Abstract
Description
A workpiece drilling device Technical Field
[0001] This utility model relates to the field of machining, and more specifically to a workpiece drilling device. Background Technology
[0002] In the field of machining, drilling is one of the core processes in the manufacturing of sheet metal, composite materials, and precision parts. However, traditional drilling devices generate a large amount of metal chips (iron chips, aluminum chips, etc.) during the friction between the high-speed rotating drill bit and the workpiece. These chips are easily splashed into adjacent processing areas under the action of centrifugal force and airflow, making cleaning difficult and even blocking the next drilling position, thus affecting the drilling accuracy. Therefore, this application proposes a workpiece drilling device to address the above problems. Summary of the Invention

[0019] A workpiece drilling device includes a support frame 101, a drive mechanism connected to the support frame 101, a lifting plate 103 connected to the drive mechanism, two slide rods 301 slidably connected to the lifting plate 103, each slide rod 301 having a baffle plate at its upper end, and a cover 303 fixedly connected to the lower end of each slide rod 301 by bolts, each slide rod 301 having a spring 302 sleeved on it, the spring 302 being located between the lifting plate 103 and the cover 303, and a drill bit 202 rotatably connected to the lifting plate 103, the lowest end of the cover 303 being lower than the lowest end of the drill bit 202.
[0020] A conical surface 305 is provided on the inner wall of the baffle 303, and the conical surface 305 gradually widens from top to bottom.
[0021] The upper end of the lifting plate 103 is fixedly connected to the drive motor 201 by bolts, and the drill bit 202 is fixedly connected to the output shaft of the drive motor 201.
[0022] The upper end of the drill bit 202 is fixedly connected to a rotating plate 203 by a key, and the lower end of the rotating plate 203 is fixedly connected to two scraping brushes 204.
[0023] Both scraper brushes 204 are curved and symmetrically arranged.
[0024] A rubber ring 304 is glued to the lower end of the cover 303.
[0025] A feeding rack 104 is welded to the lower end of the support frame 101.
[0026] The feeding rack 104 is composed of two symmetrically arranged angle steels.
[0027] The drive mechanism includes a cylinder 102, which is fixedly connected to the support frame 101, and a lifting plate 103 is fixedly connected to the moving end of the cylinder 102 by bolts.
[0028] Both 204 scraper brushes are nylon brushes.
[0029] See Figure 3-5.
[0030] When using the drilling equipment, the operator first places the workpiece to be processed, such as a metal plate, on the feeding rack 104. Since the feeding rack 104 is composed of two symmetrically arranged angle steels, the two symmetrically arranged angle steels can limit the movement of the metal plate, thereby ensuring that the metal plate can move in a straight line.
[0031] When it is necessary to drill holes in a metal plate, the operator manually pushes the metal plate within the feeding rack 104, or uses a linear moving device to push the metal plate within the feeding rack 104. Then, the drive motor 201 drives the drill bit 202 to rotate. At the same time, the moving end of the control cylinder 102 extends, thereby driving the lifting plate 103 to move downward. The lifting plate 103 drives the drill bit 202 to move downward. When the drill bit 202 rotates and contacts the metal plate, it can drill holes in the metal plate.
[0032] See Figures 3 and 5.
[0033] Since the lowest point of the baffle 303 is lower than the lowest point of the drill bit 202, when the drill bit 202 moves downward, the baffle 303 first comes into contact with the surface of the metal plate. When the drill bit 202 continues to move downward to drill a hole in the metal plate, the baffle 303 stops moving, and the two slide rods 301 slide upward on the lifting plate 103. At the same time, the two springs 302 are compressed by force. At this time, the baffle 303 plays the role of blocking the debris.
[0034] When the drill bit 202 drills a hole in the metal plate, the baffle 303 can block the discharged debris and concentrate the discharged debris inside the baffle 303, preventing the debris from flying around and falling on the next drilling position, thereby preventing it from affecting the drilling accuracy and improving the convenience of subsequent cleaning.
[0035] The rubber ring 304 serves to protect the metal plate and prevents the cover 303 from directly contacting the surface of the metal plate, thus avoiding indentation.
[0036] Because the inner wall of the baffle 303 is provided with a conical surface 305, which gradually widens from top to bottom, it is easier for debris to accumulate near the inner wall of the baffle 303 when it flies out, thus reducing the impact of debris rebounding after contacting the inner wall of the baffle 303 on the drill bit 202.
[0037] When the drill bit 202 rotates, it drives the rotating plate 203 to rotate, and the rotating plate 203 drives the two scraper brushes 204 to rotate. After the drill bit 202 drills a hole in the metal plate, the drill bit 202 continues to rotate, and the two scraper brushes 204 rotate to clean the debris around the drilling position of the drill bit 202. Since the two scraper brushes 204 are both arc-shaped and symmetrically arranged, they can throw the debris around, so that the debris can accumulate near the inner wall of the baffle 303.
