Description

Technical Field

[0001] The utility model relates to the technical field of multi-head drilling machines, in particular to a pump cover flange multi-head drilling machine. Background Art

[0002] Flange is a part that connects pipes to each other, valve accessories, etc. Flanges are divided into threaded flanges, welding flanges, and ferrule flanges. They are an important connection method for pipeline construction. Flange connection is to fix two sections of pipes, pipe fittings or pipeline accessories on a flange respectively, and put the gasket between the sealing surfaces of the two flanges. There are bolt holes on the flanges. Insert the bolts into the bolt holes of the flanges. After tightening the nuts, the gasket deforms after the specific pressure on the surface reaches a certain value, and fills the microscopic unevenness on the sealing surface, so that the two flanges are tightly connected without leakage. The bolt holes need to be drilled. In order to better drill the pump cover flange, a pump cover flange multi-head drilling machine is proposed.

[0003] For example, a flange drilling machine disclosed in the authorization announcement number CN215545134U includes a workbench, a mounting frame, a clamping assembly and a drilling assembly. The mounting frame and the clamping assembly are respectively arranged on both sides of the top of the workbench, and the drilling assembly is slidably arranged on the side of the mounting frame, and the drilling assembly corresponds to the clamping assembly vertically;

[0004] Although the dust cover cooperates with the U-shaped plate to provide a guiding effect for the iron chips, so as to facilitate the subsequent unified cleaning, during the drilling process, the cooling water dissipates the heat around the milling head from the inside to the outside, thereby improving the uniformity of heat dissipation. The utility model has a simple structure and uses a rotating drive member and a transverse drive member to perform precise drilling operations on the flange.

[0005] However, the problem that the existing multi-head drilling machine is not conducive to convenient outward expansion clamping to fix the pump body flange and convenient relative movement to adjust the drilling position when in use, is not conducive to circular rotation to adjust the hole position to drill holes in sequence and adapt to pump body flanges of different diameters, affects the convenience and flexibility of drilling.
