[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.
[0020] In this embodiment, for the assembly and welding operation of the lock rod and the lock head of the container, a lock head welding positioning device is designed. Among them, the structure of the lock head 16 is as Figure 3 shown, including a lock seat connecting portion and an inserting rod 165. The inserting rod 165 is cylindrical and is used to insert into the lock rod. A limit disk 166 with a diameter larger than the outer diameter of the inserting rod 165 is formed at the connection between the lock seat connecting portion and the inserting rod 165. The lock seat connecting portion includes a first fixing block 161 and a second fixing block 162 on the same side, and a third fixing block 163 and a fourth fixing block 164 on the other side. A gap is left between the first fixing block 161 and the second fixing block 162, and the two form a bifurcated structure. A gap is left between the third fixing block 163 and the fourth fixing block 164, and the two also form a bifurcated structure. Based on the above structure of the lock head 16, the feeding mechanism of this embodiment is designed.
[0021] As Figure 1As shown in the figure, the whole set of lock head welding positioning device mainly includes a frame 1, a support frame 2 arranged on one side of the frame 1, a mounting bench 4 arranged on the other side of the frame 1, a lock head fixing mechanism arranged on the mounting bench 4, and a lock head feeding mechanism. At least two support frames 2 are arranged at intervals. An open groove is formed at the top of the support frame 2. A vertical limiting plate is arranged at the tail end of the frame 1. The lock rod 3 is inserted into the groove at the top of the support frame 2, and the tail end of the lock rod 3 abuts against the vertical limiting plate.
[0022] As Figure 2 shown in the figure, the lock head fixing mechanism includes a bottom plate 6, a slide rail 7, a propulsion cylinder 5, a slider 8, a slide plate 9 and a lock head limiting seat 12. Among them, the bottom plate 6 is fixedly installed on the top of the mounting bench 4. A slide rail 7 is arranged on the top surface of the bottom plate 6 along the length direction of the lock rod 3. A slider 8 is arranged on the slide rail 7. The bottom of the slide plate 9 is fixedly connected to the slider 8. Figure 2 In the shown direction, a push plate 10 is vertically arranged at the left end of the slide plate 9. The push plate 10 is fixedly connected to the slide plate 9. A lock head limiting seat 12 is arranged at the right end of the slide plate 9. A cylinder fixing seat is arranged at the left end of the bottom plate 6. The propulsion cylinder 5 is installed on the cylinder fixing seat. The telescopic direction of the push rod 11 of the propulsion cylinder 5 is the same as the length direction of the lock rod 3. The end of the push rod 11 is fixedly connected to the push plate 10. The lock head limiting seat 12 is used to receive the lock head 16 that falls from the discharge port of the feeding mechanism. In this embodiment, the limiting seat 12 is mainly composed of a base plate at the bottom and four enclosing plates. The base plate is fixed on the slide plate 9. The four enclosing plates are perpendicular to the base plate and enclose a rectangular cavity structure with an open top, as Figure 2 shown in the figure. The four enclosing plates are divided into a first enclosing plate and a third enclosing plate arranged oppositely, and a second enclosing plate and a fourth enclosing plate arranged oppositely. Among them, the third enclosing plate is closest to the lock rod 3. The first enclosing plate is higher than the other three enclosing plates. The first enclosing plate is used to limit the lock seat connecting part of the lock head 16. The top surface of the third enclosing plate forms a concave arc surface. The third enclosing plate is used to support the limiting disc 166 of the lock head 16. The first fixing block 161 and the second fixing block 162 of the lock head 16 are supported by the second enclosing plate. The third fixing block 163 and the fourth fixing block 164 of the lock head 16 are supported by the fourth enclosing plate. The insertion rod 165 of the lock head 16 faces the side of the lock rod 3.
[0023] A material supporting seat 15 for supporting the insertion rod 165 is also arranged beside the limiting seat 12. The top of the material supporting seat 15 forms a concave arc structure. A material supporting cylinder 14 is arranged at the bottom of the material supporting seat 15. The material supporting cylinder 14 is fixedly installed on the side of the mounting bench 4. The push rod of the material supporting cylinder 14 moves up and down telescopically. The push rod of the material supporting cylinder 14 is fixedly connected to the bottom of the material supporting seat 15. By moving the push rod of the material supporting cylinder 14 upward, the material supporting seat 15 is pushed to support the insertion rod 165 of the lock head 16 that has fallen into the limiting seat 12.
