Embodiment Construction

[0019] Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail:

[0020] Such as figure 1 As shown, a ring hole processing device in the pump body is composed of a mandrel 1 , a pair of bearing bushes 2 and a tool holder 3 . One end of the mandrel 1 is processed with a taper shank 11 for connection with the CNC machine tool, which is driven to rotate by the CNC machine tool. A pair of bearing bushes 2 are mounted on both ends of the mandrel 1 for supporting the mandrel 1 . During processing, a pair of bearing bushes 2 cooperate with the bearing hole or pump hole of the pump body to position the mandrel 1 to ensure that the mandrel 1 is located at the center of the pump body or coaxial with the rotating shaft of the pump body. Finishing in this way is more precise.

[0021] The knife seat 3 is installed in the middle of the mandrel 1, and the center of the knife seat 3 is processed with a mounting hole 3...

Abstract

The invention relates to the field of pump body finish machining, and provides pump body inner ring hole machining device and process. The device comprises a mandrel, a pair of bearing bushes and a tool apron, a taper shank is machined at one end of the mandrel, the pair of bearing bushes are arranged at the two ends of the mandrel, the tool apron is arranged on the mandrel through an installation hole in the center of the tool apron, a radial adjusting seam is inwards cut in the middle of the tool apron from one side of the tool apron and penetrates through the center of the installation hole, and the adjusting seam enables the tool apron to face one side to be semi-opened. The bearing bushes are matched with a pump hole or a bearing hole of a pump body, so that the actual center line of the pump body and the center line of the mandrel are overlapped and positioned; an upper shell and a lower shell of the pump body are machined at the same time through the tool apron on the mandrel, the size consistency of ring holes of the upper shell and the lower shell is guaranteed, machining of the ring holes in the pump body is achieved through movement of the tool apron on the mandrel, repeated positioning is avoided, and the coaxiality of the ring holes in the pump body is achieved; and according to the technical scheme, the requirements for coaxiality and machining precision of the pump body are met, and the machining efficiency of parts can be improved.

Description

technical field [0001] The invention relates to the field of finish machining of a pump body, in particular to an annular hole processing device and process in the pump body. Background technique [0002] Pumps are widely used in chemical industry, petroleum, metallurgy, light industry, synthetic fiber, environmental protection, food, medicine and other departments. It has always been a technical problem to process the matching size and position of the ring hole of the pump. The traditional machining process is to use a boring machine to mill the shaft hole and the ring hole on one side to the drawing requirements, and then rotate the table 180° to mill the other side. It is difficult to ensure the concentricity requirements of the shaft holes on both sides and the mouth ring holes in such processing. At the same time, there are usually multiple annular holes in the pump body, and it is difficult to ensure the coaxiality of the multiple annular holes during repeated positio...
