The embodiment of the application provides a welding jig 100, and welding jig 100 includes revolving cylinder 10, locating plate 20, hold-down mechanism 30 and locating rod 40. The positioning plate 20 is connected to the rotary cylinder 10 and is driven by the rotary cylinder 10 to rotate, and a welding hole 21 is formed in the positioning plate 20; the pressing mechanism 30 comprises a pressing motor 31 and a pressing rod 32, and the pressing motor 31 is used for driving the pressing rod 32 to rotate back and forth; the positioning rod 40 is arranged on the positioning plate 20, at least part of the positioning rod 40 is exposed out of the welding hole 21, and the pressing mechanism 30 is used for locking or unlocking the positioning rod 40; at least two first positioning pins 22 are arranged on the positioning plate 20 along the axial direction of the positioning rod 40, first positioning holes 41 are arranged at positions of the positioning rod 40 corresponding to the first positioning pins 22, and the first positioning pins 22 are inserted into the first positioning holes 41. To solve the technical problem of complex structure of the existing welding jig 100.
The working principle of the welding jig 100 in this embodiment is as follows: sleeving the element 200 to be welded with a large volume on the positioning rod 40, assembling the element 300 to be welded with a small volume at a position corresponding to the welding hole 21, aligning the first positioning hole 41 on the positioning rod 40 with the first positioning pin 22 on the positioning plate 20, assembling the positioning rod 40 on the positioning plate 20, driving the pressing rod 32 to rotate and abut against one side of the positioning rod 40 departing from the positioning plate 20 by the pressing motor 31, and completing the assembly of the element to be welded.
After the components are assembled on the front surface of the positioning plate 20, the positioning plate 20 may be driven to rotate by the rotary cylinder 10 so that the rear surface of the positioning plate 20 is directly opposite to the welding mechanism.
Then, the welding head of the welding mechanism can weld the element to be welded through the welding hole 21, so that the technical problem that the welding head of the welding mechanism is inconvenient to weld from the front can be avoided.
To sum up, in the embodiment of the present invention, the positioning rod 40 is disposed on the positioning plate 20, the element 200 to be welded with a larger volume can be sleeved on the positioning rod 40, then the element 300 to be welded with a smaller volume is clamped between the element 200 to be welded with a larger volume and the positioning plate 20, then the rotary cylinder 10 drives the positioning plate 20 to rotate until the back surface of the positioning plate 20 is opposite to the welding mechanism, and the welding mechanism can weld the two elements to be welded through the welding hole 21 disposed on the positioning plate 20, so that the positioning mechanism of the element 300 to be welded with a smaller volume can be omitted, and the structural complexity of the welding jig 100 can be further reduced. In addition, by arranging at least two first positioning pins 22 on the positioning plate 20 and arranging the first positioning holes 41 on the positioning rods 40 to match with the first positioning pins, accurate positioning of the components to be welded can be realized, and the components to be welded are ensured to be positioned at the positions of the welding holes 21.
Specifically, the output shaft of the rotary cylinder 10 is connected to the positioning plate 20 for driving the positioning plate 20 to rotate. The rotary cylinder 10 may be directly connected to the positioning plate 20, or the rotary cylinder 10 may be indirectly connected to the positioning plate 20. The rotary cylinder 10 can drive the positioning plate 20 to rotate 180 degrees, so that one of the front or back of the positioning plate 20 is in contact with the welding mechanism.
Wherein, the pressing mechanism 30 is disposed on the side of the positioning plate 20, and when no component to be welded is disposed on the positioning plate 20, the pressing rod 32 is disposed on the side of the positioning plate 20 and is parallel to the axial direction of the positioning rod 40. After the elements to be welded are mounted on the positioning plate 20, the pressing motor 31 drives the pressing rod 32 to rotate by 90 degrees, at this time, the axial direction of the positioning rod 40 is perpendicular to the axial line of the pressing rod 32, and the pressing motor 31 abuts against the positioning rod 40 and the elements to be welded, after the positioning plate 20 rotates, the pressing rod 32 can ensure that the positioning rod 40 is always positioned on the positioning plate 20, and the positioning rod 40 and the elements to be welded sleeved on the positioning rod 40 are prevented from being separated from the positioning plate 20.
The pressing mechanism 30 may further include a return spring, in an initial state of the return spring, an axial direction of the pressing rod 32 is parallel to an axial direction of the positioning rod 40, and when the pressing motor 31 drives the pressing rod 32 to rotate, the pressing motor 31 may continuously press the return spring, so that the return spring is deformed. When the positioning rod 40 needs to be removed, the pressing motor 31 can stop working, and at this time, the return spring elastically returns to drive the pressing rod 32 to return to a position parallel to the positioning rod 40. By providing the return spring, the operating time of the pressing motor 31 can be shortened, thereby saving energy.
