Description

Technical Field

[0001] This utility model relates to the field of planer technology, and in particular to a clamping structure for planers. Background Technology

[0002] A planer is a linear motion machine tool that uses a planing tool to plan the plane, groove, or shaped surface of a workpiece. Machining with a planer requires relatively simple tools, but the productivity is low (except for machining long and narrow planes). Therefore, it is mainly used for single-piece and small-batch production and machine repair shops, and is often replaced by milling machines in mass production.

[0003] The existing clamping structure of the planer can only clamp the end face of the workpiece. When machining workpieces with irregular shapes, the clamping is not firm enough, and the workpiece is prone to displacement during machining, which can affect the machining quality. At the same time, when machining different positions of the workpiece, it is necessary to reposition the workpiece, which is time-consuming and laborious and can affect the machining efficiency.

[0004] Therefore, it is necessary to provide a clamping structure for a planer to solve the above-mentioned technical problems. Utility Model Content

[0008] The clamping module includes a circular plate. One side of the circular plate is fixedly connected to the housing of a cylinder. The end of the telescopic rod of the cylinder is fixedly connected to a connecting block. The two sides of the connecting block are respectively connected to corresponding connecting rods by pin hinges. One end of each of the two connecting rods is respectively connected to a corresponding cross-shaped slider by pin hinges. The two cross-shaped sliders are respectively set in corresponding cross-shaped grooves. The two cross-shaped grooves are respectively set on the circular plate. The two cross-shaped sliders are respectively fixedly connected to the corresponding clamping plate.

[0009] The second clamping module includes a lead screw groove, which is located in the middle of the circular plate. Two sliders are provided in the lead screw groove, and the two sliders are respectively fixedly connected to the corresponding clamping plates. The two ends of the inner side of the lead screw groove are respectively movably connected to one end of a bidirectional lead screw. The two ends of the bidirectional lead screw are respectively provided with two sections of threads with opposite directions. The bidirectional lead screw is respectively threaded to the corresponding slider. One end of the bidirectional lead screw passes through one side of the lead screw groove, and the end of the bidirectional lead screw is fixedly connected to the center of the turntable.

[0010] Preferably, the adjustment module includes a worm gear, with corresponding protrusions movably connected to the central shafts at both ends of the worm gear. The two protrusions are respectively fixedly connected to the lower part of one side of the support plate. The end of the central shaft at one end of the worm gear is fixedly connected to the center of the turntable. The worm gear meshes with a worm wheel, which is fixedly connected to an annular plate.

[0011] Preferably, the annular hole is disposed on the support plate.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] A clamping structure for a planer includes a clamping module 1, a clamping module 2, a support plate 3, an adjustment module 4, and a mounting plate 5.

[0031] The clamping module 1 includes a circular plate 17. One side of the circular plate 17 is fixedly connected to the housing of the cylinder 11. The end of the telescopic rod of the cylinder 11 is fixedly connected to the connecting block 12. The two sides of the connecting block 12 are respectively connected to the corresponding connecting rods 13 by pin hinges. One end of the two connecting rods 13 is respectively connected to the corresponding cross-shaped sliders 14 by pin hinges. The two cross-shaped sliders 14 are respectively set in the corresponding cross-shaped slide grooves 15. The two cross-shaped slide grooves 15 are respectively set on the circular plate 17. The two cross-shaped sliders 14 are respectively fixedly connected to the corresponding clamping plate 16.

[0032] The clamping module 2 includes a lead screw groove 24, which is located in the middle of the circular plate 17. Two sliders 22 are provided in the lead screw groove 24, and the two sliders 22 are respectively fixedly connected to the corresponding clamping plates 25. The two ends of the inner side of the lead screw groove 24 are respectively movably connected to one end of a bidirectional lead screw 21. The two ends of the bidirectional lead screw 21 are respectively provided with two sections of threads with opposite thread directions. The bidirectional lead screw 21 is respectively threaded to the corresponding sliders 22. One end of the bidirectional lead screw 21 passes through one side of the lead screw groove 24, and the end of the bidirectional lead screw 21 is fixedly connected to the center of the turntable 23.

[0033] The adjustment module 4 includes a worm gear 42, with corresponding protrusions 46 movably connected to the central shafts at both ends of the worm gear 42. The two protrusions 46 are fixedly connected to the lower part of one side of the support plate 3. The end of the central shaft at one end of the worm gear 46 is fixedly connected to the center of the turntable 41. The worm gear 46 meshes with a worm wheel 43. The worm wheel 43 is fixedly connected to an annular plate 44. The annular plate 44 is movably connected to an annular hole 45. The annular plate 44 is fixedly connected to the circular plate 17.

[0034] The annular hole 45 is provided on the support plate 3.

[0035] The support plate 3 is fixedly connected to the mounting plate 5.

[0036] The mounting plate 5 is provided with a set of mounting holes 51.

[0037] Working principle: First, use a set of bolts to install the mounting plate 5 on the planer operating platform through the mounting holes 51. Place the workpiece to be processed between the two clamping plates 25. Rotate the turntable 23. The turntable 23 drives the double-acting screw 21 to rotate. The double-acting screw 21 drives the slider 22 to slide. The two sliders 22 drive the clamping plates 25 to move, so that the two clamping plates 25 clamp the end face of the workpiece. At this time, stop rotating the turntable 23 and start the cylinder 11. The extension rod of the cylinder 11 extends and drives the connecting block 12 to move. The connecting block 12 drives the corresponding connecting rod 13 to swing. The two connecting rods 13 drive the cross-shaped slider 14 to slide along the cross-shaped groove 15, so that the two cross-shaped sliders 14 drive the clamping plate 16 to clamp the other end face of the workpiece, realizing multi-directional clamping and fixing of the workpiece. At this time, close the cylinder 11 to avoid the workpiece from shifting during subsequent processing by the planer, thus avoiding affecting the processing quality of the workpiece.

[0038] Then, turntable 41 is rotated, which drives worm gear 42 to rotate. Worm gear 42 meshes with worm wheel 43 to rotate. Worm wheel 43 drives circular plate 17 to rotate along annular hole 45 through annular plate 44. This causes circular plate 17 to drive clamping module 1, clamping module 2, and workpiece to rotate, thereby achieving workpiece flipping. This allows the planer to process different positions of the workpiece, saving time and effort.

[0039] Beneficial effects: Through clamping module 1 and clamping module 2, the workpiece can be clamped and fixed in multiple directions, which can prevent the workpiece from shifting during subsequent processing by the planer, thus affecting the processing quality of the workpiece. Through adjustment module 4, the workpiece can be flipped, so that the planer can process different positions of the workpiece, saving time and effort.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
