Description

Technical Field

[0001] This application belongs to the technical field of alignment mechanisms, and particularly relates to an angle adjustment method for an alignment mechanism. Background Art

[0002] In mechanical mechanisms, it is often necessary for working components to align with a fixed working point along a straight line, but the alignment angle needs to be adjusted. Such working components are usually clamped by a set of alignment mechanisms, and the alignment mechanisms are installed on a fixed fixing frame.

[0003] When the fixed working point is far from the fixing frame, the alignment mechanism needs to move a large distance, and the alignment mechanism occupies a large volume. Therefore, such alignment mechanisms are often limited by the overall size of the machine, resulting in a small angle adjustment range for such alignment mechanisms. Some alignment mechanisms also have the problem of not being able to continuously adjust the angle. When some alignment mechanisms operate, the alignment mechanism and the fixing frame are in a separated state. When the alignment mechanism is adjusted in place, it needs to be fixed to the fixing frame again. Therefore, it is inconvenient to operate for large machinery. Summary of the Invention

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0041] As Figures 1 to 5 shown, the angle adjustment method of the alignment mechanism provided by the embodiments of the present invention uses an alignment mechanism with adjustable angles. The mechanism includes a working component 8, a C-shaped hanger 5, a fixed frame 1, a first connecting rod 2, a first adjusting rod 31, a first adjusting sleeve 32, and a second connecting rod 4. The fixed frame 1 is fixedly installed, and the fixed frame 1 is located on one side of the opening of the C-shaped hanger 5. The working component 8 is installed below the C-shaped hanger 5. The fixed end of the first connecting rod 2 and the fixed frame 1 are hinged at the first fixed point 11. The movable end of the first connecting rod 2 and the C-shaped hanger 5 are hinged at the first hinge point 51. The end of the first adjusting rod 31 and the fixed frame 1 are hinged at the second fixed point 12. The first adjusting sleeve 32 is telescopically sleeved on the first adjusting rod 31, and the middle part of the first adjusting sleeve 32 and the first connecting rod 2 are hinged at the sixth hinge point 23. The sixth hinge point 23 is located above the second fixed point 12. The fixed end of the second connecting rod 4 and the fixed frame 1 are hinged at the third fixed point 13. The movable end of the second connecting rod 4 and the C-shaped hanger 5 are hinged at the second hinge point 52. The second hinge point 52 is located below the first hinge point 51.

[0042] The first adjusting sleeve 32, the first adjusting rod 31, the first connecting rod 2, and the second connecting rod 4 are all located on one side of the opening of the C-shaped hanger 5. The fixed frame 1 is the fixed foundation of the mechanism, and all parts are directly or indirectly installed on the fixed frame 1 through a link mechanism. The first adjusting assembly 3 includes the first adjusting rod 31 and the first adjusting sleeve 32.

[0043] As Figure 5As shown, in this embodiment, one end of the first adjusting rod 31 is sleeved with a first adjusting sleeve 32, and the other end of the first adjusting rod 31 is hinged to a support 33, and the support 33 is fixed on the fixing frame 1. A spherical plain bearing is provided between the end of the first adjusting rod 31 and the support 33. One end of the adjusting inner rod 34 passes through the first adjusting sleeve 32 and is threadedly connected to the inside of the first adjusting rod 31. The other end of the adjusting inner rod 34 is provided with an annular boss 35 and a positioning block 36. The positioning block 36 and the adjusting inner rod 34 are rotatably connected. The annular boss 35 is located between the positioning block 36 and the first adjusting sleeve 32, and the first adjusting sleeve 32 is connected to the positioning block 36.

[0044] It should be noted that when the adjusting inner rod 34 is rotated, since the adjusting inner rod 34 is threadedly connected to the first adjusting rod 31, and the end of the first adjusting rod 31 is hinged to the second fixed point 12, the adjusting inner rod 34 and the first adjusting rod 31 move relative to each other. The first adjusting sleeve 32 is connected to the positioning block 36, so that the first adjusting rod 31 and the first adjusting sleeve 32 move relative to each other, thereby realizing the movement mode of the first adjusting sleeve 32 moving on the first adjusting rod 31, and thus realizing the telescopic function.

[0045] In this embodiment, the third fixed point 13 is located diagonally below the second fixed point 12 and close to the side of the C-shaped hanger 5.

