Description

Technical Field

[0001] This utility model relates to the field of flipping device technology, specifically a flipping device for processing precision metal structural parts. Background Technology

[0002] In aerospace, high-end equipment manufacturing, and precision instruments, the machining accuracy of precision metal structural components directly determines the performance and reliability of the final product. These components typically require multiple machining processes, including milling, grinding, and drilling, and frequent flipping and angle adjustments are necessary during machining to achieve precise multi-faceted machining. Therefore, extremely high requirements are placed on the clamping stability, motion coordination, adaptability, and safety of the flipping device.

[0003] Application number CN202323580221.4 discloses a flipping device for mold steel processing, including a base. A mounting groove is formed in the center of the upper surface of the base. A rotating assembly is rotatably connected inside the mounting groove. A mounting seat is fixedly connected to the upper surface of the rotating assembly. An electric slide rail is fixedly connected to the center of the upper surface of the mounting seat. An electric slider is slidably connected to the upper surface of the electric slide rail. A moving plate is fixedly connected to the upper surface of the electric slider. A fixed plate is fixedly connected to one side of the upper surface of the mounting seat. Clamping components are provided on the upper outer surfaces of both the moving plate and the fixed plate. In this invention, by activating the rotating assembly, the mounting seat can be rotated through the cooperation of the limiting block and the limiting groove, which in turn drives the clamping components to rotate. This allows for adjustment of the material orientation, reduces the use of the device, and improves processing convenience.

[0004] The device uses an electric slide rail to move an electric slider and a moving plate, which are then clamped together with the clamping components on the fixed plate. However, it lacks a precise guide and limiting structure. On the one hand, when the electric slider slides on the electric slide rail, it relies solely on the slide rail itself for limiting. Over time, wear on the slide rail can cause the slider to slip and deviate, making it impossible for the clamping components of the moving plate and the fixed plate to maintain alignment. This results in misalignment of the mold steel clamping and affects machining accuracy. On the other hand, no synchronous adjustment mechanism for the clamping components is mentioned. If there are slight deviations in the dimensions of the mold steel, unilateral movement of the moving plate may lead to uneven clamping force. The mold steel may loosen during the flipping process, potentially causing safety hazards. This device fails to meet the high requirements for clamping stability in precision mold steel machining. Utility Model Content

[0005] The purpose of this invention is to provide a flipping device for machining precision metal structural parts, which solves the problem of insufficient clamping stability and difficulty in adapting to precision machining requirements.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a flipping device for machining precision metal structural parts, comprising a drive assembly and a clamping assembly. The clamping assembly is mounted on the bottom inner wall of the drive assembly. The drive assembly includes a mounting shell with a mounting groove inside. A limit frame is fixedly mounted on the inner wall of the mounting groove. A fixed gear is provided in the central groove of the limit frame. Slide rail assemblies are respectively provided opposite to each other on the inner walls of the two sides of the limit frame. A connecting plate is fixedly connected to the slider of the slide rail assembly. A rack is provided on the adjacent side of the two connecting plates. The fixed gear meshes with the racks on both sides. The bottom outer sides of the two connecting plates extend downward to the outside of the mounting shell and are fixedly mounted with clamping blocks. The two clamping blocks are on the same horizontal line.

[0007] The purpose of this setup is that, during the operation of the device, after the device is started, the fixed gear is the core of power transmission, the slider of the slide rail assembly is fixed to the connecting plate, the rack of the connecting plate meshes with the fixed gear, and the rotation of the gear is converted into linear motion of the connecting plate. When the fixed gear rotates clockwise, the racks on both sides drive the connecting plate to slide in the opposite direction; when it rotates counterclockwise, the movement direction is opposite. The slide rail provides guidance for the slider to prevent the connecting plate from shifting laterally. The bottom end of the connecting plate extends outside the mounting shell. The fixed clamping blocks are on the same horizontal line and move synchronously with the connecting plate: when the clamping blocks are close, they clamp the metal structural parts, and when they are far away, they release them. The limit frame is set horizontally with the clamping blocks to ensure accurate and stable clamping and meet the needs of precision machining. The gears and racks mesh directly, resulting in a short transmission path and low loss. The limit frame prevents changes in meshing clearance, ensuring smooth movement and uniform force of the clamping blocks. The gears can be rotated to adjust the opening and closing of the clamping blocks, adapting to workpieces of different sizes. No parts need to be replaced, reducing costs and improving versatility.

[0008] Furthermore, a drive motor is fixedly mounted on the top of the mounting housing, and the fixed gear is fixedly sleeved on the output shaft of the drive motor.

[0009] The purpose of this setup is that, during the operation of the device, when the device is started, the drive motor on the top of the mounting housing runs, the fixed gear is fixedly sleeved on the motor output shaft, the motor drives the output shaft to rotate, and directly drives the fixed gear to rotate.

