Description

Technical Field

[0001] The present invention relates to the technical field of bolts, and particularly to a disassembly and assembly device for a double-ear locking washer and a stop disassembly and assembly mechanism. Background Art

[0002] Double-ear locking washers are widely used in the anti-loosening design of threaded connectors due to their simple operation, reliable anti-loosening performance, and low manufacturing cost. During assembly, the double-ear locking washer is fixed against loosening by bending the locking tail or abutting against the mounting edge and making the locking tip abut against the edge of the hexagon head bolt. During disassembly, it mainly relies on chiseling the contact part between the locking tip of the locking washer and the edge of the bolt to separate the two, thereby releasing the anti-loosening state of the bolt.

[0003] Most of the existing tools for installing and disassembling double-ear locking washers are of a split design. During disassembly, the disassembly tool needs to be removed, and during installation, the installation tool needs to be used again, which is not convenient for carrying and using. At the same time, when the existing double-ear locking washer is disassembled, since it is necessary to chisel the contact part between the locking tip of the locking washer and the edge of the bolt, it is easy to cause knocking damage to the bolt and the connected object.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] In the description of the embodiments of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the embodiments of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the embodiments of the present invention. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0035] Next, in combination with Figures 1 to 4 , the present invention provides a stop disassembly and assembly mechanism, including a double-ear stop washer 20 and a disassembly and assembly device for the double-ear stop washer. That is, the two ears of the double-ear stop washer 20 are bent through the disassembly and assembly device of the double-ear stop washer, so as to limit the position of the bolt 30. It should be noted that the double-ear stop washer 20 includes a mating hole 230, a first ear 210, and a second ear 220. The mating hole 230 is used to mate with the bolt 30 to be disassembled and assembled. The double-ear stop washer 20 includes a first disassembly and assembly plate 120 and a second disassembly and assembly plate 130. The first disassembly and assembly plate 120 cooperates with the first ear 210, and thus the first ear 210 can be bent. That is, the first ear 210 can be bent by the first disassembly and assembly plate 120 to abut against the head of the bolt 30 to limit the position of the bolt 30. When the bolt 30 needs to be disassembled, the first disassembly and assembly plate 120 can cooperate with the first ear 210 to be bent in the opposite direction to eliminate the limit. Similarly, the second disassembly and assembly plate 130 can cooperate with the second ear 220 to be bent. The bending direction of the second ear 220 is opposite to that of the first ear 210, and is used to abut against the end face of a connecting member such as a flange below the bolt 30 to increase the force on the first ear 210, and thus improve the stopping effect of the double-ear stop washer 20 on the bolt 30.

[0036] In an embodiment of the present invention, an included angle is set between the first ear portion 210 and the second ear portion 220 of the double-ear stop washer 20. Preferably, the first ear portion 210 and the second ear portion 220 are perpendicularly arranged. The first disassembly and assembly plate 120 is a matching thin plate. The second disassembly and assembly plate 130 is a cylindrical grip rod, and a plate hole 1310 is formed in the second disassembly and assembly plate 130.

[0037] Please refer to Figure 4 and Figure 5 , during the actual disassembly and assembly process, a pressing plate groove 2110 that cooperates with the first disassembly and assembly plate 120 is formed in the first ear portion 210 of the double-ear stop washer 20. Thus, the first disassembly and assembly plate 120 is inserted into the pressing plate groove 2110, and then the first ear portion 210 is bent with the second disassembly and assembly plate 130 as the force application end. Similarly, the outer peripheral dimension of the second ear portion 220 corresponds to the dimension of the plate hole 1310 of the second disassembly and assembly plate 130. Thus, the first disassembly and assembly plate 120 can be used as the force application end to bend the second ear portion 220.

[0038] Specifically, the disassembly and assembly device of the double-ear stop washer further includes a disassembly and assembly main body 10 connected to the first disassembly and assembly plate 120 and the second disassembly and assembly plate 130 respectively. The cross-sectional dimension of the first disassembly and assembly plate 120 decreases along the extending direction away from the disassembly and assembly main body 10. Similarly, a pressing plate groove 2110 is formed in the first ear portion 210, and the cross-sectional dimension of the pressing plate groove 2110 increases along the matching direction of the first ear portion 210 and the first disassembly and assembly plate 120.

[0039] That is, when the first disassembly and assembly plate 120 is fitted towards the pressing plate groove 2110, the end with the smallest cross-sectional dimension of the first disassembly and assembly plate 120 abuts against the end with the largest cross-sectional dimension of the pressing plate groove 2110. As it extends into the pressing plate groove 2110, the connection between the first disassembly and assembly plate 120 and the first ear portion 210 will become tighter and tighter. On the one hand, it can avoid the rigid impact between the end of the first disassembly and assembly plate 120 and the first ear portion 210 when the first disassembly and assembly plate 120 cooperates with the first ear portion 210, and prevent the components on the periphery of the pressing plate groove 2110 of the first ear portion 210 from being worn. On the other hand, because both the pressing plate groove 2110 and the first disassembly and assembly plate 120 are arranged with decreasing or increasing cross-sections, the space inside the pressing plate groove 2110 will not be enlarged during the cooperation process between the first disassembly and assembly plate 120 and the pressing plate groove 2110.

