Description

The hose package that is used for welding equipment
Technical field
The present invention relates to the described hose package equipment of a kind of aforementioned part according to claim 1, described hose package equipment has the hose package that is used for welding equipment.
Background technology
The hose package that introductory song is described type is to use as the transmission equipment between the actuating element of welding equipment; transmission equipment between just so-called gas nozzle and the bonding machine body, bonding machine body are used to generate welding current and storage and are connected welding medium (for example sealing wire and protective gas).The top priority of the hose package of using as transmission equipment is under the situation that does not influence the gas nozzle operation, to guarantee that electric current and medium are transported to bonding machine.Its situation about especially being suitable for is, if relate to the hose package that is used to be installed on the welding robot, hose package is arranged in and is installed in the gas nozzle on the robot joint and is installed between the circuit guide device in the fixing robot base zone, on the one hand, hose package must not hinder the superimposed motion of robots arm's limb and the compound movement that forms, on the other hand, the mechanical load of the hose package that occurs owing to robots arm motion should be as far as possible little, thereby it is as much as possible little to keep wearing and tearing.
The torsional load of Chu Xianing especially can be damaged the service life of hose package at work, also can avoid torsional load in the following manner, arranges a rotation conjunction in the robot joint area, thereby can continue to keep hose package not have torsional load.The shortcoming of this mode is, has increased the size of robot joint area, heat can by between conjunction be passed to hose package from gas nozzle, thereby can hinder the discharge of from gas nozzle, carrying out welding heat.
Summary of the invention
The objective of the invention is to, a kind of hose package that is used for welding equipment is provided, it especially can bear and reverse, and does not still have long service life so that do not exist under the situation of rotating conjunction in the robot joint area.
In order to reach purpose of the present invention, hose package according to the present invention has feature as claimed in claim 1.
In hose package according to the present invention, the conduit wall of guiding channel has helical spring equipment, and described helical spring equipment has at least one helical spring coil.
In hose package according to the present invention, guiding channel thereby can sufficiently antitorque commentaries on classics, and then avoid the damageability load that external insulation layer or conductor equipment caused by torsional tension as much as possible.
According to a kind of favourable form of implementation, supporting construction has tubular bracket, and support is equipped with the torsion proof backplate.Herein, the task of support mainly is, backplate is constituted annular wall.For example, support can be made by plastic flexible pipe.The antitorque commentaries on classics wrappage of support is shaped as netted, and it is for example made by metal material or enough firm and very measuring body nonmetallic materials.
In an especially preferred form of implementation, supporting construction has helical spring equipment, helical spring equipment has at least one helical spring coil, the helical spring coil allows the hose package bending and has the enough antitorque commentaries on classics rigidity that are used to transmit the anglec of rotation at the machine man-hour, but can't cause the distorting stress of damageability to the external insulation of conductor equipment.
According to the size of the length of hose package and the gas nozzle anglec of rotation advantageously a plurality of helical spring coils of arranged concentric to form helical spring equipment.When the anglec of rotation on two direction of rotation is big, the opposite helical spring coil of two direction of windings can be set to form helical spring equipment.
Can be not advantageously the helical spring equipment self not be used as conductor equipment yet, hose package is minimized in the size of diametrically according to the quantity of the helical spring coil of forming helical spring equipment and layout.
In an especially preferred embodiment of hose package, with strength guiding device axially in the hop of helical spring equipment adjacent, that be in relaxed state, the annular gap is formed between the conduit wall of helical spring equipment and receive path, not only can unload torsional load for flexible insulated hose---just reduce torsional load, can also under limiting case, discharge flexible insulated hose fully according to the size of annular gap from the received torsional load of helical spring equipment.
Conduit wall preferably is made of conductor equipment.
In order to realize in the hop of helical spring equipment that helical spring equipment separates with the electricity of conductor equipment, in the annular gap, be provided with the skin of the insulation of the cover layer of insulation of helical spring equipment or conductor equipment.
For hose package being connected in welding equipment or circuit guide device, connector is equipped with on the circuit guiding end of hose package,, described connector is used for carrying out current delivery and strength guiding between bonding machine or circuit guide device and hose package.Therefore the circuit guiding end of hose package directly links to each other with the rotation connector, and the rotation connector can deflect in working in the robot joint and the twisting resistance that hose package or helical spring equipment are acted on is limited in the limiting value scope.
Hose package equipment according to the present invention has the described feature of claim 11.
Be furnished with junction apparatus according to this bright hose package equipment on its circuit guiding end, junction apparatus has the plug portion that is made of connector, and plug portion rotatably is contained in the fixed jack part that is used to connect wire guide equipment.Because junction apparatus is positioned on the circuit guiding end, just be positioned on the end of hose package, it is away from the robot joint, be positioned on the end of the heat transfer path that defines by hose package so hinder from robot joint derivation thermal resistance heat, that define by junction apparatus, this scheme can obviously derive the heat that produces better with respect to the rotation connector is installed on gas nozzle in the robot joint area
In addition, jack part has the housing parts that is configured to electric conductor equipment, housing parts has attachment in the annular gap between plug portion and block set, described bonded block not only is used for radial support but also be used for current delivery, and it can realize especially good heat transmission with plug portion by mating reaction in rotation connector zone.
