DETAILED DESCRIPTION

[0025] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] See also Figure 1 to Figure 7As shown, an insulating material milling fixture device includes a workbench 1, a movable table 6 and a milling machine 7. The workbench 1 includes a pressing plate 2, a turntable 3, a rotary table 4 and a telescopic rod 5. The workbench 1 is placed on the milling machine 7. The movable table 6 is arranged on one side of the milling machine 7 and is connected to the workbench 1 to achieve lateral and longitudinal displacement adjustment of the insulating material. The pressing plate 2 is installed on the upper surface of the turntable 3 to fix the insulating material. The turntable 3 is arranged at the center of the turntable 4 and is rotatably connected to the turntable 4. The turntable 4 is arranged directly above the workbench 1. One end of the four telescopic rods 5 is connected to the bottom of the turntable 4, and the other end is connected to the top of the workbench 1. The four telescopic rods 5 are independently extended and contracted to tilt the turntable 4 to change the angle formed by the insulating material on the turntable 3 and the horizontal plane.

[0027] The device realizes the lifting and tilting of the insulating material through the workbench 1 so as to accurately detect the insulating material. The turntable 3 rotates on the turntable 4 to drive the insulating material to vertically contact the tool of the milling machine 7 at different positions. For the parts of the insulating material sample with large thickness errors, the telescopic rod 5 is raised and lowered around the turntable 4 to adjust the entry angle of the milling tool, so that the tool is milled into the sample from the part with lower thickness, increasing the grinding method while avoiding mechanical damage to the tool.

[0028] See also Figure 1 to Figure 3 As shown, the pressing plate 2 includes a fixing groove 21, a positioning pile 22 and a pressing plate 2 hole. The fixing groove 21 is opened on the side of the pressing plate 2 close to the bottom, the positioning pile 22 is installed on the upper surface of the pressing plate 2, and the pressing plate 2 hole is set at the center of the positioning pile 22 and passes through the fixing groove 21.

[0029] The fixing groove 21 is used to press the two ends of the insulating material, and the positioning pile 22 is used to drill bolt holes. The bolts are passed through the holes of the pressure plate 2 to firmly nail the insulating material to the upper surface of the turntable 3 to prevent the reaction force of the rotation of the milling machine 7 tool when it contacts the insulating material from causing the offset of the insulating material and resulting in a reduction in detection accuracy.

[0030] See also Figure 3 As shown, the turntable 3 includes a circular groove 31, a fixing hole 32, a first bevel gear 33 and a second bevel gear 34. The circular groove 31 is arranged at the center of the turntable 4, and the fixing holes 32 are arranged in an array on the upper surface of the turntable 3. The first bevel gear 33 is fixedly installed at the bottom of the turntable 3 and is rotatably connected to the turntable 4. The second bevel gear 34 is rotatably installed on the turntable 4 and is vertically meshed with the first bevel gear 33.

[0031] The circular groove 31 is used to install the entire turntable 3. The fixing hole 32 corresponds to the size of the hole of the pressing plate 2 on the pressing plate 2, ensuring that the pressing plate 2 can be fixed on the upper surface of the turntable 3. The first bevel gear 33 is driven by the second bevel gear 34 to rotate, thereby driving the rotation of the turntable 3. The rotation of the gear can accurately control the rotation angle, further improving the detection accuracy of the insulating material.

[0032] See also Figure 1 to Figure 5 As shown, the turntable 4 includes a knob 41, a connecting rod 42, a steering gear 43 and a first connecting platform 44. The knob 41 is rotatably mounted on the upper surface of the turntable 4, the steering gear 43 is arranged directly below the knob 41, the connecting rod 42 is installed on the steering gear 43, and the first connecting platform 44 is arranged at the bottom of the turntable 4 and is rotatably connected to the telescopic rod 5.

[0033] The knob 41 is used to control the rotation of the turntable 3, and the connecting rod 42 is used to connect the steering gear 43 and the second bevel gear 34 on the turntable 3, so that a mechanical connection is formed between the knob 41 and the turntable 3. Since the turntable 4 will tilt and rotate on the workbench 1, it is inconvenient to set the knob 41 on the side of the turntable 4. The installation direction of the knob 41 is changed by the steering gear 43 so that it is axially parallel to the turntable 3 for easy control. The first connecting platform 44 is used to position and install the telescopic rod 5.

[0034] See also Figure 1 to Figure 6 As shown, the telescopic rod 5 includes a rotating joint 51, a second connecting platform 52, a rotating cylinder 53 and a spring 54. The rotating joints 51 are arranged at both ends of the telescopic rod 5, the second connecting platform 52 is arranged on the upper surface of the workbench 1, the rotating cylinder 53 is rotatably connected to the second connecting platform 52 and is simultaneously rotatably connected to the rotating joint 51, and the spring 54 is surrounded by the outside of the telescopic rod 5 and is arranged between the two rotating joints 51.

[0035] A rotating connection is formed between the rotating joint 51 and the first connecting platform 44 and the second connecting platform 52 to relieve the spatial constraints generated when the turntable 4 is raised and lowered. The rotating cylinder 53 is used to relieve the planar constraints generated by the second connecting platform 52 on the turntable 4, ensuring that the four telescopic rods 5 will not get stuck with each other, causing the turntable 4 to be unable to rise and fall. The spring 54 is used to provide elastic margin when the milling machine 7 contacts the insulating material to avoid excessive instantaneous pressure from damaging the telescopic rods 5.

[0036] See also Figure 1 to Figure 7 As shown, the movable platform 6 includes a sleeve frame 61, a slide groove 62 and a cover plate 63. The sleeve frame 61 is placed on the upper surface of the movable platform 6 and connected to the workbench 1. The cover plate 63 covers the sleeve frame 61. The slide groove 62 is arranged in an array on the upper surface of the movable platform 6.

[0037] The sleeve frame 61 controls the workbench 1 to move longitudinally perpendicular to the movable table 6, the cover plate 63 is used to control the lateral movement of the workbench 1, and the slide groove 62 is used to clamp the cover plate 63. After the cover plate 63 is fixed, the sleeve frame 61 is clamped to ensure that the insulating material on the workbench 1 will not cause deviation when it contacts the milling machine 7, thereby forming a detection error.

[0038] See also Figure 7As shown, the sleeve frame 61 includes a threaded rod 611 and an engaging groove 612 . The threaded rod 611 passes through the sleeve frame 61 and is connected to the workbench 1 . The engaging groove 612 is arranged at the bottom of the cover plate 63 and is slidably connected to the sleeve frame 61 .

[0039] The threaded rod 611 is used to control the extension and retraction of the workbench 1. By rotating the threaded rod 611, relative displacement can occur between the workbench 1 and the sleeve 61. At the same time, the threaded engagement can also accurately control the displacement distance. The engaging groove 612 is used to install the sleeve 61 while allowing the cover plate 63 to control the lateral movement of the sleeve 61.

[0040] See also Figure 7 As shown, the cover plate 63 includes a positioning hole 631 and a screw 632. The positioning hole 631 is arranged on both sides of the cover plate 63, and the screw 632 is installed in the positioning hole 631. The positioning hole 631 is used to install the screw 632. At the same time, the size of the positioning hole 631 corresponds to the groove width of the slide groove 62, ensuring that the activity of the cover plate 63 can be controlled by nailing the screw 632.

[0041] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
