DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0033] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] Example 1: See Figure 1-Figure 4 The present invention provides a technical solution: an adjustable drilling device for agricultural machinery production and processing, comprising a bottom plate 1, a workbench 4 is fixedly connected to the middle end of the top of the bottom plate 1, a support plate 2 is fixedly connected to the side of the top of the bottom plate 1 away from the workbench 4, and a drilling mechanism 3 is fixedly connected to the side of the support plate 2 close to the workbench 4, and also includes:

[0035] The supporting mechanism 5 includes a slider 501, the bottom of the slider 501 contacts the top of the base plate 1, the top of the slider 501 is fixedly connected with a connecting rod 502, the side of the connecting rod 502 away from the slider 501 is fixedly connected with a fitting block 503, the outer wall of the connecting rod 502 is provided with a fixing block 504, the inner wall of the fixing block 504 is fixedly connected to the outer wall of the connecting rod 502, the side of the fixing block 504 close to the workbench 4 is fixedly connected with two groups of curved plates 506, the two groups of curved plates 506 are fixedly connected with a first telescopic rod 507 on the side away from the fixing block 504, the two groups of first telescopic rods 507 are fixedly connected with a pushing block 508 on the side away from the curved plate 506, the pushing blocks 508 are provided with holes on the sides close to each other, and at this time, when the pushing blocks 508 come into contact with the parts, the holes are compressed to push the parts. The block 508 fits the part more closely, and a fixing ring 505 is provided on the side of the fixing block 504 close to the slider 501. The side of the fixing ring 505 close to the pushing block 508 is rotatably connected to a rotating rod 509 through a first rotating shaft. The side of the rotating rod 509 close to the pushing block 508 is fixedly connected to the bottom of the pushing block 508, and a pull rope 510 is fixedly connected to the bottom of the rotating rod 509. The side of the pull rope 510 away from the rotating rod 509 is fixedly connected to a gravity ball 511. By setting the gravity ball 511, the rotating rod 509 can be continuously pulled down by the falling force of the gravity ball 511, so that the pushing force of the pushing block 508 on the part can be guaranteed by the rotating rod 509. The supporting mechanism 5 is provided in two groups and are symmetrically provided with the middle part of the base plate 1 as the center. The pushing block 508 is used to straighten the mechanical parts.

[0036] The working principle of this embodiment is as follows: when drilling holes in agricultural machinery, the worker first places the part to be drilled on the workbench 4. For parts with irregular shapes, they may tilt to one side after being placed. At this time, the tilted part will push the push block 508 to move it away from the part. The movement of the push block 508 will press the first telescopic rod 507 to shrink it. The thrust generated by the shrinkage of the first telescopic rod 507 will push the curved plate 506 to move, thereby driving the curved plate 506 to push the fixed block 504. After the fixed block 504 is subjected to force, the top fitting block 503 and the bottom fixing ring 505 are driven by the connecting rod 502 to move. The slider 501 moves synchronously. At the same time, when the pushing block 508 moves, it will drive the rotating rod 509 at the bottom to rotate at an angle. During the rotation of the rotating rod 509, the pull rope 510 at the bottom will be shaken. The shaking force of the pull rope 510 will swing the gravity ball 511 with a heavier mass at the bottom. When the gravity ball 511 shakes, a downward pulling force is generated, which pulls the pull rope 510 downward, thereby driving the rotating rod 509 to rotate downward. In this way, when the rotating rod 509 rotates again, it will push the pushing block 508 to move in the opposite direction, pushing the inclined parts to move to the middle of the workbench 4, so that it is in a vertical state. At this time, the bonding block 503 will also contact the parts to support the parts.

