Technical Field
[0001] This invention relates to the field of steel structure grinding, and specifically to a grinding device and method for the welding parts of a steel structure sphere. Background Technology
[0002] During the assembly of steel structure space frames, the welded joints between the steel structure and the tubular body need to be ground to smooth the spherical surface of the steel structure. However, current grinding methods rely on manual rotation using angle grinders, which is inefficient. Furthermore, most angle grinders use grinding discs, which can only grind within a circular area and are unsuitable for the welded joints of the tubular body. This results in incomplete grinding and easy displacement of the grinding position, affecting construction efficiency and the quality of the finished product. Therefore, measures are needed to address the problems of incomplete grinding and easy displacement of the grinding position. Summary of the Invention
[0003] The purpose of this invention is to overcome the defects of the prior art and provide a grinding device and method for the welding parts of a steel structure sphere, solving the problems of incomplete grinding areas and easy displacement of the grinding position during the grinding process.
[0004] The technical solution to achieve the above objective is: a grinding device and grinding method for the welded parts of a steel structure sphere, comprising: drive; A connecting bracket is attached to the end of the driver, and the driver drives the connecting bracket to rotate. An arc-shaped rod with one end hinged to the connecting frame; The grinding end, connected to the other end of the arc-shaped rod, is used to grind the welded parts of the steel structure sphere.
[0005] A further improvement of the technical solution of the present invention is that: an adjusting member is connected between the connecting frame and the arc-shaped rod, the adjusting member is connected to the middle part of the arc-shaped rod, and the adjusting member applies a force to the arc-shaped rod so that the end of the arc-shaped rod connected to the grinding end rotates away from the connecting frame.
[0006] A further improvement of the technical solution of the present invention is that: the adjusting member includes a plurality of springs, a plate connected to the bottom of the plurality of springs, and a second connecting rod connected to the end of the plate away from the springs, the second connecting rod being hinged to the middle section of the arc-shaped rod.
[0007] A further improvement of the technical solution of the present invention is that the flat plate is arranged in a triangular shape.
[0008] A further improvement of the technical solution of the present invention is that the second connecting rod is connected to the corner of the plate.
[0009] A further improvement of the technical solution of the present invention is that the grinding end is hinged to the arc-shaped rod so that the grinding end can be adjusted in angle.
[0010] A further improvement of the technical solution of the present invention is that: there are multiple arc-shaped rods, which are arranged at intervals along the circumference.
[0011] A further improvement of the technical solution of the present invention is that: the connecting frame includes a connecting seat and a first connecting rod connected to the bottom of the connecting seat; The connector is connected to the driver.
[0012] A grinding method for a steel structure sphere welding area grinding device includes the following steps: The grinding apparatus of claim 1 is provided, wherein the driver of the grinding apparatus is held and the grinding end is abutted against the welded part of the steel structure sphere to be ground; The driver of the grinding device is pressed down to rotate the arc-shaped rod around the hinge with the connecting frame, and the distance between the grinding end and the rotation axis of the driver is adapted to the radius of the welding part to be ground, so that the rotation axis of the driver is aligned with the center of the welding part to be ground. The driver is activated to drive the connecting frame and the arc-shaped rod to rotate, thereby causing the grinding end to rotate around the rotation axis of the driver to grind the welded part.
[0013] A further improvement of the technical solution of the present invention is that the provided grinding device further includes an adjusting member between the arc-shaped rod and the connecting frame, the adjusting member applying a force to the arc-shaped rod to rotate it away from the connecting frame; When the driver of the grinding device is pressed down, the connecting frame moves downward, causing the arc-shaped rod to rotate and be adjusted by the reverse force of the steel structure ball to be ground. At the same time, the arc-shaped rod is also subjected to the force applied by the adjusting component. The force applied by the adjusting component can balance the reverse force of the steel structure ball to be ground so that the arc-shaped rod remains stable.
