[0031] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0032] The following is combined with Figure 2-3 This application is described in further detail.

[0033] The embodiment of the present application discloses a positioning fixture.

[0034] Reference Figure 2 and Figure 3 The positioning fixture includes a positioning seat 1, and a placement groove 2 is provided on the upper side of the positioning seat 1. The shape of the placement groove 2 matches the shape of the special-shaped tube 10, so as to place the special-shaped tube 10. The positioning seat 1 is provided with a first positioning line 3 at one end of the placement groove 2. The first positioning line 3 is connected to the placement groove 2 and is used to position the end of the special-shaped tube 10 away from the incision 102. The positioning seat 1 is also provided with a positioning groove 4 at the middle part of the placement groove 2. The positioning groove 4 is connected to the placement groove 2 and is used to position the rubber sleeve 11.

[0035] In actual application, the staff first puts the rubber sleeve 11 on the special-shaped tube 10, and moves the rubber sleeve 11 to the middle position of the special-shaped tube 10 so that the rubber sleeve 11 is in an approximate bonding position, and then places the rubber sleeve 11 in the positioning groove 4. At this time, the position of the special-shaped tube 10 is moved according to the actual situation, so that the end of the special-shaped tube 10 away from the incision 102 is aligned with the first positioning line 3, and then a small amount of glue is dripped between the rubber sleeve 11 and the special-shaped tube 10 for pre-fixation, and finally the glue is taken out and dripped between the rubber sleeve 11 and the special-shaped tube 10 to achieve the rubber sleeve 11 Bonded and fixed to the special-shaped tube 10. In this process, the rubber sleeve 11 can be guaranteed to be in the correct bonding position as much as possible, thereby improving the fixing accuracy of the rubber sleeve 11, and the structure is simple and easy to operate.

[0036] In some embodiments, there is a gap between the bottom wall of the positioning groove 4 and the rubber sleeve 11. Specifically, there is a gap between the bottom wall of the positioning groove 4 and the lowest point of the rubber sleeve 11 to facilitate relative displacement between the special-shaped tube 10 and the rubber sleeve 11, thereby facilitating adjustment of the bonding and fixing position of the rubber sleeve 11 to improve the fixing accuracy of the rubber sleeve 11.

[0037] In some embodiments, the length of the positioning groove 4 is greater than the diameter of the rubber sleeve 11, so as to facilitate the removal of the special-shaped tube 10 and the rubber sleeve 11 from the positioning groove 4, and also facilitate the dripping of glue between the special-shaped tube 10 and the rubber sleeve 11, so as to facilitate the pre-fixation of the rubber sleeve 11.

[0038] In some embodiments, a first protrusion 5 is formed on the positioning seat 1, and the first protrusion 5 is arranged in a right-angled trapezoidal block shape. One end of the placement groove 2 is arranged on the first protrusion 5, so that one end of the special-shaped tube 10 is placed on the first protrusion 5. In this embodiment, the end of the special-shaped tube 10 away from the incision 102 is placed on the first protrusion 5, so that the end of the special-shaped tube 10 away from the incision 102 can be accurately and smoothly placed in the placement groove 2, and the special-shaped tube 10 partially protrudes from the placement groove 2, so as to facilitate the placement and removal of the special-shaped tube 10. It should be noted that the first positioning line 3 is also arranged on the first protrusion 5.

[0039] In some embodiments, a second protrusion 6 is protruded on the positioning seat 1, and the second protrusion 6 is arranged in a right-angled trapezoidal block shape. The other end of the placement groove 2 is arranged on the second protrusion 6, so that the end of the special-shaped tube 10 located at the incision 102 is placed on the second protrusion 6, so that the end of the special-shaped tube 10 located at the incision 102 can be accurately and smoothly placed in the placement groove 2, and the special-shaped tube 10 partially protrudes out of the placement groove 2, which further facilitates the placement and removal of the special-shaped tube 10.

[0040] In some embodiments, a third protrusion 7 is protruded on the positioning seat 1, and the third protrusion 7 is arranged in a rectangular plate shape. The third protrusion 7 is located between the first protrusion 5 and the second protrusion 6. One side of the third protrusion 7 is integrally connected to one side of the first protrusion 5, and one end of the third protrusion 7 is integrally connected to one side of the second protrusion 6 to achieve the connection between the first protrusion 5 and the second protrusion 6, so as to improve the supporting strength of the first protrusion 5 and the second protrusion 6, thereby improving the overall structural strength of the positioning fixture.

[0041] In some embodiments, a positioning hole 8 is further provided on the first protruding portion 5, and the positioning hole 8 and the first positioning line 3 are spaced apart along the length direction of the placement groove 2 on the first protruding portion 5, and the position of the positioning hole 8 and the positioning mounting hole 101. In practical applications, when the end of the special-shaped tube 10 away from the incision 102 is aligned with the first positioning line 3, the mounting hole 101 of the special-shaped tube 10 needs to be aligned with the positioning hole 8, otherwise the processing accuracy of the special-shaped tube 10 does not meet the requirements, that is, the positioning fixture can detect the processing accuracy of the special-shaped tube 10 to improve the usability of the positioning fixture.

[0042] In some embodiments, a second positioning line 9 is provided on the second raised portion 6. The second positioning line 9 is inclined and is used to position the special-shaped tube 10 at one end of the incision 102. In actual applications, when the end of the special-shaped tube 10 away from the incision 102 is aligned with the first positioning line 3, the incision 102 of the special-shaped tube 10 needs to be aligned with the second positioning line 9, otherwise the processing accuracy of the special-shaped tube 10 does not meet the requirements, that is, the positioning fixture can detect the processing accuracy of the special-shaped tube 10 to improve the usability of the positioning fixture.

[0043] The implementation principle of this embodiment is as follows: in actual application, the staff first sets the rubber sleeve 11 on the special-shaped tube 10, and moves the rubber sleeve 11 to the middle position of the special-shaped tube 10 so that the rubber sleeve 11 is in an approximate bonding position, and then places the rubber sleeve 11 in the positioning groove 4. At this time, the position of the special-shaped tube 10 is moved according to the actual situation, so that the end of the special-shaped tube 10 away from the incision 102 is aligned with the first positioning line 3, and then a small amount of glue is dripped between the rubber sleeve 11 and the special-shaped tube 10 for pre-fixation, and finally the glue is taken out and dripped between the rubber sleeve 11 and the special-shaped tube 10 to achieve the rubber sleeve 11 being bonded and fixed to the special-shaped tube 10. In this process, the rubber sleeve 11 can be ensured to be in the correct bonding position as much as possible, thereby improving the fixing accuracy of the rubber sleeve 11, and the structure is simple and easy to operate.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
