Description

Technical Field

[0001] This utility model relates to the field of hole-opening equipment technology, specifically a hole-opening mechanism for hinge production. Background Technology

[0002] Hinges, also known as hinges, are mechanical devices used to connect two solid objects and allow relative rotation between them. They are used in the lock bodies of mining machines, engineering vehicles, or aerial work platforms. During the production of hinges, holes need to be drilled, which requires the use of drilling equipment.

[0003] A search revealed a patent, CN211218774U, which discloses a positioning and drilling device for hinge processing. This device includes a frame with a collecting mechanism and a positioning mechanism fixedly mounted on its top. In this device, a fixing rod is inserted into a clamping housing. Rotating the handwheel moves the threaded block to the left, which in turn moves the top block to the left via a bearing, fixing the fixing rod between the clamping block and the top block. A material plate is placed on the hole-fixing mechanism. Turning on the switch moves the material plate to the appropriate position. The drive mechanism rotates the drill bit mechanism, and the positioning mechanism positions the drill bit mechanism, allowing the drilling drill to punch a hole in the material plate. Observing the scale, the descent of the positioning mechanism can be adjusted. The drill bit has a graduated plate for calibration to eliminate errors.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned prior art documents use a hole-fixing mechanism to position the hinge to be drilled. However, in reality, hinges come in a variety of styles, and the locations where holes need to be drilled also vary. Therefore, the hole-drilling equipment described in the prior art documents has a limited applicability when drilling holes in hinges. Consequently, there is an urgent need in the art to improve the hole-drilling mechanism used in hinge production, thereby overcoming the shortcomings of the prior art. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-8A hole-opening mechanism for hinge production includes a processing box 1, a processing cavity 2 inside the processing box 1, a hole-opening unit 3 that can be moved and used for hole opening in the upper part of the processing cavity 2, and a placement platform 4 for placing the workpiece to be opened on the bottom of the processing cavity 2 and one side of the processing box 1. The two placement platforms 4 are fixedly connected to each other on opposite sides, and side plates 5 are fixedly connected to the opposite sides of the placement platforms 4. The opposite sides of the processing box 1 are provided with moving openings 6 that are adapted to the side plates 5. The upper surface of the placement platform 4 is provided with two symmetrical clamping plates 7. The opposite sides of the two placement platforms 4 are connected to each other. Each of the two clamping plates 7 is fixedly installed with a first drive motor 8 for driving the two clamping plates 7 to move towards or away from each other. A second drive motor 9 is fixedly installed on one side of a placement platform 4. A threaded screw 10 penetrating the machining box 1 is fixedly installed at the output end of the second drive motor 9. The threaded screw 10 is threadedly connected to the machining box 1. The opening unit 3 includes a movable seat 14 slidably connected to the top wall of the machining cavity 2. A telescopic device 11 with a telescopic effect is slidably connected to the lower side of the movable seat 14. A third drive motor 12 is fixedly installed at the lower end of the telescopic device 11. A drilling bit 13 for drilling is fixedly installed at the lower end of the output 12. A first sliding block 15 is fixedly installed on the upper side of the moving base 14. A first sliding groove 16 adapted to the first sliding block 15 is opened in the top wall of the machining cavity 2. A first lead screw 17 threadedly connected to the first sliding block 15 is rotatably connected in the first sliding groove 16. A fourth drive motor 18 with its output end fixedly installed at one end of the first lead screw 17 is fixedly installed on one side of the machining box 1. A second sliding block 19 is fixedly installed at the upper end of the telescopic device 11. A groove for drilling is opened on the lower side of the moving base 14. The second sliding groove 20 is adapted to the second sliding block 19. The second sliding groove 20 is rotatably connected to the second lead screw 21, which is threadedly connected to the second sliding block 19. The fifth drive motor 22, whose output end is fixedly installed at one end of the moving seat 14, is fixedly installed at the end of the second lead screw 21. The moving block 23 is fixedly installed on the lower side of the clamping plate 7. The upper surface of the placement platform 4 is provided with a moving groove 24 adapted to the moving block 23. The bidirectional lead screw 25, which is threadedly connected to the moving block 23, is rotatably connected to the moving groove 24. One end of the bidirectional lead screw 25 is fixedly installed at the output end of the corresponding first drive motor 8.

