Technical Field

[0001] The utility model relates to the field of polycarbonate plate processing, and particularly relates to a precise drilling mechanism for polycarbonate plates. Background Art

[0002] The polycarbonate plate is also known as the PC plate. At present, due to its unique properties, the polycarbonate plate is widely used in many fields, especially in the construction field. However, when installing and using it, it is generally necessary to drill installation holes or holes for other purposes in advance.

[0003] Since the installation position and installation fixing points are generally fixed, when drilling holes in advance, it is necessary to accurately drill holes according to the installation points to ensure the accurate position of the holes so that they can be aligned during installation.

[0004] Currently, the most common way to drill holes is to select a suitable drill bit and drill holes through a drilling machine. However, the drill bit models are generally universal, and the size specifications of each universal drill bit model are generally fixed. Therefore, the holes drilled by these drill bits may not be exactly the same as the hole diameters required for installation, especially for some larger holes.

[0005] In addition, when drilling holes through a drilling machine, generally one hole is drilled at a time. If the demand for polycarbonate plates of the same specification for installation is large and the number of holes to be drilled is very large, the drilling efficiency through the drilling machine is very low, and it is also very difficult to ensure the accuracy of the position and size of each hole when drilling one hole at a time. Content of the Utility Model

[0006] In view of this, the purpose of the present utility model is to provide a precise drilling mechanism for polycarbonate plates to solve the technical problems that when the demand for polycarbonate plates of the same specification is large, the drilling efficiency through a drilling machine is very low and it is very difficult to ensure the accuracy of the position and size of each hole in the prior art.

[0010] Further, the drilling cutter is cylindrical, and a cutting edge is chamfered at the bottom end of the cylindrical drilling cutter. The inner diameter of the drilling groove is larger than the outer diameter of the drilling cutter.

[0011] Further, a plurality of the drilling cutters and the drilling grooves are provided, and the centers of a corresponding set of the drilling cutters and the drilling grooves are on the same vertical line.

[0012] Further, a top plate is slidably connected inside the drilling cutter, and a spring is further provided inside the drilling cutter. The upper and lower ends of the spring are respectively connected to the stamping seat and the top plate.

[0025] Specific implementation manners and principles

[0026] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the following further elaborates on the present utility model in conjunction with specific embodiments.

[0027] It should be noted that unless otherwise defined, the technical terms or scientific terms used in the present utility model should have the ordinary meanings understood by those with ordinary skills in the field to which the present utility model belongs. The "first", "second" and similar terms used in the present utility model do not indicate any sequence, quantity or importance, but are only used to distinguish different components.

The terms such as "connected" or "coupled" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. The terms such as "upper", "lower", "left", "right", etc. are only used to indicate relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0028] In the first aspect of the present utility model, as Figure 1 and Figure 2 shown, in order to be able to drill holes in batches for polycarbonate plates of the same specification, and at the same time to ensure that the positions and sizes of each drilled hole are accurate, an equipment main body 101 is provided, and a hydraulic press is provided inside the equipment main body 101. A stamping seat 104 is arranged below the equipment main body 101. The stamping seat 104 is fixedly connected to the lower end of the telescopic shaft 103 of the hydraulic press, and a drilling cutter 105 is also fixedly connected to the lower end of the stamping seat 104.

[0029] To cooperate with the use of the drilling cutter 105, a base 102 is provided below the stamping seat 104. On the upper end surface of the base 102, a positioning placement groove is provided according to the size and shape of the polycarbonate sheet. After the polycarbonate sheet to be processed is placed in the positioning placement groove, it fits exactly. In addition, a drilling groove 106 that cooperates with the drilling cutter 105 is also provided in the positioning placement groove.

[0030] By providing a positioning placement groove on the upper end surface of the base 102 according to the size and shape of the polycarbonate sheet, not only can the polycarbonate sheet be fixed, but also the position of the polycarbonate sheet during drilling is ensured to be accurate, thereby ensuring the accuracy of the drilled hole positions.

[0031] The key point is that, as Figure 3 and Figure 4 shown, the drilling cutter 105 is set to be cylindrical, and the bottom end of the cylindrical drilling cutter 105 is chamfered to form a cutting edge. In addition, the inner diameter of the drilling groove 106 is larger than the outer diameter of the drilling cutter 105. A DC power supply 109 is also provided in the stamping seat 104, and a heating wire is provided in the side wall of the drilling cutter 105. The heating wire is connected to the DC power supply 109, and the DC power supply 109 supplies power to the heating wire. The heating wire generates heat and transfers the heat to the drilling cutter 105, so that the drilling cutter 105 always maintains a high temperature state.

[0032] Therefore, by setting the drilling cutter 105 to be cylindrical and chamfering the bottom end of the cylindrical drilling cutter 105 to form a cutting edge, and then cooperating with the DC power supply 109 to heat the drilling cutter 105, the drilling cutter 105 drills more smoothly and the cut holes are very smooth.

