Description

Technical Field

[0001] The utility model relates to the technical field of metal part processing, in particular to a drilling machine for metal part processing. Background Technique

[0002] In some applications, especially in the fields of aerospace and automobiles, it is crucial to reduce the weight of parts. As a commonly used fastener, the weight of bolts will also affect the overall structure. By drilling holes in the bolt rod, the weight of the bolt can be effectively reduced on the premise of ensuring strength and function, so as to achieve lightweight design. Generally, a drilling machine is used to drill holes in the bolt rod.

[0003] Currently, when drilling holes in the bolt rod, generally the whole bolt is embedded in a mold with a groove, and then the drilling operation is carried out. Due to the vibration generated during drilling, the bolt will shift, resulting in unsatisfactory hole position and vertical accuracy. It is necessary to flip the bolt and drill the same hole position again to complete the whole drilling process of the bolt.

[0004] Since the whole bolt fits in the groove, after drilling on one side is completed, it is necessary to take out the bolt, flip it and put it back into the groove for subsequent drilling operations until the drilling is completed, and then take out the bolt from the groove. This process requires repeated demolding of the bolt, which is rather cumbersome and not convenient enough. Content of the Utility Model

[0005] The purpose of the utility model is to provide a drilling machine for metal part processing, so as to solve the problem that since the whole bolt fits in the groove, after drilling on one side is completed, it is necessary to take out the bolt, flip it and put it back into the groove for subsequent drilling operations until the drilling is completed, and then take out the bolt from the groove. This process requires repeated demolding of the bolt, which is rather cumbersome and not convenient enough as put forward in the above background technique.

[0027] The driving mechanism includes a chute 504, a third rod body 505, a fourth rod body 506, a second micro motor 507, and a side plate 508;

[0028] Chutes 504 are respectively opened inside the two second rod bodies 503. A third rod body 505 is slidably connected inside the two chutes 504 together. A fourth rod body 506 is connected to the third rod body 505. A side plate 508 is connected to the side wall of the third plate body 5. A second micro motor 507 is installed on the side plate 508.

[0029] A support plate 4 is slidably connected to the top end of the base plate 1. A slot hole is opened inside the support plate 4. A driving member for driving the support plate 4 to move horizontally is provided on the base plate 1.

[0030] The driving member includes a second plate body 401 and a screw rod 402;

[0031] A second plate body 401 is connected to the top end of the base plate 1. A screw rod 402 is rotatably connected inside the second plate body 401.

[0033] The drilling module 102 includes a U-shaped plate, an electric push rod, a motor, and a drilling rod;

[0034] At the top of the frame 101 is connected a U-shaped plate, at the top of the U-shaped plate is connected an electric push rod, at the output end of the electric push rod is installed a motor, and the output end of the motor is sleeved with a drilling rod; the electric push rod drives the motor and the drilling rod to move reciprocally, and the motor can drive the drilling rod to rotate, so as to drill the bolt workpiece 2.

[0035] Working principle: First, insert the bolt workpiece 2 into the inside of the support plate 4 until the rod part of the bolt workpiece 2 enters the first plate body 3 and the three-jaw chuck 301. By rotating the screw rod 402, the support plate 4 slides on the slide rod 403, so that the predetermined hole position of the rod part of the bolt workpiece 2 is directly below the drilling module 102, thus playing an adjusting role for bolt workpieces 2 of any length. The positioned bolt workpiece 2 is clamped and fixed by the three-jaw chuck 301. The bolt workpiece 2 is drilled by the drilling module 102. The first micro-motor 305 drives the gear 303 connected to the first rod body 304 to rotate, so that the gear 303 drives the three-jaw chuck 301 connected to the gear ring 302 to rotate 180° on the first plate body 3, turning the bolt workpiece 2 over. Then, the drilling module 102 drills the hole of the bolt workpiece 2 again until after the drilling is completed, the second micro-motor 507 can be made to drive the fourth rod body 506 to rotate, so that the fourth rod body 506 drives the third rod body 505 to rotate inside the chute 504, thus making one end of the second rod body 503 rotate on the base plate 1, and the other end of the second rod body 503 drives the connecting block 502 to drive the push rod 501 to move reciprocally inside the third plate body 5, thereby pushing the bolt workpiece 2 after drilling out of the inside of the three-jaw chuck 301, making the bolt workpiece 2 slide inside the support plate 4 and the first plate body 3, and after tilting, the bolt workpiece 2 finally falls out of the inside of the support plate 4 under the action of gravity, thus playing a discharging role.

[0036] The length of the fourth rod body 506 is less than the radius of the chute 504. When the fourth rod body 506 rotates, it can drive the second rod body 503 to swing. The distance between the two second rod bodies 503 is greater than the overall width of the second micro-motor 507, the side plate 508 and the fourth rod body 506. When the two second rod bodies 503 swing, they will not hit the second micro-motor 507, the side plate 508 and the fourth rod body 506.
