Abstract

This new-type light welding electrode holder features that insulative protecting unit is fixed to elastic, electrically conductive jaws which is exposed before, making it more safe and avoiding damage to workpiece caused by occasional collision.

Description

Light electrode holder

The present invention relates to a kind of soldering appliance, is the electrode holders that manual electric arc welding is used.

In factory, long-term custom is used a kind of electrode holders of simple light, its jaw electric conductor is elongated, and expose outside, though operation easily, but unfavorable safety in production, electric conductor also can often collide work, damage and produce arc crater ... because this kind electrode holders, electric conductor length is above 80 millimeters, sectional area is thinner, shape has three first bar types, unit's rod is knockdown with angle section, unit's rod is knockdown with the half dollar pipe, two semi-ring formulas with flat section bar formula because elasticity is better, spring is not set on the soldering turret, its clamping welding rod is to realize by the distortion elastic force of electric conductor, its profile at every clamping welding rod once will be out of shape once, and distortion is frequent, and processing such as should not hole again on the elongated upper jaw conductor, otherwise will destroy elastic force and lose intensity, thereby bring difficulty to insulating shield is set ..., in existing technology, imagination is also arranged on the jaw electric conductor, the position of contact electrode does not apply coatings, the spraying haydite, plastic-blasting, enamel, or with it thermosetting in bakelite, above method applies the position first and can not accurately control, thus influence conduction and normal the use; Coating material often fragility is big, easily avalanche with peel off, be to be unable to undergo jaw electric conductor frequent deformation; Moreover after jaw uses to a certain degree, can be out of shape excessively, can reuse after must hammering proofreading and correct, well imagine, with above-mentioned insulation is in the wrong can not be in company with hammering ...

The objective of the invention is in order to overcome deficiency of the prior art, and a kind of light electrode holder that the elastic nip electric conductor of insulation protective hood is arranged is provided, thereby it is safer that light electrode holder is used.

The present invention is achieved in that in elongate resilient jaw electric conductor appearance, the upper and lower jaw insulating shield that setting can be easy to loading and unloading, and its material adopts known high temperature resistant, flame-retardant insulating material; The fastener of its insulating shield is in the knee at the elasticity position of jaw electric conductor, crotch, shape sudden change place, adopt fasteners such as pressing plate, clamp, hook, anchor ear, bundle silk, Spring Card, adopt to hang, press, embrace, forms such as card, hook come fastening it, fastening very convenient, do not damage elastic force and breakdown strength simultaneously;

According to same design of the present invention: removably insulating shield is the non-resilient position on the elastic nip electric conductor, be jaw foremost, rearmost end, do not influence screw, silk, boss, concave station, groove and other mosaic texture that the position of the elastic force and the strength of materials processes, with fastener fastening again it.

In addition, can be at the fastening position of elastic nip electric conductor and insulating shield, the 0.5-15 mm clearance is set, be the strain gap, utilize the fastener constringency cleft, make and produce the elasticity adhesion between the two, distortion when making guard shield can follow electric conductor work, synchronously consistent, under the distortion situation, also can fit, loosening and separate.Its fastener is generally bolt, voussoir, and lever construction is pricked silk etc., after the jaw electric conductor uses distortion excessive, unloads insulating shield with regard to recoverable, and is very convenient and practical.

The present invention compares with original technology: the present invention does not damage the elasticity and the intensity of jaw electric conductor, insulating shield can be fitted on the elastic nip electric conductor reliably, having changed light electrode holder does not have the situation of jaw insulating shield, because it is fastening that elastic gap is set, can not resemble other traditional electrical soldering turret because of expanding with heat and contract with cold, and make protective cover loosening, even damage, the service life of soldering turret prolonged greatly.

Description of drawings is as follows: 1, go up the elastic nip electric conductor; 2, following elastic nip electric conductor; 3, upper jaw insulating shield; 4, lower jaw insulating shield; 5, fastener; 6, handle; 7, mosaic texture fastener; 8, elastic gap.

Embodiment one: a kind of light electrode holder, its insulating shield is to be fastened on the elasticity position, because the shape of guard shield is identical with the jaw shape, only be provided with the fastening gap of simple elasticity, thereby make and fasteningly become simple and reliable stable, and only set up fastener at a place, the jaw insulating shield just can not rotate, loosening and displacement.It is arc that upper shield can be processed into the same with the jaw shape, and lower shield can be copied lower jaw bifurcation type shape, and it is dichotomous to be processed into the bifurcation type, be convenient to like this insulating shield and jaw can be better synchronously strain with reset.Though the entire product length overall is 290 millimeters, 30 millimeters of handle diameters, length is 130 millimeters, and the exposed position of elastic nip electric conductor reaches 160 millimeters, is 3-4 times of common non-resilient jaw electric conductor length, under the situation of such overlength, only each needs a fastener to the insulating shield of upper and lower jaw, just separate fastening steadily, with applying, and can also deform in same pace with reset.

Embodiment two: a kind of light electrode holder, its jaw insulating shield are fastening two kinds of fastening forms that combine in fastening and non-resilient position, elasticity position and the structure of depositing.

Embodiment three: a kind of light electrode holder, its insulating shield are the inelastic body positions that is fastened on the rear end of jaw.Because the crooked position of insulating shield is not only similar but also corresponding with the jaw crooked position, therefore can not move forward and backward, so only need at the rear portion of jaw anchor ear, fasteners such as bolt, with regard to energy simply fastening it.If also be provided with the strain gap, this structure will be more perfect, insulating shield can with the synchronous strain of jaw, and fit closely.

Embodiment four: a kind of light electricity pincers, the form structure of fastening insulating shield of two ends while before and after jaw.

Owing to be provided with the jaw insulating shield dexterously, do not damage original advantageous characteristic of product, improved the security of work, make the workman use for a long time light soldering turret, the scientific and technological epoch of not developed by leaps and bounds now treat coldly, and can continue service society muchly.
