Description

Technical Field

[0001] This utility model relates to the field of weld seam treatment, and in particular to a grinding device for barrel weld seams. Background Technology

[0002] The barrel body is made by bending and welding single or multiple plates. As a result, multiple weld seams remain on the barrel body after manufacturing, requiring further grinding, polishing and wire drawing. The existing method is to simply fix the barrel body and then manually grind it with a hand-held angle grinder. This method, because the barrel body will roll and be fixed, or even if a fixed grinding equipment is used and the person holds the barrel body to grind it, not only poses safety hazards, but also makes it difficult to standardize the grinding effect, affecting the appearance of the finished product.

[0021] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] When this utility model is in use, the cylindrical barrel is placed on the fixed component, and the vertical movement component and the horizontal movement component drive the grinding component to move unidirectionally from the bottom of the barrel to the opening of the barrel, so as to achieve the effect of grinding the weld. During the process, the cylindrical barrel will not rotate or move back and forth.

[0023] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0024] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0025] As in the background technology, the grinding of the weld seam of a cylindrical barrel is limited by the barrel's tendency to roll, which can cause the grinding to deviate from the weld seam and leave grinding marks in other areas. Alternatively, if the fixing force is too great, the barrel may be ground while deformed, and the grinding effect will change when the barrel is reset after the fixing is released.

[0026] Furthermore, the complex fixtures and the time-consuming loading and unloading of the barrels are not conducive to improving grinding efficiency.

[0027] In response, the technical solution proposed by this utility model is that the grinding motion structure moves in one direction, from the bottom of the barrel to the opening of the barrel, and is supplemented by internal support structures, which can ensure that the barrel does not move during the grinding process and that the barrel can be quickly picked up and put away after grinding, thus improving efficiency.

[0028] Figures 1 to 2 A grinding device for the weld seam of a cylindrical barrel 100 according to an embodiment of the present utility model includes:

[0029] Support 1: includes a vertical motion component 11 and a horizontal motion component 12; the movable end of the vertical motion component 11 is provided with a grinding component 2 that can swing; the swing of the movable end is about the motion axis of the vertical motion component 11. The purpose of the vertical motion component 11 is to make the grinding component 2 contact or move away from the barrel 100. Through vertical movement, when the barrel is placed in, the grinding component 2 can move closer to the barrel to contact and grind; and after grinding, it can move away from the barrel.

[0030] The vertical and horizontal movements work together, allowing the polishing component 2 to move along at least a rectangular path when viewed from the side. Of course, by controlling the movement, an elliptical or even nearly circular motion trajectory can also be achieved.

[0031] Specifically, the vertical motion assembly 11 includes a vertical fixed frame and a vertical movable element. The vertical movable element includes a guide rail and a slider, and the slider is provided with a grinding bracket 21 mounting base. The slider can extend a support arm, and there is an axis parallel to the slider's movement as a rotation axis. The grinding bracket 21 mounting base swings around this rotation axis. The purpose of this structure is to allow the entire grinding bracket 21 mounting base to have more ways of movement.

[0032] Grinding assembly 2: includes a grinding bracket 21 and a movable wheel set 22. The movable wheel set 22 is rotatably mounted on the grinding bracket 21, and the grinding belt is wound around the movable wheel set 22. Specifically, the grinding bracket 21 includes a wheel set mounting plate and a hinge conversion component. The movable wheel set 22 is movably mounted on one side of the wheel set mounting plate, and the hinge conversion component is mounted on the other side. The wheel set mounting plate is swaying on the vertical motion assembly 11 through the hinge conversion component.

[0033] In this embodiment of the utility model, the grinding of the barrel weld seam relies on an operation mode similar to a belt sander, that is, the sanding belt is driven by several movable wheel sets 22 to make linear motion, and rubs against the weld seam after contact. Therefore, the movable wheel sets 22 can be relatively adjusted in distance on the grinding bracket 21. At the same time, a tensioning structure can be set on the grinding bracket 21 to compensate for the problem of the sanding belt becoming thinner after wear, and the problem of the sanding belt having an excessively large contact area with the weld seam.

[0034] The movable end of the lateral motion component 12 is provided with a fixing component 3, which is a fixed component; as mentioned above, the lateral motion component 12 and the vertical motion component 11 constitute a two-axis motion mechanism that can form a rectangular coverage area in the plane.

[0035] Fixed component 3: includes radial fixing component 31, axial support component 32 and telescopic adjustment component 33. The vertical fixing component is located at the movable end of the transverse motion component 12, the transverse support component is fixed to the vertical fixing component, and the telescopic adjustment component 33 is located at the end of the transverse support component and abuts against the bottom inner surface of the cylinder 100.

[0036] The fixing component 3 utilizes the structure of the barrel: the axial support 32 and the telescopic adjustment component 33 enter the barrel from the opening. In some embodiments, the radial fixing component 31, facing the barrel 100, forms several concentric circular steps coaxially, allowing the barrel opening to be secured on the steps. This limits the radial movement of the barrel. The axial support 32 prevents the barrel from being crushed when the grinding component 2 applies downward pressure. The telescopic adjustment component 33, after adjustment, rests against the inner surface of the barrel bottom. Thus, when the grinding component 2 moves from the bottom towards the opening, the radial and axial movement tendencies of the barrel are restricted, and the tendency to rotate around the axial direction is suppressed, achieving barrel fixation during grinding without the need for complex clamps. After grinding, the barrel 100 can be detached simply by pulling it out slightly from the bottom.

[0037] Optionally, the telescopic adjustment component 33 includes a cylinder and a stop plate. The cylinder is fixed to the transverse support component, and the stop plate is located at the telescopic end of the cylinder. The stop plate is set in an arc shape, which can achieve effective support and rotation suppression of the bottom of the barrel.
