Description

Technical Field

[0001] This utility model relates to the field of gear hardness testing equipment technology, and in particular to a high-hardness gear locking device. Background Technology

[0002] A high-hardness gear locking device is a mechanical device used to restrict the movement of gears, keep them stationary in a specific position, and prevent them from rotating accidentally. The device is made of high-hardness material to ensure that it can maintain a stable locked state even when subjected to large external forces and torques. Gears are key components in mechanical transmission systems, and their hardness and wear resistance directly affect the performance and lifespan of the entire system. However, during the gear hardening process, the lack of a positioning and locking mechanism during rotation can lead to gear misalignment or vibration, affecting the machining accuracy.

[0003] A search revealed Chinese Patent Publication No. CN217728498U, which discloses a gear hardness treatment processing device, belonging to the field of gear hardness treatment and testing technology. Its features include a fixed base frame and a clamping device for fixing and moving the gear. A fixed support column is connected to the rear of the upper surface of the fixed base frame. A rotatable rotating plate is inserted into the upper surface of the fixed support column. Support devices are connected to the left and right sides of the rotating plate. Each support device has a clamping device slidably inserted into its side surface. A fixing bolt is inserted into the side surface of the clamping device, and a locking nut is inserted into the side surface of the fixing bolt. The device allows workers to quickly and easily fix gears to the fixture, and can fix gears of different thicknesses. However, existing high-hardness gear locking devices lack a positioning and locking mechanism during rotation to ensure the strength and rigidity of the locking device, leading to gear misalignment and vibration, angular positioning deviations, and affecting processing accuracy, thus limiting the final processing results. Utility Model Content

The fixing mechanism 2 is used to fix the locking device. A throttle 16 is fixedly connected to the outer wall of the adjusting block 14. A slide groove 17 is slidably connected to the right side of the inner wall of the support rod 5.

[0040] Specifically, this high-hardness gear locking device uses a support frame 1 as its basic framework. The height of the entire device is adjusted by sliding the lifting rod 3 on the inner wall of the support frame 1, adapting to gears of different heights. The movable frame 4 on the left lifting rod 3 and the support rod 5 on the right lifting rod 3 can be rotated at multiple angles to adjust their positions, facilitating gear alignment. Rotating the threaded rod 6, its rotational connection with the liquid damper 7 allows for fine-tuning of the distance. The liquid damper 7 buffers the impact force during locking, ensuring stability. Rotating the movable ring 10, due to its threaded connection with the liquid damper 7, drives the telescopic frame 11 to extend or retract, causing the fixed plate 12 and clamping ring 13 to move closer to or further away from the gear, achieving precise clamping and locking of the gear. The adjusting block 14 on the threaded column 8 can be finely adjusted to ensure proper clamping. With accurate positioning, the device is finally secured by tightening the fixing block 15 onto the threaded rod 6 to prevent loosening, thus achieving reliable locking of the high-hardness gear. The support frame 1 provides a stable mounting base for the locking device through the top fixing mechanism 2, ensuring that it remains in a fixed position during operation and meeting the locking requirements of various equipment. The handles 16 around the adjusting block 14 facilitate manual operation by the operator. By rotating the handles 16, the adjusting block 14 can be operated accordingly to adjust the relevant parameters of the equipment or the position of the components. The slide groove 17 on the right side of the inner wall of the support rod 5 provides guidance and movement space for the components that are slidably connected to it, allowing the components to slide smoothly within the track defined by the slide groove 17, achieving flexible position movement to adapt to the usage requirements in different working scenarios.

[0041] Reference Figure 1 , Figure 2 and Figure 5 The fixing mechanism 2 includes a connecting frame 201, which is fixedly connected to the top of the outer wall of the support frame 1. The outer walls of the two connecting frames 201 are fixedly connected to a fixing block 202 on the side away from each other. An adjusting rod 203 is rotatably connected to one side of the outer wall of the fixing block 202. A fixing buckle 204 is rotatably connected to the middle of the outer wall of the adjusting rod 203. A fixing column 205 is rotatably connected to the other end of the fixing buckle 204. The fixing column 205 is slidably connected to the top of the inner wall of the fixing block 202. An adjusting frame 206 is rotatably connected to the top of the outer wall of the lifting rod 3. Insertion holes 18 are equidistantly opened on the outer wall of the lifting rod 3. A pin 19 passes through the inner side of the top of the insertion hole 18. A connecting plate 20 is fixedly connected to the front and rear sides of the bottom of the support frame 1. Bolts 21 are threadedly connected to the left and right sides of the outer wall of the connecting plate 20.

