[0029] As Figures 1-5As shown in the figure, an embodiment of the utility model provides a processing tooling for the water inlet elbow of a diesel engine, including: an upper plate 1, the upper surface of the upper plate 1 is composed of a semi-circular part and a rectangular part, the diameter of the semi-circular part is equal to the length of the rectangular part, a first arc hole 2 is penetrated through the rectangular part of the upper plate 1, a second arc hole 3 is penetrated through the semi-circular part of the upper plate 1, a sliding column 11 is slidably connected inside the first arc hole 2, a sliding block 15 is slidably connected inside the second arc hole 3, a first connecting rod 12 is fixedly installed at the lower end of the sliding column 11, a second connecting rod 14 is fixedly installed at the lower end of the sliding block 15, a lower box 4 is fixedly installed at the lower end of the upper plate 1, a servo motor 19 is fixedly installed at the upper end of the inner wall of the lower box 4, a disc 13 is fixedly installed at the output end of the servo motor 19, the side wall of the disc 13 is fixed to one end of the first connecting rod 12, one end of the second connecting rod 14 is fixed to the side wall of the disc 13, the upper end of the disc 13 is rotatably connected to the lower end of the upper plate 1, a limiting mechanism for fixing the turning end of the water inlet elbow is arranged at the upper end of the sliding column 11, clamping mechanisms for clamping both ends of the side wall of the water inlet elbow are respectively fixedly installed at the upper ends of the sliding block 15 and the upper plate 1. By starting the servo motor 19, the output end of the motor drives the disc 13 to rotate, further driving the first connecting rod 12 and the second connecting rod 14 to rotate together. At this time, the sliding column 11 and the sliding block 15 slide inside the first arc hole 2 and the second arc hole 3 respectively, adjust the clamping mechanism on the sliding block 15 to a position adapted to the other end of the elbow, stop the servo motor 19, and then press the other end of the water inlet elbow between the two groups of arc-shaped clamping plates 17 according to the above method, so that the other end of the water inlet elbow is fixed in the clamping mechanism on the sliding block 15, and both ends of the water inlet elbow can be well fixed.

[0030] As Figures 1-5As shown, in this embodiment, the limiting mechanism includes a movable plate 5, and the side wall of the movable plate 5 is penetrated by two through holes, and sliding rods 6 are slidably connected in the two through holes, and one end of the two sliding rods 6 is fixedly connected to a round cover 7, and the other end of the two sliding rods 6 is fixedly connected to a ball joint 8, and the outer walls of the two ball joints 8 are rotatably connected to elastic extrusion plates 10, and the two elastic extrusion plates 10 are symmetrically arranged about the center point of the movable plate 5. The outer walls of the two sliding rods 6 are surrounded by No. 1 springs 9, and one end of the two No. 1 springs 9 is fixed to one side of the movable plate 5, and the side walls of the two sliding rods 6 and near the ball joint 8 are fixed with connecting rings, and the two No. One end of the spring 9 is fixed to one side of the two connecting rings respectively, and the two round covers 7 are located on the other side of the movable plate 5. The two groups of elastic extrusion plates 10 rotate around the ball joint 8 respectively and fit on both sides of the water inlet elbow. At this time, since the two groups of elastic extrusion plates 10 push the two groups of slide bars 6 to slide in the through holes in the movable plate 5, the two groups of slide bars 6 move away from the elastic extrusion plates 10. At this time, the two ends of the two groups of No. 1 springs 9 are squeezed by the connecting rings on the movable plate 5 and the slide bars 6, and the two groups of No. 1 springs 9 produce compression deformation, which further pushes the two groups of elastic extrusion plates 10 to squeeze the side walls of the water inlet elbow, thereby achieving the adaptive positioning of the turning end of the water inlet elbow.

[0031] like Figures 1-5 As shown, in this embodiment, the clamping mechanism includes a movable seat 16 and two arc clamping plates 17, the outer side walls of the two arc clamping plates 17 are fixed with connecting ears, the lower ends of the two connecting ears are fixedly connected with No. 2 springs 18, the lower ends of the two No. 2 springs 18 are fixed to the upper end of the movable seat 16, the lower ends of the two arc clamping plates 17 are crossed with each other and are rotatably connected to the connecting protrusions at the upper end of the movable seat 16 through the same set of rotating rods, and one end of the water inlet elbow is fixed in the clamping mechanism on the upper plate 1, and the water inlet elbow is moved to the upper plate 1. The two groups of arc clamps 17 are pressed down. Since the distance between the upper ends of the two groups of arc clamps 17 is smaller than the diameter of the bent pipe, the two groups of arc clamps 17 first rotate toward the direction close to the connecting ears, further prompting the two groups of connecting ears to squeeze the No. 2 springs 18 downward, causing the two groups of No. 2 springs 18 to produce compression deformation. When the water inlet bent pipe enters between the two groups of arc clamps 17, the two groups of No. 2 springs 18 stretch and recover their deformation, further prompting the two groups of connecting ears and the two groups of arc clamps 17 to rotate close to each other, thereby cooperating to clamp one side of the water inlet bent pipe.

