Description

Technical Field

[0001] This utility model relates to the technical field of internal gear ring processing devices, specifically a clamping device for internal gear ring processing. Background Technology

[0002] The clamping device for internal gear ring machining plays a crucial role in the efficient and high-precision machining of internal gear rings. This device mainly consists of a base, chuck, positioning blocks, and clamping mechanism. The base provides stable support, and the chuck, typically employing a three- or four-jaw structure, has its jaws tightly fitted against the outer wall of the internal gear ring, enabling automatic centering and ensuring the accurate horizontal position of the internal gear ring. The positioning blocks are designed according to the shape and size of the internal gear ring, precisely determining its axial position and preventing axial movement during machining. The clamping mechanism provides strong clamping force through hydraulic, pneumatic, or mechanical lead screws, firmly fixing the internal gear ring to the worktable. For example, during gear milling, this stable clamping can withstand the impact of cutting forces, ensuring that the internal gear ring does not shift or vibrate during machining, thereby achieving precise machining of the tooth profile. This effectively improves the machining accuracy and surface quality of the internal gear ring, meeting the stringent requirements of various mechanical equipment, and is of great significance in the field of mechanical manufacturing.

[0003] However, in the existing technology, when clamping internal gear rings, multi-jaw mechanisms are mostly used for clamping. The driving force is provided by hydraulic, pneumatic or mechanical screws to adjust each jaw face. This results in slow clamping speed, and the adjustment of multiple jaw faces will cause deviations in the clamping force of different jaw faces, which will affect the processing of internal gear rings.

[0004] In response to the aforementioned technologies, a clamping device for machining internal gear rings is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a clamping device for machining internal gear rings. By using this device, the problems of slow clamping speed and deviations in clamping force caused by adjusting multiple jaw surfaces in the above-mentioned background technology are solved.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a clamping device for machining internal gear rings, comprising a support platform and a clamping mechanism mounted on the support platform. A workpiece is placed on the support platform. The clamping mechanism includes a driving component and a transmission gear meshing with the driving component. Both the driving component and the transmission gear are located inside the support platform. Multiple transmission gears are provided, and a central column is installed in the middle of each transmission gear. Clamping teeth are installed at the upper end of the central column. The driving component can simultaneously drive multiple transmission gears to rotate, causing the transmission gears to drive the central column to rotate and causing the lower sides of multiple clamping teeth to simultaneously press against the upper side of the workpiece, thereby clamping the workpiece.

[0007] Preferably, the driving component includes a motor and a driving gear mounted on the driving end of the motor. The driving gear meshes with a transmission gear, and the bottom of the motor is mounted on the inner side of the support platform.

[0008] Preferably, the lower end of the clamping tooth is composed of a flat end and an inclined end, with the inclined end located on one side of the flat end.

[0009] Preferably, a floating disk is installed at the upper end of the support platform, the floating disk matches the groove opened at the upper end of the support platform, and a reset mechanism is installed at the lower end of the floating disk, the reset mechanism is installed on the inner side of the support platform.

[0010] Preferably, a slot is provided on the support platform located inside the groove, and a reset mechanism is installed inside the slot. The reset mechanism consists of a pressure plate and a reset spring. The upper end of the reset spring is fixedly installed on the lower end of the pressure plate, and the lower end of the reset spring is fixedly installed inside the slot.

[0011] Preferably, the central column extends upward from the inside of the support platform through the support platform and outward, and the length of the portion extending outward from the support platform is greater than the thickness of the workpiece.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This utility model proposes a clamping device for machining internal gear rings. When the workpiece is placed on a floating plate, the motor drives the drive gear to rotate. The drive gear can synchronously drive multiple transmission gears to rotate. At this time, the transmission gears drive the central column to rotate and cause the inclined end of the clamping teeth to contact the workpiece. Due to the squeezing force, the workpiece moves down until the flat end contacts the workpiece, thus completing the clamping of the workpiece. This allows multiple clamping teeth to clamp the workpiece synchronously, reducing operational losses and eliminating deviations in the clamping force of individual clamping teeth.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0022] Combination Figure 1 A clamping device for machining an internal gear ring consists of a support platform 1 and a clamping mechanism. The workpiece 8 is fixed by placing it on the support platform 1 and then clamping it with the clamping mechanism. The workpiece 8 can be an internal gear ring or a similar annular structure, preferably an internal gear ring.

[0023] Combination Figure 1-Figure 2 The clamping mechanism includes a drive component and a transmission gear 4 meshing with the drive component. Both the drive component and the transmission gear 4 are located inside the support platform 1. There are multiple transmission gears 4, and a central column 5 is installed in the middle of each transmission gear 4. The central column 5 extends upward from the inside of the support platform 1 through the support platform 1 and extends outward. The length of the part extending outward from the support platform 1 is slightly greater than the thickness of the workpiece 8. A clamping tooth 6 is installed at the upper end of the central column 5. The drive component can drive multiple transmission gears 4 to rotate simultaneously, so that the transmission gear 4 drives the central column 5 to rotate and causes the lower side of the clamping tooth 6 to press against the upper side of the workpiece 8.

[0024] Furthermore, in combination Figure 2 The driving component includes a motor 2 and a drive gear 3 installed on the drive end of the motor 2. The drive gear 3 is meshed with a transmission gear 4. The bottom of the motor 2 is installed on the inner side of the support platform 1. The motor 2 drives the drive gear 3 to rotate, and the drive gear 3 can synchronously drive multiple transmission gears 4 to rotate.

[0025] Combination Figures 3-4A floating disk 7 is installed on the upper end of the support platform 1. The floating disk 7 matches the groove 11 opened on the upper end of the support platform 1. A reset mechanism is installed on the lower end of the floating disk 7. The reset mechanism is installed on the inner side of the support platform 1. Furthermore, in the initial state, the upper surface of the floating disk 7 is slightly lower than the upper surface of the support platform 1, which makes it easier to place the workpiece 8 on the floating disk 7 and have it clamped by the support platform 1. When the clamping teeth 6 squeeze the floating disk 7, the reset mechanism will squeeze, eventually causing the clamping teeth 6 and the floating disk 7 to clamp the workpiece 8.

[0026] Furthermore, in combination Figures 2-5 The lower end of the clamping tooth 6 is composed of a flat end 61 and an inclined end 62. The inclined end 62 is located on one side of the flat end 61. When the workpiece 8 is placed on the floating disk 7, the motor 2 drives the drive gear 3 to rotate. The drive gear 3 can synchronously drive multiple transmission gears 4 to rotate. At this time, the transmission gears 4 drive the central column 5 to rotate and cause the inclined end 62 of the clamping tooth 6 to contact the workpiece 8. At this time, due to the squeezing force, the workpiece 8 moves down until the flat end 61 contacts the workpiece 8, thus completing the clamping of the workpiece 8.

[0027] Furthermore, combining Figure 4 A slot 12 is provided on the support platform 1 located inside the groove 11. The reset mechanism is installed inside the slot 12. The reset mechanism consists of a pressure plate 71 and a reset spring 72. The upper end of the reset spring 72 is fixedly installed on the lower end of the pressure plate 71 and the lower end of the reset spring 72 is fixedly installed inside the slot 12. The pressure plate 71 is inserted into the slot 12. When the floating disk 7 is squeezed by the workpiece 8, the pressure plate 71 moves down and squeezes the reset spring 72. When the workpiece 8 is removed, the pressure plate 71 resets under the force of the reset spring 72.
