[0021] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0022] like Figure 1-4 As shown, the embodiment of the utility model provides a double-head force-controlled grinder for grinding and polishing, including a driving box 10, a plurality of motor mounting seats 9 are fixedly connected to the bottom end of the driving box 10, and the plurality of motor mounting seats 9 are evenly distributed, a column 2 is fixedly connected to the upper end of the driving box 10, a force controller 8 is fixedly connected to the column 2, two grinding contact wheels 1 are connected to the force controller 8, a motor 12 is fixedly arranged on the bottom surface of the inner cavity of the driving box 10, a synchronous gear 13 is fixedly sleeved on the output shaft of the motor 12, the synchronous gear 13 is connected to a driving wheel 14 through a synchronous belt 15, and the driving wheel 14 is rotatably connected to the column 2, the driving wheel 14 transmits power to the grinding contact wheel 1 through a sanding belt 16, a sanding belt tensioning wheel assembly 4 is fixedly installed in the middle part of the column 2, and the The sanding belt tensioning wheel assembly 4 abuts against the sanding belt 16, and the sanding belt tensioning wheel assembly 4 is used to achieve the tensioning and relaxing of the sanding belt 16. The upper end of the column 2 is fixedly connected with a correction assembly 7, and the correction assembly 7 abuts against the sanding belt 16, and the correction assembly 7 is used to stabilize the sanding belt 16 in the middle position of the grinding contact wheel 1; it also includes an electrical controller 5 and a transmission wheel 6, the electrical controller 5 is fixedly connected to the column 2, and the electrical controller 5 is electrically connected to the sanding belt tensioning wheel assembly 4 and the motor 12, the electrical controller 5 is used to control the operation of the sanding belt tensioning wheel assembly 4, and the electrical controller 5 is also used to control the rotation, speed regulation and stop of the motor 12, as well as the automatic and manual switching functions.

[0023] In the embodiment of the utility model, the tensioning and loosening of the sanding belt 16 is achieved through the sanding belt tensioning wheel assembly 4, so that the tension can be adjusted when the sanding belt 16 is replaced, and the sanding belt 16 can be stabilized in the middle position of the grinding contact wheel 1 through the correction assembly 7. The motor 12 provides power for the driving wheel 14, and the transmission direction of 16 is changed by 6, which has the effect of working in coordination, improving efficiency and reducing costs.
