Referring to fig. 1 to 4, the welding gun guard provided by the present application is used for a welding apparatus, and includes a housing 101, an elastic member 102, a trigger member 103, and a plurality of trigger switches 104; one end of the housing 101 is connected to a welding gun 105; the trigger 103 includes an abutting portion 106 and a connecting portion 107, the abutting portion 106 is located in the housing 101, and the connecting portion 107 penetrates through the other end of the housing 101 and is connected to a body of the welding apparatus, specifically, a partial structure 108 of the body of the welding apparatus is shown in fig. 4.

The plurality of trigger switches 104 are mounted on the housing 101 and are arranged in the circumferential direction of the abutting portion 106 at intervals, each trigger switch 104 is connected with an alarm device and a protection program of the welding equipment, and each trigger switch 104 can correspond to at least one collision direction of the welding gun 105.

One end of the elastic element 102 is connected to the housing 101, and the other end of the elastic element 102 abuts against the abutting portion 106, so that the abutting portion 106 abuts against the plurality of trigger switches 104. Under normal working conditions, the abutting part 106 abuts against the plurality of trigger switches 104 at the same time, and at the moment, the protection programs of the alarm device and the welding equipment cannot be triggered; a gap is formed between the casing 101 and the trigger 103, and when the welding gun 105 collides in any circumferential direction and causes the elastic piece 102 to deform and bend, the elastic piece 102 can bend in the opposite direction of the direction to drive the casing 101 to swing relative to the trigger 103, so that the corresponding trigger switch 104 is far away from the abutting part 106, and at the moment, the trigger switch 104 can trigger an alarm and a protection program of the welding equipment.

The application provides a welding gun protection device, when the rifle head bumps, can utilize the deformation of elastic component 102 to drive the casing 101 of installing a plurality of trigger switch 104 and move for trigger 103 to change the laminating state between trigger 103 and the trigger switch 104 on the equidirectional, and then can trigger alarm device and welding equipment's protection procedure in all directions, in order to realize the multi-direction protection to the rifle head.

As shown in fig. 1 and 2, the elastic member 102 is a spring, and when the elastic force of the spring is too large, the spring is not easily bent and deformed, and the problem that the trigger switch 104 cannot be timely triggered is easily caused; when the spring force of the spring is too small, the sensitivity is too high, and the trigger switch 104 is frequently activated. The elastic force of the spring needs to be selected according to actual conditions.

When the direct front collision of the welding gun 105 occurs, the elastic member 102 is pressed to contract backwards, so that the plurality of trigger switches 104 are separated from the abutting part 106 at the same time, the alarm device can be triggered accordingly, and the protection effect on the welding gun 105 is further increased.

In the optional scheme of this embodiment, a plurality of mounting grooves 109 are formed in the outer side of the housing 101 to mount a plurality of trigger switches 104, and the plurality of mounting grooves 109 are communicated with the inside of the housing 101, so that the abutting portion 106 can abut against the contact of the trigger switch 104.

In this embodiment, the mounting groove 109 is opened on the outer side of the housing 101, and the notch of the mounting groove 109 faces to the outer side, so as to facilitate mounting of the trigger switch 104; on the other hand, only the contact of the trigger switch 104 needs to be in contact with the abutting part 106 in the housing 101, the whole trigger switch 104 does not need to be arranged in the housing 101, and the trigger switch 104 is installed by using the housing 101 with a certain thickness, so that the problems that the trigger switch 104 is positioned in the housing 101 and is easily extruded by the abutting part 106 under the action of the elastic part 102, and the trigger switch 104 is not easily separated from the trigger 103 when the welding gun 105 is collided are avoided.

In an alternative scheme of this embodiment, the abutting portion 106 is cylindrical, and one end of the connecting portion 107 is connected to the center of the end face of the abutting portion 106; the mounting grooves 109 are uniformly distributed on a predetermined circumference of the housing 101, and a center of the predetermined circumference is opposite to a center of the end surface of the abutting portion 106.

Referring to fig. 3, when the abutting portion 106 swings, the circumference of the end surface of the abutting portion 106 can be close to or away from the at least one trigger switch 104 uniformly distributed on the preset circumference, so as to trigger the alarm device in multiple directions, and further protect the welding gun 105 in multiple directions.

