Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a rotating bracket for mechanical parts. Background Technology

[0002] In manufacturing housings for precision electronic devices, sheet metal parts often require multi-faceted punching to meet functional requirements such as interfaces, heat dissipation holes, or mounting holes. Traditional fixtures typically only clamp a single plane of the sheet metal part; after punching one side, it must be disassembled and re-clamped to the other side before further processing can begin. This method is not only cumbersome and time-consuming, but the repeated disassembly and reassembly can also easily cause scratches or deformation on the sheet metal surface. Furthermore, positioning errors in each clamping operation make it difficult to ensure good positional consistency between the holes, affecting assembly accuracy and overall quality, and reducing production efficiency and yield. Therefore, we propose a rotating bracket for mechanical parts. Utility Model Content

[0003] The main objective of this invention is to provide a rotating bracket for mechanical parts, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A rotating bracket for mechanical parts includes a support frame, a clamping mechanism movably connected to the front end of the support frame, a rotating mechanism provided at the rear end of the support frame, and the rotating mechanism being drivenly connected to the clamping mechanism. A protective shell for protecting the rotating mechanism is fixedly installed at the rear end of the support frame, and a control module and a power module are fixedly installed at the rear end of the support frame, with both the control module and the power module located inside the protective shell.

[0006] The rotating mechanism includes a fixed frame, which is fixedly installed at the rear end of the support frame. The lower end of the fixed frame is fixedly connected to two slide rails arranged symmetrically on the left and right. A sliding sleeve is slidably connected to both slide rails. A drive rack is fixedly connected to the rear end of the sliding sleeve. The upper end of the fixed frame is fixedly installed with two electric telescopic rods. The output ends of the two electric telescopic rods pass through the fixed frame and are fixedly connected to the sliding sleeve.

[0007] Preferably, the clamping mechanism includes a clamping assembly, the rear end of which is fixedly connected to a rotating rod, the rear end of which passes through a support frame and is fixedly connected to a transmission gear, and the rotating rod is movably connected to the support frame via a bearing.

[0008] Preferably, the transmission gear is located behind the fixed frame and does not contact the fixed frame. The transmission gear and the drive rack are located on the same plane and mesh with each other to drive the rotation mechanism and the clamping mechanism.

[0009] By adopting the above technical solution, the rotation control of the clamping component is achieved by driving the rack and pinion to mesh with the transmission gear, so that the sheet metal parts can be adjusted in space angle and flipped without disassembly, which facilitates continuous processing of multiple surfaces of the parts.

[0010] Preferably, the clamping assembly includes a rotating beam, the rear end of which is fixedly connected to the front end of the rotating rod. Two clamping arms slidably connected to the rotating beam are arranged symmetrically on the left and right sides. Support seats are fixedly connected to the upper left and right sides of the rotating beam. A positive and negative lead screw is movably mounted on both support seats. A positive and negative motor is fixedly mounted on the support seats, and the output end of the positive and negative motor is fixedly connected to one end of the positive and negative lead screw. A transmission lug that is threadedly connected to the positive and negative lead screw is fixedly connected to the upper end of the clamping arm.

[0011] Preferably, the threads on the left and right sides of the outer surface of the positive and negative lead screw are reversed, and the two clamping arms are respectively threaded to the left and right sides of the positive and negative lead screw.

[0012] By adopting the above technical solution, the clamping arms move synchronously towards or away from each other on the rotating beam, ensuring uniform distribution of clamping force and enabling fast and stable clamping and fixing of sheet metal parts of different sizes and thicknesses.

[0013] Preferably, each of the two clamping arms has a placement groove at its opposite ends, and both ends of the placement groove are closed structures.

[0014] By adopting the above technical solution: In order to effectively protect the sheet metal parts, a rubber pad can be fixedly connected in the placement groove to avoid damage caused by contact between the sheet metal parts and the inner wall of the placement groove.

