Description
Technical Field
[0001] This utility model belongs to the field of circuit board processing technology, and specifically relates to a circuit board slot hole processing device. Background Technology
[0002] Circuit board (PCB) fabrication is a complex manufacturing process that transforms design drawings into usable printed circuit boards. It involves multiple steps such as material handling, pattern transfer, machining, and chemical treatment. Circuit board slot and hole processing equipment is a key piece of equipment used to process non-circular holes (such as long slots, square slots, etc.) on printed circuit boards (PCBs). Its design must take into account accuracy, efficiency, and reliability.
[0003] Existing circuit board slot processing devices work by placing the circuit board to be processed in a processing slot, and then using a motor to drive a double-acting lead screw to rotate, which in turn moves a movable table threaded to the lead screw. A pneumatic or hydraulic chuck is mounted on the movable table, and a tungsten carbide or diamond-coated milling cutter is installed using this chuck. The slot is then processed by moving the table while the milling cutter rotates. However, in actual use, when processing different types and specifications of circuit boards, it is necessary to change the circuit board placement slot. This process requires tightening a certain number of screws, which is cumbersome, time-consuming, and labor-intensive, causing problems for the circuit board slot processing. Utility Model Content
[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a circuit board slot processing device that can quickly adapt to different types of circuit boards for clamping and fixing, facilitating slot processing on different types of circuit boards.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a circuit board slot hole processing device, including a hole-opening seat, a hole-opening seat with uniformly distributed clearance grooves on its upper surface, a symmetrically distributed guide rail inside the hole-opening seat, a symmetrically distributed sliding seat slidably disposed between the guide rails, a uniformly distributed support on the sliding seat, a rotating shaft rotatably disposed between adjacent supports, a symmetrically distributed rotating shaft 2 rotatably disposed inside the sliding seat, a driven rod fixedly sleeved in the middle of the outer arc surface of the rotating shaft 1, and the rotating shaft 2... A rotating rod is fixedly sleeved in the middle of the outer arc surface. The ends of the rotating rod and the driven rod on the same side away from the sliding seat are rotatably connected to a clamping block. A placement plate is provided in the middle of the upper surface of the hole seat. A bracket is provided on the upper surface of the hole seat. An XYZ axis linear slide is provided at the upper end of the bracket. A drilling table is provided on the XYZ axis linear slide. A milling cutter is provided on the drilling table. A worktable is provided on the lower surface of the hole seat. Symmetrically distributed door panels are rotatably mounted on the front side of the worktable. Evenly distributed support legs are provided on the lower surface of the worktable.
[0006] As a further improvement of this utility model, a rotating rod is rotatably arranged in the center of the sliding seat. The rotating shaft is fixed to the adjacent rotating rod by a coupling. A worm gear is fixedly sleeved in the center of the outer arc surface of the rotating rod. A worm is rotatably arranged in the lower side of the sliding seat. The worm is meshed with the adjacent worm gear. A rotating seat is arranged in the center of the opening seat. A spline cylinder is rotatably arranged on the rotating seat. A symmetrically distributed spline is slidably arranged inside the spline cylinder. The spline is fixed to the adjacent worm by a coupling. A helical gear is fixedly sleeved on the outer arc surface of the spline cylinder. A motor seat is arranged inside the opening seat. A motor is arranged on the motor seat. A helical gear is fixedly sleeved on the output shaft of the motor. The helical gear is fixed to the helical gear.
[0007] As a further improvement of this utility model, a bidirectional lead screw is rotatably arranged inside the opening seat, and the sliding seats are all threadedly connected to the bidirectional lead screw. A motor is arranged on the outside of the opening seat, and the output shaft of the motor is fixed to the bidirectional lead screw by a coupling.
[0008] As a further improvement of this utility model, a control box is provided on the hole-opening seat, and the XYZ axis linear slide, drilling table, motor one and motor two are all electrically connected to the control box.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0010] Firstly, the interaction between the rotating rod and the driven rod drives the clamping blocks on both sides to rotate downwards synchronously. The parallelogram structure formed by the rotating rod and the driven rod drives the clamping blocks to move downwards stably. Under the meshing relationship between the worm and the worm wheel, the circuit board on the placement plate is quickly and stably clamped and fixed.
[0011] Secondly, the output shaft of motor two drives helical gear two connected to it to rotate. Through the meshing relationship between helical gear two and helical gear one, the spline cylinder where helical gear one is located is driven to rotate, so that the spline cylinder drives the worm gears on both sides to rotate through the spline, thereby driving the rotating rods and driven rods on both sides to rotate synchronously and stably.
