Description

Technical Field

[0001] This application belongs to the field of alignment mechanism technology, and specifically relates to an adjustable-angle alignment mechanism. Background Technology

[0002] In mechanical mechanisms, there are often situations where working parts need to be aligned with a fixed working point along a straight line, but the alignment angle needs to be adjusted. In such cases, the working parts are usually held by an alignment mechanism, which is mounted on a fixed bracket.

[0003] When the fixed working point is far from the fixed frame, the alignment mechanism needs to travel a large distance and occupy a significant amount of space. Therefore, this type of alignment mechanism is often limited by the overall machine size, resulting in a small angle adjustment range. Some alignment mechanisms also have the problem of not being able to continuously adjust the angle. Furthermore, some alignment mechanisms are detached from the fixed frame during operation, and need to be reattached after adjustment, which can be inconvenient for larger machines.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances.

[0041] like Figures 1 to 10 As shown, the adjustable-angle alignment mechanism provided in this embodiment of the invention includes a working component 8, a C-shaped bracket 5, a fixing frame 1, a first connecting rod 2, a first adjusting rod 31, a first adjusting sleeve 32, and a second connecting rod 4.

[0042] The mounting bracket 1 is fixedly installed and is located on one side of the opening of the C-type bracket 5. The working part 8 is installed below the C-type bracket 5.

[0043] The fixed end of the first link 2 and the fixed bracket 1 are hinged at the first fixed point 11. The movable end of the first link 2 and the C-shaped bracket 5 are hinged at the first hinge point 51.

[0044] The end of the first adjusting rod 31 and the fixing frame 1 are hinged at the second fixing point 12. The first adjusting sleeve 32 is telescopically fitted onto the first adjusting rod 31, and the middle 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 fixing point 12.

[0045] The fixed end of the second link 4 and the fixed bracket 1 are hinged at the third fixed point 13. The movable end of the second link 4 is hinged at the second hinge point 52 of the C-shaped bracket 5.

[0046] The second hinge point 52 is located below the first hinge point 51.

[0047] It should be noted that 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 bracket 5. The fixed frame 1 is the fixed base of this mechanism, and all parts are directly or indirectly mounted on the fixed frame 1 through the linkage mechanism. The first adjusting assembly 3 includes the first adjusting rod 31 and the first adjusting sleeve 32.

[0048] When the angle of the working component 8 is increased, the first adjusting sleeve 32 is controlled to move upward on the first adjusting rod 31. The first adjusting sleeve 32 drives the first connecting rod 2 to rotate around the fixed end of the first connecting rod 2, i.e., the first fixed point 11, as the center. This causes the movable end of the first connecting rod 2, i.e., the first hinge point 51, to move upward in an arc. In this embodiment, the arc movement refers to the movement trajectory being an arc. The movable end of the first connecting rod 2, i.e., the first hinge point 51, drives the upper end of the C-shaped bracket 5 to move upward in an arc. At the same time, the middle part of the C-shaped bracket 5, constrained by the second connecting rod 4, moves upward in an arc around the fixed end of the second connecting rod 4, i.e., the third fixed point 13, as the center. The C-shaped bracket 5 moves upward in an arc under the combined action of the first connecting rod 2 and the second connecting rod 4. The C-shaped bracket 5 drives the adjusting end 83 of the working component 8 below it to move upward in an arc around the fixed working point 10, and the aligning end 82 of the working component 8 moves downward in an arc, thereby achieving the movement mode in which the working component 8 is always aligned with the fixed working point 10 when the angle is increased.

