Abstract
The utility model relates to grounding pincers, which comprise an upper jaw and a lower jaw, wherein the upper jaw is matched with the lower jaw in a movable mode by a tensioning device; and a copper pipe sleeve into which a wire is inserted and a locking structure for locking the wire are arranged on the tail part of the lower jaw. According to the grounding pincers, the upper jaw is matched and clamped with the lower jaw by the tensioning device, so that the grounding pincers are connected with a welding piece reliably and firmly, and the stability of welding currents is high; and by the copper pipe sleeve on the tail part, the installation of the wire is facilitated, and the stability of currents of the grounding pincers can be ensured by the arrangement of the copper pipe sleeve and the locking structure, so that the welding quality of welding equipment is improved.
Description
Technical field
The utility model relates to technical field of welding equipment, relates in particular to a kind of ground connection pincers that are used in all kinds of electric welding equipments being connected with the ground wire of weldment that are applicable to.
Background technology
In at present common welding equipment, all be to connect a copper coin at the end of ground wire, when welding as earth plate; Copper coin is pressed on the weldment can carries out welding operation; But in welding process, the situation through earth plate and weldment loose contact take place in regular meeting causes welding current unstable; And then then weld seam is bad, and welding quality is relatively poor.
Summary of the invention
For solving above-mentioned technical problem, the utility model provides a kind of and can clamp with the ground connection that weldment firmly is connected, and guarantees that welding current is stable, helps improving welding quality.
The technical scheme of the utility model is; A kind of ground connection pincers with following structure are provided; It comprises upper jaw and lower jaw, and upper jaw and lower jaw are through the movable cooperation of tensioning apparatus, and the afterbody of lower jaw is provided with copper pipe cover that is used for the plug-in mounting lead and the locking mechanism that lead is locked.
After adopting said structure, the utlity model has following advantage:
Realize the clamping that matches of upper jaw and lower jaw through tensioning apparatus; Be connected reliable firm with weldment; The stability of welding current is better, and the copper pipe cover of afterbody is beneficial to conductor mounting, and the setting of copper pipe cover and locking mechanism can guarantee the current stabilization of ground connection pincers self; Like this, help improving the welding quality of welding equipment.
Preferable, described tensioning apparatus comprises screw mandrel and screw mandrel cover, and the lower end of screw mandrel is fixedly connected with lower jaw, and the screw mandrel cover is stuck on the upper jaw also free to rotate in the installing hole, and screw mandrel and screw mandrel external threading are connected.Tensioning apparatus is a screw structure, perhaps unclamps through screw mandrel cover and the threaded engagement realization upper jaw of screw mandrel and the clamping of lower jaw, and is simple in structure and easy to operate.
Preferable, the upper end of described screw mandrel cover also is provided with rotating disk.Rotating disk can make the rotation of screw mandrel cover more easy.
Preferable, the afterbody of upper jaw is provided with straight-arm, and lower jaw is provided with jack, and this straight-arm inserting is combined in the jack spacing to upper jaw.Under the guiding of straight-arm, can make the stable of relative position between upper jaw and the lower jaw, can guarantee that also the direction that both move is comparatively stable,
Preferable, described locking mechanism is meant that the afterbody of lower jaw is a sleeve, the copper pipe cover is a tight fit in the sleeve, and on sleeve, is provided with the screwed hole that connects the copper pipe cover.This structure can guarantee that the installation of copper pipe cover is comparatively reliable, and is convenient to receive lead.
Preferable, the afterbody of described lower jaw also is provided with the sheath of rubber material, and this sheath is enclosed within on the sleeve.Can play good protection to the joint of lead and copper pipe cover like this.
Description of drawings:
Fig. 1 is the structural representation of the utility model ground connection pincers;
The specific embodiment:
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
Shown in accompanying drawing 1, the utility model ground connection pincers, it comprises upper jaw 1 and lower jaw 2, and upper jaw 1 cooperates through the tensioning apparatus activity with lower jaw 2, and the afterbody of lower jaw 2 is provided with copper pipe cover 3 that is used for the plug-in mounting lead and the locking mechanism that lead is locked.
Wherein, the concrete structure of tensioning apparatus is following: it comprises screw mandrel 4 and screw mandrel cover 5, and the lower end of screw mandrel 4 is fixedly connected with lower jaw 2; On screw mandrel cover 5, be provided with boss; In the installing hole that screw mandrel cover 5 is inserted on the upper jaw 1, and then rivet pad on the screw mandrel cover 5 of installing hole below, so just can to screw mandrel overlap 5 and upper jaw 1 between play the axial limiting effect; Screw mandrel cover 5 just is stuck on the upper jaw 1 also free to rotate in the installing hole, then screw mandrel 4 and screw mandrel is overlapped 5 threaded engagement and is connected.
For ease of the rotation of screw mandrel cover 5, also be provided with rotating disk 6 in the upper end of screw mandrel cover 5.
Afterbody at upper jaw 1 is provided with straight-arm 7; Lower jaw 2 is provided with jack 2.1; Straight-arm 7 insertings are combined in the jack 2.1; Just can move up and down and play position-limiting action in the process, the position between upper jaw 1 and the lower jaw 2 is kept relative stability, so also can improve clamping effect weldment to upper jaw 1.
Above-mentioned locking mechanism is meant that the afterbody of lower jaw 2 is a sleeve 2.2, and copper pipe overlaps 3 tight fits and is embedded in sleeve 2.2, and on sleeve 2.2, is provided with the screwed hole 2.3 that connects copper pipe cover 3.When lead is installed, earlier lead is inserted in the copper pipe cover 3, just can cooperates with screwed hole then lead is held out against in copper pipe cover 3 with screw.
For joint between copper pipe cover 3 and lead are overlapped 3 with copper pipe carries out proper protection, also be provided with the sheath 8 of rubber material at the afterbody of lower jaw 2, this sheath 8 is enclosed within on the sleeve 2.2.