[0015] Preferably, the clamping arm is connected to an adjusting screw, and the adjusting screw is threadedly connected to the front part of the clamping arm. The rear end of the adjusting screw is movably connected to a stop block, and the stop block is slidably connected in the placement groove. The front end of the adjusting screw is fixedly connected to a rotating handle.

[0016] By adopting the above technical solution, the parts are further pressed by manually adjusting the stop block with the handle, which effectively prevents displacement or loosening caused by vibration or rotation during the processing, significantly improving the clamping firmness and the safety of the processing, and is suitable for precision machining needs under various complex working conditions.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The electric telescopic rod drives the sliding sleeve and drive rack to move, and engages with the transmission gear to realize the rotation control of the clamping component. This allows the sheet metal parts to complete spatial angle adjustment and flipping operations without disassembly, which is convenient for continuous processing of multiple surfaces of the parts. This angle adjustment method, which is achieved by the linkage of the rotation mechanism and the clamping mechanism, is not only compact and precise in control, but also avoids the efficiency loss and positioning error caused by repeated clamping in traditional processing, which greatly improves processing efficiency and consistency. It is particularly suitable for high-efficiency operation scenarios in automated production lines.

[0019] 2. By setting up a double clamping arm structure driven by positive and negative lead screws, and combining it with the auxiliary clamping design of adjusting screws and abutments, the clamping arms move synchronously towards or away from each other on the rotating beam, ensuring uniform clamping force distribution and enabling fast and stable clamping and fixing of sheet metal parts of different sizes and thicknesses. At the same time, the abutments can be manually adjusted by the handle to further press the parts, effectively preventing displacement or loosening caused by vibration or rotation during processing, significantly improving the clamping firmness and processing safety, and making it suitable for precision machining needs under various complex working conditions.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Please see Figure 1-4 This utility model provides a technical solution:

[0029] A rotating bracket for mechanical parts includes a support frame 1. A clamping mechanism 2 is movably connected to the front end of the support frame 1. A rotating mechanism 3 is provided at the rear end of the support frame 1, and the rotating mechanism 3 is connected to the clamping mechanism 2 in a transmission manner. A protective shell 4 for protecting the rotating mechanism 3 is fixedly installed at the rear end of the support frame 1. A control module 6 and a power module 7 are fixedly installed at the rear end of the support frame 1, and both the control module 6 and the power module 7 are located inside the protective shell 4.

[0030] In this embodiment, the rotating mechanism 3 includes a fixed frame 31, which is fixedly installed at the rear end of the support frame 1. The lower end of the fixed frame 31 is fixedly connected to two slide rails 32 arranged symmetrically on the left and right. A sliding sleeve 33 is slidably connected to both slide rails 32. A drive rack 34 is fixedly connected to the rear end of the sliding sleeve 33. Two electric telescopic rods 35 are fixedly installed at the upper end of the fixed frame 31. The output ends of the two electric telescopic rods 35 pass through the fixed frame 31 and are fixedly connected to the sliding sleeve 33. The clamping mechanism 2 includes a clamping assembly 21, which is fixedly connected to the rear end of the clamping assembly 21. A rotating rod 22 passes through the support frame 1 and is fixedly connected to a transmission gear 23. The rotating rod 22 is movably connected to the support frame 1 through a bearing. The transmission gear 23 is located behind the fixed frame 31 and does not contact the fixed frame 31. The transmission gear 23 and the drive rack 34 are located on the same plane and mesh with each other to drive the rotating mechanism 3 and the clamping mechanism 2.

[0031] The above solution involves using an electric telescopic rod 35 to move the sliding sleeve 33 and the drive rack 34, which mesh with the transmission gear 23 to achieve rotation control of the clamping assembly 21. This allows the sheet metal part 5 to complete spatial angle adjustment and flipping operations without disassembly, facilitating continuous processing of multiple surfaces of the part. This angle adjustment method, achieved by the linkage between the rotating mechanism 3 and the clamping mechanism 2, is not only compact and precise in control, but also avoids the efficiency loss and positioning errors caused by repeated clamping in traditional processing, significantly improving processing efficiency and consistency. It is particularly suitable for high-efficiency operation scenarios in automated production lines.