[0037] Example 2: Please refer to Figure 5-Figure 7On the basis of the first embodiment, the present invention provides a technical solution: it also includes a limiting mechanism 6, which includes a base 601, a side of the base 601 close to the workbench 4 is fixedly connected to a sliding rod 603, a side of the sliding rod 603 close to the base 601 is fixedly connected to the base 601, a first spring 602 is arranged on the outer wall of the sliding rod 603, the first spring 602 contacts the sliding rod 603, the first spring 602 is used to pull the slider 501 to approach each other, the side of the first spring 602 close to the slider 501 is fixedly connected to the slider 501, the inner wall of the slider 501 is slidably connected to the outer wall of the sliding rod 603, a side of the base 601 close to the sliding rod 603 is fixedly connected to a moving ring 604, a side of the moving ring 604 close to the sliding rod 603 is fixedly connected to a second telescopic rod 605, the sliding rod 603 is used to limit the moving trajectory of the slider 501, and the second telescopic rod 605 is far A moving block 607 is fixedly connected to one side away from the moving ring 604, and arc rods 608 are fixedly connected to both sides of the moving block 607. Insert rods 606 are fixedly connected to the tops of the two groups of arc rods 608. The second telescopic rod 605 is used to adjust the distance between the moving block 607 and the moving ring 604. The two groups of arc rods 608 are rotatably connected to a hook plate 609 through a second rotating shaft on one side away from the second telescopic rod 605. The slider 501 can be restricted by setting the hook plate 609, so as to ensure that the slider 501 does not move after the slider 501 completes the movement. The base 601, the moving ring 604, the second telescopic rod 605, the moving block 607, the two groups of arc rods 608, the insert rod 606 and the group hooks are all arranged in two groups and are symmetrically arranged with the middle of the sliding rod 603 as the center. The hook plate 609 is used to limit the movement of the slider 501.

[0038] The working principle of this embodiment is as follows: when the slider 501 slides on the slide rod 603, the slider 501 will stretch the first spring 602. As the slider 501 continues to slide, it will contact the hook plate 609 and exert a large thrust on it, causing the hook plate 609 to rotate one circle and contact the slider 501 again. At the same time, the slider 501 will also push the moving block 607 to move. During the movement, the moving block 607 will push the second telescopic rod 605 to contract, thereby shortening the distance between the moving block 607 and the moving ring 604. When the moving block 607 moves, it will drive the insertion rod 606 at its top to move synchronously. At this time, the first spring 602 will generate a reverse pulling force on the slider 501, and the hook plate 609 will briefly hold the slider 501 to play a limiting role. It is worth noting that the hook plate 609 and the moving block 607 are connected by a bearing and can only rotate in the clockwise direction.

[0039] Example 3: Please refer to Figure 8-Figure 9On the basis of the first and second embodiments, the present invention provides a technical solution: it also includes a fixing mechanism 7, the fixing mechanism 7 includes two groups of positioning blocks 701, the bottoms of the two groups of positioning blocks 701 are fixedly connected to the top of the base 601, the inner walls of the two groups of positioning blocks 701 are provided with contact rods 702, the positioning blocks 701 are used to limit the moving distance of the insertion rod 606, the upper and lower ends of the two groups of contact rods 702 are fixedly connected to the inner walls of the positioning blocks 701, the outer walls of the two groups of contact rods 702 are in contact with the second springs 704, the two groups of second springs 704 are fixedly connected to the side away from the positioning blocks 701 with the lower pressing plate 705, and the lower pressing plate 705 is close to the A pressing block 706 is fixedly connected to one side of the positioning block 701, and the second spring 704 is used to pull the lower pressure plate 705 to move. The bottom of the lower pressure plate 705 is in contact with a rotating block 703 on the side away from the pressing block 706. By setting the pressing block 706, the insertion rod 606 can be pressed downward after the movement is completed, thereby ensuring that the insertion rod 606 cannot move again when subjected to downward pressure. The rotating block 703 is rotatably connected to the two groups of positioning blocks 701 through a third rotating axis. The fixing mechanism 7 is set to two groups, and they are all symmetrically set with the middle of the base plate 1 as the center. The rotating block 703 is used to prevent the insertion rod 606 from continuing to move.

[0040] The working principle of this embodiment is as follows: when the insertion rod 606 starts to move toward the positioning block 701 driven by the moving block 607, as the insertion rod 606 continues to move, it will contact the rotating block 703, and the continued movement of the insertion rod 606 will push the rotating block 703 to rotate. When the rotating block 703 rotates to the same horizontal position as the insertion rod 606, the protrusion on the top of the rotating block 703 will insert into the inner wall of the insertion rod 606. At the same time, as the rotating block 703 continues to rotate, it will press the lower pressure plate 701. 05 disappears, the tension on the second spring 704 decreases, and it starts to rebound and pull the lower pressure plate 705 downward. The lower pressure plate 705 slides downward on the contact rod 702. When the insertion rod 606 completes the movement, the downward movement of the lower pressure plate 705 drives the pressing block 706 to move downward together. The pressing block 706 contacts the inner wall of the insertion rod 606 and applies a downward pressing force to the insertion rod 606 under the tension of the second spring 704, thereby fixing the insertion rod 606.
