Description

Technical Field

[0001] This utility model specifically relates to a fixing fixture for rough machining of gearbox screw plugs. Background Technology

[0002] A gearbox, also known as a gear transmission box or gear reducer, is a mechanical device used to transmit power and motion. It achieves the conversion of speed and torque through the meshing of gears. The screw plug inside the gearbox is an important component of the gearbox design, mainly responsible for sealing, draining oil, and maintenance.

[0003] Currently, during the processing of screw plugs, the outer surface of the screw plug is usually ground or the inside is drilled. During such processing, a certain amount of vibration is generated, which affects the processing accuracy and results in poor processing effect. Utility Model Content

[0006] The adjustment component is driven by a power unit to rotate the gripper limit plate and adjust the machining direction of the screw plug.

[0007] Preferably, the support base has a cavity, the direction adjustment component includes a first gear disposed in the cavity, a fixing plate is disposed on the surface of the first gear, and the gripper limiting plate is mounted on the surface of the fixing plate.

[0008] Preferably, the frame surface has a groove, and a second gear is disposed in the groove, the second gear meshing with the first gear.

[0009] Preferably, the power unit includes a motor disposed on the lower surface of the frame, the power output end of the motor extends into the housing and is connected to a worm gear, and a worm wheel adapted to the worm gear is also disposed in the housing.

[0010] Preferably, a rotating shaft is inserted into the worm gear, and the rotating shaft extends outside the housing and connects to the second gear.

[0011] Preferably, the support base is further provided with a rotating roller for supporting and cooperating with the first gear.

[0012] Preferably, the surface of the gripper limiting plate is provided with a limiting groove for inserting a screw plug, and three limiting grippers are provided at equal intervals around the outer side of the limiting groove.

[0013] The technical effects and advantages of this utility model are as follows: This fixture for rough machining of gearbox plugs inserts the plug to be machined into the limiting groove, adjusts the position of the limiting jaws to limit and fix the root of the plug, improving the stability during machining. After machining one side, the motor is started, and the motor's power output drives the worm to rotate. Through the meshing of the worm and the worm wheel, the worm wheel rotates, which in turn drives the rotating shaft to rotate, causing the second gear to rotate in the groove. Through the meshing of the second gear and the first gear, the second gear rotates, causing the first gear to rotate, which in turn drives the rotating roller to drive the jaw limiting disc to rotate, thus rotating the plug to the side to be machined. No manual operation is required, improving the convenience of the machining process. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] To facilitate improved stability during bolt processing, refer to Figure 1 , Figure 2 and Figure 3As shown, the machine includes a frame 1, on which a support base 2 is provided. A gripper limiting disk 3 for fixing the screw plug to be processed is installed on the surface of the support base 2. A direction adjustment component for driving the gripper limiting disk 3 to rotate is provided on the lower surface of the frame 1. The adjustment component is driven by a power unit to rotate the gripper limiting disk 3, thereby adjusting the processing direction of the screw plug. The screw plug to be processed is inserted into the limiting groove 14, and the position of the limiting gripper 15 is adjusted to limit and fix the root of the screw plug, improving the stability during the processing. After processing one side, the motor 8 is started. The power output end of the motor 8 drives the worm gear 10 to rotate. The worm gear 10 meshes with the worm wheel 11, driving the worm wheel 11 to rotate, which in turn drives the rotating shaft 12 to rotate, causing the second gear 7 to rotate in the groove 6. The second gear 7 meshes with the first gear 4, driving the first gear 4 to rotate, which in turn drives the rotating roller 13 to drive the gripper limiting disk 3 to rotate, thus rotating the screw plug to the side to be processed without manual operation.

[0023] To facilitate adjustment of the screw plug's orientation for machining, refer to... Figure 1 , Figure 2 , Figure 3 ,picture, Figure 5 and Figure 6 As shown, the support base 2 has a cavity. The direction adjustment assembly includes a first gear 4 disposed within the cavity. A fixing plate 5 is disposed on the surface of the first gear 4. The gripper limiting plate 3 is mounted on the surface of the fixing plate 5. The cavity facilitates the rotation of the first gear 4, and a rotating roller 13 supports the first gear 4 and cooperates with its rotation. The frame 1 has a groove 6 on its surface. A second gear 7 is disposed within the groove 6. The second gear 7 meshes with the first gear 4. A rotating rod that cooperates with the second gear 7 is disposed within the groove 6, supporting the second gear 7 and adapting to its rotation. The rotation of the second gear 7 meshes with the first gear 4 to cooperate with its rotation. The power unit includes a motor 8 mounted on the lower surface of the frame 1. The power output end of the motor 8 extends into the housing 9 and is connected to a worm gear 10. A worm wheel 11, adapted to the worm gear 10, is also located inside the housing 9. Through the adaptation of the worm gear 10 and the worm wheel 11, the rotation of the worm gear 10 drives the worm wheel 11 to rotate, which in turn drives the rotation of the rotating shaft 12. The rotating shaft 12 is inserted into the worm wheel 11 and extends outside the housing 9 to connect with a second gear 7, ultimately driving the second gear 7 to rotate within the groove 6. The support base 2 also includes a roller 13 for supporting and engaging the first gear 4. The surface of the gripper limiting plate 3 is provided with a limiting groove 14 for inserting a screw plug. Three limiting grippers 15 are arranged at equal intervals around the outer side of the limiting groove 14. The screw plug in the limiting groove 14 can be clamped and fixed by the limiting grippers 15 approaching each other. It should be noted that the gripper limiting plate 3 and the limiting grippers 15 are existing technologies and will not be described in detail here.

[0024] In use, first insert the plug to be processed into the limiting groove 14, adjust the position of the limiting jaw 15 to limit and fix the root of the plug, and improve the stability during the processing. After processing one side, start the motor 8. The power output end of the motor 8 drives the worm 10 to rotate. The worm 10 meshes with the worm wheel 11, driving the worm wheel 11 to rotate, which in turn drives the rotating shaft 12 to rotate, so that the second gear 7 rotates in the groove 6. The second gear 7 meshes with the first gear 4, driving the first gear 4 to rotate, so that the rotating roller 13 drives the jaw limiting disk 3 to rotate, which can rotate the plug to the side to be processed.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
