Description

Fixing device on bench drill

Technical Field

The utility model relates to a drilling machine technical field especially relates to a fixing device on bench drill.

Background

The drilling machine is a machine tool which mainly uses a drill to machine a hole on a workpiece. Typically the drill bit is rotated into a primary motion and the drill bit is moved axially into a feed motion. The drilling machine is simple in structure, relatively low in machining precision, capable of drilling through holes and blind holes, replacing special cutters, and capable of expanding, reaming or tapping and the like. In the machining process, the workpiece is fixed, the cutter moves, the center of the cutter is aligned with the center of the hole, and the cutter rotates (main motion). The drilling machine is characterized in that a workpiece is fixed, a cutter rotates and feeds along the direction of a main shaft, and the operation can be manual or motor-driven. When an existing drilling machine is used for machining a workpiece, an operator holds the drilling machine for the workpiece to drill the workpiece, but the workpiece deviates.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

As shown in the figure, the utility model discloses a base 1, fix stand 2, the threaded connection on base 1 processing platform 3 on stand 2 and fix drilling subassembly 4 in stand 2 upper end, two relative sliding groove 5 have been seted up on base 1's surface, and 5 internal rotations in sliding groove are connected with first reciprocating screw 6, and threaded connection has connecting block 7 of sliding connection in sliding groove 5 on the first reciprocating screw 6, is fixed with loading board 8 on the connecting block 7, logical groove 13 has been seted up on loading board 8, and last inner wall that leads to groove 13 rotates between with the lower inner wall to be connected with vertical second reciprocating screw 9, and threaded connection has pinch-off blades 10 on the second reciprocating screw 9. Thus, when drilling is needed, a workpiece is firstly placed on the processing table 3, the two first reciprocating lead screws 6 are rotated to enable the clamping plates 10 to be close to the workpiece, and the first reciprocating lead screws 6 are continuously rotated to enable the two clamping plates 10 on the two sides to respectively clamp the two sides of the workpiece so as to fix the workpiece, so that drilling failure caused by movement of the workpiece can be avoided during drilling; when the side surface of the workpiece is irregular, the second reciprocating screw rod 9 can be rotated, and the clamping plates 10 can be moved upwards, so that the clamping plates 10 on the two sides are pressed on the surface of the workpiece to fix the workpiece, and the workpiece can be fixed when encountering irregular workpieces.

Further, an elongated plate 11 is fixed to the front end surface of the clamping plate 10. The contact area with the side surface of the workpiece can be increased by the elongated plate 11, so that the clamping force can be increased to make the fixing effect better.
