Detailed ways

The preferred embodiments of the utility model will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the utility model can be more easily understood by those skilled in the art, so that the protection scope of the utility model can be defined more clearly.

Please refer to accompanying drawing 1 to Fig. 2, the utility model embodiment comprises:

A stud bolt assembly and disassembly tool includes a stud bolt 7. The stud bolt assembly and disassembly tool includes a lead screw 1, a lead screw wrench 4, a sleeve 2, a socket wrench 5 and a nut 3. The lead screw wrench 4 vertically passes through the hole at the upper end of the lead screw 1, the lower part of the lead screw 1 passes through the hole in the middle of the sleeve 2, and is threadedly connected with the sleeve 2, and the sleeve 2 is provided on both sides with the sleeve 2. Vertical socket wrench 5, the lower end of the sleeve 2 extends into the upper end of the nut 3, the nut 3 and the sleeve 2 are fixed by the fastening screws 6 on both sides, the upper part of the stud bolt 7 passes through the nut 3, and is connected with the nut 3 Threaded connection, the upper end surface of the stud bolt 7 is in close contact with the lower end surface of the lead screw 1. By rotating the lead screw 1, the lower end surface of the lead screw 1 and the upper end surface of the stud bolt 7 generate frictional force to drive the stud bolt 7 to rotate. The lead screw 1 is connected with the sleeve 2 with a left-hand fine thread. The nuts 3 are produced in series according to thread standards to meet the matching requirements of different stud bolts.

The specific operation steps are:

Install the stud bolt: select the nut 3 to be consistent with the thread specification of the stud bolt 7 to be installed, tighten the connection with the sleeve 2 through the set screw 6, rotate the lead screw wrench 4, adjust the height of the lead screw 1, and insert the stud bolt 7 Screw in the nut 3 until the upper end surface of the stud bolt 7 is in contact with the lower end surface of the lead screw 1, hold the socket wrench 5 tightly, align with the internal threaded hole at the installation position and rotate clockwise, and use the contact between the stud bolt 7 and the end surface of the lead screw 1. Friction, realize the installation of stud bolt 7.

Remove the stud bolts: select the nut 3 to be consistent with the thread specification of the stud bolt 7 to be installed, tighten the connection with the sleeve 2 through the set screw 6, rotate the lead screw wrench 4, adjust the height of the lead screw 1, and hold the socket wrench tightly 5. Align the nut 3 hole with the stud bolt 7 to be removed and screw it clockwise until the upper end surface of the stud bolt 7 contacts the lower end surface of the lead screw 1, hold the lead screw wrench 4 and rotate it counterclockwise, and the lead screw 1 will drop , The end surface of the lower part of the leading screw tightly presses the upper end surface of the stud bolt 7, and friction is generated to drive the stud bolt 7 to rotate counterclockwise until it is unscrewed, and the disassembly of the stud bolt 7 is completed.
