Clamp for flange plate drilling

Abstract

The invention provides a clamp for flange plate drilling. The clamp comprises a base, a fixing plate, an index plate and a three-jaw chuck, wherein the fixing plate, the index plate and the three-jaw chuck are sequentially arranged on the base from bottom to top. The fixing plate is fixedly connected with the base and provided with a through hole. The index plate penetrates the through hole of the fixing plate and is connected with the base in a rotating manner. A slewing mechanism is arranged between the index plate and the base. By driving the slewing mechanism, the index plate can rotate relative to the fixing plate. The three-jaw chuck is coaxially fixed to the index plate. The base is further provided with a drilling die which is located above the base and does not make contact with the fixing plate, the index plate or the three-jaw chuck. The drilling die is provided with a center hole. The axis of the center hole is parallel to the axis of the index plate. The base is provided with a support. The drilling die is connected with the base through the support. The circle center of the center hole of the drilling die can do horizontal motion along the diameter of the index plate. When a flange plate is drilled, the clamp can be adjusted to drill flange holes of different specifications, the clamp is simple in structure, and the production cost is reduced while manual operation is facilitated.

Description

technical field [0001] The invention belongs to the field of fixtures, in particular to a fixture used for drilling flanges. Background technique [0002] In our modern life, flanges are relatively common, especially in the field of machinery, which is quite extensive. Flanges are important parts for connecting various pipes and valves, usually connected to pipe ends, for two There are certain requirements for the position of the bolt holes when the flange is matched. Now the more commonly used drilling method is to use a drilling machine to complete the process. For pipes with different diameters, the number, diameter, and center distance between the flange holes They are also different, and their special fixtures are often made according to their different needs, which wastes manpower and material resources and increases production costs. In view of this situation, a jig for drilling flanges according to the present invention can complete drilling through one jig for flan...
