Description

Hand-held pneumatic chamfering polisher

Technical Field

The utility model relates to a polisher technical field, in particular to pneumatic chamfer polisher of hand-held type.

Background

When chamfering is performed, it is necessary to perform an operation using a chamfering and grinding machine. When the chamfering polisher is used for chamfering and polishing the plane edge, the handheld chamfering polisher controls the polishing position and the polishing inclination angle, the operation is very inconvenient, and the handheld chamfering polisher is difficult to keep a fixed angle for the polishing cutter head.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to solve above-mentioned problem, provide a pneumatic chamfer polisher of hand-held type, its convenience is controlled the position of polishing, is particularly useful for the edge of same height and polishes, and the angle of polishing is easily controlled.

In order to solve the above problem, the utility model discloses a technical scheme as follows:

the utility model provides a pneumatic chamfer polisher of hand-held type, the inside rotor of its casing passes through the bearing and is connected with the casing, the fixed cover of rotor anterior connection tool bit, the fixed anterior chamfer of connecting of tool bit is polished the tool bit, the chamfer is polished the tool bit and is set up in the casing bottom, a serial communication port, the chamfer is polished the tool bit and is the toper, the outside cover of casing has horizontal positioning disk, rise and tightly overlap, horizontal positioning disk sets up in chamfer and polishes the tool bit top, rise and tightly establish the cover and establish in horizontal positioning disk top, it vertically splits to rise and tightly overlap the lower part, it has the screw thread to rise to overlap the outside, horizontal positioning disk middle part has fixed cover, fixed cover inner wall has the screw thread, the screw thread of fixed cover and.

Further, the tool bit fixing sleeve is connected with the chamfering polishing tool bit through a spline, the tool bit fixing sleeve is provided with magnetism, the chamfering polishing tool bit is provided with magnetism, and the magnetism on the tool bit fixing sleeve and the magnetism on the chamfering polishing tool bit attract each other.

The utility model has the advantages that:

the utility model is suitable for a polish the horizontal plane edge, its horizontal positioning dish is taken to the horizontal plane edge on, and the chamfer edge of polishing is aimed at to the tool bit, and the horizontal positioning dish blocks the horizontal plane edge, impels the chamfer polisher along the horizontal plane edge forward, and the chamfer polisher can be fixed angle to the edge and polish, and the angle of polishing is decided by the toper side gradient of chamfer tool bit of polishing.

When the straight edge lapped by the horizontal positioning disc is narrower and the chamfer grinding tool bit cannot contact the straight edge, the horizontal positioning disc with a small diameter can be replaced.

In order to be suitable for edge polishing at different heights, the horizontal positioning plate can adjust the height, after the tensioning sleeve is fixed on the shell to a good height, the fixed sleeve of the horizontal positioning plate locks the tensioning sleeve, and the tensioning sleeve fixes the horizontal positioning plate on the shell.

Drawings

Fig. 1 is an exploded view of a hand-held pneumatic chamfer sander according to the present invention;

FIG. 2 is an assembly view of a hand-held pneumatic chamfer sander according to the present invention;

description of reference numerals: the device comprises a shell-1, a rotor-2, a tool bit fixing sleeve-3, a chamfer polishing tool bit-4, a horizontal positioning disc-5, a fixing sleeve-51, a tensioning sleeve-6, a bearing-7 and a pneumatic motor-8.

Detailed Description

The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention can be more clearly and clearly defined.

Referring to the attached figure 1 of the specification, a hand-held pneumatic chamfer sander is characterized in that a rotor 2 inside a shell is connected with the shell 1 through a bearing, the front part of the rotor 2 is connected with a tool bit fixing sleeve 3, the rotor is driven by a pneumatic motor 8 and fixedly connected with the tool bit fixing sleeve through screws, the front part of the tool bit fixing sleeve 3 is connected with a chamfer sanding tool bit 4, the chamfer sanding tool bit 4 is arranged at the bottom end of the shell, the bottom surface of the tool bit fixing sleeve 3 is tightly pressed on an inner ring of a bearing 7, an outer ring of the bearing 7 is connected on the end surface of the shell 1, the chamfer sanding tool bit 4 is conical, a horizontal positioning plate 5 and a tensioning sleeve 6 are sleeved outside the shell, the horizontal positioning plate 5 is arranged above the chamfer sanding tool bit 4, the tensioning sleeve 6 is arranged above the horizontal positioning plate 5, the lower part of the tensioning sleeve 6 is, the inner wall of the fixed sleeve 51 is provided with threads, the threads of the fixed sleeve 51 are matched with the threads of the tensioning sleeve 6, the central hole of the fixed sleeve 51 is conical, and the diameter of the lower opening of the fixed sleeve is smaller than that of the upper opening of the fixed sleeve. The tensioning sleeve can move up and down on the shell to adjust the height, and the central hole of the fixing sleeve is conical, so that when the fixing sleeve is screwed from bottom to top, the fixing sleeve is locked by the tensioning sleeve due to the fact that the diameter of the lower opening of the fixing sleeve is small.

However, the chamfering and grinding machine is continuously abraded in the continuous working process, the grinding cutter head needs to be replaced regularly, and the traditional pneumatic chamfering machine is inconvenient to replace the grinding cutter head and complex in operation. The optimization is, the fixed cover of tool bit 3 passes through splined connection with chamfer tool bit 4 of polishing, and the fixed cover of tool bit 3 has magnetism, and chamfer tool bit 4 of polishing has magnetism, and magnetism on the fixed cover of tool bit and the chamfer tool bit of polishing attract mutually, and chamfer tool bit of polishing can be followed the fixed cover of tool bit and directly pulled out, and during the change with chamfer tool bit disembarking of polishing fixed cover of tool bit, the dog drives the chamfer tool bit of polishing rotatory, and magnetic force makes the chamfer tool bit of polishing not break away from the fixed cover of tool bit.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only preferred embodiments of the present invention, and the present invention is not limited by the above preferred embodiments, and various changes and modifications can be made without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the present invention as claimed.
