Description

Auxiliary mechanism of manual non-contact plasma cutting machine

Technical Field

The utility model relates to a plasma cutting machine field, concretely relates to manual non-contact plasma cutting machine complementary unit.

Background

Plasma cutting is a process in which the heat of a high temperature plasma arc is used to partially or locally melt (and vaporize) the metal at the cut of a workpiece and the molten metal is removed by the momentum of the high speed plasma to form the cut. The manual plasma cutting machine comprises two types of manual non-contact cutting and manual contact cutting.

Manual non-contact cutting is at the cutting in-process, and the nozzle is from controlling between 3~5mm apart from the distance between the work piece plane, and traditional cutting mode all relies on artifical handheld control distance, and this makes and is difficult to look for the reference standard when realizing sharp cutting to make cutting speed slow, cutting effect poor.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art not enough, provide a manual non-contact plasma cutting machine complementary unit, can be used to the supplementary correction of manual non-contact plasma cutting machine cutting process, make its rapid cutting out sharp joint-cutting.

The purpose of the utility model is realized through the following technical scheme:

a manual non-contact plasma cutter assist mechanism, the mechanism comprising:

the fixing ring is provided with at least one screw in the radial direction;

two supporting arms with the same height are symmetrically fixed on two sides of the fixing ring, a roller is mounted at the tail end of each supporting arm, and a spherical convex block is coaxially arranged on the outer side of the roller.

During the use will fix the solid fixed ring cover on manual non-contact plasma cutting machine's nozzle, then pass through the fix with screw to make manual non-contact plasma cutting machine slide on the cutting surface again under the gyro wheel effect, thereby avoid handheld unsettled state, at this moment again be assisted with a straight frame strip, make the sphere lug slide along straight frame strip and cut out mark collimation line seam promptly.

Furthermore, the two supporting arms are parallel to each other or distributed in a splayed shape. Is distributed in a splayed shape and is more stable in the sliding process.

Furthermore, a fixed seat is arranged in the fixed ring at the middle position of the fixed points of the two supporting arms, and a through threaded hole is transversely formed in the fixed seat;

and a screw rod is connected with the threaded hole, the tail end of the screw rod is provided with a stop block, the stop block is provided with a second roller, and the second roller is parallel to the plane where the fixing ring is located and is lower than the bottom of the roller.

The advantage of this scheme design lies in, when the target position standard panel of current cutting, can be tangent with the panel terminal surface through the second gyro wheel, relies on the panel terminal surface to carry out the fly-cutting as the straight line calibration face promptly, can also be according to joint-cutting position adjusting screw length.

Furthermore, the fixing seat is installed on the supporting arm through a fixing part, and the fixing seat is in threaded connection with the fixing part.

Furthermore, the stop block is movably connected with the screw rod through a bearing, so that in the rotating process of the screw rod, the second roller is always parallel to the plane where the fixing ring is located.

Furthermore, the number of the second rollers is two, namely the two rollers are arranged in front of and behind each other, so that the stable motion of the stop block and the end face of the cut plate is ensured.

Furthermore, the support arm is fixed on the side face of the fixing ring through a bolt, and the installation can be more convenient and faster by adopting a bolt mode.

The utility model has the advantages that: the solid fixed ring of this scheme utilization and the composite set of gyro wheel are installed on plasma cutting machine's shower nozzle to make unnecessary unsettled handheld in the cutting process, the accessible gyro wheel slides on the cutting plane, and can guarantee that the interval of nozzle and cutting plane keeps invariable, improve the cutting quality, when the bar panel cutting to standard class, this scheme still designs the structure of an auxiliary dog + second gyro wheel, be linear motion for guarantee the cutting process, thereby improve cutting speed.

Detailed Description

The technical solution of the present invention is described in further detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the following description.

As shown in fig. 1 and 2, an auxiliary mechanism of a manual non-contact plasma cutting machine comprises: a fixing ring 100, at least one screw 500 being radially disposed on the fixing ring 100; two support arms 200 with the same height are symmetrically fixed on two sides of the fixing ring 100, a roller 300 is installed at the tail end of each support arm 200, and a spherical convex block 400 is coaxially arranged on the outer side of each roller 300. The fixing ring 100 can be a circular lantern ring or an anchor ear, the screw 500 can be omitted when the anchor ear is adopted, but the size of the anchor ear can be changed after the anchor ear is adjusted, so that the relative positions of the two support arms 200 are changed, the form of the anchor ear can be customized only, namely, the size is specially customized for a certain type of plasma cutting machine, and the form of the circular lantern ring can be suitable for different types of plasma cutting machines.

In a preferred embodiment, two support arms 200 are parallel to each other or arranged in a splayed manner, and the support arms 200 are fixed to the side surfaces of the fixing ring 100 by bolts. The cutting state of the scheme is as shown in fig. 3, when cutting, a frame strip is used as a reference base surface for sliding the roller 300, so that a straight line is cut, and the spherical convex block 400 is abutted and slid with the reference base surface in the cutting process.

As shown in fig. 4, as a preferred embodiment, in order to omit the use of a peripheral device as a reference base, the present solution is to install a fixing seat 700 at the fixing ring 100 at the middle position of the fixing points of the two support arms 200, the fixing seat 700 is transversely provided with a through threaded hole; a lead screw 800 is connected with the threaded hole, a stop block 900 is installed at the tail end of the lead screw 800, the stop block 900 is provided with a second roller 901, the second roller 901 is parallel to the plane where the fixing ring 100 is located and lower than the bottom fixing seat 700 of the roller 300, the fixing seat 700 is installed on the supporting arm 200 through a fixing part 600, the fixing seat 700 and the fixing part 600 are in threaded connection, the stop block 900 is movably connected with the lead screw 800 through a bearing, and in the rotating process of the lead screw 800, the number of the second rollers 901 is two and is parallel to the plane where the fixing ring 100 is located all.
