specific Embodiment approach

[0025] As an improved specific embodiment, the drilling device 2 includes a drill bit 21, a second drive mechanism, a coupling 27 and a drill bit clamp 22, the drill bit 21 is fixed with the drill bit clamp 22, and the second drive mechanism The drill bit holder 22 is driven to rotate, and the second driving mechanism includes a drilling motor and a cone wheel assembly, the drilling motor is fixed on the frame 1, and the cone wheel assembly includes a driving cone wheel 23, a driven cone wheel 24 and a cone wheel assembly. Belt 25, described driving cone wheel 23 and driven cone wheel 24 are rotatably installed on the frame 1, and described driving cone wheel 23 is coaxially fixedly connected with the rotating shaft of drilling motor, and described driving cone wheel 23 and slave The driving cone wheel 24 is connected through a belt 25 , and a drive shaft 26 is coaxially fixed on the driven cone wheel 24 , and the drive shaft 26 is connected to the drill clamp 22 through a coup...

Embodiment approach

[0027] As an improved specific embodiment, the push assembly includes a fastening plate 39 and a fastening bolt 36, the fastening plate 39 is fixed on the fastening cover 32, and a threaded hole is opened on the fastening plate 39, The fastening bolt 36 is threadedly connected with the threaded hole, and one end of it is against the clamping block 34 to push the clamping block 34 to move. The fastening bolt 36 rotates in the threaded hole, and the top column clamps the block 34, and pushes the clamping block 34 to move, the connection is firm, and the operation is convenient.

[0028] As an improved embodiment, the clamping block 34 is provided with a positioning hole 40 for inserting the fastening bolt 36 . The fastening bolt 36 is inserted in the positioning hole 40 to prevent the clamping block 34 from loosening the drill bit 21, and the clamping block 34 rotates so that the clamping block 34 is separated from the fastening bolt 36 to ensure that the fastening bolt 36 can p...

Abstract

The invention discloses a bench drilling machine. The bench drilling machine is characterized by comprising a rack, a drilling device and a clamp. The drilling device and the clamp are arranged on the rack. The clamp comprises a clamping device used for clamping a to-be-machined part, and a driving device driving the clamping device to move. The driving device comprises an installation table, a driving seat and a first driving mechanism used for driving the driving seat to move. The clamping device is arranged on the driving seat. The installation table is fixed to the rack. The driving seat is slidably arranged on the installation table. The first driving mechanism comprises a driving motor and a screw rod. The driving motor is fixed to the installation table. The screw rod is coaxially fixed to a rotary shaft of the driving motor. The driving seat is provided with a first threaded hole. The screw rod penetrates through the first threaded hole and is in threaded connection with the first threaded hole. The bench drilling machine can machine a kidney-shaped hole and other special-shaped holes. The screw rod is used for driving the driving seat to move, the structure is simple, and moving is precise and controllable.

Description

technical field [0001] The present invention relates to a drilling tool, more specifically relates to a bench type drilling machine. Background technique [0002] A drilling machine mainly refers to a machine tool that uses a drill bit to process holes in a workpiece. Generally, the rotation of the drill bit is the main movement, and the axial movement of the drill bit is the feed movement. Most of the existing drilling machines fix the workpiece on the frame or fixture, the workpiece cannot be moved during drilling, and structures such as waist-shaped holes cannot be processed, which limits the scope of use of the drilling machine. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a bench type drilling machine, which enables the workpiece to move during processing. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a desktop drill...
