If so arranged, the temperature-sensitive contractions are provided at the adjacent two clamping devices 200, and the two upper clamping plates 212 are fixedly connected by the connecting rod 201. Thus, when one of the upper clamping plates 212 moves up or down, the other upper clamping plate 212 can also move in the same manner by the connecting rod 201.
As shown in fig. 3 and 4: the heat transfer device 300 includes at least
The rollers 310 are positioned on two sides of the welding position of the steel 101, and a welding channel which is attached to the side wall of the welding gun 102 when the welding gun 102 passes through is reserved between the two rollers 310, so that friction is generated between the reciprocating characteristic of spot welding and the outer ring of the rollers 310 during spot welding of the steel 101, and the rollers 310 are driven to rotate; on the other hand, both sides of the roller 310 are provided with fan blades 311 and connecting rings 312, the fan blades 311 are fixedly connected with the side wall of the roller 310 in a coaxial way, and the connecting rings 312 are rotatably sleeved on the outer ring of the roller 310; in addition, the outer ring of the connecting ring 312 is communicated with a gas pipe 313;
the gas transmission cavity 320, the gas transmission cavity 320 sets up the inner circle of splint 212, and the one end intercommunication of gas transmission cavity 320 has air duct 321, and air duct 321 is fixed to be set up in the bottom of splint 212, and the venthole towards the constriction is seted up to air duct 321's lateral wall.
Meanwhile, fig. 4 shows example 1 of the temperature-sensitive shrinkage portion, as shown in the drawing: the temperature-sensitive contraction part is a main elastic member 214, the end parts of the main elastic member 214 are respectively connected with the upper clamping plate 212 and the lower clamping plate 211, the main elastic member 214 is a memory spring, and the martensite phase (i.e. phase structure at low temperature, which refers to room temperature herein) of the main elastic member 214 is a soft phase, i.e. an elongated state; the parent phase (i.e., the phase structure at high temperature, herein referred to as above room temperature) is the hard phase, i.e., the compressed state.
In combination with the above and as shown in fig. 5, the working principle of the present embodiment is as follows:
normally, the main elastic member 214 is in an elongated state, and at this time, the top end of the main elastic member 214 pushes the upper clamping plate 212 to move upwards, so that an opening for placing the steel 101 is left between the upper clamping plate 212 and the lower clamping plate 211, and at this time, the steel 101 can be directly placed on top of the lower clamping plate 211 through the opening. When welding is needed, the mechanical arm 103 drives the welding gun 102 to approach the welding position of the steel 101, in the process, the steel 101 passes through a welding channel formed between the two rollers 310, and in the first welding, the welding gun 102 moves downwards to be in contact with the welding point of the steel 101, at the moment, friction between the welding gun 102 and the rollers 310 drives the fan blades 311 to rotate, and meanwhile, the high temperature is caused around the rollers 310 in the first welding of the steel 101 by the welding gun 102. Under the action of rotation of the fan blades 311, high temperature at the roller 310 enters the air pipe 313 through the connecting ring 312, hot air in the air pipe 313 is discharged to the main elastic element 214 from the air outlet after passing through the air cavity 320 and the air guide pipe 321, and the main elastic element 214 is heated to be in a compressed state at the moment so as to pull the upper clamping plate 212 to move downwards, and the upper clamping plate 212 clamps and limits the steel 101 at the moment. The steel 101 can be pushed, so that the steel 101 rotates through the rotating wheel 213, and displacement of the steel 101 in the welding process is avoided.
It should be noted that, at the time of first welding of the steel material 101, although the steel material 101 is not in a fixed state, the steel material 101 can overcome the force generated by welding by its own weight, and therefore the steel material 101 does not displace. The main embodiment of the invention is that the phenomenon that the steel 101 is displaced and the welding position deviates from the welding gun 102 due to the rotation of the steel 101 is avoided in the welding process.
