Description

Technical Field

[0001] This utility model relates to the field of gear clamping technology, specifically a gear tooth surface finishing clamping device. Background Technology

[0002] A gear tooth surface finishing clamping device is a specialized device used during the finishing process of gear teeth to ensure the stable fixation of the gear workpiece. Its main functions include: ensuring the stability and accuracy of the gear during machining, preventing gear wobbling or displacement due to forces (such as cutting forces, gravity, etc.), thereby improving the machining quality and performance of the gear; at the same time, it also helps to improve machining efficiency and ensure the safety of operators.

[0003] For example, Chinese Patent Application No. 202120873333.0 discloses a gear clamping device, including an elastic base plate. One side of the elastic base plate has a driving source for deforming the elastic base plate, and the other side has at least two sets of chuck assemblies for clamping gears. Each chuck assembly includes a positioning base and hard positioning claws mounted on the positioning base. The hard positioning claws have positioning pins protruding towards the gear and capable of inserting into the gear groove. When the driving source deforms the elastic base plate, the chuck assemblies open outwards with the elastic base plate, allowing the gear to be placed between the two sets of chuck assemblies. When the driving source resets the elastic base plate, the chuck assemblies clamp and fix the gear. This invention has a simple structure, occupies little space, and can achieve automatic clamping and releasing under control, making it suitable for automated production.

[0004] In the finishing of gear teeth, commonly used clamping devices rely on universal jaws for holding the gear. However, the incomplete fit between the universal jaws and the gear surface can easily lead to loosening or displacement during machining. Secondly, the installation and removal process of the jaws is cumbersome and must be done one by one, meaning that the next jaw can only be moved after each one has been removed or installed. This greatly increases the number of operation steps and prolongs the operation time.

[0005] Therefore, it is necessary to redesign and modify the gear tooth surface finishing clamping device to effectively prevent problems such as loose clamping and inconvenient assembly and disassembly. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a gear tooth surface finishing clamping device, which has the advantages of being easy to use and solves the problems of easy clamping failure and inconvenient disassembly and assembly.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a gear tooth surface finishing clamping device, comprising a base, three movable blocks mounted on the top of the base, and a clamping structure, the clamping structure comprising multiple locking blocks fixedly connected to the top of the movable blocks, a pressure block slidably connected to the surface of the locking block, the bottom of the pressure block contacting the top of the movable block, a pawl movably connected to the top of the pressure block, a stop block slidably connected to the inner wall of the pawl, the bottom of the stop block fixedly connected to the top of the pressure block, bolts provided inside the pawl and the pressure block, the bottom of the bolts penetrating the bottom of the pressure block and extending into the interior of the movable block, the inner walls of the movable block, the pressure block and their pawl being threadedly connected to the surface of the bolts, a gear meshing on the inner side of the pawl, a gear ring movably connected to the outer side of the pressure block, and a quick-release mechanism provided on the top of the base.

[0008] As a preferred embodiment of this utility model, the quick-release mechanism includes a support ring disposed on the top of the base. Multiple fixing blocks are fixedly connected to the bottom of the support ring. Each fixing block has a slidably connected locking plate on its inner wall. A spring is fixedly connected to the surface of the locking plate. The end of the spring away from the locking plate is fixedly connected to the inner wall of the fixing block. The side of the locking plate near the locking claw engages with the inside of the locking claw. When the support ring is moved upward, the locking plate can move the locking claw synchronously. A linkage component is disposed on the top of the base.

[0009] As a preferred embodiment of this utility model, the linkage component includes a support plate fixedly connected to the inner side of the fixed block. The inner wall of the support plate is movably connected to a rotating wheel via a bearing. Multiple steel wire ropes are fixedly connected to the surface of the rotating wheel. The end of the steel wire rope away from the rotating wheel extends into the interior of the fixed block and is fixedly connected to the surface of the clamping plate. When the rotating wheel is rotated, the clamping plate can be pulled away from the interior of the clamping claw by the steel wire rope.

[0010] As a preferred embodiment of this invention, a knob is fixedly connected to the top of the rotating wheel, which allows the rotating wheel to be rotated more quickly and conveniently.

[0011] As a preferred embodiment of this invention, handles are fixedly connected to both the left and right sides of the top of the support ring, which makes it easier for the fingers to grip and for the support ring to move.

[0012] As a preferred embodiment of this utility model, the bottom of each card plate is provided with an angle, which enables the bottom of the card plate to automatically retract into the interior of the fixing block when it is squeezed.

