Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Reference Figures 1-3 A blind hole processing device for multilayer boards includes a main seat 1 threaded with bolts. The main seat 1 has a mounting opening 2 at its top, where the multilayer board to be processed is placed. A pair of sliding plates 3 slide horizontally within the mounting opening 2. The two sliding plates 3 can move horizontally and synchronously, facilitating flexible adjustment of the position of a magnet 13 according to the actual length of the multilayer board. A sliding block 4 is fixedly connected to the top of the sliding plate 3. A pair of movable seats 5 slide horizontally on the sliding block 4. The two movable seats 5 adjust their front-to-back position according to the width of the multilayer board, allowing the magnet 13 to adapt to the width of the multilayer board. A fixing plate 6 is provided on the movable seat 5, with the magnet 13 fixed to the bottom of the fixing plate 6. A suction strip 14 is fixed to the top of the sliding plate 3. The magnet 13 and the suction strip 14 are magnetically attracted. The purpose of this arrangement is: 1. The magnetic attraction between the two clamps and fixes the multilayer board on two opposite sides, thereby achieving fixation of the multilayer board. 2. It prevents the movable seats 5 from moving horizontally within the sliding block 4, affecting the clamping and fixing effect on the multilayer board. The material of the suction strip 14 is preferably, but not limited to, high-purity, high-permeability soft iron or nickel-based alloys. These materials have good magnetic properties, can provide stronger attraction, and have good corrosion resistance and mechanical strength, making them suitable for long-term use.
[0021] The main seat 1 is equipped with a drive structure 1 for driving the two slide plates 3 to move horizontally in sync, and the movable seat 5 is equipped with a drive structure 2 for driving the fixed plate 6 to move vertically.
[0022] The drive structure includes a screw sleeve 7 fixedly connected to the bottom surface of the slide plate 3, and a double-acting screw 8 rotatably connected to the main seat 1. The screw sleeve 7 and the double-acting screw 8 are threaded together. The rotation of the double-acting screw 8 drives the two screw sleeves 7 to move synchronously horizontally relative to each other or in opposite directions, thereby causing the slide plate 3 and its components such as the magnet 13 to move synchronously with the screw sleeves 7.
[0023] The top of the slide block 4 has a functional slot, and the movable seat 5 is horizontally slidably connected to the functional slot. A limit groove 18 is provided in the functional slot, and a limit block 9 is fixedly connected to the vertical side wall of the movable seat 5. The limit block 9 and the limit groove 18 are horizontally slidably connected. The limit groove 18 and the limit block 9 are provided to ensure that the movable seat 5 can move stably back and forth horizontally in the functional slot and to prevent the movable seat 5 from falling out of the functional slot.
[0024] The driving structure two comprises an auxiliary groove formed in the top of the moving seat 5, a screw rod 11 is rotationally connected in the auxiliary groove, a sliding port 10 is formed in the moving seat 5, and the sliding port 10 is arranged to ensure that the L-shaped rod 12 can be stably vertically moved along the axial direction of the screw rod 11. The L-shaped rod 12 is threadedly connected to the screw rod 11, the L-shaped rod 12 is vertically slidably connected to the sliding port 10, and the end, away from the screw rod 11, of the L-shaped rod 12 is fixedly connected to the fixed plate 6. The vertical movement of the L-shaped rod 12 drives the fixed plate 6 and the magnet 13 on the fixed plate 6 to be vertically moved.
[0025] One end of the bidirectional screw rod 8 extends to the outside of the main seat 1 and is fixedly connected with a hand wheel 16, the hand wheel 16 is arranged to facilitate the rotation of the bidirectional screw rod 8 by the worker. The mounting port 2 is provided with a sliding groove 15 for facilitating the horizontal sliding of the sliding plate 3. The sliding groove 15 makes the sliding of the sliding plate 3 more smooth and fluent, and makes the worker more convenient when adjusting.
[0026] The main seat 1 is arranged in a "concave" shape, and the "concave" structure not only increases the stability and rigidity of the whole, but also facilitates installation and maintenance. The main seat 1 is fixedly connected with a collecting frame 17 at the bottom, and the collecting frame 17 is arranged directly below the mounting port 2. The collecting frame 17 ensures that the debris generated during the machining process can be effectively collected, keeping the working environment clean.
[0027] The function principle of the utility model can be described by the following operation mode:
[0028] Firstly, the multi-layer plate to be machined is placed on the main seat 1, and it is ensured that it is located in the mounting port 2. At this time, the sliding plate 3 should be in the initial position, that is, in the state of not clamping the multi-layer plate.
[0029] The worker drives the bidirectional screw rod 8 to rotate by rotating the hand wheel 16, and since there is a threaded connection relationship between the screw sleeve 7 and the bidirectional screw rod 8, with the rotation of the bidirectional screw rod 8, the two sliding plates 3 move horizontally in the opposite directions synchronously. When the suction bar 14 at the top of the sliding plate 3 contacts the edge of the multi-layer plate, the hand wheel 16 is continuously rotated until the two ends of the multi-layer plate are located at the top of the two suction bars 14.
[0030] The worker slides the moving seat 5 back and forth in the auxiliary groove according to the actual width of the multi-layer plate, and when the magnet 13 is located directly above the accurately aligned clamping area, the screw rod 11 is screwed, and with the rotation of the screw rod 11, the L-shaped rod 12 threadedly connected thereto will be vertically moved downward until the magnet 13 and the top surface of the multi-layer plate are attached, at this time, the magnet 13 and the suction bar 14 are magnetically attracted, realizing the clamping and fixing of the multi-layer plate, and then the drilling machine is started to complete the machining work of the blind hole.
[0031] After completing the machining of all the predetermined hole positions, the processed multi-layer plate is carefully removed, and at the same time, the worker checks whether there are falling objects or other sundries in the collecting frame 17 to keep the working environment clean.
[0032] The above merely describes a preferred embodiment of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
