Illustratively, the substrate 1 in the present embodiment may be formed in a rectangular plate shape, four corners of which may be formed with through holes in advance so as to fix the substrate 1 by screws. Therefore, the arrangement of the substrate 1 makes the device modularized, and the rest parts can be preset on the substrate 1, so that the position transfer and the rapid installation of the device are facilitated, and the time consumed by equipment debugging before process implementation is reduced.

With particular reference to fig. 1 and 2, fig. 2 shows a processing application scenario of the device of fig. 1, in fact, fig. 1 and 2 show the structure of the components involved in the processing application scenario in its entirety, so in the above description, the structure and function of the substrate 1 are first described, and in the following description, the structure, connection relationship and working principle of the remaining components will be focused on.

The welding fixture for the automobile seat support steel wire assembly comprises a butt joint seat 2 for placing a butt joint piece and a positioning seat 4 for placing steel wires, wherein a plurality of groups of butt joint seats 2 and a plurality of groups of positioning seats 4 are arranged according to the shape of the automobile seat steel wire assembly, so that a placing platform is formed, and the automobile seat steel wire assembly is arranged on the upper end face of the placing platform.

For example, referring to fig. 4, fig. 4 is a schematic view showing the arrangement points of the plurality of docking seats 2 and the plurality of positioning seats 4 in the substrate 1 in the present embodiment; here, the arrangement points of the docking seat 2 and the positioning seat 4 shown in fig. 4 are merely illustrative of the arrangement points required for welding a certain type of "automobile seat support wire assembly", and in actual manufacturing, a user may adjust the number, size, height, inclination and arrangement points of the positioning seat 4 and the docking seat 2 according to different shapes of "automobile seat support wire assemblies", so that the device as a whole can adapt to different "automobile seat support wire assemblies".

Further, the positioning seat 4 and the docking seat 2 can be connected with the base plate 1 through clamping, screw fixing or bonding and the like, so that the positioning seat 4 and the docking seat 2 can be conveniently taken down, the position is changed and the like when different 'automobile seat support steel wire assemblies' are required to be adjusted.

Further, the docking station 2 includes a boss 201, a matching surface 202 is formed on an upper surface of the boss 201, and a shape of the matching surface 202 is adapted to that of the docking piece, so that the docking piece can be attached to the matching surface 202, and a positioning hole 203 is further formed in the boss 201.

For example, referring to fig. 5, fig. 5 is a schematic view of two different docking stations 2 in the present embodiment, and in order to more intuitively understand the commonality of the two different docking stations 2, fig. 5 shows the two docking stations in contrast.

As shown in fig. 5, the docking station 2 in the present device is formed by the boss 201, and when the boss 201 is placed on the substrate 1, the docking piece carried by the boss can be higher than the substrate 1, so that the welding gun can be conveniently welded, and there is no fear that the welding gun makes a false contact with the substrate 1.

In actual production, the matching surface 202 on the surface of the boss 201 needs to be manufactured according to the shape, the size and the required inclination of the butt joint part, and as shown in the embodiment, one of the two different matching surfaces 202 is in a step shape, and the other one is in an inclined plane shape; in practice, the mating surface 202 may be of any shape, the final purpose of which is to firmly place the abutment.

The aforementioned docking station 2 may be detachably connected to the base plate 1, so in the above example, the base plate 1 may be connected to the boss 201 through the positioning hole 203, specifically, a hole position corresponding to the positioning hole 203 is formed on the base plate 1, and the boss 201 is fixed by a pin, a bolt, a plug, or the like.

Further, the positioning seat 4 comprises a supporting column 401, a clamping groove 402 is formed in the upper surface of the supporting column 401, the shape of the clamping groove 402 is matched with that of the steel wire, the steel wire can be placed in the clamping groove 402, and the output end of the pressing mechanism 3 is correspondingly arranged with the clamping groove 402.

For example, referring to fig. 5, fig. 5 is one of the positioning seats 4 in the present embodiment, and other positioning seats 4 may be disposed with reference to fig. 5.

It should be noted that the positioning seats 4 in this embodiment are not identical, wherein the height, width, inclination, etc. of each positioning seat 4 are set depending on the shape of the "car seat support wire assembly"; it can be understood that, in practical implementation, the positioning seat 4 of the device needs to be adjusted differently according to different processing of the "automobile seat support wire assembly"; similarly, the shape of the clamping groove 402 needs to be set according to the actual processing of the "steel wire", and the general purpose is to adapt to the steel wire.

The welding fixture further comprises a plurality of groups of pressing mechanisms 3, the pressing mechanisms 3 are arranged in one-to-one correspondence with the positioning seats 4, and the output ends of the pressing mechanisms 3 are positioned above the positioning seats 4 and are used for pressing steel wires on the upper end faces of the positioning seats 4.

Referring to fig. 2, it can be seen from the figure that the fixing mode that the upper end surface of the positioning seat 4 and the pressing mechanism 3 are matched to clamp the steel wire is adopted, the steel wire is uniformly paved on the surface of the positioning seat 4 and then pressed down for clamping, so that inconvenience caused by irregular multi-bending of the steel wire can be avoided to a certain extent, and the problem of inconvenient clamping of the traditional bench vice is avoided; that is, the output end of the pressing mechanism 3, i.e. the part contacted with the steel wire, presses the steel wire from top to bottom, and meanwhile, the bottom of the steel wire is supported by the positioning seat 4, so that the steel wire can be stable in the processing process and cannot shake.

