[0031] An assembly tool 100 for a torque ring is provided in an embodiment of the present utility model. The assembly tool 100 is used to install a torque ring 40 sleeved with an O-ring 50 into a bracket 60 having a mounting hole.
[0032] Specifically, the assembly tool 100 includes a base 10, a sleeve 20, and a pressing plate 30. Among them, the base 10 has a working surface for fixing the bracket 60; the sleeve 20 has a through hole with a diameter consistent with that of the mounting hole; the lower end of the sleeve 20 is placed on the bracket 60, and the upper end of the sleeve 20 is used to place the torque ring 40, and the through hole, the torque ring 40, and the mounting hole are aligned; the pressing plate 30 is arranged above the sleeve 20 and is used to press-fit the torque ring 40 into the mounting hole of the bracket 60 through the sleeve 20.
[0033] The torque ring 40 has a cylindrical structure, and along the axial direction of the cylindrical structure, at least one limiting groove is provided on its outer periphery. The O-ring 50 is sleeved on the torque ring 40 and is specifically arranged in the limiting groove. A mounting hole with a diameter consistent with that of the torque ring 40 is formed on the bracket 60. The torque ring 40 is inserted into the mounting hole of the bracket 60 and is fixedly and sealingly connected to the bracket 60 through the O-ring 50.
[0034] In the assembly tooling 100, the base 10 is used to fix the bracket 60, so that one end of the bracket 60 for installing the torque ring 40 is arranged upward. The sleeve 20 is placed at the upper end of the bracket 60, and the central axis of the through hole of the sleeve 20 is aligned with the central axis of the mounting hole in the bracket 60. The torque ring 40 is placed above the sleeve 20, and the central axis of the torque ring 40 is aligned with the central axis of the sleeve 20. Then, pressure is applied to the torque ring 40 through the pressing plate 30, and thus the torque ring 40 is pressed into the mounting hole of the bracket 60 through the sleeve 20. During the pressing process, the torque ring 40 first passes through the sleeve 20, and the O-ring 50 sleeved thereon enters the sleeve 20 completely in a flattened state and maintains this state, and then enters the mounting hole of the bracket 60 until the installation is in place.
[0035] The assembly tooling 100 for the torque ring provided by the embodiment of the present utility model fixes the bracket 60 with a mounting hole by setting the base 10, applies pressure to the torque ring 40 through the pressing plate 30 to press the torque ring 40 into the mounting hole, and at the same time, sets the sleeve 20 to flatten the O-ring 50 and makes the O-ring 50 maintain the flattened state during the whole pressing process until the installation is in place. In this way, not only can the situation that the O-ring 50 is extruded from the mounting hole during assembly be avoided, but also the wear of the O-ring 50 can be reduced, thereby improving the service life of the O-ring 50, indirectly improving the service life of the product, and reducing the quality problems caused by the damage of the O-ring 50.
[0036] In one embodiment, a chamfer or a fillet is formed at the upper end of the sleeve 20, and the chamfer or the fillet is used to reduce the resistance of the O-ring 50. Specifically, by setting the chamfer or the fillet, the resistance when the O-ring 50 enters the sleeve 20 can be reduced, and thus the initial friction force when entering the sleeve 20 can be reduced, and the wear of the O-ring 50 can be reduced, thereby avoiding the wear caused by reasons such as a small chamfer at the orifice of the mounting hole of the bracket 60. Moreover, the above structure is simple and has wide practicability. Preferably, by setting the chamfer or the fillet, the diameter at the orifice position of the upper end of the sleeve 20 is larger than the diameter at the position where the O-ring 50 is sleeved on the torque ring 40.
[0037] In one embodiment, the pressing plate 30 is arranged in a T shape and includes a pressing part 31 and a pressing force applying part 32. The pressing force applying part 32 is used to connect with an external force applying mechanism, one end of the pressing part 31 is connected to the center of the pressing force applying part 32, and the other end is used to press the torque ring 40.
[0038] By setting the pressing part 31 corresponding to the torque ring 40 and the pressing force applying part 32 corresponding to the external force applying mechanism, the size of the pressing part 31 can be adjusted according to the size of the torque ring 40, and the size of the pressing force applying part 32 can be adjusted according to the size of the external force applying mechanism. In this way, the acting force applied by the external force applying mechanism can be better transmitted to the torque ring 40, so as to realize the pressing work of the torque ring 40.
[0039] In one embodiment, a blind hole is formed at one end of the pressing portion 31 facing away from the pressing part 32. Specifically, the pressing portion 31 is arranged in a hollow column shape. In this way, the acting force applied by the pressing portion 31 to the torque ring 40 is evenly distributed on the outer periphery of the end face of the torque ring 40, so that the circumferential direction of the torque ring 40 can be synchronously pressed down into the through hole and the mounting hole, thereby avoiding the problem of serious local wear of the O-ring 50 due to uneven force; at the same time, by providing the blind hole, other structures on the torque ring 40 can also be avoided.
[0040] In one embodiment, the diameter of the pressing portion 31 is smaller than the diameter of the through hole. In this way, the pressing portion 31 can be inserted into the through hole of the sleeve 20 and apply pressure to the torque ring 40.
[0041] In one embodiment, the axial length of the pressing portion 31 is greater than the axial length of the sleeve 20. In this way, the pressing portion 31 can be inserted into the through hole of the sleeve 20 and apply pressure to the torque ring 40.
[0042] In one embodiment, the pressing part 32 includes a flat plate 33 and a reinforcing ring 34. The upper end of the pressing portion 31 is connected to the center of the flat plate 33, and the reinforcing ring 34 is arranged along the outer periphery of the lower side of the flat plate 33. By providing the reinforcing ring 34, on the one hand, it is convenient to enhance the structural strength of the pressing part 32 and reduce the deformation rate of the pressing part 32, and on the other hand, it is convenient for the external force application mechanism to be connected to the pressing part 32, thereby improving the connection strength between the external force application mechanism and the pressing part 32.
[0043] In one embodiment, the pressing part 32 further includes an indicating member 25 for indicating the limit pressing position. In this way, it can be prompted that the torque ring 40 is assembled in place, thereby avoiding over-assembly.
[0044] In one embodiment, an avoidance groove is formed on the sleeve 20 for avoiding the radially protruding portion 41 of the torque ring 40. By providing an avoidance groove corresponding to the radially protruding portion 41 of the torque ring 40 on the sleeve 20, the torque ring 40 can pass through the sleeve 20 smoothly and be assembled into the mounting hole.
[0045] The embodiment of the present utility model also provides an assembling device, and the assembling device includes the assembling tooling 100 for the torque ring in any one of the above.
[0046] Specifically, the assembly device not only includes the above-mentioned assembly tooling 100, but may also include an installation table, a corresponding workbench, a force application mechanism, and a loading and unloading mechanism. Among them, the base 10 can be arranged on the workbench, the force application mechanism is connected to the pressing plate 30, and the loading and unloading mechanism can be used for the loading and unloading operations of the bracket 60, the torque ring 40, and the sleeve 20. The assembly tooling 100 realizes the assembly of the torque ring 40 and the bracket 60 by cooperating with the workbench, the force application mechanism, and the loading and unloading mechanism.
[0047] In the embodiment of the present invention, the assembly device refers to the above-mentioned embodiment. Since the assembly device provided by the embodiment of the present invention has all the technical features of the above-mentioned assembly tooling 100 for the torque ring, it also has at least the beneficial effects of all the above-mentioned embodiments, which will not be elaborated here one by one.
[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
