Abstract

PURPOSE: A sand blaster is provided to conveniently process a workpiece and to improve a sanding work efficiency by automatically processing the workpiece employing a sand gun reciprocating around the workpiece on a turntable. CONSTITUTION: A sand blaster comprises a grinding machine(10) for processing a workpiece, a hopper(12) installed below the grinding machine to collect sand and sludge, a turntable(16) rotating by a table motor(18) on the bottom of the grinding machine, and a sand gun(20) reciprocating linearly by a gun moving unit at the upper portion of the turn table. The gun moving unit comprises a gun motor(24) connected with a gear(22), a rack gear(26) moving forward and backward by the rotation of the gun motor, and a pair of supporting shafts(28) connected to the front end of the rack gear. Upon operating the table motor, the gun motor and the sand gun while a workpiece is placed on the turntable, the sand gun automatically processes the workpiece by linearly reciprocating inside the grinding machine. The sand used for grinding the workpiece and the sludge are collected in the hopper. According to automatic machining work, work efficiency is improved. Moreover, the inside of the grinding machine is cleaned easily by the hopper.

Description

샌드블라스트기 { a sandblasting machine }Sandblasting machine {a sandblasting machine}

본 발명은 샌드블라스트기에 관한 것으로, 특히 가공할 공작물을 연마대에 넣고 동작시키면 자동으로 공작물을 가공할 수 있는 샌드블라스트기에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sandblasting machine, and more particularly, to a sandblasting machine capable of automatically processing a workpiece when the workpiece to be processed is put in a grinding table and operated.

일반적으로, 샌드블라스트기는 샌드건을 통해서 나오는 샌드입자로써 공작물의 표면을 가공하는 장치이다. 이러한 샌드블라스트기는 소형공작물일 경우 주로 작업대의 내부에 넣고 작업자가 샌드건을 손으로 잡고 투시창을 통해서 가공하게 된다.In general, a sandblast machine is a device for processing a surface of a workpiece by sand particles coming out through the sand gun. In the case of a small workpiece, the sandblast machine is mainly placed inside a workbench, and the worker holds the sandgun by hand and processes it through the viewing window.

종래 샌드블라스트기는 도 1에 도시된 바와 같이, 연마대(100)에 공작물을 내장시킨 다음, 투입구(102)로 작업자가 샌드건(미도시)을 넣고 투시창(104)을 통하여 공작물을 가공하도록 되어 있다. 상기 연마대(100)는 관통구멍(106a)이 형성된 바닥판(106)이 설치되어 공작물을 가공한 샌드와 슬러지가 상기 관통구멍(106a)을 통하여 호퍼(110)쪽으로 흘러 들어가도록 되어 있다. 그리고, 연마대(100)의 일측에는 개폐도어(108)가 설치되어 공작물을 넣고 빼도록 되어 있다. 한편, 상기 연마대(100)의 하부에는 지지프레임(120)이 설치되어 지면에 흔들리지 않고 지지되게 된다.Conventional sandblasting machine as shown in Figure 1, after inserting the workpiece in the polishing table 100, the operator inserts a sand gun (not shown) into the inlet 102 to process the workpiece through the viewing window 104 have. In the polishing table 100, a bottom plate 106 having a through hole 106a is provided so that sand and sludge having processed a workpiece flow into the hopper 110 through the through hole 106a. On the one side of the polishing table 100, an opening / closing door 108 is provided to insert and remove a workpiece. On the other hand, the support frame 120 is installed in the lower portion of the polishing table 100 is to be supported without shaking on the ground.

그런데, 종래의 샌드블라스트기는 작업자가 직접 샌드건(미도시)을 투입구(102)로 넣어서 공작물을 가공함으로써 작업자가 장시간 작업하는데 한계가 있고, 이에 따라 샌딩작업의 생산능률이 좋지 않았다. 그리고, 종래의 샌드블라스트기는 연마대(100)의 일측면에 소형으로 개폐도어(108)가 설치되어 있으므로 공작물의 부피가 크거나 공작물이 무거울 경우 연마대(100)에 넣고 빼내는데 불편한 단점이 있었다.By the way, the conventional sand blasting machine has a limitation that the operator works for a long time by processing the workpiece by inserting the sand gun (not shown) directly into the inlet 102, and thus the production efficiency of the sanding operation was not good. In addition, the conventional sandblasting machine has a disadvantage in that it is inconvenient to put it in and out of the polishing table 100 when the work piece is large or the workpiece is heavy because the opening and closing door 108 is installed on one side of the polishing table 100 in small size. .

이에 본 발명은 상술한 종래의 샌드블라스트기가 지닌 문제점을 감안한 것으로, 간단한 조작을 통하여 공작물을 자동으로 샌딩작업할 수 있으며, 부피가 큰 공작물이나 무거운 공작물을 연마대에 편리하게 넣고 샌딩작업할 수 있는 샌드블라스트기를 제공하는데 그 목적이 있다.Accordingly, the present invention has been made in view of the above-described problems with the conventional sandblasting machine, and can automatically sand the work through a simple operation, and can conveniently sand the bulky work or heavy work into the polishing table. The purpose is to provide a sandblast group.

상기한 목적을 달성하기 위하여 본 발명은, 샌드건을 통하여 연마대에 내장된 공작물을 가공하고, 공작물을 가공한 샌드와 슬러지가 상기 연마대의 바닥판으로 흘러서 호퍼로 모이도록 구성된 샌드브라스트기에서, 상기 연마대의 바닥판에는 테이블모터에 의해 회전하도록 턴테이블이 설치되고, 상기 턴테이블의 위쪽에 소정의 거리를 두고 샌드건이 건이송수단을 통하여 직선왕복운동하도록 설치된 구조로 되어 있다.In order to achieve the above object, the present invention, in the sandblasting machine configured to process the workpiece embedded in the polishing table through a sand gun, sand and sludge processed the workpiece flows to the bottom plate of the polishing table, and gathered in the hopper, A turntable is installed on the bottom plate of the polishing table so as to be rotated by a table motor, and the sandgun is arranged to linearly reciprocate through the gun transfer means at a predetermined distance above the turntable.

상기 건이송수단은 기어가 축연결된 건모터와, 이 건모터의 기어에 맞물리고 선단에 상기 샌드건이 설치되어 상기 건모터가 회전함에 따라 전후진하는 랙기어 및, 상기 랙기어와 나란하게 배치되고 그 랙기어의 선단부와 연결되어 연동하는 1쌍의 지지샤프트로 구성되어 있다.The gun conveying means is arranged in parallel with the gun motor, the gear is connected to the shaft, the rack gear meshed with the gear of the gun motor and the sand gun is installed at the front end and forward and backward as the gun motor rotates, It consists of a pair of support shafts connected to the leading end of the rack gear.

이와 같은 본 발명에 따른 샌드블라스트기에 의하면, 공작물을 턴테이블 상에 올려놓고 테이블모터와 건모터를 작동시키면, 연마대에 직선왕복하는 샌드건에서 의해서 공작물이 자동으로 가공되게 된다.According to the sandblasting machine according to the present invention, when the workpiece is placed on the turntable and the table motor and the dry motor are operated, the workpiece is automatically processed by the sandgun reciprocating straight to the polishing table.
