Abstract

The utility model discloses an acetylene cutting circular component device used for cutting flame, comprising a base, a bearing, a magnet, a core clamper, a rotary body, a screw, a transverse rod, a socket sleeve, etc. The magnet and the bearing are arranged in the step hole of the base, and the rotary body is arranged in the holes of the bearing and the magnet. The rotary body is provided with an axial hole, and a spring and the core clamper are arranged in the hole. The transverse rod is arranged on the upper part of the rotary body, and the socket sleeve of the end part of the rotary body is provided with the acetylene cutter. While in operating, the acetylene cutter is fixed on the blank of the steel plate depending on the utility model and positioned through the core clamper, and work is steady. The positioning is reliable, rotation is flexible and portable, and the acetylene cutter only needs one person to operate.

Description

Acetylene cutting device for circular spare-part

The utility model relates to a kind of flame-cutting plant, is particularly useful for acetylene incising circular part.

At present, with acetylene incising circular part, use the device that is made of top cross bar and acetylene cutter, dependence is top in the work locatees on the steel plate blank; A cross bar is adorned on top top, and crossbar end is installed acetylene cutter; Need two people's compounding practices, one of them people is gripping top in order to avoid the centre of location moves, and another people holds acetylene cutter around the top circular motion of doing, and control acetylene flame cuts the distance of steel plate blank; In the work progress, two workmans' mutual alignment needs repeatedly conversion; And the thickness of acetylene flame depends on the distance of acetylene cutter and steel plate blank surface; This distance relies on workman's experience hand-guided now, and the workman needs high concentration energy in the operation, and tired easily, labour intensity is big; In addition, when the steel plate blank was in vertical plane or operator's end face, the operator was difficult to cooperate, and the element precision that cuts out is not high.

The purpose of this utility model is the device with acetylene incising circular part that magnet and rolling bearing are housed in a kind of base that designs in order to overcome above-mentioned deficiency, only needs people's operation just can cut out the circular pieces of degree of precision.

The utility model content, the base of acetylene incising circular component device makes to have stepped hole, and upper hole is installed bearing, and bottom hole is installed magnet, stretches out in the top hole by the base bottom; Rotary body is a step axle, and the hole of its underpart and bearing and magnet matches, and the rotary body center does that the axial hole that top and spring are installed is arranged, and top does that the hole that cross bar is installed is arranged, and the cross section of cross bar is polygon and makes to have the size groove on one face.

The cross bar of acetylene incising circular component device for pentagon such as wait that hexagon also can be or etc. quadrangle.

The utility model advantage at first, is equipped with magnet in the base of acetylene incising circular component device, utilizes the suction of magnet that this device is attracted securely on the steel plate blank, does not need the people to help, and saves artificial.Secondly, doing on the cross bar has the size groove, only needs during cutting to adjust the position of acetylene cutter on cross bar according to the radius of part, has removed the workman from and loaded down with trivial details operation such as has measured, checks with chi repeatedly.The 3rd cross bar can design and adjustment according to theory is calculated and practical experience draws the acetylene flame optimum distance to the steel plate blank to the size of base bottom surface, has both guaranteed product quality, has also alleviated working strength of workers.

Description of drawings:

Fig. 1 is the utility model schematic diagram.

Fig. 2 loads onto acetylene cutter work schematic diagram for the utility model.

Below in conjunction with description of drawings the utility model embodiment, acetylene incising circular component device is made up of base (1), bearing (2), magnet (3), top (4), rotary body (10), screw (11), cross bar (9) and cover for seat major parts such as (12); At base (1) stepped hole of having got on the bus, upper hole is installed bearing (2), and bottom hole is installed magnet (3), and top (4) are by stretching out in base (1) base apertures; Rotary body (10) is a step axle, and the hole of its underpart axle and bearing (2) and magnet (3) matches, and the rotary body center does that the axial hole that top (4) and spring (5) are installed is arranged, and the hole of installation cross bar (9) is done to have in top; The cross section of cross bar (9) is to wait hexagon, and makes to have the size groove on a side; After packing bearing (2) into, base (1) top makes axial limiting with elastic collar; When being loaded on, bearing (2) limits its axial location with elastic collar (6) after rotary body (10) is gone up.During work, generally on the steel plate blank, give and dash conelet hole, top (4) of the present utility model are put into; Because the suction of magnet is inhaled base (1) on the steel plate blank securely, compresses spring (5) simultaneously, top (4) are positioned in the awl hole on the steel plate blank reliably; Cover for seat (12) is equipped with in the end of cross bar (9), and acetylene cutter (13) wherein is installed; The workman hands the axis rotation of acetylene cutter (13) around top (4), can cut out the circular pieces of degree of precision; Owing between base (1) and rotary body (10), bearing (2) is housed, so light flexibly when operating.When a next cutting member of part cutting finishing transfer, only need crowbar (or screw driver) is inserted between the face (7) and steel plate blank of base, can separate the utility model with the steel plate blank.

Claims

1, a kind of top acetylene incising circular component device of cross bar, cover for seat and centering that comprises is characterized in that base (1) car has stepped hole, and upper hole is installed bearing (2), and bottom hole is installed magnet (3); Top (4) are by stretching out in base (1) base apertures; Rotary body (10) is a step axle, and the hole of its underpart and bearing (2) and magnet (3) matches, and rotary body (10) center does that the axial hole that top (4) and spring (5) are installed is arranged, and the hole of installation cross bar (9) is done to have in top; The cross section of cross bar (9) is polygon and does that in a side size groove is arranged.

2, by the described acetylene incising circular of claim 1 component device, the section that it is characterized in that cross bar (9) is for waiting hexagon, also can be etc. pentagon or etc. quadrangle.
