Description

Technical Field

[0001] This utility model relates to the field of internal tube gear machining technology, and more specifically to an auxiliary gripper for internal tube gear machining. Background Technology

[0002] In various machinery manufacturing industries, many products' key components are tubular parts with internal toothed structures, such as certain bushings in automotive transmission systems, hydraulic pipeline connectors in construction machinery, and miniature conduits in precision instruments. The presence of these internal teeth plays a crucial role in achieving precise power transmission, fluid control, and accurate fit between components.

[0003] Currently, the machining of internal teeth in tubes is mainly carried out using CNC lathes, milling machines, or other special-purpose machine tools. However, due to the inherent geometric characteristics of tubular parts—their hollow structure and relatively large length-to-diameter ratio—accurate tooth profile machining inside them presents numerous challenges. In particular, during the machining process, how to stably clamp the tube to ensure machining accuracy and surface quality has become one of the key factors restricting production efficiency and product quality.

[0004] As shown in the prior art published in CN221416402U, although this prior art, by setting up a lifting lighting device, allows the operator to adjust the height of the clamping assembly when needed through the cooperation of the first lead screw and connecting frame, thereby better meeting the work needs in different situations, and the clamping jaws can be illuminated by various lights when needed, thus improving the working capacity of the clamping jaws, this prior art can only limit the end of the pipeline, resulting in insufficient support strength at the end of the pipeline away from the clamping jaws, which will affect the stability of the pipeline during processing. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides an auxiliary gripper for internal gear machining. Through the meshing of the main bevel gear and the driven bevel gear, the adjusting plate on the adjusting rod can be moved outward, and the pressure plate on the adjusting plate can fix the pipeline, thereby ensuring the stability of the pipeline during machining. Furthermore, the support tube can move the pipeline to be machined to a suitable position, thus effectively ensuring the machining stability of the pipeline and preventing the pipeline from skewing and deforming due to pressure imbalance, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an auxiliary gripper for machining internal teeth of pipes, including a base, a support tube on the top of the base, an auxiliary component for fixing the pipe on the outside of the support tube, and the support tube driving the auxiliary component through a linkage component; The auxiliary component includes a fixing plate that is fixedly connected to both sides of the support tube.

An adjusting plate is externally threaded to the end of the adjusting rod near the support tube. A pressure plate is installed on the side of the adjusting plate near the support tube.

[0007] In a preferred embodiment, the linkage includes a movable ring sleeved on the outside of the support tube. The movable ring is movably connected to the support tube via a bearing, and the cross-section of the movable ring is T-shaped. A main bevel gear is sleeved on the outer rear end of the movable ring. Both ends of the main bevel gear are meshed with driven bevel gears on their rear sides. A linkage shaft is installed on the side of the driven bevel gear near the fixed plate. The linkage shaft passes through the fixed plate and is fixed together with the adjusting rod.

[0008] In a preferred embodiment, a driven gear is sleeved on the front end of the movable ring, a master gear is meshed at the top of the driven gear, and a servo motor for driving the master gear is installed at the top of the support tube.

[0009] In a preferred embodiment, both the cross-section of the adjusting plate and the cross-section of the fixing groove are rectangular, and the outer side of the adjusting plate is in contact with the inner wall of the fixing groove.

[0010] In a preferred embodiment, a fixed bracket is installed on the top of the base, and the front and rear ends of the fixed bracket are respectively sleeved on the outside of the front ends of the support tube.

[0011] In a preferred embodiment, the base has multiple mounting holes on its top, which are evenly spaced apart.

[0012] The technical effects and advantages of this utility model are as follows: The meshing of the main bevel gear and the driven bevel gear allows the adjusting plate on the adjusting rod to move outward, and the pressure plate on the adjusting plate to fix the pipeline, thereby ensuring the stability of the pipeline during processing. The support tube can move the pipeline to be processed to a suitable position, thus effectively ensuring the processing stability of the pipeline and preventing the pipeline from becoming skewed or deformed due to pressure imbalance.

[0015] 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.

