Description

Technical Field

[0001] The utility model relates to the technical field of machine tools, in particular to an adjustable machine tool pressing plate. Background Art

[0002] Lathes are machine tools that mainly use turning tools to turn rotating workpieces. Drills, reamer, reamers, taps, dies and knurling tools can also be used on lathes for corresponding processing. Lathes are mainly used to process shafts, discs, sleeves and other workpieces with rotating surfaces. They are the most widely used type of machine tools in machinery manufacturing and repair factories.

[0003] When the machine tool is processing, most of them will use a pressure plate to position the placed workpiece, and the pressure plate is usually driven up and down by a hydraulic cylinder. However, the hydraulic cylinder cannot adjust the descent range of the pressure plate according to the thickness of the workpiece. As a result, when processing thicker workpieces, the workpiece and the pressure plate will be subjected to huge pressure from the hydraulic cylinder, resulting in damage, affecting the processing of the workpiece. Utility Model Content

[0004] The purpose of the utility model is to provide an adjustable machine tool pressure plate to solve the problem proposed in the above-mentioned background technology that the hydraulic cylinder in the machine tool cannot adjust the lowering range of the pressure plate according to the thickness of the workpiece, resulting in that when processing thicker workpieces, the workpiece and the pressure plate will be subjected to huge pressure from the hydraulic cylinder, resulting in damage, thereby affecting the processing of the workpiece.

[0008] By adopting the above technical solution, when in use, after the workpiece is placed in the specified position, the trigger plate on the side of the pressing plate body is driven to move downward by the downward movement of the pressing plate body. When moving downward, the trigger plate contacts the trigger switch on the top of the electric push rod, thereby triggering the trigger switch, controlling the motor to stop working, and stopping the further downward movement of the pressing plate body, thereby conveniently avoiding damage to the workpiece or the pressing plate body when the pressing plate body continues to move downward, and the pointing plate installed on the side of the trigger switch points to the scale line on the side of the gantry, which is convenient for controlling the height of the trigger switch, thereby controlling the descent amplitude of the pressing plate body.

[0009] As a further solution of the utility model: a front-to-rear conveyor belt is installed at the middle position of the top of the machine, and a control panel is installed on the side wall of the machine.

[0010] By adopting the above technical solution, when in use, the workpiece is driven to move back and forth to a specified position by the conveyor belt, and the control panel facilitates the mutual coordination of the components in the control device.

[0011] As a further solution of the utility model: a vertical guide rod is installed in the lifting slot away from the trigger plate, and the guide rod passes through the pressure plate body.

[0012] By adopting the above technical solution, when in use, the guide rod has a guiding effect on the lifting and lowering of the pressure plate body.