The compressing mechanism 3 is arranged in various modes, and the embodiment adopts a mechanical structure driven by a cylinder; specifically, the pressing mechanism 3 includes a base 301, a cylinder 302 and a pressing head 303 are rotatably installed on the base 301, and a piston rod of the cylinder 302 is in transmission connection with the pressing head 303 through a link mechanism, so that the piston rod of the cylinder 302 drives the pressing head 303 to move up and down.

Referring to fig. 7 and 8, fig. 7 and 8 are views of the pressing mechanism 3 viewed from the front and back, respectively, in the present embodiment; in this embodiment, when the piston rod of the cylinder 302 reciprocates, the link mechanism is driven to move, so that the pressing head 303 moves up and down, and therefore, when the pressing head 303 contacts with the "steel wire", downward pressure can be applied to the "steel wire" to firmly press the "steel wire" onto the positioning seat 4.

On the basis of the above, more specifically, the link mechanism comprises an extension rod 306 and a pull rod 307, wherein one end of the extension rod 306 is fixedly connected with the pressing head 303, the other end of the extension rod is rotationally connected with the base 301, one end of the pull rod 307 is rotationally connected with a piston rod of the air cylinder 302, and the other end of the pull rod is rotationally connected with the extension rod 306; the linkage mechanism further comprises a first mounting frame 304 and a second mounting frame 305, the first mounting frame 304 and the second mounting frame 305 are fixedly mounted on the base 301, the shell portion of the air cylinder 302 is rotatably mounted on the first mounting frame 304, and the end portion of the extension rod 306 is rotatably mounted on the second mounting frame 305.

According to the above description, it is conceivable that when the piston rod of the cylinder 302 is extended, a force toward the pressing head 303 is applied to the pull rod 307, but since both ends of the pull rod 307 are rotatably connected, the pull rod 307 applies an inclined pushing force to the extension rod 306 while rotating, and since one end of the extension rod 306 is rotatably connected to the second mounting frame 305, the extension rod 306 cannot advance and retreat in the axial direction, that is, only the pressing head 303 at one end of the extension rod 306 can swing up and down along with the extension rod 306.

As can be seen from the above description of the movement process, in this embodiment, the cylinder 302 is rotatably mounted on the first mounting frame 304, and the weights at two sides of the rotation position are hard to balance, so that the end of the piston rod of the cylinder 302 is easy to tilt, and the pressing head 303 is pulled to tilt, at this time, the extension rod 306 and the pressing head 303 face upwards, and when the piston rod of the cylinder 302 reciprocates again, the pressing head 303 cannot be driven to press down.

In order to avoid this, it is generally necessary to set the weight of the end of the piston rod beyond the housing portion of the cylinder 302, for example to increase the weight of the pressing head 303 or the extension rod 306, or to directly apply a weight to both, but this method is not only too costly, but also makes the inertia of the pressing head 303 too great, and it is easy to hit the "wire" during clamping, causing damage.

Therefore, in this embodiment, the above structure is improved, specifically, the link mechanism further includes a swinging rod 308, one end of the swinging rod 308 is rotatably connected to the piston rod of the air cylinder 302, and the other end is rotatably connected to the second mounting frame 305.

The end part of the piston rod of the air cylinder 302 is limited by the swinging rod 308, so that the whole air cylinder 302 is always in a nearly horizontal position, and when the piston rod of the air cylinder 302 stretches, the end part of the piston rod is guided by the swinging rod 308 to make a small-range circular arc movement, and the phenomenon that the end part of the piston rod is easy to tilt to pull the pressing head 303 to tilt is avoided.

Further, an adjusting bolt 309 is fixedly connected to the pressing head 303, an adjusting hole corresponding to the adjusting bolt 309 is formed in the extending rod 306, the adjusting bolt 309 penetrates through the adjusting hole, and locking nuts 310 are disposed at two ends of the adjusting bolt 309.

Referring to fig. 9, fig. 9 is a view of a portion where the pressing head 303 is connected to the extension rod 306 in the present embodiment, it can be seen from the drawing that the lock nuts 310 at both ends can be fixed to the adjusting bolts 309 and the pressing head 303 after being screwed down, and it is conceivable that when the position of the pressing head 303 needs to be adjusted, the position of the pressing head 303 can be adjusted by only unscrewing the lock nuts 310, and then screwing down the lock nuts 310 again.

Referring again to fig. 2, in accordance with the above description, for convenience of description, the part wire 5 and the butt piece 6 are shown as welded; it can be seen that when welding a plurality of steel wires 5 and the butt joint piece 6, the steel wires 5 are required to be placed on the positioning seat 4, then the pressing mechanism 3 is driven to press, so that the pressing mechanism cannot shake, and meanwhile, the butt joint piece 6 is placed on the butt joint seat 2, so that welding can be performed.

Other embodiments of the utility model will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure disclosed herein. This application is intended to cover any variations, uses, or adaptations of the utility model following, in general, the principles of the utility model and including such departures from the present disclosure as come within known or customary practice within the art to which the utility model pertains. It is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the utility model being indicated by the following claims.
