[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a milling machine fixture based on a fixture thin area support structure, including a milling machine body 1, a mounting seat 2 is provided above the processing platform of the milling machine body 1, the milling machine body 1 and the mounting seat 2 are detachably connected, and the connection method between the milling machine body 1 and the mounting seat 2 is a well-known technology in this field, which can be implemented by technical personnel in this field, so it will not be described in detail in this case. A movable groove 3 is provided at the top of the mounting seat 2.

[0035] Reference Figure 2 and Figure 3 The inner wall of the movable groove 3 is rotatably connected with a bidirectional threaded rod 4, and the left and right outer walls of the bidirectional threaded rod 4 are provided with threaded grooves with equal pitch and opposite directions. The right end of the bidirectional threaded rod 4 passes through the inner wall of the mounting seat 2, and the setting of the thread grooves with the same pitch and opposite directions ensures that the objects at the thread grooves on both sides of the bidirectional threaded rod 4 can move in opposite directions with the rotation of the bidirectional threaded rod 4. The inner wall of the movable groove 3 is slidably connected with a slider 5, and the inner wall of the slider 5 passes through and is threadedly connected to the outer wall of the bidirectional threaded rod 4. The number of sliders 5 is set to two, and the two sliders 5 are respectively arranged in the areas where the threads in different directions of the bidirectional threaded rod 4 are located. The top of the slider 5 is fixedly connected with a mounting block 6, and the number of the mounting blocks 6 is set to two, and the bottom ends of the two mounting blocks 6 are respectively fixedly connected to the tops of two different sliders 5.

[0036] Reference Figure 2and Figure 3 , a fixing mechanism 7 is provided inside the mounting block 6, and the fixing mechanism 7 includes a mounting groove 71. The mounting groove 71 is opened at one end of the two mounting blocks 6 close to each other. The inner wall of the mounting groove 71 passes through and is rotatably connected to a screw rod 72. The top of the screw rod 72 is outside the mounting block 6, and the outer wall of the screw rod 72 passes through and is threadedly connected to a moving block 73. The outer wall of the moving block 73 is slidably connected to the inner wall of the mounting groove 71. The sliding direction of the moving block 73 is up and down. The end of the moving block 73 close to the middle of the mounting seat 2 is fixedly connected to a fixing plate 74. The outer wall of the moving block 73 at the lower end of the fixing plate 74 is fixedly connected to a lower clamping plate 75. The moving block 73 is on the fixing plate 74 The upper splint 76 is slidably connected to the outer wall between the lower splint 75. The size and length of the upper splint 76 and the lower splint 75 are equal. The upper splint 76 and the lower splint 75 are both composed of a metal inner core and an outer rubber outer shell. The material setting of the upper splint 76 and the lower splint 75 ensures that the upper splint 76 and the lower splint 75 have the ability to clamp and support the thin film area, and at the same time, it is not easy for the thin film area to deform due to its relatively hardness. The top end of the upper splint 76 is elastically connected to the bottom end of the fixed plate 74 by a spring 77. One end of the spring 77 is fixedly connected to the top end of the upper splint 76, and the other end of the spring 77 is fixedly connected to the bottom end of the fixed plate 74.

[0037] Reference Figure 4 - Figure 6 The top of the upper clamping plate 76 and the bottom of the lower clamping plate 75 are both provided with a clamping assembly 8, and the clamping assembly 8 includes a mounting shell 81. Each set of fixing mechanisms 7 includes two sets of clamping assemblies 8. Through the arrangement of the two sets of clamping assemblies 8, it is ensured that the outer wall of the workpiece in the area above the upper clamping plate 76 and the area below the lower clamping plate 75 can obtain a better fixing effect under the clamping action of the clamping assembly 8. The bottom end of the mounting shell 81 of one set of clamping assemblies 8 is fixedly connected to the top of the upper clamping plate 76, and the top of the mounting shell 81 of the other set of clamping assemblies 8 is fixedly connected to the bottom of the lower clamping plate 75. The mounting shell A positioning rod 82 passes through and is slidably connected to the inner wall of 81. The number of positioning rods 82 is set to be several, and the several positioning rods 82 are not connected to each other. By setting multiple positioning rods 82, it is ensured that by setting multiple positioning rods 82 in different positions, the effect of fixing objects of different shapes can be achieved. The end of the positioning rod 82 away from the middle of the mounting seat 2 is elastically connected to the inner wall of the mounting shell 81 through spring 2 83, one end of spring 2 83 is fixedly connected to the end of the positioning rod 82 away from the middle of the mounting seat 2, and the other end of spring 2 83 is fixedly connected to the inner wall of the mounting shell 81.

