[0030] Example
[0031] Reference Figures 1-5 This utility model provides an adjustable-size winding mandrel, including a mandrel handle 100 and a base shaft 200. One end of the mandrel handle 100 is a connecting end 101, and the other end is a mounting end. An assembly hole 102 is provided at the mounting end of the mandrel handle 100, and a plurality of assembly grooves 103 are provided on the periphery of the mounting end, and the assembly grooves 103 communicate with the assembly hole 102.
[0032] The insertion end of the base shaft 200 is inserted into the assembly hole 102, and an annular fixing groove is provided at the insertion end. A first fixing hole 104 communicating with the assembly hole 102 is provided at the mounting end. A fixing member 400 is provided in the first fixing hole 104, and the fixing member 400 is inserted into the annular fixing groove.
[0033] The base shaft 200 is provided with a plurality of guide surfaces, each guide surface corresponding to an assembly groove 103; the guide surfaces include a front guide surface 201, a guide plane 202 and a rear guide surface 203, and the front guide surface 201 and the rear guide surface 203 gradually rise along a first direction; an adjustment block 300 is provided on the guide surface, and the adjustment block 300 is provided with a first guide surface 301 corresponding to the front guide surface 201, a second guide surface 302 corresponding to the guide plane 202 and a third guide surface 303 corresponding to the rear guide surface 203 in sequence facing the guide surface;
[0034] An adjustment elongated hole 304 is provided on the adjustment block 300, and an adjustment member 500 is passed through the adjustment elongated hole 304. The adjustment member 500 is screwed to the base shaft 200.
[0035] The first direction is the direction from the base shaft 200 to the mandrel shank 100.
[0036] In some embodiments, the connecting end 101 of the mandrel shank 100 of the adjustable-size winding mandrel has a mounting hole 102, and the insertion end of the base shaft 200 is inserted into the mounting hole 102, thereby realizing the connection between the base shaft 200 and the mandrel shank 100.
[0037] To prevent the base shaft 200 from detaching from the assembly hole 102, an annular fixing groove is provided on the base shaft 200, and multiple first fixing holes 104 are provided at the mounting end. A fixing member 400 is screwed into the first fixing hole 104. The fixing member 400 is generally a fixing bolt. The fixing member 400 is screwed into the first fixing hole 104, and the end of the fixing member 400 can be screwed into the annular fixing groove. In this way, the annular fixing groove cannot move relative to the fixing member 400, that is, the base shaft 200 cannot move relative to the mandrel shank 100, that is, the base shaft 200 cannot be separated from the mandrel shank 100.
[0038] The base shaft 200 is provided with multiple guide surfaces, with the front guide surface 201 and the rear guide surface 203 gradually rising. The adjusting block 300 is provided with a first guide surface 301 corresponding to the front guide surface 201 and a third guide surface 303 corresponding to the rear guide surface 203. When the adjusting block 300 moves in the first direction, the front guide surface 201 and the rear guide surface 203 cooperate to move the adjusting block 300 away from the base shaft 200 or closer to the base shaft 200, thereby adjusting the distance between the two opposing adjusting blocks 300 and realizing the adjustment of the specifications of the winding mandrel.
[0039] In order to fix the adjusting block 300 after adjustment, that is, to keep the size of the winding mandrel unchanged after adjustment, an adjusting elongated hole 304 is provided on the adjusting block 300. The adjusting member 500 passes through the adjusting elongated hole 304 and is screwed to the base shaft 200. This can effectively fix the adjusting block 300 and make it difficult for the adjusting block 300 to move.
[0040] Reference Figure 3 and Figure 5 In an optional embodiment, the adjusting elongated hole 304 is disposed on the third guide surface 303, and the rear guide surface 203 is provided with a second fixing hole 204, and the adjusting member 500 is screwed into the second fixing hole 204.
[0041] The adjusting elongated hole 304 can be provided on the first guide surface 301 or the third guide surface 303, or both the first guide surface 301 and the third guide surface 303 can be provided with the adjusting elongated hole 304; preferably, the adjusting elongated hole 304 is provided on the third guide surface 303, the adjusting elongated hole 304 penetrates the adjusting block 300, the adjusting member 500 is inserted into the adjusting elongated hole 304 on the side of the adjusting block 300 away from the base shaft 200 and into the second fixing hole 204 on the base shaft 200, and the second fixing hole 204 is a threaded hole.
[0042] In an optional embodiment, multiple guide surfaces are arranged in multiple pairs on the base shaft 200, and each pair of guide surfaces is provided with a guide hole 600 that connects the two guide surfaces.
[0043] A guide component is provided between the two adjusting blocks 300 corresponding to each pair of guide surfaces, and the guide component enables the two adjusting blocks 300 to move synchronously.
[0044] In an optional embodiment, the guide assembly includes a guide insert 700 and a guide slot 800, one of the adjustment blocks 300 is provided with the guide insert 700, the other of the adjustment blocks 300 is provided with the guide slot 800, and the guide insert 700 is inserted into the guide slot 800.
[0045] In some embodiments, multiple guide surfaces are arranged in multiple pairs, with each pair of two guide surfaces arranged in parallel. Each set of guide surfaces is provided with a guide plate 700 and a guide slot 800 on the corresponding adjustment block 300. The guide plate 700 is inserted into the guide slot 800, which enables the two adjustment blocks 300 to move synchronously. The guide plate 700 can extend and retract a distance within the guide slot 800 without disengaging from the guide slot 800. This ensures that the guide slot 800 and the guide plate 700 do not separate when adjusting the winding mandrel.
[0046] In an optional embodiment, the base shaft 200 is provided with four guide surfaces, and two adjacent guide surfaces are arranged in parallel.
[0047] In an optional embodiment, the base shaft 200 is provided with two guide holes 600, and the two guide holes 600 are spaced apart along the length direction of the base shaft 200.
[0048] In an optional embodiment, an even number of guide surfaces are uniformly arranged on the periphery of the base shaft 200.
[0049] In an optional embodiment, the first fixing hole 104 is disposed between the two mounting slots 103.
[0050] In some embodiments, the base shaft 200 has four guide surfaces and a guide hole 600 is provided on the base shaft 200. One guide hole 600 passes through a pair of guide surfaces, and two guide holes 600 are arranged sequentially along a first direction, so that the guide components will not interfere with each other.
[0051] The adjustable-size winding mandrel provided by this utility model can adjust the size of the winding mandrel by moving along the guide surface. Since both the front guide surface 201 and the rear guide surface 203 gradually rise along the first direction, the distance between the adjusting block 300 and the base shaft 200 gradually increases as the adjusting block 300 moves along the first direction, thereby realizing the adjustment of the winding mandrel and the size of the winding mandrel to adapt to the winding needs of different sized skeletons and improve production efficiency.
[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
