Description

Technical Field

[0001] This utility model relates to the field of automated assembly technology, specifically a three-angle flipping mechanism. Background Technology

[0002] In automated assembly lines, there are often scenarios where three-angle flipping is required. For example, when installing one part on another part and needing to flip one of the parts, the common method is to install the part to be flipped on the rotating part of a rotary cylinder, and then use the rotary cylinder to drive the part to flip.

[0003] However, existing rotary cylinders can typically only achieve two position angles when rotating parts that need to be flipped, namely 0° and 180°. They cannot achieve three angles of flipping. When it is necessary to flip the parts to be flipped to a 90° position, the existing rotary cylinders cannot meet the requirements, which limits their use.

[0004] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Utility Model Content

[0005] The purpose of this utility model is to provide a three-angle flipping mechanism to solve the problem mentioned in the background art that the rotary cylinder can only be used for flipping at 0° and 180° positions, but cannot achieve flipping of parts at 90° positions, which has certain limitations in use.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A three-angle flipping mechanism, comprising:

[0008] The rotary unit includes a clamping plate for clamping the parts to be flipped, and a rotary cylinder at the rear of the clamping plate for driving the clamping plate to flip.

[0009] A blocking unit, located at one end of the rotary cylinder, extends into the rotary cylinder to limit the rotation angle of the chuck.

[0010] Furthermore, the rotary unit also includes:

[0011] The mounting base is fixedly connected to the lower end of the rotary cylinder and is used to support the rotary cylinder.

[0012] The first speed control valve is located at the upper end of the rotary cylinder and on the side near the blocking unit;

[0013] The second speed control valve is located at the lower end of the rotary cylinder and on the side near the blocking unit. It is used to cooperate with the first speed control valve to supply air pressure inside the rotary cylinder.

[0014] The upper rack is slidably disposed inside the upper part of the rotary cylinder;

[0015] The lower rack is slidably disposed inside the lower part of the rotary cylinder;

[0016] The gear is rotatably located in the middle of the rotary cylinder. Its upper part meshes with the upper rack and its lower part meshes with the lower rack. Rotary shafts are fixedly connected to both sides of the gear's shaft. The rotating shafts are rotatably connected to the rotary cylinder. One end of the rotating shaft is fixedly connected to the chuck and is used to drive the chuck to rotate.

[0017] Furthermore, the rotary cylinder has a first guide groove inside and outside the upper rack for guiding the movement of the upper rack, and one end of the first guide groove is connected to the first speed control valve through the first air inlet;

[0018] The rotary cylinder has a second guide groove inside and outside the lower rack for guiding the movement of the lower rack. One end of the second guide groove is connected to the second speed control valve through the second air inlet.

[0019] The upper and lower racks are positioned in a staggered manner relative to each other.

[0020] Furthermore, a first piston is provided at one end of the upper rack located on the first speed regulating valve;

[0021] The lower rack is equipped with a second piston at one end of the second speed control valve.

[0022] Furthermore, the blocking unit includes:

[0023] A blocking cylinder is fixedly connected to one side of the rotary cylinder via an extension frame;

[0024] The third speed control valve is located at the lower end of the blocking cylinder, away from the rotary cylinder.

[0025] The fourth speed control valve is located at the lower end of the blocking cylinder near the rotary cylinder;

[0026] The limiting rod has one end slidably inserted into the blocking cylinder and the other end slidably inserted into the rotary cylinder and corresponding to the second guide groove, which is used to limit the movement of the lower rack.

[0027] Furthermore, a third piston is fixedly connected to one end of the limiting rod and inside the blocking cylinder;

[0028] The blocking cylinder has a third guide groove inside and outside the third piston for guiding the movement of the third piston.

[0029] The third speed control valve is connected to one end of the third guide groove through the fourth air inlet;

[0032] Compared with the prior art, the beneficial effects of this utility model are:

[0033] 1. This utility model secures the components to be assembled to one side of the chuck with screws. When the component needs to rotate 90° relative to its initial position, one end of the blocking unit extends forward into the rotary cylinder, causing the rotary cylinder to rotate the chuck counterclockwise to 90°, where the blocking unit blocks and limits the rotation. When the component needs to rotate 180° relative to its initial position, one end of the blocking unit retracts backward into the rotary cylinder, causing the rotary cylinder to continue rotating the chuck counterclockwise to 90°, where the blocking unit blocks and limits the rotation. When the rotary cylinder needs to switch back to the initial 0° position, it simply rotates 180° clockwise. This allows for arbitrary switching and flipping of the assembled components between 0°, 90°, and 180° positions, making it widely applicable. Attached Figure Description

[0041] 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.