[0031] Specifically, when drilling holes in the hinge, the hinge is placed on the upper surface of a placement platform 4 located outside the processing box 1. The first drive motor 8 on the side of the placement platform 4 is started. The output end of the first drive motor 8 drives the bidirectional lead screw 25 to rotate. The threads of the bidirectional lead screw 25 located on the inner side of the moving groove 24 are symmetrical and opposite. When the bidirectional lead screw 25 rotates, it drives two moving blocks 23 to move towards each other in the moving groove 24. The moving blocks 23 drive the clamping plates 7 to move. The two clamping plates 7 move towards each other and clamp and fix the hinge. Then, the second drive motor 8 is started. The output of the second drive motor 9 drives the threaded screw 10 to rotate. The threaded screw 10 is threadedly connected to the processing box 1. Therefore, when the threaded screw 10 rotates, it drives the two placement tables 4 to move in the moving port 6, moving the placement table 4 holding the hinge into the processing cavity 2. The side plate 5 is adapted to the moving port 6 to block it. At this time, the hinge on the other placement table 4 that has been moved to the outside can be taken out or placed. By starting the fourth drive motor 18, the output of the fourth drive motor 18 drives the first screw 17 to rotate. When the first screw 17 rotates... The first sliding block 15 is driven to move within the first sliding groove 16, causing the moving seat 14 to move horizontally. Simultaneously, the fifth drive motor 22 is activated, and its output drives the second lead screw 21 to rotate. When the second lead screw 21 rotates, it drives the second sliding block 19 to move within the second sliding groove 20. The second sliding block 19 then drives the telescopic device 11 to move horizontally and vertically. At the same time, the telescopic device 11 is activated, and its telescopic end drives the third drive motor 12 to move downwards. The third drive motor 12 is then activated. The output end of 2 drives the drilling bit 13 to rotate. The drilling bit 13 drills holes in the clamped hinge. It can drill holes at any position on the hinge, thereby improving the applicability of the overall device. By setting two placement platforms 4, the device can drill holes in the hinge while picking up and putting down the hinge, improving the efficiency of the overall drilling device in drilling the hinge. At the same time, when the width of the hinge is wide, one hinge can be clamped on one placement platform 4. If the width of the hinge is narrow, two or more hinges can be clamped on one placement platform 4 at the same time, improving the drilling efficiency of the overall device.

[0032] As a technical optimization of this utility model, a plurality of chip removal grooves 26 are provided through the upper surface of the placement table 4, and a connecting groove 27 adapted to the chip removal grooves 26 is provided at the bottom of the processing cavity 2. A collection box 29 that can be pulled out and located below the processing cavity 2 is inserted into one side of the processing box 1, and a through groove 28 is provided through the bottom of the moving groove 24 through the placement table 4.

[0033] Specifically, when clamping the hinge, make sure to align the position on the hinge where the hole needs to be drilled with the position of the chip removal groove 26. The iron filings generated when drilling the hinge will fall into the collection box 29 through the chip removal groove 26 and the connecting groove 27 for collection. This facilitates the collection of iron filings generated when drilling the hinge. At the same time, when a placement table 4 moves to the outside of the processing box 1 or when the clamping plate 7 moves, the iron filings in the moving groove 24 will fall to the outside through the through groove 28 to prevent the moving block 23 from getting stuck.

[0034] As a technical optimization of this utility model, an observation window 30 is embedded on the front side of the processing box 1. The observation window 30 is transparent, and the drilling of the hinge can be observed in real time through the transparent observation window 30.
