Description

Technical Field

[0001] The utility model relates to the technical field of main valve body processing, in particular to a 90-degree turning device. Background Art

[0002] The main valve body requires multi-faceted machining, and each surface requires a specific machining sequence based on process requirements. After machining each surface, it needs to be flipped over for subsequent steps. Previously, flipping was performed entirely manually with tooling, which was laborious. The heaviest valve bodies can weigh up to 130kg, making manual flipping difficult and posing safety risks such as slippage and injury.

[0003] In the prior art, there is a method of using a cylinder plus a connecting rod mechanism to achieve flipping, but this structure is relatively complicated. Because the load is relatively heavy, the method of using a motor and a reducer will cause impact and damage the mechanism components and the motor. Summary of the Invention

[0004] The purpose of this utility model is to provide a 90° flipping device to solve the above problems, so as to reduce the manual burden and eliminate the safety risks in manual flipping.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts, any modifications, equivalent replacements, improvements, etc., shall be included in the scope of protection of the present invention.

[0028] like Figures 1 to 5As shown, this embodiment discloses a 90° flip device for flipping heavy workpieces that are difficult to flip manually, which includes a frame 1, a 90-degree flip cylinder 2 (which together with other accessories constitutes a 90-degree flip cylinder assembly), a fixed rotating shaft 3, a bearing support frame 14, and a bearing (the fixed rotating shaft 3, the bearing support frame 14, the bearing, and other accessories constitute a bearing assembly); a loading plate 4 (which together with other accessories constitutes a flip assembly), an electrical installation plate 7, a pneumatic triplet (a drain filter, a pressure reducing valve, and an oil mist collector), a three-position five-way pneumatic solenoid valve 16 (middle-enclosed type), a knob switch 9, and a position switch 8.

[0029] The flip assembly is rotatably arranged between the 90-degree flip cylinder assembly and the bearing assembly and is located on the frame 1. It is driven to flip by the 90-degree flip cylinder 2; it includes a carrier plate 4 forming a 90-degree angle and support plates 5 arranged on both sides of the carrier plate 4; the carrier plate 4 includes a first carrier plate 401 and a second carrier plate 402, and the first carrier plate 401 and the second carrier plate 402 are fixedly connected or welded to form a 90-degree angle; the support plate 5 is arranged inside the first carrier plate 401 and the second carrier plate 401 and is fixedly connected or welded to the first carrier plate 401 and the second carrier plate 402.

[0030] The 90-degree turning cylinder assembly is fixedly installed on one side of the frame. In addition to the 90-degree turning cylinder 2, it also includes a cylinder support frame 10 and a turning connecting plate 6. The 90-degree turning cylinder 2 itself has a turning cylinder output shaft 11. The turning connecting plate 6 is detachably connected to the turning cylinder output shaft 11 of the 90-degree turning cylinder. The other end of the turning connecting plate 6 is detachably connected to the support plate 5. The 90-degree turning cylinder 2 is fixedly installed on one side of the frame 1 through the cylinder support frame 10.

[0031] The bearing assembly is fixedly arranged on the other side of the frame 1, opposite to the 90-degree flip cylinder assembly; in addition to the fixed rotating shaft 3, the bearing support frame 14, and the bearing, it also includes a bearing connecting plate 12, the bearing connecting plate 12 is fixed on the frame, the fixed rotating shaft 3 is fixed on the bearing connecting plate 12, the bearing support frame 14 swings relative to the fixed rotating shaft 3, the bearing support frame 14 is detachably connected to the support plate 5, and the fixed rotating shaft 3 is concentric with the flip cylinder output shaft 11.

[0032] The bearing assembly also includes a position switch 8 arranged on the bearing connecting plate 12 and located on both sides of the bearing support frame 14. The two position switches 8 are electrically connected to the 90-degree flip cylinder 2 so that when the bearing support frame 14 of the bearing assembly is flipped clockwise and counterclockwise, they touch each other and the power is cut off, and the 90-degree flip cylinder 2 stops outputting force.

[0033] On the side where the bearing assembly is installed, the frame 1 is also fixed with an electrical installation board 7, and the electrical installation board 7 is also provided with a knob switch 9. The knob switch 9 is electrically connected to the three-position five-way pneumatic solenoid valve 16. By controlling the opening and closing of the three-position five-way pneumatic solenoid valve 16, the flipping or stillness of the 90-degree flip cylinder 2 is controlled.

[0034] The fixed rotating shaft 3 and the 90-degree flip cylinder 2 are opposite to each other, and bearings are provided on them; the loading plate 4 is used to fix the workpiece, and is rotatably arranged between the 90-degree flip cylinder 2 and the fixed rotating shaft 3 and is located on the frame 1. It is powered by the 90-degree flip cylinder, with the bearing and the fixed rotating shaft 3 as the rotation center and support point, to achieve 90° rotation of the loading plate, thereby achieving 90° flipping of the workpiece.

[0035] The operation is achieved by rotating two knobs at the same time. The purpose of setting two knobs is to allow the operator to operate with both hands to avoid safety risks such as hand pressure during the flipping process.

[0036] To prevent the rotary cylinder from outputting force once the carrier reaches its limit position, two position switches are provided that can be triggered at these limits. When the carrier flips, the bearing support bracket 14 triggers the position switches, shutting off the air supply. This prevents the cylinder from exerting significant force even at the limit position, potentially damaging structural components. Stoppers are also provided on the carrier to prevent workpieces from slipping and falling during rapid flipping.

[0037] The 90-degree flip mechanism also includes a pneumatic control assembly connected to the 90-degree flip cylinder to control its movement. The pneumatic control assembly includes an inlet and outlet pipe, each connected to the 90-degree flip cylinder via a three-position, five-way pneumatic solenoid valve. The three-position, five-way pneumatic solenoid valve is a closed-center type. The inlet pipe is equipped with a manual drain filter, a pressure reducing valve, a pressure gauge, and an oil mist collector, in that order, at the inlet end. Flow control valves are also installed at the adapter end of the inlet and outlet pipes connected to the 90-degree flip cylinder. The three-position, five-way, closed-center type solenoid valve is also selected to avoid safety issues, such as preventing the loaded carrier from dropping suddenly if the knob is suddenly stopped or the power is lost.

[0038] The specific steps are as follows: place the object to be flipped on the sling; operate with both hands and rotate the two knobs at the same time; flip the cylinder 2 90 degrees to work; flip the loading plate; the air is automatically cut off when it reaches the limit point; and the flip is completed.
