[0003] In the electronics manufacturing industry, circuit board drilling is a crucial fundamental process, and its drilling accuracy and efficiency directly affect the performance of electronic products and production efficiency. Currently, most circuit board drilling fixtures widely used in the market adopt a fixed clamping structure, where the circuit board is simply placed in a fixed fixture for drilling. This traditional fixture lacks flexible position adjustment capabilities. When the drilling position needs to be fine-tuned, operators must disassemble and adjust the circuit board again, which not only consumes a lot of time but also easily damages the circuit board, reducing production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a movable fixture for drilling circuit boards, aiming to solve the problem that most widely used circuit board drilling fixtures on the market adopt a fixed clamping structure, where the circuit board is simply placed in a fixed fixture for drilling. This traditional fixture lacks flexible position adjustment function. When the drilling position needs to be finely adjusted, the operator has to disassemble and adjust the circuit board again, which not only consumes a lot of time, but also easily damages the circuit board and reduces production efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a movable fixture for drilling circuit boards, comprising a fixture, wherein a positioning side ear is welded to each of the two sides of the fixture, and two guide rods are symmetrically welded inside the fixture, wherein a fixed plate is fixedly sleeved at one end of the guide rod, and a movable plate is movably sleeved at the other end of the guide rod;

[0006] Two side blocks are fixedly installed on the outer wall of the fixed plate and the movable plate on opposite sides. A movable strip is movably installed between the two side blocks near their upper ends. A fixed strip is provided at the location of the movable strip. The two ends of the fixed strip are fixedly connected to the outer wall of a corresponding side block. Three clamping plates are movably installed on the outer wall of the movable strip and the fixed strip on opposite sides.

[0007] In order to enable the corresponding clamps on the movable strip and the fixed strip to move laterally after clamping the circuit board that needs to be drilled, as a movable fixture for drilling circuit boards according to this utility model, preferably, a sliding groove is opened on the outer wall of the opposite side of the movable strip and the fixed strip, and a moving block is fixedly installed on one side of the clamp.

[0008] The clamping plate is slidably installed inside the slide groove via a moving block.

[0009] In order to effectively fix the drilled circuit board between the movable strip and the fixed strip, as a movable fixture for drilling circuit boards according to this utility model, preferably, two L-shaped grooves are symmetrically opened on one outer wall of the side block, and an L-shaped slider is installed inside each L-shaped groove. The two ends of the movable strip are fixedly connected to the two L-shaped sliders respectively, and the two ends of the movable strip form a sliding connection structure with the L-shaped groove through the corresponding L-shaped sliders.

[0010] A vertical plate is fixedly installed on the top of the side block, and a horizontal plate is welded to one side of the vertical plate. A pressing rod is threaded through the surface of the horizontal plate, and the bottom of the pressing rod presses against the outer wall of the movable strip near one end.

[0011] To ensure that the spacing between the movable plate and the fixed plate can be adapted to the size of the circuit board to be drilled, thereby effectively fixing the circuit board between the movable plate and the fixed plate, as a movable fixture for drilling circuit boards according to this utility model, preferably, two springs are provided on the side of the movable plate away from the fixed plate, each spring is respectively sleeved on the outer wall of a guide rod, and a bearing is fixedly embedded in the outer wall of one side of the center end of the movable plate, and an adjusting rod is welded in the inner ring of the bearing, the adjusting rod being threaded through the side wall of the fixture and connected to the bearing.

[0012] To ensure stability during the movement of the clamping plate, as a movable fixture for drilling circuit boards according to this utility model, preferably, the movable strip and the fixed strip are parallel to each other.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In operation, place the two ends of the circuit board to be drilled between the corresponding movable and fixed strips, and then place the circuit board between the corresponding clamps. Next, adjust the pressing rod downwards. The pressing rod will press the movable strip downwards through the horizontal plate. After the two pressing rods are adjusted, the movable strip will drive the corresponding clamps to hold the circuit board between the movable and fixed strips. At this point, fix the fixture with the positioning ears, and then drill holes in the corresponding areas of the circuit board using the drilling equipment. In addition, during drilling, the fixed circuit board can be moved. When the circuit board moves, it will drive the clamps on both sides to move. When the clamps move, they will move in the slide groove through the corresponding moving blocks. This allows the lateral position of the circuit board to be adjusted appropriately according to the operational requirements.

[0015] In summary, the combination of the above structures makes drilling the circuit board more convenient during use. Attached Figure Description

[0023] 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.

[0024] Please see Figure 1-5 The present invention provides the following technical solution: a movable fixture for drilling circuit boards, including a fixture 1, a positioning side ear 2 welded on each side of the fixture 1, two guide rods 3 symmetrically welded inside the fixture 1, a fixed plate 4 fixedly sleeved at one end of the guide rod 3, and a movable plate 5 movably sleeved at the other end of the guide rod 3.

[0025] Two side blocks 6 are fixedly installed on the outer wall of the opposite side of the fixed plate 4 and the movable plate 5. A movable strip 7 is movably installed between the two side blocks 6 near the upper end. A fixed strip 8 is set at the movable strip 7. The movable strip 7 and the fixed strip 8 are parallel to each other. The two ends of the fixed strip 8 are fixedly connected to the outer wall of a corresponding side block 6. Three clamping plates 9 are movably installed on the outer wall of the opposite side of the movable strip 7 and the fixed strip 8.

