The countersunk head high lock nut unscrewing tool according to the embodiment of the invention is described below with reference to fig. 1 to 4.
As shown in fig. 1, according to the utility model discloses countersunk head high lock nut twists takes off frock, include: the countersunk head mounting sleeve 100 is of a hollow structure, countersunk holes 110 matched with countersunk head angles of the countersunk head high-locking nuts are formed in the upper end and the lower end of the countersunk head mounting sleeve 100, the lower end of the countersunk head mounting sleeve 100 is used for mounting test bolts, and the test bolts penetrate through the countersunk head mounting sleeve 100 and are connected with the countersunk head high-locking nuts; at least two adjusting bolts 300, each adjusting bolt 300 sets up respectively on countersunk head installation sleeve 100 and be in same horizontal plane, and each adjusting bolt 300 is along horizontal direction and countersunk head installation sleeve 100 threaded connection.
As shown in fig. 1, in an embodiment of the present invention, the number of the adjusting bolts 300 is two, the two adjusting bolts 300 are located in different directions, and the adjusting bolts 300 are connected to the countersunk head mounting sleeve 100 by threads. According to the needs of the test, through adjusting two adjusting bolt 300, can provide the transverse force of certain direction for the high lock nut of countersunk head, the size and the direction accessible of transverse force two adjusting bolt 300's rotating displacement come control, convenient operation and test result are accurate.
As shown in fig. 3, in another embodiment of the present invention, the number of the adjusting bolts 300 is three, and three adjusting bolts 300 are disposed on the countersunk head mounting sleeve 100 in a circumferentially uniform manner. Through adjusting three adjusting bolt 300, can provide the transverse force of certain direction for the high lock nut of countersunk head according to the test needs, the size and the direction of transverse force are controlled by three adjusting bolt 300's rotating displacement jointly, and the control range is bigger.
As shown in fig. 4, in a further embodiment of the present invention, the number of the adjusting bolts 300 is four, and four adjusting bolts 300 are placed on the countersunk head mounting sleeve 100 in a circumferentially uniform manner. Therefore, the adjusting bolts 300 can be adjusted from four different directions, the transverse force in a specific direction and a specific size can be provided by adjusting the rotating displacement of each adjusting bolt 300 respectively, the operation is convenient, the installation and use environment of the countersunk high-locking nut is accurately simulated, and the test result can be closer to the real situation. It is conceivable that the number of the adjusting bolts 300 may be 5, 6, 7, etc., without being limited thereto, and those skilled in the art may set them according to actual circumstances.
In some implementations of the present invention, a reticle 400 is also included. As shown in fig. 2, the number of rulers 400 is the same as the number of adjustment bolts 300, and each ruler 400 is provided on the countersunk head mounting sleeve 100 and positioned directly above or below the corresponding adjustment bolt 300. By arranging the reticle 400, the rotating displacement of the adjusting bolt 300 can be observed conveniently, so that the transverse force can be accurately controlled by controlling the rotating displacement of the adjusting bolt 300, and the test result is accurate.
In some implementations of the present invention, the reticle ruler 400 is fixedly connected to the countersunk head mounting sleeve 100, and the fixing method can adopt common methods such as welding or riveting, which facilitates reading.
The utility model discloses an in some implementations, groove chi 400 can be dismantled with countersunk head installation sleeve 100 and be connected, and the connected mode can adopt key-type connection or common modes such as buckle connection, can dismantle the connected mode and be known by the personnel in the field, and it is no longer repeated this time. Set up convenient to detach groove chi 400 like this, because adjusting bolt 300 is threaded connection with countersunk head installation sleeve 100, so adjusting bolt 300 and groove chi 400 all can be dismantled, make like this according to the utility model discloses countersunk head high lock nut twists and takes off the frock and conveniently carries.
In some implementations of the present invention, the reticle 400 has a scale facing the corresponding adjusting bolt 300, so that the user can easily see the rotating displacement of the adjusting bolt 300 when adjusting the adjusting bolt 300, which is convenient for operation.
Referring to fig. 5 and 6, it can be seen that the angle of the counter bore 110 is α, which can be the usual 90 °, 100 °, or 120 °, but also other angles, only 0 ° < α <180 °. The angle of the counter bore 110 is determined according to the counter angle of the counter top lock nut.
Referring to fig. 7, it can be seen that the adjuster bolt 300 includes a head portion 310 and a shank portion 320, the head portion 310 being located outside of the counter-sunk mounting sleeve 100 and the shank portion 320 passing through a threaded bore in the counter-sunk mounting sleeve 100. When the pretightening force is tested, the adjusting bolt 300 is screwed in according to the test requirement, and a transverse force in a certain direction is provided. When the loosening force is tested, the adjusting bolt 300 can be screwed out to remove the transverse force.
Before the pre-tightening force of the countersunk head high-locking nut is tested, the testing bolt penetrates through the countersunk head mounting sleeve 100 from the lower end of the countersunk head mounting sleeve 100 and then is connected with the countersunk head high-locking nut, and after the countersunk head high-locking nut is screwed down, the adjusting bolt 300 is adjusted. The transverse force in a certain direction can be given to the countersunk head high lock nut by adjusting the adjusting bolt 300, and the rotating displacement of the adjusting bolt 300 can be read out through the reticle 400, so that an accurate transverse force can be provided according to the test requirement, and the pretightening force test can be carried out by using a testing device. After the pretightening force test is finished, a loosening force test is carried out, the adjusting bolt 300 is rotated outwards, so that the transverse force can be removed, and the testing device can be used for the loosening force test.
According to the utility model discloses a frock is twisted off to high lock nut of countersunk head, the accurate installation service environment who has simulated the high lock nut of countersunk head, only with one set of frock alright regard as the pretightning force of the high lock nut of countersunk head and the test device of pine loosening force, convenient operation, efficiency of software testing and measuring accuracy height.