[0024] The lock head feeding mechanism is as Figure 4 andFigure 5 As shown in the figure, it mainly includes a fixed bracket 13, a feeding trough and a discharging cylinder. The bottom end of the fixed bracket 13 is fixed on the mounting bench 4. The upper end of the fixed bracket 13 forms a feeding trough. The feeding trough has an inclination relative to the plane where the bottom plate 6 is located. The feeding trough is used to accommodate a plurality of lock heads 16 arranged in sequence. The inclined feeding trough facilitates the lock heads 16 to slide down along the feeding trough under the action of gravity. Discharging cylinders are respectively arranged on both sides of the discharging port at the lower part of the feeding trough to block or release the lock heads 16 in the feeding trough through the discharging cylinders. In this embodiment, a total of four discharging cylinders are provided, namely a first discharging cylinder 17, a second discharging cylinder 18, a third discharging cylinder and a fourth discharging cylinder. Among them, the first discharging cylinder 17 and the third discharging cylinder are arranged on the same side, the second discharging cylinder 18 and the fourth discharging cylinder are arranged on the same side. The cylinder push rod directions of the first discharging cylinder 17 and the third discharging cylinder are the same, and the cylinder push rod direction of the first discharging cylinder 17 is the same as the axis direction of the lock head 16. The cylinder push rod directions of the second discharging cylinder 18 and the fourth discharging cylinder are the same, and the cylinder push rod of the second discharging cylinder 18 is perpendicular to the cylinder push rod of the first discharging cylinder 17.
[0025] The structure of the feeding trough needs to be designed according to the characteristics of the structure of the lock head 16. In this embodiment, the structure of the feeding trough is as Figure 5 shown. A first connecting plate 19 is obliquely arranged at the top end of the fixed bracket 13. Two first fixing brackets 20 are fixedly installed side by side on the left wall of the first connecting plate 19 near the discharging port of the feeding trough. The cross-section of the first fixing bracket 20 is Z-shaped. The second discharging cylinder 18 and the fourth discharging cylinder are respectively installed on the two first fixing brackets 20. Second fixing brackets 21 are respectively fixedly installed at both ends on the right wall of the first connecting plate 19. The cross-section of the second fixing bracket 21 is generally a U-shaped structure with an opening towards the left. A distance is left between the first connecting plate 19 and the second fixing bracket 21. The top bottoms of the two second fixing brackets 21 are fixedly connected by a second connecting plate 22. The second connecting plate 22 and the first connecting plate 19 are opposite up and down and there is a gap between them. The middle parts of the two second fixing brackets 21 are fixedly connected by a third connecting plate 24. Two third fixing brackets are fixedly installed on the third connecting plate 24 near the discharging port of the feeding trough. The first discharging cylinder 17 and the third discharging cylinder are respectively installed on the two third fixing brackets. A limiting plate 23 with a bending structure is fixedly installed on the outer side surface of the second connecting plate 22. The feeding trough is jointly enclosed by the limiting plate 23, the second connecting plate 22, the third connecting plate 24, the second fixing bracket 21 and the first connecting plate 19.
[0026] The lock head 16 is inserted into the feed inlet end of the feed chute, so that the insertion rod 165 of the lock head 16 extends out from the open end of the feed chute. The second connecting plate 22 and the first connecting plate 19 jointly limit the limiting disc 166 of the lock head 16, and the lock seat connecting part of the lock head 16 is limited in the inner cavity enclosed by the second connecting plate 22, the third connecting plate 24 and the first connecting plate 19. Among the many lock heads 16 arranged in the feed chute, for the lock head 16 closest to the discharge port, its insertion rod 165 is limited by the push rod extended upward by the second discharging cylinder 18, and the fixing block of its lock seat connecting part is limited by the push rod extended by the first discharging cylinder 17, so that the lock head 16 will not slide down. Similarly, a lock head 16 arranged behind the lock head 16 closest to the discharge port is also jointly limited by the fourth discharging cylinder and the third discharging cylinder at the same time.
[0027] After a lock rod 3 is newly placed on the support frame 2, the control system is started to retract the push rods of the first discharging cylinder 17 and the second discharging cylinder 18 at the same time. Under the action of gravity, the lock head 16 closest to the feed chute naturally slides down and falls into the limiting seat 12 below the discharge port of the feed chute. Then, the push rod of the supporting cylinder 14 moves downward to pull the supporting seat 15 back downward, so as to make space for the assembly of the lock head 16 and the lock rod 3. Then, the control system drives the push rod 11 of the propulsion cylinder 5 to move toward the lock rod 3. The push rod 11 gradually moves the lock head 16 in the limiting seat 12 closer to the end of the lock rod 3 until the insertion rod 165 of the lock head 16 is inserted into the lock rod 3 and stops. For a lock head arranged behind the lock head 16 that has already slid down in the feed chute, due to the limitation of the third discharging cylinder and the fourth discharging cylinder, the remaining lock heads 16 arranged in the feed chute will not slide down. After the assembly of the lock head 16 and the lock rod 3 is completed once, all the above cylinders are reset. After the push rods of the first discharging cylinder 17 and the second discharging cylinder 18 are reset, the push rods of the third discharging cylinder and the fourth discharging cylinder are driven to retract, so that the arranged lock heads 16 move down one position in turn, and then the push rods of the third discharging cylinder and the fourth discharging cylinder are made to extend again, waiting for the next assembly instruction.
[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