In addition, in fig. 3, a blocking cover 314 is fixedly connected to an outer ring of the air pipe 313, a connecting shaft 316 is rotatably provided on an inner wall of the blocking cover 314, a sleeve plate 315 is fixedly connected to one end of the connecting shaft 316, the sleeve plate 315 has a C-shaped structure, the sleeve plate 315 is rotatably sleeved on an outer wall of the roller 310, and a portion of the air pipe 313 in front of the roller 310 and the blocking cover 314 is made of a flexible material. When in use, the welding gun 102 penetrates between the two rollers 310, when the welding gun 102 needs to incline, the welding gun 102 can drive the rollers 310 under the action of friction force, the rollers 310 drive the sleeve plate 315, and the sleeve plate 315 drives the rollers 310 to rotate through the connecting shaft 316, so that the angle of the rollers 310 is adjusted, and the welding gun 102 with different angles can be conveniently adapted.
Moreover, in the welding process, considering that the steel 101 needs to rotate to realize the whole circle of welding, in order to improve the automation of the device, the manual labor is further reduced, as shown in fig. 6:
one end of the fan blade 311 is coaxially and fixedly connected with a transmission shaft 330, one end of the rotating wheel 213 is coaxially and fixedly connected with a driven shaft 331, and a synchronous belt 332 for synchronously rotating the transmission shaft 330 and the driven shaft 331 is sleeved between the ends of the transmission shaft and the driven shaft 331. On the other hand, in order to avoid that the driving shaft 330 cannot drive the rotating wheel 213 to move continuously in one direction due to the reciprocating rotation of the fan blades 311, in this embodiment, a ratchet assembly (not shown) is disposed between the fan blades 311 and the driving shaft 330 for transmitting the unidirectional rotation force of the fan blades 311 to the driving shaft 330. In this way, the force of the unidirectional rotation of the fan blades 311 is transmitted to the transmission shaft 330, the transmission shaft 330 drives the rotating wheel 213 to rotate through the synchronous belt 332 and the driven shaft 331, and the rotating wheel 213 can drive the steel 101 to rotate.
Therefore, the fan blades 311 can not only transmit the hot air generated by welding to the main elastic member 214 in the rotation process, but also drive the rotation of the rotation wheel 213, so that the rotation wheel 213 drives the steel 101 to automatically rotate, and the rotation force is linked with the movement of the welding gun 102, so that the steel 101 can rotate a distance during each welding of the welding gun 102, and the whole circle of welding of the steel 101 is realized.
Fig. 7 and 8 are examples 2 of the temperature-sensitive shrinkage portion, as shown in the drawings:
the temperature-sensing contraction part comprises a main elastic element 214 and a secondary elastic element 222, wherein the main elastic element 214 is positioned between the lower clamping plate 211 and the upper clamping plate 212, the top end of the secondary elastic element 222 is connected with the upper clamping plate 212, the bottom end is fixedly connected with a bottom plate 221, one end of the bottom plate 221 is fixedly connected with a movable rod 220, and the movable rod 220 longitudinally slides to penetrate through the lower clamping plate 211.
In this embodiment, the primary elastic member 214 is a normal spring, the secondary elastic member 222 is a memory spring, and the martensite phase (i.e. the phase structure at low temperature, herein referred to as room temperature) of the secondary elastic member 222 is a soft phase, i.e. an elongated state; the parent phase (i.e., the phase structure at high temperature, herein referred to as above room temperature) is the hard phase, i.e., the compressed state. Then, the air outlet hole of the sidewall of the air duct 321 is disposed toward the secondary elastic member 222.
Next, the working principle of the present embodiment is as follows:
normally, the main elastic member 214 pushes up the upper clamping plate 212 through elasticity, and an opening for placing the steel 101 is formed between the upper clamping plate 212 and the lower clamping plate 211, at this time, the steel 101 can be directly placed on top of the lower clamping plate 211 through the opening. When the steel 101 is positioned at the top of the lower clamping plate 211, the steel 101 presses the movable rod 220 to move downwards, the movable rod 220 drives the secondary elastic piece 222 to move downwards, and the secondary elastic piece 222 pulls the upper clamping plate 212 to move downwards, so that the upper clamping plate 212 is tightly attached to the steel 101;
when welding, high-temperature hot air is blown to the secondary elastic member 222 through the air outlet hole, and at this time, the secondary elastic member 222 is changed into a compressed state, so that the movable rod 220 and the upper clamping plate 212 are tensioned in the compression process, and at this time, the movable rod 220 and the upper clamping plate 212 clamp and limit the steel 101.
