Description

Waterproof and dustproof knife handle

Technical Field

The utility model relates to a machining equipment technical field specifically is a waterproof dust-protection type handle of a knife.

Background

The phenomenon that one end face of a spring chuck is exposed exists in spring chuck knife handles of various models of ER systems used in current market places, and cutting cooling liquid or cutting debris particles fly into a slotting gap of the spring chuck when a knife tool works normally. The spring chuck can rust due to long time for cutting coolant to enter the inner hole of the spring chuck. Cutting debris particles enter the spring chuck, a clearance groove at the exposed end of the spring chuck can be blocked, the cutter bar and an inner hole of the spring chuck are quickly abraded, the service life of the spring chuck is shortened, and the large T.I.R (radial runout error) of the cutter bar can be caused, so that the machining size precision is influenced.

Disclosure of Invention

An object of the utility model is to provide a waterproof dust-protection type handle of a knife to solve the problem that proposes among the above-mentioned background art.

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

a waterproof and dustproof type knife handle comprises a knife handle main body, wherein an A through hole for installing a knife rod is formed in the knife handle main body, the knife handle main body is used for connecting a machine tool main shaft and the knife rod, a spring chuck for clamping and fastening the knife rod is accommodated in the A through hole, a knife rod installing cap is further sleeved on the knife handle main body, and the installing cap is sleeved on the outer side of the spring chuck; and a sealing ring is arranged at the position of the abutting surface of the mounting cap and the cutter bar.

As a further aspect of the present invention: the sealing ring is an O-shaped ring.

As a further aspect of the present invention: the sealing ring is arranged in the mounting groove on the mounting cap.

As a further aspect of the present invention: the mounting cap is mounted on the tool handle main body in a threaded connection mode.

As a further aspect of the present invention: the internal thread on the mounting cap is mounted on the external thread on the tool holder main body.

Compared with the prior art, the beneficial effects of the utility model are that: by arranging the sealing ring, cutting cooling liquid and dust are prevented from entering the spring chuck, and the service life of the spring chuck is prolonged; the time for replacing the cutter bar is shortened, and the time for cleaning dust and garbage in the gap of the spring chuck is not needed to be spent each time the cutter bar is replaced; the cutter bar T.I.R (radial runout error) is easy to be ensured to be used in a normal range, and excellent machining dimensional precision is easy to obtain.

Drawings

Fig. 1 is an explosion schematic diagram of a waterproof and dustproof type tool handle.

Fig. 2 is an overall schematic view of the waterproof and dustproof type tool holder.

In the figure: the tool handle comprises a tool handle main body-1, a spring chuck-2, an installation cap-3 and a sealing ring-4.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

Referring to fig. 1-2, in embodiment 1 of the present invention, a waterproof and dustproof knife handle includes a knife handle main body 1, an a through hole for installing a knife bar is provided inside the knife handle main body 1, the knife handle main body 1 is used for connecting a machine tool spindle and the knife bar, a collet chuck 2 for clamping and fastening the knife bar is accommodated in the a through hole, a knife bar installing cap 3 is further sleeved on the knife handle main body 1, and the installing cap 3 is sleeved outside the collet chuck 2; and a sealing ring 4 is arranged at the position of the abutting surface of the mounting cap 3 and the cutter bar and is used for water proofing and dust proofing.

Carry out the centre gripping fastening to the cutter arbor through setting up collet 2, then cooperate the 3 cutter arbor of installing of cap to fix, realized the fast loading and unloading cutter arbor.

Example 2

Referring to fig. 1-2, the main difference between the embodiment 2 and the embodiment 1 is that the sealing ring 4 is an O-ring.

The mounting cap 3 is mounted on the tool holder main body 1 in a threaded connection mode.

The internal thread on the mounting cap 3 is mounted on the external thread on the tool holder main body 1.

The sealing ring 4 is arranged in a mounting groove on the mounting cap 3.

The utility model prevents cutting coolant and dust from entering the spring chuck by arranging the sealing ring 4, thereby prolonging the service life of the spring chuck; the time for replacing the cutter bar is shortened, and the time for cleaning dust and garbage in the gap of the spring chuck is not needed to be spent each time the cutter bar is replaced; the cutter bar T.I.R (radial runout error) is easy to be ensured to be used in a normal range, and excellent machining dimensional precision is easy to obtain.