[0032] In this embodiment, the clamping assembly 21 includes a rotating beam 211, the rear end of which is fixedly connected to the front end of the rotating rod 22. Two clamping arms 212, symmetrically distributed on the left and right, are slidably connected to the rotating beam 211. Support seats 213 are fixedly connected to the left and right sides of the upper end of the rotating beam 211. A forward and reverse lead screw 215 is movably mounted on both support seats 213. A forward and reverse motor 214 is fixedly mounted on the support seats 213, and the output end of the forward and reverse motor 214 is fixedly connected to one end of the forward and reverse lead screw 215. A transmission mechanism threadedly connected to the forward and reverse lead screw 215 is fixedly connected to the upper end of the clamping arm 212. Ear 216; The threads on the left and right sides of the outer surface of the positive and negative lead screw 215 are reversed. Two clamping arms 212 are threadedly connected to the left and right sides of the positive and negative lead screw 215 respectively. Each of the two clamping arms 212 has a placement groove 2121 at its opposite end, and both ends of the placement groove 2121 are closed. An adjusting screw 217 is inserted and connected to the clamping arm 212. The adjusting screw 217 is threadedly connected to the front part of the clamping arm 212. A stop block 218 is movably connected to the rear end of the adjusting screw 217. The stop block 218 is slidably connected in the placement groove 2121. A rotating handle 219 is fixedly connected to the front end of the adjusting screw 217.

[0033] Through the above scheme: after the sheet metal part 5 is firmly clamped, the control module 6 starts the electric telescopic rod 35 according to the preset program or manual operation command. The electric telescopic rod 35 pushes the sliding sleeve 33 to move back and forth along the slide rail 32, thereby driving the drive rack 34 to move. Since the drive rack 34 is meshed with the transmission gear 23, the linear motion of the drive rack 34 is converted into the rotational motion of the transmission gear 23. Thus, the clamping assembly 21 is driven to rotate around the support frame 1 through the rotating rod 22, realizing the multi-angle adjustment of the sheet metal part 5 in space, meeting the multi-face processing requirements, avoiding frequent disassembly of the sheet metal part 5, and improving processing efficiency and stability.

[0034] It should be noted that this utility model is a rotating bracket for mechanical parts. During use, the sheet metal part 5 to be processed is first placed between two clamping arms 212. Then, the forward and reverse motor 214 is started, driving the forward and reverse lead screws 215 to rotate. Since the threads on the left and right sides of the forward and reverse lead screws 215 are opposite, the two clamping arms 212 will move synchronously towards or away from each other on the rotating beam 211, thereby clamping and fixing the sheet metal part 5 in the placement grooves 2121 on the two clamping arms 212. Then, the handle 219 is rotated, driving the adjusting screw 217 to rotate. The adjusting screw 217 pushes the abutment 218 to slide backward within the placement grooves 2121, making it tightly adhere to the sheet metal part 5. The front surface of the sheet metal part 5 is further enhanced to improve the stability and reliability of the clamping, preventing displacement or loosening of the sheet metal part 5 during subsequent rotation or processing. After the sheet metal part 5 is firmly clamped, the control module 6 starts the electric telescopic rod 35 according to the preset program or manual operation command. The electric telescopic rod 35 pushes the sliding sleeve 33 to move back and forth along the slide rail 32, thereby driving the drive rack 34 to move. Since the drive rack 34 is meshed with the transmission gear 23, the linear motion of the drive rack 34 is converted into the rotational motion of the transmission gear 23, thereby driving the clamping assembly 21 to rotate around the support frame 1 through the rotating rod 22, realizing the multi-angle adjustment of the sheet metal part 5 in space, meeting the multi-face processing requirements, avoiding frequent disassembly of the sheet metal part 5, and improving processing efficiency and stability.
