Description

Technical Field

[0001] This utility model relates to the technical field of grooving processing of brass pipe fittings, and in particular to a grooving assembly. Background Technology

[0002] Patent CN207447356U discloses a pipe grooving device, including a frame and a side plate on the frame. A straight groove is provided on the frame. A first linear guide rail is symmetrically distributed on both sides of the straight groove. A motor bracket and a vertical plate are installed on the first linear guide rail. A motor is located at the upper end of the motor bracket. A clamp is connected to the motor. A second linear guide rail is provided on the side plate. A hydraulic cylinder bracket is installed on the second linear guide rail. The hydraulic cylinder bracket is connected to a lead screw motor. A hydraulic cylinder is located at the top of the hydraulic cylinder bracket. The hydraulic cylinder is connected to the grooving plate.

[0003] In the existing pipe grooving device, the device dimensions are first adjusted according to the drawings. Specifically, rotating the handle 9 drives the bolt 8 to move within the nut 7, thereby adjusting the movement of the motor bracket 5 connected to the nut 7. The movement of the motor bracket 5 drives the displacement of the motor 10 connected to it. Since the upright plate 6 is set on the first linear guide rail 4, its position can also be adjusted. The position adjustment of the hydraulic cylinder 16 is achieved by controlling the lead screw motor 15 through the control system 19. After the above positions are determined, the pipe is inserted into the clamp 11 and placed between the two rollers 12. The control system 19 starts the motor 10 to drive the pipe to rotate on the two rollers 12. The hydraulic cylinder 16 starts to drive the grooving plate 17 connected to it to press down on the pipe. The grooving cutter 18 set on the grooving plate 17 will cut a groove on the rotating pipe, completing the grooving process of the pipe.

[0004] The existing technical solutions mentioned above have the following drawbacks: existing similar products cannot perform grooving from the inside of the pipe fittings, and existing equipment suffers significant wear and tear when using grooving tools to cut a groove from the outside of the pipe fittings. Utility Model Content

[0005] The purpose of this invention is to provide a swirl groove assembly.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A grooving assembly includes a drive assembly, a power head assembly, a hydraulic assembly, and a grooving head assembly. The drive assembly internally includes a bottom mounting plate. A guide rail fixing bracket is fixedly connected to the upper end of the bottom mounting plate. A first guide rail body is fixedly connected to the upper end of the guide rail fixing bracket. A motor mounting bracket is fixedly connected to the inner side of the guide rail fixing bracket. A servo drive motor is fixedly connected to one end of the motor mounting bracket. A lead screw body is fixedly connected to the output end of the servo drive motor. A lead screw fixing plate adapted to the lead screw body is movably connected to the outer side of the lead screw body. A hydraulic assembly and a grooving head assembly are fixedly mounted on the upper end of the lead screw fixing plate. A power head assembly is provided above the hydraulic assembly and the grooving head assembly. A first slider body is fixedly connected to the lower end of the lead screw fixing plate. The first slider body is slidably connected to the first guide rail body.

[0008] By adopting the above technical solution, the pipe fittings can be effectively grooved from the inside, reducing material loss. It also has the advantages of stable workpiece processing quality and accurate precision requirements, truly improving work efficiency and reducing labor costs, thus maximizing the economic benefits for enterprise development.

[0009] Furthermore, the hydraulic assembly includes an oil pipe transition piece, one end of which is fixedly connected to a transition mounting flange. A housing is fixedly connected to the side of the transition mounting flange away from the oil pipe transition piece. A slider mounting plate is fixedly connected to the housing away from the transition mounting flange. A second guide rail body is fixedly connected to the outer side of the slider mounting plate. A second slider body is slidably connected to the outer side of the second guide rail body. A swirl head mounting flange of the swirl head assembly is fixedly connected to the side of the second slider body away from the second guide rail body. A piston is provided inside the swirl head mounting flange.

[0010] By adopting the above technical solution, when hydraulic oil enters the housing through the oil pipe transition piece, the oil pressure will lift the piston and drive the grooving head assembly mounting flange to shift through the second guide rail body and the slider. When the mounting flange shifts, the mold spring on the spring adjusting rod will also stretch or retract with the piston change. This allows the grooving head assembly to rotate eccentrically during the workpiece grooving process, completing the internal grooving process of the workpiece.

[0011] Furthermore, a spring adjusting rod is provided inside the mounting flange of the swivel head, and the spring adjusting rod is a structure in which a spring drives a movable rod to move within the groove.

[0012] By adopting the above technical solution, the mold spring on the spring adjusting rod of the structure in which the spring drives the movable rod to move in the groove will also be stretched or retracted with the change of the piston; thus, the grooving head assembly can rotate eccentrically during the workpiece grooving process to complete the internal grooving process of the workpiece.

[0013] Furthermore, the grooving head assembly includes a bearing sleeve inside, a bearing body is fixedly installed inside the bearing sleeve, a grooving head fixing shaft is fixedly connected inside the bearing body, the grooving head fixing shaft is rotatably connected to the bearing sleeve through the bearing body, a grooving head body is fixedly connected inside the grooving head fixing shaft, and a pressure cap is fixedly connected to the side of the grooving head body away from the grooving head fixing shaft.

[0014] By adopting the above technical solution, when the power head motor drives the hydraulic component and the grooving head component to rotate together, the hydraulic component will offset and rotate according to the required grooving size, while driving the grooving head component to rotate together, thus completing the grooving process.

[0015] Furthermore, a locking nut for fixing is provided at one end of the bearing body, and the bearing body is fixedly connected to the bearing sleeve by the locking nut.

[0016] By adopting the above technical solution, the pipe fittings can be effectively grooved from the inside, reducing material loss and providing advantages such as stable workpiece processing quality and accurate precision requirements.

[0017] In summary, the beneficial technical effects of this utility model are as follows:

[0018] 1. It adopts drive components, power head components, hydraulic components and grooving head components, which can effectively groove the pipe fittings from the inside, reduce material loss, and has the advantages of stable workpiece processing quality and accurate precision requirements. It truly improves work efficiency and reduces labor costs, maximizes the economy for enterprise development, and achieves the effect of low loss and high efficiency.

[0019] 2. When the power head motor drives the hydraulic components and the grooving head components to rotate together, the hydraulic components will offset and rotate according to the required grooving size, while driving the grooving head components to rotate together, thus completing the grooving process and achieving the effect of easy adjustment and processing.

[0020] 3. This design is applicable to the internal machining of pipe fittings by grooving. It can improve the machining efficiency and accuracy of pipe fittings by rolling grooves, and effectively solve the problem of eccentricity that may occur when machining pipe fittings and machining mechanisms, thus greatly improving the quality of finished products and increasing production efficiency.
