Description

Technical Field

[0001] This utility model relates to the field of gear shaft processing technology, specifically a clamping device for processing planetary reducer gear shafts. Background Technology

[0002] A gear shaft is a mechanical part that supports rotating parts and rotates with them to transmit motion, torque, or bending moment. The planetary gears in a reducer require corresponding gear shafts for installation. Before installation, the gear shaft needs to be ground. It is generally a metal rod, and each section can have a different diameter. The rotating parts in the machine are mounted on the shaft, and the gear shaft needs to be ground by a grinding device during processing.

[0003] For example, Chinese patent application number 202311246939.1 describes a new type of gear shaft grinding device for planetary reducer production. This patent uses a positioning component to activate a drive motor when the gear shaft passes the second guide roller and the first guide roller, causing the first guide roller to rotate and thus drive the gear shaft to one side. This effectively enables the gear shaft to be accurately positioned and driven on the processing table.

[0004] However, the clamping devices of the aforementioned patents can often only fix and clamp specific types of gear shafts, which limits their use and seriously affects their applicability and practicality. Utility Model Content

The two sides inside the mounting base 3 are movably connected to clamping blocks 4 through guide components. The bottom of the two clamping blocks 4 are provided with clamping mechanisms.

[0032] By adopting the above technical solution, this device can quickly clamp and fix the gear shaft, thereby preventing the gear shaft from deflecting during processing and greatly improving the processing quality of this device.

[0033] In the embodiments of this application, such as Figure 1 and Figure 4 As shown, the adjustment mechanism includes a motor 6 installed on one side of the workbench 1. The output end of the motor 6 is fixedly connected to a positive and negative lead screw 7. Both ends of the positive and negative lead screw 7 are movably connected to lead screw nuts 8. The top of the lead screw nuts 8 extends to the top of the workbench 1 through a sliding groove 9 and is fixedly connected to the fixing plate 2.

[0034] By adopting the above technical solution, the position of the left and right mounting seats 3 can be quickly adjusted through the adjustment mechanism, so that the device can clamp and fix gear shafts of different lengths according to actual needs, thereby further improving the applicability and practicality of the device.

[0035] In the embodiments of this application, such as Figure 2-3 As shown, the clamping mechanism includes slots 12 formed on opposite sides of the two clamping blocks 4 and an electric push rod 10 mounted on the top of the fixed plate 2. Limiting grooves 13 are formed on both inner walls of the slots 12. A trapezoidal slider 11 is fixedly connected to the output end of the electric push rod 10. The two sides of the trapezoidal slider 11 extend into the interior of the two slots 12 and are fixedly connected to limiting blocks 14. The limiting blocks 14 are slidably connected to the limiting grooves 13.

[0036] By adopting the above technical solution, this device can quickly clamp and fix gear shafts of different models through the clamping mechanism, thereby enabling the device to process gear shafts of different models, which greatly improves the applicability and processing efficiency of the device.

[0037] In the embodiments of this application, such as Figure 2-3 As shown, the guide assembly includes guide grooves 15 formed on the inner walls of both sides of the inner cavity of the mounting base 3. A guide block 16 is movably connected inside the guide groove 15, and the other end of the guide block 16 is fixedly connected to the clamping block 4.

[0038] By adopting the above technical solution and utilizing the guiding effect of the guiding component, the clamping block 4 can move more stably.

[0039] In the embodiments of this application, such as Figure 3 As shown, V-shaped grooves 5 are provided on the opposite sides of the two clamping blocks 4.

[0040] By adopting the above technical solution, the clamping effect of the clamping block 4 is improved by utilizing the V-groove 5.

[0041] In the embodiments of this application, such as Figure 4 As shown, the inner diameter of the groove 9 is matched with the width of the lead screw nut 8.

[0042] By adopting the above technical solution, the limiting effect of the slide 9 is improved.

[0046] By adopting the above technical solution, the controller 17 can more conveniently control the electrical components inside the device.

[0047] In use, the operator first adjusts the position of the fixed plate 2 according to actual needs. During adjustment, the operator can start the motor 6 through the controller 17, so that the motor 6 can drive the positive and negative lead screws 7 to rotate. When the positive and negative lead screws 7 rotate, they will drive the lead screw nuts 8 at both ends to slide towards each other under the limiting action of the slide groove 9. Thus, the two lead screw nuts 8 can drive the two fixed plates 2 to move towards each other, so that the fixed plates 2 can be quickly moved to the appropriate position according to actual needs. After the position of the fixed plate 2 is adjusted, the operator places the gear shaft at the center of the mounting base 3. Then, the operator starts the electric push rod 10 through the controller 17, so that it drives the trapezoidal slider 11 to slide down along the slot 12. Thus, the clamping block 4 can move towards each other under the limiting action of the limiting groove 13 and the limiting block 14, so that the gear shaft can be quickly clamped and fixed. This allows the device to process gear shafts of different models, thus greatly improving the applicability and processing efficiency of the device.