[0040] Please refer to Figure 6, because when the first disassembly and assembly plate 120 is engaged with the pressing plate groove 2110 and bends the first ear portion 210, the end of the first disassembly and assembly plate 120 extending into the pressing plate groove 2110 will form an abutment with the circumferential side wall of the pressing plate groove 2110 to receive force. During the process of the first disassembly and assembly plate 120 applying force and the pressing plate groove 2110 receiving force, it is inevitable that the internal space of the pressing plate groove 2110 becomes larger. For example, when the first disassembly and assembly plate 120 abuts against the inside of the pressing plate groove 2110 multiple times, a recessed space 2120 will be formed at the position where the first disassembly and assembly plate 120 abuts against the inside of the pressing plate groove 2110 multiple times. As a result, when the first disassembly and assembly plate 120 bends the first ear portion 210, the first ear portion 210 cannot reach the bending position, which seriously affects the position limitation of the first ear portion 210 on the connecting object such as the bolt 30. When the first ear portion 210 does not reach the abutting position with the bolt 30, the operator will increase the force, which further enlarges the recessed space 2120. Repeating this process will seriously damage the use of the first ear portion 210.

[0041] Specifically, as Figure 6 shown, point P is the force-receiving point where the first disassembly and assembly plate 120 abuts against the first ear portion 210. During the long-term pressing process of the first disassembly and assembly plate 120, a recessed space 2120 will slowly form at point P, and the size of the recessed space 2120 will become larger and larger. As a result, initially, the first disassembly and assembly plate 120 can make the first ear portion 210 in the position of C1. However, as the size of the recessed space 2120 increases, the termination limiting position of the first ear portion 210 has a tendency to move in the direction from the initial position C1 to the changing position C2, and thus the end face of the first ear portion 210 cannot be fitted to the head of the bolt 30, and the limiting effect on the bolt 30 is greatly reduced.

[0042] In the embodiment of the present application, the first disassembly and assembly plate 120 is a thin plate. Therefore, when the first disassembly and assembly plate 120 forms an abutment with the pressing plate groove 2110, the circumferential side of the first disassembly and assembly plate 120 abuts against the pressing plate groove 2110 evenly, and the force is not concentrated at the end of the first disassembly and assembly plate 120. Thus, the force intensity of the first disassembly and assembly plate 120 on the pressing plate groove 2110 can be reduced to protect the first ear portion 210, and the service life of the first ear portion 210 is improved.

[0043] In an embodiment of the present invention, the second disassembly and assembly plate 130 is provided with a plate hole 1310 from one end face far away from the disassembly and assembly main body 10 along the direction towards the disassembly and assembly main body 10. The second disassembly and assembly plate 130 can be sleeved on the second ear portion 220. Thus, during the process of bending the second ear portion 220, the outer periphery of the second ear portion 220 will not be worn, and the service life of the second ear portion 220 is improved.

[0044] The disassembly and assembly main body 10 further includes a force-bearing mounting member 110, and both the first disassembly and assembly plate 120 and the second disassembly and assembly plate 130 are connected to the force-bearing mounting member 110 and are arranged oppositely. Further, the force-bearing mounting member 110 includes a first protruding side 1110 and a second protruding side 1120 arranged oppositely to the first protruding side 1110; the connecting end of the first disassembly and assembly plate 120 and the force-bearing mounting member 110 is arranged close to the first protruding side 1110, and the connecting end of the second disassembly and assembly plate 130 and the force-bearing mounting member 110 is arranged close to the second protruding side 1120.

[0045] It should be noted that the first disassembly and assembly plate 120 and the second disassembly and assembly plate 130 are arranged relative to the force-bearing mounting member 110, and the connecting ends of the first disassembly and assembly plate 120 and the second disassembly and assembly plate 130 and the force-bearing mounting member 110 are respectively arranged close to the opposite two ends of the force-bearing mounting member 110. Thus, when the first disassembly and assembly plate 120 cooperates with the first ear portion 210 and the second disassembly and assembly plate 130 is the force-applying end, the end of the first disassembly and assembly plate 120 far from the first disassembly and assembly plate 120 has a longer distance. Based on the lever principle, the second disassembly and assembly plate 130 is more labor-saving in the force-applying state.

[0046] The included angle is set between the end face of the first protruding side 1110 facing the first disassembly and assembly plate 120 and the end face of the first disassembly and assembly plate 120 facing the first protruding side 1110 to form an avoidance space 1130. In an embodiment of the present invention, the included angle is at least greater than 90 degrees. Thus, when the first ear portion 210 is bent, the first protruding side 1110 can form an avoidance space 1130 to prevent the first ear portion 210 from hitting the bolt 30 during the bending process.

[0047] In summary, for the disassembly and assembly device of the double-ear locking washer provided by the present invention, the first disassembly and assembly plate 120 is used to bend the first ear portion 210 of the double-ear locking washer 20, and the second disassembly and assembly plate 130 is used to bend the second ear portion 220 of the double-ear locking washer 20, that is, the bending conditions of the first ear portion 210 and the second ear portion 220 of the double-ear locking washer 20 can be controlled through the first disassembly and assembly plate 120. The first ear portion 210 and the second ear portion 220 of the double-ear locking washer 20 can make the bolt 30 in a locking state and an unlocking state. Thus, the double-ear locking washer 20 can be controlled through the disassembly and assembly main body 10, simplifying the disassembly and assembly process of the double-ear locking washer 20 and not causing wear to the surfaces of connecting objects such as the bolt 30.