[0014] By utilizing the above technical solution, the technical effects achieved by the present invention compared to the prior art are as follows: This invention provides a grinding device and method for the welding area of a steel structure sphere. By setting a movable node at the connection between the arc-shaped rod and the first connecting rod, the arc-shaped rod can move up and down along the first connecting rod. The other end of the arc-shaped rod can be adjusted in angle, thereby adjusting the grinding area. When the connecting frame drives the arc-shaped rod to rotate, one rotation of the arc-shaped rod grinds one circle of the welding area, forming a weld joint that fits the annular shape of the tube body. By setting an adjusting component between the grinding mechanism and the connecting seat, the spring deformation applies a relative thrust to the arc-shaped rod, causing the other end of the arc-shaped rod to expand away from the actuator. This changes the grinding range according to the welding area. Furthermore, by using multiple arc-shaped rods in conjunction with the grinding end, after the actuator drives the connecting frame to rotate one circle, multiple rods simultaneously grind the welding area multiple times in the same circle, making the grinding area more comprehensive and effectively improving construction efficiency and quality.
[0015] By setting a movable shaft between the grinding end and the arc-shaped rod, the grinding end can maintain its position and fit against the welding part when the angle of the arc-shaped rod is adjusted during the pressure application process, thus achieving the effect that the grinding surface always fits against the welding part.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0023] This invention provides a grinding device and method for the welded parts of a steel structure sphere. This device allows for angle changes by using an adjusting element between the grinding mechanism and the connecting seat, leveraging the effect of spring deformation to adjust the grinding range according to the welded part. The grinding device and method for the welded parts of a steel structure sphere are described below.
[0024] See Figure 1 The image shows a side view of a grinding device and method for the welded parts of a steel structure sphere according to the present invention. The following is in conjunction with... Figures 1 to 5 The structure of the grinding device and grinding method for the welded part of the steel structure sphere of the present invention will be described.
[0025] See Figure 1 , Figure 5 The present invention provides a grinding device for the welded part of a steel structure sphere, comprising: a connecting frame, a driver 2, an arc rod 7, and a grinding end 9. The connecting frame is connected to the end of the driver 2, and the driver 2 drives the connecting frame to rotate. One end of the arc rod 7 is hinged to the connecting frame, and the grinding end 9 is connected to the other end of the arc rod 7 for grinding the welded part A of the steel structure sphere.
[0026] Better, such as Figure 1 , Figure 5 As shown, by connecting the connecting frame to the end of the driver 2, the driver 2 drives the connecting frame to rotate, and the arc rod 7 is connected to the connecting frame and rotates with the connecting frame, so that the arc rod 7 drives the grinding end 9 at the bottom to grind the welding part A. The grinding position can be adjusted according to the welding part, and by applying downward pressure to the connecting frame, the adjusting part can be retracted to drive the grinding mechanism below the connecting frame to adjust the angle. The driver 2 drives the connecting frame to rotate, so that the grinding mechanism grinds the corresponding welding part A.
[0027] Furthermore, during the grinding process of welded part A, pressure is continuously applied to the connecting frame to achieve the effect of changing the grinding range back and forth. In use, the grinding range can be continuously adjusted by the amount of force applied by the personnel to meet the circular grinding requirements of the welded ball.
[0028] See Figures 1 to 4In one specific embodiment of the present invention, an adjusting member is connected between the connecting frame and the arc-shaped rod 7. The adjusting member is connected to the middle part of the arc-shaped rod 7. The adjusting member applies a force to the arc-shaped rod 7 so that the end of the arc-shaped rod 7 connected to the grinding end 9 rotates away from the connecting frame. By applying pressure to the connecting frame, the connecting frame squeezes the adjusting member, thereby realizing that the adjusting member applies a relative thrust to the arc-shaped rod 7, so that the arc-shaped rod 7 expands outward with the driver 2 as the center. A movable shaft is hinged at the connection between the grinding end 9 and the arc-shaped rod 7. The movable shaft drives the grinding end to adjust the angle at the end of the arc-shaped rod 7. The adjusting member includes multiple springs 3, a plate 5 connected to the bottom of the multiple springs 3, and a second connecting rod 6 connected to the end of the plate 5 away from the springs 3. The second connecting rod 6 is hinged to the middle section of the corresponding arc-shaped rod 7.
[0029] Better, such as Figures 1 to 4 As shown, by connecting the connector 1 to the driver 2, when the driver 2 is started, the connector 1 is rotated, which causes the connector 1 to drive the grinding mechanism to grind the welded part A, which can effectively improve the grinding efficiency.