[0049] When the angle of the working component 8 is reduced, the first adjusting sleeve 32 is moved downward on the first adjusting rod 31, and the C-shaped bracket 5 moves downward in an arc under the combined action of the first connecting rod 2 and the second connecting rod 4. The C-shaped bracket 5 drives the adjusting end 83 of the working component 8 below it to move downward in an arc around the fixed working point 10, and the alignment end 82 of the working component 8 moves upward in an arc, thus achieving the movement mode in which the working component 8 is always aligned with the fixed working point 10 when the angle is reduced. When the C-shaped bracket 5 moves downward in an arc, the C-shaped bracket 5 undergoes changes in its vertical position, its horizontal position, and its angle relative to the fixed frame 1. This mechanism can adjust the alignment angle of the working component 8 of the equipment with a fixed working point 10 outside the equipment.

[0050] like Figure 5 As shown, in this embodiment, one end of the first adjusting rod 31 is fitted with a first adjusting sleeve 32, and the other end of the first adjusting rod 31 is hinged to a support 33, which is fixed to the fixing frame 1. A spherical bearing is provided between the end of the first adjusting rod 31 and the support 33.

[0051] One end of the adjusting inner rod 34 passes through the first adjusting sleeve 32 and is threaded 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. The first adjusting sleeve 32 and the positioning block 36 are connected.

[0052] It should be noted that rotating the inner adjusting rod 34, since the inner adjusting rod 34 and the first adjusting rod 31 are threadedly connected, and the end of the first adjusting rod 31 is hinged to the second fixed point 12, causes the inner adjusting rod 34 and the first adjusting rod 31 to move relative to each other. The first adjusting sleeve 32 is connected to the positioning block 36, causing the first adjusting rod 31 and the first adjusting sleeve 32 to move relative to each other, thereby realizing the movement mode of the first adjusting sleeve 32 on the first adjusting rod 31, thus realizing the telescopic function.

[0053] like Figure 6 As shown, one end of the first connecting rod 2 is rotatably connected to the pin 20 of the C-shaped bracket 5, and a self-lubricating bearing 30 is provided at the end of the first connecting rod 2 and at the pin 20 of the C-shaped bracket 5. The other end of the first connecting rod 2 is rotatably connected to the pin 20 of the fixed frame 1, and a self-lubricating bearing 30 is provided at the end of the first connecting rod 2 and at the pin 20 of the fixed frame 1. An end cap 40 is provided at the end of the pin 20 of the fixed frame 1.

[0054] like Figure 7 As shown, one end of the second connecting rod 4 is rotatably connected to the pin 20 of the fixed frame 1. A self-lubricating bearing 30 is provided at the end of the second connecting rod 4 and at the pin 20 of the fixed frame 1. An end cap 40 is provided at the end of the pin 20 of the fixed frame 1. The other end of the second connecting rod 4 is rotatably connected to the pin 20 of the C-shaped bracket 5. The end of the second connecting rod 4 is located between the two side panels 59 of the C-shaped bracket 5. A self-lubricating bearing 30 is provided at the end of the second connecting rod 4 and at the pin 20 of the C-shaped bracket 5.

[0055] In this embodiment, the third fixing point 13 is located diagonally below the second fixing point 12 and close to the side of the C-shaped bracket 5.

[0056] In this embodiment, the C-shaped bracket 5 includes an upper rod 56, a middle rod 57, and a lower rod 58 connected in sequence, forming a C-shaped structure. The first hinge point 51 is located at the end of the upper rod 56. The second hinge point 52 is located at the upper part of the middle rod 57.

[0057] In this embodiment, the second adjusting rod 62 is telescopically fitted inside the second adjusting sleeve 61, and the middle part of the second adjusting sleeve 61 and the C-shaped bracket 5 are hinged at the third hinge point 53.

[0058] The third L-shaped connecting rod 7 has an L-shaped structure, and the inflection point of the third L-shaped connecting rod 7 and the C-shaped bracket 5 are hinged 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 bracket 5 away from the fixed frame 1.

[0059] 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.

[0060] The upper end of the fourth link 9 and the C-shaped bracket 5 are hinged at the fifth hinge point 55. The fifth hinge point 55 is located at the end of the lower link 58.

