Description

Technical Field

[0001] The utility model relates to the technical field of metal processing and drilling, in particular to a drilling device for metal processing. Background Art

[0002] Metal is a substance with certain hardness, high ductility, easy thermal and electrical conductivity. Due to its certain hardness, metal is often used to manufacture mechanical parts. Usually, during the processing and production of metal parts, in order to cooperate with subsequent use, it is necessary to use a drilling device to punch holes on the surface of the metal parts. Metal pipes are one of the common metal parts.

[0003] When drilling holes in metal pipes with conventional drilling devices, the drill bit is prone to slipping due to the relatively smooth surface of the metal pipe, which can easily cause scratches on the surface of the metal pipe. At the same time, for some metal pipes with thinner walls, deformation is prone to occur during drilling. Therefore, a metal processing drilling device is urgently needed to solve the above problems. Utility Model Content

[0004] Based on the deficiencies in the prior art mentioned in the above background technology, the utility model provides a drilling device for metal processing.

[0005] The utility model overcomes the above technical problems by adopting the following technical solutions, specifically:

[0006] A drilling device for metal processing comprises a body, a drill bit and a workbench, wherein a tube body is arranged on the top of the workbench;

[0007] A positioning assembly for fixing the pipe body is provided on the top of the workbench;

[0008] The positioning assembly includes a positioning seat fixedly connected to the outer wall of the top of the workbench, a movable seat is provided on the top of the workbench, one end of the tube body is pressed against the inner wall of one side of the positioning seat, a mounting groove is opened on the outer wall of the top of the workbench, a threaded screw is rotatably connected to the inner wall of one side of the mounting groove, a threaded sleeve is engaged with the circumferential outer wall of the threaded screw, a guide rod is fixedly connected to the inner wall of the other side of the mounting groove, a guide cylinder is sleeved on the circumferential outer wall of the guide rod, the guide cylinder and the top of the threaded sleeve are both fixedly connected to the movable seat, and a turning handle is fixedly connected to the end of the threaded screw away from the inner wall of the mounting groove.

[0009] As a further solution of the utility model: a slag removal groove is opened on the top outer wall of the workbench, and the slag removal groove is communicated with the installation groove.

[0010] As a further solution of the utility model: a support seat is arranged on the top of the workbench, the support seat is sleeved on the circumferential outer wall of the tube body, and the circumferential outer wall of the support seat is fixedly connected with a fixing frame.

[0011] As a further solution of the utility model: a sticky pad is bonded to the circumferential outer wall of the tube body, and the sticky pad is located below the drill bit.

[0012] As a further solution of the utility model: a scraper is fixedly connected to the outer wall of one side of the support seat, and the bottom of the scraper is tightly attached to the circumferential outer wall of the tube body.

[0013] As a further solution of the utility model: a positioning plate is fixedly connected to the top outer wall of the workbench, a slot is opened on one side outer wall of the positioning plate, a positioning block is fixedly connected to one side outer wall of the fixed frame, and one end of the positioning block is inserted into the inside of the slot.

[0014] As a further solution of the utility model: positioning grooves are provided on both side outer walls of the positioning block, and elastic sheets are fixedly connected to both side inner walls of the slot, and one end of the elastic sheet away from the slot is clamped inside the positioning groove.

[0015] After adopting the above structure, the utility model has the following advantages compared with the prior art:

[0016] 1. In the utility model, by providing a positioning component, when the staff needs to drill a hole in the pipe body, they can first place it on the top of the workbench, and then insert one end of the pipe body into the interior of the positioning seat and turn the handle. In the process of turning the handle, the threaded screw can be driven to rotate, and the threaded sleeve engaged on its outer wall can drive the movable seat to move toward one end of the pipe body through the rotation of the threaded screw, until the movable seat presses the end of the pipe body away from the positioning seat. At this time, the positioning seat and the movable seat can realize the locking work of the pipe body, ensuring that the pipe body will not shake or become unstable during the subsequent drilling process.

[0017] 2. In the utility model, by providing a fixing frame, a support seat and a sticky pad, before the staff fixes one end of the tube body through the movable seat, the support seat can be first sleeved on its outer wall, and then the fixing frame can be pushed to move until the positioning block is inserted into the slot. At this time, the elastic sheet inside the slot will be snapped into the positioning grooves provided on the outer walls on both sides of the positioning block, thereby realizing the locking and fixing of the positioning block, ensuring the stability of the support seat, and the tube body can be effectively supported by the support seat to avoid deformation of the tube body during subsequent drilling.

[0018] 3. In the utility model, by providing a sticky pad and a scraper, the sticky pad can be firstly pasted on the outer wall of the pipe body before drilling a hole in the pipe body. At this time, friction will be generated between the drill bit and the surface of the sticky pad, thereby preventing the drill bit from directly acting on the outer wall of the pipe body and causing slipping. At the same time, after the drilling is completed, when the staff disassembles the support seat and moves it horizontally, the scraper can be used to scrape off the sticky pad adhered to the outer wall of the pipe body, which is convenient for people to use.
