Technical Field
[0001] The utility model belongs to the technical field of metal precision part manufacturing equipment, and particularly relates to a drilling device for manufacturing metal precision parts. Background Art
[0002] A drill press mainly refers to a machine tool for machining holes in workpieces with a drill bit. Usually, the rotation of the drill bit is the main movement, and the axial movement of the drill bit is the feed movement. In order to machine some inclined holes that intersect each other, or at any angle, or at a certain angle with the center line of the machined part, vertical holes or parallel holes, etc. on certain parts, various special deep hole drill presses have been developed and manufactured in various countries.
[0003] Since there is a certain distance between the drill bit of the drill press and the workpiece, and there is a certain inclination angle when observing from the upper side with the eyes, it is very difficult to quickly and effectively aim at the drilling position, resulting in the problem that it is more troublesome to aim at the drilling position of a conventional precision drill press.
[0004] Therefore, we propose a drilling device for manufacturing metal precision parts to solve the above problems. Content of the Utility Model
[0005] The purpose of the utility model is to solve the problem that it is more troublesome to aim at the drilling position of a conventional precision drill press, and to propose a drilling device for manufacturing metal precision parts.
[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0007] A drilling device for manufacturing metal precision parts includes a precision drill press body. A bracket is fixedly connected to the lower end of the precision drill press body, and a support table is fixedly connected to the lower part of the precision drill press body. A lifting frame is arranged on the support table, and the rear part of the lifting frame slidably penetrates through the support table. A aiming ring is fixedly connected to the lifting frame. Pull the lifting frame upward with one hand to make the lifting frame rise along the support table. Drive the aiming ring to rise through the lifting frame. Place a plate-shaped workpiece between the support table and the lifting frame with the other hand, and then release the lifting frame to make the lifting frame rest on the plate-shaped workpiece. Observe the plate-shaped workpiece through the aiming ring and operate the plate-shaped workpiece until the drilling position is aligned with the inner opening of the aiming ring, which is convenient for aiming at the drilling position of the plate-shaped workpiece.
[0008] Preferably, a bolt is threadedly installed at the lower part of the lifting frame. Pull the lifting frame upward to make the lifting frame slide upward along the support table. When pulling the lifting frame upward excessively, use the bolt to block under the support table to prevent the lifting frame from detaching from the support table conveniently.
[0009] Preferably, the support table includes a table body and a connecting block. A sliding opening and an avoidance opening are hollowed out at the upper end of the table body. The lifting frame is conveniently slidably connected through the sliding opening, and the drill bit of the precision drill press body is conveniently avoided through the avoidance opening.
[0010] Preferably, the lifting frame includes a pull button, a sliding column, a restraint ring and a fixing block. A threaded hole is provided in the lower part of the sliding column, and a clamping groove is provided at the upper end of the restraint ring. The lower end of the pull button is fixedly connected to the upper end of the sliding column, and the rear end of the restraint ring is fixedly connected to the sliding column. Pull the pull button upward, so that the pull button acts upward on the sliding column, and the sliding column rises along the support platform. Using the support platform to restrain the lifting frame can conveniently and stably restrain the lifting path of the restraint ring.
[0011] Preferably, finger grooves are provided at the upper end of the restraint ring. Squeeze the aiming ring through the finger grooves, take out the aiming ring, and then put another aiming ring with a different caliber into it, which is convenient for replacing aiming rings with different calibers.
[0012] Preferably, an elastic piece is fixedly connected to the fixing block, and the lower end of the elastic piece is in movable contact with the restraint ring. Using the elastic piece to press on the aiming ring can prevent the aiming ring from detaching from the lifting frame and improve the stability of the aiming ring.
[0013] Preferably, the aiming ring includes a clamping ring, a rotation limiting block and an insertion block. Aiming openings and aiming grooves are hollowed out on the clamping ring. The clamping ring is fixedly connected to the rotation limiting block, and the insertion block is fixedly connected to the lower end of the clamping ring. After inserting the insertion block into the restraint ring, use the clamping ring to be stuck in the clamping groove, so that the aiming ring is kept in the restraint ring, and use the insertion block to limit the rotation of the aiming ring to improve the direction stability of the aiming groove.
[0014] In summary, the technical effects and advantages of the present utility model are as follows:

[0016] 2. Pull the lifting frame upward, so that the lifting frame slides upward along the support platform. When pulling the lifting frame upward excessively, use the bolt to block under the support platform, which is convenient for preventing the lifting frame from detaching from the support platform.
[0017] 3. Pull the pull button upward, so that the pull button acts upward on the sliding column, and the sliding column rises along the support platform. Using the support platform to restrain the lifting frame can conveniently and stably restrain the lifting path of the restraint ring.
[0018] 4. Squeeze the aiming ring through the finger grooves, take out the aiming ring, and then put another aiming ring with a different caliber into it, which is convenient for replacing aiming rings with different calibers.
[0019] 5. After inserting the insertion block into the restraint ring, use the clamping ring to engage in the card slot, so that the aiming ring is held in the restraint ring. Use the insertion block to restrict the rotation of the aiming ring and improve the directional stability of the aiming slot. BRIEF DESCRIPTION OF THE DRAWINGS
