Description

Technical Field [0001] The present invention relates to a slide cover for a machine tool,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a slide cover for a machine tool, and more particularly, to a slide cover of a machine tool for reducing cost and improving productivity by greatly simplifying a connection structure with a wiper mounted on a plurality of cover members .

Generally, a machine tool such as a lathe or a grinding machine causes various foreign substances such as chips and cutting oil that are generated in the work of machining work to be piled up on the bottom of the bed, thereby causing contamination and obstructing the operation. A slide cover device is installed.

Such a slide cover is installed on a constant part so that chips generated during cutting of the workpiece can not penetrate into the interior of the machine tool.

In the prior art, a registration cover for a machine tool is disclosed in Registration Utility Model Publication No. 0-0174282.

This will be described with reference to FIG. 1 and FIG.

The slide cover 100 is mounted on the upper portion of the machine tool driving apparatus 200 of FIG. Here, the driving device 200 of a machine tool is a device for moving a work table on which a work to be machined is seated, such as a ball screw or a hydraulic cylinder.

In a machine tool, as a workpiece is processed, a predetermined chip is generated, and the chip thus generated is scattered around the workpiece.

A slide cover (not shown) including a plurality of cover members 111, 112, ... is mounted on the upper portion of the drive unit 200 to prevent chips generated during processing of the work unit from penetrating into the drive unit 200 100 are installed.

The slide cover 100 is configured such that a plurality of cover members 111, 112, ... can be folded or unfolded while sliding inward, and a chip generated in the workpiece during processing penetrates into the drive device 200 And to prevent it from being able to do so.

A chip that is generated when the workpiece is processed and falls to the top of the slide cover 100 is removed by a wiper when the slide cover 100 is contracted or unfolded.

2, wipers 121 and 122 are attached to the front ends of the cover members 111 and 112, respectively, which constitute the slide cover 100. As shown in FIG.

For example, the wiper 121 provided at the front end of the cover member 111 is attached so as to be in close contact with the upper surface of the cover member 112 provided at the lower portion thereof.

Accordingly, when the slide cover 100 is folded, the wiper 121 sweeps the chip, which is separated from the upper surface of the lower surface of the cover member 112, to one side of the slide cover 100.

The wipers 121 and 122 mounted on the front ends of the cover members 111 and 112 have a function of sweeping away the chips that are separated from the upper surface of the slide cover 100. In order to perform the function completely, The wipers 121 and 122 are installed so as to be completely in close contact with the upper surface of the cover member provided below the wipers 121 and 122.

The cover members 111 and 112 are formed with bent portions 111a and 112a at the ends of the cover members 111 and 112. The upper ends of the wipers 121 and 122 are provided with seating grooves 121a and 122a, A welding hole 121c is formed.

The assembling process of the slide cover 100 using the cover member and the wiper thus configured will be described.

First, an adhesive is applied to the upper seating grooves 121a and 122a of the wipers 121 and 122, and then the metal plates 121b and 122b are inserted and fixed.

Then the wipers 121 and 122 are joined to the cover members 111 and 112 and then the metal plates 121a and 121b and the cover members 111 and 112 are welded 121d to each other by spot welding through the welding holes 121c, The slide cover 100 is assembled.

Therefore, this technique solves the problem that the wipers are damaged by the high-temperature chip by preventing the wipers 121 and 122 from being exposed by forming the bending portions 111a and 112a at the tip end portions of the cover members 111 and 112. [

This technique is also applicable to a case where a conventional slide cover is manufactured by using a plurality of fastening bolts when fastening a wiper to a cover member and by making the relative time of the fastener produced by exposing the head of the fastening member to the surface of the cover member And the problem of aesthetics and noise are solved.

However, this technique is also applied to the case where the metal plates 121b and 122b are inserted into the seating grooves 121a and 122a of the wipers 121 and 122 by using an adhesive when the wipers 121 and 122 are mounted on the cover members 111 and 112, And a plurality of spot welds are required to be performed through the holes 121c and 122c for welding the metal plates 121b and 122b and the cover members 111 and 112. Thus, This problem still occurs.

Registration Utility Model No. 20-0174282, Registration Utility Model No. 20-0237551, Publication No. 10-2014-0064201, Publication No. 10-2015-0050258

[

Therefore, when the upper surface concave-convex parts 141a and 142a of the wipers 141 and 142 are engaged with the bottom surface concave-convex parts 131b and 132b of the protective covers 131 and 132, they are fixed while being firmly fitted.

According to the present invention, since the bottom surface concave-convex portions 131b and 132b are formed on the inner bottom surface of the cover members 131 and 132 and the bottom surface concave-convex portions 131b and 132b are formed on the upper surfaces of the wipers 141 and 142, , And when the wiper is fixed to the cover member, the concave and the convex portions are coupled and fixed together by interference fit, so that the assembly and manufacture of the slide cover can be greatly simplified.

According to the present invention, when the upper surface concave-convex portions 141a and 142a of the wipers 141 and 142 are engaged with the bottom surface concave-convex portions 131b and 132b of the protective covers 131 and 132, It can also be bonded.

When the adhesive (G) is used, a strong fixing force is obtained.

5 is a cross-sectional view of a main part of a slide cover of a machine tool according to a second embodiment of the present invention.

As shown in the drawings, the slide cover of the machine tool according to the second embodiment of the present invention includes:

A plurality of cover members 131, 132, ..., and a plurality of wipers 141, 142, ..., which are attached to the front ends of the cover members.

The cover members 131, 132, ... are configured to be folded or unfolded in a sliding manner as in the configuration of FIG.

The front end portions of the cover members 131 and 132 are bent portions 131a and 132a formed by bending downward to a predetermined length.

Also, the bottom surface concave-convex portions 131c and 132c are formed on the inner bottom surface of the cover members 131 and 132. The convex portions are configured such that the width of the top portion is gradually widened and the width of the concave portion is gradually widened.

The bottom surface concave-convex portion 131c is formed to have a length corresponding to the length of the wiper to be inserted and mounted.

On the upper surface of the wipers 141 and 142, upper surface concave-convex portions 141b and 142b corresponding to the bottom surface concave-convex portions 131c and 132c of the cover member are formed. The convex portions are configured to widen the width of the top portion, The width of the lower end is gradually widened.

The upper surface concave-convex portions 141b and 142b are formed to have a length corresponding to the length of the cover member to be inserted therein.

When the protective cover and the wiper thus configured are pushed together with the side surfaces of the top surface irregularities 141b and 142b of the wipers 141 and 142 to the side surfaces of the bottom surface irregularities 131c and 132c of the protective covers 131 and 132, I will.

According to the second embodiment of the present invention, the protrusions and depressions of the bottom surface irregularities 131c and 132c of the protective cover and the top surface irregularities 141b and 142b of the wipers 141 and 142, And the recessed portion is structured so as to be widened in width at the lower end so that the protective covers 131 and 132 and the wipers 141 and 142 are combined with each other extremely firmly.
