Referring to fig. 1, fig. 1 is a diagram of an automatic stud welding gun 10 according to an embodiment of the present invention. As shown in fig. 1, an embodiment of the present invention provides an automatic stud welding gun 10 including a nail assembly 110, a feed assembly 120, a conductive collet 130, and a receiver 140; receiver 140 is connected to a first end of the tack assembly 110; the conductive clip 130 is connected to the nail assembly 110 through the receiver 140; the feeder assembly 120 is connected to the spike assembly 110 by a receiver 140; the feeder assembly 120 is used to deliver studs to the receiver 140; the conductive collet 130 is used for clamping the stud and protruding the stud by a fixed length; the top nail component 110 comprises a gun barrel 111, a top nail air cylinder 112, a top nail piston 113 and a limit piston 114; the nail ejecting cylinder 112 is movably arranged in the gun barrel 111; the top nail piston 113 and the limit piston 114 are movably arranged in the top nail cylinder 112 and can move in the top nail cylinder 112; one end of the top nail piston 113 sequentially penetrates through the limiting piston 114 and the first end of the top nail cylinder 112; the limit piston 114 is used for limiting the distance of the nail ejecting piston 113 entering the receiver 140; the nail piston 113 is used to push the stud into the conductive collet 130.
In the present embodiment, the receiver 140 has three channels, the three channels may be a first channel, a second channel, and a third channel, corresponding outlets of the first channel, the second channel, and the third channel are connected to the nail ejecting assembly 110, the feeding assembly 120, and the conductive chuck 130, respectively, and the three channels intersect inside the receiver 140. The receiver 140 is connected to the first end of the top pin assembly 110, i.e., the receiver 140 is connected to the first end of the top pin cylinder 112 of the top pin assembly 110, and the first channel of the receiver 140 is in communication with the first end of the top pin cylinder 112. The feeding assembly 120 is communicated with the second channel, meanwhile, the conductive chuck 130 is communicated with the third channel, and a stud to be welded is sent into the second channel from the feeding assembly 120 and automatically enters the third channel, and at the moment, the stud is in a state to be sent. The top pin piston 113 in the top pin assembly 110 may reach the third channel via the first channel and feed the stud into the conductive collet 130 via the third channel, and the conductive collet 130 may then clamp the stud such that the stud is transformed from a state to be fed into a state to be welded.
The conductive chuck 130 may be connected to the receiver 140 through a locking nut, and a dust-proof sleeve may be installed between the receiver 140 and the stud assembly 110 to prevent welding slag, oil contamination, and dust in the environment from entering the interior of the automatic stud welding gun 10 through a gap between the stud cylinder 112 and the gun barrel 111, thereby preventing the movement of the stud cylinder 112 from being affected.
In one embodiment, referring to fig. 1, the top pin piston 113 includes a top pin rod 1131 and a tail piston 1132; one end of the top pin rod 1131 is fixedly connected to the tail end piston 1132, and the other end of the top pin rod 1131 penetrates through the limit piston 114 and the first end of the top pin cylinder 112 and can enter the receiver 140; the tail piston 1132 may abut against an end of the limit piston 114 away from the receiver 140.
In this embodiment, as the spike piston 113 moves toward the receiver 140, the distance the spike rod 1131 enters the receiver 140 gradually increases. When welding a stud of any length, the pin 1131 may push the stud through the receiver 140 and into the conductive clip 130, and the pin 1131 also enters the conductive clip 130. When the ejector pin rod 1131 sends the stud into the welding position, the distance that the ejector pin rod 1131 enters the receiver 140 at this moment increases to the current maximum value, the tail end piston 1132 can abut against one end of the limiting piston 114 far away from the receiver 140, and then the limiting piston 114 limits the ejector pin piston 113, so that the distance that the ejector pin rod 1131 enters the receiver 140 is too large, and the length that the ejector pin rod 1131 sends the stud into the conductive chuck 130 is the length suitable for welding.
In one embodiment, the nail cylinder 112 includes a first cylinder 1121 near an end of the receiver 140 and a second cylinder 1122 remote from an end of the receiver 140; one end of the first cylinder 1121 is connected to one end of the second cylinder 1122; the first cylinder 1121 has a larger inner diameter than the second cylinder 1122.
In the present embodiment, the nail cylinder 112 is composed of a first cylinder 1121 and a second cylinder 1122 having two strokes and different inner diameters, and the first cylinder 1121 and the second cylinder 1122 are in communication, that is, a part of the inner diameter of the nail cylinder 112 close to the receiver 140 is larger than a part of the inner diameter of the nail cylinder far from the receiver 140, and when the stopper piston 114 and the nail piston 113 are not installed, the compressed air can reach the second cylinder 1122 from the first cylinder 1121 without hindrance.
In one embodiment, the limit piston 114 is disposed in the first cylinder 1121, and the tail piston 1132 is disposed in the second cylinder 1122; one end of the restraining piston 114 near the receiver 140 may abut to one end of the first cylinder 1121 near the receiver 140; the end of the restraining piston 114 near the second cylinder 1122 may abut the end of the first cylinder 1121 away from the receiver 140.
