Description

Technical Field

[0001] This utility model relates to the field of drilling machines, and more particularly to a novel drilling machine for workpiece machining. Background Technology

[0002] Drilling machines are essential equipment in the drilling process. A drilling machine is a machine tool that primarily uses a drill bit to machine holes in a workpiece. Its main motion is the rotation of the drill bit, with the axial movement of the drill bit serving as the feed motion. Drilling machines have a simple structure and relatively low machining accuracy. They can drill through holes and blind holes. By changing special tools, they can also perform reaming, countersinking, boring, or tapping. During machining, the workpiece remains stationary while the cutting tool moves, aligning its center with the hole center and rotating.

[0003] Common drilling machines, such as radial drilling machines, have a drilling motor that moves horizontally along the radial arm, which rises, falls, and rotates along the column to drill holes at different positions on the top of the workpiece. The drill bit is vertical during drilling, and the hole is a vertical hole. However, when drilling the side wall or other inclined surfaces of the workpiece, the workpiece needs to be flipped over, resulting in low flexibility. Summary of the Invention

[0004] The present invention aims to address the shortcomings of the prior art by providing a novel drilling machine for workpiece machining.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: A novel drilling machine for workpiece processing includes a machine base, with support platforms at both ends of the top of the machine base. An arc-shaped support beam is provided at the top of the support platform, and the support beam is hollow inside. A C-shaped movable seat is mounted on the support beam. A power mechanism for driving the movable seat to move is located inside the support beam. A locking mechanism is provided between the movable seat and the support beam. An inverted U-shaped fixing plate is provided at the bottom of the movable seat. H-shaped guide plates are slidably mounted on the inner walls of both sides of the fixing plate. A drilling motor is located in a groove at the bottom of the guide plate. A drill bit is detachably mounted on the spindle of the drilling motor. An electric push rod is provided at the top of the fixing plate. The piston rod of the electric push rod is fixedly connected to the groove at the top of the guide plate. A workpiece fixing mechanism is provided on the support platform. A rotary table is rotatably mounted on the top of the machine base. A rotary motor for driving the rotary table to rotate is located inside the machine base.

[0006] Specifically, the two support platforms have grooves on their opposite surfaces, and the fixing mechanism includes a fixing electric cylinder set in the groove, with a clamping plate at the end of the piston rod of the fixing electric cylinder.

[0007] Specifically, the power mechanism includes an arc-shaped rack, gear, drive motor, and rotating shaft. The rack is fixed to the lower surface of the cavity inside the support beam. Rollers are provided at the top and bottom of the drive motor. The upper and lower surfaces of the cavity inside the support beam are provided with grooves corresponding to the rollers. The rollers roll within the grooves. The main shaft of the drive motor is fixed to the rotating shaft. The gear is fixed to the rotating shaft and meshes with the rack. The support beam is provided with an arc-shaped sliding hole. The end of the rotating shaft away from the drive motor passes through the sliding hole and is rotatably connected to the moving seat. The rotating shaft slides along the sliding hole.

[0008] Specifically, the top and bottom plates of the movable seat are slidably mounted on the support beam.

[0009] Specifically, the locking mechanism includes a locking electric cylinder and a locking plate. The top plate of the moving seat extends beyond the support beam. The locking electric cylinder is installed at the bottom of the extended end of the top plate of the moving seat. The locking plate is fixed to the bottom of the piston rod of the locking electric cylinder, and the moving seat is locked by pressing the lower surface of the support beam against the locking plate.

[0010] The beneficial effects of this utility model are: by setting a rotary table, it is easy to rotate the workpiece; by setting a fixing mechanism, it is easy to fix the workpiece; by setting an arc-shaped support beam, a moving seat, a power mechanism, a locking mechanism, a fixing plate, a guide plate, a drilling motor, and an electric push rod, it is easy to drill holes in various parts of the outer surface of the workpiece without having to flip the workpiece, making it flexible and convenient to use.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0018] like Figures 1-4 As shown, a novel drilling machine for workpiece processing includes a machine base 1, with support platforms 2 at both ends of the top of the machine base 1. An arc-shaped support beam 3 is located on the top of the support platform 2, and the support beam 3 is hollow inside. A C-shaped movable seat 4 is mounted on the support beam 3. The top and bottom plates of the movable seat 4 are slidably mounted on the support beam 3. A power mechanism for driving the movable seat 4 is located inside the support beam 3. The power mechanism includes an arc-shaped rack 14, a gear 15, a drive motor 16, and a rotating shaft 17. The rack 14 is fixed inside the support beam 3. On the lower surface of the cavity, rollers 18 are provided at the top and bottom of the drive motor 16. The upper and lower surfaces of the cavity inside the support beam 3 are provided with wheel grooves 19 corresponding to the rollers 18. The rollers 18 roll in the wheel grooves 19. The main shaft of the drive motor 16 is fixedly connected to a rotating shaft 17. The gear is fixedly connected to the rotating shaft 17 and meshes with the rack 14. The support beam 3 is provided with an arc-shaped sliding hole 20. The end of the rotating shaft 17 away from the drive motor 16 passes through the sliding hole 20 and is rotatably connected to the movable seat 4. The rotating shaft 17 slides along the sliding hole 20.

[0019] A locking mechanism is provided between the movable seat 4 and the support beam 3. The locking mechanism includes a locking electric cylinder 21 and a locking plate 22. The top plate of the movable seat 4 extends beyond the support beam 3. The locking electric cylinder 21 is installed at the bottom of the extended end of the top plate of the movable seat 4. The locking plate 22 is fixed to the bottom of the piston rod of the locking electric cylinder 21, and the movable seat 4 is locked by pressing the lower surface of the support beam 3 with the locking plate 22.

[0020] The bottom of the movable seat 4 is provided with an inverted U-shaped fixing plate 5. H-shaped guide plates 6 are slidably provided on the inner walls of both sides of the fixing plate 5. A drilling motor 7 is provided in the groove at the bottom of the guide plate 6. A drill bit 8 is detachably installed on the spindle of the drilling motor 7. An electric push rod 9 is provided at the top inside the fixing plate 5. The piston rod of the electric push rod 9 is fixedly connected to the groove at the top of the guide plate 6.

[0021] The support platform 2 is equipped with a workpiece fixing mechanism. The two support platforms 2 have grooves 11 on their opposite surfaces. The fixing mechanism includes a fixing electric cylinder 12 disposed in the groove 11, and a clamping plate 13 is provided at the end of the piston rod of the fixing electric cylinder 12.

[0022] A rotary table 10 is rotatably mounted on the top of the machine base 1, and a rotary motor is installed inside the machine base 1 to drive the rotary table 10 to rotate. By setting up the rotary table 10, it is convenient to rotate the workpiece.

[0023] When this utility model is in operation, the workpiece to be drilled is placed on the rotary table 10, the fixing electric cylinder 12 is started, and the workpiece is clamped and fixed by the clamping plate 12. The drive motor 16 is started, and the gear 17 rotates along the rack 14, thereby driving the moving seat 4 to move along the support beam 3.
