[0035] The following further elaborates on the present utility model in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are merely for explaining the present utility model and not for limiting the present utility model. Additionally, it should be noted that for the sake of description, only the parts related to the present utility model rather than all the structures are shown in the drawings.
[0036] In the prior art, different types of shafts have different lengths. If the same fixture is used, some shafts cannot be placed on this fixture. Therefore, the operator needs to make fixtures of different sizes according to the length of the shaft. As a result, a large number of fixtures of different specifications need to be produced, and the volume of this kind of fixture is relatively large. Therefore, the operator needs a large amount of space to store these fixtures.
[0037] Therefore, as Figure 1 shown, in the embodiments of the present invention, a fixture for gear and shaft alignment is provided to solve the above technical problems.
[0038] Specifically, a fixture for gear and shaft alignment includes a first bracket 1 and a second bracket 2. The first bracket 1 and the second bracket 2 are respectively provided with a first fixing portion and a second fixing portion, and the first fixing portion and the second fixing portion are used to fix the shaft. The first bracket 1 and the second bracket 2 are connected by a telescopic device 3. The first bracket 1 and the second bracket 2 can move relative to each other under an external force to change the distance between the first bracket 1 and the second bracket 2. Therefore, the operator can adjust the distance between the first bracket 1 and the second bracket 2 in advance according to the actual length of the shaft, so that shafts of different lengths can be placed on the same fixture, thereby realizing that shafts of different lengths can share one fixture, reducing the number of fixtures produced, and saving the space for storing the fixtures.
[0039] In some embodiments, as Figure 1 shown, the telescopic device 3 includes a first sleeve 31 provided on the first bracket 1 and a second sleeve 32 provided on the second bracket 2. The first sleeve 31 is sleeved outside the second sleeve 32, or the second sleeve 32 is sleeved outside the first sleeve 31. When the first bracket 1 or the second bracket 2 is pushed forcefully, the second sleeve 32 and the first sleeve 31 will move relative to each other, and the length of the overlapping part between the second sleeve 32 and the first sleeve 31 will change, thereby changing the distance between the first bracket 1 and the second bracket 2 to meet the requirement that shafts of different lengths can be placed on the first bracket 1 and the second bracket. For the convenience of manufacturing and the longer service life of the fixture, the first sleeve 31 and the second sleeve 32 described here are preferably galvanized steel pipes or other metal pipes.
[0040] In some embodiments, to enhance the overall strength of the jig, the telescopic device 3 includes a first solid body disposed on the first bracket 1 and a second sleeve 32 disposed on the second bracket 2. The second sleeve 32 is sleeved outside the first solid body, and the shape of the second sleeve 32 matches that of the first solid body. When the first bracket 1 or the second bracket 2 is pushed forcefully, relative movement will occur between the first solid body and the second sleeve 32, and the length of the overlapping portion between the first solid body and the second sleeve 32 will change, thereby changing the distance between the first bracket 1 and the second bracket 2. Or the telescopic device 3 includes a first sleeve 31 disposed on the first bracket 1 and a second solid body disposed on the second bracket 2. The first sleeve 31 is sleeved outside the second solid body, and the shape of the first sleeve 31 matches that of the second solid body. When the first bracket 1 or the second bracket 2 is pushed forcefully, relative movement will occur between the first solid body and the second sleeve 32, and the length of the overlapping portion between the second solid body and the first sleeve 31 will change, thereby changing the distance between the first bracket 1 and the second bracket 2. For the convenience of manufacturing and the relatively long service life of the jig, the first solid body and the second solid body described herein are preferably metal solid round bars.
[0041] In some embodiments, at least two telescopic devices 3 are provided between the corresponding ends of the first bracket 1 and the second bracket 2, so as to improve the overall stability of the jig when the first bracket 1 or the second bracket 2 moves.