[0042] Please see Figure 1-6 This utility model provides a technical solution:

[0043] A three-angle flipping mechanism, comprising:

[0044] The rotary unit 1 includes a clamping plate 15 for clamping the parts to be flipped, and a rotary cylinder 11 at the rear of the clamping plate 15 for driving the clamping plate 15 to flip.

[0045] The blocking unit 2 is located at one end of the rotary cylinder 11 and is used to extend into the rotary cylinder 11 to limit the rotation angle of the chuck 15.

[0046] It should be noted that initially, the chuck 15 is oriented away from the blocking unit 2. The parts to be assembled are fastened to one side of the chuck 15 with screws. When the parts need to rotate 90° relative to the initial position, one end of the blocking unit 2 extends forward into the rotary cylinder 11, so that when the rotary cylinder 11 drives the chuck 15 to rotate counterclockwise to 90°, it is blocked and limited by the blocking unit 2. When the parts need to rotate 180° relative to the initial position, one end of the blocking unit 2 retracts backward into the rotary cylinder 11, so that when the rotary cylinder 11 drives the chuck 15 to continue rotating counterclockwise to 90°, it is blocked and limited by the blocking unit 2. When the rotary cylinder 11 needs to switch back to the initial 0° position, the rotary cylinder 11 rotates 180° clockwise. This allows for arbitrary switching and flipping of the assembled parts between the 0°, 90°, and 180° positions, making it widely applicable.

[0047] like Figure 1-4 As shown, as an improvement, the rotary unit 1 further includes:

[0048] Mounting base 12 is fixedly connected to the lower end of the rotary cylinder 11 and is used to support the rotary cylinder 11;

[0049] The first speed control valve 13 is located on the upper end of the rotary cylinder 11 and on the side close to the blocking unit 2;

[0050] The second speed control valve 14 is located at the lower end of the rotary cylinder 11 and on the side close to the blocking unit 2, and is used to cooperate with the first speed control valve 13 to supply air pressure to the inside of the rotary cylinder 11.

[0051] The upper rack 16 is slidably disposed inside the upper part of the rotary cylinder 11;

[0052] The lower rack 18 is slidably disposed inside the lower part of the rotary cylinder 11;

[0053] Gear 17 is rotatably disposed in the middle of the rotary cylinder 11. Its upper part meshes with the upper rack 16 and its lower part meshes with the lower rack 18. Rotating shafts 171 are fixedly connected to both sides of the shaft of gear 17. The rotating shafts 171 are rotatably connected to the rotary cylinder 11. One end of the rotating shafts 171 is fixedly connected to the chuck 15 for driving the chuck 15 to rotate.

[0054] Preferably, one end of the rotary cylinder 11 is threadedly connected to an adjusting screw 19, one end of which extends into the first guide groove 113 for fine-tuning the maximum movement position of the upper rack 16.

[0055] like Figure 5-6As shown, further, the rotary cylinder 11 has a first guide groove 113 inside and outside the upper rack 16 for guiding the movement of the upper rack 16. One end of the first guide groove 113 is connected to the first speed control valve 13 through the first air inlet 111.

[0056] The rotary cylinder 11 has a second guide groove 114 inside and outside the lower rack 18 for guiding the movement of the lower rack 18. One end of the second guide groove 114 is connected to the second speed control valve 14 through the second air inlet 112.

[0057] The upper rack 16 and the lower rack 18 are positioned opposite the gear 17 in a staggered manner.

[0058] Furthermore, the upper rack 16 is provided with a first piston 161 at one end of the first speed regulating valve 13;

[0059] The lower rack 18 is provided with a second piston 181 at one end of the second speed control valve 14.

