Plant the green technology for being more appropriate to light metal alloy sheet metal assembly solid diffusivity.
Existing friction stir spot welding machine is by the pneumohydraulic pressure-cylinder on friction stir spot welding head, guide rail, gas
The parts such as dynamic brake complete Workpiece clamping action.Equipment head envelope size is big, and clamp system is complicated.
Utility model content
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：A kind of nod type friction stir spot is provided
Welding machine, including frame, walking beam, head, pneumohydraulic pressure-cylinder, tension spring, support component and control system；In the middle part of walking beam with
Frame is hinged, and head is installed on walking beam end, and head is provided with stirring tool；Pneumohydraulic pressure-cylinder two ends respectively with frame and
Walking beam is hinged, and tension spring two ends are hinged with frame and walking beam respectively；Support component is fixedly mounted in frame, is used
The workpiece that need to be welded in support；Walking beam can be between walking beam and frame the first pin joint rotate；When workpiece need to be clamped
When, control system control pneumohydraulic pressure-cylinder carries out overhanging action so that walking beam, head are rotated around the first pin joint, until machine
Stirring tool on head is contacted and compressed with workpiece surface；In clamping process, control system control pneumohydraulic pressure-cylinder is kept
Constant pressure.
Further, the frame is provided with castor close to the side on ground.
The nod type friction stir spot welding machine that the utility model is provided, using the flexible of pneumohydraulic pressure-cylinder, realizes stirring
The nod type action of friction spot welding head, realizes the clamping and release of workpiece, utilizes pneumohydraulic pressure-cylinder, friction stir spot welding machine
The coordination of head, realizes the point connection of workpiece, compared with traditional friction stir spot welding machine, equipment head envelope size is small,
Clamp system is simple in construction, safe and reliable.
Brief description of the drawings
Utility model is described further below in conjunction with the accompanying drawings：
Fig. 1 is the structure chart of the utility model nod type friction stir spot welding machine；
Fig. 2 is clamp system kinematic sketch.
Embodiment
Below in conjunction with the drawings and specific embodiments to the utility model proposes nod type friction stir spot welding machine make into one
Step is described in detail.According to following explanation and claims, advantages and features of the present utility model will become apparent from.
Referring to Fig. 1, Fig. 2, the utility model provides a kind of nod type friction stir spot welding machine, including：
Frame 1, includes the profile bar of interconnection；
2 are hinged with the frame 1 in the middle part of walking beam 2, the walking beam；
Friction stir spot welding head 3, the friction stir spot welding head 3 is installed on the end of the walking beam 2；
Pneumohydraulic pressure-cylinder 4, the two ends of pneumohydraulic pressure-cylinder 4 are hinged with the frame 1, the walking beam 2；
Tension spring 5, the two ends of tension spring 5 are hinged with the frame 1, the walking beam 2；
Support component 6, is fixed in the frame 1；
Friction stir spot welding control system 7, is electrically connected with the friction stir spot welding head 3, the pneumohydraulic pressure-cylinder 4 respectively
Connect.
It is preferred that, it is described to be provided with castor in the frame 7 of ground side in the nod type friction stir spot welding machine
11。
The course of work of the nod type friction stir spot welding machine of the present embodiment is as follows：
The first step, start, system electrification opens air valve, and start, friction stir spot welding control system 7 is started working；
Second step, place workpiece, workpiece is placed between friction stir spot welding head 3 and support component 6, workpiece back with
Thimble 61 in support component 6 is adjacent to；
3rd step, is clamped, and clicks on " clamping " button, and the control pneumohydraulic pressure-cylinder 4 of friction stir spot welding control system 7 carries out outer
Action is stretched so that walking beam 2, friction stir spot welding head 3 rotate around pin joint 12, until on friction stir spot welding head 3
Stirring tool 31 contact and compress with workpiece surface.The control pneumohydraulic pressure-cylinder 4 of friction stir spot welding control system 7 keeps permanent
Constant-pressure.
" welding " button, the control friction stir spot of friction stir spot welding control system 7 welding head 3 are clicked in 4th step, welding
Carry out welding action.
5th step, head is lifted, after the completion of welding action, and the control pneumohydraulic pressure-cylinder 4 of friction stir spot welding control system 7 is received
Contracting motion so that walking beam 2, friction stir spot welding head 3 are reversely rotated around pin joint 12, and friction stir spot welding head 3 is lifted
Rise.Take workpiece away, be that welding is prepared next time.
Obviously, those skilled in the art can carry out various changes to the utility model and deform without departing from this practicality
New spirit and scope.So, if these modifications and variations of the present utility model belong to the utility model claim and
Within the scope of its equivalent technologies, then the utility model is also intended to comprising including these changes and modification.
