Description

Technical Field

[0002] Chamfering refers to the process of cutting the edges and corners of a workpiece into a certain slope. Chamfering is to remove burrs on parts caused by machining and to facilitate part assembly. Generally, chamfers are made on the ends of parts. During the production and manufacturing process of metal workpieces, there are often a lot of burrs on the edges of the corners or holes of the workpieces, and the edges of the workpieces need to be chamfered.

[0003] For metal products such as pipes, the upper and lower ends of the pipes need to be chamfered. The existing chamfering machines for pipes can only chamfer one end of the pipe at a time.

[0020] 4.

[0042] like Figures 1 to 5 As shown, a double-station pipe chamfering equipment includes a body 1, wherein the body 1 is provided with two chamfering stations, each of the chamfering stations is provided with a fixing mechanism for fixing the pipe and a chamfering unit 3, wherein the fixing mechanism includes a fixing portion 4 for the pipe to be sleeved, wherein the fixing portion 4 has a first end portion 41 and a second end portion 42 respectively corresponding to the two ends of the pipe, and the chamfering unit 3 includes a first chamfering portion 311 and a second chamfering portion 321, wherein the first chamfering portion 311 and the second chamfering portion 321 can chamfer the two ends of the pipe located at the first end portion 41 and the second end portion 42 respectively.

[0043] The double-station pipe chamfering equipment of the present application includes a body 1, in which two chamfering stations are arranged, each of which is provided with a fixing mechanism and a chamfering unit 3, which can meet the simultaneous chamfering operation of two pipes and increase the chamfering efficiency; in addition, the chamfering unit 3 includes a first chamfering portion 311 and a second chamfering portion 321, which can simultaneously chamfer the upper and lower ends of the pipe mounted on the fixing portion 4, and there is no need to chamfer one end of the pipe before chamfering the other end, which greatly improves the chamfering efficiency of the chamfering equipment. When the chamfering equipment is applied to an assembly line, it can greatly improve the production and processing efficiency of the assembly line, which helps to improve the assembly line processing efficiency of pipes.

[0044] The first end 41 and the second end 42 of the present application do not refer to two specific points, but are adaptively adjusted according to the length of the pipe, referring to the two points at the two ends of the pipe corresponding to the fixing portion 4. When the pipe is longer, the distance between the first end 41 and the second end 42 is longer, and when the pipe is shorter, the distance between the first end 41 and the second end 42 is shorter.

[0045] Specifically, Figure 1 As shown, the chamfering station includes a first chamfering station 8 and a second chamfering station 9 .

[0046] As a preferred embodiment of the present application, the fixing mechanism further includes a rotating part connected to the fixing part 4, and the rotating part can drive the fixing part 4 to rotate, so that the pipe sleeved on the fixing part 4 rotates synchronously. When chamfering, the first chamfering part 311 and the second chamfering part 321 do not need to move, and the relative movement between the pipe and the first chamfering part 311 and the second chamfering part 321 can be achieved by the rotation of the fixing part 4 driven by the rotating part, so that the first chamfering part 311 and the second chamfering part 321 can chamfer the two ends of the pipe. On the one hand, since the pipe does not need to occupy additional space during the rotation process, the working space required for chamfering is reduced, which is conducive to the miniaturization of the chamfering equipment and optimizes the structural design of the chamfering equipment; on the other hand, chamfering is achieved by rotating the pipe, so that the first chamfering part 311 and the second chamfering part 321 are synchronized for the chamfering of the two ends of the pipe, which minimizes the working time required for pipe chamfering and further improves the chamfering efficiency of the chamfering equipment.

[0047] Specifically, after the pipe is sleeved on the fixing part 4, the relative positions of the two ends of the pipe and the first chamfered part 311 and the second chamfered part 321 are adjusted so that the two ends of the pipe are respectively abutted against the first chamfered part 311 and the second chamfered part 321, and the degree of abutment is determined by the chamfering parameters. Then, the rotating part drives the fixing part 4 to rotate, and the pipe fixed on the fixing part 4 rotates synchronously therewith. The two ends of the pipe are cut by the first chamfered part 311 and the second chamfered part 321 during the rotation process, thereby realizing the chamfering of the pipe.

[0048] As a preferred embodiment of this implementation, Figure 3 As shown, the rotating part includes a rotating motor 5 and a main shaft device connected to the rotating motor 5, the main shaft device includes a rotating shaft 6, and the fixing part 4 is installed on the rotating shaft 6 and can expand outward to be tightly pressed against the inner wall of the pipe.

