Description

Technical Field

[0001] The present application relates to the field of sheet metal processing, and in particular to a sheet metal deep hole processing tool structure. Background Art

[0002] There are two processing methods for sheet metal drilling: one is drill bit rotation and the other is workpiece rotation. The general drilling tools include twist drills, center drills, deep hole drills, etc. Deep hole processing is a common and important process, widely used in many fields such as automobile manufacturing, aerospace, and mechanical equipment;

[0003] Traditional sheet metal deep hole machining tool structures often adopt an integrated design, that is, the tool body and the fixing device are tightly integrated, which makes it difficult to quickly disassemble and replace, affecting production efficiency. In addition, due to the integrated setting, the tool needs to be replaced as a whole after wear, which increases material consumption and cost. Secondly, the cooling system structure is simple, and it is impossible to spray coolant onto the surface of the drill bit in the deep hole during drilling. As a result, the heat generated during the cutting process cannot be effectively removed, resulting in shortened tool life and reduced machining accuracy.

[0004] In view of the above-mentioned related technologies, the inventor believes that the sheet metal deep hole processing tool structure has the defects of being inconvenient to quickly remove and replace the drill bit, and being difficult to effectively cool the drill bit during the drilling process;

[0005] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content

[0007] The present application provides a sheet metal deep hole machining tool structure that adopts the following technical solution:

[0008] A sheet metal deep hole processing tool structure includes a mounting seat, a drill rod is rotatably connected to the lower surface of the mounting seat, a drill bit is engaged and connected to the lower surface of the drill rod, a connecting rod is fixedly connected to the lower surface of the mounting seat, a liquid infusion tube is fixedly connected to the lower surface of the mounting seat, a liquid inlet is fixedly connected to the side surface of the mounting seat, and the liquid inlet is relatively connected to the liquid infusion tube, a liquid spray ring is fixedly connected to the connecting rod and the lower surface of the liquid infusion tube, and the liquid infusion tube and the liquid spray ring are connected to each other.

[0009] Preferably, a clamping groove is provided on the upper surface of the drill bit, and two clamping blocks are fixedly connected to the outer surface of the drill rod, and the two clamping blocks are both clamped and connected to the inner wall of the clamping groove.

[0010] Preferably, two positioning grooves are provided on the lower surface of the drill rod, and two positioning rods are fixedly connected to the inner bottom surface of the clamping groove, and the positioning rods slide relative to the inner wall of the positioning groove.

[0011] Preferably, a support plate is fixedly connected to the inner wall of the mounting seat, a motor is fixedly connected to the upper surface of the support plate, and the upper end of the drill rod is fixedly connected to the output end of the motor.

[0020] The following is combined with Figure 1-3 This application is described in further detail.

[0021] The embodiment of the present application discloses a sheet metal deep hole processing tool structure. Figure 1 、 Figure 2 , including a mounting base 1, so that when the tool structure needs to be used, the mounting base 1 can be fixedly installed at a designated position on the deep hole processing equipment, and a drill rod 2 is rotatably connected to the lower surface of the mounting base 1, and a circular plate-shaped support plate 12 is fixedly connected to the inner wall of the mounting base 1, and a motor 13 is fixedly connected to the upper surface of the support plate 12, and the upper end of the drill rod 2 is fixedly connected to the output end of the motor 13, so that the drill rod 2 is driven to rotate by the motor 13, thereby driving the drill bit 3 to rotate, so as to perform deep hole processing, and the drill bit 3 is engaged with the lower surface of the drill rod 2, so that when deep holes of different diameters need to be processed or the drill bit 3 needs to be repaired and replaced, the drill bit 3 can be quickly disassembled, and then the new drill bit 3 can be quickly engaged with the lower end of the drill rod 2, thereby quickly completing the removal and replacement of the drill bit 3, without replacing the entire tool structure, which not only reduces material consumption but also improves production efficiency;

[0022] Secondly, a cylindrical connecting rod 4 is fixedly connected to the lower surface of the mounting base 1, a tubular infusion tube 5 is fixedly connected through the lower surface of the mounting base 1, a tubular liquid inlet 6 is fixedly connected to the side surface of the mounting base 1, and the liquid inlet 6 is relatively connected to the liquid infusion tube 5, and a spray ring 7 is fixedly connected to the lower surface of the connecting rod 4 and the liquid infusion tube 5, and the liquid infusion tube 5 and the spray ring 7 are connected to each other. By connecting the external coolant pipe to the liquid inlet 6, the coolant can be transported from the liquid inlet 6 to the liquid infusion tube 5 while machining deep holes, and then transported to the spray ring 7, and then sprayed from the various nozzles below the spray ring 7 to the machining area, thereby effectively taking away the heat generated during the drilling process, thereby effectively reducing the tool temperature and thermal deformation of the workpiece, and improving the machining accuracy and tool life.