[0046] In this embodiment, the C-shaped hanger 5 includes an upper rod member 56, a middle rod member 57, and a lower rod member 58 connected in sequence. The upper rod member 56, the middle rod member 57, and the lower rod member 58 form a C-shaped structure. The first hinge point 51 is located at the end of the upper rod member 56. The second hinge point 52 is located at the upper part of the middle rod member 57.

[0047] In this embodiment, it further includes a second adjusting rod 62, a second adjusting sleeve 61, a third L-shaped connecting rod 7, and a fourth connecting rod 9. The second adjusting rod 62 is telescopically sleeved in the second adjusting sleeve 61. The middle part of the second adjusting sleeve 61 is hinged to the C-shaped hanger 5 at the third hinge point 53. The third L-shaped connecting rod 7 is in an L-shaped structure. The inflection point of the third L-shaped connecting rod 7 is hinged to the C-shaped hanger 5 at the fourth hinge point 54. The third L-shaped connecting rod 7 and the second adjusting sleeve 61 are located on the side of the C-shaped hanger 5 away from the fixing frame 1. The end of the second adjusting rod 62 and the upper end of the third L-shaped connecting rod 7 are hinged at the seventh hinge point 71. The seventh hinge point 71 is located below the third hinge point 53. The upper end of the fourth connecting rod 9 is hinged to the C-shaped hanger 5 at the fifth hinge point 55. The fifth hinge point 55 is located at the end of the lower rod member 58. The alignment end 82 of the working part 8 and the lower end of the fourth connecting rod 9 are hinged at the ninth hinge point 81. The adjustment end 83 of the working part 8 and the lower end of the third L-shaped connecting rod 7 are hinged at the eighth hinge point 72, and the eighth hinge point 72 and the fixed working point 10 are respectively located on both sides of the ninth hinge point 81.

[0048] In this embodiment, the third hinge point 53 is located at the connection of the upper rod member 56 and the middle rod member 57.

[0049] In this embodiment, the third L-shaped connecting rod 7 includes an upper inclined rod member 73 and a lower inclined rod member 74 which are connected to each other, and the upper inclined rod member 73 and the lower inclined rod member 74 form a set angle. The fourth hinge point 54 is located at the connection of the upper inclined rod member 73 and the lower inclined rod member 74. The end of the second adjusting rod 62 and the end of the upper inclined rod member 73 are hinged at the seventh hinge point 71. The adjusting end 83 of the working member 8 and the end of the lower inclined rod member 74 are hinged at the eighth hinge point 72.

[0050] As Figures 1 to 5 shown, the angle adjustment method of the alignment mechanism provided by the embodiment of the present invention includes the steps of controlling the C-shaped hanger 5 to move relative to the fixed frame 1 to adjust the angle of the working member 8, and controlling the working member 8 to move relative to the C-shaped hanger 5 to adjust the angle of the working member 8.

[0051] The step of controlling the C-shaped hanger 5 to move relative to the fixed frame 1 to increase the angle of the working member 8, and the step of controlling the working member 8 to move relative to the C-shaped hanger 5 to increase the angle of the working member 8, or the step of controlling the C-shaped hanger 5 to move relative to the fixed frame 1 to decrease the angle of the working member 8, and the step of controlling the working member 8 to move relative to the C-shaped hanger 5 to decrease the angle of the working member 8. These steps can be implemented simultaneously or successively.

[0052] The step of controlling the C-shaped hanger 5 to move relative to the fixed frame 1 to increase the angle of the working member 8 includes:

[0053] Controlling the first adjusting assembly 3 to extend, so that the first adjusting sleeve 32 moves upward on the first adjusting rod 31.

[0054] The first adjusting sleeve 32 drives the first connecting rod 2 to rotate around the fixed end of the first connecting rod 2, that is, the first fixed point 11, so that the movable end of the first connecting rod 2, that is, the first hinge point 51, moves upward in an arc. The arc movement mentioned in this embodiment means that the movement track is an arc.

[0055] The movable end of the first connecting rod 2, that is, the first hinge point 51, drives the upper end of the C-shaped hanger 5 to move upward in an arc, and at the same time, the middle part of the C-shaped hanger 5 moves upward in an arc with the fixed end of the second connecting rod 4, that is, the third fixed point 13 as the center under the constraint of the second connecting rod 4. The first adjusting assembly 3, the first connecting rod 2 and the second connecting rod 4 are all located on one side of the opening of the C-shaped hanger 5. The fixed end of the first connecting rod 2 and the fixed end of the second connecting rod 4 are hinged to the fixed frame 1, and the movable end of the second connecting rod 4 is hinged to the middle part of the C-shaped hanger 5.