[0012] Third, the output shaft of motor one drives the bidirectional lead screw connected to it to rotate. Through the threaded relationship between the bidirectional lead screw and the sliding seat, the sliding seats on both sides move towards each other or away from each other, thereby adjusting the position of the sliding seats and facilitating stable adjustment of the clamping position.
[0013] Fourth, the interior space of the workbench can be opened by pulling the door panel, allowing for the storage of necessary tools within the workbench. Attached Figure Description

Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.
[0021] like Figure 2 , 3As shown, the device includes an opening seat 104. The upper surface of the opening seat 104 has evenly distributed clearance grooves 201. The interior of the opening seat 104 is provided with symmetrically distributed guide rails 202. Symmetrically distributed sliding seats 203 are slidably arranged between the guide rails 202. Evenly distributed supports 204 are provided on the sliding seats 203. A first rotating shaft 205 is rotatably arranged between adjacent supports 204. A second rotating shaft 206 is rotatably arranged inside the sliding seat 203. A driven rod 208 is fixedly sleeved in the middle of the outer arc surface of the first rotating shaft 205. A driven rod 208 is fixedly sleeved in the middle of the outer arc surface of the second rotating shaft 206. A rotating rod 207 is fixedly mounted. The ends of the rotating rod 207 and the driven rod 208 located on the same side away from the sliding seat 203 are rotatably connected to a clamping block 209. A placement plate 108 is provided in the middle of the upper surface of the opening seat 104. A rotating rod is rotatably mounted in the middle of the interior of the sliding seat 203. The rotating shaft 206 is fixed to the adjacent rotating rod 207 by a coupling. A worm gear 212 is fixedly mounted in the middle of the outer arc surface of the rotating rod 207. A worm 213 is rotatably mounted in the lower interior of the sliding seat 203. The worm 213 is meshed with the adjacent worm gear 212.
[0022] like Figure 1 , 4 As shown, a bracket 105 is provided on the upper surface of the hole holder 104, an XYZ axis linear slide 106 is provided at the upper end of the bracket 105, a drilling table is provided on the XYZ axis linear slide 106, and a milling cutter 107 is provided on the drilling table.
[0023] like Figure 3 , 4 As shown, a rotating seat 214 is provided in the center of the opening seat 104. A splined cylinder 215 is rotatably mounted on the rotating seat 214. A symmetrically distributed spline 216 is slidably mounted inside the splined cylinder 215. The spline 216 is fixed to the adjacent worm gear 213 by a coupling. A helical gear 217 is fixedly sleeved on the outer arc surface of the splined cylinder 215. A motor seat 218 is provided inside the opening seat 104. A motor 219 is mounted on the motor seat 218. A helical gear 219 is fixedly sleeved on the output shaft of the motor 219. The helical gear 219 is fixed to the helical gear 217 by a coupling. A double-acting lead screw 210 is rotatably mounted inside the opening seat 104. The sliding seats 203 are all threadedly connected to the double-acting lead screw 210. A motor 211 is provided on the outer side of the opening seat 104. The output shaft of the motor 211 is fixed to the double-acting lead screw 210 by a coupling.

[0025] In use, the circuit board requiring slot processing is placed on the placement plate 108. The control box 301 controls the operation of motor 211, causing the output shaft of motor 211 to drive the connected bidirectional lead screw 210 to rotate. Through the threaded relationship between the bidirectional lead screw 210 and the sliding seat 203, the sliding seats 203 on both sides move towards each other or away from each other, thus adjusting the position of the sliding seats 203. The control box 301 also controls the operation of motor 219, causing the output shaft of motor 219 to drive the connected helical gear 2 to rotate. The meshing relationship between the second gear and the first helical gear 217 causes the splined cylinder 215 where the first helical gear 217 is located to rotate, so that the splined cylinder 215 drives the worm gears 213 on both sides to rotate through the spline 216. The meshing relationship between the worm gears 213 and the worm wheel 212 drives the rotating rod where the worm wheel 212 is located to rotate, so that the rotating rod drives the rotating shafts 206 on both sides to rotate. Then, through the cooperation between the rotating rod 207 and the driven rod 208, the clamping blocks 209 on both sides rotate downward synchronously, so as to quickly and stably clamp and fix the circuit board on the placement plate 108.
[0026] The XYZ axis linear slide 106 and drilling table are controlled by the control box 301, which causes the XYZ axis linear slide 106 to drive the rotating milling cutter 107 to move and perform slot processing on the circuit board.
[0027] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, a workbench 101 is provided on the lower surface of the opening seat 104.
