Description

TECHNICAL FIELD

[0001] The application relates to the technical field of welded pipe fixing, in particular to a quick fixing device for grinding the pipe opening of a stainless steel welded pipe. BACKGROUND

[0002] Welded steel pipe, also known as welded pipe, is a steel pipe made by winding and welding a steel plate or strip, generally with a length of 6 meters. The production process of welded steel pipe is simple, the production efficiency is high, the variety and specification are various, the equipment investment is small, but the strength is generally lower than that of seamless steel pipe. In the production process of high-frequency welded pipe, the pipe openings at both ends of the welded pipe need to be ground.

[0003] The grinding device on the current market is relatively simple in design, mainly a handheld grinder. In the use process, the worker needs to continuously hold the grinder to grind the stainless steel pipe body which has been fixed. This operation method not only consumes manpower, but also due to the limitation of human posture and strength, the ground stainless steel pipe body port is often not flat enough and the quality is relatively poor.

[0004] For example, in the prior art, the Chinese utility model patent with the authorization announcement number CN215470100U discloses a "pipe opening grinding device", which comprises a base plate, a motor and a grinding structure. The surface of the base plate is fixedly connected with a fixing frame, the inner wall of the fixing frame is provided with a stainless steel pipe body, the surface of the base plate is provided with a grinding structure, the grinding structure comprises a U-shaped frame, the U-shaped frame is fixedly connected with the surface of the base plate, the inside of the U-shaped frame is slidably connected with a limiting frame, the inner wall of the limiting frame is fixedly connected with the motor, the output shaft is fixedly connected with the motor rotor, the output shaft is fixedly connected with a connecting frame at the end away from the motor, the inside of the connecting frame is slidably connected with two sliding frames, the second sandpaper is glued on the side of the two sliding frames close to each other, and the first sandpaper is glued on the surface of the connecting frame. The utility model solves the problems of waste of manpower and poor quality of the ground product port of the existing grinding device.

[0005] The prior art stainless steel welded pipe port grinding device including the above patent does improve the product quality to a certain extent, but still has some deficiencies in actual application. First, the existing device is relatively cumbersome to operate when adjusting the grinding depth of the welded pipe port. Generally, the grinding depth of the welded pipe port needs to be accurately controlled according to actual needs to ensure the quality and performance of the welded pipe. However, in actual operation, the existing device needs to be first released from the fixed frame, then manually pushed to move on the fixed frame to adjust the grinding depth of the welded pipe. This process is not only time-consuming and labor-intensive, but also difficult to move inside the fixed frame, which may cause the welded pipe to stick to the inner wall of the fixed frame and move. This not only makes the movement inflexible, but also easily causes the outer wall of the welded pipe to be rubbed by the inner wall of the fixed frame. If the welded pipe is lifted by the staff for operation, although it can be moved on the inner wall of the fixed frame, this method relies too much on manual operation, which not only wastes time, but also may cause poor grinding effect of the welded pipe port due to operation errors, thereby affecting the overall quality of the product.

[0006] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it can include prior art known to those skilled in the art. Content of the utility model

DETAILED DESCRIPTION

[0023] The following will be described in detail in combination with the accompanying Figure 1 -Appendix Figure 3 The application is further described in detail.

[0024] The embodiment of the application discloses a quick fixing device for grinding the pipe orifice of stainless steel welded pipe. Figures 1-3 A quick fixing device for grinding the pipe orifice of stainless steel welded pipe, comprising a workbench 1, the bottom of the workbench 1 is fixed with support legs 2 at four corners, and the top is fixed with a support frame 3, the top of the support frame 3 is fixed with a first motor 4, the output end of the first motor 4 is installed with a grinding wheel 5 through bolts, and the top surface of the workbench 1 is further fixed with two pairs of support plates 6, and the two pairs of support plates 6 are rotatably linked with rollers 7;

[0025] The height adjusting assembly is connected with the workbench 1, and the height adjusting assembly comprises a fixed frame 15, a double-shaft motor 20, two screw rods 21, two guide blocks 19, two U-shaped frames 16, two V-shaped clamping plates 17 and two installation grooves 9.

