Technical Field
[0001] This utility model relates to the field of single-sided welding machine technology, specifically a floating welding head for a single-sided welding machine. Background Technology
[0002] In traditional single-sided welding machines, the welding head is pushed by a cylinder to contact the surface of the object to be welded. When the welding head contacts the surface, a spring on the welding head assembly allows for a certain upward floating space. However, the spring force is difficult to adjust conveniently, making it difficult to quickly adjust the upward floating space of the traditional single-sided welding machine's floating welding head according to different welding requirements. To address this issue, a technological innovation is proposed based on the existing floating welding head for single-sided welding machines. Utility Model Content
[0003] The purpose of this invention is to provide a floating welding head for a single-sided welding machine to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a floating welding head for a single-sided welding machine, comprising:
[0005] A first pallet has two sets of pressure regulating valves evenly arranged on its left side. A second pallet is placed below the first pallet, and a support plate is provided at the bottom of the second pallet. Two sets of second sliding plates are placed on the front side of the support plate. Welding heads are provided at the bottom of the second sliding plates. A second cylinder is provided on the front side of the second sliding plates. The top of the telescopic end of the second cylinder is located at the bottom of the second pallet. The pressure regulating valves are connected to the second cylinders.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figures 1-3The single-sided welding machine's floating welding head includes a first support plate 14. Two sets of pressure regulating valves 2 are evenly fixed on the left side of the first support plate 14. A second support plate 193 is placed below the first support plate 14. A support plate 18 is fixedly installed at the bottom of the second support plate 193. Two sets of second sliding plates 192 are placed on the front side of the support plate 18. A welding head 19 is fixedly installed at the bottom of the second sliding plate 192. A second cylinder 21 is fixedly installed on the front side of the second sliding plate 192. The top of the telescopic end of the second cylinder 21 is fixedly installed at the bottom of the second support plate 193. The pressure regulating valves 2 are connected to the second cylinder 21. Two sets of linear guide rails 191 are evenly fixed on the front side of the plate 18. A guide groove is opened on the rear side of the second slide plate 192. The guide groove passes through the top of the second slide plate 192. The linear guide rails 191 are slidably arranged in the guide groove. Each welding head 19 corresponds to a pressure regulating valve 2 and a second cylinder 21. The pressure value of the second cylinder 21 is controlled by the pressure regulating valve 2 to achieve the pressure protection required during welding. When welding head 19 is pressed, if the pressure is greater than the thrust of the second cylinder 21, the second cylinder will be squeezed and compressed to achieve buffering of welding head 19.
[0019] A motor 15 is fixedly installed on the top of the first support plate 14. A through hole is opened through the top of the first support plate 14. The output end of the motor 15 passes through the through hole of the first support plate 14 and is connected to a rotating shaft 17. A bearing seat 16 is sleeved on the outer ring of the rotating shaft 17. The rotating shaft 17 is supported to rotate by the bearing seat 16. The second support plate 193 is fixedly installed at the bottom of the rotating shaft 17. The rotating shaft 17 is driven to rotate by the motor 15, and the second support plate 193 is driven to rotate by the rotating shaft 17, thereby driving the welding head 19 located below the second support plate 193 to rotate.
[0020] A first slide plate 13 is fixedly installed on the right side of the first support plate 14 and the bearing seat 16. A concave seat 12 is fixedly installed on the right side of the first slide plate 13. An mounting plate 1 is placed on the outer side of the concave seat 12. A groove is opened through the front side of the mounting plate 1. The side of the concave seat 12 away from the first slide plate 13 is placed in the groove. A first cylinder 11 is fixedly installed on the top of the mounting plate 1. The telescopic end of the first cylinder 11 passes through the top of the mounting plate 1 and connects to the top of the part of the concave seat 12 located in the groove. The first cylinder 11 drives the concave seat 12 to move downward. The concave seat 12 drives the first slide plate 13 to move downward. This drives the welding head 19 located on the outer side of the first slide plate 13 to move downward. This drives the welding head 19 to contact the object to be welded for welding.
[0021] Working principle: The motor 15 drives the rotating shaft 17 to rotate, which in turn drives the second support plate 193 to rotate. This causes the welding head 19 located below the second support plate 193 to rotate. The first cylinder 11 drives the concave seat 12 to move downward, which in turn drives the first slide plate 13 to move downward. This causes the welding head 19 located outside the first slide plate 13 to move downward, thus bringing the welding head 19 into contact with the object to be welded for welding. Each welding head 19 corresponds to a pressure regulating valve 2 and a second cylinder 21. The pressure regulating valve 2 controls the pressure value of the second cylinder 21 to achieve the pressure protection required during welding. When the welding head 19 is under pressure, if the pressure is greater than the thrust of the second cylinder 21, the second cylinder will be compressed to buffer the welding head 19. The second slide plate 192 is guided linearly with high precision by the linear guide rail 191.
