Description

Quick change device for drill bit of common boring machine

Technical Field

The utility model belongs to the technical field of the drill bit clamping, specifically speaking relates to a quick change device of ordinary boring machine drill bit.

Background

When the ordinary boring machine needs to drill holes with different specifications, the replacement of the drill bit is troublesome and labor-consuming, and the safety is low. The existing drill bit clamping device of the common boring machine is characterized in that a drill bit is placed in a Morse taper shank hole and fixed by using a flat tail of the drill bit, so that the drill bit does not rotate along with a main shaft, a special tool is required to smash the drill bit during replacement, the replacement is very troublesome, the labor intensity is very high, and certain dangerous factors exist.

SUMMERY OF THE UTILITY MODEL

Aiming at various defects in the prior art, the inventor researches and designs a quick change device of a drill bit of a common boring machine in long-term practice.

In order to achieve the above object, the utility model provides a following technical scheme:

a quick-change device for a drill bit of a common boring machine comprises a sleeve, a quick-change drill bit chuck arranged on one side in the sleeve, and a taper shank clamping shaft arranged on the other side in the sleeve.

Furthermore, a cavity is arranged in the sleeve, and the taper shank clamping shaft is arranged in the cavity and is in interference fit with the sleeve.

Furthermore, a square hole is formed in one end, close to the drill bit quick-change chuck, of the cavity, and the tail of the drill bit quick-change chuck is installed in the square hole.

Further, the taper shank clamping shaft comprises a taper part and a shaft part, and a mounting part is arranged between the taper part and the shaft part.

Furthermore, two mounting grooves are symmetrically formed in the mounting piece.

Furthermore, a first mounting hole is formed in the sleeve.

Furthermore, a second mounting hole is formed in the shaft part of the taper shank clamping shaft.

Further, the first mounting hole and the second mounting hole are fastened through a pin or a bolt.

The utility model has the advantages that:

the taper shank clamping shaft and the drill bit quick-change chuck are arranged in the sleeve, and only the drill bit quick-change chuck needs to be taken down and the drill bit clamped by the quick-change chuck needs to be replaced, so that the drill bit is more convenient and labor-saving to replace, and the taper shank quick-change chuck is simple in structure and more wide in application.

Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the following description is given with reference to the accompanying drawings of the present invention for clear and complete description of the technical solution of the present invention. Based on the embodiments in the present application, other similar embodiments obtained by persons of ordinary skill in the art without any creative effort shall fall within the protection scope of the present application. In addition, directional terms such as "upper", "lower", "left", "right", and the like in the following embodiments are directions with reference to the drawings only, and thus, the directional terms are used for the purpose of illustration and not for the purpose of limiting the present invention. Furthermore, the terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

The present invention will be further described with reference to the accompanying drawings and preferred embodiments.

Referring to fig. 1 to 4, the utility model discloses a quick change device of a drill bit of a common boring machine, including sleeve 1, install drill bit quick change chuck 3 of one side in sleeve 1 and install taper shank clamping shaft 6 of opposite side in sleeve 1.

A cavity 2 is arranged in the sleeve 1, and the taper shank clamping shaft 6 is arranged in the cavity 2 and is in interference fit with the sleeve 1. The square hole 5 is formed in one end, close to the drill bit quick-change chuck 3, of the cavity 2, the tail portion of the drill bit quick-change chuck 3 is of a square structure, and therefore the tail portion of the drill bit quick-change chuck 3 is installed in the square hole 5 in the sleeve 1. The drill bit quick-change chuck 3 is fixed in the sleeve 1 and does not move relative to the sleeve 1, and the tail part of the drill bit quick-change chuck 3 is of a universal structure, so that various types of drill bit quick-change chucks 3 can be installed on the sleeve 1.

The taper shank clamping shaft 6 comprises a taper part 7 and a shaft part 8, a mounting part 9 is arranged between the taper part 7 and the shaft part 8, and the mounting part 9 is used for being connected with a common boring machine and matched with an inner hole of the common boring machine, so that the taper part 7 of the taper shank clamping shaft 6 is fixed on the common boring machine.
