Description

Surface grinding machine swing fine-tuning structure

This creation provides the technical field of a surface grinder, especially a surface grinder's swing fine-tuning structure. The shaft sleeve is mainly sleeved on the swing adjusting rod so that it can be in surface contact in the long groove of the swing cam Slippage can achieve precise and stable control and prolong service life.

Press, refer to the first to third figures, which are three-dimensional exploded, three-dimensional and plane sectional views of the conventional swing structure. The surface grinding machine can refer to the fourth to seventh and twelfth figures. It includes a machine with a lower transmission wheel device installed under the machine, and a push air cylinder installed above the machine. An upper tension wheel device is fixed at the top of the actuating rod of the cylinder. The actuating rod can not only move up and down, but also has a degree of freedom of swing. The side between the upper tension wheel device and the top of the machine is equipped with a conventional swing structure. A conventional swing adjustment lever 11 is provided. The upper section of the conventional swing adjustment lever 11 is provided for manual fine adjustment of the hand-screw screw to correct and adjust the swing angle of the upper tension wheel device. The lower section of the conventional swing adjustment lever 11 is provided for a conventional swing cam 12 The elongated groove 121 is framed for automatically controlled push or pull by the pneumatic cylinder, and automatically fine-tunes the swing angle of the upper tension wheel device accordingly.

However, the long groove 121 of the conventional swing adjusting lever 11 and the conventional swing cam 12 only have two lines of contact with each other, the first line 111 and the second line 112, so the conventional swing adjusting lever is frictionless due to long-time work. 11 and the long groove 121 of the conventional swing cam 12 are easy to wear. On the other hand, the contact between the first line 111 and the second line 112 also makes the control accuracy and stability relatively poor. There is a need for improvement.

Therefore, how to develop an innovative structure with more ideal and practicality in response to the problems of the above-mentioned conventional structure is what consumers are eagerly awaiting, and it is also the goal and direction for the relevant industry to strive for research and breakthrough.

In view of this, the creator has many years of experience in manufacturing, development and design of related products, and after detailed design and careful evaluation for the above goals, he finally has a practical creation.

The main purpose of this creation is to provide a surface grinder swing fine-tuning structure, which is mainly sleeved on the swing adjusting rod, so that it can slide in the long groove of the swing cam in a surface contact manner to ensure surface contact slip. Those who achieve precise and stable control and prolong service life.

In order to achieve the above-mentioned purpose, this creation provides a fine-tuning structure for the swing of a surface grinder, which includes: a lower transmission wheel device under the machine table, a push air cylinder group connected to an upper tension wheel device above the machine table, and the upper tension wheel The device and the lower transmission wheel device are covered with abrasive cloth for grinding, and the pneumatic cylinder is pushed so that the upper tension wheel device can rise and fall, and can swing freely; mainly for the machine and the upper tension One side between the wheel devices must be equipped with a swing fine-tuning structure, including a manual fine-tuning structure and an automatic swing fine-tuning structure. The automatic swing fine-tuning structure is driven by a pneumatic cylinder to pivotally connect to the swing cam of the machine, and one end of the swing adjusting rod is limited. To one side of the upper tension wheel device, a shaft sleeve is sleeved on the other end. The shaft sleeve is provided with parallel first and second planes. The swing cam has a long groove and the first and second groove planes are in surface contact with the first and second planes. According to this, when the swing adjusting rod and the upper tension wheel device are swung, the sleeve must be slipped in the long groove to ensure that the slippage that can be surface contact reaches its control accuracy and stability and prolongs the service life.

Regarding the techniques, methods and effects used in this creation, I will cite a preferred embodiment and detailed descriptions in conjunction with the drawings. I believe that the above-mentioned purpose, structure and features of this creation should be understood in depth and concretely. .
