Description
Technical Field
The utility model relates to a motor housing terminal surface friction stir welding device with cooling runner.
Background
The new energy automobile has become the trend in the future, and the most important component in the new energy automobile is exactly the motor, and the shell of the motor of new energy automobile is one of them important part again, is equipped with cooling channel in this motor shell, and the coolant liquid circuitous flows in this cooling channel thereby carries out effectual heat dissipation.
In the prior art, the cooling channel is usually formed by stretching and forming a shell with a motor mounting inner cavity, a side wall of the shell is provided with a strip of channel, but the channels are not communicated independently and mutually limited in the forming technology, so that the cooling channel cannot become a circuitous cooling channel, and to become the circuitous cooling channel, a groove needs to be milled on the end surface of the shell, every other channel on one end surface communicates two adjacent channels on the end surface through the groove, every other channel on the other end surface communicates two adjacent channels on the end surface through the groove, and the grooves on the two end surfaces are staggered mutually, so that the circuitous cooling channel can be formed. And then a filling block is filled in the milling groove to seal the end face.
The filling block is usually fixed by welding after being filled in the milling groove, and preferably by a mode which is difficult to friction weld. In the prior art, after the filling block at one end is welded, the filling block at the other end is welded, so that the welding efficiency is relatively low. At present, no device capable of welding the filling blocks at two ends simultaneously exists.
Disclosure of Invention
For not having one kind at present to carry out welded equipment to the motor housing both ends face that has the cooling runner simultaneously in view of, the utility model provides a motor housing terminal surface friction stir welding device with cooling runner can weld the motor housing both ends face that has the cooling runner simultaneously.
The technical proposal of the utility model for solving the technical problem is that: the friction stir welding device for the end face of the motor shell with the cooling flow channel comprises a base, wherein a welding assembly is arranged on the base, a friction stir welding head is arranged on the welding assembly, two welding assemblies are arranged on the base, the friction stir welding heads on the two welding assemblies are horizontally arranged, and the two friction stir welding heads are oppositely arranged.
Furthermore, the two welding assemblies are symmetrically arranged, and the two friction stir welding heads are also symmetrically arranged.
Furthermore, the welding assembly comprises a front and rear moving frame which is arranged on the base and can move back and forth, a lifting frame which is arranged on the front and rear moving frame, and a left and right moving frame which is arranged on the lifting frame, wherein the stirring friction welding head is arranged on the left and right moving frame.
The beneficial effects of the utility model reside in that: the two end faces of the motor shell with the cooling flow channel can be welded at the same time, and the working efficiency is high.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, 2 and 3, a motor housing with a cooling channel, in which the forming of the cooling channel is a more critical and harder technique, is generally performed in the prior art, as shown in fig. 3, a housing 4 with a motor mounting cavity is first formed by drawing, and a side wall of the housing 4 has a strip of channels 5, but the channels 5 are independent and not communicated with each other, and thus cannot become a circuitous cooling channel, and to become the circuitous cooling channel, it is necessary to mill grooves on an end face of the housing, and every other channel on one end face communicates two adjacent channels 5 on the end face through a milled groove, and every other channel on the other end face communicates two adjacent channels on the end face through a milled groove, and the milled grooves on the two end faces are staggered with each other, so that the circuitous cooling channel can be formed. Then, a filling block 6 is filled in the milling groove to seal the end face.
Motor shell terminal surface friction stir welding device with cooling runner, including base 1, base 1 on be equipped with welding assembly 2, welding assembly 2 on have friction stir welding head 3, base 1 on be equipped with two welding assemblies 2, the friction stir welding head 3 on two welding assemblies 2 all crouches the setting, and two friction stir welding heads 3 set up relatively. When the filling blocks on the end face of the motor shell are welded, the motor shell is placed between the two welding assemblies 2, the two end faces of the motor shell face one welding assembly respectively, then the filling blocks are filled through the two friction stir welding heads 3 on the two welding assemblies 2 respectively, and the welding efficiency is greatly improved. Preferably, the two welding assemblies 2 are symmetrically arranged, and the two friction stir welding heads 3 are also symmetrically arranged.
Of course, during welding, the friction stir welding head 3 needs to move in a track, which is the prior art and will not be described in detail again, for example, the welding assembly includes a front and rear moving frame 7 which is arranged on the base and can move back and forth, a lifting frame 8 arranged on the front and rear moving frame, and a left and right moving frame arranged on the lifting frame 8, and the friction stir welding head 3 is arranged on the left and right moving frame. The driving mechanism for driving the front and rear moving frame 7 to move forward and backward, the driving mechanism for driving the lifting frame 8 to lift, and the driving mechanism for driving the left and right moving frames to move left and right are all the prior art, for example, a screw rod mechanism, an air cylinder mechanism, a hydraulic mechanism, an electric push rod, a gear and rack mechanism, etc. can be used, and are not described herein again.