[0049] By arranging the main shaft device and the rotating shaft 6, on the one hand, the rotating shaft 6 provides an installation position for the fixing part 4, so that the fixing part 4 can be stably placed on the rotating shaft 6, and on the other hand, the fixing part 4 can expand outward and press against the inner wall of the pipe, and lock the pipe on the fixing part 4 by friction, thereby enhancing the tightness of the connection between the pipe and the fixing part 4, and reducing the probability of the pipe being misaligned with the fixing part 4 during rotation, thereby ensuring the stability of the relative position between the pipe and the first chamfered part 311 and the second chamfered part 321, which helps to improve the chamfering accuracy; in addition, the fixing part 4 expands from the inside to press against the pipe, so that the fixing part 4 does not need to occupy the space outside the outer wall of the pipe, reducing the interference of the fixing part 4 on the first chamfered part 311 and the second chamfered part 321, and making the spatial layout of the chamfering equipment more reasonable.

[0050] As a preferred example under this embodiment, Figure 3 As shown, the fixing part 4 includes a plurality of fixing plates 44, each of which has an arc-shaped abutting surface 43 away from the rotating shaft 6, and each of the fixing plates 44 is connected to the rotating shaft 6 via a telescopic mechanism. Since the inner wall of the pipe is arc-shaped, the arc-shaped abutting surface 43 can be provided to increase the fit between the fixing plate 44 and the pipe, thereby enhancing the friction between the fixing plate 44 and the pipe, and providing a guarantee for the stable loading of the pipe on the fixing part 4.

[0051] As a preferred embodiment of the present application, Figure 3 As shown, the fixing portion 4 extends in the vertical direction, the first end portion 41 is located above the second end portion 42, and the chamfering unit 3 includes a first chamfering mechanism 31 and a second chamfering mechanism 32 which are arranged in sequence from top to bottom, the first chamfering portion 311 is provided in the first chamfering mechanism 31, and the second chamfering portion 321 is provided in the second chamfering mechanism 32.

[0052] When the first chamfered portion 311 and the second chamfered portion 321 are chamfering the pipe, it is bound to cause vibration of the pipe. The fixing portion 4 is set to extend in the vertical direction, and the pipe sleeved on the fixing portion 4 also extends in the vertical direction. When the pipe is affected by vibration, the pipe is not easy to fall out of the fixing portion 4 under the action of its own gravity, which helps to improve the fixing effect of the fixing portion 4 on the pipe.

[0053] As a preferred embodiment of this implementation, Figure 1 , Figure 3 As shown, it also includes a pipe positioning mechanism 7, and the pipe positioning mechanism 7 has a positioning portion 71, and the positioning portion 71 can abut against the second end portion 42 to limit the relative movement of the pipe and the fixing portion 4. After the pipe is sleeved on the fixing portion 4, it will slide downward under the action of its own weight. The positioning portion 71 can abut against the second end portion 42 to limit the sliding of the pipe on the fixing portion 4, so that the pipe is stably placed in a preset position, so that the pipe can maintain the relative position with the first chamfered portion 311 and the second chamfered portion 321. Specifically, the positioning portion 71 can abut against the fixing portion 4, and when the pipe is sleeved on the fixing portion 4, it falls to the height where the second end portion 42 abuts against the positioning portion 71 under the action of its own weight and stops, so that the positioning portion 71 locks the relative position of the pipe and the fixing portion 4.

[0054] As a preferred example under this embodiment, Figure 3 As shown, the positioning mechanism further includes a push cylinder 72 connected to the positioning portion 71, and the push cylinder 72 can push the positioning portion 71 to move toward or away from the fixing portion 4. Before the pipe is sleeved on the fixing portion 4, the positioning portion 71 is first pushed to abut against the fixing portion 4 by the push cylinder 72, and then the pipe is sleeved on the fixing portion 4. The pipe continues to fall under the action of its own weight until the second end portion 42 abuts against the positioning portion 71, thereby stopping the falling process, and then the fixing portion 4 locks the position of the pipe, and the positioning portion 71 can be driven away from the fixing portion 4 by the push cylinder 72, and the subsequent chamfering work can be carried out.

[0055] As another preferred embodiment of this embodiment, Figure 1 As shown, it also includes a mounting plate 2, and the first chamfering mechanism 31 and the second chamfering mechanism 32 are both mounted on the mounting plate 2. By providing the mounting plate 2, mounting positions are provided for the first chamfering mechanism 31 and the second chamfering mechanism 32 at the same time, eliminating the operation of separately providing mounting positions for the first chamfering mechanism 31 and the second chamfering mechanism 32, which helps to optimize the structural design of the chamfering device.

[0056] As a preferred embodiment of the present application, Figure 1 , Figure 2As shown, the machine body 1 includes a base 11 and a shell 12, the chamfering station is arranged on the top of the base 11, the base 11 and the shell 12 cooperate to form a working chamber, the fixing mechanism and the chamfering unit 3 are located in the working chamber, and the working chamber has an observation window. By providing the base 11 and the shell 12, and cooperating the base 11 and the shell 12 to form a working chamber, a working space is provided for the chamfering of the pipe, and the base 11 and the shell 12 can play a certain shielding role for the debris generated during chamfering, thereby reducing the probability of the debris generated during chamfering being ejected outward.

[0057] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0058] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0059] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
