Description

Technical Field

[0001] This utility model relates to the field of machining, specifically a welding device for manufacturing mechanical parts. Background Technology

[0002] Mechanical parts refer to the individual, non-separable components that make up a machine. They are the basic units of a machine, such as nuts, bolts, gears, pipes, and shafts. Mechanical parts are the basic units that constitute a machine. Through reasonable combination and connection, they can realize various functions of the machine. Welding is one of the key processes in the manufacturing of mechanical parts.

[0003] In traditional welding processes, welding tubular components usually requires operators to manually flip the components and then manually weld them. However, frequent manual operations are not only troublesome but also increase the workload of operators, reduce welding efficiency, and cause a decrease in welding accuracy due to the decline in physical strength of operators. Therefore, a welding device for manufacturing mechanical parts is proposed to solve the above problems. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] In the embodiments, by Figure 1-4The present invention discloses a welding device for manufacturing mechanical parts. The device includes a base 1, on the top of the base 1 having two support plates 2 arranged left and right. A first motor 3 is fixedly connected to the opposite sides of the two support plates 2. A protective box 4, which is rotatably connected to the output shaft of each of the two first motors 3, is fixedly connected to the outside of the output shaft of each of the two first motors 3. A clamping device 5 is provided inside the two protective boxes 4. Two clamping plates 6 are fixedly connected to the outside of the two clamping devices 5. A support frame 7 is fixedly connected to the top of the base 1. A moving device 8 is provided inside the support frame 7. A mounting plate 9 is fixedly connected to the outside of the moving device 8. A first electric push rod 10 is fixedly connected to the outside of the mounting plate 9. A welding device 11 is fixedly connected to the outside of the first electric push rod 10.

[0028] The left support plate 2 is fixedly connected to the base 1, the right support plate 2 is slidably connected to the base 1, and the top of the base 1 is fixedly connected to a second electric push rod 12 that is fixedly connected to the right support plate 2.

[0029] In this embodiment, during actual use, the second electric push rod 12 can push the right support plate 2 so that it slides relative to the base 1 to adjust the distance between the two support plates 2, so that the two welded parts are close to each other and easy to weld.

[0030] The single clamping device 5 includes a second motor 51 fixedly connected to the outside of a single protective box 4. The output shaft of the second motor 51 is fixedly connected to a left-hand screw 52 rotatably connected to the inside of the protective box 4. The left-hand screw 52 is connected to two first transmission blocks 53 by threaded transmission and fixedly connected to two clamping plates 6 respectively. The inside of the protective box 4 is fixedly connected to a limiting rod 54 that is slidably connected to the two first transmission blocks 53 respectively.

[0031] In this embodiment, during actual use, the start of the second motor 51 can drive the left and right screw 52 to rotate, and then the two first transmission blocks 53 move along the direction of the screw under the action of the screw thread. The limiting rod 54 ensures the stability of the movement direction of the two first transmission blocks 53.

[0032] The moving device 8 includes a third motor 81 fixedly connected to the outside of the support frame 7. The output shaft of the third motor 81 is fixedly connected to a threaded rod 82 rotatably connected to the inside of the support frame 7. The outside of the threaded rod 82 is connected to a second transmission block 83 fixedly connected to the mounting plate 9 via a threaded transmission.

[0033] In this embodiment, during actual use, the start of the third motor 81 can drive the threaded rod 82 to rotate, which in turn causes the second transmission block 83 to move under the action of the thread, thereby driving the mounting plate 9 and welding equipment 11 below to move.

[0034] The support frame 7 has two sliding rods 13 fixedly connected inside, and the mounting plate 9 has two sliding sleeves 14 fixedly connected to the outside, each of which is slidably connected to the two sliding rods 13.

[0035] In this embodiment, during actual use, as the mounting plate 9 moves, the outer sliding sleeve 14 will also slide along the direction of the sliding rod 13. The sliding rod 13 and the threaded rod 82 are set parallel to each other, which restricts the direction of movement and provides support for the mounting plate 9.

[0036] The interior of each of the four clamping plates 6 is arc-shaped, and each of the four clamping plates 6 is threaded with a number of bolt knobs 15. The outer sides of the bolt knobs 15 and the inner sides of the four clamping plates 6 are provided with buffer pads.

[0037] In this embodiment, during actual use, the bolt knob 15 can tighten the inside of the clamping plate 6. The bolt knob 15 is easy to disassemble and does not hinder the limiting and fixing function of the clamping plate 6 itself. Furthermore, the welded parts are stably fixed by the buffer pad and the tightening of the bolt knob 15.

[0038] Working principle:

[0039] When welding tubular welded parts, the two welded parts are first placed between two clamping plates 6, and clamped and fixed by the clamping device 5. The second motor 51 is kept away from continuous rotation to prevent its connecting lines from being pulled and tangled. Then, the welding equipment 11 under the mounting plate 9 is moved to the junction of the two welded parts by the third motor 81. The first electric push rod 10 is lowered to align its welding head with the weld seam. Then, the two first motors 3 are started at the same time to drive the welding machine to rotate slowly to weld the weld seam. Both first motors 3 are equipped with precise control modules (such as programmable logic controllers PLCs). Through the pre-written control program, synchronous and coordinated control of each motor can be achieved.