[0042] Specifically, the fixing mechanism 2, based on the connecting frame 201, is firmly installed on the top of the support frame 1, providing stable support for the entire mechanism. When it is necessary to fix the target object, the adjusting rod 203 is rotated. Since the adjusting rod 203 is rotatably connected to the fixing block 202, its rotation will drive the fixing buckle 204, which is rotatably connected in the middle, to move. The other end of the fixing buckle 204 is rotatably connected to the fixing column 205, and the fixing column 205 can slide on the top of the inner wall of the fixing block 202. This allows the fixing buckle 204 to flexibly adjust its opening and closing angle and position. Through the linkage of the adjusting rod 203, the fixing buckle 204, and the fixing column 205, objects of different shapes and sizes can be tightly fitted and firmly fixed. At the same time, the lifting rod 3... The adjustable bracket 206, which is rotatably connected, can be adjusted in angle according to actual needs. It works in conjunction with the fixing mechanism 2 to further optimize the fixing effect and improve the applicability and reliability of the entire device for fixing objects under various working conditions. The lifting rod 3 can be adjusted in height by using the insertion holes 18 and pins 19 that are equidistantly opened on the outer wall. By inserting the pins 19 into the insertion holes 18 at different positions, the lifting rod 3 can be fixed at the corresponding height to meet the needs of different usage scenarios. The connecting plates 20 on the front and rear sides of the bottom of the support frame 1 can be stably connected to other components or the base by the bolts 21 that are threaded on the left and right sides, ensuring the stability of the overall structure composed of the support frame 1 and the lifting rod 3, so that the lifting rod 3 can still maintain reliable support after the height is adjusted.

[0043] Reference Figure 1 , Figure 2 and Figure 3 A handle 22 is fixedly connected to the front side of the outer wall of the support frame 1. The upper and lower ends of the outer wall of the handle 22 are provided with connection holes 23. Support rods 24 are fixedly connected to the left and right sides of the outer wall of the support frame 1. Bolts 25 are threaded to the front and rear ends of the outer wall of the support rods 24. Screws 26 are threaded to the top of the inner wall of the adjustment frame 206. Nuts 27 are threaded to the front side of the outer wall of the screws 26.

[0044] Specifically, the handle 22 fixed on the front of the support frame 1 facilitates the operator's gripping and movement, and the connection holes 23 at its upper and lower ends can be used to connect and expand with other components, enhancing the flexibility of equipment combination; the support rods 24 on the left and right sides of the support frame 1 can be stably connected and fixed to external equipment or structures through the bolts 25 at the front and rear ends of the outer wall, ensuring the stability of the overall support structure; the screw 26 threaded on the top of the inner wall of the adjustment frame 206 can be adjusted by rotating its extension length, and tightened with the nut 27 on the front of the screw 26, thereby realizing the adjustment of the height, position or angle of related components of the adjustment frame 206 to meet the usage needs in different working scenarios.

[0045] Working Principle: By sliding the lifting rod 3 along the inner wall of the support frame 1, the vertical height of the entire device can be adjusted to accommodate gear installations at different heights. Simultaneously, the movable frame 4, rotatably connected to the top of the left lifting rod 3, and the support rod 5, rotatably connected to the top of the right lifting rod 3, can rotate around their connection points. Combined with the height adjustment of the lifting rod 3, the positions of components such as the threaded rod 6 and the liquid damper 7 can be adjusted, allowing the device to better align with the gear to be locked. One end of the threaded rod 6 is rotatably connected to the liquid damper 7. When the device is subjected to external impact or vibrates during locking, the liquid damper 7 utilizes the flow of its internal liquid to dissipate energy, providing damping and buffering effects, reducing damage to the device and gears from vibration, and improving the stability and reliability of locking. The liquid damper 7 is connected to the telescopic frame 11 via the threaded column 8, the fixed ring 9, and the movable ring 10, at the pivot of the fixed support column. A liquid damper 7 is added, which automatically locks after being rotated to the correct position to prevent shaking. Rotating the moving ring 10 allows it to move along the threaded outer wall of the liquid damper 7, thereby pushing or pulling the telescopic frame 11. The telescopic movement of the telescopic frame 11 drives the fixed plates 12 and clamping rings 13 at both ends to move, realizing the clamping or releasing action of the gear. When it is necessary to lock the gear, the telescopic frame 11 is extended by adjusting the moving ring 10, which drives the clamping rings 13 to clamp the gear. When unlocking, the opposite operation is performed to release the clamping rings 13. The adjusting block 14 on the threaded column 8 can be used for some fine adjustments to the entire device. For example, during installation or locking, the position of the liquid damper 7 and related components can be finely adjusted by rotating the adjusting block 14 to achieve a more precise locking effect. In addition, the fixed block 15 threaded to the threaded rod 6 can fix the threaded rod 6 after it is adjusted to the appropriate position to prevent the threaded rod 6 from rotating accidentally and affecting the locking state of the device.

[0046] The fixing mechanism 2 is based on the connecting frame 201 and is fixed to the top of the support frame 1 to achieve stable support. The fixing block 202 on the outer side of the two connecting frames 201 provides a fulcrum for the adjustment rod 203. When the adjustment rod 203 is rotated, it drives the fixing buckle 204 connected in the middle to move. The other end of the fixing buckle 204 is rotatably connected to the fixing column 205, so that the fixing column 205 can slide on the top of the inner wall of the fixing block 202, thereby changing the opening degree and position of the fixing buckle 204. It can fix locking devices of different specifications. At the same time, the adjusting frame 206 rotatably connected to the top of the lifting rod 3 can be rotated to adjust the angle. Together with the fixing mechanism 2, it meets the needs of fixing and adjusting the locking device in different working scenarios, and improves the applicability and flexibility of the equipment.