[0026] Referring to Figure 1 and Figure 2The height-adjusting assembly further comprises two connecting plates 13 connected to the bottom of the fixed frame 15 through pivots, and the bottom of the workbench 1 is further fixed with two pairs of fixed plates 10, each of which is rotatably connected with a bidirectional threaded rod 11, and a second motor 14 for driving the bidirectional threaded rod 11 to rotate is installed on the fixed plate 10, and the outer wall of the bidirectional threaded rod 11 is threadedly provided with two symmetrically distributed moving plates 12, and the two connecting plates 13 are respectively connected to the two moving plates 12 through pivots; in use, first, the second motor 14 is started to drive the bidirectional threaded rod 11 to rotate, and since the outer wall of the bidirectional threaded rod 11 is threadedly provided with two symmetrically distributed moving plates 12, the two moving plates 12 will move relatively or oppositely along the axis direction of the bidirectional threaded rod 11 with the rotation of the bidirectional threaded rod 11, and since the two connecting plates 13 are respectively connected to the two moving plates 12 through pivots, the two moving plates 12 will drive the fixed frame 15 to move up and down when the two moving plates 12 move, and this up-and-down movement can accurately adjust the height of the V-shaped clamping plate 17 so as to facilitate the clamping of the V-shaped clamping plate 17 on the welded pipes with different diameters.

[0027] With reference to Figure 2 Each of the two pairs of fixed plates 10 is further fixed with a pair of guide rods 23, and the guide rods 23 penetrate the moving plates 12; the stability of the moving plates 12 during movement can be increased, and they are not easy to shake.

[0028] With reference to Figure 2 The outer wall of the bidirectional threaded rod 11 between the two moving plates 12 is fixed with a fixed tube 24; the positions of the two moving plates 12 can be limited, and the connecting plates 13 are prevented from being in a vertical state.

[0029] With reference to Figure 2 and 3 The U-shaped frame 16 and the V-shaped clamping plate 17 are fixed with a reinforcing rib 18; the stability of the U-shaped frame 16 and the V-shaped clamping plate 17 can be increased, and the V-shaped clamping plate 17 is not easy to bend when clamping the welded pipe.

[0030] With reference to Figure 1 The outer wall of each of the two rollers 7 is provided with an arc-shaped groove 8; when the welded pipe is pushed by the staff, it can be located in the middle of the roller 7 to prevent it from falling off.

[0031] With reference to Figure 2 The materials of the two pairs of connecting plates 13 are metal materials; they are not easy to break or bend, and the service life thereof can be prolonged.

[0032] The implementation principle of the quick fixing device for grinding the pipe opening of stainless steel welded pipe is as follows: when in use, first, the worker places the stainless steel welded pipe with the port to be ground on the two rollers 7 on the workbench 1, so that the welded pipe is located in the middle of the V-shaped clamping plate 17, at this time, the stainless steel welded pipe with the port to be ground can be attached to the grinding wheel 5 by pushing the welded pipe to move, then, the double-shaft motor 20 is started, the double-shaft motor 20 drives the two screw rods 21 to rotate synchronously, since the guide block 19 is connected with the screw rod 21 through threads, when the screw rod 21 rotates, the guide block 19 moves along the direction of the guide groove 22, so that the two U-shaped frames 16 are close to or away from each other, thereby realizing quick fixing of the welded pipe, after fixing is completed, the worker can start the first motor 4 to drive the grinding wheel 5 to rotate, so that the welded pipe can be ground.

[0033] When the depth of grinding of the welded pipe needs to be adjusted, the first motor 4 is stopped, and the double-shaft motor 20 is started again, so that the V-shaped clamping plate 17 is separated from the outer wall of the welded pipe, since the two rollers 7 are used to assist supporting the welded pipe, the worker can push the welded pipe to move on the rollers 7, then, the double-shaft motor 20 and the first motor 4 are started respectively, so that the welded pipe can be fixed and ground, and the depth of grinding of the port of the welded pipe can be adjusted, which not only facilitates moving the grinding position of the port of the welded pipe, but also avoids the problem that the welded pipe is easily rubbed during movement.