[0032] like Figures 1-5 As shown, in this embodiment, the diameter of the round cover 7 is greater than the diameter of the slide bar 6, and the round cover 7 can conveniently limit the slide bar 6 to prevent the slide bar 6 from escaping from the through hole.

[0033] like Figures 1-5 As shown, in this embodiment, the two ends of the No. 1 arc hole 2 form an angle of ninety degrees with the upper plate 1 and the center point of the semicircular portion as the center, which facilitates the sliding limit mechanism to adapt to water inlet elbows with different turning angles.

[0034] As Figures 1-5 shown, in this embodiment, the second arc hole 3 forms a 120-degree angle with the center point of the upper plate 1 and the semi-circular part, which is convenient for sliding clamping to adapt to the water inlet elbow with different turning angles.

[0035] As Figures 1-5 shown, in this embodiment, circular chamfers are provided at the surface corner positions of the two elastic pressing plates 10, which play a role in protecting the surface of the turning end of the water inlet elbow.

[0036] As Figures 1-5 shown, in this embodiment, circular chamfers are provided at the upper folding corners of the two arc clamping plates 17, which play a role in protecting the surfaces at both ends of the water inlet elbow.

[0037] For the technical solution provided by the present utility model, first, the turning end of the water inlet elbow is located at the center of the semi-circular part of the upper plate 1, and one end of the water inlet elbow is fixed in the clamping mechanism on the upper plate 1. By pressing the water inlet elbow downward into the two groups of arc clamping plates 17, since the distance between the upper ends of the two groups of arc clamping plates 17 is smaller than the diameter of the elbow, the two groups of arc clamping plates 17 first rotate towards the direction close to the connecting ears, further causing the two groups of connecting ears to squeeze the second springs 18 downward, so that the two groups of second springs 18 generate compressive deformation. When the water inlet elbow enters between the two groups of arc clamping plates 17, the two groups of second springs 18 elongate to recover the deformation, further causing the two groups of connecting ears and the two groups of arc clamping plates 17 to rotate closer to each other, thereby cooperating to clamp one side of the water inlet elbow, which is convenient for further adjusting the limiting mechanism and the other group of clamping mechanisms according to the turning angle of the elbow to fix the water inlet elbow.

[0038] Then, by starting the servo motor 19, the output end of the servo motor 19 drives the disc 13 to rotate, further driving the first connecting rod 12 and the second connecting rod 14 to rotate together. At this time, the sliding column 11 and the slider 15 slide inside the first arc hole 2 and the second arc hole 3 respectively, and the clamping mechanism on the slider 15 is adjusted to a position adapted to the other end of the elbow. Stop the servo motor 19. At this time, the other end of the water inlet elbow is pressed into the two groups of arc clamping plates 17 according to the above method, so that the other end of the water inlet elbow is fixed in the clamping mechanism on the slider 15, and the two ends of the water inlet elbow can be well fixed.

[0039] Meanwhile, when the first connecting rod 12 rotates, the moving plate 5 rotates to a position where it is convenient to position the turning end of the water inlet elbow. The two groups of elastic pressing plates 10 respectively rotate around the ball hinge 8 and fit on both sides of the water inlet elbow. At this time, since the two groups of elastic pressing plates 10 push the two groups of sliding rods 6 to slide in the through holes of the moving plate 5, the two groups of sliding rods 6 move away from the elastic pressing plates 10. At this time, the two ends of the two groups of first springs 9 are cooperatively squeezed by the connecting rings on the moving plate 5 and the sliding rods 6, and the two groups of first springs 9 generate compressive deformation, further pushing the two groups of elastic pressing plates 10 to squeeze the side wall of the water inlet elbow, achieving the adaptive positioning of the turning end of the water inlet elbow, facilitating the rapid and accurate movement of the clamping mechanism and the limiting mechanism, performing the positioning tooling on the water inlet elbow, and improving the processing accuracy of the water inlet elbow.

[0040] The present utility model covers any alternatives, modifications, equivalent methods, and solutions made within the essence and scope of the present utility model. To enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the above preferred embodiments of the present utility model. However, those skilled in the art can fully understand the present utility model without the description of these details.

[0041] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