[0038] Reference Figure 5 - Figure 7The inner wall of the mounting shell 81 is provided with a sliding groove 84, and the inner wall of the sliding groove 84 is slidably connected with a moving rod 85. The moving rod 85 is composed of a plurality of long rods with longer front and rear ends and shorter upper and lower ends, and a vertical rod with longer upper and lower ends and shorter front and rear ends. The top of the moving rod 85 is fixedly connected with a positioning block 86, and the bottom end of the positioning rod 82 is provided with a positioning hole 87. The shape and size of the positioning block 86 can be matched with the shape of the positioning hole 87, and the top shape of the positioning block 86 is hemispherical. The positioning block 86 is positioned to ensure that it can just enter the positioning hole 87 to achieve the positioning effect of the positioning rod 82. The hemispherical shape is set to ensure that the positioning block 86 can more easily enter the positioning hole 87. A slide groove 88 is provided at the front end of the mounting shell 81. The front end of the movable rod 85 is fixedly connected to the control block 89. The top and bottom ends of the slide groove 88 are both provided with magnets. The material of the control block 89 is set to iron. Through the material setting, it is ensured that when the control block 89 moves to the top and bottom ends of the slide groove 88, it will not move in the absence of external force.

[0039] Working principle: When in use, the staff first rotates the screw rod 72 so that the moving block 73 can move up and down driven by the screw rod 72. When the staff adjusts the moving block 73 so that the top of the lower clamping plate 75 and the bottom end of the edge slice of the workpiece are at the same horizontal position, the staff moves the upper clamping plate 76 upward and places the edge slice of the workpiece into the upper area of ​​the lower clamping plate 75. When the placement is completed, the staff releases the upper clamping plate 76. At this time, the upper clamping plate 76 moves downward driven by the spring 77, thereby achieving the effect of fixing the edge slice of the workpiece.

[0040] When the edge slice on one side of the workpiece is fixed, the staff adjusts the position of the moving block 73 on the other side, and then rotates the bidirectional threaded rod 4. When the workpiece contacts the fixing mechanism 7 on the other side, the staff places the slice of the workpiece between the upper clamping plate 76 and the lower clamping plate 75 on the other side, and then continues to rotate the bidirectional threaded rod 4, so that the two sets of fixing mechanisms 7 continue to move toward each other.

[0041] During the process of continuing to move, since the moving rod 85 moves with the movement of the upper clamping plate 76 and the lower clamping plate 75, when the moving rod 85 is obstructed by the surface of the workpiece, the obstructed moving rod 85 cannot continue to move, while the other moving rods 85 continue to move normally. Therefore, when the thin film area is completely clamped, the surface of the moving rod 85 is pushed by the outer wall of the workpiece to complete the shape determination.

[0042] When the position of the moving rod 85 is determined, the staff pushes the control block 89 upward, so that the control block 89 drives the moving rod 85 to move upward, thereby causing the moving rod 85 to drive the positioning block 86 to move upward, thereby causing the positioning block 86 to enter the positioning hole 87. When the positioning block 86 enters the positioning hole 87, the moving rod 85 cannot continue to move. Therefore, at this time, the moving rod 85 can achieve a better fixing effect on the workpiece in the upper and lower end areas of the sheet.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
