Abstract

The present invention relates to a polishing pad to be used in the sanding operation. It is recommended to choose the most suitable pad according to the type of polishing paper (bond type, velcro type), the nature of the polishing work (rough polishing, finish polishing), and the method of collecting dust generated during polishing. . However, since the pads are cumbersome during the operation, the grinder is purchased and used in accordance with various types of pads. In the case of a poor working environment, one type of pad may be used to finish the whole process of polishing. Quality is not implemented correctly

In order to solve this problem, the main pad was devised by comprehensively accommodating various holes of the pad. In addition, the Velcro-treated auxiliary pads are designed to be easily and quickly replaced with pads by sticking them to the main pads. The main pad and the auxiliary pad are collectively called multipurpose pads.

In the case of applying the designed method, it is efficient and economical because it can perform various types of polishing work by the function of the multi-use pad even with one polishing machine.

Description

Multi-purpose pad {Universal Multi Pad}

The polishing pad is located in the middle of the polishing machine and the abrasive paper and is used for cushioning, dust collection, and adhesion of the abrasive paper. Such a polishing pad is divided into a bond type and a Velcro type according to the attachment method of the abrasive paper, and the size and shape are shown in [Table 1]. The shape and number of holes exist in various ways according to the dust collection method of the pad, but [Table 1] is classified based on the number of holes used most.

Size and type of polishing pad Round Bond Pads (Hard / Soft) 125 mm (5 ") 5-hole method 6 holes Etc 5 + 1 holes, 6 + 1 holes 150 mm (6 ") 6 holes Etc 6 + 1 holes Round Velcro Pads (Hard / Soft) 125 mm (5 ") 5-hole method 6 holes Etc 5 + 1 holes, 6 + 1 holes 150 mm (6 ") 6 holes 8 + 1 hole method Etc 6 + 1 holes, 8 + 1 holes Square velcro pad 100 × 180mm European Japanese type Etc

These pads are again divided into hard and soft types due to the nature of the work. Hard type is used for initial and heavy work, while soft type is used for finishing. In the workplace, the pads of the grinder are replaced according to the characteristics of the work, or the grinder is equipped with several grinders according to the type of the pad. In the case of using a single grinder, a pad changing spanner (special tool, see FIG. 4) may be used to replace the pad, or a locking device for pad replacement may be used. This pad replacement work is cumbersome and inconvenient, and when the pad detachable spanner is lost, the pad replacement is not possible and the pads suitable for the polishing work characteristics are frequently not used.

In addition, the abrasive paper attached to the polishing machine is largely divided into a bond type and a Velcro type, and the characteristics of each manufacturer, hole (hole), and waterproof are all varied. Workers can obtain the desired polishing quality by using various characteristics of the abrasive paper, but most of them use only a product using a specific abrasive paper attachment method because the pad replacement method is cumbersome.

The present invention focuses on making it easy to select and use various types of pads.

1. There are many types of pads, depending on the number of holes in the abrasive paper and how the abrasive paper is attached. Accordingly, it should be possible to use various kinds of holes without distinguishing them, and even if the bonding method of the abrasive paper is changed, the pads should be easily replaced without using a separate tool.

2. Due to the nature of the work, the pads should be divided into hard and soft types, but they are not easy to replace. Therefore, the pad replacement work should be easy.

The present invention is a means for achieving the above object,

1. We devised a main pad containing all the various holes according to the pad specification;

2. The design of the hard pads and soft pads suitable for the nature of the work, the bond and velcro pads suitable for the abrasive paper attachment method, and the detachable auxiliary pads regardless of the number of dust collection odds;

Referring to the present invention in detail according to the accompanying drawings as follows.

1.Main Pad (see Figures 1-1, 2 / Figure 2 / Figure 5 / Figure 6)

The shape of the hole of the main pad is shown in FIG. 2 and is configured to include both various types of circular pad holes and various types of various rectangular pad holes. The detachable method of the main pad and the polishing machine is the same as that of the conventional polishing machine (FIG. 4). The upper surface of the main pad (Fig. 1-2) is treated with velcro (Velcro hook processing surface, Figs. 5/6).

2. Auxiliary pads (see Figures 1-3, 4, 5, 6 / Figure 2 / Figure 3 / Figure 6)

The auxiliary pad has a velcro treatment (velcro loop treatment surface, see Figs. 5 and 6) on the bottom surface (Figs. 1-7) so that it can be attached and detached to the top surface (Figs. 1-2) of the main pad. Auxiliary pads are made of different types of materials and thicknesses to adjust their hardness and to include all types of holes. Auxiliary pads (FIG. 6) are made of treated with Velcro abrasive paper and bonded with abrasive paper.

The present invention is described in detail by effect as follows.

<Convenience according to work>

All kinds of polishing pads used for polishing work can be easily and quickly removed.

Efficiency of Polishing Quality Implementation

By applying various auxiliary pads, it is easy to obtain the polished surface to be implemented.

Utilization of Grinding Machine

The inconvenience of having to replace various types of pads in order to obtain the polished surface to be implemented when using a conventional grinding machine eliminates the waste of purchasing and using several polishing machines.
