Description

Portable Milling Chamfering Device Capable Of Precise Machining

The present invention relates to a milling beveling device, and more particularly, to a portable milling beveling device capable of precise machining capable of adjusting a position for precise machining of an object to be processed.

In general, chamfering is for chamfering sharp edges of steel, non-ferrous metals, and resins. After processing parts such as metal, it is usually used to remove the dangers caused by burrs and sharp edges on the edge of the product. This is mostly work in stages.

Therefore, the quality of the product depends on the chamfering operation, so it is necessary to increase the surface level as much as possible to obtain a clean slope.

The edge beveler used in the chamfering operation is also called a beveler, and is a tool that processes the edge where the surface and the surface of the member intersect in a bevel or circular shape. It drives and rotates the cutting tip with the driving force to machine the edge of the member.

A burr occurs at the edge of the workpiece during cutting, and refers to the protrusion that occurs as a result of the workpiece being plastically deformed and pushed out as the cutting tool passes the edge of the workpiece.

Since the burr reduces the precision of the workpiece and affects the safety of the operator, it causes a deburring process to remove it, thereby incurring costs and causing a bottleneck of the product. have a large impact on cost.

Since chamfering has to be done by finding all corners of the part, it is difficult to reinstall the workpiece multiple times according to each side in machine tools.

The chamfer used for the chamfering operation can be largely divided into a portable and a fixed type. The portable chamfer is mainly used when the workpiece is heavy and large, and when the workpiece is small and light and can be lifted by an operator, a fixed chamfer is used.

The portable chamfering machine has a straight type and a universal (curved) type, whereas the straight type can process only straight edges, while the universal (curved) type can chamfer not only straight edges but also curved edges, holes, and grooves. In most industrial sites, a portable universal (curved) beveling machine is mainly distributed and used.

In order to control the amount of chamfering during edge chamfering, a general portable chamfering machine adjusts the exposure amount of the rotary cutting tool by releasing the fixed state of the fixture and rotating the screw-coupled guide part according to the user's eyesight.

Therefore, the existing chamfering machine is not only very difficult to control the amount of chamfering, but also takes a lot of work time according to the adjustment of the chamfering amount, thereby reducing work efficiency. The machining member cannot be precisely machined.

In addition, the chamfering amount cannot be precisely adjusted in a certain unit, and the guide part is finely loosened due to vibration caused by strong rotation of the motor during work, resulting in a problem in that the preset chamfering amount cannot be accurately maintained. Moreover, it is very difficult to set the initial reference point of the chamfering amount in the process of reassembling the support holder after separating the guide part and replacing the cutting tip, so there are disadvantages in safety of work and product defects after chamfering.

In the prior art, in order to solve the above problems, a cutting tool housing in which a rotary cutting tool is rotatably installed and a fixed spline is formed on the upper outer surface, and the cutting tool housing is screwed to the upper portion of the cutting tool housing and provides rotational force to the rotary cutting tool An adapter selectively connected to a tool to be connected to the tool, a scale fitted between an outward flange formed on the outside of the adapter and a cutting tool housing, and a rotary spline on the outer surface of the cutting tool housing that are screwed so as to be traversed up and down. The formed transfer guide holder and the support holder screwed to the lower portion of the transfer guide holder and formed with a guide plate at the bottom, the rotary spline of the transfer guide holder, and the fixed spline of the cutting tool housing and the rotary spline formed on the inner surface are coupled and optionally the upper, Chamfering with easy adjustment of the chamfering amount, characterized in that it consists of a chamfering amount adjusting member for controlling and maintaining the chamfering amount while sliding downward, and an elastic member inserted between the chamfering amount adjusting member and the support holder to provide an elastic force to the chamfering amount adjusting member instrument was presented.

The amount of chamfering can be adjusted freely and finely by a simple method of temporarily releasing the lock by sliding the chamfering adjustment tool through the chamfering machine, and then rotating the chamfering amount adjustment tool as much as the divided chamfering scale. , a cutting tool housing including a fixed spline installed for the above operation, and a feed guide holder including a rotary spline, so the structure is quite complicated, and the problem that it is uneconomical because it requires a lot of work time and required personnel have.
