DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] An embodiment provided by the utility model: Figure 1 As shown, a flange side grinding device includes an operating table 1, a bottom rail 2, a flange supporting and moving mechanism 3, a clamping mechanism 4, a rotating handle 5, a grinding mechanism 6 and a flange 7.

[0029] The upper fixed connection flange of the operating platform 1 supports the moving mechanism 3, such as Figure 2 and Figure 3 As shown, the flange support moving mechanism 3 includes a first hydraulic rod fixing seat 31, a first hydraulic rod 32, a support assembly 33 and a pulley 34. The support assembly 33 includes a moving seat 331, a lifting frame 332 and a support plate 333. A gasket 334 is provided above the support plate 333. The gasket 334 is made of a flexible material and has an arc-shaped upper surface. The bottom of the flange 7 to be ground is placed above the support plate 333, and the flange 7 stands vertically on the gasket 334. The surface of the gasket 334 is deformed according to the circumferential size of the flange 7 to be ground, so as to improve the fit with the bottom surface of the flange 7 and stabilize the support flange 7 during the movement of the support assembly 33.

[0030] like Figure 3 As shown, the output end of the first hydraulic rod 32 is connected to the support assembly 33, and a pulley 34 is provided at the bottom of the support assembly 33. Figure 1As shown, the surface of the operating table 1 is provided with a bottom rail 2, and the support assembly 33 is slidably connected to the operating table 1. The first hydraulic rod 32 drives the support assembly 33 to move toward the grinding mechanism 6. When the longitudinal center line of the side of the flange 7 to be ground is consistent with the longitudinal center line of the clamping mechanism 4, the movement stops, and the clamping mechanism 4 clamps the flange 7 at this position, making the fixation more balanced and stable. The sliding structure of the support assembly 33 can ensure that flanges 7 of different thickness specifications are all moved to the corresponding position of the center of the clamping mechanism 4, so the device is suitable for grinding flanges 7 of various thickness specifications.

[0031] like Figure 3 As shown, the support plate 333 forms a lifting structure through the lifting frame 332 and the moving seat 331. The lifting frame 332 is provided with a lifting drive member inside, and the clamping mechanism 4 includes a flange fixing assembly 43, which drives the support plate 333 to move upward, so that the transverse center line of the grinding flange 7 reaches the center height position of the flange fixing assembly 43 of the clamping mechanism 4, so that the flange 7 is more stable when the clamping mechanism 4 is fixed. After the clamping mechanism 4 fixes the flange 7 to be ground, the lifting frame 332 drives the support plate 333 to move downward, and the support plate 333 is no longer needed to support the bottom of the flange 7. The bottom of the flange 7 is separated from the gasket 334, which reduces the impact during the grinding operation and ensures that the edge position around the flange 7 completes the grinding operation better.

[0032] like Figure 4 As shown, the clamping mechanism 4 is located on both sides of the flange 7. The clamping mechanism 4 includes a clamping bracket 41, a rotating connector 42 and a flange fixing assembly 43. The flange fixing assembly 43 is installed on the side of the clamping bracket 41 close to the flange 7. The flange fixing assembly 43 includes a rotating plate 431, a second hydraulic rod 432, a push plate 433 and a flange stopper 434. The push plate 433 is fixed at the output end of the second hydraulic rod 432. The flange stopper 434 and the push plate 433 form a telescopic structure through the second hydraulic rod 432 and the flange stopper 434. The second hydraulic rods 432 on both sides simultaneously drive the push plate 433 to move toward the center, so that the flange stoppers 434 on both sides clamp and fix the flange 7 to be ground. The telescopic structure of the push plate 433 and the second hydraulic rod 432 makes the device suitable for grinding flanges 7 of various diameters and sizes, increases the processing range, and improves the practicality of the device.

