screw is rotated. This allows for a precise lateral corrective force to be applied to the running sanding belt, effectively overcoming belt deviation caused by uneven force, wear, or installation errors. Its arc-shaped tension wheel design changes the contact between the sanding belt and the wheel surface from line contact to surface contact, significantly increasing the contact area and friction, ensuring a more uniform correction force, further increasing the contact area and correction force, and guaranteeing that the sanding belt always runs stably on the set trajectory.

[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] Please see Figures 1-7 The fine steel grinding equipment in this embodiment includes a feeding rack 1 and a traveling frame 2, which are connected by a linear drive mechanism 3.

[0046] The material feeding rack 1 has a bearing plate 4 inside. An F-shaped support frame 5 is fixedly connected to the side of the bearing plate 4. A swing plate 6 is hinged to one side of the top of the support frame 5. An adjusting plate 7 is rotatably connected to the side of the swing plate 6 via a rotating shaft. The bottom end of the adjusting plate 7 is fixedly connected to the swing plate 6 via a return spring 8. An adjusting screw 9 is threadedly connected to the side of the swing plate 6 away from the adjusting plate 7. One end of the adjusting screw 9 contacts the swing plate 6. A pneumatic spring 10 is connected between one side of the support frame 5 and the swing plate 6. A tensioning wheel 11 is rotatably connected to the side of the swing plate 6 away from the adjusting screw 9 via a rotating shaft. The circumference of the tensioning wheel 11 is arc-shaped. This arc design allows for better contact with the sanding belt 15, making the sanding belt 15 more evenly stressed during transmission and reducing sanding belt stress. To prevent the sanding belt 15 from deviating, the adjusting screw 9 is rotated so that its end pushes against the adjusting plate 7, forcing the adjusting plate 7 to rotate around the axis connecting it to the swing plate 6. This overcomes the elastic force of the return spring 8 and moves one end of the adjusting plate 7 away from the swing plate 6. This action is transmitted to the swing plate 6, which in turn causes the tension wheel 11 to deflect and tilt. The tilt of the tension wheel 11 applies a lateral corrective force to the running sanding belt 15, thereby correcting the deviation of the sanding belt 15. The pneumatic spring 10 provides a constant and buffered support torque to the swing plate 6, ensuring that the tension wheel 11 always presses against the sanding belt 15 with a stable pressure. This ensures that the sanding belt 15 maintains a constant tension under various working conditions, effectively preventing the sanding belt 15 from slipping, shaking, or loosening.

[0047] The bottom end of the support frame 5 is rotatably connected to a pulley 12, and a pulley motor 13 is fixedly installed on the side of the bearing plate 4. The output shaft of the pulley motor 13 is fixedly connected to a pulley 14. A sanding belt 15 is connected between the pulley 12, the pulley 14, and the tension wheel 11. The pulley motor 13 drives the pulley 14 to rotate, thereby driving the sanding belt 15 to circulate between the pulley 12, the pulley 14, and the tension wheel 11 to achieve the grinding operation of fine steel.

[0048] The travel frame 2 is equipped with a vertical adjustment mechanism 16 for driving the bearing plate 4 to move vertically. The vertical adjustment mechanism 16 is set up to make it easy to accurately adjust the height of the bearing plate 4 according to the thickness of the fine steel and the grinding requirements, thereby controlling the contact pressure between the sanding belt 15 and the fine steel.

[0049] The inner wall of the frame is provided with a lateral adjustment mechanism 17 for driving the vertical drive mechanism to move along the width direction of the traveling frame 2. The lateral adjustment mechanism 17 enables the entire grinding device to be adjusted in the lateral direction to meet the grinding requirements of welds at different positions of the fine steel.

[0050] The linear drive mechanism 3 includes a toothed plate 301 fixedly connected to the upper surface of one side of the feeding rack 1 along its width direction. A linear drive motor 302 is fixedly installed on one side of the traveling frame 2 corresponding to the toothed plate 301. A rotating column 303 is fixedly connected to the output shaft of the linear drive motor 302. A gear 304 that meshes with the toothed plate 301 is fixedly connected to the circumferential surface of the rotating column 303. When the linear drive motor 302 is working, it drives the rotating column 303 and the gear 304 to rotate. Since the gear 304 meshes with the toothed plate 301, the traveling frame 2 moves linearly relative to the feeding rack 1, thereby realizing the position adjustment of the grinding device in the length direction of the feeding rack 1. The linear drive mechanism 3 also includes two guide rods 305 fixedly connected to the upper surface of the feeding rack 1. Two sets of guide slides 306 that are slidably sleeved with the corresponding guide rods 305 are fixedly connected to the bottom end of the traveling frame 2. The cooperation between the guide rods 305 and the guide slides 306 provides guidance for the linear movement of the traveling frame 2, ensuring that the traveling frame 2 remains stable during movement.

