Description

A welding device for annular tracks

Technical Field

The invention relates to the field of welding, in particular to a welding device for an annular track.

Background technique

Ring welding machine refers to a machine equipment that is used for welding annular gaps. For example, the welds between the upper and lower covers and the shell of a household air conditioner compressor are welded by a ring welding machine. Ring welding machines are divided into vertical ring welding machines and horizontal ring welding machines. The welding machine generally used for ring welding is a gas shielded welding machine with automatic wire feeding.

The existing ring welding machine rotates the material to enable a fixed welding gun to weld the material. However, when the ring weld to be welded is wavy, simply rotating the material cannot keep the welding gun and the weld corresponding, which will result in the wavy ring weld being unable to be welded. In addition, the welding angle of the welding head of the existing ring welding machine cannot be adjusted. When the welding surface is inclined, the welding blocks on both sides of the weld cannot remain symmetrical, which will affect the stability of the welding.

As shown in FIGS. 1 to 7 , a welding device for an annular track according to the present invention comprises a column 1, a flip assembly 2 is arranged on the column 1, a welding assembly 3 is arranged on one side of the flip assembly 2, a rotating assembly 4 is arranged on the surface of the column 1, and a clamping assembly 5 is arranged on the surface of the flip assembly 2;

The flip assembly 2 includes a semicircular ball 21, which is fixedly connected to the upper end of the column 1. The semicircular ball 21 is clamped in the semicircular groove 22. The semicircular groove 22 is arranged at the center of the lower surface of the support plate 23. The lower end of the column 1 is fixedly connected to a bottom plate 24. A groove 25 is arranged on the lower surface of the support plate 23. Two slide grooves 26 are symmetrically arranged on the inner wall of the groove 25. The same push block 27 is slidably connected inside the two slide grooves 26. A third cylinder 28 is fixedly connected to the lower surface of the push block 27. The third cylinder 28 is controlled to extend and retract according to the position of the weld. When the third cylinder 28 extends and retracts, it drives the push block 27 to slide in the slide groove 26. The inclined slide groove 26 is pushed by the push block 27 to drive the support plate 23 to flip, thereby driving the change in the position of the material in contact with the welding head 38. The welding head 38 is always corresponding to the weld through the cooperation of the second cylinder 37, so that the welding machine can weld the wavy weld.

Specifically, the welding assembly 3 includes a first cylinder 31, which is embedded in one end of the bottom plate 24, and the output end of the first cylinder 31 is fixedly connected to a fixing plate 32, and the upper end of the fixing plate 32 is fixedly connected to an arc plate 33, and a clamping groove 34 is provided on the surface of the arc plate 33, and the clamping groove 34 is clamped with a ring clamping groove 35, and the ring clamping groove 35 is provided on the outer wall of a fixing sleeve 36, and a second cylinder 37 is embedded in the fixing sleeve 36, and a welding head 38 is fixedly connected to the output end of the second cylinder 37, and an annular seat 39 is fixedly sleeved on the outer wall of the second cylinder 37. A spring 310 is fixedly connected to one side of the annular seat 39, and a U-shaped rubber sleeve 311 is fixedly connected to the other end of the spring 310. The U-shaped rubber sleeve 311 is pulled away from the surface of the arc plate 33, and then the fixed sleeve 36 is pushed to slide in the clamping groove 34. The fixed sleeve 36 drives the second cylinder 37 to slide in the clamping groove 34. When the second cylinder 37 drives the welding head 38 to move to a suitable angle, the U-shaped rubber sleeve 311 is released, and the U-shaped rubber sleeve 311 is pushed to fit the outer wall of the arc plate 33 by the spring 310, thereby fixing the position of the second cylinder 37.

Specifically, the rotating assembly 4 includes a first bearing 41, which is fixedly sleeved on the outer wall of the column 1. A rotating plate 42 is fixedly sleeved on the outer wall of the first bearing 41. A first motor 43 is fixedly connected to the upper surface of the rotating plate 42. A gear 44 is fixedly connected to the output end of the first motor 43. The gear 44 is meshed with a gear ring 45. The gear ring 45 is fixedly sleeved on the outer wall of the column 1. The first motor 43 is started to drive the gear 44 to rotate. When the gear 44 rotates, it rotates around the column 1 by utilizing the reverse thrust of the gear ring 45. The gear 44 drives the rotating plate 42 to rotate around the column 1. When the rotating plate 42 rotates, it drives the third cylinder 28 to rotate. The third cylinder 28 drives the push block 27 to push the groove 25 to drive the support plate 23 to rotate. The support plate 23 drives the material to rotate so that the welding head 38 moves on the weld on the surface of the material.

