Description

Technical Field

[0001] The utility model relates to the technical field of drilling machines, in particular to a drilling positioning device for drilling machines. Background Art

[0002] A drilling machine refers to a machine tool that mainly uses a drill bit to process holes on a workpiece. The main motion is usually the rotation of the drill bit, and the axial movement of the drill bit is the feed motion. During the processing, the workpiece does not move, and the tool moves to align the center of the tool with the center of the hole, and the tool rotates.

[0003] However, the size of the clamping block in the existing device is fixed. Although it can clamp and position workpieces of different lengths, it cannot clamp and position workpieces of different widths. The processing range of the drilling machine will still be affected. As an auxiliary device of the drilling machine, it obviously does not meet the use requirements.

[0004] For example, a drilling positioning device for a drilling machine disclosed in announcement number CN221435726U has the advantage of adjustable clamping area through the cooperation of a table, a clamping frame, an adjusting plate, a first screw, a through port, a support bar, a connecting frame, a threaded sleeve, a second screw, a motor, a support frame, a fixing frame, a dust collection shell, a placement frame, a dust collection box, a dust filter, a dust collection pipe, a mounting frame and a fan, which solves the problem that the size of the clamping block of the existing drilling positioning device of a drilling machine is fixed. Although it can clamp and position workpieces of different lengths, it cannot clamp and position workpieces of different widths. The processing range of the drilling machine will still be affected. As an auxiliary device of a drilling machine, it obviously cannot meet the use requirements.

[0005] However, during use, the device rotates the first screw so that one end of the first screw drives the adjustment plate to move and clamp one side of the workpiece, resulting in low clamping efficiency, which affects the drilling efficiency of the workpiece.

[0006] For this reason we urgently need to provide a kind of drilling positioning device that drilling machine uses. Utility Model Content

[0012] Preferably, there are two connecting plates, and the lower ends of the two connecting plates are rotatably connected to the inside of the bracket, and the upper ends of the two connecting plates are rotatably connected to the bottom of the left and right clamps respectively. By starting the telescopic part to pull the bracket downward, the connecting plate is driven to pull the left and right clamps to move toward each other, clamping workpieces of different specifications in the middle of the workbench, thereby realizing the positioning and clamping of the workpiece.

[0013] Preferably, a limiting groove is provided on the upper surface of the workbench, and the width of the limiting groove is equal to the width of the connecting plate, so that the limiting groove prevents the connecting plate from being blocked by the workbench when rotating around the bracket and the splint.
