[0028] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0029] Example 1

[0030] See also Figure 1 and Figure 3This embodiment introduces a device for detecting the inclination of the end face of an aluminum alloy cast rod, which is mainly composed of a base 1, a roller assembly 2, a limit assembly 3 and a feeler gauge assembly 4.

[0031] The base 1 adopts a frame structure, and the top is in a rectangular frame shape, which is combined with the legs to form the base 1. The two short sides of the top of the base 1 are horizontally opened with openings 1 for installing the roller assembly 2, and the limit assembly 3 is installed in the middle section of the top of the short side, and the top of one of the long sides of the top of the base 1 is connected to the feeler gauge assembly 4.

[0032] like Figure 2 As shown, the roller assembly 2 is mainly composed of a roller 21, a movable block 23 and a telescopic cylinder 1 22. The roller 21 has an output shaft at the center of the circle, and the diameter of the output shaft is smaller than that of the roller 21. There are two rollers 21, which are parallel and horizontally located inside the top of the base 1, and the axial direction of the roller 21 is consistent with the length direction of the top of the base 1. The end of the output shaft of the roller 21 is located in the opening 1 of the base 1 and is connected to the movable block 23. The height of the movable block 23 is consistent with the height of the opening 1, so the top and bottom of the movable block 23 fit the inner wall of the opening 1, the length of the movable block 23 is greater than the width of the opening 1, and part of the movable block 23 is located outside the opening 1 and inside the top of the base 1. The fixed end of the telescopic cylinder 1 22 is installed on the top of the base 1, and the telescopic direction of the telescopic cylinder 1 22 is consistent with the width direction of the base 1. The movable end of the telescopic cylinder 1 22 is connected to the movable block 23, and one telescopic cylinder 1 22 corresponds to one movable block 23. The movable blocks 23 at both ends of the roller 21 can be driven to move in the opening 1 by the telescopic cylinder 1 22 , so as to adjust the distance between the two rollers 21 .

[0033] Since the aluminum alloy cast rod is placed in the gap between the tops of the two rollers 21, the spacing between the rollers 21 is adjusted according to the rod diameter of the aluminum alloy cast rod. If the rod diameter is large, the two rollers 21 move synchronously and horizontally in opposite directions to expand the spacing; if the rod diameter is small, the two rollers 21 move synchronously and horizontally toward each other to narrow the spacing, as long as the aluminum alloy cast rod does not fall off the top of the rollers 21.

[0034] Since the aluminum alloy cast rod needs to be rotated to adjust the angle when the end face cutting inclination is detected, the output shaft of the roller 21 is connected to the movable block 23 through a bearing, that is, the output shaft is axially embedded in the movable block 23, and the output shaft is located on the inner wall of the bearing, so that the roller 21 can rotate on its own and can rotate in coordination when the roller 21 is rotated.

[0035] The limiting assembly 3 is mainly composed of a support frame 31, a telescopic cylinder 2 32, a support plate 33, a telescopic cylinder 3 34 and a right-angle plate 35. The support frame 31 also adopts a frame structure, similar to a U-shape, and is installed on the top of the base 1. The top of the support frame 31 maintains a fixed distance from the top of the base 1. The fixed end of the telescopic cylinder 2 32 is longitudinally installed in the middle section of the top of the support frame 31, and the movable end faces downward and is connected to the support plate 33. The length of the support plate 33 is smaller than the length of the support frame 31. In order to stabilize the longitudinal stable linear movement of the support plate 33, limiting rods 38 are symmetrically arranged on both sides of the top of the support plate 33. A hole is opened on the top of the support frame 31 for the limiting rod 38 to pass through. The end of the limiting rod 38 is longitudinally supported by the support frame 31, and cooperates with the telescopic cylinder 2 32 to enable the support plate 33 to move longitudinally linearly stably.

[0036] There are two telescopic cylinders 34, which are symmetrically installed horizontally at the bottom of the support plate 33. The two telescopic cylinders 34 are distributed along the length direction of the support plate 33, that is, the length direction of the base 1, and the movement directions of the two telescopic cylinders 34 are opposite, and they are respectively connected to the right-angle plates 35. The telescopic cylinders 34 can drive the horizontal movement of the right-angle plates 35 and adjust the spacing between the symmetrical right-angle plates 35. It should be noted that all telescopic cylinders 1 22 extend or contract synchronously, so the center of the gap between the two rollers 21 is fixed, and the right-angle plate 35 is set above the midline of the gap between the two rollers 21, which can be kept on the end diameter line of the cast rod. However, the telescopic cylinders 34 do not need to extend or contract synchronously, and can be adjusted according to the length of the cast rod.

