Description

Technical Field

[0001] This utility model relates to the field of tooling for welding, specifically to a clamping device used for welding sand-sweeping pipes on an electroplated diamond wire saw production equipment. Background Technology

[0002] Diamond wire saws are widely used in photovoltaic silicon wafer cutting and are a key auxiliary material in the process. Therefore, the production of diamond wire saws requires improved process stability to consistently ensure product quality. The sand-sweeping tube, as a critical piece of equipment in the process, directly affects the product quality of the diamond wire saw due to the uniformity of its sand output and the stability of its agitation of the plating solution. Uneven sand output can lead to sand accumulation, gaps, or even uneven sand application, resulting in sections with too much sand, too little sand, or no sand at all. Therefore, the processing, welding, and installation of the sand-sweeping tube must meet the design requirements and acceptance standards. Currently, welding the sand-sweeping tube is often done by hand or simply by clamping it. This is unsafe, results in significant welding errors, and makes it impossible to provide products of the same standard from different batches or by different operators. Summary of the Invention

[0003] To overcome the shortcomings of the existing technology, this utility model provides a clamping device for welding sand-cleaning pipes, the specific technical solution of which is as follows:

[0004] A clamping device for welding sand sweeping pipes includes a base plate 1, a V-block 2, and a flange fixing plate 3. The V-block 2 and the flange fixing plate 3 are both perpendicular to and fixedly connected to the base plate 1. The V-block 2 is used to fix the horizontal part of the sand sweeping pipe, and the flange fixing plate 3 is used to fix the vertical part of the sand sweeping pipe.

[0005] It also includes a reinforcing plate 4 for securing the flange fixing plate 3.

[0006] It also includes a baffle 5 for stabilizing the sand-sweeping pipe and a knurled flat-head screw 6.

[0007] The number of V-shaped blocks 2 is 2-4, which can be 2, 3 or 4.

[0008] This utility model provides a welding fixture that enables efficient and high-quality rapid welding of sand-sweeping pipes on all diamond wire saw production equipment. It includes a base plate 1, a V-block 2, a flange fixing plate 3, a reinforcing plate 4, a baffle 5, and knurled flat head screws 6. The base plate 1, V-block 2, and flange fixing plate 3 are all positioned using two pins on one side and secured with screws. Using this fixture ensures the perpendicularity and straightness of the welding between the inner and outer pipes, guarantees the overall welding quality of the sand-sweeping pipe, and improves welding efficiency. This fixture is characterized by its small size, low manufacturing cost, maintenance-free operation, and ease of use. Attached Figure Description

[0012] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0013] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., used to indicate orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0014] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0015] like Figure 1 As shown, this utility model provides a clamping device for welding sand-sweeping pipes, including a base plate 1, a V-shaped block 2, a flange fixing plate 3, a reinforcing plate 4, a baffle 5, and knurled flat-head screws 6. The V-shaped block 2 and the flange fixing plate 3 are both perpendicular to and fixedly connected to the base plate 1. The V-shaped block 2 is used to fix the horizontal part of the sand-sweeping pipe (the main body of the outer pipe 8), and the flange fixing plate 3 is used to fix the vertical part of the sand-sweeping pipe (the part of the inner pipe 7 that is not fitted with the outer pipe 8, which includes the flange). A structural schematic diagram of the sand-sweeping pipe is shown below. Figure 2 As shown.

[0016] The base plate 1, V-block 2, and flange fixing plate 3 are all positioned using two pins on one side and fastened with screws. This invention is a specific application on an electroplated diamond wire saw equipment. Before welding, the inner and outer tubes of the sand-sweeping pipe are fitted together. The V-block 2 is used to fix the horizontal part of the sand-sweeping pipe. Preferably, it may also include a baffle 5 fixed on the base plate 1, which cooperates with the V-block 2 to fix the sand-sweeping pipe. Then, the flange of the inner tube of the sand-sweeping pipe is fixed at the corresponding height position in conjunction with the flange fixing plate 3. It may also include a reinforcing plate 4 fixed on the base plate 1, which is used to stabilize the flange fixing plate 3. Press the knurled flat-head screws 6 on the outer tube to make the outer tube and the inner tube fit tightly. Spot weld the joint of the inner and outer tubes, and then perform full welding in batches. The above disclosure is only a specific embodiment of this utility model on an electroplated diamond wire saw production equipment. However, this utility model is not limited to this. Any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