[0051] The vertical adjustment mechanism 16 includes a support plate 1601. A lead screw 1602 is rotatably connected to one side of the support plate 1601 corresponding to the bearing plate 4 via a bearing seat. The threaded end of the lead screw 1602 is threadedly connected to a threaded seat 1603 fixedly connected to the support plate 1601. A vertical adjustment motor 1604 is fixedly connected to the side of the support plate 1601. The output end of the vertical adjustment motor 1604 is fixedly connected to one end of the lead screw. After the vertical adjustment motor 1604 starts, it drives the lead screw 1602 to rotate. Because the lead screw 1602 is threadedly connected to the threaded seat 1603… The threaded seat 1603 is fixed to the support plate 1601, thereby converting the rotational motion of the lead screw 1602 into the linear motion of the bearing plate 4, realizing the vertical position adjustment of the bearing plate 4. The vertical adjustment mechanism 16 also includes two slide rails 1605 fixedly connected to the support plate 1601 on one side of the bearing plate 4. The bearing plate 4 is slidably connected to the two slide rails 1605 along the length of the two slide rails 1605. The slide rails 1605 provide guidance for the vertical movement of the bearing plate 4, ensuring that the bearing plate 4 will not shake or deviate during the movement.

[0052] The vertical adjustment mechanism 16 also includes two proximity sensors 1606 fixedly mounted on the side of the support plate 1601. A baffle 1607 is fixedly connected to the side of the support plate 4 corresponding to the two proximity sensors 1606, located between the two proximity sensors 1606. One proximity sensor 1606 monitors the upper travel of the support plate 4, and the other proximity sensor 1606 monitors the lower travel of the support plate 4. When the support plate 4 moves vertically, the baffle 1607 moves with it. When the baffle 1607 approaches the upper travel proximity sensor 1606, it indicates that the support plate 4 has reached its upper limit position; when the baffle 1607 approaches the lower travel proximity sensor 1606, it indicates that the support plate 4 has reached its lower limit position. This signal can be fed back to an external control device to stop the vertical adjustment mechanism 16. The proximity sensors 1606 can control the travel of the support plate 4, preventing it from exceeding its safe range of motion. The lateral adjustment mechanism 17... The system includes a second lead screw 1701 rotatably connected to the inner wall of the traveling frame 2 via a bearing seat. A second threaded seat 1702 is fixedly connected to the side of the support plate 1601 opposite to the bearing plate 4. The second threaded seat 1702 is threadedly connected to the second lead screw 1701. A rotating handle 1703 is fixedly connected to one end of the second lead screw 1701. By rotating the rotating handle 1703, the second lead screw 1701 is driven to rotate. Since the second lead screw 1701 is threadedly connected to the second threaded seat 1702, the rotation of the second lead screw 1701 is thus controlled. The motion is transformed into the horizontal linear motion of the support plate 1601, the entire vertical adjustment mechanism 16, and the grinding device, thereby realizing the adjustment of the position of the grinding device in the horizontal direction. The horizontal adjustment mechanism 17 also includes two slide rails 1704 fixedly connected to the inner wall of the traveling frame 2. The support plate 1601 is slidably connected to the two slide rails 1704 along the width direction of the placement frame. The slide rails 1704 provide guidance for the horizontal movement of the support plate 1601, ensuring that the support plate 1601 moves smoothly during the horizontal adjustment process.

[0053] A protective plate 18 to prevent sparks from splashing is fixedly connected to one side of the support frame 5. The sanding belt 15 is located inside the protective plate 18. The protective plate 18 can block the sparks and debris generated during the grinding process from splashing everywhere.

[0054] The working principle of the above embodiment is as follows: First, when grinding the fine steel, the operator rotates the handle 1703, causing the lead screw 1701 and the threaded seat 1702 to drive the support plate 1601 to slide along the slide rail 1704, thereby adjusting the position of the sanding belt 15. Subsequently, the vertical adjustment motor 1604 drives the lead screw 1602 to rotate, and through the engagement of the lead screw 1602 and the threaded seat 1603, drives the bearing plate 4 to move vertically downward, so that the sanding belt 15 contacts the fine steel. After contact, the pulley motor 13 drives the corresponding pulley 14 to rotate. Through the transmission of the pulley 12, the pulley 14 and the tensioning wheel 11, the sanding belt 15 is driven to reciprocate and grind the weld seam of the fine steel. Then, the linear drive motor 302 can drive the rotating column 303 to rotate, so that the rotating column 303 can drive the gear 304 to mesh with the toothed plate 301, thereby driving the traveling frame 2 to move linearly along the length direction of the feeding rack 1, and grinding the fine steel during the movement.

[0055] When the sanding belt 15 deviates during its movement, the linear drive mechanism 3 stops working. Then, the operator rotates the adjusting screw 9 so that the end of the adjusting screw 9 contacts the adjusting plate 7, thereby causing the adjusting plate 7 to rotate around the axis and compress the reset spring 8. This allows the adjusting plate 7 to tilt the tension wheel 11, thus correcting the deviation of the sanding belt (15). When the pulley motor 13 starts working again, the guiding friction generated by the arc contour of the tension wheel 11 automatically guides the sanding belt 15 back to the preset center position, thereby achieving rapid and effective correction of the deviation of the sanding belt 15.
