Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, and in particular to a grinding device for header pipes. Background Technology

[0002] The main function of the header is to collect the boiler working fluid or redistribute the working fluid to other pipelines through the header. It usually has a cylindrical body and several branch pipes set on the side of the cylindrical body. In order to facilitate the connection with other pipelines, there are certain requirements for the precision and smoothness of the inner wall of the branch pipes, which need to be ground by a grinding machine.

[0003] A typical hole grinding machine includes a frame with a chuck disc at the top. Hollow pipe fittings are fixed to the top of the chuck disc. A motor is also mounted on the frame, with a grinding head located below the motor. The grinding head is raised and lowered to grind the interior of the hollow pipe fitting. This type of hole grinding machine is only suitable for grinding the inner walls of small-sized hollow pipes. A single chuck disc is insufficient to hold long headers and does not provide enough space to grind the numerous branch pipes on the sides of the header.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0021] First embodiment: This embodiment discloses a device for grinding header pipes.

[0022] like Figure 1 As shown, the header pipe grinding device includes a base 2, a bracket 4, a header 3, and a three-axis gantry frame 1.

[0023] The base 2 is placed on the ground. For example, the base 2 is a cuboid structure.

[0024] At least two brackets 4 are arranged parallel and spaced apart on the upper end of the base 2. The header 3 passes through two brackets 4 at each end and is connected to the two brackets 4 with clamps. Several branch pipes 32 are arranged vertically upwards on the side. For example... Figure 2As shown, exemplarily, the bracket 4 includes a vertical plate 42, with a first hoop at the upper end of the vertical plate 42, and a second hoop 43 at the upper end of the first hoop. The first hoop and the second hoop 43 form a through hole for the collection box 3 to pass through. Specifically, a semi-circular groove 421 is formed at the upper end of the vertical plate 42, and first ears 422 are provided at the upper ends of both sides of the vertical plate 42. The first ears 422 and the semi-circular groove 421 combine to form the first hoop. The second hoop 43 includes a semi-circular arc plate 431 and second ears 432 provided at both ends of the semi-circular arc plate 431. The inner diameter of the semi-circular arc plate 431 is the same as that of the semi-circular groove 421. The first ears 422 and the second ears 432 are connected by a first fixing member 5. The first fixing member 5 includes a first bolt 51 and a first nut 52. The first bolt 51 passes through the first ears 422 and the second ears 432 and is bolted to the first nut 52.

[0025] like Figure 3 As shown, the header 3 includes a cylindrical body 31, with the portions of the cylindrical body 31 without branch pipes 32 passing through a through hole formed by the first hoop and the second hoop 43. Preferably, gaskets (not shown in the figure) are provided between the cylindrical body 31 and the semi-circular plate 431, and between the outer side of the cylindrical body 31 and the semi-circular groove 421, to improve the firmness of the fixing between the cylindrical body 31 and the bracket 4, and at the same time, to accommodate headers 3 with different outer diameters.

[0026] like Figure 1 As shown, the three-axis gantry frame 1 is erected on the ground. A motor 11 is fixed on the moving end of the three-axis gantry frame 1. The three-axis gantry frame 1 drives the motor 11 to move along the X, Y, and Z axes. A grinding head 12 is set on the output end of the lower end of the motor 11. The grinding head 12 is set vertically. The base 2 is located inside the three-axis gantry frame 1. The moving path of the motor 11 passes through the header 3.

[0027] In this embodiment, when using the header pipe grinding device, the operator moves the header 3 onto the first clamp of the two supports 4, rotates the header 3 so that its branch pipe 32 is vertically upward, and fixes the second clamp 43 to the first clamp through the first fixing member 5, thereby connecting the two ends of the header 3 to the supports 4. The three-axis gantry 1 is started, and the three-axis gantry 1 drives the motor 11 to move along the X, Y, and Z axes until the grinding head 12 extends into the branch pipe 32. The motor 11 is started, and the output end of the motor 11 drives the grinding head 12 to rotate, so as to grind the inner wall of the branch pipe 32. The structure is simple and easy to use. It can fix a long header 3 and grind multiple branch pipes 32 on the side of the header 3.

[0028] Second embodiment: Based on the first embodiment, the second embodiment further optimizes and refines the support 4 of the first embodiment.

[0029] like Figure 2 and Figure 3As shown, a base plate 41 is provided at the lower end of the vertical plate 42, and the two ends of the base plate 41 extend out of the two sides of the vertical plate 42. Several fixed seats 21 are arranged parallel to each other along the length direction at the upper end of the base 2, and the fixed seats 21 are parallel to the width direction of the base 2.

[0030] like Figure 3 As shown, further, a T-slot 211 is formed at the upper end of the fixing base 21 along its length direction, and the base plate 41 is connected to the T-slot 211 by two sets of second fixing members 6. The second fixing member 6 includes a T-bolt 61 and a second nut 62. The head of the T-bolt 61 is engaged in the T-slot 211 and can slide along the T-slot 211. The shank of the T-bolt 61 passes through the T-slot 211 and the base plate 41 in sequence and is threadedly connected to the second nut 62.

[0031] In this embodiment, the bracket 4 is fixed to the fixed seat 21 with corresponding spacing according to the length of the container 3. At the same time, according to the number of containers 3, multiple brackets 4 and containers 3 can be fixed side by side on the same fixed seat 21 to improve production efficiency.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