[0033] Specifically, the outer diameter of the drilling cutter 105 is set according to the size of the required hole, and according to the number and positions of the holes required on each polycarbonate sheet, the number and positions of the drilling cutter 105 and the drilling groove 106 are set in advance, and the centers of a corresponding group of the drilling cutter 105 and the drilling groove 106 are on the same vertical line. Then, in cooperation with the polycarbonate sheet with a determined position, all the required holes can be accurately drilled at one time.

[0034] On the other hand, as Figure 3 shown, a blanking bin 107 is also provided in the base 102. The lower end of the drilling groove 106 communicates with the blanking bin 107, and a drawable receiving drawer 108 is also provided in the blanking bin 107. The inner diameter of the drilling groove 106 is larger than the outer diameter of the drilling cutter 105. During drilling, the drilling cutter 105 can pass through the polycarbonate sheet and enter the drilling groove 106, without suspending the polycarbonate sheet, ensuring the stability of the polycarbonate sheet during drilling, and not worrying about the drilling cutter 105 colliding with the base 102.

[0035] The lower end of the drilling groove 106 is connected to the drop bin 107, so that the cut scraps can fall into the drilling groove 106 and finally fall into the material receiving drawer 108 in the drop bin 107, which is convenient for waste collection and unified processing.

[0036] Preferably, in order to prevent the cut scraps from getting stuck in the drilling cutter 105, they will fall smoothly into the drilling slot 106. Figure 4 As shown, a top plate 110 is slidably connected in the drilling cutter 105 , and a spring 111 is also provided in the drilling cutter 105 , and the upper and lower ends of the spring 111 are respectively connected to the punching seat 104 and the top plate 110 .

[0037] Therefore, when drilling, the part at the hole position can squeeze the top plate 110 and the spring 111 into the inside of the drilling cutter 105. After the drilling is completed, the spring 111 acts on the top plate 110 to rebound, pushing the cut scraps out of the drilling cutter 105 again. Since the drilling cutter 105 is still in the drilling groove 106 at this time, the cut scraps will fall through the drilling groove 106 into the receiving drawer 108 in the drop bin 107. DETAILED DESCRIPTION

[0038] Before drilling, first place the polycarbonate plate into the positioning groove on the base 102 and ensure that the polycarbonate plate is exactly stuck in the positioning groove.

[0039] After the above preparations are completed, the hydraulic press in the main body 101 of the equipment is started, and the hydraulic press drives the punching seat 104 to descend through the telescopic shaft 103. Since the lower end of the punching seat 104 is also fixedly connected to the drilling cutter 105, the drilling cutter 105 will descend and finally fall on the polycarbonate plate, cutting holes at corresponding positions on the polycarbonate plate.

[0040] The DC power supply 109 supplies power to the heating wire so that the drilling cutter 105 always maintains a high temperature state. The bottom end of the drilling cutter 105 is chamfered to produce a cutting edge, so that the hole is drilled smoothly and the cut hole is ensured to be very smooth.

[0041] When drilling, the portion at the hole position can squeeze the top plate 110 and the spring 111 into the interior of the drilling cutter 105. After the drilling is completed, the spring 111 acts on the top plate 110 to rebound, pushing the cut scraps out of the drilling cutter 105 again. Since the drilling cutter 105 is still in the drilling groove 106 at this time, the cut scraps will fall through the drilling groove 106 into the receiving drawer 108 in the drop bin 107, and the waste materials will be collected and processed uniformly.

[0042] After all the required holes are precisely drilled in one go on this polycarbonate sheet, restart the hydraulic press inside the main body 101 of the device. The hydraulic press drives the stamping seat 104 to rise through the telescopic shaft 103, then take out the polycarbonate sheet after drilling, place the next sheet to be processed into the positioning placement groove on the base 102, and repeat the above operations.

[0043] Based on the above, the present utility model sets the drilling cutter 105 in a cylindrical shape, and a cutting edge is chamfered at the bottom end of the cylindrical drilling cutter 105. Together with the DC power supply 109 heating the drilling cutter 105, it makes the drilling process of the drilling cutter 105 smoother and the cut holes very smooth. And a positioning placement groove is provided on the upper end surface of the base 102 according to the size and shape of the polycarbonate sheet. At the same time, the outer diameter of the drilling cutter 105 is set according to the size of the required holes, and according to the number and positions of the holes required on each polycarbonate sheet, the number and positions of the drilling cutters 105 are set in advance, so that all the required holes can be precisely drilled in one go in cooperation with the polycarbonate sheet with a determined position. In addition, a drilling groove 106 is provided on the base 102 corresponding to the hole positions, and a top plate 110 and a spring 111 are arranged inside the drilling cutter 105. During drilling, the corresponding part can enter the inside of the drilling cutter 105 to reduce the obstruction and ensure smooth drilling. And the finally cut scraps can fall into the drilling groove 106 under the push of the spring 111 and the top plate 110, which is convenient for waste collection.
