DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be apparently and completely described in conjunction with the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative efforts fall within the protection scope of the utility model.

[0021] Please refer to Figures 1-4 The utility model provides a kind of technical scheme: a kind of adjustable metal fixture clamping device, including bottom plate 1 and movable block 5, the top of bottom plate 1 both sides are fixed with fixed block 2, fixed block 2 is provided with left and right moving mechanism, left and right moving mechanism is provided with clamping head 8, movable block 5 is attached with clamping head 8 on another side, and the bottom of clamping head 8 and the top of bottom plate 1 are mutually attached, movable block 5 and clamping head 8 connection place are provided with quick dismounting mechanism;

[0022] The quick disassembly mechanism includes limiting blocks 9. Three limiting blocks 9 are fixed at equal intervals on one side of the clamping head 8. The limiting blocks 9 are engaged inside the limiting groove 10. The limiting groove 10 is opened on one side of the movable block 5. The movable block 5 has a first sliding groove 11 inside. A pull rod 12 is slidably installed inside the first sliding groove 11. A through groove 13 is opened on the inner side of the first sliding groove 11. A second sliding groove 14 is opened on the inner side of the through groove 13. A movable rod 15 is fixed to the outer wall of the pull rod 12. The end of the movable rod 15 passes through the inside of the through groove 13 and is fixedly connected to the end of one side of the locking rod 17. The movable rod 15 is slidably connected to the through groove 13. The outer wall of the movable rod 15 is fixedly connected to one end of the spring 16. The other end of the spring 16 is fixedly connected to the inner wall of the through groove 13. The locking rod 17 is slidably installed inside the second sliding groove 14. The end of the locking rod 17 is engaged inside the locking groove 18. The locking groove 18 is opened on one side of the limiting block 9.

[0023] The left and right moving mechanism includes a first lead screw 3, which is threaded through the middle of the fixed block 2. A first handle 4 is fixed to one end of the first lead screw 3, and the other end of the first lead screw 3 is rotatably connected to the center of one side of the movable block 5 through a bearing. The bottom of the movable block 5 is in contact with the top of the base plate 1. A limit rod 6 is fixed to one end of the movable block 5. The end of the limit rod 6 passes through the interior of the limit hole 7, and the limit rod 6 is slidably connected to the limit hole 7. The limit hole 7 is opened at the end of the fixed block 2, and an anti-slip mechanism is provided above the limit rod 6.

[0024] The end of the pull rod 12 is provided with a pull hole 19 on the outside of the movable block 5, so that the user can pull the pull rod 12.

[0025] A first rubber sheet 20 is fixed on one side of the clamping head 8 away from the movable block 5, which protects the workpiece.

[0026] The anti-slip mechanism includes a groove 21. The top of the limiting hole 7 has a groove 21. A clamping plate 22 is slidably installed inside the groove 21. The bottom of the clamping plate 22 has an arc-shaped groove 23. A second rubber sheet 24 is fixed inside the arc-shaped groove 23. A second lead screw 25 is rotatably installed at the center of the top of the clamping plate 22 via a bearing. The top of the second lead screw 25 passes through the top of the fixing block 2 and is fixed with a second handle 26. The second lead screw 25 and the fixing block 2 are threadedly connected. By rotating the second handle 26 forward or backward, the clamping plate 22, the arc-shaped groove 23 and the second rubber sheet 24 can be moved upward or downward, so that the second rubber sheet 24 can be tightly attached to the outside of the limiting rod 6, which is conducive to fixing the limiting rod 6, thus facilitating the fixing of the clamping head 8, and further facilitating the fixing of the workpiece by the clamping head 8.

[0027] The movable rod 15, spring 16 and locking rod 17 are all distributed at equal intervals on one side of the pull rod 12, which ensures that when the pull rod 12 is pulled, the pull rod 12 can pull the three locking rods 17 to move simultaneously and separate from the three locking slots 18.

[0028] Working principle: When using this adjustable metal jig clamping device, first place the cylindrical workpiece on the top of the base plate 1 and between the two clamping heads 8. Then rotate the first handle 4, which drives the first lead screw 3 to rotate. Since the first lead screw 3 and the fixed block 2 are threadedly connected, the end of the first lead screw 3 is rotatably connected to the center of one side of the movable block 5 through a bearing. The limiting rod 6 is slidably connected to the limiting hole 7. Therefore, the first lead screw 3 pushes the movable block 5 and the clamping head 8 to move closer to the other clamping head 8, so that the two clamping heads 8 clamp and fix the cylindrical workpiece.

[0029] Rotating the second handle 26 causes the second lead screw 25 to rotate. Since the second lead screw 25 is threadedly connected to the fixing block 2, and the second lead screw 25 is rotatably mounted at the center of the top of the clamping plate 22 via a bearing, and the clamping plate 22 is slidably mounted inside the groove 21, the second lead screw 25 pushes the clamping plate 22, the arc groove 23, and the second rubber sheet 24 to move downwards simultaneously, so that the inner side of the second rubber sheet 24 is in close contact with the top of the limiting rod 6, thus fixing the limiting rod 6. This prevents the clamping head 8 from being fixed solely by the threaded connection between the fixing block 2 and the first lead screw 3, improving the stability of the clamping head 8 in fixing the workpiece.

[0030] When it is necessary to replace the clamping head 8 with another shape, pull the lever 12. The lever 12 drives the three movable rods 15 and the three locking rods 17 to move simultaneously, so that the ends of the three locking rods 17 separate from the three locking slots 18 at the same time. The three springs 16 are compressed at the same time. At this time, the three limiting blocks 9 are released from their restraints at the same time. Then move the clamping head 8. The clamping head 8 drives the three limiting blocks 9 to separate from the three limiting slots 10 at the same time, completing the quick disassembly of the clamping head 8. Then move the clamping head 8 with another shape, so that the three limiting blocks 9 on the clamping head 8 engage with the three limiting slots 10 at the same time. Release the lever 12. Under the elastic force of the three springs 16, the ends of the three locking rods 17 engage with the three locking slots 18 at the same time, quickly completing the fixation of the replaced clamping head 8.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
