[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] First Embodiment

[0028] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 A schematic diagram of the first embodiment of a four-axis machining center fixture with an aluminum shell provided by this utility model; Figure 2 for Figure 1 The enlarged schematic diagram of part A shown below; Figure 3 for Figure 1 The diagram shows a side cross-sectional view of the positioning post. Figure 4 for Figure 3 The enlarged schematic diagram of section B is shown below; Figure 5 for Figure 4The diagram shows a top view of the threaded sleeve structure. A four-axis machining center fixture for aluminum shells includes: a four-axis rotary table 1, a fixed plate 11 fixedly mounted on the output end of the four-axis rotary table 1, a support base 12 fixedly mounted on the side of the fixed plate 11, a pneumatic telescopic rod 13 fixedly mounted on the top of the support base 12, and a limit rod 14 fixedly mounted on the moving end of the pneumatic telescopic rod 13.

[0029] A positioning post 3 is disposed on the front side of the fixed plate 11. A sliding groove 31 is formed around the positioning post 3. A rotating handle 32 is rotatably connected to one end of the positioning post 3. A bidirectional threaded rod 33 is fixedly installed at one end of the rotating handle 32. Threaded sleeves 34 are threadedly connected to both ends of the outer side of the bidirectional threaded rod 33. A first rotating seat 35 is fixedly installed around the two threaded sleeves 34. A connecting rod 36 is rotatably connected inside the first rotating seat 35. A second rotating seat 37 is rotatably connected to one end of the connecting rod 36. An abutment plate 38 is fixedly installed on the side of the second rotating seat 37. The abutment plate 38 is disposed on the inner side of the sliding groove 31.

[0030] The positioning post 3 has four sliding grooves 31 on its side, and the inner side of each of the four sliding grooves 31 has a sliding abutment plate 38. Two second rotating seats 37 are installed on one side of each abutment plate 38, and the two rotating seats 37 are arranged opposite each other.

[0031] One end of the bidirectional threaded rod 33 is rotatably connected to the other end of the inner side of the positioning post 3.

[0032] By rotatably connecting one end of the bidirectional threaded rod 33 to the other end of the inner side of the positioning post 3, the stability of the bidirectional threaded rod 33 during rotation can be increased.

[0033] The side of the abutment plate 38 is attached to both sides of the inner side of the slide groove 31, and one end of the abutment plate 38 is inclined.

[0034] The abutment plate 38 slides on the inner side of the groove 31, which can limit the position of the abutment plate 38 during use. One end of the abutment plate 38 is set in an inclined shape so that the user can put the workpiece on the outer side of the abutment plate 38.

[0035] A fixing ring 2 is fixedly installed on the front of the fixing plate 11, and locking screws 21 are threadedly connected to the inside of both sides of the fixing ring 2.

[0036] The other end of the positioning post 3 is located on the inner side of the fixing ring 2, and one end of the locking screw 21 abuts against the side of the positioning post 3.

[0037] The fixing ring 2 and the locking screw 21 make it easy for the user to disassemble the positioning post 3 during use.

[0038] The working principle of the aluminum shell four-axis machining center fixture provided by this utility model is as follows:

[0039] When limiting the inner diameter of a workpiece, the user can first place a workpiece on the outer side of the positioning post 3, and then rotate the handle 32 to drive the bidirectional threaded rod 33 to rotate. Then, the two threaded sleeves 34 are threadedly connected on the outer side of the bidirectional threaded rod 33 and move to both ends, thereby pushing the connecting rod 36 through the first rotating seat 35. One end of the first rotating seat 35 is rotatably connected inside the second rotating seat 37. Then, the abutment plate 38 is pushed from the inner side of the slide groove 31 to the outer side, so that the side of the abutment plate 38 abuts against the inner side of the workpiece, so as to accommodate workpieces of different diameters. In this way, when processing workpieces of the same diameter in the future, it is only necessary to place the workpiece on the outer side of the abutment plate 38, and then extend the telescopic rod 13 to drive one end of the limiting rod 14 to abut against the side of the workpiece, thereby limiting the workpiece.

[0040] Compared with related technologies, the aluminum shell four-axis machining center fixture provided by this utility model has the following beneficial effects:

[0041] The positioning pin 3, slide groove 31, rotating handle 32, bidirectional threaded rod 33, threaded sleeve 34, first rotating seat 35, connecting rod 36, second rotating seat 37, and abutment plate 38 work together. In use, rotating the rotating handle 32 drives the bidirectional threaded rod 33 to connect the two threaded sleeves 34. Then, the first rotating seat 35, connecting rod 36, and second rotating seat 37 push the abutment plate 38 out from the inner side of the slide groove 31 and abut against the inner side of the workpiece. In this way, the position of the abutment plate 38 can be adjusted according to the inner diameter of the workpiece to adapt to workpieces with different inner diameters, thereby increasing the adaptability of the device.

[0042] Second Embodiment

[0043] Please refer to Figure 6 and Figure 7 Based on the aluminum shell four-axis machining center fixture provided in the first embodiment of this application, the second embodiment of this application proposes another aluminum shell four-axis machining center fixture. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0044] Specifically, the second embodiment of this application provides a different aluminum shell four-axis machining center fixture in that the abutment plate 38 has a snap-fit ​​groove 4 on its side, and a snap-fit ​​strip 41 is snapped into the inner side of the snap-fit ​​groove 4.

[0045] A rubber strip 42 is fixedly installed on one side of the snap-fit ​​strip 41.

[0046] The snap-fit ​​groove 4 and snap-fit ​​strip 41 make it convenient for users to disassemble and replace the rubber strip 42 during use.

[0047] The working principle of the aluminum shell four-axis machining center fixture provided by this utility model is as follows:

[0048] When in use, the user inserts the snap-fit ​​strip 41 into the inner side of the snap-fit ​​groove 4 to install the rubber strip 42. When the workpiece is placed on the outer side of the abutment plate 38 during subsequent use, the side of the rubber strip 42 and the inner side of the workpiece can abut against each other, thereby protecting the workpiece.

[0049] Compared with related technologies, the aluminum shell four-axis machining center fixture provided by this utility model has the following beneficial effects:

[0050] The snap-fit ​​groove 4, snap-fit ​​strip 41, and rubber strip 42 work together to form a structure that allows the snap-fit ​​strip 41 to be snapped into the inner side of the snap-fit ​​groove 4 during use, thereby installing the rubber strip 42. When processing the workpiece, the rubber strip 42 comes into contact with the inner side of the workpiece, thus protecting the workpiece.

[0051] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
