Description

Technical Field

[0001] This utility model relates to the field of milling machine technology, and in particular to a novel milling machine positioning fixture. Background Technology

[0002] A milling machine is a versatile machine tool that can machine planes, grooves, geared parts, helical surfaces, and various curved surfaces. During operation, the workpiece is mounted on a fixture on the worktable. The milling cutter rotates as the primary motion, supplemented by the feed motion of the worktable or milling head, thus obtaining the desired machined surface.

[0003] Currently, existing milling machine positioning fixtures can only clamp one type of workpiece, either sheet metal or pipe fittings. To clamp different workpieces, the clamping clamps must be changed, which is time-consuming and labor-intensive. Therefore, to improve the processing efficiency of milling machines and to promote technological advancement and enhance core technological competitiveness in the industry, this application proposes a new implementation scheme that differs from the existing milling machine positioning fixture structure and application method. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that existing milling machine positioning fixtures can only clamp one type of plate or pipe fitting, and to propose a new type of milling machine positioning fixture.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel milling machine positioning fixture includes a clamping base and a mounting plate. A clamping block is slidably connected to the inner bottom wall of the clamping base. Two first guide rods are fixedly connected to one side of the clamping block, and the other ends of the first guide rods pass through one end of the clamping base and are slidably connected to it. A clamping screw is threadedly connected to one end of the clamping base, and one end of the clamping screw is rotatably connected to the clamping block. A movable clamping clamp is fixedly connected to one side of the clamping block, and a fixed clamping clamp is fixedly connected to the inner wall of one end of the clamping base. Rotating plates are provided at the top of both the fixed clamping clamp and the movable clamping clamp. A base is fixedly connected to the top of the block and the top of the clamping seat. A rotating rod is rotatably mounted on the top of the base through an interlocking bearing. The other end of the rotating rod is fixedly connected to one side of the rotating plate. A sliding groove and two guide grooves are provided on one side of the movable clamping clamp, one side of the fixed clamping clamp, and one side of the rotating plate. A sliding block is slidably connected in the sliding groove, and a guide block is slidably connected in the guide groove. A limit pressure block is fixedly connected to one side of the sliding block and the guide block. A first adjusting screw is threadedly connected to the top of the rotating plate. The bottom end of the first adjusting screw is rotatably connected to the top of the sliding block.

[0007] Furthermore, a second slide rail is fixedly connected to the top of the mounting plate, a second slider is slidably connected inside the second slide rail, and a third adjusting screw is rotatably installed between the inner walls of both ends of the second slide rail through an interlocking bearing. The second slider is threadedly connected to the third adjusting screw.

[0008] Furthermore, two third guide rods are fixedly connected between the inner walls of the two ends of the second slide, and the second slider is slidably sleeved with the third guide rods.

[0009] Furthermore, the top of the second slider is fixedly connected to the first slide rail, and the first slider is slidably connected inside the first slide rail. The top of the first slider is fixedly connected to the bottom of the clamping seat.

[0010] Furthermore, a second adjusting screw is rotatably mounted between the inner walls of the two ends of the first slide rail via an interlocking bearing, and the first slider is threadedly connected to the second adjusting screw.

[0011] Furthermore, two second guide rods are fixedly connected between the inner walls of the two ends of the first slide, and the first slider is slidably sleeved with the second guide rods.

[0012] Furthermore, the bottom inner wall of the clamping seat is provided with a chip removal groove.

[0013] Furthermore, the outer walls of the first adjusting screw, the second adjusting screw, and the third adjusting screw are all fitted with corrugated pipes.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. By rotating the rotating plate above the movable clamping clamp and the fixed clamping clamp, and by rotating the two rotating plates above the clamping block and the clamping seat respectively, clamping of pipes or plates can be achieved, thereby improving the applicability of the clamp.

[0016] 2. By turning the clamping screw, the movable clamping clamp moves closer to the fixed clamping clamp, thereby clamping the pipe from both sides. Then, turning the first adjusting screw causes the sliding block to move in the sliding groove, so that the limiting pressure block presses on both sides above the pipe, thereby firmly clamping the pipe for subsequent processing.

[0017] 3. The bellows design prevents debris from falling onto the first, second, and third adjusting screws, thus avoiding interference with their rotation and consequently affecting processing efficiency. Attached Figure Description

[0024] 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.

[0025] Reference Figures 1-5 A novel milling machine positioning fixture includes a clamping base 1 and a mounting plate 26. A clamping block 3 is slidably connected to the bottom inner wall of the clamping base 1. Two first guide rods 2 are welded to one side of the clamping block 3. The other end of the first guide rod 2 passes through one end of the clamping base 1 and is slidably connected to the clamping base 1. A clamping screw 4 is threaded to one end of the clamping base 1. One end of the clamping screw 4 is rotatably connected to the clamping block 3. A movable clamping clamp 6 is fixed to one side of the clamping block 3 by bolts. A fixed clamping clamp 7 is fixed to the inner wall of one end of the clamping base 1 by bolts. Tightening the clamping screw 4 causes the first guide rods 2 to move on the clamping base 1, thereby driving the movable clamping clamp 6 to move closer to the fixed clamping clamp 7, and thus clamping the plate.

