Description

Technical Field

[0001] This utility model relates to the technical field of hardness testing devices, and in particular to a hardness testing device for gear processing. Background Technology

[0002] In the field of mechanical manufacturing, gears are a crucial transmission component. The hardness of gears directly affects their wear resistance, fatigue resistance, and service life. Therefore, accurately measuring the hardness of gears is of vital importance for ensuring the normal operation and stable performance of mechanical equipment.

[0003] Traditional gear hardness testing devices typically use a fixed clamp to hold the gears. The dimensions of this clamp are pre-set and can only accommodate gears within a specific size range. When testing gears of different sizes, the entire clamp must be replaced, making the process cumbersome, increasing testing costs, and significantly reducing testing efficiency.

[0004] Furthermore, traditional gear hardness testing devices cannot be easily adjusted in angle once clamped and fixed during the testing process. Operators need to constantly disassemble and reassemble the device to change different testing angles, which is quite cumbersome. This is especially true for gears with complex shapes or special tooth profiles, where manually adjusting the testing position is even more difficult, resulting in low testing efficiency.

An impact component 8 is installed at the head of the equipment lifting box 7. The impact component 8 is located directly above the detachable clamping seat 3. By vertically installing several sets of metal seats 2 on the upper surface of the testing table 1, it is convenient to install detachable clamping seats 3 through the metal seats 2 during testing. The detachable clamping seats 3 are fitted onto the metal seats 2 and fixed with bolts. This detachable connection method makes it easy to install and remove the detachable clamping seats 3, and facilitates the replacement of different specifications of detachable clamping seats 3 according to different testing needs, improving the versatility and flexibility of the device. Furthermore, the rotating clamping plate 4 and the adjustable clamping plate 5 enable stable clamping of gears of different sizes by rotating the rotating clamping plate 4 and moving the adjustable clamping plate 5. The rotation of the rotating clamping plate 4 can adjust the testing position of the gear, making the testing more comprehensive and accurate.

[0024] Reference Figure 4 and Figure 5 The detachable clamping base 3 includes a housing portion 31 and a left ear plate 32 and a right ear plate 33 for mounting the rotating clamping plate 4 and the adjustable clamping plate 5, respectively. The left ear plate 32 and the right ear plate 33 are vertically mounted on both sides of the upper end face of the housing portion 31, and the housing portion 31, the left ear plate 32, and the right ear plate 33 are integrally formed. By designing the detachable clamping base 3 with a structure in which the left ear plate 32 and the right ear plate 33 of the housing portion 31 cooperate, it can be stably mounted on the metal base 2 through the housing portion 31 during installation. The setting of the left ear plate 32 and the right ear plate 33 ensures that the rotating clamping plate 4 and the adjustable clamping plate 5 are installed relative to each other, and the adjustable clamping plate 5 is threadedly connected to the right ear plate 33, which facilitates the adjustment of the distance between the rotating clamping plate 4 and the adjustable clamping plate 5.

The drive shaft 42 is rotatably mounted on the left ear plate 32, and the fixed chuck 41 and the driven gear 43 are fixedly mounted at both ends of the drive shaft 42. By designing the rotating chuck 4 with a structure in which the fixed chuck 41, drive shaft 42, and driven gear 43 cooperate, it is ensured that the fixed chuck 41 can be driven to rotate synchronously through the drive shaft 42 during use. After the gear is clamped by the fixed chuck 41, the gear can be driven to adjust the angle. The driven gear 43 is designed to cooperate with the drive component 6, facilitating the rotation and adjustment of the rotating chuck 4 by the drive component 6.

[0026] Reference Figure 4 and Figure 5 The adjustable chuck 5 includes a movable chuck 51, a transverse screw 52, ​​and an operating tail plate 53.

The movable chuck 51 is rotatably mounted on the head of the transverse screw 52, ​​and the operating tail plate 53 is fixedly mounted on the tail of the transverse screw 52. By designing the adjustable chuck 5 with a structure in which the movable chuck 51, the transverse screw 52, ​​and the operating tail plate 53 cooperate, it is ensured that the transverse screw 52 can be rotated by operating the tail plate 53 during use. This, in turn, allows the movable chuck 51 to be driven closer to or further away from the fixed chuck 41 through the threaded engagement between the transverse screw 52 and the right ear plate 33, thus achieving rapid gear clamping. A central protrusion 411 is fixedly installed at the center of the inner surface of the fixed chuck 41 and the movable chuck 51. The central protrusion 411 is used to clamp the gear in the central hole. The central protrusion 411 on the inner side of the fixed chuck 41 and the movable chuck 51 can be accurately clamped in the central hole of the gear, ensuring the stability of the gear during the testing process, avoiding gear shaking and deviation, and improving the reliability of the test results.

The drive motor 61 is fixedly mounted on a right-angle base 312, and the drive gear 62 is fixedly mounted on the output end of the drive motor 61. A protective cover 313 is also installed on the right-angle base 312. The driving component 6 drives the drive gear 62 to rotate via the drive motor 61, which in turn drives the driven gear 43 and the rotating chuck 4 to rotate, realizing automatic adjustment of the gear detection position and improving detection efficiency and accuracy. The protective cover 313 protects the driving component 6 from external dust and debris, extending its service life and improving operator safety.

[0028] Reference Figure 1 and Figure 2The impact assembly 8 includes an electric cylinder 81 and an impact block 82. The electric cylinder 81 is vertically fixed to the head of the equipment housing 7, and the impact block 82 is fixedly installed at the output end of the electric cylinder 81. The electric cylinder 81 of the impact assembly 8 drives the impact block 82 to move rapidly downward to perform an impact test on the gear, which can simulate the deformation of the gear under force and accurately detect the hardness of the gear.

[0029] In this embodiment, during the inspection process, a detachable clamping base 3 is fitted onto a metal base 2, and the two are then fixed together with bolts. The gear to be tested is then placed between a fixed clamping plate 41 and a movable clamping plate 51. The transverse screw 52 is rotated by operating the tailstock 53, which in turn pushes the movable clamping plate 51 to clamp the gear. The gear is stably clamped and fixed by the central protrusions 411 at both ends. This allows the electric cylinder 81 to be activated to drive the impact block 82 to move down quickly, achieving the purpose of impact testing on the gear. After impacting the same position once or multiple times, the drive motor 61 is activated. The drive gear 62 on the drive motor 61 drives the driven gear 43 to rotate, thereby rotating the gear under test to adjust the impact position. The gear hardness is determined by observing the gear deformation.
