Description

Technical Field

[0001] This utility model relates to the field of automotive pipe bending processing technology, and in particular to a pipe bending, cutting and chamfering device. Background Technology

[0002] The lathe machining process for bending automotive pipes generally includes cutting and chamfering. Cutting and chamfering require two clamping operations, which is inefficient and can easily lead to large machining tolerances due to positional changes caused by multiple clamping operations. Utility Model Content

[0003] To address the low efficiency caused by multiple clamping operations in existing pipe bending and chamfering processes, this invention provides a pipe bending and chamfering device that integrates pipe bending and chamfering procedures.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A pipe bending and chamfering device, comprising:

[0006] A mobile platform that moves along the X and Y directions;

[0007] A clamp assembly, which is mounted on a mobile platform, is used to fix a bent pipe;

[0008] A rotating shaft is arranged axially along the X direction. A cutting tool and a chamfering tool are fixed on the rotating shaft. The chamfering tool is located at the end of the rotating shaft. The cutting direction of the cutting tool is arranged along the Y direction.

[0009] Furthermore, the clamping assembly includes a base plate fixed to the moving platform, the base plate having a groove adapted to the shape of the bent pipe, and the clamping assembly also includes a pressure plate connected to a drive mechanism for lifting and lowering the pressure plate. The groove limits the bent pipe in the horizontal direction, and the pressure plate limits the bent pipe in the vertical direction, thereby ensuring that the bent pipe will not shift during processing.

[0010] Furthermore, the drive mechanism includes a cylinder fixed to the base plate, and the pressure plate is driven to rise and fall by the cylinder. Using a cylinder as the drive mechanism is low-cost and easy to manufacture and implement.

[0011] Furthermore, the piston rod of the cylinder is fixedly connected to an upper connecting rod, and the upper connecting rod is fixedly connected to the pressure plate via an intermediate connecting rod. The bottom of the cylinder is fixed to the base plate, and the connection between the pressure plate and the cylinder is achieved through the upper connecting rod and the intermediate connecting rod. This eliminates the need for an additional cylinder mounting bracket, resulting in a more integrated overall structure, smaller footprint, and easier processing.

[0012] Furthermore, it also includes an air blowing device, which comprises an air blowing pipe with its outlet aligned with the inner cavity of the bend. The air blowing device can blow out debris from the inner cavity of the bend, preventing residual debris from affecting subsequent processing or installation.

[0013] Furthermore, a limiting plate is detachably fixed to the base plate, and the limiting plate presses against the end of the air blowing pipe. The limiting plate limits the position of the air blowing pipe, which only needs to be aligned with the inner cavity of the bend.

[0014] Beneficial effects:

[0015] (1) The bending pipe cutting and chamfering device of this utility model realizes the cutting and chamfering of the end of the bending pipe. It can complete the two processes of cutting and chamfering in one clamping, which is highly efficient and has high processing accuracy.

[0016] (2) The clamping assembly of this utility model uses a base plate and a cylinder for clamping, which is simple in structure and easy to implement;

[0017] (3) The bending and chamfering device of this utility model also includes an air blowing device, which can blow out the debris generated during the cutting and chamfering process from the cavity of the bending pipe to ensure the processing effect;

[0018] (4) The base plate can be detached and fixed on the mobile platform. The base plate can be replaced according to the shape and size of the bent pipe. The limiting plate can be detached and fixed on the base plate. The position of the air blowing pipe can be adjusted, thereby improving the applicability of the bent pipe cutting and chamfering device of this utility model. Attached Figure Description

[0027] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0028] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0029] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model.

Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0031] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0032] like Figures 1-3 A pipe bending and chamfering device includes a moving platform, a clamping assembly 2, and a rotating shaft 3. The moving platform moves along the X and Y directions; the clamping assembly 2 is mounted on the moving platform and is used to fix the bent pipe 1; the rotating shaft 3 is axially arranged along the X direction, and a cutting tool 4 and a chamfering tool 5 are fixed on the rotating shaft 3. The chamfering tool 5 is located at the end of the rotating shaft 3, and the cutting direction of the cutting tool 4 is arranged along the Y direction. In this invention, the chamfering tool 5 performs internal chamfering on the bent pipe 1. The rotating shaft 3 is a rotating spindle of a machine tool or is fixedly connected to the rotating spindle of a machine tool. In this invention, the rotating shaft 3 is horizontally arranged, and the moving platform drives the bent pipe 1 to the position of the cutting tool 3 or the chamfering tool 5 on the rotating shaft 3 for cutting and chamfering.

[0033] The clamp assembly 2 includes a base plate 21 fixed on the moving platform. Preferably, the base plate 21 is fixed on the moving platform and has a groove 211 that matches the shape of the bent pipe 1. The clamp assembly 2 also includes a pressure plate 22, which is connected to a drive mechanism that drives its lifting and lowering.

[0034] The driving mechanism can be a motor, etc. Preferably, the driving mechanism of this utility model includes a cylinder 23 fixed on the base plate 21, and the pressure plate 22 is driven to rise and fall by the cylinder 23. The piston rod of the cylinder 23 is fixedly connected to an upper connecting rod 24, and the upper connecting rod 24 is fixedly connected to the pressure plate 22 by an intermediate connecting rod 25. The cylinder 23 is fixed next to the groove 211. When the piston rod retracts, the pressure plate 22 descends to press the bent tube 1. When the piston rod extends, the pressure plate 22 rises, at which point the processed bent tube 1 can be taken out. The bent tube 1 to be processed is placed into the groove 211, and then the pressure plate 22 descends to press the bent tube 1. The shape of the groove 211 is adapted to the bent tube, and preferably, the groove 211 corresponds to the bent part of the bent tube 1. The bent tube 1 placed in the groove 211 is limited in the horizontal direction, and then the pressure plate 22 limits the bent tube 1 in the vertical direction, thereby realizing the overall limitation of the bent tube 1.

[0035] The pipe bending and chamfering device also includes an air blowing device, which includes an air blowing pipe 6. The outlet of the air blowing pipe 6 is aligned with the inner cavity of the pipe bending 1. The air blowing pipe 6 can be glued to the base plate 21. In this invention, a limiting plate 7 is detachably fixed on the base plate 21, and the limiting plate 7 presses against the end of the air blowing pipe 6. The limiting plate 7 only applies a certain pressure to the air blowing pipe 6 to prevent it from shifting, and will not flatten it.

[0036] Work process:

[0037] First, the bent pipe 1 is placed on the base plate 21, with the bent portion of the pipe 1 embedded in the groove 211 on the base plate 21. Then, the piston rod of the cylinder 23 retracts, and the pressure plate 22 presses down on the bent pipe 1. Next, the moving platform drives the base plate 21 to move along the X and Y directions, aligning the position of the bent pipe 1 to be cut with the cutting tool 4, ready for cutting. Figure 4 The moving platform moves along the Y direction until the end of the bend 1 is cut. After the cutting is completed, the moving platform moves along the X and Y directions so that the chamfering tool 5 is aligned with the opening at the end of the bend 1. Then the moving platform moves along the X direction to complete the inner chamfer of the bend 1.

[0038] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
