Detailed Description
The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments, and it is apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments.

when the connecting plate 5 moves towards the side wall of the box body 1, the connecting plate 5 drives the clamp 6 to shrink first and then extend into the radiating pipe 2 along the communication port 3 on the box body 1; after entering the radiating pipe 2, the connecting plate 5 moves reversely to drive the clamp 6 to expand and clamp the radiating pipe 2, and then the radiating pipe 2 is linearly retreated along the communication port 3 to be tightly attached to the outer side wall of the box body 1.

the first inclined rod 18 extends into the upper driving plate 10 to be in sliding fit with the upper driving plate 10, and the second inclined rod 19 extends into the lower driving plate 11 to be in sliding fit with the lower driving plate 11;

one end of the lower clamping jaw 13 is hinged with the lower driving plate 11, a lower limit groove is formed in the lower clamping jaw 13, a lower limit column matched with the lower limit groove is arranged on the first substrate 8, the other end of the lower clamping jaw 13 extends out to one side, far away from the second substrate 9, of the first substrate 8, and the upper clamping jaw 12 and the lower clamping jaw 13 form a splayed clamp 6.
Further, as shown in fig. 10-13, the first friction driving member 16 includes a first friction column 22, one end of the first friction column 22, which is close to the connecting rod 14, is in an inclined structure, a first telescopic hole is formed in the driving round sleeve 15, the first friction column 22 is coaxially disposed in the first telescopic hole, and the outer portion of the first friction column 22 is connected with the wall of the first telescopic hole through a first elastic member 23;