[0014] 1. When this utility model is used, under the action of the clamping structure, quick release mechanism and linkage component, the gear can be stably clamped and the chuck can be quickly installed and disassembled. This avoids the inconvenience of replacing and picking up the chuck one by one and the instability of the clamping of the universal chuck, thus giving it the advantage of being easy to use.

[0015] 2. This utility model features a quick-release mechanism, including a support ring, a fixing block, a locking plate, and a spring. This design allows for quick and easy disassembly of clamped items, improving work efficiency. The locking plate automatically engages with the jaws under the action of the spring, ensuring a stable connection. Furthermore, the quick-release mechanism makes operation simpler and faster.

Each fixing block 11 has a sliding plate 12 connected to its inner wall. A spring 13 is fixedly connected to the surface of the plate 12. The end of the spring 13 away from the plate 12 is fixedly connected to the inner wall of the fixing block 11. The side of the plate 12 near the claw 5 is inserted into the inside of the claw 5. When the support ring 10 is moved upward, the claw 5 can be moved synchronously through the plate 12. A linkage component is set on the top of the base 1.

[0025] As a technical optimization of this utility model, a quick-release mechanism is provided, including a support ring 10, a fixing block 11, a locking plate 12, and a spring 13. This design enables quick and convenient disassembly of clamped items, improving work efficiency. The locking plate 12 automatically engages with the claw 5 under the action of the spring 13, ensuring a stable connection. Simultaneously, the quick-release mechanism design makes operation simpler and faster.

[0026] refer to Figure 4 The linkage component includes a support plate 14 fixedly connected to the inside of the fixed block 11. The inner wall of the support plate 14 is movably connected to a rotating wheel 15 via a bearing. Multiple steel wire ropes 16 are fixedly connected to the surface of the rotating wheel 15. One end of the steel wire rope 16 away from the rotating wheel 15 extends into the interior of the fixed block 11 and is fixedly connected to the surface of the clamping plate 12. When the rotating wheel 15 is rotated, the clamping plate 12 can be pulled away from the interior of the clamping claw 5 by the steel wire rope 16.

[0027] As a technical optimization of this utility model, a linkage component is provided, including a support plate 14, a rotating wheel 15, and a steel wire rope 16.

The angle 19 design improves the smoothness and reliability of disassembly, further enhancing the user experience of the device.

[0034] The working principle and usage of this utility model are as follows: This device mainly consists of a base 1, a movable block 2, a clamping structure, and a quick-release mechanism. During operation, the item to be clamped is first placed on the base 1 and fixed by the clamping structure. The clamping structure clamps the item through the coordinated action of a locking block 3, a pressure block 4, and a jaw 5. The pressure block 4 slides on the locking block 3 and is fixedly connected to the movable block 2 and the jaw 5 by bolts 7, ensuring clamping stability. A stop block 6 is provided on the inner wall of the jaw 5 to further enhance clamping stability. When it is necessary to quickly remove the clamped item, the quick-release mechanism is used. The quick-release mechanism includes a support ring 10, a fixing block 11, a locking plate 12, and a spring 13. The locking plate 12 is engaged with the inside of the jaw 5 under the action of the spring 13, achieving a stable connection. When disassembly is required, the locking plate 12 is pulled away from the inside of the jaw 5 by the rotating wheel 15 and the wire rope 16 in the linkage assembly, thereby releasing the clamped item. The design of the support ring 10 and handle 18 makes operation more convenient. The overall structure is more stable through the precise meshing of the jaws 5 and gear 8, preventing loosening or misalignment. The jaws 5 can be quickly replaced depending on the gear 8 being processed (using a quick-release mechanism to simultaneously pick up and place three jaws 5 on the pressure block 4 for installation or removal). The outer side of the pressure block 4 can also clamp the gear ring 9 for processing. This avoids the inconvenience of replacing and picking up the jaws 5 one by one and the instability of the universal jaws 5, giving it the advantage of ease of use.

[0035] In summary, when this utility model is used, under the action of the clamping structure, quick-release mechanism and linkage components, it can stably clamp the gear 8 and quickly install and remove the chuck 5, avoiding the inconvenience of replacing and removing the chuck 5 one by one and the instability of the clamping of the universal chuck 5, thus giving it the advantage of being easy to use and solving the problems of unstable clamping and inconvenient disassembly.