Specifically, the clamping assembly 5 includes four fixed blocks 51, which are symmetrically fixedly connected to the lower surface of the support plate 23. The two fixed blocks 51 on both sides are fixedly connected with a second motor 52. The output ends of the two second motors 52 are fixedly connected with threaded rods 53. Both ends of the two threaded rods 53 are rotatably connected to the surfaces of the two fixed blocks 51 through second bearings 54. The two threaded rods 53 are threadedly connected inside two threaded holes 55. The two threaded holes 55 are opened inside two slide bars 56. The two slide bars 56 are slidably connected inside two moving grooves 57. The material is placed on the upper surface of the support plate 23, and then the second motor 52 is started to drive the two threaded rods 53 to rotate. When the two threaded rods 53 rotate, they push the inner walls of the two threaded holes 55, and drive the slide bars 56 to move through the threaded holes 55. The two slide bars 56 drive the two triangular clamping blocks 58 to symmetrically clamp on both sides of the material, thereby fixing the material.

Specifically, the slide groove 26 is tilted inside the groove 25 , and the inner wall of the slide groove 26 matches the surface of the push block 27 . The tilted slide groove 26 causes the support plate 23 to flip when the push block 27 pushes.

Specifically, the distance between the inner walls of the ring clamping groove 35 on both sides is the same as the distance between the inner walls of the clamping groove 34 , so that the fixing sleeve 36 can be stably clamped in the clamping groove 34 through the ring clamping groove 35 .

Specifically, the U-shaped rubber sleeve 311 is slidably sleeved on the surface of the second cylinder 37, and both ends of the U-shaped rubber sleeve 311 are in contact with the outer wall of the arc plate 33. The U-shaped rubber sleeve 311 squeezes the arc plate 33 to conveniently fix the second cylinder 37 on the arc plate 33.

Specifically, the upper ends of the two slide bars 56 extend out of the moving groove 57 , and the side walls of the two slide bars 56 that are close to each other are fixedly connected with triangular clamping blocks 58 , so that the materials can be clamped by the triangular clamping blocks 58 on the slide bars 56 .

When in use, first place the material on the upper surface of the support plate 23, then start the second motor 52 to drive the two threaded rods 53 to rotate, and when the two threaded rods 53 rotate, they push the inner walls of the two threaded holes 55, and drive the slide bars 56 to move through the threaded holes 55, and the two slide bars 56 drive the two triangular clamping blocks 58 to symmetrically clamp the two sides of the material, so that the material is fixed, and then pull the U-shaped rubber sleeve 311 to detach from the surface of the arc plate 33, and then push the fixed sleeve 36 to slide in the clamping groove 34, and the fixed sleeve 36 drives the second cylinder 37 to slide in the clamping groove 34. When the second cylinder 37 drives the welding head 38 to move to a suitable angle, the U-shaped rubber sleeve 311 is released, and the U-shaped rubber sleeve 311 is pushed to fit the outer wall of the arc plate 33 by the spring 310, so that the position of the second cylinder 37 is fixed, and by changing the fixed angle of the second cylinder 37, the angle between the welding head 38 and the welding surface can be changed. The welding angle is adjusted to keep the welding solder at a high stability, and then the first motor 43 is started to drive the gear 44 to rotate. When the gear 44 rotates, the reverse thrust of the gear ring 45 is used to rotate around the column 1. The gear 44 drives the rotating plate 42 to rotate around the column 1. When the rotating plate 42 rotates, it drives the third cylinder 28 to rotate. The third cylinder 28 drives the push block 27 to push the groove 25 to drive the support plate 23 to rotate. The support plate 23 drives the material to rotate so that the welding head 38 moves on the weld on the surface of the material. At the same time, according to the position of the weld, the third cylinder 28 is controlled to extend and retract. When the third cylinder 28 extends and retracts, it drives the push block 27 to slide in the slide 26. The inclined slide 26 is pushed by the push block 27 to drive the support plate 23 to flip, thereby driving the change in the contact position between the material and the welding head 38. Through the cooperation of the second cylinder 37, the welding head 38 is always corresponding to the weld, so that the welding machine can weld the wavy weld.
