Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy cast rod processing, in particular to an aluminum alloy cast rod sawing and positioning mechanism. Background Art

[0002] When processing aluminum alloy cast bars, the aluminum alloy cast bars are first placed on the rollers of the conveying device. Driven by the rollers, the aluminum alloy cast bars move forward. After the aluminum alloy cast bars hit the positioning device, they are in place by default. When adjusting the fixed length of different cast bars, it is achieved by adjusting the position of the positioning device. The positioning device adopts a flip positioning device, which flips to the running direction of the roller when interception is required. When the positioning device flips to the top of the running direction of the roller, the aluminum alloy cast bars can be released.

[0003] During actual use, when the aluminum alloy cast rod collides with the positioning device, the positioning device will move to a certain extent, causing the positioning point of the aluminum alloy cast rod to be offset, resulting in poor accuracy of the sawing length, with a tolerance range of more than 5mm.

[0030] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0031] See also Figure 1 This embodiment introduces an aluminum alloy cast rod sawing positioning mechanism, which is mainly composed of a linear slide module 1, a limit rod 2, a flip member 3 and an elastic member 4. The linear slide module 1 is installed on the side of the conveying device, does not affect the driving of the aluminum alloy cast rod by the roller, and the moving direction of the linear slide module 1 is parallel to the forward and backward direction of the aluminum alloy cast rod.

[0032] The limit rod 2 is installed on the top of the linear slide module 1. The limit rod 2 can be equipped with brackets at both ends and connected to the top of the linear slide module 1, or the end of the linear slide module 1 can be longitudinally extended to install the limit rod 2. The limit rod 2 is located directly above the screw rod of the linear slide module 1 and is parallel to it. The limit rod 2 and the movable end of the linear slide module 1 maintain a fixed longitudinal distance to provide a flipping space for the flipping member 3.

[0033] like Figure 2 As shown, the flip member 3 is mainly composed of a flip cylinder 31, a movable sleeve 32 and a support frame 33. The movable sleeve 32 and the support frame 33 serve as the movable ends of the flip member 3, and the flip cylinder 31 serves as the driving end of the flip member 3. The inner diameter of the movable sleeve 32 matches the outer diameter of the limit rod 2, so that the movable sleeve 32 is sleeved on the outer surface of the limit rod 2, and the movable sleeve 32 is located directly above the movable end of the linear slide module 1. In order to facilitate the connection of the support frame 33 to the movable sleeve 32, the middle section of the outer circumferential surface of the movable sleeve 32 is radially inwardly recessed to form an annular groove, so that the outer diameters of the two ends of the movable sleeve 32 are larger than the outer diameter of the middle part.

[0034] like Figure 3As shown, the support frame 33 includes a sleeve 331, a first bracket 332 and a second bracket 333. The sleeve 331 is sleeved in the middle of the movable sleeve 32, and the end of the sleeve 331 contacts the groove end surface of the annular groove, so that the sleeve 331 is limited in the middle of the movable sleeve 32 and can rotate but cannot move axially. The outer surface of the sleeve 331 is fixedly connected with the first bracket 332 and the second bracket 333. The first bracket 332 and the second bracket 333 are kept at a certain distance and are approximately located on both sides of the sleeve 331. The first bracket 332 is close to one end of the movable sleeve 32 and is provided with an opening adapted to the end of the movable sleeve 32. The opening of the movable sleeve 32 contacts the end of the fixed sleeve 41. In this way, when the sleeve 331 rotates, the opening of the first bracket 332 rotates in close contact with the end of the movable sleeve 32, thereby improving the stability of the rotation of the sleeve 331.

[0035] The fixed end of the flip cylinder 31 is rotatably connected to the movable end of the linear slide module 1, and the movable end is rotatably connected to the second bracket 333. When the flip cylinder 31 is extended, the second bracket 333 can drive the entire support frame 33 to flip, so that the first bracket 332 can rotate downward along the outer peripheral track of the sleeve 331, and vice versa, the first bracket 332 can be driven to rotate upward. The downward rotation of the first bracket 332 can realize that the elastic member connected thereto is located on the same horizontal line as the aluminum alloy casting rod, and the upward rotation of the first bracket 332 can realize that the elastic member is located above the aluminum alloy casting rod and is misaligned with the aluminum alloy casting rod.

[0036] In order to facilitate the observation of the rotation distance of the sleeve 331, that is, whether the first bracket 332 is rotated into place, two flip reference columns 5 are provided at the end of the movable sleeve 32 which is not in contact with the first bracket 332. The two flip reference columns 5 are distributed along the rotation direction of the first bracket 332. When the first bracket 332 contacts the flip reference column 5 located below, it indicates that the first bracket 332 has been rotated downward into place. When the first bracket 332 contacts the flip reference column 5 located above, it indicates that the first bracket 332 has been rotated upward into place.

