Technical Field

[0001] This utility model relates to the field of gear processing technology, specifically a rotating frame. Background Technology

[0002] Gear machining is a process that uses mechanical methods to obtain gears with specific structures and precision. Gears are the core transmission components in mechanical motion, and the quality of their machining directly affects the vibration, noise, and reliability of mechanical assemblies and even the entire mechanical device. Sometimes, it can become a key factor restricting the improvement of product quality.

[0003] The patent application with publication number CN213969346U discloses a rotary gear processing frame, including a support arm, a motor for adjusting the rotation angle of the gear, and a cylinder for positioning the gear. A rotating base is provided on the front side of the support arm, and a retaining ring is rotatably provided inside the rotating base. A metal tongue for limiting the rotation center of the gear is provided on the front side of the retaining ring, and a screw for locking the gear is provided in the middle of the retaining ring. A gear disk is connected to the rear side of the retaining ring, and a worm gear is connected to the motor drive shaft, and the worm gear meshes with the gear disk gear. A base perpendicular to the support arm is integrally provided on the lower side of the support arm, and the cylinder is located on the lower side of the base. A support block for positioning the gear is connected to the drive shaft of the cylinder.

[0004] The above-mentioned device is only suitable for gears of a single specification and is not suitable for workpieces with different inner hole radii. The same workpiece cannot accommodate gear parts of different specifications. Therefore, we propose a rotating frame. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a rotating frame. By adjusting the spacing between the symmetrically arranged left and right support plates through an adjustment component, two conical blocks can be inserted and combined with each other through their respective slots. At the same time, the mutual proximity of the two conical blocks supports and fixes the inner hole of the gear, thereby enabling the fixing of gears with different inner hole sizes.

[0006] In order to solve the above-mentioned technical problems, the present invention solves the problem that the rotating frame can only hold gears with specific inner hole sizes, which is not very adaptable, through the following technical solution.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A rotating frame, relating to the field of gear processing technology, includes a base, a conical block, and an adjustment assembly. The base has symmetrically distributed left and right support plates. A rotating disk is rotatably mounted on the outer sides of the left and right support plates. A drive motor is fixedly mounted on the side of the left support plate away from the rotating disk, and the output end of the drive motor is fixed to the axis of the rotating disk. The conical block is fixedly mounted on the outer side of the rotating disk, supporting the inner hole of a gear. The conical block has evenly distributed slots. An inner shaft is fixedly mounted inside the conical block on the left support plate, and an inner cavity for insertion and connection with the inner shaft is located inside the conical block on the right support plate. An adjustment assembly for adjusting the distance between the left and right support plates is mounted on the base.

[0009] Preferably, the adjustment assembly includes a positive and negative lead screw, a groove on the top of the base, the positive and negative lead screw rotatably disposed within the groove, an adjustment motor fixedly disposed on the outside of the base, the output end of the adjustment motor fixed to the end of the positive and negative lead screw, symmetrically distributed slide blocks are threaded on the positive and negative lead screw, the slide blocks slidably disposed within the groove, a left support plate and a right support plate are respectively fixed to the top of the two slide blocks, the positive and negative lead screw drives the two slide blocks to move closer or further apart, and while adjusting the distance between the left support plate and the right support plate, it can ensure that the gear held by the two conical blocks is directly above the center of the base.

[0010] Preferably, there are three slots, evenly distributed on the outside of the conical block. Two conical blocks are connected to each other through the slots. By setting three slots, it is possible to ensure that two conical blocks can be connected and combined while also ensuring that the clamping force generated by the conical blocks on both sides of the gear is uniform.

[0011] Preferably, the outer side of the inner shaft is provided with uniformly distributed grooves, which are located in the groove opening. The inner cavity is fixed with uniformly distributed inserts, which are located on the inner side of the conical block of the right support plate. The inserts slide and engage with the grooves, thereby improving the positioning accuracy when the two conical blocks are inserted.

[0012] Preferably, both the groove and the insert are T-shaped to ensure the connection strength after the two conical blocks are inserted and to prevent the tip of the conical block with the inner cavity from turning outward.

[0013] Preferably, the two conical blocks are coaxial to ensure uniform pressure on both sides of the gear when the two conical blocks clamp the gear.

[0014] Preferably, the groove is 60°, and the three grooves are distributed in a triangle on the conical block to ensure the balance of left and right pressure when the gear is clamped, so that the gear always remains vertical when it is rotated by the conical block.

[0015] Preferably, support blocks are fixed on the sides of the left and right support plates that are far apart from each other. The bottom of the support blocks is fixed to the top of the slide block to distribute the bending stress on the bottom of the left and right support plates when clamping the gear.

[0016] Preferably, the support block is triangular, which provides greater stability.

[0017] Preferably, the outer side of the support block has evenly distributed slots, which reduces the amount of material used in the support block while ensuring its support strength.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This utility model adjusts the distance between the symmetrically arranged left and right support plates by adjusting the component, allowing the two conical blocks to be inserted and combined with each other through their respective slots. At the same time, the mutual proximity of the two conical blocks supports and fixes the inner hole of the gear, thereby enabling the fixing of gears with different inner hole sizes.

[0020] By setting three 60° slots on each conical block, and the three slots being distributed in a triangle, the force applied when the conical block clamps the inner hole of the gear is uniform, ensuring that the clamped gear will not deflect when rotating together with the conical block.