[0037] The right-angle plate 35 includes a first vertical portion, a horizontal portion, and a second vertical portion which are arranged in sequence; the first vertical portion and the horizontal portion are spliced ​​to form a right angle facing outward, and the horizontal portion and the second vertical portion are spliced ​​to form a right angle facing inward. The length of the first vertical portion is longer than the height of the telescopic cylinder 34 to ensure that the telescopic cylinder 34 does not contact the casting rod. The horizontal portion contacts the outer peripheral surface of the casting rod, and the second vertical portion forms a gap to be measured with the end surface of the casting rod.

[0038] In order to enable the second vertical portion to accommodate aluminum alloy cast rods with larger rod diameters, a second opening is provided at the bottom of the second vertical portion. The movable plate 36 is located in the second opening and fits against the inner wall of the second opening. A screw hole threadedly connected to the screw rod 37 is provided at the top of the second opening. The screw rod 37 is threadedly connected to the screw hole and the end of the screw rod 37 is connected to the movable plate 36 through a bearing. The bearing is embedded in the movable plate 36, and the end of the screw rod 37 is connected to the inner wall of the bearing.

[0039] If the horizontal portion is located at the top of the second vertical portion, a hole can be opened to allow the screw 37 to pass through without being blocked by the horizontal portion. Since the side wall of the movable plate 36 is in contact with the second inner wall of the opening, rotating the screw 37 can drive the movable plate 36 to move longitudinally. The movable plate 36 is blocked by the second vertical portion and can only move longitudinally without rotating. The downward movement of the movable plate 36 can extend the bottom of the second vertical portion, thereby adapting to aluminum alloy cast rods with larger rod diameters.

[0040] like Figure 4 As shown, the feeler gauge assembly 4 is mainly composed of a slide rail 41, a slide frame 42, a slider 43 and a measuring rod 44. The longitudinal cross-section of the slide rail 41 is similar to a "convex" shape. The slide rail 41 is arranged on the top of the base 1. The top of the slide frame 42 is provided with a hole adapted to the slide rail 41, which can maintain horizontal linear sliding on the slide rail 41. An opening 3 is opened downward from the top of the slide frame 42. The opening 3 only has a bottom wall and side walls symmetrical in the sliding direction of the slide rail 41, and the rest is unobstructed. The slider 43 is located in the opening 3 of the slide frame 42, and part of the structure of the slider 43 extends horizontally to the outside of the opening 3. In order to maintain the longitudinal linear movement of the slider 43 in the opening 3, a slide groove 1 is opened on the side wall of the opening 3, and the slider 43 is provided with an adapted sliding protrusion 1 facing the slide groove. The sliding protrusion 1 is located in the slide groove 1 to maintain the longitudinal movement of the slider 43 in the opening 3.

[0041] The middle of the slider 43 is provided with a hole through which the measuring rod 44 can pass. The measuring rod 44 includes an anti-slip section, a straight section and a feeler section which are arranged in sequence; the straight section crosses the hole of the slider 43, the anti-slip section is located outside the straight section, the thickness of the feeler section gradually decreases from one end connected to the straight section to the other end, the width of the end connected to the straight section is greater than the diameter of the straight section, and the feeler section has a scale for reference to the cutting slope of the aluminum alloy rod diameter.

[0042] In order to maintain the horizontal linear sliding of the straight tube section in the slider 43, the outer periphery of the straight tube section extends radially outward to form a sliding protrusion 2 (not shown in the figure), and the inner wall of the hole of the slider 43 is provided with a sliding groove 2 adapted to the sliding protrusion 2. The sliding protrusion 2 is located in the sliding groove 2 (not shown in the figure), which can prevent the straight tube section from rotating in the slider 43 and can only move linearly.

[0043] This embodiment can simultaneously measure the same relative position of two end faces of the same aluminum alloy cast rod through the cooperation of the limit assembly 3 and the feeler gauge assembly 4. The roller assembly 2 cooperates with the rotation of the aluminum alloy cast rod to switch different positions for measurement and obtain the maximum value of the end face cutting inclination; the limit assembly 3 can cooperate with the roller assembly 2 to automatically fit the end face of the aluminum alloy cast rod, reduce manual operation, and can be adjusted according to the rod diameter of the aluminum alloy cast rod, with strong versatility.

[0044] Example 2

[0045] This embodiment introduces a device for detecting the inclination of the end face of an aluminum alloy cast rod, which is basically the same in structure as the device for detecting the inclination of the end face of an aluminum alloy cast rod introduced in Example 1. The difference is that the measuring rod 44 of this embodiment only retains the feeler gauge section, and is connected to the top of the base 1 through a three-axis sliding module to achieve three-axis displacement adjustment of the measuring rod 44. The three-axis sliding module adopts an existing structure and is not described in detail here.

[0046] In this embodiment, the position adjustment of the feeler gauge can be adjusted by mechanical control, but the overall structure is more complicated. This embodiment has the same beneficial effects as the first embodiment.

[0047] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