[0060] The blocking unit 2 includes:

[0061] The blocking cylinder 21 is fixedly connected to one side of the rotary cylinder 11 via the extension frame 20;

[0062] The third speed control valve 22 is located at the lower end of the blocking cylinder 21, away from the rotary cylinder 11;

[0063] The fourth speed control valve 23 is located at the lower end of the blocking cylinder 21 near the rotary cylinder 11;

[0064] The limiting rod 24 has one end slidably inserted into the blocking cylinder 21 and the other end slidably inserted into the rotary cylinder 11 and corresponds to the second guide groove 114, and is used to limit the movement of the lower rack 18.

[0065] In addition, a third piston 241 is fixedly connected to one end of the limiting rod 24 and inside the blocking cylinder 21;

[0066] The blocking cylinder 21 has a third guide groove 211 inside and outside the third piston 241 for guiding the movement of the third piston 241.

[0067] The third speed control valve 22 is connected to one end of the third guide groove 211 through the fourth air inlet 213;

[0068] The fourth speed control valve 23 is connected to one end of the third guide groove 211 opposite to the fourth air inlet 213 through the third air inlet 212; the third piston 241 is located between the third air inlet 212 and the fourth air inlet 213.

[0069] like Figure 1As shown, as an improvement, the mounting plate 15 is provided with mounting holes 151 for limiting the position of the parts.

[0070] It should be noted that: such as Figure 1-3 , Figure 5-6 As shown, in the specific implementation process of this utility model, initially, the chuck 15 points in the opposite direction to the blocking cylinder 21 and is parallel to the blocking cylinder 21. The parts to be assembled are fastened in the mounting hole 151 with screws. When the parts need to rotate 90° relative to the initial position, the fourth speed control valve 23 cuts off the air supply, and the third speed control valve 22 inputs gas into the third guide groove 211 through the fourth air inlet 213. At this time, under the thrust of the air pressure on the third piston 241, the third piston 241 drives the limiting rod 24 to extend forward in the second guide groove 114 until one end of the third piston 241 moves to the third guide groove 114. At the air inlet 212, the limit rod 24 stops moving. At this time, the first speed regulating valve 13 inputs gas into the first guide groove 113 through the first air inlet 111. Under the thrust of the air pressure in the first guide groove 113 on the first piston 161, the first piston 161 drives the gear 17 to rotate counterclockwise through the upper rack 16. The gear 17 drives the chuck 15 to rotate counterclockwise through the rotating shaft 171. At the same time, the gear 17 drives the lower rack 18 to move in the opposite direction to the upper rack 16 until one end of the lower rack 18 hits the limit rod 24 and stops moving. At this time, the chuck 15 drives the parts to rotate 90°.

[0071] like Figure 2-3 , Figure 5-6 As shown, when the component needs to rotate 180° relative to its initial position, the third speed control valve 22 cuts off the gas supply, and the fourth speed control valve 23 inputs gas into the third guide groove 211 through the third air inlet 212. At this time, under the thrust of the air pressure on the third piston 241, the third piston 241 drives the limiting rod 24 to retract backward in the second guide groove 114 until one end of the third piston 241 moves to the fourth air inlet 213, at which point the limiting rod 24 stops moving. At this time, the first speed control valve 13 continues to supply gas through the first air inlet 111. The air pressure in the first guide groove 113 pushes the first piston 161, causing the first piston 161 to continue rotating counterclockwise via the upper rack 16 and the gear 17 via the rotating shaft 171. At the same time, the gear 17 drives the lower rack 18 to move in the opposite direction to the upper rack 16 until one end of the lower rack 18 hits the limit rod 24 again and stops moving. At this time, the chuck 15 drives the parts to continue rotating counterclockwise by 90°.

[0072] like Figure 3-6As shown, when the component needs to return to its initial position, the third speed control valve 22, the fourth speed control valve 23, and the first speed control valve 13 all cut off the gas supply. The second speed control valve 14 inputs gas into the second guide groove 114 through the second air inlet 112. At this time, under the thrust of the air pressure on the second piston 181, the second piston 181 drives the gear 17 to rotate clockwise through the lower rack 18. The gear 17 drives the chuck 15 to rotate clockwise through the rotating shaft 171. At the same time, the gear 17 drives the upper rack 16 to move in the opposite direction to the lower rack 18 until one end of the upper rack 16 hits the adjusting screw 19 and stops moving. At this time, the chuck 15 returns to its initial position, thus enabling the component to be assembled to be flipped and switched at three angles, which has a wide range of applications.
