The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 to 3, the present invention provides a welding device for a bottom beam fixing block used in a sewing machine, which includes a bottom plate 6, and a set of guide rails 8 is disposed on one side of the front end of the bottom plate 6.

The guide rail 8 is connected with a sliding block 7 in a sliding mode, and the top of the sliding block 7 is welded with a mounting plate 9. A bottom beam positioning seat 10 is welded at the front end of the top of the bottom plate 6 and at one side of the guide rail 8, and a mechanical arm 11 is installed at one end of the bottom beam positioning seat 10. Wherein, be equipped with welder on the arm 11, vibration dish 1 is installed to the rear end of bottom plate 6. The top of the vibration disk 1 is welded with a conveying rail 2, and the conveying rail 2 is positioned at the front end of the bottom plate 6 and extends to the front of the mounting plate 9.

As shown in fig. 1, a connecting plate 4 is welded to one side of the mounting plate 9, and a crank 12 is provided inside the connecting plate 4. The connecting rod 20 is movably connected to the front end of the crank 12, the connecting plate 4 provides a mounting point for the crank 12, and the crank 12 drives the connecting rod 20 to rotate when the crank 12 performs circular motion for a driving part.

In fig. 2, a restraint plate 16 is provided at a central position inside the mounting plate 9, and spacers are adhered to both upper and lower ends of a surface of the restraint plate 16, which is in contact with the mounting plate 9. It should be noted that the spacer ensures that a certain space is left between the constraint plate 16 and the mounting plate 9, so as to provide space for the movement of the bolt 18 without interference.

In the present embodiment, the restriction plate 16 is provided with a second through hole 17. Wherein the second through hole 17 is divided into a vertical section and a horizontal section. Specifically, the horizontal section of the second through hole 17 is connected with the top of the vertical section, and the length of the vertical section of the second through hole 17 is one half of the length of the horizontal section. In addition, the bolt 18 is moved along the second through hole 17 by the cooperation of the restriction plate 16 and the first through hole 15 of the slide plate 23. Since the second through holes 17 are formed in both the horizontal section and the vertical section, the bolts 18 can perform vertical movement as well as horizontal movement.

As shown in fig. 2, fixing strips 19 are welded to both upper and lower ends of the inside of the mounting plate 9. A sliding plate 23 is connected in the fixed strip 19 in a sliding manner, the center of one end of the sliding plate 23 is movably connected with the tail end of the connecting rod 20, and the sliding plate 23 is movably connected with the connecting rod 20. When the connecting rod 20 moves, the sliding plate 23 is driven to move in the fixing strip 19, and the fixing strip 19 provides a limit for the sliding plate 23, so that the sliding plate 23 cannot fall off, and the horizontal movement of the sliding plate 23 can be realized.

In this embodiment, the sliding plate 23 is provided with a first through hole 15, and the first through hole 15 is inclined along a diagonal line of the sliding plate 23. The upper inclined end of the first through hole 15 overlaps the second through hole 17, and the diameters of the first through hole 15 and the second through hole 17 are equal. In practical applications, when the sliding plate 23 moves horizontally, the bolt 18 moves along the opening shape of the second through hole 17 through the cooperation of the first through hole 15 and the second through hole 17.

A bolt 18 is movably sleeved in the first through hole 15, and a fixed shaft 14 is vertically arranged at the front end of the bolt 18. The bottom end of the fixed shaft 14 is fixedly connected with the taking head 13, and the bolt 18 can realize high-low movement and horizontal movement, so that the fixed shaft 14 descends and the taking head 13 at the end part of the fixed shaft adsorbs the fixed sheet. And then the fixing plate rises into the horizontal section of the second through hole 17 to move forwards, and the fixing plate is put on the bottom beam positioning seat 10.

Meanwhile, a rectangular through hole 5 is formed in the top of the bottom plate 6 and right below the sliding block 7, and a threaded sleeve 22 is welded at the bottom of the sliding block 7. The threaded sleeve 22 extends into the bottom plate 6 through the rectangular through hole 5, the driving screw 21 is installed in the bottom plate 6, and the driving screw 21 is movably sleeved with the threaded sleeve 22. In practical application, the threaded sleeve 22 is driven to move by the driving screw 21, so that the sliding block 7 further moves on the guide rail 8, the whole mounting plate 9 moves forwards, and the fixing plate can reach the bottom beam positioning seat 10.

The utility model discloses a theory of operation:

when the device is actually used, the fixed sheet is fed through the vibrating disk 1 (the model is BY-JD), reaches the front of the mounting plate 9 along the conveying track 2, the crank 12 drives the connecting rod 20 to rotate at the moment, and the connecting rod 20 further drives the sliding plate 23 to horizontally move in the fixed strip 19;

when the sliding plate 23 moves horizontally, the bolt 18 moves along the opening shape of the second through hole 17 by the matching of the first through hole 15 and the second through hole 17. Because the second through hole 17 is arranged on the horizontal section and the vertical section, the bolt 18 can realize the movement in the vertical direction and the movement in the horizontal direction, so that the fixed shaft 14 descends and the fixed plate is adsorbed by the workpiece taking head at the end part of the fixed shaft;

and then the fixing piece rises into the horizontal section of the second through hole 17, the threaded sleeve 22 is driven to move through the driving screw 21, the slide block 7 is further driven to move on the guide rail 8, the whole mounting plate 9 is driven to move forwards, the fixing piece is thrown onto the bottom beam positioning seat 10, and finally the bottom beam and the fixing piece are welded through a mechanical arm 11 (the model is CRP-RH14) with a welding gun.
