Description

Tool holder dust protection cover

The present invention relates to a tool bar of a processing machine, in particular to a tool bar dust-proof protective cover sleeved on the tool bar.

In order to meet different processing needs, the processing machine usually needs to replace the toolholders and tools of different specifications and types in order to successfully complete the processing operation. Therefore, the toolholders with the tools are usually placed in advance on the side of the processing machine. The desktop or the tool placement table is convenient for the user to replace the tool holder installed on the processing machine when using the processing machine.

Therefore, toolholders with various specifications, types, and lengths that are pre-installed with tools are usually placed on the desktop or tool placement table with the tools facing upwards for users to take. However, due to processing When the machine is processing, the generated chips and dust are easily dispersed in the air. The toolholders placed on the desktop or the toolholder placement table are directly exposed to the processing environment, and the dust and moisture in the processing environment are easily attached to the toolholder. And the surface of the tool, which makes the tool holder and the tool easier to rust, which affects the service life of the tool holder and the tool.

In addition, generally, a plurality of pre-assembled tool holders are placed on the table top or the tool holder placing table at the same time, and these tool holders are placed on the desktop or the tool holder placing table with the knives facing upward, and are equipped with The lengths of the shanks of the knives are different, so when taking the shank placed in the middle, it is easy to be cut by the knives installed on the shanks on both sides.

In view of this, the main purpose of the present invention is to provide a kind of dust protection cover for the tool bar, which can be applied to tool bars of different lengths, and can prevent dust and moisture in the environment from adhering to the tool bar or tool, and can avoid using cut when the user takes the blade.

In order to achieve the above-mentioned purpose, the dustproof protective cover for the cutter bar provided by the present invention includes a plurality of sleeves, and the sleeves can be sleeved from the inside to the outside in sequence relative to the axial sliding, wherein the sleeve with the smallest diameter The tube is defined as an inner sleeve, the top of the inner sleeve has a top cover, the bottom end is an open end, and the inner sleeve of the two adjacent sleeves is provided with a first latching portion adjacent to the bottom end, located at the bottom end. The outer sleeve is provided with a second abutting portion adjacent to the top end, and the first clamping portion of the inner sleeve among the two adjacent sleeves is selectively clamped with the second clamping portion of the outer sleeve. Abutting; wherein the inner peripheral wall of the outer casing adjacent to the bottom end of the adjacent two casings is protruded with a third abutting portion, and the first clamping portion of the inner casing in the adjacent two casings is selective The first abutting portion of each sleeve includes an outer flange protruding radially outward from the outer peripheral wall of the sleeve, and the second abutting portion of each sleeve The latching portion includes a resisting inner flange protruding radially inward from the inner peripheral wall of the sleeve, and each resisting inner flange selectively contacts the top side of the corresponding first latching portion; The second latching portion of the pipe includes a limiting protrusion protruding radially inward from the inner peripheral wall of the sleeve. Below the inner flange, and the radially inwardly protruding distance of the limiting protrusions of each second latching portion is smaller than the radially inwardly protruding distance of the inner retaining flange; The bottom side of the first latching portion selectively abuts against the corresponding limiting protrusions of the second latching portion.

Utilizing the above-mentioned technical features, the cutter bar dust-proof protective sleeve of the present invention includes a plurality of sleeves that can slide relatively axially, and can be applied to the outer periphery of the cutter bars of different lengths to prevent dust or water in the air. The air is in contact with the shank or tool, which improves the direct exposure of the shank or tool to the machining environment It is easy to rust in the middle of the knife, and it can also prevent the user from being cut by the knife installed on the knife rod when the user takes the knife rod.
