Description

Technical Field

[0001] This utility model relates to the field of chamfering equipment, and in particular to a double-headed flat chamfering equipment. Background Technology

[0002] A chamfering machine is a machine used to chamfer the edges and corners of a workpiece. It is mainly used in metal processing, wood processing, plastic processing and other fields. The working principle of a chamfering machine is to use a cutting edge to cut the edge of the workpiece to form a chamfer.

[0003] In the existing technology, the pipe fittings need to be clamped by a pipe clamping mechanism, and then the two ends of the pipe fittings need to be chamfered by a worker using a hand-held cutting device. The clamping of the pipe fittings is done manually, and the chamfering also requires manual operation. The operation is time-consuming and labor-intensive, and the chamfering efficiency is low.

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0030] This application discloses a double-headed flat chamfering device.

[0031] Reference Figure 1-3 The double-head flat chamfering equipment includes a workbench 1, on which a feeding mechanism 2, a transfer mechanism 3, and a chamfering mechanism 4 are installed.

[0032] The feeding mechanism 2 includes a storage frame 21, which is inclined. The bottom end of the storage frame 21 is fixed to the worktable 1 via a lifting frame 211. Multiple workpieces 5 are placed along the length of the storage frame 21, with adjacent workpieces 5 abutting against each other. A transition plate 22 is provided at the lowest end of the storage frame 21. The transition plate 22 is horizontally positioned, and its width is greater than the diameter of the workpiece 5. One workpiece 5 at the lowest end falls onto the transition plate 22 under gravity. A weight-reducing groove is provided on the bottom plate of the storage frame 21, and the two end faces of the workpiece 5 are in contact with the two side plates of the storage frame 21.

[0033] A partition plate 23 is provided between the transition plate 22 and the lowest end of the storage frame 21. The partition plate 23 is raised and lowered by a lifting cylinder 24. The lifting cylinder 24 is fixed to the storage frame 21 by a mounting frame 25. The partition plate 23 can be lowered to separate the workpiece 5 on the transition plate 22 from the adjacent workpiece 5.

[0034] The transfer mechanism 3 is used to transfer the workpiece 5 on the transition plate 22 to the chamfering mechanism 4.

[0035] The chamfering mechanism 4 simultaneously chamfers both ends of the workpiece 5. The chamfering mechanism 4 includes two coaxially arranged chamfering cutters 41. The two chamfering cutters 41 are coaxial with the workpiece 5, and the chamfering faces of the chamfering cutters 41 are aligned with the peripheral side of the end of the workpiece 5. The ends of the two chamfering cutters 41 that are far apart from each other are rotated through a transmission assembly.

[0036] The transmission assembly includes a rotary motor 43, a power head 44, and a coupling 42. The housing of the rotary motor 43 is fixedly mounted on the housing of the power head 44. The output end of the rotary motor 43 is coaxially connected to the input end of the power head 44. The output end of the power head 44 is coaxially connected to the chamfering cutter head 41 through the coupling 42.

[0037] The power head 44 slides through the lead screw module 45. The power head 44 is fixed to the output end of the lead screw module 45 through the connecting cover 46. The housing of the power head 44 is fixedly connected to the top surface of the connecting cover 46. The bottom surface of the connecting cover 46 is fixedly connected to the output end of the lead screw module 45. The two power heads 44 move towards each other or away from each other through the corresponding lead screw modules 45.

[0038] The transfer mechanism 3 includes a first conveying component 31 and a second conveying component 32. The first conveying component 31 moves the workpiece 5 along the axial direction of the workpiece 5, and the second conveying component 32 moves the workpiece 5 along the radial direction of the workpiece 5.

[0039] The transition plate 22 extends along the length direction to the chamfering mechanism 4.

[0040] The first conveying assembly 31 includes a push cylinder 311 and a push plate 312. The push cylinder 311 is fixed to the worktable 1 by a bracket 313. The push cylinder 311 is located at the end of the transition plate 22 away from the second conveying assembly 32 in the length direction. The push plate 312 includes a first section 3121 and a second section 3122 that are perpendicular to each other. The first section 3121 of the push plate 312 is fixedly connected to the piston rod of the push cylinder 311. The end of the second section 3122 away from the first section 3121 is in contact with the end face of the workpiece 5.

[0041] The transition plate 22 is provided with a positioning plate 221 at the end away from the push cylinder 311. When the workpiece 5 abuts against the positioning plate 221, the second conveying assembly 32 slides the workpiece 5 radially between the two chamfering cutter heads 41.

[0042] After the workpiece 5 falls from the storage box 21 onto the transition plate 22, the piston rod of the push cylinder 311 extends, and the push plate 312 pushes the workpiece 5 toward the direction of the second conveying assembly 32.

[0043] The second conveying assembly 32 includes a first pressing block 321, a second pressing block 322, a first pushing cylinder 323, and a second pushing cylinder 324. The first pressing block 321 and the second pressing block 322 are respectively slidably disposed on both sides of the chamfering cutter head 41 in the radial direction. The first pushing cylinder 323 and the second pushing cylinder 324 are both fixed on the worktable 1 by a fixing frame. The piston rod of the first pushing cylinder 323 is fixed to the first pressing block 321, and the piston rod of the second pushing cylinder 324 is fixed to the second pressing block 322. The first pressing block 321 and the storage frame 21 are located on the same side.

[0044] The push cylinder 311 pushes the workpiece 5 from the feeding mechanism 2 to between the first pressing block 321 and the second pressing block 322. After the piston rod of the second push cylinder 324 extends, the second pressing block 322 moves toward the first pressing block 321 and cooperates with the first pressing block 321 to press the workpiece 5 together.

[0045] The piston rod of the first pushing cylinder 323 extends and the piston rod of the second pushing cylinder 324 retracts. The first pressing block 321 and the second pressing block 322 move synchronously, driving the workpiece 5 to be moved between the two chamfering cutter heads 41 and coaxially arranged with the two chamfering cutter heads 41.

[0046] The first abutting block 321 and the second abutting block 322 have an arc-shaped mating groove on their sides that are close to each other, which is used to accommodate the workpiece 5. The inner arc surface of the mating groove fits against the outer peripheral surface of the workpiece 5, so that the first abutting block 321 and the second abutting block 322 fit the workpiece 5 better.

[0047] The implementation principle of a double-head flat chamfering device according to an embodiment of this application is as follows:

[0048] After the worker places several workpieces 5 on the storage box 21, the workpieces 5 slide automatically along the storage box 21 to the transition plate 22 under the action of gravity. The partition plate 23 descends to separate the workpieces 5 on the transition plate 22 from the workpieces 5 on the storage box 21. Then, the transfer mechanism 3 moves the workpieces 5 to the chamfering mechanism 4. Then, the two chamfering cutters 41 move towards each other to align with the periphery of the end of the workpiece 5. The two chamfering cutters 41 rotate at high speed while slowly moving towards each other, and simultaneously chamfer both ends of the workpiece 5, realizing automatic feeding and material feeding. The degree of automation is high, the operation is convenient, and the overall chamfering efficiency of the workpiece 5 is improved.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
