Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment, and in particular to a long-stroke movable angular positioning mechanism. Background Technology

[0002] In the production and processing of mechanical parts, angular positioning mechanisms are often used to position the workpiece. Traditional angular positioning mechanisms are all non-movable positioning structures, that is, the angular blocks are usually fixed on the mounting base. This means that when the robotic arm picks up or puts down the workpiece, the angular blocks need to be completely removed from the vertical surface of the workpiece beforehand, which is not conducive to the flexible use of the angular positioning mechanism.

[0003] Furthermore, traditional angular positioning mechanisms typically use hydraulic cylinders to pull the entire mechanism for movement, resulting in excessively long travel distances and hindering the use of angular positioning mechanisms. Additionally, the angular blocks in traditional angular positioning mechanisms are fixed with dead limits, making this type of fixation inconvenient. Therefore, improvements are still needed. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a long-stroke movable angular positioning mechanism, comprising a mounting plate and a telescopic block. A drive cylinder is mounted on the lower end of the mounting plate. A through groove is formed in the center of the mounting plate, through which a connecting rod passes. The end of the connecting rod is connected to the drive cylinder, and a slider is provided at the front end of the connecting rod. A mounting seat is mounted on the upper end of the mounting plate. The mounting seat is a hollow structure, and the slider is installed inside the mounting seat. A rectangular through groove is formed on the front and rear end faces of both the mounting seat and the slider. The telescopic block passes through the rectangular through grooves of the mounting seat and the slider in sequence and slides within the rectangular through grooves of the mounting seat and the slider. An angular block is mounted on the front end of the telescopic block. A pin hole is formed on the telescopic block, and a cotter pin is installed in the pin hole. L-shaped grooves are provided on the left and right sides of the slider, and the cotter pin is installed in the L-shaped grooves.

[0005] Preferably, the bottom surface of the slider is provided with a T-shaped groove, and the front end of the connecting rod is embedded in the T-shaped groove for fixation.

[0006] Preferably, screw washers are placed at both ends of the cotter pin, and a retaining spring is provided between the screw washers and the pin cap of the cotter pin.

[0007] Preferably, the front end of the telescopic block is provided with a molybdenum sheet, and the molybdenum sheet has a through hole for the corner block to pass through.

[0008] Preferably, dustproof plates are installed on both the left and right sides of the mounting base, and a cover plate is installed on the upper end of the mounting base.

[0009] The beneficial effects of this utility model are as follows: The utility model has a reasonable structural design and is practical and convenient. First, by driving the oil cylinder to drive the slider to move up and down, it further drives the corner block to move forward or backward, so that the corner block changes from the original immovable positioning to movable positioning, which improves the ease of use of the corner positioning mechanism and also shortens the stroke length of the driving oil cylinder to drive the corner block. Second, the design of the L-shaped slide groove can meet the long stroke movement of the corner block, and also facilitates the quick fixing of the corner block. Attached Figure Description

[0011] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0012] Unless otherwise stated, any feature in this specification may be replaced by other equivalent or similar features. That is, unless otherwise stated, each feature is merely one example of a series of equivalent or similar features.

[0013] like Figure 1 , 2 The illustrated long-stroke movable angular positioning mechanism includes a mounting plate 12 and a telescopic block 9. A drive cylinder 1 is mounted on the lower end of the mounting plate 12. A through groove is formed in the center of the mounting plate 12, and a connecting rod 11 passes through the through groove. The end of the connecting rod 11 is connected to the drive cylinder 1. A slider 10 is provided at the front end of the connecting rod 11. A mounting seat 2 is mounted on the upper end of the mounting plate 12. The mounting seat 2 is a hollow structure, and the slider 10 is installed in the mounting seat 2. A rectangular through groove is formed on the front and rear end faces of both the mounting seat 2 and the slider 10. The telescopic block 9 passes through the rectangular through grooves of the mounting seat 2 and the slider 10 in sequence and slides in the rectangular through grooves of the mounting seat 2 and the slider 10. An angular block 8 is mounted on the front end of the telescopic block 9. A pin hole is formed on the telescopic block 9, and a cotter pin 6 is installed in the pin hole. L-shaped grooves 13 are provided on the left and right sides of the slider 10, and the cotter pin 6 is installed in the L-shaped grooves 13.

[0014] The bottom surface of the slider 10 is provided with a T-shaped groove, and the front end of the connecting rod 11 is embedded in the T-shaped groove for fixation.

[0015] Screw washers 5 are placed at both the left and right ends of the cotter pin 6, and a retaining spring is provided between the screw washers 5 and the pin cap of the cotter pin 6.

[0016] The front end of the telescopic block 9 is also provided with a molybdenum sheet 4, and the molybdenum sheet 4 has a through hole for the corner block 8 to pass through.

[0017] Dustproof plates 3 are installed on both the left and right sides of the mounting base 2, and a cover plate 7 is installed on the upper end of the mounting base 2.

[0018] During use, the connecting rod 11 is pushed upward by the driving cylinder 1, causing the connecting rod 11 to move the slider 10 upward. During the upward movement of the slider 10, the cotter pin 6 is affected by the upward force of the slider 10 and moves in the L-shaped groove 13, causing the cotter pin 6 to gradually move from the inclined groove section of the L-shaped groove 13 to the vertical groove section of the L-shaped groove 13. During this process, since the cotter pin 6 is inserted in the telescopic block 9, it further drives the telescopic block 9 to gradually extend forward. When the driving cylinder 1 pushes the connecting rod 11 upward to the maximum distance, the cotter pin 6 just moves to the end of the vertical groove section of the L-shaped groove 13, thereby locking the cotter pin 6 in the vertical groove section of the L-shaped groove 13 and fixing it. This allows the telescopic block 9 and the corner block 8 on it to extend forward to the limit position.

[0019] The circlip can stabilize both ends of the cotter pin 6, thereby preventing the cotter pin 6 from wobbling to the left or right, and making the telescopic block 9 more stable when it extends and retracts.

[0020] The mounting base 2 and the slider 10 both have a rectangular through groove on their front and rear ends, which facilitates the placement of the telescopic block 9 and allows the telescopic block 9 to telescopically move within the rectangular through groove, thereby achieving the movable positioning of the corner block 8.

[0021] The beneficial effects of this utility model are as follows: The utility model has a reasonable structural design and is practical and convenient. First, by driving the oil cylinder to drive the slider to move up and down, it further drives the corner block to move forward or backward, so that the corner block changes from the original immovable positioning to movable positioning, which improves the ease of use of the corner positioning mechanism and also shortens the stroke length of the driving oil cylinder to drive the corner block. Second, the design of the L-shaped slide groove can meet the long stroke movement of the corner block, and also facilitates the quick fixing of the corner block.

[0022] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
