Description

Technical Field

[0002] At present, a Chinese patent with authorization announcement number CN216801859U discloses a planer, which includes a planer machine, a fixed rod arranged on one side of the planer machine, two fixed plates hinged on the upper end of the fixed rod, each fixed plate is slidably connected with an extension plate, and a locking plate is arranged on the lower side of the fixed plate corresponding to the fixed rod.

[0003] This planer has the effect of improving the fixation of the workpiece during planing and milling.

[0004] However, when the keyway is to be planed on the worm, the worm is fixed with a three-jaw chuck, and then the keyway is planed out of the worm with a planer. However, due to process requirements, a back-cut groove must be pre-opened on the worm, which requires a lathe to be used first. After the back-cut groove is machined on the worm, the worm is placed on a planer for processing. The operation is cumbersome and has a certain impact on the processing accuracy of the worm.

[0033] The specific implementation modes of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.

[0034] A combined planer for worm hole planing and key slot planing comprises a workbench 1. The workbench 1 is slidably connected with a positioning table 2 along its longitudinal direction.

[0035] Two parallel first guide rails 11 are fixedly connected to the workbench 1, and the positioning platform 2 is slidably connected to the first guide rails 11. A first motor 12 is fixedly connected to the end of the workbench 1, and a first screw 13 is fixedly connected to the first motor 12, and the first screw 13 is threadedly connected to the positioning platform 2. The first guide rails 11 and the first screw 13 are both arranged along the longitudinal direction of the workbench 1.

[0036] When the first motor 12 is started, the positioning table 2 can be moved along the longitudinal direction of the workbench 1 .

[0037] A three-jaw chuck 21 is fixedly connected to one end of the positioning platform 2. The top 5 is slidably connected to the positioning platform 2 and corresponds to the three-jaw chuck 21. Two parallel second guide rails 22 are fixedly connected to the positioning platform 2. The positioning frame 23 is slidably connected to the second guide rail 22. The top 5 is fixed to the positioning frame 23 and corresponds to the three-jaw chuck 21.

[0038] A second motor 24 is fixedly connected to the positioning platform 2, and a second screw 25 is fixedly connected to the second motor 24, and the second screw 25 is threadedly connected to the positioning frame 23. The second screw 25 and the second guide rail 22 are both arranged along the longitudinal direction of the workbench 1.

[0039] One end of the worm 10 is fixed by the three-jaw chuck 21, and the second motor 24 is started. The second screw 25 rotates, and the positioning frame 23 drives the top 5 to move synchronously, so that the top 5 is pressed against the end of the worm 10 away from the three-jaw chuck 21 to achieve complete positioning of the worm 10.

[0040] A mounting hole 31 with a circular cross section is provided on the side wall of the positioning frame 23, and a limiting tube 32 coaxially arranged with the mounting hole 31 is fixedly connected to the side wall of the positioning frame 23. A plurality of elastic clamping plates 33 made of copper are fixedly connected to the end of the limiting tube 32, and there is a gap between two adjacent elastic clamping plates 33. The plurality of elastic clamping plates 33 are evenly distributed along the axis of the limiting tube 32. A locking sleeve 34 is threadedly connected to the outer wall of the limiting tube 32.

[0041] The top 5 is passed through the limiting tube 32 and then into the mounting hole 31 , the position of the top 5 is adjusted, and then the locking sleeve 34 is rotated toward the positioning frame 23 , and the elastic clamping plate 33 is pressed against the top 5 through the conductive structure 4 .

[0042] The conductive structure 4 includes a conductive slope 41, a conductive ring 42, and a guide slope 43. The conductive slope 41 is formed on the outer wall of the elastic clamp 33. The conductive ring 42 is fixed on the inner wall of the locking sleeve 34, and the conductive ring 42 and the locking sleeve 34 are coaxially arranged. The guide slope 43 is formed on the conductive ring 42 and contacts the conductive slope 41.

[0043] Accordingly, when the locking sleeve 34 is rotated toward the positioning frame 23, the conductive inclined surface 41 contacts the guiding inclined surface 43, so that the elastic clamping plate 33 is bent to be in tight contact with the outer wall of the top 5, and the friction force generated achieves the positioning of the top 5. In addition, since multiple elastic clamping plates 33 are bent at the same time, the top 5 is subjected to a more uniform force, so that the top 5 is not easily displaced during the locking process.

[0044] A limiting ring 51 is fixedly connected to the outer wall of the top 5 , and the limiting ring 51 is coaxially arranged with the top 5 . The limiting ring 51 is used to abut against the outer wall of the locking sleeve 34 .

[0045] The workbench 1 is connected to the processing table 6 in a slidable manner in the transverse direction of the workbench 1. Two third guide rails 61 arranged in parallel are fixedly connected to the workbench 1, and the processing table 6 is slidably connected to the third guide rails 61. A third motor 62 is fixedly connected to the workbench 1, and a third screw 63 is fixedly connected to the third motor 62, and the third screw 63 is threadedly connected to the processing table 6. The third screw 63 and the third guide rail 61 are both arranged in the transverse direction of the workbench 1.

[0046] When the third motor 62 is turned on, the third screw 63 can be rotated, and the processing table 6 can move along the length direction of the third guide rail 61 , that is, the processing table 6 can move in the transverse direction of the workbench 1 .

[0047] The processing table 6 is slidably connected with a support frame 7, and the support frame 7 moves along the height direction of the workbench 1. The processing table 6 is fixedly connected with a fourth guide rail 71 and a fourth motor 72, and the two fourth guide rails 71 are vertically arranged. The support frame 7 is slidably connected to the fourth guide rail 71. The fourth motor 72 is located at the lower end of the processing table 6. The fourth screw is fixedly connected to the fourth motor 72, and the fourth screw is threadedly connected to the support frame 7. The fourth guide rail 71 and the fourth screw are both arranged along the height direction of the workbench 1.

[0048] The fourth motor 72 is turned on, and the fourth screw is rotated. Through the conduction effect of the thread, the support frame 7 moves along the length direction of the fourth guide rail 71, that is, the support frame 7 moves along the height direction of the workbench 1.

[0049] A rough planer 81 and a fine planer 82 are fixedly connected to the support frame 7. A fifth motor 84 is fixedly connected to the support frame 7, and a milling cutter 83 is rotatably connected to the support frame 7. When the fifth motor 84 is started, the milling cutter 83 can be rotated.

[0050] The workbench is provided with a material cutting slope 91, which is located below the rough planer 81 and the fine planer 82. A material cutting opening 92 is provided on the side wall of the workbench 1, and the material cutting opening 92 corresponds to the material cutting slope 91.

[0051] One end of the worm 10 is fixed by the three-jaw chuck 21, and the other end of the worm 10 is pressed against the top 5. The support frame 7 moves and makes the milling cutter 83 correspond to the worm 10, and the positioning platform 2 drives the worm 10 to move so that the milling cutter 83 is located inside the worm 10. When the milling cutter 83 rotates, a cutter groove can be formed on the worm 10. Then the positioning platform 2 drives the worm 10 to reset, and then the roughing cutter 81 and the fine planing cutter 82 correspond to the worm 10 in turn. The positioning platform 2 moves back and forth to form a keyway on the worm 10.

[0052] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementations. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
