Abstract

The utility model relates to an action roller device which is used for a magnetic profile modeling welding or gas cutting The utility model is characterized in that the roller can expand along axial direction and can be locked when the roller is expanded. The roller is fixed on the rotary magnet of the magnetic profile modeling welding-cutting cutter, when the roller needs to move during the internal and external closed contour on the profile modeling sample plate in the work, and only by pressing the pin tearing outside when the roller is toggled, the recession roller can be locked without elevating the sample plate or dismounting the roller. Therefore, the utility model, which can match with the existing various model magnetic profile modeling welding-cutting cutters, has the advantages of high precision and convenient operation.

Description

Magnetic profile modeling welding-cutting expansion roller

The utility model belongs to the welding mechanical attachment, is specifically related to a kind of scalable roller devices that is used for magnetic profiling welding machinery.

Existing magnetic profiling welding machinery, if used copying template inside and outside contour seals when welding or gas cutting workpiece, when in the work between needing the inside and outside contour of magnetic rollers at model when mobile the general methods such as mounting or dismounting roller or lifting model that adopt realize that there are shortcomings such as copying accuracy is low, operation inconvenience in these methods.

The utility model proposes a kind of roller can axial stretching, and the roller devices that can lock when retraction, and being processed with L shaped groove on band pin roller that wherein can axial stretching and the shell is key point of the present invention.

Concrete structure of the present utility model is illustrated in conjunction with the accompanying drawings.

Fig. 1 has garden, two places post locating surface for roller and shell, and lid adopts threaded engagement with shell, L shaped groove upper end closed on the shell, and pin passes L shaped groove by enclosure and is fixed on structure on the roller.

Fig. 2 is for roller and shell and cover the structure that garden, place post locating surface is respectively arranged.

Fig. 3 adopts elastic pressure to close for the lid and the shell of roller, and pin is by the structure that directly mills out on the roller or be welded on the roller.

Fig. 4 is the garden post locating surface that roller and shell have lengthening, and stage clip is positioned at the structure among the roller endoporus.

Roller among the figure (1), lid (2), pin (3), stage clip (4), shell (5), L type groove (6), garden post mating surface (7), (8), copying template outline (9), profile (11) in the copying template (10), copying template.

Roller and shell are matched in clearance, because the pin that is fixed on the roller stretches out from L type groove, roller only axially can stretched, stirring pin when roller retraction shell just can lock in L type groove, roller can not eject, can be easily move to desired location this moment between the profile of copying template sealing, again with the roller bullet to original position.

Be the assurance copying accuracy during work, roller and shell have certain axiality requirement, therefore adopted the many places locate mode, generally speaking on axially separated by a distance, there is garden, two places post locating surface enough reliably, these two locating surfaces can be positioned on the shell to be guaranteed under the axiality prerequisite as shown in Figure 1 or for easily manufactured, one place is positioned at and covers, and another place is positioned at shell such as Fig. 2.Lid is threaded with general employing of shell, also can adopt elastic pressure shown in Figure 3 to close its middle cover of structure for convenient manufacturing and is stamped to form in the Baltimore groove that is stuck on the shell by sheet metal.The structure of pin and fixed form can be passed L shaped groove and are fixed on the roller with screw thread or interference fit by the roller shown in Figure 1 pin of packing into behind the shell.Can also be by the iron plate of a drawing of usefulness shown in Figure 4, weldering or riveting or be bonded on the roller, this moment, the L type groove upper end on the shell should be opened for ease of assembling, and pin also can be by shown in Figure 3 directly by processing on the roller or being welded on the roller.The another kind of version of making for simplifying, for roller shown in Figure 4 and shell have longer garden post mating surface (L/D＞1), decapacitation at this moment guarantees that outside both axialities, the roller At time of eject also is unlikely because of crooked and blocks.

L shaped groove on the shell and the pin on the roller can be places or arrange two places with respect to 180 ° of directions of axis.

Be to guarantee the transmission of the magnetic line of force, shell and roller all adopt ferromagnetic steel to make, and roller surface also has higher hardness through heat treatment.

Claims

1, a kind of scalable roller devices is made up of roller (1), lid (2), pin (3), stage clip (4), shell (5), L type groove (6) etc.It is characterized in that: roller and shell are matched in clearance, and the pin on the roller passes L shaped groove and stretches out in shell.

2, by the described roller devices of claim 1, it is characterized in that: roller and shell and be stamped garden, many places post locating surface or the garden post locating surface of (L/D＞1) that a place extends is arranged.

3, by the described roller devices of claim 1, it is characterized in that: L shaped groove is arranged on the shell.

4,, it is characterized in that by the described roller devices of claim 2: garden, the many places post locating surface of roller and shell can be all on the shell or one be in and cover all the other on shell.

5, by the described roller devices of claim 1, it is characterized in that: roller and shell all adopt ferromagnetic steel to make.