[0026] Preferably, a sliding groove 81 is provided on the outer wall of the opposite side of the movable strip 7 and the fixed strip 8, and a movable block 91 is fixedly installed on one side of the clamping plate 9;

[0027] The clamping plate 9 is slidably mounted inside the slide groove 81 via the moving block 91.

[0028] In practical use, when the circuit board is clamped between the two clamping plates 9, pushing the circuit board laterally will cause the corresponding clamping plate 9 to move. When the clamping plate 9 moves, it will cause the moving block 91 to move inside the corresponding slide groove 81, so that the position of the circuit board can be adjusted laterally.

[0029] Preferably, two L-shaped grooves 61 are symmetrically opened on one side outer wall of the side block 6, and an L-shaped slider 62 is installed inside each L-shaped groove 61. The two ends of the movable strip 7 are fixedly connected to the two L-shaped sliders 62 respectively, and the two ends of the movable strip 7 form a sliding connection structure with the L-shaped groove 61 through the corresponding L-shaped sliders 62.

[0030] A vertical plate 63 is fixedly installed on the top of the side block 6. A horizontal plate 64 is welded to one side of the vertical plate 63. A pressing rod 65 is threaded through the surface of the horizontal plate 64. The bottom of the pressing rod 65 presses against the outer wall of the movable strip 7 near one end.

[0031] In practical use, the pressing rod 65 is adjusted downwards via the horizontal plate 64. When the pressing rod 65 moves downwards, it presses against the movable strip 7, causing the movable strip 7 to move downwards. As the movable strip 7 moves downwards, it drives the L-shaped slider 62 to move. When the L-shaped slider 62 moves, it follows the trajectory of the L-shaped groove 61, so that the movable strip 7 can smoothly approach the fixed strip 8, thereby clamping the circuit board.

[0032] Preferably, two springs 51 are provided on the side of the movable plate 5 away from the fixed plate 4. Each spring 51 is respectively sleeved on the outer wall of a guide rod 3. A bearing 52 is fixedly embedded in the outer wall of one side of the center end of the movable plate 5. An adjusting rod 53 is welded in the inner ring of the bearing 52. The adjusting rod 53 is threaded through the side wall of the fixture 1 and docks with the bearing 52.

[0033] In practical use, in order to make the gap between the movable plate 5 and the fixed plate 4 adapt to the length of the corresponding circuit board, the adjusting rod 53 can be adjusted into the fixture 1. When the adjusting rod 53 moves, it will push the movable plate 5 to move through the bearing 52, so that the gap between the movable plate 5 and the fixed plate 4 can be reduced, thus adapting to circuit boards of various sizes.

[0034] When in use, the spring 51 can continuously and stably provide thrust to both ends of the movable plate 5, thus keeping both ends of the movable plate 5 as stable as possible.

[0035] When drilling holes in a circuit board, the two ends of the circuit board to be processed are first placed between the two sets of movable strips 7 and fixed strips 8 of the fixture 1 to form a preliminary position. Then, the circuit board is embedded into the gaps between the corresponding two clamping plates 9, ensuring that the circuit board is horizontal and centered. These clamping plates 9 are made of engineering plastic with high hardness and low coefficient of friction, which can not only firmly hold the circuit board, but also avoid scratching the surface of the circuit board.

[0036] After the initial placement of the circuit board is completed, the fastening operation begins. Slowly adjust the clamping rod 65 downwards. The clamping rod 65, through the horizontal plate 64, applies downward pressure to the movable strip 7. During this process, it is important to maintain consistent adjustment of both clamping rods 65 to ensure even force distribution on the circuit board. The operator can operate one rod with each hand during this step. Once both clamping rods 65 are adjusted to the appropriate positions, the movable strip 7 will drive the clamping plate 9 to firmly hold the circuit board between the movable strip 7 and the fixed strip 8, forming a stable fixing structure. To ensure appropriate clamping force, a torque wrench can be used to assist in adjusting the clamping rod 65, preventing deformation of the circuit board due to excessive pressure or displacement of the circuit board during drilling due to insufficient pressure.

[0037] After the circuit board is fixed, the fixture 1 is installed in the designated position on the drilling equipment using the positioning lug 2, and locked using bolts or quick clamps to ensure that the fixture 1 will not shift during drilling. Then, the drilling equipment can be started to perform drilling operations in the pre-marked area of ​​the circuit board.

[0038] During the drilling process, if it is necessary to fine-tune the lateral position of the circuit board, the fixed circuit board can be moved directly. When the circuit board moves, it will drive the clamping plates 9 on both sides to move synchronously, and the moving block 91 at the bottom of the clamping plate 9 will slide smoothly in the groove 81 of the fixed strip 8.

[0039] In summary, through the coordinated operation of the movable bar 7, the fixed bar 8, the clamping plate 9, and the pressing rod 65, this equipment not only achieves rapid and stable clamping of circuit boards, but also provides flexible position adjustment functions, effectively improving the convenience of circuit board drilling operations.

[0040] The circuit board will be subjected to downward pressure during the drilling process. Therefore, before drilling, a foam board can be laid on the bottom of the circuit board for support, and the support of the foam board can also prevent the circuit board from shifting laterally.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
