[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 5 This utility model provides a technical solution: an ear plate welding and installation fixture, including a magnet 1, a lifting assembly at the top of the magnet 1, a frame 2 at the top of the lifting assembly, an adjusting assembly inside the frame 2, two connecting rods 3 on the adjusting assembly, a fixed plate 9 at the bottom of each connecting rod 3, a sliding assembly on each fixed plate 9, and a fixed clamping plate 10 at the bottom of each connecting rod 3. A movable clamping plate 14 is rotatably connected to the sliding assembly near the fixed clamping plate 10 via a bearing. The device is attracted to the bucket by the magnet 1, and the two ear plates are placed in the welding position. The lifting assembly moves the frame 2, adjusting assembly, connecting rods 3, fixed clamping plate 10, and movable clamping plate 14 together. The movable clamping plate 14 and the sliding assembly slide downwards. By adjusting the settings of the assembly, the positions of the fixed clamping plate 10 and the movable clamping plate 14 can be adjusted so that the fixed clamping plate 10 and the movable clamping plate 14 are located on both sides of the ear plate, and the fixed clamping plate 10 is in close contact with one side of the ear plate. The movable clamping plate 14 is driven by the sliding assembly to slide towards the fixed clamping plate 10 and cooperate with the fixed clamping plate 10 to clamp and fix the ear plate, thereby fixing the ear plate and avoiding the need for manual support during welding. This solves the problem that after the ear plate is placed in the welding position, it is necessary to manually support it to prevent it from moving during the welding process, which would cause deviation in its position and angle and affect its normal connection with the excavator.

[0022] In this embodiment, the top end of the movable clamping plate 14 and the bottom end of the connecting rod 3 are both flat and tightly fitted, which can prevent the movable clamping plate 14 from rotating with the screw 12 when the screw 12 rotates.

[0023] In this embodiment, the sliding assembly includes a threaded cylinder 11, a screw 12, and a handle 13. The threaded cylinder 11 is fixedly inserted into the middle of the fixed plate 9, and the screw 12 is screwed into the inner cavity of the threaded cylinder 11. The handle 13 is located at the end of the screw 12 away from the fixed clamping plate 10. The end of the screw 12 close to the fixed clamping plate 10 is rotatably connected to the movable clamping plate 14 through a bearing. Rotating the handle 13 causes the handle 13 to drive the screw 12 to rotate. Since the screw 12 is screwed into the inner cavity of the threaded cylinder 11, when the screw 12 rotates, the screw 12 can slide along the axial direction of the threaded cylinder 11, thereby causing the movable clamping plate 14 to slide towards the fixed clamping plate 10 to clamp and fix the ear plate.

[0024] In this embodiment, the lifting assembly includes a motor 15, a lead screw 16, a moving cylinder 17, a fixed cylinder 18, a slide rod 19, and a connecting assembly. The motor 15 is located at the top of the magnet 1. The lead screw 16 is fixedly connected to the output end of the motor 15. The moving cylinder 17 is screwed onto the outer wall of the lead screw 16 and fixedly connected to the bottom end of the frame 2. The fixed cylinder 18 is located at the top of the magnet 1. The slide rod 19 is slidably inserted into the inner cavity of the fixed cylinder 18 and fixedly connected to the bottom end of the frame 2. The connecting assembly is located in the inner cavity of the fixed cylinder 18 and fixedly connected to the outer wall of the slide rod 19. Next, start the motor 15, which drives the lead screw 16 to rotate. Under the rotational force of the thread on the outer wall of the lead screw 16, when the lead screw 16 rotates, the moving cylinder 17 can drive the frame 2, the fixed clamping plate 10, the moving clamping plate 14 and the sliding assembly to slide up and down in a straight line under the limiting action of the fixed cylinder 18 and the slide rod 19, thereby realizing the height adjustment of the fixed clamping plate 10, so that the fixed clamping plate 10 and the moving clamping plate 14 are located on both sides of the ear plate, which makes it convenient to adjust the height of the fixed clamping plate 10 and the moving clamping plate 14 according to the ear plate of different heights.

[0025] In this embodiment, the connecting component includes a sliding groove 20 and a sliding block 21. The sliding groove 20 is formed on the inner wall of the fixed cylinder 18. The sliding block 21 is slidably embedded in the inner cavity of the sliding groove 20 and fixedly connected to the outer wall of the sliding rod 19. Under the action of the sliding groove 20 and the sliding block 21, one end of the sliding rod 19 can always be inserted into the inner cavity of the fixed cylinder 18, which improves the stability of the lifting component during use. The inner cavity of the sliding groove 20 and the outer wall of the sliding block 21 are adapted to each other and are both dovetail-shaped, which can keep one end of the sliding block 21 embedded in the inner cavity of the sliding groove 20, which improves the stability of the connecting component during use.

[0026] In this embodiment, the adjustment assembly includes a lead screw 4, a knob 5, a slider 6, and a limiting assembly. One end of the lead screw 4 is rotatably connected to the left side of the inner cavity of the frame 2 via a bearing, and the other end of the lead screw 4 extends to the right end of the frame 2 and is fixedly connected to the knob 5. Two sliders 6 are respectively screwed to the left and right sides of the outer wall of the lead screw 4 and are respectively fixedly connected to the two connecting rods 3. The limiting assembly is located at the bottom of the inner cavity of the frame 2 and is fixedly connected to the two sliders 6. Rotating the knob 5 causes the lead screw 4 to rotate, thereby generating a relative thread rotation force on the opposite threads on the left and right sides of the outer wall of the lead screw 4. This causes the two sliders 6 to slide relative to each other under the limiting action of the limiting groove 7 and the limiting block 8. This causes the two connecting rods 3 to drive the two fixed clamping plates 10, the movable clamping plate 14, and the sliding assembly to slide relative to each other. This allows for convenient adjustment of the positions of the fixed clamping plates 10 and the movable clamping plates 14 according to the distance between the two ear plates, so that one side of the fixed clamping plate 10 is in close contact with one side of the outer wall of the ear plate.

[0027] In this embodiment, the threads on the left and right sides of the outer wall of the lead screw 4 are arranged opposite to each other, so that when the lead screw 4 rotates, the left and right sides of its outer wall generate relative thread rotation force, so that the two sliders 6 slide relative to each other simultaneously under the limiting action of the limiting groove 7 and the limiting block 8.

[0028] In this embodiment, the limiting component includes a limiting groove 7 and limiting blocks 8. The limiting groove 7 is formed at the bottom of the inner cavity of the frame 2. Both limiting blocks 8 are slidably embedded in the inner cavity of the limiting groove 7 and are respectively fixedly connected to the bottom ends of the two sliders 6. Under the joint action of the limiting groove 7 and the limiting blocks 8, the sliders 6 are prevented from rotating with the lead screw 4 when the lead screw 4 rotates, thus improving the stability of the sliding component during use. The inner cavity of the limiting groove 7 and the outer wall of the limiting block 8 are adapted to each other and are both in the shape of a "T", which can keep one end of the limiting block 8 embedded in the inner cavity of the limiting groove 7, thus improving the stability of the limiting component during use.
