Description

Technical Field

[0001] This utility model relates to the field of positioning mechanism technology, specifically a positioning mechanism for sawing and milling. Background Technology

[0002] Saw-milling is a composite machining process that combines the characteristics of sawing and milling. It uses high-speed rotation or reciprocating motion of specialized cutting tools such as saw blades and milling cutters to cut, groove, and mill various materials, including metal, wood, and plastic, to obtain precise dimensions, shapes, or complex contours. It combines the efficient cutting capability of sawing with the precision shaping advantages of milling, adapting to diverse needs from simple blanking to complex surface machining. It is widely used in machinery manufacturing, mold making, furniture production, aerospace, and other fields. Some CNC saw-milling equipment can also achieve automated batch processing through program control, further improving machining accuracy and production efficiency.

[0003] In the sawing and milling process, a positioning device is needed to position the workpiece before the milling operation. In existing technologies, the positioning device cannot simultaneously position the workpiece in both the horizontal and vertical directions, resulting in insufficient positioning and negatively impacting the milling and sawing results. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning mechanism for sawing and milling, which solves the problem of not being able to simultaneously position the workpiece in both the horizontal and vertical directions.

A hinge seat is hinged to the outer side of the hinge rod, and a top block is fixedly connected to the outer side of the hinge seat. A support seat is hinged to the inner side of the other end of the hinge seat. The support seat is slidably connected to the worktable and fixedly connected to the slide. By designing this positioning mechanism, the workpiece can be positioned.

[0009] Preferably, the worktable has a through groove inside, and a support seat is slidably connected inside the through groove. By designing the through groove, the support seat can slide inside the worktable.

[0010] Preferably, the adjusting mechanism includes a first bevel gear, which is fixedly connected to the lower end of the motor output. A second bevel gear meshes with the outer side of the first bevel gear. A positive and negative screw is fixedly sleeved inside the second bevel gear. The positive and negative screw is rotatably connected to the fixed seat via bearings. The positive and negative screw is threadedly connected to the slide block. A rotating seat is rotatably sleeved on the outer side of the positive and negative screw via bearings. The rotating seat is fixedly connected to the base plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, through the design of an electric push rod, allows the output end of the electric push rod to push the hinge rod to move. The hinge rod will deflect along the hinge seat, and the hinge seat will deflect along the support seat. At the same time, the hinge rod can deflect along the output end of the electric push rod, thereby realizing the deflection of the pressure block and the top block. The pressure block can press down on the workpiece, and the top block can hold the workpiece tightly, thereby realizing the horizontal and vertical positioning of the workpiece and improving the positioning stability of the workpiece during sawing and milling.

[0014] 2. This utility model utilizes the design of a motor. The output end of the motor can drive the first bevel gear to rotate, which in turn drives the second bevel gear to rotate, thereby realizing the rotation of the forward and reverse screws. This, in turn, enables the threaded movement of the slide block. The slide block can move horizontally along the guide post, thereby adjusting the horizontal position of the pressure block and the top block. This allows for flexible positioning of workpieces of different sizes. Attached Figure Description