Further, in an embodiment of the invention, the welding jig 100 includes a valve core seat 50, and the valve core seat 50 is disposed in the welding hole 21 and detachably connected to the positioning plate 20.
Specifically, the valve core seat 50 can be made of a plastic material and disposed in the welding hole 21, so as to support the element 300 to be welded, which has a smaller volume. Because the temperature of the welding head of the welding mechanism is high, and welding chips and the like are generated during welding, the welding chips dropping on the valve core seat 50 can damage the valve core seat 50. The valve core seat 50 is detachably connected with the positioning plate 20, so that the valve core seat 50 can be conveniently replaced when the valve core seat 50 is damaged.
Further, as shown in fig. 5, fig. 5 is a schematic perspective view of the valve core seat 50 in fig. 1.

Specifically, the shape of the seat body 51 is matched with the shape of the welding hole 21, and the seat body 51 can be arranged in the welding hole 21 in an interference fit manner. The seat body 51 is provided with an avoiding hole 511 at the center, in this embodiment, the avoiding hole 511 is rectangular, or in other embodiments, the avoiding hole 511 may also be circular, trapezoidal, triangular, or the like.
The connecting portions 52 are long, two ends of the connecting portions 52 are respectively connected to two opposite side walls of the avoiding hole 511, and the connecting portions 52 are arranged in parallel at intervals to form a welding position between adjacent connecting portions 52, so that a welding head can conveniently pass through the welding position to contact with an element to be welded.
The positioning seat 53 is disposed on the connecting portion 52 to be supported by the connecting portion 52 and protrude from the base body 51, so as to position the to-be-welded component 300 with a smaller volume and prevent the to-be-welded component from shifting relative to the positioning plate 20.
As shown in fig. 4, the to-be-welded element 300 with a smaller volume in the present embodiment is in a rectangular box shape, the cross-sectional shape of the positioning seat 53 is also rectangular, and the to-be-welded element 300 with a smaller volume is sleeved on the positioning seat 53.
Further, as shown in fig. 4 and 5, a second positioning pin 531 is disposed on a side of the positioning seat 53 facing the positioning rod 40, a position-limiting hole 310 is disposed at a position of the to-be-welded element corresponding to the second positioning pin 531, and the second positioning pin 531 is inserted into the position-limiting hole 310 to limit a position of the to-be-welded element on the positioning seat 53, so as to prevent the to-be-welded element from shifting.
Alternatively, the second aligning pin 531 may be provided to protrude by a smaller height with respect to the aligning base 53 than the first aligning pin 22 protrudes with respect to the aligning plate 20. Therefore, the small-size element 300 to be welded and the positioning seat 53 can be conveniently connected in a matching manner.
Further, as shown in fig. 4, a plurality of second positioning holes 42 are formed in the positioning rod 40, and the plurality of second positioning holes 42 are spaced apart from each other in the axial direction of the positioning rod 40.
Specifically, the positioning rod 40 is provided with a first positioning hole 41 aligned with the positioning plate 20 and a second positioning hole 42 matched with the to-be-welded element 200 with a larger volume, and when the to-be-welded element is sleeved on the positioning rod 40, the to-be-welded element can be positioned and limited on the positioning rod 40 through the matching of the second positioning hole 42 and the alignment hole on the to-be-welded element, so as to ensure that the to-be-welded element 200 with a larger volume is accurately aligned with the to-be-welded element 300 with a smaller volume.
Further, as shown in fig. 1 to 5, the welding jig 100 includes a supporting frame 60, the positioning plate 20 is disposed in the supporting frame 60, an outer side wall of the positioning plate 20 is spaced apart from an inner side wall of the supporting frame 60, mounting holes are disposed on opposite surfaces of the supporting frame 60 and the positioning plate 20, the welding jig 100 includes a spring 70, and opposite ends of the spring 70 are inserted into the mounting holes. In this way, the positioning plate 20 can be hung on the support frame 60, thereby facilitating adjustment of the positional relationship of the positioning plate 20 with respect to the rotary cylinder 10.
Since the element 200 to be welded with a large volume is cylindrical, when the element to be welded and the positioning rod 40 are placed on the positioning plate 20, the contact area between the element to be welded and the positioning plate 20 is small, and the element to be welded is easily deformed when the element to be welded is pressed by an external force.
Therefore, in this embodiment, as shown in fig. 4, a height limiting block 23 may be disposed on the positioning plate 20, a positioning groove 43 is disposed on the positioning rod 40 at a position corresponding to the height limiting block 23, and the height limiting block 23 is inserted into the positioning groove 43. Therefore, the positioning rod 40 can be limited at a certain height by utilizing the abutting action of the height limiting block 23 clamped between the positioning plate 20 and the positioning rod 40 on the positioning rod 40, so that a gap is reserved between the positioning rod 40 and the positioning plate 20, and the situation that the positioning rod 40 is close to the positioning plate 20 and abuts against the element to be welded to deform is avoided.
