Technical Field

[0001] The utility model relates to the technical field of equipment for opening holes in diaphragms, in particular to a central hole-opening machine for diaphragms. Background Art

[0002] In the prior art, holes in diaphragms are opened by means of a hammer or manual stamping. The method of using a hammer to open holes, which is an early method, has problems such as poor consistency in the punching positions of the diaphragms and low efficiency. Now, most use the manual stamping method to open holes, and this method has at least the following two problems. First, stamping to open holes will result in more burrs at the hole-opening positions. Second, stamping to open holes will cause the workpieces to be processed to deform or be scratched on their surfaces.

[0003] Therefore, the utility model designs a central hole-opening machine for diaphragms to solve the above problems. Summary of the Utility Model

[0005] The positioning mechanism is composed of a telescopic cylinder, a moving plate, a linear guide rail, a guide rod, a connecting block, a fixed block, a connecting plate, and a positioning plate. The telescopic cylinder is fixedly installed on the mounting seat, the telescopic end of the telescopic cylinder is connected to the moving plate, one end of the moving plate is slidably connected to the linear guide rail, the linear guide rail is fixedly installed on the mounting seat by bolts, connecting blocks are arranged in the guide holes provided at both ends of the moving plate, the connecting blocks are connected to the upper ends of the guide rods, the lower ends of the guide rods are fixedly connected to the fixed block, the fixed block is installed on the connecting plate, and the positioning plate is fixedly installed below the connecting plate.

[0006] The connecting block is composed of a through column, an upper plate, and a lower plate. The top end of the through column is connected to the upper plate, the bottom end of the through column is fixedly connected to the lower plate, the through column is connected through the guide hole provided on the moving plate, the through column is adapted to the guide hole, and the diameters of the upper plate and the lower plate are larger than the diameter of the guide hole.

[0014] Advantages of the utility model:

[0015] When the diaphragm is drilled in the utility model, the diaphragm is placed in the placing groove of the placing seat, and the telescopic air cylinder is started. The telescopic air cylinder controls the moving plate to move downward. The positioning plate connected to the two ends of the moving plate through the guiding rod and the connecting plate moves downward to press the diaphragm to be processed, so as to press and position the diaphragm. At this time, the guiding rod does not move downward with the moving plate any more. The telescopic end of the telescopic air cylinder continues to extend, the moving plate continues to move downward and compresses the spring, and the compression of the spring also makes the pressing force on the diaphragm stronger. The drill bit connected to the output end of the driving motor moves to the through hole of the connecting plate and the positioning hole of the positioning plate, and then slowly moves downward to drill the diaphragm. The telescopic air cylinder not only realizes the control of the downward movement of the positioning plate to press and position the workpiece to be processed, but also realizes the control of the downward movement of the driving motor to open the hole. The overall structure is simple, the operation is convenient, the processing efficiency is improved and the practicability is strong;

[0016] In the utility model, infrared sensors are arranged at both ends of the opening of the protective cover installed on the workbench. When it is detected that an object extends into the workbench, the information signal is transmitted to the externally arranged controller to control the equipment to stop working, so as to avoid safety accidents.

[0025] Embodiment 1

[0026] As Figure 1As shown in the figure, a workbench 2 is fixedly installed on the support frame 1. A protective cover 31 is arranged on the periphery of the workbench 2. Infrared sensors 32 are respectively installed on both sides of the opening arranged on the protective cover 31. A placing seat 4 is connected to the workbench 2. A placing groove is arranged on the placing seat 4 for placing the diaphragm to be processed. A mounting seat 5 is fixedly installed on the workbench 2 beside the placing seat 4 by bolts. The mounting seat 5 is connected to a driving motor 7 through a positioning mechanism. The output end 7 of the driving motor is connected to a hole-opening knife 8.

[0027] As Figures 2-4 , in the positioning mechanism, a telescopic cylinder 61 is fixedly installed on the mounting seat 5. The telescopic end of the telescopic cylinder 61 is connected to a moving plate 62. One end of the moving plate 62 is slidably connected to a linear guide rail 621. The linear guide rail 621 is fixedly installed on the mounting seat 5 by bolts. Connecting blocks are arranged in the guiding holes arranged at both ends of the moving plate 62. The connecting block is composed of a through column 641, an upper plate 642 and a lower plate 643. The top end of the through column 641 is connected to the upper plate 642. The bottom end of the through column 641 is fixedly connected to the lower plate 643. The through column 641 is connected through the guiding hole arranged on the moving plate 62. The through column 641 is adapted to the guiding hole, and the diameters of the upper plate 642 and the lower plate 643 are larger than the diameter of the guiding hole. The upper end of a guiding rod 63 is connected to the through column 642. The lower end of the guiding rod 63 is fixedly connected to a fixed block 65. A spring 68 is arranged on the outer side of the guiding rod 63. The fixed block 65 is installed on a connecting plate 66. A positioning plate 67 is fixedly installed below the connecting plate 66.

[0028] Among them, the hole-opening knife 8 is located above the through hole arranged on the connecting plate 66. The through hole arranged on the connecting plate 66 corresponds to the positioning hole arranged on the positioning plate 67. The placing seat 4 is located below the positioning plate 67. The center point of the placing seat 4 corresponds to the center of the positioning hole of the positioning plate 67.

[0029] It should be noted that the telescopic cylinder 61, the driving motor 7, the infrared detection sensor 32 and the control buttons installed on the support frame 1 in the present utility model are all electrically connected to a controller arranged outside to control the start and operation of the equipment.

[0030] Embodiment 2

[0031] When using the utility model for drilling, first place the diaphragm into the placement groove of the placement seat 4, and then start the telescopic cylinder 61. The telescopic cylinder 61 controls the downward movement of the moving plate 62. The positioning plates 67 connected to both ends of the moving plate 62 through the guide rods 63, connecting blocks, and connecting plates 66 move downward. The positioning plate 67 moves down above the diaphragm, and the positioning plate 67 presses the diaphragm to be processed. After the positioning plate 67 presses the diaphragm, the guide rods 63 no longer move downward with the moving plate 62. The telescopic end of the telescopic cylinder 61 continues to extend, causing the moving plate 62 to continue to move downward, compressing the spring 68. The compression of the spring 68 makes the pressing on the diaphragm tighter. The continuous downward movement of the moving plate 62 causes the drilling cutter 8 connected to the output end of the driving motor 7 to move into the through hole 661 on the connecting plate 66 and the positioning hole on the positioning plate 67, and slowly move downward to drill the diaphragm. The overall structure is simple, the operation is convenient, the processing efficiency is improved, and the practicability is strong;

[0032] During the drilling process, if an operator reaches in through the open end of the protective cover 31, the infrared sensors 32 installed on both sides of the opening detect the object and immediately transmit information to the controller set outside to control the entire device to stop working, avoiding safety accidents.
