In order to improve the polishing effect and efficiency, a power mechanism can be added to the existing polishing head mechanism to drive the polishing head to rotate, so that the polishing head and the grinding disc rotate in opposite directions. However, the polishing head equipped with a power mechanism will occupy a large space, which is not conducive to the design and processing of a multi-head polishing machine, and it is necessary to ensure the position stability of the polishing head during operation.

[0003] Therefore, designing a blasting head device that occupies less space and has greater stability is a problem that needs to be solved by those skilled in the art. Summary of the Invention

By designing a new type of polishing head device, the whole is in a vertical shape, which reduces the space occupied by the polishing head mechanism, facilitates the design and production of double-head or multi-head polishing machines, thereby improving the use efficiency and polishing effect of the polishing machine. At the same time, the designed polishing head device has a rotation function and a telescopic function, while improving the operating stability and improving the use effect of the polishing head device.

The piston end of the lifting cylinder passes through the top of the outer sheath and is fixed to the top of the lifting column.

[0010] The lifting column is fixed with a rotating sleeve through a bearing, the workpiece tooling plate is fixed to the bottom end of the rotating sleeve, and the top end of the rotating sleeve is fixed with a driven gear, which is sleeved on the outside of the lifting column and does not interfere with the lifting column;

[0011] A connecting horizontal edge is fixed to the bottom end of the lifting column, and the connecting horizontal edge is located above the driven gear and does not interfere with the driven gear. The driving motor is fixed to the top of the connecting horizontal edge away from the end of the lifting column, and the output end of the driving motor is fixed with a driving gear that meshes with the driven gear.

[0012] Furthermore, a guide groove is provided on the peripheral side surface of the lifting column along the length direction, and a guide edge is provided in the outer guide sleeve to slide in cooperation with the guide groove.

[0013] Furthermore, a limiting cover is fixed to the peripheral side surface of the bottom end of the lifting column, and the upper surface of the connecting horizontal edge is in contact with the bottom surface of the limiting cover.

[0017] The utility model has the following beneficial effects:

[0018] 1. The utility model designs a new type of blasting head device, which is in a vertical shape as a whole, reducing the space occupied by the blasting head mechanism, facilitating the design and production of double-blasting head or multi-blasting head polishing machines, thereby improving the use efficiency and polishing effect of the polishing machine. At the same time, the designed blasting head device has rotation and telescopic functions, while improving the operating stability and improving the use effect of the blasting head device.

[0019] 2. The utility model adopts the outer guide sleeve and the lifting column as the active guide for lifting through the design of the outer sleeve, the outer guide sleeve and the lifting column.
