Referring to fig. 1 and 2, in a preferred embodiment of the present invention, the dismounting tool 100 includes a bolt 110, a first nut 120, a second nut 130, a stop collar 140 and a distance collar 150. The attaching and detaching tool 100 according to the present embodiment is used for attaching a stud 200, and the stud 200 may be a full-thread stud or a stud. Wherein the threads of the bolt 110, the first nut 120, the second nut 130, and the stud 200 may all be right-handed threads.
Specifically, the bottom end of the bolt 110 is preferably configured as a circular arc surface to improve friction when the bottom of the bolt 110 contacts the stud 200. The first nut 120 is sleeved on the bolt 110, and the first nut 120 is in threaded connection with the bolt 110.
The second nut 130 is used for being in threaded fit with the stud 200 to be disassembled and assembled, and the second nut 130 is fixedly connected with the first nut 120 and is coaxial with the first nut. Specifically, the second nut 130 is coupled to the bottom end of the first nut 120, and the second nut 130 is preferably welded to the first nut 120. The inner diameter of the second nut 130 is larger than that of the first nut 120, the bottom end of the bolt 110 extends into the second nut 130, and the second nut 130 does not interfere with the bolt 110.
Referring now to fig. 2, a stop collar 140 is secured to the bolt 110 below the first nut 120. Preferably, the stop collar 140 is welded to the lower portion of the bolt 110. This arrangement can prevent the bottom end of the bolt 110 from being separated from the first nut 120. When the bolt 110 moves upward to a certain distance, the stop collar 140 can interfere with the first nut 120 to prevent the bolt 110 from moving further. In order that the second nut 130 does not interfere with the stop collar 140, the inner diameter of the second nut 130 is larger than the outer diameter of the stop collar 140.
Please continue to refer to fig. 1 and fig. 2. A distance sleeve 150 is arranged on the bolt 110 between the head of the bolt 110 and the first nut 120. Preferably, the distance sleeve 150 is welded to the bolt 110. The distance sleeve 150 serves to prevent the bottom of the bolt 110 from extending beyond the second nut 130. For this reason, the distance from the plane of the bottom end of the distance sleeve 150 to the plane of the bottom end of the shaft of the bolt 110 is smaller than the distance between the plane of the top end of the first nut 120 and the plane of the bottom end of the second nut 130. That is, the length of the shaft portion of the bolt 110 located below the distance sleeve 150 is smaller than the total height of the first and second nuts 120 and 130. Thus, when the bolt 110 moves down to a certain distance, the distance sleeve 150 can interfere with the first nut 120 to prevent the bolt 110 from moving further.
Preferably, the distance sleeve 150 and the position sleeve 140 cooperate to restrain the bottom end of the bolt 110 to the middle inside the second nut 130.
Furthermore, in an alternative embodiment, the bolt 110 is configured as a hex bolt, which may be used with a pneumatic wrench. The outer diameter of the distance sleeve 150 corresponds to the margin of the head of the hexagon bolt. That is, the cross section of the distance sleeve 150 is circular, and the cross section of the head of the hexagon bolt is a regular hexagon, which is an inscribed circle of the regular hexagon. Alternatively, the outer diameter of the distance sleeve 150 is equal to the pitch of the head of the hexagon bolt. From this, pneumatic wrench's sleeve can entangle hexagon bolt and distance cover 150 together, has increased telescopic effective effect length, and the lower part rocks when avoiding the sleeve rotation, has improved the stability when installing.
According to the disassembling tool 100 of the present invention, the bolt 110 can be driven to rotate forward by using the pneumatic wrench, so that the stud 200 to be disassembled is mounted on the workpiece 300, thereby facilitating the use of the torque fixing function of the pneumatic wrench; after the installation, the dismounting tool 100 can be separated from the stud 200 to be dismounted only by driving the bolt 110 to rotate reversely by the pneumatic wrench, so that the mounting operation of the stud 200 is convenient and efficient.
The detailed process of the mounting stud 200 of the dismounting tool 100 of the present invention is as follows:
when the stud 200 is in a state of being completely separated from the workpiece 300, one end of the stud 200 is screwed into the second nut 130 so as to be in contact with the bottom end of the bolt 110. The head of the bolt 110 is sleeved with the socket of the air wrench, and the air wrench is lifted to align the other end of the stud 200 with the threaded hole in the workpiece 300. The air wrench is rotated at a slow speed, at the moment, the sleeve drives the bolt 110 to rotate, the bottom end of the bolt 110 is tightly attached to the top end of the stud 200, the bolt 110 and the stud 200 are connected into a whole through the whole formed by the first nut 120 and the second nut 130, and the stud 200 rotates together with the bolt 110 until the stud 200 is screwed to the bottom of a threaded hole in the workpiece 300. The air pressure of the air wrench can then be adjusted to meet different torque requirements for stud 200 installation. After the installation, the pneumatic wrench is only required to be rotated reversely, the bolt 110 rotates reversely therewith and starts to move upwards until the limiting sleeve 140 abuts against the first nut 120, the bolt 110 drives the first nut 120 to rotate reversely together under the action of friction force, and then the second nut 130 rotates reversely to be separated from the stud 200.
The utility model discloses an improvement work efficiency that assembly and disassembly tools 100 can be by a wide margin when installing double-screw bolt 200 reduces intensity of labour, low in manufacturing cost, and can satisfy different torsion demands with the help of air wrench, has obvious advantage.
When the stud 200 is partially located in the threaded hole of the workpiece 300, the head of the bolt 110 is sleeved with the sleeve of the pneumatic wrench, the pneumatic wrench is lifted up, the second nut 130 is sleeved on the top end of the stud 200, the second nut 130 is rotated to enable the stud 200 to enter the second nut 130, the pneumatic wrench rotates forward to start screwing, the subsequent process is similar to the above process, and details are not repeated.
In another preferred embodiment of the present invention, the disassembly and assembly tool 100 is used to disassemble the stud 200. Wherein the threads of the bolt 110 and the first nut 120 may be configured as left-hand threads and the threads of the second nut 130 and the stud 200 may be generally right-hand threads. The detailed process of disassembling the stud 200 is as follows:
sleeving the sleeve of the air wrench on the head of the bolt 110, lifting the air wrench to sleeve the second nut 130 on the top end of the stud 200, rotating the second nut 130 to enable the stud 200 to enter the second nut 130, and enabling the stud 200 to abut against the bottom end of the bolt 110. The integration of the first nut 120 and the second nut 130 connects the bolt 110 and the stud 200 as a single body. Then, the pneumatic wrench is operated to rotate reversely, the bolt 110 drives the stud 200 to rotate reversely, and the stud 200 can be unscrewed.
