Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel welded pipe grinding, in particular to a stainless steel welded pipe weld grinding device. Background Art

[0002] After the stainless steel pipes are welded, the weld between the two stainless steel pipes needs to be polished to ensure the flatness of the outer surface of the stainless steel pipe. In the prior art, the two ends of the stainless steel pipe are generally clamped by a clamp, and then polished by a grinder. During the use of such a structural design, if the position of the weld is close to the two ends of the stainless steel pipe, the clamp will be very close to the position of the weld, and the protrusion of the clamp will affect the normal operation of the grinder, which is inconvenient to use.

Through the mutual cooperation of the weld grinding installation assembly, the stainless steel pipe drive end limit assembly and the stainless steel pipe limit assembly, when in use, locking is performed from the inner side of both ends of the stainless steel pipe to eliminate the obstruction of the clamp protrusion. In this way, even if the stainless steel weld is close to the two ends of the stainless steel pipe, it can be ground normally, which is convenient for operation.

[0004] In order to solve the above technical problems, according to one aspect of the utility model, the utility model provides the following technical solution: a stainless steel welded pipe weld grinding device, comprising:

[0005] A weld grinding installation assembly, the weld grinding installation assembly comprising a concave installation frame, a rotating motor arranged inside the concave installation frame, an output shaft connected to the rotating motor, a first clamping locking block connected to the output shaft, and a grinding sheet mounting frame arranged on the surface of the concave installation frame;

[0006] A stainless steel pipe driving end limit assembly, the stainless steel driving end limit assembly comprising a cylinder arranged inside the first clamping and locking block, a hydraulic rod connected to the cylinder, a first arc-shaped notch opened on the surface of the first clamping and locking block, and an arc-shaped pressing block connected to the top end of the hydraulic rod;

[0009] As a preferred solution of the stainless steel welded pipe weld grinding device described in the utility model, a corresponding hydraulic rod is provided at the position of each first arc-shaped notch;

[0010] Wherein, the hydraulic rod drives the arc-shaped pressing block to move up and down.

[0015] Compared with the prior art, the advantages of the utility model are:

[0016] 1. The utility model cooperates with each other through the weld grinding installation assembly, the stainless steel pipe drive end limit assembly and the stainless steel pipe limit assembly, so that when in use, locking is performed from the inner side of both ends of the stainless steel pipe, eliminating the obstruction of the clamp protrusion, so that even if the stainless steel weld is close to the two ends of the stainless steel pipe, it can be ground normally, which is convenient for operation.

[0017] Second, based on the first beneficial effect, a step-shaped clamping and locking block is formed by setting a connecting component, which is directly applicable to the grinding of stainless steel pipes of different diameters, thereby improving applicability.

At this time, the rotating motor drives the output shaft to rotate, so that the entire stainless steel pipe can be driven to rotate. At this time, a grinding sheet is installed on the surface of the grinding sheet mounting frame, and the grinding sheet is directly fitted with the weld position, so that grinding can be performed, eliminating the influence of the fixture protrusion on the weld position.

In this way, even if the stainless steel weld is close to the two ends of the stainless steel pipe, it can be ground normally, which is convenient for operation.

[0029] Example 1

[0030] Figure 1 , Figure 2 and Figure 3 The utility model is a schematic diagram of the overall structure of a stainless steel welded pipe weld grinding device according to an embodiment of the present invention. Figure 1 , Figure 2 and Figure 3 The main structure of this embodiment includes: a weld grinding installation assembly, a stainless steel pipe driving end limit assembly and a stainless steel pipe limit assembly.

[0031] The weld grinding installation assembly is used for driving and installation. Specifically, the weld grinding installation assembly includes a concave installation frame 11, a rotating motor 12 arranged inside the concave installation frame 11, an output shaft 13 connected to the rotating motor 12, a first clamping locking block 14 connected to the output shaft 13, and a grinding sheet mounting frame 15 arranged on the surface of the concave installation frame 11;

[0032] During specific use, the rotating motor 12 drives the output shaft 13 to rotate, thereby driving the entire stainless steel pipe to rotate. At this time, a grinding sheet is installed on the surface of the grinding sheet mounting frame 15, and the grinding sheet is directly attached to the weld position, so that grinding can be performed.

[0033] The stainless steel pipe driving end limit assembly is used to cooperate with the stainless steel pipe limit assembly to limit and lock the stainless steel pipe from the inside of both ends. Specifically, the stainless steel driving end limit assembly includes a cylinder 21 arranged inside the first clamping and locking block 14, a hydraulic rod 22 connected to the cylinder 21, a first arc-shaped notch 23 opened on the surface of the first clamping and locking block 14, and an arc-shaped pressing block 24 connected to the top of the hydraulic rod 22; the stainless steel pipe limit assembly, the stainless steel pipe limit assembly includes a circular hole 31 opened on the side wall of the concave mounting frame 11, a rotating shaft 32 passing through the circular hole 31, a second clamping and locking block 33 connected to the rotating shaft 32, a circular plate 34 connected to the top of the rotating shaft 32, and an electric telescopic rod 35 connecting the circular plate 34 to the concave mounting frame 11;

[0034] During specific use, the user places the stainless steel pipe between the concave mounting frame 11 and fits one end of the stainless steel pipe on the surface of the first clamping and locking block 14. At this time, the hydraulic rod 22 drives the arc clamping block 24 to move, and the arc clamping blocks 24 in the three positions are pushed forward and fit against the inner side of the stainless steel pipe, directly tightening the stainless steel pipe from the inside. At this time, the electric telescopic rod 35 drives the circular plate 34 to move the rod, thereby driving the rotating shaft 32 to move forward until the second clamping and locking block 33 is engaged in the stainless steel pipe. Since the second clamping and locking block 33 has the same structure as the first clamping and locking block 14, the other end of the stainless steel pipe is directly locked from the inside, so that the two ends of the stainless steel pipe can be locked from the inside. At this time, the rotating motor 12 drives the output shaft 13 to rotate, so that the entire stainless steel pipe can be driven to rotate. At this time, a grinding sheet is installed on the surface of the grinding sheet mounting frame 15, and the grinding sheet is directly fitted with the weld position, so that grinding can be performed to eliminate the influence of the fixture protrusion on the weld position.

[0035] Example 2

[0036] Please refer to Figure 1 and Figure 2 , through the setting of the connection components, a step-shaped clamping and locking block is formed, which is directly applicable to the grinding of stainless steel pipes of different diameters, thereby improving the applicability;

[0037] Specifically, it also includes a connecting assembly, which includes a third clamping and locking block 41 and a fourth clamping and locking block 42 connected between the output shaft 13 and the first clamping and locking block 14;

[0038] The surfaces of the third clamping and locking block 41 and the fourth clamping and locking block 42 are both provided with second arc-shaped notches 43 of the same structure;

[0039] During specific use, the diameters of the first clamping and locking block 14, the fourth clamping and locking block 42 and the third clamping and locking block 41 are increased successively to form a step shape. In this way, when used for stainless steel pipes with different diameters, the clamping and locking blocks with different diameters can be fitted onto the stainless steel pipes and used directly without targeted adjustments, thereby improving the grinding efficiency.

[0040] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