the second driving block 29 is a wedge block structure adapted to the inclined surface of the second friction column.
The first elastic member 23 and the second elastic member are springs.
The driving piece 7 is an air cylinder, an oil cylinder or an electric telescopic rod.
As shown in fig. 6 and 9, the end of the upper jaw 12 includes a driving end 24 and a clamping end 25, the clamping end 25 includes a horizontal section 26 and a protruding section 27 having a thickness greater than the horizontal section 26, and the protruding section 27 is used for clamping the inner wall of the radiating pipe 2.
The surface of the protruding section 27 is provided with a rubber layer.
Wherein, the diameter of the connecting rod 14 is smaller than that of the driving round sleeve. 2. The inclined surface of the first friction column 22 faces left, and the inclined surface of the first driving block 28 faces right; the inclined surface of the second friction column faces to the right and the inclined surface of the second driving block 29 faces to the left. 3. When the clamping jaw expands to the clamping end 25 to be horizontal, the width of the two horizontal sections 26 is slightly larger than the width of the radiating pipe 2, so that the radiating pipe 2 can compress the rubber layer to a certain extent, and the fitting degree of the clamp 6 and the radiating pipe 2 and the friction force between the clamp 6 and the radiating pipe 2 are increased (the larger the friction force is, the larger the clamping force is).
Working principle: (1) shrinkage of the jig 6: as shown in fig. 2, 5, 10 and 12, the driving member 7 is activated to move the connection plate 5 toward the left (near the side wall to be welded). When the connecting plate 5 moves, firstly (the connecting rod 14 moves relative to the driving round sleeve 15, and the second base plate 9 is kept motionless under the action of friction force between the second base plate and the frame 4) to push the first base plate 8 to move linearly;
when the first base plate 8 moves linearly, the upper driving plate 10 and the lower driving plate 11 move linearly synchronously with the first base plate 8, and meanwhile, the upper driving plate 10 moves upwards under the action of the first inclined rod 18, and the lower driving plate 11 moves downwards under the action of the second inclined rod 19.
When the upper driving plate 10 and the lower driving plate 11 do away from movement, the distance between the upper (lower) hinge point of the upper (lower) clamping jaw and the hinge point of the upper (lower) limit post is reduced, and the upper (lower) clamping jaw moves towards the direction close to the lower (upper) clamping jaw under the action of the upper (lower) limit post and the upper (lower) limit groove in the process, so that the shrinkage of the clamp 6 is realized.
(2) The clamp 6 extends: as shown in fig. 2, 5, 10 and 12, when the connecting plate 5 moves, the first driving block 28 moves toward the first friction column 22, and when the clamp 6 contracts, the first driving block 28 moves to abut against the first friction column 22. When the connecting rod 14 also has a tendency to move relative to the driving sleeve 15, the first friction column 22 is pressed, and the upward movement of the first friction column 22 increases the pressure on the first driving block 28 under the action of the spring.
At this time, the friction between the first friction column 22 and the first driving block 28 increases, and when the friction between the first friction column 22 and the first driving block 28 increases to be greater than the friction between the second substrate 9 and the frame 4, the connecting rod 14 does not move relative to the driving round sleeve 15 any more, but the connecting rod 14 pulls the driving round sleeve 15 under the action of the friction between the first friction column 22 and the first driving block 28. And the second base plate 9, the first base plate 8, the upper driving plate 10 and the lower driving plate 11 are connected to linearly move along with the connecting plate 5, so that the clamp 6 horizontally extends.
(3) And (3) expanding the clamp 6: as shown in fig. 3 and 6, after the clamps 6 are extended, both ends of the radiating pipe 2 are manually sleeved on the two clamps 6. Then the driving piece 7 is started to drive the connecting plate 5 to move reversely.
When the connecting plate 5 moves reversely, the connecting rod 14 drives the first base plate 8, the upper driving plate 10 and the lower driving plate 11 to move reversely, and the second base plate 9 is immobilized under the action of friction force between the second base plate and the frame 4 in the process. When the upper driving plate 10 and the lower driving plate 11 move reversely, the upper (lower) driving plate moves downwards (upwards) under the action of the first (second) diagonal rod, and the process clamp 6 expands (the specific principle is the same as (1), and details are omitted here.
(4) The clamp 6 linearly retreats: as shown in fig. 4, 7, 11 and 13, when the connection plate 5 moves in the reverse direction, the second driving block 29 moves toward the second friction column, and when the clamp 6 expands, the second driving block 29 moves to abut against the second friction column. When the connecting rod 14 also has a tendency to move relative to the driving sleeve 15, it presses against the second friction column, which in an upward movement increases the pressure on the second driving block 29 under the action of the spring.
At this time, the friction between the second friction column and the second driving block 29 increases, and when the friction between the second friction column and the second driving block 29 increases to be greater than the friction between the second substrate 9 and the frame 4, the connecting rod 14 does not move relative to the driving round sleeve 15 any more, but the connecting rod 14 pulls the driving round sleeve 15 under the friction between the second friction column and the second driving block 29. Further, the second base plate 9, the first base plate 8, the upper driving plate 10 and the lower driving plate 11 are connected to linearly move reversely along with the connecting plate 5, so that the clamp 6 can horizontally and linearly retract.
The clamp 6 moves the radiating pipe 2 synchronously in a horizontal linear retreating process, and when the radiating pipe 2 is tightly attached to the side wall of the transformer tank body 1, the driving piece 7 stops acting (the stopping of the driving piece 7 can be controlled by manual control but not limited to).
And (3) when the welding is finished, repeating the step (1) to enable the clamp 6 to shrink, loosening the negative pressure sucker after the clamp 6 shrinks, and enabling the clamp 6 to exit horizontally.
The arranged clamp can realize a plurality of actions such as automatic contraction, automatic extension, automatic expansion, automatic retraction and the like, so that the clamping and automatic positioning of the radiating pipe and the fixation between the radiating pipe and the transformer box body during welding can be realized; the welding process does not need to be supported manually, and the waste of human resources is avoided.
The foregoing is merely a preferred embodiment of the invention, and it is to be understood that the invention is not limited to the form disclosed herein but is not to be construed as excluding other embodiments, but is capable of numerous other combinations, modifications and environments and is capable of modifications within the scope of the inventive concept, either as taught or as a matter of routine skill or knowledge in the relevant art.