[0010] Furthermore, a controller is provided on one side of the drive motor, and a heat sink is provided on the top of the mounting housing.

[0011] The purpose of this setup is that, during the use of the device, the controller on the drive motor side adjusts the motor's start / stop and speed according to processing requirements. For example, when clamping, the motor is started and adjusted to the appropriate speed, and when clamping stops, the motor is controlled to stop. The heat sink on the top of the mounting shell covers the motor, preventing external impurities from entering during long-term motor operation, while also assisting in heat dissipation to avoid the motor overheating and affecting stability.

[0012] Furthermore, the drive motor is located inside the heat sink, and a fixed-point rotating shaft is fixedly installed on the inner wall of the middle part of the limiting frame.

[0013] The purpose of this design is that, during the operation of the device, when the drive motor is inside the heat sink and generates heat, the heat sink forms a closed heat dissipation space, reducing heat dissipation and protecting the motor from collisions and dust interference. The fixed-point rotating shaft in the middle of the limit frame provides a stable rotation axis for the fixed gear, preventing the gear from rotating off-center, ensuring precise meshing between the gear and rack, and ensuring stable power transmission.

[0014] Furthermore, the output end of the drive motor extends vertically downward and is positioned on the inner wall of the rotating shaft.

[0015] The purpose of this design is that, during the use of the device, after the drive motor starts, the output end extends downward and connects to the inner wall of the fixed-point rotating shaft. When the output shaft rotates, the rotating shaft serves as an auxiliary support, reducing the sway caused by the shaft length.

[0016] Furthermore, the mounting shell has limit grooves on the bottom surface of the two connecting plates at the bottom of the moving path, and the two limit grooves are spaced apart.

[0017] The purpose of this design is that, during the use of the device, when the connecting plate drives the clamping block to move, the bottom end moves along the limiting groove on the bottom surface of the mounting shell. The limiting groove matches the moving path of the connecting plate, and the secondary limiting prevents longitudinal deviation. The distance between the two limiting grooves limits the maximum approach distance of the connecting plate, preventing the clamping block from excessively clamping and damaging the workpiece, and ensuring safe and reliable clamping.

[0018] This utility model has the following beneficial effects: (1) This utility model uses gears, racks and limit frames to set up gears and racks. The gears and racks mesh directly, resulting in a short transmission path and low loss. The limit frames prevent changes in meshing gap, ensuring smooth movement and uniform force of the clamping blocks. The gears can adjust the opening and closing of the clamping blocks by rotating them forward and backward, adapting to workpieces of different sizes. No parts need to be replaced, reducing costs and improving versatility.

[0019] (2) By setting up a heat sink and a fixed-point rotating shaft, the drive motor is inside the heat sink. When it generates heat during operation, the heat sink forms a closed heat dissipation space, reducing heat diffusion and protecting the motor from collisions and dust interference. The fixed-point rotating shaft in the middle of the limit frame provides a stable rotation axis for the fixed gear, preventing the gear from rotating off-center, ensuring accurate meshing between the gear and the rack, and ensuring stable power transmission.

[0020] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0024] Please see Figures 1-5As shown, this utility model is a flipping device for processing precision metal structural parts, including a drive assembly 1 and a clamping assembly 2. The clamping assembly 2 is installed on the bottom inner wall of the drive assembly 1. The drive assembly 1 includes a mounting shell 101. The mounting shell 101 has a mounting groove 107 inside. A limit frame 108 is fixedly installed on the inner wall of the mounting groove 107. A fixed gear 105 is provided in the groove in the middle of the limit frame 108. Slide rail assemblies 201 are respectively provided on the inner walls of the two sides of the limit frame 108. A connecting plate 202 is fixedly connected to the slider of the slide rail assembly 201. A rack 203 is provided on the adjacent side of the two connecting plates 202. The fixed gear 105 is meshed with the rack 203 on both sides. The bottom outer side of the two connecting plates 202 extends downward to the outside of the mounting shell 101 and is fixedly installed with clamping blocks 204. The two clamping blocks 204 are on the same horizontal line.

