Description

Technical Field

[0001] The utility model relates to the technical field of valve production, in particular to a welding flipping device for valve production. Background Art

[0002] Valves are control components in fluid delivery systems, with functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems come in a wide variety of varieties and specifications, from the simplest shutoff valves to the various valves used in extremely complex automatic control systems.

[0003] During the valve production process, welding operations need to be performed on the valve. In the existing valve production process, welding is mostly performed manually using a spray gun. Since the valve temperature increases during the welding process, the staff needs to wear protective gloves to turn the valve over, and then take off the gloves to weld with a welding gun. The gloves need to be put on and taken off many times during the welding process, which undoubtedly increases the welding time and affects the valve production efficiency. Therefore, a welding flipping device for valve production is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In the embodiment, Figure 1-4 A welding flip device for valve production is provided, comprising two bases 1, the inner sides of the two bases 1 are fixedly connected with guide columns 2, the top ends of the two guide columns 2 are fixedly connected with the connecting plate 3, the outer sides of the two guide columns 2 are slidably connected with column sleeves 4, the outer sides of the two column sleeves 4 are fixedly connected with the inner sides of the mounting seats 5, the mounting seats 5 are provided with a rotating assembly 6, the rotating assembly 6 is provided with a clamping assembly 7 for fixing the valve, and the connecting plate 3 is provided with an up-and-down moving assembly 8 for moving the mounting seat 5 up and down;

[0023] The rotating assembly 6 includes a guide rail 61, a slider 62, a rack 63, a cylinder 64, a cylinder push rod 65, a connecting piece 66, a limit seat 67, a rotating seat 68, a rotating shaft 69 and a gear 610. The top of the mounting seat 5 is fixedly connected with the guide rail 61, the top of the guide rail 61 is slidably connected with the slider 62, the top of the slider 62 is fixedly connected with the rack 63, the mounting seat 5 is fixedly connected with the cylinder 64, the inner side of the cylinder 64 is slidably connected with the cylinder push rod 65, the left end of the cylinder push rod 65 is fixedly connected with the connecting piece 66, and the connecting piece 66 is fixedly connected to the right end of the slider 62, the top of the mounting seat 5 is fixedly connected with the limit seat 67, the top of the mounting seat 5 is fixedly connected with two rotating seats 68, the inner sides of the two rotating seats 68 are both rotatably connected with the rotating shaft 69, and the outer side of the rotating shaft 69 is fixedly connected with a gear 610 meshing with the rack 63;

[0024] The clamping assembly 7 includes a mounting plate 71, a clamping cylinder 72, a lower clamping jaw 73 and an upper clamping jaw 74. The outer side of the rotating shaft 69 is fixedly connected to the mounting plate 71, the rear end of the mounting plate 71 is fixedly connected to the clamping cylinder 72, the bottom end of the clamping cylinder 72 is fixedly connected to the lower clamping jaw 73, and the output end of the clamping cylinder 72 is fixedly connected to the upper clamping jaw 74.

[0025] With the above arrangement, the valve is first placed between the lower clamping jaw 73 and the upper clamping jaw 74, the clamping cylinder 72 is started, and the upper clamping jaw 74 gradually moves downward until the lower clamping jaw 73 and the upper clamping jaw 74 clamp the valve and fix it, and the position of the valve is adjusted by the up and down moving component 8 (when using the up and down moving component 8, the two column sleeves 4 will slide along the outer sides of the two guide columns 2, thereby changing the height of the mounting seat 5, and finally changing the height of the valve), and the valve is welded using a welding mechanism. If the valve needs to be flipped during the welding process, it is only necessary to start the cylinder 64, the cylinder push rod 65 is pushed out, the connecting piece 66 moves to the left, the slider 62 slides to the left along the top of the guide rail 61, and then the rack 63 moves to the left. Since the rack 63 and the gear 610 are meshed with each other, the gear 610 rotates, thereby rotating the shaft 69, and then flipping the valve, and the limit seat 67 plays a limiting role to prevent the slider 62 from moving too much and leaving the guide rail 61.

[0026] Reference Figure 1-4 , wherein the up-and-down moving assembly 8 comprises a threaded sleeve 81, a threaded rod 82 and a hand wheel 83, the threaded sleeve 81 is fixedly connected to the connecting plate 3, the inner side of the threaded sleeve 81 is threadedly connected to the threaded rod 82, the top end of the threaded rod 82 is fixedly connected to the hand wheel 83, and the threaded rod 82 is rotatably connected to the inner side of the mounting seat 5;

[0027] With the above-mentioned structural arrangement, by holding the hand wheel 83 and turning it, the threaded rod 82 will rotate and move downward along the center line direction of the threaded sleeve 81, thereby causing the mounting seat 5 to move downward, and by reversing the hand wheel 83, the threaded rod 82 will rotate and move upward and reset along the center line direction of the threaded sleeve 81, thereby causing the mounting seat 5 to move upward and reset. It should be noted that the threaded rod 82 is rotatably connected to the inner side of the mounting seat 5 and is limited to the inner side of the mounting seat 5 and cannot produce vertical displacement, so the threaded rod 82 will not separate from the inner side of the mounting seat 5.