[0042] In some embodiments, when the first bracket 1 or the second bracket 2 moves to a distance desired by the operator between them, in order to prevent relative movement between the first sleeve 31 and the second sleeve 32, the first sleeve 31 and the second solid body, or the second sleeve 32 and the first solid body during the working process, the first sleeve 31 or the second sleeve 32 is provided with a locking structure 33.
[0043] In some embodiments, to save the manufacturing cost of the jig and the simplicity of operation, the locking structure 33 includes a bolt and a first threaded hole provided on the first sleeve 31 or a second threaded hole provided on the second sleeve 32. The bolt passes through the first threaded hole and abuts against the second sleeve 32 or the second solid body, or the bolt passes through the second threaded hole and abuts against the first sleeve 31 or the first solid body.
[0044] In some embodiments, a moving device 4 is provided on the end surface of the first bracket 1 and / or the second bracket 2 adjacent to the ground. The moving device 4 is used to move the first bracket 1 and the second bracket 2 to facilitate adjusting the distance between the first bracket 1 and the second bracket 2.
[0045] In some embodiments, the first bracket 1 includes two first components 11 which have a certain spacing therebetween and are both perpendicular to the horizontal plane; two second components 12 which are disposed between the two first components 11, with both ends of the two second components 12 being respectively connected to the first components 11, and the two second components 12 having a certain spacing and being both parallel to the horizontal plane; the second bracket 2 includes two third components 21 which have a certain spacing therebetween and are both perpendicular to the horizontal plane, and two fourth components 22 which are disposed between the two third components 21 and have a certain spacing therebetween, with both ends of the two fourth components 22 being respectively connected to the third components 21, and the two fourth components 22 being both parallel to the horizontal plane. The first components 11, second components 12, third components 21, and fourth components 22 form the main structure of the jig. Of course, the number of the first components 11, second components 12, third components 21, and fourth components 22 can also be increased according to actual needs. For the convenience of manufacturing and the relatively long service life of the jig, the first components 11 and third components 21 can be angle irons, and the second components 12 and fourth components 22 can be galvanized steel pipes or other metal pipes.
[0046] In some embodiments, the first fixing portion includes a first fixing member 13 and a second fixing member 14. One end of the first fixing member 13 and the second fixing member 14 are respectively connected to one end of the first component 11, and the other ends of the first fixing member 13 and the second fixing member 14 are respectively connected to the middle of the second component 12 away from the ground, and the first fixing member 13 and the second fixing member 14 are in abutment. The first fixing member 13 and the second fixing member 14 form a V shape, and the end of the first fixing member 13 and the second fixing member 14 connected to the first component 11 is higher than the end of the first fixing member 13 and the second fixing member 14 connected to the middle of the second component 12 away from the ground; the second fixing portion includes a third fixing member 23 and a fourth fixing member 24. One end of the third fixing member 23 and the fourth fixing member 24 are respectively connected to one end of the third component 21, and the other ends of the third fixing member 23 and the fourth fixing member 24 are respectively connected to the middle of the fourth component 22 away from the ground, and the third fixing member 23 and the fourth fixing member 24 are in abutment. The third fixing member 23 and the fourth fixing member 24 form a V shape, and the end of the third fixing member 23 and the fourth fixing member 24 connected to the third component 21 is higher than the end of the third fixing member 23 and the fourth fixing member 24 connected to the middle of the fourth component 22 away from the ground; the V shape formed by the first fixing member 13 and the second fixing member 14 corresponds to the V shape formed by the third fixing member 23 and the fourth fixing member 24. When shafts with different diameters are placed in the formed V-shaped structure, the V-shaped structure can hold the shafts, preventing the shafts from moving during the working process. For irregular shafts, such as crankshafts, the second component 12 away from the ground and the fourth component 22 away from the ground can also play a role in fixing them.
[0047] In some embodiments, to enhance the bearing capacity of the second component 12 and the fourth component 22, a first reinforcing column 15 extending downward to the ground or another second component 12 is provided in the middle of the second component 12 away from the ground and / or a second reinforcing column 25 extending downward to the ground or another fourth component 22 is provided in the middle of the fourth component 22 away from the ground.