[0056] The C-shaped hanger 5 moves upward in an arc relative to the fixed frame 1 under the combined action of the first connecting rod 2 and the second connecting rod 4.

[0057] The C-shaped hanger 5 drives the adjustment end 83 of the working component 8 below it to make an arc movement upward with the fixed working point 10, thereby realizing the movement mode in which the working component 8 always aligns with the fixed working point 10 when the angle increases.

[0058] In this embodiment, the steps of controlling the C-shaped hanger 5 to move relative to the fixed frame 1 to reduce the angle of the working component 8 include:

[0059] Control the first adjustment component 3 to shorten, so that the first adjustment sleeve 32 moves downward on the first adjustment rod 31.

[0060] The first adjustment sleeve 32 drives the first connecting rod 2 to rotate with the fixed end of the first connecting rod 2, so that the movable end of the first connecting rod 2 makes an arc movement downward.

[0061] The movable end of the first connecting rod 2 drives the upper end of the C-shaped hanger 5 to make an arc movement downward, and at the same time, the middle part of the C-shaped hanger 5 makes an arc movement downward with the fixed end of the second connecting rod 4 as the center under the constraint of the second connecting rod 4.

[0062] The C-shaped hanger 5 makes an arc movement downward under the combined action of the first connecting rod 2 and the second connecting rod 4.

[0063] The C-shaped hanger 5 drives the adjustment end 83 of the working component 8 below it to make an arc movement downward with the fixed working point 10, thereby realizing the movement mode in which the working component 8 always aligns with the fixed working point 10 when the angle decreases.

[0064] It should be noted that when the C-shaped hanger 5 makes an arc movement downward, the C-shaped hanger 5 not only changes in the up-and-down position and the left-and-right position, but also changes in the angle relative to the fixed frame 1. Through this mechanism, the alignment angle of the working component 8 of the device to a fixed working point 10 outside the device can be adjusted.

[0065] In this embodiment, the steps of controlling the working component 8 to move relative to the C-shaped hanger 5 to increase the angle of the working component 8 include:

[0066] Control the second adjustment component 6 to extend, so that the second adjustment rod 62 moves downward in the second adjustment sleeve 61.

[0067] The second adjustment rod 62 drives the upper end of the third L-shaped connecting rod 7, that is, the seventh hinge point 71, to rotate with the inflection point of the third L-shaped connecting rod 7, that is, the fourth hinge point 54, as the center, so that the upper end of the third L-shaped connecting rod 7 makes an arc movement downward, and the lower end of the third L-shaped connecting rod 7, that is, the eighth hinge point 72, makes an arc movement upward. The third L-shaped connecting rod 7 and the second adjustment component 6 are located on the side of the C-shaped hanger 5 away from the first connecting rod 2.

[0068] The lower end of the third L-shaped connecting rod 7 drives the adjustment end 83 of the working component 8 to make an arc movement upward.

[0069] The alignment end 82 of the working component 8 moves in an arc with the fixed end of the fourth link 9, i.e., the fifth hinge point 55, as the center under the constraint of the fourth link 9. The fixed end of the fourth link 9 and the inflection point of the third L-shaped link 7 are hinged to the C-shaped hanger 5, and the movable end of the fourth link 9, i.e., the ninth hinge point 81, is hinged to the alignment end 82 of the working component 8.

[0070] The adjustment end 83 of the working component 8 moves in an arc upward under the combined action of the fourth link 9 and the third L-shaped link 7, and the alignment end 82 of the working component 8 moves in an arc under the combined action of the fourth link 9 and the third L-shaped link 7. The moving distance of the adjustment end 83 of the working component 8 is greater than the moving distance of the alignment end 82 of the working component 8, so that the working component 8 always aligns with the fixed working point 10 when the angle of the working component 8 increases.

[0071] In this embodiment, the steps of controlling the relative movement of the working component 8 with respect to the C-shaped hanger 5 to reduce the angle of the working component 8 include:

[0072] Controlling the second adjustment assembly 6 to shorten, so that the second adjustment rod 62 moves upward in the second adjustment sleeve 61.

[0073] The second adjustment rod 62 drives the upper end of the third L-shaped link 7 to rotate with the inflection point of the third L-shaped link 7 as the center, so that the upper end of the third L-shaped link 7 moves in an arc upward, and the lower end of the third L-shaped link 7 moves in an arc downward.