[0025] The purpose of this setup is that, during the use of the device, after the device is started, the fixed gear 105 is the core of power transmission, the slider of the slide rail assembly 201 is fixed to the connecting plate 202, the rack 203 of the connecting plate 202 meshes with the fixed gear 105, and the rotation of the gear is converted into the linear motion of the connecting plate 202. When the fixed gear 105 rotates clockwise, the racks 203 on both sides drive the connecting plate 202 to slide in the opposite direction; when it rotates counterclockwise, the movement direction is opposite. The slide rail provides guidance for the slider to prevent the connecting plate 202 from shifting laterally. The bottom end of the connecting plate 202 extends outside the mounting shell 101. The fixed clamping block 204 is on the same horizontal line and moves synchronously with the connecting plate 202. When the clamping block 204 is close, it clamps the metal structural parts and releases them when it is far away. The limit frame 108 is set horizontally with the clamping block 204 to ensure accurate and stable clamping and meet the needs of precision machining. The gear and rack 203 mesh directly, resulting in a short transmission path and low loss. The limit frame 108 prevents changes in meshing clearance, and the clamping block 204 moves smoothly with uniform force. The gear can be adjusted to open and close the clamping block 204 in both forward and reverse directions, adapting to workpieces of different sizes without the need to replace parts, thus reducing costs and improving versatility.

[0026] A drive motor 103 is fixedly mounted on the top of the mounting housing 101, and a fixed gear 105 is fixedly sleeved on the output shaft of the drive motor 103.

[0027] The purpose of this arrangement is that, during the use of the device, when the device is started, the drive motor 103 on the top of the mounting housing 101 runs, the fixed gear 105 is fixedly sleeved on the motor output shaft, the motor drives the output shaft to rotate, and directly drives the fixed gear 105 to rotate.

[0028] A controller 104 is provided on one side of the drive motor 103, and a heat sink 102 is provided on the top of the mounting housing 101.

[0029] The purpose of this setup is that, during the use of the device, the controller 104 on one side of the drive motor 103 adjusts the start-stop and speed of the motor according to the processing requirements. For example, when clamping, the motor is started and adjusted to the appropriate speed, and when clamping stops, the motor is controlled to stop. The heat sink 102 at the top of the mounting shell 101 covers the motor, which prevents external impurities from entering when the motor is running for a long time, and at the same time assists in heat dissipation to avoid the motor overheating and affecting stability.

[0030] The drive motor 103 is located inside the heat sink 102, and a fixed rotating shaft 106 is fixedly installed on the inner wall of the middle part of the limit frame 108.

[0031] The purpose of this arrangement is that during the use of the device, when the drive motor 103 is inside the heat sink 102 and generates heat, the heat sink 102 forms a closed heat dissipation space, reducing heat diffusion and protecting the motor from collisions and dust interference. The fixed-point rotating shaft 106 in the middle of the limit frame 108 provides a stable rotation axis for the fixed gear 105, preventing gear rotation deviation, ensuring accurate meshing between the gear and the rack 203, and ensuring stable power transmission.

[0032] The output end of the drive motor 103 extends vertically downward and is fixed on the inner wall of the rotating shaft 106.

[0033] The purpose of this design is that, during the use of the device, after the drive motor 103 starts, the output end extends downward and connects to the inner wall of the fixed-point rotating shaft 106. When the output shaft rotates, the rotating shaft serves as an auxiliary support, reducing the sway caused by the shaft length.

[0034] The mounting housing 101 has limit grooves 109 on the bottom surface at the movement path of the two connecting plates 202, and the two limit grooves 109 are spaced apart.

[0035] The purpose of this design is that, during the use of the device, when the connecting plate 202 drives the clamping block 204 to move, the bottom end moves along the limiting groove 109 on the bottom surface of the mounting shell 101. The limiting groove 109 matches the movement path of the connecting plate 202, and the secondary limiting prevents longitudinal deviation. The distance between the two limiting grooves 109 limits the maximum approach distance of the connecting plate 202, preventing the clamping block 204 from excessively clamping and damaging the workpiece, and ensuring safe and reliable clamping.

[0036] When in use, place the metal structural parts between the two clamping blocks 204 and align them. The operator sends a command through the controller 104 to control the drive motor 103 to start and adjust it to the preset speed. The heat sink 102 blocks impurities and prepares for auxiliary heat dissipation. After the motor starts, the output shaft drives the fixed gear 105 to rotate. The motor output end is connected to the fixed rotating shaft 106. The rotating shaft provides a stable axis for the output shaft and gear to prevent deviation. The limit bracket 108 laterally positions the gear to ensure that the gear and rack 203 mesh accurately. The fixed gear 105 rotates, which drives the rack 203 through meshing. The connecting plate 202 moves linearly along the slide rail with the slider of the slide rail assembly 201 to avoid lateral deviation. The connecting plate 202 drives the clamping block 204 to move. When it gets close, it clamps the workpiece to the preset force. When it is released, the motor reverses and the clamping block 204 moves away. When the connecting plate 202 moves, the limiting groove 109 provides secondary limiting to prevent longitudinal displacement, the groove spacing anti-clamping block 204 prevents over-clamping, and the heat generated by the motor is dissipated through the heat sink 102 to avoid overheating and shutdown. Each component has a clear division of labor, achieving safe and precise clamping to meet processing requirements.
