Description

Repeatedly usable's tight head of polishing that expands

Technical Field

The utility model belongs to the technical field of the head of polishing, in particular to repeatedly usable expands and tightly polishes head.

Background

At the automatic in-process of polishing, the abrasive paper of polishing is the consumptive material, needs frequent change, and the overhead winding of current polishing is polished abrasive paper, when needing to be changed abrasive paper, takes off abrasive paper more difficult, consuming time.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a repeatedly usable expands and tightly polishes head to solve above-mentioned problem.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a reusable expansion polishing head comprises a cutter handle fixing flange, an abrasive paper positioning disc, an expansion mechanism and a sand paper tube; the fixed center that sets up in abrasive paper positioning disk one side of handle of a knife mounting flange, abrasive paper positioning disk another side are provided with the abrasive paper section of thick bamboo, and tight mechanism that expands sets up in the abrasive paper section of thick bamboo, can make the grow of abrasive paper section of thick bamboo diameter.

Furthermore, the expansion mechanism comprises an expansion screw, a screw rod and an expansion device; handle of a knife mounting flange is hollow structure, and the inflation screw setting is in handle of a knife mounting flange, and the coaxial setting of lead screw is inside an abrasive paper section of thick bamboo, the top and the inflation screw fixed connection of lead screw, and an abrasive paper section of thick bamboo is inside to be the toper bucket structure, and the tight device threaded connection cover that expands is established on the lead screw.

Furthermore, the sand paper tube is a plastic tube, the expansion device is of a disc-shaped structure, and the diameter of the expansion device is the same as the maximum diameter inside the sand paper tube.

Furthermore, cylindrical abrasive paper is sleeved on the outer side of the abrasive paper cylinder.

Compared with the prior art, the utility model discloses there is following technological effect:

the utility model discloses a tight cutter of polishing expands, including tight mechanism, fixture and cylindrical abrasive paper bucket expand, fixture provides cylindrical handle of a knife, can supply any lathe and equipment to snatch fast, and the flange face is from taking the clamping position location, guarantees the position precision of repetitious usage cutter. The cylindrical profiling mechanism of the expansion mechanism is made of plastic, and good elasticity avoids damage to a cutter or a workpiece caused by hard touch in the polishing process. The conical expansion device is pulled by the linkage of the expansion screw on the rotating mechanism handle and the internal screw rod, and the expansion device moves upwards to push the outer surface to extrude outwards through the conical surface in the extrusion profiling plastic mechanism and form expansion force with the inward force of the inner surface of the cylindrical abrasive paper. And locking the cylindrical abrasive paper barrel. After the outer surface of the cylindrical abrasive paper barrel loses the polishing effect, the screw is expanded in a reverse rotating mode, the expansion device moves downwards, the plastic profiling mechanism returns to the original shape, the interaction between the cylindrical abrasive paper barrel and the plastic profiling device disappears, and the expansion force disappears. The spent sandpaper can be easily removed.

Drawings

FIG. 1 is an overall schematic view of the present invention;

FIG. 2 is a front view of the present invention;

fig. 3 is a cross-sectional view of the present invention.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

referring to fig. 1 to 3, a reusable expansion polishing head includes a holder fixing flange 1, a sand paper positioning plate 3, an expansion mechanism and a sand paper tube 7; the fixed center that sets up in 3 one sides of abrasive paper positioning disk of handle of a

knife mounting flange

1, 3 another sides of abrasive paper positioning disk are provided with abrasive paper section of thick bamboo 7, and tight mechanism that expands sets up in abrasive paper section of thick bamboo 7, can make 7 diameter grow of abrasive paper section of thick bamboo.

The expansion mechanism comprises an expansion screw 4, a screw rod 5 and an expansion device 6; handle of a knife mounting flange 1 is hollow structure, and inflation screw 4 sets up in handle of a knife mounting flange 1, and 5 coaxial settings of lead screw are inside a sand paper section of thick bamboo 7, and the top and the inflation screw 4 fixed connection of lead screw 5, the inside toper bucket structure that is of a sand paper section of thick bamboo 7, and 6 threaded connection covers of tight device that expand are established on lead screw 5.

The sand paper tube 7 is a plastic tube, the expansion device 6 is of a disc-shaped structure, and the diameter of the expansion device 6 is the same as the maximum diameter inside the sand paper tube 7.

The outer side of the sand paper tube 7 is sleeved with cylindrical sand paper.

As shown in fig. 1 to 3, the present embodiment provides a cylindrical sandpaper expanding sanding head. The self-made cylindrical sand paper 2 required by grinding is sleeved on the sand paper cylinder 7, and the upper section of the cylindrical sand paper 2 is abutted against the sand paper positioning surface 3. The expansion screw 4 is screwed up to link the screw rod 5 to rotationally pull the expansion device 6 to move upwards, the expansion device 6 extrudes the sand paper tube 7 through the conical surface of the sand paper tube 7, and the outer surface of the profiling piece is stressed to expand outwards to be tightly attached to the inner surface of the cylindrical sand paper 2 to form expansion force. The expanding cylindrical sand paper 2 is used for polishing. When the outer surface of the round sand paper 2 fails, the expansion screw 4 is reversely loosened to drive the screw rod 5 to rotate to push the expansion device 6 to move downwards, the expansion device 6 loosens the sand paper tube 7 through the conical surface of the sand paper tube 7, the outer surface of the profiling part is stressed to contract inwards to return, the expansion force of the inner surface of the cylindrical sand paper 2 disappears, and the cylindrical sand paper 2 is easily taken down. And replaced with new sandpaper.