[0037] like Figure 5As shown, the first bracket 332 is used to connect with the elastic member 4. The elastic member 4 includes a fixed sleeve 41, a first movable rod 42, a spring 43, a second movable rod 44 and a limit ring 45. The end of the first bracket 332 is fixedly connected to the fixed sleeve 41, the outer diameter of the first movable rod 42 is adapted to the inner diameter of the fixed sleeve 41, one end of the first movable rod 42 is located outside the fixed sleeve 41 and faces the aluminum alloy cast rod, and the end of the first movable rod 42 located outside the fixed sleeve 41 serves as the telescopic end of the elastic member 4, which is used to contact the aluminum alloy cast rod to intercept the aluminum alloy cast rod, the other end of the first movable rod 42 is located inside the fixed sleeve 41 and connected to the second movable rod 44, the diameter of the second movable rod 44 is smaller than the first movable rod 42, the ends of the two movable rods are fixedly connected and located on the same axis, and the other end of the second movable rod 44 is located outside the fixed sleeve 41. In order to prevent the first movable rod 42 from detaching from the fixed sleeve 41, a limiting ring 45 is fixed to one end of the fixed sleeve 41 close to the second movable rod 44, and the inner diameter of the limiting ring 45 is adapted to the second movable rod 44, so that the first movable rod 42 cannot pass through the limiting ring 45, but the second movable rod 44 can cross the limiting ring 45, and a spring 43 is arranged between the limiting ring 45 and the first movable rod 42, and the spring 43 can be sleeved on the outer surface of the second movable rod 44. In the initial state, the spring 43 pushes the first movable rod 42, so that the end of the first movable rod 42 maintains a certain distance from the end of the fixed sleeve 41. When the end of the first movable rod 42 contacts the aluminum alloy cast rod, the spring 43 is compressed, which plays a role of buffering and deceleration.

[0038] In order to facilitate observation of whether the first movable rod 42 is in contact with the aluminum alloy cast rod, the first bracket 332 is close to the fixed sleeve 41 and extends radially outward along the fixed sleeve 41 to form an extension portion, on which two telescopic reference columns 6 are arranged, and the two telescopic reference columns 6 are distributed along the telescopic direction of the second movable rod 44. When the end of the second movable rod 44 moves to the telescopic reference column 6 close to the fixed sleeve 41 or even contacts it, it means that the end of the first movable rod 42 is not in contact with the aluminum alloy cast rod. When the end of the second movable rod 44 moves to the telescopic reference column 6 far away from the fixed sleeve 41 or even contacts it, it means that the first movable rod 42 is in full contact with the aluminum alloy cast rod and has decelerated, and the linear slide module 1 can be driven to allow the elastic member 4 to drive the aluminum alloy cast rod back to the positioning point.

[0039] In order to facilitate the movable sleeve 32 to move together with the movable end of the linear slide module 1 and reduce the connection pressure of the flip cylinder 31, a reinforcing column 7 can be set between the two ends with larger diameters of the movable sleeve 32 and the movable end of the linear slide module 1 to make the movable sleeve 32 move synchronously with the movable end of the linear slide module 1, thereby realizing the horizontal movement of the elastic part 4.

[0040] In the initial state, the elastic member 4 is located a distance in front of the positioning point and is on the same horizontal plane as the aluminum alloy cast rod, that is, the elastic member 4 is located in the initial interception position. When the aluminum alloy cast rod moves forward and contacts the end of the first movable rod 42 of the elastic member 4, the spring 43 begins to be compressed until the end of the second movable rod 44 moves from one telescopic reference column 6 to another telescopic reference column 6. Then the linear slide module 1 is started to make the elastic member 4 drive the aluminum alloy cast rod back to the positioning point (that is, the positioning end position). Then the sawing device saws the aluminum alloy cast rod. The aluminum alloy cast rod that has completed the sawing can leave the positioning mechanism when the elastic member 4 rotates upward. The elastic member 4 returns to the initial interception position and continues to position and intercept the next aluminum alloy cast rod.

[0041] In this embodiment, the aluminum alloy cast rod is initially intercepted and then pushed back to the positioning point. The initial interception point is located in front of the positioning end point. The aluminum alloy cast rod can be accurately pushed to the positioning end point by pushing back, thereby avoiding the error caused by the collision between the aluminum alloy cast rod and the positioning mechanism, and achieving high precision in sawing length. The tolerance range can be controlled within 1 mm. Through the setting of the elastic part 4, the aluminum alloy cast rod can be buffered and decelerated, and then pushed back to the limited position for sawing and cutting, thereby reducing the impact force caused by the collision.

[0042] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