[0061] The alignment end 82 of the working part 8 and the lower end of the fourth link 9 are hinged at the ninth hinge point 81.

[0062] The adjusting 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. The eighth hinge point 72 and the fixed working point 10 are located on both sides of the ninth hinge point 81.

[0063] It should be noted that when the angle of the working component 8 is increased, the second adjusting rod 62 is controlled to move downward within the second adjusting sleeve 61. The second adjusting rod 62 drives the upper end of the third L-shaped connecting rod 7, i.e., the seventh hinge point 71, to rotate around the inflection point of the third L-shaped connecting rod 7, i.e., the fourth hinge point 54, causing the upper end of the third L-shaped connecting rod 7 to move downward in an arc, and the lower end of the third L-shaped connecting rod 7, i.e., the eighth hinge point 72, to move upward in an arc. The lower end of the third L-shaped connecting rod 7, i.e., the eighth hinge point 72, drives the adjusting end 83 of the working component 8 to move upward in an arc. Under the constraint of the fourth connecting rod 9, the alignment end 82 of the working component 8 moves in an arc around the fixed end of the fourth connecting rod 9, i.e., the fifth hinge point 55, as the center. The movable end of the fourth connecting rod 9, i.e., the ninth hinge point 81, is hinged to the alignment end 82 of the working component 8. The adjusting end 83 of the working component 8 moves upward in an arc under the combined action of the fourth link 9 and the third L-shaped link 7, and the aligning end 82 of the working component 8 also 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 adjusting end 83 of the working component 8 is greater than the moving distance of the aligning end 82 of the working component 8, so that the working component 8 is always aligned with the fixed working point 10 when the angle is increased.

[0064] When the adjusting end 83 of the working component 8 moves upward in an arc, the aligning end 82 of the working component 8 moves upward in an arc within a certain range and downward in an arc within another range. Here, "upward" or "downward" generally refers to tilting upward or downward. Since the arc movement is the result of movement in two directions, in this embodiment, "upward" or "downward" refers to the approximate overall movement direction, making it easier to clearly understand the approximate movement direction of the adjusting end 83 of the working component 8. Once the approximate movement direction of the adjusting end 83 is determined, the angle adjustment direction of the working component 8 can be determined. In this invention, when adjusting the specific angle of the working component 8, the position and length of each connecting rod are converted into the real-time lengths of the first adjusting rod 31 and the second adjusting rod 62, and then the angle adjustment of the working component 8 is controlled by the extension and retraction of the first adjusting assembly and the second adjusting assembly.

[0065] When the angle of the working component 8 is reduced, the second adjusting rod 62 is moved upward within the second adjusting sleeve 61, causing the adjusting end 83 of the working component 8 to move downward in an arc under the combined action of the fourth connecting rod 9 and the third L-shaped connecting rod 7. The aligning end 82 of the working component 8 also moves in an arc under the combined action of the fourth connecting rod 9 and the third L-shaped connecting rod 7. The moving distance of the adjusting end 83 of the working component 8 is greater than the moving distance of the aligning end 82, ensuring that the working component 8 is always aligned with the fixed working point 10 when the angle is reduced.

[0066] Using the alignment mechanism of this invention, the two adjustment components cooperate with each other to change the working angle of the working part 8 while ensuring that the working part 8 is aligned with the fixed working point 10 in a fixed position. The two adjustment components are located on both sides of the C-shaped bracket 5, and they can cooperate with each other to achieve the purpose of adjusting the angle of the working part 8. This structure can reduce the size of the alignment mechanism while having a large angle adjustment range, thus it is highly practical and easy to promote and use.

[0067] The third L-shaped link 7 mainly serves to change the direction of motion. When the second adjusting component 6 is shortened to near its limit position, the lower end of the third L-shaped link 7 will move upward in an arc, such as... Figure 2 As shown.

