Description

Technical Field

[0001] The utility model relates to the technical field of butterfly valve processing, in particular to a rocker drill for butterfly valve processing. Background Art

[0002] Butterfly valves, also known as flap valves, are mostly castings and are a type of regulating valve with a simple structure. When the butterfly valve housing is cast, a flange is generally cast on the butterfly valve body to achieve installation between the valve body and the pipeline. When the butterfly valve is manufactured, it is necessary to drill holes on the flange of the butterfly valve. During the processing of the butterfly valve, a radial drilling machine is often used to drill holes on the butterfly valve.

[0003] The Chinese patent with publication number CN217370526U is a radial drilling machine for butterfly valve processing. After the spring is squeezed by the extrusion plate and slightly deformed in the direction of the clamping block, the flange can be clamped tightly by the spring's rebound force, solving the problem of the butterfly valve flange shaking or slipping when drilling. However, the butterfly valves that need to be drilled have various specifications, so the diameters on the butterfly valves are also different. When drilling the butterfly valves, the clamping cannot be adjusted according to the specifications of the butterfly valves, which limits the scope of application of the radial drilling machine. Therefore, a radial drilling machine for butterfly valve processing is designed to solve the above-mentioned problems. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example

[0019] See also Figure 1-3The present embodiment provides a radial drill for processing butterfly valves, including a radial arm 1, a drill bit and a processing bed, wherein the radial arm 1, the drill bit and the processing bed can refer to the publication number: CN217370526U. A base, a driving radial arm and an electric drilling machine in a radial drilling machine for processing butterfly valves are common equipment in the field, so they are not described in detail. A servo motor 2 is fixedly connected to the processing bed of the radial drilling machine 1, and the output end of the servo motor 2 is fixedly connected to a mounting plate 3. The mounting plate 3 is circular, and slide grooves 31 are equidistantly provided on the mounting plate 3. The slide grooves 31 are slidably connected to the mounting rods 5, and the upper end of the mounting rods 5 is fixedly connected to the clamping rod 6.

[0020] Three support plates 4 are fixedly connected to the processing bed centered on the servo motor 2. The upper ends of the support plates 4 are fixedly connected to the support platform 7. The support platform 7 is provided with limit grooves 71 of the same specification as the slide groove 31 at equal intervals, wherein the clamping rod 6 is located in the limit groove 71.

[0021] Place the butterfly valve on the support platform 7, start the servo motor 2, and the rotation of the output end of the servo motor 2 will drive the mounting plate 3 to rotate, and the mounting plate 3 drives the mounting rod 5 to move, and the mounting rod 5 drives the clamping rod 6 to move. The clamping rod 6 at the upper end is blocked by the limit groove 71, so that the clamping rod 6 can only approach the center of the support platform 7 along the trajectory of the limit groove 71, so that multiple clamping rods 6 are close to the butterfly valve body until the butterfly valve is clamped, and then the servo motor 2 is stopped, and then the radial drilling machine 1 is used to drill the butterfly valve.

[0022] By the way that the clamping rod 6 is arranged to move spirally and approach the butterfly valve on the support platform 7, the clamping rod 6 is fixed to the side wall of the butterfly valve after contacting it, so that the position of the clamping rod 6 can be adjusted according to the diameter of the butterfly valve, so that the clamping rod 6 can clamp butterfly valves of different diameters, so that the radial drilling machine 1 has a wider application range.

[0023] A material receiving frame 9 is rotatably connected to the outer side of the mounting plate 3, a conical guide block 8 is also fixedly connected to the middle of the upper end of the mounting plate 3, and a material discharge port 72 is opened in the middle of the support platform 7. The crushed materials generated during punching fall from the material discharge port 72 and the limiting groove 71, and are guided by the conical guide block 8 and fall into the material receiving frame 9 on the side.

[0024] At the same time, a through opening 32 is provided in the chute 31, and the through opening 32 is also used for the debris to fall, so as to prevent the debris from accumulating on the mounting plate 3. Specifically, when the mounting plate 3 drives the mounting rod 5 to move in the chute 31, the mounting rod 5 will push the debris to fall from the through opening 32, so that the debris falls on the processing bed, which is convenient for cleaning.

[0025] During use, when placing butterfly valves of different diameters, it is only necessary to place the butterfly valve in the middle of the support platform 7, keep the distance between the flange and each clamping rod 6 equal, then start the servo motor 2, the rotation of the output end of the servo motor 2 will drive the mounting plate 3 to rotate, the mounting plate 3 drives the mounting rod 5 to move, the mounting rod 5 drives the clamping rod 6 to move, and the clamping rod 6 at the upper end is blocked by the limiting groove 71, so that the clamping rod 6 can only move along the trajectory of the limiting groove 71 toward the center of the support platform 7, so that multiple clamping rods 6 clamp the butterfly valve.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