[0016] Refer to the instruction manual appendix Figure 1-5 This utility model provides an auxiliary gripper for machining internal gears in pipes, including a base 1. A support pipe 2 is provided on the top of the base 1. An auxiliary component for fixing the pipe is provided on the outside of the support pipe 2, and the support pipe 2 drives the auxiliary component through a linkage component. The auxiliary component includes a fixing plate 3 fixedly connected to both sides of the support pipe 2. A fixing groove 4 is opened on the side of the fixing plate 3 near the support pipe 2. An adjusting rod 5 is installed inside the fixing groove 4 and is movably connected to the fixing rod 5 through a bearing. An adjusting plate 6 is externally threaded to the end of the adjusting rod 5 near the support pipe 2. A pressure plate 7 is installed on the side of the adjusting plate 6 near the support pipe 2. Through the meshing of the main bevel gear 9 and the driven bevel gear 10, the adjusting plate 6 on the adjusting rod 5 can be moved outward, and the pressure plate 7 on the adjusting plate 6 can fix the pipe, thereby ensuring the stability of the pipe during machining. The support pipe 2 can move the pipe to be machined to a suitable position, thus effectively ensuring the machining stability of the pipe.

[0017] When using the aforementioned support tube 2 to perform internal gear machining on the pipeline, the operator places the pipeline to be machined inside the support tube 2, and then drives the auxiliary component to operate through the linkage component. The linkage component includes a movable ring 8 sleeved on the outside of the support tube 2. The movable ring 8 is movably connected to the support tube 2 through a bearing, and the cross-section of the movable ring 8 is T-shaped. A main bevel gear 9 is sleeved on the outer rear end of the movable ring 8. Both ends of the main bevel gear 9 are meshed with driven bevel gears 10. A linkage shaft 11 is installed on the side of the driven bevel gear 10 near the fixed plate 3. The linkage shaft 11 passes through the fixed plate 3 and is fixed together with the adjusting rod 5.

[0018] In this way, the operation of the main bevel gear 9 drives the two driven bevel gears 10 to operate. The two driven bevel gears 10 drive the two adjusting rods 5 to operate synchronously through the corresponding linkage shaft 11. The two adjusting rods 5 then drive the corresponding adjusting plate 6 to move outward. The adjusting plate 6, together with the pressure plate 7, contacts the pipeline, thereby achieving the effect of limiting and fixing the pipeline. In addition, the setting of the support pipe 2 can move the pipeline to be processed to a suitable position, thereby effectively ensuring the processing stability of the pipeline and avoiding the situation of the pipeline being skewed and deformed due to pressure imbalance.

[0019] To ensure the stability of the adjusting plate 6 during its displacement, it is necessary to limit its movement. Therefore, both the cross-section of the adjusting plate 6 and the cross-section of the fixing groove 4 are rectangular, with the outer surface of the adjusting plate 6 in contact with the inner wall of the fixing groove 4. This allows the fixing groove 4 to guide and limit the movement of the adjusting plate 6, ensuring its stability as it moves the pressure plate 7 and preventing the adjusting plate 6 from tilting during displacement.

[0020] To improve the operating efficiency of the drive adjustment lever 5, a driven gear 12 is sleeved on the outer side of the front end of the movable ring 8. The top of the driven gear 12 meshes with a main gear 13, and a servo motor 14 for driving the main gear 13 is installed at the top of the support tube 2. In this way, the servo motor 14 can drive the main gear 13 to rotate, and the main gear 13 drives the movable ring 8 to rotate through the meshing driven gear 12. The movable ring 8 can then drive the main bevel gear 9 to rotate, and the main bevel gear 9 can drive the driven bevel gear 10, thereby improving the operating efficiency of the drive adjustment lever 5.

[0021] To ensure the stability of the support tube 2, it needs to be supported and fixed. Therefore, a fixing bracket 15 is installed on the top of the base 1, with its front and rear ends respectively fitted onto the outer ends of the front end of the support tube 2. This fixes the support tube 2 with the bracket 15, ensuring its support strength and stability, and preventing it from tilting or swaying.

[0022] Furthermore, since the base 1 has multiple mounting holes 16 at its top, and these mounting holes 16 are evenly spaced, the operator needs to fix the base 1 when operating the support tube 2 and other equipment. Therefore, the base 1 can be fixed to a suitable position by using fastening equipment connected to the mounting holes 16.

[0023] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