In this embodiment, the limit piston 114 is disposed in the first cylinder 1121 with a larger inner diameter, and the nail piston 113 is disposed in the second cylinder 1122 with a smaller inner diameter, so that the limit piston 114 can move back and forth in the first cylinder 1121, meanwhile, the nail rod 1131 of the nail piston 113 penetrates through the limit piston 114, and the tail end piston 1132 can drive the nail rod 1131 to move back and forth in the second cylinder 1122. In consideration of air tightness, the side wall of the limit piston 114 needs to abut against the side wall of the first cylinder 1121, that is, the outer diameter of the limit piston 114 needs to be less than or equal to the inner diameter of the first cylinder 1121; correspondingly, the sidewall of the tail piston 1132 needs to abut against the sidewall of the second cylinder 1122, i.e. the outer diameter of the tail piston 1132 needs to be smaller than or equal to the inner diameter of the second cylinder 1122. Since the inner diameter of first cylinder 1121 is greater than the inner diameter of second cylinder 1122, the outer diameter of tail piston 1132 needs to be smaller than the outer diameter of limit piston 114. In order to achieve the effect of limiting the nail pushing piston 113 by the limiting piston 114, the outer diameter of the limiting piston 114 may be set in two parts, specifically, the outer diameter of a part of the limiting piston 114 close to the receiver 140 may be set to be adapted to the inner diameter of the first cylinder 1121, and the outer diameter of a part of the limiting piston 114 far from the receiver 140 may be correspondingly set to be adapted to the inner diameter of the second cylinder 1122.
Furthermore, referring to fig. 2, an end of the limiting piston 114 away from the receiver 140 may enter the first cylinder 1121, and when a distance that the end of the limiting piston 114 away from the receiver 140 enters the first cylinder 1121 is a maximum value, due to the inner diameter limitation, a portion of the limiting piston 114, which has an outer diameter adapted to the first cylinder 1121, may abut against an end of the second cylinder 1122 close to the receiver 140, at this time, when the tail end piston 1132 abuts against the limiting piston 114, a distance that the ejector pin 1131 enters the conductive collet 130 through the receiver 140 is a minimum value, and then a stud with a larger length may be accommodated in the conductive collet 130 for welding, where the length of the stud is the first length.
When welding a stud, the stud needs to be pushed out of the conductive chuck 130 by a specific length, and for studs with different lengths, the specific length needs to be consistent under the same working scene. Thus, when welding a second length of stud (the second length being less than the first length), referring to FIG. 3, the distance the pin shank 1131 enters the conductive collet 130 through the receiver 140 is correspondingly increased to push the shorter stud of the second length out a particular length. Accordingly, at this time, an end of the limit piston 114 close to the receiver 140 abuts against an end of the first cylinder 1121 close to the receiver 140, so that the tail piston 1132 abuts against the limit piston 114 and extends the top pin 1131 to the maximum length, and the distance that the top pin 1131 enters the conductive chuck 130 through the receiver 140 is the maximum. The movement range of the tail end piston 1132 in the second cylinder 1122 can be changed by the movement of the limiting piston 114 in the first cylinder 1121 and the abutting of the two ends, and when short stud welding is required, the limiting piston 114 does not limit; when longer stud welding is required, the limiting piston 114 limits the tail end piston 1132, so that the distance from the top nail rod 1131 to the conductive chuck 130 through the receiver 140 changes, and the effect of being compatible with the lengths of the two welding studs is achieved.
In one embodiment, the automatic stud gun 10 further includes an electrical transmission assembly 150, a linear voice coil motor 160, and a grating displacement encoder 180; the electric transmission assembly 150 is electrically connected with the linear voice coil motor 160, the electric transmission assembly 150 is electrically connected with the top nail cylinder 112, and the electric transmission assembly 150 is electrically connected with the grating displacement encoder 180; the linear voice coil motor 160 is connected to the second end of the nail cylinder 112 and is used for driving the nail cylinder 112 to move; the grating displacement encoder 180 is disposed below the gun barrel 111 and is used for monitoring the displacement of the nail ejecting cylinder 112.

After the linear voice coil motor 160 is electrically connected to the electrical transmission assembly 150, it can drive the stud cylinder 112, the receiver 140, the conductive chuck 130 and the stud clamped in the conductive chuck 130 to perform a series of welding operations, such as striking, drawing, holding, upsetting, etc. Meanwhile, the grating displacement encoder 180 can detect the displacement of the nail pushing cylinder 112 and feed back the displacement to the driver of the automatic stud welding gun 10 in real time through the electric transmission assembly 150, so as to perform closed-loop feedback on the transmission operation of the voice coil motor.

Meanwhile, the electric connecting block 151 can introduce compressed air into the top nail air cylinder 112, and the top nail piston 113 and the limiting piston 114 are controlled by the compressed air, so that the top nail piston 113 and the limiting piston 114 can move according to welding requirements, and the welding requirements of studs with two lengths are met.