[0068] like Figure 8 As shown, the second adjusting sleeve 61 is the cylinder body of the driving cylinder, and the second adjusting rod 62 is the piston rod of the driving cylinder.

[0069] The second adjusting sleeve 61 has pins 20 on both sides, and the pins 20 pass through holes in the wall plate 59 of the C-shaped bracket 5. A self-lubricating bearing 30 is provided between the pins 20 and the holes in the C-shaped bracket 5. The end of the second adjusting rod 62 is rotatably connected to the pin 20 of the third L-shaped connecting rod 7, and a self-lubricating bearing 30 is provided at the end of the second adjusting rod 62 and at the pin 20.

[0070] like Figure 9 As shown, the inflection point of the third L-shaped connecting rod 7 is rotatably connected to the pin 20 on the C-shaped bracket 5, and a self-lubricating bearing 30 is provided between the inflection point of the third L-shaped connecting rod 7 and the pin 20. The end of the third L-shaped connecting rod 7 is rotatably connected to the pin 20 on the working part 8, and a self-lubricating bearing 30 is provided between the end of the third L-shaped connecting rod 7 and the pin 20 on the working part 8.

[0071] like Figure 10 As shown, one end of the fourth link 9 is rotatably connected to the pin 20 on the C-type bracket 5, and a self-lubricating bearing 30 is provided between the end of the fourth link 9 and the pin 20 on the C-type bracket 5. The other end of the fourth link 9 is rotatably connected to the pin 20 on the working part 8, and a self-lubricating bearing 30 is provided between the end of the fourth link 9 and the pin 20 on the working part 8.

[0072] In this embodiment, the third hinge point 53 is located at the connection between the upper member 56 and the middle member 57.

[0073] In this embodiment, the third L-shaped connecting rod 7 includes an upper inclined rod 73 and a lower inclined rod 74 connected to each other, with the upper inclined rod 73 and the lower inclined rod 74 forming a set angle.

[0074] The fourth hinge point 54 is located at the connection between the upper inclined member 73 and the lower inclined member 74. The end of the second adjusting rod 62 and the end of the upper inclined member 73 are hinged at the seventh hinge point 71. The adjusting end 83 of the working part 8 and the end of the lower inclined member 74 are hinged at the eighth hinge point 72.

[0075] like Figure 3 As shown, fixed working point 10, or point O, is a fixed working point 10 outside the working component 8. The distances of fixed working point 10 relative to the reference point on the fixed frame 1, i.e., the first fixed point 11, are A and B, respectively. When the length of the first adjusting rod 31 is adjusted to C1 and the length of the second adjusting rod 62 is adjusted to D1, the working component 8 is aligned with point O at an angle α1.

[0076] When the length of the first adjusting rod 31 is adjusted to C2 and the length of the second adjusting rod 62 is adjusted to D2, the working part 8 is aligned with point O at an angle α2.

[0077] When the first adjustment component and the second adjustment component work simultaneously, the directions of the third L-shaped link 7 and the fourth link 9 described in this embodiment will change relative to each other. That is, when the first adjustment component is adjusted to a certain angle, the direction of the third L-shaped link 7 and the fourth link 9 relative to the fixed frame is changed by the C-shaped bracket 5.

[0078] The alignment mechanism and working component 8 of this invention are within the same height range, thus the entire alignment mechanism and working component 8 occupy little space and have a low height. This invention, by setting up multiple connecting rods, a C-shaped bracket 5, and a telescopic drive component to form a linkage mechanism, can achieve a stroke amplification, giving the working component 8 a larger vertical movement range, thereby achieving a larger angle adjustment range. Furthermore, this mechanism has high reliability and high control precision, improving the efficiency of angle adjustment for the working component 8. This invention avoids the problems of existing alignment mechanisms, such as large volume, inability to continuously adjust angles, and the need to detach from the fixed bracket 1 to adjust the angle.

[0079] In this embodiment, it will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of the equivalents of the claims be included within the present invention.
