DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0016] like Figure 1-3 As shown, the utility model provides a double-grinding head polishing machine for the inner surface of a head, a grinding head assembly, a grinding head driving motor 1, an adjusting cylinder 2 and a mounting frame 3;

[0017] The grinding head assembly is a grinding part that contacts the inner wall of the head. The grinding head assembly includes a driving wheel 4, a transmission wheel 5 and a sanding belt 6 sleeved on the driving wheel 4 and the transmission wheel 5. The grinding head drive motor 1 is fixedly installed on the mounting frame 3. The driving wheel 4 is fixed to the output end of the grinding head drive motor 1. When the grinding head drive motor 1 is started, the grinding head drive motor 1 drives the driving wheel 4 at its output end to rotate, and the sanding belt 6 sleeved on the driving wheel 4 is driven by the driving wheel 4 to rotate, so as to grind the inner surface of the head.

[0018] In the utility model, the distance between the transmission wheel 5 and the driving wheel 4 can be adjusted by adjusting the extension and contraction of the cylinder 2. Specifically, the transmission wheel 5 is rotatably mounted on the end of the driving shaft 7, and the other end of the driving shaft 7 is fixedly mounted on the output end of the adjusting cylinder 2. The distance between the transmission wheel 5 and the driving wheel 4 can be adjusted to adjust the tension of the sanding belt 6 mounted on the driving wheel 4 and the transmission wheel 5. The outer sides of the transmission wheel 5 and the driving wheel 4 can maintain the grinding shape of the sanding belt 6.

[0019] In the utility model, the base of the adjusting cylinder 2 is fixed on the adjusting plate 8 through a mounting plate, and an angle adjusting cylinder 9 is provided on one side of the adjusting plate 8. The mounting angle of the adjusting cylinder 2 is adjusted by the angle adjusting cylinder 9, and the driving wheel 5 is installed at the end of the adjusting cylinder 2. After the mounting angle of the adjusting cylinder 2 changes, the mounting angle of the sanding belt 6 sleeved on the driving wheel 5 will also change. Specifically, the adjusting plate 8 is rotatably installed with the connecting base 11 through a rotating shaft 10, and a sliding shaft with sliding fit is provided in the arc-shaped adjusting groove 12 on the adjusting plate 8. The sliding shaft is fixedly connected to the end of the angle adjusting cylinder 9, and the angle adjusting cylinder 9 is fixed on the connecting base 11. The mounting angle of the adjusting cylinder 2 is adjusted by telescoping the angle adjusting cylinder 9. When the angle of the adjusting cylinder 2 changes, the length of the adjusting cylinder 2 is also adjusted accordingly, so that the sanding belt 6 is always in an adapted tension.

[0020] In the utility model, the mounting frame 3 is fixed on the body driving frame 13; the mounting frame 3 and the grinding head assembly installed on the mounting frame 3 are driven by the body driving frame 13, thereby driving the grinding head assembly to grind the inner surface of the head workpiece. The specific body driving frame 13 includes a transverse driving mechanism 14 and a longitudinal driving mechanism 15. The mounting frame 3 is moved in the horizontal direction by the transverse driving mechanism 14, and the mounting frame 3 is moved in the height direction by the longitudinal driving mechanism 15. The specific transverse driving mechanism 14 and the longitudinal driving mechanism 15 can adopt a linear motor, a screw mechanism, or a hinge traction mechanism, etc.

[0021] In the utility model, the grinding head assembly, the grinding head driving motor 1 and the adjusting cylinder 2 are respectively provided in two groups and are axially symmetrically arranged. The adjusting cylinder 2 in each group is respectively fixed on the mounting frame 3 through the connecting base 11. The inner surface of the cylinder body is polished by a double grinding head method, and each group of grinding head assemblies can be independently controlled. Using two groups of grinding head assemblies for grinding at the same time can effectively improve the grinding efficiency of the polishing machine.
