Description

Technical Field

[0001] This utility model relates to the field of fixing fixture technology, specifically a planetary carrier fixing fixture that is easy to operate. Background Technology

[0002] The planetary carrier plays a crucial role in planetary gear reducers. It is one of the main components of a planetary gear transmission device, housing the planetary gear shafts or bearings. The primary function of the planetary carrier is to support the planetary gears, enabling them to run stably on specific tracks. Machine tool planetary carrier fixing fixtures possess multiple functional characteristics that contribute to their excellent performance during machining. First, the fixture has a high-precision positioning function, ensuring the precise position of the planetary carrier during machining. Second, the fixture's clamping force is stable and reliable, effectively preventing the planetary carrier from shaking or shifting during machining. Furthermore, the fixture is easy to operate, facilitating quick replacement by workers. However, a current technical drawback of easy-to-operate planetary carrier fixing fixtures is that only one fixture can be fixed at a time, preventing continuous machining, resulting in low work efficiency, and inconvenience in clamping and quick replacement. Therefore, this invention addresses these issues through in-depth research. Utility Model Content

[0003] The purpose of this utility model is to provide a convenient fixing fixture for planetary carriers, so as to solve the problem mentioned in the background art that the existing convenient fixing fixture for planetary carriers does not have the advantages of easy clamping and fixing and efficient processing.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a convenient fixing clamp for a planetary carrier, comprising a base, a top plate, and a circular hole. A control panel is installed on one side of the top of the base. A rotating rod is movably installed at the middle position of the top of the base via a bearing, and the top of the rotating rod is connected to a clamp body. The top of the clamp body has evenly distributed grooves, and each groove has a column installed on its inner wall. Each column has a movable ring installed on its outer wall. Each column has a top plate connected to its top. Each top plate has a clamping plate evenly installed below it. Each clamp body has a planetary carrier body installed at the top of the clamp body above the grooves, and each planetary carrier body has a circular hole at its middle position.

[0005] Preferably, a drive motor is installed inside the other side of the base, and the output end of the drive motor is connected to a drive gear through a drive shaft. A driven gear is installed on the outer wall below the rotating rod, and a meshing transmission structure is formed between the driven gear and the drive gear.

[0006] Preferably, the top view of the clamp body is circular, and the planetary carrier bodies are symmetrical about each other with respect to the center point of the clamp body.

[0007] Preferably, each of the columns is equipped with a servo motor on its inner wall, and the output end of each servo motor is connected to a lead screw via a drive shaft. Each lead screw has a movable sleeve threaded onto its outer wall, and one end of each movable sleeve is fixedly connected to the inner wall of a movable ring.

[0008] Preferably, a limiting groove is provided on the outer wall of one end of the column, and the inner wall of the movable ring is movably connected to the limiting groove through a limiting wheel.

[0009] Preferably, dampers are uniformly installed on the inner wall of the top plate, and a return spring is installed on the outer wall of one end of each damper. A connecting block is connected to one end of each damper, and the bottom end of each connecting block is fixedly connected to the clamping plate.

[0010] Preferably, the number of clamping plates is four, and the bottom view of each clamping plate is arc-shaped.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This utility model provides a planetary carrier body, a damper, and a return spring. By fitting the circular hole of the planetary carrier body onto the outside of the top plate, the servo motor drives the lead screw to rotate, and the threaded engagement causes the moving sleeve to drive the moving ring to move upward. The moving ring moves upward and then presses the four clamping plates to move outward. At the same time, the damper and the return spring are stretched and deformed. When the moving ring moves to the top, the four clamping plates move outward and press against the inner wall of the circular hole of the planetary carrier body, thus clamping and fixing the planetary carrier body, solving the problem of inconvenient clamping and fixing. This utility model provides a planetary carrier body, a driving gear, and a driven gear. By mounting four planetary carrier bodies onto a fixture body and fixing them, after machining one planetary carrier body, the driving motor is driven to rotate the driving gear. Through the meshing of the driving gear and the driven gear, the rotating rod drives the fixture body to rotate simultaneously, moving another planetary carrier body to the machining position. By continuously machining multiple planetary carrier bodies in sequence, the problem of inefficient machining is solved. Attached Figure Description

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.