[0030] Furthermore, such as Figures 1 to 4 As shown, by setting an adjusting component between the arc-shaped rod 7 and the connecting frame, when pressure is applied to the connecting frame, the spring 3 will generate a relative pushing force on the plate 5, causing the plate 5 and the second connecting rod 6 to push the middle section of the arc-shaped rod 7. A movable node 8 is set at the intersection of the arc-shaped rod 7 and the first connecting rod 4, allowing the arc-shaped rod 7 to move and adjust on the connecting frame. The movable node 8 can be tightened by bolts, so that one end of the arc-shaped rod 7 can be fixed in position on the connecting frame. When no pressure is applied to the connecting seat 1, the ground end 9 at the bottom of the arc-shaped rod 7 is attached to... When pressure is applied to the connecting seat 1 at the welding point A, the arc-shaped rod 7 will be pushed downward by the spring, causing the plate 5 and the second connecting rod 6 to support the middle section of the arc-shaped rod 7. This allows the arc-shaped rod 7 to be kept within a fixed range when supported. The driver 2 drives the connecting seat 1 to rotate, so that the arc-shaped rod 7 and the grinding end 9 grind a ring-shaped area at the welding point A, so that the ground area can be adapted to the tubular connecting part. This allows the grinding area and range to be adjusted appropriately according to the welding point A.
[0031] Furthermore, the end of the arc-shaped rod 7 near the grinding end 9 is gradually narrowed, so that the grinding end 9 is not easily blocked by the end of the arc-shaped rod 7 during the movement, effectively improving the flexibility of angle adjustment.
[0032] See Figure 2 In one specific embodiment of the present invention, the plate 5 is arranged in a triangular shape, and the second connecting rod 6 is arranged at intervals.
[0033] Furthermore, such as Figure 2As shown, by placing multiple second links 6 at the bottom of the plate 5 near the corner, the distance between the multiple second links 6 can be evenly distributed, so that the area of the surface of the welded part A will not be more fully polished during the polishing process, thus reducing the offset.
[0034] See Figures 1 to 4 In one specific embodiment of the present invention, the grinding end 9 is hinged to the arc rod 7 so that the grinding end 9 can be angled. There are multiple arc rods 7, which are arranged at intervals along the circumference. The connecting frame includes a connecting seat 1, and a first connecting rod 4 connected to the bottom of the connecting seat 1 and the corresponding arc rod 7. The connecting seat 1 is connected to the driver 2.
[0035] Furthermore, such as Figures 1 to 4 As shown, the arc-shaped rod 7 can move up and down along the first connecting rod 4 via the movable node 8, thereby changing the setting angle of the grinding mechanism. By connecting multiple springs 3 to the bottom of the connecting seat 1, pressure can be applied to deform the springs 3 and change their angle. The angle change can drive the grinding end to expand or shrink the grinding angle, thereby changing the grinding range. A movable shaft is set at the connection between the second connecting rod 6 and the arc-shaped rod 7, so that the middle section of the arc-shaped rod 7 is fixed. When one end of the arc-shaped rod 7 moves upward, the other end will move downward to adjust the angle. By setting three first connecting rods 4 to fit the arc-shaped rod 7, and also setting three second connecting rods 6 on the plate 5 to connect the corresponding arc-shaped rods 7, the arc-shaped rod 7 can be subjected to force simultaneously when pressure is applied. Furthermore, by setting three corresponding arc-shaped rods 7 and grinding end 9, the same part can be ground multiple times while rotating one revolution, which can improve the grinding efficiency of the device.
[0036] A grinding method for a steel structure sphere welding area grinding device includes the following steps: The grinding apparatus of claim 1 is provided, wherein the driver of the grinding apparatus is held and the grinding end is pressed against the welded part of the steel structure sphere to be ground; The driver of the downward grinding device rotates the arc-shaped rod around the hinge with the connecting frame, and the distance between the grinding end and the rotation axis of the driver is matched with the radius of the welding part to be ground, so that the rotation axis of the driver is aligned with the center of the welding part to be ground. The driver is activated to rotate the connecting frame and the arc-shaped rod, which in turn causes the grinding head to rotate around the rotation axis of the driver to grind the welded parts.
[0037] The provided grinding device also includes an adjusting component between the arc-shaped rod and the connecting frame, which applies a rotational force to the arc-shaped rod in a direction away from the connecting frame; When the driver of the grinding device is pressed down, the connecting frame moves downward, causing the arc-shaped rod to rotate and be adjusted by the reverse force of the steel structure ball to be ground. At the same time, the arc-shaped rod is also subjected to the force applied by the adjusting component. The force applied by the adjusting component can balance the reverse force of the steel structure ball to be ground so that the arc-shaped rod remains stable.
[0038] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
