Description

Technical Field

[0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a small-size high-precision groove processing device. Background Art

[0002] Computer numerical control machine tools, referred to as NC machine tools, are automated machine tools equipped with a program control system that can logically process programs specified by control codes or other symbolic instructions, decode them, and represent them in coded numbers. They are input into the numerical control device through information carriers, and after calculation and processing, the numerical control device sends various control signals to control the movement of the machine tool, and automatically processes parts according to the shape and size required by the drawing. CNC machine tools have better solved the problem of complex, precise, small batch, and multi-variety parts processing, and are a flexible and high-efficiency automated machine tool.

[0003] When processing grooves on a workpiece, the workpiece is generally clamped directly onto the spindle clamping device of a CNC machine tool, the workpiece is rotated together with the spindle, and then the processing tool is fixed to the tool holder. The tool is controlled to move by the linear movement of the slide, and the tool is allowed to cut the workpiece to achieve groove processing. However, when processing small-sized and high-precision grooves, this processing method is prone to vibration during the processing, because one of the tool and the workpiece rotates and the other is stationary, resulting in reduced processing accuracy of the workpiece. For this reason, a processing device that can avoid vibration and improve processing accuracy is needed. Summary of the invention

[0004] The purpose of the present invention is to propose a small-sized high-precision groove processing device to avoid vibration and improve the groove processing accuracy, in order to solve the problem that during the current groove processing, one of the tool and the workpiece rotates and the other is stationary, which is easy to generate vibration during the processing, resulting in reduced processing accuracy of the workpiece.

[0005] In order to achieve the above-mentioned purpose, the technical solution provided by the present invention is: a small-size high-precision groove processing device, including a slide installed on a CNC machine tool, a fixed plate installed on the slide, a fixture and a driving motor installed on the fixed plate, the output end of the driving motor is connected to a reduction box, the output end of the reduction box is connected to the fixture by transmission, a tool rod is installed on the spindle box of the CNC machine tool, a tool is installed on the tool rod, and the tool contacts the workpiece on the fixture. When in use, the reduction box is driven to rotate by the driving motor, and the fixture is driven to rotate by the reduction box, so that the workpiece and the spindle tool can rotate clockwise at the same time, achieving dual-axis linkage, which can effectively reduce the vibration generated during traditional processing and further improve the processing accuracy of the groove. At the same time, it can reduce the load on the tool during processing, further improve the service life of the tool, and the overall use effect is good.

[0006] Furthermore, the driving motor and the reduction box are connected via a flange coupling.

[0007] Furthermore, pulleys are provided on the output end of the reduction box and the clamp, and a belt is connected between the two pulleys for transmission, so that the rotation of the clamp can be achieved through the belt transmission.

[0008] Furthermore, the belt is a V-belt or a flat belt.

[0009] Furthermore, the slide is installed on the guide rail of the CNC machine tool. The slide has the freedom to move in four directions: front, back, left, and right. The movement of the slide can drive the workpiece to move, thereby realizing the processing of the groove on the workpiece.

[0010] Furthermore, the fixing plate is fixed on the slide table by bolts.

[0011] Furthermore, the fixing plate is provided with a long hole, and the bolt passes through the long hole and is threadedly connected to the slide, and the position of the fixing plate can be adjusted through the provided long hole.

[0012] Furthermore, a quick-release structure is used between the tool rod and the spindle box, and the tool rod can be quickly replaced through the quick-release structure.

[0013] It can be seen from the above technical solutions that the present invention has the following advantages: The reduction gearbox is driven by a driving motor to rotate, and the fixture is driven by the reduction gearbox to rotate, so that the workpiece and the spindle tool can rotate clockwise at the same time, achieving dual-axis linkage. This can effectively reduce the vibration generated during traditional processing and further improve the processing accuracy of the groove. At the same time, it can reduce the load on the tool during processing, further increase the service life of the tool, and have a good overall use effect. BRIEF DESCRIPTION OF THE DRAWINGS