[0023] Reference Figure 2 A clamping groove 8 is provided on the upper surface of the drill bit 3, and two rectangular clamping blocks 9 are fixedly connected to the outer surface of the drill rod 2, and the two clamping blocks 9 are both clamped and connected to the inner wall of the clamping groove 8, so that the drill bit 3 can be quickly clamped and connected to the lower end of the drill rod 2 by sliding the lower end of the drill rod 2 and the two clamping blocks 9 downward along the inner wall of the clamping groove 8 and then clamping the clamping blocks 9 with the inner wall of the clamping groove 8;

[0024] Two groove-shaped positioning grooves 10 are provided on the lower surface of the drill rod 2, and two columnar positioning rods 11 are fixedly connected to the inner bottom surface of the clamping groove 8, and the positioning rods 11 slide relative to the inner wall of the positioning groove 10, so that when the drill bit 3 is connected to the drill rod 2, the positioning rods 11 slide upward along the inner wall of the positioning groove 10, thereby accurately connecting the drill bit 3 and the drill rod 2 together, so that the drill bit 3 can be subsequently clamped and connected to the lower end of the drill rod 2, thereby improving the accuracy of the connection.

[0025] Reference Figure 3 Two arc-shaped limit grooves 14 are provided on the inner side wall of the card block 9, and groove-shaped installation grooves 15 are provided on the side surfaces of the two card blocks 9. The inner wall of the installation groove 15 is elastically slidably connected with a block-shaped limit block 16 through a spring, and the limit block 16 can be engaged with the inner wall of the limit groove 14, so that the limit block 16 can be pressed to shrink to the inner wall of the installation groove 15, and then when the card block 9 is slid close to the inner bottom surface of the clamping groove 8, due to the disappearance of external force, the limit block 16 will rebound and engage with the inner wall of the limit groove 14 under the resetting action of the spring, thereby stably engaging the card block 9 with the inner wall of the clamping groove 8.

[0026] The implementation principle of a sheet metal deep hole processing tool structure in the embodiment of the present application is as follows: when using the tool structure, the mounting base 1 is fixedly installed at a designated position on the deep hole processing equipment to complete the installation of the tool structure, and then the motor 13 drives the drill rod 2 to rotate, thereby driving the drill bit 3 to rotate, so as to process the deep hole. When drilling, the external coolant delivery pipe delivers the coolant from the liquid inlet 6 to the liquid delivery pipe 5, and then delivers it to the liquid spray ring 7, and then sprays it from the various nozzles below the liquid spray ring 7 to the processing area, thereby effectively taking away the heat generated during the drilling process, thereby effectively reducing the tool temperature and thermal deformation of the workpiece, improving the processing accuracy and tool life, and when deep holes of different diameters need to be processed or the drill bit 3 needs to be repaired and replaced, By pressing the limit block 16 to move it away from the inner wall of the limit groove 14, the drill bit 3 is then moved downward for removal, and then the replaced new drill bit 3 is moved upward, so that the positioning rod 11 slides upward along the inner wall of the positioning groove 10, and then the limit block 16 is pressed to shrink it to the inner wall of the installation groove 15. When the positioning rod 11 slides to the inner top surface of the positioning groove 10, the lower end of the drill rod 2 and the clamping block 9 are both located on the inner wall of the clamping groove 8. At the same time, due to the disappearance of external force, the limit block 16 will rebound and engage with the inner wall of the limit groove 14 under the resetting action of the spring, thereby stably engaging the clamping block 9 with the inner wall of the clamping groove 8, thereby quickly completing the removal and replacement of the drill bit 3, improving production efficiency, and there is no need to replace the entire tool structure, thereby reducing material consumption.
