Description

Technical Field

[0001] This utility model relates to an automatic flipping milling device for aluminum cover plates, belonging to the field of metal processing technology. Background Technology

[0002] In the processing of aluminum cover plates, milling and turning operations are often required on both sides. Traditional methods involve manually disassembling, flipping, and re-clamping the aluminum cover plate after machining one side, which has many drawbacks. Firstly, manual operation consumes a significant amount of time and manpower, resulting in extremely low production efficiency. Secondly, manual clamping and positioning makes it difficult to guarantee accuracy each time, leading to difficulty in controlling machining precision, increased scrap rates, and higher production costs. Existing processing methods can no longer meet the demands, necessitating an urgent device that can automatically flip and efficiently perform milling and turning operations. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide an automatic flipping milling device for aluminum cover plates.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an automatic flipping milling device for aluminum cover plates, comprising a base, a left side plate, a right side plate, a fixture, a rotating shaft, bearings, and a drive mechanism. The left side plate and the right side plate are vertically connected to both ends of the base. The fixture holds a workpiece, and a rotating shaft is fixedly connected to both ends of the fixture. A pair of rotating shafts are coaxially arranged and rotatably connected to the left side plate and the right side plate respectively through bearings. The drive mechanism is connected to the right side plate and drives the rotating shaft to rotate. A baffle is fixedly connected to the side of the left side plate, and a rotating arm is connected to the end of the rotating shaft rotating on the left side plate. The rotating arm is perpendicularly connected to the rotating shaft. After the rotating arm rotates, it is blocked by the baffle, which restricts the rotating arm to rotate within a 180-degree range.

[0005] The present invention is further configured such that: a cover plate is connected to the baffle, and a plurality of pairs of insertion holes are provided on the cover plate and the left side plate, and a plug rod is inserted between a pair of insertion holes; the rotating arm is locked between the left side plate, the baffle, the cover plate and the plug rod.

[0006] A further feature of this invention is that the insertion rod is wedge-shaped.

[0007] The present invention is further configured such that: there are two pairs of insertion holes, which are respectively located on the sides of the starting and ending positions of the rotating arm; there are two insertion rods, and a pair of insertion rods are fixedly connected by a connecting rod.

[0008] The present invention is further configured such that: the driving mechanism includes a housing, a motor, a first gear, and a second gear; the housing is fixedly connected to the right side plate; the motor is fixedly connected to the outside of the housing; the output shaft of the motor extends into the housing and is fixedly connected to the first gear; the first gear meshes with the second gear; and the second gear is fixedly connected to the rotating shaft on the right side plate; the diameter of the second gear is three times the diameter of the first gear.

[0009] The present invention is further configured as follows: the clamp includes several jaws, a rack, a disc, a central tube, a retaining spring, and a turntable. The jaws are arranged in a circular array. A rack is provided at the lower end of the jaws. A central hole is provided in the middle of the disc, and several sliding grooves are provided radially. The sides of the jaws are slidably connected in the sliding grooves. The lower surface of the disc is fixedly connected to the top of the central tube. The turntable is sleeved on the central tube and has a threaded groove that meshes with the rack. The retaining spring is connected to the lower end of the central tube and abuts against the turntable.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The drive mechanism drives the rotating shaft and fixture to rotate, causing the workpiece to flip. The rotating arm connected to the rotating shaft is blocked by a baffle after rotation, limiting the rotation of the rotating arm within a certain range. This allows for the machining of the top and bottom surfaces of the workpiece. There is no need to remove the workpiece from the fixture and re-clamp it, reducing the time spent on manual operation. Furthermore, since the workpiece center remains consistent after rotation, there is no need for repositioning, and the center of the machining tool remains unchanged, maintaining the stability of the machining process.

[0013] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0014] See appendix Figure 1-5 As shown, an automatic flipping milling device for aluminum cover plates in this embodiment includes a base 1, a left side plate 2, a right side plate 3, a clamp 4, a rotating shaft 5, a bearing 6, and a drive mechanism 7. The left side plate 2 and the right side plate 3 are vertically connected to both ends of the base 1. The clamp 4 holds a workpiece 8, and a rotating shaft 5 is fixedly connected to both ends of the clamp 4. The pair of rotating shafts 5 are coaxially arranged and rotatably connected to the left side plate 2 and the right side plate 3 through the bearing 6, respectively. The drive mechanism 7 is connected to the right side plate 3 and drives the rotating shaft 5 to rotate. A baffle 9 is fixedly connected to the side of the left side plate 2. A rotating arm 10 is connected to the end of the rotating shaft 5 that rotates on the left side plate 2. The rotating arm 10 is perpendicularly connected to the rotating shaft 5. After the rotating arm 10 rotates, it is blocked by the baffle 9, which restricts the rotating arm 10 from rotating within a 180-degree range.