[0074] The lower end of the third L-shaped link 7 drives the adjustment end 83 of the working component 8 to move in an arc downward. The third L-shaped link 7 mainly plays a role in changing the movement direction. When the second adjustment assembly 6 shortens close to its limit position, the lower end of the third L-shaped link 7 will move in an arc upward, as Figure 2 shown.

[0075] When the first adjustment assembly 3 and the second adjustment assembly 6 work simultaneously, the directions of the third L-shaped link 7 and the fourth link 9 described in this embodiment will change relative to the fixed frame 1, that is, when the first adjustment assembly 3 adjusts a certain angle, at this time, the C-shaped hanger 5 drives the directions of the third L-shaped link 7 and the fourth link 9 to change relative to the fixed frame 1.

[0076] The alignment end 82 of the working component 8 moves in an arc with the fixed end of the fourth link 9 as the center under the constraint of the fourth link 9.

[0077] The adjustment end 83 of the working component 8 makes an arc movement downward under the combined action of the fourth connecting rod 9 and the third L-shaped connecting rod 7, and the alignment end 82 of the working component 8 makes an arc movement under the combined action of the fourth connecting rod 9 and the third L-shaped connecting rod 7. The moving distance of the adjustment end 83 of the working component 8 is greater than the moving distance of the alignment end 82 of the working component 8, so that the working component 8 always aligns with the fixed working point 10 when the angle is increased.

[0078] It should be noted that when the adjustment end 83 of the working component 8 makes an arc movement upward, the alignment end 82 of the working component 8 makes an arc movement upward within a certain range and an arc movement downward within another range. Here, upward or downward generally refers to inclined upward or inclined downward. Since the arc movement is the combined result of two-directional movements, in this embodiment, upward or downward refers to the overall approximate movement direction, so as to clearly understand the approximate movement direction of the adjustment end 83 of the working component 8. At the same time, upward or downward refers to the movement direction when the first adjustment component 3 is in a static state. After determining the approximate movement direction of the adjustment end 83, the angle adjustment direction of the working component 8 can be determined.

[0079] When specifically adjusting the angle of the working component 8 in the present invention, the real-time lengths of the first adjustment rod 31 and the second adjustment rod 62 are calculated according to the positions and lengths of the connecting rods, and then the angle adjustment of the working component 8 is controlled by the telescoping of the first adjustment component 3 and the second adjustment component 6.

[0080] Using the alignment mechanism of the present invention, the two adjustment components cooperate with each other, which can not only change the working angle of the working component 8, but also ensure that the working component 8 aligns with the fixed working point 10 at a fixed position. The two adjustment components are respectively located on both sides of the C-shaped hanger 5. The two adjustment components can cooperate with each other to achieve the purpose of adjusting the angle of the working component 8. Such a structure can reduce the volume of the alignment mechanism and has a large angle adjustment range, so it has strong practicability and is convenient for popularization and use.

[0081] As Figure 3 shown, the fixed working point 10, that is, the O point, is a fixed working point 10 outside the working component 8. The distances between the fixed working point 10 and the reference point on the fixed frame 1, that is, the first fixed point 11, are A and B respectively. When the length of the first adjustment rod 31 is adjusted to C1 and the length of the second adjustment rod 62 is adjusted to D1, the working component 8 aligns with the O point at an angle α1.

[0082] When the length of the first adjustment rod 31 is adjusted to C2 and the length of the second adjustment rod 62 is adjusted to D2, the working component 8 aligns with the O point at an angle α2.

[0083] The alignment mechanism and the working component 8 of the present invention are within the same height range, so the entire alignment mechanism and the working component 8 occupy a small space and have a low height. The present invention forms a connecting rod mechanism by arranging multiple connecting rods, a C-shaped bracket 5, and a telescopic drive component combination, which can achieve the effect of stroke amplification, so that the working component 8 has a larger range of up and down movement, thereby achieving a larger angle adjustment range, and the control process of the mechanism has high reliability and high control accuracy, which can improve the efficiency of the angle adjustment of the working component 8. The present invention avoids the problems of the existing alignment mechanism, that the alignment mechanism occupies a large volume, cannot continuously adjust the angle, and needs to be separated from the fixed frame 1 to adjust the angle.

[0084] In this embodiment, it is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiment, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, no matter from which point of view, the embodiment should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and therefore it is intended that all changes that fall within the meaning and scope of the equivalent elements of the claims are included in the present invention.