Example

[0033] Please see Figures 1-6 A rotating frame, relating to the field of gear processing technology, includes a base 1, a conical block 6, and an adjustment assembly 10. The conical block 6 is made of stainless steel, which has higher strength. The base 1 is provided with a left support plate 2 and a right support plate 3 that are symmetrically distributed. A rotating disk 4 is rotatably provided on the outer side of the left support plate 2 and the right support plate 3. A drive motor 5 is fixed on the side of the left support plate 2 away from the rotating disk 4. The drive motor 5 is a three-phase asynchronous motor, which is easy to maintain and has a relatively low cost.

[0034] The output end of the drive motor 5 is fixed to the axis of the rotating disk 4. A conical block 6 is fixedly mounted on the outside of the rotating disk 4. The two conical blocks 6 are coaxial, ensuring uniform pressure on both sides of the gear when the two conical blocks 6 clamp it. The conical blocks 6 support the inner hole of the gear, and evenly distributed slots 7 are provided inside the conical blocks 6. Figure 6 As shown, there are three slots 7, each slot 7 is 60°, and the three slots 7 are evenly distributed in a triangle on the outside of the conical block 6. The two conical blocks 6 are connected to each other through the slots 7. By setting three slots 7, it is possible to ensure that the two conical blocks 6 can be connected and combined, while also ensuring that the clamping force generated by the conical blocks 6 on both sides of the gear is uniform.

[0035] An inner shaft 8 is fixedly installed inside the tapered block 6 on the left support plate 2, and an inner cavity 9 is provided inside the tapered block 6 on the right support plate 3 that is inserted and combined with the inner shaft 8. An adjustment component 10 for adjusting the distance between the left support plate 2 and the right support plate 3 is provided on the base 1.

[0036] The following describes some embodiments of this application in detail with reference to the accompanying drawings:

[0037] Please see Figures 1-6 By adjusting the distance between the symmetrically arranged left support plate 2 and right support plate 3 through the adjusting component 10, the two conical blocks 6 can be inserted and combined with each other through their respective slots 7. At the same time, the mutual proximity of the two conical blocks 6 supports and fixes the inner hole of the gear, thereby achieving the fixation of gears with different inner hole sizes.

[0038] The adjustment assembly 10 includes a positive and negative lead screw 11. The top of the base 1 is provided with a slide groove 12, and the positive and negative lead screw 11 is rotatably disposed in the slide groove 12. An adjustment motor 13 is fixedly disposed on the outside of the base 1. The output end of the adjustment motor 13 is fixed to the end of the positive and negative lead screw 11. The adjustment motor 13 is a three-phase stepper motor, which can accurately control the rotation accuracy of the positive and negative lead screw 11. The positive and negative lead screw 11 is threaded with symmetrically distributed slide blocks 14, which are slidably disposed in the slide groove 12. The left support plate 2 and the right support plate 3 are respectively fixed to the top of the two slide blocks 14. The positive and negative lead screw 11 drives the two slide blocks 14 to move closer or further away from each other. While adjusting the distance between the left support plate 2 and the right support plate 3, it can ensure that the gear held by the two conical blocks 6 is directly above the center of the base 1.

[0039] To achieve the effect of clamping and fixing gears with different inner hole sizes, the embodiments of this application are described as follows:

[0040] First, by adjusting the operation of the motor 13, the positive and negative lead screws 11 are rotated, thereby causing the two slide blocks 14 to move closer to each other, and then causing the left support plate 2 and the right support plate 3 to move closer to each other.

[0041] During this process, the two conical blocks 6 on the left support plate 2 and the right support plate 3 are connected to each other through their respective slots 7. The mutual proximity of the two conical blocks 6 supports and fixes the inner hole of the gear, thereby enabling the fixing of gears with different inner hole sizes.

[0042] Finally, by driving the rotating disk 4 to rotate via the drive motor 5, the conical block 6 and the clamped gear can be driven to rotate synchronously.

[0043] It is worth noting that the triangularly distributed slots 7 on the conical block 6 ensure that the contact area between the conical block 6 and the gear is also triangularly distributed, thereby ensuring that the force applied by the conical block 6 to the gear is uniform and that the clamped gear will not deflect when it rotates together with the conical block 6.

[0044] In some embodiments of this technical solution, in order to improve the support strength of the left support plate 2 and the right support plate 3, such as... Figure 1 and Figure 2 As shown, support blocks 17 are fixed on the sides of the left support plate 2 and the right support plate 3 that are far apart from each other. The bottom of the support block 17 is fixed to the top of the slide block 14, which disperses the bending stress on the bottom of the left support plate 2 and the right support plate 3 when clamping the gear. At the same time, the support block 17 is set in a triangular shape, which makes it more stable. In addition, by setting evenly distributed slots 18 on the outside of the support block 17, the support strength of the support block 17 can be guaranteed while reducing the amount of material used in the support block 17.

[0045] In some embodiments of this technical solution, to prevent the two conical blocks 6 from flipping outwards when they are inserted into each other, such as... Figures 4-6 As shown, the inner shaft 8 has uniformly distributed grooves 15 on its outer side, which are located inside the slot 7. The inner cavity 9 has uniformly distributed inserts 16 fixed inside, which are located inside the conical block 6 of the right support plate 3. The inserts 16 slide into the grooves 15. When the two conical blocks 6 are inserted into each other, the inner shaft 8 is inserted into the inner cavity 9, and the inserts 16 are also inserted into the grooves 15. This can improve the positioning accuracy when the two conical blocks 6 are inserted. At the same time, setting both the grooves 15 and the inserts 16 to be T-shaped can ensure the connection strength after the two conical blocks 6 are inserted, thereby preventing the tip of the conical block 6 with the inner cavity 9 from turning outward when the two conical blocks 6 are inserted into each other.

[0046] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the principles, the implementation of the present invention may have any modifications or variations.
