Description

Technical Field

[0001] This utility model relates to the field of drilling machine positioning technology, specifically to a positioning device for a drilling machine. Background Technology

[0002] A drilling machine is a machine tool used for machining holes. Depending on its structure and purpose, it can be classified as a bench drill, a vertical drill, a radial drill, etc. In addition, special types of drilling machines can be designed and modified according to the processing requirements of the product.

[0003] Application number 202121761609.2 provides a positioning device for a bench drill. Through the cooperation between the worktable, the first screw, the handle and the clamping plate, the object to be drilled can be clamped and fixed. Through the cooperation between the frame, the second screw and the pressure plate, the thin plate placed on the object to be drilled can be pressed and fixed. Through the cooperation between the drill body and the moving components, the worktable can be adjusted in a conventional position and drilled. The dust removal mechanism can suck in the debris generated during drilling to achieve the dust removal effect. This device eliminates the traditional method of manually holding and fixing the thin plate, and uses a special instrument to fix its position.

[0004] When adjusting the position of the clamping plate, the above-mentioned drilling machine positioning device requires turning the handle to control the movement of the clamping plate; however, since the handle is turned manually, it lacks the locking button for locking the position adjustment found in existing drilling machines, which makes the handle easy to be touched and turned, or cause it to rotate when clamping the workpiece, making it inconvenient to operate.

[0005] Therefore, a positioning device for drilling machines has become an urgent problem for the entire society to solve. Utility Model Content

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a positioning device for a drilling machine, including a lifting drill, a support base provided at the bottom end of the lifting drill, and a workpiece positioning adjustment device provided below the drill bit of the lifting drill. The workpiece positioning adjustment device includes a workpiece transverse adjustment device and a workpiece longitudinal adjustment device. The workpiece transverse adjustment device includes a transverse drive motor, a transverse moving base, a transverse rotating lead screw, and a transverse sliding block. The transverse rotating lead screw is connected to the output end of the transverse drive motor, the transverse sliding block is connected to the transverse rotating lead screw, the transverse moving base is installed below the transverse rotating lead screw, and the workpiece longitudinal adjustment device is installed on the transverse sliding block.

[0007] The workpiece longitudinal adjustment device includes a longitudinal drive motor, a longitudinal adjustment base, a longitudinal adjustment screw, a longitudinal sliding block, and a mounting plate. The output end of the longitudinal drive motor is used to connect with the longitudinal adjustment screw. The longitudinal sliding block is connected to the longitudinal adjustment screw. The longitudinal adjustment base is located above the longitudinal adjustment screw. The top end of the mounting plate is used to connect the longitudinal sliding block, and the bottom end is used to connect the transverse sliding block.

[0012] The advantages of the utility model compared to the prior art are:

[0013] This invention adds a workpiece lateral adjustment device and a workpiece longitudinal adjustment device to the support base. The workpiece lateral adjustment device includes a lateral drive motor, a lateral moving base, a lateral rotating lead screw, and a lateral sliding block. The lateral drive motor drives the lateral rotating lead screw to rotate, thereby causing the lateral sliding block on the lateral rotating lead screw to drive the workpiece longitudinal adjustment device to adjust its lateral position. This structure allows for arbitrary adjustment of the workpiece's lateral position without manual intervention. The longitudinal workpiece longitudinal adjustment device includes a longitudinal drive motor, a longitudinal adjustment base, a longitudinal adjustment lead screw, a longitudinal sliding block, and a mounting plate.
