Description

Technical Field

[0001] The utility model relates to the technical field of machine tool polishing, in particular to an online shaft type rotating polishing device. Background Art

[0002] Polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of a workpiece to obtain a bright and smooth surface. It is a modification process on the workpiece surface using polishing tools and abrasive particles or other polishing media. Polishing cannot improve the dimensional accuracy or geometric shape accuracy of the workpiece, but is intended to obtain a smooth surface or mirror gloss. It is sometimes used to eliminate gloss (matte). Polishing wheels are usually used as polishing tools.

[0003] Machine tool polishing is a polishing device based on CNC machine tools. The polishing device is installed on the machine tool turret to polish shaft workpieces. The installation of the polishing device needs to be kept parallel to the surface of the shaft workpiece. The design diameters of shaft workpieces are different, and there are shapes such as conical surfaces and circular surfaces, which lead to severe unilateral wear of the polishing wheel and affect the polishing quality. For this reason, the polishing equipment is improved to make it easy to install and reliable to adjust, thereby reducing the local wear on one side of the polishing wheel. Utility Model Content

[0004] The purpose of the utility model is to provide a linear axis rotary polishing machine to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The linear axis rotary polishing machine comprises a driving motor, a shell, a mounting seat and a polishing wheel. The driving motor and the polishing wheel are mounted on the shell, and the driving motor and the polishing wheel are driven by a core shaft. The mounting seat has two mounting points with the shell, one of which is rotatably connected to the shell through a movable connecting piece, and the other is rotatably connected to the shell through a push rod and a movable connecting piece. A parallel ruler is mounted on the other side of the shell located on the mounting seat.

[0007] As a further solution of the utility model: the movable connecting member includes a connecting seat and a rotating shaft, the rotating shaft is installed in the connecting seat, and the rotating shaft is rotatably connected to the mounting seat and the push rod through a bearing.

[0008] As a further solution of the utility model: the mounting seat is mounted on the adjusting seat, the adjusting seat is mounted on the rotatable push rod, and the output end of the push rod is rotatably connected to the shell through a movable connecting piece.

[0009] As a further solution of the utility model: a tool holder assembly hole is provided on the mounting seat.

[0010] As a further solution of the utility model: the outer side of the core shaft is connected to the housing through a tapered roller bearing, and the housing is equipped with a bearing gland for fixing the tapered roller bearing.

[0011] As a further solution of the utility model: the core shaft fixes the polishing wheel through a locking piece, and the core shaft and the parallel ruler are parallel to each other.

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

[0013] The online axis rotary polishing machine completes the initial installation and correction by assembling the workpiece with a parallel ruler. The mounting seat, shell and push rod form a triangular structure. The angle between the mounting seat and the shell is changed by the extension and retraction of the push rod, so as to change the polishing angle of the polishing wheel. When the inclined surface, conical surface and other surfaces of the workpiece that are not parallel to the central axis of the workpiece are processed, the polishing wheel will not be subject to local or unilateral wear, which will affect the subsequent polishing effect.

[0018] See also Figures 1 to 3In the embodiment of the utility model, the linear axis rotary polishing machine includes a driving motor 1, a housing 2, a mounting seat 4 and a polishing wheel 7. The housing 2 is provided with the driving motor 1 and the polishing wheel 7. The driving motor 1 and the polishing wheel 7 are driven by a mandrel. The mounting seat 4 has two mounting points with the housing 2, one of which is rotatably connected by a movable connecting piece 3, and the other is rotatably connected by a push rod 6 and the movable connecting piece 3. The housing 2 is located on the other side of the mounting seat 4 and a parallel ruler 11 is installed. The mounting seat 4 is provided with a tool holder assembly hole 8. The mounting seat 4 is used to fix the polishing machine on the tool holder of the machine tool through the tool holder assembly hole 8 and bolts. During installation, the shaft workpiece is first installed on the machine tool fixture. Calibrate the coaxiality of shaft workpieces. When installing the polishing machine, the parallel ruler 11 is close to the plane of the workpiece to make the workpiece, parallel ruler 11 and core shaft parallel to each other, complete the position correction of the polishing machine, and fix the position of the polishing machine with bolts. The push rod 6 is a high-precision electric push rod. The extension and retraction of the push rod 6 controls the inclination angle of the housing 2 to complete high-precision position calibration and automatic adjustment of the polishing of inclined surfaces such as conical surfaces. The extension and retraction of the push rod 6 can be controlled by the control system of the CNC machine tool to achieve online adjustment. The distance between the polishing wheel 7 and the workpiece after the tool holder coordinate compensation is adjusted can improve the polishing accuracy, make the polishing surface of the polishing wheel 7 highly fit with the workpiece, and avoid unilateral wear affecting the polishing efficiency and polishing quality.

[0019] In a preferred embodiment, the movable connecting member 3 includes a connecting seat and a rotating shaft. The rotating shaft is installed in the connecting seat, and the rotating shaft is rotatably connected to the mounting seat 4 and the push rod 6 through a bearing. The movable connecting member 3 serves as an adjustable connecting structure. While meeting the rotatable conditions, when the stroke of the push rod 6 is fixed, it can play a stabilizing role, keep the structure of the equipment from deformation, and meet the angle changes.

[0020] In a preferred embodiment, the mounting seat 4 is installed with the adjustment seat 5, and the adjustment seat 5 is installed with a rotatable push rod 6. The output end of the push rod 6 is rotatably connected to the shell 2 through a movable connecting piece 3. The mounting seat 4, the shell 2 and the push rod 6 form a triangular structure. When the length of the mounting seat 4 and the shell 2 remains unchanged, the push rod 6 adjusts the angle between the mounting seat 4 and the shell 2 by telescoping, thereby changing the polishing angle. Therefore, all inner angles of the triangular structure formed by the mounting seat 4, the shell 2 and the push rod 6 need to be rotatably connected.

[0021] In a preferred embodiment, the outer side of the core shaft is connected to the housing 2 through a tapered roller bearing. The housing 2 is equipped with a bearing cover 9 for fixing the tapered roller bearing. The core shaft fixes the polishing wheel 7 through a locking plate 10. The core shaft and the parallel ruler 11 are parallel to each other, which can minimize the initial error during installation.