[0033] like Figure 5As shown, the flange stopper 434 includes a spring 4341, a stopper sheet 4342 and a silicone pad 4343. The stopper sheet 4342 is tilted and movably connected to the push plate 433 through the spring 4341. The silicone pad 4343 is made of a flexible material. Multiple groups of flange stoppers 434 are fixed on the push plate 433. The flange stoppers 434 are symmetrically arranged about the push plate 433. The flange stoppers 434 are fixed on both sides of the flange 7 to be ground. Under the action of the spring 4341, the stopper sheet 4342 changes the angle to maximize the contact area according to the edge curvature of the flange 7. At the same time, the silicone pad 4343 between the stopper sheet 4342 and the flange 7 improves the fit and increases the friction between the two, which has an anti-slip effect. This makes the clamping of the entire clamping mechanism 4 more stable, ensures that the flange 7 will not be offset during the grinding process, and improves the quality of flange processing.

[0034] like Figure 3 As shown, a limit frame 335 is provided above the support plate 333, and the limit frame 335 is at a right angle to the support plate 333. The limit frame 335 and the support plate 333 form a rectangular ring, which is in close contact with the surface of the flange 7 to be ground, and strengthens the stable support of the flange 7 during grinding, always keeps the side opening of the flange 7 parallel to the grinding head 635, and improves the surface level of the flange 7. Before the grinding operation, the support plate 333 moves downward, and for the flange 7 with a raised shape in the center, the limit frame 335 moves up and down, and the raised shape part is always in the central hollow part of the limit frame 335.

[0035] like Figure 6 As shown, the grinding mechanism 6 includes an outer shell 61, a large motor 62 and a rotating grinding assembly 63. The rotating grinding assembly 63 is fixedly connected to the output end of the large motor 62. The rotating grinding assembly 63 is located at the opening position on the surface of the outer shell 61. The rotating grinding assembly 63 and the outer shell 61 form a rotating structure. The large motor 62 drives the rotating grinding assembly 63 to rotate. The rotating grinding assembly 63 rotates on the side of the outer shell 61. The rotating grinding assembly 63 is coaxial with the flange 7 to be ground. The rotating grinding assembly 63 realizes a grinding operation on the flange 7 to be ground once the rotating grinding assembly 63 rotates one circle.

[0036] like Figure 7As shown, the rotary grinding assembly 63 includes a rotary housing 631, a third hydraulic rod 632, a small motor 633, a fourth hydraulic rod 634 and a grinding head 635. The rotary housing 631 is fixedly connected to the body of the third hydraulic rod 632, the output end of the third hydraulic rod 632 is fixedly connected to the body of the small motor 633, the output end of the small motor 633 is fixedly connected to the body of the fourth hydraulic rod 634, and the output end of the fourth hydraulic rod 634 is threadedly connected to the grinding head 635. The third hydraulic rod 632 drives to adjust the distance between the small motor 633 and the rotary housing 631, and the fourth hydraulic rod 634 drives to adjust the position of the grinding head 635 to reach the surface of the flange 7 to be ground. The small motor 633 drives the fourth hydraulic rod 634 and the grinding head 635 to rotate, so that the grinding head 635 can grind the flange 7 to be ground. The third hydraulic rod 632 can adjust the grinding head 635 to the position to be ground according to the size of the flange 7 to be ground, and can perform grinding operations on the flange 7 whose protrusion in the middle is not in the same plane. It has a wide range of applications and strong practicality.

[0037] like Figure 4 As shown, the flange fixing assembly 43 is rotatably connected to the clamping bracket 41 through the rotating connector 42, and the clamping mechanism 4 on the right side is provided with a rotating handle 5, which includes a connecting shaft 51 and a handle 52, and the connecting shaft 51 passes through the rotating connector 42 and is fixedly connected to the flange fixing assembly 43. When the side opening of the flange 7 to be ground is ground, the staff rotates the handle 52 of the right flange fixing assembly 43, which can drive the two sets of flange fixing assemblies 43 and the flange 7 to be ground to rotate together and flip to the other side. The limit frame 335 is again attached to the surface of the flange 7 to be ground under the movement of the support assembly 33, and the side opening of the flange 7 is kept parallel to the grinding head 635. Then the other side is ground according to the same steps. The double-sided grinding operation of the same flange 7 saves manual operation steps and improves processing efficiency.

[0038] The above is only an embodiment of the utility model, and the common sense such as the known specific structure and characteristics in the scheme is not described too much here. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
