Detailed Implementation
[0022] 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.
[0023] Example 1
[0024] Please see Figures 1 to 6This utility model provides a technical solution: a circuit board milling clamping device, including a support box 1. Two limiting posts 3 are fixedly connected inside the support box 1. Two sliding rings 301 are slidably connected outside the limiting posts 3. A connecting plate 302 is fixedly connected outside the two sliding rings 301. An mounting plate 401 is fixedly connected to the adjacent side of the two connecting plates 302. Two limiting plates 4 are slidably connected inside the mounting plate 401. A sliding groove 402 is formed inside the mounting plate 401. The limiting plates 4 are slidably connected inside the sliding groove 402, and the outer side of the limiting plates 4 contacts the outer side of the connecting plates 302. A fixing plate 403 is fixedly connected outside the limiting plates 4. A sliding groove 404 is formed on the top of the fixing plate 403. A fixing post 6 is fixedly connected outside the connecting plate 302. A driving assembly is fixedly connected to the adjacent side of the two fixing posts 6. 601, the fixed plate 403 is externally fixedly connected to two limiting blocks 703, the limiting block 703 is internally rotatably connected to a rotating plate 702, the rotating plate 702 is externally rotatably connected to a limiting block 701, the limiting block 701 is externally fixedly connected to an internal threaded block 7, and the fixed plate 403 is externally fixedly connected to a placement plate 8. When encountering a small circuit board, the motor 602 inside the drive assembly 601 is started. The motor 602 drives the bidirectional threaded rod 603 to rotate. The two internal threaded blocks 7 outside the bidirectional threaded rod 603 move towards each other under the action of thread transmission. The internal threaded blocks 7 pull the fixed plate 403 through the limiting block 701, the rotating plate 702 and the limiting block 703, so that the distance between the two fixed plates 403 is reduced, thereby adjusting the size of the clamping device to adapt to the clamping requirements of smaller circuit boards.
[0025] Support columns 101 are fixedly connected to the four corners of the bottom of the support box 1, and a top cover 102 is fixedly connected to the top of the support box 1. The four support columns 101 are fixedly connected to the four corners of the bottom of the support box 1 to support and fix the device on the working plane, ensuring the stability of the device during processing and preventing shaking or displacement.
[0026] The top cover 102 is equipped with a processing component 2, and a processing head 201 is fixedly connected to the bottom of the processing component 2. The processing component 2 is installed inside the top cover 102 and the processing head 201 is fixedly connected to the bottom. It is the core component for realizing the milling of circuit board grooves. The milling operation is completed by driving the processing head 201 to move.
[0027] A limiting component 5 is slidably connected inside the sliding groove 404, and a pressure plate 501 is fixedly connected to the top of the limiting component 5. The pressure plate 501 is fixedly connected to the top of the limiting component 5. By sliding inside the sliding groove 404, the pressure plate 501 is moved to limit the top of the circuit board and prevent the circuit board from shifting during processing.
[0028] The drive assembly 601 has a motor 602 fixedly connected inside, and a bidirectional threaded rod 603 fixedly connected to the output end of the motor 602. A limit piece 604 is fixedly connected to the outside of the bidirectional threaded rod 603. The motor 602 drives the bidirectional threaded rod 603 to rotate, thereby adjusting the spacing of the fixing plate 403 to meet the clamping requirements of circuit boards of different sizes.
[0029] A vertical plate 8010 is fixedly connected to the top of the placement plate 8. A rotating groove 801 is formed inside the vertical plate 801. A retaining plate 802 is rotatably connected inside the rotating groove 801. A retaining slot 803 is formed inside the retaining plate 802. An installation groove 804 is formed outside the retaining slot 803. A pressing plate 805 is rotatably connected inside the installation groove 804. A U-shaped plate 806 is fixedly connected to the outside of the retaining plate 802. Two telescopic rods 807 are fixedly connected inside the U-shaped plate 806. Springs 808 are sleeved on the outside of the telescopic rods 807. A push plate 809 is connected; when processing the circuit board, first insert one end of the circuit board into the slot 803 of the clamping plate 802, and then rotate the circuit board to make it flat on the top of the placement plate 8. When the circuit board is inserted into the slot 803, it will push the pressing plate 805. At the same time, the telescopic rod 807 and the spring 808 apply a pushing force to the rear side of the pressing plate 805 through the push plate 809, so that the pressing plate 805 generates a clamping force on the circuit board under the action of the spring 808, preventing the circuit board from loosening in the slot 803, and completing the initial fixation of the circuit board.
[0030] The working principle of this utility model is as follows: When processing the circuit board, simply insert one end of the circuit board into the slot 803, then rotate the circuit board to place it on top of the placement plate 8, and then slide the limiting component 5 so that the limiting component 5 cooperates with the pressure plate 501 to limit the top of the circuit board, and then push it to the bottom of the top cover 102. When pushing, the circuit board will cooperate with the placement plate 8 and the connecting plate 302 to slide outside the limiting post 3 through the sliding ring 301, and then the processing component 2 cooperates with the sliding ring 301 to process the circuit board.
[0031] Then, when encountering a smaller circuit board, simply start the motor 602 inside the drive assembly 601, so that the motor 602 drives the bidirectional threaded rod 603 to rotate, and then cause the two internal threaded blocks 7 outside the bidirectional threaded rod 603 to move towards each other. Then, the internal threaded blocks 7, together with the first limiting block 701 and the rotating plate 702, pull the fixed plate 403 through the second limiting block 703, thereby reducing the distance between the two fixed plates 403, thus making it suitable for the size of the circuit board.
[0032] Example 2
[0033] Please see Figures 4 to 5In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that when the circuit board is placed into the slot 803, in order to make the circuit board more stable, when the circuit board slides into the slot 803, it will first push the pressing plate 805. At the same time, the telescopic rod 807 and the spring 808 push the rear side of the pressing plate 805 through the pushing piece 809. Then the circuit board pushes the pressing plate 805. The pressing plate 805 will also generate a clamping force on the circuit board through the spring 808. This can prevent the circuit board from loosening inside the slot 803.
