Detailed Implementation

[0019] 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.

[0020] like Figure 1An auxiliary cutting fixture for brake and main air hose connectors, the main components of which include a counterweight base 1, a hose fixing block 2, a rotating head 3, a bolt 4, a support handle 5, a locking block 6, a fixing clamp 7, a positioning rod 8, a fine cutting support rod 9, a positioning nut 10, a coarse cutting support rod 12, and a maximum limit fixing pin 11.

[0021] In this embodiment, the counterweight base 1 is generally H-shaped, with the rotating head 3 installed at one end and the positioning rod 8 installed at the other end. The hose fixing block 2 is installed on the counterweight base 1 between the rotating head 3 and the positioning rod 8. One end of the support handle 5 is rotatably connected to the rotating head 3, and a locking block 6 is slidably installed on the support handle 5. A fixing clamp 7 for fixing the cutting device is connected to one side of the locking block 6. The positioning rod 8 is provided with coarse cutting support rods 12 and fine cutting support rods 9 of different heights. The two support rods are used to limit the tail of the support handle 5.

[0022] In this embodiment, the counterweight base 1 serves as a counterweight carrier, with slots cut into its body for fixing the mounting of the locking block 2, rotating head 3, and positioning rod 8, while also providing balance. The rotating head 3 and the counterweight base 1 are connected by a slider and a groove for rotation and sliding. The slider (located at the bottom of the rotating head, not shown in the figure) is slidably positioned within the groove, and the slider and rotating head are rotatably connected. The rotating head 3 can drive the support handle 5 to move laterally along the groove and rotate, allowing the cutting machine to cut different positions of the iron sleeve without damaging the connector body and joint.

[0023] In this embodiment, the locking block 6 is slidably mounted on the support handle 5, and the two are locked together by a locking bolt. The sliding of the locking block 6 can adjust the cutting depth accuracy. The fixing clamp 7 and the locking block 6 are connected by four fastening long bolts (not shown in the figure), and the gap between the fixing clamp 7 and the locking block 6 can be adjusted by screwing in or out the fastening long bolts to accommodate angle grinders of different models and sizes.

[0024] In this embodiment, the front end of the hose fixing block 2 is provided with a strip-shaped groove for fixing the upper end of the connector, and the rear end is provided with an arc-shaped groove for positioning the hose body. The bottom of the hose fixing block 2 is provided with a strip-shaped protrusion (not shown in the figure), which cooperates with the strip-shaped sliding groove formed on the counterweight base.

[0025] In this embodiment, the bottom of the positioning rod 8 is slidably connected to the counterweight base 1 via a sliding groove, and the upper end is provided with a maximum limit fixing pin 11. The coarse cutting support rod 12 and the fine cutting support rod 9 are rotatably mounted on the positioning rod 8, and positioning nuts 10 are provided at the upper and lower ends of both support rods.

[0026] In this embodiment, the cutting machine used is an existing angle grinder with a cutting disc. For example, a large cutting machine AG5152 is used, with a grinding wheel outer diameter of 5 inches (12.7 cm); a small cutting machine DR-75 is used, with a grinding wheel outer diameter of 2.36 inches (6 cm) or 1.57 inches (4 cm).

[0027] The operation process of this device is as follows: First, fix the large cutting machine in the fixed clamping block 7, and limit it by adjusting the coarse cutting support rod 12. Rotate and move the support handle 5 downward to make the large cutting machine cut a V-shaped opening at the iron sleeve. This allows for batch operation. Then, fix the small cutting machine in the fixed clamping block 7, and limit it by adjusting the fine cutting support rod 9. Rotate and move the support handle 5 downward to cut the root of the iron sleeve at the V-shaped opening corner. Finally, use the expander pliers to remove the iron sleeve, take out the connector body and connector, and complete the work.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that the above embodiments do not limit the scope of protection of this utility model in any way, and all technical solutions obtained by equivalent substitution or other means fall within the scope of protection of this utility model. Parts not covered by this utility model are the same as or can be implemented using existing technology.