[0026] The top of the fixed clamping clamp 7 and the top of the movable clamping clamp 6 are both equipped with rotating plates 8. The rotating plates 8 are rotated to be placed above the movable clamping clamp 6 and the fixed clamping clamp 7, and the two rotating plates 8 are rotated to be placed above the clamping block 3 and the clamping seat 1 respectively, so as to facilitate the clamping of pipes or plates. The top of the clamping block 3 and the top of the clamping seat 1 are both welded with bases 11. The top of the base 11 is rotatably mounted with a rotating rod 12 through an interlocking bearing. The other end of the rotating rod 12 is fixedly connected to one side of the rotating plate 8.

[0027] One side of the movable clamping clamp 6, one side of the fixed clamping clamp 7, and one side of the rotating plate 8 are all provided with a sliding groove 9 and two guide grooves 10. A sliding block 15 is slidably connected in the sliding groove 9, and a guide block 14 is slidably connected in the guide groove 10. One side of the sliding block 15 and the guide block 14 are fixed with a limit pressure block 13 by bolts. The top of the rotating plate 8 is threadedly connected with a first adjusting screw 16. The bottom end of the first adjusting screw 16 is rotatably connected to the top of the sliding block 15. Tightening the first adjusting screw 16 causes the sliding block 15 to move in the sliding groove 9. At the same time, under the guiding action of the guide block 14 moving in the guide groove 10, the limit pressure block 13 is pressed on both sides above the pipe fitting.

[0028] The top of the mounting plate 26 is fixed with a second slide rail 20 by bolts. A second slider 23 is slidably connected inside the second slide rail 20. A third adjusting screw 25 is rotatably installed between the inner walls of the two ends of the second slide rail 20 through an embedded bearing. The second slider 23 is threadedly connected to the third adjusting screw 25. Two third guide rods 24 are welded between the inner walls of the two ends of the second slide rail 20. The second slider 23 is slidably sleeved with the third guide rod 24. Tightening the third adjusting screw 25 causes the second slider 23 to move along the third guide rod 24, thereby driving the workpiece to move longitudinally.

[0029] The top of the second slider 23 is fixed to the first slide rail 19 by bolts. The first slider 17 is slidably connected inside the first slide rail 19. The top of the first slider 17 is fixedly connected to the bottom of the clamping seat 1. The second adjusting screw 21 is rotatably installed between the inner walls of the two ends of the first slide rail 19 through an embedded bearing. The first slider 17 is threadedly connected to the second adjusting screw 21. Two second guide rods 22 are welded between the inner walls of the two ends of the first slide rail 19. The first slider 17 is slidably sleeved with the second guide rods 22. Tightening the second adjusting screw 21 causes the first slider 17 to move along the second guide rods 22, thereby driving the workpiece to move laterally.

[0030] The bottom inner wall of the clamping seat 1 is provided with a chip discharge groove 18, from which the chips are cleaned out;

[0031] The outer walls of the first adjusting screw 16, the second adjusting screw 21, and the third adjusting screw 25 are all fitted with bellows 5. One end of the bellows 5 of the first adjusting screw 16 is fixed to the inner wall of one end of the clamping seat 1 by bolts, and the other end of the bellows 5 is fixed to the clamping block 3 by bolts. One end of the bellows 5 of the second adjusting screw 21 is fixedly connected to the inner wall of one end of the first slide rail 19, and the other end of the bellows 5 is fixedly connected to one end of the first slider 17. One end of the bellows 5 of the third adjusting screw 25 is fixedly connected to the inner wall of one end of the second slide rail 20, and the other end of the bellows 5 is fixedly connected to the second slider 23. The bellows 5 prevent debris from falling on the first adjusting screw 16, the second adjusting screw 21, and the third adjusting screw 25, so as not to affect the rotation of the first adjusting screw 16, the second adjusting screw 21, and the third adjusting screw 25.

[0032] The working principle of this embodiment is as follows: When clamping the plate, firstly, rotate the rotating plate 8 horizontally so that the two rotating plates 8 are respectively rotated to be placed above the clamping block 3 and the clamping seat 1. At this time, the guide block 14 and the sliding block 15 are located in the guide groove 10 and the sliding groove 9 of the rotating plate 8. Then, place the plate on the bottom inner wall of the clamping seat 1 and between the movable clamping clamp 6 and the fixed clamping clamp 7. Then, turn the clamping screw 4 to move the first guide rod 2 on the clamping seat 1, thereby driving the movable clamping clamp 6 to move closer to the fixed clamping clamp 7, and thus clamping the plate.

[0033] When clamping the pipe fitting, firstly, rotate the rotating plate 8 to a position above the movable clamping clamp 6 and the fixed clamping clamp 7. Then, place the pipe fitting on the bottom inner wall of the clamping seat 1. Next, turn the clamping screw 4 to move the first guide rod 2 on the clamping seat 1, thereby driving the movable clamping clamp 6 closer to the fixed clamping clamp 7, and clamping the pipe fitting from both sides. Then, turn the first adjusting screw 16 to move the sliding block 15 in the sliding groove 9. At the same time, under the guiding action of the guide block 14 moving in the guide groove 10, the limiting pressure block 13 presses on both sides above the pipe fitting, thereby firmly clamping the pipe fitting.

[0034] After clamping, turn the third adjusting screw 25 to move the second slider 23 along the third guide rod 24, thereby driving the workpiece to move longitudinally. Then, turn the second adjusting screw 21 to move the first slider 17 along the second guide rod 22, thereby driving the workpiece to move laterally, thus adjusting the position of the workpiece so that the workpiece is aligned with the machining tool. After machining, the chips generated are manually discharged from the chip discharge groove 18. After the above adjusting screws are adjusted, tighten the nuts to lock them to maintain stability.

[0035] 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.
