The condition of repairing the sleeve hole of the temperature sensor occasionally occurs in the machining process, the mechanical machining process is limited by the structural form of the stator end socket, the bottom of the sleeve hole of the temperature sensor is a closed ring groove, and the nuclear power project requires that foreign matters are not allowed to enter, so that a new plugging tool needs to be designed and manufactured, the repair work can be completed, and the foreign matters are prevented from entering the closed ring groove of the stator end socket.
The utility model content is as follows:
the utility model aims to provide a large-scale shielding motor stator end socket temperature sensor sleeve hole processing and plugging tool which can effectively prevent cutting fluid and scrap iron from entering the inside of a closed ring groove, and ensure the processing quality of the large-scale shielding motor stator end socket temperature sensor sleeve hole and the cleanness of the inside of the closed ring groove of a shielding motor product stator end socket.
The utility model adopts the following technical scheme: the utility model provides a large-scale canned motor stator head temperature sensor sleeve pipe spot facing work shutoff instrument, by pull ring (1), support nut (2), shutoff silica gel (3), threaded rod (4) and bracing piece (5) are constituteed, pull ring (1) welded fastening is in threaded rod (4) one end, shutoff silica gel (3) are fixed on threaded rod (4) by two support nut (2), shutoff silica gel (3) excircle has the tapering, threaded rod (4) other end has bracing piece (5) that form with threaded rod (4) integrated into one piece.
The working principle of the utility model is as follows:
when a threaded hole (9) at the front end of a temperature sensor sleeve hole (8) of a stator end socket (6) is reworked by a machine, the tool is placed into the temperature sensor sleeve hole (8), so that cutting fluid and scrap iron can be effectively prevented from entering a sealing ring groove (7) of the stator end socket (6), and the tool can be smoothly taken out through a pull ring (1) after the reworked threaded hole (9) is finished.
Can effectively prevent cutting fluid and scrap iron from entering the closed ring groove (7). The outer diameter of the supporting nut (2) is determined according to the inner diameter of the temperature sensor sleeve hole (8), so that the tool is horizontal after being placed in the temperature sensor sleeve hole (8), and the auxiliary plugging silica gel (3) prevents cutting fluid and scrap iron from entering the closed ring groove (7).
The tool is arranged in a temperature sensor sleeve hole (8) of a stator seal head (6). The plugging silica gel (3) is fixed on a certain position of the threaded rod (4) by two supporting nuts (2), the diameter of the plugging silica gel (3) and the taper of the excircle are determined according to the inner diameter of the sleeve hole (8) of the temperature sensor, and cutting fluid and scrap iron can be effectively prevented from entering the closed ring groove (7). The outer diameter of the supporting nut (2) is determined according to the inner diameter of the temperature sensor sleeve hole (8), so that the tool is horizontal after being placed in the temperature sensor sleeve hole (8), and the auxiliary plugging silica gel (3) prevents cutting fluid and scrap iron from entering the closed ring groove (7).
The specific working process of the utility model can refer to the following examples: before the sleeve hole (8) of the temperature sensor is repaired, the tool is arranged in the hole and pushed into the wall of the closed ring groove (7). And (3) starting to repair a threaded hole (9) at the front end of the sleeve hole (8) of the temperature sensor, using a cutter to cooperate with cutting fluid to repair, and pulling the pull ring (1) to pull out the tool after the repair is finished.
The utility model has the advantages that:
the key of the device is that the diameter of the support nut (2) is determined by the inner diameter of the sleeve hole (8) of the temperature sensor, so that the whole tool can be supported to be horizontal to assist in plugging the silica gel (3); the diameter and the outer diameter taper of the plugging silica gel (3) are determined by the inner diameter of the sleeve hole (8) of the temperature sensor, so that cutting fluid and scrap iron can be effectively prevented from entering the inside of the closed ring groove (7); the length dimension of the support rod (5) is determined by the dimension of the closed ring groove (7), so that the tool can be prevented from falling into the closed ring groove (7) due to the resistance of cutting fluid.
When the threaded hole (9) at the front end of the sleeve hole (8) of the temperature sensor is repaired, the plugging tool can effectively prevent foreign matters from entering the closed ring groove (7) of the stator end socket, can be freely installed in the sleeve hole (8) of the temperature sensor and can also be freely pulled out, and provides basis and experience for repair work of the same type of shielding motor products.