[0015] The drive mechanism 7 drives the rotating shaft 5 and the fixture 4 to rotate, causing the workpiece 8 to flip. The rotating arm 10, connected to the rotating shaft 5, is blocked by the baffle 9 after rotation, limiting its rotation within a 180-degree range. This allows for machining of the top and bottom surfaces of the workpiece. There is no need to remove the workpiece 8 from the fixture 4 and re-clamp it, reducing the time spent on manual operation. Furthermore, since the workpiece center remains consistent after rotation, there is no need for repositioning, and the center of the machining tool remains unchanged, maintaining the stability of the machining process. In this patent application, the workpiece is an aluminum cover plate, a cylindrical workpiece.

[0016] In order to maintain stability during the processing of workpiece 8, the present invention is further configured as follows: a cover plate 11 is connected to the baffle 9, and a plurality of pairs of insertion holes 12 are provided on the cover plate 11 and the left side plate 2, and an insertion rod 14 is inserted between a pair of insertion holes 12; the rotating arm 10 is locked between the left side plate 2, the baffle 9, the cover plate 11 and the insertion rod 14.

[0017] To facilitate the gradual locking of the rotating arm 10 and reduce the gap between the rotating arm 10 and the insertion rod 14, the present invention is further configured such that the insertion rod 14 is wedge-shaped. As the insertion rod 14 is inserted into the insertion hole 12, the gap between the insertion rod 14 and the rotating arm 10 gradually decreases until the rotating arm 10 and the insertion rod 14 are in close contact, firmly locking the rotating arm 10.

[0018] For ease of operation, this utility model is further configured as follows: there are two pairs of insertion holes 12, respectively located on the sides of the starting and ending positions of the rotating arm 10; there are two insertion rods 14, with a pair of insertion rods 14 fixedly connected by a connecting rod 13. By pulling the connecting rod 13, a pair of insertion rods 14 can be simultaneously pulled out of the insertion holes 12, making operation more convenient.

[0019] The drive mechanism 7 includes a housing 71, a motor 72, a first gear 73, and a second gear 74. The housing 71 is fixedly connected to the right side plate 3. The motor 72 is fixedly connected to the outside of the housing 71. The output shaft of the motor 72 extends into the housing 71. The first gear 73 is fixedly connected to the output shaft of the motor 72. The first gear 73 meshes with the second gear 74. The second gear 74 is fixedly connected to the rotating shaft 5 on the right side plate 3. The diameter of the second gear 74 is three times the diameter of the right side plate of the first gear 73.

[0020] The motor 72 is started, driving the first gear 73 and the second gear 74 to rotate. The second gear 74 drives the rotating shaft 5 and the clamp 4 to rotate. Since the diameter of the second gear 74 is three times that of the first gear 73, the rotational speed is reduced and the torque is increased, making the rotation of the clamp 4 and the rotating shaft 5 smoother.

[0021] The present invention is further configured as follows: the clamp 4 includes a plurality of jaws 41, a rack 42, a disc 43, a central tube 45, a retaining spring 46, and a turntable 47. The plurality of jaws 41 are arranged in a circular array. The lower end of the jaws 41 is provided with a rack 42. The middle part of the disc 43 is provided with a central hole and a plurality of sliding grooves 44 are provided radially. The sides of the jaws 41 are slidably connected in the sliding grooves 44. The lower surface of the disc 43 is fixedly connected to the top of the central tube 45. The turntable 47 is sleeved on the central tube 45. The turntable 47 is provided with a threaded groove 48, which meshes with the rack 42. The retaining spring 46 is connected to the lower end of the central tube 45 and abuts against the turntable 47.

[0022] Because the snap ring 46 is engaged with the lower end of the central tube 45, the turntable 47 is attached to the disc body 43. By rotating the turntable 47, the threaded groove 48 pushes the rack 42 towards the center of the threaded groove 48. Since the grippers 41 can only slide in the groove 44, several grippers 41 move together towards the central hole until the workpiece 8 is clamped. The side of the disc body 43 is fixedly connected to the rotating shaft 5. The structure of the fixture 4 is not limited to this; other fixtures capable of clamping the workpiece 8 are also applicable to this patent application.

[0023] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