In an alternative scheme of this embodiment, the housing 101 includes a limiting part 110 and a main body part 111; the limiting part 110 is located at one end of the main body 111 far away from the welding gun 105, and the main body 111 encloses to form a cavity to accommodate the elastic part 102 and the abutting part 106; the connecting part 107 is cylindrical, and the cross-sectional dimension of the abutting part 106 is larger than that of the connecting part 107; the limiting part 110 is provided with a through hole 112, the connecting part 107 penetrates through the through hole 112, and the cross-sectional dimension of the through hole 112 is larger than that of the connecting part 107; the abutting part 106 abuts against the inner side of the limiting part 110; the mounting groove 109 is opened in the limiting portion 110.

In this embodiment, the trigger switch 104 is mounted on the limiting portion 110, and the limiting portion 110 can limit the abutting portion 106 with a large size in the housing 101; the through hole 112 formed in the stopper 110 is larger than the connecting portion 107, and the through hole 112 does not restrict the swinging of the connecting portion 107 when the housing 101 swings.

In an optional scheme of this embodiment, the main body 111 includes an enclosure portion 113, a connecting flange 114, and a cover 115; one end of the enclosing part 113 is connected with the limiting part 110, and the other end of the enclosing part 113 is connected with the connecting flange 114; the cover 115 is fastened to one side of the connecting flange 114 away from the surrounding portion 113, and detachably connected to the connecting flange 114, and the other side of the cover 115 is connected to the welding gun 105.

In this embodiment, the housing 101 is formed with an opening with a larger size at a side close to the cover 115, so as to facilitate the trigger 103 and the elastic member 102 to be placed in the housing 101, and the cover 115 is detachably connected to the connecting flange 114, so as to facilitate the dismounting operation of the device; the other side of the cover 115 may be formed with a forked shaped connector for connection with the welding gun 105.

In this embodiment, referring to fig. 5 to 7, the limiting gap may have various structures, and is not limited to the groove structure shown in fig. 2 and 5, but the various structures should satisfy one point: preventing the housing 101 from rotating about the axis of the housing 101 relative to the trigger 103; and the spacing gap and the spacing pin 117 cannot affect the relative oscillation between the housing 101 and the trigger 103 in a predetermined direction (the illustrated structure is a front-back direction, the front corresponds to the direction of the welding gun 105, and the rear corresponds to the body of the welding apparatus) in which the housing 101 oscillates relative to the trigger 103. For example, when the two ends of the spacing gap in the preset direction are connected to form a closed structure (corresponding to fig. 6), the closed structure needs to leave a sufficient swing space for the spacing pin 117 and a space for the spacing pin 117 to move back; when the two ends of the spacing gap in the predetermined direction are open (corresponding to fig. 7), the spacing pin 117 may be partially or completely located in the gap, i.e., there is no factor affecting the swinging and retreating movement of the spacing pin 117.

Specifically, as shown in fig. 2 and 5, the abutting portion 106 is provided with a limit groove 116 (one of the structural forms of the limit gap), the notch of the limit groove 116 faces away from the welding gun 105, and the retreat distance of the limit pin 117 is larger; the cross section of the limiting groove 116 is arched parallel to the groove depth direction of the limiting groove 116; the housing 101 is formed with a limit pin 117 inserted in the limit groove 116, at least one side wall of the limit pin 117 facing the limit groove 116 is an arc surface, and the side wall of the limit pin 117 can enter the limit groove 116 from the notch of the limit groove 116 or be away from the limit groove 116.

In this embodiment, specifically, the limit pin 117 shown in fig. 2 and 5 is cylindrical, and is inserted into the pin hole 121 of the housing 101, the limit groove 116 formed in the abutting portion 106 can be clamped on the arc surface of the limit pin 117, the groove bottom of the limit groove 116 is also an arc surface, the limit groove 116 can slide relative to the arc surface of the limit pin 117, the friction force is smaller, the two can be prevented from being jammed, and the swing of the trigger 103 to trigger the trigger switch 104 is not affected.

Optionally, the limit pin 117 may also be configured as a structure having an arc surface, such as a sphere or an ellipsoid, and only the arc surface of the structure faces the groove bottom.

In an alternative solution of this embodiment, the cross section of the limiting groove 116 is in the shape of a minor arc arch, and the radius of the arc of the minor arc arch is not less than the radius of the arc of the limiting groove 116.

The cover 119 is detachable from the body of the welding apparatus via a mounting flange 120, facilitating the assembly and disassembly of the device. The cover 119 has a wide range of enclosure, and can house the stationary trigger 103 therein and also house the swinging housing 101 therein.
