Description

Technical Field

[0001] The utility model relates to the technical field of vertical split case pump processing, in particular to a boring cutter device for a vertical split case pump. Background Art

[0002] Compared with other similar pumps, vertical split case pumps have the characteristics of long life, high efficiency, reasonable structure, low operating cost, convenient installation and maintenance, etc. They are ideal pumps for fire protection, air conditioning, chemical industry, water treatment and other industries.

[0003] In order to ensure the use effect and service life of the pump body, the coaxiality of the pump body sealing ring hole is required to be high. The sealing ring hole of the traditional vertical split pump is bored by installing a long boring tool on the spindle of the boring machine. When using this boring method, there are the following problems:

[0004] When the boring machine uses a long boring tool to bore holes, after boring the sealing ring hole on one side, the pump body needs to be adjusted and rotated 180° before boring the sealing ring hole on the other side. After the pump body is rotated, it needs to be repositioned. This process will affect the coaxiality of the sealing ring holes on the left and right sides of the vertical split pump due to positioning errors.

[0005] In order to improve the accuracy of the sealing ring hole, rough machining is required first, and then fine machining is performed; this process requires separating the pump cover from the pump body, adjusting the cutting depth, and then installing the pump cover and the pump body together for fine machining; after the sealing ring hole on one side is machined, the pump body is adjusted and rotated 180° to machine the sealing ring hole on the other side, causing the above-mentioned process of opening the pump cover to be doubled, and the machining efficiency is low.

[0006] When the spindle is used to install a long boring tool, due to the long length of the boring tool bar, the boring tool bar is prone to vibrate when boring, resulting in low machining accuracy and large errors. Utility Model Content

[0007] In view of the above-mentioned shortcomings, the utility model provides a boring tool device for a vertical split-center pump.

[0008] The utility model is realized through the following technical scheme: a boring tool device for a vertical split pump, comprising a boring bar and a boring tool disc, a tapered handle is provided at one end of the boring bar, a tailstock fixing sleeve is provided at the other end, a boring tool disc hole is provided on the boring tool disc, the boring tool disc is arranged on the boring bar through the boring tool disc hole sleeve, a boring tool is provided on the boring tool disc, and the boring tool is arranged at both ends of the boring tool disc perpendicular to the axis of the boring tool disc.

[0009] Furthermore, the boring tool is movably mounted on the boring tool disc through the boring tool mounting groove.

[0010] Furthermore, the boring tool can adjust the extension length of the boring tool relative to the boring tool disc through the boring tool mounting groove.

[0011] Furthermore, the number of boring tools at both ends of the boring tool disc is one or more.

[0012] The beneficial effects that the utility model can bring are:

[0013] 1. The utility model arranges a boring bar between the taper shank hole of the boring machine and the tailstock of the boring machine, and sleeves a boring cutter disc on the outer side of the boring bar. After processing the sealing ring hole on one side, the main shaft of the boring machine drives the adjusting boring bar and the boring cutter disc sleeved on the outer side of the boring bar to move along the central axis direction of the sealing ring hole of the vertical split center pump to the sealing ring hole to be processed on the other side, so as to process the sealing ring hole on the other side. The boring hole can be completed without turning and repositioning the pump body, thereby avoiding the error caused by the secondary positioning of the pump body, improving the coaxiality of the sealing ring holes on both sides of the vertical split center pump, and improving the processing efficiency.

[0014] 2. The utility model replaces the method of installing a long boring tool on the spindle by arranging the boring tool on the boring tool disc, thereby solving the problems of low machining accuracy and large errors caused by the vibration of the long boring tool during machining.