[0015] Example 1: Please refer to Figures 1-6 A convenient fixing fixture for a planetary carrier includes a base 4, a top plate 12, and a circular hole 20. A control panel 1 is installed on one side of the top of the base 4. A rotating rod 8 is movably installed at the middle position of the top of the base 4 via a bearing, and the top of the rotating rod 8 is connected to a fixture body 2. The top of the fixture body 2 is evenly provided with grooves 19, and each groove 19 has a column 11 installed on its inner wall. Each column 11 has a moving ring 9 installed on its outer wall. Each column 11 has a top plate 12 connected to its top. Each top plate 12 has a clamping plate 10 evenly installed below it. Each top of the fixture body 2 above the grooves 19 has a planetary carrier body 3 installed, and each planetary carrier body 3 has a circular hole 20 at its middle position. A drive motor 6 is installed inside the other side of the base 4, and the output end of the drive motor 6 is connected to the drive gear 5 through the drive shaft. A driven gear 7 is installed on the outer wall below the rotating rod 8, and a meshing transmission structure is formed between the driven gear 7 and the drive gear 5. The top view of the fixture body 2 is circular, and the planetary carrier bodies 3 are symmetrical about each other with respect to the center point of the fixture body 2. Specifically, such as Figure 1 and Figure 2 As shown, when using this structure, four planetary carrier bodies 3 are fixed on the fixture body 2. After machining one planetary carrier body 3, the drive motor 6 is used to make the drive gear 5 rotate. The drive gear 5 meshes with the driven gear 7, causing the rotating rod 8 to drive the fixture body 2 to rotate simultaneously, so that another planetary carrier body 3 is moved to the machining position. Through the continuous machining of multiple planetary carrier bodies 3 in sequence, the machining efficiency is improved.

[0016] Example 2: Servo motors 15 are installed on the inner walls of the columns 11, and the output ends of the servo motors 15 are connected to lead screws 14 through drive shafts. The outer walls of the lead screws 14 are threaded with movable sleeves 13, and one end of the movable sleeves 13 is fixedly connected to the inner wall of the movable rings 9. Each end of the column 11 has a limit groove on its outer wall, and the inner wall of the moving ring 9 is movably connected to the limit groove through a limit wheel; Dampers 16 are evenly installed on the inner wall of the top plate 12, and a return spring 17 is installed on the outer wall of one end of each damper 16. A connecting block 18 is connected to one end of each damper 16, and the bottom end of each connecting block 18 is fixedly connected to the clamping plate 10. There are four clamping plates 10, and the bottom view of each clamping plate 10 is arc-shaped. Specifically, such as Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, when using this structure, the planetary carrier body 3 is fitted with the round hole 20 on the outside of the top plate 12. The servo motor 15 is used to rotate the lead screw 14. The threaded engagement causes the moving sleeve 13 to drive the moving ring 9 to move upward. The moving ring 9 moves upward and then presses the four clamping plates 10 to move outward. At the same time, the damper 16 and the return spring 17 are stretched and deformed. When the moving ring 9 moves to the top, the four clamping plates 10 move outward and press against the inner wall of the round hole 20 of the planetary carrier body 3, thus clamping and fixing the planetary carrier body 3.

[0017] Working principle: When using this device, first place multiple planetary carrier bodies 3 on the clamp body 2 and fix them; Implementation steps for the first innovation point: Step 1: By fitting the round hole 20 of the planetary carrier body 3 onto the outside of the top plate 12, the servo motor 15 is used to rotate the lead screw 14. The threaded engagement causes the moving sleeve 13 to drive the moving ring 9 to move upward. The moving ring 9 moves upward and then presses the four clamping plates 10 to move outward. At the same time, the damper 16 and the return spring 17 are stretched and deformed. Step 2: When the moving ring 9 reaches the top, the four clamping plates 10 move outward and press against the inner wall of the round hole 20 of the planetary carrier body 3 to clamp and fix the planetary carrier body 3.

[0018] Implementation steps for the second innovation point: By fixing four planetary carrier bodies 3 on the fixture body 2, after machining one planetary carrier body 3, the drive motor 6 is used to make the drive gear 5 rotate. The drive gear 5 meshes with the driven gear 7, causing the rotating rod 8 to drive the fixture body 2 to rotate simultaneously, so that another planetary carrier body 3 is moved to the machining position. Through the continuous machining of multiple planetary carrier bodies 3 in sequence, the machining efficiency is improved.
