Description

Technical Field

[0001] The present invention belongs to the technical field of machining, and particularly relates to a multi-directional positioning and stabilizing device for drilling plates in machining. Background Art

[0002] In the field of modern machining, drilling plates is a common and crucial operation. Whether it is manufacturing aerospace components, automobile body parts, or the casings of various electronic devices, precise drilling of plates is required to meet subsequent assembly or functional requirements. With the rapid development of the industry, higher requirements have been put forward for the quality, efficiency, and safety of plate drilling.

[0003] A Chinese patent application with the publication number CN213496688U discloses a plate drilling device for large-scale machining, including a fixed seat, a limiting mechanism, a driving mechanism, and a drilling mechanism. Two groups of symmetric sliding grooves are opened at the top of the fixed seat, and a plurality of groups of equally spaced adjustment holes are drilled on both sides of the fixed seat near the sliding grooves. Two groups of symmetric clamping plates are arranged above the fixed seat, solving the problem that the existing plate drilling device for large-scale machining cannot be well adjusted as needed during use.

[0004] However, the following problems still exist in the implementation of the above device: For example, during the fixation of the plate, only by moving two groups of clamping plates and cooperating with bolts to fix the plate, the contact area with the plate is small and the clamping force is uneven. During drilling, the plate is prone to shaking, resulting in deviations in the position, diameter, and pitch of the holes, affecting the machining accuracy and product performance. It also takes time to adjust the clamping, reducing the production efficiency. The high-speed debris generated during drilling lacks effective protection, is easy to injure the operator, and endangers safety; moreover, the scattered debris affects the machining environment, interferes with the operation of other equipment, and increases the cleaning and maintenance costs.

[0005] Therefore, we provide a multi-directional positioning and stabilizing device for drilling plates in machining to solve the above problems. Summary of the Invention

[0040] Example 3

[0041] Please refer to Figures 1 - 10, on the basis of Embodiment 1 and Embodiment 2, an adjustment hole 31 is provided inside the connecting rod 24. There are four connecting rods 24, and three adjustment holes 31 are provided inside each connecting rod 24. When the two sets of limiting plates 5 move relative to each other to fix the workpiece, the position of the limiting plate 5 can be adjusted by rotating the bolt rod 33, which is convenient for fixing workpieces of different widths. A connecting shell 32 is provided through one side of the adjustment hole 31. A bolt rod 33 is threadedly connected inside the connecting shell 32. One side of the connecting shell 32 is fixedly connected to the limiting plate 5. One side of the first toothed plate 14 is fixedly connected to the clamping plate 4. The bottom height of the scraping plate 12 is flush with the top height of the workpiece. A reset block 34 is fixedly connected to one side of the first toothed plate 14.

The cross bar 37 is used to improve the stability of the horizontal movement of the second toothed plate 22. Both sides of the cross bar 37 are fixedly connected to the inner wall of the processing table 1. A second spring 38 is sleeved on the surface of the cross bar 37. The second spring 38 can reset the second toothed plate 22. A second hydraulic rod 39 is installed on one side of the first hydraulic rod 2. The second hydraulic rod 39 is used to drive the drilling machine 3 to move back and forth to adjust the position of the plate drilling. A column 40 is fixedly connected between the second hydraulic rod 39 and the processing table 1. A collection shell 41 is fixedly connected to the front side of the processing table 1. The collection shell 41 is used to collect the waste chips scraped by the scraping plate 12, which is convenient for the staff to clean up centrally. A limit pin 42 is installed on the top of the collection shell 41. The limit pin 42 is installed on the top of the collection shell 41 to limit the position of the scraping plate 12.

[0042] The working principle of the present invention is as follows: The staff places the workpiece on the top of the processing table 1, and then starts the double-shaft motor 16. The double-shaft motor 16 drives the moving sleeve 18 to move in cooperation with the screw rod 17. The moving sleeve 18 drives the moving shell 6 to move in cooperation with the connecting block 19. While the moving shell 6 is moving, it cooperates with the tension spring 35, the reset block 34 and the first toothed plate 14 to push the clamping plate 4 to move. When the two sets of clamping plates 4 move relative to each other, the workpiece can be pushed towards the middle position of the processing table 1, and the workpiece is firmly clamped from both sides by the clamping plate 4.

[0043] Then continue to start the double-shaft motor 16 to drive the moving shell 6 to move. The moving shell 6 drives the support shaft 7 and the first gear 13 to move. At this time, the position of the first toothed plate 14 remains unchanged under the action of the clamping plate 4. When the moving shell 6 continues to move, the first toothed plate 14 can drive the first gear 13 to rotate. The first gear 13 drives the rotating rod 8 and the pressing plate 9 to rotate in cooperation with the support shaft 7. When the pressing plate 9 rotates, it contacts the workpiece, and the top of the workpiece is firmly clamped by the pressing plate 9.

[0044] While the movable shell 6 moves, it drives the push plate 15 to move. The push plate 15 pushes the reset rod 25 to move. The reset rod 25 cooperates with the connecting rod 24 to drive the limiting plate 5 to move. When the two groups of limiting plates 5 move, they can firmly clamp the workpiece from the front side and the rear side of the workpiece, further improving the clamping stability of the workpiece, effectively avoiding the shaking of the plate workpiece during drilling, and improving the processing stability of the workpiece.

[0045] While the pressing plate 9 rotates, it drives the protective cover 10 to move to the top of the workpiece, covering the processing position of the workpiece, which can avoid the splashing of debris during the drilling of the workpiece and improve the protection effect.

[0046] After that, start the first hydraulic rod 2 and the drilling machine 3 to drill the plate workpiece. After the drilling is completed, the double-shaft motor 16 can be controlled to rotate in the reverse direction, driving the two groups of clamping plates 4 to move in the opposite direction to release the clamping of the plate workpiece. When the double-shaft motor 16 drives the two groups of moving sleeves 18 to move in the opposite direction, it can drive the connecting plate 20 to move. When the connecting plate 20 contacts the moving plate 23, it can push the second toothed plate 22 to move and squeeze the second spring 38. The second toothed plate 22 drives the second gear 21 to rotate. The second gear 21 cooperates with the rotating shaft 11 to drive the scraper 12 to rotate. When the scraper 12 rotates, it contacts the top of the plate workpiece, scrapes the waste chips on the surface of the plate workpiece, and discharges them into the collection shell 41, which is convenient for the staff to clean up centrally and improves the processing effect of the plate workpiece.

[0047] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
